CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

        This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, or the Exchange Act, which reflect our current views with respect to, among other things, our operations and financial performance. You can identify these forward-looking statements by the use of words such as "outlook," "believe," "expect," "potential," "continue," "may," "should," "seek," "approximately," "predict," "intend," "will," "plan," "estimate," "anticipate", the negative version of these words, other comparable words or other statements that do not relate strictly to historical or factual matters. Forward-looking statements are subject to various risks and uncertainties. Accordingly, there are or will be important factors that could cause actual outcomes or results to differ materially from those indicated in these statements. We believe these factors include but are not limited to those described under the section entitled "Risk Factors" in this report. These factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are included in this report and in our other periodic filings. We do not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise.

        In this report, references to "KKR," "we," "us," "our" and "our partnership" refer to KKR & Co. L.P. and its consolidated subsidiaries. Prior to KKR & Co. L.P. becoming listed on the New York Stock Exchange ("NYSE") on July 15, 2010, KKR Group Holdings L.P. ("Group Holdings") consolidated the financial results of KKR Management Holdings L.P. and KKR Fund Holdings L.P. (together, the "KKR Group Partnerships") and their consolidated subsidiaries. Each KKR Group Partnership has an identical number of partner interests and, when held together, one Class A partner interest in each of the KKR Group Partnerships together represents one KKR Group Partnership Unit.

        References to "our Managing Partner" are to KKR Management LLC, which acts as the general partner of KKR & Co. L.P. Unless otherwise indicated, references to equity interests in KKR's business, or to percentage interests in KKR's business, reflect the aggregate equity of the KKR Group Partnerships and are net of amounts that have been allocated to our principals in respect of the carried interest from KKR's business as part of our "carry pool" and certain minority interests. References to our "principals" are to our senior employees and non-employee operating consultants who hold interests in KKR's business through KKR Holdings L.P., which we refer to as "KKR Holdings", and references to our "senior principals" are to principals who also hold interests in our Managing Partner entitling them to vote for the election of its directors.

        Prior to October 1, 2009, KKR's business was conducted through multiple entities for which there was no single holding entity, but were under common control of senior KKR principals, and in which senior principals and KKR's other principals and individuals held ownership interests (collectively, the "Predecessor Owners"). On October 1, 2009, we completed the acquisition of all of the assets and liabilities of KKR & Co. (Guernsey) L.P. (f/k/a KKR Private Equity Investors, L.P. or "KPE") and, in connection with such acquisition, completed a series of transactions pursuant to which the business of KKR was reorganized into a holding company structure. The reorganization involved a contribution of certain equity interests in KKR's business that were held by KKR's Predecessor Owners to the KKR Group Partnerships in exchange for equity interests in the KKR Group Partnerships held through KKR Holdings. We refer to the acquisition of the assets and liabilities of KPE and to our subsequent reorganization into a holding company structure as the "KPE Transaction."

        In this report, the term "assets under management," or "AUM", represents the assets from which KKR is entitled to receive fees or a carried interest and general partner capital. We believe this measure is useful to unitholders as it provides additional insight into KKR's capital raising activities and the overall activity in its investment funds and vehicles. KKR calculates the amount of AUM as of

ii

Table of Contents

any date as the sum of: (i) the fair value of the investments of KKR's investment funds plus uncalled capital commitments from these funds; (ii) the fair value of investments in KKR's co-investment vehicles; (iii) the net asset value of certain of KKR's fixed income products; (iv) the value of outstanding structured finance vehicles and (v) the fair value of other assets managed by KKR. KKR's definition of AUM is not based on the definitions of AUM that may be set forth in agreements governing the investment funds, vehicles or accounts that it manages and is not calculated pursuant to any regulatory definitions.

        In this report, the term "fee paying assets under management," or "FPAUM", represents only those assets under management from which KKR receives fees. We believe this measure is useful to unitholders as it provides additional insight into the capital base upon which KKR earns management fees. This relates to KKR's capital raising activities and the overall activity in its investment funds and vehicles, for only those funds and vehicles where KKR receives fees (i.e., excluding vehicles that receive only carried interest or general partner capital). FPAUM is the sum of all of the individual fee bases that are used to calculate KKR's fees and differs from AUM in the following respects: (i) assets from which KKR does not receive a fee are excluded (i.e., assets with respect to which it receives only carried interest); and (ii) certain assets, primarily in its private equity funds, are reflected based on capital commitments and invested capital as opposed to fair value because fees are not impacted by changes in the fair value of underlying investments.

        In this report, the term "fee related earnings," or "FRE", is comprised of segment operating revenues less segment operating expenses and is used by management as an alternative measurement of the operating earnings of KKR and its business segments before investment income. We believe this measure is useful to unitholders as it provides additional insight into the operating profitability of our fee generating management companies and capital markets businesses. The components of FRE on a segment basis differ from the equivalent GAAP amounts on a consolidated basis as a result of: (i) the inclusion of management fees earned from consolidated funds that were eliminated in consolidation; (ii) the exclusion of fees and expenses of certain consolidated entities; (iii) the exclusion of charges relating to the amortization of intangible assets; (iv) the exclusion of charges relating to carry pool allocations; (v) the exclusion of non-cash equity charges and other non-cash compensation charges borne by KKR Holdings or incurred under the KKR & Co. L.P. 2010 Equity Incentive Plan; (vi) the exclusion of certain reimbursable expenses; and (vii) the exclusion of certain non-recurring items.

        In this report, the term "economic net income (loss)," or "ENI", is a measure of profitability for KKR's reportable segments and is used by management as an alternative measurement of the operating and investment earnings of KKR and its business segments. We believe this measure is useful to unitholders as it provides additional insight into the overall profitability of KKR's businesses inclusive of investment income and carried interest. ENI is comprised of: (i) FRE; plus (ii) segment investment income (loss), which is reduced for carry pool allocations and management fee refunds; less (iii) certain economic interests in KKR's segments held by third parties. ENI differs from net income (loss) on a GAAP basis as a result of: (i) the exclusion of the items referred to in FRE above; (ii) the exclusion of investment income (loss) relating to noncontrolling interests; and (iii) the exclusion of income taxes.

        You should note that our calculations of AUM, FPAUM, FRE, ENI and other financial measures may differ from the calculations of other investment managers and, as a result, our measurements of AUM, FPAUM, FRE, ENI, and other financial measures may not be comparable to similar measures presented by other investment managers. For important information regarding these and other financial measures, please see "Management's Discussion and Analysis of Financial Condition & Results of Operations—Segment Operating and Performance Measures."

        References to "our funds" or "our vehicles" refer to the investment funds, vehicles and/or accounts advised, sponsored or managed by one or more subsidiaries of KKR, unless the context requires otherwise.

        In this report, the term "GAAP" refers to generally accepted accounting principles in the United States.

        Unless otherwise indicated, references in this report to our fully diluted common units outstanding, or to our common units outstanding on a fully diluted basis, reflect (i) actual common units outstanding, (ii) common units into which KKR Group Partnership Units not held by us are exchangeable pursuant to the terms of the exchange agreement described in this report and (iii) common units issuable pursuant to any equity awards actually issued under the KKR & Co. L.P. 2010 Equity Incentive Plan, which we refer to as our "Equity Incentive Plan," but do not reflect common units available for issuance pursuant to our Equity Incentive Plan for which grants have not yet been made.

PART I

ITEM 1.    BUSINESS

Overview

        Led by Henry Kravis and George Roberts, we are a leading global investment firm with $75.5 billion in AUM as of December 31, 2012 and a 36-year history of leadership, innovation and investment excellence. When our founders started our firm in 1976, they established the principles that guide our business approach today, including a patient and disciplined investment process; the alignment of our interests with those of our fund investors, portfolio companies and other stakeholders; and a focus on attracting world class talent.

        Our business offers a broad range of investment management services to our fund investors and provides capital markets services to our firm, our portfolio companies and other third parties. Throughout our history, we have consistently been a leader in the private equity industry, having completed more than 200 private equity investments with a total transaction value in excess of $470 billion. In recent years, we have grown our firm by expanding our geographical presence and building businesses in new areas, such as fixed income, equity strategies, hedge fund solutions, capital markets, infrastructure, natural resources and real estate. Our new efforts build on our core principles and industry expertise, allowing us to leverage the intellectual capital and synergies in our businesses, and to capitalize on a broader range of the opportunities we source. Additionally, we have increased our focus on servicing our existing fund investors and have increased our investment in developing relationships with new investors in our funds.

        We conduct our business with offices throughout the world, providing us with a pre-eminent global platform for sourcing transactions, raising capital and carrying out capital markets activities. Our growth has been driven by value that we have created through our operationally focused investment approach, the expansion of our existing businesses, our entry into new lines of business, innovation in the products that we offer investors in our funds, an increased focus on providing tailored solutions to our clients and the integration of capital markets distribution activities.

        As a global investment firm, we earn management, monitoring, transaction and incentive fees for providing investment management, monitoring and other services to our funds, vehicles, managed accounts, specialty finance company and portfolio companies, and we generate transaction-specific income from capital markets transactions. We earn additional investment income from investing our own capital alongside that of our fund investors and from the carried interest we receive from our funds and certain of our other investment vehicles. A carried interest entitles the sponsor of a fund to a specified percentage of investment gains that are generated on third-party capital that is invested.

        We seek to consistently generate attractive investment returns by employing world-class people, following a patient and disciplined investment approach and driving growth and value creation in the assets we manage. Our investment teams have deep industry knowledge and are supported by a substantial and diversified capital base, an integrated global investment platform, the expertise of operating consultants and senior advisors and a worldwide network of business relationships that provide a significant source of investment opportunities, specialized knowledge during due diligence and substantial resources for creating and realizing value for stakeholders. We believe that these aspects of our business will help us continue to expand and grow our business and deliver strong investment performance in a variety of economic and financial conditions.

Our Firm

Global Operations

        With offices around the world, we have established ourselves as a leading global investment firm. We have multilingual and multicultural investment teams with local market knowledge and significant business, investment, and operational experience in the countries in which we invest. We believe that our global capabilities have helped us to raise capital, capture a greater number of investment opportunities, and assist our portfolio companies in their increasing reliance on global markets and sourcing, while enabling us to diversify our operations.

        Though our operations span multiple continents and asset classes, our investment professionals are supported by an integrated infrastructure and operate under a common set of principles and business practices that are monitored by a variety of committees. The firm operates with a single culture that rewards investment discipline, creativity, determination, and patience and the sharing of information, resources, expertise, and best practices across offices and asset classes. When appropriate, we staff transactions across multiple offices and businesses in order to take advantage of the industry-specific expertise of our investment professionals, and we hold regular meetings in which investment professionals throughout our offices share their knowledge and experiences. We believe that the ability to draw on the local cultural fluency of our investment professionals while maintaining a centralized and integrated global infrastructure distinguishes us from other investment firms and has been a substantial contributing factor to our ability to raise funds, invest internationally, and expand our businesses.

Our Segments

Private Markets

        Through our Private Markets segment, we manage and sponsor a group of private equity funds and co-investment vehicles that invest capital for long-term appreciation, either through controlling ownership of a company or strategic minority positions. We also manage and source investments in infrastructure, natural resources and real estate. These funds, vehicles and accounts are managed by Kohlberg Kravis Roberts & Co. L.P., an SEC registered investment adviser. As of December 31, 2012, the segment had $49.1 billion of AUM and our actively investing funds included geographically differentiated investment funds and vehicles.

(1)

For the years 2006 through 2008, assets under management are presented pro forma for the KPE Transaction, and therefore, exclude the net asset value of KPE and its former commitments to our investment funds.

(2)

As of December 31, 2012, we had $4.0 billion of commitments (including our general partner commitment) to our Asian Fund II, $1.1 billion of unallocated commitments from a strategic partnership with a state pension plan, and approximately $2.5 billion in connection with other infrastructure, natural resources and other private equity funds and co-investment vehicles, which are not reflected in the table above. Such commitments will not contribute to AUM until we are entitled to receive fees or a carried interest in accordance with our definition of AUM and consequently are not included in AUM as of December 31, 2012.

        The table below presents information as of December 31, 2012 relating to our active private equity funds and other Private Markets investment vehicles for which we have the ability to earn carried interest. This data does not reflect acquisitions or disposals of investments, changes in investment values or distributions occurring after December 31, 2012.

Performance

        We take a long-term approach to Private Markets investing and measure the success of our investments over a period of years rather than months. Given the duration of these investments, the firm focuses on realized multiples of invested capital and IRRs when deploying capital in these transactions. We have more than doubled the value of capital that we have invested in our Private Markets investment funds, turning $56.1 billion of capital into $113.7 billion of value from our inception in 1976 to December 31, 2012. Over the same time period, our realized and partially realized investments have grown from $30.6 billion to $88.4 billion.

Amount Invested and Total Value for
Private Markets Investment Funds
As of December 31, 2012

        From our inception in 1976 through December 31, 2012, our investment funds with at least 36 months of investment activity generated a cumulative gross IRR of 25.7%, compared to the 11.4% and 8.5% gross IRR achieved by the S&P 500 Index and MSCI World Index, respectively, over the same period, despite the cyclical and sometimes challenging environments in which we have operated. The S&P 500 Index and MSCI World Index are unmanaged indices and our returns assume reinvestment of distributions and do not reflect any fees or expenses.

        The tables below present information as of December 31, 2012 relating to the historical performance of certain of our Private Markets investment vehicles since inception, which we believe illustrates the benefits of our investment approach. The information presented under Total Investments includes all of the investments made by the specified investment vehicle, while the information presented under Realized/Partially Realized Investments includes only those investments for which realized proceeds, excluding current income like dividends and interest, are a material portion of invested capital. This data does not reflect additional capital raised since December 31, 2012 or

Private Equity

        We are a world leader in private equity, having raised 17 funds with approximately $66.7 billion of capital commitments through December 31, 2012. We invest in industry-leading franchises and attract world-class management teams. Our investment approach leverages our capital base, sourcing advantage, global network and industry knowledge. It also leverages our sizeable team of operating consultants who work exclusively with our portfolio companies, as well as our senior advisors, many of whom are former chief executive officers and leaders of the business community.

Portfolio

        The following chart presents information concerning the amount of capital invested by private equity funds by geography through December 31, 2012. We believe that this data illustrates the benefits of our business approach and our ability to source and invest in deals in multiple geographies and industries.

Table of Contents

        Our current private equity portfolio consists of over 80 companies with more than $210 billion of annual revenues. These companies are headquartered in 19 countries and operate in 15 general industries which take advantage of our broad and deep industry and operating expertise. Many of these companies are leading franchises with global operations, strong management teams and attractive growth prospects, which we believe will provide benefits through a broad range of business conditions.

Investment Approach

        Our approach to making private equity investments focuses on achieving multiples of invested capital and attractive risk-adjusted IRRs by selecting high-quality investments that may be made at attractive prices, applying rigorous standards of due diligence when making investment decisions, implementing strategic and operational changes that drive growth and value creation in acquired businesses, carefully monitoring investments, and making informed decisions when developing investment exit strategies.

        We believe that we have achieved a leading position in the private equity industry by applying a disciplined investment approach and by building strong partnerships with highly motivated management teams who put their own capital at risk. When making private equity investments, we seek out strong business franchises, attractive growth prospects, leading market positions, and the ability to generate attractive returns. We do not participate in "hostile" transactions that are not supported by a target company's board of directors.

Sourcing and Selecting Investments

        We have access to significant opportunities for making private equity investments as a result of our sizeable capital base, global platform, and relationships with leading executives from major companies, commercial and investment banks, and other investment and advisory institutions. Members of our global network frequently contact us with new investment opportunities, including a substantial number of exclusive investment opportunities and opportunities that are made available to only a very limited number of other firms. We also proactively pursue business development strategies that are designed to generate deals internally based on the depth of our industry knowledge and our reputation as a leading financial sponsor.

        To enhance our ability to identify and consummate private equity investments, we have organized our investment professionals in industry-specific teams. Our industry teams work closely with our operating consultants and senior advisors to identify businesses that can be grown and improved. These teams conduct their own primary research, develop a list of industry themes and trends, identify companies and assets in need of operational improvement, and seek out businesses and assets that they believe will benefit from our involvement. They possess a detailed understanding of the economic drivers, opportunities for value creation, and strategies that can be designed and implemented to improve companies across the industries in which we invest.

Due Diligence and the Investment Decision

        When an investment team determines that an investment proposal is worth consideration, the proposal is formally presented to the applicable regional or strategy oriented investment committee and the due diligence process commences if appropriate. The objective of the due diligence process is to identify attractive investment opportunities based on the facts and circumstances surrounding an investment and to prepare a framework that may be used from the date of an acquisition to drive operational improvement and value creation. When conducting due diligence, investment teams evaluate a number of important business, financial, tax, accounting, environmental, social, governance, legal and regulatory issues in order to determine whether an investment is suitable. In connection with the due diligence process, investment professionals spend significant amounts of time meeting with a company's management and operating personnel, visiting plants and facilities, and where appropriate, speaking with other stakeholders interested in and impacted by the investment in order to understand

8

---

Table of Contents

the opportunities and risks associated with the proposed investment. Our investment professionals also use the services of outside accountants, consultants, lawyers, investment banks, and industry experts as appropriate to assist them in this process. An investment committee monitors all due diligence practices and must approve an investment before it may be made.

Building Successful and Competitive Businesses

        Portfolio management committees are responsible for working with our investment professionals from the date on which an investment is made until the time it is exited in order to ensure that strategic and operational objectives are accomplished and that the performance of the investment is closely monitored. When investing in a portfolio company, we partner with world-class management teams to execute on our investment thesis, and we rigorously track performance through regular monitoring of detailed operational and financial metrics as well as appropriate environmental, social and governance issues. We have developed a global network of experienced managers and operating executives who assist the portfolio companies in making operational improvements and achieving growth. We augment these resources with operational guidance from operating consultants at KKR Capstone, senior advisors, and investment teams, and with "100-Day Plans" that focus the firm's efforts and drive our strategies. We emphasize efficient capital management, top-line growth, R&D spending, geographical expansion, cost optimization, and investment for the long-term.

Realizing Investments

        We have developed substantial expertise for realizing private equity investments. From our inception through December 31, 2012, the firm has generated approximately $79.2 billion of cash proceeds from the sale of our private equity portfolio companies in initial public offerings and secondary offerings, dividends, and sales to strategic buyers. When exiting investments, our objective is to structure the exit in a manner that optimizes returns for fund investors and, in the case of publicly traded companies, minimizes the impact that the exit has on the trading price of the company's securities. We believe that our ability to successfully realize investments is attributable in part to the strength and discipline of our portfolio management committees and capital markets business, as well as the firm's longstanding relationships with corporate buyers and members of the investment banking and investing communities.

Private Equity Fund Structures

        The private equity funds that we sponsor and manage have finite lives and investment periods. Each fund is organized as a single partnership or a combination of separate domestic and overseas partnerships, and each partnership is controlled by a general partner. Private equity fund investors are limited partners who agree to contribute a specified amount of capital to the fund from time to time for use in qualifying investments during the investment period, which generally lasts up to six years depending on how quickly capital is deployed. The investment period for certain funds may be terminated upon supermajority vote (based on capital commitment) of the fund's limited partners or by the fund's advisory committee. The term of our private equity funds generally end 10 to 12 years from the date of the fund's first or last investment, subject to a limited number of extensions with the consent of the limited partners or the applicable advisory committee. Given the length of the investment periods and terms of our private equity funds and the limited conditions under which such periods can be terminated and commitments may be withdrawn, the AUM of our private equity funds provide a long-term stable capital base.

        Each private equity fund's general partner is generally entitled to a carried interest that allocates to it 20% of the net profits realized by the limited partners from the fund's investments. Our newest private equity funds, the North America Fund XI and our Asian Fund II (which is not active) have a performance hurdle which requires that we return 7%, compounded annually, to limited partners in the fund prior to receiving our 20% share of net profits realized by limited partners. Such performance

Table of Contents

hurdles are subject to a catch-up allocation to the general partner after the hurdle has been reached. Our earlier private equity funds do not include a performance hurdle. The timing of receipt of carried interest in respect of investments of our carry funds is dictated by the terms of the partnership agreements that govern such funds, and is distributed to the general partner of a private equity fund only after all of the following are met: (i) a realization event has occurred (e.g., sale of a portfolio company, dividend, etc.); (ii) the vehicle has achieved positive overall investment returns since its inception, in excess of performance hurdles where applicable; and (iii) with respect to investments with a fair value below cost, proceeds have been returned to fund investors in an amount sufficient to reduce remaining cost to the investments' fair value. For a fund that has a fair value above cost, overall, but has one or more investments where fair value is below cost, the shortfall between cost and fair value for such investments is referred to as a "netting hole." See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity—Sources of Liquidity" for a discussion of netting holes. Net realized profit or loss is not netted between or among funds except for the Annex Fund as discussed below under "—Other Private Equity Investment Vehicles—E2 Investors (Annex Fund)". In addition, the agreements governing KKR's private equity funds generally include a "clawback" or, in certain instances, a "net loss sharing" provision that, if triggered, may give rise to a contingent obligation that may require the general partner to return or contribute amounts to the fund for distribution to investors at the end of the life of the fund. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies—Clawback Provision", "Management's Discussion and Analysis of Financial Condition—Critical Accounting Policies—Net Loss Sharing Provision" and "Risk Factors—The "clawback" or "net loss sharing" provisions in our governing agreements may give rise to a contingent obligation that may require us to return or contribute amounts to our funds and fund investors."

        We enter into management agreements with our private equity funds pursuant to which we receive management fees in exchange for providing the funds with management and other services. Gross management fees for our private equity funds generally range from 1% to 2% of committed capital during the fund's investment period and is generally 0.75% of invested capital after the expiration of the fund's investment period with subsequent reductions over time, which causes the fees to be reduced as investments are liquidated. These management fees are paid by private equity fund investors, who generally contribute capital to the fund in order to allow the fund to pay the fees to us. Our private equity funds generally require that management fees be returned to fund investors before a carried interest may be paid.

        We also enter into monitoring agreements with our portfolio companies pursuant to which we receive periodic monitoring fees in exchange for providing them with management, consulting, and other services, and we typically receive transaction fees from portfolio companies for providing them with financial, advisory and other services in connection with specific transactions. In some cases, we may be entitled to other fees that are paid by an investment target upon closing a transaction or when a potential investment is not consummated. Our private equity fund agreements typically require us to share 80% to 100% of any monitoring, transaction and other fees that are allocable to a fund (after reduction for expenses incurred allocable to a fund from unconsummated transactions) with fund investors.

        In addition, the agreements governing our private equity funds enable investors in those funds to reduce their capital commitments available for further investments, on an investor-by-investor basis, in the event certain "key persons" (for example, both of Messrs. Kravis and Roberts, and, in the case of certain geographically or product focused funds, one or more of the executives focused on such funds) cease to be actively involved in the management of the fund. While these provisions do not allow investors in our funds to withdraw capital that has been invested or cause a fund to terminate, the occurrence of a "key man" event could cause disruption in our business, reduce the amount of capital that we have available for future investments, and make it more challenging to raise additional capital in the future.

        To the extent investors in our private equity funds suffer losses resulting from fraud, gross negligence, willful misconduct or other similar misconduct, investors may have remedies against us, our private equity funds, our principals, or our affiliates under the federal securities laws and state laws. While the general partners and investment advisers to our private equity funds, including their directors, officers, other employees, and affiliates, are generally indemnified by the private equity funds to the fullest extent permitted by law with respect to their conduct in connection with the management of the business and affairs of our private equity funds, such indemnity does not extend to actions determined to have involved fraud, gross negligence, willful misconduct or other similar misconduct.

        Because private equity fund investors typically are unwilling to invest their capital in a fund unless the fund's manager also invests its own capital in the fund's investments, our private equity fund documents generally require the general partners of the funds to make minimum capital commitments to the funds. The amounts of these commitments, which are negotiated by fund investors, generally range from 2% to 4% of a fund's total capital commitments at final closing. When investments are made, the general partner contributes capital to the fund based on its fund commitment percentage and acquires a capital interest in the investment that is not subject to a carried interest or management fees. Prior to the KPE Transaction, these capital contributions were funded with cash from operations that otherwise would be distributed to our principals. Subsequent to the KPE Transaction, these general partner commitments are made through our Capital Markets and Principal Activities segment.

Other Private Equity Investment Vehicles

        E2 Investors (Annex Fund).    We established the Annex Fund in 2009 to enable fund investors in the European Fund II and the Millennium Fund to make additional investments in portfolio companies of the European Fund II, which had already been fully invested. This fund has several features that distinguish it from our other private equity funds, including: (i) it does not pay a management fee to us; (ii) its general partner is only entitled to a carried interest after netting any losses, costs, and expenses relating to European Fund II and certain Millennium Fund investments from the profits of the Annex Fund investments; and (iii) no transaction or incremental monitoring fees are charged in connection with investments in which the Annex Fund participates.

        Other Private Equity Products.    We have offered significant co-investment opportunities to both fund investors and other third parties. We have built out our capital markets and distribution capabilities and created new investment structures and products that allow us to syndicate a portion of the equity needed to finance acquisitions. These structures include co-investment vehicles and a principal-protected private equity product, which generally entitles the firm to receive management fees and/or a carried interest. As of December 31, 2012, we had $2,255.7 million of AUM in products of this type. In addition, we manage certain separately managed accounts in the form of separate investment vehicles based on terms that are separately negotiated with investors in those vehicles.

Other Private Markets Investment Strategies

Natural Resources

        We manage investments in natural resources assets, such as oil and natural gas properties. In 2010 we launched our first dedicated energy fund, the KKR Natural Resources Fund, which seeks to acquire and operate oil and natural gas properties in mature basins located primarily in the United States. In acquiring these properties, which are typically considered to be non-core by their sellers, we seek to generate value through optimizing production around the acquired properties (via workovers and other operational initiatives), reducing operating costs, and optimizing commercial and marketing arrangements.

        Since the launch of the KKR Natural Resources Fund, we have invested in our capabilities, both with respect to our team of investment professionals and our relationships with technical partners. With these capabilities, we have expanded our natural resources strategy to target real asset investment

Table of Contents

opportunities across the upstream and midstream segments of the oil and gas industry. As part of this effort, we have completed investments in oil and gas drilling development transactions with operating companies and have also acquired mineral and royalty interests. As of December 31, 2012, we had received $1,225.8 million of capital commitments to our Natural Resources Fund and $1,011.3 million of capital commitments to this strategy through separately managed accounts.

        Our natural resources business aims to deliver current returns to fund investors through distributions generated by producing and selling the oil and natural gas reserves of these acquired properties and providing fund investors with exposure to commodity prices and the optionality of future drilling and production. We work closely with external teams of technical and operational experts to assist in the selection, evaluation and operation of investments.

Infrastructure

        We manage investments in infrastructure assets in order to capitalize on the growing demand for global infrastructure investment, and began investing through our first dedicated infrastructure fund in 2011. We believe that the global infrastructure market provides an opportunity for the firm's combination of private investment, operational improvement, and stakeholder engagement skills. This strategy seeks to achieve returns through the acquisition and operational improvement of assets important to the functioning of the economy and also to provide current income. Through this strategy we have made investments in transportation and parking, alternative energy, water and waste management and utilities. As of December 31, 2012, we had received $1,041.7 million of capital commitments to our Infrastructure Fund and $1,358.5 million of capital commitments to this strategy through separately managed accounts.

Real Estate

        We have hired several experienced real estate investment executives since 2011, who are developing a dedicated real estate strategy. As of December 31, 2012, we have committed $300 million of seed capital to develop this strategy. In addition, we have the flexibility to invest in real estate transactions across the capital structure through various vehicles, including our private equity and alternative credit funds. This platform targets real estate opportunities, including direct investments in real property, debt, special situations transactions and businesses with significant real estate holdings that can benefit from KKR's operational expertise. We seek to partner with real estate owners, lenders, operators, and developers to provide flexible capital to respond to transaction specific needs, including the outright purchase or financing of existing assets or companies and the funding of future development or acquisition opportunities. Through this strategy, we have made real estate investments in residential and commercial assets.

Other Private Markets Fund Structures

        While we have not yet established a dedicated fund for our real estate strategy, our natural resources and infrastructure funds have investment periods of up to 6 years with a fund term of approximately 12 years or longer. Management fees for such funds range from 1% to 2% on commitments or net asset value during investment period and on unreturned contributions for investments thereafter, subject to certain adjustments. These funds generally have an 8% performance hurdle subject to a catch-up allocation to the general partner after the hurdle has been reached, and thereafter the general partners of such funds share in 10% to 12.5% of net profits realized by limited partners.

Public Markets

        Through the Public Markets segment, we manage KKR Financial Holdings LLC, or KFN, which is a specialty finance company, as well as a number of investment funds, structured finance vehicles and separately managed accounts that invest capital in (i) leveraged credit strategies, such as leveraged

12

---

Table of Contents

loans and high yield bonds, (ii) liquid long/short equity strategies, (iii) alternative credit strategies such as mezzanine investments, special situations investments and direct senior lending and (iv) hedge funds solutions. Many of these funds, vehicles and accounts, including three management investment companies registered under the Investment Company Act of 1940 (the "1940 Act"), are managed by KKR Asset Management LLC, or KAM, an SEC registered investment adviser. On October 1, 2012 we acquired Prisma Capital Partners LP and its affiliates ("Prisma"), an SEC registered investment adviser, which manages our hedge fund solutions strategies. On January 23, 2013, we acquired a 24.9% interest in Nephila Capital Ltd. ("Nephila"), an investment manager focused on investing in natural catastrophe and weather risk. We intend to continue to grow the Public Markets business by leveraging our global investment platform, experienced investment professionals and the ability to adapt our investment strategies to different market conditions to capitalize on investment opportunities that may arise at every level of the capital structure and across market cycles.

        As of December 31, 2012, this segment had $26.4 billion of AUM, comprised of $10.9 billion of assets managed in our leveraged credit strategies, $3.8 billion of assets managed in our alternative credit strategies, $1.7 billion of assets managed across a range of strategies through KFN, $8.5 billion of assets managed in our hedge fund solutions strategies, $0.4 billion of assets managed in our liquid long/short equity strategies and $1.1 billion of assets managed in other strategies. Our alternative credit investments include $1.0 billion of assets managed in our mezzanine strategy, $2.4 billion of assets managed in our special situations strategy and $0.4 billion of assets managed in our direct lending strategy. The following chart presents the growth in the AUM of our Public Markets segment from the commencement of its operations in August 2004 through December 31, 2012.

Performance

        We generally review our performance in the Public Markets segment by investment strategy. Our leveraged credit strategies invest in leveraged loans and high yield bonds, or a combination of both. In certain cases these strategies have meaningful track records and may be compared to widely-known indices. The following chart presents information regarding these leveraged loan and high yield bond strategies from inception to December 31, 2012. Our other credit and equity strategies have begun investing more recently and therefore have not yet developed meaningful track records, and thus their performance is not included below. Past performance is no guarantee of future results.

Inception-to-Date Annualized Gross Performance vs. Benchmark(1) by Strategy

(1)

The Benchmarks referred to herein include the S&P/LSTA Leveraged Loan Index (the "S&P/LSTA Loan Index") and the Bank of America Merrill Lynch High Yield Master II Index (the "BoAML HY Master II Index" and, together with the S&P/LSTA Loan Index, the "Indices"). The S&P/LSTA Loan Index is an index that comprises all loans that meet the inclusion criteria and that have marks from the LSTA/LPC mark-to-market service. The inclusion criteria consist of the following: (i) syndicated term loan instruments consisting of term loans (both amortizing and institutional), acquisition loans (after they are drawn down) and bridge loans; (ii) secured; (iii) U.S. dollar denominated; (iv) minimum term of one year at inception; and (v) minimum initial spread of LIBOR plus 1.25%. The BoAML HY Master II Index is a market value weighted index of below investment grade U.S. dollar denominated corporate bonds publicly issued in the U.S. domestic market. "Yankee" bonds (debt of foreign issuers issued in the U.S. domestic market) are included in the BoAML HY Master II Index provided that the issuer is domiciled in a country having investment grade foreign currency long-term debt rating. Qualifying bonds must have maturities of one year or more, a fixed coupon schedule and minimum outstanding of US$100 million. In addition, issues having a credit rating lower than BBB3, but not in default, are also included. The indices do not reflect the reinvestment of income or dividends and the indices are not subject to management fees, incentive allocations or expenses. It is not possible to invest directly in unmanaged indices.

The Secured Credit Unlevered model performance track record is presented as supplemental information. The Secured Credit Unlevered model represents performance of KKR's Secured Credit Levered composite calculated on an unlevered basis. KKR's Secured Credit Levered composite has an investment objective that allows it to invest in assets other than senior secured

term loans and high yield securities, which includes asset backed securities, commercial mortgage backed securities, preferred stock, public equity, private equity and certain freestanding derivatives. In addition, KKR's Secured Credit Levered composite has employed leverage in its respective portfolios as part of its investment strategy. Gains realized with borrowed funds may cause returns to increase at a faster rate than would be the case without borrowings. If, however, investment results fail to cover the principal, interest and other costs of borrowings, returns could also decrease faster than if there had been no borrowings. Accordingly, the unlevered returns contained herein do not reflect the actual returns, and are not intended to be indicative of the future results of KKR's Secured Credit Levered composite. It is not expected that KKR's Secured Credit Levered composite will achieve comparable results. The Benchmark used for purposes of comparison for the Secured Credit strategy presented herein is the S&P/LSTA Loan Index. There are differences, in some cases, significant differences, between KKR's investments and the investments included in the Indices. For instance, KKR's composite may invest in securities that have a greater degree of risk and volatility, as well as liquidity risk, than those securities contained in the Indices.

(3)

Performance is based on a blended composite of Bank Loans Plus High Yield strategy accounts. The Benchmark used for purposes of comparison for the Bank Loans Plus High Yield strategy is based on 65% S&P/LSTA Loan Index and 35% ML HY Master II Index.

(4)

The Benchmark used for purposes of comparison for the High Yield carve-out strategy presented herein is based on the Bank of America Merrill Lynch High Yield Master II Index. The High Yield carve-out is comprised of all investments included in KKR-sponsored portfolios that have been identified as "below investment grade" or were rated "BB" or lower at time of issuance by Standard & Poor's. The collection of investments included in the High Yield carve-out come from various investment funds, vehicles and accounts sponsored by KKR.

Investment Approach

        Our approach to making investments focuses on creating investment portfolios that generate attractive risk-adjusted returns by selecting high-quality investments that may be made at attractive prices, applying rigorous standards of due diligence when making investment decisions, subjecting investments to regular monitoring and oversight, and, for more liquid investments, making buy and sell decisions based on price targets and relative value parameters. The firm employs both "top-down" and "bottom-up" analyses when making investments. Our top-down analysis involves a macro analysis of relative asset valuations, long-term industry trends, business cycles, regulatory trends, interest rate expectations, credit fundamentals and technical factors to target specific industry sectors and asset classes in which to invest. From a bottoms-up perspective, our investment decision is predicated on an investment thesis that is developed using our proprietary resources and knowledge. We will invest in a company only after it has undergone a due diligence analysis and the applicable investment committee has approved it.

Sourcing and Selecting Investments

        We source investment opportunities through a variety of channels, including internal deal generation strategies and the firm's global network of contacts at major companies, corporate executives, commercial and investment banks, financial intermediaries, other private equity sponsors and other investment and advisory institutions. We are also regularly provided with opportunities to invest, where appropriate, in the securities of KKR's private equity portfolio companies, though there are limitations by vehicle on the maximum size of such KKR-affiliated investments.

Table of Contents

Due Diligence and the Investment Decision

        Once a potential investment has been identified, our investment professionals screen the opportunity and make a preliminary determination concerning whether we should proceed with further diligence. When evaluating the suitability of an investment for our funds, we employ a relative value framework and subject the investment to a rigorous due diligence. This review considers, among other things, expected returns, capital structure, credit ratings, historical and projected financial data, the issuer's competitive position, the quality and track record of the issuer's management team, margin stability, and industry and company trends. Investment professionals use the services of outside advisors and industry experts as appropriate to assist them in the due diligence process and, when relevant and permitted, leverage the knowledge and experience of our private equity professionals. Strategy-specific investment committees monitor all due diligence practices and must approve an investment before it may be made.

Monitoring Investments

        We monitor our portfolios of investments using, as applicable, daily, quarterly and annual analyses. Daily analyses include morning market meetings, industry and company pricing runs, industry and company reports and discussions with the firm's private equity investment professionals on an as-needed basis. Quarterly analyses include the preparation of quarterly operating results, reconciliations of actual results to projections and updates to financial models (baseline and stress cases). Annual analyses involve conducting internal audits, and testing compliance with monitoring and documentation requirements.

Public Markets Strategies and Vehicles

KFN

        KKR Financial Holdings LLC (NYSE: KFN), or KFN, is an NYSE-listed specialty finance company that commenced operations in July 2004. Its majority-owned subsidiaries finance and invest in financial assets, including below investment grade corporate debt, marketable equity securities and private equity. Additionally, KFN has and may make additional investments in other asset classes including natural resources and real estate. Below investment grade debt includes senior secured and unsecured loans, mezzanine loans, high yield bonds, and distressed and stressed debt. We serve as the external manager of KFN under a management agreement and are entitled to receive a management fee and an incentive fee.

Credit Strategies

        Our credit strategies business pursues investments in debt securities ranging from liquid securities such as leveraged loans and high-yield bonds to alternative credit including longer-duration strategies such as mezzanine and special situations. These investments may be made across a range of vehicles including funds and single- or cross-strategy separately managed accounts. These managed accounts enable us to tailor an investment program to meet the specific risk, return and investment objective of individual institutional investors in our funds and vehicles.

        Leveraged Credit.    Our leveraged credit strategies are directed at investing in leveraged loans, high-yield bonds, or a combination of both. They are pursued primarily through separately managed accounts and registered investment companies, with a smaller amount of capital residing in funds. We are entitled to receive a fee for managing these vehicles.

        Structured Credit Vehicles.    Beginning in 2005, we began managing structured credit vehicles in the form of collateralized loan obligation transactions, or CLOs. CLOs are typically structured as bankruptcy-remote, special purpose investment vehicles which acquire, monitor and, to varying degrees, manage a pool of fixed income assets. KFN conducts a majority of its business through its

16

---

Table of Contents

holdings of a majority of the voting securities of, and certain other interests in, such CLOs. The CLOs serve as long term financing for fixed income investments and as a way to minimize refinancing risk, minimize maturity risk and secure a fixed cost of funds over an underlying market interest rate for KFN and other fixed income funds. We may receive a fee for managing certain CLOs.

        Alternative Credit.    In the last several years, our Public Markets business has expanded to include adjacent investment strategies in alternative credit which leverage the knowledge and relationships developed in the leveraged credit business. These strategies include mezzanine, distressed or special situations investing, and direct lending. As with our leveraged credit strategy, these are pursued through a combination of separately managed accounts, a registered investment company and funds. For managing these accounts and funds, we are entitled to receive either fees or a combination of fees and carried interest.

        Mezzanine.     We manage mezzanine investments primarily through a fund that invests in directly sourced third-party mezzanine transactions. These investments often consist of mezzanine debt, which generates a current yield, coupled with marginal equity exposure with additional upside potential. We closed our first dedicated mezzanine fund in August 2011. As of December 31, 2012, we had received $987.0 million of capital commitments to our Mezzanine strategy.

        Special Situations.     We seek to make opportunistic investments largely in distressed companies through our special situations investment strategy. These investments include secondary market distressed (including post-restructuring equity), control-oriented opportunities, rescue financing (debt or equity investments made to address covenant, maturity or liquidity issues), debtor-in-possession or exit financing, structured principal investments, and other event-driven investments in debt or equity. This strategy is primarily managed through separately managed accounts. As of December 31, 2012, we had received $2,189.3 million of capital commitments to our Special Situations strategy.

        Direct Lending.     We manage investments in proprietarily sourced senior debt financings for middle-market companies through our direct lending strategy. As of December 31, 2012, we had received $668.5 million of capital commitments to our Direct Lending strategy.

Equity Strategies

        We manage fundamental long/short equity investments in mid- and large-cap companies. The business was started in 2011 when we hired a team of experienced public equity investment executives. As of December 31, 2012, we had AUM of $0.4 billion in this strategy.

Retail Products

        Three funds in our leveraged credit strategy and alternative credit strategy, respectively, are registered under the 1940 Act as management investment companies. These funds and KKR Asset Management LLC, which serves as their investment adviser, are subject to the 1940 Act and the rules thereunder. The management fees we receive from these registered investment companies are generally paid on a regular basis (typically monthly) and proportionately increase or decrease based on the net asset value or gross assets of the investment company. The management fees we are paid for managing these investment companies will generally be subject to contractual rights that their board of directors (or, in the case of the business development company we manage, the investment adviser) has to terminate our investment management services with prior notice.

Hedge Fund Solutions

        In October 2012 we expanded our Public Markets business with the acquisition of Prisma, through which we provide customized hedge fund solutions. Hedge fund solutions involve the management of

17

Table of Contents

funds of hedge funds and other funds that allocate assets to third-party investment advisors and the funds and accounts they manage. Prisma's investment professionals who are organized by hedge fund strategy, work with risk and operational teams in conducting due diligence on portfolio managers. For the period beginning in June 2004 through December 31, 2012, Prisma's low volatility composite, consisting of all fee paying, fully discretionary accounts that it manages using a low volatility strategy, generated a net annualized return of 6.14%. As of December 31, 2012, Prisma managed $8.5 billion of AUM.

        The table below presents information as of December 31, 2012 relating to our Public Markets Vehicles.

Capital Markets and Principal Activities

        Our Capital Markets and Principal Activities segment combines KKR's principal assets with our global capital markets business. Our capital markets business, which includes 30 executives, supports our firm, our portfolio companies and select third-party clients by providing tailored capital markets advice and by developing and implementing both traditional and non-traditional capital solutions for

18

Table of Contents

investments and companies seeking financing. Our capital markets services include arranging debt and equity financing for transactions, placing and underwriting securities offerings, structuring new investment products and providing capital markets services. When our capital markets business underwrites an offering of securities or a loan, it commits to buy and sell an issue of securities or principal amount of indebtedness, and earns fees by purchasing those securities or indebtedness at a discount. In a syndication, this business earns a fee for arranging transactions and placing securities or indebtedness. To allow us to carry out these activities, we are registered or authorized to carry out certain broker dealer activities in various countries in North America, Europe, Asia-Pacific and the Middle East.

        In addition, through MerchCap Solutions LLC (formerly known as KKR-SPC Merchant Advisors LLC), we seek to provide certain capital markets services to mid-market and sponsor-backed companies as well as principal investments to support client needs.

        KKR's principal assets, which include investments in our investment funds and co-investments in certain portfolio companies of such funds, provide us with a significant source of capital to further grow and expand our business, increase our participation in our existing portfolio of businesses and further align our interests with those of our fund investors and other stakeholders. The large majority of principal assets consist of assets we acquired in the KPE Transaction. We believe that the market experience and skills of professionals in our capital markets business and the investment expertise of professionals in our Private Markets and Public Markets segments will allow us to continue to grow and diversify this asset base over time.

        As of December 31, 2012, the segment had $4.8 billion of investments at fair value. The following charts present information concerning our principal assets by type and geography as of December 31, 2012.

Client & Partner Group

        We have a Client & Partner Group that is responsible for raising capital for us globally across all products, expanding our client relationships across asset classes and across types of fund investors, developing products to meet our clients' needs, and servicing existing fund investors and products. As of December 31, 2012, we had 76 executives and professionals dedicated to our Client & Partner Group.

Competition

        We compete with other investment managers for both fund investors and investment opportunities. The firm's competitors consist primarily of sponsors of public and private investment funds, business development companies, investment banks, commercial finance companies and operating companies acting as strategic buyers. We believe that competition for fund investors is based primarily on investment performance, investor liquidity and willingness to invest, investor perception of investment managers' drive, focus and alignment of interest, business reputation, duration of relationships, quality of services, pricing, fund terms including fees, and the relative attractiveness of the types of investments that have been or are to be made. We believe that competition for investment opportunities is based primarily on the pricing, terms and structure of a proposed investment and certainty of execution. In addition to these traditional competitors within the global investment management industry, we also face competition from local and regional firms, financial institutions and sovereign wealth funds, in the various countries in which we invest. In certain emerging markets, local firms may have more established relationships with the companies in which we are attempting to invest. These competitors often fall into one of the aforementioned categories but in some cases may represent new types of fund investors, including high net worth individuals, family offices and state-sponsored entities.

        Over the past several years, the number of private equity funds and funds focused on natural resources, infrastructure, credit, equity and hedge fund strategies have continued to increase, heightening the level of competition for investor capital. Fund managers have also increasingly adopted investment strategies outside of their traditional focus. For example, funds focused on credit and equity strategies have become active in taking control positions in companies, while private equity funds have acquired minority and/or debt positions in publicly listed companies. This convergence could heighten competition for investments. Furthermore, as institutional fund investors increasingly consolidate their relationships for multiple investment products with a few investment firms, competition for capital from such institutional fund investors may become more acute.

        Some of the entities that we compete with as an investment firm may have greater financial, technical, marketing and other resources and more personnel than us and, in the case of some asset classes, longer operating histories, more established relationships or greater experience. Several of our competitors also have raised, or may raise, significant amounts of capital and have investment objectives that are similar to the investment objectives of our funds, which may create additional competition for investment opportunities. Some of these competitors may also have lower costs of

20

---

Table of Contents

capital and access to funding sources that are not available to us, which may create competitive advantages for them. In addition, some of these competitors may have higher risk tolerances, different risk assessments or lower return thresholds, which could allow them to consider a wider range of investments and to bid more aggressively than us for investments. Strategic buyers may also be able to achieve synergistic cost savings or revenue enhancements with respect to a targeted portfolio company, which may provide them with a competitive advantage in bidding for such investments.

        We expect to compete as a capital markets business primarily with investment banks and independent broker-dealers in the North America, Europe, Asia-Pacific and the Middle East. We principally focus our capital markets activities on the firm, our portfolio companies and fund investors, but we also seek to service other third parties, principally through MerchCap Solutions LLC. While we generally target customers with whom we have existing relationships, those customers may have similar relationships with the firm's competitors, many of whom will have access to competing securities transactions, greater financial, technical or marketing resources or more established reputations than us. The limited operating history of our capital markets business could make it difficult for us to compete with established investment banks or broker-dealers, participate in capital markets transactions of issuers or successfully grow the firm's capital markets business over time.

        Competition is also intense for the attraction and retention of qualified employees and consultants. Our ability to continue to compete effectively in our businesses will depend upon our ability to attract new employees and consultants and retain and motivate our existing employees and consultants.

Employees, Consultants and Advisors

        As of December 31, 2012, we employed or retained the services of over 1,000 people worldwide:

Investment Professionals

        Our 245 investment professionals come from diverse backgrounds in private equity, natural resources, infrastructure, real estate, fixed income, equities, hedge funds and other investment assets and include executives with operations, strategic consulting, risk management, liability management and finance experience. As a group, these professionals provide us with a strong global team for identifying attractive investment opportunities, creating value, and generating superior returns.

Other Professionals

        Our 400 other professionals come from diverse backgrounds in capital markets, capital raising, client servicing, public affairs, finance, tax, legal, human resources, and information technology. As a group, these professionals provide us with a strong team for overseeing investments and performing capital markets activities, servicing our existing fund investors and creating relationships with new fund investors globally. Additionally, a majority of these other professionals are responsible for supporting the global infrastructure of KKR.

KKR Capstone

        We have developed an institutionalized process for creating value in investments. As part of our effort, we utilize a team of 56 operating consultants at KKR Capstone, who work exclusively with our investment professionals and portfolio company management teams. With executives in North America, Europe and the Asia-Pacific, KKR Capstone provides additional expertise for assessing investment opportunities and assisting managers of portfolio companies in defining strategic priorities and implementing operational changes. During the initial phases of an investment, KKR Capstone's work seeks to implement our thesis for value creation. Our operating consultants may assist portfolio companies in addressing top-line growth, cost optimization and efficient capital allocation and in developing operating and financial metrics. Over time, this work shifts to identifying challenges and taking advantage of business opportunities that arise during the life of an investment.

Senior Advisors

        To complement the expertise of our investment professionals, we have a team of 32 senior advisors to provide us with additional operational and strategic insights. The responsibilities of senior advisors include serving on the boards of our portfolio companies, helping us evaluate individual investment opportunities and assisting portfolio companies with operational matters. These individuals include former chief executive officers, chief financial officers and chairmen of Fortune 500 companies, as well as other individuals who have held leading positions in major corporations and public agencies worldwide.

Organizational Structure

        The following simplified diagram illustrates our organizational structure as of December 31, 2012, unless otherwise noted. Certain entities depicted below may be held through intervening entities not shown in the diagram.

KKR Management LLC serves as the general partner of KKR & Co. L.P., which is governed by a Board of Directors consisting of a majority of independent directors. KKR Management LLC does not hold any economic interests in KKR & Co. L.P. and is owned by senior KKR principals.

KKR Holdings is the holding vehicle through which our principals indirectly own their interest in KKR. KKR Group Partnership Units that are held by KKR Holdings are exchangeable for our common units on a one-for-one basis, subject to customary conversion rate adjustments for splits, unit distributions and reclassifications and compliance with applicable vesting and transfer restrictions. As limited partner interests, these KKR Group Partnership Units are non-voting and do not entitle KKR Holdings to participate in the management of our business and affairs. As of December 31, 2012, KKR Holdings had a 63.1% interest in our business indirectly through its limited partner interests in the KKR Group Partnerships.

KKR Holdings holds special non-economic voting units in our partnership that entitle it to cast, with respect to those limited matters that may be submitted to a vote of our unitholders, a number of votes equal to the number of KKR Group Partnership Units that it holds from time to time.

KKR Group Finance Co. LLC is a wholly-owned subsidiary of KKR Management Holdings Corp. and the issuer of our $500 million aggregate principal amount of 6.375% Senior Notes due 2020 (the "2020 Senior Notes"). The 2020 Senior Notes are guaranteed by KKR & Co. L.P. and the KKR Group Partnerships.

KKR Group Finance Co. II LLC is a wholly-owned subsidiary of KKR Management Holdings Corp. and the issuer of our $500 million aggregate principal amount of 5.500% Senior Notes due 2043 (the "2043 Senior Notes"), which were issued on February 1, 2013. The 2043 Senior Notes are guaranteed by KKR & Co. L.P. and the KKR Group Partnerships.

Because the income of KKR Management Holdings L.P. is likely to be primarily non-qualifying income for purposes of the qualifying income exception to the publicly traded partnership rules, we formed KKR Management Holdings Corp., which is subject to taxation as a corporation for U.S. federal income tax purposes, to hold our KKR Group Partnership Units in KKR Management Holdings L.P. Accordingly, our allocable share of the taxable income of KKR Management Holdings L.P. will be subject to taxation at a corporate rate. KKR Management Holdings L.P., which is treated as a partnership for U.S. federal income tax purposes, was formed to hold interests in our fee generating businesses and other assets that may not generate qualifying income for purposes of the qualifying income exception to the publicly traded partnership rules. KKR Fund Holdings L.P., which is also treated as a partnership for U.S. federal income tax purposes, was formed to hold interests in our businesses and assets that will generate qualifying income for purposes of the qualifying income exception to the publicly traded partnership rules.

Regulation

        Our operations are subject to regulation and supervision in a number of jurisdictions.

regulatory and legal requirements that apply to our activities are subject to change from time to time and may become more restrictive, which may make compliance with applicable requirements more difficult or expensive or otherwise restrict our ability to conduct our business activities in the manner in which they are now conducted. Changes in applicable regulatory and legal requirements, including changes in their enforcement, could materially and adversely affect our business and our financial condition and results of operations. As a matter of public policy, the regulatory bodies that regulate our business activities are generally responsible for safeguarding the integrity of the securities and financial markets and protecting fund investors who participate in those markets rather than protecting the interests of our unitholders.

Regulation as an Investment Adviser

        We conduct our advisory business through our investment adviser subsidiaries, including Kohlberg Kravis Roberts & Co. L.P. and its wholly-owned subsidiaries KKR Asset Management LLC and Prisma Capital Partners LP, each of which is registered as an investment adviser with the SEC under the Investment Advisers Act. These investment advisers are subject to the anti-fraud provisions of the Investment Advisers Act and to fiduciary duties derived from these provisions which apply to our relationships with our advisory clients globally, including funds that we manage. These provisions and duties impose restrictions and obligations on us with respect to our dealings with our fund investors and our investments, including for example restrictions on agency cross and principal transactions. Our registered investment advisers are subject to periodic SEC examinations and other requirements under the Investment Advisers Act and related regulations primarily intended to benefit advisory clients. These additional requirements relate, among other things, to maintaining an effective and comprehensive compliance program, recordkeeping and reporting requirements and disclosure requirements. The Investment Advisers Act generally grants the SEC broad administrative powers, including the power to limit or restrict an investment adviser from conducting advisory activities in the event it fails to comply with federal securities laws. Additional sanctions that may be imposed for failure to comply with applicable requirements include the prohibition of individuals from associating with an investment adviser, the revocation of registrations and other censures and fines.

        KKR Asset Management is subject to regulation under the 1940 Act as an investment adviser to registered investment companies. KKR Alternative Corporate Opportunities Fund and KKR Alternative Corporate Opportunities Fund P are closed-end management investment companies (a master fund and a feeder fund, respectively), and KKR Series Trust is an open-end management investment company, registered under the 1940 Act. The open-end management investment company, the closed-end management companies and KKR Asset Management are subject to the 1940 Act and the rules thereunder, which among other things regulate the relationship between a registered investment company and its investment adviser and prohibit or severely restrict principal transactions and joint transactions.

ITEM 1A.    RISK FACTORS

        Investing in our securities involves risk. Persons investing in our securities should carefully consider the risks described below and the other information contained in this report and other filings that we make from time to time with the SEC, including our consolidated and combined financial statements and accompanying notes. Any of the following risks could materially and adversely affect our business, financial condition or results of operations. Our business, financial condition or results of operations could also be adversely affected by additional factors that apply to all companies generally, as well as other risks that are not currently known to us or that we currently view to be immaterial. In any such case, the trading price of our securities could decline and you may lose all or part of your original investment. While we attempt to mitigate known risks to the extent we believe to be practicable and reasonable, we can provide no assurance, and we make no representation, that our mitigation efforts will be successful.

Risks Related to Our Business

Difficult market conditions can adversely affect our business in many ways, including by reducing the value or performance of the investments that we manage or by reducing the ability of our funds to raise or deploy capital, each of which could negatively impact our net income and cash flow and adversely affect our financial condition.

        Our business is materially affected by conditions in the financial markets and economic conditions or events throughout the world, such as interest rates, availability of credit, inflation rates, economic uncertainty, changes in laws (including laws relating to taxation), trade barriers, commodity prices, currency exchange rates and controls and national and international political circumstances (including wars, terrorist acts or security operations). For example, the unprecedented turmoil in the global financial markets during 2008 and 2009 provoked significant volatility of securities prices, contraction in the availability of credit and the failure of a number of companies, including leading financing institutions, and had a material adverse effect on our businesses. While the adverse effects of that period have abated to a degree, economic weakness has continued, characterized by low levels of growth and high levels of unemployment and governmental deficits in major markets including the

27

Table of Contents

United States and Europe. In addition, global financial markets have experienced significant volatility following the downgrade by Standard & Poor's on August 5, 2011 of the long-term credit rating of U.S. Treasury debt from AAA to AA+. Furthermore while a number of policy actions have been implemented with respect to debt and banks in a number of European countries, Europe continues to experience negative growth and ongoing austerity. Deleveraging in the developed world is continuing and likely to persist in the near-term. Furthermore, while U.S. financial institutions have seen recent improvements, global financial institutions have generally not yet provided debt financing in amounts and on terms commensurate with what they provided prior to 2008.

        Such market and economic conditions are outside our control and may affect the level and volatility of securities prices and the liquidity and the value of our investments. In addition, we may not be able to or may choose not to manage our exposure to these conditions and/or events. For example, as of March 31, 2009, the date of the lowest aggregate valuation of our private equity funds during the most recent downturn, the investments in our contributed private equity funds were marked down to 67% of original cost. Our profitability may also be adversely affected by our fixed costs and the possibility that we would be unable to scale back other costs within a time frame sufficient to match any decreases in net income relating to changes in market and economic conditions.

        Unfavorable market conditions may reduce opportunities for our funds to make, exit and realize value from their investments. For example, when financing is not available, it is difficult for potential buyers to raise sufficient capital to purchase assets in our funds' portfolios. Consequently, we may earn lower than expected returns on investments, which could cause us to realize diminished or no carried interest. In addition, we may not be able to find suitable investments for the funds to effectively deploy capital, which could adversely affect our ability to raise new funds because we can generally only raise capital for a successor fund following the substantial deployment of capital from the existing fund. In the event of poor performance by existing funds or during periods of unfavorable fundraising conditions, as have prevailed in recent years, pressures by fund investors for lower fees, different fee sharing arrangements for transaction or other fees, and other concessions (for example, the inclusion of performance hurdles that will require us in our newer funds, such as North America Fund XI and Asian Fund II, to generate a specified return on investment prior to our right to receive carried interest) will likely continue and could increase. The outcome of such negotiations could result in our agreement to terms that are materially less favorable to us than for prior funds we have managed. In the circumstances described above, successor funds raised by us are also likely in many instances to be smaller than our comparable predecessor funds. Fund investors may also seek to redeploy capital away from certain of our fixed income or other non-private equity investment vehicles, which permit redemptions on relatively short notice, in order to meet liquidity needs or invest in other asset classes. Any of these developments could adversely affect our future revenues, net income, cash flow, financial condition or ability to retain our employees. See "—Our inability to raise additional or successor funds could have a material adverse impact on our business" and "—Our investors in future funds may negotiate to pay us lower management fees and the economic terms of our future funds may be less favorable to us than those of our existing funds, which could adversely affect our revenues."

        During periods of difficult market or economic conditions or slowdowns (which may be across one or more industries, sectors or geographies), companies in which we have invested may experience decreased revenues, financial losses, credit rating downgrades, difficulty in obtaining access to financing and increased funding costs. These companies may also have difficulty in expanding their businesses and operations or be unable to meet their debt service obligations or other expenses as they become due, including amounts payable to us. Negative financial results in our funds' portfolio companies may result in lower investment returns for our investment funds, which could materially and adversely affect our operating results and cash flow. To the extent the operating performance of such portfolio companies (as well as valuation multiples) deteriorate or do not improve, our funds may sell those assets at values that are less than we projected or even at a loss, thereby significantly affecting those funds' performance and consequently our operating results and cash flow. During periods of economic difficulty, our investment funds' portfolio companies may also have difficulty expanding their businesses

28

and operations or meeting their debt service obligations or other expenses as they become due, including amounts payable to us. Furthermore, negative market conditions or a specific market dislocation may result in lower investment returns for our funds, which would further adversely affect our net income. Adverse conditions may also increase the risk of default with respect to private equity, fixed income and other equity investments that we manage. Even if economic and market conditions do improve broadly, adverse conditions in particular sectors may also cause our performance to suffer. Finally, low interest rates related to monetary stimulus and economic stagnation may negatively impact expected returns on all types of investments as the demand for relatively higher return assets increases and the supply decreases.

Changes in the debt financing markets may negatively impact the ability of our investment funds and their portfolio companies to obtain attractive financing for their investments and may increase the cost of such financing if it is obtained, which could lead to lower-yielding investments and potentially decrease our net income.

        In the event that our funds are unable to obtain committed debt financing for potential acquisitions or can only obtain debt at an increased interest rate or on unfavorable terms, our funds may have difficulty completing otherwise profitable acquisitions or may generate profits that are lower than would otherwise be the case, either of which could lead to a decrease in the investment income earned by us. Any failure by lenders to provide previously committed financing can also expose us to potential claims by sellers of businesses which we may have contracted to purchase. Similarly, our portfolio companies regularly utilize the corporate debt markets in order to obtain financing for their operations. To the extent that credit markets render such financing difficult to obtain or more expensive, this may negatively impact the operating performance of those portfolio companies and, therefore, the investment returns on our funds. In addition, to the extent that the markets make it difficult or impossible to refinance debt that is maturing in the near term, we or some of our portfolio companies may be unable to repay such debt at maturity and may be forced to sell assets, undergo a recapitalization or seek bankruptcy protection. In addition, to the extent that conditions in the credit markets impair the ability of our portfolio companies to refinance or extend maturities on their outstanding debt, either on favorable terms or at all, the operating performance of those portfolio companies may be negatively impacted, which could impair the value of our investment in those portfolio companies and lead to a decrease in the investment income earned by us. In some cases, the inability of our portfolio companies to refinance or extend maturities may result in the inability of those companies to repay debt at maturity and may cause the companies to sell assets, undergo a recapitalization or seek bankruptcy protection, which would also likely impair the value of our investment and lead to a decrease in investment income earned by us.

Adverse economic and market conditions may adversely affect our liquidity position, which could adversely affect our business operations in the future.

        We expect that our primary liquidity needs will consist of cash required to:

•

continue to grow our business, including seeding new strategies and funding our capital commitments made to existing and future funds, co-investments and any net capital requirements of our capital markets companies;



•

service debt obligations, as well as any contingent liabilities that may give rise to future cash payments;



•

fund cash operating expenses;



•

pay amounts that may become due under our tax receivable agreement with KKR Holdings;

29

---

Table of Contents

•

make cash distributions in accordance with our distribution policy;



•

underwrite commitments within our capital markets business; and



•

acquire additional principal assets, including other investment advisory and broker-dealer businesses.

        These liquidity requirements are significant and, in some cases, involve capital that will remain invested for extended periods of time. As of December 31, 2012, we have approximately $677.9 million of remaining unfunded capital commitments to our investment funds. Our commitments to our funds will require significant cash outlays over time, and there can be no assurance that we will be able to generate sufficient cash flows from realizations of investments to fund them. In addition, as of December 31, 2012, we had $500.0 million of borrowings outstanding under our credit facilities and debt securities and $1,534.3 million of cash and short-term investments, which does not include $500 million of senior notes issued on February 1, 2013. While we have long-term committed financings with substantial facility limits, the terms of those facilities will expire in 2016 and 2017 and our senior notes become due in 2020 and 2043 (see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity"), and any borrowings thereunder will require refinancing or renewal, which could result in higher borrowing costs, or issuing equity. Depending on credit market conditions, we may not be able to renew all or part of these borrowings or find alternate sources of financing on commercially reasonable terms or raise equity. In addition, the underwriting commitments for our capital markets business may require significant cash obligations, and these commitments may also put pressure on our liquidity. The holding company for our capital markets business has entered into a credit agreement that provides for revolving borrowings of up to $500 million, which can be used in connection with our capital markets business, including placing and underwriting securities offerings. To the extent we commit to buy and sell an issue of securities in firm commitment underwritings or otherwise, we may be required to borrow under our credit agreement for our capital markets business to fund such obligations, which, depending on the size and timing of the obligations, may limit our ability to enter into other underwriting arrangements or similar activities, service existing debt obligations or otherwise grow our business. Regulatory capital requirements may also limit the ability of our broker-dealer subsidiaries to participate in underwriting or other transactions or to allocate our capital more efficiently across our businesses. In addition, in connection with our acquisitions of Prisma and a minority interest in Nephila, we may be obligated to make future deferred purchase price payments based on the respective performance of these businesses. In the event that our liquidity requirements were to exceed available liquid assets for the reasons specified above or for any other reason, we could be forced to sell assets or seek to raise debt or equity capital on unfavorable terms.

The "clawback" or "net loss sharing" provisions in our governing agreements may give rise to a contingent obligation that may require us to return or contribute amounts to our funds and fund investors.

        The partnership documents governing our carry paying funds, including funds and vehicles relating to private equity, mezzanine, infrastructure and special situations investments, generally include a "clawback" provision that, if triggered, may give rise to a contingent obligation requiring the general partner to return or contribute amounts to the fund for distribution to investors at the end of the life of the fund. Under a clawback obligation, upon the liquidation of a fund, the general partner is required to return, typically on an after-tax basis, previously distributed carry to the extent that, due to the diminished performance of later investments, the aggregate amount of carry distributions received by the general partner during the term of the fund exceed the amount to which the general partner was ultimately entitled, including the effects of any performance hurdles. Excluding carried interest received by the general partners of funds that were not contributed to us in the KPE Transaction, as of December 31, 2012, no carried interest was subject to this clawback obligation, assuming that all applicable carry paying funds were liquidated at their December 31, 2012 fair values. Had the

30

---

Table of Contents

investments in such funds been liquidated at zero value, the clawback obligation would have been $1,095.4 million.

