Note 2.

Investment in Unconsolidated Affiliate

The Company has an investment in the general partnership LSV Asset Management (LSV). LSV is a registered investment advisor that provides investment advisory services to institutions, including pension plans and investment companies. LSV is currently an investment sub-advisor for a small number of SEI-sponsored mutual funds. As of March 31, 2012, the Company’s total partnership interest in LSV was approximately 41 percent. The Company accounts for its interest in LSV using the equity method because of its less than 50 percent ownership. The Company’s interest in the net assets of LSV is reflected in Investment in unconsolidated affiliate on the accompanying Consolidated Balance Sheets and its interest in the earnings of LSV is reflected in Equity in earnings of unconsolidated affiliate on the accompanying Consolidated Statements of Operations.

At March 31, 2012, the Company’s total investment in LSV was $66,691. The investment in LSV exceeded the underlying equity in the net assets of LSV by $3,608, of which $3,062 is considered goodwill embedded in the investment. The Company receives partnership distributions from LSV on a quarterly basis. The Company received partnership distribution payments from LSV for $21,593 and $23,802 in the three months ended March 31, 2012 and 2011, respectively.

The Company’s proportionate share in the earnings of LSV was $27,330 and $28,949 during the three months ended March 31, 2012 and 2011, respectively.

Page 8 of 37

The following table contains the condensed statements of operations of LSV for the three months ended March 31, 2012 and 2011:


	Three Months Ended March 31,
	2012		2011
Revenues	$	77,465	$	79,402
Net income		66,673		69,946

In March 2009, certain partners (the Contributing partners) of LSV, including the Company, designated a portion of their partnership interest for the purpose of providing an interest in the partnership to a select group of key employees. Until such time an interest in the partnership is issued to a key employee, all profits, losses, distributions and other rights and obligations relating to such unissued interests remains with the Contributing partners. Each issuance must be authorized by unanimous vote of all Contributing partners. In April 2012, the Contributing partners agreed to provide certain key employees an interest in LSV, thereby reducing the Company’s interest in LSV to slightly under 40 percent.

Guaranty Agreement

In April 2011, LSV Employee Group II, LLC agreed to purchase a partnership interest of an existing LSV employee for $4,300, of which $3,655 was financed through a term loan with Bank of America, N.A. (Bank of America). The Company provided an unsecured guaranty to the lenders of all the obligations of LSV Employee Group II, LLC. The lenders have the right to seek payment from the Company in the event of a default by LSV Employee Group II, LLC. The term loan has a four year term and will be repaid from the quarterly distributions of LSV. LSV Employee Group II made principal payments of $219 during the three months ended March 31, 2012. As of March 31, 2012, the remaining unpaid principal balance of the term loan was $2,978. This amount is not reflected, nor is it required to be reflected, in the Company’s Consolidated Balance Sheet at March 31, 2012.

The Company’s direct interest in LSV is unchanged as a result of this transaction. The Company has determined that LSV Employee Group II is a variable interest entity (VIE); however, the Company is not considered the primary beneficiary because it does not have the power to direct the activities that most significantly impact the economic performance of LSV Employee Group II either directly or through any financial responsibility from the guaranty.

In April 2012, LSV Employee Group II made a principal payment of $249. As of April 30, 2012, the remaining unpaid principal balance of the term loan was $2,729. The Company, in its capacity as guarantor, currently has no obligation of payment relating to the term loan of LSV Employee Group II and, furthermore, fully expects that LSV Employee Group II will meet all of their future obligations regarding the term loan.

Note 3.

Variable Interest Entities – Investment Products

The Company has created numerous investment products for its clients in various types of legal entity structures. The Company serves as the Manager, Administrator and Distributor for these investment products and may also serve as the Trustee for some of the investment products. Clients are the equity investors and participate in proportion to their ownership percentage in the net income and net capital gains of the products, and, on liquidation, will participate in proportion to their ownership percentage in the remaining net assets of the products after satisfaction of outstanding liabilities. Some of the Company’s investment products have been determined to be VIEs at inception.

The Company does not have a significant equity investment in any of the VIEs and does not have an obligation to enter into any guarantee agreements with the VIEs. The Company is not the primary beneficiary of the VIEs because the expected fees and the expected return on any investment into the VIE by the Company relative to the expected returns of the VIE to the equity investor holders does not approach 50 percent of the expected losses or gains of the VIEs. Therefore, the Company is not required to consolidate any investment products that are VIEs into its financial statements. The Company’s variable interest in the VIEs, which consists of management fees and in some situations, seed capital, is not considered a significant variable interest.

The risks to the Company associated with its involvement with any of the investment products that are VIEs are limited to the cash flows received from the revenue generated for asset management, administration and distribution services and any equity investments in the VIEs. Both of these items are not significant. The Company has no other financial obligation to the VIEs.

Amounts relating to fees received from the VIEs included in Receivables and amounts relating to equity investments in the VIEs included in Investments Available for Sale on the Company’s Consolidated Balance Sheets are not significant to the total assets of the Company.

Note 5.

