Alexandria Real Estate Equities, Inc. Notes to Condensed Consolidated Financial Statements (Unaudited)

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 investment-grade real estate investment trust (“REIT”), is the largest and leading REIT focused principally on owning, operating, developing, redeveloping, and acquiring high-quality, sustainable real estate for the broad and diverse life science industry.  Alexandria’s client tenants span the life science industry, including renowned academic and medical institutions, multinational pharmaceutical companies, public and private biotechnology entities, United States (“U.S.”) government research agencies, medical device companies, industrial biotech companies, venture capital firms, and life science product and service companies.  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 U.S. 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, 2013.  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, 2012.

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 by these entities, such as investment 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, and 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 that 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 recognized 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 classified 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 project 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”; if (1) the operations and cash flows of the property have been or will be eliminated from the ongoing operations, and (2) we will not have any significant continuing involvement in the operations of the property after the sale, then 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.”

Impairment of long-lived assets

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 or triggering events 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 significant fluctuations in estimated net operating income, occupancy changes, significant near-term lease expirations, current and historical operating and/or cash flow losses, 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, current and historical operating results, known trends, current 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 recognized to reduce the carrying amount to its estimated fair value.  If an impairment loss is not required to be recognized, 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.  Because of these two different models, it is possible for a long-lived asset previously classified as held and used to require the recognition of an impairment charge upon classification as “held for sale.”

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 reflected in the accompanying condensed consolidated balance sheets 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 classified in other income in the accompanying condensed consolidated statements of 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.  Certain investments in privately held entities are accounted for under the equity method when our interest in the entity is not deemed so minor that we have virtually no influence over the entity’s operating and financial policies.  Under the equity method of accounting, we recognize our investment initially at cost and adjust the carrying amount of the investment to recognize our share of the earnings or losses of the investee subsequent to the date of our investment.  Additionally, we limit our ownership percentage in the voting stock of each individual entity to less than 10%.  As of March 31, 2013, and December 31, 2012, 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 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.

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 100% 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 could be subject to certain state and local taxes.  We have distributed 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 U.S., Canada, India, China, and other international locations.  Our tax returns are subject to examination in various jurisdictions for the calendar years 2008 through 2012.

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 March 31, 2013, 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 during which 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 material tax-related interest expense or penalties for the three months ended March 31, 2013 and 2012.

Interest income

Interest income was approximately $1.3 million and $0.6 million during the three months ended March 31, 2013 and 2012, 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 is recognized on a straight-line basis over the respective lease terms.  We classify 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 classified 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 during which the applicable expenses are incurred.

Tenant receivables consist primarily of amounts due for contractual lease payments, reimbursements of common area maintenance expenses, property taxes, and other expenses recoverable from client tenants.  Tenant receivables are expected to be collected within one year.  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 uncollectible rent and deferred rent receivables arising from the straight-lining of rent.  As of March 31, 2013, and December 31, 2012, we had no allowance for estimated losses.

As of March 31, 2013, 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 92% of our leases (on a rentable square footage basis) provided for the recapture of certain capital expenditures.

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 March 31, 2013, and December 31, 2012, we held land in North America supporting an aggregate of 3.8 million and 4.7 million rentable square feet of future ground-up development, respectively.  Additionally, as of March 31, 2013, and December 31, 2012, we held land undergoing preconstruction activities in North America totaling 1.9 million and 2.9 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) is 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 largest project primarily included in land undergoing preconstruction consists of our 1.2 million developable square feet at Alexandria Center™ at Kendall Square in East Cambridge, Massachusetts.

Real estate asset sales

During the three months ended March 31, 2013, we sold six properties in three separate transactions for aggregate consideration of approximately $124.3 million, at a net loss of approximately $0.3 million, which included an aggregate gain of approximately $0.1 million on the sale of two properties in the Suburban Washington, D.C. market, an aggregate loss of approximately $0.4 million on sale of three properties in the Greater Boston market, and no gain or loss on the sale of a property in the Seattle market.

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 March 31, 2013, 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 other-than-temporary impairment related to “available for sale” securities as of March 31, 2013.  As of March 31, 2013, and December 31, 2012, there were no unrealized losses in our investments in privately held entities.

4.60% Unsecured senior notes payable

In February 2012, we completed a $550.0 million public offering of our unsecured senior notes payable at a stated interest rate of 4.60%.  The unsecured senior notes payable were priced at 99.915% of the principal amount with a yield to maturity of 4.61% and are due April 1, 2022.  The unsecured senior notes payable are unsecured obligations of the Company and are fully and unconditionally guaranteed by Alexandria Real Estate Equities, L.P., a 100% owned subsidiary of the Company.  The unsecured senior notes payable rank equally in right of payment with all other senior unsecured indebtedness.  However, the unsecured senior notes payable are effectively subordinated to existing and future mortgages and other secured indebtedness (to the extent of the value of the collateral securing such indebtedness) and to all existing and future preferred equity and liabilities, whether secured or unsecured, of the Company’s subsidiaries, other than Alexandria Real Estate Equities, L.P.  We used the net proceeds of this offering to prepay the outstanding principal balance of $250.0 million on our unsecured senior bank term loan (“2012 Unsecured Senior Bank Term Loan”) and to reduce the outstanding borrowings on our unsecured senior line of credit.

5.     Secured and unsecured senior debt (continued)

The requirements of the key financial covenants under our unsecured senior notes payable as of March 31, 2013, are as follows:

Covenant Ratios (1) Requirement
Total Debt to Total Assets Less than or equal to 60%
Consolidated EBITDA to Interest Expense Greater than or equal to 1.5x
Unencumbered Total Asset Value to Unsecured Debt Greater than or equal to 150%
Secured Debt to Total Assets Less than or equal to 40%
(1) For a definition of the ratios used in the table above, refer to the indenture dated February 29, 2012 (“Indenture”), which governs the unsecured senior notes payable, which was filed as an exhibit to our Current Report on Form 8-K filed with the SEC on February 29, 2012.
--- ---

In addition, the terms of the Indenture, among other things, limit the ability of the Company, Alexandria Real Estate Equities, L.P., and the Company’s other subsidiaries to (1) consummate a merger, or consolidate or sell all or substantially all of the Company’s assets, and (2) incur certain secured or unsecured indebtedness.

Unsecured senior line of credit and unsecured senior bank term loans

In April 2012, we amended our $1.5 billion unsecured senior line of credit with Merrill Lynch, Pierce, Fenner & Smith Incorporated, J.P. Morgan Securities Inc., and Citigroup Global Markets Inc. as joint lead arrangers, and certain lenders, to extend the maturity date of our unsecured senior line of credit, provide an accordion option for up to an additional $500.0 million, and reduce the interest rate for outstanding borrowings.  The maturity date of the unsecured senior line of credit was extended to April 2017, assuming we exercise our sole right to extend the maturity date twice by an additional six months after each exercise.  Borrowings under the unsecured senior line of credit bear interest at LIBOR or the base rate specified in the amended unsecured senior line of credit and unsecured senior bank term loan agreements, plus in either case a specified margin (the “Applicable Margin”).  The Applicable Margin for LIBOR borrowings under the unsecured senior line of credit was set at 1.20%, down from the 2.40% in effect immediately prior to the modification.  In addition to the Applicable Margin, our unsecured senior line of credit is subject to an annual facility fee of 0.25% based on the aggregate commitments outstanding.  In connection with the modification of our unsecured senior line of credit in April 2012, we recognized a loss on early extinguishment of debt of approximately $1.6 million related to the write-off of a portion of unamortized loan fees.

In April 2012, we also amended our 2016 unsecured senior bank term loan (“2016 Unsecured Senior Bank Term Loan”) and 2017 unsecured senior bank term loan (“2017 Unsecured Senior Bank Term Loan”), conforming the financial covenants contained in our unsecured senior bank term loan agreements to those contained in our amended $1.5 billion unsecured senior line of credit.

In February 2012, we recognized a loss on early extinguishment of debt of approximately $0.6 million related to the write-off of unamortized loan fees as a result of the early repayment of $250.0 million of our 2012 Unsecured Senior Bank Term Loan.  The requirements of the key financial covenants under our unsecured senior line of credit and unsecured senior bank term loans as of March 31, 2013, are as follows:

Covenant Ratios (1) Requirement
Leverage Ratio Less than or equal to 60.0%
Fixed Charge Coverage Ratio Greater than or equal to 1.50x
Secured Debt Ratio Less than or equal to 40.0%
Unsecured Leverage Ratio Less than or equal to 60.0%
Unsecured Interest Coverage Ratio Greater than or equal to 1.75x
(1) For a definition of the ratios used in the table above, refer to the amended unsecured senior line of credit and unsecured senior bank term loan agreements, dated April 30, 2012, which were filed as exhibits to our Quarterly Report on Form 10-Q filed with the SEC on August 8, 2012.

6.      Interest rate swap agreements

During the three months ended March 31, 2013 and 2012, our interest rate swap agreements were used primarily to hedge the variable cash flows associated with certain of our existing LIBOR-based variable rate debt, including our unsecured senior line of credit and unsecured senior bank term loans.  The ineffective portion of the change in fair value of our interest rate swap agreements is required to be recognized directly in earnings.  During the three months ended March 31, 2013 and 2012, our interest rate swap agreements were 100% effective; because of this, no hedge ineffectiveness was recognized in earnings.  The effective portion of changes in the fair values of our interest rate swap agreements that are designated and that qualify as cash flow hedges is classified in accumulated other comprehensive loss.

The following table reflects the effective portion of the unrealized loss recognized in other comprehensive loss for our interest rate swaps related to the change in fair value for the three months ended March 31, 2013 and 2012 (in thousands):

Unrealized loss recognized in other comprehensive loss related to the effective portion of changes in the fair values of our interest rate swap agreements $ (133 ) $ (4,073 )

Losses are subsequently reclassified into earnings in the period during which the hedged transactions affect earnings.  During the next 12 months, we expect to reclassify approximately $14.0 million accumulated other comprehensive loss to interest expense as an increase to interest expense.  The following table indicates the classification in the condensed consolidated statements of income and the effective portion of the loss reclassified from accumulated other comprehensive income into earnings for our cash flow hedge contracts for the three months ended March 31, 2013 and 2012 (in thousands):

7.      Fair value measurements

Recurring fair value measurements

We are required to disclose fair value information about all financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate fair value.  We measure and disclose the estimated fair value of financial assets and liabilities utilizing a fair value hierarchy that distinguishes between data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions.  This hierarchy consists of three broad levels as follows: (1) quoted prices in active markets for identical assets or liabilities, (2) “significant other observable inputs,” and (3) “significant unobservable inputs.”  “Significant other observable inputs” can include quoted prices for similar assets or liabilities in active markets, as well as inputs that are observable for the asset or liability, such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals.  “Significant unobservable inputs” are typically based on an entity’s own assumptions, since there is little, if any, related market activity.  In instances in which the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level of input that is significant to the fair value measurement in its entirety.  Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.  There were no transfers between the levels in the fair value hierarchy during the three months ended March 31, 2013 and 2012.

