1.                 Background

As used in this quarterly report on Form 10-Q, references to the “Company,” “Alexandria,” “we,” “our,” and “us” refer to Alexandria Real Estate Equities, Inc. and its subsidiaries.

Alexandria Real Estate Equities, Inc. (NYSE: ARE), a self-administered and self-managed real estate investment trust (“REIT”), is the largest and leading investment-grade REIT focused principally on owning, operating, developing, redeveloping, and acquiring high-quality, sustainable real estate for the broad and diverse life science industry.  Founded in 1994, Alexandria was the first REIT to identify and pursue the laboratory niche and has since had the first-mover advantage in the core life science cluster locations, including Greater Boston, San Francisco Bay, San Diego, New York City, Seattle, Suburban Washington, D.C., and Research Triangle Park. Alexandria’s high-credit client tenants span the life science industry, including renowned academic and medical institutions, multinational pharmaceutical companies, public and private biotechnology entities, United States government research agencies, medical device companies, industrial biotech companies, venture capital firms, and life science product and service companies. As the recognized real estate partner of the life science industry, Alexandria has a superior track record in driving client tenant productivity and innovation through its best-in-class laboratory and office space, collaborative locations adjacent to leading academic and medical institutions, unparalleled life science real estate expertise and services, and longstanding and expansive network in the life science community, which we believe result in higher occupancy levels, longer lease terms, higher rental income, higher returns, and greater long-term asset value. For additional information on Alexandria Real Estate Equities, Inc., please visit www.are.com.

2.                 Basis of presentation

We have prepared the accompanying interim condensed consolidated financial statements in accordance with United States generally accepted accounting principles (“GAAP”) and in conformity with the rules and regulations of the Securities and Exchange Commission (“SEC”).  In our opinion, the interim condensed consolidated financial statements presented herein reflect all adjustments that are necessary to fairly present the interim condensed consolidated financial statements.  The results of operations for the interim period are not necessarily indicative of the results that may be expected for the year ending December 31, 2012.  These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in our annual report on Form 10-K for the year ended December 31, 2011.

The accompanying condensed consolidated financial statements include the accounts of Alexandria Real Estate Equities, Inc. and its subsidiaries.  All significant intercompany balances and transactions have been eliminated.

We hold interests, together with certain third parties, in companies that we consolidate in our financial statements.  We consolidate the companies because we exercise significant control over major decisions of these entities, such as investing activity and changes in financing.

Use of estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, equity, the disclosure of contingent assets and liabilities as of the date of the condensed consolidated financial statements, and the amounts of revenues and expenses during the reporting period.  Actual results could materially differ from those estimates.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation.

Investments in real estate, net, and discontinued operations

We recognize assets acquired (including the intangible value of above or below market leases, acquired in-place leases, client tenant relationships, and other intangible assets or liabilities), liabilities assumed, and any noncontrolling interest in an acquired entity at their fair value as of the acquisition date.  If there is a bargain fixed rate renewal option for the period beyond the non-cancelable lease term, we evaluate factors such as the business conditions in the industry in which the lessee operates, the economic conditions in the area in which the property is located, and the ability of the lessee to sublease the property during the renewal term, in order to determine the likelihood that the lessee will renew.  When we determine there is reasonable assurance such bargain purchase option will be exercised, we consider its impact in determining the intangible value of such lease and its related amortization period.  The value of tangible assets acquired is based upon our estimation of value on an “as if vacant” basis.  The value of acquired in-place leases includes the estimated carrying costs during the hypothetical lease-up period and other costs that would have been incurred to execute similar leases, considering market conditions at the acquisition date of the acquired in-place lease.  We assess the fair value of tangible and intangible assets based on numerous factors, including estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information.  Estimates of future cash flows are based on a number of factors, including the historical operating results, known trends, and market/economic conditions that may affect the property.  We also recognize the fair values of assets acquired, the liabilities assumed, and any noncontrolling interest in acquisitions of less than a 100% interest when the acquisition constitutes a change in control of the acquired entity.  Acquisition-related costs and restructuring costs are expensed as incurred.