Fair Value Measurements

The fair value of the Company’s financial assets and liabilities is determined in accordance with the fair value hierarchy. The fair value of the Company’s Level 1 and Level 2 financial assets consist mainly of investments in equity and fixed-income mutual funds that are quoted daily and Government National Mortgage Association (GNMA) and other U.S. government agency securities that are single issuer pools that are valued based on current market data for the specific issue owned or pools of similar securities. Level 3 financial assets primarily consist of senior note obligations issued by SIVs. The Company did not have any Level 3 financial liabilities at March 31, 2012 or December 31, 2011. There were no transfers of financial assets between levels within the fair value hierarchy during the three months ended March 31, 2012.

Valuation of SIV Securities

The underlying collateral of the SIV securities is mainly comprised of asset-backed securities and collateralized debt obligations. The Company utilizes the services of a third party independent firm to assist in determining the fair value of the SIV security owned. Given the lack of any reliable market data on the SIV security, the firm utilized a valuation model that employs a net asset approach which considers the value of the underlying collateral of the SIV security to determine its fair value. Management evaluated the value received from the firm and considered other information, such as the existence of any current market activity, to determine the fair value of the SIV securities. As a result of this evaluation, the Company utilized the fair value of the SIV security without adjustment as provided by the third party firm.

The model used by the independent valuation firm to determine the fair value of the SIV security attempts to value the underlying collateral of the SIV security through the use of industry accepted and proprietary valuation techniques and models. This approach combines advanced analytics with real-time market information that incorporate structural and fundamental analysis, collateral characteristics and recent market developments. Each security that makes up the underlying collateral is specifically identified by its CUSIP or ISIN number and is analyzed by using observable collateral characteristics and credit statistics in order to project future performance and expected cash flows for each individual security. The projected cash flows incorporate assumptions and expectations based upon the foregoing analysis of the collateral characteristics such as, but not limited to, default probabilities, recovery rates, prepayment speeds and loss severities. Expected future cash flows are discounted at an appropriate yield derived from the individual security, structural and collateral characteristics, trading levels and other available market data. Different modeling techniques and associated inputs and assumptions may be used to project future cash flows for each security depending upon the asset classification of that individual security (i.e. residential mortgage-backed security, commercial mortgage-backed security, collateralized debt obligations, etc.). The

Page 11 of 37

aggregate value of the discounted cash flows of the underlying collateral is compared to the total remaining par value of the collateral to determine the expected recovery price, or fair value, of the remaining note obligations. Other factors may be considered that are specific to the SIV security that may affect the fair value of the SIV security.

Management may also consider, when available, price quotes from brokers and dealers. If a price quote is available, management will compare this number to the fair value derived from the valuation model of the independent firm giving consideration to other market factors and risk premiums. Given the lack of any significant trading activity for the SIV security owned by the Company, management believes that market prices may not represent the implied fair value of the SIV security owned by the Company.

In the event a market transaction does exist for a SIV security, management evaluates the publicly available information surrounding the transaction in order to assess if the price used represents the fair value for the SIV security. In management’s opinion, the current market for SIV securities does not represent any orderly and efficient market.

The fair value of certain financial assets and liabilities of the Company was determined using the following inputs:

Lines of Credit

On February 2, 2012 (the Closing Date), the Company entered into a new five-year $300,000 Credit Agreement (the Credit Facility) with Wells Fargo Bank, National Association, and a syndicate of other lenders. The Credit Facility became available on the Closing Date and replaced the five-year Credit Agreement with JP Morgan Chase Bank, N.A. The Credit Facility is scheduled to expire in February 2017, at which time any aggregate principal amount of loans outstanding becomes payable in full. Any borrowings made under the Credit Facility will accrue interest at 1.250 percent above LIBOR. There is also a commitment fee equal to 0.15 percent per annum on the daily unused portion of the facility. The aggregate amount of the Credit Facility may be increased by an additional $100,000 under certain conditions set forth in the agreement. The Credit Facility contains covenants that restrict the ability of the Company to engage in mergers, consolidations, asset sales, investments, transactions with affiliates, or to incur liens, as defined in the agreement. In the event of a default under the Credit Facility, the Company would also be restricted from paying dividends on, or repurchasing, its common stock without the approval of the lenders. None of the covenants of the Credit Facility negatively affect the Company’s liquidity or capital resources. Both the interest rate and commitment fee prices may increase if the Company’s leverage ratio reaches certain levels. Upon the occurrence of certain financial or economic events, significant corporate events, or certain other events of default constituting an event of default under the Credit Facility, all loans outstanding may be declared immediately due and payable and all commitments under the agreement may be terminated. The Company had no borrowings through the Credit Facility at March 31, 2012. The Company was in compliance with all covenants of the Credit Facility at March 31, 2012.

The Company’s Canadian subsidiary has a credit facility agreement (the Canadian Credit Facility) for the purpose of facilitating the settlement of mutual fund transactions. The Canadian Credit Facility has no stated expiration date. The amount of the facility is limited to $2,000 Canadian dollars or the equivalent amount in U.S. dollars. The Canadian Credit Facility does not contain any covenants which restrict the liquidity or capital resources of the Company. The Company had no borrowings under the Canadian Credit Facility and was in compliance with all covenants during the three months ended March 31, 2012.