        Certain private equity funds that were contributed to us in the KPE Transaction also include a "net loss sharing provision." Upon the liquidation of an investment vehicle to which a net loss sharing obligation applies, the general partner is required to contribute capital to the vehicle to fund 20% of the net losses on investments. In these vehicles, such losses would be required to be paid by us to the limited partners in those vehicles in the event of a liquidation of the fund regardless of whether any carried interest had previously been distributed, and a greater share of the investment losses would be allocable to us relative to the capital that we contributed to it as the general partner. Based on the fair market values as of December 31, 2012, there would have been no net loss sharing obligation. If these net loss sharing vehicles were liquidated at zero value, the net loss sharing obligation as of December 31, 2012 would have been approximately $616.7 million.

        Prior to the KPE Transaction, certain of our principals who received carried interest distributions with respect to certain private equity funds contributed to us had personally guaranteed, on a several basis and subject to a cap, the contingent obligations of the general partners of such private equity funds to repay amounts to fund limited partners pursuant to the general partners' clawback obligations. The terms of the KPE Transaction require that our principals remain responsible for clawback obligations relating to carry distributions received prior to the KPE Transaction up to a maximum of $223.6 million. Carry distributions arising subsequent to the KPE Transaction may give rise to clawback obligations that may be allocated generally to us and to our principals who participate in the carry pool. Unlike the clawback obligation, we will be responsible for amounts due under a net loss sharing obligation and will indemnify our principals for any personal guarantees that they have provided with respect to such amounts. In addition, guarantees of or similar arrangements relating to, clawback or net loss sharing obligations in favor of third party investors in an individual investment partnership by entities we own may limit distributions of carried interest more generally.

Our earnings and cash flow are highly variable due to the nature of our business and we do not intend to provide earnings guidance, each of which may cause the value of interests in our business to be volatile.

        Our earnings are highly variable from quarter to quarter due to the volatility of investment returns of most of our funds and other investment vehicles and our principal assets and the fees earned from our businesses. We recognize earnings on investments in our funds based on our allocable share of realized and unrealized gains (or losses) reported by such funds and for certain of our recent funds, when a performance hurdle is achieved. A decline in realized or unrealized gains, a failure to achieve a performance hurdle or an increase in realized or unrealized losses, would adversely affect our net income. Fee income, which we recognize when contractually earned, can vary due to fluctuations in AUM, the number of investment transactions made by our funds, the number of portfolio companies we manage, the fee provisions contained in our funds and other investment products and transactions by our capital markets business. Fees for the years ended December 31, 2010, 2011 and 2012 were $435.4 million, $723.6 million and $568.4 million, respectively. We may create new funds or investment products or vary the terms of our funds or investment products, which may alter the composition or mix of our income from time to time. We may also experience fluctuations in our results from quarter to quarter, including our revenue and net income, due to a number of other factors, including changes in the values of our funds' investments, changes in the amount of distributions or interest earned in respect of investments, changes in our operating expenses, the degree to which we encounter competition and general economic and market conditions. Net income (loss) attributable to KKR & Co. L.P. for the years ended December 31, 2010, 2011 and 2012 was $333.2 million, $1.9 million and $560.8 million, respectively. Such fluctuations may lead to variability in the value of interests in our business and cause our results for a particular period not to be indicative of our performance in future periods. It may be difficult for us to achieve steady growth in net income and

31

Table of Contents

cash flow on a quarterly basis, which could in turn lead to large adverse movements in the value of interests in our business.

        The timing and receipt of carried interest from our investment funds are unpredictable and will contribute to the volatility of our cash flows. For example, carried interest on our private equity funds is generally distributed to the general partner of a vehicle with a clawback or net loss sharing provision only after all of the following are met: (i) a realization event has occurred (e.g., sale of a portfolio company, dividend, etc.); (ii) the vehicle has achieved positive overall investment returns on realized investments since its inception, in excess of a performance hurdle, where applicable; and (iii) with respect to investments with a fair value below cost, cost has been returned to fund investors in an amount sufficient to reduce remaining cost to the investments' fair value. Carried interest payments from investments depend on our funds' performance and opportunities for realizing gains, which may be limited. It takes a substantial period of time to identify attractive investment opportunities, to raise all the funds needed to make an investment and then to realize the cash value (or other proceeds) of an investment through a sale, public offering or other exit. To the extent an investment is not profitable, no carried interest shall be received from our funds with respect to that investment and, to the extent such investment remains unprofitable, we will only be entitled to a management fee on that investment. Furthermore, certain vehicles and separately managed accounts may not provide for the payment of carry at all. Even if an investment proves to be profitable, it may be several years before any profits can be realized in cash. We cannot predict when, or if, any realization of investments will occur. In addition, if finance providers, such as commercial and investment banks, make it difficult for potential purchasers to secure financing to purchase companies in our investment funds' portfolio, it may decrease potential realization events and the potential to earn carried interest. A downturn in the equity markets would also make it more difficult to exit investments by selling equity securities. If we were to have a realization event in a particular quarter, the event may have a significant impact on our cash flows during the quarter that may not be replicated in subsequent quarters. A decline in realized or unrealized gains, or an increase in realized or unrealized losses, would adversely affect our investment income, which could further increase the volatility of our quarterly results.

        In addition, with respect to certain of the funds and vehicles that we advise, such as hedge funds, fund of funds and KFN, we are entitled to incentive fees that are generally paid annually, semi-annually or quarterly if the net asset value of a fund has increased over a certain pre-determined hurdle rate or a specified high-water mark. These funds, but not KFN, also have "high-water mark" provisions whereby if the funds have experienced losses in prior periods, we will not be able to earn incentive fees with respect to an fund investor's account until the net asset value of the fund investor's account exceeds the highest period end value on which incentive fees were previously paid. The incentive fees we earn are therefore dependent on the net asset value of these funds or vehicles, which could lead to volatility in our quarterly results and cash flow.

        The timing and receipt of carried interest also varies with the life cycle of our funds. Our carry paying funds that are in harvesting periods when they are making realization events for mature investments are more likely to make larger distributions than our carrying paying funds that are in their fund raising or investment periods that precede the harvesting period. During times when a significant portion of our assets under management is attributable to carry paying funds that are not in their harvesting periods, we may receive substantially lower carried interest distributions.

A decline in the pace or size of investment by our funds or an increase in the amount of transaction fees we share with our fund investors would result in our receiving less revenue from transaction fees.

        The transaction fees that we earn are driven in part by the pace at which our funds make investments and the size of those investments. Any decline in that pace or the size of such investments

would reduce our transaction fees and could make it more difficult for us to raise capital. Many factors could cause such a decline in the pace of investment, including:

•

the inability of our investment professionals to identify attractive investment opportunities;



•

competition for such opportunities among other potential acquirers;



•

decreased availability of capital or financing on attractive terms;



•

our failure to consummate identified investment opportunities because of business, regulatory or legal complexities and adverse developments in the U.S. or global economy or financial markets; and



•

terms we may provide to our fund investors to increase the percentage of transaction or other fees we may share with them.

Our inability to raise additional or successor funds (or raise successor funds of a comparable size as our predecessor funds) could have a material adverse impact on our business.

        Our current private equity funds and certain other funds and investment vehicles have a finite life and a finite amount of commitments from fund investors. Once a fund nears the end of its investment period, our success depends on our ability to raise additional or successor funds in order to keep making investments and, over the long term, earning management fees (although our funds and investment vehicles generally continue to earn management fees at a reduced fee rate after the expiration of their investment periods). Even if we are successful in raising successor funds, to the extent we are unable to raise successor funds of a comparable size to our predecessor funds, our revenues may decrease as the investment period of our predecessor funds expire and associated fees decrease. For example, the ultimate size of KKR North America Fund XI, our most recent private equity fund focused primarily on North America, will be smaller than its predecessor fund. The evolving preferences of our fund investors may necessitate that alternatives to the traditional investment fund structure, such as managed accounts, smaller funds and co-investment vehicles become a larger part of our business going forward. This could increase our cost of raising capital at the scale we have historically achieved. Furthermore, in order to raise capital for new strategies and products without drawing capital away from our existing products, we will need to seek new sources of capital. Institutional investors in funds that have suffered from decreasing returns, liquidity pressure, increased volatility or difficulty maintaining targeted asset allocations, may materially decrease or temporarily suspend making new fund investments. Such investors may elect to reduce their overall portfolio allocations to alternative investments such as private equity funds, resulting in a smaller overall pool of available capital in our industry. In addition, the asset allocation rules or regulations or investment policies to which such third-party investors are subject, could inhibit or restrict the ability of third-party investors to make investments in our investment funds. Coupled with a lack of distributions from their existing investment portfolios, many of these investors may have been left with disproportionately outsized remaining commitments to, and invested capital in, a number of investment funds, which significantly limited their ability to make new commitments to third-party managed investment funds such as those advised by us.

        Fund investors may also seek to redeploy capital away from certain of our fixed income vehicles, hedge fund, fund of funds or other investment vehicles, which permit redemptions on relatively short notice in order to meet liquidity needs or invest in other asset classes. We believe that our ability to avoid excessive redemption levels primarily depends on our funds' continued satisfactory performance, although redemptions may also be driven by other factors important to our fund investors, including their need for liquidity and compliance with investment mandates, even if our performance is superior. Any such redemptions would decrease our AUM and revenues.

        In addition, the "Volcker Rule" passed in connection with the Dodd-Frank Wall Street Reform and Consumer Protection Act is expected to severely limit or prohibit investments in private equity funds by U.S. banks (and in some cases non-U.S. banks) and could limit such investments by regulated insurance companies. Financial institutions have historically represented an important class of investors in our funds, including approximately 11% of our AUM as of December 31, 2012, and it is possible that other institutions will not be available to replace this traditional source of capital for our private equity funds. To the extent we are unable to raise additional or successor funds (or to raise successor funds of the same size as our predecessor funds), our AUM and revenues will likely decrease as the investment period of our predecessor funds expire and associated fees decrease.

Our investors in future funds, including separately managed accounts, may negotiate to pay us lower management fees and the economic terms of our future funds may be less favorable to us than those of our existing funds, which could adversely affect our revenues.

        In connection with raising new funds or securing additional investments in existing funds, we negotiate terms for such funds and investments with investors. The outcome of such negotiations could result in our agreement to terms that are materially less favorable to us than the terms of prior funds we have advised or funds advised by our competitors. For example such terms could restrict our ability to raise investment funds with investment objectives or strategies that compete with existing funds, reduce fee revenues we earn, reduce the percentage of profits on third-party capital in which we share, include a performance hurdle that requires us to generate a specified return on investment prior to our right to receive carried interest or add expenses and obligations for us in managing the fund or increase our potential liabilities. For example our newest private equity funds such as North America Fund XI and Asian Fund II include a performance hurdle that requires us to generate a 7% return on investment prior to receiving our share of fund gains. Furthermore, as institutional investors increasingly consolidate their relationships with investment firms and competition becomes more acute, we may receive more such requests to modify the terms in our new funds. Agreement to terms that are materially less favorable to us could result in a decrease in our profitability.

        Certain institutional investors have also publicly criticized certain fund fee and expense structures, including management fees and transaction and advisory fees. We have received and expect to continue to receive requests from a variety of fund investors and groups representing such investors to decrease fees and to modify our carried interest and incentive fee structures, which could result in a reduction or delay in the timing of receipt of the fees and carried interest and incentive fees we earn. In September of 2009, the Institutional Limited Partners Association, or "ILPA," published a set of Private Equity Principles, or the "Principles," which were revised in January 2011. The Principles were developed in order to encourage discussion between limited partners and general partners regarding private equity fund partnership terms. Certain of the Principles call for enhanced "alignment of interests" between general partners and limited partners through modifications of some of the terms of fund arrangements, including proposed guidelines for fees and carried interest structures. We provided ILPA our endorsement of the Principles, representing an indication of our general support for the efforts of ILPA.

        In addition, certain institutional investors, including sovereign wealth funds and public pension funds, have demonstrated an increased preference for alternatives to the traditional investment fund structure, such as managed accounts, specialized funds and co-investment vehicles. We also have entered into strategic partnerships with individual investors whereby we manage that investor's capital across a variety of our products on separately negotiated terms. There can be no assurance that such alternatives will be as profitable to us as the traditional investment fund structure, and the impact such a trend could have on our results of operations, if widely implemented, is unclear. Moreover, certain institutional investors are demonstrating a preference to in-source their own investment professionals

34

and to make direct investments in alternative assets without the assistance of private equity advisers like us. Such institutional investors may become our competitors and could cease to be our clients.

        Any agreement to terms less favorable to us could adversely affect our revenues and profitability.

The investment management business is intensely competitive, which could have a material adverse impact on our business.

        We compete as an investment manager for both fund investors and investment opportunities. The investment management business is highly fragmented, with our competitors consisting primarily of sponsors of public and private investment funds, business development companies, investment banks, commercial finance companies and operating companies acting as strategic buyers of businesses. We believe that competition for fund investors is based primarily on:

•

investment performance;



•

investor liquidity and willingness to invest;



•

investor perception of investment managers' drive, focus and alignment of interest;



•

business reputation;



•

the duration of relationships with fund investors;



•

the quality of services provided to fund investors;



•

pricing;



•

fund terms (including fees); and



•

the relative attractiveness of the types of investments that have been or will be made.

        We believe that competition for investment opportunities is based primarily on the pricing, terms and structure of a proposed investment and certainty of execution.

        A number of factors serve to increase our competitive risks:

•

a number of our competitors in some of our businesses may have greater financial, technical, marketing and other resources and more personnel than we do;



•

fund investors may materially decrease their allocations in new funds in light of their experiences following an economic downturn or seek to consolidate their relationships with investment firms;



•

some of our competitors may have better expertise or be regarded by fund investors as having better expertise in a specific asset class or geographic region than we do;



•

some of our competitors have agreed to terms on their investment funds or products that may be more favorable than our funds or products, such as lower management fees, greater fee sharing, or performance hurdles for carried interest, and therefore we may be forced to match or otherwise revise our terms to be less favorable than they have been in the past;



•

some of our funds may not perform as well as competitors' funds or other available investment products;



•

fund investors may reduce their investments in our funds or not make additional investments in our funds based upon their available capital or due to regulatory requirements;



•

our competitors have raised or may raise significant amounts of capital, and many of them have similar investment objectives and strategies to our funds, which may create additional competition for investment opportunities and may reduce the size and duration of pricing inefficiencies that many alternative investment strategies seek to exploit;

35

Table of Contents

•

some of these competitors may also have a lower cost of capital and access to funding sources that are not available to us, which may create competitive disadvantages for us with respect to investment opportunities;



•

some of our competitors may have higher risk tolerances, different risk assessments or lower return thresholds, which could allow them to consider a wider variety of investments and to bid more aggressively than us for investments;



•

some of our competitors may be subject to less regulation or less regulatory scrutiny and accordingly may have more flexibility to undertake and execute certain businesses or investments than we do and/or bear less expense to comply with such regulations than we do;



•

there are relatively few barriers to entry impeding the formation of new funds, including a relatively low cost of entering these businesses, and the successful efforts of new entrants into our various lines of business, including major commercial and investment banks and other financial institutions, have resulted in increased competition;



•

some fund investors may prefer to invest with an investment manager that is not publicly traded, is smaller, or manages fewer investment products; and



•

other industry participants will from time to time seek to recruit our investment professionals and other employees away from us.

        We may lose investment opportunities in the future if we do not match investment prices, structures and terms offered by competitors. Our competitors that are corporate buyers may be able to achieve synergistic cost savings in respect of an investment, which may provide them with a competitive advantage in bidding for an investment. Alternatively, we may experience decreased investment returns and increased risks of loss if we match investment prices, structures and terms offered by competitors. Moreover, if we are forced to compete with other investment firms on the basis of price, we may not be able to maintain our current fund fee, carried interest or other terms. There is a risk that fees and carried interest in the alternative investment management industry will decline, without regard to the historical performance of a manager. Fee or carried interest income reductions on existing or future funds, without corresponding decreases in our cost structure, would adversely affect our revenues and profitability.

        In addition, if interest rates were to rise or if market conditions for competing investment products become or are favorable and such products begin to offer rates of return superior to those achieved by our funds, the attractiveness of our funds relative to investments in other investment products could decrease. This competitive pressure could adversely affect our ability to make successful investments and limit our ability to raise future funds, either of which would adversely impact our business, results of operations and cash flow.

Our structure involves complex provisions of U.S. federal income tax laws for which no clear precedent or authority may be available. These structures also are subject to potential legislative, judicial or administrative change and differing interpretations, possibly on a retroactive basis.

        The U.S. federal income tax treatment of our unitholders depends in some instances on determinations of fact and interpretations of complex provisions of U.S. federal income tax laws for which no clear precedent or authority may be available. You should be aware that the U.S. federal income tax rules are constantly under review by persons involved in the legislative process, the Internal Revenue Service, or IRS, and the U.S. Department of the Treasury frequently resulting in revised interpretations of established concepts, statutory changes, revisions to regulations and other modifications and interpretations. The present U.S. federal income tax treatment of owning our common units may be modified by administrative, legislative or judicial interpretation at any time, and any such action may affect investments and commitments previously made. For instance, changes to the

36

Table of Contents

U.S. federal tax laws and interpretations thereof could make it more difficult or impossible for us to be treated as a partnership that is not taxable as a corporation for U.S. federal income tax purposes, affect the tax considerations of owning our common units, change the character or treatment of portions of our income (including, for instance, the treatment of carried interest as ordinary income rather than capital gain) and adversely impact your investment in our common units. See the discussion below under "—The U.S. Congress has considered legislation that would have (i) in some cases after a ten-year period, precluded us from qualifying as a partnership or required us to hold carried interest through taxable subsidiary corporations and (ii) taxed certain income and gains at increased rates. If any similar legislation were to be enacted and apply to us, the after tax income and gain related to our business, as well as the market price of our units, could be reduced." Our organizational documents and agreements give the Managing Partner broad authority to modify the amended and restated partnership agreement from time to time as the Managing Partner determines to be necessary or appropriate, without the consent of the unitholders, to address changes in U.S. federal, state and local income tax regulations, legislation or interpretation. In some circumstances, such revisions could have a material adverse impact on some or all unitholders. For instance, the Managing Partner could elect at some point to treat us as an association taxable as a corporation for U.S. federal (and applicable state) income tax purposes. If the Managing Partner were to do this, the U.S. federal income tax consequences of owning our common units would be materially different. Moreover, certain assumptions and conventions will be applied in an attempt to comply with applicable rules and to report income, gain, deduction, loss and credit to unitholders in a manner that reflects such unitholders' beneficial ownership of partnership items, taking into account variation in ownership interests during each taxable year because of trading activity. However, those assumptions and conventions may not be in compliance with all aspects of applicable tax requirements. It is possible that the IRS will assert successfully that the conventions and assumptions used by us do not satisfy the technical requirements of the Internal Revenue Code and/or Treasury regulations and could require that items of income, gain, deductions, loss or credit, including interest deductions, be adjusted, reallocated or disallowed in a manner that adversely affects our unitholders.

The U.S. Congress has considered legislation that would have (i) in some cases after a ten-year period, precluded us from qualifying as a partnership or required us to hold carried interest through taxable subsidiary corporations and (ii) taxed certain income and gains at increased rates. If any similar legislation were to be enacted and apply to us, the after tax income and gain related to our business, as well as the market price of our units, could be reduced.

        Over the past several years, a number of legislative and administrative proposals have been introduced and, in certain cases, have been passed by the U.S. House of Representatives. In May 2010 the U.S. House of Representatives passed legislation, or the "May 2010 House bill", that would have, in general, treated income and gains, including gain on sale, attributable to an interest in an investment services partnership interest, or "ISPI", as income subject to a new blended tax rate that is higher than under current law, except to the extent such ISPI would have been considered under the legislation to be a qualified capital interest. Your interest in us, our interest in KKR Fund Holdings L.P. and the interests that KKR Fund Holdings L.P. holds in entities that are entitled to receive carried interest may have been classified as ISPIs for purposes of this legislation. The U.S. Senate considered but did not pass similar legislation. On February 14, 2012, Representative Levin introduced similar legislation, or the "2012 Levin bill", that would tax carried interest at ordinary income tax rates (which would be higher than the proposed blended rate under the May 2010 House bill). It is unclear when or whether the U.S. Congress will pass such legislation or what provisions will be included in any legislation, if enacted.

        Both the May 2010 House bill and the 2012 Levin bill provided that, for taxable years beginning ten years after the date of enactment, income derived with respect to an ISPI that is not a qualified capital interest and that is subject to the rules discussed above would not meet the qualifying income

37

Table of Contents

requirements under the publicly traded partnership rules. Therefore, if similar legislation is enacted, following such ten-year period, we would be precluded from qualifying as a partnership for U.S. federal income tax purposes or be required to hold all such ISPIs through corporations, possibly U.S. corporations. If we were taxed as a U.S. corporation or required to hold all ISPIs through corporations, our effective tax rate would increase significantly. The federal statutory rate for corporations is currently 35%. In addition, we could be subject to increased state and local taxes. Furthermore, you could be subject to tax on our conversion into a corporation or any restructuring required in order for us to hold our ISPIs through a corporation. KKR's principals and other professionals could face additional adverse tax consequences under the legislation, which might thereby adversely affect KKR's ability to offer attractive incentive opportunities for key personnel.

        On September 12, 2011, the Obama administration submitted similar legislation to Congress in the American Jobs Act that would tax income and gain, now treated as capital gains, including gain on disposition of interests, attributable to an ISPI at rates higher than the capital gains rate applicable to such income under current law, with an exception for certain qualified capital interests. The proposed legislation would also characterize certain income and gain in respect of ISPIs as non-qualifying income under the publicly traded partnership rules after a ten-year transition period from the effective date, with an exception for certain qualified capital interests. This proposed legislation follows several prior statements by the Obama administration in support of changing the taxation of carried interest. Furthermore, in the proposed American Jobs Act, the Obama administration proposed that current law regarding the treatment of carried interest be changed for taxable years ending after December 31, 2012 to subject such income to ordinary income tax. In its published revenue proposal for 2013, the Obama administration proposed that the current law regarding treatment of carried interest be changed to subject such income to ordinary income tax. The Obama administration's published revenue proposals for 2010, 2011 and 2012 contained similar proposals.

        States and other jurisdictions have also considered legislation to increase taxes with respect to carried interest. For example, New York has periodically considered legislation under which you could be subject to New York state income tax on income in respect of our common units as a result of certain activities of our affiliates in New York, although it is unclear when or whether such legislation will be enacted.

        If the proposed legislation described above or any similar legislation were to be enacted and apply to us, the after tax income and gain related to our business, as well as the market price of our units, could be reduced.

Additional proposed changes in the U.S. taxation of businesses could adversely affect us.

        On February 22, 2012, the Obama administration announced its framework of key elements to change the U.S. federal income tax rules for businesses. Few specifics were included, and it is unclear what any actual legislation could provide, when it would be proposed or what its prospects for enactment could be. Several parts of the framework if enacted could adversely affect us. First, the framework could reduce the deductibility of interest for corporations in some manner not specified. A reduction in interest deductions could increase our tax rate and thereby reduce cash available for distribution to unitholders or for other uses by us. Such a reduction could also limit our ability to finance new transactions and increase the effective cost of financing by companies in which we invest, which could reduce the value of our carried interest in respect of such companies. The framework could also reduce the top marginal tax rate on corporations from 35% to 28%. The framework also suggests that some entities currently treated as partnerships for tax purposes could be subject to an entity-level income tax similar to the corporate income tax. If such a proposal caused us to be subject to additional entity-level taxes, it could reduce cash available for distribution to unitholders or for other uses by us. The framework reiterates the President's support for treatment of carried interest as ordinary income, as provided in the President's revenue proposal for 2013 described above. However,

whether the President's framework will actually be enacted by the government is unknown, and the ultimate consequences of tax reform legislation, if any, are also presently not known.

        The House of Representatives has also proposed the migration of the United States from a "worldwide" system of taxation, pursuant to which U.S. corporations are taxed on their worldwide income, to a territorial tax system where U.S. corporations are taxed only on their U.S. source income (subject to certain exceptions for income derived in low-tax jurisdictions from the exploitation of intangible assets) at a top corporate tax rate that would be 25%. The territorial tax system proposals envisage a revenue neutral result and consequently include revenue raisers to offset the reduction in the tax rate and base which may or may not be detrimental to the value of our common units. Whether these proposals will be enacted by the government and in what form is unknown, as are the ultimate consequences of the proposed legislation.

We depend on our founders and other key personnel, the loss of whose services could have a material adverse effect on our business, results and financial condition.

        We depend on the efforts, skills, reputations and business contacts of our principals, including our founders, Henry Kravis and George Roberts, and other key personnel, the information and deal flow they and others generate during the normal course of their activities and the synergies among the diverse fields of expertise and knowledge held by our professionals. Accordingly, our success depends on the continued service of these individuals, who are not obligated to remain employed with us. The loss of the services of any of them could have a material adverse effect on our revenues, net income and cash flows and could harm our ability to maintain or grow AUM in existing funds or raise additional funds in the future.

        Our principals and other key personnel possess substantial experience and expertise and have strong business relationships with investors in our funds and other members of the business community. As a result, the loss of these personnel could jeopardize our relationships with investors in our funds and members of the business community and result in the reduction of AUM or fewer investment opportunities. For example, if any of our principals were to join or form a competing firm, our business, results and financial condition could suffer.

        Furthermore, the agreements governing our private equity funds and certain non-private equity investment funds managed by us provide that in the event certain "key persons" in these funds (for example, both of Messrs. Kravis and Roberts for our private equity funds, and, in the case of certain geographically or product focused funds, one or more of the executives focused on such funds) generally cease to actively manage a fund, investors in the fund will be entitled to: (i) in the case of our private equity funds, reduce, in whole or in part, their capital commitments available for further investments; and (ii) in the case of certain of our fixed income or other non-private equity investment funds, withdraw all or any portion of their capital accounts, in each case on an investor-by-investor basis (which could lead possibly to a liquidation of those funds). The occurrence of such an event would likely have a significant negative impact on our revenue, net income and cash flow.

If we cannot retain and motivate our principals and other key personnel and recruit, retain and motivate new principals and other key personnel, our business, results and financial condition could be adversely affected.

        Our most important asset is our people, and our continued success is highly dependent upon the efforts of our principals and other professionals, and to a substantial degree on our ability to retain and motivate our principals and other key personnel and to strategically recruit, retain and motivate new talented personnel, including new principals. However, we may not be successful in these efforts as the market for qualified investment professionals is extremely competitive. Our ability to recruit, retain and motivate our professionals is dependent on our ability to offer highly attractive incentive opportunities. If legislation, such as the legislation proposed in April 2009 (and reproposed in 2010 and 2012) were to be enacted, income and gains recognized with respect to carried interest would be treated for U.S.

federal income tax purposes as ordinary income rather than as capital gain. Such legislation would materially increase the amount of taxes that we, our principals and other professionals would be required to pay, thereby adversely affecting our ability to offer such attractive incentive opportunities. See "—Risks Related to U.S. Taxation". In addition, there are pending laws and regulations that seek to regulate the compensation of certain of our employees. See "—Extensive Regulation of our business affects our activities and creates the potential for significant liabilities and penalties. The possibility of increased regulatory focus or legislative or regulatory changes could result in additional burdens on our business." The loss of even a small number of our investment professionals could jeopardize the performance of our funds and other investment products, which would have a material adverse effect on our results of operations. Efforts to retain or attract investment professionals may result in significant additional expenses, which could adversely affect our profitability.

        Many of our principals hold interests in our business through KKR Holdings. These individuals currently receive financial benefits from our business in the form of distributions and amounts funded by KKR Holdings and through their direct and indirect participation in the value of KKR Group Partnership Units held by KKR Holdings. While all of our employees and our principals receive base salaries from us, profit-based cash amounts for certain individuals currently are borne by KKR Holdings from cash reserves based upon distributions on a portion of KKR Group Partnership Units held by KKR Holdings. There can be no assurance that KKR Holdings will have sufficient cash available to continue to make profit-based cash payments and we expect to pay a portion, or eventually all, of these cash bonus payments as KKR Holdings becomes unable to reserve cash for bonus compensation as our principals who hold equity interests through KKR Holdings become entitled to the cash distributions on the KKR Group Partnership Units held by KKR Holdings.

        Moreover, in connection with the KPE Transaction, we made large grants of KKR Holdings units that vest in installments over a five year period commencing October 1, 2009. Our principals may also receive additional equity interests in our business through equity awards granted by KKR Holdings, which does not cause any dilution. However, we have granted and will grant some or all of the types of equity awards historically granted by KKR Holdings from our Equity Incentive Plan, which has caused dilution. In addition, we may be unwilling to grant our employees additional significant equity awards in our business, whether before or even after all of the KKR Holdings units granted in October 2009 vest, and the value of the grants and distributions they receive in respect of their existing awards may be lower than anticipated. This may limit our ability to attract, retain and motivate talented personnel. In order to recruit and retain existing and future investment professionals, we may need to increase the level of compensation that we pay to them, which may cause a higher percentage of our revenue to be paid out in the form of compensation, which would have an adverse impact on our profit margins.

        In addition, there is no guarantee that the confidentiality and restrictive covenant agreements to which our principals are subject, together with our other arrangements with them, will prevent them from leaving us, joining our competitors or otherwise competing with us or that these agreements will be enforceable in all cases. These agreements will expire after a certain period of time, at which point each of our principals would be free to compete against us and solicit investors in our funds, clients and employees. Depending on which entity is a party to these agreements and/or the laws applicable to them, we may not be able to enforce them or become subject to lawsuits or other claims, and certain of these agreements might be waived, modified or amended at any time without our consent. See "Certain Relationships and Related Transactions, and Director Independence—Confidentiality and Restrictive Covenant Agreements."

        We strive to maintain a work environment that reinforces our culture of collaboration, motivation and alignment of interests with fund investors. If we do not continue to develop and implement the right processes and tools to manage our changing enterprise and maintain our culture, our ability to compete successfully and achieve our business objectives could be impaired, which could negatively impact our business, financial condition and results of operations.

Operational risks may disrupt our businesses, result in losses or limit our growth.

        We rely heavily on our financial, accounting and other data processing systems. If any of these systems do not operate properly or are disabled, we could suffer financial loss, a disruption of our businesses, liability to our funds, regulatory intervention or reputational damage. In addition, we operate in businesses that are highly dependent on information systems and technology. Our information systems and technology may not continue to be able to accommodate our growth, may be subject to security risks, and the cost of maintaining such systems may increase from our current level. Such a failure to accommodate growth, or an increase in costs related to such information systems, could have a material adverse effect on our business. Furthermore, we depend on our principal offices in New York City, where most of our administrative personnel are located, for the continued operation of our business. A disaster or a disruption in the infrastructure that supports our businesses, including a disruption involving electronic communications or other services used by us or third parties with whom we conduct business, or directly affecting our principal offices, could have a material adverse impact on our ability to continue to operate our business without interruption. Our business continuation or disaster recovery programs may not be sufficient to mitigate the harm that may result from such a disaster or disruption. In addition, insurance and other safeguards might only partially reimburse us for our losses, if at all. Our operations rely on the secure processing, storage and transmission of confidential and other information in our computer systems and networks. Although we take protective measures and endeavor to modify them as circumstances warrant, our computer systems, software and networks may be vulnerable to unauthorized access, theft, misuse, computer viruses or other malicious code and other events that could have a security impact. If one or more of such events occur, this potentially could jeopardize our or our fund investors' or counterparties' confidential and other information processed and stored in, and transmitted through, our computer systems and networks, or otherwise cause interruptions or malfunctions in our, our fund investors', our counterparties' or third parties' operations, which could result in significant losses, increased costs or reputational damage. Finally, we rely on third party service providers for certain aspects of our business, including for certain information systems, technology, administration, tax and compliance matters. Any interruption or deterioration in the performance of these third parties could impair the quality of our and our funds' operations and could impact our reputation and adversely affect our businesses and limit our ability to grow.

Our organizational documents do not limit our ability to enter into new lines of businesses, and we may expand into new investment strategies, geographic markets and businesses, each of which may result in additional risks and uncertainties in our businesses.

        We intend, to the extent that market conditions warrant, to seek to grow our businesses by increasing AUM in existing businesses, pursuing new investment strategies, including investment opportunities in new asset classes, developing new types of investment structures and products (such as managed accounts and structured products), and expanding into new geographic markets and businesses. We have in recent years opened offices in Asia and the Middle East, and also developed a capital markets business in the United States, Europe, the Middle East and Asia-Pacific, which we intend to grow and diversify. We have also launched a number of new investment initiatives in areas such as real estate, oil and gas, infrastructure and hedge funds. We have and may continue to pursue growth through acquisitions of other investment management companies, acquisitions of critical business partners, strategic partnerships or other strategic initiatives, which may include entering into new lines of business. In addition, we expect opportunities will arise to acquire other alternative or traditional investment managers. To the extent we make strategic investments or acquisitions, undertake other strategic initiatives or enter into a new line of business, we will face numerous risks and uncertainties, including risks associated with:

•

the required investment of capital and other resources;

41

---

Table of Contents

•

the possibility that we have insufficient expertise to engage in such activities profitably or without incurring inappropriate amounts of risk or liability or have not appropriated planned for such activities;



•

the possibility of diversion of management's attention from our core business;



•

the possibility of disruption of our ongoing business;



•

combining, integrating or developing operational and management systems and controls;



•

potential increase in concentration of the investors in our funds;



•

disagreements with joint venture partners or other stakeholders in strategic partnerships; and



•

the broadening of our geographic footprint, including the risks associated with conducting operations in foreign jurisdictions, including taxation.

        Entry into certain lines of business may subject us to new laws and regulations with which we are not familiar, or from which we are currently exempt, and may lead to increased litigation and regulatory risk. If a new business generates insufficient revenues or if we are unable to efficiently manage our expanded operations, our results of operations will be adversely affected. Our strategic initiatives may include joint ventures, in which case we will be subject to additional risks and uncertainties in that we may be dependent upon, and subject to liability, losses or reputational damage relating to, systems, controls and personnel that are not under our control.

We may not be successful in executing upon or managing the complexities of new investment strategies, markets and businesses, which could adversely affect our business, results of operations and financial condition.

        Our growth strategy is based, in part, on the expansion of our platform through selective investment in, and development or acquisition of, businesses and investment strategies complementary to our business. The expansion into new products and geographies has demanded greater management attention and dedication of resources to manage the increasing complexity of operations and regulatory compliance. This growth strategy involves a number of risks, including the risk that the expected synergies from a newly developed product or strategic alliance will not be realized, that the expected results will not be achieved, that new strategies are not appropriately planned for or integrated into the firm, that the new strategies may conflict, detract from or compete against our existing businesses, that the investment process, controls and procedures that we have developed around our existing platform will prove insufficient or inadequate or that our information systems and technology, including related security systems, may prove to be inadequate. For example, the offering of investment products to retail investors, including our funds registered under the 1940 Act, may result in increased compliance and litigation costs. We may also incur significant charges in connection with such investments, which ultimately may result in significant losses and costs. Such losses could adversely impact our business, results of operations and financial condition, as well as do harm to our professional reputation.

If we are unable to syndicate the securities or indebtedness or realize returns on investments financed with our principal assets, our liquidity, business, results of operations and financial condition could be adversely affected.

        Our principal assets provide us with a significant source of capital to grow and expand our business, increase our participation in our transactions and underwrite commitments in our capital markets business. Our principal assets have provided a source of capital to underwrite loans, securities or other financial instruments, which we generally expect to syndicate to third parties. To the extent that we are unable to do so, we may be required to sell such investments at a significant loss or hold them indefinitely. If we are required to retain investments on our balance sheet for an extended period of time, the inability of our capital markets business to complete additional transactions would impair

our results. In addition, as our principal assets have been a significant source of financing for new strategies, to the extent that such strategies are not successful or our principal assets cease to provide adequate liquidity, we would be limited in our ability to seed new businesses or support our existing business as effectively as contemplated.

Extensive regulation of our businesses affects our activities and creates the potential for significant liabilities and penalties. The possibility of increased regulatory focus or legislative or regulatory changes could adversely affect our business.

        Our business is subject to extensive regulation. We are subject to regulation, including periodic examinations, by governmental and self-regulatory organizations in the jurisdictions in which we operate around the world. Many of these regulators, including U.S. and foreign government agencies and self-regulatory organizations, are empowered to conduct investigations and administrative proceedings that can result in fines, suspensions of personnel or other sanctions, including censure, the issuance of cease-and-desist orders or the suspension or expulsion of applicable licenses and memberships. Even if an investigation or proceeding does not result in a sanction or the sanction imposed against us or our personnel by a regulator were small in monetary amount, the adverse publicity relating to the investigation, proceeding or imposition of these sanctions could harm our reputation and cause us to lose existing clients and fund investors or fail to gain new clients and fund investors.

        As a result of market disruptions in the past years as well as highly publicized financial scandals, regulators and fund investors exhibited concerns over the integrity of the U.S. and global financial markets. In response, regulators in the United States and elsewhere launched programs of regulatory reform that have broad implications for us and for our funds, as well as for many of the markets in which we and they operate. In addition, the private equity industry has come under increased political, regulatory and news media scrutiny with politicians, governmental officials, and regulators focusing on the taxation of carried interest and the private equity industry's allocation of expenses to the funds and valuation practices. Any changes in the regulatory framework applicable to our business, including the changes and potential changes described below, as well as adverse news media attention, may impose additional expenses or capital requirements on us, limit our fundraising for our investment products, result in limitations in the manner in which our business is conducted, have an adverse impact upon our financial condition, results of operations or prospects, impair executive retention or recruitment and require substantial attention by senior management. It is impossible to determine the extent of the impact of any new laws, regulations or initiatives that may be proposed or may become law on our business or the markets in which we operate. If enacted, any new regulation or regulatory framework could negatively impact our funds and us in a number of ways, including increasing our costs and the cost for our funds of investing, borrowing or hedging, increasing the funds' or our regulatory costs, imposing additional burdens on the funds' or our staff, and potentially requiring the disclosure of sensitive information. In addition, we may be adversely affected by changes in the interpretation or enforcement of existing laws and rules by these governmental authorities and self-regulatory organizations. New laws or regulations could make compliance more difficult or more expensive or affect the manner in which we conduct business. Moreover, we anticipate the potential for an increase in regulatory investigations and new or enhanced reporting requirements of the trading and other investment activities of alternative investment management funds and firms, including our funds and us. Such investigations and reporting obligations will likely impose additional expenses on us, may require the attention of senior management and increase the complexity of managing our business and may result in fines if we or any of our funds are deemed to have violated any regulations.

        There have been a number of legislative or regulatory proposals affecting the financial sector in the United States. In particular, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or

43

Table of Contents

Dodd-Frank Act, that President Obama signed into law on July 21, 2010, creates a significant amount of new regulation. The Dodd-Frank Act:

•

establishes the Financial Stability Oversight Council, or FSOC, a federal agency charged with, among other things, designating systemically important nonbank financial companies for heightened prudential supervision and making recommendations regarding the imposition of enhanced standards regarding capital, leverage, conflicts and other requirements for financial firms deemed to pose a systemic threat to the financial stability of the U.S. economy;



•

requires private equity and hedge fund advisers to register with the SEC under the Investment Advisers Act (as described elsewhere in this report, Kohlberg Kravis Roberts & Co. L.P. and its wholly-owned subsidiaries KKR Asset Management LLC and Prisma Capital Partners LP are registered with the SEC as investment advisers under the Investment Advisers Act), to maintain extensive records and to file reports if deemed necessary for purposes of systemic risk assessment by certain governmental bodies;



•

authorizes federal regulatory agencies to review and, in certain cases, prohibit compensation arrangements at financial institutions that give employees incentives to engage in conduct deemed to encourage inappropriate risk taking by covered financial institutions;



•

requires public companies to adopt and disclose policies requiring, in the event the company is required to issue an accounting restatement, the clawback of related incentive compensation from current and former executive officers;



•

restricts the ability of banking organizations to sponsor or invest in private equity and hedge funds;



•

grants the U.S. government resolution authority to liquidate or take emergency measures with regard to troubled financial institutions that fall outside the existing resolution authority of the Federal Deposit Insurance Corporation, or FDIC; and



•

creates a Consumer Financial Protection Bureau within the U.S. Federal Reserve.

        Many of these provisions are subject to further rule making and to the discretion of regulatory bodies, such as the FSOC. For example, the following rulemaking has been enacted and the following notices of proposed rulemakings have recently been announced that may apply to us or our subsidiaries:

•

On April 3, 2012, the FSOC issued a final rule and interpretive guidance regarding the process by which it will designate nonbank financial companies as systemically important. The rule and guidance detail a three stage review process, with the level of scrutiny increasing at each stage. During the first stage, the FSOC will apply a broad set of uniform quantitative metrics to identify nonbank financial companies that warrant additional review. In this first stage, the FSOC will consider whether a nonbank financial company has at least $50 billion in total consolidated assets and whether it meets other thresholds relating to credit default swaps outstanding, derivative liabilities, loans and bonds outstanding, a minimum leverage ratio of total consolidated assets to total equity of 15 to 1, and a short-term debt ratio of debt (with maturities less than 12 months) to total consolidated assets of 10%. A company that meets both the asset test and at least one of the other thresholds will be subject to additional review. Although we believe we should not currently be designated as systemically important under the Stage 1 criteria outlined above, those criteria as well as our business are likely to evolve over time. Additional uncertainty is created because the FSOC retains authority to designate any nonbank financial company as systemically important, even if the company does not meet the Stage 1 criteria. The FSOC will consider in the future whether to establish "an additional set of metrics or thresholds tailored to evaluate hedge funds and private equity firms and their advisers." The preamble to the final rule notes that less regulatory data is generally available for

44

Table of Contents

hedge funds and private equity firms, but indicates that, in developing any such additional metrics or thresholds, it intends to review financial disclosures that private fund advisers are required to file with the SEC and CFTC, as further described below. If the FSOC were to determine that we were a systemically important nonbank financial company, we would be subject to a heightened degree of regulation, including more stringent standards relating to capital, leverage, liquidity, risk management, resolution planning and credit exposure reporting and concentration limits, restrictions on acquisitions and annual stress testing by the Federal Reserve. There can be no assurance that nonbank financial firms such as us will not become subject to the aforementioned restrictions or other requirements for financial firms deemed to be systemically important to the financial stability of the U.S. economy.

•

The Dodd-Frank Act, under what has become known as the "Volcker Rule," generally prohibits depository institution holding companies (including foreign banks with U.S. branches and insurance companies with U.S. depository institution subsidiaries), insured depository institutions and subsidiaries and affiliates of such entities from investing in or sponsoring private equity funds or hedge funds. The Volcker Rule became effective on July 21, 2012, although the final implementing regulations have not yet been issued, and is subject to certain transition periods and exceptions for certain permitted activities that would enable certain institutions subject to the Volcker Rule to continue investing in private equity funds under certain conditions. Until the final regulations have been issued, there will be significant uncertainty regarding the implementation of the Volcker Rule and its practical implications. However, there could be adverse implications for our ability to raise funds from the types of entities mentioned above as a result of this prohibition. On October 11, 2011, the Federal Reserve and other federal regulatory agencies issued proposed rules implementing the Volcker Rule. On April 19, 2012, the Federal Reserve issued a statement clarifying that entities subject to the Volcker Rule will have the full two-year period provided under the statute to fully conform their activities and investments.



•

On October 26, 2011, the SEC adopted a new rule requiring certain advisers to private funds to periodically file reports on a new Form PF. Large private fund advisers including advisers with at least $1.5 billion in assets under management attributable to hedge funds and advisers with at least $2 billion in assets under management attributable to private equity funds are subject to more detailed and in certain cases more frequent reporting requirements. The information will be used by the FSOC in monitoring risks to the U.S. financial system. We plan to make a Form PF filings, and compliance with the extensive reporting requirements of Form PF has required additional management and operational resources and attention.



•

On March 2, 2011, the SEC proposed a rule as part of a joint rule-making effort with federal banking regulators designed to prohibit incentive-based compensation arrangements that encourage inappropriate risk taking by covered financial institutions and are deemed to be excessive, or that may lead to material losses. The proposed rule would cover financial institutions with total consolidated assets of at least $1 billion, including investment advisers and broker-dealers, and provide heightened requirements for financial institutions with total consolidated assets of at least $50 billion. The application of this rule to us could require us to substantially revise our compensation strategy and affect our ability to recruit and retain qualified employees.



•

On February 8, 2011, the Federal Reserve proposed a rule establishing the requirements for determining if a company is "predominantly engaged in financial activities" and defines the terms "significant nonbank financial company" and "significant bank holding company." In particular, the rule would define a "significant nonbank financial company" to mean (i) any systemically important nonbank financial company designated by the FSOC and (ii) any other

nonbank financial company with $50 billion or more in total consolidated assets as determined in accordance with applicable accounting standards.

The Dodd-Frank Act amends the Exchange Act to compensate and protect whistleblowers who voluntarily provide original information to the SEC and establishes a fund to be used to pay whistleblowers who will be entitled to receive a payment equal to between 10% and 30% of certain monetary sanctions imposed in a successful government action resulting from the information provided by the whistleblower.

        As mandated by the Dodd-Frank Act, the Commodity Futures Trading Commission, or CFTC, has proposed or adopted a series of rules to establish a comprehensive new regulatory framework for swaps and security based swaps. For example in November 2011, the CFTC finalized rules instituting position limits on certain commodity futures contracts, as well as any futures and swaps that are economically equivalent. Absent an applicable exemption, the regulations would have required aggregation of positions in accounts in which any person, directly or indirectly, holds an ownership or equity interest of 10% or more, as well as accounts over which that person controls trading. Although, in September 2012, the U.S. District Court for the District of Columbia struck down the CFTC's November 2011 rules, the CFTC may issue new rules that may be substantially similar to the November 2011 rules. If so, and to the extent that we do not qualify for an exemption, we may be required to aggregate the positions of our various investment funds and the positions of our portfolio companies. Although the scope of the new regulatory framework is still unclear, these and other new rules may require us and our portfolio companies to limit our trading activities, and in addition, our funds may have difficulty completing otherwise profitable acquisitions in particular industries or may generate profits that are lower than would otherwise be the case. Monitoring and analysis of whether these new rules would require us to register with the CFTC will require management and operational resources and attention, and registration, if required, could impact our operations and add additional costs associated with ongoing compliance.

        In February 2012, the CFTC issued a final rule that rescinded an exemption from CFTC registration for commodity pool operators in connection with privately offered funds, narrowed an exception from commodity pool operator registration obligations with respect to registered investment companies, and amended related rules and guidance. In addition, under Title VII of the Dodd-Frank Act, the CFTC and SEC have been given regulatory authority over swaps, and have adopted a series of rules to establish a comprehensive new regulatory framework for swaps. These rules may limit the activities of certain of our funds, including our fund of funds, and subject us to new regulation, potentially including registration by us or one or more of our affiliates as commodity pool operators and/or commodity trading advisors.

        The Dodd-Frank Act imposes other regulatory requirements on the trading of swaps, including requirements that most swaps be executed on an exchange or "swap execution facility" and cleared through a clearing house, and that entities acting as dealers or "major swap participants" register in the appropriate category and comply with capital, margin, record-keeping and reporting and business conduct rules. The imposition of these requirements could increase the cost of trading in the derivative markets, which could in turn make it more expensive and difficult for our funds to enter into swaps and other derivatives in the normal course of their business. Moreover, these increased regulatory responsibilities and increased costs could reduce trading levels in the derivative markets by a number of market participants, which could in turn adversely impact liquidity in the markets and expose our funds to greater risks in connection with their trading activities.

        In August 2012, the regulation on OTC Derivatives, Central Counterparties and Trade Repositories (also known as the European Market Infrastructure Regulation, or EMIR) became effective. The requirements of EMIR are expected to be phased in over a number of years, beginning in mid-2013. EMIR imposes a requirement that certain "standardized" derivatives contracts are centrally cleared. Where transactions are not subject to central clearing, techniques must be employed to mitigate the

46

---

Table of Contents

risk presented by the transaction. These risk mitigation techniques include trade confirmation, reconciliation processes, exchange of margin, and the daily mark-to-market of trades. EMIR also requires certain filings by market participants regarding OTC derivatives trades with central trade repositories. The imposition of these requirements could increase the cost of trading in the derivative markets, which could in turn make it more expensive and difficult for our funds to enter into swaps and other derivatives in the normal course of their business. Moreover, these increased regulatory responsibilities and increased costs could reduce trading levels in the derivative markets by a number of market participants, which could in turn adversely impact liquidity in the markets and expose our funds to greater risks in connection with their trading activities.

        In November 2010, the European Parliament and the Council of Ministers adopted the EU Directive on Alternative Investment Fund Managers, or AIFMs. EU member states will be required to implement the Directive into national law by July 2013. The Directive will apply to AIFMs established in the EU and to non-EU AIFMs marketing securities of alternative investment funds, or AIFs, in the EU, subject to certain exemptions. AIFMs established in the EU would be required to seek authorization from their home jurisdiction regulators. Non-EU AIFMs will be ineligible for an EU-wide passport under the Directive until the Commission adopts an implementing measure permitting such registration. Non-EU AIFMs that do not register under the Directive may continue to market fund interests to EU professional investors if and to the extent permitted under national law, subject to certain minimum conditions. Individual member states may impose additional conditions, and preliminary indications are that some member states, including Germany, are likely to do so. The Directive will impose new operating requirements on registered AIFMs, including rules on the structure of remuneration for certain personnel, a threshold for regulatory capital and leverage limits, as well as reporting obligations in respect of controlled EU portfolio companies. The European Commission published the delegated regulation (the Level 2 Regulation), supplementing the Directive with regards to exemptions, general operating conditions, depositaries, leverage, transparency and supervision on December 19, 2012. In February 2013, the European Securities and Market Authority published its final guidelines on sound remuneration principles under the Directive. Other implementing measures remain to be adopted. The Directive, the Level 2 Regulation and EU member state implementing measures could have an adverse effect on our businesses by, among other things, (i) imposing disclosure obligations and restrictions on distributions by EU portfolio companies of the funds we manage, (ii) significantly restricting marketing activities, (iii) potentially requiring changes in our compensation structures for key personnel, thereby potentially affecting our ability to recruit and retain these personnel, and (iv) potentially in effect restricting our funds' investments in companies based in EU countries. The Directive, the Level 2 Regulation and the EU member state implementing measures could limit, both in absolute terms and in comparison to EU-based investment managers and funds, our operating flexibility, our ability to market our funds, and our fund raising and investment opportunities, as well as expose us to conflicting regulatory requirements in the United States and the EU.

        During the course of 2012, the EU has proposed or adopted a series of regulatory initiatives that may impact certain aspects of our business in EU member states. In March 2012, a regulation that limits sovereign and naked short selling of government bonds and stocks, the Short Selling Regulation, became effective. The Short Selling Regulation took effect on November 1, 2012. In June 2012, the European Commission published a legislative proposal for a directive establishing a framework for the recovery and resolution of credit institutions and investment firms. If and when adopted, the Directive will impose new obligations on covered institutions, including preparation of recovery and resolution plans, and give regulators wide-ranging powers. Revisions to the Markets in Financial Instruments Directive that were proposed in October 2011 are likely to be adopted in 2013 and are expected to result in new regulatory burdens, including a requirement to trade certain derivatives on regulated trading venues. The imposition of these requirements could increase our and our funds' costs and the complexity of managing our business and may result in fines if we or any of our funds are deemed to have violated any of the new regulations.

        On January 1, 2011, an amendment to the Capital Requirements Directive (CRD III) entered into force. Among other things, CRD III requires EU member states to introduce stricter controls on remuneration for key employees and risk takers within specified credit institutions and investment firms. The Committee of European Banking Supervisors, or CEBS, published guidelines on the implementation of CRD III in December 2010. Also in December 2010, the UK Financial Services Authority, or FSA, amended its Remuneration Code to reflect CRD III. One of our subsidiaries established in the UK is subject to CRD III. CRD III required changes in our compensation structures for key personnel of this subsidiary, thereby potentially affecting its ability to recruit and retain these personnel.

        In 2010, the Basel Committee on Banking Supervision, an international body comprised of senior representatives of bank supervisory authorities and central banks from 27 countries, including the United States, finalized a comprehensive set of capital and liquidity standards, commonly referred to as "Basel III," for internationally active banking organizations. These new standards, which are expected to be fully phased in by 2019, are expected to require banks to hold more capital, predominantly in the form of common equity, than under the current capital framework. In July 2011, the European Commission published legislative proposals to implement Basel III's capital and liquidity standards by revising the existing Capital Requirements Directive and issuing a new Capital Requirements Regulation, collectively referred to as CRD IV. In June 2012, the U.S. federal banking agencies issued proposed regulations that, among other things, would implement the Basel III capital framework in the United States. Although the Basel III framework provides for implementation of the enhanced capital requirements to begin January 1, 2013, implementation in both Europe and the United States has been indefinitely delayed until these proposed regulations can be finalized. Compliance with the Basel III standards may result in significant costs to banks, which in turn may result in higher borrowing costs for the private sector and reduced access to certain types of credit. Basel III may increase the cost of borrowing by our funds and portfolio companies, which may result in fewer investments being acquired or disposed, lower returns, a decrease in valuations of our investments, or an inability to refinance debt on economic terms. See "—Changes in the debt financing markets may negatively impact the ability of our private equity funds and their portfolio companies to obtain attractive financing for their investments and may increase the cost of such financing if it is obtained, which could lead to lower yielding investments and potentially decrease our net income."

        In October 2011 and November 2012, the Financial Stability Board, or FSB, issued reports that recommended strengthening the oversight and regulation of the so-called shadow banking system, broadly described as credit intermediation involving entities and activities outside the regular banking system. The report outlined initial steps to define the scope of the shadow banking system and proposed general governing principles for a monitoring and regulatory framework. Similarly, in March 2012 the European Commission issued a Green paper on shadow banking building on the work of the FSB. The FSB plans to publish final recommendations for the regulation and oversight of shadow banking in September 2013. While at this stage it is difficult to predict the scope of any new regulations, if such regulations were to extend the regulatory and supervisory requirements, such as capital and liquidity standards, currently applicable to banks, to our funds considered to be engaged in "shadow banking", the regulatory and operating costs of our affected businesses would increase and may become prohibitive.

        We regularly rely on exemptions in the United States from various requirements of the Securities Act, the Exchange Act, the Investment Company Act of 1940, or Investment Company Act, and the U.S. Employee Retirement Income Security Act of 1974, or ERISA, in conducting our investment management activities. These exemptions are sometimes highly complex and may in certain circumstances depend on compliance by third parties whom we do not control. If for any reason these exemptions were to become unavailable to us, we could become subject to regulatory action or third-party claims and our business could be materially and adversely affected. See "—Risks Related to Our

Table of Contents

Organizational Structure—If we were deemed to be an "investment company" subject to regulation under the Investment Company Act, applicable restrictions could make it impractical for us to continue our business as contemplated and could have a material adverse effect on our business."

        On the other hand, we are and will become further subject to additional regulatory and compliance burdens as we expand our product offerings and investment platform to include retail investors. For example, three funds in our Public Markets segment are registered under the 1940 Act as management investment companies. These funds and KKR Asset Management LLC, which serves as their investment adviser, are subject to the 1940 Act and the rules thereunder, which, among other things, regulate the relationship between a registered investment company and its investment adviser and prohibit or severely restrict principal transactions and joint transactions. As our business expands we may be required to make additional registrations, including in jurisdictions outside the U.S. Compliance with these rules will increase our compliance costs and create potential for additional liabilities and penalties the management of which would divert management's attention from our business and investments.

        Other requirements imposed by our regulators are designed primarily to ensure the integrity of the financial markets and to protect investors in our funds and are not designed to protect holders of interests in our business. Consequently, these regulations often serve to limit our activities. In addition, the regulatory environment in which our funds or their investors operate may affect our business. For example, changes in antitrust laws or the enforcement of antitrust laws could affect the level of mergers and acquisitions activity, and changes in state or other local laws may limit investment activities of state pension plans or insurance companies. We may also be adversely affected as a result of new or revised legislation or regulations imposed by the SEC or other governmental regulatory authorities including foreign regulatory authorities or self-regulatory organizations that supervise the financial markets.

        We are also subject to a number of laws and regulations governing payments and contributions to political persons or other third parties, including restrictions imposed by the Foreign Corrupt Practices Act, or FCPA, as well as trade sanctions and other export control laws administered by the Office of Foreign Assets Control, or OFAC, the U.S. Department of Commerce and the U.S. Department of State. The FCPA is intended to prohibit bribery of foreign governments and their officials and political parties, and requires public companies in the United States to keep books and records that accurately and fairly reflect those companies' transactions. OFAC, the U.S. Department of Commerce and the U.S. Department of State administer and enforce various export control laws and regulations, including economic and trade sanctions based on U.S. foreign policy and national security goals against targeted foreign states, organizations and individuals. These laws and regulations relate to a number of aspects of our business, including servicing existing fund investors, finding new fund investors, and sourcing new investments, as well as activities by the portfolio companies in our investment portfolio or other controlled investments.

        The recently enacted Iran Threat Reduction and Syrian Human Rights Act of 2012 ("ITRSHRA") expands the scope of U.S. sanctions against Iran. Notably, ITRSHRA prohibits foreign entities that are majority owned or controlled by U.S. persons from engaging in transactions with Iran that would be contrary to the sanctions regulations if undertaken by a U.S. person. In addition, Section 219 of the ITRSHRA amended the Exchange Act to require public reporting companies to disclose in their annual or quarterly reports any dealings or transactions the company or its affiliates engaged in during the previous reporting period involving Iran or other individuals and entities targeted by certain OFAC sanctions. In some cases, ITRSHRA requires companies to disclose these types of transactions even if they were permissible under U.S. law or were conducted outside of the United States by a foreign affiliate. To our knowledge, none of our activities during the year ended December 31, 2012, are required to be disclosed pursuant to ITRSHRA, except as disclosed in Exhibit 99.1 to this annual report. We are required to separately file, concurrently with this annual report, a notice that such activities have been disclosed in this annual report. The SEC is required to post this notice of

49

---

Table of Contents

disclosure on its website and send the report to the U.S. President and certain U.S. Congressional committees. The U.S. President thereafter is required to initiate an investigation and, within 180 days of initiating such an investigation, to determine whether sanctions should be imposed. Disclosure of such activity, even if such activity is not subject to sanctions under applicable law, and any sanctions actually imposed on us or our affiliates as a result of these activities, could harm our reputation and have a negative impact on our business.

        Similar laws in non-U.S. jurisdictions, such as EU sanctions or the U.K. Bribery Act, as well as other applicable anti-bribery, anti-corruption, anti-money laundering, or sanction or other export control laws in the U.S. and abroad, may also impose stricter or more onerous requirements than the FCPA, OFAC, the U.S. Department of Commerce and the U.S. Department of State, and implementing them may disrupt our business or cause us to incur significantly more costs to comply with those laws. Different laws may also contain conflicting provisions, making compliance with all laws more difficult. If we fail to comply with these laws and regulations, we could be exposed to claims for damages, financial penalties, reputational harm, incarceration of our employees, restrictions on our operations and other liabilities, which could negatively affect our business, operating results and financial condition. In addition, we may be subject to successor liability for FCPA violations or other acts of bribery committed by companies in which we or our funds invest or which we or our funds acquire.

        In June 2010, the SEC approved Rule 206(4)-5 under the Advisers Act regarding "pay to play" practices by investment advisers involving campaign contributions and other payments to government clients and elected officials able to exert influence on such clients. Among other restrictions, the rule prohibits investment advisers from providing advisory services for compensation to a government client for two years, subject to very limited exceptions, after the investment adviser, its senior executives or its personnel involved in soliciting investments from government entities make contributions to certain candidates and officials in position to influence the hiring of an investment adviser by such government client. Advisers are required to implement compliance policies designed, among other matters, to track contributions by certain of the adviser's employees and engagements of third parties that solicit government entities and to keep certain records in order to enable the SEC to determine compliance with the rule. There has also been similar rule-making on a state-level regarding "pay to play" practices by investment advisers, including in California and New York. Any failure on our part to comply with these rules could cause us to lose compensation for our advisory services or expose us to significant penalties and reputational damage.

        Certain laws to which we are subject, such as certain environmental laws, takeover laws, anti-bribery and anti-corruption laws, escheat or abandoned property laws, and antitrust laws, may impose requirements on us and our portfolio companies as an affiliated group and, in some cases, impose concepts such as joint and several liability or notification obligations on affiliates. For example, the United Kingdom introduced a CRC Energy Efficiency Scheme which requires, under certain circumstances, that funds, general partners and portfolio companies participate in the scheme as a single organization and aggregate the energy supplies made to each of them. In addition, the scheme imposes joint and several liability for compliance on the entities within the organization. Moreover, certain non-U.S. jurisdictions may seek to make us liable for the anti-trust violations, if any, committed by certain of our portfolio companies. Similarly, our portfolio companies may be subject to contractual obligations which may impose obligations or restrictions on their affiliates. The interpretation of such contractual provisions will depend on local laws. Given that we do not control all of our portfolio companies and that our portfolio companies generally operate independently of each other, there is a risk that we could contravene one or more of such laws, regulations and contractual arrangements due to limited access and opportunities to monitor compliance. In addition, compliance with these laws or contracts could require us to commit significant resources and capital towards information gathering and monitoring thereby increasing our operating costs.

        Our operations are subject to regulation and supervision in a number of domestic and foreign jurisdictions, and the level of regulation and supervision to which we are subject varies from jurisdiction to jurisdiction and is based on the type of business activity involved. See "Business—Regulation."

We are subject to substantial litigation risks and may face significant liabilities and damage to our professional reputation as a result of litigation allegations and negative publicity.

        The investment decisions we make in our investment management business and the activities of our investment professionals on behalf of our portfolio companies may subject them and us to the risk of third-party litigation arising from dissatisfaction of fund investors with the performance of their funds, the activities of our portfolio companies and a variety of other litigation claims. See the section entitled "Litigation" appearing in Note 15 "Commitments and Contingencies" of our financial statements included elsewhere in this report. By way of example, we, our funds and certain of our employees are each exposed to the risks of litigation relating to investment activities in our funds and actions taken by the officers and directors (some of whom may be KKR employees) of portfolio companies, such as the risk of shareholder litigation by other shareholders of public companies or holders of debt instruments of companies in which our funds have significant investments. We are also exposed to risks of litigation or investigation in the event of any transactions that presented conflicts of interest that were not properly addressed.

        To the extent investors in our investment funds suffer losses resulting from fraud, gross negligence, willful misconduct or other similar misconduct, such investors may have remedies against us, our investment funds, our principals or our affiliates under federal securities law and state law. Investors in our funds do not have legal remedies against us, the general partners of our funds, our funds, our principals or our affiliates solely based on their dissatisfaction with the investment performance of those funds. While the general partners and investment advisers to our investment funds, including their directors, officers, other employees and affiliates, are generally indemnified to the fullest extent permitted by law with respect to their conduct in connection with the management of the business and affairs of our investment funds, such indemnity generally does not extend to actions determined to have involved fraud, gross negligence, willful misconduct or other similar misconduct.

        In addition, we have formed and may continue to form funds targeting retail investors, which may subject us to additional risk of litigation and regulatory scrutiny. See—"Extensive regulation of our businesses affects our activities and creates the potential for significant liabilities and penalties. The possibility of increased regulatory focus or legislative or regulatory changes could adversely affect our business."

        If any lawsuits were brought against us and resulted in a finding of substantial legal liability, the lawsuit could materially adversely affect our business, financial condition or results of operations or cause significant reputational harm to us, which could seriously impact our business. We depend to a large extent on our business relationships and our reputation for integrity and high-caliber professional services to attract and retain fund investors and to pursue investment opportunities for our funds. As a result, allegations of improper conduct by private litigants or regulators, whether the ultimate outcome is favorable or unfavorable to us, as well as negative publicity and press speculation about us, our investment activities or the private equity industry in general, whether or not valid, may harm our reputation, which may be more damaging to our business than to other types of businesses.

        In addition, with a workforce composed of many highly paid professionals, we face the risk of litigation relating to claims for compensation or other damages, which may, individually or in the aggregate, be significant in amount. The cost of settling any such claims could negatively impact our business, financial condition and results of operations.

Misconduct of our employees or at our portfolio companies could harm us by impairing our ability to attract and retain clients and subjecting us to significant legal liability and reputational harm.