The carrying amounts of cash and cash equivalents, restricted cash, tenant receivables, other assets, accounts payable, accrued expenses, and tenant security deposits approximate fair value.  Our “available-for-sale” securities and our interest rate swap agreements, respectively, have been recognized at fair value.  The fair values of our secured notes payable, unsecured senior notes payable, unsecured senior line of credit, unsecured senior bank term loans, and unsecured senior convertible notes were estimated using widely accepted valuation techniques, including discounted cash flow analyses of “significant other observable inputs” such as available market information on discount and borrowing rates with similar terms, maturities, and credit ratings.  Because the valuations of our financial instruments are based on these types of estimates, the actual fair value of our financial instruments may differ materially if our estimates do not prove to be accurate.  Additionally, the use of different market assumptions or estimation methods may have a material effect on the estimated fair value amounts.

As of March 31, 2013, and December 31, 2012, the book and fair values of our marketable securities, interest rate swap agreements, secured notes payable, unsecured senior notes payable, unsecured senior line of credit, and unsecured senior bank term loans were as follows (in thousands):

8. **** Earnings per share

We use income from continuing operations attributable to Alexandria Real Estate Equities, Inc.’s common stockholders as the “control number” in determining whether potential common shares, including potential common shares issuable upon conversion of our 8.00% unsecured senior convertible notes (“8.00% Unsecured Senior Convertible Notes”), are dilutive or antidilutive to earnings per share.  Pursuant to the presentation and disclosure literature on gains or losses on sales or disposals by REITs and earnings per share required by the SEC and the Financial Accounting Standards Board, gains or losses on sales or disposals by a REIT that do not qualify as discontinued operations are classified below income from discontinued operations in the condensed consolidated statements of income and included in the numerator for the computation of earnings per share for income from continuing operations.

The land parcels we sold during the three months ended March 31, 2012 did not meet the criteria for classification as discontinued operations because the land parcels did not have significant operations prior to disposition.  Accordingly, for the three months ended March 31, 2012, we classified approximately $1.9 million as gain on sales of land parcels below income from discontinued operations, net, in the accompanying condensed consolidated statements of income, and included the gain in income from continuing operations attributable to Alexandria Real Estate Equities, Inc.’s common stockholders in the “control number,” or numerator for computation of earnings per share.

We account for unvested restricted stock awards that contain nonforfeitable rights to dividends as participating securities and include these securities in the computation of earnings per share using the two-class method.  Our Series D convertible preferred stock (“Series D Convertible Preferred Stock”) and our 8.00% Unsecured Senior Convertible Notes are not participating securities, and are not included in the computation of earnings per share using the two-class method.  Under the two-class method, we allocate net income after preferred stock dividends, preferred stock redemption charge, and amounts attributable to noncontrolling interests to common stockholders and unvested restricted stock awards based on their respective participation rights to dividends declared (or accumulated) and undistributed earnings.  Diluted earnings per share is computed using the weighted average shares of common stock outstanding determined for the basic earnings per share computation plus the effect of any dilutive securities, including the dilutive effect of stock options using the treasury stock method.

8. **** Earnings per share (continued)

The table below is a reconciliation of the numerators and denominators of the basic and diluted earnings per share computations for the three months ended March 31, 2013 and 2012 (dollars in thousands, except per share amounts):

Continuing operations $ 0.35 $ 0.22
Discontinued operations, net 0.01 0.08

For purposes of calculating diluted earnings per share, we did not assume conversion of our 8.00% Unsecured Senior Convertible Notes for the three months ended March 31, 2013 and 2012, since the impact was antidilutive to earnings per share attributable to Alexandria Real Estate Equities, Inc.’s common stockholders from continuing operations during those periods.

For purposes of calculating diluted earnings per share, we did not assume conversion of our Series D Convertible Preferred Stock for the three months ended March 31, 2013 and 2012, since the impact was antidilutive to earnings per share attributable to Alexandria Real Estate Equities, Inc.’s common stockholders from continuing operations during those periods.

10. **** Stockholders’ equity

“At the market” common stock offering program

In June 2012, we established an “at the market” common stock offering program under which we may sell, from time to time, up to an aggregate of $250.0 million of our common stock through our sales agents, BNY Mellon Capital Markets, LLC and Credit Suisse Securities (USA) LLC, during a three-year period.  Net proceeds from the sales were used to pay down the outstanding balance on our unsecured senior line of credit or other borrowings, and for general corporate purposes.  As of March 31, 2013, approximately $150.0 million of our common stock remained available for issuance under the “at the market” common stock offering program.

Dividends

In March 2013, we declared cash dividends for the first quarter of 2013 on our common stock aggregating approximately $38.2 million, or $0.60 per share.  In March 2013, we also declared cash dividends for the first quarter of 2013 on our Series D Convertible Preferred Stock aggregating approximately $4.4 million, or $0.4375 per share.  Additionally, we declared cash dividends for the third quarter of 2012 on our Series E Preferred Stock aggregating approximately $2.1 million, or $0.403125 per share.  In April 2013, we paid the cash dividends for the third quarter of 2012 on our common stock, Series D Convertible Preferred Stock, and Series E Preferred Stock.

Accumulated other comprehensive loss

10. **** Stockholders’ equity (continued)

The effects on amounts reclassified from accumulated other comprehensive income related to unrealized gain on marketable securities and unrealized gain on interest rate swap agreements are recognized in other income and interest expenses, respectively, in the accompanying condensed consolidated statements of income.

Preferred stock and excess stock authorizations

Our charter authorizes the issuance of up to 100,000,000 shares of preferred stock, of which 15,200,000 shares were issued and outstanding as of March 31, 2013.  In addition, 200,000,000 shares of “excess stock” (as defined in our charter) are authorized, none of which were issued and outstanding as of March 31, 2013.

11. **** Noncontrolling interests

Noncontrolling interests represent the third-party interests in certain entities in which we have a controlling interest.  These entities owned 10 properties and two development parcels as of March 31, 2013, and are included in our condensed consolidated financial statements.  Noncontrolling interests are 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 these entities are allocated in accordance with the respective operating agreements.

Certain of our noncontrolling interests have the right to require us to redeem their ownership interests in the respective entities.  We classify these ownership interests in the entities as redeemable noncontrolling interests outside of total equity in the accompanying condensed consolidated balance sheets.  Redeemable noncontrolling interests are 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 these entities are allocated in accordance with the respective operating agreements.  If the carrying amount of a redeemable noncontrolling interest is less than the maximum redemption value at the balance sheet date, such amount is adjusted to the maximum redemption value.  Subsequent declines in the redemption value are recognized only to the extent that previous increases have been recognized.  As of March 31, 2013, and December 31, 2012, our redeemable noncontrolling interest balances were approximately $14.5 million and $14.6 million, respectively.  Our remaining noncontrolling interests, aggregating approximately $47.1 million and $46.6 million as of March 31, 2013, and December 31, 2012, respectively, do not have rights to require us to purchase their ownership interests and are classified in total equity in the accompanying condensed consolidated balance sheets.

Overview

We are a self-administered and self-managed investment-grade REIT.  We are the largest and leading 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, we are the first REIT to identify and pursue the laboratory niche and have since had the first-mover advantage in the core life science cluster locations including Greater Boston, San Francisco Bay Area, San Diego, New York City, Seattle, Suburban Washington, D.C., and Research Triangle Park.  Our 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.

Our primary business objective is to maximize stockholder value by providing our stockholders with the greatest possible total return and long-term asset value based on a multifaceted platform of internal and external growth.  The key elements to our strategy include our consistent focus on high-quality assets and operations in the top life science cluster locations with our properties located in close proximity to life science entities, driving growth and technological advances within each cluster.  These locations are characterized by high barriers to entry for new landlords, high barriers to exit for client tenants and limited supply of available space.  They represent highly desirable locations for tenancy by life science entities because of the close proximity to concentrations of specialized skills, knowledge, institutions, and related businesses.  Our strategy also includes drawing upon our deep and broad life science and real estate relationships in order to attract new and leading life science client tenants and value-added real estate.  We executed our initial public offering in 1997 and received our investment-grade ratings in 2011.

As of March 31, 2013, we had 173 properties aggregating approximately 16.7 million rentable square feet, composed of approximately 14.2 million rentable square feet of operating properties, approximately 2.1 million rentable square feet undergoing active development, and approximately 0.4 million rentable square feet undergoing active redevelopment.  Our operating properties were approximately 93.0% leased as of March 31, 2013.   Investment-grade client tenants represented 46% of our total annualized base rent as of March 31, 2013.  The comparability of financial data from period to period is affected by the timing of our property acquisition, development, and redevelopment activities.

Value-added opportunities and external growth

During the three months ended March 31, 2013, we executed leases aggregating 355,000 and 102,000 rentable square feet, respectively, related to our development and redevelopment projects.

Our initial stabilized yield on a cash basis reflects cash rents at date of stabilization and does not reflect contractual rent escalations beyond the stabilization date.  Our cash rents related to our value-added projects are expected to increase over time and our average stabilized cash yields are expected, in general, to be greater than our initial stabilized yields.  Initial stabilized yield is calculated as the quotient of the estimated amounts of NOI and our investment in the property at stabilization (“Initial Stabilized Yield”).

The following table summarizes the commencement of key development projects (dollars in thousands, except per rentable square foot amounts):

Investment Initial

Balance sheet strategy and significant milestones

Our balance sheet strategy continues to focus on our leverage of net debt to adjusted EBITDA of approximately 6.5x targeted by December 31, 2013, by funding our significant Class A development and redevelopment projects in top life science cluster locations with leverage-neutral sources of capital and with the continuing execution of our asset recycling program. Our leverage will reflect periodic increases and decreases quarter to quarter as we execute and deliver our construction projects and capital plan, including our asset sales program.  See “Liquidity and Capital Resources – Sources and Uses of Capital” for additional information.  Our strategy to improve leverage includes:

·                  We expect growth in annualized EBITDA from the fourth quarter 2012 to the fourth quarter 2013 due primarily to the completion of significant value-added projects; 93% leased;

·                  We continue to execute our asset recycling program to monetize non-strategic income-producing and non-income producing assets to reduce outstanding debt and provide funds for reinvestment into Class A, CBD, and urban locations in close proximity to leading academic medical research centers;

·                        We sold $124.3 million of income-producing asset sales during the three months ended March 31, 2013; assets sold in first quarter of 2013 generated a weighted-average unlevered internal rate of return of 11% during our ownership period);

·                        We are targeting sales of $209 million to $259 million of non-income-producing assets for the remainder of the year ended December 31, 2013;

·                  $45 million of non-income-producing asset sales under negotiation;

·                  $60 million to $70 million projected partial sale of an interest in the ground-up development of 75/125 Binney Street;

·                  $104 million to $144 million to be identified in the near term;

·                  We expect to continue our present strategy of minimizing the issuance of common equity to achieve a net debt to adjusted EBITDA ratio of approximately 6.5x targeted by December 31, 2013;

·                  Our liquidity available under our unsecured senior line of credit and from cash and cash equivalents was approximately $1.0 billion as of March 31, 2013; and

·                  We anticipate reducing our unhedged variable rate debt as a percentage of total debt to less than 18% targeted by December 31, 2013.