Shareholders’ Equity

Stock-Based Compensation

The Company currently has one active equity compensation plan, the 2007 Equity Compensation Plan (the 2007 Plan), which provides for the grant of incentive stock options, non-qualified stock options and stock appreciation rights with respect to up to 20 million shares of common stock of the Company, subject to adjustment for stock splits, reclassifications, mergers and other events. Permitted grantees under the 2007 Plan include employees, non-employee directors and consultants who perform services for the Company. The plan is administered by the Compensation Committee of the Board of Directors of the Company. The Company has only granted non-qualified stock options under the plan. All outstanding stock options have performance-based vesting provisions specific to each option grant that tie the vesting of the applicable stock options to the Company’s financial performance. The Company’s stock options vest at a rate of 50 percent when specified diluted earnings per share targets are achieved, and the remaining 50 percent when secondary, higher specified diluted earnings per share targets are achieved. The amount of stock-based compensation expense is based upon management’s estimate of when the earnings per share targets may be achieved.

The Company discontinued any further grants under the Company’s 1998 Equity Compensation Plan (the 1998 Plan) as a result of the approval of the 2007 Plan. No options are available for grant from this plan. Grants made from the 1998 Plan continue in effect under the terms of the grant.

The Company recognized stock-based compensation expense in its Consolidated Financial Statements in the three months ended March 31, 2012 and 2011, respectively, as follows:


	Three Months Ended March 31,
	2012			2011

Stock-based compensation expense	$	4,033		$	3,732
Less: Deferred tax benefit		(1,521	)		(1,398	)


Stock-based compensation expense, net of tax	$	2,512		$	2,334

As of March 31, 2012, there was approximately $45,594 of unrecognized compensation cost remaining, adjusted for estimated forfeitures, related to unvested employee stock options that management expects will vest and is being amortized. The Company estimates that compensation cost will be recognized according to the following schedule:


Period	Stock-Based Compensation Expense

Remainder of 2012	$	11,837
2013		12,715
2014		12,521

The Company issues new common shares associated with the exercise of stock options. The total intrinsic value of options exercised during the three months ended March 31, 2012 was $3,752. The total options exercisable as of March 31, 2012 had an intrinsic value of $36,218. The total intrinsic value for options exercisable is calculated as the difference between the market value of the Company’s common stock as of March 31, 2012 and the exercise price of the shares. The market value of the Company’s common stock as of March 31, 2012 was $20.69 as reported by the Nasdaq Stock Market, LLC. The weighted average exercise price of the options exercisable as of March 31,

Page 16 of 37

2012 was $17.36. Total options that were outstanding and exercisable as of March 31, 2012 were 26,082,000 and 10,873,000, respectively.

Common Stock Buyback

The Company’s Board of Directors, under multiple authorizations, has authorized the repurchase of the Company’s common stock on the open market or through private transactions. The Company purchased 1,848,000 shares at a total cost of $37,714 during the three months ended March 31, 2012. As of March 31, 2012, the Company has $58,562 of authorization remaining for the purchase of common stock under the program.

The Company immediately retires its common stock when purchased. Upon retirement, the Company reduces Capital in excess of par value for the average capital per share outstanding and the remainder is charged against Retained earnings. If the Company reduces its Retained earnings to zero, any subsequent purchases of common stock will be charged entirely to Capital in excess of par value.

Income Taxes

The gross liability for unrecognized tax benefits at March 31, 2012 and December 31, 2011 was $11,757 and $9,410, respectively, exclusive of interest and penalties, of which $10,043 and $8,320 would affect the effective tax rate if the Company were to recognize the tax benefit.

The Company classifies interest and penalties on unrecognized tax benefits as income tax expense. As of March 31, 2012 and December 31, 2011, the combined amount of accrued interest and penalties related to tax positions taken on tax returns was $843 and $634, respectively.

Amount included in Other long-term liabilities		10,832		8,276


	$	12,600	$	10,044

The Company’s effective tax rates were 37.2 percent and 37.1 percent for the three months ended March 31, 2012 and 2011, respectively. The Company files income tax returns in the United States on a consolidated basis and in many U.S. state and foreign jurisdictions. The Company is subject to examination of income tax returns by the Internal Revenue Service (IRS) and other domestic and

Page 20 of 37

foreign tax authorities. The Company is no longer subject to U.S. federal income tax examination for years before 2007 and is no longer subject to state, local or foreign income tax examinations by authorities for years before 2006.

The Company estimates it will recognize $1,768 of unrecognized tax benefits within the next twelve months due to the expiration of the statute of limitations and resolution of income tax audits. These unrecognized tax benefits are related to tax positions taken on certain federal, state, and foreign tax returns. However, the timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year. While it is reasonably possible that some issues under examination could be resolved in the next twelve months, based upon the current facts and circumstances, the Company cannot reasonably estimate the timing of such resolution or total range of potential changes as it relates to the current unrecognized tax benefits that are recorded as part of the Company’s financial statements.

Note 12.

Commitments and Contingencies

In the normal course of business, the Company is party to various claims and legal proceedings.