        There is a risk that our principals and employees could engage in misconduct that adversely affects our business. We are subject to a number of obligations and standards arising from our business and our authority over the assets we manage. The violation of these obligations and standards by any of our employees would adversely affect our clients and us. We may also be adversely affected if there is misconduct by senior management of portfolio companies in which our funds invest, even though we may be unable to control or mitigate such misconduct. Our business often requires that we deal with confidential matters of great significance to companies in which we may invest. If our employees were improperly to use or disclose confidential information, we could suffer serious harm to our reputation, financial position and current and future business relationships, as well as face potentially significant litigation. It is not always possible to detect or deter employee misconduct, and the extensive precautions we take to detect and prevent this activity may not be effective in all cases. If any of our employees were to engage in misconduct or were to be accused of such misconduct, our business and our reputation could be adversely affected.

We are subject to risks in using prime brokers, custodians, administrators and other agents.

        Certain of our investment funds and our Capital Markets and Principal Activities business depend on the services of prime brokers, custodians, administrators and other agents to carry out certain securities transactions. In the event of the insolvency of a prime broker and/or custodian, our funds may not be able to recover equivalent assets in full as they will rank among the prime broker's and custodian's unsecured creditors in relation to assets which the prime broker or custodian borrows, lends or otherwise uses. In addition, our and our funds' cash held with a prime broker or custodian may not be segregated from the prime broker's or custodian's own cash, and our funds therefore may rank as unsecured creditors in relation thereto. The inability to recover assets from the prime broker or custodian could have a material impact on the performance of our funds and our business, financial condition and results of operations.

Risks Related to the Assets We Manage

        As an investment manager, we sponsor and manage funds and vehicles that make investments worldwide on behalf of third-party investors and, in connection with those activities, are required to deploy our own capital in those investments. The investments of these funds and vehicles are subject to many risks and uncertainties which, to the extent they are material, are discussed below. In addition, we have principal investments and manage those assets on our own behalf. As a result, the gains and losses on such assets are reflected in our net income and the risks set forth below relating to the assets that we manage will directly affect our operating performance.

The historical returns attributable to our funds, including those presented in this report, should not be considered as indicative of the future results of our funds or of our future results or of any returns on our common units.

        We have presented in this report certain information relating to our investment returns, such as net and gross IRRs, multiples of invested capital and realized and unrealized investment values for funds that we have sponsored and managed. The historical and potential future returns of the funds that we manage are not directly linked to returns on KKR Group Partnership Units.

        Moreover, historical returns of our funds may not be indicative of the future results that you should expect from us, which could negatively impact the fees and incentive amounts received by us

from such funds. In particular, our funds' future results may differ significantly from their historical results for the following reasons:

•

the rates of returns of our funds reflect unrealized gains as of the applicable valuation date that may never be realized, which may adversely affect the ultimate value realized from those funds' investments;



•

the historical returns that we present in this report derive largely from the performance of our earlier private equity funds, whereas future fund returns will depend increasingly on the performance of our newer funds, which may have little or no investment track record, and in particular you will not benefit from any value that was created in our funds prior to the KPE Transaction to the extent such value has been realized and we may be required to repay excess amounts previously received in respect of carried interest in our funds if, upon liquidation of the fund, we have received carried interest distributions in excess of the amount to which we were entitled;



•

the future performance of our funds will be affected by macroeconomic factors, including negative factors arising from recent disruptions in the global financial markets that were not prevalent in the periods relevant to the historical return data included in this report;



•

in some historical periods, the rates of return of some of our funds have been positively influenced by a number of investments that experienced a substantial decrease in the average holding period of such investments and rapid and substantial increases in value following the dates on which those investments were made; the actual or expected length of holding periods related to investments is likely longer than such historical periods; those trends and rates of return may not be repeated in the future;



•

our newly established funds may generate lower returns during the period that they take to deploy their capital;



•

our funds' returns have benefited from investment opportunities and general market conditions in certain historical periods that may not repeat themselves, and there can be no assurance that our current or future funds will be able to avail themselves of comparable investment opportunities or market conditions; and



•

we may create new funds and investment products in the future that reflect a different asset mix in terms of allocations among funds, investment strategies, geographic and industry exposure, vintage year and economic terms.

        In addition, our historical rates of return reflect our historical cost structure, which may vary in the future, and future returns will be affected by the risks described elsewhere in this report, including risks of the industry sectors and businesses in which a particular fund invests and changes in laws. See "—Risks Related to our Business—Difficult market conditions can adversely affect our business in many ways, including by reducing the value or performance of the investments that we manage or by reducing the ability of our funds to raise or deploy capital, each of which could negatively impact our net income and cash flow and adversely affect our financial condition."

Valuation methodologies for certain assets in our funds can be subjective and the fair value of assets established pursuant to such methodologies may never be realized, which could result in significant losses for our funds.

        There are no readily ascertainable market prices for a substantial majority of illiquid investments of our investment funds and our finance vehicles. When determining fair values of investments, we use the last reported market price as of the statement of financial condition date for investments that have readily observable market prices. When an investment does not have a readily available market price,

53

---

Table of Contents

the fair value of the investment represents the value, as determined by us in good faith, at which the investment could be sold in an orderly disposition over a reasonable period of time between willing parties other than in a forced or liquidation sale. There is no single standard for determining fair value in good faith and in many cases fair value is best expressed as a range of fair values from which a single estimate may be derived. When making fair value determinations, we typically use a market multiples approach that considers a specified financial measure (such as EBITDA) and/or a discounted cash flow analysis. We also consider a range of additional factors that we deem relevant, including the applicability of a control premium or illiquidity discount, the presence of significant unconsolidated assets and liabilities, any favorable or unfavorable tax attributes, the method of likely exit, financial projections, estimates of assumed growth rates, terminal values, discount rates including risk free rates, capital structure, risk premiums and other factors, and determining these factors may involve a significant degree of our management's judgment and the judgment of management of our portfolio companies. Changes in these factors can have a significant effect on the results of the valuation methodologies used to value our portfolio, and our reported fair values for these assets could vary materially if the inputs and other assumptions used from prior quarters were to change significantly. For example, if applicable interest rates rise, then the assumed cost of capital for these assets would be expected to increase under a discounted cash flow analysis, and this effect would negatively impact their valuations if not offset by other factors. Conversely, a fall in interest rates would be expected to positively impact valuations of these assets if not offset by other factors.

        Because valuations, and in particular valuations of investments for which market quotations are not readily available, are inherently uncertain, may fluctuate over short periods of time and may be based on estimates, determinations of fair value may differ materially from the values that would have resulted if a ready market had existed. Even if market quotations are available for our investments, such quotations may not reflect the value that we would actually be able to realize because of various factors, including possible illiquidity. Our partners' capital could be adversely affected if the values of investments that we record is materially higher than the values that are ultimately realized upon the disposal of the investments and changes in values attributed to investments from quarter to quarter may result in volatility in our AUM and such changes could materially affect the results of operations that we report from period to period. There can be no assurance that the investment values that we record from time to time will ultimately be realized and that you will be able to realize the investment values that are presented in this report.

        Because there is significant uncertainty in the valuation of, or in the stability of the value of, illiquid investments, the fair values of investments reflected in an investment fund's or finance vehicle's net asset value, or NAV, do not necessarily reflect the prices that would actually be obtained by us on behalf of the fund or finance vehicle when such investments are realized. Realizations at values significantly lower than the values at which investments have been reflected in prior fund NAVs would result in losses for the applicable fund and the loss of potential carried interest and other fees. Also, if realizations of our investments produce values materially different than the carrying values reflected in prior fund NAVs, fund investors may lose confidence in us, which could in turn result in difficulty in raising capital for future funds.

        Even if market quotations are available for our investments, such quotations may not reflect the value that could actually be realized because of various factors, including the possible illiquidity associated with a large ownership position, subsequent illiquidity in the market for a company's securities, future market price volatility or the potential for a future loss in market value based on poor industry conditions or the market's view of overall company and management performance.

        In addition, because we value our entire portfolio only on a quarterly basis, subsequent events that may have a material impact on those valuations may not be reflected until the next quarterly valuation date.

Dependence on significant leverage in investments by our funds could adversely affect our ability to achieve attractive rates of return on those investments.

        Because many of our funds' investments rely heavily on the use of leverage, our ability to achieve attractive rates of return on investments will depend on our continued ability to access sufficient sources of indebtedness at attractive rates. For example, our fixed income funds use varying degrees of leverage when making investments. Similarly, in many private equity investments, indebtedness may constitute 70% or more of a portfolio company's total debt and equity capitalization, including debt that may be incurred in connection with the investment, and a portfolio company's indebtedness may also increase in recapitalization transactions subsequent to the company's acquisition. The absence of available sources of sufficient debt financing for extended periods of time could therefore materially and adversely affect our funds and our portfolio companies. Also, an increase in either the general levels of interest rates or in the risk spread demanded by sources of indebtedness such as we experienced during 2009 would make it more expensive to finance those investments. In addition, increases in interest rates could decrease the value of fixed-rate debt investments that our finance vehicles or our funds make. Increases in interest rates could also make it more difficult to locate and consummate private equity and other investments because other potential buyers, including operating companies acting as strategic buyers, may be able to bid for an asset at a higher price due to a lower overall cost of capital or their ability to benefit from a higher amount of cost savings following the acquisition of the asset. In addition, a portion of the indebtedness used to finance private equity investments often includes high-yield debt securities issued in the capital markets. Capital markets are volatile, and there may be times when we might not be able to access those markets at attractive rates, or at all, when completing an investment.

        Investments in highly leveraged entities are also inherently more sensitive to declines in revenues, increases in expenses and interest rates and adverse economic, market and industry developments. The incurrence of a significant amount of indebtedness by an entity could, among other things:

•

subject the entity to a number of restrictive covenants, terms and conditions, any violation of which would be viewed by creditors as an event of default and could materially impact our ability to realize value from our investment;



•

allow even moderate reductions in operating cash flow to render it unable to service its indebtedness;



•

give rise to an obligation to make mandatory prepayments of debt using excess cash flow, which might limit the entity's ability to respond to changing industry conditions to the extent additional cash is needed for the response, to make unplanned but necessary capital expenditures or to take advantage of growth opportunities;



•

limit the entity's ability to adjust to changing market conditions, thereby placing it at a competitive disadvantage compared to its competitors who have relatively less debt;



•

limit the entity's ability to engage in strategic acquisitions that might be necessary to generate attractive returns or further growth; and



•

limit the entity's ability to obtain additional financing or increase the cost of obtaining such financing, including for capital expenditures, working capital or other general corporate purposes.

        A leveraged company's income and equity also tend to increase or decrease at a greater rate than would otherwise be the case if money had not been borrowed. As a result, the risk of loss associated with a leveraged company is generally greater than for comparable companies with comparatively less debt. For example, leveraged companies could default on their debt obligations due to a decrease in

55

Table of Contents

revenues and cash flow precipitated by an economic downturn or by poor relative performance at such a company.

        When our funds' existing portfolio investments reach the point when debt incurred to finance those investments matures in significant amounts and must be either repaid or refinanced, those investments may materially suffer if they have generated insufficient cash flow to repay maturing debt and there is insufficient capacity and availability in the financing markets to permit them to refinance maturing debt on satisfactory terms, or at all. If the financing for such purposes were to be unavailable or uneconomic when significant amounts of the debt incurred to finance our funds' existing portfolio investments start to come due, these investments could be materially and adversely affected. In the event of default or potential default under applicable financing arrangements, one or more of our portfolio companies may go bankrupt, which could give rise to substantial investment losses, adverse claims or litigation against us or our employees and damage to our reputation.

        The majority-owned subsidiaries of KFN, the publicly traded specialty finance company managed by us, regularly use and have used significant leverage to finance their assets. An inability by such subsidiaries to continue to raise or utilize leverage, to refinance or extend the maturities of their outstanding indebtedness or to maintain adequate levels of collateral under the terms of their collateralized loan obligations could limit their ability to grow their business, reinvest principal cash, distribute cash to KFN or fully execute their business strategy, and KFN's results of operations may be adversely affected. If KFN is unable to maintain its operating results and access to capital resources, KFN could face substantial liquidity problems and might be required to dispose of material assets or operations to meet its debt service and other obligations.

        Among the sectors particularly challenged by downturns in the global credit markets, including the downturn experienced from 2008 through 2010, are the CLO and leveraged finance markets. KFN has significant exposure to these markets through its CLO subsidiaries, each of which is a special purpose company that issued to KFN and other investors notes secured by a pool of collateral consisting primarily of corporate leveraged loans. In most cases, KFN's CLO holdings are deeply subordinated, representing the CLO subsidiary's substantial leverage, which increases both the opportunity for higher returns as well as the magnitude of losses when compared to holders or investors that rank more senior to KFN in right of payment. KFN's CLO subsidiaries have historically experienced an increase in downgrades, depreciations in market value and defaults in respect of leveraged loans in their collateral during downturns in credit markets. There can be no assurance that market conditions giving rise to these types of consequences will not occur, re-occur, subsist or become more acute in the future. Because KFN's CLO structures involve complex collateral and other arrangements, the documentation for such structures is complex, is subject to differing interpretations and involves legal risk. In July 2009, KFN surrendered for cancellation approximately $298.4 million in aggregate of notes issued to it by certain of its CLOs. The surrendered notes were cancelled and the obligations due under such notes were deemed extinguished.

        Our hedge fund solutions strategy and our long/short equity fund, credit-oriented funds and CLOs may choose to use leverage as part of their respective investment programs and regularly borrow a substantial amount of their capital. The use of leverage poses a significant degree of risk and enhances the possibility of a significant loss in the value of the investment portfolio. A fund may borrow money from time to time to purchase or carry securities or debt obligations or may enter into derivative transactions (such as total return swaps) with counterparties that have embedded leverage. The interest expense and other costs incurred in connection with such borrowing may not be recovered by appreciation in the securities purchased or carried and will be lost—and the timing and magnitude of such losses may be accelerated or exacerbated—in the event of a decline in the market value of such securities or debt obligations. Gains realized with borrowed funds may cause the fund's net asset value to increase at a faster rate than would be the case without borrowings. However, if investment results fail to cover the cost of borrowings, the fund's net asset value could also decrease faster than if there had been no borrowings.

        Any of the foregoing circumstances could have a material adverse effect on our financial condition, results of operations and cash flow.

The due diligence process that we undertake in connection with our investments may not reveal all facts that may be relevant in connection with an investment.

        Before making our investments, we conduct due diligence that we deem reasonable and appropriate based on the facts and circumstances applicable to each investment. The objective of the due diligence process is to identify attractive investment opportunities based on the facts and circumstances surrounding an investment, to identify possible risks associated with that investment and, in the case of private equity investments, to prepare a framework that may be used from the date of an acquisition to drive operational achievement and value creation. When conducting due diligence, we typically evaluate a number of important business, financial, tax, accounting, environmental and legal issues in determining whether or not to proceed with an investment. Outside consultants, legal advisors, accountants and investment banks are involved in the due diligence process in varying degrees depending on the type of investment. Nevertheless, when conducting due diligence and making an assessment regarding an investment, we rely on resources available to us, including information provided by the target of the investment and, in some circumstances, third-party investigations. The due diligence process may at times be subjective with respect to newly organized companies for which only limited information is available. The due diligence conducted for certain of our Public Markets strategies is limited to publicly available information. Accordingly, we cannot be certain that the due diligence investigation that we will carry out with respect to any investment opportunity will reveal or highlight all relevant facts (including fraud, bribery and other illegal activities and contingent liabilities) that may be necessary or helpful in evaluating such investment opportunity, including the existence of contingent liabilities. We also cannot be certain that our due diligence investigations will result in investments being successful or that the actual financial performance of an investment will not fall short of the financial projections we used when evaluating that investment.

        When we conduct due diligence in making and monitoring investments in third party hedge funds, we rely on information supplied by third party hedge funds or by service providers to such third party hedge funds. The information we receive from them may not be accurate or complete and therefore we may not have all the relevant facts necessary to properly assess and monitor our funds' investment in a particular hedge fund.

Our investment management activities involve investments in relatively high-risk, illiquid assets, and we may fail to realize any profits from these activities for a considerable period of time or lose some or all of the capital invested.

        Many of our funds hold investments in securities that are not publicly traded. In many cases, our funds may be prohibited by contract or by applicable securities laws from selling such securities at many points in time. Our funds will generally not be able to sell these securities publicly unless their sale is registered under applicable securities laws, or unless an exemption from such registration is available, and then only at such times when we do not possess material nonpublic information. The ability of many of our funds to dispose of investments is heavily dependent on the capital markets and in particular the public equity markets. For example, the ability to realize any value from an investment may depend upon the ability to complete an initial public offering of the portfolio company in which such investment is made. Even if the securities are publicly traded, large holdings of securities can often be disposed of only over a substantial length of time, exposing our investment returns to risks of downward movement in market prices during the intended disposition period. In addition, as certain of our funds have a finite term, we could be forced to dispose of investments sooner than otherwise desirable. Accordingly, under certain conditions, our funds may be forced to either sell securities at lower prices than they had expected to realize or defer sales that they had planned to make, potentially

for a considerable period of time. We have made and expect to continue to make significant capital investments in our current and future funds. Contributing capital to these funds is risky, and we may lose some or all of the principal amount of our investments.

The investments of our funds are subject to a number of inherent risks.

        Our results are highly dependent on our continued ability to generate attractive returns from our investments. Investments made by our private equity, credit or other investments involve a number of significant risks inherent to private equity, credit and other investing, including the following:

•

companies in which investments are made may have limited financial resources and may be unable to meet their obligations under their securities, which may be accompanied by a deterioration in the value of their equity securities or any collateral or guarantees provided with respect to their debt;



•

companies in which investments are made are more likely to depend on the management talents and efforts of a small group of persons and, as a result, the death, disability, resignation or termination of one or more of those persons could have a material adverse impact on their business and prospects;



•

companies in which investments are made may from time to time be parties to litigation, may be engaged in rapidly changing businesses with products subject to a substantial risk of obsolescence and may require substantial additional capital to support their operations, finance expansion or maintain their competitive position;



•

instances of fraud and other deceptive practices committed by senior management of portfolio companies in which our funds invest may undermine our due diligence efforts with respect to such companies, and if such fraud is discovered, negatively affect the valuation of a fund's investments as well as contribute to overall market volatility that can negatively impact a fund's investment program;



•

our funds may make investments that they do not advantageously dispose of prior to the date the applicable fund is dissolved, either by expiration of such fund's term or otherwise, resulting in a lower than expected return on the investments and, potentially, on the fund itself;



•

our portfolio companies generally have capital structures established on the basis of financial projections based primarily on management judgments and assumptions, and general economic conditions and other factors may cause actual performance to fall short of these financial projections, which could cause a substantial decrease in the value of our equity holdings in the portfolio company and cause our funds' performance to fall short of our expectations;



•

certain of our investment funds may invest in securities of companies that are experiencing significant financial or business difficulties, which are subject to greater legal and regulatory complexities and may be subject to a greater risk of poor performance or loss; and



•

executive officers, directors and employees of an equity sponsor may be named as defendants in litigation involving a company in which an investment is made or is being made, and we or our funds may indemnify such executive officers, directors or employees for liability relating to such litigation.

Our investments in real assets such as real estate, infrastructure assets and natural resources may expose us to increased risks and liabilities and may expose our unitholders to adverse tax consequences.

        Investments in real assets, which may include real estate, infrastructure assets, oil and gas properties and other natural resources, may expose us to increased risks and liabilities that are inherent in the ownership of real assets. For example, ownership of real assets in our funds or vehicles may

58

---

Table of Contents

increase our risk of liability under environmental laws that impose, regardless of fault, joint and several liability for the cost of remediating contamination and compensation for damages. Ownership of real assets may also present additional risk of liability for personal and property injury or impose significant operating challenges and costs, for example with respect to compliance with zoning, environmental or other applicable laws.

        Without limiting the foregoing disclosure, we note that investments that we have made and will continue to make in the oil and gas industries may present specific environmental, safety and other inherent risks, and such investments are subject to stringent and complex foreign, federal, state and local laws, ordinances and regulations specific to oil and gas industries, for example governing controls, taxes, transportation of oil and natural gas, exploration and production, permitting, and various conservation laws and regulations applicable to oil and natural gas production and related operations in addition to regulations governing occupational health and safety, the discharge of materials into the environment or otherwise relating to environmental protection. Failure to comply with applicable laws and regulations may result in the assessment of administrative, civil and criminal penalties, the imposition of remedial obligations and the issuance of orders enjoining some or all of our operations in affected areas. These laws and regulations may also restrict the rate of oil and natural gas production below the rate that would otherwise be possible and increase the cost of production thus reducing profitability. Our oil and gas investments are subject to other risks, such as:

•

Currently unforeseen environmental incidents may occur or past non-compliance with environmental laws or regulations may be discovered making it difficult to predict the future costs or impact of compliance.



•

The oil and gas industries present inherent risk of personal and property injury, for which we may not be fully insured.



•

Our estimated oil, natural gas, and natural gas liquids reserve quantities and future production rates are based on many assumptions that may prove to be inaccurate. Any material inaccuracies in these reserve estimates or the underlying assumptions will materially affect the quantities and value of our reserves.



•

The performance of our natural resources investments depend on the skill, ability and decisions of third party operators. Failure of such operators to comply with applicable laws, rules and regulations could result in liabilities to us, reduce the value of our interest in the oil and natural gas properties, adversely affect our cash flows and results of operations.



•

If commodity prices decline and remain depressed for a prolonged period, a significant portion of our development projects may become uneconomic and cause write downs of the value of our oil and natural gas properties, which may reduce the value of our natural resources investments, have a negative impact on our ability to use these investments as collateral or otherwise have a material adverse effect on our results of operations.

        Investments in real estate will be subject to the risks inherent in the ownership and operation of real estate and real estate related businesses and assets. These risks include those associated with the burdens of ownership of real property, general and local economic conditions, changes in supply of and demand for competing properties in an area (as a result, for instance, of overbuilding), fluctuations in the average occupancy, the financial resources of tenants, changes in building, environmental and other laws, energy and supply shortages, various uninsured or uninsurable risks, natural disasters, changes in government regulations (such as rent control), changes in real property tax rates, changes in interest rates, the reduced availability of mortgage funds which may render the sale or refinancing of properties difficult or impracticable, negative developments in the economy that depress travel activity, environmental liabilities, contingent liabilities on disposition of assets, terrorist attacks, war and other factors that are beyond our control. In addition, if we acquire direct or indirect interests in

59

---

Table of Contents

undeveloped land or underdeveloped real property, which may often be non-income producing, they will be subject to the risks normally associated with such assets and development activities, including risks relating to the availability and timely receipt of zoning and other regulatory or environmental approvals, the cost and timely completion of construction (including risks beyond the control of our fund, such as weather or labor conditions or material shortages) and the availability of both construction and permanent financing on favorable terms.

        In addition, investments in real assets may cause adverse tax consequences for certain non-U.S. unitholders regarding income effectively connected with the conduct of a U.S. trade or business and the imposition of certain tax withholding. Please see "—Risks Related to U.S. Taxation—Non-U.S. persons face unique U.S. tax issues from owning our common units that may result in adverse tax consequences to them". Moreover, investments in real assets may also require all our unitholders to file tax returns and pay taxes in various state and local jurisdictions in the U.S. and abroad where these real assets are located. Please see "Risks Related to U.S. Taxation—Holders of our common units may be subject to state, local and foreign taxes and return filing requirements as a result of owning such common units".

Our investment in Nephila is exposed to natural catastrophe and weather risk.

        Our investment in Nephila, an investment manager focused on investing in natural catastrophe and weather risk, is exposed to a risk of reduced revenues resulting from natural disasters. Because catastrophic loss events are by their nature unpredictable, historical results of operations of Nephila may not be indicative of its future results of operations. As a result of the occurrence of one or more major catastrophes in any given period, the expected returns from this investment may fall short of our expectations.

We often pursue investment opportunities that involve business, regulatory, legal or other complexities.

        As an element of our investment style, we often pursue complex investment opportunities. This can often take the form of substantial business, regulatory or legal complexity that would deter other investment managers. Our tolerance for complexity presents risks, as such transactions can be more difficult, expensive and time-consuming to finance and execute; it can be more difficult to manage or realize value from the assets acquired in such transactions; and such transactions sometimes entail a higher level of regulatory scrutiny, the application of complex tax laws or a greater risk of contingent liabilities. We may cause our funds to acquire an investment that is subject to contingent liabilities, which could be unknown to us at the time of acquisition or, if they are known to us, we may not accurately assess or protect against the risks that they present. Acquired contingent liabilities could thus result in unforeseen losses for our funds. In addition, in connection with the disposition of an investment in a portfolio company, a fund may be required to make representations about the business and financial affairs of such portfolio company typical of those made in connection with the sale of a business. A fund may also be required to indemnify the purchasers of such investment to the extent that any such representations are inaccurate. These arrangements may result in the incurrence of contingent liabilities by a fund, even after the disposition of an investment. Any of these risks could harm the performance of our funds.

Our private equity investments are typically among the largest in the industry, which involves certain complexities and risks that are not encountered in small- and medium-sized investments.

        Our private equity funds make investments in companies with relatively large capitalizations, which involves certain complexities and risks that are not encountered in small-and medium-sized investments. For example, larger transactions may be more difficult to finance and exiting larger deals may present incremental challenges. In addition, larger transactions may pose greater challenges in implementing changes in the company's management, culture, finances or operations, and may entail

60

Table of Contents

greater scrutiny by regulators, interest groups and other third parties. These constituencies may be more active in opposing some larger investments by certain private equity firms.

        In some transactions, the amount of equity capital that is required to complete a large capitalization private equity transaction has increased significantly, which has resulted in some of the largest private equity transactions being structured as "consortium transactions." A consortium transaction involves an equity investment in which two or more other private equity firms serve together or collectively as equity sponsors. While we have sought to limit where possible the amount of consortium transactions in which we have been involved, we have participated in a significant number of those transactions. Consortium transactions generally entail a reduced level of control by our firm over the investment because governance rights must be shared with the other consortium investors. Accordingly, we may not be able to control decisions relating to a consortium investment, including decisions relating to the management and operation of the company and the timing and nature of any exit, which could result in the risks described in "—Our funds have made investments in companies that we do not control, exposing us to the risk of decisions made by others with which we may not agree." Any of these factors could increase the risk that our larger investments could be less successful. The consequences to our investment funds of an unsuccessful larger investment could be more severe given the size of the investment.

Our funds and accounts have made investments in companies that we do not control, exposing us to the risk of decisions made by others with which we may not agree.

        Our funds and accounts hold investments that include debt instruments and equity securities of companies that we do not control and such investments may comprise an increasing part of our business. Such instruments and securities may be acquired by our funds and accounts through trading activities or through purchases of securities from the issuer. In addition, our funds and accounts may acquire minority equity interests, particularly when sponsoring investments as part of a large investor consortium, and may also dispose of a portion of their majority equity investments in portfolio companies over time in a manner that results in the funds or accounts retaining a minority investment. Those investments will be subject to the risk that the company in which the investment is made may make business, financial or management decisions with which we do not agree or that the majority stakeholders or the management of the company may take risks or otherwise act in a manner that does not serve our interests. If any of the foregoing were to occur, the value of investments by our funds or accounts could decrease and our financial condition, results of operations and cash flow could be adversely affected. In addition, many of our investments in our Public Markets funds, vehicles and accounts are in companies or other funds that we do not control.

We make investments in companies that are based outside of the United States, which may expose us to additional risks not typically associated with investing in companies that are based in the United States.

        Many of our funds, vehicles and accounts invest or have the flexibility to invest a significant portion of their assets in the equity, debt, loans or other securities of issuers that are based outside of the United States. A substantial amount of these investments consist of private equity investments made by our private equity funds. For example, as of December 31, 2012, approximately 52% of the unrealized value of the investments of those funds and accounts was attributable to foreign investments. Investing in companies that are based in countries outside of the United States and, in particular, in emerging markets such as China, India, Turkey, countries in south and southeast Asia, Latin America and Africa, involves risks and considerations that are not typically associated with investments in companies established in the United States. These risks may include the following:

•

the possibility of exchange control regulations, restrictions on repatriation of profit on investments or of capital invested, political and social instability, nationalization or expropriation of assets;

Table of Contents

•

the imposition of non-U.S. taxes;



•

differences in the legal and regulatory environment, for example the recognition of information barriers, or enhanced legal and regulatory compliance;



•

greater levels of corruption and potential exposure to the FCPA and other laws that prohibit improper payments or offers of payments to foreign governments, their officials and other third parties;



•

violations of sanctions regimes;



•

limitations on borrowings to be used to fund acquisitions or dividends;



•

limitations on permissible counterparties in our transactions or consolidation rules that effectively restrict the types of businesses in which we may invest;



•

political risks generally, including political hostility to investments by foreign or private equity investors;



•

less liquid markets;



•

reliance on a more limited number of commodity inputs, service providers and/or distribution mechanisms;



•

adverse fluctuations in currency exchange rates and costs associated with conversion of investment principal and income from one currency into another;



•

higher rates of inflation;



•

less available current information about an issuer;



•

higher transaction costs;



•

less government supervision of exchanges, brokers and issuers;



•

less developed bankruptcy and other laws;



•

greater application of concepts like equitable subordination, which may, in bankruptcy or insolvency, result in the subordination of debt or other senior interests held by our investment funds, vehicles or accounts in companies in which our investment funds, vehicles or accounts also hold equity interests;



•

difficulty in enforcing contractual obligations;



•

lack of uniform accounting, auditing and financial reporting standards;



•

less stringent requirements relating to fiduciary duties;



•

fewer investor protections; and



•

greater price volatility.

        As a result of the complexity of and lack of clear precedent or authority with respect to the application of various income tax laws to our structures, the application of rules governing how transactions and structures should be reported is also subject to differing interpretations. In particular, certain jurisdictions, including Denmark, France, Germany, and Japan, among others, have either proposed or adopted rules that seek to limit the amount of interest that may be deductible where the lender and the borrower are related parties (or where third party borrowings have been guaranteed by a related party) or may seek to interpret existing rules in a more restrictive manner. In addition, the tax authorities of certain countries, such as Germany, Belgium, France, and Singapore, have sought to disallow tax deductions for transaction and certain other costs at the portfolio company level either on

62

---

Table of Contents

the basis that the entity claiming the deduction does not benefit from the costs incurred or on other grounds. There is also significant risk in Germany that tax losses and interest carry-forwards would lose their value on a change of ownership due to restrictive legislation. These measures will most likely adversely affect portfolio companies in those jurisdictions in which our investment funds and vehicles have investments, and limit the benefits of additional investments in those countries. Our business is also subject to the risk that similar measures might be introduced in other countries in which our investment funds and vehicles currently have investments or plan to invest in the future, or that other legislative or regulatory measures that negatively affect their respective portfolio investments might be promulgated in any of the countries in which they invest.

        In addition, certain countries such as Australia, China, India, Japan and South Korea, where we have made investments, have sought to tax investment gains derived by nonresident investors, including private equity funds, from the disposition of the equity in companies operating in those countries. In some cases this development is the result of new legislation or changes in the interpretation of existing legislation and local authority assertions that investors have a local taxable presence or are holding companies for trading purposes rather than for capital purposes, or are not otherwise entitled to treaty benefits. With respect to India, in 2011 the Supreme Court of India held in favor of a taxpayer finding that the sale of a foreign company that indirectly held Indian assets was not subject to Indian tax. However, the tax laws were amended in 2012 to subject such gains to Indian tax with retroactive effect. Further, a general anti-avoidance rule was also introduced that would provide a basis for the tax authorities to subject other sales and investments through intermediate holding jurisdictions such as Mauritius to Indian tax. While such rule is presently scheduled to become effective for tax years beginning on or after April 1, 2013, the Indian government and finance minister of India have raised concerns about with respect to these new rules including their retroactive effect in certain circumstances. Indian taxation of the capital gains of a foreign investor, upon a direct or indirect sale of an Indian company, remains uncertain.

        Further, the tax authorities in certain countries, such as Australia, Belgium, China, Denmark, Germany, and South Korea have sought to deny the benefits of income tax treaties or EU Directives with respect to withholding taxes on interest and dividends of nonresident entities, on the basis that the entity benefiting from such treaty or Directive is not the owner of the income, is a mere conduit inserted primarily to access treaty benefits or Directives, or otherwise lacks substance.

        As a result of the complexity of our structures, foreign jurisdictions may seek to tax a material portion of the fee income associated with our management advisory activity. Due to the complexity, sophistication, and global nature of our investment decision making function, foreign jurisdictions may assert that a material amount of fee income was associated with a taxable presence in their jurisdiction and assert that such income is subject to local tax, potentially reducing our profits associated with such income, although this risk may be mitigated by the availability of foreign tax credits.

        Although we expect that most of the capital commitments of our funds, vehicles and accounts will be denominated in U.S. dollars, our investments and capital commitments that are denominated in a foreign currency, such as euro, will be subject to the risk that the value of a particular currency will change in relation to one or more other currencies. Among the factors that may affect currency values are trade balances, the ability of countries to pay their national debt, levels of short-term interest rates, differences in relative values of similar assets in different currencies, long-term opportunities for investment and capital appreciation and political developments. We may employ hedging techniques to minimize these risks, but we can offer no assurance that such strategies will be effective or even available at all. If we engage in hedging transactions, we may be exposed to additional risks associated with such transactions. See "—Risk management activities may adversely affect the return on our investments."

Table of Contents

Third party investors in our funds with commitment-based structures may not satisfy their contractual obligation to fund capital calls when requested by us, which could adversely affect a fund's operations and performance.

        Investors in certain of our funds make capital commitments to those funds that the funds are entitled to call from those investors at any time during prescribed periods. We depend on fund investors fulfilling their commitments when we call capital from them in order for such funds to consummate investments and otherwise pay their obligations (for example, management fees) when due. Any fund investor that did not fund a capital call would generally be subject to several possible penalties, including having a significant amount of existing investment forfeited in that fund. However, the impact of the penalty is directly correlated to the amount of capital previously invested by the investor in the fund and if an investor has invested little or no capital, for instance early in the life of the fund, then the forfeiture penalty may not be as meaningful. Investors may in the future also negotiate for lesser or reduced penalties at the outset of the fund, thereby inhibiting our ability to enforce the funding of a capital call. If our fund investors were to fail to satisfy a significant amount of capital calls for any particular fund or funds, the operation and performance of those funds could be materially and adversely affected.

Our equity investments and many of our debt investments often rank junior to investments made by others, exposing us to greater risk of losing our investment.

        In many cases, the companies in which our funds invest have, or are permitted to have, outstanding indebtedness or equity securities that rank senior to our fund's investment. By their terms, such instruments may provide that their holders are entitled to receive payments of distributions, interest or principal on or before the dates on which payments are to be made in respect of our investment. Also, in the event of insolvency, liquidation, dissolution, reorganization or bankruptcy of a company in which an investment is made, holders of securities ranking senior to our investment would typically be entitled to receive payment in full before distributions could be made in respect of its investment. In addition, debt investments made by our investment funds, vehicles or accounts in our portfolio companies may be equitably subordinated to the debt investments made by third parties in our portfolio companies. After repaying senior security holders, the company may not have any remaining assets to use for repaying amounts owed in respect of our investment. To the extent that any assets remain, holders of claims that rank equally with our investment would be entitled to share on an equal and ratable basis in distributions that are made out of those assets. Also, during periods of financial distress or following an insolvency, the ability of our funds to influence a company's affairs and to take actions to protect their investments may be substantially less than that of the senior creditors.

Risk management activities may adversely affect the return on our investments.

        When managing exposure to market risks, we employ hedging strategies or certain forms of derivative instruments to limit our exposure to changes in the relative values of investments that may result from market developments, including changes in prevailing interest rates and currency exchange rates. The scope of risk management activities undertaken by us varies based on the level and volatility of interest rates, prevailing foreign currency exchange rates, the types of investments that are made and other changing market conditions. The use of hedging transactions and other derivative instruments to reduce the effects of a decline in the value of a position does not eliminate the possibility of fluctuations in the value of the position or prevent losses if the value of the position declines. However, such activities can establish other positions designed to gain from those same developments, thereby offsetting the decline in the value of the position. Such transactions may also limit the opportunity for gain if the value of a position increases. Moreover, it may not be possible to limit the exposure to a

64

---

Table of Contents

market development that is so generally anticipated that a hedging or other derivative transaction cannot be entered into at an acceptable price.

        The success of any hedging or other derivative transactions that we enter into generally will depend on our ability to correctly predict market changes. As a result, while we may enter into such transactions in order to reduce our exposure to market risks, unanticipated market changes may result in poorer overall investment performance than if the hedging or other derivative transaction had not been executed. In addition, the degree of correlation between price movements of the instruments used in connection with hedging activities and price movements in a position being hedged may vary. Moreover, for a variety of reasons, we may not seek or be successful in establishing a perfect correlation between the instruments used in hedging or other derivative transactions and the positions being hedged. An imperfect correlation could prevent us from achieving the intended result and could give rise to a loss. In addition, it may not be possible to fully or perfectly limit our exposure against all changes in the value of its investments, because the value of investments is likely to fluctuate as a result of a number of factors, some of which will be beyond our control or ability to hedge.

        The CFTC has proposed or adopted regulations governing swaps and security-based swaps, which may limit our trading activities and our ability to implement effective hedging strategies or increase the costs of compliance. See "Risks Related to Our Business—Extensive regulation of our businesses affects our activities and creates the potential for significant liabilities and penalties. The possibility of increased regulatory focus or legislative or regulatory changes could result in additional burdens on our business."

Certain of our funds may make a limited number of investments, or investments that are concentrated in certain geographic regions or asset types, which could negatively affect their performance to the extent those concentrated investments perform poorly.

        The governing agreements of our funds contain only limited investment restrictions and only limited requirements as to diversification of fund investments, either by geographic region or asset type. Our private equity funds generally permit up to 20% of the fund to be invested in a single company. During periods of difficult market conditions or slowdowns in these sectors or geographic regions, decreased revenues, difficulty in obtaining access to financing and increased funding costs may be exacerbated by this concentration of investments, which would result in lower investment returns. Because a significant portion of a fund's capital may be invested in a single investment or portfolio company, a loss with respect to such investment or portfolio company could have a significant adverse impact on such fund's capital. Accordingly, a lack of diversification on the part of a fund could adversely affect a fund's performance and therefore, our financial condition and results of operations.

Because we hold interests in some of our portfolio companies both through our management of private equity funds as well as through separate investments in those funds and direct co-investments, fluctuation in the fair values of these portfolio companies may have a disproportionate impact on the investment income earned by us.

        We hold interests in some of our portfolio companies through our management of private equity funds in our Private Markets segment, as well as through separate investments in those funds and co-investments in certain portfolio companies of such funds, principally consisting of the assets we acquired from KPE in the KPE Transaction, in our Capital Markets and Principal Activities segment. As of December 31, 2012, we hold significant aggregate investments in each of Alliance Boots GmbH, HCA Inc., The Nielsen Company B.V. and Dollar General Corporation, which each represent more than 5% of our Capital Markets and Principal Activities segment investment balance. As a result of our disproportionate investment in these companies, or any other portfolio companies for which similar investments are held in the future, any fluctuation in the fair values of these portfolio companies may

65

have a disproportionate impact on the investment income earned by us as compared to other portfolio companies.

Our business activities may give rise to a conflict of interest with our funds.

        As we have expanded and as we continue to expand the number and scope of our businesses, we increasingly confront potential conflicts of interest relating to investment activities among our various funds and also our own account. For example,

•

In pursuing the interest of our fund investors, we may take actions that could reduce our AUM or our profits that we could otherwise realize in the short term.



•

We may be required to allocate investment opportunities among investment vehicles that may have overlapping investment objectives, including vehicles that may have different fee structures, and among KKR co-investment vehicles (including vehicles in which KKR employees may investment) and third party co-investors.



•

We may, on behalf of our funds or KKR itself, buy, sell, hold or otherwise deal with securities or other investments that may be purchased, sold or held by our other funds or that are otherwise issued by a portfolio company in which our funds invest. Conflicts of interest may arise between a fund, on one hand, and KKR on the other or among our funds including but not limited to those relating to the purchase or sale of investments, the structuring of, or exercise of rights with respect to investment transactions and the advice we provide to our funds.



•

We may invest on behalf of our fund or for our own account in a portfolio company of one fund that is a competitor, service provider, supplier, customer, or other counterparty with respect to a portfolio company of another fund.



•

A decision to acquire material non-public information about a company while pursuing an investment opportunity for a particular fund or our own account may result in our having to restrict the ability of other funds to take any action.



•

Conflicts may arise in allocating time, services or resources among the investment activities of our funds, KKR, other KKR-affiliated entities and the employees of KKR.



•

The general partner's entitlement to receive carried interest from many of our funds may create an incentive for that general partner to make riskier and more speculative investments on behalf of fund than would be the case in the absence of such an arrangement. In addition, for our funds that pay carried interest based on accrued rather than realized gains, the amount of carried interest to which the general partner is entitled and the timing of its receipt of carried interest will depend on the valuation by the general partner of the fund's investment.



•

From time to time, one of our funds may seek to effect a purchase or sale of an investment with one or more of our other funds in a so-called "cross transaction".



•

The investors in our investment vehicles are based in a wide variety of jurisdictions and take a wide variety of forms, and consequently have diverging interests among themselves from a regulatory, tax or legal perspective or with respect to investment policies and target risk/return profiles.



•

We or our affiliates, including our capital markets business, may receive fees or other compensation in connection with specific transactions or different clients that may give rise to conflicts. The decision to take on an opportunity in one of our businesses may, as a practical matter, also limit the ability of one or our other businesses to take advantage of other related opportunities.

66

Table of Contents

        In addition, our funds and accounts also invest in a broad range of asset classes throughout the corporate capital structure. These investments include investments in corporate loans and debt securities, preferred equity securities and common equity securities. In certain cases, we may manage separate funds or accounts that invest in different parts of the same company's capital structure. For example, our fixed income funds may invest in different classes of the same company's debt and may make debt investments in a company that is owned by one of our private equity funds. In those cases, the interests of our funds and accounts may not always be aligned, which could create actual or potential conflicts of interest or the appearance of such conflicts. For example, one of our private equity funds could have an interest in pursuing an acquisition, divestiture or other transaction that, in its judgment, could enhance the value of the private equity investment, even though the proposed transaction would subject one of our fixed income fund's debt investments to additional or increased risks. Finally, our ability to effectively implement a public securities strategy may be limited to the extent that contractual obligations entered into in the ordinary course of our private equity business impose restrictions on our engaging in transactions that we may be interested in otherwise pursuing.

        We may also cause different investment funds to invest in a single portfolio company, for example where the fund that made an initial investment no longer has capital available to invest. Conflicts may also arise where we make principal investments for our own account or permit employees to invest alongside our investment vehicles or our balance sheet for their own account. In certain cases, we may require that a transaction or investment be approved by fund investors or their advisory committees, be approved by an independent valuation expert, be subject to a fairness opinion, be based on arms-length pricing data or be calculated in accordance with a formula provided for in a fund's governing documents prior to the completion of the relevant transaction to address potential conflicts of interest. Such instances include principal transactions where we or our affiliates warehouse an investment in a portfolio company for the benefit of one or more of our funds or accounts pending the contribution of committed capital by the investors in such funds or accounts, follow-on investments by a fund other than a fund which made an initial investment in a company or transactions in which we arrange for one of our funds or accounts to buy a security from, or sell a security to, another one of our funds or accounts.

        Appropriately dealing with conflicts of interest is complex and difficult and we could suffer reputational damage or potential liability if we fail, or appear to fail, to deal appropriately with conflicts as they arise. Regulatory scrutiny of, or litigation in connection with, conflicts of interest could have a material adverse effect on our reputation which could in turn materially adversely affect our business in a number of ways, including as a result of an inability to raise additional funds and a reluctance of counterparties to do business with us.

If KFN were deemed to be an "investment company" subject to regulation under the Investment Company Act, applicable restrictions could have an adverse effect on our business.

        Our business would be adversely affected if KFN, the publicly traded specialty finance company managed by us, was to be deemed to be an investment company under the Investment Company Act. A person will generally be deemed to be an "investment company" for purposes of the Investment Company Act if, absent an available exception or exemption, it (i) is or holds itself out as being engaged primarily, or proposes to engage primarily, in the business of investing, reinvesting or trading in securities; or (ii) owns or proposes to acquire investment securities having a value exceeding 40% of the value of its total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis. We believe KFN is not and does not propose to be primarily engaged in the business of investing, reinvesting or trading in securities, and we do not believe that KFN has held itself out as such. KFN conducts its operations primarily through its majority-owned subsidiaries, each of which is either outside of the definition of an investment company as defined in the Investment Company Act or excepted from such definition under the Investment Company Act. KFN monitors its

67

---

Table of Contents

holdings regularly to confirm its continued compliance with the 40% test described in clause (ii) above, and restricts its subsidiaries with respect to the assets in which each of them can invest and/or the types of securities each of them may issue in order to ensure conformity with exceptions provided by, and rules and regulations promulgated under, the Investment Company Act. If the SEC were to disagree with KFN's treatment of one or more of its subsidiaries as being excepted from the Investment Company Act, with its determination that one or more of its other holdings are not investment securities for purposes of the 40% test, or with its determinations as to the nature of its business or the manner in which it holds itself out, KFN and/or one or more of its subsidiaries could be required either (i) to change substantially the manner in which it conducts its operations to avoid being subject to the Investment Company Act or (ii) to register as an investment company. Either of these would likely have a material adverse effect on KFN, its ability to service its indebtedness and to make distributions on its shares, and on the market price of its shares and securities, and could thereby materially adversely affect our business, financial condition and results of operations.

        On August 31, 2011 the SEC published an advance notice of proposed rulemaking regarding Rule 3a-7 and a concept release seeking information on Section 3(c)(5)(C), two provisions with which KFN's subsidiaries must comply under the 40% test described above. Among the issues for which the SEC has requested comment is whether Rule 3a-7 should be modified so that parent companies of subsidiaries that rely on Rule 3a-7 should treat their interests in such subsidiaries as investment securities for purposes of the 40% test. The SEC is also seeking information about the nature of entities that invest in mortgages and mortgage-related pools and how the SEC staff's interpretive positions in connection with Section 3(c)(5)(C) affect these entities. Any guidance or action from the SEC or its staff, including changes that the SEC may ultimately propose and adopt to the way Rule 3a-7 applies to entities or new or modified interpretive positions related to Section 3(c)(5)(C), could further inhibit KFN's ability, or the ability of any of its subsidiaries, to pursue its current or future operating strategies, which could have a material adverse effect on KFN and on us.

Investors in certain of our Public Markets funds and vehicles may redeem their investments in these funds with minimal notice.

        On October 1, 2012, KKR completed its acquisition of Prisma, a provider of customized hedge fund solutions, currently principally through fund of funds portfolios. Investors in these funds of funds along with those in our existing long/short equity strategy and similar investment vehicles may generally submit redemptions to redeem their investments on a quarterly basis following the expiration of a specified period of time or in certain cases capital may be withdrawn earlier subject to a fee, in each case subject to the applicable fund's specific redemption provisions. For certain Prisma funds managed as part of a single investor's mandate the length of time to redeem an investment may vary and will depend on the liquidity constraints of each Prisma fund's underlying portfolio. Factors which could result in investors leaving our funds include changes in interest rates that make other investments more attractive, changes in investor perception regarding our focus or alignment of interest, unhappiness with a fund's performance or investment strategy, changes in our reputation, departures or changes in responsibilities of key investment professionals, performance and liquidity needs of fund investors. In a declining market or period of economic disruption or uncertainty, the pace of redemptions and consequent reduction in our AUM could accelerate. The decrease in revenues that would result from significant redemptions from our funds of funds or other similar investment vehicles could have a material adverse effect on our business, revenues, net income and cash flows.

        A portion of assets invested in our fund of hedge funds strategy are managed through separately managed accounts or entities structured for investment by one investor or related investors whereby we earn management and incentive fees, and we intend to continue to seek additional separately managed account or entity mandates. The investment management agreements we enter into in connection with managing separately managed accounts or entities on behalf of certain clients may be terminated by

68

---

Table of Contents

such clients on as little as 30 days' prior written notice, or less in certain prescribed circumstances. In addition, the boards of directors of the certain funds we manage could terminate our advisory engagement of those companies, on as little as 30 days' prior written notice. Similarly, we provide subadvisory services to other investment advisors and managers. Such investment advisors and managers could terminate our subadvisory agreements on as little as 30 days' prior written notice. In the case of any such terminations, the management and incentive fees we earn in connection with managing such account or company would immediately cease, which could result in a significant adverse impact on our revenues.

        A fund of funds is subject to risks related to the limited rights it has to withdraw, transfer or otherwise liquidate its investments from the underlying hedge funds or other funds in which it invests. Hedge funds, including those in which our fund of funds are invested and the hedge funds we offer to our fund investors, may make investments or hold trading positions in markets that are volatile and which may become illiquid. Timely divestiture or sale of trading positions can be impaired by decreased trading volume, increased price volatility, concentrated trading positions, limitations on the ability to transfer positions in highly specialized or structured transactions to which they may be a party, and changes in industry and government regulations. It may be impossible or costly for hedge funds to liquidate positions rapidly in order to meet margin calls, withdrawal requests or otherwise, particularly if there are other market participants seeking to dispose of similar assets at the same time or the relevant market is otherwise moving against a position or in the event of trading halts or daily price movement limits on the market or otherwise. Moreover, these risks may be exacerbated for funds of funds such as those we manage. For example, if one of our funds of funds were to invest a significant portion of its assets in two or more hedge funds that each had illiquid positions in the same issuer, the illiquidity risk for our funds of hedge funds would be compounded. In 2008 many hedge funds experienced significant declines in value. In many cases, these declines in value were both provoked and exacerbated by margin calls and forced selling of assets, often at distressed prices. Moreover, certain of our funds of funds were invested in hedge funds that halted redemptions in the face of illiquidity and other issues, which precluded those funds of funds from receiving their capital back on request. There can be no guarantee that such a situation would not recur, particularly in times of market distress.

        In addition, three funds in our Public Markets business are registered under the 1940 Act as management investment companies. These funds and KKR Asset Management LLC, which serves as their investment adviser, are subject to the 1940 Act and the rules thereunder. One of these funds is an open-end fund. Investors in the open-end fund may generally redeem their investments on a daily basis. Two of these funds are close-end funds. The closed-end funds may, at the discretion of the boards of those funds, offer quarterly repurchases of up to 20 percent of the net assets of the funds. In addition, the management fees we are paid for managing the investment company will generally be subject to contractual rights the company's board of directors (or, in the case of the business development company we manage, the investment adviser) has to terminate our management of an account on as short as 60 days' prior notice. Termination of these agreements would reduce the fees we earn from the relevant funds, which could have a material adverse effect on our results of operations.

Investments by our fund of funds, long/short equity strategy and any other hedge funds and similar investment vehicles are subject to numerous additional risks.

        Investments by one or more hedge funds and investment vehicles with similar characteristics that we currently advise or may organize in the future are subject to numerous additional risks, including the following:

•

Our long/short equity strategy is newly established without any operating history, and we do not have any significant track record as a hedge fund manager.

69

---

Table of Contents

•

Generally, there are few limitations on the execution of investment strategies of a hedge fund or fund of funds, which are subject to the sole discretion of the management company or the general partner of such funds.



•

Hedge funds may engage in short selling, which is subject to the theoretically unlimited risk of loss because there is no limit on how much the price of a security may appreciate before the short position is closed out. A fund may be subject to losses if a security lender demands return of the lent securities and an alternative lending source cannot be found or if the fund is otherwise unable to borrow securities that are necessary to hedge its positions.



•

Hedge funds and investment vehicles with similar characteristics are exposed to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the fund to suffer a loss. Counterparty risk is accentuated for contracts with longer maturities where events may intervene to prevent settlement, or where the fund has concentrated its transactions with a single or small group of counterparties. Generally, hedge funds and investment vehicles with similar characteristics are not restricted from dealing with any particular counterparty or from concentrating any or all of their transactions with one counterparty. Moreover, the fund's internal consideration of the creditworthiness of their counterparties may prove insufficient. The absence of a regulated market to facilitate settlement may increase the potential for losses.



•

Credit risk may arise through a default by one of several large institutions that are dependent on one another to meet their liquidity or operational needs, so that a default by one institution causes a series of defaults by the other institutions. This systemic risk may adversely affect the financial intermediaries (such as clearing agencies, clearing houses, banks, securities firms and exchanges) with which the hedge funds and investment vehicles with similar characteristics interact on a daily basis.



•

The efficacy of investment and trading strategies depend largely on the ability to establish and maintain an overall market position in a combination of financial instruments. A hedge fund's trading orders may not be executed in a timely and efficient manner due to various circumstances, including systems failures or human error. In such event, the funds might only be able to acquire some but not all of the components of the position, or if the overall position were to need adjustment, the funds might not be able to make such adjustment. As a result, the funds would not be able to achieve the market position selected by the management company or general partner of such funds, and might incur a loss in liquidating their position.



•

Hedge funds and funds of funds are subject to risks due to potential illiquidity of assets. Hedge funds and funds of funds may make investments or hold trading positions in markets that are volatile and which may become illiquid. Timely divestiture or sale of trading positions can be impaired by decreased trading volume, increased price volatility, concentrated trading positions, limitations on the ability to transfer positions in highly specialized or structured transactions to which they may be a party, and changes in industry and government regulations. It may be impossible or costly for hedge funds or funds of funds to liquidate positions rapidly in order to meet margin calls, redemption requests or otherwise, particularly if there are other market participants seeking to dispose of similar assets at the same time or the relevant market is otherwise moving against a position or in the event of trading halts or daily price movement limits on the market or otherwise. In addition in a declining market or in the event fund investors otherwise demand greater liquidity, the pace of redemptions could accelerate requiring us to sell assets on unfavorable terms.



•

Hedge fund investments are also subject to risks relating to investments in commodities, futures, options and other derivatives, the prices of which are highly volatile and may be subject to the

70

---

Table of Contents

theoretically unlimited risk of loss in certain circumstances, including if the fund writes a call option. Price movements of commodities, futures and options contracts and payments pursuant to swap agreements are influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary and exchange control programs and policies of governments and national and international political and economic events and policies. The value of futures, options and swap agreements also depends upon the price of the commodities underlying them. In addition, hedge funds' assets are subject to the risk of the failure of any of the exchanges on which their positions trade or of their clearinghouses or counterparties. Most U.S. commodities exchanges limit fluctuations in certain commodity interest prices during a single day by imposing "daily price fluctuation limits" or "daily limits," the existence of which may reduce liquidity or effectively curtail trading in particular markets. Our new fund of hedge fund business may also be subject to and may subject our firm to extensive regulations, including those of the Commodity Futures Trading Commission and the regulations described under "—Risks Related to Our Business—Extensive regulation of our businesses affects our activities and creates the potential for significant liabilities and penalties. The possibility of increased regulatory focus or legislative or regulatory changes could result in additional burdens on our business" in our Annual Report on Form 10-K.

        Our common units commenced trading on the NYSE on July 15, 2010 and we are subject to the reporting requirements of the Exchange Act, and requirements of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act. These requirements place a certain level of strain on our systems and resources. The Exchange Act requires that we file annual, quarterly and current reports with respect to our business and financial condition. The Sarbanes-Oxley Act requires that we maintain effective disclosure controls and procedures and internal controls over financial reporting. In order to maintain and improve the effectiveness of our disclosure controls and procedures, significant resources and management oversight will be required. In addition, sustaining our growth may also continue to require us to commit additional management, operational and financial resources to identify new professionals to join the firm and to maintain appropriate operational and financial systems to adequately support expansion. These activities may divert management's attention from other business concerns, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. We have incurred and will continue to incur additional costs for expenses for compliance with the Sarbanes-Oxley Act and rules of the SEC and the NYSE, hiring additional accounting, legal and administrative personnel, and various other costs related to being a public company.

As a limited partnership, we qualify for some exemptions from the corporate governance and other requirements of the NYSE.

        We are a limited partnership and, as a result, qualify for exceptions from certain corporate governance and other requirements of the rules of the NYSE. Pursuant to these exceptions, limited partnerships may elect, and we have elected, not to comply with certain corporate governance requirements of the NYSE, including the requirements: (i) that the listed company have a nominating and corporate governance committee that is composed entirely of independent directors; and (ii) that the listed company have a compensation committee that is composed entirely of independent directors. In addition, as a limited partnership, we are not required to hold annual unitholder meetings. Accordingly, you do not have the same protections afforded to equity holders of entities that are subject to all of the corporate governance requirements of the NYSE.

Our founders are able to determine the outcome of any matter that may be submitted for a vote of our limited partners.

        As of February 21, 2013, KKR Holdings owns 424,979,965 KKR Group Partnership Units, and our principals generally have sufficient voting power to determine the outcome of those few matters that may be submitted for a vote of the holders of our common units, including a merger or consolidation of our business, a sale of all or substantially all of our assets and amendments to our partnership agreement that may be material to holders of our common units. In addition, our limited partnership agreement contains provisions that enable us to take actions that would materially and adversely affect all holders of our common units or a particular class of holders of common units upon the majority vote of all outstanding voting units, and since more than a majority of our voting units are controlled by KKR Holdings, KKR Holdings has the ability to take actions that could materially and adversely affect the holders of our common units either as a whole or as a particular class.

        The voting rights of holders of our common units are further restricted by provisions in our limited partnership agreement stating that any of our common units held by a person that beneficially owns 20% or more of any class of our common units then outstanding (other than our Managing Partner or its affiliates, or a direct or subsequently approved transferee of our Managing Partner or its affiliates) cannot be voted on any matter. Our limited partnership agreement also contains provisions limiting the ability of the holders of our common units to call meetings, to acquire information about our operations, and to influence the manner or direction of our management. Our limited partnership agreement does not restrict our Managing Partner's ability to take actions that may result in our partnership being treated as an entity taxable as a corporation for U.S. federal (and applicable state) income tax purposes. Furthermore, holders of our common units would not be entitled to dissenters' rights of appraisal under our limited partnership agreement or applicable Delaware law in the event of a merger or consolidation, a sale of substantially all of our assets or any other transaction or event.

Our limited partnership agreement contains provisions that reduce or eliminate duties (including fiduciary duties) of our Managing Partner and limit remedies available to unitholders for actions that might otherwise constitute a breach of duty. It will be difficult for unitholders to successfully challenge a resolution of a conflict of interest by our Managing Partner or by its conflicts committee.

        Our limited partnership agreement contains provisions that require holders of our common units to waive or consent to conduct by our Managing Partner and its affiliates that might otherwise raise issues about compliance with fiduciary duties or applicable law. For example, our limited partnership agreement provides that when our Managing Partner is acting in its individual capacity, as opposed to in its capacity as our Managing Partner, it may act without any fiduciary obligations to holders of our common units, whatsoever. When our Managing Partner, in its capacity as our general partner, or our conflicts committee is permitted to or required to make a decision in its "sole discretion" or "discretion" or that it deems "necessary or appropriate" or "necessary or advisable," then our Managing Partner or the conflicts committee will be entitled to consider only such interests and factors as it desires, including its own interests, and will have no duty or obligation (fiduciary or otherwise) to give any consideration to any interest of or factors affecting us or any holder of our common units and will not be subject to any different standards imposed by our limited partnership agreement, the Delaware Revised Uniform Limited Partnership Act, which is referred to as the Delaware Limited Partnership Act, or under any other law, rule or regulation or in equity. These standards reduce the obligations to which our Managing Partner would otherwise be held. See also "—We are a Delaware limited partnership, and there are provisions in our limited partnership agreement regarding exculpation and indemnification of our officers and directors that differ from the Delaware General Corporation Law (DGCL) in a manner that may be less protective of the interests of our common unitholders."

Table of Contents

        The above modifications of fiduciary duties are expressly permitted by Delaware law. Hence, we and holders of our common units will only have recourse and be able to seek remedies against our Managing Partner if our Managing Partner breaches its obligations pursuant to our limited partnership agreement. Unless our Managing Partner breaches its obligations pursuant to our limited partnership agreement, we and holders of our common units will not have any recourse against our Managing Partner even if our Managing Partner were to act in a manner that was inconsistent with traditional fiduciary duties. Furthermore, even if there has been a breach of the obligations set forth in our limited partnership agreement, our limited partnership agreement provides that our Managing Partner and its officers and directors will not be liable to us or holders of our common units, for errors of judgment or for any acts or omissions unless there has been a final and non-appealable judgment by a court of competent jurisdiction determining that our Managing Partner or its officers and directors acted in bad faith or engaged in fraud or willful misconduct. These provisions are detrimental to the holders of our common units because they restrict the remedies available to unitholders for actions that without such limitations might constitute breaches of duty including fiduciary duties.

        Whenever a potential conflict of interest exists between us and our Managing Partner, our Managing Partner may resolve such conflict of interest. If our Managing Partner determines that its resolution of the conflict of interest is on terms no less favorable to us than those generally being provided to or available from unrelated third parties or is fair and reasonable to us, taking into account the totality of the relationships between us and our Managing Partner, then it will be presumed that in making this determination, our Managing Partner acted in good faith. A holder of our common units seeking to challenge this resolution of the conflict of interest would bear the burden of overcoming such presumption. This is different from the situation with Delaware corporations, where a conflict resolution by an interested party would be presumed to be unfair and the interested party would have the burden of demonstrating that the resolution was fair.

        Also, if our Managing Partner obtains the approval of the conflicts committee of our Managing Partner, the resolution will be conclusively deemed to be fair and reasonable to us and not a breach by our Managing Partner of any duties it may owe to us or holders of our common units. This is different from the situation with Delaware corporations, where a conflict resolution by a committee consisting solely of independent directors may, in certain circumstances, merely shift the burden of demonstrating unfairness to the plaintiff. If you purchase, receive or otherwise hold a common unit, you will be treated as having consented to the provisions set forth in our limited partnership agreement, including provisions regarding conflicts of interest situations that, in the absence of such provisions, might be considered a breach of fiduciary or other duties under applicable state law. As a result, unitholders will, as a practical matter, not be able to successfully challenge an informed decision by the conflicts committee.

        We have also agreed to indemnify our Managing Partner and any of its affiliates and any member, partner, tax matters partner, officer, director, employee agent, fiduciary or trustee of our partnership, our Managing Partner or any of our affiliates and certain other specified persons, to the fullest extent permitted by law, against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts incurred by our Managing Partner or these other persons. We have agreed to provide this indemnification unless there has been a final and non-appealable judgment by a court of competent jurisdiction determining that these persons acted in bad faith or engaged in fraud or willful misconduct. We have also agreed to provide this indemnification for criminal proceedings.

        Any claims, suits, actions or proceedings concerning the matters described above or any other matter arising out of or relating in any way to the limited partnership agreement may only be brought in the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction thereof, any other court in the State of Delaware with subject matter jurisdiction.

The market price and trading volume of our common units may be volatile, which could result in rapid and substantial losses for our common unitholders.

        The market price of our common units may be highly volatile and could be subject to wide fluctuations. In addition, the trading volume in our common units may fluctuate and cause significant price variations to occur. If the market price of our common units declines significantly, you may be unable to sell your common units at an attractive price, if at all. The market price of our common units may fluctuate or decline significantly in the future. Some of the factors that could negatively affect the price of our common units or result in fluctuations in the price or trading volume of our common units include:

•

variations in our quarterly operating results or distributions, which may be substantial;



•

our policy of taking a long-term perspective on making investment, operational and strategic decisions, which is expected to result in significant and unpredictable variations in our quarterly returns;



•

failure to meet analysts' earnings estimates;



•

publication of research reports about us or the investment management industry or the failure of securities analysts to cover our common units sufficiently;



•

additions or departures of our principals and other key management personnel;



•

adverse market reaction to any indebtedness we may incur or securities we may issue in the future;



•

changes in market valuations of similar companies;



•

speculation in the press or investment community;



•

changes or proposed changes in laws or regulations or differing interpretations thereof affecting our business or enforcement of these laws and regulations, or announcements relating to these matters;



•

a lack of liquidity in the trading of our common units;



•

adverse publicity about the investment management or private equity industry generally or individual scandals, specifically; and



•

general market and economic conditions.

An investment in our common units is not an investment in any of our funds, and the assets and revenues of our funds are not directly available to us.

        Our common units are securities of KKR & Co. L.P. only. While our historical consolidated and combined financial information includes financial information, including assets and revenues, of certain funds on a consolidated basis, and our future financial information will continue to consolidate certain of these funds, such assets and revenues are available to the fund and not to us except to a limited extent through management fees, carried interest or other incentive income, distributions and other proceeds arising from agreements with funds, as discussed in more detail in this report.

Our common unit price may decline due to the large number of common units eligible for future sale, for exchange, and issuable pursuant to our equity incentive plan.

        The market price of our common units could decline as a result of sales of a large number of common units in the market or the perception that such sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell common units in

the future at a time and at a price that we deem appropriate. As of February 21, 2013, we have 260,937,002 common units outstanding, which amount excludes common units beneficially owned by KKR Holdings in the form of KKR Group Partnership Units discussed below and common units available for future issuance under the KKR & Co. L.P. 2010 Equity Incentive Plan, which we refer to as our Equity Incentive Plan.