As of March 31, 2013, we have completed all significant sales of income-producing assets targeted for 2013.  See our real estate sales discussion in our Sources and Uses of Capital section on page 62.  In addition to the asset sales completed in the first quarter of 2013, we have targeted the sale of non-income-producing assets ranging from $209 to $259 million.  See pages 56 and 57 for additional information on our target non-income-producing asset sales for 2013.

Results

Core operations

The key elements to our strategy include our consistent focus on high-quality assets and operations in the top life science cluster locations; our properties are located adjacent to life science entities, driving growth and technological advances within each cluster.  These adjacency locations are characterized by high barriers to entry for new landlords, high barriers to exit for client tenants, and limited supply of available space.  They represent highly desirable locations for tenancy by life science entities because of the close proximity to concentrations of specialized skills, knowledge, institutions, and related businesses.  Our strategy also includes drawing upon our deep and longstanding life science and real estate relationships in order to attract new and leading life science client tenants that provide us with our unique ability to create value through strong tenant retention and strategic development and redevelopment projects.

For the three months ended March 31, 2013, we executed a total of 44 leases for approximately 703,000 rentable square feet at 29 different properties (excluding month-to-month leases).  Of this total, approximately 156,000 rentable square feet related to new or renewal leases of previously leased space (renewed/re-leased space), and approximately 547,000 rentable square feet related to developed, redeveloped, or previously vacant space.  Of the 547,000 rentable square feet, approximately 457,000 rentable square feet related to our development or redevelopment projects, and the remaining approximately 90,000 rentable square feet related to previously vacant space.  Rental rates for renewed/re-leased spaces were, on average, approximately 5.9% higher on a cash basis and approximately 12.7% higher on a GAAP basis than rental rates for the respective expiring leases.  Additionally, we granted tenant concessions, including free rent averaging approximately 1.2 months, with respect to the 703,000 rentable square feet leased during the three months ended March 31, 2013.  Approximately 65.9% of the number of leases executed during the three months ended March 31, 2013, did not include concessions for free rent.  The weighted average lease term based on leased square feet for the leases executed during the three months ended March 31, 2013, was 8.7 years.

As of March 31, 2013, 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.  Additionally, approximately 96% of our leases (on a rentable square footage basis) contained effective annual rent escalations that were either fixed or indexed based on a consumer price index or another index, and approximately 92% of our leases (on a rentable square footage basis) provided for the recapture of certain capital expenditures.

Development, Redevelopment, and Future Value-Added Projects

A key component of our business model is our value-added development and redevelopment projects.  These programs are focused on providing high-quality, generic, and reusable life science laboratory space to meet the real estate requirements of a wide range of clients in the life science industry.  Upon completion, each value-added project is expected to generate significant revenues and cash flows.  Our development and redevelopment projects are generally in locations that are highly desirable to life science entities, which we believe results in higher occupancy levels, longer lease terms, and higher rental income and returns.

Development projects generally consist of the ground-up development of generic and reusable life science laboratory facilities.  Redevelopment projects generally consist of the permanent change in use of office, warehouse, and shell space into generic life science laboratory space.  We anticipate execution of new active development projects for aboveground vertical construction of new life science laboratory space generally with significant pre-leasing.  Preconstruction activities include entitlements, permitting, design, site work, and other activities prior to commencement of vertical construction of aboveground shell and core improvements.  Our objective also includes the advancement of preconstruction efforts to reduce the time required to deliver projects to prospective client tenants.  These critical activities add significant value for future ground-up development and are required for the vertical construction of buildings.  Ultimately, these projects will provide high-quality facilities for the life science industry and are expected to generate significant revenue and cash flows for the Company.

As of March 31, 2013, we had six ground-up development projects in process, including an unconsolidated joint venture development project, aggregating approximately 1,854,859 rentable square feet.  We also had seven projects undergoing conversion into laboratory space through redevelopment, aggregating approximately 331,380 rentable square feet.  These projects, along with recently delivered projects, certain future projects, and contribution from same properties, are expected to contribute significant increases in rental income, NOI, and cash flows.

Table of Contents

As of March 31, 2013, our active development and redevelopment projects represent 13% of gross investments in real estate, a significant amount of which is pre-leased and expected to be primarily delivered over the next one to eight quarters.  Land undergoing preconstruction activities represents 5% of gross investment in real estate.  The largest project primarily included in land undergoing preconstruction consists of our 1.2 million developable square feet at Alexandria Center™ at Kendall Square in East Cambridge, Massachusetts.  Land held for future development represent 4% of our non-income-producing assets.  Over the next few years, we may also identify certain land parcels for potential sale.  Non-income-producing assets as a percentage of our gross investments in real estate is targeted to decrease to a range from 15% to 17% by December 31, 2013, and targeted to be 15% or less for the subsequent periods.

(1)             All project information, including rentable square feet; investment; Initial Stabilized Yields; and project start, occupancy and stabilization dates, relates to the discrete portion of each property undergoing active development or redevelopment.  A redevelopment project does not necessarily represent the entire property or the entire vacant portion of a property.  Our Initial Stabilized Yield on a cash basis reflects cash rents at date of stabilization and does not reflect contractual rent escalations beyond the stabilization date.  Our cash rents related to our value-added projects are expected to increase over time and our average stabilized cash yields are expected, in general, to be greater than our Initial Stabilized Yields.  Our estimates for initial cash and GAAP yields, and total costs at completion, represent our initial estimates at the commencement of the project.  We expect to update this information upon completion of the project, or sooner if there are significant changes to the expected project yields or costs.  As of March 31, 2013, 96% of our leases contained annual rent escalations that were either fixed or based on a consumer price index or another index

(1)             Our asset base also includes non-laboratory space (office, warehouse, and industrial space) identified for future conversion into life science laboratory space through redevelopment.  These spaces are classified in investments in real estate, net, in the condensed consolidated balance sheets.

As of March 31, 2013, our rental properties, net, in Asia, consisted of five operating properties aggregating approximately 603,987 square feet, with occupancy of 67.1%.  Annualized base rent of our operating properties in Asia was approximately $4.3 million as of March 31, 2013.  Our primary sources of revenues are rental income and tenant recoveries from leases of our properties.

We also had construction projects in Asia aggregating approximately 718,119 and 734,444 rentable square feet as of March 31, 2013, and December 31, 2012, respectively.

Our investments in real estate, net, in Asia, consisted of the following as of March 31, 2013 (dollars in thousands, except per square foot amounts):

Balance sheet

Our balance sheet capital strategy in 2013 will continue to focus on funding our significant development and redevelopment projects in 2013 with leverage-neutral sources of capital and with the continuing execution of our asset recycling program while reducing our net debt to adjusted earnings before interest, taxes, depreciation, and amortization (“Adjusted EBITDA”) to approximately 6.5x by December 31, 2013.

50


Table of Contents

We expect to source capital in excess of our projected construction spending for 2013.  As more fully described under “Liquidity and Capital Resources – Sources and Uses of Capital,” we estimate our disclosed sources of capital that our asset recycling program will range from $334 million to $397 million, as we execute on the sale of income-producing and non-income-producing assets.  Our projected cash flows from operating activities after payment of dividends will generate capital ranging from $130 million to $150 million.  Common stock offering proceeds under our “at the market” common stock offering program are projected to range from $125 million to $175 million.  These proceeds aggregate a range from $589 million to $722 million and will fund our projected range of construction spending for 2013 from $570 million to $620 million.  We expect this excess capital, combined with projected growth in NOI from development and redevelopment projects described in our table at “Item 2. Properties – Development Projects in North America,” will improve our net debt to Adjusted EBITDA to approximately 6.5x targeted by December 31, 2013.

As of March 31, 2013, we had three assets held for sale.  We may identify additional assets for potential sale in 2013 and thereafter.  We expect to invest net proceeds from asset sales into construction projects located in key “brain trust” cluster markets.

Investment-grade ratings and key credit metrics

In July 2011, we received investment-grade ratings from two major rating agencies.  Receipt of our investment-grade ratings was a significant milestone that we believe will provide long-term value to our debt and equity stakeholders.  Key strengths of our balance sheet and business that highlight our investment-grade credit profile include balance sheet liquidity, a diverse and creditworthy client tenant base, well-located properties proximate to leading research institutions, favorable lease terms, stable occupancy and cash flows, and demonstrated life science and real estate expertise.  This significant milestone broadens our access to another key source of debt capital and allows us to continue to pursue our long-term capital, investment, and operating strategies.  The issuance of investment-grade unsecured senior notes payable has allowed us to begin the transition from bank debt financing to unsecured senior notes payable, from variable rate debt to fixed rate debt, and from short-term debt to long-term debt.  While this transition of bank debt is in process, we will utilize interest rate swap agreements to reduce our interest rate risk.  Our unhedged variable rate debt as a percentage of total debt is targeted to decrease to less than 18% by December 31, 2013.

**** Three Months Ended March 31,
Key Credit Metrics (1) 2013 2012

Critical Accounting Policies

Refer to our annual report on Form 10-K for the year ended December 31, 2012, for a discussion of our critical accounting policies, which include rental properties, net, land held for future development, construction in progress, discontinued operations, impairment of long-lived assets, capitalization of costs, accounting for investments, interest rate hedge agreements, and recognition of rental income and tenant recoveries.  There have been no significant changes to these policies during the three months ended March 31, 2013.

Results of operations

Same Properties

As a result of changes within our total property portfolio, the financial data presented in the table in “Comparison of the Three Months Ended March 31, 2013, to the Three Months Ended March 31, 2012” shows significant changes in revenue and expenses from period to period.  In order to supplement an evaluation of our results of operations over a given period, we analyze the operating performance for all properties that were fully operating for the entire periods presented (herein referred to as “Same Properties”) separate from properties acquired subsequent to the first period presented, properties undergoing active development and active redevelopment, and corporate entities (legal entities performing general and administrative functions), which are excluded from same property results (herein referred to as “Non-Same Properties”). Additionally, rental revenues from lease termination fees, if any, are excluded from the results of operations of the Same Properties.