One of SEI’s principal subsidiaries, SIDCO, has been named as a defendant in certain putative class action complaints (the Complaints) related to leveraged exchange traded funds (ETFs) advised by ProShares Advisors, LLC. The first complaint was filed on August 5, 2009. To date, the Complaints have been filed in the United States District Court for the Southern District of New York and in the United States District Court for the District of Maryland. The three complaints filed in the District of Maryland have been voluntarily dismissed by the plaintiffs. Two of them were subsequently re-filed in the Southern District of New York. Two of the complaints filed in the Southern District of New York have also been voluntarily dismissed by plaintiffs. The Complaints are purportedly made on behalf of all persons that purchased or otherwise acquired shares in various ProShares leveraged ETFs pursuant or traceable to allegedly false and misleading registration statements, prospectuses and statements of additional information. The Complaints name as defendants ProShares Advisors, LLC; ProShares Trust; ProShares Trust II, SIDCO, and various officers and trustees to ProShares Advisors, LLC; ProShares Trust and ProShares Trust II. The Complaints allege that SIDCO was the distributor and principal underwriter for the various ProShares leveraged ETFs that were distributed to authorized participants and ultimately shareholders. The complaints allege that the registration statements for the ProShares ETFs were materially false and misleading because they failed adequately to describe the nature and risks of the investments. The Complaints allege that SIDCO is liable for these purportedly material misstatements and omissions under Section 11 of the Securities Act of 1933. The Complaints seek unspecified compensatory and other damages, reasonable costs and other relief. Defendants have moved to consolidate the complaints, which motion has been granted. The Court appointed lead plaintiff on July 13, 2010, and an amended consolidated class action complaint was filed on September 25, 2010 asserting substantially the same claims. Defendants moved to dismiss on November 15, 2010. On December 16, 2010, lead plaintiff informed the Court and Defendants that lead plaintiff elected to file a second amended consolidated complaint, which was filed on January 31, 2011. Defendants filed a motion to dismiss the second complaint on March 17, 2011. Oral argument on this motion was held on February 2, 2012. While the outcome of this litigation is uncertain given its early phase, SEI believes that it has valid defenses to plaintiffs’ claims and intends to defend the lawsuits vigorously.

to the role of SPTC in providing back-office services to Stanford Trust Company. The petitions allege that SEI and SPTC aided and abetted or otherwise participated in the sale of “certificates of deposit” issued by Stanford International Bank. Two of the five actions filed in East Baton Rouge have been removed to federal court, and plaintiffs’ motions to remand are pending. These two cases have been transferred by the Judicial Panel on Multidistrict Litigation to United States District Court for the Northern District of Texas. On August 31, 2011, the United States District Court for the Northern District of Texas issued an order and judgment that the causes of action alleged against SEI and SPTC in the two remanded actions were preempted by federal law and the Court dismissed these cases with prejudice. The Court of Appeals for the Fifth Circuit granted an expedited appeal of the United States District Court’s order and judgment. The appeal was briefed, and oral argument was held on February 7, 2012. On March 19, 2012, a panel of the Court of Appeals for the Fifth Circuit reversed the decision of the United States District Court and remanded the actions for further proceedings. On April 2, 2012, SEI filed with the United States Court of Appeals for the Fifth Circuit a petition for rehearing en banc of the panel’s opinion. On April 19, 2012, the Fifth Circuit Court of Appeals denied the petition for rehearing.

The case filed in Ascension Parish was also removed to federal court and transferred by the Judicial Panel on Multidistrict Litigation to the Northern District of Texas. The schedule for responding to that complaint has not yet been established. The plaintiffs in the remaining two cases in East Baton Rouge have granted SEI an extension to respond to the filings. SEI and SPTC filed exceptions in the putative class action pending in East Baton Rouge, which the Court granted in part and dismissed the claims under the Louisiana Unfair Trade Practices Act and denied in part as to the other exceptions. SEI and SPTC filed an answer to the East Baton Rouge putative class action; plaintiffs filed a motion for class certification; and SEI and SPTC also filed a motion for summary judgment against certain named plaintiffs which the Court stated will not be set for hearing until after the hearing on the class certification motion. Following the decision by the United States District Court for the Northern District of Texas, the Court in the East Baton Rouge action issued an order staying the proceedings in the East Baton Rouge class action pending the outcome of the appeal of the order and judgment of the United States District Court for the Northern District of Texas. Following the panel opinion of the Court of Appeals on March 19, 2012, the Court in the East Baton Rouge action scheduled a hearing on class certification for September 20, 2012. While the outcome of this litigation is uncertain given its early phase, SEI and SPTC believe that they have valid defenses to plaintiffs’ claims and intend to defend the lawsuits vigorously.

Because of the uncertainty of the make-up of the classes, the specific theories of liability that may survive a motion to dismiss, the lack of discovery regarding damages, causation, mitigation and other aspects that may ultimately bear upon loss, the Company is not reasonably able to provide an estimate of loss, if any, with respect to the foregoing lawsuits.