        As of February 21, 2013, KKR Holdings owns 424,979,965 KKR Group Partnership Units that may be exchanged, on a quarterly basis, for our common units on a one-for-one basis, subject to customary conversion rate adjustments for splits, unit distributions and reclassifications. Except for interests held by our founders and certain interests held by other principals that were vested upon grant, interests in KKR Holdings that are held by our principals are subject to time based vesting or performance based vesting and, following such vesting, additional restrictions in certain cases on exchanges for a period of one or two years. During 2012, 32,136,605 previously unvested units in KKR Holdings vested. The market price of our common units could decline as a result of the exchange or the perception that an exchange may occur of a large number of KKR Group Partnership Units for our common units. These exchanges, or the possibility that these exchanges may occur, also might make it more difficult for holders of our common units to sell our common units in the future at a time and at a price that they deem appropriate.

        In addition, we will continue to issue additional common units pursuant to our Equity Incentive Plan. The total number of common units which may be issued under our Equity Incentive Plan is equivalent to 15% of the number of fully diluted common units outstanding as of the beginning of the year. The amount may be increased each year to the extent that we issue additional equity. In addition, our limited partnership agreement authorizes us to issue an unlimited number of additional partnership securities and options, rights, warrants and appreciation rights relating to partnership securities for the consideration and on the terms and conditions established by our Managing Partner in its sole discretion without the approval of our unitholders, including awards representing our common units under the Equity Incentive Plan. See "Executive Compensation". In accordance with the Delaware Limited Partnership Act and the provisions of our partnership agreement, we may also issue additional partner interests that have designations, preferences, rights, powers and duties that are different from, and may be senior to, those applicable to our common units.

Risks Related to Our Organizational Structure

Potential conflicts of interest may arise among our Managing Partner, our affiliates and us. Our Managing Partner and our affiliates have limited fiduciary duties to us and the holders of KKR Group Partnership Units, which may permit them to favor their own interests to our detriment and that of the holders of KKR Group Partnership Units.

        Our Managing Partner, which is our general partner, will manage the business and affairs of our business, and will be governed by a board of directors that is co-chaired by our founders, who also serve as our Co-Chief Executive Officers. Conflicts of interest may arise among our Managing Partner and its affiliates, on the one hand, and us and our unitholders, on the other hand. As a result of these conflicts, our Managing Partner may favor its own interests and the interests of its affiliates over us and our unitholders. These conflicts include, among others, the following:

•

Our Managing Partner indirectly through its holding of controlling entities determines the amount and timing of the KKR Group Partnership's investments and dispositions, indebtedness, issuances of additional partner interests, tax liabilities and amounts of reserves, each of which can affect the amount of cash that is available for distribution to holders of KKR Group Partnership Units;



•

Our Managing Partner is allowed to take into account the interests of parties other than us in resolving conflicts of interest, which has the effect of limiting its duties, including fiduciary

75

Table of Contents

duties, to us. For example, our affiliates that serve as the general partners of our funds have fiduciary and contractual obligations to our fund investors, and such obligations may cause such affiliates to regularly take actions that might adversely affect our near-term results of operations or cash flow. Our Managing Partner will have no obligation to intervene in, or to notify us of, such actions by such affiliates;

•

Because our principals indirectly hold their KKR Group Partnership Units through entities that are not subject to corporate income taxation and we hold some of the KKR Group Partnership Units through one or more wholly-owned subsidiaries that are taxable as a corporation, conflicts may arise between our principals and us relating to the selection and structuring of investments, declaring distributions and other matters;



•

Our Managing Partner, including its directors and officers, has limited its and their liability and reduced or eliminated its and their duties, including fiduciary duties, under our partnership agreement to the fullest extent permitted by law, while also restricting the remedies available to holders of common units for actions that, without these limitations, might constitute breaches of duty, including fiduciary duties. In addition, we have agreed to indemnify our Managing Partner, including its directors and officers, and our Managing Partner's affiliates to the fullest extent permitted by law, except with respect to conduct involving bad faith, fraud or willful misconduct;



•

Our partnership agreement does not restrict our Managing Partner from paying us or our affiliates for any services rendered, or from entering into additional contractual arrangements with any of these entities on our behalf, so long as the terms of any such additional contractual arrangements are fair and reasonable to us as determined under our partnership agreement. The conflicts committee will be responsible for, among other things, enforcing our rights and those of our unitholders under certain agreements, against KKR Holdings and certain of its subsidiaries and designees, a general partner or limited partner of KKR Holdings, or a person who holds a partnership or equity interest in the foregoing entities;



•

Our Managing Partner determines how much debt we incur and that decision may adversely affect any credit ratings we receive;



•

Our Managing Partner determines which costs incurred by it and its affiliates are reimbursable by us;



•

Other than as set forth in the confidentiality and restrictive covenant agreements, which in certain cases may only be agreements between our principals and KKR Holdings and which may not be enforceable by us or otherwise waived, modified or amended, affiliates of our Managing Partner and existing and former personnel employed by our Managing Partner are not prohibited from engaging in other businesses or activities, including those that might be in direct competition with us;



•

Our Managing Partner controls the enforcement of obligations owed to the KKR Group Partnerships by us and our affiliates; and



•

Our Managing Partner or our Managing Partner conflicts committee decides whether to retain separate counsel, accountants or others to perform services for us.

        See "Certain Relationships and Related Transactions, and Director Independence."

Certain actions by our Managing Partner's board of directors require the approval of the Class A shares of our Managing Partner, all of which are held by our senior principals.

        All of our Managing Partner's outstanding Class A shares are held by our senior principals. Although the affirmative vote of a majority of the directors of our Managing Partner is required for any action to be taken by our Managing Partner's board of directors, certain specified actions approved

76

Table of Contents

by our Managing Partner's board of directors will also require the approval of a majority of the Class A shares of our Managing Partner. These actions consist of the following:

•

the entry into a debt financing arrangement by us in an amount in excess of 10% of our existing long-term indebtedness (other than the entry into certain intercompany debt financing arrangements);



•

the issuance by our partnership or our subsidiaries of any securities that would (i) represent, after such issuance, or upon conversion, exchange or exercise, as the case may be, at least 5% on a fully diluted, as converted, exchanged or exercised basis, of any class of our or their equity securities or (ii) have designations, preferences, rights, priorities or powers that are more favorable than those of KKR Group Partnership Units;



•

the adoption by us of a shareholder rights plan;



•

the amendment of our limited partnership agreement or the limited partnership agreements of the KKR Group Partnerships;



•

the exchange or disposition of all or substantially all of our assets or the assets of any KKR Group Partnership;



•

the merger, sale or other combination of the partnership or any KKR Group Partnership with or into any other person;



•

the transfer, mortgage, pledge, hypothecation or grant of a security interest in all or substantially all of the assets of the KKR Group Partnerships;



•

the appointment or removal of a Chief Executive Officer or a Co-Chief Executive Officer of our Managing Partner or our partnership;



•

the termination of the employment of any of our officers or the officers of any of our subsidiaries or the termination of the association of a partner with any of our subsidiaries, in each case, without cause;



•

the liquidation or dissolution of the partnership, our Managing Partner or any KKR Group Partnership; and



•

the withdrawal, removal or substitution of our Managing Partner as our general partner or any person as the general partner of a KKR Group Partnership, or the transfer of beneficial ownership of all or any part of a general partner interest in our partnership or a KKR Group Partnership to any person other than one of its wholly owned subsidiaries.

In addition, holders representing a majority of the Class A shares of our Managing Partner have the authority to unilaterally appoint our Managing Partner's directors and also have the ability to appoint the officers of our Managing Partner. Messrs. Kravis and Roberts collectively hold Class A shares representing a majority of the total voting power of the outstanding Class A shares. While neither of them acting alone will be able to control the voting of the Class A shares, they will be able to control the voting of such shares if they act together.

Our common unitholders do not elect our Managing Partner or vote on our Managing Partner's directors and have limited ability to influence decisions regarding our business.

        Our common unitholders do not elect our Managing Partner or its board of directors and, unlike the holders of common stock in a corporation, have only limited voting rights on matters affecting our business and therefore limited ability to influence decisions regarding our business. Furthermore, if our common unitholders are dissatisfied with the performance of our Managing Partner, they have no ability to remove our Managing Partner, with or without cause.

The control of our Managing Partner may be transferred to a third party without our consent.

        Our Managing Partner may transfer its general partner interest to a third party in a merger or consolidation or in a transfer of all or substantially all of its assets without our consent or the consent of our common unitholders. Furthermore, the members of our Managing Partner may sell or transfer all or part of their limited liability company interests in our Managing Partner without our approval, subject to certain restrictions. A new general partner may not be willing or able to form new funds and could form funds that have investment objectives and governing terms that differ materially from those of our current funds. A new owner could also have a different investment philosophy, employ investment professionals who are less experienced, be unsuccessful in identifying investment opportunities or have a track record that is not as successful as our track record. If any of the foregoing were to occur, we could experience difficulty in making new investments, and the value of our existing investments, our business, our results of operations and our financial condition could materially suffer.

We intend to pay periodic distributions to the holders of our common units, but our ability to do so may be limited by our holding company structure and contractual restrictions.

        We intend to pay cash distributions on a quarterly basis. We are a holding company and have no material assets other than the KKR Group Partnership Units that we hold through wholly-owned subsidiaries and have no independent means of generating income. Accordingly, we intend to cause the KKR Group Partnerships to make distributions on the KKR Group Partnership Units, including KKR Group Partnership Units that we directly or indirectly hold, in order to provide us with sufficient amounts to fund distributions we may declare. If the KKR Group Partnerships make such distributions, other holders of KKR Group Partnership Units, including KKR Holdings, will be entitled to receive equivalent distributions pro rata based on their KKR Group Partnership Units.

        The declaration and payment of any future distributions will be at the sole discretion of our Managing Partner, which may change our distribution policy at any time. Our Managing Partner will take into account general economic and business conditions, our strategic plans and prospects, our business and investment opportunities, our financial condition and operating results, compensation expense, working capital requirements and anticipated cash needs, debt and contractual restrictions and obligations (including payment obligations pursuant to the tax receivable agreement), legal, tax and regulatory restrictions, restrictions or other implications on the payment of distributions by us to the holders of KKR Group Partnership Units or by our subsidiaries to us and such other factors as our Managing Partner may deem relevant. Under the Delaware Limited Partnership Act, we may not make a distribution to a partner if after the distribution all our liabilities, other than liabilities to partners on account of their partnership interests and liabilities for which the recourse of creditors is limited to specific property of the partnership, would exceed the fair value of our assets. If we were to make such an impermissible distribution, any limited partner who received a distribution and knew at the time of the distribution that the distribution was in violation of the Delaware Limited Partnership Act would be liable to us for the amount of the distribution for three years. Furthermore, by paying cash distributions rather than investing that cash in our businesses, we risk slowing the pace of our growth, or not having a sufficient amount of cash to fund our operations, new investments or unanticipated capital expenditures, should the need arise.

        Our ability to characterize such distributions as capital gains or qualified dividend income may be limited, and you should expect that some or all of such distributions may be regarded as ordinary income.

We will be required to pay our principals for most of the benefits relating to any additional tax depreciation or amortization deductions we may claim as a result of the tax basis step-up we receive in connection with subsequent exchanges of our common units and related transactions.

        We and one or more of our intermediate holding companies are required to acquire KKR Group Partnership Units from time to time pursuant to our exchange agreement with KKR Holdings. To the extent this occurs, the exchanges are expected to result in an increase in one of our intermediate holding company's share of the tax basis of the tangible and intangible assets of KKR Management Holdings L.P., primarily attributable to a portion of the goodwill inherent in our business, that would not otherwise have been available. This increase in tax basis may increase (for tax purposes) depreciation and amortization and therefore reduce the amount of income tax our intermediate holding companies would otherwise be required to pay in the future. This increase in tax basis may also decrease gain (or increase loss) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets.

        We are party to a tax receivable agreement with KKR Holdings requiring our intermediate holding company to pay to KKR Holdings or transferees of its KKR Group Partnership Units 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax that the intermediate holding companies actually realize as a result of this increase in tax basis, as well as 85% of the amount of any such savings the intermediate holding companies actually realize as a result of increases in tax basis that arise due to future payments under the agreement. A termination of the agreement or a change of control could give rise to similar payments based on tax savings that we would be deemed to realize in connection with such events. This payment obligation will be an obligation of our intermediate holding companies and not of either KKR Group Partnership. In the event that any of our current or future subsidiaries become taxable as corporations and acquire KKR Group Partnership Units in the future, or if we become taxable as a corporation for U.S. federal income tax purposes, we expect that each such entity will become subject to a tax receivable agreement with substantially similar terms. While the actual increase in tax basis, as well as the amount and timing of any payments under this agreement, will vary depending upon a number of factors, including the timing of exchanges, the price of our common units at the time of the exchange, the extent to which such exchanges are taxable and the amount and timing of our taxable income, we expect that as a result of the size of the increases in the tax basis of the tangible and intangible assets of the KKR Group Partnerships, the payments that we may be required to make to our existing owners will be substantial. The payments under the tax receivable agreement are not conditioned upon our existing owners' continued ownership of us. We may need to incur debt to finance payments under the tax receivable agreement to the extent our cash resources are insufficient to meet our obligations under the tax receivable agreement as a result of timing discrepancies or otherwise. In particular, our intermediate holding companies' obligations under the tax receivable agreement would be effectively accelerated in the event of an early termination of the tax receivable agreement by our intermediate holding companies or in the event of certain mergers, asset sales and other forms of business combinations or other changes of control. In these situations, our obligations under the tax receivable agreement could have a substantial negative impact on our liquidity.

        Payments under the tax receivable agreement will be based upon the tax reporting positions that our Managing Partner will determine. We are not aware of any issue that would cause the IRS to challenge a tax basis increase. However, neither KKR Holdings nor its transferees will reimburse us for any payments previously made under the tax receivable agreement if such tax basis increase, or the tax benefits we claim arising from such increase, is successfully challenged by the IRS. As a result, in certain circumstances, payments to KKR Holdings or its transferees under the tax receivable agreement could be in excess of the intermediate holding companies' cash tax savings. The intermediate holding companies' ability to achieve benefits from any tax basis increase, and the payments to be made under

79

Table of Contents

this agreement, will depend upon a number of factors, as discussed above, including the timing and amount of our future income.

If we were deemed to be an "investment company" subject to regulation under the Investment Company Act, applicable restrictions could make it impractical for us to continue our business as contemplated and could have a material adverse effect on our business.

        A person will generally be deemed to be an "investment company" for purposes of the Investment Company Act if:

•

it is or holds itself out as being engaged primarily, or proposes to engage primarily, in the business of investing, reinvesting or trading in securities; or



•

absent an applicable exemption, it owns or proposes to acquire investment securities having a value exceeding 40% of the value of our total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis.

        We believe that we are engaged primarily in the business of providing investment management services and not in the business of investing, reinvesting or trading in securities. We regard ourselves as an investment management firm and do not propose to engage primarily in the business of investing, reinvesting or trading in securities. Accordingly, we do not believe that we are an "orthodox" investment company as defined in Section 3(a)(1)(A) of the Investment Company Act and described in the first bullet point above.

        With regard to the provision described in the second bullet point above, we have no material assets other than our equity interests in subsidiaries, which in turn have no material assets other than equity interests, directly or indirectly, in the KKR Group Partnerships. Through these interests, we indirectly are the sole general partners of the KKR Group Partnerships and indirectly are vested with all management and control over the KKR Group Partnerships. We do not believe our equity interests in our subsidiaries are investment securities, and we believe that the capital interests of the general partners of our funds in their respective funds are neither securities nor investment securities. Accordingly, based on our determination, less than 40% of the partnership's total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis are comprised of assets that could be considered investment securities. In this regard, as a result of the KPE Transaction, we succeeded to a significant number of investment securities previously held by KPE and now held by our KKR Group Partnerships. In addition, we expect to make investments in other investment securities from time to time. We monitor these holdings regularly to confirm our continued compliance with the 40% test described in the second bullet point above. The need to comply with this 40% test may cause us to restrict our business and subsidiaries with respect to the assets in which we can invest and/or the types of securities we may issue, sell investment securities, including on unfavorable terms, acquire assets or businesses that could change the nature of our business or potentially take other actions which may be viewed as adverse by the holders of our common units, in order to ensure conformity with exceptions provided by, and rules and regulations promulgated under, the Investment Company Act.

        The Investment Company Act and the rules thereunder contain detailed parameters for the organization and operation of investment companies. Among other things, the Investment Company Act and the rules thereunder limit or prohibit transactions with affiliates, impose limitations on the issuance of debt and equity securities, generally prohibit the issuance of options and impose certain governance requirements. We intend to conduct our operations so that we will not be deemed to be an investment company under the Investment Company Act. If anything were to happen which would cause the partnership to be deemed to be an investment company under the Investment Company Act, requirements imposed by the Investment Company Act, including limitations on our capital structure, ability to transact business with affiliates (including us) and ability to compensate key employees, would

80

Table of Contents

make it impractical for us to continue our business as currently conducted, impair the agreements and arrangements between and among the partnership, the KKR Group Partnerships and KKR Holdings, or any combination thereof, and materially adversely affect our business, financial condition and results of operations. In addition, we may be required to limit the amount of investments that we make as a principal, potentially divest assets acquired in the KPE Transaction or otherwise conduct our business in a manner that does not subject it to the registration and other requirements of the Investment Company Act.

We are a Delaware limited partnership, and there are certain provisions in our limited partnership agreement regarding exculpation and indemnification of our officers and directors that differ from the Delaware General Corporation Law (DGCL) in a manner that may be less protective of the interests of our common unitholders.

        Our limited partnership agreement provides that to the fullest extent permitted by applicable law our directors or officers will not be liable to us. However, under the DGCL, a director or officer would be liable to us for (i) breach of duty of loyalty to us or our shareholders, (ii) intentional misconduct or knowing violations of the law that are not done in good faith, (iii) improper redemption of shares or declaration of dividend, or (iv) a transaction from which the director derived an improper personal benefit. In addition, our limited partnership agreement provides that we indemnify our directors and officers for acts or omissions to the fullest extent provided by law. However, under the DGCL, a corporation can only indemnify directors and officers for acts or omissions if the director or officer acted in good faith, in a manner he reasonably believed to be in the best interests of the corporation, and, in criminal action, if the officer or director had no reasonable cause to believe his conduct was unlawful. Accordingly, our limited partnership agreement may be less protective of the interests of our common unitholders, when compared to the DGCL, insofar as it relates to the exculpation and indemnification of our officers and directors. See also "—Our limited partnership agreement contains provisions that reduce or eliminate duties (including fiduciary duties) of our limited partner and limit remedies available for unitholders for actions that might otherwise constitute a breach of duty. It will be difficult for unitholders to successfully challenge a resolution of a conflict of interest by our Managing Partner or by its conflicts committee."

Risks Related to U.S. Taxation

If we were treated as a corporation for U.S. federal income tax or state tax purposes, then our distributions to you would be substantially reduced and the value of our common units could be adversely affected.

        The value of your investment in us depends in part on our being treated as a partnership for U.S. federal income tax purposes, which requires that 90% or more of our gross income for every taxable year consist of qualifying income, as defined in Section 7704 of the Internal Revenue Code, and that our partnership not be registered under the Investment Company Act. Qualifying income generally includes dividends, interest, capital gains from the sale or other disposition of stocks and securities and certain other forms of investment income. We intend to structure our investments so as to satisfy these requirements, including by generally holding investments that generate non-qualifying income through one or more subsidiaries that are treated as corporations for U.S. federal income tax purposes. Nonetheless, we may not meet these requirements, may not correctly identify investments that should be owned through corporate subsidiaries, or current law may change so as to cause, in any of these events, us to be treated as a corporation for U.S. federal income tax purposes or otherwise subject us to U.S. federal income tax. We have not requested, and do not plan to request, a ruling from the IRS, on this or any other matter affecting us.

        If we were treated as a corporation for U.S. federal income tax purposes, we would pay U.S. federal, state and local income tax on our taxable income at the applicable tax rates. Distributions to you would generally be taxed again as corporate distributions, and no income, gains, losses, deductions

or credits would otherwise flow through to you. Because a tax would be imposed upon us as a corporation, our distributions to you would be substantially reduced which could cause a reduction in the value of our common units.

        Current law may change, causing us to be treated as a corporation for U.S. federal or state income tax purposes or otherwise subjecting us to entity level taxation. See "—Risks Related to Our Business—The U.S. Congress has considered legislation that would have (i) in some cases after a ten-year period, precluded us from qualifying as a partnership or required us to hold carried interest through taxable subsidiary corporations and (ii) taxed certain income and gains at increased rates. If any similar legislation were to be enacted and apply to us, the after tax income and gain related to our business, as well as the market price of our units, could be reduced." Several states are evaluating ways to subject partnerships to entity level taxation through the imposition of state income, franchise or other forms of taxation. If any state were to impose a tax upon us as an entity, our distributions to you would be reduced.

You will be subject to U.S. federal income tax on your share of our taxable income, regardless of whether you receive any cash distributions, and may recognize income in excess of cash distributions.

        As long as 90% of our gross income for each taxable year constitutes qualifying income as defined in Section 7704 of the Internal Revenue Code and we are not required to register as an investment company under the Investment Company Act on a continuing basis, and assuming there is no change in law, we will be treated, for U.S. federal income tax purposes, as a partnership and not as an association or a publicly traded partnership taxable as a corporation. As a result, a U.S. unitholder will be subject to U.S. federal, state, local and possibly, in some cases, foreign income taxation on its allocable share of our items of income, gain, loss, deduction and credit (including its allocable share of those items of any entity in which we invest that is treated as a partnership or is otherwise subject to tax on a flow through basis) for each of our taxable years ending with or within the unitholder's taxable year, regardless of whether or when such unitholder receives cash distributions. See "—Risks Related to Our Business—The U.S. Congress has considered legislation that would have (i) in some cases after a ten-year period, precluded us from qualifying as a partnership or required us to hold carried interest through taxable subsidiary corporations and (ii) taxed certain income and gains at increased rates. If any similar legislation were to be enacted and apply to us, the after tax income and gain related to our business, as well as the market price of our units, could be reduced."

        You may not receive cash distributions equal to your allocable share of our net taxable income or even the tax liability that results from that income. In addition, certain of our holdings, including holdings, if any, in a controlled foreign corporation, or a CFC, a passive foreign investment company, or a PFIC, or entities treated as partnerships for U.S. federal income tax purposes, may produce taxable income prior to the receipt of cash relating to such income, and holders of our common units that are U.S. taxpayers may be required to take such income into account in determining their taxable income. In the event of an inadvertent termination of the partnership status for which the IRS has granted limited relief, each holder of our common units may be obligated to make such adjustments as the IRS may require to maintain our status as a partnership. Such adjustments may require the holders of our common units to recognize additional amounts in income during the years in which they hold such units. In addition, because of our methods of allocating income and gain among holders of our common units, you may be taxed on amounts that accrued economically before you became a unitholder. For example, phantom income from the portfolio or due to operational activities may arise during a month and be allocated to you, creating taxable liability that KKR would not consider in a quarterly distribution because KKR typically considers tax distributions on an annual basis. Consequently, you may recognize taxable income without receiving any cash.

        Although we expect that distributions we make should be sufficient to cover a holder's tax liability in any given year that is attributable to its investment in us, no assurances can be made that this will be

82

Table of Contents

the case. We will be under no obligation to make any such distribution and, in certain circumstances, may not be able to make any distributions or will only be able to make distributions in amounts less than a holder's tax liability attributable to its investment in us. In addition, we anticipate making quarterly distributions and typically consider tax distributions on an annual basis but allocate taxable income on a monthly basis. As a result, if you dispose of your common units, you may be allocated taxable income during the time you held your common units without receiving any cash distributions corresponding to that period. Accordingly, each holder should ensure that it has sufficient cash flow from other sources to pay all tax liabilities.

Our interests in certain of our businesses will be held through intermediate holding companies, which will be treated as corporations for U.S. federal income tax purposes; such corporations will be liable for significant taxes and may create other adverse tax consequences, which could potentially adversely affect the value of our common units.

        In light of the publicly traded partnership rules under U.S. federal income tax laws and other requirements, we will hold our interest in certain of our businesses through intermediate holding companies, which will be treated as corporations for U.S. federal income tax purposes. These intermediate holding companies will be liable for U.S. federal income taxes at regular rates on all of their taxable income as well as applicable state, local and other taxes. These taxes would reduce the amount of distributions available to be made on our common units. In addition, these taxes could be increased if the IRS were to successfully reallocate deductions or income of the related entities conducting our business.

Changes in U.S. tax law could adversely affect our ability to raise funds from certain foreign investors.

        Under the U.S. Foreign Account Tax Compliance Act, or FATCA, U.S. withholding agents and all entities in a broadly defined class of foreign financial institutions, or FFIs, are required to comply with a complicated and expansive reporting regime or, beginning in 2014, be subject to a 30% United States withholding tax on certain U.S. payments (and beginning in 2017, a 30% withholding tax on gross proceeds from the sale of U.S. stocks and securities) and non-U.S. entities which are not FFIs are required to either certify they have no substantial U.S. beneficial ownership or to report certain information with respect to their substantial U.S. beneficial ownership or, beginning in 2014, be subject to a 30% U.S. withholding tax on certain U.S. payments (and beginning in 2017, a 30% withholding tax on gross proceeds from the sale of U.S. stocks and securities). The reporting obligations imposed under FATCA require FFIs to enter into agreements with the IRS to obtain and disclose information about certain fund investors to the IRS. In addition, the administrative and economic costs of compliance with FATCA may discourage some foreign investors from investing in U.S. funds, which could adversely affect our ability to raise funds from these investors.

Complying with certain tax-related requirements may cause us to invest through foreign or domestic corporations subject to corporate income tax or enter into acquisitions, borrowings, financings or arrangements we may not have otherwise entered into.

        In order for us to be treated as a partnership for U.S. federal income tax purposes and not as an association or publicly traded partnership taxable as a corporation, we must meet the qualifying income exception discussed above on a continuing basis and we must not be required to register as an investment company under the Investment Company Act. In order to effect such treatment, we or our subsidiaries may be required to invest through foreign or domestic corporations subject to corporate income tax, or enter into acquisitions, borrowings, financings or other transactions we may not have otherwise entered into.

Table of Contents

We may hold or acquire certain investments through an entity classified as a PFIC or CFC for U.S. federal income tax purposes.

        Certain of our investments may be in foreign corporations or may be acquired through a foreign subsidiary that would be classified as a corporation for U.S. federal income tax purposes. Such an entity may be PFIC for U.S. federal income tax purposes. In addition, we may hold certain investments in foreign corporations that are treated as CFCs. Unitholders may experience adverse U.S. tax consequences as a result of holding an indirect interest in a PFIC or CFC. These investments may produce taxable income prior to the receipt of cash relating to such income, and unitholders that are U.S. taxpayers will be required to take such income into account in determining their gross income subject to tax. In addition, all or a portion of gain on the sale of a CFC may be taxable at ordinary income rates. Further, with respect to gain on the sale of and excess distributions from a PFIC for which an election for current inclusions is not made, such income would be taxable at ordinary income rates and be subject to an additional tax charge equivalent to an interest charge on the deferral of income inclusions from that PFIC.

Tax gain or loss on disposition of our common units could be more or less than expected.

        If you sell your common units, you will recognize a gain or loss equal to the difference between the amount realized and your adjusted tax basis allocated to those common units. Prior distributions to you in excess of the total net taxable income allocated to you will have decreased the tax basis in your common units. Therefore, such excess distributions will increase your taxable gain, or decrease your taxable loss, when the common units are sold and may result in a taxable gain even if the sale price is less than the original cost. A portion of the amount realized, whether or not representing gain, may be ordinary income to you.

Unitholders may be allocated taxable gain on the disposition of certain assets, even if they did not share in the economic appreciation inherent in such assets.

        We and our intermediate holding companies will be allocated taxable gains and losses recognized by the KKR Group Partnerships based upon our percentage ownership in each KKR Group Partnership. Our share of such taxable gains and losses generally will be allocated pro rata to our unitholders. In some circumstances, under the U.S. federal income tax rules affecting partners and partnerships, the taxable gain or loss allocated to a unitholder may not correspond to that unitholder's share of the economic appreciation or depreciation in the particular asset. This is primarily an issue of the timing of the payment of tax, rather than a net increase in tax liability, because the gain or loss allocation would generally be expected to be offset as a unitholder sold units.

Non-U.S. persons face unique U.S. tax issues from owning our common units that may result in adverse tax consequences to them.

        We expect that we will be engaged in a U.S. trade or business for U.S. federal income tax purposes, including by reason of investments in U.S. real property holding corporations, real estate assets and natural resource and oil and gas investments, in which case some portion of our income would be treated as effectively connected income with respect to non-U.S. holders, or ECI. To the extent our income is treated as ECI, non-U.S. unitholders generally would be subject to withholding tax on their allocable share of such income, would be required to file a U.S. federal income tax return for such year reporting their allocable share of income effectively connected with such trade or business and any other income treated as ECI, and would be subject to U.S. federal income tax at regular U.S. tax rates on any such income (state and local income taxes and filings may also apply in that event). Non-U.S. unitholders that are corporations may also be subject to a 30% branch profits tax (potentially reduced under an applicable treaty) on their actual or deemed distributions of such income. In addition, distributions to non-U.S. unitholders that are attributable to profits on the sale of a U.S. real

84

Table of Contents

property interest may also be subject to 30% withholding tax. Also, non-U.S. unitholders may be subject to 30% withholding on allocations of our income that are U.S. source fixed or determinable annual or periodic income under the Internal Revenue Code, unless an exemption from or a reduced rate of such withholding applies (under an applicable treaty of the Internal Revenue Code) and certain tax status information is provided.

Tax-exempt entities face unique tax issues from owning common units that may result in adverse tax consequences to them.

        Generally, a tax-exempt partner of a partnership would be treated as earning unrelated business taxable income, or UBTI, if the partnership regularly engages in a trade or business that is unrelated to the exempt function of the tax-exempt partner, if the partnership derives income from debt-financed property or if the partner interest itself is debt-financed. As a result of our ownership of real assets and incurrence of acquisition indebtedness we will derive income that constitutes UBTI. Consequently, a holder of common units that is a tax-exempt entity (including an individual retirement account, or IRA, or a 401(k) plan participant) will likely be subject to unrelated business income tax to the extent that its allocable share of our income consists of UBTI. In addition, a tax-exempt investor may be subject to unrelated business income tax on a sale of their common units.

We cannot match transferors and transferees of common units, and we will therefore adopt certain income tax accounting conventions that may not conform with all aspects of applicable tax requirements. The IRS may challenge this treatment, which could adversely affect the value of our common units.

        Because we cannot match transferors and transferees of common units, we have adopted depreciation, amortization and other tax accounting positions that may not conform with all aspects of existing Treasury regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits available to our unitholders. It also could affect the timing of these tax benefits or the amount of gain on the sale of common units and could have a negative impact on the value of our common units or result in audits of and adjustments to our unitholders' tax returns.

        In addition, our taxable income and losses are determined and apportioned among unitholders using conventions we regard as consistent with applicable law. As a result, if you transfer your common units, you may be allocated income, gain, loss and deduction realized by us after the date of transfer. Similarly, a transferee may be allocated income, gain, loss and deduction realized by us prior to the date of the transferee's acquisition of our common units. A transferee may also bear the cost of withholding tax imposed with respect to income allocated to a transferor through a reduction in the cash distributed to the transferee.

The sale or exchange of 50% or more of our capital and profit interests will result in the termination of our partnership for U.S. federal income tax purposes.

        We will be considered to have been terminated for U.S. federal income tax purposes if there is a sale or exchange of 50% or more of the total interests in our capital and profits within a 12-month period. A termination of our partnership would, among other things, result in the closing of our taxable year for all unitholders.

Holders of our common units may be subject to state, local and foreign taxes and return filing requirements as a result of owning such units.

        In addition to U.S. federal income taxes, holders of our common units may be subject to other taxes, including state, local and foreign taxes, unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we do business or own property now or in the future, even if the holders of our common units do not reside in any of those

85

---

Table of Contents

jurisdictions. Holders of our common units may be required to file state and local income tax returns and pay state and local income taxes in some or all of these jurisdictions in the U.S. and abroad. Further, holders of our common units may be subject to penalties for failure to comply with those requirements. It is the responsibility of each unitholder to file all U.S. federal, state, local and foreign tax returns that may be required of such unitholder. In addition our investments in real assets may expose unitholders to additional adverse tax consequences. See "—Our investments in real assets such as real estate and natural resources may expose us to increased risks and liabilities and may expose our unitholders to adverse tax consequences."

Certain U.S. holders of common units are subject to additional tax on "net investment income".

        U.S. holders that are individuals, estates or trusts are subject to a Medicare tax of 3.8% on "net investment income" (or undistributed "net investment income," in the case of estates and trusts) for each taxable year, with such tax applying to the lesser of such income or the excess of such person's adjusted gross income (with certain adjustments) over a specified amount. Net investment income includes net income from interest, dividends, annuities, royalties and rents and net gain attributable to the disposition of investment property. It is anticipated that net income and gain attributable to an investment in our common units will be included in a U.S. holder's "net investment income" subject to this Medicare tax.

We may not be able to furnish to each unitholder specific tax information within 90 days after the close of each calendar year, which means that holders of common units who are U.S. taxpayers should anticipate the need to file annually a request for an extension of the due date of their income tax return.

        As a publicly traded partnership, our operating results, including distributions of income, dividends, gains, losses or deductions, and adjustments to carrying basis, will be reported on Schedule K-1 and distributed to each unitholder annually. It may require longer than 90 days after the end of our fiscal year to obtain the requisite information from all lower-tier entities so that Schedule K-1s may be prepared for the unitholders. For this reason, holders of common units who are U.S. taxpayers should anticipate the need to file annually with the IRS (and certain states) a request for an extension past April 15 or the otherwise applicable due date of their income tax return for the taxable year.

ITEM 5.    MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES.

        Our common units representing limited partner interests began trading on the New York Stock Exchange ("NYSE") on July 15, 2010 and are traded under the symbol "KKR." The following table sets forth the high and low intra-day sales prices per unit of our common units, for the periods indicated, as reported by the NYSE.

        The number of holders of record of our common units as of February 21, 2013 was thirteen. This does not include the number of unitholders that hold shares in "street-name" through banks or broker-dealers.

Distribution Policy

        The following table presents the distributions paid to holders of our common units at the close of business on the specified record date during fiscal 2011 and 2012:

        We have declared a distribution of $0.70 per common unit payable on March 5, 2013 to unitholders of record as of the close of business on February 19, 2013.

        KKR intends to make quarterly cash distributions in amounts that in the aggregate are expected to constitute substantially all of the cash earnings of its investment management business each year in excess of amounts determined by KKR to be necessary or appropriate to provide for the conduct of its business, to make appropriate investments in its business and its investment funds and to comply with applicable law and any of its debt instruments or other agreements. KKR does not intend to distribute net realized principal investment income, other than certain additional distributions that KKR may determine to make. These additional distributions, if any, are intended to cover certain tax liabilities, as calculated by KKR. When KKR & Co. L.P. receives distributions from the KKR Group Partnerships (the holding companies of the KKR business), KKR Holdings receives its pro rata share of such distributions from the KKR Group Partnerships. For purposes of KKR's distribution policy, its distributions are expected to consist of (i) FRE, (ii) carry distributions received from KKR's investment funds which have not been allocated as part of its carry pool, and (iii) any additional distributions for certain taxes as described above. This amount is expected to be reduced by (i) corporate and applicable

87

---

Table of Contents

local taxes, if any, (ii) non-controlling interests, and (iii) amounts determined by KKR to be necessary or appropriate for the conduct of its business and other matters as discussed above.

        Our distribution policy reflects our belief that distributing substantially all of the cash earnings of our investment management business will provide transparency for holders of our common units and impose on us an investment discipline with respect to the businesses and strategies that we pursue.

        Because we make our investment in our business through a holding company structure and the applicable holding companies do not own any material cash-generating assets other than their direct and indirect holdings in KKR Group Partnership Units, distributions are expected to be funded in the following manner:

•

First, the KKR Group Partnerships will make distributions to holders of KKR Group Partnership Units, including the holding companies through which we invest, in proportion to their percentage interests in the KKR Group Partnerships;



•

Second, the holding companies through which we invest will distribute to us the amount of any distributions that they receive from the KKR Group Partnerships, after deducting any applicable taxes, and



•

Third, we will distribute to holders of our units the amount of any distributions that we receive from our holding companies through which we invest.

        The partnership agreements of the KKR Group Partnerships provide for cash distributions, which are referred to as tax distributions, to the partners of such partnerships if we determine that the taxable income of the relevant partnership will give rise to taxable income for its partners. We expect that the KKR Group Partnerships will make tax distributions only to the extent distributions from such partnerships for the relevant year were otherwise insufficient to cover such tax liabilities. Generally, these tax distributions are expected to be computed based on an estimate of the net taxable income of the relevant partnership allocable to a partner multiplied by an assumed tax rate equal to the highest effective marginal combined U.S. federal, state and local income tax rate prescribed for an individual or corporate resident in New York, New York (taking into account the non-deductibility of certain expenses and the character of our income). A portion of any such tax distributions received by us, net of amounts used by our subsidiaries to pay their tax liability, is expected to be distributed by us. Such amounts are generally expected to be sufficient to permit U.S. holders of KKR Group Partnership Units to fund their estimated U.S. tax obligations (including any federal, state and local income taxes) with respect to their distributive shares of net income or gain, after taking into account any withholding tax imposed on us. There can be no assurance that, for any particular holder, such distributions will be sufficient to pay such holder's actual U.S. or non-U.S. tax liability.

        The declaration and payment of any distributions are subject to the discretion of the board of directors of our Managing Partner and the terms of our limited partnership agreement. There can be no assurance that distributions will be made as intended or at all or that such distributions will be sufficient to pay any particular KKR & Co. L.P. unitholder's actual U.S. or non-U.S. tax liability. In particular, the amount and timing of distributions will depend upon a number of factors, including, among others, our available cash and current and anticipated cash needs, including funding of investment commitments and debt service and future debt repayment obligations; general economic and business conditions; our strategic plans and prospects; our results of operations and financial condition; our capital requirements; legal, contractual and regulatory restrictions on the payment of distributions by us or our subsidiaries, including restrictions contained in our debt agreements, and such other factors as the board of directors of our Managing Partner considers relevant. The Managing Partner may change the distribution policy at any time. We are not currently restricted by any contract from making distributions to our unitholders, although certain of our subsidiaries are bound by credit agreements that contain certain restricted payment and/or other covenants, which may have the effect

88

of limiting the amount of distributions that we receive from our subsidiaries. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity—Sources of Cash". In addition, under Section 17-607 of the Delaware Limited Partnership Act, we will not be permitted to make a distribution if, after giving effect to the distribution, our liabilities would exceed the fair value of our assets.

Common Unit Repurchases in the Fourth Quarter of 2012

        No purchases of our common units were made by us or on our behalf in the fourth quarter of the year ended December 31, 2012. During the fourth quarter of 2012, 10,509,230 KKR Group Partnership Units were exchanged by KKR Holdings and our principals for an equal number of our common units, resulting in an increase in our ownership of the KKR Group Partnerships and a corresponding decrease in the ownership of the KKR Group Partnerships by KKR Holdings.

Overview

        Led by Henry Kravis and George Roberts, we are a leading global investment firm with $75.5 billion in AUM as of December 31, 2012 and a 36-year history of leadership, innovation and investment excellence. When our founders started our firm in 1976, they established the principles that guide our business approach today, including a patient and disciplined investment process; the alignment of our interests with those of our fund investors, portfolio companies and other stakeholders; and a focus on attracting world class talent.

        Our business offers a broad range of investment management services to our fund investors and provides capital markets services to our firm, our portfolio companies and other third parties. Throughout our history, we have consistently been a leader in the private equity industry, having completed more than 200 private equity investments with a total transaction value in excess of $470 billion. In recent years, we have grown our firm by expanding our geographical presence and building businesses in new areas, such as fixed income, equity strategies, hedge fund solutions, capital markets, infrastructure, natural resources and real estate. Our new efforts build on our core principles and industry expertise, allowing us to leverage the intellectual capital and synergies in our businesses, and to capitalize on a broader range of the opportunities we source. Additionally, we have increased our focus on servicing our existing fund investors and have increased our investment in developing relationships with new investors in our funds.

        We conduct our business with offices throughout the world, providing us with a pre-eminent global platform for sourcing transactions, raising capital and carrying out capital markets activities. Our growth has been driven by value that we have created through our operationally focused investment approach, the expansion of our existing businesses, our entry into new lines of business, innovation in the products that we offer fund investors, an increased focus on providing tailored solutions to our clients and the integration of capital markets distribution activities.

        As a global investment firm, we earn management, monitoring, transaction and incentive fees for providing investment management, monitoring and other services to our funds, vehicles, managed accounts, specialty finance company and portfolio companies, and we generate transaction-specific income from capital markets transactions. We earn additional investment income from investing our own capital alongside that of our fund investors and from the carried interest we receive from our funds and certain of our other investment vehicles. A carried interest entitles the sponsor of a fund to a specified percentage of investment gains that are generated on third-party capital that is invested.

        We seek to consistently generate attractive investment returns by employing world-class people, following a patient and disciplined investment approach and driving growth and value creation in the assets we manage. Our investment teams have deep industry knowledge and are supported by a substantial and diversified capital base, an integrated global investment platform, the expertise of operating consultants and senior advisors and a worldwide network of business relationships that provide a significant source of investment opportunities, specialized knowledge during due diligence and substantial resources for creating and realizing value for stakeholders. We believe that these aspects of our business will help us continue to expand and grow our business and deliver strong investment performance in a variety of economic and financial conditions.

Business Segments

Private Markets

        Through our Private Markets segment, we manage and sponsor a group of private equity funds and co-investment vehicles that invest capital for long-term appreciation, either through controlling ownership of a company or strategic minority positions. We also manage and source investments in infrastructure, natural resources and real estate. These funds, vehicles and accounts are managed by Kohlberg Kravis Roberts & Co. L.P., an SEC registered investment adviser.

Public Markets

        Through our Public Markets segment, we manage KKR Financials Holdings LLC, or KFN, which is a specialty finance company, as well as a number of investment funds, structured finance vehicles and separately managed accounts that invest capital in (i) leveraged credit strategies, such as leveraged loans and high yield bonds, (ii) liquid long/short equity strategies, (iii) alternative credit strategies such as mezzanine investments, special situations investments and direct senior lending and (iv) hedge fund solutions. Many of these funds, vehicles and accounts, including three management investment companies registered under the Investment Company Act of 1940 (the "1940 Act"), are managed by KKR Asset Management LLC, or KAM, an SEC registered investment adviser. On October 1, 2012 we acquired Prisma Capital Partners LP and its affiliates ("Prisma"), an SEC registered investment adviser, which manages our hedge fund solutions strategies. On January 23, 2013, we acquired a 24.9% interest in Nephila Capital Ltd. ("Nephila"), an investment manager focused on investing in natural catastrophe and weather risk.

Capital Markets and Principal Activities

        Our Capital Markets and Principal Activities segment combines KKR's principal assets with our global capital markets business. Our capital markets business, which includes 30 executives supports our firm, our portfolio companies and select third-party clients by providing tailored capital markets advice and by developing and implementing both traditional and nontraditional capital solutions for investments and companies seeking financing. Our capital markets services include arranging debt and equity financing for transactions, placing and underwriting securities offerings, structuring new investment products and providing capital markets services.

        In addition, through MerchCap Solutions LLC (formerly known as KKR-SPC Merchant Advisors LLC), we seek to provide certain capital markets services to mid-market and sponsor-backed companies as well as principal investments to support client needs.

        KKR's principal assets, which include investments in our investment funds and co-investments in certain portfolio companies of such funds, provide us with a significant source of capital to further grow and expand our business, increase our participation in our existing portfolio of businesses and further align our interests with those of our fund investors and other stakeholders. We believe that the market experience and skills of professionals in our capital markets business and the investment expertise of professionals in our Private Markets and Public Markets segments will allow us to continue to grow and diversify this asset base over time.

Business Environment

        As a global investment firm, we are affected by financial and economic conditions in North America, Europe, Asia-Pacific and elsewhere in the world. Global and regional economic conditions have a substantial impact on our financial condition and results of operations, impacting both the success of the investments we make as well as our ability to exit these investments profitably and to make new investments. The current global economic environment remains uncertain. Europe has experienced negative growth trends as sovereign debt concerns have affected consumer and business behavior which has pushed the region into recession. Fiscal deficits and the levels of government debt in a number of European countries have led to substantial increases in sovereign borrowing costs,

stresses in the European banking system, and associated reductions in the availability of credit and economic activity in the euro area. Ongoing austerity and deleveraging in the developed world are likely to persist in the near-term, which may lead to increased volatility in the global capital markets and pose downside risk to the economic outlook. While a number of policy actions have been taken which seek to address the European sovereign debt crisis, if one or more Eurozone members were to leave the Eurozone, the functioning of Europe's single market currency could be undermined which would cause a deeper and more damaging impact on the global economy. Growth in Asian economies is mixed. For example, the rate of real gross domestic product growth in China has increased modestly, but remains lower compared to the pace of growth in prior years. While low inflation has allowed Chinese authorities to ease monetary conditions, rising commodities prices could cause the central bank in China to tighten monetary policy which could further impair growth. The U.S. economy has grown at a moderate rate in 2012, but key indicators of sustainable growth remain under pressure and for the fourth quarter of 2012 the U.S. economy contracted slightly. For example, while unemployment has declined, the unemployment rate remains elevated and consumer and business spending has been cautious. On March 1, 2013, automatic reductions in U.S. federal government spending are scheduled to take effect. In addition, while the federal debt limit has been temporarily suspended, additional efforts to suspend or increase the debt limit may be required as soon as May 2013. A tightening of U.S. fiscal policy and uncertainty about the resolution of such policy issues may further slow U.S. economic growth and adversely impact the global economy. In light of the weakness in the global economy, sluggish domestic growth and fiscal uncertainty, many of our portfolio companies remain cautious with respect to investments and hiring and have lower expectations for near term growth. Moreover, the level of transaction activity in 2012 generally has slowed with both global and North America merger and acquisition volume declining relative to 2011. While the fourth quarter was our most active investing quarter in 2012, we have experienced a decline in our transaction volume in 2012 relative to 2011. Reduced levels of transaction activity tend to result in a reduced amount of transaction fees and potential future investment gains.

        In addition to economic conditions, global equity markets also have a substantial effect on our financial condition and results of operations, as equity prices, which have been and may continue to be volatile, significantly impact the valuation of our portfolio companies and, therefore, the investment income that we recognize. For our investments that are publicly listed and thus have readily observable market prices, global equity markets have a direct impact on valuation. For other investments, these markets have an indirect impact on valuation as we typically utilize a market multiples valuation approach as one of the methodologies to ascertain fair value of our investments that do not have readily observable market prices. In addition, the receptivity of equity markets to initial public offerings, or IPOs, as well as subsequent equity offerings by companies already public, impacts our ability to realize investment gains. For example in the first quarter of 2013, we were able to complete a secondary sale of common shares of NXP Semiconductors N.V. (NASDAQ: NXPI), HCA, Inc. (NYSE: HCA) and The Nielsen Company B.V. (NYSE: NLSN).

        Notwithstanding the trends described above, global equity markets rose during the year ended December 31, 2012, with the S&P 500 Index up 16.0% and the MSCI World Index up 16.5%. Volatility decreased during the year as evidenced by the Chicago Board Options Exchange Market Volatility Index, or the VIX, a measure of volatility, beginning the year at 23.0 and ending at 18.0 on December 31, 2012. The below-investment grade credit markets also appreciated, with the S&P/LSTA Leveraged Loan Index and the BofA Merrill Lynch High Yield Master II Index increasing 9.7% and 15.6% during the year ended December 31, 2012, respectively.

        Conditions in global credit markets also have a substantial effect on our financial condition and results of operations. We rely on the ability of our funds to obtain committed debt financing on favorable terms in order to complete new private equity transactions. Similarly, our portfolio companies regularly require access to the global credit markets in order to obtain financing for their operations and to refinance or extend the maturities of their outstanding indebtedness. To the extent that conditions in the credit markets render such financing difficult to obtain or more expensive, this may

negatively impact the operating performance and valuations of those portfolio companies and, therefore, our investment returns on our funds. In addition, during economic downturns or periods of slow economic growth, the inability to refinance or extend the maturities of portfolio company debt (and thereby extend our investment holding period) may hinder our ability to realize investment gains from these portfolio companies when economic conditions improve. Credit markets can also impact valuations. For example, we typically use a discounted cash flow analysis as one of the methodologies to ascertain the fair value of our investments that do not have readily observable market prices. If applicable interest rates rise, then the assumed cost of capital for those portfolio companies would be expected to increase under the discounted cash flow analysis, and this effect would negatively impact their valuations if not offset by other factors. Conversely, a fall in interest rates can positively impact valuations of certain portfolio companies if not offset by other factors. These impacts could be substantial depending upon the magnitude of the change in interest rates. In certain cases, the valuations obtained from the discounted cash flow analysis and the other primary methodology we use, the market multiples approach, may yield different and offsetting results. For example, the positive impact of falling interest rates on discounted cash flow valuations may offset the negative impact of the market multiples valuation approach and may result in less of a decline in value than for those investments that had a readily observable market price. Finally, low interest rates related to monetary stimulus and economic stagnation may also negatively impact expected returns on all investments, as the demand for relatively higher return assets increases and supply decreases.

        Our Public Markets segment manages a number of funds and other accounts that invest capital in a variety of credit and equity strategies, including leveraged loans, high yield bonds and mezzanine debt. As a result, conditions in global credit and equity markets have a direct impact on both the performance of these investments as well as the ability to make additional investments on favorable terms in the future.

        In addition, our Capital Markets and Principal Activities segment generates fees through a variety of activities in connection with the issuance and placement of equity and debt securities and credit facilities, with the size of fees generally correlated to overall transaction sizes. As a result, the conditions in global equity and credit markets, as well as transaction activity in our Private Markets segment and to a significantly lesser extent, Public Markets segment, impact both the frequency and size of fees generated by this segment.

        Finally, conditions in commodity markets impact the performance of our portfolio companies in a variety of ways, including through the direct or indirect impact on the cost of the inputs used in their operations as well as the pricing and profitability of the products or services that they sell. The price of commodities has historically been subject to substantial volatility, which among other things, could be driven by economic, monetary, political or weather related factors. For example, in 2012, crude oil prices rose approximately 27% to a high of $99 per barrel on September 14, 2012, after falling to a low of $78 per barrel on June 28, 2012. Meanwhile, in 2012 the spot price of the GSCI Agriculture Index rose approximately 40% to a high of 533 on July 20, 2012 after falling to a low of 382 on June 15, 2012. If certain of our portfolio companies are unable to raise prices to offset increases in the cost of raw materials or other inputs, or if consumers defer purchases of or seek substitutes for the products of such portfolio companies, such portfolio companies could experience lower operating income which may in turn reduce the valuation of those portfolio companies. However, the results of operations and valuations of certain of our other portfolio companies, for example those involved in the development of oil and natural gas properties, may benefit from an increase or suffer from a decline in commodity prices. In particular, our Private Markets portfolio contains several natural resource-related investments whose values are influenced by natural gas prices. Consequently as natural gas prices have declined, the valuations of these natural resource-related investments in Private Markets have also declined. Furthermore, as we make additional investments in the oil and gas industry, the value of our portfolio may become increasingly sensitive to oil and gas prices.

Basis of Accounting

        The consolidated financial statements (referred to hereafter as the "financial statements") include the accounts of KKR's management and capital markets companies, the general partners of certain unconsolidated funds, general partners of consolidated funds and their respective consolidated funds and certain other entities.

        In accordance with accounting principles generally accepted in the United States of America, or GAAP, certain entities, including a substantial number of our funds, are consolidated notwithstanding the fact that we may hold only a minority economic interest or non-economic variable interest in those entities. In particular, the majority of our consolidated funds consist of funds in which we hold a general partner or managing member interest that gives us substantive controlling rights over such funds. With respect to our consolidated funds, we generally have operational discretion and control over the funds and investors in our funds do not hold any substantive rights that would enable them to impact the funds' ongoing governance and operating activities. As of December 31, 2012 our Private Markets segment included eleven consolidated investment funds and fourteen unconsolidated co-investment vehicles. Our Public Markets segment included eleven consolidated investment vehicles and 44 unconsolidated vehicles.

        When an entity is consolidated, we reflect the assets, liabilities, fees, expenses, investment income and cash flows of the consolidated entity on a gross basis. For example, the majority of the economic interests in a consolidated fund, which are held by third party investors in our funds, are reflected as noncontrolling interests. While the consolidation of a consolidated fund does not have an effect on the amounts of net income attributable to KKR or KKR's partners' capital that KKR reports, the consolidation does significantly impact the financial statement presentation. This is due to the fact that the assets, liabilities, fees, expenses and investment income of the consolidated funds are reflected on a gross basis while the allocable share of those amounts that are attributable to noncontrolling interests are reflected as single line items. The single line items in which the assets, liabilities, fees, expenses and investment income attributable to noncontrolling interests are recorded are presented as noncontrolling interests on the consolidated statements of financial condition and net income attributable to noncontrolling interests on the consolidated statements of operations. For a further discussion of our consolidation policies, see "—Critical Accounting Policies—Consolidation."

Key Financial Measures

Fees

        Fees consist primarily of (i) monitoring and consulting fees from providing advisory and other services, (ii) management and incentive fees from providing investment management services to unconsolidated funds, a specialty finance company, structured finance and other vehicles, and separately managed accounts and (iii) transaction fees earned in connection with successful investment transactions and from capital markets activities. These fees are based on the contractual terms of the governing agreements and are recognized when earned, which coincides with the period during which the related services are performed. Monitoring fees may provide for a termination payment following an initial public offering or change of control. These termination payments are recognized in the period when the related transaction closes.

        Fees reported in our consolidated financial statements do not include the management or incentive fees that we earn from consolidated funds, because those fees are eliminated in consolidation. However, because those management fees are earned from, and funded by, third-party investors in our funds who hold noncontrolling interests in the consolidated funds, net income attributable to KKR is increased by the amount of the management fees that are eliminated in consolidation. Accordingly, while the consolidation of funds impacts the amount of fees that are recognized in our financial statements, it does not affect the ultimate amount of net income attributable to KKR or KKR's partners' capital.

Expenses

Compensation and Benefits

        Compensation and benefits expense includes cash compensation consisting of salaries, bonuses, and benefits, as well as equity-based compensation consisting of charges associated with the vesting of equity-based awards and carry pool allocations.

        All KKR principals and other employees of certain consolidated entities receive a base salary that is paid by KKR or its consolidated entities, and is accounted for as Compensation and Benefits expense. These employees are also eligible to receive discretionary cash bonuses based on performance, overall profitability and other matters. While cash bonuses paid to most employees are borne by KKR and certain consolidated entities and result in customary compensation and benefits expense, cash bonuses that are paid to certain of KKR's principals are currently borne by KKR Holdings. These bonuses are funded with distributions that KKR Holdings receives on KKR Group Partnership Units held by KKR Holdings but are not then passed on to holders of unvested units of KKR Holdings. Because KKR principals are not entitled to receive distributions on units that are unvested, any amounts allocated to principals in excess of a principal's vested equity interests are reflected as employee compensation and benefits expense. These compensation charges are recorded based on the unvested portion of quarterly earnings distributions received by KKR Holdings at the time of the distribution.

        With respect to KKR's active and future funds and co-investment vehicles that provide for carried interest, KKR will allocate to its principals and other professionals a portion of the carried interest earned in relation to these funds as part of its carry pool. KKR currently allocates approximately 40% of the carry it earns from these funds and vehicles to its carry pool. For the purpose of the discussion under "—Consolidated Results of Operations," these amounts are accounted for as compensatory profit-sharing arrangements in conjunction with the related carried interest income and recorded as Compensation and Benefits expense for KKR employees and General, Administrative and Other expense for certain non-employee consultants and service providers in the consolidated statements of operations. However, for the purposes of the discussion under "—Segment Analysis" carry pool allocations are recorded as a component of Investment Income (Loss).

General, Administrative and Other

        General, administrative and other expense consists primarily of professional fees paid to legal advisors, accountants, advisors and consultants, insurance costs, travel and related expenses, communications and information services, depreciation and amortization charges and other general and operating expenses which are not borne by fund investors and are not offset by credits attributable to fund investors' noncontrolling interests in consolidated funds. General, administrative and other expense also consists of costs incurred in connection with pursuing potential investments that do not result in completed transactions, a substantial portion of which are borne by fund investors.

Investment Income (Loss)

Net Gains (Losses) from Investment Activities

        Net gains (losses) from investment activities consist of realized and unrealized gains and losses arising from our investment activities. The majority of our net gains (losses) from investment activities are related to our private equity investments. Fluctuations in net gains (losses) from investment activities between reporting periods is driven primarily by changes in the fair value of our investment portfolio as well as the realization of investments. The fair value of, as well as the ability to recognize gains from, our private equity investments is significantly impacted by the global financial markets, which, in turn, affects the net gains (losses) from investment activities recognized in any given period.

96

Table of Contents

Upon the disposition of an investment, previously recognized unrealized gains and losses are reversed and an offsetting realized gain or loss is recognized in the current period. Since our investments are carried at fair value, fluctuations between periods could be significant due to changes to the inputs to our valuation process over time. For a further discussion of our fair value measurements and fair value of investments, see "—Critical Accounting Policies—Fair Value Measurements."

Dividend Income

        Dividend income consists primarily of distributions that private equity funds receive from portfolio companies in which they invest. Private equity funds recognize dividend income primarily in connection with (i) dispositions of operations by portfolio companies, (ii) distributions of excess cash generated from operations from portfolio companies and (iii) other significant refinancing's undertaken by portfolio companies.

Interest Income

        Interest income consists primarily of interest that is received on our cash balances, principal assets and fixed income instruments in which our consolidated funds invest.

Interest Expense

        Interest expense is incurred from credit facilities entered into by KKR, debt issued by KKR, and debt outstanding at our consolidated funds entered into with the objective of enhancing returns or managing cash flow, which are generally not direct obligations of the general partners of our consolidated funds or management companies. In addition to these interest costs, we capitalize debt financing costs incurred in connection with new debt arrangements. Such costs are amortized into interest expense using either the interest method or the straight-line method, as appropriate. See "—Liquidity".

Income Taxes

        The KKR Group Partnerships and certain of their subsidiaries operate in the United States as partnerships for U.S. federal income tax purposes and as corporate entities in non-U.S. jurisdictions. Accordingly, these entities, in some cases, are subject to New York City unincorporated business taxes, or non-U.S. income taxes. Furthermore, we hold our interest in one of the KKR Group Partnerships through KKR Management Holdings Corp., which is treated as a corporation for U.S. federal income tax purposes, and certain other wholly-owned subsidiaries of the KKR Group Partnerships are treated as corporations for U.S. federal income tax purposes. Accordingly, such wholly-owned subsidiaries of KKR, including KKR Management Holdings Corp., and of the KKR Group Partnerships, are subject to federal, state and local corporate income taxes at the entity level and the related tax provision attributable to KKR's share of this income is reflected in the financial statements. We generate interest income to our unitholders and interest deductions to KKR Management Holdings Corp. as a result of a 2011 recapitalization of KKR Management Holdings Corp.

        We use the asset and liability method to account for income taxes in accordance with GAAP. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax basis using currently enacted tax rates. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period when the change is enacted. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that all or a portion of the deferred tax assets will not be realized.

        Tax laws are complex and subject to different interpretations by the taxpayer and respective governmental taxing authorities. Significant judgment is required in determining tax expense and in evaluating tax positions including evaluating uncertainties. We review our tax positions quarterly and adjust our tax balances as new information becomes available.

Net Income (Loss) Attributable to Noncontrolling Interests

        Net income (loss) attributable to noncontrolling interests represents the ownership interests that third parties hold in entities that are consolidated in the financial statements as well as the ownership interests in our KKR Group Partnerships that are held by KKR Holdings. The allocable share of income and expense attributable to these interests is accounted for as net income (loss) attributable to noncontrolling interests. Historically, the amount of net income (loss) attributable to noncontrolling interests has been substantial and has resulted in significant charges and credits in the statements of operations. Given the consolidation of certain of our investment funds and the significant ownership interests in our KKR Group Partnerships held by KKR Holdings, we expect this activity to continue.

Segment Operating and Performance Measures

        The segment key performance measures that follow are used by management in making operating and resource deployment decisions as well as assessing the overall performance of each of KKR's reportable business segments. The reportable segments for KKR's business are presented prior to giving effect to the allocation of income (loss) between KKR & Co. L.P. and KKR Holdings L.P. and as such represent the business in total. In addition, KKR's reportable segments are presented without giving effect to the consolidation of the funds that KKR manages.

        KKR discloses the following financial measures in this report that are calculated and presented using methodologies other than in accordance with GAAP. We believe that providing these performance measures on a supplemental basis to our GAAP results is helpful to unitholders in assessing the overall performance of KKR's businesses. These financial measures should not be considered as a substitute for similar financial measures calculated in accordance with GAAP. We caution readers that these non-GAAP financial measures may differ from the calculations of other investment managers, and as a result, may not be comparable to similar measures presented by other investment managers. Reconciliations of these non-GAAP financial measures to the most directly comparable financial measures calculated and presented in accordance with GAAP, where applicable, are included within "Financial Statements and Supplementary Data—Note 12. Segment Reporting."

Fee Related Earnings ("FRE")

        Fee related earnings is comprised of segment operating revenues less segment operating expenses and is used by management as an alternative measurement of the operating earnings of KKR and its business segments before investment income. We believe this measure is useful to unitholders as it provides additional insight into the operating profitability of our fee generating management companies and capital markets businesses. The components of FRE on a segment basis differ from the equivalent GAAP amounts on a consolidated basis as a result of: (i) the inclusion of management fees earned from consolidated funds that were eliminated in consolidation; (ii) the exclusion of fees and expenses of certain consolidated entities; (iii) the exclusion of charges relating to the amortization of intangible assets; (iv) the exclusion of charges relating to carry pool allocations; (v) the exclusion of non-cash equity charges and other non-cash compensation charges borne by KKR Holdings or incurred under the KKR & Co. L.P. 2010 Equity Incentive Plan; (vi) the exclusion of certain reimbursable expenses; and (vii) the exclusion of certain non-recurring items.

Economic Net Income (Loss) ("ENI")

        Economic net income (loss) is a measure of profitability for KKR's reportable segments and is used by management as an alternative measurement of the operating and investment earnings of KKR and its business segments. We believe this measure is useful to unitholders as it provides additional insight into the overall profitability of KKR's businesses inclusive of investment income and carried interest. ENI is comprised of: (i) FRE; plus (ii) segment investment income (loss), which is reduced for carry pool allocations and management fee refunds; less (iii) certain economic interests in KKR's segments held by third parties. ENI differs from net income (loss) on a GAAP basis as a result of:

98

Table of Contents

(i) the exclusion of the items referred to in FRE above; (ii) the exclusion of investment income (loss) relating to noncontrolling interests; and (iii) the exclusion of income taxes.

Assets Under Management ("AUM")

        Assets under management represent the assets from which KKR is entitled to receive fees or a carried interest and general partner capital. We believe this measure is useful to unitholders as it provides additional insight into KKR's capital raising activities and the overall activity in its investment funds and vehicles. KKR calculates the amount of AUM as of any date as the sum of: (i) the fair value of the investments of KKR's investment funds plus uncalled capital commitments from these funds; (ii) the fair value of investments in KKR's co-investment vehicles; (iii) the net asset value of certain of KKR's fixed income products; (iv) the value of outstanding structured finance vehicles; and (v) the fair value of other assets managed by KKR. KKR's definition of AUM is not based on any definition of AUM that may be set forth in the agreements governing the investment funds, vehicles or accounts that it manages or calculated pursuant to any regulatory definitions.

Fee Paying AUM ("FPAUM")

        Fee paying AUM represents only those assets under management from which KKR receives fees. We believe this measure is useful to unitholders as it provides additional insight into the capital base upon which KKR earns management fees. This relates to KKR's capital raising activities and the overall activity in its investment funds and vehicles, for only those funds and vehicles where KKR receives fees (i.e., excluding vehicles that receive only carried interest or general partner capital). FPAUM is the sum of all of the individual fee bases that are used to calculate KKR's fees and differs from AUM in the following respects: (i) assets from which KKR does not receive a fee are excluded (i.e., assets with respect to which it receives only carried interest) and (ii) certain assets, primarily in its private equity funds, are reflected based on capital commitments and invested capital as opposed to fair value because fees are not impacted by changes in the fair value of underlying investments.