The following table reconciles same properties to total properties for the three months ended March 31, 2013:

Rental revenues

Total rental revenues for the three months ended March 31, 2013, increased by $10.6 million, or 11%, to $111.8 million, compared to $101.2 million for the three months ended March 31, 2012.  The increase was due to rental revenues from our Non-Same Properties, including 12 development and redevelopment projects that were completed and delivered after January 1, 2012, and one operating property that was acquired after January 1, 2012.

Tenant recoveries

Tenant recoveries for the three months ended March 31, 2013, compared to the three months ended March 31, 2012, increased by $3.7 million, or 12%, to $35.6 million, compared to an increase of $4.7 million, or 12%, of rental operating expenses.  Same Properties tenant recoveries increased by $1.5 million, while Same Properties rental operating expenses increased by $2.1 million, primarily due to increased operating costs related to colder weather and higher property taxes due to increases in tax rates for our properties located in Massachusetts in the three months ended March 31, 2013, compared to the three months ended March 31, 2012.  Occupancy of Same Properties was 94.1% and 93.8% as of March 31, 2013 and 2012, respectively.  Non-Same Properties tenant recoveries increased by $2.3 million as a result of a Non-Same Properties rental operating expense increase of $2.7 million. As of March 31, 2013, 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.

Other income

Other income for the three months ended March 31, 2013 and 2012, of $3.0 million and $2.6 million, respectively, was as follows (in thousands):

Three Months Ended March 31,
Component 2013 2012 Change
Management fee income $ 1,606 $ 49 $ 1,557
Interest income 1,327 607 720
Investment income 60 1,972 (1,912 )
Total other income $ 2,993 $ 2,628 $ 365

Rental operating expenses

Total rental operating expenses for the three months ended March 31, 2013, increased by $4.7 million, or 12%, to $45.2 million, compared to $40.5 million for the three months ended March 31, 2012.  Approximately $2.7 million of the increase was due to an increase in rental operating expenses from our Non-Same Properties, primarily related to 12 development and redevelopment projects that were completed and delivered after January 1, 2012, and one operating property that was acquired after January 1, 2012.

General and administrative expenses

General and administrative expenses for the three months ended March 31, 2013, increased by $1.2 million, or 13%, to $11.6 million, compared to $10.4 million for the three months ended March 31, 2012.  The increase in general and administrative expenses was related to the timing of certain professional fees and an increase in the number of employees related to the growth in both the depth and breadth of our operations in multiple markets.  During the three months ended March 31, 2013, our average number of employees increased by 17 employees, or 8%, to 221, compared to an average of 204 for the three months ended March 31, 2012.  As a percentage of total revenues, general and administrative expenses were 7.7% and 7.6%, respectively, for the three months ended March 31, 2013 and 2012.

Interest expense

Interest expense for the three months ended March 31, 2013, increased by $1.8 million, or 11%, to $18.0 million, compared to $16.2 million for the three months ended March 31, 2012, detailed as follows (in thousands):

**** Three Months Ended March 31,
Component 2013 2012 Change
Secured notes payable $ 9,802 $ 10,108 $ (306 )
Unsecured senior convertible notes 7 222 (215 )
Unsecured senior notes payable 6,335 2,182 4,153
Unsecured senior line of credit 2,894 5,786 (2,892 )
Unsecured senior bank term loans 6,226 4,728 1,498
Interest rate swaps 4,308 5,775 (1,467 )
Amortization of loan fees and other interest 2,469 2,691 (222 )
Subtotal 32,041 31,492 549
Capitalized interest (14,021 ) (15,266 ) 1,245
Total interest expense $ 18,020 $ 16,226 $ 1,794

Interest expense increased primarily due to the issuance of our unsecured senior notes payable in February 2012 and an increase in the balance outstanding on our unsecured senior bank term loans since January 1, 2012.  This increase was partially offset by repayments of two secured notes payable approximating $15.4 million and repurchases of our 3.70% unsecured senior convertible notes  (“3.70% Unsecured Senior Convertible Notes”) aggregating $84.7 million since January 1, 2012.  Interest expense related to our unsecured senior line of credit also decreased, primarily due to a decrease in the effective interest rate of our unsecured senior line of credit from 2.7% as of March 31, 2012, to 1.4% as of March 31, 2013, as a result of the reduced interest rate provided by our April 2012 amendment.  We have entered into certain interest rate swap agreements to hedge a portion of our exposure primarily related to variable interest rates associated with our unsecured senior line of credit and unsecured senior bank term loans (see “Liquidity and Capital Resources – Contractual Obligations – Interest Rate Swap Agreements”).

Depreciation and amortization

Depreciation and amortization for the three months ended March 31, 2013, increased by $4.3 million, or 10%, to $46.1 million, compared to $41.8 million for the three months ended March 31, 2012.  The increase resulted primarily from increased depreciation related to building improvements, including 12 development and redevelopment projects that were completed and delivered after January 1, 2012, and one operating property that was acquired after January 1, 2012.

Income from discontinued operations, net

Income from discontinued operations, net, of $0.8 million for the three months ended March 31, 2013, includes the results of operations of three operating properties that were classified as “held for sale” and the results of operations of six properties sold during the three months ended March 31, 2013.

Income from discontinued operations, net, for the three months ended March 31, 2012, includes the results of operations of three operating properties that were classified as “held for sale” as of March 31, 2013, the results of operations of six properties sold during the three months ended March 31, 2013, and the results of operations of six properties sold during the year ended December 31, 2012.

Projected results

Based on our current view of existing market conditions and certain current assumptions, we have updated guidance for earnings per share attributable to Alexandria Real Estate Equities, Inc.’s common stockholders – diluted and FFO per share attributable to Alexandria Real Estate Equities, Inc.’s common stockholders – diluted for the year ended December 31, 2013, as set forth in the table below.  The table below provides a reconciliation of FFO per share attributable to Alexandria Real Estate Equities, Inc.’s common stockholders – diluted, a non-GAAP measure, to earnings per share, the most directly comparable GAAP measure and other key assumptions included in our guidance for the year ended December 31, 2013.

Guidance for the Year Ended December 31, 2013 Reported on April 29, 2013 Reported on February 7, 2013
Earnings per share attributable to Alexandria Real Estate Equities, Inc.’s common stockholders – diluted $1.43 to $1.59 $1.41 to $1.61
Depreciation and amortization $2.95 to $3.11 $2.93 to $3.13
Loss on sale of real estate $0.01
Other $(0.01)
FFO per share attributable to Alexandria Real Estate Equities, Inc.’s common stockholders – diluted $4.46 to $4.62 $4.44 to $4.64
Key projection assumptions:
Same property net operating income growth – cash basis 4% to 7% 4% to 7%
Same property net operating income growth – GAAP basis Up to 3% 0% to 3%
Rental rate steps on lease renewals and re-leasing of space – cash basis Up to 2% Flat to slightly positive
Rental rate steps on lease renewals and re-leasing of space – GAAP basis Up 5% to 10% Up 5% to 10%
Occupancy percentage for all operating properties at December 31, 2013 93.9% to 94.3% 93.9% to 94.3%
Straight-line rents $24 to $26 million $24 to $26 million
Amortization of above and below market leases $3 to $4 million $3 to $4 million
General and administrative expenses $48 to $51 million $48 to $51 million
Capitalization of interest $47 to $53 million $47 to $53 million
Interest expense, net $74 to $84 million $74 to $84 million
Net debt to adjusted EBITDA for the annualized three months ended December 31, 2013 6.5x 6.5x
Fixed charge coverage ratio for the annualized three months ended December 31, 2013 2.9x to 3.0x 2.9x to 3.0x

On a short-term basis, our unhedged variable rate debt as a percentage of total debt may range up to 30%. Our strategy is to have unhedged variable rate debt available for repayment as we issue unsecured senior notes payable, extend our maturity profile, transition variable rate debt to fixed rate debt, and enhance our long-term capital structure.  Our unhedged variable rate debt as a percentage of total debt is targeted to decrease to less than 18% by December 31, 2013.

Monetization of non-income-producing assets

Non-income-producing assets as a percentage of our gross investments in real estate is targeted to decrease to a range of 15% to 17% by December 31, 2013.  As of March 31, 2013, we had approximately $579 million and $141 million of construction in progress related to our five North American development and seven North American redevelopment projects, respectively.  The completion of these projects, along with recently delivered projects, certain future projects, and contributions from same properties, is expected to contribute significant increases in rental income, NOI, and cash flows.  Operating performance assumptions related to the completion of our North American development and redevelopment projects, including the timing of initial occupancy, stabilization dates, and Initial Stabilized Yields, are included on pages 47 and 48.  Certain key assumptions regarding our projections, including the impact of various development and redevelopment projects, are included in the tables above and on page 63.

The completion of our development and redevelopment projects will result in increased interest expense and other direct project costs, because these project costs will no longer qualify for capitalization and these costs will be expensed as incurred.  Our projection assumptions for depreciation and amortization, general and administrative expenses, capitalization of interest, interest expense, net, and NOI growth are included in the tables on page 62 and are subject to a number of variables and uncertainties, including those discussed under the “Forward-looking Statements” section of Part I, the “Risk Factors” section of Item 1A, and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section under Item 7, of our annual report on Form 10-K for the year ended December 31, 2012.  To the extent our full year earnings guidance is updated during the year, we will provide additional disclosure supporting reasons for any significant changes to such guidance.  Further, we believe NOI is a key performance indicator and is useful to investors as a performance measure because, when compared across periods, NOI reflects the impact on operations from trends in occupancy rates, rental rates, and operating costs, providing perspective not immediately apparent from income from continuing operations.

Liquidity and capital resources

Overview

We expect to meet certain long-term liquidity requirements, such as requirements for property acquisitions, development, redevelopment, other construction projects, capital improvements, tenant improvements, leasing costs, non-revenue-generating expenditures, and scheduled debt maturities, through net cash provided by operating activities, periodic asset sales, and long-term secured and unsecured indebtedness, including borrowings under our unsecured senior line of credit, unsecured senior bank term loans, and the issuance of additional debt and/or equity securities.

We expect to continue meeting our short-term liquidity and capital requirements, as further detailed in this section, generally through our working capital and net cash provided by operating activities.  We believe that the net cash provided by operating activities will continue to be sufficient to enable us to make the distributions necessary to continue qualifying as a REIT.