The values allocated to land improvements, tenant improvements, equipment, buildings, and building improvements are depreciated on a straight-line basis using an estimated life of 20 years for land improvements, the respective lease term for tenant improvements, the estimated useful life for equipment, and the shorter of the term of the respective ground lease and up to 40 years for buildings and building improvements.  The values of acquired above and below market leases are amortized over the lives of the related leases and recorded as either an increase (for below market leases) or a decrease (for above market leases) to rental income.  The values of acquired in-place leases are included in other assets in the accompanying condensed consolidated balance sheets, and amortized over the remaining terms of the related leases.

We are required to capitalize direct construction and development costs, including predevelopment costs, interest, property taxes, insurance, and other costs directly related and essential to the acquisition, development, redevelopment, or construction of a project.  Capitalization of development, redevelopment, and construction costs is required while activities are ongoing to prepare an asset for its intended use.  Fluctuations in our development, redevelopment, and construction activities could result in significant changes to total expenses and net income.  Costs incurred after a project is substantially complete and ready for its intended use are expensed as incurred.  Should development, redevelopment, or construction activity cease, interest, property taxes, insurance, and certain other costs would no longer be eligible for capitalization and would be expensed as incurred. Expenditures for repairs and maintenance are expensed as incurred.

A property is classified as “held for sale” when all of the following criteria for a plan of sale have been met: (1) management, having the authority to approve the action, commits to a plan to sell the property; (2) the property is available for immediate sale in its present condition, subject only to terms that are usual and customary; (3) an active program to locate a buyer and other actions required to complete the plan to sell have been initiated; (4) the sale of the property is probable and is expected to be completed within one year; (5) the property is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (6) actions necessary to complete the plan of sale indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.  When all of these criteria have been met, the property is classified as “held for sale”; its operations, including any interest expense directly attributable to it, are classified as discontinued operations in our condensed consolidated statements of income; and amounts for all prior periods presented are reclassified from continuing operations to discontinued operations.  Depreciation of assets ceases upon designation of a property as “held for sale.”

Long-lived assets to be held and used, including our rental properties, land held for future development, construction in progress, and intangibles, are individually evaluated for impairment when conditions exist that may indicate that the carrying amount of a long-lived asset may not be recoverable.  The carrying amount of a long-lived asset to be held and used is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset.  Impairment indicators for long-lived assets to be held and used, including our rental properties, land held for future development, and construction in progress, are assessed by project and include, but are not limited to, significant fluctuations in estimated net operating income, occupancy changes, construction costs, estimated completion dates, rental rates, and other market factors.  We assess the expected undiscounted cash flows based upon numerous factors, including, but not limited to, construction costs, available market information, historical operating results, known trends, market/economic conditions that may affect the property, and our assumptions about the use of the asset, including, if necessary, a probability-weighted approach if multiple outcomes are under consideration.  Upon

determination that an impairment has occurred, a write-down is recorded to reduce the carrying amount to its estimated fair value.  If an impairment loss is not required to be recorded, the recognition of depreciation is adjusted prospectively, as necessary, to reduce the carrying amount of the real estate to its estimated disposition value over the remaining period that the real estate is expected to be held and used.  We may adjust depreciation of properties that are expected to be disposed of or redeveloped prior to the end of their useful lives.

We use a “held for sale” impairment model for our properties classified as “held for sale.”  The “held for sale” impairment model is different from the held and used impairment model.  Under the “held for sale” impairment model, an impairment loss is recognized if the carrying amount of the long-lived asset classified as “held for sale” exceeds its fair value less cost to sell.

Investments

We hold equity investments in certain publicly traded companies and privately held entities primarily involved in the life science industry.  All of our investments in actively traded public companies are considered “available for sale” and are recorded at fair value.  Fair value has been determined based upon the closing price as of each balance sheet date, with unrealized gains and losses shown as a separate component of comprehensive income.  The classification of each investment is determined at the time each investment is made, and such determination is reevaluated at each balance sheet date.  The cost of each investment sold is determined by the specific identification method, with net realized gains or losses included in other income.  Investments in privately held entities are generally accounted for under the cost method when our interest in the entity is so minor that we have virtually no influence over the entity’s operating and financial policies.  Additionally, we limit our ownership percentage in the voting stock of each individual entity to less than 10%.  As of September 30, 2012, and December 31, 2011, our ownership percentage in the voting stock of each individual entity was less than 10%.