Overview

Consolidated Summary

We are a leading global provider of investment processing, investment management, and investment operations solutions. We help corporations, financial institutions, financial advisors, and ultra-high-net-worth families create and manage wealth by providing comprehensive, innovative, investment and investment-business solutions. Investment processing fees are earned as monthly fees for contracted services, including computer processing services, software licenses, and investment operations services, as well as transaction-based fees for providing securities valuation and trade-execution. Investment operations and investment management fees are earned as a percentage of average assets under management or administration. As of March 31, 2012, through our subsidiaries and partnerships in which we have a significant interest, we manage or administer $427.8 billion in mutual fund and pooled or separately managed assets, including $188.6 billion in assets under management and $239.2 billion in client assets under administration. Our affiliate, LSV Asset Management (LSV), manages $60.6 billion of assets which are included as assets under management.

In our opinion, the following items had a significant impact on our financial results for the three month periods ended March 31, 2012 and 2011:

•

Revenue growth was primarily driven by higher Asset management, administration and distribution fees from improved cash flows and market appreciation occurring in late 2011 and into the first quarter 2012. Our average assets under management, excluding LSV, increased $9.6 billion, or eight percent, to $124.1 billion in the first quarter 2012 as compared to $114.5 billion during the first quarter 2011.

•

New business coupled with asset funding from existing clients for our hedge fund solutions and increased accounts for our separately managed accounts solutions in our Investment Managers segment also served to drive revenue growth.

•

Our percentage ownership of LSV remained at approximately 41 percent. Our proportionate share in the earnings of LSV in the first quarter 2012 was $27.3 million, as compared to $28.9 million in first quarter 2011, a decrease of six percent. Despite the favorable market conditions in late 2011 and first quarter 2012, LSV’s revenues decreased due to cash outflows in early 2011 and the sharp market decline in third quarter 2011 which resulted in a net decline in the value of assets under management. LSV’s average assets under management were $59.2 billion during the first quarter 2012, as compared to $62.2 billion during the first quarter 2011, a decrease of five percent.

•

Our operating expenses related to servicing new and existing clients of our Global Wealth Services solution implemented on the Global Wealth Platform increased during the first quarter 2012 as compared to first quarter 2011 as we continue to build out the operational infrastructure and add new functionality to the platform. A higher portion of these costs are not capitalized. These increased operational costs, mainly related to personnel, primarily impacted the Private Banks and Investment Advisors segments. The increased operational costs are included in Compensation, benefits and other personnel on the accompanying Consolidated Statements of Operations.

•

Our operating expenses related to our hedge fund and separately managed accounts solutions of our Investment Managers segment increased during the first quarter 2012 as compared to first quarter 2011. These increased operational costs, mainly related to personnel, resulted from servicing new and existing clients and are also included in Compensation, benefits and other personnel on the accompanying Consolidated Statements of Operations.

•

Sales events, net of client losses, were significantly higher during the first quarter 2012. These sales events resulted in an increase in sales compensation expense of $1.8 million when compared to first quarter 2011.

•

We recognized $2.9 million in gains from structured investment vehicles (SIV) securities during the first quarter 2012 as compared to gains of $6.9 million during the first quarter 2011. Approximately $2.1 million of the gain in 2012 resulted from cash payments received from the SIV securities that had been previously written down.

•

We continued our stock repurchase program during 2012 and purchased 1,848,000 shares at an average price of approximately $20 per share in the first quarter of 2012.

Page 29 of 37

During the three months ended March 31, 2012, we recognized gains of $2.9 million from SIV securities, of which $2.1 million resulted from cash payments received from the SIV securities and $0.8 million from an increase in fair value at March 31, 2012.

During the three months ended March 31, 2011, we recognized gains of $6.9 million from SIV securities, of which $2.1 million resulted from cash payments received from the SIV securities and $4.8 million from an increase in fair value at March 31, 2011. In addition, we sold the senior note obligation originally issued by Stanfield Victoria. There was no gain or loss recognized from the sale of the note as the fair value of the Stanfield Victoria note at December 31, 2010 was not different than the sale price received.

Interest and dividend income

Interest and dividend income is earned based upon the amount of cash that is invested daily and the average yield earned on those balances.

Interest expense

Interest expense primarily includes fees related to our credit facility.

Equity in the earnings of unconsolidated affiliate

Equity in the earnings of unconsolidated affiliate on the accompanying Consolidated Statement of Operations includes our less than 50 percent ownership in LSV. Our total partnership interest in LSV remained at approximately 41 percent during the three month periods ended March 31, 2012 and 2011. Our proportionate share in the earnings of LSV was $27.3 million in first quarter 2012 as compared to $28.9 million in first quarter 2011, a decrease of six percent. LSV’s revenues decreased due to cash outflows in early 2011 coupled with the sharp market decline in third quarter 2011 despite improved capital market conditions in late 2011 and first quarter 2012. LSV’s ending assets under management decreased $1.8 billion to $60.6 billion at March 31, 2012 as compared to $62.4 billion at March 31, 2011, a decrease of three percent.

In March 2009, certain partners of LSV, including SEI, agreed to designate a portion of their partnership interest for the purpose of providing an interest in the partnership to a select group of key LSV employees. In April 2012, these contributing partners agreed to provide certain key LSV employees an interest in LSV thereby reducing our interest in LSV to slightly below 40 percent.

Noncontrolling interest

Noncontrolling interest includes the interest of other shareholders in a joint venture of the Company in an asset management firm located in South Korea.