Over the next several years, our balance sheet, capital structure, and liquidity objectives are as follows:

·                  Reduce leverage as a percentage of debt to total gross assets and improve our ratio of debt to earnings before interest, taxes, depreciation, and amortization;

·                   Execute selective sales of income-producing and non-income-producing assets as a source of capital while minimizing the issuance of common equity;

·                  Maintain diverse sources of capital, including sources from net cash flows from operating activities, unsecured debt, secured debt, selective asset sales, joint ventures, preferred stock, and common stock;

·                  Manage the amount of debt maturing in a single year;

·                  Mitigate unhedged variable rate debt exposure by transitioning our balance sheet debt from short-term and medium-term variable rate bank debt to long-term unsecured fixed rate debt and utilize interest rate swap agreements in the interim period during this transition of debt;

·                  Maintain adequate liquidity from net cash provided by operating activities, cash and cash equivalents, and available borrowing capacity under our unsecured senior line of credit;

·                  Maintain available borrowing capacity under our unsecured senior line of credit in excess of 50% of the total commitments of $1.5 billion, except temporarily as necessary;

·                  Fund preferred stock and common stock dividends from net cash provided by operating activities;

·                  Retain positive cash flows from operating activities after payment of dividends for reinvestment in acquisitions and/or development and redevelopment projects; and

·                  Reduce our non-income-producing assets as a percentage of our gross investment in real estate.

Cash flows

We report and analyze our cash flows based on operating activities, investing activities, and financing activities.  The following table summarizes changes in the Company’s cash flows for the three months ended March 31, 2013 and 2012 (in thousands):

Three Months Ended March 31,
2013 2012 Change
Net cash provided by operating activities $ 47,241 $ 49,685 $ (2,444 )
Net cash used in investing activities $ (69,524 ) $ (124,248 ) $ 54,724
Net cash (used in) provided by financing activities $ (31,509 ) $ 71,351 $ (102,860 )

Operating activities

Cash flows provided by operating activities consisted of the following amounts (in thousands):

Three Months Ended March 31,
2013 2012 Change
Net cash provided by operating activities $ 47,241 $ 49,685 $ (2,444 )
Changes in assets and liabilities 29,093 19,801 9,292
Net cash provided by operating activities before changes in assets and liabilities $ 76,334 $ 69,486 $ 6,848

Cash flows provided by operating activities are primarily dependent on the occupancy level of our asset base, rental rates of our leases, the collectability of rent and recovery of operating expenses from our tenants, the delivery of development projects and the timing and delivery of redevelopment projects, and the amount of general and administrative costs.  Net cash provided by operating activities for the three months ended March 31, 2013, decreased by $2.4 million, or 5%, to $47.2 million, compared to $49.7 million for the three months ended March 31, 2012.   Excluding the changes in assets and liabilities, net cash provided by operating activities increased by approximately $6.8 million, 10%, to $76.3 million, compared to $69.5 million for the three months ended March 31, 2012.  This increase was primarily attributable to an increase in our Same Property cash net operating income of approximately $7.0 million, or 9%, to $86.0 million, compared to $79.0 million for the three months ended March 31, 2012.   As of March 31, 2013, 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.

Investing activities

Net cash used in investing activities for the three months ended March 31, 2013, was $69.5 million, compared to $124.2 million for the three months ended March 31, 2012.  This change consisted of the following amounts (in thousands):

Three Months Ended March 31,
2013 2012 Change
Proceeds from sales of properties $ 80,203 $ $ 80,203
Additions to properties (139,245 ) (120,585 ) (18,660 )
Purchase of properties (19,946 ) 19,946
Other (10,482 ) 16,283 (26,765 )
Net cash used in investing activities $ (69,524 ) $ (124,248 ) $ 54,724

The change in net cash used in investing activities for the three months ended March 31, 2013, is primarily due to proceeds from sales of properties, a lower investment amount in property acquisitions in the three months ended March 31, 2013, as compared to the three months ended March 31, 2012, offset by increased capital expenditures related to our development and redevelopment projects during the three months ended March 31, 2013.

Value-added opportunities and external growth

As of March 31, 2013, we had six ground-up development projects in process, including an unconsolidated joint venture development project, aggregating approximately 1,854,859 rentable square feet.  We also had seven projects undergoing conversion into laboratory space through redevelopment, aggregating approximately 620,111 rentable square feet.  These projects, along with recently delivered projects, certain future projects, and contribution from same properties, are expected to contribute significant increases in rental income, NOI, and cash flows.

Our initial stabilized yield on a cash basis reflects cash rents at date of stabilization and does not reflect contractual rent escalations beyond the stabilization date.  We expect, on average, our cash rents related to our value-added projects to increase over time pursuant to contractual rent escalations.  As of March 31, 2013, 96% of our leases contained annual rent escalations that were either fixed or based on a consumer price index or another index.

During the three months ended March 31, 2013, we executed leases aggregating 355,000 and 102,000 rentable square feet related to our development and redevelopment projects, respectively.

The following table summarizes the commencement of key development projects for the three months ended March 31, 2013 (dollars in thousands, except per square foot amounts):

4.60% unsecured senior notes payable offering

In February 2012, we completed the issuance of our 4.60% unsecured senior notes (“4.60% Unsecured Senior Notes”) due in April 2022.  Net proceeds of approximately $544.6 million were used to repay certain outstanding variable rate bank debt, including the entire $250.0 million of our 2012 unsecured senior bank term loan (“2012 Unsecured Senior Bank Term Loan”), and approximately $294.6 million of outstanding borrowings under our unsecured senior line of credit.  In connection with the retirement of our 2012 Unsecured Senior Bank Term Loan, we recognized a loss on early extinguishment of debt of approximately $0.6 million related to the write-off of unamortized loan fees for the three months ended March 31, 2012.

The requirements of, and our actual performance with respect to, the key financial covenants under our unsecured senior notes payable as of March 31, 2013, are as follows:

Covenant Ratios (1) Requirement Actual (2)
Total Debt to Total Assets Less than or equal to 60% 40%
Consolidated EBITDA to Interest Expense Greater than or equal to 1.5x 5.6x
Unencumbered Total Asset Value to Unsecured Debt Greater than or equal to 150% 246%
Secured Debt to Total Assets Less than or equal to 40% 9%
(1) For a definition of the ratios used in the table above, refer to the indenture dated February 29, 2012 (the “Indenture”), which governs the unsecured senior notes payable, which was filed as an exhibit to our Current Report on Form 8-K filed with the SEC on February 29, 2012.
--- ---
(2) Actual covenants are calculated pursuant to the specific terms of the Indenture.

In addition, the terms of the Indenture, among other things, limit the ability of the Company, Alexandria Real Estate Equities, L.P., and the Company’s subsidiaries to (1) consummate a merger, or consolidate or sell all or substantially all of the Company’s assets, and (2) incur certain secured or unsecured indebtedness.

In February 2012, we repaid the entire $250.0 million outstanding balance on our 2012 Unsecured Senior Bank Term Loan.  In connection with the retirement of our 2012 Unsecured Senior Bank Term Loan, we recognized a loss on early extinguishment of debt of approximately $0.6 million related to the write-off of unamortized loan fees for the three months ended March 31, 2012.

In April 2012, we also amended our $1.5 billion unsecured senior line of credit with Merrill Lynch, Pierce, Fenner & Smith Incorporated, J.P. Morgan Securities Inc., and Citigroup Global Markets Inc. as joint lead arrangers, and certain lenders, to extend the maturity date of our unsecured senior line of credit, provide an accordion option for up to an additional $500.0 million, and reduce the interest rate for outstanding borrowings.  The maturity date of the unsecured senior line of credit was extended to April 2017, assuming we exercise our sole right to extend the stated maturity date twice by an additional six months after each exercise.  Borrowings under the unsecured senior line of credit will bear interest at LIBOR or the base rate specified in the amended unsecured senior line of credit agreement, plus in either case a specified margin (the “Applicable Margin”).  The Applicable Margin for LIBOR borrowings under the unsecured senior line of credit was set at 1.20%, down from 2.40% in effect immediately prior to the modification.  In addition to the Applicable Margin, our unsecured senior line of credit is subject to an annual facility fee of 0.25%.  In connection with the modification of our unsecured senior line of credit in April 2012, we recognized a loss on early extinguishment of debt of approximately $1.6 million related to the write-off of a portion of unamortized loan fees for the three months ended June 30, 2012.

The requirements of, and our actual performance with respect to, the key financial covenants under our unsecured senior line of credit as of March 31, 2013, are as follows:

Covenant Ratios (1) Requirement Actual (2)
Leverage Ratio Less than or equal to 60.0% 38%
Fixed Charge Coverage Ratio Greater than or equal to 1.50x 2.5x
Secured Debt Ratio Less than or equal to 40.0% 9%
Unsecured Leverage Ratio Less than or equal to 60.0% 44%
Unsecured Interest Coverage Ratio Greater than or equal to 1.75x 6.8x
(1) For a definition of the ratios used in the table above, refer to the amended unsecured senior line of credit and unsecured senior bank term loan agreements, dated as of April 30, 2012, which were filed as an exhibit to our Quarterly Report on Form 10-Q filed with the SEC on August 8, 2012.

“At the market” common stock offering program

In June 2012, we established an “at the market” common stock offering program under which we may sell, from time to time, up to an aggregate of $250.0 million of our common stock through our sales agents, BNY Mellon Capital Markets, LLC and Credit Suisse Securities (USA) LLC, during a three-year period.  Net proceeds from the sales were used to pay down the outstanding balance on our unsecured senior line of credit or other borrowings, and for general corporate purposes.  As of March 31, 2013, approximately $150.0 million of our common stock remained available for issuance under the “at the market” common stock offering program.

Dividends

During the three months ended March 31, 2013 and 2012, we paid the following dividends (in thousands):

Three Months Ended March 31,
2013 2012 Change
Common stock dividends $ 35,687 $ 30,386 $ 5,301
Series C Preferred Stock dividends 2,714 (2,714 )
Series D Preferred Stock dividends 4,375 4,375
Series E Preferred Stock dividends 2,096 2,096
$ 42,158 $ 37,475 $ 4,683

The increase in dividends paid on our common stock is primarily due to an increase in the related dividends to $0.60 per common share for the three months ended March 31, 2013, from $0.49 per common share for the three months ended March 31, 2012.  The increase was also due to an increase in common stock outstanding.  Total common stock outstanding as of March 31, 2013, was 63,317,296 shares, compared to 61,634,645 shares as of March 31, 2012.

Sources and uses of capital

We expect that our principal liquidity needs for the year ended December 31, 2013, will be satisfied by the following multiple sources of capital as shown in the table below. There can be no assurance that our sources and uses of capital will not be materially higher or lower than these expectations. Our liquidity available under our unsecured senior line of credit and from cash and cash equivalents was approximately $1.0 billion as of March 31, 2013.

(3) Total construction spending for 2013 increased approximately $25 million at the mid-point of our guidance since last quarter primarily as a result of our estimated share of capital required for the commencement of two new ground-up development projects during the first quarter of 2013. Our estimated construction spend for 2013 increased by approximately $13 million as a result of the commencement of our 100% pre-leased development at 269 East Grand Avenue. The total estimated cost at completion for 75/125 Binney Street has not changed since our estimate as of December 31, 2012; however, the timing of construction and completion of our projected joint venture results in an increase in our estimated share of capital contributions to fund the completion of the project by approximately $10 million.