Individual investments are evaluated for impairment when changes in conditions may indicate an impairment exists.  The factors that we consider in making these assessments include, but are not limited to, market prices, market conditions, available financing, prospects for favorable or unfavorable clinical trial results, new product initiatives, and new collaborative agreements.  If there are no identified events or changes in circumstances that would have an adverse effect on our cost method investments, we do not estimate the investment’s fair value.  For all of our investments, if a decline in the fair value of an investment below the carrying value is determined to be other than temporary, such investment is written down to its estimated fair value with a non-cash charge to current earnings.  For a description of the methodology we use to determine the fair value of privately held entities, refer to Note 7, Fair Value of Financial Instruments.

Income taxes

We are organized and qualify as a REIT pursuant to the Internal Revenue Code of 1986, as amended (the “Code”).  Under the Code, a REIT that distributes at least 90% of its REIT taxable income as a dividend to its shareholders each year and that meets certain other conditions is not subject to federal income taxes, but is subject to certain state and local taxes.  We generally distribute 100% or more of our taxable income.  Therefore, no provision for federal income taxes is required.  We file tax returns, including returns for our subsidiaries, with federal, state, and local jurisdictions, including jurisdictions located in the United States, Canada, India, China, and other international locations.  Our tax returns are subject to examination in various jurisdictions for the calendar years 2007 through 2011.

We recognize tax benefits of uncertain tax positions only if it is more likely than not that the tax position will be sustained, based solely on its technical merits, with the taxing authority having full knowledge of all relevant information.  The measurement of a tax benefit for an uncertain tax position that meets the “more likely than not” threshold is based on a cumulative probability model under which the largest amount of tax benefit recognized is the amount with a greater than 50% likelihood of being realized upon ultimate settlement with the taxing authority having full knowledge of all the relevant information.  As of September 30, 2012, there were no unrecognized tax benefits.  We do not anticipate a significant change to the total amount of unrecognized tax benefits within the next 12 months.

Interest expense and penalties, if any, would be recognized in the first period the interest or penalty would begin accruing, according to the provisions of the relevant tax law at the applicable statutory rate of interest.  We did not incur any tax-related interest expense or penalties for the three and nine months ended September 30, 2012 and 2011.

Interest income

Interest income was approximately $1.0 million and $0.2 million during the three months ended September 30, 2012 and 2011, respectively.  Interest income was approximately $2.5 million and $0.3 million during the nine months ended September 30, 2012 and 2011, respectively.  Interest income is classified in other income in the accompanying condensed consolidated statements of income.

Recognition of rental income and tenant recoveries

Rental income from leases with scheduled rent increases, free rent, incentives, and other rent adjustments is recognized on a straight-line basis over the respective lease terms. We include amounts currently recognized as income, and expected to be received in later years, as an asset in deferred rent in the accompanying condensed consolidated balance sheets. Amounts received currently, but recognized as income in future years, are included in accounts payable, accrued expenses, and tenant security deposits in the accompanying condensed consolidated balance sheets. We commence recognition of rental income at the date the property is ready for its intended use and the client tenant takes possession of or controls the physical use of the property.

Tenant recoveries related to reimbursement of real estate taxes, insurance, utilities, repairs and maintenance, and other operating expenses are recognized as revenue in the period in which the applicable expenses are incurred.

We maintain an allowance for estimated losses that may result from the inability of our client tenants to make payments required under the terms of the lease and for tenant recoveries due. If a client tenant fails to make contractual payments beyond any allowance, we may recognize additional bad debt expense in future periods equal to the amount of unpaid rent and unrealized deferred rent.  As of September 30, 2012, and December 31, 2011, we had no allowance for estimated losses.

As of September 30, 2012, approximately 94% of our leases (on a rentable square footage basis) were triple net leases, requiring client tenants to pay substantially all real estate taxes, insurance, utilities, common area expenses, and other operating expenses (including increases thereto) in addition to base rent.  Approximately 96% of our leases (on a rentable square footage basis) contained effective annual rent escalations that were either fixed or based on a consumer price index or another index.  Additionally, approximately 91% of our leases (on a rentable square footage basis) provided for the recapture of certain capital expenditures.