Income Taxes

Our effective tax rates were 37.2 percent and 37.1 percent for the three months ended March 31, 2012 and 2011, respectively.

Fair Value Measurements

The fair value of our financial assets and liabilities is determined in accordance with the fair value hierarchy. The fair value of most of our financial assets are determined using Level 1 or Level 2 inputs and consist mainly of investments in equity or fixed-income mutual funds that are quoted daily and Government National Mortgage Association (GNMA) and other U.S. government agency securities that are single issuer pools that are valued based on current market data of similar assets. Our Level 3 financial assets consist mainly of SIV securities (See Note 5 to the Notes to Consolidated Financial Statements).

Liquidity and Capital Resources


	Three Months Ended March 31,
	2012			2011

Net cash provided by operating activities	$	39,224		$	58,336
Net cash (used in) provided by investing activities		(19,855	)		6,527
Net cash used in financing activities		(52,228	)		(63,116	)

Cash and cash equivalents, beginning of period		420,986			496,292

Cash and cash equivalents, end of period	$	388,127		$	498,039

Cash requirements and liquidity needs are primarily funded through our cash flow from operations and our capacity for additional borrowing. At March 31, 2012, our unused sources of liquidity consisted of cash and cash equivalents and the amount available under our credit facility.

In February 2012, we replaced our credit facility with a new five-year credit facility agreement which provides for borrowings of up to $300.0 million (See Note 7 to the Consolidated Financial Statements). The new credit facility is a senior unsecured revolving line of credit with Wells Fargo Bank, National Association, and a syndicate of other lenders and is scheduled to expire in February 2017. The availability of the new credit facility is subject to the compliance with certain covenants set forth in the agreement. The credit facility contains covenants which restrict our ability to engage in mergers, consolidations, asset sales, investments, transactions with affiliates, or to incur liens, as defined in the agreement. In the event of a default under the credit facility, we would also be restricted from paying dividends on, or repurchasing, our common stock. Currently, our ability to borrow from the credit facility is not limited by any covenant of the agreement. We currently have no borrowings under the new credit facility.

Our cash and cash equivalents include accounts managed by our subsidiaries and minority-owned subsidiaries that are used in their operations or to cover specific business and regulatory requirements. The availability of this cash for other purposes beyond the operations of these subsidiaries may be limited. As of April 30, 2012, the amount of cash and cash equivalents considered free and immediately accessible for other general corporate purposes was $262.9 million.

Cash flows from operations decreased $19.1 million in the first quarter of 2012 compared to the first quarter of 2011 due to the decline in net income and the net change in our working capital accounts, primarily from the change in the balances of receivables and accrued income taxes.

Cash flows from investing activities decreased $26.4 million in the first quarter of 2012 compared to the first quarter of 2011. Net cash used in investing activities includes:

•

Purchases, sales and maturities of marketable securities. We had cash outflows of $9.6 million for the purchase of marketable securities in the first quarter of 2012 as compared to $27.3 million in the first quarter of 2011. Marketable securities purchased in 2012 and 2011 consisted of investments for the start-up of new investment products and investments in short-term U.S. government agency and commercial paper securities by SIDCO. Purchases of marketable securities in first quarter 2011 include $20.0 million of short-term U.S. government agency and commercial paper securities to initiate SIDCO’s investment program. We had cash inflows of $11.2 million from sales and maturities of marketable securities in the first quarter of 2012 as compared to $46.9 million in the first quarter of 2011. Marketable securities sold in 2011 primarily includes the proceeds from the sales of SIV securities. Cash inflows from maturities and prepayments of marketable securities were $10.4 million in the first quarter of 2012 as compared to $10.1 million in the first quarter of 2011.

•

The capitalization of costs incurred in developing computer software. We will continue the development of the Global Wealth Platform through a series of releases to expand the functionality of the platform. We capitalized $9.3 million of software development costs in the first quarter of 2012 as compared to $10.7 million in the first quarter of 2011. Amounts capitalized in 2012 and 2011 include costs for significant enhancements and upgrades to the platform.

•

Capital expenditures. Our capital expenditures in the first quarter of 2012 primarily include purchased software. Our capital expenditures in the first quarter of 2011 primarily include equipment for our data center operations.

Cash flows from financing activities increased $10.9 million in the first quarter of 2012 compared to the first quarter of 2011. Net cash used in financing activities includes:

•

The repurchase of our common stock. Our Board of Directors has authorized the repurchase of up to $1.928 billion worth of our common stock through multiple authorizations. Through April 30, 2012, we repurchased approximately 276.8 million shares of our common stock at a cost of $1.870 billion and had $58.6 million of authorization remaining for the purchase of our common stock under this program. We spent approximately $36.5 million during the first quarter of 2012 and $39.5 million during the first quarter of 2011 for the repurchase of our common stock. Currently, there is no expiration date for our common stock repurchase program.

•

Dividend payments. Cash dividends paid were $26.5 million or $.15 per share in the first quarter of 2012. There were no cash dividends paid during the first quarter of 2011 since the payment date of the cash dividend declared in December 2010 occurred in 2010.