(5) Our guidance has assumed no acquisitions, but we continuously and intensively review a pipeline of opportunistic acquisitions in our key core cluster markets that we would expect to fund on a leverage-neutral basis.

The key assumptions behind the sources and uses of capital in the table above are a favorable capital market environment and performance of our core operations in areas such as delivery of current and future development and redevelopment projects, leasing activity, and renewals.  Our expected sources and uses of capital are subject to a number of variables and uncertainties, including those discussed under the “Forward-looking statements” section of Part I, the “Risk Factors” section of Item 1A, and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section under Item 7, of our annual report on Form 10-K for the year ended December 31, 2012.  We expect to update our forecast of sources and uses of capital on a quarterly basis.

Projected unconsolidated joint venture

Our guidance for the year ended December 31, 2013, assumes a transfer of 50% of our ownership interest in the 75/125 Binney Street project to a new joint venture partner which will be accounted for as a sale of an interest in our investment in the ground-up development, with the resulting entity presented as an unconsolidated joint venture (the “Binney JV”) in our financial statements.  This projected sale of an interest in our investment in the ground-up development is included in our total non-income-producing asset sales target for 2013. We expect the sale proceeds to range from $60 million to $70 million and to exceed our share of the remaining investment of $44 million through the completion of the project.   We also anticipate the unconsolidated Binney JV to obtain a secured construction loan to fund 60% to 70% of the total project costs.

The following assumptions are included in our guidance for funding the cost to complete the 75/125 Binney Street project (in millions).

Cost to Complete (1)
Nine Months Ended<br> December 31, 2013 Thereafter Total
75/125 Binney Street project – remaining cost to complete $ 91 $ 163 $ 254

(2) Represents our share of incremental investment into the Binney JV and is included in our guidance for 2013 development, redevelopment, and construction spending in a range from $570 million to $620 million. Binney JV partner capital and secured construction loan funding for 75/125 Binney Street related to our projected unconsolidated joint venture have been excluded from our construction spend forecast for 2013.

Sources of capital

Unsecured senior line of credit

We use our unsecured senior line of credit to fund working capital, construction activities, and, from time to time, acquisition of properties.  As of March 31, 2013, we had $0.9 billion available under our $1.5 billion unsecured senior line of credit.

Cash and cash equivalents

As of March 31, 2013, we had approximately $87.0 million of cash and cash equivalents.  We expect existing cash and cash equivalents, cash flows from operating activities, proceeds from asset sales, secured construction loan and unsecured senior notes payable borrowings, and issuances of common stock under our “at the market” common stock offering program to continue to be sufficient to fund our operating activities and cash commitments for investing and financing activities, such as regular quarterly dividends, scheduled debt repayments, and material capital expenditures, for at least the next 12 months, and thereafter for the foreseeable future.

Restricted cash

Restricted cash consisted of the following as of March 31, 2013, and December 31, 2012 (in thousands):

March 31,<br> 2013 December 31,<br> 2012
Funds held in trust under the terms of certain secured notes payable $ 20,870 $ 29,526
Funds held in escrow related to construction projects 5,653 5,652
Other restricted funds 3,485 4,769
Total $ 30,008 $ 39,947

The funds held in escrow related to construction projects will be used to pay for certain construction costs.

Real estate asset sales

We continue the disciplined execution of our asset recycling program to monetize non-strategic income-producing and non-income-producing assets as a source of capital while minimizing the issuance of common equity.  We target the following asset types for sale and redeploy the capital to fund active development and redevelopment projects with significant pre-leasing:

·                  Older buildings: elimination of potential capital expenditures and leasing risk;

·                  Non-strategic assets: disposition of properties not proximate to academic medical research centers in core life science cluster locations;

·                  Assets with alternative uses for buyer: transformation into non-laboratory space, such as medical office buildings, hospitals, and residential spaces;

·                  Suburban locations: reinvestment in higher-value, Class A assets in urban “brain trust” life science cluster locations; or

·                  Excess land: reduction of non-income-producing land holdings in certain clusters, while retaining specific land parcels for future growth.

Consistent with our asset recycling program described above, we completed all significant sales of non-strategic income-producing assets targeted for 2013 totaling $124.2 million.  These assets generated a weighted average unlevered internal rate of return (“IRR”) of 11% during our ownership period.  Our assets sales for the three months ended March 31, 2013 were comprised of the following (dollars in thousands, except per square foot amounts):

(2) Total construction spending for 2013 increased approximately $25 million at the mid-point of our guidance since last quarter primarily as a result of our estimated share of capital required for the commencement of two new ground-up development projects during the first quarter of 2013. Our estimated construction spend for 2013 increased by approximately $13 million as a result of the commencement of our 100% pre-leased development at 269 East Grand Avenue. The total estimated cost at completion for 75/125 Binney Street has not changed since our estimate as of December 31, 2012; however, the timing of construction and completion of our projected joint venture results in an increase in our estimated share of capital contributions to fund the completion of the project by approximately $10 million. See additional details on the 269 East Grand Avenue project on page 47 and the 75/125 Binney Street project on page 63.
(3) Estimated spending beyond 2013 will be determined at a future date and is contingent upon many factors.

(1) Major capital expenditures typically consist of significant improvements such as roof and HVAC system replacements. Due to unfavorable weather conditions, major capital expenditures are low during the three months ended March 31, of each year. Other building improvements exclude major capital expenditures.
--- ---
(2) Excludes space that has undergone redevelopment before re-tenanting.

We expect our future non-revenue-enhancing capital expenditures, tenant improvements, and leasing costs (excluding capital expenditures and tenant improvements that are recoverable from client tenants, revenue-enhancing, or related to properties that have undergone redevelopment) on a per square foot basis to approximate the amounts shown in the preceding table.

Capitalized interest for the three months ended March 31, 2013 and 2012, of approximately $14.0 million and $15.3 million, respectively, is classified in investments in real estate, net, as well as included in the table on the preceding page summarizing total capital expenditures.  In addition, we capitalized payroll and other indirect project costs related to development, redevelopment, and construction projects, including projects in Asia, aggregating approximately $3.9 million and $3.1 million for the three months ended March 31, 2013 and 2012, respectively.  Such costs are also included in the “Summary of Capital Expenditures” section on the preceding page.

We capitalize interest cost as a cost of the project only during the period for which activities necessary to prepare an asset for its intended use are ongoing, provided that expenditures for the asset have been made and interest cost has been incurred.  Indirect project costs, including construction administration, legal fees, and office costs that clearly relate to projects under development or construction, are capitalized as incurred during the period an asset is undergoing activities to prepare it for its intended use.  Additionally, should activities necessary to prepare an asset for its intended use cease, interest, taxes, insurance, and certain other direct project costs related to this asset would be expensed as incurred.  When construction activities cease and the asset is ready for its intended use, the asset is transferred out of construction in progress and classified as rental properties, net.  Additionally, if vertical aboveground construction is not initiated at completion of preconstruction activities, the land parcel will be classified as land held for future development.  Expenditures for repairs and maintenance are expensed as incurred.  Fluctuations in our development, redevelopment, and construction activities could result in significant changes to total expenses and net income.  For example, had we experienced a 10% reduction in development, redevelopment, and construction activities without a corresponding decrease in indirect project costs, including interest and payroll, total expenses would have increased by approximately $1.8 million for the three months ended March 31, 2013.

We also capitalize and defer initial direct costs to originate leases with independent third parties related to evaluating a prospective lessee’s financial condition, negotiating lease terms, preparing the lease agreement, and closing the lease transaction.  Costs that we have capitalized and deferred relate to successful leasing transactions, result directly from and are essential to the lease transaction, and would not have been incurred had that leasing transaction not occurred.  The initial direct costs capitalized and deferred also include the portion of our employees’ total compensation and payroll-related fringe benefits directly related to time spent performing activities previously described and related to the respective lease that would not have been performed but for that lease.

66


Table of Contents

Total initial direct leasing costs capitalized during the three months ended March 31, 2013 and 2012, were approximately $8.3 million and $11.5 million, respectively, of which approximately $2.6 million and $2.5 million, respectively, represented capitalized and deferred payroll costs directly related and essential to our leasing activities during such periods.

Acquisitions

We did not complete any real estate acquisitions during the three months ended March 31, 2013.

Dividends

We are required to distribute at least 90% of our REIT taxable income on an annual basis in order to continue to qualify as a REIT for federal income tax purposes.  Accordingly, we intend to make, but are not contractually bound to make, regular quarterly distributions to preferred and common stockholders from cash flow from operating activities.  All such distributions are at the discretion of our Board of Directors.  We may be required to use borrowings under our unsecured senior line of credit, if necessary, to meet REIT distribution requirements and maintain our REIT status.  We consider market factors and our performance in addition to REIT requirements in determining distribution levels.  Our forecasts of taxable income and distributions do not require significant increases in our annual common stock dividends on a per share basis in order to distribute at least 90% of our REIT taxable income for the period from January 1, 2013, through December 31, 2013.

(2) Amounts include noncontrolling interests’ share of scheduled principal maturities of approximately $21.2 million, of which approximately $20.9 million matures in 2014. See discussion under Note 5, Secured and Unsecured Senior Debt, for additional information.
(3) The maturity date of our unsecured senior line of credit is April 30, 2017, assuming we exercise our sole right to extend the maturity date of April 30, 2016, twice, by an additional six months.
(4) Our 2016 unsecured senior bank term loan (“2016 Unsecured Senior Bank Term Loan”) matures June 30, 2016, assuming we exercise our sole right to extend the maturity date of June 30, 2015, by one year.
(5) Our 2017 unsecured senior bank term loan (“2017 Unsecured Senior Bank Term Loan”) matures January 31, 2017, assuming we exercise our sole right to extend the maturity date of January 31, 2016, by one year.
(6) Estimated interest payments on our fixed rate debt and hedged variable rate debt were based upon contractual interest rates, including the impact of interest rate swap agreements, interest payment dates, and scheduled maturity dates.
(7) The interest payments on variable rate debt were based on the interest rates in effect as of December 31, 2012.

Estimated interest payments

Estimated interest payments on our fixed rate debt and hedged variable rate debt were calculated based upon contractual interest rates, including the impact of interest rate swap agreements, interest payment dates, and scheduled maturity dates.  As of March 31, 2013, approximately 68% of our debt was fixed rate debt or variable rate debt subject to interest rate swap agreements.  See additional information regarding our interest rate swap agreements under “Liquidity and Capital Resources – Contractual Obligations and Commitments – Interest Rate Swap Agreements.”  The remaining 32% of our debt is unhedged variable rate debt based primarily on LIBOR.  Interest payments on our unhedged variable rate debt have been calculated based on interest rates in effect as of March 31, 2013.  See additional information regarding our debt under Note 5, Secured and Unsecured Senior Debt, to our condensed consolidated financial statements appearing elsewhere in our annual report on Form 10-K for the year ended December 31, 2012.