Committed Dollars Invested

        Committed dollars invested is the aggregate amount of capital commitments that have been invested by KKR's investment funds and carry-yielding co-investment vehicles and is used as a measure of investment activity for KKR and its business segments during a given period. We believe this measure is useful to unitholders as it provides additional insight into KKR's investment of committed capital. Such amounts include: (i) capital invested by fund investors and fund co-investors with respect to which KKR is entitled to a fee or carried interest and (ii) capital invested by KKR's investment funds and vehicles.

Syndicated Capital

        Syndicated capital is the aggregate amount of debt or equity capital in transactions originated by KKR investment funds and vehicles, which has been distributed to third parties in exchange for a fee. It does not include capital committed to such transactions by carry-yielding co-investment vehicles, which is instead reported in committed dollars invested. Syndicated capital is used as a measure of investment activity for KKR and its business segments during a given period, and we believe that this measure is useful to unitholders as it provides additional insight into levels of syndication activity in KKR's Capital Markets and Principal Activities segment and across its investment platform.

Uncalled Commitments

        Uncalled commitments are used as a measure of unfunded capital commitments that KKR's investment funds and carry-paying co-investment vehicles have received from partners to contribute capital to fund future investments. We believe this measure is useful to unitholders as it provides additional insight into the amount of capital that is available to KKR's investment funds and vehicles to make future investments.

Adjusted Units

        Adjusted units are used as a measure of the total equity ownership of KKR that is held by KKR & Co. L.P. and KKR Holdings and represent the fully diluted unit count using the if-converted method. We believe this measure is useful to unitholders as it provides an indication of the total equity ownership of KKR as if all outstanding KKR Holdings units had been exchanged for common units of KKR & Co. L.P.

Total Distributable Earnings

        Total distributable earnings is the sum of (i) FRE, (ii) carry distributions received from KKR's investment funds which have not been allocated as part of its carry pool and (iii) net realized principal investment income; less (i) applicable local income taxes, if any, and (ii) noncontrolling interests. Net realized principal investment income includes, with respect to KKR's principal investments (i) realized investment gains and losses, (ii) dividend income and (iii) interest income, net of interest expense, earned from KKR's principal investments. KKR does not intend to distribute net realized principal investment income other than certain additional distributions that KKR may determine to make, which are intended to cover certain tax liabilities, as calculated by KKR. See "Liquidity—Liquidity Needs—Distribution Policy." We believe this measure is useful to unitholders as it provides a supplemental measure to assess performance, excluding the impact of mark-to-market gains (losses), and amounts available for distribution to KKR unitholders, however, total distributable earnings is not a measure that calculates actual distributions under KKR's current distribution policy.

Book Value

        Book value is a measure of the net assets of KKR's reportable segments and is used by management primarily in assessing the unrealized value of our investment portfolio, including carried interest, as well as our overall liquidity position. We believe this measure is useful to unitholders as it provides additional insight into the assets and liabilities of KKR excluding the assets and liabilities that are allocated to noncontrolling interest holders. Book value differs from the equivalent GAAP amounts on a consolidated basis primarily as a result of the exclusion of ownership interests attributable to KKR Holdings L.P.

Cash and Short-Term Investments

        Cash and short-term investments represent cash and liquid short-term investments in high-grade, short-duration cash management strategies used by KKR to generate additional yield on our excess liquidity and is used by management in evaluating KKR's liquidity position. We believe this measure is useful to unitholders as it provides additional insight into KKR's available liquidity. Cash and short-term investments differ from cash and cash equivalents on a GAAP basis as a result of the inclusion of liquid short-term investments in cash and short-term investments. The impact that these liquid short-term investments have on cash and cash equivalents on a GAAP basis is reflected in the consolidated statements of cash flows within cash flows from operating activities. Accordingly, the exclusion of these investments from cash and cash equivalents on a GAAP basis has no impact on cash provided (used) by operating activities, investing activities or financing activities. As of December 31, 2012, we had cash and short-term investments on a segment basis of $1,534.3 million. Excluding $303.8 million of liquid short-term investments, cash and short-term investments may be reconciled to cash and cash equivalents of $1,230.5 million as of December 31, 2012.

Consolidated Results of Operations

        The following is a discussion of our consolidated results of operations for the years ended December 31, 2012, 2011 and 2010. You should read this discussion in conjunction with the consolidated financial statements and related notes included elsewhere in this report. For a more detailed discussion of the factors that affected the results of operations of our three business segments in these periods, see "—Segment Analysis."

Table of Contents

        The following tables set forth information regarding our results of operations for the years ended December 31, 2012, 2011 and 2010.

Year ended December 31, 2012 compared to year ended December 31, 2011

Fees

        Fees were $568.4 million for the year ended December 31, 2012, a decrease of $155.2 million, compared to fees of $723.6 million for the year ended December 31, 2011. The net decrease was primarily due to a decrease in transaction fees of $106.1 million and a decrease in monitoring fees of $73.3 million, which were partially offset by a $17.9 million increase in management fees. The decrease in transaction fees was primarily due to a decrease in the number and size of investments completed in our Private Markets segment and to a lesser extent a decrease in overall capital markets transaction activity. In our Private Markets segment, during 2012 there were 17 transaction fee-generating investments with a total combined transaction value of approximately $6.5 billion as compared to 19 transaction fee-generating investments with a total combined transaction value of approximately $24.9 billion during 2011. Transaction fees vary by investment based upon a number of factors, the most significant of which are transaction size, the particular negotiations as to the amount of the fees, the complexity of the transaction and KKR's role in the transaction. In our capital markets business, the transaction fees we receive will depend on the amount of capital our funds and other vehicles deploy, the amount of capital this business syndicates and the number of transactions it completes for third party clients. The decrease in monitoring fees was primarily the result of $76.6 million of fees received in 2011 from the termination of monitoring fee arrangements in connection with the IPOs of HCA, Inc. and The Nielsen Company B.V., and the sale of Seven Media Group (media sector), while no such termination payments were received in 2012. These types of termination payments may occur in the future; however, they are infrequent in nature and are generally correlated with IPO or other

sale activity in our private equity portfolio. Also contributing to the decrease in monitoring fees was a decrease in expense reimbursements in connection with monitoring of portfolio companies of $16.2 million. The decrease in monitoring fees from termination payments and expense reimbursements was partially offset by an increase in recurring monitoring fees of $31.0 million. The increase in recurring monitoring fees was primarily the result of an increase in the number of portfolio companies paying a monitoring fee and an increase in the average size of the fee. During the year ended December 31, 2012, we had 40 portfolio companies that were paying an average monitoring fee of $2.9 million compared with 36 portfolio companies that were paying an average monitoring fee of $2.3 million during the year ended December 31, 2011. The increase in management fees was primarily due to an increase relating to the acquisition of Prisma as well as increases relating to new capital raised primarily in our Public Markets segment. As of December 31, 2012, our AUM and Fee Paying AUM excluded $4.0 billion relating to KKR Asian Fund II, $1.1 billion of unallocated commitments from a strategic partnership with a state pension plan, and $2.9 billion in connection with other Private Markets and Public Markets funds and co-investment vehicles for which we are currently not earning management fees. We will earn management fees on such AUM as this capital is deployed.

Expenses

        Expenses were $1.6 billion for the year ended December 31, 2012, an increase of $0.4 billion, compared to $1.2 billion for the year ended December 31, 2011. The increase was primarily attributable to a net increase in compensation and benefits of $0.4 billion due to (i) higher carried interest being allocated to the carry pool for employees during 2012 as compared to the prior period as a result of a higher level of investment income and (ii) higher equity-based compensation relating to equity grants under the KKR & Co. L.P. 2010 Equity Incentive Plan, partially offset by (iii) lower equity-based compensation reflecting fewer KKR Holdings units vesting for expense recognition purposes under the graded attribution method of expense recognition.

Net Gains (Losses) from Investment Activities

        Net gains from investment activities were $7.9 billion for the year ended December 31, 2012, an increase of $6.9 billion, compared to $1.0 billion for the year ended December 31, 2011. The increase was primarily driven by a higher level of net appreciation in our private equity portfolio in the current period when compared to the prior period. The following is a summary of net gains (losses) from investment activities:

        The majority of our net gains (losses) from investment activities relate to our private equity portfolio.

Analysis—Private Markets Segment" for further information regarding gains and losses in our private equity portfolio:

        The most significant driver of net gains (losses) from investment activities in our private equity investments for the year ended December 31, 2012 is related to unrealized gains and losses from changes in fair value. The net unrealized investment gains in our private equity portfolio were driven primarily by net unrealized gains of $3.4 billion, $1.9 billion and $0.9 billion in our 2006 Fund, European Fund II and Asian Fund, respectively. Approximately 24% of the net change in value for the year ended December 31, 2012 was attributable to changes in share prices of various publicly-listed investments, most notably increases in HCA, Inc., Dollar General Corporation (NYSE: DG) and NXP Semiconductors N.V., which were partially offset by decreases in Seven West Media Ltd. (AX: SWM), Far Eastern Horizon Ltd. (HK: 3360) and Tianrui Cement Co., Ltd. (HK: 1252). Our private portfolio contributed the remainder of the change in value, with the largest contributors being unrealized gains relating to Alliance Boots GmbH (healthcare sector), Oriental Brewery (consumer sector) and KION Group GmbH (manufacturing sector), which were partially offset by unrealized losses on Samson Resources (energy sector), China International Capital Corporation (financial services sector) and Toys R Us, Inc. (retail sector). The increased valuations are generally related to an increase in the value of market comparables and individual company performance, and in the case of Alliance Boots GmbH, an increase that primarily reflected the valuation of an agreement to sell a portion of the investment executed in June 2012. The decreased valuations are generally related to an unfavorable business outlook for the respective companies.

        The most significant driver of net gains (losses) from investment activities in our private equity investments for the year ended December 31, 2011 is related to unrealized gains and losses from changes in fair value. The net unrealized investment gains in our private equity portfolio was driven primarily by net unrealized gains of $0.9 billion and $0.4 billion in our 2006 Fund and Asian Fund, respectively. Approximately 78% of the net change in value for the year ended December 31, 2011 was attributable to changes in share prices of various publicly-listed investments, most notably increases in Dollar General Corporation, The Nielsen Company B.V. and Jazz Pharmaceuticals, Inc. (NASDAQ: JAZZ), partially offset by decreases in Legrand Holdings S.A. (ENXTPA: LR), Sealy Corporation (NYSE: ZZ) and Ma Anshan Modern Farming Co. (HK: 1117). Our private portfolio contributed the remainder of the change in value, with the largest contributor being unrealized gains relating to Oriental Brewery and U.N RO-RO Isletmeleri A.S. (transportation sector). These unrealized gains

were partially offset by unrealized losses relating to Biomet, Inc. (healthcare sector) and Energy Future Holdings Corp. (energy sector). The increased valuations, in the aggregate, generally related to individual company performance, while the decreased valuations, in the aggregate, generally related to declines in market comparables due to overall declines in equity markets or, in certain cases, an unfavorable business outlook.

Dividend Income

        Dividend income was $940.9 million for the year ended December 31, 2012, an increase of $715.8 million, compared to dividend income of $225.1 million for the year ended December 31, 2011. During the year ended December 31, 2012, we received $520.0 million of dividends from HCA, Inc., $188.1 million from Academy Sports and Outdoors (retail sector), $95.0 million from SunGard (technology sector), $78.5 million from TDC A/S (OMX: TDC), and an aggregate of $59.3 million of dividends from other investments. During the year ended December 31, 2011, we received $82.4 million of dividends from Dollar General Corporation, $68.3 million from Tarkett S.A. (manufacturing sector), $29.4 million from TDC A/S, $26.2 million from Legrand Holdings S.A. and an aggregate of $18.8 million of dividends from other investments. These types of dividends from portfolio companies are generally not recurring quarterly dividends and may occur in the future; however, their size and frequency are variable.

Interest Income

        Interest income was $358.6 million for the year ended December 31, 2012, an increase of $36.7 million, compared to $321.9 million for the year ended December 31, 2011. The increase primarily reflects a net increase in the level of fixed income instruments in our Public Markets investment vehicles.

Interest Expense

        Interest expense was $69.2 million for the year ended December 31, 2012, a decrease of $3.6 million, compared to $72.8 million for the year ended December 31, 2011. The decrease was primarily due to a net decrease in financing arrangements that were entered into by our consolidated funds with the objective of enhancing returns.

Income (Loss) Before Taxes

        Due to the factors described above, principally increased gains from investment activities, income before taxes was $8.1 billion for the year ended December 31, 2012, an increase of $7.1 billion, compared to $1.0 billion for the year ended December 31, 2011.

Net Income (Loss) Attributable to Redeemable Noncontrolling Interests

        Net income attributable to redeemable noncontrolling interests was $35.0 million for the year ended December 31, 2012, an increase of $30.7 million, compared to $4.3 million for the year ended December 31, 2011. The increase is due primarily to increases in the investment values of vehicles that allow for redemptions by limited partners, and to a lesser extent an increase in capital contributions as compared to the year ended December 31, 2011.

Net Income (Loss) Attributable to Noncontrolling Interests

        Net income attributable to noncontrolling interests was $7.4 billion for the year ended December 31, 2012, an increase of $6.5 billion, compared to $0.9 billion for the year ended December 31, 2011. The increase was primarily driven by the overall changes in the components of net gains (losses) from investment activities described above.

Year ended December 31, 2011 compared to year ended December 31, 2010

Fees

        Fees were $723.6 million for the year ended December 31, 2011, an increase of $288.2 million, compared to fees of $435.4 million for the year ended December 31, 2010. The net increase was primarily due to (i) an increase in gross monitoring fees of $76.8 million, (ii) an increase in gross transaction fees of $65.5 million, (iii) an increase in capital markets fees of $65.2 million and (iv) an increase in consulting fees of $56.1 million earned by an entity that was not consolidated prior to 2011. The increase in gross monitoring fees was primarily the result of $76.6 million in fees received during the year ended December 31, 2011 relating to the termination of monitoring agreements in connection with the IPOs of two portfolio companies, HCA, Inc. (NYSE: HCA) and The Nielsen Company (NYSE: NLSN), and the sale of Seven Media Group (ASX: SWM). Termination payments may occur in the future; however, they are infrequent in nature and are generally correlated with IPO or other sale activity in our private equity portfolio. Excluding the impact of termination payments and consulting fees, during the year ended December 31, 2011, we had 36 portfolio companies that were paying an average monitoring fee of $2.3 million compared with 33 portfolio companies that were paying an average monitoring fee of $2.6 million during the year ended December 31, 2010. The increase in transaction fees was primarily driven by an increase of $70.6 million in gross transaction fees received from transaction fee-generating investments, reflecting an increase in both the number and size of transaction fee-generating investments during the period. During 2011 there were 19 transaction fee-generating investments with a total combined transaction value of approximately $24.9 billion as compared to 13 transaction fee-generating investments with a total combined transaction value of approximately $9.9 billion during 2010. Transaction fees vary by investment based upon a number of factors, the most significant of which are transaction size, the particular negotiations as to the amount of the fees, the complexity of the transaction and KKR's role in the transaction. The increase in capital markets fees is primarily due to an increase in fees relating to underwriting, syndication, and other capital markets services driven by an increase in the number of capital markets transactions during 2011.

Expenses

        Expenses were $1.2 billion for the year ended December 31, 2011, a decrease of $0.6 billion, compared to $1.8 billion for the year ended December 31, 2010. The decrease was primarily due to the net effect of (i) a net decrease in equity-based payments of $690.0 million offset partially by (ii) an increase in cash-based compensation and benefits of $84.0 million. The net decrease in equity-based payments is due primarily to fewer KKR Holdings units vesting for expense recognition purposes under the graded attribution method of expense recognition, as well as a lower carry pool allocation as a result of the recognition of lower carried interest during 2011 as compared to the comparable prior period. The increase in cash-based compensation and benefits reflects the hiring of additional personnel and the inclusion of compensation incurred by an entity that was not consolidated prior to 2011. The remaining increases were due primarily to increases in occupancy and other operating expenses driven by the continued expansion of KKR's businesses during 2011.

Net Gains (Losses) from Investment Activities

        Net gains from investment activities were $1.0 billion for the year ended December 31, 2011, a decrease of $6.8 billion, compared to a net gain of $7.8 billion for the year ended December 31, 2010,

changes in fair value. The net unrealized investment gains in our private equity portfolio was driven primarily by net unrealized gains of $3.2 billion, $1.4 billion, $1.3 billion, $0.9 billion and $0.8 billion in our 2006 Fund, Millennium Fund, European Fund II, Asian Fund and European Fund, respectively. Approximately 40% of the net change in value for the year ended December 31, 2010 was attributable to changes in share prices of various publicly listed investments, notably increases in Dollar General Corporation, Legrand Holdings S.A. and NXP Semiconductors NV (NASDAQ: NXPI), which was taken public during the third quarter of 2010. Our private portfolio contributed the remainder of the change in value, with the largest contributor being unrealized gains relating to HCA Inc. (healthcare sector). These unrealized gains were partially offset by significant unrealized losses related to Energy Future Holdings Corp. (energy sector) and U.N Ro-Ro Isletmeleri A.S. (transportation sector). The increased valuations, in the aggregate, generally related to both improvements in market comparables and individual company performance. The increased valuations, in the aggregate, generally related to individual company performance, while the decreased valuations, in the aggregate, generally related to declines in market comparables due to overall declines in equity markets or, in certain cases, an unfavorable business outlook.

Dividend Income

        Dividend income was $225.1 million for the year ended December 31, 2011, a decrease of $1.1 billion, compared to dividend income of $1.3 billion for the year ended December 31, 2010. During the year ended December 31, 2011, we received $82.4 million of dividends from Dollar General Corporation (NYSE: DG), $68.3 million from Tarkett S.A. (manufacturing sector), $29.4 million from TDC A/S (OMX: TDC), $26.2 million from Legrand Holdings S.A. (ENXTPA: LR) and an aggregate of $18.8 million of dividends from other investments. During the year ended December 31, 2010, we received $931.1 million of dividends from HCA, Inc., $273.8 million from Visant Inc. (media sector), $34.4 million from Legrand Holdings S.A. and an aggregate of $11.0 million of dividends from other investments. These types of dividends from portfolio companies may occur in the future; however, their size and frequency are variable.

Interest Income

        Interest income was $321.9 million for the year ended December 31, 2011, an increase of $95.1 million, compared to $226.8 million for the year ended December 31, 2010. The increase primarily reflects the increase in the level of fixed income instruments in our public markets investment vehicles.

Interest Expense

        Interest expense was $72.8 million for the year ended December 31, 2011, an increase of $19.7 million, compared to $53.1 million for the year ended December 31, 2010. The increase was primarily due to higher average borrowing costs for the year ended December 31, 2011 driven by the issuance of the 2020 Senior Notes, as defined later in this report, in late September 2010.

Income (Loss) Before Taxes

        Due to the factors described above, principally decreased gains from investment activities, income before taxes was $1.0 billion for the year ended December 31, 2011, a decrease of $6.9 billion, compared to income before taxes of $7.9 billion for the year ended December 31, 2010.

Year ended December 31, 2012 compared to year ended December 31, 2011

Fees

        Fees were $539.6 million for the year ended December 31, 2012, a decrease of $76.3 million, compared to fees of $615.9 million for the year ended December 31, 2011. The decrease was primarily due to a decrease in gross transaction fees of $70.2 million and a decrease in gross monitoring fees of $47.2 million, partially offset by a decrease in fee credits of $47.6 million. The decrease in gross transaction fees was primarily the result of a decrease in the number and size of fee-generating investments completed. In the year ended December 31, 2012, there were 17 transaction fee-generating investments with a total combined transaction value of approximately $6.5 billion compared to 19 transaction fee-generating investments with a combined transaction value of $24.9 billion during the year ended December 31, 2011. Transaction fees vary by investment based upon a number of factors, the most significant of which are transaction size, the particular negotiations as to the amount of the fees, the complexity of the transaction and KKR's role in the transaction. The decrease in monitoring fees was primarily the result of $76.6 million of fees received in 2011 from the termination of monitoring fee arrangements in connection with the IPOs of HCA, Inc. and The Nielsen Company B.V., and the sale of Seven Media Group, while no such termination payments were received in 2012. These types of termination payments may occur in the future; however, they are infrequent in nature and are generally correlated with IPO or other sale activity in our private equity portfolio. This decrease in monitoring fees from termination payments was partially offset by an increase in recurring monitoring fees of $31.0 million. The increase in recurring monitoring fees was primarily the result of an increase in the number of portfolio companies paying a monitoring fee and the average size of the fee. During the year ended December 31, 2012, we had 40 portfolio companies that were paying an average monitoring fee of $2.9 million compared with 36 portfolio companies that were paying an average monitoring fee of $2.3 million during the year ended December 31, 2011. As of December 31, 2012, our AUM and Fee Paying AUM excluded $4.0 billion relating to KKR Asian Fund II, $1.1 billion of unallocated commitments from a strategic partnership with a state pension plan, and $2.5 billion in connection with other infrastructure, natural resources and private equity funds and co-investment vehicles for which we are currently not earning management fees. We will earn management fees on such AUM as this capital is deployed.

Expenses

        Expenses were $388.6 million for the year ended December 31, 2012, a decrease of $0.7 million, compared to expenses of $389.3 million for the year ended December 31, 2011. The decrease was primarily the result of a decrease in other operating expenses related to a lower level of broken deal expenses, reflecting reduced transaction activity, partially offset by an increase in compensation and benefits in connection with increased headcount.

Fee Related Earnings

        Fee related earnings in our Private Markets segment were $151.0 million for the year ended December 31, 2012, a decrease of $75.6 million, compared to fee related earnings of $226.6 million for the year ended December 31, 2011. The decrease was primarily due to the decrease in fees as described above.

Investment Income (Loss)

        Investment income was $684.1 million for the year ended December 31, 2012, an increase of $545.4 million, compared to investment income of $138.7 million for the year ended December 31, 2011. The increase was driven primarily by a higher level of net carried interest in our private equity funds.

        Net realized gains (losses) for the year ended December 31, 2011 consist primarily of realized gains from the partial sales of Dollar General Corporation, Avago Technologies Limited (NASDAQ: AVGO), Legrand Holdings S.A. and Hilcorp Resources, LLC (energy sector). These gains were partially offset by the write-off of our investment in Capmark Financial Group, Inc. (financial services sector).

        The following table presents net unrealized gains (losses) on carried interest by investment vehicle for the years ended December 31, 2012 and 2011:

        For the year ended December 31, 2012, the net unrealized gains of $364.9 million included $1,115.7 million attributable to net increases in the value of various portfolio companies, partially offset by $750.8 million of reversals of previously recognized net unrealized gains in connection with the occurrence of realization events such as partial or full sales of investments.

        Of the $1,115.7 million of net increases in value, 24% was attributable to increased share prices of various publicly held investments, the most significant of which were gains on HCA, Inc., Dollar General Corporation and NXP Semiconductors NV. These increases were partially offset by decreased

share prices of other publicly held investments, the most significant of which were Seven West Media Ltd., Far Eastern Horizon Ltd., and Tianrui Cement Co., Ltd. Our private portfolio contributed the remainder of the change in value, the most significant of which were gains relating to Alliance Boots GmbH, Oriental Brewery and KION Group GmbH. The unrealized gains on our private portfolio were partially offset by unrealized losses relating to Samson Resources, China International Capital Corporation, and Toys R Us. The increased valuations are generally related to an increase in the value of market comparables and individual company performance, and in the case of Alliance Boots GmbH, an increase that primarily reflected the valuation of an agreement to sell a portion of the investment executed in June 2012. The decreased valuations are generally related to an unfavorable business outlook for the respective companies.

        The reversals of previously recognized net unrealized gains of $750.8 million resulted primarily from the partial sales of Dollar General Corporation and Alliance Boots GmbH, and the sale of Legrand Holdings S.A.

        For the year ended December 31, 2011, the net unrealized losses of $242.1 million included $419.4 million of reversals of previously recognized net unrealized gains and losses in the connection with the occurrence of realization events such as partial sales or write-offs which were partially offset by $177.3 million of net unrealized gains reflecting net increases in the value of various portfolio companies. The reversals of previously recognized net unrealized gains and losses resulted primarily from the partial sales of Avago Technologies Limited, Dollar General Corporation, Legrand Holdings S.A. and Hilcorp Resources, LLC, which were partially offset by the write-off of Capmark Financial Group, Inc. Of the $177.3 million of net increases in value, 80.3% was attributable to increased share prices of various publicly held investments, the most significant of which were gains on Dollar General Corporation, The Nielsen Company B.V., and Jazz Pharmaceuticals, Inc. (NYSE: JAZZ). These increases were partially offset by decreased share prices of various publicly held investments, the most significant of which were losses on HCA, Inc., Sealy Corporation (NYSE: ZZ) and Ma Anshan Modern Farming Co. (HK:1117). Our private portfolio contributed the remainder of the change in value, the most significant of which were gains relating to Oriental Brewery (consumer sector) and Intelligence Ltd. (service sector). The increased valuations, in the aggregate, generally related to individual company performance. The unrealized gains on our private portfolio were partially offset by unrealized losses on Biomet, Inc. and Energy Future Holdings Corp. (energy sector) reflecting decreased valuations, in the aggregate, generally related to declines in the value of market comparables due to overall declines in equity markets or, in certain cases, an unfavorable business outlook.

        Dividend and interest income for the year ended December 31, 2012 consists primarily of dividends earned from HCA, Inc. and Academy Sports and Outdoors. Dividend and interest income for the year ended December 31, 2011 consists primarily of dividends earned from Dollar General Corporation. Management fee refunds amounted to $143.7 million for the year ended December 31, 2012, an increase of $126.1 million from the year ended December 31, 2011. The increase in management fee refunds primarily reflects an increased level of accrued carried interest in European Fund III and European Fund II, which triggered the recognition of a higher level of management fee refunds.

Economic Net Income (Loss)

        Economic net income (loss) in our Private Markets segment was $831.7 million for the year ended December 31, 2012, an increase of $468.9 million, compared to an economic net income of $362.8 million for the year ended December 31, 2011. The increase in investment income described above was the primary contributor to the period over period increase in economic net income.

Assets Under Management

        The following table reflects the changes in our Private Markets AUM from December 31, 2011 to December 31, 2012:

        AUM for the Private Markets segment was $49.1 billion at December 31, 2012, an increase of $5.5 billion, compared to $43.6 billion at December 31, 2011. The increase was primarily attributable to appreciation in the market value of our private equity portfolio of $8.5 billion and new capital raised of $7.4 billion related principally to North America Fund XI. These increases were partially offset by distributions in our private equity portfolio of $9.0 billion, comprised of $6.1 billion of realized gains and $2.9 billion of return of original cost, as well as a reduction in the fee base of the 2006 Fund of $1.3 billion as a result of the 2006 Fund entering its post-investment period.

        The change in value in our private equity portfolio was driven primarily by net unrealized gains of $3.4 billion, $1.9 billion and $0.9 billion in our 2006 Fund, European Fund II and Asian Fund, respectively. Approximately 24% of the net change in value for the year ended December 31, 2012 was attributable to changes in share prices of various publicly-listed investments, most notably increases in HCA, Inc., Dollar General Corporation, and NXP Semiconductors NV, which were partially offset by decreases in Seven West Media Ltd, Far Eastern Horizon Ltd and Tianrui Cement Co., Ltd. Our private portfolio contributed the remainder of the change in value, with the largest contributors being unrealized gains relating to Alliance Boots GmbH, Oriental Brewery and KION Group GmbH, which were partially offset by unrealized losses on Samson Resources, China International Capital Corporation and Toys R Us, Inc. The increased valuations are generally related to an increase in the value of market comparables and individual company performance, and in the case of Alliance Boots GmbH, an increase that primarily reflected the valuation of an agreement to sell a portion of the investment executed in June 2012. The decreased valuations are generally related to an unfavorable business outlook for the respective companies.

        FPAUM in our Private Markets segment was $41.2 billion at December 31, 2012, an increase of $3.3 billion, compared to $37.9 billion at December 31, 2011. The increase was primarily due to new capital raised of $7.5 billion relating primarily to North America Fund XI commencing its investment period at which time it began recognizing management fees. The increases were partially offset by the reduction in the fee base of the 2006 Fund of $3.2 billion as a result of the fund entering its post-investment period during which it earns management fees based on invested capital rather than committed capital at a lower rate as well as distributions of $1.1 billion.

        As of December 31, 2012, our AUM and Fee Paying AUM excluded $4.0 billion relating to KKR Asian Fund II, $1.1 billion of unallocated commitments from a strategic partnership with a state pension plan, and $2.5 billion in connection with other infrastructure, natural resources and private equity funds and co-investment vehicles for which we are currently not earning management fees. We will earn management fees on such AUM as this capital is deployed.

Committed Dollars Invested

        Committed dollars invested were $3.0 billion for the year ended December 31, 2012, a decrease of $2.0 billion, compared to committed dollars invested of $5.0 billion for the year ended December 31, 2011. The decrease was due to a decrease in both the number and size of private equity investments closed during the year ended December 31, 2012 as compared to the year ended December 31, 2011.

Uncalled Commitments

        As of December 31, 2012, our Private Markets Segment had $14.3 billion of remaining uncalled capital commitments that could be called for investments in new transactions.

Year ended December 31, 2011 compared to year ended December 31, 2010

Fees

        Fees were $615.9 million for the year ended December 31, 2011, an increase of $89.3 million, compared to fees of $526.6 million for the year ended December 31, 2010. The net increase was primarily due to an increase in gross monitoring fees of $76.8 million, an increase in gross transaction fees of $70.7 million and an increase in management fees of $34.2 million, partially offset by an increase in fee credits of $92.4 million. The increase in gross transaction fees was primarily the result in the increase in both the size and number of fee-generating investments completed. During 2011 there were 19 transaction fee-generating investments with a total combined transaction value of approximately $24.9 billion compared to 13 transaction fee-generating investments with a total combined transaction value of approximately $9.9 billion during 2010. Transaction fees vary by investment based upon a number of factors, the most significant of which are transaction size, the particular negotiations as to the amount of the fees, the complexity of the transaction and KKR's role in the transaction. The increase in gross monitoring fees was primarily the result of $76.6 million of fees received in the year ended December 31, 2011 from the termination of monitoring fee arrangements in connection with the IPOs or sales of three portfolio companies, HCA, Inc., The Nielsen Company B.V. and Seven Media Group, which impacted fees by $39.7 million, net of associated fee credits. Termination payments may occur in the future; however, they are infrequent in nature and are generally correlated with IPO or other sale activity in our private equity portfolio. Excluding the impact of termination payments, during the year ended December 31, 2011, we had 36 portfolio companies that were paying an average monitoring fee of $2.3 million compared with 33 portfolio companies that were paying an average monitoring fee of $2.6 million during the year ended December 31, 2010. The increase in management fees was primarily due to our China Growth Fund paying a full year of fees during 2011 as compared to only one quarter in 2010 and to a lesser extent an increase in the number of fee paying investment vehicles.

Expenses

The increase was primarily the result of an increase of $26.1 million in compensation and benefits expense and an increase in occupancy and related charges of $9.3 million, each of which is a reflection of the hiring of additional personnel and the continued expansion of this business. The remaining increases were due primarily to increases in professional fees and costs incurred in connection with the formation of new investment vehicles.

Investment Income (Loss)

        Investment income (loss) was $138.7 million for the year ended December 31, 2011, a decrease of $464.4 million, compared to investment income (loss) of $603.1 million for the year ended December 31, 2010 driven primarily by a lower level of appreciation in our private equity funds. For the year ended December 31, 2011, investment income (loss) was comprised primarily of net carried interest of $139.3 million.

        The following table presents the components of net carried interest for the year ended December 31, 2011 and 2010:

        Net realized gains (losses) for the year ended December 31, 2011 consist primarily of realized gains from the partial sales of Dollar General Corporation, Avago Technologies Limited, Legrand Holdings S.A. and Hilcorp Resources, LLC (energy sector). These gains were partially offset by the write-off of our investment in Capmark Financial Group, Inc. (financial services sector).

        Net realized gains (losses) for the year ended December 31, 2010 consist primarily of the sales of East Resources Inc. (energy sector), and partial sales of Dollar General Corporation, Legrand Holdings S.A. and Avago Technologies Limited.

        The following table presents net unrealized gains (losses) of carried interest by fund for the years ended December 31, 2011 and 2010:

        For the year ended December 31, 2011, the net unrealized losses of $242.1 million included $419.4 million of reversals of previously recognized net unrealized gains and losses in the connection with the occurrence of realization events such as partial sales or write-offs which were partially offset by $177.3 million of net unrealized gains reflecting net increases in the value of various portfolio companies. The reversals of previously recognized net unrealized gains and losses resulted primarily from the partial sales of Avago Technologies Limited, Dollar General Corporation, Legrand Holdings S.A. and Hilcorp Resources, LLC, which were partially offset by the write-off of Capmark Financial Group, Inc. Of the $177.3 million of net increases in value, 80.3% was attributable to increased share prices of various publicly held investments, the most significant of which were gains on Dollar General Corporation, The Nielsen Company B.V., and Jazz Pharmaceuticals, Inc. (NYSE: JAZZ). These increases were partially offset by decreased share prices of various publicly held investments, the most significant of which were losses on HCA, Inc., Sealy Corporation (NYSE: ZZ) and Ma Anshan Modern Farming Co. (HK:1117). Our private portfolio contributed the remainder of the change in value, the most significant of which were gains relating to Oriental Brewery (consumer sector) and Intelligence Ltd. (service sector). The increased valuations, in the aggregate, generally related to individual company performance. The unrealized gains on our private portfolio were partially offset by unrealized losses on Biomet, Inc. (healthcare sector) and Energy Future Holdings Corp. (energy sector) reflecting decreased valuations, in the aggregate, generally related to declines in market comparables due to overall declines in equity markets or, in certain cases, an unfavorable business outlook.

        For the year ended December 31, 2010, approximately 33% of net unrealized gains from changes in value were attributable to increased share prices of various publicly held investments, the most significant of which were Dollar General Corporation and Legrand Holdings S.A. Our private portfolio contributed the remainder of the net unrealized gains from changes in value, the most significant of which were HCA Inc., Alliance Boots GmbH (healthcare sector) and US Foods, formerly known as US Foodservice (retail sector). The increased valuations, in the aggregate, generally related to both improvements in market comparables and individual company performance.

        Dividend and interest income for the year ended December 31, 2011 consists primarily of dividends earned from Dollar General Corporation. Dividend and interest income for the year ended December 31, 2010 consists primarily of dividends earned from HCA Inc. and Visant Inc. Management

fee refunds amounted to $17.6 million for the year ended December 31, 2011, a decrease of $125.9 million from the year ended December 31, 2010. The lower management fee refund figure primarily reflects the 2006 Fund becoming carry-earning in 2010, as well as a benefit in the current year due to certain funds declining in value which triggered the reversal of management fee refunds related to management fees earned in the prior year.

Economic Net Income

        Economic net income in our Private Markets segment was $362.8 million for the year ended December 31, 2011, a decrease of $421.8 million, compared to economic net income of $784.6 million for the year ended December 31, 2010. The decrease in investment income described above was the primary contributor to the period over period decrease in economic net income.

Assets Under Management

        The following table reflects the changes in our Private Markets AUM from December 31, 2010 to December 31, 2011:

        AUM for the Private Markets segment was $43.6 billion at December 31, 2011, a decrease of $2.6 billion, compared to $46.2 billion at December 31, 2010. The decrease was primarily attributable to distributions from our funds totaling $6.5 billion which was comprised of $4.3 billion of realized gains and $2.2 billion of return of original cost. This decrease was partially offset by $2.3 billion in new capital raised relating primarily to our natural resources strategy and our infrastructure strategy as well as net unrealized gains from changes in the market value of our private equity portfolio of $1.6 billion.

        The net unrealized investment gains in our private equity funds were driven primarily by net unrealized gains of $0.9 billion and $0.4 billion in our 2006 Fund and Asian Fund, respectively. Approximately 78% of the net change in value for the year ended December 31, 2011 was attributable to changes in share prices of various publicly-listed investments, most notably increases in Dollar General Corporation, The Nielsen Company B.V. and Jazz Pharmaceuticals, Inc., partially offset by decreases in Legrand Holdings S.A., Sealy Corporation and Ma Anshan Modern Farming Co. Our private portfolio contributed the remainder of the change in value, with the largest contributor being unrealized gains relating to Oriental Brewery and U.N RO-RO Isletmeleri A.S. (transportation sector). These unrealized gains were partially offset by unrealized losses relating to Biomet, Inc. and Energy Future Holdings Corp. The increased valuations, in the aggregate, generally related to individual company performance, while the decreased valuations, in the aggregate, generally related to declines in market comparables due to overall declines in equity markets or, in certain cases, an unfavorable business outlook.

The increase is primarily attributable to an increase in management fees of $20.2 million and incentive fees of $9.7 million. The increase in management fees is due primarily to the acquisition of Prisma and to a lesser extent new capital raised. The increase in incentive fees is due to incentive fees earned in our equity strategies business and hedge fund solutions platforms during 2012, neither of which businesses earned incentive fees in 2011, as well as an increase in incentive fees received from KFN resulting from a higher level of income when compared to the prior period. As of December 31, 2012, our AUM and Fee Paying AUM excluded approximately $0.4 billion relating to certain special situations and direct lending investment vehicles for which we are currently not earning management fees.

syndication transaction sizes were significantly higher for the year ended December 31, 2011 as compared to the year ended December 31, 2012.

These realized gains were partially offset by $102.7 million of realized losses primarily in connection with the sale of certain of our private equity interests. The net unrealized gains related primarily to increases in the value of various private equity investments, most notably Alliance Boots GmbH, HCA, Inc., KION Group GmbH, and Dollar General Corporation. These unrealized gains were partially offset by unrealized losses on Samson Resources, as well as reversals of previously recognized net unrealized gains in the connection with the occurrence of realization events.

These net unrealized gains were offset by the reversals of previously recognized unrealized gains in connection with partial sales of private equity investments, most notably HCA, Inc. and Dollar General Corporation.

        For the year ended December 31, 2010, net realized gains were comprised of $150.3 million of gains from the sale of certain private equity investments, the most significant of which was the partial sale of Dollar General Corporation, and $124.1 million of losses from the sale of non-private equity investments, which related primarily to the write-off of our investment in Aero Technical Support & Services S.a.r.L (industrial sector). The net unrealized gains were comprised of $821.8 million of net unrealized appreciation of private equity investments, the most significant of which were Dollar General Corporation and NXP Semiconductors NV. Dividend income of $226.6 million in 2010 primarily consisted of dividends earned from HCA Inc.

Economic Net Income (Loss)

        Economic net income in our Capital Markets and Principal Activities segment was $330.2 million for the year ended December 31, 2011, a decrease of $1.0 billion, compared to economic net income of $1.3 billion for the year ended December 31, 2010. The decrease in investment income described above was the primary contributor to the period over period decrease in economic net income.

Liquidity

        We manage our liquidity and capital requirements by focusing on our cash flows before the consolidation of our funds and the effect of normal changes in short term assets and liabilities, which we anticipate will be settled for cash within one year. Our primary cash flow activities on an unconsolidated basis typically involve: (i) generating cash flow from operations; (ii) generating income from investment activities, including the sale of investments and other principal assets; (iii) funding capital commitments that we have made to our funds, (iv) developing and funding new investment strategies, investment products and other growth initiatives, including acquisitions; (v) underwriting commitments within our capital markets business; (vi) distributing cash flow to our fund investors and unitholders; and (vii) borrowings, interest payments and repayments under credit agreements, our senior notes and other borrowing arrangements. As of December 31, 2012, we had cash and short-term investments on a segment basis of $1,534.3 million.

Sources of Liquidity

        Our primary sources of liquidity consist of amounts received from: (i) our operating activities, including the fees earned from our funds, managed accounts, portfolio companies, capital markets transactions and other investment products; (ii) realizations on carried interest from our investment funds; (iii) realizations on and sales of investments and other principal assets; and (iv) borrowings under our credit facilities, debt offerings and other borrowing arrangements. In addition, we may generate cash proceeds from sales of our common units described below.

        With respect to our private equity funds, carried interest is distributed to the general partner of a private equity fund with a clawback or net loss sharing provision only after all of the following are met: (i) a realization event has occurred (e.g., sale of a portfolio company, dividend, etc.); (ii) the vehicle has achieved positive overall investment returns since its inception, in excess of performance hurdles where applicable; and (iii) with respect to investments with a fair value below cost, cost has been returned to fund investors in an amount sufficient to reduce remaining cost to the investments' fair value. As of December 31, 2012, certain of our funds had met the first and second criteria, as described above, but did not meet the third criteria. In these cases, carried interest accrues on the consolidated statement of operations, but will not be distributed in cash to us as the general partner of an investment fund upon a realization event. For a fund that has a fair value above cost, overall, but has one or more investments where fair value is below cost, the shortfall between cost and fair value for such investments is referred to as a "netting hole." When netting holes are present, realized gains on individual investments that would otherwise allow the general partner to receive carried interest distributions are instead used to return invested capital to our funds' limited partners in an amount equal to the netting hole. Once netting holes have been filled with either (a) return of capital equal to the netting hole for those investments where fair value is below cost, or (b) increases in the fair value of those investments where fair value is below cost, then realized carried interest will be distributed to the general partner upon a realization event.

        As of December 31, 2012, netting holes existed at certain of our private equity funds, the most significant of which were our domestic 2006 Fund partnership and our European Fund II, which had netting holes of approximately $299 million and $516 million, respectively. These amounts do not reflect realization activity occurring subsequent to December 31, 2012. In accordance with the criteria set forth above, our netting holes may increase or decrease in the future.

        We have access to funding under various credit facilities and other borrowing arrangements that we have entered into with major financial institutions or which we receive from the capital markets. The following is a summary of the principal terms of these sources of funding.

Revolving Credit Agreements

        For the year ended December 31, 2012, there were no borrowings made, and as of December 31, 2012, no borrowings were outstanding under either of the revolving credit agreements described below, except for a letter of credit under the Corporate Credit Agreement described further below. We may, however, utilize these facilities prospectively in the normal course of our operations.

•

On February 26, 2008, Kohlberg Kravis Roberts & Co. L.P. entered into a credit agreement with a major financial institution (the "Corporate Credit Agreement"). The Corporate Credit Agreement originally provided for revolving borrowings of up to $1.0 billion, with a $50.0 million sublimit for swing-line notes and a $25.0 million sublimit for letters of credit. On February 22, 2011, the parties amended the terms of the Corporate Credit Agreement such that effective March 1, 2011, availability for borrowings under the credit facility was reduced from $1.0 billion to $700 million and the maturity was extended to March 1, 2016. In addition, the KKR Group Partnerships became co-borrowers of the facility, and KKR & Co. L.P. and the issuer of the 2020 Senior Notes (discussed below) became guarantors of the Corporate Credit Agreement, together with certain general partners of our private equity funds. On June 3, 2011, the Corporate Credit Agreement was amended to admit a new lender, subject to the same terms and conditions, to provide a commitment of $50 million. This commitment increased the availability for borrowings under the credit facility to $750 million. On June 22, 2012, KKR requested the issuance of a letter of credit in the amount of $14.5 million under the Corporate Credit Agreement. The beneficiary of this letter of credit is an unaffiliated third party. The letter of credit was issued on July 2, 2012 and initially set to expire on July 3, 2013. On August 20, 2012, the letter of credit in connection with this fee-generating transaction was increased to $20.0 million and the expiration date was extended to August 1, 2013. A $5.0 million sublimit for letters of credit remains available under the Corporate Credit Agreement.



•

On February 27, 2008, KKR Capital Markets entered into a credit agreement with a major financial institution (the "KCM Credit Agreement") for use in KKR's capital markets business. The KCM Credit Agreement, as amended, provides for revolving borrowings of up to $500 million with a $500 million sublimit for letters of credit. On March 30, 2012, an agreement was made to extend the maturity of the KCM Credit Agreement from February 27, 2013 to March 30, 2017. In addition to extending the terms, certain other terms of the KCM Credit Agreement were renegotiated including a reduction of the cost of funding on amounts drawn and a reduced commitment fee. Borrowings under this facility may only be used for our capital markets business.

Senior Notes

•

On September 29, 2010, KKR Group Finance Co. LLC, a subsidiary of KKR Management Holdings Corp., issued $500 million aggregate principal amount of 6.375% Senior Notes (the "2020 Senior Notes"), which were issued at a price of 99.584%. The 2020 Senior Notes are unsecured and unsubordinated obligations of the issuer and will mature on September 29, 2020, unless earlier redeemed or repurchased. The 2020 Senior Notes are fully and unconditionally guaranteed, jointly and severally, by KKR & Co. L.P. and the KKR Group Partnerships. The guarantees are unsecured and unsubordinated obligations of the guarantors. The 2020 Senior Notes bear interest at a rate of 6.375% per annum, accruing from September 29, 2010.

The indenture, as supplemented by a first supplemental indenture, relating to the 2020 Senior Notes includes covenants, including limitations on the issuer's and the guarantors' ability to, subject to exceptions, incur indebtedness secured by liens on voting stock or profit participating equity interests of their subsidiaries or merge, consolidate or sell, transfer or lease assets. The indenture, as supplemented, also provides for events of default and further provides that the

Table of Contents

trustee or the holders of not less than 25% in aggregate principal amount of the outstanding 2020 Senior Notes may declare the 2020 Senior Notes immediately due and payable upon the occurrence and during the continuance of any event of default after expiration of any applicable grace period. In the case of specified events of bankruptcy, insolvency, receivership or reorganization, the principal amount of the 2020 Senior Notes and any accrued and unpaid interest on the 2020 Senior Notes automatically becomes due and payable. All or a portion of the 2020 Senior Notes may be redeemed at the issuer's option in whole or in part, at any time, and from time to time, prior to their stated maturity, at the make-whole redemption price set forth in the 2020 Senior Notes. If a change of control repurchase event occurs, the 2020 Senior Notes are subject to repurchase by the issuer at a repurchase price in cash equal to 101% of the aggregate principal amount of the 2020 Senior Notes repurchased plus any accrued and unpaid interest on the 2020 Senior Notes repurchased to, but not including, the date of repurchase.

•

On February 1, 2013, KKR Group Finance Co. II LLC, a subsidiary of KKR Management Holdings Corp., issued $500 million aggregate principal amount of 5.50% Senior Notes (the "2043 Senior Notes"), which were issued at a price of 98.856%. The 2043 Senior Notes are unsecured and unsubordinated obligations of the issuer and will mature on February 1, 2043, unless earlier redeemed or repurchased. The 2043 Senior Notes are fully and unconditionally guaranteed, jointly and severally, by KKR & Co. L.P. and the KKR Group Partnerships. The guarantees are unsecured and unsubordinated obligations of the guarantors. The 2043 Senior Notes bear interest at a rate of 5.50% per annum, accruing from February 1, 2013. Interest is payable semi-annually in arrears on February 1 and August 1 of each year, commencing on August 1, 2013.

The indenture, as supplemented by a first supplemental indenture, relating to the 2043 Senior Notes includes covenants, including limitations on the issuer's and the guarantors' ability to, subject to exceptions, incur indebtedness secured by liens on voting stock or profit participating equity interests of their subsidiaries or merge, consolidate or sell, transfer or lease assets. The indenture, as supplemented, also provides for events of default and further provides that the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding 2043 Senior Notes may declare the 2043 Senior Notes immediately due and payable upon the occurrence and during the continuance of any event of default after expiration of any applicable grace period. In the case of specified events of bankruptcy, insolvency, receivership or reorganization, the principal amount of the 2043 Senior Notes and any accrued and unpaid interest on the 2043 Senior Notes automatically becomes due and payable. All or a portion of the 2043 Senior Notes may be redeemed at the issuer's option in whole or in part, at any time, and from time to time, prior to their stated maturity, at the make-whole redemption price set forth in the 2043 Senior Notes. If a change of control repurchase event occurs, the 2043 Senior Notes are subject to repurchase by the issuer at a repurchase price in cash equal to 101% of the aggregate principal amount of the 2043 Senior Notes repurchased plus any accrued and unpaid interest on the 2043 Senior Notes repurchased to, but not including, the date of repurchase.

Common Units

•

On March 27, 2012, KKR & Co. L.P. filed a registration statement with the Securities and Exchange Commission for the sale by us from time to time of up to 1,500,000 common units of KKR & Co. L.P. to generate cash proceeds up to (i) the amount of withholding taxes, social benefit payments or similar payments payable by us in respect of awards granted pursuant to the Equity Incentive Plan, and (ii) the amount of cash delivered in respect of awards granted pursuant to the Equity Incentive Plan that are settled in cash instead of common units. The administrator of the Equity Incentive Plan is expected to reduce the maximum number of common units eligible to be issued under the Equity Incentive Plan by the number of common

131

Table of Contents

units issued and sold pursuant to the registration statement unless such reduction is already provided for with respect to such awards under the terms of the Equity Incentive Plan. The Securities and Exchange Commission declared the registration statement effective on April 11, 2012. During the year ended December 31, 2012, 468,439 common units were issued and sold under the registration statement and are included in our basic common units outstanding as of December 31, 2012.

Liquidity Needs

        We expect that our primary liquidity needs will consist of cash required to: (i) continue to grow our business, including seeding new strategies and funding our capital commitments made to existing and future funds, co-investments and any net capital requirements of our capital markets companies; (ii) service debt obligations that may give rise to future cash payments; (iii) fund cash operating expenses; (iv) pay amounts that may become due under our tax receivable agreement with KKR Holdings as described below; (v) make cash distributions in accordance with our distribution policy; (vi) underwrite commitments within our capital markets business and (vii) acquire additional principal assets, including the acquisition of other investment advisory and capital markets businesses. We may also require cash to fund contingent obligations including those under clawback, net loss sharing arrangements, contingent purchase price payments in connection with our acquisitions of or investments in equity stakes in other businesses or obligations in connection with the defense, prosecution, or settlement of legal claims. See "—Liquidity—Contractual Obligations, Commitments and Contingencies on an Unconsolidated Basis." We believe that the sources of liquidity described above will be sufficient to fund our working capital requirements for at least the next 12 months.

Capital Commitments

        The agreements governing our active investment funds generally require the general partners of the funds to make minimum capital commitments to such funds, which usually range from 2% to 4% of a fund's total capital commitments at final closing. In addition, we are responsible for certain limited partner interests in some of our private equity funds. The following table presents our uncalled commitments to our active investment funds as of December 31, 2012:

132

---

Table of Contents

        As of December 31, 2012, KKR had unfunded commitments consisting of (i) $677.9 million to its active private equity and other investment vehicles, (ii) $125.0 million to KKR Asian Fund II L.P. for which the investment period has not yet commenced, subject to adjustment, (iii) $94.2 million in connection with commitments by KKR's capital markets business related to revolving credit facilities of Portfolio Companies and other companies and (iv) $150.0 million relating to our joint venture with Stone Point Capital and CPPIB as described below. Whether these amounts are actually funded, in whole or in part depends on the terms of such commitments, including the satisfaction or waiver of any conditions to funding.

        In addition to the commitments described above, KKR has earmarked approximately $440 million to fund, acquire and develop new strategies, products and initiatives including natural resources, real estate and other strategies. The amounts earmarked to fund and develop new strategies, products and initiatives may be revised or terminated by KKR in its discretion from time to time.

Acquisition of Prisma Capital Partners

        On October 1, 2012, KKR closed its previously announced acquisition of 100% of the equity interests of Prisma Capital Partners LP and its affiliates ("Prisma"). Prisma is a provider of customized hedge fund solutions with approximately $8.1 billion in assets under management as of December 31, 2012. The initial purchase price was paid by KKR at the closing in cash. KKR may also become obligated to make future purchase price payments in the years 2014 and 2017 based on whether the Prisma business grows to achieve certain operating performance metrics when measured in such years. KKR has the right in its sole discretion to pay a portion of such future purchase price payments, if any, in KKR & Co. L.P. common units rather than in cash.

Joint Venture with Stone Point Capital and CPPIB

        On January 17, 2013, KKR entered into a joint venture partnership with Stone Point Capital ("Stone Point") and CPPIB Credit Investments, Inc. ("CPPIB"), to establish MerchCap Solutions LLC ("MCS", formerly known as "KKR—SPC Merchant Advisors LLC"). MCS will seek to provide capital markets services to mid-market and sponsor-backed companies as well as make certain principal investments to support client needs. KKR and Stone Point each committed $150 million of equity and CPPIB committed an additional $50 million to MCS to support its business. KKR expects that certain capital markets activities for third parties (other than KKR and its Portfolio Companies) will be principally conducted by MCS.

Acquisition of Nephila

        On January 23, 2013, we acquired a 24.9% interest in Nephila Capital Ltd. ("Nephila"). Nephila is a leading investment manager that offers a broad range of investment products focusing on reinsurance risk, investing in instruments such as insurance-linked securities, catastrophe bonds, and weather derivatives. Nephila has assets under management of approximately $8 billion as of January 1, 2013.

Tax Receivable Agreement

        We and certain intermediate holding companies that are taxable corporations for U.S. federal, state and local income tax purposes, may be required to acquire KKR Group Partnership Units from time to time pursuant to our exchange agreement with KKR Holdings. KKR Management Holdings L.P. made an election under Section 754 of the Internal Revenue Code that will remain in effect for each taxable year in which an exchange of KKR Group Partnership Units for common units occurs, which may result in an increase in our intermediate holding companies' share of the tax basis of the assets of the KKR Group Partnerships at the time of an exchange of KKR Group Partnership Units. Certain of these exchanges are expected to result in an increase in our intermediate holding

133

---

Table of Contents

companies' share of the tax basis of the tangible and intangible assets of the KKR Group Partnerships, primarily attributable to a portion of the goodwill inherent in our business that would not otherwise have been available. This increase in tax basis may increase depreciation and amortization deductions for tax purposes and therefore reduce the amount of income tax our intermediate holding companies would otherwise be required to pay in the future. This increase in tax basis may also decrease gain (or increase loss) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets.

        We have entered into a tax receivable agreement with KKR Holdings, which requires our intermediate holding companies to pay to KKR Holdings, or to executives who have exchanged KKR Holdings units for KKR common units as transferees of KKR Group Partnership Units, 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax that the intermediate holding companies realize as a result of the increase in tax basis described above, as well as 85% of the amount of any such savings the intermediate holding companies realize as a result of increases in tax basis that arise due to future payments under the agreement. A termination of the agreement or a change of control could give rise to similar payments based on tax savings that we would be deemed to realize in connection with such events. In the event that other of our current or future subsidiaries become taxable as corporations and acquire KKR Group Partnership Units in the future, or if we become taxable as a corporation for U.S. federal income tax purposes, we expect that each will become subject to a tax receivable agreement with substantially similar terms.

        These payment obligations are obligations of our intermediate holding companies and not the KKR Group Partnerships. As such, cash payments received by common unitholders may vary from those received by current and former holders of KKR Group Partnership Units (held by KKR Holdings and our principals) to the extent payments are made to those parties under the tax receivable agreement. Payments made under the tax receivable agreement are required to be made within 90 days of the filing of the tax returns of our intermediate holding companies, which may result in a timing difference between the tax savings received by KKR's intermediate holdings companies and the cash payments made to the selling holders of KKR Group Partnership Units.

        As of December 31, 2012, approximately $2.9 million of cumulative cash payments have been made under the tax receivable agreement. We expect our intermediate holding companies to benefit from the remaining 15% of cash savings, if any, in income tax that they realize. As of December 31, 2012, $0.5 million of cumulative income tax savings have been realized.

Distributions

        KKR intends to make quarterly cash distributions in amounts that in the aggregate are expected to constitute substantially all of the cash earnings of its investment management business each year in excess of amounts determined by KKR to be necessary or appropriate to provide for the conduct of its business, to make appropriate investments in its business and its investment funds and to comply with applicable law and any of its debt instruments or other agreements. KKR does not intend to distribute net realized principal investment income, other than certain additional distributions that KKR may determine to make. These additional distributions, if any, are intended to cover certain tax liabilities, as calculated by KKR. When KKR & Co. L.P. receives distributions from the KKR Group Partnerships (the holding companies of the KKR business), KKR Holdings receives its pro rata share of such distributions from the KKR Group Partnerships. For purposes of KKR's distribution policy, its distributions are expected to consist of (i) FRE, (ii) carry distributions received from KKR's investment funds which have not been allocated as part of its carry pool and (iii) any additional distributions for certain taxes as described above. This amount is expected to be reduced by (i) corporate and applicable local taxes, if any, (ii) noncontrolling interests and (iii) amounts determined by KKR to be necessary or appropriate for the conduct of its business and other matters as discussed above.

134

Table of Contents

        Total distributable earnings were $1,449.4 million for year ended December 31, 2012, up from $782.6 million and $738.2 million for the years ended December 31, 2011 and 2010, respectively. This increase was primarily related to the increase in net realized principal investment income and realized cash carry from the sale of private equity investments. See "Segment Analysis" for further discussion surrounding our private equity and principal realizations. Total distributable earnings is not a measure that calculates actual distributions under KKR's current distribution policy.

        The declaration and payment of any distributions are subject to the discretion of the board of directors of the general partner of KKR & Co. L.P. and the terms of its limited partnership agreement. There can be no assurance that distributions will be made as intended or at all or that such distributions will be sufficient to pay any particular KKR & Co. L.P. unitholder's actual U.S. or non-U.S. tax liability.

        The following table presents our distribution calculation for years ended December 31, 2012, 2011 and 2010 as described above:

Other Liquidity Needs

        We may also be required to fund various underwriting commitments in our capital markets business in connection with the underwriting of loans, securities or other financial instruments. We

135

Table of Contents

generally expect that these commitments will be syndicated to third parties or otherwise fulfilled or terminated, although we may in some instances elect to retain a portion of the commitments for our own account.

Contractual Obligations, Commitments and Contingencies on an Unconsolidated Basis

        In the ordinary course of business, we enter into contractual arrangements that may require future cash payments. The following table sets forth information relating to anticipated future cash payments as of December 31, 2012 on an unconsolidated basis.

        The commitment table above excludes contractual amounts owed under the tax receivable agreement, because the ultimate amount and timing of the amounts due are not presently known. As of December 31, 2012, a payable of $70.4 million has been recorded in due to affiliates in the consolidated financial statements representing management's best estimate of the amounts currently expected to be owed under the tax receivable agreement. As of December 31, 2012, approximately $2.9 million of cumulative cash payments have been made under the tax receivable agreement. See "—Liquidity Needs—Tax Receivable Agreement".

        The commitment table above excludes contingent consideration payments that may be owed in connection with the Prisma acquisition because the ultimate amounts due are not presently known. As of December 31, 2012, the fair value of the contingent consideration obligation was estimated to be $71.3 million. See Note 13 "Acquisitions" in our financial statements included elsewhere in this report.

136

---

Table of Contents

        In the normal course of business, we also enter into contractual arrangements that contain a variety of representations and warranties and that include general indemnification obligations. Our maximum exposure under such arrangements is unknown due to the fact that the exposure would relate to claims that may be made against us in the future. Accordingly, no amounts have been included in our consolidated financial statements as of December 31, 2012 relating to indemnification obligations.

        The partnership documents governing our private equity funds generally include a "clawback" provision that, if triggered, may give rise to a contingent obligation that may require the general partner to return amounts to the fund for distribution to investors in our funds at the end of the life of the fund. Our principals are responsible for any clawback obligation relating to carry distributions received prior to October 1, 2009 up to a maximum of $223.6 million. Carry distributions arising subsequent to October 1, 2009 may give rise to clawback obligations that will be allocated generally to carry pool participants and KKR. As of December 31, 2012, assuming that all applicable private equity funds were liquidated at no value, the amount of carried interest distributed that would be subject to this clawback provision would be $1,095.4 million, of which $871.8 million would be borne by KKR and carry pool participants and $223.6 million would be borne by our principals. Had the investments in such funds been liquidated at their December 31, 2012 fair values, there would have been no clawback obligation.

        We have other carry-paying vehicles, including our mezzanine, infrastructure and special situations funds, which generally include clawback provisions; however, no distributions of carried interest have been made with respect to these vehicles as of December 31, 2012.

        The instruments governing certain of our private equity funds that were contributed to us may also include a "net loss sharing provision," that, if triggered, may give rise to a contingent obligation that may require the general partners to contribute capital to the fund, to fund 20% of the net losses on investments attributed to the limited partners of such fund. In connection with the "net loss sharing provisions," certain of our private equity vehicles allocate a greater share of their investment losses to us relative to the amounts contributed by us to those vehicles. In these vehicles, such losses would be required to be paid by us to the limited partners in those vehicles in the event of a liquidation of the fund regardless of whether any carried interest had been previously distributed. Based on the fair market values as of December 31, 2012, there would have been no net loss sharing obligation. If the vehicles were liquidated at zero value, the net loss sharing obligation would have been approximately $616.7 million as of December 31, 2012.

        Unlike the "clawback" provisions, the KKR Group Partnerships are responsible for amounts due under net loss sharing arrangements.

Contractual Obligations, Commitments and Contingencies on a Consolidated Basis

        In the ordinary course of business, we and our consolidated funds enter into contractual arrangements that may require future cash payments. The following table sets forth information relating to anticipated future cash payments as of December 31, 2012. This table differs from the table

presented above which sets forth contractual commitments on an unconsolidated basis principally because this table includes the obligations of our consolidated funds.

        The commitment table above excludes contractual amounts owed under the tax receivable agreement because the ultimate amount and timing of the amounts due are not presently known. As of December 31, 2012, a payable of $70.4 million has been recorded in due to affiliates in the consolidated financial statements representing management's best estimate of the amounts currently expected to be owed under the tax receivable agreement. As of December 31, 2012, approximately $2.9 million of cumulative cash payments have been made under the tax receivable agreement. See "—Liquidity Needs—Tax Receivable Agreement".

As of December 31, 2012, the fair value of the contingent consideration obligation was estimated to be $71.3 million. See Note 13 "Acquisitions" in our financial statements included elsewhere in this report.

Off Balance Sheet Arrangements

        Other than contractual commitments and other legal contingencies incurred in the normal course of our business, we do not have any off-balance sheet financings or liabilities.

Consolidated Statement of Cash Flows

        The accompanying consolidated statements of cash flows include the cash flows of our consolidated entities which, in particular, include our consolidated funds notwithstanding the fact that we may hold only a minority economic interest in those funds. The assets of our consolidated funds, on a gross basis, are substantially larger than the assets of our business and, accordingly, have a substantial effect on the cash flows reflected in our consolidated statements of cash flows. The primary cash flow activities of our consolidated funds involve: (i) capital contributions from fund investors; (ii) using the capital of fund investors to make investments; (iii) financing certain investments with indebtedness; (iv) generating cash flows through the realization of investments; and (v) distributing cash flows from the realization of investments to fund investors. Because our consolidated funds are treated as investment companies for accounting purposes, certain of these cash flow amounts are included in our cash flows from operations.

Net Cash Provided by (Used in) Operating Activities

        Our net cash provided by (used in) operating activities was $6.2 billion, $(0.2) billion and $0.7 billion during the years ended December 31, 2012, 2011 and 2010, respectively. These amounts primarily included: (i) proceeds from sales of investments net of purchases of investments by our funds of $5.1 billion, $(0.2) billion and $0.3 billion during the years ended December 31, 2012, 2011 and 2010, respectively; (ii) net realized gains (losses) on investments of $5.2 billion, $3.3 billion and $2.4 billion during the years ended December 31, 2012, 2011 and 2010, respectively; and (iii) change in unrealized gains (losses) on investments of $2.7 billion, $(2.3) billion and $5.3 billion during the years ended December 31, 2012, 2011 and 2010, respectively. Certain KKR funds are, for GAAP purposes, investment companies and reflect their investments and other financial instruments at fair value.

Net Cash Provided by (Used in) Investing Activities

        Our net cash provided by (used in) investing activities was $(220.9) million, $(47.6) million and $(1.3) million during the years ended December 31, 2012, 2011 and 2010, respectively. Our investing activities included the purchases of furniture, computer hardware and leasehold improvements of $37.0 million, $18.2 million and $13.1 million, a (decrease) increase in restricted cash and cash equivalents that primarily funds collateral requirements of $(2.9) million, $29.3 million and $(11.8) million during the years ended December 31, 2012, 2011 and 2010, respectively as well as cash paid for acquisitions, net of cash acquired of $(186.9) million for the year ended December 31, 2012.