•

Principal payments of our debt. Principal payments in the first quarter of 2011 include payments of $35.0 million to reduce the outstanding debt associated with our credit facility. We fully repaid the outstanding balance of our credit facility in 2011 and had no debt during the first quarter 2012.

We believe our operating cash flow, available borrowing capacity, and existing cash and cash equivalents should provide adequate funds for ongoing operations; continued investment in new products and equipment; our common stock repurchase program and future dividend payments.

Forward-Looking Information and Risk Factors

The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements. Certain information contained in this discussion is or may be considered forward-looking. Forward-looking statements relate to future operations, strategies, financial results or other developments. Forward-looking statements are based upon estimates and assumptions that involve certain risks and uncertainties, many of which are beyond our control or are subject to change. Although we believe our assumptions are reasonable, they could be inaccurate. Our actual future revenues and income could differ materially from our expected results. We have no obligation to publicly update or revise any forward-looking statements.

Among the risks and uncertainties which may affect our future operations, strategies, financial results or other developments are those risks described in our latest Annual Report on Form 10-K in Part I, Item 1A. These risks include the following:

•

changes in capital markets that may affect our revenues and earnings;

•

product development risk;

•

consolidation within our target markets, including consolidations between banks and other financial institutions;

•

risk of failure by a third-party service provider;

•

the performance of the funds we manage;

•

the affect of extensive governmental regulation;

•

systems and technology risks;

•

data security risks;

•

third party approval of our investment products with advisors affiliated with independent broker-dealers or other networks;

•

operational risks associated with the processing of investment transactions;

•

changes in, or interpretation of, accounting principles or tax rules and regulations;

•

fluctuations in foreign currency exchange rates; and

•

retention of senior management personnel.

SEI is a savings and loan holding company subject to supervision and regulation by the Federal Reserve. SEI is not subject to specific statutory capital requirements. However, SEI is required to maintain capital that is sufficient to support the holding

Page 32 of 37

company and its subsidiaries’ business activities, and the risks inherent in those activities. To manage capital adequacy, SEI currently utilizes a target Tier 1 Leverage Ratio as defined by the Board of Governors of the Federal Reserve System.

Our principal, regulated wholly-owned subsidiaries are SEI Investments Distribution Co., or SIDCO, SEI Investments Management Corporation, or SIMC, SEI Private Trust Company, or SPTC, SEI Trust Company, or STC, and SEI Investments (Europe) Limited, or SIEL. SIDCO is a broker-dealer registered with the SEC under the Securities and Exchange Act of 1934 and is a member of the Financial Industry Regulatory Authority, Inc. (FINRA). SIMC is an investment advisor registered with the SEC under the Investment Advisers Act of 1940. SPTC is a limited purpose federal thrift chartered and regulated by the Office of the Comptroller of the Currency. STC is a Pennsylvania trust company, regulated by the Pennsylvania Department of Banking. SIEL is an investment manager and financial institution subject to regulation by the Financial Services Authority of the United Kingdom. In addition, various SEI subsidiaries are subject to the jurisdiction of regulatory authorities in Canada, the Republic of Ireland and other foreign countries. The Company has a minority ownership interest in LSV, which is also an investment advisor registered with the SEC.

The Company, its regulated subsidiaries, their regulated services and solutions and their customers are all subject to extensive legislation, regulation and supervision that recently has been subject to, and continues to experience, significant change and increased regulatory activity. These changes and regulatory activities could have a material adverse affect on us and our clients.

The various governmental agencies and self-regulatory authorities that regulate or supervise the Company and various of its subsidiaries have broad administrative powers. In the event of a failure to comply with laws, regulations and requirements of these agencies and authorities, the possible sanctions that may be imposed include the suspension of individual employees, limitations on our ability to engage in business for specified periods of time, the revocation of applicable registration as a broker-dealer, investment advisor or other regulated entity, and, as the case may be, censures and fines. Additionally, certain securities and banking laws applicable to us and our subsidiaries provide for certain private rights of action that could give rise to civil litigation. Any litigation could have significant financial and non-financial consequences including monetary judgments and the requirement to take action or limit activities that could ultimately affect our business.

Governmental scrutiny from regulators, legislative bodies and law enforcement agencies with respect to matters relating to our regulated subsidiaries and their activities, services and solutions, our business practices, our past actions and other matters has increased dramatically in the past several years. Responding to these examinations, investigations, actions and lawsuits, regardless of the ultimate outcome of the proceeding, is time consuming and expensive and can divert the time and effort of our senior management from our business. Penalties and fines sought by regulatory authorities have increased substantially over the last several years, and certain regulators have been more likely in recent years to commence enforcement actions or to advance or support legislation targeted at the financial services industry. Governmental scrutiny and legal and enforcement proceedings can also have a negative impact on our reputation and on the morale and performance of our employees, which could adversely affect our businesses and results of operations.

We are subject to the USA PATRIOT Act of 2001, which contains anti-money laundering and financial transparency laws and requires implementation of regulations applicable to financial services companies, including standards for verifying client identification and monitoring client transactions and detecting and reporting suspicious activities. Anti-money laundering laws outside the United States contain similar requirements.