Ground lease obligations

Ground lease obligations as of March 31, 2013, included leases for 25 of our properties and four land development parcels.  Excluding one ground lease related to one operating property that expires in 2036 with a net book value of approximately $7.9 million at March 31, 2013, our ground lease obligations have remaining lease terms ranging from 41 to 196 years, including extension options.

Commitments

In addition to the above, as of March 31, 2013, remaining aggregate costs under contract for the construction of properties undergoing development, redevelopment, and generic life science infrastructure improvements under the terms of leases approximated $267.1 million.  We expect payments for these obligations to occur over one to three years, subject to capital planning adjustments from time to time.  We are also committed to funding approximately $56.7 million for certain investments over the next six years.

A 100% owned subsidiary of the Company previously executed a ground lease, as ground lessee, for certain property in New York City.  The West Tower of the Alexandria Center™ for Life Science – New York City will be constructed on such ground-leased property.  In November 2012, we commenced vertical construction of the West Tower.  The ground lease provides that substantial completion of the West Tower occur by October 31, 2015, and requires satisfying conditions that include substantially completed

construction in accordance with the plans.  The ground lease also provides that by October 31, 2016, the ground lessee shall obtain a temporary or permanent certificate of occupancy for the core and shell of both the East Tower of the Alexandria Center™ for Life Science – New York City (which has occurred) and the West Tower.  In each case, the target dates above are subject to force majeure, to contractual cure rights, to other legal remedies available to ground lessees generally, and to change for any reason by agreement between both parties under the ground lease.  If the above dates are not met, the ground lease provides contractual cure rights and the ground lease does not provide for the payment of additional rent, a late fee, or other monetary penalty.

Off-balance sheet arrangements

Our off-balance sheet arrangements consist of our investment in a real estate entity that is a variable interest entity for which we are not the primary beneficiary.  We account for the real estate entity under the equity method.  The debt held by the unconsolidated real estate entity is secured by the land parcel owned by the entity, and is non-recourse to us.  See Notes 2 and 3 to our condensed consolidated financial statements appearing elsewhere in our annual report on Form 10-K for the year ended December 31, 2012.

Interest rate swap agreements

We utilize interest rate swap agreements to hedge a portion of our exposure to variable interest rates primarily associated with our unsecured senior line of credit and unsecured senior bank term loans.  These agreements involve an exchange of fixed and variable rate interest payments without the exchange of the underlying principal amount (the “notional amount”).  Interest received under all of our interest rate swap agreements is based on the one-month LIBOR rate.  The net difference between the interest paid and the interest received is reflected as an adjustment to interest expense.

The following table summarizes our interest rate swap agreements as of March 31, 2013 (in thousands):

Interest Pay Fair Value as of Notional Amount in Effect as of
Transaction Date Effective Date Termination Date Rate (1) March 31, 2013 (2) March 31, 2013 December 31, 2013

December 2011 December 31, 2013 December 31, 2014 0.976% (1,674 ) 250,000
Total $ (16,486 ) $ 1,000,000 $ 700,000
(1) In addition to the interest pay rate, borrowings outstanding under our unsecured senior line of credit and unsecured senior bank term loans include an applicable margin currently ranging from 1.20% to 1.75%.
--- ---
(2) Includes accrued interest and credit valuation adjustment.

We have entered into master derivative agreements with each counterparty.  These master derivative agreements (all of which are adapted from the standard International Swaps and Derivatives Association, Inc. form) define certain terms between the Company and each counterparty to address and minimize certain risks associated with our interest rate swap agreements.  In order to limit our risk of non-performance by an individual counterparty under our interest rate swap agreements, our interest rate swap agreements are spread among various counterparties.  As of March 31, 2013 and 2012, the largest aggregate notional amount of the interest rate swap agreements in effect at any single point in time with an individual counterparty was $375.0 million.  If one or more of our counterparties fail to perform under our interest rate swap agreements, we may incur higher costs associated with our variable rate LIBOR-based debt than the interest costs we originally anticipated.

As of March 31, 2013, the fair values of our interest rate swap agreements were classified in accounts payable, accrued expenses, and tenant security deposits based upon their respective fair values, aggregating a liability balance of approximately $16.5 million, with the offsetting adjustment reflected as unrealized losses in accumulated other comprehensive loss in total equity.  Balances in accumulated other comprehensive loss are recognized in the period during which the hedged transactions affect earnings.  We have not posted any collateral related to our interest rate swap agreements.  For the three months ended March 31, 2013 and 2012, approximately $4.3 and $5.8 million, respectively, was reclassified from accumulated other comprehensive income to interest expense as an increase to interest expense.  During the next 12 months, we expect to reclassify approximately $14.0 million from accumulated other comprehensive loss to interest expense as an increase to interest expense.

Other resources and liquidity requirements

Under our current shelf registration statement filed with the SEC, we may offer common stock, preferred stock, debt, and other securities.  These securities may be issued from time to time at our discretion based on our needs and market conditions, including as necessary to balance our use of incremental debt capital.

We hold interests, together with certain third parties, in companies that we consolidate in our financial statements.  These third parties may contribute equity into these entities primarily related to their share of funds for construction and financing-related activities.

Exposure to environmental liabilities

In connection with the acquisition of all of our properties, we have obtained Phase I environmental assessments to ascertain the existence of any environmental liabilities or other issues.  The Phase I environmental assessments of our properties have not revealed any environmental liabilities that we believe would have a material adverse effect on our financial condition or results of operations taken as a whole, nor are we aware of any material environmental liabilities that have occurred since the Phase I environmental assessments were completed.  In addition, we carry a policy of pollution legal liability insurance covering exposure to certain environmental losses at substantially all of our properties.

Inflation

As of March 31, 2013, 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 (generally ranging from 3.0% to 3.5%) or indexed based on a consumer price index or another index.  Accordingly, we do not believe that our cash flow or earnings from real estate operations are subject to any significant risk from inflation.  An increase in inflation, however, could result in an increase in the cost of our variable rate borrowings, including borrowings related to our unsecured senior line of credit and unsecured senior bank term loans.

Non-GAAP measures

FFO and FFO, as adjusted

GAAP basis accounting for real estate assets utilizes historical cost accounting and assumes that real estate values diminish over time.  In an effort to overcome the difference between real estate values and historical cost accounting for real estate assets, the Board of Governors of NAREIT established the measurement tool of FFO.  Since its introduction, FFO has become a widely used non-GAAP financial measure among equity REITs.  We believe that FFO is helpful to investors as an additional measure of the performance of an equity REIT.  Moreover, we believe that FFO, as adjusted, is also helpful because it allows investors to compare our performance to the performance of other real estate companies between periods, and on a consistent basis, without having to account for differences caused by investment and disposition decisions, financing decisions, terms of securities, capital structures, and capital market transactions.  We compute FFO in accordance with standards established by the Board of Governors of NAREIT in its NAREIT White Paper.  The NAREIT White Paper defines FFO as net income (computed in accordance with GAAP), excluding gains (losses) from sales of depreciable real estate and land parcels and impairments of depreciable real estate (excluding land parcels), plus real estate related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures.  Impairments of real estate relate to decreases in the estimated fair value of real estate due to changes in general market conditions and do not necessarily reflect the operating performance of the properties during the corresponding period.  Impairments of real estate represent the non-cash write-down of assets when fair value over the recoverability period is less than the carrying value.  We compute FFO, as adjusted, as FFO calculated in accordance with the NAREIT White Paper, plus losses on early extinguishment of debt, preferred stock redemption charges, and impairments of land parcels, less realized gain on equity investment primarily related to one non-tenant life science entity, and the amount of such items that is allocable to our unvested restricted stock awards.  Our calculations of both FFO and FFO, as adjusted, may differ from those methodologies utilized by other equity REITs for similar performance measurements, and, accordingly, may not be comparable to those of other equity REITs.  Neither FFO nor FFO, as adjusted, should be considered as an alternative to net income (determined in accordance with GAAP) as an indication of financial performance, or to cash flows from operating activities (determined in accordance with GAAP) as a measure of liquidity, nor are they indicative of the availability of funds for our cash needs, including funds available to make distributions.

Adjusted funds from operations (“AFFO”)

AFFO is a non-GAAP financial measure that we use as a supplemental measure of our performance.  We compute AFFO by adding to or deducting from FFO, as adjusted: (1) non-revenue-enhancing capital expenditures, tenant improvements, and leasing commissions (excludes development and redevelopment expenditures); (2) effects of straight-line rent and straight-line rent on ground leases; (3) capitalized income from development projects; (4) amortization of acquired above and below market leases, loan fees, and debt premiums/discounts; (5) non-cash compensation expense; and (6) allocation of AFFO attributable to unvested restricted stock awards.

We believe that AFFO is a useful supplemental performance measure because it further adjusts to: (1) deduct certain expenditures that, although capitalized and classified in depreciation expense, do not enhance the revenue or cash flows of our properties; (2) eliminate the effect of straight-lining our rental income and capitalizing income from development projects in order to reflect the actual amount of contractual rents due in the period presented; and (3) eliminate the effect of non-cash items that are not indicative of our core operations and do not actually reduce the amount of cash generated by our operations.  We believe that eliminating the effect of non-cash charges related to share-based compensation facilitates a comparison of our operations across periods and among other equity REITs without the variances caused by different valuation methodologies, the volatility of the expense (which depends on market forces outside our control), and the assumptions and the variety of award types that a company can use.  We believe that AFFO provides useful information by excluding certain items that are not representative of our core operating results because such items are dependent upon historical costs or subject to judgmental valuation inputs and the timing of our decisions.

AFFO is not intended to represent cash flow for the period, and is intended only to provide an additional measure of performance.  We believe that net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders is the most directly comparable GAAP financial measure to AFFO.  We believe that AFFO is a widely recognized measure of the operations of equity REITs, and presenting AFFO will enable investors to assess our performance in comparison to other equity REITs.  However, other equity REITs may use different methodologies for calculating AFFO and, accordingly, our AFFO may not be comparable to AFFO calculated by other equity REITs.  AFFO should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of financial performance, or to cash flows from operating activities (determined in accordance with GAAP) as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to make distributions.