Net Cash Provided by (Used in) Financing Activities

        Our net cash provided by (used in) financing activities was $(5.6) billion, $0.4 billion and $(0.5) billion during the years ended December 31, 2012, 2011 and 2010, respectively. Our financing activities primarily included: (i) distributions to, net of contributions by our noncontrolling and redeemable noncontrolling interests, of $(4.9) billion, $0.4 billion and $0.1 billion during the years ended December 31, 2012, 2011 and 2010, respectively; (ii) net proceeds received net of repayment of debt

Critical Accounting Policies

        The preparation of our consolidated financial statements in accordance with GAAP requires our management to make estimates and judgments that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and reported amounts of fees, expenses and investment income. Our management bases these estimates and judgments on available information, historical experience and other assumptions that we believe are reasonable under the circumstances. However, these estimates, judgments and assumptions are often subjective and may be impacted negatively based on changing circumstances or changes in our analyses. If actual amounts are ultimately different from those estimated, judged or assumed, revisions are included in the consolidated financial statements in the period in which the actual amounts become known. We believe the following critical accounting policies could potentially produce materially different results if we were to change underlying estimates, judgments or assumptions. Please see the notes to the consolidated financial statements included elsewhere in this report for further detail regarding our critical accounting policies.

Principles of Consolidation

        Our policy is to consolidate (i) those entities in which we hold a majority voting interest or have majority ownership and control over significant operating, financial and investing decisions of the entity, including those private equity, fixed income, and other investment funds and their respective consolidated funds in which the general partner is presumed to have control or (ii) entities determined to be variable interest entities ("VIEs") for which we are considered the primary beneficiary.

        With respect to the consolidated KKR funds, we generally have operational discretion and control, and limited partners have no substantive rights to impact ongoing governance and operating activities of the fund.

        The consolidated KKR funds do not consolidate their majority owned and controlled investments in portfolio companies. Rather, those investments are accounted for as investments and carried at fair value as described below.

        The KKR funds are consolidated notwithstanding the fact that we have only a minority economic interest in those funds. The consolidated financial statements reflect the assets, liabilities, revenues, expenses, investment income and cash flows of the consolidated KKR funds on a gross basis, and the majority of the economic interests in those funds, which are held by third party investors in our funds, are attributed to noncontrolling interests in the accompanying consolidated financial statements. For funds that are consolidated, all investment income (loss), including the portion of a funds' investment income (loss) that is allocable to KKR's carried interest, is included in investment income (loss) on the consolidated statements of operations. The carried interest that KKR retains in net income (loss) attributable to KKR & Co. L.P. is reflected as an adjustment to net income (loss) attributable to noncontrolling interests. All of the management fees and certain other amounts earned by us from those funds are eliminated in consolidation. However, because the eliminated amounts are earned from, and funded by, noncontrolling interests, our attributable share of the net income from those funds is increased by the amounts eliminated. Accordingly, the elimination in consolidation of such amounts has no effect on net income (loss) attributable to us or our partners' capital.

        Noncontrolling interests represent the ownership interests held by entities or persons other than us.

Fair Value Measurements

For the purposes of the discussion under this subsection "Fair Value Measurements":

Private Equity—Consists primarily of investments in portfolio companies of KKR funds and investments in infrastructure, natural resources and real estate.

Fixed Income—Consists primarily of investments in below investment grade corporate debt securities (primarily high yield bonds and syndicated bank loans), distressed and opportunistic debt and interests in collateralized loan obligations.

Other—Consists primarily of investments in common stock, preferred stock, warrants and options of companies that are not private equity or fixed income investments.

        Investments and other financial instruments are measured and carried at fair value. The majority of investments and other financial instruments are held by the consolidated KKR funds. The KKR funds are, for GAAP purposes, investment companies and reflect their investments and other financial instruments at fair value. KKR has retained the specialized accounting for the consolidated KKR funds in consolidation. Accordingly, the unrealized gains and losses resulting from changes in fair value of the investments held by the KKR funds are reflected as a component of net gains (losses) from investment activities in the consolidated statements of operations.

        For investments and certain other financial instruments that are not held in a consolidated KKR fund, KKR has elected the fair value option since these investments and other financial instruments are similar to those in the consolidated KKR funds. Such election is irrevocable and is applied on an investment by investment basis at initial recognition. Unrealized gains and losses resulting from changes in fair value are reflected as a component of net gains (losses) from investment activities in the consolidated statements of operations. The methodology for measuring the fair value of such investments and other financial instruments is consistent with the methodology applied to investments and other financial instruments that are held in consolidated KKR funds.

        Investments in unconsolidated investment vehicles are accounted for using the equity method of accounting. Under the equity method of accounting, KKR's share of earnings (losses) from equity method investments is included in investment income (loss) on the consolidated statements of operations. The carrying amounts of equity method investments are reflected in investments on the consolidated statements of financial condition. Because the underlying investments of unconsolidated investment vehicles are reported at fair value, the carrying value of KKR's equity method investments approximates fair value.

        The carrying amounts of other assets, accounts payable, accrued expenses and other liabilities recognized on the statements of financial condition (excluding goodwill, intangible assets, contingent consideration and certain debt obligations) approximate fair value due to their short term maturities. See Note 14 "Goodwill and Intangible Assets" in our financial statements included elsewhere in this report for further information on Goodwill and Intangible Assets. See Note 13 "Acquisitions" in our financial statements included elsewhere in this report for further information on contingent consideration. KKR's debt obligations, except for KKR's 2020 Senior Notes, bear interest at floating rates and therefore fair value approximates carrying value. The fair value for KKR's 2020 Senior Notes was derived using Level II inputs similar to those utilized in valuing fixed income investments.

        Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation techniques are applied. These valuation techniques involve varying levels of management estimation and judgment, the degree of which is dependent on a variety of factors. Assets and liabilities recorded at fair value in the consolidated

141

Table of Contents

statements of financial condition are categorized based upon the level of judgment associated with the inputs used to measure their value. Hierarchical levels, as defined under GAAP, are directly related to the amount of subjectivity associated with the inputs to the valuation of these assets and liabilities. The hierarchical levels defined under GAAP are as follows from highest to lowest:

Level I

        Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. The type of investments and other financial instruments included in this category are publicly-listed equities and debt, and securities sold short. We classified 21.4% of total investments measured and reported at fair value as Level I at December 31, 2012.

Level II

        Inputs are other than quoted prices that are observable for the asset or liability, either directly or indirectly. Level II inputs include quoted prices for similar instruments in active markets, and inputs other than quoted prices that are observable for the asset or liability. The type of investments and other financial instruments included in this category are fixed income investments, convertible debt securities indexed to publicly-listed securities, and certain over-the-counter derivatives. We classified 6.2% of total investments measured and reported at fair value as Level II at December 31, 2012.

Level III

        Inputs are unobservable for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. The types of assets and liabilities generally included in this category are private portfolio companies and fixed income investments for which a sufficiently liquid trading market does not exist. We classified 72.4% of total investments measured and reported at fair value as Level III at December 31, 2012. The valuation of our Level III investments at December 31, 2012 represents management's best estimate of the amounts that we would anticipate realizing on the sale of these investments at such date.

        In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. KKR's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the asset.

        A significant decrease in the volume and level of activity for the asset or liability is an indication that transactions or quoted prices may not be representative of fair value because in such market conditions there may be increased instances of transactions that are not orderly. In those circumstances, further analysis of transactions or quoted prices is needed, and a significant adjustment to the transactions or quoted prices may be necessary to estimate fair value.

        The availability of observable inputs can vary depending on the financial asset or liability and is affected by a wide variety of factors, including, for example, the type of instrument, whether the instrument has recently been issued, whether the instrument is traded on an active exchange or in the secondary market, and current market conditions. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by KKR in determining fair value is greatest for instruments categorized in Level III. The variability and availability of the observable inputs affected by the factors described above may cause transfers between Levels I, II, and III, which KKR recognizes at the beginning of the reporting period.

142

Table of Contents

        Investments and other financial instruments that have readily observable market prices (such as those traded on a securities exchange) are stated at the last quoted sales price as of the reporting date. KKR does not adjust the quoted price for these investments, even in situations where KKR holds a large position and a sale could reasonably affect the quoted price.

Level II Valuation Methodologies

        Financial assets and liabilities categorized as Level II consist primarily of debt securities indexed to publicly-listed securities and fixed income and other investments. Fixed income investments generally have bid and ask prices that can be observed in the marketplace. Bid prices reflect the highest price that KKR and others are willing to pay for an asset. Ask prices represent the lowest price that KKR and others are willing to accept for an asset. For financial assets and liabilities whose inputs are based on bid-ask prices obtained from third party pricing services, fair value may not always be a predetermined point in the bid-ask range. KKR's policy is to allow for mid-market pricing and adjusting to the point within the bid-ask range that meets KKR's best estimate of fair value. For debt securities indexed to publicly listed securities, such as convertible debt, the securities are typically valued using standard convertible security pricing models. The key inputs into these models that require some amount of judgment are the credit spreads utilized and the volatility assumed. To the extent the company being valued has other outstanding debt securities that are publicly-traded, the implied credit spread on the company's other outstanding debt securities would be utilized in the valuation. To the extent the company being valued does not have other outstanding debt securities that are publicly-traded, the credit spread will be estimated based on the implied credit spreads observed in comparable publicly-traded debt securities. In certain cases, an additional spread will be added to reflect an illiquidity discount due to the fact that the security being valued is not publicly-traded. The volatility assumption is based upon the historically observed volatility of the underlying equity security into which the convertible debt security is convertible and/or the volatility implied by the prices of options on the underlying equity security.

Level III Valuation Methodologies

        The majority of our Level III investments are private equity investments that are valued utilizing unobservable pricing inputs. Management's determination of fair value is based upon the best information available for a given circumstance and may incorporate assumptions that are management's best estimates after consideration of a variety of internal and external factors. We generally employ two valuation methodologies when determining the fair value of a private equity investment. The first methodology is typically a market comparables analysis that considers key financial inputs and recent public and private transactions and other available measures including EBITDA multiples and control premiums. Other measures are also used in arriving at a market comparables valuation including illiquidity discounts, the presence of significant unconsolidated assets and liabilities and any favorable or unfavorable tax attributes. The second methodology utilized is typically a discounted cash flow analysis, which incorporates significant assumptions and judgments. Estimates of key inputs used in this methodology include the weighted average cost of capital for the investment and assumed inputs used to calculate terminal values, such as exit EBITDA multiples. Other inputs are also used in the discounted cash flow methodology and include assumed growth rates, capital structure, risk premiums and other factors, including, if applicable, factors relating to our estimation of the most likely buyer or market participant for a hypothetical monetization event, which might include public equity offerings or a sale to a private equity investor or a strategic buyer. Also, as discussed in greater detail under "—Business Environment," a change in interest rates could have a significant impact on valuations. In certain cases the results of the discounted cash flow approach can be significantly impacted by these estimates. Upon completion of the valuations conducted using the market comparables methodology and the discounted cash flow methodology, a weighting is ascribed to each method. The ultimate fair value recorded for a particular investment will generally be within the range suggested by the two

143

Table of Contents

methodologies. When determining the weighting ascribed to each valuation methodology, KKR considers, among other factors, the availability of direct market comparables, the applicability of a discounted cash flow analysis and the expected hold period and manner of realization for the investment. These factors can result in different weightings among investments in our portfolio and in certain instances may result in up to a 100% weighting to a single methodology. Across our Level III private equity investment portfolio, approximately 77% of the fair value is derived from investments that are valued based exactly 50% on market comparables and 50% on a discounted cash flow analysis. Less than 5% of the fair value of our private markets investment portfolio is derived from investments that are valued either based 100% on market comparables or 100% on a discounted cash flow analysis. As of December 31, 2012, the weights ascribed to the market comparables methodology and the discounted cash flow methodology for our Level III private equity investments were 47% and 53%, respectively. As of December 31, 2012, we believe that the approach of using both the market multiples methodology and the discounted cash flow methodology resulted in valuations of our aggregate Level III private equity portfolio that were generally lower than if only the discounted cash flow methodology had been used and that were generally higher than if only the market comparables methodology had been used. In addition, an illiquidity discount is typically applied where appropriate. When determining the illiquidity discount applied, KKR evaluates each private equity investment to determine if factors exist that could make it more challenging to monetize the investment in the near-term and, therefore, justify applying a higher illiquidity discount. These factors include whether KKR lacks the unilateral ability to sell the portfolio company or take the portfolio company public, whether the portfolio company is currently engaged in significant restructuring activities, the size of the portfolio company, and whether the company is experiencing, or expected to experience, a significant decline in earnings. Depending on the applicability of the criteria, KKR determines the amount of the illiquidity discount to be applied.

        Our Level III fixed income investments are valued using values obtained from dealers or market makers, and where these values are not available, fixed income investments are valued by KKR using internally developed valuation models. Valuation models are based on discounted cash flow analyses, for which the key inputs are determined based on market comparables, which incorporate similar instruments from similar issuers. As discussed above and in the notes to our financial statements, we utilize several unobservable pricing inputs and assumptions in determining the fair value of our Level III investments. These unobservable pricing inputs and assumptions may differ by investment and in the application of our valuation methodologies. Our reported fair value estimates could vary materially if we had chosen to incorporate different unobservable pricing inputs and other assumptions or, for applicable investments, if we only used either the discounted cash flow methodology or the market comparables methodology instead of assigning a weighting to both methodologies.

Level III Valuation Process

        The valuation process involved for Level III measurements for private equity, fixed income, and other investments is completed on a quarterly basis and is designed to subject the valuation of Level III investments to an appropriate level of consistency, oversight, and review. For purposes of this discussion, private equity investments include infrastructure, real estate and natural resources investments. KKR has a valuation committee for private equity investments and a valuation committee for fixed income and other investments. The private equity valuation committee may be assisted by subcommittees for example in the valuation of natural resources and real estate investments. Each of the private equity valuation committee and the fixed income valuation committee is assisted by a valuation team, which, except as noted below, is comprised only of employees who are not investment professionals responsible for preparing preliminary valuations or for oversight of any of the investments being valued. The valuation teams for natural resources and real estate investments contain investment professionals who participate in the preparation of preliminary valuations and oversight for those investments. The valuation committees and teams are responsible for coordinating and consistently

Table of Contents

implementing KKR's quarterly valuation policies, guidelines and processes. For investments classified as Level III, investment professionals prepare preliminary valuations based on their evaluation of financial and operating data, company specific developments, market valuations of comparable companies and other factors. These preliminary valuations are reviewed with the investment professionals by the applicable valuation team and are also reviewed by an independent valuation firm engaged by KKR to perform certain procedures in order to assess the reasonableness of KKR's valuations for all Level III investments, except for certain investments other than KKR private equity investments. All preliminary valuations are then reviewed by the applicable valuation committee, and after reflecting any input from their respective valuation committees, the preliminary valuations are presented to a single committee consisting of Senior Principals involved in various aspects of the KKR business. When these valuations are approved by this single committee after reflecting any input from it, the valuations of Level III investments, as well as the valuations of Level I and Level II investments, are presented to the audit committee of KKR's board of directors and are then reported on to the board of directors.

        As of December 31, 2012, upon completion by the independent valuation firm of certain limited procedures requested to be performed by them, the independent valuation firm concluded that the fair values, as determined by KKR, of the investments reviewed by them were reasonable. The limited procedures did not involve an audit, review, compilation or any other form of examination or attestation under generally accepted auditing standards and were not conducted on certain Level III fixed income investments. We are responsible for determining the fair value of investments in good faith, and the limited procedures performed by an independent valuation firm are supplementary to the inquiries and procedures that we are required to undertake to determine the fair value of the commensurate investments.

        As described above, Level II and Level III investments were valued using internal models with significant unobservable inputs and our determinations of the fair values of these investments may differ materially from the values that would have resulted if readily observable inputs had existed. Additional external factors may cause those values, and the values of investments for which readily observable inputs exist, to increase or decrease over time, which may create volatility in our earnings and the amounts of assets and partners' capital that we report from time to time.

        Changes in the fair value of the investments of our consolidated private equity funds may impact the net gains (losses) from investment activities of our private equity funds as described under "—Key Financial Measures—Investment Income (Loss)—Net Gains (Losses) from Investment Activities." Based on the investments of our private equity funds as of December 31, 2012, we estimate that an immediate 10% decrease in the fair value of the funds' investments generally would result in a commensurate change in the amount of net gains (losses) from investment activities (except that carried interest would likely be more significantly impacted), regardless of whether the investment was valued using observable market prices or management estimates with significant unobservable pricing inputs. The impact that the consequential decrease in investment income would have on net income attributable to KKR would generally be significantly less than the amount described above, given that a majority of the change in fair value would be attributable to noncontrolling interests and therefore we are only impacted to the extent of our carried interest and our principal investments.

        As of December 31, 2012, private equity investments which represented greater than 5% of the net assets of consolidated private equity investments included: (i) Alliance Boots GmbH valued at $3.5 billion and (ii) HCA, Inc. valued at $2.1 billion.

Revenue Recognition

        Fees consist primarily of (i) monitoring and consulting fees from providing advisory and other services, (ii) management and incentive fees from providing investment management services to unconsolidated funds, a specialty finance company, structured finance and other vehicles, and

145

---

Table of Contents

separately managed accounts, and (iii) transaction fees earned in connection with successful investment transactions and from capital markets activities. These fees are based on the contractual terms of the governing agreements and are recognized when earned, which coincides with the period during which the related services are performed. Monitoring fees may provide for a termination payment following an initial public offering or change of control. These termination payments are recognized in the period when the related transaction closes.

        Certain of KKR's private equity funds require the management company to refund up to 20% of any cash management fees earned from limited partners in the event that the funds recognize a carried interest. At such time as the fund recognizes a carried interest in an amount sufficient to cover 20% of the cash management fees earned or a portion thereof, a liability to the fund's limited partners is recorded and revenue is reduced for the amount of the carried interest recognized, not to exceed 20% of the cash management fees earned. As of December 31, 2012, there is no carried interest subject to management fee refunds, which may reduce carried interest in future periods. The refunds to the limited partners are paid, and the liabilities relieved, at such time that the underlying investments are sold and the associated carried interests are realized. In the event that a fund's carried interest is not sufficient to cover any of the amount that represents 20% of the cash management fees earned, these fees would not be returned to the funds' limited partners, in accordance with the respective fund agreements.

Recognition of Investment Income

        Investment income consists primarily of the net impact of: (i) realized and unrealized gains and losses on investments, (ii) dividends, (iii) interest income, (iv) interest expense and (v) foreign exchange gains and losses relating to mark-to-market activity on foreign exchange forward contracts, foreign currency options and foreign denominated debt. Unrealized gains or losses result from changes in fair value of investments during the period and are included in net gains (losses) from investment activities. Upon disposition of an investment, previously recognized unrealized gains or losses are reversed and a realized gain or loss is recognized. While this reversal generally does not significantly impact the net amounts of gains (losses) that we recognize from investment activities, it affects the manner in which we classify our gains and losses for reporting purposes.

        Due to the consolidation of the majority of our funds, the portion of our funds' investment income that is allocable to our carried interests and capital investments is not shown in the consolidated financial statements. For funds that are consolidated, all investment income (loss), including the portion of a funds' investment income (loss) that is allocable to KKR's carried interest, is included in investment income (loss) on the consolidated statements of operations. The carried interest that KKR retains in net income (loss) attributable to KKR & Co. L.P. is reflected as an adjustment to net income (loss) attributable to noncontrolling interests. Because the substantial majority of our funds are consolidated and because we hold only a minority economic interest in our funds' investments, our share of the investment income generated by our funds' investment activities is significantly less than the total amount of investment income presented in the consolidated financial statements.

Recognition of Carried Interest in Statement of Operations

        Carried interest entitles the general partner of a fund to a greater allocable share of the fund's earnings from investments relative to the capital contributed by the general partner and correspondingly reduces noncontrolling interests' attributable share of those earnings. Amounts earned pursuant to carried interest are included as investment income (loss) in net gains (losses) from investment activities and are earned by the general partner of those funds to the extent that cumulative investment returns are positive and where applicable, preferred return thresholds have been met. If these investment returns decrease or turn negative in subsequent periods, recognized carried interest will be reversed and reflected as investment losses in net gains (losses) from investment activities.

146

Table of Contents

Carried interest is recognized in the statement of operations based on the contractual conditions set forth in the agreements governing the fund as if the fund were terminated and liquidated at the reporting date and the fund's investments were realized at the then estimated fair values. Amounts earned pursuant to carried interest are earned by the general partner of those funds to the extent that cumulative investment returns are positive and where applicable, preferred return thresholds have been met. If these investment amounts earned decrease or turn negative in subsequent periods, recognized carried interest will be reversed and to the extent that the aggregate amount of carry distributions received by the general partner during the term of the fund exceed the amount to which the general partner was ultimately entitled, a clawback obligation would be recorded. For funds that are consolidated, this clawback obligation, if any, is reflected as an increase in noncontrolling interests in the consolidated statements of financial condition. For funds that are not consolidated, this clawback obligation, if any, is reflected as a reduction of our investment balance as this is where carried interest is initially recorded. Due to the extended durations of our private equity funds, we believe that this approach results in income recognition that best reflects our periodic performance in the management of those funds.

Clawback Provision

        The instruments governing our private equity funds generally include a "clawback" provision. Under a "clawback" provision, upon the liquidation of a private equity fund, the general partner is required to return, on an after-tax basis, previously distributed carry to the extent that, due to the diminished performance of later investments, the aggregate amount of carry distributions received by the general partner during the term of the fund exceed the amount to which the general partner was ultimately entitled.

        Certain KKR principals who received carried interest distributions prior to October 1, 2009 with respect to the private equity funds had personally guaranteed, on a several basis and subject to a cap, the contingent obligations of the general partners of the private equity funds to repay amounts to fund limited partners pursuant to the general partners' clawback obligations. KKR principals are responsible for clawback obligations relating to carry distributions received prior to October 1, 2009 up to a maximum of $223.6 million.

        Carry distributions arising subsequent to October 1, 2009 are allocated generally to carry pool participants and the KKR Group Partnerships.

        Our other investment vehicles, including mezzanine, infrastructure and special situations, generally include clawback provisions; however, no distributions of carried interest have been made with respect to these vehicles as of December 31, 2012.

Net Loss Sharing Provision

        The instruments governing certain of our private equity funds may also include a "net loss sharing provision," that, if triggered, may give rise to a contingent obligation that may require the general partners to contribute capital to the fund, to fund 20% of the net losses on investments. In connection with the "net loss sharing provisions," certain of our private equity funds allocate a greater share of their investment losses to us relative to the amounts contributed by us to those vehicles. In these vehicles, such losses would be required to be paid to the limited partners in those vehicles in the event of a liquidation of the fund regardless of whether any carried interest had previously been distributed. Unlike the "clawback" provisions, we will be responsible for amounts due under net loss sharing arrangements and will indemnify our principals for personal guarantees that they have provided with respect to such amounts.

Recently Issued Accounting Pronouncements

Fair Value Measurements

        In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2011-04, "Fair Value Measurement" ("ASU 2011-04"), which amended Accounting Standards Codification (ASC) 820 to clarify existing guidance and minimize differences between U.S. GAAP and International Financial Reporting Standards (IFRS). ASU 2011-04 requires entities to provide information about valuation techniques and unobservable inputs used in Level III fair value measurements and provide additional disclosures for classes of assets and liabilities disclosed at fair value. As a result of adopting ASU 2011-04, KKR has expanded its fair value disclosures. See section "Fair Value Measurements" above and Note 5 "Fair Value Measurements".

Presentation of Comprehensive Income

        In June 2011, the FASB issued Accounting Standards Update No. 2011-05, "Statement of Comprehensive Income" ("ASU 2011-05"), which requires entities to present net income and other comprehensive income in either a single continuous statement or in two separate, but consecutive, statements of net income and other comprehensive income. ASU 2011-05 was effective for KKR's fiscal year beginning January 1, 2012. The standard did not impact our reported results of operations but did impact our financial statement presentation. KKR has adopted the presentation of total comprehensive income in two consecutive statements. See the consolidated statements of operations and consolidated statements of comprehensive income (loss).

Disclosures About Offsetting Assets and Liabilities

        In December 2011, the FASB issued ASU 2011-11, "Disclosures about Offsetting Assets and Liabilities" ("ASU 2011-11"), which requires entities to disclose information about offsetting and related arrangements of financial instruments and derivative instruments. In February 2013, the FASB issued ASU 2013-01, which clarifies which instruments and transactions are subject to the offsetting disclosure requirements established by ASU 2011-11.

        The guidance is effective for KKR's fiscal year beginning January 1, 2013 and is to be applied retrospectively. The adoption of this guidance, which is related to disclosure only, is not expected to have a material impact on KKR's consolidated financial statements.

Disclosures About Reclassification Adjustments Out of Accumulated Other Comprehensive Income

        In February 2013, the FASB issued ASU 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("AOCI")," which requires entities to disclose additional information about reclassification adjustments, including (i) changes in AOCI balances by component and (ii) significant items reclassified out of AOCI. The guidance is effective for KKR's fiscal year beginning January 1, 2013 and is to be applied prospectively. The adoption of this guidance is not expected to have a material impact on KKR's consolidated financial statements.

        In July 2012, the FASB issued ASU 2012-02, "Intangibles—Goodwill and Other," which provides the option to perform a qualitative, rather than quantitative, assessment to determine whether it is more likely than not an indefinite-lived intangible asset is impaired. If the asset is considered impaired, an entity is required to perform the quantitative assessment under the existing guidance. The guidance is effective for KKR's fiscal year beginning January 1, 2013. The adoption of this guidance, which is intended to simplify the impairment testing, is not expected to have a material impact on KKR's financial statements.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        Our exposure to market risks primarily relates to our role as general partner or manager of our funds and sensitivities to movements in the fair value of their investments, including the effect that those movements have on the management fees and carried interests that we receive. We have an increased exposure to market risks as a result of our principal assets. The fair value of investments may fluctuate in response to changes in the values of securities, foreign currency exchange rates and interest rates.

        We manage and monitor risks through several committees. With respect to the funds and other investment vehicles through which we make investments for our fund investors, we manage risk by subjecting transactions to the review and approval of an applicable investment committee, and then a portfolio management committee (or other applicable senior employees) regularly monitors these investments. Before making an investment, investment professionals identify risks in due diligence, evaluating, among other things, business, financial, legal and regulatory issues, financial data and other information. An investment team presents the investment and its identified risks to an investment committee, which must approve each investment before it may be made. If an investment is made, a portfolio management committee (or other applicable senior employees) is responsible for working with our investment professionals to monitor the investment on an ongoing basis.

Market Risk

        Our funds hold investments that are reported at fair value. Net changes in the fair value of investments impact the net gains (losses) from investment activities in our consolidated statements of operations. Based on the investments of our funds as of December 31, 2012, we estimate that an immediate 10% decrease in the fair value of the funds' investments generally would result in a commensurate change in the amount of net gains (losses) from investment activities (except that carried interest would likely be more significantly impacted), regardless of whether the investment was valued using observable market prices or management estimates with significant unobservable pricing inputs. The impact that the consequential decrease in investment income would have on net income attributable to KKR would generally be significantly less than the amount described above, given that a majority of the change in fair value would be attributable to noncontrolling interests and therefore we are only impacted to the extent of our carried interest and our principal investments.

        Our base management fees in our Private Markets investment funds are generally calculated based on the amount of capital committed or invested by a fund, as described under "Business—Our Segments—Private Markets." In the case of our Public Markets business, management fees are often calculated based on the average NAV of the fund, vehicle, or specialty finance company, for that particular period, although certain funds in our Public Markets segment have management fees based on the amount of capital committed or invested. To the extent that base management fees are calculated based on the NAV of the fund's investments, the amount of fees that we may charge will be increased or decreased in direct proportion to the effect of changes in the fair value of the fund's investments. The proportion of our management and other amounts that are based on NAV depends on the number and type of funds in existence. Currently, a majority of our private equity funds are based on a percentage of committed or invested capital.

Securities Market Risk

        Our investment funds make certain investments in portfolio companies whose securities are publicly traded. The market prices of securities may be volatile and are likely to fluctuate due to a number of factors beyond our control. These factors include actual or anticipated fluctuations in the quarterly and annual results of such companies or of other companies in the industries in which they operate, market perceptions concerning the availability of additional securities for sale, general

149

---

Table of Contents

economic, social or political developments, industry conditions, changes in government regulation, shortfalls in operating results from levels forecasted by securities analysts, the general state of the securities markets and other material events, such as significant management changes, re-financings, acquisitions and dispositions. In addition, although our Private Markets investment funds primarily hold investments in portfolio companies whose securities are not publicly traded, the value of these investments may also fluctuate due to similar factors beyond our control as described above for portfolio companies whose securities are publicly traded.

Exchange Rate Risk

        Our investment funds make investments from time to time in currencies other than those in which their capital commitments are denominated. Those investments expose us and our fund investors to the risk that the value of the investments will be affected by changes in exchange rates between the currency in which the capital commitments are denominated and the currency in which the investments are made. Our policy is to minimize these risks by employing hedging techniques, including using foreign currency options and foreign exchange contracts to reduce exposure to future changes in exchange rates when our funds have invested a meaningful amount of capital in currencies other than the currencies in which their capital commitments are denominated.

        Because most of the capital commitments to our funds are denominated in U.S. dollars, our primary exposure to exchange rate risk relates to movements in the value of exchange rates between the U.S. dollar and other currencies in which our investments are denominated (primarily euros, British pounds and Korean won). We estimate that a simultaneous parallel movement by 10% in the exchange rates between the U.S. dollar and all of the major foreign currencies in which our funds' investments were denominated as of December 31, 2012 would result in net gains or losses from investment activities of our funds of $846.7 million. However, we estimate that the effect on net income (loss) attributable to KKR & Co. L.P. from such a change would be significantly less than the amount presented above, because a substantial majority of the gain or loss would be attributable to noncontrolling interests in our funds.

Credit Risk

        We are party to agreements providing for various financial services and transactions that contain an element of risk in the event that the counterparties are unable to meet the terms of such agreements. In these agreements, we depend on these counterparties to make payment or otherwise perform. We generally endeavor to minimize our risk of exposure by limiting the counterparties with which we enter into financial transactions to reputable financial institutions. In addition, availability of financing from financial institutions may be uncertain due to market events, and we may not be able to access these financing markets.

Interest Rate Risk

        We and our consolidated funds have debt obligations that include revolving credit agreements and certain investment financing arrangements structured through the use of term loans and revolving credit facilities that accrue interest at variable rates, and changes in these rates would affect the amount of interest payments that we would have to make, impacting future earnings and cash flows. Based on our debt obligations payable at December 31, 2012 (inclusive of debt obligations of our consolidated funds), we estimate that interest expense relating to instruments bearing variable rates would increase on an annual basis by $6.3 million in the event interest rates were to increase by 100 basis points. The estimated impact on interest expense is solely on the debt obligations of our consolidated funds.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Unitholders of KKR & Co. L.P.:

        We have audited the accompanying consolidated statements of financial condition of KKR & Co. L.P. and subsidiaries (the "Company") as of December 31, 2012 and 2011, and the related consolidated statements of operations, comprehensive income, changes in equity, and cash flows for each of the three years in the period ended December 31, 2012. We also have audited the Company's internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. As described in Management's Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Prisma Capital Partners LP. and its affiliates (collectively, "Prisma"), acquired on October 1, 2012, as the Company is in the process of evaluating the internal controls of the acquired business. Prisma represents approximately 0.6% of the total consolidated assets and approximately 3.0% of the total consolidated fees of the Company as of and for the fiscal year ended December 31, 2012. Accordingly, our audit did not include the internal control over financial reporting at Prisma. The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on these financial statements and an opinion on the Company's internal control over financial reporting based on our audits.

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

        A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorization of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of the inherit limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation

152

of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of KKR & Co. L.P. and subsidiaries as of December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2012, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

1. ORGANIZATION

        KKR & Co. L.P. (NYSE:KKR), together with its consolidated subsidiaries ("KKR"), is a leading global investment firm that offers a broad range of investment management services to fund investors and provides capital markets services for the firm, its portfolio companies and third parties. Led by Henry Kravis and George Roberts, KKR conducts business with offices around the world, which provides a global platform for sourcing transactions, raising capital and carrying out capital markets activities. KKR operates as a single professional services firm and carries out its investment activities under the KKR brand name.

        KKR & Co. L.P. was formed as a Delaware limited partnership on June 25, 2007 and its general partner is KKR Management LLC (the "Managing Partner"). KKR & Co. L.P. is the parent company of KKR Group Limited, which is the non-economic general partner of KKR Group Holdings L.P. ("Group Holdings"), and KKR & Co. L.P. is the sole limited partner of Group Holdings. Group Holdings holds a controlling economic interest in each of (i) KKR Management Holdings L.P. ("Management Holdings") through KKR Management Holdings Corp., a Delaware corporation which is a domestic corporation for U.S. federal income tax purposes, and (ii) KKR Fund Holdings L.P. ("Fund Holdings" and together with Management Holdings, the "KKR Group Partnerships") directly and through KKR Fund Holdings GP Limited, a Cayman Island limited company which is a disregarded entity for U.S. federal income tax purposes. Group Holdings also owns certain economic interests in Management Holdings through a wholly owned Delaware corporate subsidiary of KKR Management Holdings Corp. and certain economic interests in Fund Holdings through a Delaware partnership of which Group Holdings is the general partner with a 99% economic interest and KKR Management Holdings Corp. is a limited partner with a 1% economic interest. KKR & Co. L.P., through its indirect controlling economic interests in the KKR Group Partnerships, is the holding partnership for the KKR business.

        KKR & Co. L.P. both indirectly controls the KKR Group Partnerships and indirectly holds equity units in each KKR Group Partnership (collectively, "KKR Group Partnership Units") representing economic interests in KKR's business. The remaining KKR Group Partnership Units are held by KKR's principals through KKR Holdings L.P. ("KKR Holdings"), which is not a subsidiary of KKR. As of December 31, 2012, KKR & Co. L.P. held 36.9% of the KKR Group Partnership Units and KKR's principals held 63.1% of the KKR Group Partnership Units through KKR Holdings. The percentage ownership in the KKR Group Partnerships will continue to change as KKR Holdings and/or KKR's principals exchange units in the KKR Group Partnerships for KKR & Co. L.P. common units.

        The following table presents the effect of changes in the ownership interest in the KKR Group Partnerships on KKR & Co. L.P.'s equity:

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting

        The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").

        The consolidated financial statements (referred to hereafter as the "financial statements") include the accounts of KKR's management and capital markets companies, the general partners of certain unconsolidated funds, general partners of consolidated funds and their respective consolidated funds (the "KKR Funds") and certain other entities.

        KKR consolidates the financial results of the KKR Group Partnerships and their consolidated subsidiaries. KKR Holdings' ownership interest in the KKR Group Partnerships is reflected as noncontrolling interests in the accompanying financial statements.

        References in the accompanying financial statements to KKR's "principals" are to KKR's senior employees and non-employee operating consultants who hold interests in KKR's business through KKR Holdings, including those principals who also hold interests in the Managing Partner entitling those principals to vote for the election of the Managing Partners' directors (the "Senior Principals").

Use of Estimates

        The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of fees, expenses and investment income (loss) during the reporting periods. Such estimates include but are not limited to the valuation of investments and financial instruments. Actual results could differ from those estimates, and such differences could be material to the financial statements.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Consolidation

General

        KKR consolidates (i) those entities in which it holds a majority voting interest or has majority ownership and control over significant operating, financial and investing decisions of the entity, including the KKR Funds in which KKR, as general partner, is presumed to have control, or (ii) entities determined to be variable interest entities ("VIEs") for which KKR is considered the primary beneficiary.

        With respect to the consolidated KKR Funds, KKR generally has operational discretion and control, and limited partners have no substantive rights to impact ongoing governance and operating activities of the fund. The KKR Funds are consolidated by KKR notwithstanding the fact that KKR has only a minority economic interest in those funds. KKR's financial statements reflect the assets, liabilities, fees, expenses, investment income (loss) and cash flows of the consolidated KKR Funds on a gross basis, and the majority of the economic interests in those funds, which are held by third party fund investors, are attributed to noncontrolling interests in the accompanying financial statements. All of the management fees and certain other amounts earned by KKR from those funds are eliminated in consolidation. However, because the eliminated amounts are earned from, and funded by, noncontrolling interests, KKR's attributable share of the net income (loss) from those funds is increased by the amounts eliminated. Accordingly, the elimination in consolidation of such amounts has no effect on net income (loss) attributable to KKR or KKR partners' capital.

        The KKR Funds are, for GAAP purposes, investment companies and therefore are not required to consolidate their investments, including majority-owned and controlled investments in portfolio companies ("Portfolio Companies"). Rather, the KKR Funds reflect their investments at fair value as described in the Fair Value Measurements section. All intercompany transactions and balances have been eliminated.

Variable Interest Entities

        KKR consolidates all VIEs in which it is considered the primary beneficiary. An enterprise is determined to be the primary beneficiary if it has a controlling financial interest under GAAP. A controlling financial interest is defined as (a) the power to direct the activities of a variable interest entity that most significantly impact the entity's business and (b) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the variable interest entity. The consolidation rules which were revised effective January 1, 2010, require an analysis to determine (a) whether an entity in which KKR has a variable interest is a VIE and (b) whether KKR's involvement, through the holding of equity interests directly or indirectly in the entity or contractually through other variable interests unrelated to the holding of equity interests, would give it a controlling financial interest under GAAP. Performance of that analysis requires the exercise of judgment. Where KKR has an interest in an entity that has qualified for the deferral of the consolidation rules, the analysis is based on consolidation rules prior to January 1, 2010. These rules require an analysis to determine (a) whether an entity in which KKR has a variable interest is a VIE and (b) whether KKR's involvement, through the holding of equity interests directly or indirectly in the entity or contractually through other variable interests would be expected to absorb a majority of the

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

variability of the entity. Under both guidelines, KKR determines whether it is the primary beneficiary of a VIE at the time it becomes involved with a VIE and reconsiders that conclusion at each reporting date. In evaluating whether KKR is the primary beneficiary, KKR evaluates its economic interests in the entity held either directly by KKR or indirectly through related parties. The consolidation analysis can generally be performed qualitatively; however, if it is not readily apparent that KKR is not the primary beneficiary, a quantitative analysis may also be performed. Investments and redemptions (either by KKR, affiliates of KKR or third parties) or amendments to the governing documents of the respective entities could affect an entity's status as a VIE or the determination of the primary beneficiary. At each reporting date, KKR assesses whether it is the primary beneficiary and will consolidate or deconsolidate accordingly. KKR's accounting conclusion under the existing consolidation rules determined that effective January 1, 2011, KKR became the primary beneficiary of certain entities and consolidated such entities that were unconsolidated prior to that date.

        As of December 31, 2012 and 2011, the maximum exposure to loss for those VIEs in which KKR is determined not to be the primary beneficiary but in which it has a variable interest is as follows:

        For those unconsolidated VIEs in which KKR is the sponsor, KKR may have an obligation as general partner to provide commitments to such funds. For years ended December 31, 2012, 2011 and 2010, KKR did not provide any support other than its obligated amount.

        KKR's investment strategies differ by investment fund; however, the fundamental risks have similar characteristics, including loss of invested capital and loss of management fees and carried interests. Accordingly, disaggregation of KKR's involvement with VIEs would not provide more useful information.

Business Combinations

        Acquisitions are accounted for using the acquisition method of accounting. The purchase price of an acquisition is allocated to the assets acquired and liabilities assumed using the estimated fair values at the acquisition date. Transaction costs are expensed as incurred.

Intangible Assets

        Intangible assets consist primarily of contractual rights to earn future fee income, including management and incentive fees, and are included in Other Assets within the statements of financial condition. Identifiable finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives and amortization expense is included within General, Administrative and Other in the accompanying consolidated statements of operations. Intangible assets are reviewed for impairment when circumstances indicate an impairment may exist. KKR does not hold any indefinite-lived intangible assets.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Goodwill

        Goodwill represents the excess of acquisition cost over the fair value of net tangible and intangible assets acquired in connection with an acquisition. Goodwill will be assessed for impairment annually or more frequently if circumstances indicate impairment may have occurred. Goodwill is recorded in Other Assets within the statements of financial condition.

Redeemable Noncontrolling Interests

        Redeemable Noncontrolling Interests represent noncontrolling interests of certain investment vehicles and funds that are subject to periodic redemption by fund investors following the expiration of a specified period of time (typically between one and three years), or may be withdrawn subject to a redemption fee during the period when capital may not be otherwise withdrawn. Limited partner interests subject to redemption as described above are presented as Redeemable Noncontrolling Interests within the consolidated statements of financial condition and presented as Net Income (Loss) attributable to Redeemable Noncontrolling Interests within the consolidated statements of operations. When redeemable amounts become legally payable to fund investors, they are classified as a liability and included in Accounts Payable, Accrued Expenses and Other Liabilities in the consolidated statements of financial condition. For all consolidated investment vehicles and funds in which redemption rights have not been granted, noncontrolling interests are presented within Equity in the consolidated statements of financial condition as Noncontrolling Interests.

Noncontrolling Interests

        Noncontrolling interests represent (i) noncontrolling interests in consolidated entities and (ii) noncontrolling interests held by KKR Holdings.

Noncontrolling Interests in Consolidated Entities

        Noncontrolling interests in consolidated entities represent the non-redeemable ownership interests in KKR that are held primarily by:

(i)

third party fund investors in the KKR Funds;



(ii)

a former principal and such person's designees representing an aggregate of 1% of the carried interest received by the general partners of KKR's funds and 1% of KKR's other profits (losses) until a future date;



(iii)

certain of KKR's former principals and their designees representing a portion of the carried interest received by the general partners of KKR's private equity funds that was allocated to them with respect to private equity investments made during such former principals' previous tenure with KKR;



(iv)

certain of KKR's current and former principals representing all of the capital invested by or on behalf of the general partners of KKR's private equity funds prior to October 1, 2009 and any returns thereon; and

a third party in KKR's capital markets business (representing approximately 2% of the equity in the capital markets business).

Noncontrolling Interests held by KKR Holdings

        Noncontrolling interests held by KKR Holdings include economic interests held by KKR's principals in the KKR Group Partnerships. KKR's principals receive financial benefits from KKR's business in the form of distributions received from KKR Holdings and through their direct and indirect participation in the value of KKR Group Partnership Units held by KKR Holdings. These financial benefits are not paid by KKR and are borne by KKR Holdings.

        The following table presents the calculation of noncontrolling interests held by KKR Holdings:

        Income (loss) attributable to KKR after allocation to noncontrolling interests held by KKR Holdings, with the exception of certain tax assets and liabilities that are directly allocable to KKR Management Holdings Corp., is attributed based on the percentage of the weighted average KKR Group Partnership Units held by KKR and KKR Holdings, each of which hold equity of the KKR Group Partnerships. However, primarily because of the (i) contribution of certain expenses borne entirely by KKR Holdings, (ii) the periodic exchange of KKR Holdings units for KKR & Co. L.P. common units pursuant to the exchange agreement and (iii) the contribution of certain expenses borne entirely by KKR associated with the 2010 Equity Plan, equity allocations shown in the consolidated

statement of changes in equity differ from their respective pro-rata ownership interests in KKR's net assets.

        The following table presents the calculation of Net income (loss) attributable to noncontrolling interests held by KKR Holdings:

Fair Value Measurements

        Investments and other financial instruments are measured and carried at fair value. The majority of investments and other financial instruments are held by the consolidated KKR Funds. The KKR Funds are, for GAAP purposes, investment companies and reflect their investments and other financial instruments at fair value. KKR has retained the specialized accounting for the consolidated KKR Funds in consolidation. Accordingly, the unrealized gains and losses resulting from changes in fair value of the investments held by the KKR Funds are reflected as a component of Net Gains (Losses) from Investment Activities in the consolidated statements of operations.

        For investments and certain other financial instruments that are not held in a consolidated KKR Fund, KKR has elected the fair value option since these investments and other financial instruments are similar to those in the consolidated KKR Funds. Such election is irrevocable and is applied on an investment by investment basis at initial recognition. Unrealized gains and losses resulting from changes in fair value are reflected as a component of Net Gains (Losses) from Investment Activities in the consolidated statements of operations. The methodology for measuring the fair value of such investments and other financial instruments is consistent with the methodologies applied to investments and other financial instruments that are held in consolidated KKR Funds.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

        Investments in unconsolidated investment vehicles are accounted for using the equity method of accounting. Under the equity method of accounting, KKR's share of earnings (losses) from equity method investments is included in investment income (loss) on the consolidated statements of operations. The carrying amounts of equity method investments are reflected in investments on the consolidated statements of financial condition. Because the underlying investments of unconsolidated investment vehicles are reported at fair value, the carrying value of KKR's equity method investments approximates fair value.

        The carrying amounts of Other Assets, Accounts Payable, Accrued Expenses and Other Liabilities recognized on the statements of financial condition (excluding Fixed Assets, Goodwill, Intangible Assets, contingent consideration and certain debt obligations) approximate fair value due to their short term maturities. Further information on Goodwill and Intangible Assets is presented in Note 14 "Goodwill and Intangible Assets." Further information on contingent consideration is presented in Note 13 "Acquisitions." KKR's debt obligations, except for KKR's 2020 Senior Notes, bear interest at floating rates and therefore fair value approximates carrying value. Further information on KKR's 2020 Senior Notes is presented in Note 8, "Debt Obligations." The fair value for KKR's 2020 Senior Notes was derived using Level II inputs similar to those utilized in valuing fixed income investments.

        Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation techniques are applied. These valuation techniques involve varying levels of management estimation and judgment, the degree of which is dependent on a variety of factors. See Note 5, "Fair Value Measurements" for further information on KKR's valuation techniques that involve unobservable inputs. Assets and liabilities recorded at fair value in the statements of financial condition are categorized based upon the level of judgment associated with the inputs used to measure their value. Hierarchical levels, as defined under GAAP, are directly related to the amount of subjectivity associated with the inputs to the valuation of these assets and liabilities. The hierarchical levels defined under GAAP are as follows:

Level I

        Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. The type of investments and other financial instruments included in this category are publicly-listed equities and debt, and securities sold short.

Level II

        Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. Level II inputs include quoted prices for similar instruments in active markets, and inputs other than quoted prices that are observable for the asset or liability. The type of investments and other financial instruments included in this category are fixed income investments, convertible debt securities indexed to publicly-listed securities, and certain over-the-counter derivatives.

Level III

        Inputs are unobservable for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. The types of assets and liabilities generally included in this category are private Portfolio Companies and fixed income investments for which a sufficiently liquid trading market does not exist.

        In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. KKR's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and consideration of factors specific to the asset.

        A significant decrease in the volume and level of activity for the asset or liability is an indication that transactions or quoted prices may not be representative of fair value because in such market conditions there may be increased instances of transactions that are not orderly. In those circumstances, further analysis of transactions or quoted prices is needed, and a significant adjustment to the transactions or quoted prices may be necessary to estimate fair value.

        The availability of observable inputs can vary depending on the financial asset or liability and is affected by a wide variety of factors, including, for example, the type of instrument, whether the instrument has recently been issued, whether the instrument is traded on an active exchange or in the secondary market, and current market conditions. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by KKR in determining fair value is greatest for instruments categorized in Level III. The variability and availability of the observable inputs affected by the factors described above may cause transfers between Levels I, II, and III, which KKR recognizes at the beginning of the reporting period.

        Investments and other financial instruments that have readily observable market prices (such as those traded on a securities exchange) are stated at the last quoted sales price as of the reporting date. KKR does not adjust the quoted price for these investments, even in situations where KKR holds a large position and a sale could reasonably affect the quoted price.

Level II Valuation Methodologies

        Financial assets and liabilities categorized as Level II consist primarily of debt securities indexed to publicly-listed securities and fixed income and other investments. Fixed income investments generally have bid and ask prices that can be observed in the marketplace. Bid prices reflect the highest price that KKR and others are willing to pay for an asset. Ask prices represent the lowest price that KKR and others are willing to accept for an asset. For financial assets and liabilities whose inputs are based on bid-ask prices obtained from third party pricing services, fair value may not always be a predetermined point in the bid-ask range. KKR's policy is to allow for mid-market pricing and adjusting to the point within the bid-ask range that meets KKR's best estimate of fair value. For debt securities indexed to publicly listed securities, such as convertible debt, the securities are typically valued using standard convertible security pricing models. The key inputs into these models that require some

amount of judgment are the credit spreads utilized and the volatility assumed. To the extent the company being valued has other outstanding debt securities that are publicly-traded, the implied credit spread on the company's other outstanding debt securities would be utilized in the valuation. To the extent the company being valued does not have other outstanding debt securities that are publicly-traded, the credit spread will be estimated based on the implied credit spreads observed in comparable publicly-traded debt securities. In certain cases, an additional spread will be added to reflect an illiquidity discount due to the fact that the security being valued is not publicly-traded. The volatility assumption is based upon the historically observed volatility of the underlying equity security into which the convertible debt security is convertible and/or the volatility implied by the prices of options on the underlying equity security.

Level III Valuation Methodologies

        Financial assets and liabilities categorized as Level III consist primarily of the following:

        Private Equity Investments:    KKR generally employs two valuation methodologies when determining the fair value of a private equity investment. The first methodology is typically a market comparables analysis that considers key financial inputs and recent public and private transactions and other available measures. The second methodology utilized is typically a discounted cash flow analysis, which incorporates significant assumptions and judgments. Estimates of key inputs used in this methodology include the weighted average cost of capital for the investment and assumed inputs used to calculate terminal values, such as exit EBITDA multiples. Other inputs are also used.

        Upon completion of the valuations conducted using these methodologies, a weighting is ascribed to each method, and an illiquidity discount is typically applied where appropriate. The ultimate fair value recorded for a particular investment will generally be within a range suggested by the two methodologies.

        When determining the weighting ascribed to each valuation methodology, KKR considers, among other factors, the availability of direct market comparables, the applicability of a discounted cash flow analysis and the expected hold period and manner of realization for the investment. These factors can result in different weightings among investments in the portfolio and in certain instances may result in up to a 100% weighting to a single methodology. Across the Level III private equity investment portfolio, approximately 77% of the fair value is derived from investments that are valued based exactly 50% on market comparables and 50% on a discounted cash flow analysis. Less than 5% of the fair value of the Level III private equity investment portfolio is derived from investments that are valued either based 100% on market comparables or 100% on a discounted cash flow analysis.

        When determining the illiquidity discount applied, KKR evaluates each private equity investment to determine if factors exist that could make it more challenging to monetize the investment in the near-term and, therefore, justify applying a higher illiquidity discount. These factors include whether KKR lacks the unilateral ability to sell the portfolio company or take the portfolio company public, whether the portfolio company is currently engaged in significant restructuring activities, the size of the portfolio company, and whether the company is experiencing, or expected to experience, a significant decline in earnings. Depending on the applicability of the criteria, KKR determines the amount of the illiquidity discount to be applied.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

        Fixed Income Investments:    Fixed income investments are valued using values obtained from dealers or market makers, and where these values are not available, fixed income investments are valued by KKR using internally developed valuation models. Valuation models are based on discounted cash flow analyses, for which the key inputs are determined based on market comparables, which incorporate similar instruments from similar issuers.

        Other Investments:    Other investments primarily represent privately-held equity and equity-like securities (e.g. warrants) in companies that are not private equity or fixed income investments. KKR generally employs the same valuation methodologies as described above for private equity investments when valuing these other investments.

        Key unobservable inputs that have a significant impact on KKR's Level III investment valuations as described above are included in Note 5 "Fair Value Measurements." KKR utilizes several unobservable pricing inputs and assumptions in determining the fair value of its Level III investments. These unobservable pricing inputs and assumptions may differ by investment and in the application of KKR's valuation methodologies. KKR's reported fair value estimates could vary materially if KKR had chosen to incorporate different unobservable pricing inputs and other assumptions or, for applicable investments, if KKR only used either the discounted cash flow methodology or the market comparables methodology instead of assigning a weighting to both methodologies.

Level III Valuation Process

        The valuation process involved for Level III measurements for private equity, fixed income, and other investments is completed on a quarterly basis and is designed to subject the valuation of Level III investments to an appropriate level of consistency, oversight, and review. KKR has a valuation committee for private equity investments and a valuation committee for fixed income and other investments. The private equity valuation committee may be assisted by subcommittees for example in the valuation of natural resources and real estate investments. Each of the private equity valuation committee and the fixed income valuation committee is assisted by a valuation team, which, except as noted below, is comprised only of employees who are not investment professionals responsible for preparing preliminary valuations or for oversight of any of the investments being valued. The valuation teams for natural resources and real estate investments contain investment professionals who participate in the preparation of preliminary valuations and oversight for those investments. The valuation committees and teams are responsible for coordinating and consistently implementing KKR's quarterly valuation policies, guidelines and processes. For investments classified as Level III, investment professionals prepare preliminary valuations based on their evaluation of financial and operating data, company specific developments, market valuations of comparable companies and other factors. These preliminary valuations are reviewed with the investment professionals by the applicable valuation team and are also reviewed by an independent valuation firm engaged by KKR to perform certain procedures in order to assess the reasonableness of KKR's valuations for all Level III investments, except for certain investments other than KKR private equity investments. All preliminary valuations are then reviewed by the applicable valuation committee, and after reflecting any input by their respective valuation committees, the preliminary valuations are presented to a single committee consisting of Senior Principals involved in various aspects of the KKR business. When these valuations are approved by this single committee after reflecting any input from it, the valuations of Level III

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

investments, as well as the valuations of Level I and Level II investments, are presented to the audit committee of KKR's board of directors and are then reported on to the board of directors.

Investments

        Investments consist primarily of private equity, fixed income, and other investments. Investments are carried at their estimated fair values, with unrealized gains or losses resulting from changes in fair value reflected as a component of Net Gains (Losses) from Investment Activities in the consolidated statements of operations. Investments denominated in currencies other than the U.S. dollar are valued based on the spot rate of the respective currency at the end of the reporting period with changes related to exchange rate movements reflected as a component of Net Gains (Losses) from Investment Activities in the accompanying consolidated statements of operations. Security and loan transactions are recorded on a trade date basis. Further disclosure on investments is presented in Note 4, "Investments."

        Private Equity—Consists primarily of investments in Portfolio Companies of KKR Funds and investments in infrastructure, natural resources and real estate.

        Fixed Income—Consists primarily of investments in below investment grade corporate debt securities (primarily high yield bonds and syndicated bank loans), distressed and opportunistic debt and interests in collateralized loan obligations.

        Other—Consists primarily of investments in common stock, preferred stock, warrants and options of companies that are not private equity or fixed income investments.

Securities Sold Short

        Whether part of a hedging transaction or a transaction in its own right, securities sold short represent obligations of KKR to deliver the specified security at the contracted price at a future point in time, and thereby create a liability to repurchase the security in the market at the prevailing prices. The liability for such securities sold short, which is recorded in Accounts Payable, Accrued Expenses and Other Liabilities in the statement of financial condition, is marked to market based on the current fair value of the underlying security at the reporting date with changes in fair value recorded as unrealized gains or losses in Net Gains (Losses) from Investment Activities in the accompanying consolidated statements of operations. These transactions may involve market risk in excess of the amount currently reflected in the accompanying statements of financial condition.

Cash and Cash Equivalents

        KKR considers all highly liquid short-term investments with original maturities of 90 days or less when purchased to be cash equivalents.

Cash and Cash Equivalents Held at Consolidated Entities

        Cash and cash equivalents held at consolidated entities represents cash that, although not legally restricted, is not available to fund general liquidity needs of KKR as the use of such funds is generally limited to the investment activities of the KKR Funds.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Restricted Cash and Cash Equivalents

        Restricted cash and cash equivalents primarily represent amounts that are held by third parties under certain of KKR's financing and derivative transactions.

Due from and Due to Affiliates

        For purposes of classifying amounts, KKR considers its principals and their related entities, unconsolidated funds and the Portfolio Companies of its funds to be affiliates. Receivables from and payables to affiliates are recorded at their current settlement amount.

Fixed Assets, Depreciation and Amortization

        Fixed assets consist primarily of leasehold improvements, furniture and computer hardware. Such amounts are recorded at cost less accumulated depreciation and amortization and are included in Other Assets within the statement of financial condition. Depreciation and amortization are calculated using the straight-line method over the assets' estimated economic useful lives, which for leasehold improvements are the lesser of the lease terms or the life of the asset, and three to seven years for other fixed assets.

Comprehensive Income

        Comprehensive income is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances, excluding those resulting from contributions from and distributions to owners. In the accompanying consolidated financial statements, comprehensive income represents Net Income (Loss), as presented in the consolidated statements of operations and net foreign currency translation adjustments.

Derivatives

        Derivative contracts include forward, swap and option contracts related to foreign currencies and credit standing of reference entities to manage foreign exchange risk and credit risk arising from certain assets and liabilities. All derivatives are recognized in Other Assets or Accounts Payable, Accrued Expenses and Other Liabilities in the consolidated statements of financial condition and measured at fair value with changes in fair value recorded in Net Gains (Losses) from Investment Activities in the accompanying consolidated statements of operations. KKR's derivative financial instruments contain credit risk to the extent that its counterparties may be unable to meet the terms of the agreements. KKR attempts to minimize this risk by limiting its counterparties to major financial institutions with strong credit ratings.

Fees

        Fees consist primarily of (i) monitoring and consulting fees from providing advisory and other services, (ii) management and incentive fees from providing investment management services to unconsolidated funds, a specialty finance company, structured finance and other vehicles, and separately managed accounts, and (iii) transaction fees earned in connection with successful investment transactions and from capital markets activities. These fees are based on the contractual terms of the

governing agreements and are recognized when earned, which coincides with the period during which the related services are performed.

        For the years ended December 31, 2012, 2011 and 2010, fees consisted of the following:

        Substantially all fees presented in the table above are earned from affiliates.

Transaction Fees

        Transaction fees are earned by KKR primarily in connection with successful investment transactions and capital markets activities. Transaction fees are recognized upon closing of the transaction. Fees are typically paid on or around the closing of a transaction.

        In connection with pursuing successful Portfolio Company investments, KKR receives reimbursement for certain transaction-related expenses. Transaction-related expenses, which are reimbursed by third parties, are typically deferred until the transaction is consummated and are recorded in Other Assets on the consolidated statements of financial condition on the date incurred. The costs of successfully completed transactions are borne by the KKR Funds and included as a component of the investment's cost basis. Subsequent to closing, investments are recorded at fair value each reporting period as described in the section above titled "Investments". Upon reimbursement from a third party, the cash receipt is recorded and the deferred amounts are relieved. No fees or expenses are recorded for these reimbursements.

Monitoring and Consulting Fees

        Monitoring fees are earned by KKR for services provided to Portfolio Companies and are recognized as services are rendered. These fees are generally paid based on a fixed periodic schedule by the Portfolio Companies either in advance or in arrears and are separately negotiated for each Portfolio Company.

        In connection with the monitoring of Portfolio Companies and certain unconsolidated funds, KKR receives reimbursement for certain expenses incurred on behalf of these entities. Costs incurred in monitoring these entities are classified as general, administrative and other expenses and reimbursements of such costs are classified as monitoring fees. In addition, certain monitoring fee provisions may provide for a termination payment following an initial public offering or change of control. These termination payments are recognized in the period when the related transaction closes.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

        Consulting fees are earned by certain consolidated entities for consulting services provided to Portfolio Companies and other companies and are recognized as the services are rendered. These fees are separately negotiated with each company for which services are provided.

Management Fees

        Management fees are earned by KKR for management services provided to private equity funds, a specialty finance company, structured finance vehicles and other investment vehicles which are recognized in the period during which the related services are performed in accordance with the contractual terms of the related agreement. Management fees earned from private equity funds and certain investment vehicles are based upon a percentage of capital committed during the investment period, and thereafter based on remaining invested capital. For certain other investment vehicles, structured finance vehicles, separately managed accounts and a specialty finance vehicle, management fees are recognized in the period during which the related services are performed and are based upon the net asset value, gross assets or as otherwise defined in the respective agreements.

        Management fees received from consolidated KKR Funds are eliminated in consolidation. However, because these amounts are funded by, and earned from, noncontrolling interests, KKR's allocated share of the net income from consolidated KKR Funds is increased by the amount of fees that are eliminated. Accordingly, the elimination of these fees does not have an effect on the net income (loss) attributable to KKR or KKR partners' capital.

Private Equity Funds

        For KKR's consolidated and unconsolidated private equity funds, gross management fees generally range from 1% to 2% of committed capital during the fund's investment period and is generally 0.75% of invested capital after the expiration of the fund's investment period with subsequent reductions over time. Typically, an investment period is defined as a period of up to six years. The actual length of the investment period may be shorter based on the timing and deployment of committed capital.

        Certain of KKR's private equity funds require the management company to refund up to 20% of any cash management fees earned from limited partners in the event that the funds recognize a carried interest. At such time as the fund recognizes a carried interest in an amount sufficient to cover 20% of the cash management fees earned or a portion thereof, a liability to the fund's limited partners is recorded and revenue is reduced for the amount of the carried interest recognized, not to exceed 20% of the cash management fees earned. The refunds to the limited partners are paid, and the liabilities relieved, at such time that the underlying investments are sold and the associated carried interests are realized. In the event that a fund's carried interest is not sufficient to cover all or a portion of the amount that represents 20% of the earned cash management fees, these fees would not be returned to the funds' limited partners, in accordance with the respective fund agreements.

KKR Financial Holdings LLC ("KFN")

        KKR's management agreement with KFN entitles KKR to a base management fee. KKR earns a base management fee, computed and payable monthly in arrears, based on an annual rate of 1.75% of adjusted equity, which is an amount defined in the management agreement.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Structured Finance Vehicles

        KKR's management agreements for its structured finance vehicles provide for senior collateral management fees and subordinate collateral management fees. Senior collateral management fees are determined based on an annual rate ranging from 0.15% to 0.20% of collateral and subordinate collateral management fees are determined based on an annual rate ranging from 0.30% to 0.35% of collateral. If amounts distributable on any payment date are insufficient to pay the collateral management fees according to the priority of payments, any shortfall is deferred and payable on subsequent payment dates. KKR has the right to waive all or any portion of any collateral management fee. As of December 31, 2012, KKR has permanently waived $169.3 million of collateral management fees. KKR generally waives the collateral management fees for the majority of its structured finance vehicles; however, KKR may cease waiving collateral management fees at its discretion. For the purpose of calculating the collateral management fees, collateral, the payment dates, and the priority of payments are terms defined in the management agreements.

Other Investment Vehicles

        Certain other investment vehicles that invest capital in (i) leveraged credit strategies, such as leveraged loans and high yield bonds, (ii) liquid long/short equity strategies, (iii) alternative credit strategies such as mezzanine investments, special situations investments and direct senior lending and (iv) hedge funds solutions provide for management fees determined quarterly based on an annual rate generally ranging from 0.5% to 1.5%. Such rate may be based on the investment vehicles average net asset value, capital commitments, or invested capital.

Incentive Fees

KFN

        KKR's management agreement with KFN entitles KKR to quarterly incentive fees. KKR records the KFN performance-based incentive fee, if any, when the performance-based incentive fee becomes fixed and determinable, which is quarterly. The quarterly incentive fee is an amount equal to the product of (i) 25% of the dollar amount by which: (a) KFN's net income, before incentive compensation, per weighted average share of KFN's common shares for such quarter, exceeds (b) an amount equal to (A) the weighted average of the price per share of the common stock of KFN in its August 2004 private placement and the prices per share of the common stock of KFN in its initial public offering and any subsequent offerings by KFN multiplied by (B) the greater of (1) 2.00% and (2) 0.50% plus one-fourth of the ten year treasury rate for such quarter, multiplied by (ii) the weighted average number of KFN's common shares outstanding in such quarter. The incentive fee is paid quarterly in arrears and is not subject to any hurdle or clawback provisions. The management agreement with KFN was renewed on January 1, 2013 and will automatically be renewed for successive one-year terms following December 31, 2013 unless the agreement is terminated in accordance with its terms.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Hedge Fund Structures

        Incentive fees earned on the performance of certain hedge fund structures are recognized based on fund performance, subject to the achievement of minimum return levels, and/or high water marks, in accordance with the respective terms set out in each fund's governing agreements. Incentive fee rates generally range from 5% to 20%. KKR does not record performance-based incentive fees until the end of each fund's measurement period (which is generally one year) when the performance-based incentive fees become fixed and determinable.

Investment Income

        Investment income consists primarily of the net impact of: (i) realized and unrealized gains and losses on investments which are recorded in net gains (losses) from investment activities, (ii) dividends, (iii) interest income, (iv) interest expense and (v) foreign exchange gains and losses relating to mark-to-market activity on foreign exchange forward contracts, foreign currency options and foreign denominated debt which are recorded in net gains (losses) from investment activities. Unrealized gains or losses result from changes in fair value of investments during the period and are included in Net Gains (Losses) from Investment Activities. Upon disposition of an investment, previously recognized unrealized gains or losses are reversed and a realized gain or loss is recognized.