Impact of recently issued accounting standards

In May 2011, the FASB issued an Accounting Standards Update (“ASU”) to substantially converge the guidance in GAAP and International Financial Reporting Standards (“IFRS”) on fair value measurements and disclosures.  The ASU changes several aspects of the fair value measurement guidance in FASB Accounting Standards Codification 820, Fair Value Measurement, including (1) the application of the concepts of highest and best use and valuation premise; (2) the introduction of an option to measure groups of offsetting assets and liabilities on a net basis; (3) the incorporation of certain premiums and discounts in fair value measurements; and (4) the measurement of the fair value of certain instruments classified in stockholders’ equity.  In addition, the ASU includes several new fair value disclosure requirements, such as information about valuation techniques and significant unobservable inputs used in fair value measurements and a narrative description of the fair value measurements’ sensitivity to changes in significant unobservable inputs.  The ASU is effective for public companies during the interim and annual periods, beginning after December 15, 2011.  We adopted the ASU as of January 1, 2012. The adoption of the ASU did not impact our condensed consolidated financial statements or related disclosures.

In June 2011, the FASB issued an ASU to make presentation of items within other comprehensive income (“OCI”) more prominent.  Entities are required to present items of net income, items of OCI, and total comprehensive income either in a single continuous statement or in two separate but consecutive statements.  There no longer exists the option to present OCI in the statement of changes in stockholders’ equity.  In December 2011, the FASB decided to defer the requirement that companies present reclassification adjustments for each component of accumulated other comprehensive income (“AOCI”) in both net income and OCI on the face of the financial statements.  Reclassifications out of AOCI will be either presented on the face of the financial statement in which OCI is presented or disclosed in the notes to the financial statements.  This deferral does not change the requirement to present items of net income, items of OCI, and total comprehensive income in either one continuous statement or two separate consecutive statements.  The ASU is effective for public companies during the interim and annual periods, beginning after December 15, 2011.  We adopted this guidance as of January 1, 2012, and have presented the condensed consolidated statements of comprehensive income separately from the condensed consolidated statements of income.

Our investments in real estate, net, consisted of the following as of September 30, 2012, and December 31, 2011 (in thousands):

Land held for future development represents real estate we plan to develop in the future but on which, as of each period presented, no construction or preconstruction activities were ongoing.  As a result, interest, property taxes, insurance, and other costs are expensed as incurred.  As of September 30, 2012, and December 31, 2011, we held land in North America supporting an aggregate of 5.5 million and 4.8 million rentable square feet of future ground-up development, respectively.  Additionally, as of September 30, 2012, and December 31, 2011, we held land undergoing preconstruction activities in North America totaling 2.4 million and 2.7 million rentable square feet, respectively.  Land undergoing preconstruction activities (consisting of Building Information Modeling [BIM or 3-D virtual modeling], design development and construction drawings, sustainability and energy optimization review, budgeting, planning for future site and infrastructure work, and other activities prior to commencement of vertical construction of aboveground shell and core improvements) that are also classified as construction in progress.  Our objective with preconstruction is to reduce the time it takes to deliver projects to prospective client tenants.  Project costs are capitalized as a cost of the project during periods when activities necessary to prepare an asset for its intended use are in progress.  We generally will not commence ground-up development of any parcels undergoing preconstruction activities without first securing pre-leasing for such space.  If vertical aboveground construction is not initiated at completion of preconstruction activities, the land parcel will be classified as land held for future development.  The two largest projects included in land undergoing preconstruction consist of our 1.6 million developable square feet at Alexandria Center™ at Kendall Square in East Cambridge, Massachusetts, and our 419,806 developable square feet site for the West Tower of the Alexandria Center™ for Life Science – New York City.

Real estate asset sales

The following table summarizes our real estate asset disposition activities for the nine months ended September 30, 2012 (dollars in thousands, except per square foot amounts):

(1)         Represents contractual sales price for assets sold or contractual/estimated sale price for sales in process.

(2)         Properties sold to residential developers.

(3)         In March 2012, we sold one-half of our 55% interest in a land parcel supporting a project with 414,000 rentable square feet for approximately $31.4 million, or approximately $275 per rentable square foot.

(4)         Sales price reflects the near-term lease expiration of a client tenant occupying 38,513 rentable square feet, or 18% of the total rentable square feet, on the date of sale.  In connection with the sale, we received an interest-only secured note receivable for $6.1 million due in 2018.

(5)         Properties were sold to client tenants.