We offer investment and banking solutions that also are subject to regulation by the federal and state securities and banking authorities, as well as foreign regulatory authorities, where applicable. Existing or future regulations that affect these solutions could lead to a reduction in sales of these solutions or require modifications of these solutions.

Compliance with existing and future regulations and responding to and complying with recent increased regulatory activity affecting broker-dealers, investment advisors, investment companies, financial institutions and their service providers could have a significant impact on us. We periodically undergo regulatory examinations and respond to regulatory inquiries and document requests. In addition, recent legislative activity in the United States (including the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and attendant rule making activities) and in other jurisdictions (including the European Union and the United Kingdom) have made and continue to make, extensive changes to the laws regulating financial services firms. As a result of these examinations, inquiries and requests, as a result of increased civil litigation activity, and as a result of these new laws and regulations, we engage legal counsel, review our compliance procedures, solution and service offerings,

Page 33 of 37

and business operations, and make changes as we deem necessary. These additional activities and required changes may result in increased expense or may reduce revenues.

Our bank clients are subject to supervision by federal and state banking authorities concerning the manner in which such clients purchase and receive our products and services. Our plan sponsor clients and our subsidiaries providing services to those clients are subject to supervision by the Department of Labor and compliance with employee benefit regulations. Investment advisor and broker-dealer clients are regulated by the SEC, state securities authorities, or FINRA. Existing or future regulations applicable to our clients may affect our clients’ purchase of our products and services.

In addition, see the discussion of governmental regulations in Item 1A “Risk Factors” in our latest Annual Report on Form 10-K for a description of the risks that proposed regulatory changes may present for our business.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Information regarding our market risk exposures appears in Part II – Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2011. There have been no material changes in our market risk exposures from those disclosed in our Annual Report on Form 10-K for 2011.

Item 4.

Controls and Procedures.

(a) Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report are effective in ensuring that information required to be disclosed by us in reports filed under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Act is accumulated and communicated to the issuer’s management including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. A controls system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the controls systems are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

(b) Change in Internal Control over Financial Reporting

No change in our internal control over financial reporting occurred during the quarter ended March 31, 2012 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II.

OTHER INFORMATION

Item 1.

Legal Proceedings.

SEI has been named in six lawsuits filed in Louisiana. Five lawsuits were filed in the 19th Judicial District Court for the Parish of East Baton Rouge, State of Louisiana. One of the five actions purports to set forth claims on behalf of a class and also names SPTC as a defendant. Two of the other actions also name SPTC as a defendant. All five actions name various defendants in addition to SEI, and, in all five actions, the plaintiffs purport to bring a cause of action under the Louisiana Securities Act. The putative class action originally included a claim against SEI and SPTC for an alleged violation of the Louisiana Unfair Trade Practices Act. Two of the other five actions include claims for violations of the Louisiana Racketeering Act and possibly conspiracy. In addition, another group of plaintiffs have filed a lawsuit in the 23rd Judicial District Court for the Parish of Ascension, State of Louisiana, against SEI and SPTC and other defendants asserting claims of negligence, breach of contract, breach of fiduciary duty, violations of the uniform fiduciaries law, negligent misrepresentation, detrimental reliance, violations of the Louisiana Securities Act and Louisiana Racketeering Act and conspiracy. The underlying allegations in all the actions are purportedly related to the role of SPTC in providing back-office services to Stanford Trust Company. The petitions allege that SEI and SPTC aided and abetted or otherwise participated in the sale of “certificates of deposit” issued by Stanford International Bank. Two of the five actions filed in East Baton Rouge have been removed to federal court, and plaintiffs’ motions to remand are pending. These two cases have been transferred by the Judicial Panel on Multidistrict Litigation to United States District Court for the Northern District of Texas. On August 31, 2011, the United States District Court for the Northern District of Texas issued an order and judgment that the causes of action alleged against SEI and SPTC in the two remanded actions were preempted by federal law and the Court dismissed these cases with prejudice. The Court of Appeals for the Fifth Circuit granted an expedited appeal of the United States District Court’s order and judgment. The appeal was briefed, and oral argument was held on February 7, 2012. On March 19, 2012, a panel of the Court of Appeals for the Fifth Circuit reversed the decision of the United States District Court and remanded the actions for further proceedings. On April 2, 2012, SEI filed with the United States Court of Appeals for the Fifth Circuit a petition for rehearing en banc of the panel’s opinion. On April 19, 2012, the Fifth Circuit Court of Appeals denied the petition for rehearing.

action; plaintiffs filed a motion for class certification; and SEI and SPTC also filed a motion for summary judgment against certain named plaintiffs which the Court stated will not be set for hearing until after the hearing on the class certification motion. Following the decision by the United States District Court for the Northern District of Texas, the Court in the East Baton Rouge action issued an order staying the proceedings in the East Baton Rouge class action pending the outcome of the appeal of the order and judgment of the United States District Court for the Northern District of Texas. Following the panel opinion of the Court of Appeals on March 19, 2012, the Court in the East Baton Rouge action scheduled a hearing on class certification for September 20, 2012. While the outcome of this litigation is uncertain given its early phase, SEI and SPTC believe that they have valid defenses to plaintiffs’ claims and intend to defend the lawsuits vigorously.