Dividend Income

        Dividend income is recognized by KKR on the ex-dividend date, or in the absence of a formal declaration, on the date it is received. For the years ended December 31, 2012, 2011 and 2010, the majority of dividends were earned by the consolidated KKR Funds.

Interest Income

        Interest income is recognized as earned. For the years ended December 31, 2012, 2011 and 2010, the majority of interest income was earned by the consolidated KKR Funds.

Interest Expense

        Interest expense is incurred from credit facilities entered into by KKR, debt issued by KKR, and debt outstanding at the KKR funds entered into with the objective of enhancing returns or managing cash flow, which are not direct obligations of the general partners of the KKR funds or management companies. In addition to these interest costs, KKR capitalizes debt financing costs incurred in connection with new debt arrangements. Such costs are amortized into interest expense using either the interest method or the straight-line method, as appropriate.

Compensation and Benefits

        Compensation and Benefits expense includes cash compensation consisting of salaries, bonuses, and benefits, as well as equity based compensation consisting of charges associated with the vesting of equity-based awards and carry pool allocations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

        All KKR principals and other employees of certain consolidated entities receive a base salary that is paid by KKR or its consolidated entities, and is accounted for as Compensation and Benefits expense in the consolidated statements of operations. These employees are also eligible to receive discretionary cash bonuses based on performance, overall profitability and other matters. While cash bonuses paid to most employees are borne by KKR and certain consolidated entities and result in customary compensation and benefits expense, cash bonuses that are paid to certain of KKR's principals are currently borne by KKR Holdings. These bonuses are funded with distributions that KKR Holdings receives on KKR Group Partnership Units held by KKR Holdings but are not then passed on to holders of unvested units of KKR Holdings. Because KKR principals are not entitled to receive distributions on units that are unvested, any amounts allocated to principals in excess of a principal's vested equity interests are reflected as employee compensation and benefits expense. These compensation charges are recorded based on the unvested portion of quarterly earnings distributions received by KKR Holdings at the time of the distribution.

        Further disclosure regarding equity based compensation is presented in Note 10 "Equity Based Compensation."

Profit Sharing Plan

        KKR provides certain profit sharing programs for KKR employees and other eligible personnel. In particular, KKR provides a 401(k) plan (the "Plan") for eligible employees in the United States. For certain professionals who are participants in the Plan, KKR may, in its discretion, contribute an amount after the end of the Plan year. For the years ended December 31, 2012, 2011 and 2010, KKR incurred expenses of $4.6 million, $4.3 million and $3.1 million, respectively, in connection with the Plan.

Carry Pool Allocation

        With respect to KKR's active and future funds and co-investment vehicles that provide for carried interest, KKR will allocate to its principals and other professionals a portion of the carried interest earned in relation to these funds as part of its carry pool. KKR currently allocates approximately 40% of the carry it earns from these funds and vehicles to its carry pool. These amounts are accounted for as compensatory profit-sharing arrangements in Accounts Payable, Accrued Expenses and Other Liabilities within the statement of financial condition in conjunction with the related carried interest income and recorded as compensation expense for KKR employees and general, administrative and other expense for certain non-employee consultants and service providers in the consolidated statements of operations. See Note 12 "Segment Reporting" for the amount of carry pool allocation expense recognized for the years ended December 31, 2012, 2011 and 2010.

Carried Interest

        Carried interest entitles the general partner of a fund to a greater allocable share of the fund's earnings from investments relative to the capital contributed by the general partner and correspondingly reduce noncontrolling interests' attributable share of those earnings. Amounts earned pursuant to carried interest are included as investment income (loss) in Net Gains (Losses) from Investment Activities in the consolidated statements of operations and are earned by the general partner of those funds to the extent that cumulative investment returns are positive and where

applicable, preferred return thresholds have been met. If these investment returns decrease or turn negative in subsequent periods, recognized carried interest will be reversed and reflected as investment losses in Net Gains (Losses) from Investment Activities in the consolidated statements of operations. Carried interest is recognized based on the contractual formula set forth in the agreements governing the fund as if the fund was terminated at the reporting date with the then estimated fair values of the investments realized. Due to the extended durations of KKR's private equity funds and other investment vehicles, KKR believes that this approach results in income recognition that best reflects the periodic performance of KKR in the management of those funds. For funds that are consolidated, all investment income (loss), including the portion of a funds' investment income (loss) that is allocable to KKR's carried interest, is included in investment income (loss) on the consolidated statements of operations. The carried interest that KKR retains in net income (loss) attributable to KKR & Co. L.P. is reflected as an adjustment to net income (loss) attributable to noncontrolling interests. See Note 12 "Segment Reporting" for the amount of carried interest income earned or reversed for years ended December 31, 2012, 2011 and 2010.

        The agreements governing KKR's private equity funds generally include a "clawback" or, in certain instances, a "net loss sharing" provision that, if triggered, may give rise to a contingent obligation that may require the general partner to return or contribute amounts to the fund for distribution to fund investors at the end of the life of the fund. See Note 15 "Commitments and Contingencies".

General, Administrative and Other

        General, administrative and other expense consists primarily of professional fees paid to legal advisors, accountants, advisors and consultants, insurance costs, travel and related expenses, communications and information services, depreciation and amortization charges and costs incurred in connection with pursuing potential investments that do not result in completed transactions.

Foreign Currency

        Foreign currency denominated assets and liabilities are primarily held at management and capital markets companies located outside the United States. Foreign currency denominated assets and liabilities are translated using the exchange rates prevailing at the end of each reporting period. Results of foreign operations are translated at the weighted average exchange rate for each reporting period. Translation adjustments are included as a component of accumulated other comprehensive income until realized. Foreign currency gains or losses resulting from transactions outside of the functional currency of a consolidated entity are recorded as incurred in general, administrative and other expense in the consolidated statements of operations.

Net Income (Loss) Attributable to KKR & Co. L.P. Per Common Unit

        Basic Net Income (Loss) Attributable to KKR & Co. L.P. per common unit is calculated by dividing Net Income (Loss) attributable to KKR & Co. L.P. by the weighted average number of common units outstanding during the period.

The KKR Holdings units are excluded from the diluted calculation since the exchange of these units would proportionally increase KKR & Co. L.P.'s interests in the KKR Group Partnerships and would have an anti-dilutive effect on earnings per common unit as a result of certain tax benefits KKR & Co. L.P. is assumed to receive upon the exchange.

        Diluted Net Income (Loss) Attributable to KKR & Co. L.P. per common unit include unvested equity awards that have been granted under the KKR & Co. L.P. 2010 Equity Incentive Plan ("Equity Incentive Plan") since these equity awards dilute KKR and KKR Holdings pro rata in accordance with their respective percentage interests in the KKR Group Partnerships.

        Further disclosure regarding Net Income (Loss) Attributable to KKR & Co. L.P. per common unit is presented in Note 6 "Net Income (Loss) Attributable to KKR & Co. L.P. Per Common Unit."

Income Taxes

        The consolidated entities of KKR are generally treated as partnerships or disregarded entities for U.S. and non-U.S. tax purposes. However, certain consolidated subsidiaries are treated as corporations for U.S. and non-U.S tax purposes and are therefore subject to U.S. federal, state and/or local income taxes at the entity-level. In addition, certain consolidated entities which are treated as partnerships for U.S. tax purposes are subject to the New York City Unincorporated Business Tax or other local taxes.

        Income taxes are accounted for using the asset and liability method of accounting. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax basis, using tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred assets and liabilities of a change in tax rates is recognized in income in the period when the change is enacted. Deferred tax assets, which are recorded in Other Assets within the statement of financial condition, are reduced by a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized.

        For a particular tax-paying component of an entity and within a particular tax jurisdiction, deferred tax assets and liabilities are offset and presented as a single amount within Other Assets or Accounts Payable, Accrued and Other Liabilities, as applicable, in the accompanying statements of financial position.

        KKR analyzes its tax filing positions in all of the U.S. federal, state, local and foreign tax jurisdictions where it is required to file income tax returns, as well as for all open tax years in these jurisdictions. If, based on this analysis, KKR determines that uncertainties in tax positions exist, a reserve is established. KKR recognizes accrued interest and penalties related to uncertain tax positions within the provision for income taxes in the consolidated statements of operations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

        KKR records uncertain tax positions on the basis of a two-step process: (a) determination is made whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position and (b) those tax positions that meet the more-likely-than-not threshold are recognized as the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

Tax Receivable Agreement

        KKR and certain intermediate holding companies that are taxable corporations for U.S. federal, state and local income tax purposes, may be required to acquire KKR Group Partnership Units from time to time pursuant to the exchange agreement with KKR Holdings. KKR Management Holdings L.P. made an election under Section 754 of the Internal Revenue Code that will remain in effect for each taxable year in which an exchange of KKR Group Partnership Units for common units occurs, which may result in an increase in KKR's intermediate holding companies' share of the tax basis of the assets of the KKR Group Partnerships at the time of an exchange of KKR Group Partnership Units. Certain of these exchanges are expected to result in an increase in KKR's intermediate holding companies' share of the tax basis of the tangible and intangible assets of the KKR Group Partnerships, primarily attributable to a portion of the goodwill inherent in KKR's business that would not otherwise have been available. This increase in tax basis may increase depreciation and amortization deductions for tax purposes and therefore reduce the amount of income tax KKR's intermediate holding companies would otherwise be required to pay in the future. This increase in tax basis may also decrease gain (or increase loss) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets.

        KKR has entered into a tax receivable agreement with KKR Holdings, which requires KKR's intermediate holding companies to pay to KKR Holdings, or to executives who have exchanged KKR Holdings units for KKR common units (as transferees of KKR Group Partnership Units), 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax that the intermediate holding companies realize as a result of the increase in tax basis described above, as well as 85% of the amount of any such savings the intermediate holding companies realize as a result of increases in tax basis that arise due to future payments under the agreement. A termination of the agreement or a change of control could give rise to similar payments based on tax savings that KKR would be deemed to realize in connection with such events. In the event that other of KKR's current or future subsidiaries become taxable as corporations and acquire KKR Group Partnership Units in the future, or if KKR becomes taxable as a corporation for U.S. federal income tax purposes, KKR expects that each will become subject to a tax receivable agreement with substantially similar terms.

        These payment obligations are obligations of KKR's intermediate holding companies and not the KKR Group Partnerships. As such, cash payments received by common unitholders may vary from those received by current and former holders of KKR Group Partnership Units held by KKR Holdings and KKR's principals to the extent payments are made to those parties under the tax receivable agreement. Payments made under the tax receivable agreement are required to be made within 90 days of the filing of the tax returns of KKR's intermediate holding companies which may result in a timing difference between the tax savings received by KKR's intermediate holdings companies and the cash payments made to the selling holders of KKR Group Partnership Units.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

        As of December 31, 2012, approximately $2.9 million of cumulative cash payments have been made under the tax receivable agreement. KKR expects its intermediate holding companies to benefit from the remaining 15% of cash savings, if any, in income tax that they realize. As of December 31, 2012, $0.5 million of cumulative income tax savings have been realized.

Recently Issued Accounting Pronouncements

Fair Value Measurements

        In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2011-04, "Fair Value Measurement" ("ASU 2011-04"), which amended Accounting Standards Codification (ASC) 820 to clarify existing guidance and minimize differences between U.S. GAAP and International Financial Reporting Standards (IFRS). ASU 2011-04 requires entities to provide information about valuation techniques and unobservable inputs used in Level III fair value measurements and provide additional disclosures for classes of assets and liabilities disclosed at fair value. As a result of adopting ASU 2011-04, KKR has expanded its fair value disclosures. See section "Fair Value Measurements" above and Note 5 "Fair Value Measurements".

Presentation of Comprehensive Income

        In June 2011, the FASB issued Accounting Standards Update No. 2011-05, "Statement of Comprehensive Income" ("ASU 2011-05"), which requires entities to present net income and other comprehensive income in either a single continuous statement or in two separate, but consecutive, statements of net income and other comprehensive income. ASU 2011-05 was effective for KKR's fiscal year beginning January 1, 2012 and was applied retrospectively. The standard did not impact KKR's reported results of operations but did impact the financial statement presentation. KKR has adopted the presentation of total comprehensive income in two consecutive statements. See the consolidated statements of operations and consolidated statements of comprehensive income (loss).

Disclosures About Offsetting Assets and Liabilities

        In December 2011, the FASB issued ASU 2011-11, "Disclosures about Offsetting Assets and Liabilities" ("ASU 2011-11"), which requires entities to disclose information about offsetting and related arrangements of financial instruments and derivative instruments. In February 2013, the FASB issued ASU 2013-01, which clarifies which instruments and transactions are subject to the offsetting disclosure requirements established by ASU 2011-11.

        The guidance is effective for KKR's fiscal year beginning January 1, 2013 and is to be applied retrospectively. The adoption of this guidance, which is related to disclosure only, is not expected to have a material impact on KKR's consolidated financial statements.

Disclosures About Reclassification Adjustments Out of Accumulated Other Comprehensive Income

        In February 2013, the FASB issued ASU 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("AOCI")," which requires entities to disclose additional information about reclassification adjustments, including (i) changes in AOCI balances by component and (ii) significant items reclassified out of AOCI. The guidance is effective for KKR's fiscal year

beginning January 1, 2013 and is to be applied prospectively. The adoption of this guidance is not expected to have a material impact on KKR's consolidated financial statements.

Goodwill Impairment Testing

        In July 2012, the FASB issued ASU 2012-02, "Intangibles—Goodwill and Other," which provides the option to perform a qualitative, rather than quantitative, assessment to determine whether it is more likely than not an indefinite-lived intangible asset is impaired. If the asset is considered impaired, an entity is required to perform the quantitative assessment under the existing guidance. The guidance is effective for KKR's fiscal year beginning January 1, 2013. The adoption of this guidance, which is intended to simplify the impairment testing, is not expected to have a material impact on KKR's financial statements.

3. NET GAINS (LOSSES) FROM INVESTMENT ACTIVITIES

        Net Gains (Losses) from Investment Activities in the consolidated statements of operations consist primarily of the realized and unrealized gains and losses on investments (including foreign exchange gains and losses attributable to foreign denominated investments and related activities) and other financial instruments, including those for which the fair value option has been elected. Unrealized gains or losses result from changes in the fair value of these investments and other financial instruments during a period. Upon disposition of an investment or financial instrument, previously recognized unrealized gains or losses are reversed and an offsetting realized gain or loss is recognized in the current period.

equity nor fixed income investments. These investments were valued using Level III valuation methodologies that are generally the same as those shown for private equity investments.

        The various unobservable inputs used to determine the Level III valuations may have similar or diverging impacts on valuation. Significant increases and decreases in these inputs in isolation and interrelationships between those inputs could result in significantly higher or lower fair value measurements as noted in the table above.

6. NET INCOME (LOSS) ATTRIBUTABLE TO KKR & CO. L.P. PER COMMON UNIT

        For the years ended December 31, 2012, 2011 and 2010, basic and diluted Net Income (Loss) attributable to KKR & Co. L.P. per common unit were calculated as follows:

        For the years ended December 31, 2012, 2011 and 2010, KKR Holdings units have been excluded from the calculation of diluted Net Income (Loss) attributable to KKR & Co. L.P. per common unit since the exchange of these units would proportionally increase KKR & Co. L.P.'s interests in the KKR Group Partnerships and would have an anti-dilutive effect on earnings per common unit as a result of certain tax benefits KKR & Co. L.P. is assumed to receive upon the exchange.

        Diluted Net Income (Loss) attributable to KKR & Co. L.P. per common unit include unvested equity awards that have been granted under the KKR & Co. L.P. 2010 Equity Incentive Plan since these equity awards dilute KKR and KKR Holdings pro rata in accordance with their respective percentage interests in the KKR Group Partnerships.

Investment Financing Arrangements

        Certain of KKR's investment vehicles have entered into financing arrangements with major financial institutions, generally in connection with specific investments with the objective of enhancing returns. These financing arrangements are generally not direct obligations of the general partners of KKR's investment vehicles or its management companies.

        As of December 31, 2011, $796.4 million of financing was outstanding that was structured through the use of total return swaps which effectively convert third party capital contributions into borrowings of KKR. During May 2012, KKR entered into an agreement for an early redemption of one such financing arrangement. The terms of the agreement included a full repayment of the financing at par, which amounted to $625.0 million. During October 2012, KKR repaid the principal and accrued interest on the remaining $171.4 million outstanding financing in connection with the maturity of the underlying investment. As of December 31, 2012, there are no borrowings outstanding for financing arrangements structured through the use of total return swaps.

8. DEBT OBLIGATIONS (Continued)

        As of December 31, 2011, $182.2 million of financing was outstanding that was structured through the use of a syndicated term and a revolving credit facility (the "Term Facility") that matures in August 2014. During November 2012, KKR repaid $101.3 million of the outstanding financing. The per annum rate of interest for each borrowing under the Term Facility was equal to the Bloomberg United States Dollar Interest Rate Swap Ask Rate plus 1.75% at the time of each borrowing under the Term Facility through March 11, 2010. On March 11, 2010, the Term Facility was amended and the per annum rate of interest was the greater of the 5-year interest rate swap rate plus 1.75% or 4.65% for periods from March 12, 2010 to June 7, 2012. For the period June 8, 2012 through maturity the interest rate is equal to one year LIBOR plus 1.75%. The per annum interest rate at December 31, 2012 on the borrowings outstanding of $80.9 million was 2.82%. This financing arrangement is non-recourse to KKR beyond the specific assets pledged as collateral.

        In April 2011, one of KKR's private equity investment vehicles entered into a revolving credit facility with a major financial institution (the "Revolver Facility") with respect to a specific private equity investment. The Revolver Facility provides for up to $50.1 million of financing and matures on the first anniversary of the agreement. Upon the occurrence of certain events, including an event based on the value of the collateral and events of default, KKR may be required to provide additional collateral. KKR has the option to extend the agreement for an additional two years provided the value of the investment meets certain defined financial ratios. On April 5, 2012, an agreement was made to extend the maturity of the Revolver Facility to April 4, 2014. In addition, KKR may request to increase the commitment to the Revolver Facility up to $75.1 million, subject to lender approval and provided the value of the investment meets certain defined financial ratios. The per annum rate of interest for each borrowing under the Revolver Facility is equal to the Hong Kong interbank market rate plus 3.75%. The interest rate at December 31, 2012 on the borrowings outstanding was 4.30%. As of December 31, 2012 and 2011, $40.9 million and $40.8 million, respectively, of borrowings were outstanding under the Revolver Facility. This financing arrangement is non-recourse to KKR beyond the specific assets pledged as collateral.

        During May 2011, a KKR investment vehicle entered into a $200.0 million non-recourse multi-currency three-year revolving credit agreement that bears interest at LIBOR plus 2.75% (the "Mezzanine Investment Credit Agreement"). The Mezzanine Investment Credit Agreement is expected to be used to manage timing differences between capital calls from limited partners in the investment vehicle and funding of investment opportunities and to borrow in foreign currencies for purposes of hedging the foreign currency risk of non-U.S. dollar investments. On June 18, 2012, an agreement was made to extend the maturity of the Mezzanine Investment Credit Agreement to May 15, 2015. During the year ended December 31, 2012, $202.9 million was drawn down and $114.1 million was repaid. As of December 31, 2012 and 2011, $143.7 million and $47.1 million, respectively, of borrowings were outstanding under the Mezzanine Investment Credit Agreement. As of December 31, 2012, the interest rate on borrowings outstanding under the Mezzanine Investment Credit Agreement was 2.90%. This financing arrangement is non-recourse to KKR beyond the specific assets and capital commitments pledged as collateral.

        In November 2011, a KKR investment vehicle entered into a $200.0 million five-year borrowing base revolving credit facility (the "2011 Lending Partners Credit Agreement"). KKR has the option to extend the credit facility for up to two additional years. In addition, KKR may request to increase the

commitment to the credit facility up to $400.0 million when the ratio of the loan commitments to committed equity capital is 1.50:1. On April 2, 2012, KKR increased the commitment to the credit facility to $400.0 million. The per annum rate of interest for each borrowing under the 2011 Lending Partners Credit Agreement ranges from LIBOR plus 1.75% for broadly syndicated loans and LIBOR plus 2.75% for all other loans until November 15, 2016 and thereafter, LIBOR plus 4.00% per annum for all loans. During the year ended December 31, 2012, $200.2 million was drawn down and $30.2 million was repaid. As of December 31, 2012, $170.0 million of borrowings were outstanding under the 2011 Lending Partners Credit Agreement. As of December 31, 2011 there were no borrowings outstanding under the 2011 Lending Partners Credit Agreement. As of December 31, 2012, the interest rate on borrowings outstanding under the 2011 Lending Partners Credit Agreement was 2.97%. In January 2013, this KKR investment vehicle entered into a $150.0 million 5-year borrowing base revolving credit facility (the "2013 Lending Partners Credit Agreement"). KKR has the option to extend the credit facility for one additional year. The per annum rate of interest for borrowings under the 2013 Lending Partners Credit Agreement shall be the applicable spread plus libor rate as stated in the credit facility agreement. This financing arrangement is non-recourse to KKR beyond the specific assets pledged as collateral.

        In December 2011, a KKR investment vehicle entered into a $66.5 million (€50.0 million) one-year borrowing base revolving credit facility that bears interest at LIBOR plus 1.75% (the "Investment Credit Agreement"). In December 2012, KKR renewed the revolving credit facility for one year. The Investment Credit Agreement is expected to be used to manage timing differences between capital calls and the funding of investment opportunities. During the year ended December 31, 2012, $69.7 million was drawn down and $26.6 million was repaid. As of December 31, 2012, $39.5 million of borrowings were outstanding under the Investment Credit Agreement. There were no borrowings outstanding as of December 31, 2011. As of December 31, 2012, the interest rate on borrowings outstanding under the Investment Credit Agreement was 1.97%. This financing arrangement is non-recourse to KKR beyond the specific assets and capital commitments pledged as collateral.

        In January 2012, a KKR investment vehicle entered into a $200.0 million three-year borrowing base revolving credit facility (the "KKR Debt Investors II Investment Credit Agreement"). As of December 31, 2012, $150 million of borrowings were outstanding under the KKR Debt Investors II Investment Credit Agreement. During the year ended December 31, 2012, $150.0 million was drawn down and remains outstanding as of December 31, 2012. As of December 31, 2012, the interest rate on borrowings outstanding under the KKR Debt Investors II Investment Credit Agreement was 3.50%. This financing arrangement is non-recourse to KKR beyond the specific assets pledged as collateral.

        On September 29, 2010, KKR Group Finance Co. LLC, a subsidiary of KKR Management Holdings Corp., issued $500 million aggregate principal amount of 6.375% Senior Notes (the "2020 Senior Notes"), which were issued at a price of 99.584%. The 2020 Senior Notes are unsecured and unsubordinated obligations of KKR Group Finance Co. LLC and will mature on September 29, 2020, unless earlier redeemed or repurchased. The 2020 Senior Notes are fully and unconditionally guaranteed, jointly and severally, by KKR & Co. L.P. and the KKR Group Partnerships.

        The 2020 Senior Notes bear interest at a rate of 6.375% per annum, accruing from September 29, 2010. Interest is payable semi-annually in arrears on March 29 and September 29 of each year, commencing on March 29, 2011. Interest expense on the 2020 Senior Notes totaled $31.9 million for the years ended December 31, 2012 and 2011, respectively, and $8.1 million for the year ended December 31, 2010. As of December 31, 2012, the fair value of the 2020 Senior Notes was $579.2 million.

        The indenture, as supplemented by a first supplemental indenture, relating to the 2020 Senior Notes includes covenants, including limitations on KKR Group Finance Co. LLC and the guarantors' ability to, subject to exceptions, incur indebtedness secured by liens on voting stock or profit participating equity interests of their subsidiaries or merge, consolidate or sell, transfer or lease assets.

In the case of specified events of bankruptcy, insolvency, receivership or reorganization, the principal amount of the 2020 Senior Notes and any accrued and unpaid interest on the 2020 Senior Notes automatically becomes due and payable. All or a portion of the 2020 Senior Notes may be redeemed at the issuer's option in whole or in part, at any time, and from time to time, prior to their stated maturity, at the make-whole redemption price set forth in the 2020 Senior Notes. If a change of control repurchase event occurs, the 2020 Senior Notes are subject to repurchase by the issuer at a repurchase price in cash equal to 101% of the aggregate principal amount of the 2020 Senior Notes repurchased plus any accrued and unpaid interest on the 2020 Senior Notes repurchased to, but not including, the date of repurchase.

        On February 1, 2013, KKR Group Finance Co.

        The 2043 Senior Notes bear interest at a rate of 5.50% per annum, accruing from February 1, 2013. Interest is payable semi-annually in arrears on February 1 and August 1 of each year, commencing on August 1, 2013.

        The indenture, as supplemented by a first supplemental indenture, relating to the 2043 Senior Notes includes covenants, including limitations on KKR Group Finance Co. II LLC and the guarantors' ability to, subject to exceptions, incur indebtedness secured by liens on voting stock or profit participating equity interests of their subsidiaries or merge, consolidate or sell, transfer or lease assets. The indenture, as supplemented, also provides for events of default and further provides that the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding 2043 Senior Notes may declare the 2043 Senior Notes immediately due and payable upon the occurrence and during the continuance of any event of default after expiration of any applicable grace period. In the case of specified events of bankruptcy, insolvency, receivership or reorganization, the principal

All or a portion of the 2043 Senior Notes may be redeemed at the issuer's option in whole or in part, at any time, and from time to time, prior to their stated maturity, at the make-whole redemption price set forth in the 2043 Senior Notes. If a change of control repurchase event occurs, the 2043 Senior Notes are subject to repurchase by the issuer at a repurchase price in cash equal to 101% of the aggregate principal amount of the 2043 Senior Notes repurchased plus any accrued and unpaid interest on the 2043 Senior Notes repurchased to, but not including, the date of repurchase.

KKR Revolving Credit Agreements

Corporate Credit Agreement

        On February 26, 2008, Kohlberg Kravis Roberts & Co. L.P. entered into a credit agreement with a major financial institution (the "Corporate Credit Agreement"). The Corporate Credit Agreement originally provided for revolving borrowings of up to $1.0 billion, with a $50.0 million sublimit for swing-line notes and a $25.0 million sublimit for letters of credit.

        On February 22, 2011, the parties amended the terms of the Corporate Credit Agreement such that effective March 1, 2011, availability for borrowings under the credit facility was reduced from $1.0 billion to $700.0 million and the maturity was extended to March 1, 2016. In addition, the KKR Group Partnerships became co-borrowers of the facility, and KKR & Co. L.P. and the issuer of the 2020 Senior Notes became guarantors of the amended and restated Corporate Credit Agreement, together with certain general partners of KKR's private equity funds.

        On June 3, 2011, the Corporate Credit Agreement was amended to admit a new lender, subject to the same terms and conditions, to provide a commitment of $50.0 million. This commitment has increased the availability for borrowings under the credit facility to $750.0 million. As of December 31, 2012 and 2011, no borrowings were outstanding under the Corporate Credit Agreement. For the year ended December 31, 2012, no amounts were drawn under the credit facility.

        On June 22, 2012, KKR requested the issuance of a letter of credit in the amount of $14.5 million under the Corporate Credit Agreement in connection with a fee-generating transaction. The beneficiary of this letter of credit is an unaffiliated third party. The letter of credit was issued on July 2, 2012 and was initially set to expire on July 3, 2013. On August 20, 2012, the letter of credit in connection with this fee-generating transaction was increased to $20.0 million and the expiration date was extended to August 1, 2013. A $5.0 million sublimit for letters of credit remains available under the Corporate Credit Agreement.

KCM Credit Agreement

        On February 27, 2008, KKR Capital Markets entered into a revolving credit agreement with a major financial institution (the "KCM Credit Agreement") for use in KKR's capital markets business. The KCM Credit Agreement, as amended, provides for revolving borrowings of up to $500 million with a $500 million sublimit for letters of credit. On March 30, 2012, an agreement was made to extend the maturity of the KCM Credit Agreement from February 27, 2013 to March 30, 2017. In addition to extending the term, certain other terms of the KCM Credit Agreement were renegotiated including a

reduction of the cost of funding on amounts drawn and a reduced commitment fee. Borrowings under this facility may only be used for KKR's capital markets business. As of December 31, 2012 and 2011, no borrowings were outstanding under the KCM Credit Agreement. For the year ended December 31, 2012, no amounts were drawn under the credit facility.

        KKR files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, KKR is subject to examination by federal and certain state, local and foreign tax regulators. As of December 31, 2012, the federal, state and local tax returns of KKR and its predecessor entities for the years 2009 through 2011 are open under normal statute of limitations and are therefore subject to examination.

        At December 31, 2012, 2011and 2010, KKR's unrecognized tax benefits, excluding related interest and penalties, were:

        If the above tax benefits were recognized it would reduce the annual effective income tax rate. KKR believes that there will not be a significant increase or decrease to the tax positions within 12 months of the reporting date.

        The unrecognized tax benefits are recorded in Accounts Payable, Accrued Expenses and Other Liabilities. KKR recognizes interest and penalties accrued related to unrecognized tax positions in income taxes. For the years ended December 31, 2012, 2011 and 2010, interest and penalties included in KKR's tax provision were immaterial.

KKR Holdings Equity Awards—Principal Awards

        KKR principals and certain non-employee consultants and service providers received grants of KKR Holdings units which are exchangeable for KKR Group Partnership Units. These units are subject to minimum retained ownership requirements and in certain cases, transfer restrictions, and allow for their exchange into common units of KKR & Co. L.P. on a one-for-one basis. As of December 31, 2012 and 2011, KKR Holdings owned approximately 63.1%, or 432,553,276 and 66.8%, or 456,214,235, respectively, of the outstanding KKR Group Partnership Units.

        Except for any units that vested on the date of grant, units are subject to service based vesting, generally over a three to five year period from the date of grant. The transfer restriction period will generally last for a minimum of (i) one year with respect to one-half of the interests vesting on any vesting date and (ii) two years with respect to the other one-half of the interests vesting on such vesting date. While providing services to KKR, these individuals will also be subject to minimum retained ownership rules requiring them to continuously hold at least 25% of their vested interests. Upon separation from KKR, certain individuals will be subject to the terms of a non-compete agreement that may require the forfeiture of certain vested and unvested units should the terms of the non-compete agreement be violated. Holders of KKR Group Partnership Units held through KKR Holdings are not entitled to participate in distributions made on KKR Group Partnership Units until such units are vested.

        Because KKR Holdings is a partnership, all of the 432,553,276 KKR Holdings units have been legally allocated, but the allocation of 29,438,740 of these units has not been communicated to each respective principal. The units that have not been communicated are subject to performance based vesting conditions, which include profitability and other similar criteria. These criteria are not sufficiently specific to constitute performance conditions for accounting purposes, and the achievement, or lack thereof, will be determined based upon the exercise of judgment by the general partner of KKR Holdings. Each principal will ultimately receive between zero and 100% of the units initially allocated. The allocation of these units has not yet been communicated to the award recipients as this was management's decision on how to best incentivize its principals. It is anticipated that additional service-based vesting conditions will be imposed at the time the allocation is initially communicated to the respective principals. KKR applied the guidance of Accounting Standards Code ("ASC") 718 and concluded that these KKR Holdings units do not yet meet the criteria for recognition of compensation cost because neither the grant date nor the service inception date has occurred. In reaching a conclusion that the service inception date has not occurred, KKR considered (a) the fact that the vesting conditions are not sufficiently specific to constitute performance conditions for accounting purposes, (b) the significant judgment that can be exercised by the general partner of KKR Holdings in determining whether the vesting conditions are ultimately achieved, and (c) the absence of communication to the principals of any information related to the number of units they were initially allocated. The allocation of these units will be communicated to the award recipients when the performance-based vesting conditions have been met, and currently there is no plan as to when the communication will occur. The determination as to whether the award recipients have satisfied the performance-based vesting conditions is made by the general partner of KKR Holdings, and is based on multiple factors primarily related to the award recipients' individual performance.

10. EQUITY BASED COMPENSATION (Continued)

        The fair value of KKR Holdings unit grants is based on the closing price of KKR & Co. L.P. common units on the date of grant. KKR determined this to be the best evidence of fair value as a KKR & Co. L.P. common unit is traded in an active market and has an observable market price. Additionally, a KKR Holdings unit is an instrument with terms and conditions similar to those of a KKR & Co. L.P. common unit. Specifically, units in both KKR Holdings and KKR & Co. L.P. represent ownership interests in KKR Group Partnership Units and, subject to any vesting, minimum retained ownership requirements and transfer restrictions referenced above, each KKR Holdings unit is exchangeable into a KKR Group Partnership Unit and then into a KKR & Co. L.P. common unit on a one-for-one basis.

        Units granted to principals give rise to equity-based payment charges in the consolidated statements of operations based on the grant-date fair value of the award. For units vesting on the grant date, expense is recognized on the date of grant based on the fair value of a KKR & Co. L.P. common unit on the grant date multiplied by the number of vested units. Equity-based payment expense on unvested units is calculated based on the fair value of a KKR & Co. L.P. common unit at the time of grant, discounted for the lack of participation rights in the expected distributions on unvested units which currently ranges from 7% to 52%, multiplied by the number of unvested units on the grant date. The grant date fair value of a KKR & Co. L.P. unit reflects a discount for lack of distribution participation rights because equity awards are not entitled to receive distributions while unvested. The discount range was based on management's estimates of future distributions that unvested equity awards will not be entitled to receive between the grant date and the vesting date. Therefore, units that vest in the earlier periods have a lower discount as compared to units that vest in later periods, which have a higher discount. The discount range will generally increase when the level of expected annual distributions increases relative to the grant date fair value of a KKR & Co. L.P. common unit. A decrease in expected annual distributions relative to the grant date fair value of a KKR & Co. L.P. common unit would generally have the opposite effect.

        Units granted to certain non-employee consultants and service providers give rise to general, administrative and other charges in the consolidated statements of operations. For units vesting on the grant date, expense is recognized on the date of grant based on the fair value of a KKR & Co. L.P. common unit on the grant date multiplied by the number of vested units. General, administrative and other expense recognized on unvested units is calculated based on the fair value of a KKR & Co. L.P. common unit on each reporting date and subsequently adjusted for the actual fair value of the award at each vesting date. Accordingly, the measured value of these units will not be finalized until each vesting date.

        The calculation of equity-based payment expense and general administrative and other expense on unvested units assumes a forfeiture rate of up to 4% annually based upon expected turnover by class of principal, consultant, or service provider.

        As of December 31, 2012, there was approximately $146.4 million of estimated unrecognized equity-based payment and general administrative and other expense related to unvested awards. That cost is expected to be recognized over a weighted-average period of 0.8 years, using the graded attribution method, which treats each vesting portion as a separate award.

KKR Holdings Equity Awards—Restricted Equity Units

        Grants of restricted equity units based on KKR Group Partnership Units held by KKR Holdings were made to professionals, support staff, and other personnel. These grants will be funded by KKR Holdings and will not dilute KKR's interests in the KKR Group Partnerships. The vesting of these restricted equity units occur in installments, generally over a three to five year period from the date of grant. Units granted to professionals, support staff and other personnel are measured and recognized on a basis similar to KKR Holdings equity awards except that the fair value of a KKR & Co. L.P. common unit at the time of grant is not discounted for the lack of distribution participation rights since unvested units are entitled to distributions. The calculation assumes a forfeiture rate of up to 4% annually based upon expected turnover by class of professionals, support staff, and other personnel.

        As of December 31, 2012, there was approximately $3.8 million of estimated unrecognized expense related to unvested awards. That cost is expected to be recognized over a weighted average period of 0.9 years, using the graded attribution method, which treats each vesting portion as a separate award.

        A summary of the remaining vesting tranches of KKR Holdings' restricted equity awards granted to KKR professionals, support staff, and other personnel is presented below:

KKR & Co. L.P. 2010 Equity Incentive Plan

        Under the KKR & Co. L.P. 2010 Equity Incentive Plan, KKR is permitted to grant equity awards representing ownership interests in KKR & Co. L.P. common units. Vested awards under the Equity Incentive Plan dilute KKR & Co. L.P. common unitholders and KKR Holdings pro rata in accordance with their respective percentage interests in the KKR Group Partnerships.

        The total number of common units that may be issued under the Equity Incentive Plan is equivalent to 15% of the number of fully diluted common units outstanding, subject to annual adjustment. As of December 31, 2012, equity awards relating to 21,509,666 KKR & Co. L.P. common units have been granted under the Equity Incentive Plan and are subject to service based vesting, which vest generally over a three to five year period from the date of grant. In certain cases, these awards are subject to transfer restrictions and minimum retained ownership requirements. The transfer restriction period, if applicable, lasts for (i) one year with respect to one-half of the interests vesting on any vesting date and (ii) two years with respect to the other one-half of the interests vesting on such vesting date. While providing services to KKR, if applicable, certain of these individuals are also subject to

minimum retained ownership rules requiring them to continuously hold common unit equivalents equal to at least 15% of their cumulatively vested interests.

        Expense associated with the vesting of these awards is based on the closing price of the KKR & Co. L.P. common units on the date of grant, discounted for the lack of participation rights in the expected distributions on unvested units, which currently ranges from 7% to 52% multiplied by the number of unvested units on the grant date. The grant date fair value of a KKR & Co. L.P. unit reflects a discount for lack of distribution participation rights because equity awards are not entitled to receive distributions while unvested. The discount range was based on management's estimates of future distributions that unvested equity awards will not be entitled to receive between the grant date and the vesting date. Therefore, units that vest in the earlier periods have a lower discount as compared to units that vest in later periods, which have a higher discount. The discount range will generally increase when the level of expected annual distributions increases relative to the grant date fair value of a KKR & Co. L.P. common unit. A decrease in expected annual distributions relative to the grant date fair value of a KKR & Co. L.P. common unit would generally have the opposite effect. Expense is recognized on a straight line basis over the life of the award and assumes a forfeiture rate of up to 4% annually based upon expected turnover by class of recipient.

        As of December 31, 2012, there was approximately $126.5 million of estimated unrecognized expense related to unvested awards. That cost is expected to be recognized over a weighted average period of 1.5 years, using the straight line method.

        A summary of the status of awards granted under the Equity Incentive Plan from January 1, 2012 through December 31, 2012 is presented below:

        The weighted average remaining vesting period over which unvested awards are expected to vest is 1.9 years.

Discretionary Compensation

        All KKR principals and other employees of certain consolidated entities are eligible to receive discretionary cash bonuses. While cash bonuses paid to most employees are borne by KKR and certain consolidated entities and result in customary compensation and benefits expense, cash bonuses that are paid to certain of KKR's principals are currently borne by KKR Holdings. These bonuses are funded with distributions that KKR Holdings receives on KKR Group Partnership Units held by KKR Holdings but are not then passed on to holders of unvested units of KKR Holdings. Because KKR principals are not entitled to receive distributions on units that are unvested, any amounts allocated to principals in excess of a principal's vested equity interests are reflected as employee compensation and benefits expense. These compensation charges are recorded based on the unvested portion of quarterly earnings distributions received by KKR Holdings at the time of the distribution.

KFN

        KFN is a publicly traded specialty finance company whose limited liability company interests are listed on the NYSE under the symbol "KFN." KFN is managed by KKR but is not consolidated by KKR. KFN was organized in August 2004 and completed its initial public offering on June 24, 2005. As of December 31, 2012 and 2011, KFN had consolidated assets of $8.4 billion and $8.6 billion, respectively, and shareholders' equity of $1.8 billion and $1.7 billion, respectively. Shares of KFN held by KKR represented 0.1% of KFN's outstanding shares as of December 31, 2012. There were no outstanding shares of KFN held by KKR as of December 31, 2011. If KKR were to exercise all of its outstanding vested options, KKR's ownership interest in KFN would be 0.35% and 0.34% of KFN's outstanding shares as of December 31, 2012 and December 31, 2011, respectively.

Discretionary Investments

        Certain of KKR's investment professionals, including its principals and other qualifying employees, are permitted to invest, and have invested, their own capital in side-by-side investments with KKR's investment vehicles. Side-by-side investments are made on the same terms and conditions as those acquired by the applicable investment vehicle, except that the side-by-side investments are not subject to management fees, incentive fees or a carried interest. The cash invested by these individuals aggregated $108.9 million, $227.8 million and $66.8 million for the years ended December 31, 2012, 2011 and 2010, respectively.

Aircraft and Other Services

        Certain of the Senior Principals own aircraft that KKR uses for business purposes in the ordinary course of its operations. These Senior Principals paid for the purchase of these aircraft with personal funds and bear all operating, personnel and maintenance costs associated with their operation. The hourly rates that KKR pays for the use of these aircraft are based on current market rates for chartering private aircraft of the same type. KKR incurred $4.6 million, $5.0 million and $5.2 million for the use of these aircraft for the years ended December 31, 2012, 2011 and 2010, respectively.

12. SEGMENT REPORTING

        KKR operates through three reportable business segments. These segments, which are differentiated primarily by their investment objectives and strategies, consist of the following:

Private Markets

        Through the Private Markets segment, KKR manages and sponsors a group of private equity funds and co-investment vehicles that invest capital for long-term appreciation, either through controlling ownership of a company or strategic minority positions. KKR also manages and sources investments in infrastructure, natural resources and real estate. These investment funds, vehicles and accounts are managed by Kohlberg Kravis Roberts & Co. L.P., an SEC registered investment adviser.

Public Markets

        Through the Public Markets segment, KKR manages KKR Financial Holdings LLC, or KFN, which is a specialty finance company, as well as a number of investment funds, structured finance vehicles and separately managed accounts that invest capital in (i) leveraged credit strategies, such as leveraged loans and high yield bonds, (ii) liquid long/short equity strategies, (iii) alternative credit strategies such as mezzanine investments, special situations investments and direct senior lending and (iv) hedge funds solutions. Many of these funds, vehicles and accounts, including three management investment companies registered under the 1940 Act, are managed by KKR Asset Management LLC, or KAM, an SEC registered investment adviser. KKR's hedge fund solutions strategies are managed by Prisma Capital Partners LP, an SEC registered investment adviser.

Capital Markets and Principal Activities

        The Capital Markets and Principal Activities segment combines KKR's principal assets with its global capital markets business. KKR's capital markets business supports the firm, its portfolio companies and select third parties by providing tailored capital markets advice and by developing and implementing both traditional and non-traditional capital solutions for investments and companies seeking financing. KKR's capital markets services include arranging debt and equity financing for transactions, placing and underwriting securities offerings, structuring new investment products and providing capital markets services. KKR's principal asset base primarily includes investments in its private equity funds, co-investments in certain portfolio companies of such private equity funds, general partner interests in various KKR-sponsored investment funds, and other principal assets.

Key Performance Measures

        The non-GAAP segment key performance measures that follow are used by management in making operating and resource deployment decisions as well as assessing the overall performance of

each of KKR's reportable business segments. The reportable segments for KKR's business are presented prior to giving effect to the allocation of income (loss) between KKR & Co. L.P. and KKR Holdings and as such represents the business in total. In addition, KKR's reportable segments are presented without giving effect to the consolidation of the funds that KKR manages.

FRE

        FRE is comprised of segment operating revenues less segment operating expenses and is used by management as an alternative measurement of the operating earnings of KKR and its business segments before investment income. The components of FRE on a segment basis differ from the equivalent GAAP amounts on a consolidated basis as a result of: (i) the inclusion of management fees earned from consolidated funds that were eliminated in consolidation; (ii) the exclusion of fees and expenses of certain consolidated entities; (iii) the exclusion of charges relating to the amortization of intangible assets; (iv) the exclusion of charges relating to carry pool allocations; (v) the exclusion of non-cash equity charges and other non-cash compensation charges borne by KKR Holdings or incurred under the Equity Incentive Plan; (vi) the exclusion of certain reimbursable expenses; and (vii) the exclusion of certain non-recurring items.

ENI

        ENI is a measure of profitability for KKR's reportable segments and is used by management as an alternative measurement of the operating and investment earnings of KKR and its business segments. ENI is comprised of: (i) FRE; plus (ii) segment investment income (loss), which is reduced for carry pool allocations and management fee refunds; less (iii) certain economic interests in KKR's segments held by third parties. ENI differs from net income (loss) on a GAAP basis as a result of: (i) the exclusion of the items referred to in FRE above; (ii) the exclusion of investment income (loss) relating to noncontrolling interests; and (iii) the exclusion of income taxes.

Book Value

        Book Value is a measure of the net assets of KKR's reportable segments and is used by management primarily in assessing the unrealized value of KKR's investment portfolio, including carried interest, as well as KKR's overall liquidity position. Book value differs from the equivalent GAAP amounts on a consolidated basis primarily as a result of the exclusion of ownership interests attributable to KKR Holdings L.P.

(1)

KKR's agreements with the limited partners of certain of its investment funds require KKR to share with these limited partners an agreed upon percentage of monitoring and transaction fees received from Portfolio Companies ("Fee Credits"). Limited partners receive Fee Credits only with respect to monitoring and transaction fees that are allocable to the fund's investment in the Portfolio Company

and not, for example, any fees allocable to capital invested through co-investment vehicles. Fee Credits are calculated after deducting certain fund-related expenses and generally amount to 80% of allocable monitoring and transaction fees after fund-related expenses are recovered, although the actual percentage may vary from fund to fund.

(2)

With respect to KKR's active and future investment funds and co-investment vehicles that provide for carried interest, KKR will allocate to its principals, other professionals and selected other individuals who work in these operations a portion of the carried interest earned in relation to these funds as part of its carry pool.

(3)

Certain of KKR's private equity funds require the management company to refund up to 20% of any cash management fees earned from limited partners in the event that the funds recognize a carried interest. At such time as the fund recognizes a carried interest in an amount sufficient to cover 20% of the cash management fees earned or a portion thereof, a liability to the fund's limited partners is recorded and revenue is reduced for the amount of the carried interest recognized, not to exceed 20% of the cash management fees earned. As of December 31, 2010, the amount subject to refund for which no liability was recorded was approximately $58.7 million as a result of certain funds not yet recognizing sufficient carried interests. The refunds to the limited partners are paid, and the liabilities relieved, at such time that the underlying investments are sold and the associated carried interests are realized. In the event that a fund's carried interest is not sufficient to cover any of the amount that represents 20% of the cash management fees earned, these fees would not be returned to the funds' limited partners, in accordance with the respective fund agreements.

Represents economic interests that will (i) allocate to a former principal an aggregate of 1% of profits and losses of KKR's management companies until a future date and (ii) allocate to a third party investor approximately 2% of the equity in KKR's capital markets business.

        The following table reconciles KKR's total reportable segments to the consolidated financial statements as of and for the year ended December 31, 2010:

(a)

The fees adjustment primarily represents (i) the elimination of management fees of $388,501 upon consolidation of the KKR Funds, (ii) Fee Credits of $57,043 upon consolidation of the KKR Funds and (iii) inclusion of reimbursable expenses of $32,310.

13. ACQUISITIONS

Acquisition of Prisma

        On October 1, 2012, KKR completed the acquisition of 100% of the equity interests of Prisma Capital Partners LP and its affiliates ("Prisma"). Prisma is a provider of customized hedge fund solutions mainly through the management of funds of hedge fund portfolios. The addition of Prisma provides KKR with a new funds of hedge fund strategy and a greater presence in the hedge funds space, from which KKR can create and offer more liquid products for KKR's fund investors.

        Initial consideration transferred was $200.0 million in cash, and KKR may also become obligated to make future additional payments (referred to hereafter as "contingent consideration") to the sellers (certain of which are now employees of KKR) in years 2014 and 2017 based on the Prisma business achieving certain performance metrics when measured in such years. KKR has the right in its sole discretion to pay a portion of the contingent consideration, if any, in KKR & Co. L.P. common units rather than in cash. Changes in the fair value of the contingent consideration subsequent to the acquisition date will be recognized within General, Administrative and Other in the consolidated statements of operations.

        The following is a summary of the estimated fair values of the assets acquired and liabilities assumed:

        As of the acquisition date, the fair value of the contingent consideration was estimated to be $71.3 million and has been recorded as a liability within Accounts Payable, Accrued Expenses and Other Liabilities on the consolidated statements of financial condition. The fair value of the contingent consideration was derived using Level III inputs. This amount was determined based on the present value of a range of undiscounted cash flows of $0 to $155.0 million in each of 2014 and 2017, using a discount rate ranging from 2.1% to 3.1%, after applying probability, risk-weighting, and other adjustments that KKR has determined to be applicable.

        The consolidated statement of operations for the year ended December 31, 2012 includes the financial results of Prisma since the date of acquisition, October 1, 2012, through December 31, 2012. During this period, Prisma's fees and net income (loss) attributable to KKR & Co. L.P. were $17.2 million and $1.1 million, respectively. This net income (loss) attributable to KKR & Co. L.P. reflects amortization of intangible assets and equity based compensation charges associated with Prisma since the date of the acquisition. Additionally, the portion of net income that is allocable to KKR reflects KKR's approximate 36.9% ownership interest in the KKR Group Partnerships after applicable corporate and local income taxes. On a segment basis, the financial results of Prisma are included within the Public Markets segment.

13. ACQUISITIONS (Continued)

        The information that follows provides supplemental information about pro forma fees and net income (loss) attributable to KKR and Co. L.P. as if the acquisition of Prisma had been consummated as of January 1, 2011. Such information is unaudited and is based on estimates and assumptions which KKR believes are reasonable. These results are not necessarily indicative of the consolidated statements of operations in future periods or the results that would have actually been realized had KKR and Prisma been a combined entity during 2012 and 2011. On a pro forma basis for the years ended December 31, 2012 and 2011, (i) fees would be estimated to be $612.8 million and $782.0 million, respectively, (ii) net income (loss) attributable to KKR & Co. L.P. would be estimated to be $563.1 million and $3.9 million, respectively, (iii) net income (loss) attributable to KKR & Co. L.P. per common unit—basic would be estimated to be $2.36 and $0.02, respectively, and (iv) net income (loss) attributable to KKR & Co. L.P. per common unit—diluted would be estimated to be $2.22 and $0.02, respectively.

        KKR incurred $3.7 million of acquisition related costs which were expensed as incurred and are reflected within General, Administrative and Other Expense on the consolidated statement of operations.

14. GOODWILL AND INTANGIBLE ASSETS

Goodwill

        Goodwill from the acquisition of Prisma represents the excess of acquisition cost over the fair value of net tangible and intangible assets acquired and is primarily attributed to synergies expected to arise after the acquisition. The carrying value of goodwill was $89.0 million as of December 31, 2012 and is recorded within Other Assets on the consolidated statement of financial condition. This goodwill has been allocated entirely to the Public Markets Segment. As of December 31, 2012, the fair value of KKR's operating segments substantially exceeded their respective carrying values. All of the goodwill is currently expected to be deductible for tax purposes. See Note 7 "Other Assets and Accounts Payable, Accrued Expenses and Other Liabilities."

Intangible Assets

        Intangible Assets, Net consists of the following:

14. GOODWILL AND INTANGIBLE ASSETS (Continued)

        Changes in Intangible Assets, Net consists of the following:

        Amortization expense relating to intangible assets held at December 31, 2012 is expected to be $20.0 million for each of the years ending December 31, 2013 through 2016 and $19.4 million for the year ended December 31, 2017. The intangible assets as of December 31, 2012 are expected to amortize over a weighted-average period of 11.0 years.

15. COMMITMENTS AND CONTINGENCIES

Debt Covenants

        Borrowings of KKR contain various debt covenants. These covenants do not, in management's opinion, materially restrict KKR's investment or financing strategies. KKR is in compliance with its debt covenants in all material respects.

Investment Commitments

        As of December 31, 2012, KKR had unfunded commitments consisting of (i) $677.9 million to its active private equity and other investment vehicles, (ii) $125.0 million to KKR Asian Fund II L.P. for which the investment period has not yet commenced, subject to adjustment, and (iii) $94.2 million in connection with commitments by KKR's capital markets business related to credit facilities of Portfolio Companies and other companies. Whether these amounts are actually funded, in whole or in part depends on the terms of such commitments, including the satisfaction or waiver of any conditions to funding.

Non-cancelable Operating Leases

        KKR's non-cancelable operating leases consist primarily of leases of office space around the world. There are no material rent holidays, contingent rent, rent concessions or leasehold improvement incentives associated with any of these property leases. In addition to base rentals, certain lease agreements are subject to escalation provisions and rent expense is recognized on a straight-line basis over the term of the lease agreement.

15. COMMITMENTS AND CONTINGENCIES (Continued)

        As of December 31, 2012, the approximate aggregate minimum future lease payments, net of sublease income, required on the operating leases are as follows:

Contingent Repayment Guarantees

        The instruments governing KKR's private equity funds generally include a "clawback" provision that, if triggered, may give rise to a contingent obligation that may require the general partners to return amounts to the fund for distribution to the limited partners at the end of the life of the fund. Under a "clawback" provision, upon the liquidation of a fund, the general partner is required to return, on an after-tax basis, previously distributed carry to the extent that, due to the diminished performance of later investments, the aggregate amount of carry distributions received by the general partner during the term of the fund exceed the amount to which the general partner was ultimately entitled.

        Carried interest is recognized in the statement of operations based on the contractual conditions set forth in the agreements governing the fund as if the fund were terminated and liquidated at the reporting date and the fund's investments were realized at the then estimated fair values. Amounts earned pursuant to carried interest are earned by the general partner of those funds to the extent that cumulative investment returns are positive and where applicable, preferred return thresholds have been met. If these investment amounts earned decrease or turn negative in subsequent periods, recognized carried interest will be reversed and to the extent that the aggregate amount of carry distributions received by the general partner during the term of the fund exceed the amount to which the general partner was ultimately entitled, a clawback obligation would be recorded. For funds that are consolidated, this clawback obligation, if any, is reflected as an increase in noncontrolling interests in the consolidated statements of financial condition. For funds that are not consolidated, this clawback obligation, if any, is reflected as a reduction of KKR's investment balance as this is where carried interest is initially recorded.

        Certain KKR principals who received carried interest distributions prior to October 1, 2009 with respect to the private equity funds had personally guaranteed, on a several basis and subject to a cap, the contingent obligations of the general partners of the private equity funds to repay amounts to fund limited partners pursuant to the general partners' clawback obligations. KKR principals remain responsible for any clawback obligations relating to carry distributions received prior to October 1, 2009, up to a maximum of $223.6 million. As of December 31, 2012, no amounts are due with respect to the clawback obligation required to be funded by KKR principals who do not hold direct controlling economic interests in the KKR Group Partnerships. Carry distributions arising subsequent to October 1, 2009 may give rise to clawback obligations that will be allocated generally to carry pool

participants and KKR. KKR will indemnify its principals for any personal guarantees that they have provided with respect to such amounts.

        As of December 31, 2012, the amount of carried interest that is subject to this clawback provision was $1,095.4 million, assuming that all applicable private equity funds were liquidated at no value. Had the investments in such funds been liquidated at their December 31, 2012 fair values, there would have been no clawback obligation.

        The instruments governing certain of KKR's private equity funds may also include a "net loss sharing provision," that, if triggered, may give rise to a contingent obligation that may require the general partners to contribute capital to the fund, to fund 20% of the net losses on investments. In connection with the "net loss sharing provisions," certain of KKR's private equity vehicles allocate a greater share of their investment losses to KKR relative to the amounts contributed by KKR to those vehicles. In these vehicles, such losses would be required to be paid by KKR to the limited partners in those vehicles in the event of a liquidation of the fund regardless of whether any carried interest had previously been distributed. Based on the fair market values as of December 31, 2012, there would have been no net loss sharing obligation. If the vehicles were liquidated at zero value, the net loss sharing obligation would have been approximately $616.7 million as of December 31, 2012.

Indemnifications

        In the normal course of business, KKR enters into contracts that contain a variety of representations and warranties that provide general indemnifications. In addition, KKR has provided certain indemnities relating to environmental matters and has provided nonrecourse carve-out guarantees for fraud, willful misconduct and other customary wrongful acts, each in connection with the financing of certain real estate investments that KKR has made. KKR's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against KKR that have not yet occurred. However, based on experience, KKR expects the risk of material loss to be low.

Litigation

        From time to time, KKR is involved in various legal proceedings, lawsuits and claims incidental to the conduct of KKR's business. KKR's business is also subject to extensive regulation, which may result in regulatory proceedings against it.

        In August 1999, KKR and certain of its current and former personnel as well as the investment partnerships which made an investment were named as defendants in an action brought in the Circuit Court of Jefferson County, Alabama, or the Alabama State Court, alleging breach of fiduciary duty and conspiracy in connection with the acquisition of Bruno's, Inc. ("Bruno's"), one of KKR's former portfolio companies, in 1995. The action was removed to the U.S. Bankruptcy Court for the Northern District of Alabama. In April 2000, the complaint in this action was amended to further allege that KKR and others violated state law by fraudulently misrepresenting the financial condition of Bruno's in an August 1995 subordinated notes offering relating to the acquisition and in Bruno's subsequent periodic financial disclosures. In January 2001, the action was transferred to the U.S. District Court for the Northern District of Alabama. In 2009, the action was remanded to the Alabama State Court and subsequently consolidated for pretrial purposes with a similar action brought against the underwriters

of the August 1995 subordinated notes offering, which was pending before the Alabama State Court. The plaintiffs are seeking compensatory and punitive damages, in an unspecified amount to be proven at trial, for losses they allegedly suffered in connection with their purchase of the subordinated notes. In September 2009, KKR and the other named defendants moved to dismiss the action. In April 2010, the Alabama State Court granted in part and denied in part the motion to dismiss. In August 2011, the Alabama Supreme Court denied KKR's petition seeking permission to appeal certain rulings made by the Alabama State Court when denying in part the motion to dismiss. In October 2011, the plaintiffs' investment adviser filed an amended motion to dismiss a third-party complaint filed by KKR and other defendants asserting a contribution claim against the plaintiffs' investment adviser, which was granted, without prejudice, in October 2012. In December 2011, KKR filed a petition for a writ of certiorari in the United States Supreme Court seeking permission to appeal the Alabama Supreme Court's denial of KKR's petition. In January 2012, the Alabama State Court granted a motion to sever the action from the related action against the underwriters of the subordinated notes. In May 2012, the United States Supreme Court denied KKR's petition for a writ of certiorari. Discovery is ongoing, and trial is scheduled to begin in May 2013.

        On May 23, 2011, KKR, certain KKR affiliates and the board of directors of Primedia Inc. (a former KKR portfolio company whose directors at that time included certain KKR personnel) were named as defendants, along with others, in two shareholder class action complaints filed in the Court of Chancery of the State of Delaware challenging the sale of Primedia in a merger transaction that was completed on July 13, 2011. These actions allege, among other things, that Primedia board members, KKR, and certain KKR affiliates, breached their fiduciary duties by entering into the merger agreement at an unfair price and failing to disclose all material information about the merger. Plaintiffs also allege that the merger price was unfair in light of the value of certain shareholder derivative claims, which were dismissed on August 8, 2011, based on a stipulation by the parties that the derivative plaintiffs and any other former Primedia shareholders lost standing to prosecute the derivative claims on behalf of Primedia when the Primedia merger was completed. The dismissed shareholder derivative claims included allegations concerning open market purchases of certain shares of Primedia's preferred stock by KKR affiliates in 2002 and allegations concerning Primedia's redemption of certain shares of Primedia's preferred stock in 2004 and 2005, some of which were owned by KKR affiliates. With respect to the pending shareholder class actions challenging the Primedia merger, on June 7, 2011, the Court of Chancery denied a motion to preliminarily enjoin the merger. On July 18, 2011, the Court of Chancery consolidated the two pending shareholder class actions and appointed lead counsel for plaintiffs. On October 7, 2011, defendants moved to dismiss the operative complaint in the consolidated shareholder class action. The operative complaint seeks, in relevant part, unspecified monetary damages and rescission of the merger. On December 2, 2011, plaintiffs filed a consolidated amended complaint, which similarly alleges that the Primedia board members, KKR, and certain KKR affiliates breached their respective fiduciary duties by entering into the merger agreement at an unfair price in light of the value of the dismissed shareholder derivative claims. That amended complaint seeks an unspecified amount of monetary damages. On January 31, 2012, defendants moved to dismiss the amended complaint. The motion to dismiss the amended complaint is pending before the Court of Chancery.

        Additionally, in May 2011, two shareholder class actions challenging the Primedia merger were filed in Georgia state courts, asserting similar allegations and seeking similar relief as initially sought by

the Delaware shareholder class actions above. Both Georgia actions have been stayed in favor of the Delaware action.

        In December 2007, KKR, along with 15 other private equity firms and investment banks, were named as defendants in a purported class action complaint filed in the United States District Court for the District of Massachusetts by shareholders in certain public companies acquired by private equity firms since 2003. In August 2008, KKR, along with 16 other private equity firms and investment banks, were named as defendants in a purported consolidated amended class action complaint. The suit alleges that from mid-2003 defendants have violated antitrust laws by allegedly conspiring to rig bids, restrict the supply of private equity financing, fix the prices for target companies at artificially low levels, and divide up an alleged market for private equity services for leveraged buyouts. The amended complaint seeks injunctive relief on behalf of all persons who sold securities to any of the defendants in leveraged buyout transactions and specifically challenges nine transactions. The first stage of discovery concluded on or about April 15, 2010. On August 18, 2010, the court granted plaintiffs' motion to proceed to a second stage of discovery in part and denied it in part. Specifically, the court granted a second stage of discovery as to eight additional transactions but denied a second stage of discovery as to any transactions beyond the additional eight specified transactions. On October 7, 2010, the plaintiffs filed under seal a fourth amended complaint that includes new factual allegations concerning the additional eight transactions and the original nine transactions. The fourth amended complaint also includes eight purported sub-classes of plaintiffs seeking unspecified monetary damages and/or restitution with respect to eight of the original nine challenged transactions and new separate claims against two of the original nine challenged transactions. On January 13, 2011, the court granted a motion filed by KKR and certain other defendants to dismiss all claims alleged by a putative damages sub-class in connection with the acquisition of PanAmSat Corp. and separate claims for relief related to the PanAmSat transaction. The second phase of discovery permitted by the court is completed. On July 11, 2011, plaintiffs filed a motion seeking leave to file a proposed fifth amended complaint that seeks to challenge ten additional transactions in addition to the transactions identified in the previous complaints. Defendants opposed plaintiffs' motion. On September 7, 2011, the court granted plaintiffs' motion in part and denied it in part. Specifically, the court granted a third stage of limited discovery as to the ten additional transactions identified in plaintiffs' proposed fifth amended complaint but denied plaintiffs' motion seeking leave to file a proposed fifth amended complaint. On June 14, 2012, following the completion of the third phase of discovery, plaintiffs filed a fifth amended complaint which, like their proposed fifth amended complaint, seeks to challenge ten additional transactions in addition to the transactions identified in the previous complaints. On June 22, 2012, defendants filed a motion to dismiss certain claims asserted in the fifth amended complaint. On July 18, 2012, the court granted in part and denied in part defendants' motion to dismiss, dismissing certain previously released claims against certain defendants. On July 23, 2012, defendants, including KKR, filed motions for summary judgment, which is pending decision before the United States District Court.

        On March 4, 2011, KKR received a request from the SEC for information relating to the acquisition of Del Monte Foods Company by private equity funds affiliated with KKR and two other private equity firms, which was announced on November 25, 2010 and completed on March 8, 2011. On May 20, 2011 the SEC issued a subpoena to KKR seeking substantially the same documents and information as the March 4, 2011 request for information. On December 16, 2011, the SEC issued another subpoena to KKR seeking documents and information regarding the period prior to the

announcement of the acquisition of Del Monte Foods Company. KKR is cooperating with the SEC's investigations.

        In September 2006 and March 2009, KKR received requests for certain documents and other information from the Antitrust Division of the U.S. Department of Justice ("DOJ") in connection with the DOJ's investigation of private equity firms to determine whether they have engaged in conduct prohibited by United States antitrust laws. KKR is cooperating with the DOJ's investigation.

        In January 2011, KKR received a request from the SEC for information regarding KKR's fund investors and clients that the SEC defines as sovereign wealth funds and certain services provided by KKR. On December 19, 2011, the SEC issued a subpoena to KKR seeking additional documents and information involving certain sovereign wealth funds specified by the SEC, and on December 6, 2012 and February 15, 2013, the SEC requested some additional documents and information pursuant to such subpoena regarding the specified sovereign wealth funds. KKR is cooperating with the SEC's investigation.