Impairment of real estate assets held for sale

In September 2012, four properties aggregating 504,130 rentable square feet met the classification requirements for held for sale.  During the three months ended September 30, 2012, we recorded impairment charges aggregating approximately $9.8 million to reduce the aggregate carrying value of the properties to the estimated sales price less costs to sell. We used the preliminary sales price estimates based on offers from prospective buyers as a significant observable input (level 2) within the valuation hierarchy to determine the estimated fair value of these assets.

Sale of land parcel

In March 2012, we contributed our 55% ownership interest in a land parcel supporting a future building with 414,000 rentable square feet in the Longwood Medical Area of the Greater Boston market to a newly formed joint venture (the “Restated JV”) with National Development and Charles River Realty Investors, and admitted as a 50% member Clarion Partners, LLC, resulting in a reduction of our ownership interest from 55% to 27.5%.  The transfer of one-half of our 55% ownership interest in this real estate venture to Clarion Partners, LLC, was accounted for as an in-substance partial sale of an interest in the underlying real estate.  In connection with the sale of one-half of our 55% ownership interest in the land parcel, we received a special distribution of approximately $22.3 million, which included the recognition of a $1.9 million gain on sale of land and approximately $5.4 million from our share of loan refinancing proceeds.  The land parcel we sold in March 2012 did not meet the criteria for discontinued operations since the parcel did not have any significant operations prior to disposition. Pursuant to the presentation and disclosure literature on gains/losses on sales or disposals by REITs required by the Securities and Exchange Commission (“SEC”), gains or losses on sales or disposals by a REIT that do not qualify as discontinued operations are classified below (loss) income from discontinued operations in the income statement.  Accordingly, we classified the $1.9 million gain on sale of land below (loss) income from discontinued operations, net, in the condensed consolidated statements of income.  Our 27.5% share of the land was sold at approximately $31 million (including closing costs), or approximately $275 per rentable square foot.  Upon formation of the Restated JV, the existing $38.4 million secured loan was refinanced with a seven-year (including two one-year extension options) non-recourse $213 million secured construction loan with initial loan proceeds of $50 million.  As of September 30, 2012, the outstanding balance on the construction loan was $56.4 million.  We do not expect our share of capital contributions through the completion of the project to exceed the approximate $22.3 million in net proceeds received in this transaction.  Construction of this $350 million project commenced in April 2012.  The initial occupancy date for this project is expected to be in the fourth quarter of 2014.  The project is 37% pre-leased to Dana-Farber Cancer Institute, Inc.  In addition, Dana-Farber Cancer Institute, Inc. has an option to lease an additional two floors approximating 99,000 rentable square feet, or 24% of the total rentable square feet of the project.  In addition to our economic share of the joint venture, we also expect to earn development and other fees of approximately $3.5 million through 2015, and recurring annual property management fees thereafter, from this project.

We do not qualify as the primary beneficiary of the Restated JV since we do not have the power to direct the activities of the entity that most significantly impacts its economic performance.  The decisions that most significantly impact the entity’s economic performance require both our consent and that of our partners for all major operating, investing, and financing decisions, as well as decisions involving major expenditures.  As of September 30, 2012, and December 31, 2011, our investment in the unconsolidated real estate entity of approximately $27.0 million and $42.3 million, respectively, was classified as an investment in real estate in the accompanying condensed consolidated balance sheets.

Our investment in the unconsolidated real estate entity is adjusted for additional contributions and distributions, the proportionate share of the net earnings or losses, and other comprehensive income or loss.  Distributions, profits, and losses related to this entity are allocated in accordance with the operating agreement.  When circumstances indicate that there may have been a reduction in value of an equity investment, we evaluate the equity investment and any advances made for impairment by estimating our ability to recover our investment from future expected cash flows.  If we determine the loss in value is other than temporary, we recognize an impairment charge to reflect the equity investment and any advances made at fair value.

4.               Investments

We hold equity investments in certain publicly traded companies and privately held entities primarily involved in the life science industry.  Investments in “available for sale” securities with gross unrealized losses as of September 30, 2012, had been in a continuous unrealized loss position for less than 12 months.  We have the ability and intent to hold these investments for a reasonable period of time sufficient for the recovery of our investment.  We believe that these unrealized losses are temporary, and accordingly we have not recognized an other-than-temporary impairment related to “available for sale” securities as of September 30, 2012.  As of September 30, 2012, and December 31, 2011, there were no unrealized losses in our investments in privately held entities.