        In July 2012, KKR received a subpoena from the New York State Attorney General's Office seeking information and documents concerning the waiver or deferral of management fees with respect to funds where KKR or its affiliate serves or served as such a fund's general partner. KKR is cooperating with this investigation.

        Moreover, in the ordinary course of business KKR is subject to governmental and regulatory examinations or investigations and also is and can be both the defendant and the plaintiff in numerous actions with respect to acquisitions, bankruptcy, insolvency and other types of proceedings. Such lawsuits may involve claims that adversely affect the value of certain investments owned by KKR's funds.

        KKR establishes an accrued liability for litigation, regulatory and other matters only when those matters present loss contingencies that are both probable and reasonably estimable. In such cases, there may be an exposure to loss in excess of any amounts accrued. No loss contingency is recorded for matters where such losses are either not probable or reasonably estimable (or both) at the time of determination. Such matters are subject to many uncertainties, including among others (i) the proceedings are in early stages; (ii) damages sought are unspecified, unsupportable, unexplained or uncertain; (iii) discovery has not been started or is incomplete; (iv) there is uncertainty as to the outcome of pending appeals or motions; (v) there are significant factual issues to be resolved; or (vi) there are novel legal issues or unsettled legal theories to be presented or a large number of parties. Consequently, management is unable to estimate a range of potential loss, if any, related to these matters. For one or more of the matters described above for which a loss is both probable and reasonably estimable, we have estimated the aggregate amount of losses attributable to KKR to be approximately $32.5 million. We believe such losses should be, in whole or in part, subject to insurance and/or indemnity, which we believe will reduce any ultimate loss. This estimate is based upon information available as of February 21, 2013 and is subject to significant judgment and a variety of assumptions and uncertainties. Actual outcomes may vary significantly from this estimate.

        It is not possible to predict the ultimate outcome of all pending investigations and legal proceedings, and some of the matters discussed above seek potentially large and/or indeterminate amounts. As of such date, based on information known by management, management has not

concluded that the final resolutions of the matters above will have a material effect upon the consolidated financial statements. However, given the potentially large and/or indeterminate amounts sought in certain of these matters and the inherent unpredictability of investigations and litigations, it is possible that an adverse outcome in certain matters could, from time to time, have a material effect on our financial results in any particular period.

16. REGULATORY CAPITAL REQUIREMENTS

        KKR has a registered broker-dealer which is subject to the minimum net capital requirements of the SEC and the Financial Industry Regulatory Authority ("FINRA"). Additionally, KKR has an entity based in London which is subject to the capital requirements of the U.K. Financial Services Authority, another entity based in Hong Kong which is subject to the capital requirements of the Hong Kong Securities and Futures Ordinance, an entity based in Japan subject to the Financial Services Authority of Japan, and two entities based in Mumbai which are subject to capital requirements of the Reserve Bank of India ("RBI") and Securities and Exchange Board of India ("SEBI"). All of these broker dealer entities have continuously operated in excess of their respective minimum regulatory capital requirements.

        The regulatory capital requirements referred to above may restrict KKR's ability to withdraw capital from its registered broker-dealer entities. At December 31, 2012, approximately $75.1 million of cash at KKR's registered broker-dealer entities may be restricted as to the payment of cash dividends and advances to KKR.

ITEM 9    CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

        None.

ITEM 9A    CONTROLS AND PROCEDURES

        Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Our management, with the participation of our Co-Chief Executive Officers and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d- 15(e) under the Exchange Act) as of the end of the period covered by this report. Based on such evaluation, our Co-Chief Executive Officers and Chief Financial Officer have concluded that, as of the end of such period, our disclosure controls and procedures are at the reasonable assurance level: (i) effective in recording, processing, summarizing, and reporting information on a timely basis that we are required to disclose in the reports that we file or submit under the Exchange Act; and (ii) effective in ensuring that information that we are required to disclose in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our Co-Chief Executive Officers and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. On October 1, 2012, we acquired Prisma Capital Partners LP and its affiliates (as discussed in Note 13 to the accompanying audited consolidated financial statements). The internal control over financial reporting of Prisma Capital Partners LP and its affiliates was excluded from the evaluation of the company's effectiveness of our disclosure controls and procedures as of December 31, 2012.

Management's Report on Internal Control Over Financial Reporting

        Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) is a process designed by, or under the supervision of, a company's principal executive and principal financial officers and effected by the board of directors, management and other personnel, to provide reasonable, but not absolute, assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

        Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company;

        Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

        Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2012. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework.

        Based on its assessment, our management believes that, as of December 31, 2012, our internal control over financial reporting is effective.

        On October 1, 2012, we acquired Prisma Capital Partners LP and its affiliates (as discussed in Note 13 to the accompanying audited consolidated financial statements). We are in the process of evaluating the internal controls of the acquired business. However, as permitted by related SEC Staff interpretive guidance for newly acquired businesses, we excluded the internal control over financial reporting of the acquired business from management's annual assessment of the effectiveness of our internal control over financial reporting as of December 31, 2012. In the aggregate, this business represented approximately 0.6% of our total consolidated assets and approximately 3.0% of our total consolidated fees as of and for the fiscal year ended December 31, 2012.

Changes in Internal Control Over Financial Reporting

        No changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act) occurred during the fourth quarter of 2012 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Independence and Composition of the Board of Directors

        Our Managing Partner's board of directors consists of eight directors, six of whom, Messrs. Grundfest, Hess, Rampl, Schoewe and Scully and Ms. Russo, are independent under NYSE rules relating to corporate governance matters and the independence standards described in our corporate governance guidelines. While we are exempt from NYSE rules relating to board independence, our Managing Partner intends to maintain a board of directors that consists of at least a majority of directors who are independent under NYSE rules relating to corporate governance matters. In addition, the board has considered transactions between KKR and the companies and organizations on whose boards our directors also serve.

Board Committees

        Our Managing Partner's board of directors has four standing committees: an audit committee, a conflicts committee, a nominating and corporate governance committee and an executive committee that operate pursuant to written charters as described below. Because we are a limited partnership, our Managing Partner's board is not required by NYSE rules to establish a compensation committee or a nominating and corporate governance committee or to meet other substantive NYSE corporate governance requirements. While the board has established a nominating and governance committee, we rely on available exemptions concerning the committee's composition and mandate.

Audit Committee

        The audit committee consists of Messrs. Grundfest (Chairman), Schoewe and Scully. The purpose of the audit committee is to assist the board of directors in overseeing and monitoring: (i) the quality and integrity of our financial statements; (ii) our compliance with legal and regulatory requirements; (iii) our independent registered public accounting firm's qualifications and independence; and (iv) the performance of our independent registered public accounting firm. The members of the audit committee meet the independence standards and financial literacy requirements for service on an audit committee of a board of directors pursuant to the Exchange Act and NYSE rules applicable to audit committees. The Managing Partner's board of directors has determined that each of Messrs. Grundfest, Schoewe and Scully is an "audit committee financial expert" within the meaning of Item 407(d)(5) of Regulation S-K. The audit committee has a charter which is available at the Investor Center section of our internet website at www.kkr.com.

Conflicts Committee

        The conflicts committee consists of Messrs. Grundfest, Hess, Rampl, Schoewe and Scully and Ms. Russo. The conflicts committee is responsible for reviewing specific matters that the board of directors believes may involve a conflict of interest and for enforcing our rights under any of the exchange agreement, the tax receivable agreement, the limited partnership agreement of any KKR Group Partnership or our limited partnership agreement, which we refer collectively to as the covered agreements, against KKR Holdings and certain of its subsidiaries and designees, a general partner or limited partner of KKR Holdings, or a person who holds a partnership or equity interest in the

235

Table of Contents

foregoing entities. The conflicts committee is also authorized to take any action pursuant to any authority or rights granted to such committee under any covered agreement or with respect to any amendment, supplement, modification or waiver to any such agreement that would purport to modify such authority or rights. In addition, the conflicts committee shall approve any amendment to any of the covered agreements that in the reasonable judgment of our Managing Partner's board of directors is or will result in a conflict of interest. The conflicts committee will determine if the resolution of any conflict of interest submitted to it is fair and reasonable to our partnership. Any matters approved by the conflicts committee will be conclusively deemed to be fair and reasonable to our partnership and not a breach of any duties that may be owed to our unitholders. In addition, the conflicts committee may review and approve any related person transactions, other than those that are approved pursuant to our related person policy, as described under "Certain Relationships and Related Transactions, and Director Independence—Statement of Policy Regarding Transactions with Related Persons," and may establish guidelines or rules to cover specific categories of transactions. The members of the conflicts committee meet the independence standards under our corporate governance guidelines as required for service on the conflicts committee in accordance with its charter.

Nominating and Corporate Governance Committee

        The nominating and corporate governance committee consists of Messrs. Kravis, Roberts and Scully. The nominating and corporate governance committee is responsible for identifying and recommending candidates for appointment to the board of directors and for assisting and advising the board of directors with respect to matters relating to the general operation of the board and corporate governance matters. Mr. Scully meets the independence standards under the rules of the NYSE as required for service on the nominating and corporate governance committee in accordance with its charter.

Executive Committee

        The executive committee consists of Messrs. Kravis and Roberts. The purpose of the executive committee is to act, when necessary, in place of our Managing Partner's full board of directors during periods in which the board is not in session. The executive committee is authorized and empowered to act as if it were the full board of directors in overseeing our business and affairs, except that it is not authorized or empowered to take actions that have been specifically delegated to other board committees or to take actions with respect to: (i) the declaration of distributions on our common units; (ii) a merger or consolidation of our partnership with or into another entity; (iii) a sale, lease or exchange of all or substantially all of our assets; (iv) a liquidation or dissolution of our partnership; (v) any action that must be submitted to a vote of our Managing Partner's members or our unitholders; or (vi) any action that may not be delegated to a board committee under our Managing Partner's limited liability company agreement or the Delaware Limited Liability Company Act.

Code of Business Conduct and Ethics

        We have a Code of Business Conduct and Ethics which applies to our principal executive officers, principal financial officer and principal accounting officer and is available on our internet website at www.kkr.com under the "Investor Center" section. In accordance with, and to the extent required by the rules and regulations of the Securities and Exchange Commission, we intend to disclose any amendment to or waiver of the Code of Business Conduct and Ethics on behalf of an executive officer or director either on our internet website or in a Current Report on Form 8-K filing.

Corporate Governance Guidelines

        Our Managing Partner's board of directors has a governance policy which addresses matters such as the board of directors' responsibilities and duties, the board of directors' composition and compensation and director independence. The governance guidelines are available on our internet website at www.kkr.com under the "Investor Center" section.

Communications to the Board of Directors

        The non-management members of our Managing Partner's board of directors meet regularly. At each meeting of the non-management members, the non-management directors choose a director to lead the meeting. All interested parties, including any employee or unitholder, may send communications to the non-management members of our Managing Partner's board of directors by writing to: the General Counsel, KKR & Co. L.P., 9 West 57^th Street, Suite 4200, New York, New York 10019.

Section 16(a) Beneficial Ownership Reporting Compliance

        Section 16(a) of the Exchange Act, requires the executive officers and directors of our general partner, and persons who own more than ten percent of a registered class of the Partnership's equity securities to file initial reports of ownership and reports of changes in ownership with the SEC and furnish the Partnership with copies of all Section 16(a) forms they file. To our knowledge, based solely on our review of the copies of such reports or written representations from such persons that they were not required to file a Form 5 to report previously unreported ownership or changes in ownership, we believe that, with respect to the fiscal year ended December 31, 2012, such persons complied with all such filing requirements, except that KKR Holdings had one late Form 4 filing relating to two transactions and Mr. Kravis and Mr. Roberts each had one late Form 4 filing relating to one transaction.

ITEM 11.    EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Compensation Philosophy

        Our compensation program has three primary objectives: (1) to attract, motivate and retain our employees, (2) to align their interests with those of our unitholders and fund investors, and (3) to reinforce our culture and values.

        Our employees.    Our business as an investment firm is dependent on the services of our principals (including our named executive officers) and other employees. Among other things, we depend on their ability to find, select and execute investments, manage and improve portfolio company operations, find and develop relationships with fund investors and other sources of capital, and provide other services, and we cannot compete without their continued employment with us. Therefore, it is important that our key employees are compensated in a manner that motivates them to excel and encourages them to remain with the firm.

        Alignment of interests.    Management equity ownership in the businesses in which we invest has been a guiding principle throughout our firm's history, and we apply that principle to ourselves: every employee of the firm is expected to have an equity interest in us. This equity ownership serves to align the interests of our employees with those of our unitholders. In addition, because we invest in and alongside our investment funds and have a carry pool from which we can allocate to our principals 40% of the carried interest that we generate through our business, we believe that our principals' interests are also aligned with those of our investors in the funds, vehicles and accounts that we manage, which in turn benefits our unitholders.

        Culture and values.    One of our most important values is our "one-firm" approach with shared responsibility and success, and we subscribe to a culture of meritocracy and fairness. Therefore, compensation is based on the performance of the firm as a whole and on an individual's contributions to the firm. For example, we do not compensate people based merely on an individual's accomplishments in relation to the profits and losses of his or her business unit. In addition, we

237

---

Table of Contents

conduct, at least annually, an evaluation process that seeks input from a wide range of persons on an employee's contribution to the firm, including his or her commitment to the firm's culture and values. We believe that using this kind of an evaluation process also promotes a measure of objectivity as a balance to a single manager's judgment.

        We refer to our two Co-Chief Executive Officers, our Chief Administrative Officer, our Chief Financial Officer and our General Counsel as our "named executive officers." We believe that the elements of compensation discussed below for our named executive officers serve these primary objectives. We, as a limited partnership with no annual meeting of unitholders, are not required to conduct say-on-pay or say-on-frequency votes as provided in the Dodd-Frank Act. However, we intend periodically to review the elements of our compensation, and we may make changes to the compensation structure relating to one or more named executive officers based on the outcome of such reviews from time to time.

KKR Holdings

        Each of our named executive officers holds interests in our business through KKR Holdings, which is the entity that indirectly owns all of the outstanding KKR Group Partnership Units that are not allocable to us.

        KKR Holdings units are, subject to certain restrictions, exchangeable for our common units, on a one-for-one basis, and generally cannot be sold to third parties for monetary value unless they are first exchanged for our common units. Because KKR Holdings units are exchangeable for our common units, we believe that our named executive officers' interests are aligned with those of our unitholders.

        KKR Holdings, from time to time, receives distributions that are made on KKR Group Partnership Units that are held by it. To the extent such distributions are received on KKR Group Partnership Units that underlie any KKR Holdings units that have satisfied their respective service-based vesting requirements, if any, at the time distributions are declared on the underlying KKR Group Partnership Units, such distributions will be allocated and further distributed to the named executive officers as and when received. To the extent that such distributions are made on KKR Group Partnership Units underlying any KKR Holdings units that have not satisfied initial vesting requirements at the time distributions are declared on the underlying KKR Group Partnership Units, such distributions may be allocated or otherwise applied in such amounts and in such manner as our Co-Chief Executive Officers, acting through the general partner of KKR Holdings, may determine. It is contemplated that such distributions with respect to unvested KKR Holdings units will generally be paid to our named executive officers and our other principals as annual bonus compensation from time to time.

        In 2012, our named executive officers received distributions on their vested KKR Holdings units, and because these distributions are not considered to be compensation, they have not been reported in the Summary Compensation Table.

Compensation Elements

Base Salary

        For 2012, each of our named executive officers was paid an annual salary of $300,000. We believe that the base salary of our named executive officers should typically not be the most significant component of total compensation. Our Co-Chief Executive Officers determined that this amount was a sufficient minimum base salary for our named executive officers and decided that it should be the same for all named executive officers. We are responsible for funding this base salary.

238

Table of Contents

Year-End Bonus Compensation

        Other than their salary and certain incidental benefits noted below under "Other Compensation," our Co-Chief Executive Officers did not receive any additional compensation in 2012. They have decided at this time not to receive any bonus or other amounts from us or from KKR Holdings in excess of distributions payable with respect to their KKR Holdings units. Instead, they have decided that year-end bonus payments from KKR Holdings should be made to our other principals in order to motivate and retain them for the benefit of the firm.

        In 2012, our Chief Administrative Officer, Chief Financial Officer and General Counsel were awarded additional year-end compensation as bonus payments that were determined by our Co-Chief Executive Officers. Our Co-Chief Executive Officers made their subjective determinations by assessing our overall performance and the contributions that our Chief Administrative Officer, Chief Financial Officer and General Counsel made to our development and success, as a firm, during the year. Certain factors that were considered when determining the size of the bonus payments for our Chief Administrative Officer, Chief Financial Officer and General Counsel include (i) their respective contributions and accomplishments in 2012 in terms of driving commercial results for the firm, leading and managing people, and living the firm's values; (ii) their respective performance and contributions relative to other senior principals in the firm, (iii) their respective performance and contributions in 2012 as compared to the prior year, and (iv) the overall financial performance of the firm in 2012 as compared to the prior year based on certain financial measures considered by management, including fee related earnings. More specifically, in assessing Mr. Fisher's contributions, they considered his service as the firm's Chief Administrative Officer, his role in overseeing the growth and operations of the firm, his leadership in the development of our real estate business and his leadership on the strategic direction of the firm generally. In assessing Mr. Janetschek's contributions, they considered his service as the Chief Financial Officer and his leadership and oversight of our finance, tax and accounting functions and his role with respect to strategic initiatives undertaken by the firm. Finally, in assessing Mr. Sorkin's contributions, they considered his leadership and oversight of our global legal and compliance functions and his role with respect to the strategic initiatives undertaken by the firm. Because the firm's fee related earnings declined in 2012 even though economic net income improved relative to the prior year, the size of the bonus payments was lower in 2012 as a result of the firm's financial performance. In making these determinations, our Co-Chief Executive Officers consulted with certain of our senior principals and, with respect to the determinations for our Chief Financial Officer and General Counsel, considered the recommendations of our Chief Administrative Officer. We believe that the discretion permitted to our Co-Chief Executive Officers permits them to award bonus compensation in an amount necessary to motivate and retain these named executive officers.

        Once the bonus amount is determined, the bonus amount is divided into cash compensation and, for our named executive officers, a recommendation to our Managing Partner's board of directors for an award of deferred equity bonus compensation. The amount of deferred equity bonus compensation for our principals is calculated using a graduated range of percentages applied to different incremental amounts of total salary and bonus compensation ranging from 5% to 50%.

        The cash bonus amounts paid to our Chief Administrative Officer, our Chief Financial Officer and our General Counsel for 2012 are reflected in the Bonus column of the 2012 Summary Compensation Table below. Although these cash bonus payments have been economically borne by KKR Holdings, we expect that, over time, we may be required to pay a portion, or eventually all, of these cash bonus payments as KKR Holdings becomes unable to reserve cash for bonus compensation as more KKR Holdings units vest.

        The portion of the bonus payment granted to our named executive officers (other than our Co-Chief Executive Officers, who received none) as 2012 deferred equity bonus compensation consists of grants of equity awards issued under the Equity Incentive Plan. These equity awards are restricted

239

equity units that may be settled for our common units on a one-for-one basis. See below under "Terms of Restricted Equity Units" for more information. We call these equity grants "deferred" equity bonus compensation, because our named executive officers' ability to monetize them into cash is deferred to the future when the vesting provisions (and any applicable transfer restrictions) discussed below lapse.

        The number of restricted equity units granted to our named executive officers (other than our Co-Chief Executive Officers, who received none) is determined by our Managing Partner's board of directors. As part of 2012 year-end bonus compensation, our Managing Partner's board of directors approved the following grants: 146,880 restricted equity units to our Chief Administrative Officer, 49,865 restricted equity units to our Chief Financial Officer, and 49,865 restricted equity units to our General Counsel. The number of restricted equity units was determined by dividing the dollar amount of deferred equity bonus compensation recommended by the Co-Chief Executive Officers to the board of directors, by the average closing price of our common units over the last five trading days in 2012. Because these grants were made after December 31, 2012, they do not appear in the tables below, but will appear in the tables for the year ended December 31, 2013.

        The restricted equity units that were granted as deferred equity bonus compensation grants in respect of fiscal 2012 year-end compensation are subject to a three-year service-based vesting condition (with the first vesting event occurring on April 1, 2014). These restricted equity units are not subject to additional transfer restrictions after vesting or any minimum retained ownership requirement. Vesting serves as an employment retention mechanism and thereby enhances the alignment of interests between our named executive officers who receive year-end compensation payments and the firm.

Carried Interest

        We allocate and distribute to a carry pool 40% of the carried interest that we earn, from which our principals are eligible to receive a carried interest allocation. Carry pool allocations are made first on a total dollar basis and then allocated on an investment by investment basis, and the percentage participation of the named executive officers in the carry pool varies by size of investment and in the aggregate. The carry pool is maintained and administered by KKR Associates Holdings L.P., which, similar to KKR Holdings, is not a subsidiary of ours. Allocations are determined by our Co-Chief Executive Officers acting through the general partner of KKR Associates Holdings L.P.

        Carried interest, if any, from the carry pool in respect of any particular investment is only paid in cash after all of the following are met: (i) a realization event has occurred (e.g., sale of a portfolio company, dividend, etc.); (ii) the vehicle has achieved positive overall investment returns since its inception, in excess of preferred returns where applicable; and (iii) with respect to investments with a fair value below cost, cost has been returned to fund investors in an amount sufficient to reduce remaining cost to the investments' fair value. To the extent any "clawback" obligation is triggered, carried interest previously distributed by the fund would have to be returned to such fund, thereby reducing the named executive officer's overall compensation for any such year. From time to time, a portion of certain carried interest payable may not be distributed to the recipient and would instead be held in escrow in order to enhance the recipient's ability to satisfy any future clawback obligation. Because the amount of carried interest payable is directly tied to the realized performance of the underlying investments, we believe this fosters a strong alignment of interests among the investors in those funds and the named executive officers, and thus benefits our unitholders. In addition, several of our competitors use participation in carried interest as an important compensation element, and we believe that we must do the same in order to attract and retain the most qualified personnel.

        Participation in our carry pool for our principals, including our named executive officers, is subject to service-based vesting with certain exceptions, including acceleration upon death or disability. Vesting schedules range from four-year vesting (with no vesting upon grant) for the most junior principals up to two-year vesting (and 50% vesting upon grant) for most senior principals. Vesting serves as an

240

Table of Contents

employment retention mechanism and enhances the alignment of interests between a participant in our carry pool and the firm as well as the limited partners in our investment funds. Due to their status as co-founders of our firm, our Co-Chief Executive Officers are typically completely vested in their carried interest allocations upon grant.

Other Compensation

        Our Co-Chief Executive Officers are reimbursed by us for the use of a car and driver, and we pay for the compensation of certain personnel who administer personal matters for them. We believe that these benefits are appropriate in light of the time that they spend on our business, the limited compensation paid by us for their services, and their unique status as co-founders of our firm.

        We allow our principals, including our named executive officers, to retain compensation that they may receive for serving as our designees on the boards of directors of KKR portfolio companies unless such compensation is required to be used to offset management fees pursuant to the terms of certain funds.

        Finally, certain named executive officers may receive equity grants from KKR Financial Holdings LLC (NYSE: KFN) for their services to that company. No equity grants from KFN were made to our named executive officers in 2012.

Minimum Retained Ownership

        While employed by us, unless waived in whole or in part, each of our named executive officers is required to hold at least 25% of the cumulative amount of KKR Holdings units that have satisfied the service-based vesting condition during the duration of his employment with the firm. In addition, unless waived in whole or in part, each of our named executive officers may be required, on a grant by grant basis, to hold common unit equivalents of 15% of the cumulative restricted equity units granted under the Equity Incentive Plan that have satisfied the service-based vesting condition during the duration of his employment with the firm.

Compensation and Risk

        Our compensation program includes elements that discourage excessive risk-taking and that align the compensation of our employees with the long-term performance of the firm. For example, other than certain equity that either immediately vested as part of the grants to all employees or our founders or that were made in exchange for the contribution of assets, in each case in connection with the consummation of the KPE Transaction in October 2009, a significant majority of the equity awards held by our principals are subject to a multi-year service vesting condition, one- and two-year transfer restriction periods, or a minimum retained ownership requirement. In addition, except in circumstances noted elsewhere in this report, the equity awards held by our other employees are also generally subject to a multi-year service vesting condition and may also be subject to post-vesting transfer restrictions and a minimum retained ownership requirement. Because our equity awards have multi-year vesting provisions, the actual amount of compensation realized by the recipient will be tied to the long-term performance of our common units. In addition, we only make cash payments of carried interest to our principals when profitable investments have been realized and after sufficient cash has been distributed to the investors in our funds. Moreover, the general partner of a fund is required to return carried interest distributions to the fund due to, for example, underperformance by the relevant fund subsequent to the payment of such carried interest. Accordingly, the principal would be subject to a "clawback," i.e., be required to return carried interest payments previously made to a principal, all of which further discourages excessive risk-taking by our personnel.

Summary Compensation Table

        The following table presents summary information concerning compensation that was paid for services rendered by our named executive officers during the fiscal years ended December 31, 2010, 2011 and 2012.

        In 2010, 2011 and 2012, our named executive officers received distributions based on their vested KKR Holdings units. Because these distributions are not considered to be compensation, these distributions are not reflected as compensation in the table below. There are certain contractual arrangements we entered into with KKR Holdings at the time of the KPE Transaction in October 2009 and thereafter, including a tax receivable agreement, that relate to payments to our named executive officers that are not compensatory and are described in "Certain Relationships and Related Transactions, and Director Independence."

        Carried interest distributions to our named executive officers in respect of the carry pool established by KKR Associates Holdings L.P. for the years ended December 31, 2010, 2011 and 2012 are reflected in the All Other Compensation column in the 2012 Summary Compensation Table below.

Grants of Plan-Based Awards in 2012

        The following table provides supplemental information relating to grants of equity awards provided in our Summary Compensation Table.

Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards

Terms of KKR Holdings Units

        The units that our named executive officers and other principals hold in KKR Holdings are subject to transfer restrictions and, except for interests held by our Co-Chief Executive Officers and certain interests that were vested when granted in connection with the consummation of the KPE Transaction in October 2009, subject to multi-year service-based vesting requirements. Due to their unique status as co-founders of our firm, our Co-Chief Executive Officers are completely vested in their ownership of KKR Holdings units.

        In general, unvested KKR Holdings units initially vest in equal installments over a multi-year period (which can range from three to five years) from the grant date, subject to the recipient's continued employment with us. Following this initial vesting (or the grant date if interests were vested upon grant), interests remain contingently vested while they are subject to certain transfer restrictions.

        KKR Holdings units that are subject to transfer restrictions, unless waived, may not be sold, exchanged or otherwise transferred for a specified period of time following the initial vesting date. The transfer restriction period typically lasts for (1) one year with respect to one-half of the units vesting on the initial vesting date and (2) two years with respect to the other one-half of the units vesting on such vesting date. Transfer restricted units become fully vested and may be exchanged into common units at

244

Table of Contents

the end of the transfer restriction period if the holder is not terminated for cause and has complied with the terms of his or her confidentiality and restrictive covenant agreement during the transfer restrictions period. See "Terms of Confidentiality and Restrictive Covenant Agreements" below.

        Because KKR Holdings is a partnership, all of the KKR Holdings units have been legally allocated, but the allocation of certain of these units had not been communicated to each respective principal as of December 31, 2012. The units whose allocation has not been communicated are subject to performance-based vesting conditions, which include, (i) whether the principal is in good standing and has adhered to our policies and rules, (ii) performance of assigned tasks and duties in an effective, efficient and diligent manner, (iii) contribution and commitment to the growth, development and profitability of KKR and our business, (iv) contribution and commitment to our management and general administration; (v) contribution and commitment to the culture, business principles, reputation and morale of KKR as a whole and the team or teams to which the principal has been assigned, and (vi) contribution and commitment to our recruiting, business development, public image and marketing efforts and the professional development of our personnel. These criteria are not sufficiently specific to constitute performance conditions for accounting purposes, and the achievement, or lack thereof, will be determined based upon the exercise of judgment by the general partner of KKR Holdings. Each principal will ultimately receive between zero and 100% of the units initially allocated. The allocation of these units has not yet been communicated to the award recipients as this was management's decision on how to best incentivize its principals. It is anticipated that additional service-based vesting conditions will be imposed at the time the allocation is initially communicated to the respective principals. We applied the guidance of ASC Topic 718 and concluded that these KKR Holdings units do not yet meet the criteria for recognition of compensation cost because neither the grant date nor the service inception date has occurred. In reaching a conclusion that the service inception date has not occurred, we considered (1) the fact that the vesting conditions are not sufficiently specific to constitute performance conditions for accounting purposes, (2) the significant judgment that can be exercised by the managing members in determining whether the vesting conditions are ultimately achieved, and (3) the absence of communication to the principals of any information related to the number of units they were initially allocated. The allocation of these units will be communicated to the award recipients when the performance-based vesting conditions have been met, and currently there is no plan as to when the communication will occur. The determination as to whether the award recipients have satisfied the performance-based vesting conditions is made by the general partner of KKR Holdings, and is based on multiple factors primarily related to the award recipients' individual performance.

        While employed by our firm, our principals, including our named executive officers, are also subject to minimum retained ownership rules that require them to continuously hold at least 25% of their cumulatively vested KKR Holdings units, unless waived.

        The transfer and vesting restrictions and minimum retained ownership rules applicable to KKR Holdings units may not be enforceable in all cases and can be waived, modified or amended by KKR Holdings at any time without our consent.

        The terms of the KKR Holdings units described above are distinct from equity awards issuable under our Equity Incentive Plan, which are described below.

Terms of Restricted Equity Units

        Restricted equity units are equity awards issuable under our Equity Incentive Plan, which after vesting, may be settled for our common units on a one-for-one basis.

        In general, restricted equity units are subject to a service-based vesting condition and vest in equal installments over a multi-year period (typically three years) from a specified date, subject to the recipient's continued employment with us. Following this service-based vesting, certain restricted equity

245

---

Table of Contents

unit grant agreements may also subject the common units delivered upon settlement of such restricted equity units to transfer restrictions and minimum retained ownership requirements.

        Common units delivered upon settlement of restricted equity units that are subject to transfer restrictions, unless waived, typically may not be sold, exchanged or otherwise transferred for a specified period of time following the vesting date. The transfer restriction period typically lasts for (1) one year with respect to one-half of the units vesting on the service-based vesting date and (2) two years with respect to the other one-half of the units vesting on such service-based vesting date. Transfer restricted common units become saleable at the end of the transfer restriction period if the holder has not been terminated for cause and has not breached in any significant or intentional manner, as determined by the Administrator, the terms of his or her confidentiality and restrictive covenants contained in the grant agreement during the transfer restriction period. See "Terms of Confidentiality and Restrictive Covenant Agreements" below.

        While employed by our firm, our principals, including our named executive officers, may also be subject to a minimum retained ownership requirement under the restricted equity unit grant agreement, which would obligate them to continuously hold common unit equivalents of 15% of their cumulatively vested restricted equity units, unless waived. From time to time, the transfer restrictions and minimum retained ownership requirements applicable to restricted equity units of certain principles, including our named executive officers, may be transferred to such principals' KKR Holdings units so that the total units of equity subject to transfer restrictions and minimum retained ownership requirements are expected to be the same, unless waived.

        For additional information about equity awards granted under our Equity Incentive Plan, please also see "KKR & Co. L.P. Equity Incentive Plan" below.

Terms of Confidentiality and Restrictive Covenant Agreements

        The confidentiality and restrictive covenant agreements with each of our named executive officers include prohibitions on them competing with us or soliciting certain fund investors or senior-level employees of our firm and specified subsidiaries and affiliates during a restricted period following their departure from the firm. These agreements also require personnel to protect and use the firm's confidential information only in accordance with confidentiality restrictions set forth in the agreement.

        The restricted periods for our Co-Chief Executive Officers expire on (1) for voluntary terminations or terminations with cause, the later of October 1, 2013 and two years from termination and (2) for terminations without cause, one year from termination. The restricted periods for our other named executive officers expire on (1) for voluntary terminations or terminations with cause, 18 months from termination, and (2) for terminations without cause, nine months from termination. These restricted periods are subject to reduction for any "garden leave" or "notice period" that an employee serves prior to termination of employment.

        Our named executive officers other than our Co-Chief Executive Officers have entered into these confidentiality and restrictive covenant agreements with us through their restricted equity unit grant agreements and separately also with KKR Holdings, which is entitled to waive, modify or amend them at any time without our consent. However, because our Co-Chief Executive Officers have not received any restricted equity units, their confidentiality and restrictive covenant agreements are solely with KKR Holdings. Because KKR Holdings is the party to these agreements and not us, we may not be able to enforce them, and these agreements might be waived, modified or amended at any time without our consent.

Potential Payments Upon Termination or Change in Control

        Upon termination of employment, vesting generally ceases for KKR Holdings units and restricted equity units that have not initially vested. In addition, transfer restricted vested KKR Holdings units and, if applicable, transfer restricted equity units (which term includes the transfer restricted common units that may be delivered upon settlement of such restricted equity units) remain subject to transfer restrictions for one- and two-year periods, except as described below.

        A principal who retires after the later of December 31, 2012 and the first date on which his or her age plus years of service to KKR equals 80 will continue to vest in his or her unvested KKR Holdings units and restricted equity units for an additional two years following retirement, subject to compliance, if applicable, with the requirement that the holder not violate the terms and conditions of his or her confidentiality and restrictive covenants during the period in which such KKR Holdings unit or, if applicable, restricted equity unit remains transfer restricted over one- and two-year periods. None of our named executive officers retired in the year ended December 31, 2012.

        Upon death or permanent disability, a holder of KKR Holdings units or restricted equity units becomes immediately vested in all unvested KKR Holdings units and restricted equity units, and the transfer restrictions, if any, immediately lapse.

In addition, carried interest allocations become immediately vested upon death or permanent disability.

Director Compensation

        We limit compensation for service on our Managing Partner's board of directors to the independent directors. Each independent director receives (1) an annual cash retainer of $75,000, (2) an additional annual cash retainer of $15,000 if such independent director is a member of the nominating and corporate governance committee, (3) an additional annual cash retainer of $25,000 if such independent director is a member of the audit committee and (4) an additional annual cash retainer of $15,000 if such independent director serves as the chairman of the audit committee. Cash retainers are pro rated if, during the calendar year, a director joins the board of directors of our Managing Partner or a director joins or resigns from a committee. In addition, on July 25, 2012, 10,000 restricted equity units were approved for grant to each independent director pursuant to our Equity Incentive Plan.

KKR & Co. L.P. Equity Incentive Plan

        Our Managing Partner has adopted the KKR & Co. L.P. 2010 Equity Incentive Plan, which is referred to as the Equity Incentive Plan.

Administration

        The board of directors of our Managing Partner administers the Equity Incentive Plan. However, the board of directors of our Managing Partner may delegate such authority, including to a committee or subcommittee of the board of directors. Under the terms of the Equity Incentive Plan, the board of directors of our Managing Partner, or the committee or subcommittee thereof to whom authority to administer the Equity Incentive Plan has been delegated, as the case may be, is referred to as the Administrator. The Administrator determines who will receive awards under the Equity Incentive Plan, as well as the form of the awards, the number of units underlying the awards and the terms and conditions of the awards, consistent with the terms of the Equity Incentive Plan. The Administrator has full authority to interpret and administer the Equity Incentive Plan and its determinations will be final and binding on all parties concerned. The Administrator may delegate the authority to grant awards and the day-to-day administration of the plan to any of our employees. Grants of equity awards to our named executive officers under our Equity Incentive Plan are made only by our Managing Partner's board of directors.

Common Units Subject to the Equity Incentive Plan

        The total number of our common units that may be issued under the Equity Incentive Plan as of the effective date of the plan was equivalent to 15% of the number of fully diluted common units outstanding as of such date; provided that beginning with the first fiscal year after the Equity Incentive Plan became effective and continuing with each subsequent fiscal year occurring thereafter, the aggregate number of common units covered by the plan will be increased, on the first day of each fiscal year of KKR & Co. L.P. occurring during the term of the plan, by a number of common units equal to the positive difference, if any, of (x) 15% of the aggregate number of common units outstanding (on a fully-diluted basis) on the last day of the immediately preceding fiscal year minus (y) the aggregate number of common units available for issuance under the plan as of the last day of such year, unless

250

Table of Contents

the Administrator should decide to increase the number of common units covered by the plan by a lesser amount on any such date.

Options and Unit Appreciation Rights

        The Administrator may award non-qualified unit options and unit appreciation rights under the Equity Incentive Plan. Options and unit appreciation rights granted under the Equity Incentive Plan will become vested and exercisable at such times and upon such terms and conditions as may be determined by the Administrator at the time of grant, but no option or unit appreciation right will be exercisable for a period of more than 10 years after it is granted. The exercise price per common unit will be determined by the Administrator, provided that options and unit appreciation rights granted to participants who are U.S. taxpayers (i) will not be granted with an exercise price less than 100% of the fair market value per underlying common unit on the date of grant and (ii) will not be granted unless the common unit on which it is granted constitutes equity of the participant's "service recipient" within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended. To the extent permitted by the Administrator, the exercise price of an option may be paid in cash or its equivalent, in common units having a fair market value equal to the aggregate exercise price and satisfying such other requirements as may be imposed by the Administrator, partly in cash and partly in common units or through net settlement in common units. As determined by the Administrator, unit appreciation rights may be settled in common units, cash or any combination thereof.

Other Equity-Based Awards

        The Administrator, in its sole discretion, may grant or sell common units, restricted common units, deferred restricted common units, phantom restricted common units, and any other awards that are valued in whole or in part by reference to, or are otherwise based on the fair market value of, the common units, including restricted equity units that may be granted from time to time, to our principals, including our named executive officers. Any of these other equity-based awards may be in such form, and dependent on such conditions, as the Administrator determines, including without limitation the right to receive, or vest with respect to, one or more common units (or the equivalent cash value of such units) upon the completion of a specified period of service, the occurrence of an event and/or the attainment of performance objectives. The Administrator may, in its discretion, determine whether other equity-based awards will be payable in cash, common units or other assets or a combination of cash, common units and other assets.

Compensation Committee Interlocks and Insider Participation

        Because we are a limited partnership, our Managing Partner's board of directors is not required by NYSE rules to establish a compensation committee. Our founders, Messrs. Kravis and Roberts, serve as Co-Chairmen of the board of directors of our Managing Partner. For a description of certain transactions between us and our founders, see "Certain Relationships and Related Transactions, and Director Independence."

Our Common Units

        The following table sets forth the beneficial ownership of our common units and KKR Group Partnership Units that are exchangeable for our common units by:

•

each person known to us to beneficially own more than 5% of any class of the outstanding voting securities of our partnership based on our review of filings with the SEC;



•

each of the directors, persons chosen to become a director and named executive officers of our Managing Partner; and



•

the directors, persons chosen to become a director and executive officers of our Managing Partner as a group.

        The numbers of common units and KKR Group Partnership Units outstanding and the percentage of beneficial ownership are based on 260,937,002 common units issued and outstanding and 424,979,965 KKR Group Partnership Units that are exchangeable for our common units as of February 21, 2013. Beneficial ownership is in each case determined in accordance with the rules of the SEC, and includes equity securities of which that person has the right to acquire beneficial ownership within 60 days of February 21, 2013. Under these rules, more than one person may be deemed a beneficial owner of the same securities and a person may be deemed a beneficial owner of securities as to which he has no economic interest.

Our Managing Partner

        Our Managing Partner's outstanding limited liability company interests consist of Class A shares, which are entitled to vote on the election and removal of directors and all other matters that have not been delegated to the board of directors or reserved for the vote of Class B members, and Class B shares, which are entitled to vote only with respect to any matter requiring the approval of holders of voting interests held directly or indirectly by us in the general partners of our non-U.S. funds. Notwithstanding the number of Class A shares held by the Class A members, under our Managing Partner's limited liability company agreement, Messrs. Kravis and Roberts are deemed to represent a majority of the Class A shares outstanding for purposes of voting on matters upon which holders of Class A shares are entitled to vote. Messrs. Kravis and Roberts may, in their discretion, designate one

or more holders of Class A shares to hold such voting power and exercise all of the rights and duties of Messrs. Kravis and Roberts under our Managing Partner's limited liability company agreement. While Messrs. Kravis and Roberts historically have acted with unanimity when managing our business, they have not entered into any agreement relating to the voting of their Class A shares. All of our Managing Partner's other Class A shares are held by our other senior principals. Our Managing Partner's Class B shares are divided equally among twelve principals, each of whom holds less than 10% of the voting power of the Class B shares. None of the shares in our Managing Partner provide these holders with economic interests in our business. See also "Risk Factors—Our limited partnership agreement contains provisions that reduce or eliminate duties (including fiduciary duties) of our limited partner and limit remedies available for unitholders for actions that might otherwise constitute a breach of duty. It will be difficult for unitholders to successfully challenge a resolution of a conflict of interest by our Managing Partner or by its conflicts committee." In addition, see "Risk Factors—We are a Delaware limited partnership, and there are provisions in our limited partnership agreement regarding exculpation and indemnification of our officers and directors that differ from the Delaware General Corporation Law (DGCL) in a manner that may be less protective of the interests of our common unitholders."

ITEM 13.    CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

        The following description is a summary of the material terms of the agreements described below, and does not contain all of the information that you may find useful. For additional information, you should read the copies of our investment agreement, our exchange agreement, our registration rights agreement, our tax receivable agreement and the partnership agreements of the KKR Group Partnerships, all of which have been filed as exhibits to this report.

The Investment Agreement

        On August 4, 2009, we entered into an investment agreement by and among us, certain of our affiliates, KPE and certain of its affiliates, as a condition to the KPE Transaction.

U.S. Listing

        The investment agreement provided that we and KPE each had the right to require that the other use its reasonable best efforts to cause KPE to contribute its units representing limited partner interests in Group Holdings to us in exchange for an equivalent number of our common units and, in connection therewith, our common units received by KPE to be listed and traded on the NYSE by delivering an election notice to the other party. On February 24, 2010, we delivered an election notice to KPE pursuant to the investment agreement, and we commenced trading on the NYSE on July 15, 2010 under the symbol "KKR".

Indemnification and Insurance

        The investment agreement provides that, for a period of six years after the closing of the NYSE listing on July 15, 2010, the KKR Group Partnerships will indemnify each present and former director and officer of the general partner of KPE and certain other persons serving in a similar role against all losses, liabilities, damages, judgments and fines incurred in connection with any suit, claim, action, proceeding, arbitration or investigation arising out of or related to actions taken by them in their capacity as directors or officers of the general partner of KPE or taken by them at the request of KPE or the general partner of KPE. In addition, the investment agreement also provides that the KKR Group Partnerships will indemnify us, KPE, each present and former director and officer of the general partner of KPE and certain other persons serving a similar role against all losses, liabilities, damages, judgments and fines to which any of them may become subject under the Securities Act, the Exchange Act, or other applicable law, statute, rule or regulation insofar as such losses, liabilities, damages, judgments and fines arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the registration statement relating to our common units to be issued to, and distributed by KPE or any other document issued by us, KPE or any of their respective affiliates in connection with, or otherwise relating to, our NYSE listing, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

        Pursuant to the investment agreement, we obtained directors' and officers' liability insurance for the benefit of the directors and officers (and former directors and officers) of the general partner of KPE which (i) is effective for a period from the date of the dissolution of KPE through and including the date that is six years after such date, (ii) covers claims arising out of or relating to any action, statement or omission of such directors and officers whether on or before the date of such dissolution (including the transactions contemplated by the investment agreement and the decision making process by the directors of the general partner of KPE in connection therewith) to the same extent as the directors and officers of our Managing Partner acting in their capacities as the directors and officers of

the general partner of KPE are insured with respect thereto, and (iii) contains a coverage limit of $100 million.

Exchange Agreement

        We have entered into an exchange agreement with KKR Holdings, the entity through which certain of our principals, including Messrs. Kravis, Roberts, Fisher, Janetschek and Sorkin, hold their KKR Group Partnership Units, pursuant to which KKR Holdings or certain transferees of its KKR Group Partnership Units may, on a quarterly basis (subject to the terms of the exchange agreement), exchange KKR Group Partnership Units held by them (together with corresponding special voting units) for our common units on a one-for-one basis, subject to customary conversion rate adjustments for splits, unit distributions and reclassifications. At the election of certain of our intermediate holding companies that are partners of the KKR Group Partnerships, the intermediate holding companies may settle exchanges of KKR Group Partnership Units with cash in an amount equal to the fair market value of the common units that would otherwise be deliverable in such exchanges. To the extent that KKR Group Partnership Units held by KKR Holdings or its transferees are exchanged for our common units, our interests in the KKR Group Partnerships will be correspondingly increased. Any common units received upon such exchange will be subject to any restrictions that were applicable to the exchanged KKR Group Partnership Units, including any applicable transfer restrictions. During the year ended December 31, 2012, 23,660,959 KKR Group Partnership Units were exchanged for our common units pursuant to this agreement.

        On November 2, 2010, the exchange agreement was amended and restated to provide certain rights to cancel exchanges or limit the number of units exchanged in a given quarter. The amendments also provided that certain exchanges will be with a new subsidiary, the result of which is that the income tax character of a small portion of income distributed to unitholders may differ from what it would have been absent the amendment. If additional taxes result from the inclusion of this subsidiary of ours, KKR Holdings will make payments to one of our subsidiaries in respect of those taxes.

        Certain interests in KKR Holdings that are held by our principals are subject to transfer restrictions and vesting requirements that, unless waived, modified or amended limit the ability of our principals to cause KKR Group Partnership Units to be exchanged under the exchange agreement so long as applicable vesting and transfer restrictions apply. The general partner of KKR Holdings, which is controlled by our founders, will have sole authority for waiving any applicable vesting or transfer restrictions.

        As contemplated by the exchange agreement, a coordinated selling program has been established relating to sales of common units received pursuant to the exchanges by holders of KKR Holdings units. Pursuant to the program, sales generally take place quarterly, and management is permitted to establish an overall limit on such sales based upon the trading volume of our common units or any other factor that may be considered relevant.

Registration Rights Agreement

        In connection with our NYSE listing, we entered into a registration rights agreement with KKR Holdings pursuant to which we granted KKR Holdings, its affiliates and transferees of its KKR Group Partnership Units the right, under certain circumstances and subject to certain restrictions, to require us to register under the Securities Act our common units (and other securities convertible into or exchangeable or exercisable for our common units) held or acquired by them. Under the registration rights agreement, holders of registration rights will have the right to request us to register the sale of their common units and also have the right to require us to make available shelf registration statements permitting sales of common units into the market from time to time over an extended period. In addition, holders of registration rights will have the ability to exercise certain piggyback registration

259

Table of Contents

rights in connection with registered offerings requested by other holders of registration rights or initiated by us. On October 1, 2010, the registration statement we filed pursuant to this agreement was declared effective, and a post-effective amendment was declared effective on September 21, 2011. As of December 31, 2012, 432,553,276 common units remain unissued under that registration statement.

Tax Receivable Agreement

        We and one or more of our intermediate holding companies may be required to acquire KKR Group Partnership Units from time to time pursuant to our exchange agreement with KKR Holdings. KKR Management Holdings L.P. has made and in the future intends to continue to make an election under Section 754 of the Internal Revenue Code in effect for each taxable year in which an exchange of KKR Group Partnership Units for common units occurs. Certain of these exchanges are expected to result in an increase in certain of our intermediate holding companies' share of the tax basis of the tangible and intangible assets of the KKR Group Partnerships, primarily attributable to a portion of the goodwill inherent in our business, that would not otherwise have been available. This increase in tax basis may increase depreciation and amortization deductions for tax purposes and therefore reduce the amount of income tax our intermediate holding companies would otherwise be required to pay in the future. This increase in tax basis may also decrease gain (or increase loss) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets.

        We have entered into a tax receivable agreement with KKR Holdings requiring the intermediate holding company to pay to KKR Holdings or transferees of its KKR Group Partnership Units 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax that the intermediate holding companies actually realize as a result of this increase in tax basis, as well as 85% of the amount of any such savings the intermediate holding companies actually realize as a result of increases in tax basis that arise due to future payments under the agreement. A termination of the agreement or a change of control could give rise to similar payments based on tax savings that we would be deemed to realize in connection with such events. This payment obligation is an obligation of the intermediate holding companies and not of either KKR Group Partnership. As such, the cash distributions to common unitholders may vary from holders of KKR Group Partnership Units (held by KKR Holdings and others) to the extent payments are made under the tax receivable agreements to exchanging holders of KKR Group Partnership Units. As the payments reflect actual tax savings received by KKR entities, there may be a timing difference between the tax savings received by KKR entities and the cash payments to exchanging holders of KKR Group Partnership Units. We expect the intermediate holding companies to benefit from the remaining 15% of cash savings, if any, in income tax that it realizes. In the event that other of our current or future subsidiaries become taxable as corporations and acquire KKR Group Partnership Units in the future, or if we become taxable as a corporation for U.S. federal income tax purposes, we expect that each will become subject to a tax receivable agreement with substantially similar terms.

        For purposes of the tax receivable agreement, cash savings in income tax will be computed by comparing the actual income tax liability of our subsidiary to the amount of such taxes that the intermediate holding companies would have been required to pay had there been no increase to the tax basis of the tangible and intangible assets of the KKR Group Partnerships as a result of the exchanges of KKR Group Partnership Units and had the intermediate holding companies not entered into the tax receivable agreement. The term of the tax receivable agreement continues until all such tax benefits have been utilized or expired, unless the intermediate holding companies exercise their right to terminate the tax receivable agreement for an amount based on the agreed payments remaining to be made under the agreement.

        Estimating the amount of payments that may be made under the tax receivable agreement is by its nature imprecise, insofar as the calculation of amounts payable depends on a variety of factors. The

260

---

Table of Contents

actual increase in tax basis, as well as the amount and timing of any payments under the tax receivable agreement, will vary depending upon a number of factors, including:

•

the timing of exchanges—for instance, the increase in any tax deductions will vary depending on the fair market value, which may fluctuate over time, of the KKR Group Partnership Units, which will depend on the fair market value of the depreciable or amortizable assets of the KKR Group Partnerships at the time of the transaction;



•

the price of our common units at the time of the exchange—the increase in any tax deductions, as well as the tax basis increase in other assets, of the KKR Group Partnerships, is directly proportional to the price of our common units at the time of the exchange;



•

the extent to which such exchanges are taxable—if an exchange is not taxable for any reason (for instance, in the case of a charitable contribution), increased deductions will not be available; and



•

the amount of tax, if any, our intermediate holding company is required to pay aside from any tax benefit from the exchanges, and the timing of any such payment. If our intermediate holding companies do not have taxable income aside from any tax benefit from the exchanges, it will not be required to make payments under the tax receivable agreement for that taxable year because no tax savings will have been actually realized.

        We expect that as a result of the amount of the increases in the tax basis of the tangible and intangible assets of the KKR Group Partnerships, assuming no material changes in the relevant tax law and that we earn sufficient taxable income to realize the full tax benefit of the increased amortization of our assets, future payments under the tax receivable agreement will be substantial. The payments under the tax receivable agreement are not conditioned upon our principals' continued ownership of us and are required to be made within 90 days of the filing of the tax return of KKR Management Holdings Corp. For the year ended December 31, 2012 such payments made to our principals, none of whom included a member of the board of directors of our Managing Partner or our named executive officers, were approximately $2.7 million.

        The intermediate holding companies may terminate the tax receivable agreement at any time by making an early termination payment to KKR Holdings or its transferees, based upon the net present value (based upon certain assumptions in the tax receivable agreement) of all tax benefits that would be required to be paid by the intermediate holding companies to KKR Holdings or its transferees. In addition, the tax receivable agreement provides that upon certain mergers, asset sales, other forms of combination transactions or other changes of control, the minimum obligations of our intermediate holding companies or their successor with respect to exchanged or acquired KKR Group Partnership Units (whether exchanged or acquired before or after such transaction) would be based on certain assumptions, including that our intermediate holding companies would have sufficient taxable income to fully utilize the increased tax deductions and increased tax basis and other benefits related to entering into the tax receivable agreement. In these situations, our obligations under the tax receivable agreement could have a substantial negative impact on our liquidity.

        Decisions made by our senior principals in the course of running our business, such as with respect to mergers, asset sales, other forms of business combinations or other changes of control, may influence the timing and amount of payments that are received by an exchanging or selling holder of partner interests in the KKR Group Partnerships under the tax receivable agreement. For example, the earlier disposition of assets following an exchange or acquisition transaction will generally accelerate payments under the tax receivable agreement and increase the present value of such payments, and the disposition of assets before an exchange or acquisition transaction will increase a principals' tax liability without giving rise to any rights of a principal to receive payments under the tax receivable agreement.

        Payments under the tax receivable agreement will be based upon the tax reporting positions that our Managing Partner will determine. We are not aware of any issue that would cause the IRS to challenge a tax basis increase. However, neither KKR Holdings nor its transferees will reimburse us for any payments previously made under the tax receivable agreement if such tax basis increase, or the tax benefits we claim arising from such increase, is successfully challenged by the IRS. As a result, in certain circumstances payments to KKR Holdings or its transferees under the tax receivable agreement could be in excess of the intermediate holding company's cash tax savings. The intermediate holding company's ability to achieve benefits from any tax basis increase, and the payments to be made under this agreement, will depend upon a number of factors, as discussed above, including the timing and amount of our future income.

KKR Group Partnership Agreements

        We indirectly control the general partners of the KKR Group Partnerships and, through the KKR Group Partnerships and their subsidiaries, the KKR business. Because our Managing Partner operates and controls us, our Managing Partner's board of directors and our officers are ultimately responsible for all material decisions of the KKR Group Partnerships and the KKR Group Partnerships' businesses.

        Pursuant to the partnership agreements of the KKR Group Partnerships, our partnership, as the controlling general partner of KKR Fund Holdings L.P. and KKR Management Holdings L.P., have the indirect right to determine when distributions will be made to the holders of KKR Group Partnership Units and the amount of any such distributions.

        The partnership agreements of the KKR Group Partnerships provide for tax distributions to the holders of KKR Group Partnership Units if the general partners of the KKR Group Partnerships determine that distributions from the KKR Group Partnerships would otherwise be insufficient to cover the tax liabilities of a holder of a KKR Group Partnership Unit. Generally, these tax distributions will be computed based on our estimate of the net taxable income of the relevant partnership allocable to a holder of a KKR Group Partnership Unit multiplied by an assumed tax rate equal to the highest effective marginal combined U.S. federal, state and local income tax rate prescribed for an individual or corporate resident in New York, New York (taking into account the nondeductibility of certain expenses and the character of our income).

        The partnership agreements of the KKR Group Partnerships authorize the general partners of the KKR Group Partnerships to issue an unlimited number of additional securities of the KKR Group Partnerships with such designations, preferences, rights, powers and duties that are different from, and may be senior to, those applicable to the KKR Group Partnerships Units, and which may be exchangeable for KKR Group Partnership Units.

Firm Use of Private Aircraft

        Certain of our senior principals, including Messrs. Kravis and Roberts, own aircraft that we use for business purposes in the ordinary course of our operations. These senior principals paid for the purchase of these aircraft with their personal funds and bear all operating, personnel and maintenance costs associated with their operation. The hourly rates that we pay for the use of these aircraft are based on current market rates for chartering private aircraft of the same type. We paid $4.6 million for the use of these aircraft during the year ended December 31, 2012, of which $3.2 million was paid to entities collectively controlled by Messrs. Kravis and Roberts.

Side-By-Side and Other Investments

        Because fund investors typically are unwilling to invest their capital in a fund unless the fund's manager also invests its own capital in the fund's investments, our investment fund documents generally require the general partners of our investment funds to make minimum capital commitments to the funds. The amount of these commitments, which are negotiated by fund investors, generally range from

262

---

Table of Contents

2% to 4% of a fund's total capital commitments at final closing. When investments are made, the general partner contributes capital to the fund based on its fund commitment percentage and if applicable, acquires a capital interest in the investment that is not subject to a carried interest. Historically, these capital contributions have been funded with cash from operations that otherwise would be distributed to our principals and by our principals.

        In connection with the KPE Transaction, we did not acquire capital interests in investments that were funded by our principals or others involved in our business prior to October 1, 2009. Rather, those capital interests were allocated to our principals or others involved in our business and are reflected in our financial statements as noncontrolling interests in consolidated entities to the extent that we hold the general partner interest in the fund. Any capital contributions that our private equity fund general partners are required to make to a fund will be funded by us and we will be entitled to receive our allocable share of the returns thereon.

        In addition, our principals and certain other qualifying employees are permitted to invest and have invested their own capital in side-by-side investments with our funds. Side-by-side investments are investments made on the same terms and conditions as those available to the applicable fund, except that these side-by-side investments are not subject to management fees or a carried interest. The cash invested by our executive officers and their investment vehicles aggregated to $27.2 million for the year ended December 31, 2012, of which $8.8 million, $16.4 million, $1.0 million and $1.0 million was invested by Messrs. Kravis, Roberts, Fisher and Janetschek, respectively. Mr. Sorkin had invested a de minimis amount in such investments for the year ended December 31, 2012. These investments are not included in the accompanying consolidated financial statements.

Indemnification of Directors, Officers and Others

        Under our partnership agreement, in most circumstances we will indemnify the following persons, to the fullest extent permitted by law, from and against all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts: our Managing Partner; any departing Managing Partner; any person who is or was an affiliate of our Managing Partner or any departing Managing Partner; any person who is or was a member, partner, tax matters partner, officer, director, employee, agent, fiduciary or trustee of our partnership or our subsidiaries, the general partner or any departing general partner or any affiliate of us or our subsidiaries, our Managing Partner or any departing Managing Partner; any person who is or was serving at the request of a Managing Partner or any departing Managing Partner or any affiliate of a Managing Partner or any departing Managing Partner as an officer, director, employee, member, partner, agent, fiduciary or trustee of another person; or any person designated by our Managing Partner. We have agreed to provide this indemnification unless there has been a final and non-appealable judgment by a court of competent jurisdiction determining that these persons acted in bad faith or engaged in fraud or willful misconduct. We have also agreed to provide this indemnification for criminal proceedings. Any indemnification under these provisions will only be out of our assets. Unless it otherwise agrees, our Managing Partner will not be personally liable for, or have any obligation to contribute or loan funds or assets to us to enable us to effectuate, indemnification. The indemnification of the persons described above shall be secondary to any indemnification such person is entitled from another person or the relevant KKR fund to the extent applicable. We may purchase insurance against liabilities asserted against and expenses incurred by persons in connection with our activities, regardless of whether we would have the power to indemnify the person against liabilities under our partnership agreement.

        Each member of the board of directors (each an "Indemnitee") has entered into an indemnification agreement with the Managing Partner and us. Each indemnification agreement provides that the Indemnitee, subject to the limitations set forth in each indemnification agreement, shall be indemnified and held harmless by the Managing Partner on an after tax basis from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and

263

Table of Contents

expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all threatened, pending or completed claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, and whether formal or informal and including appeals, in which the Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of being or having been or having agreed to serve as a member of the board of directors, or while serving as a member of the board of directors, being or having been serving or having agreed to serve at the request of the Managing Partner as a director, officer, employee or agent (which, for purposes hereof, shall include a trustee, partner or manager or similar capacity) of another corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise, whether arising from acts or omissions to act occurring on, before or after the date of such indemnification agreement. Each indemnification agreement provides that the Indemnitee shall not be indemnified and held harmless if there has been a final and non-appealable judgment entered by an arbitral tribunal or court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to the indemnification agreement, the Indemnitee acted in bad faith or engaged in fraud or willful misconduct.

Guarantee of Contingent Obligations to Fund Partners; Indemnification

        The partnership documents governing our carry paying funds, including funds and vehicles relating to private equity, mezzanine, infrastructure, special situations investments, generally include a "clawback" provision that, if triggered, may give rise to a contingent obligation requiring the general partner to return or contribute amounts to the fund for distribution to its investors at the end of the life of the fund. Under a "clawback" obligation, upon the liquidation of a fund, the general partner is required to return, typically, on an after-tax basis, previously distributed carry to the extent that, due to the diminished performance of later investments, the aggregate amount of carry distributions received by the general partner during the term of the fund exceed the amount to which the general partner was ultimately entitled, including the effects of any performance hurdles. Excluding carried interest received by the general partners of funds that were not contributed to KKR in the KPE Transaction, as of December 31, 2012, no carried interest was subject to this clawback obligation, assuming that all applicable private equity funds were liquidated at their December 31, 2012 fair values. Had the investments in such funds been liquidated at zero value, the clawback obligation would have been $1,095.4 million.

        Certain private equity funds that were contributed to us in the KPE Transaction also include a "net loss sharing provision." Upon the liquidation of an investment vehicle to which a net loss sharing obligation applies, the general partner is required to contribute capital to the vehicle, to fund 20% of the net losses on investments. In these vehicles, such losses would be required to be paid by us to the limited partners in those vehicles in the event of a liquidation of the fund regardless of whether any carried interest had previously been distributed, and a greater share of the investment losses would be allocable to us relative to capital that we contributed to it as the general partner. Based on the fair market values as of December 31, 2012, there would have been no net loss sharing obligation. If the net loss sharing vehicles were liquidated at zero value, the contingent repayment obligation in connection with the net loss sharing provision as of December 31, 2012 would have been approximately $616.7 million.

        Prior to the KPE Transaction, certain KKR principals who received carried interest distributions with respect to the certain private equity funds contributed to us had personally guaranteed, on a several basis and subject to a cap, the contingent obligations of the general partners of such private equity funds to repay amounts to fund limited partners pursuant to the general partners' clawback obligations. The terms of the KPE Transaction require that our principals remain responsible for any clawback obligations relating to carry distributions received prior to the KPE Transaction, up to a maximum of $223.6 million. Carry distributions arising subsequent to the KPE Transaction may give rise to clawback obligations that may be allocated generally to us and to our principals who participate

264

Table of Contents

in the carry pool . Unlike the clawback obligation, we will be responsible for amounts due under a net loss sharing obligation and will indemnify our principals for any personal guarantees that they have provided with respect to such amounts. In addition, guarantees of or similar arrangements relating to, clawback or net loss sharing obligations in favor of third party investors in an individual investment partnership by entities we own may limit distributions of carried interest more generally.

Facilities

        Certain trusts, whose beneficiaries include children of Mr. Kravis and Mr. Roberts, and certain other senior principals who are not executive officers of the Company, are partners in a real-estate based partnership that maintains an ownership interest in our Menlo Park location. Payments made from us to this partnership aggregated $6.8 million for the year ended December 31, 2012.

Confidentiality and Restrictive Covenant Agreements

        Our principals have entered into confidentiality and restrictive covenant agreements that include prohibitions on our principals competing with us or soliciting certain fund investors or senior-level employees of our firm and specified subsidiaries and affiliates during a restricted period following their departure from the firm. For further information on these agreements, see "Executive Compensation—Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards in 2012—Terms of Confidentiality and Restrictive Covenant Agreements."

Transactions with other Related Persons

        We have and may in the future continue to enter into ordinary course transactions with unaffiliated entities known to us to beneficially own more than 5% of any class of the outstanding voting securities of our partnership. These transactions may include investments by them in our funds generally on the same terms and conditions offered to other unaffiliated fund investors and participation in our capital markets transactions, including underwritings and syndications, generally on the same terms and conditions offered to other unaffiliated capital markets participants. See "Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters."

Statement of Policy Regarding Transactions with Related Persons

        The board of directors of our Managing Partner adopted a written statement of policy for our partnership regarding transactions with related persons, which we refer to as our related person policy. Our related person policy requires that a "related person" (as defined as in Item 404(a) of Regulation S-K) must promptly disclose to our General Counsel or other designated person any "related person transaction" (defined as any transaction, arrangement or relationship, or series of similar transactions, arrangements or relationships, including, without limitation, any loan, guarantee of indebtedness, transfer or lease of real estate, or use of company property) that is reportable by us under Item 404(a) of Regulation S-K in which we were or are to be a participant and the amount involved exceeds $120,000 and in which any related person had or will have a direct or indirect material interest) and all material facts with respect thereto. Those individuals will then communicate that information to the board of directors of our Managing Partner. No related person transaction will be consummated without the approval or ratification of a committee of the board consisting exclusively of disinterested directors; provided, however, the conflicts committee of our board of directors has pre-approved certain ordinary course transactions with persons known to us to beneficially own more than 5% of our outstanding common units on terms generally not less favorable as obtained from other third parties, including investments in our funds as limited partners and participation in capital markets transactions like underwritings and syndications. It is our policy that directors interested in a related person transaction will recuse themselves from any vote on a related person transaction in which they have an interest. All transactions entered into prior to July 14, 2010 were not approved in accordance with this policy as they were entered into prior to the date of adoption of the policy. All side-by-side