Adjusted EBITDA and Adjusted EBITDA margins

EBITDA represents earnings before interest, taxes, depreciation, and amortization (“EBITDA”), a non-GAAP financial measure, and is used by us and others as a supplemental measure of performance.  We use Adjusted EBITDA and Adjusted EBITDA margins to assess the performance of our core operations, for financial and operational decision making, and as a supplemental or additional means of evaluating period-to-period comparisons on a consistent basis.  Adjusted EBITDA also serves as a proxy for a component of a financial covenant under certain of our debt obligations.  Adjusted EBITDA is calculated as EBITDA excluding net stock compensation expense, gains or losses on early extinguishment of debt, gains or losses on sales of real estate, gains or losses on sales of land parcels, impairments of real estate, and impairments of land parcels.  We believe Adjusted EBITDA and Adjusted EBITDA margins provide investors relevant and useful information because they permit investors to view income from our operations on an unleveraged basis before the effects of taxes, non-cash depreciation and amortization, net stock compensation expense, gains or losses on early extinguishment of debt, gains or losses on sales of real estate, gains or losses on sales of land parcels, impairments of real estate, and impairments of land parcels.  By excluding interest expense and gains or losses on early extinguishment of debt, EBITDA, Adjusted EBITDA, and Adjusted EBITDA margins allow investors to measure our performance independent of our capital structure and indebtedness and, therefore, allow for a more meaningful comparison of our performance to that of other companies, both in the real estate industry and in other industries.  We believe that excluding non-cash charges related to share-based compensation facilitates a comparison of our operations across periods and among other equity REITs without the variances caused by different valuation methodologies, the volatility of the expense (which depends on market forces outside our control), and the assumptions and the variety of award types that a company can use.  We believe that adjusting for the effects of gains or losses on sales of real estate, gains or losses on sales of land parcels, impairments of real estate, and impairments of land parcels provides useful information by excluding certain items that are not representative of our core operating results.  These items are dependent upon historical costs, and are subject to judgmental inputs and the timing of our decisions.  EBITDA, Adjusted EBITDA, and Adjusted EBITDA margins have limitations as measures of our performance.  EBITDA, Adjusted EBITDA, and Adjusted EBITDA margins do not reflect our historical cash expenditures or future cash requirements for capital expenditures or contractual commitments.  While EBITDA, Adjusted EBITDA, and Adjusted EBITDA margins are relevant and widely used measures of performance, they do not represent net income or cash flows from operations as defined by GAAP, and they should not be considered as alternatives to those indicators in evaluating performance or liquidity.  Further, our computation of EBITDA, Adjusted EBITDA, and Adjusted EBITDA margins may not be comparable to similar measures reported by other companies.

The following table reconciles net income, the most directly comparable financial measure calculated and presented in accordance with GAAP, to EBITDA, Adjusted EBITDA, and Adjusted EBITDA margins, for the three months ended March 31, 2013 and 2012 (dollars in thousands):

Fixed charge coverage ratio

The fixed charge coverage ratio is useful to investors as a supplemental measure of the Company’s ability to satisfy fixed financing obligations and dividends on preferred stock.  Cash interest is equal to interest expense calculated in accordance with GAAP, plus capitalized interest, less amortization of loan fees, and amortization of debt premiums/discounts.  The fixed charge coverage ratio calculation below is not directly comparable to the computation of “Consolidated Ratio of Earnings to Fixed Charges and Consolidated Ratio of Earnings to Combined Fixed Charges and Preferred Stock Dividends” included in Exhibit 12.1 to our annual report on Form 10-K, as of December 31, 2012.

Net debt to Adjusted EBITDA

Net debt to Adjusted EBITDA is a non-GAAP financial measure that we believe is useful to investors as a supplemental measure in evaluating our leverage.  Net debt is equal to the sum of total debt less cash, cash equivalents, and restricted cash.  See “Adjusted EBITDA” for further information on the calculation of Adjusted EBITDA.

The following table summarizes the calculation of net debt to Adjusted EBITDA as of March 31, 2013, and December 31, 2012 (dollars in thousands):

Adjusted EBITDA (trailing 12 months) $ 397,606 $ 393,124
Net debt to Adjusted EBITDA (trailing 12 months) 7.7x 7.6x

(1)         We believe the Adjusted EBITDA and net debt to Adjusted EBITDA for the three months ended March 31, 2013, and December 31, 2012, annualized, reflect the completion of many development and redevelopment projects and are indicative of the Company’s current operating trends.

Net debt to gross assets (excluding cash and restricted cash)

Net debt to gross assets (excluding cash and restricted cash) is a non-GAAP financial measure that we believe is useful to investors as a supplemental measure in evaluating our leverage.  Net debt is calculated as described in “Net Debt to Adjusted EBITDA.”  Gross assets (excluding cash and restricted cash) are equal to total assets plus accumulated depreciation less cash, cash equivalents, and restricted cash.

The following table summarizes the calculation of net debt to gross assets (excluding cash and restricted cash) as of March 31, 2013, and December 31, 2012 (dollars in thousands):

As of

NOI

NOI is a non-GAAP financial measure equal to income from continuing operations, the most directly comparable GAAP financial measure, plus loss (gain) on early extinguishment of debt, impairment of land parcel, depreciation and amortization, interest expense, and general and administrative expense.  We believe NOI provides useful information to investors regarding our financial condition and results of operations because it reflects primarily those income and expense items that are incurred at the property level.  Therefore, we believe NOI is a useful measure for evaluating the operating performance of our real estate assets.  NOI on a cash basis is NOI on a GAAP basis, adjusted to exclude the effect of straight-line rent adjustments required by GAAP.  We believe that NOI on a cash basis is helpful to investors as an additional measure of operating performance because it eliminates straight-line rent adjustments to rental revenue.

Further, we believe NOI is useful to investors as a performance measure, because when compared across periods, NOI reflects the impact on operations from trends in occupancy rates, rental rates, and operating costs, providing perspective not immediately apparent from income from continuing operations.  NOI excludes certain components from income from continuing operations in order to provide results that are more closely related to the results of operations of our properties.  For example, interest expense is not necessarily linked to the operating performance of a real estate asset and is often incurred at the corporate level rather than at the property level.  In addition, depreciation and amortization, because of historical cost accounting and useful life estimates, may distort operating performance at the property level.  Real estate impairments have been excluded in deriving NOI because we do not consider impairment losses to be property-level operating expenses.  Real estate impairment losses relate to changes in the values of our assets and do not reflect the current operating performance with respect to related revenues or expenses.  Our real estate impairments represent the write-down in the value of the assets to the estimated fair value less cost to sell.  These impairments result from investing decisions and the deterioration in market conditions that adversely impact underlying real estate values.  Our calculation of NOI also excludes charges incurred from changes in certain financing decisions, such as losses on early extinguishment of debt, as these charges often relate to the timing of corporate strategy.  Property operating expenses that are included in determining NOI consist of costs that are related to our operating properties, such as utilities; repairs and maintenance; rental expense related to ground leases; contracted services, such as janitorial, engineering, and landscaping; property taxes and insurance; and property-level salaries.  General and administrative expenses consist primarily of accounting and corporate compensation, corporate insurance, professional fees, office rent, and office supplies that are incurred as part of corporate office management.  NOI presented by us may not be comparable to NOI reported by other equity REITs that define NOI differently.  We believe that in order to facilitate a clear understanding of our operating results, NOI should be examined in conjunction with income from continuing operations as presented in our condensed consolidated statements of income.  NOI should not be considered as an alternative to income from continuing operations as an indication of our performance, or as an alternative to cash flows as a measure of liquidity or a measure of our ability to make distributions.

The following table is a reconciliation of NOI from continuing operations to income from continuing operations and NOI from discontinued operations to income from discontinued operations, the most directly comparable financial measure calculated and presented in accordance with GAAP (in thousands):

Same property NOI

See discussion of Same Properties and reconciliation of NOI to income from continuing operations in “Results of Operations.”

Unencumbered NOI as a percentage of total NOI

Unencumbered NOI as a percentage of total NOI is a non-GAAP financial measure that we believe is useful to investors as a performance measure of our results of operations of our unencumbered real estate assets, as it reflects primarily those income and expense items that are incurred at the unencumbered property level.  We use unencumbered NOI as a percentage of total NOI in order to assess our compliance with our financial covenants under our debt obligations because the measure serves as a proxy for a financial measure under such debt obligations.  Unencumbered NOI is derived from assets classified in continuing operations that are not subject to any mortgage, deed of trust, lien, or other security interest as of the period for which income is presented.  Unencumbered NOI for periods prior to the three months ended March 31, 2013, has been reclassified to conform to current period presentation related to discontinued operations.  See the reconciliation of NOI to income from continuing operations in “Results of Operations.”

The following table summarizes unencumbered NOI as a percentage of total NOI for the three months ended March 31, 2013 and 2012 (dollars in thousands):

Three Months Ended March 31,
2013 2012
Unencumbered net operating income $ 71,402 $ 66,199
Encumbered net operating income 33,754 29,059
Total net operating income $ 105,156 $ 95,258
Unencumbered net operating income as a percentage of total net operating income 68% 69%

Unlevered IRR

We believe Unlevered IRR is a useful supplemental performance measure used by investors to evaluate the performance of a specific real estate investment.  Unlevered IRR is the annualized implied discount rate calculated from the cash flows of a real estate asset over the holding period for such asset.  Unlevered IRR represents the return that equates the present value of all capital invested in a real estate asset to the present value of all cash flows generated by that real estate asset, or the discount rate that provides a net present value of all cash flows related to a real estate asset to zero. Unlevered IRR is calculated based upon the actual timing of cash flows, including among others i) the initial cash purchase price; ii) cash NOI (GAAP NOI excluding the impact of straight-line rents); iii) capital expenditures; iv) leasing costs, and v) the net sales proceeds of each respective real estate asset.  Losses incurred upon sale or non-cash impairment charges recognized during our ownership period are reflected in the unlevered IRR through the net sales proceeds of each real estate asset.  The calculation of unlevered IRR does not include general and administrative costs of the Company or interest expense related to the Company’s financing costs, because they are not directly related or attributable to the operations of the real estate asset.

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate risk

The primary market risk to which we believe we are exposed is interest rate risk, which may result from many factors, including government monetary and tax policies, domestic and international economic and political considerations, and other factors that are beyond our control.

In order to modify and manage the interest rate characteristics of our outstanding debt and to limit the effects of interest rate risks on our operations, we may utilize a variety of financial instruments, including interest rate swap agreements, caps, floors, and other interest rate exchange contracts.  The use of these types of instruments to hedge a portion of our exposure to changes in interest rates carries additional risks, such as counterparty credit risk and the legal enforceability of hedging contracts.

Our future earnings and fair values relating to financial instruments are primarily dependent upon prevalent market rates of interest, such as LIBOR.  However, our interest rate swap agreements are intended to reduce the effects of interest rate changes.  The following table illustrates the effect of a 1% increase/decrease in interest rates, assuming a LIBOR floor of 0%, on our variable rate debt, including our unsecured senior line of credit and unsecured senior bank term loans, after considering the effect of our interest rate swap agreements, secured debt, unsecured senior notes payable, and unsecured senior convertible notes (in thousands):

As of<br> March 31, 2013 As of<br> December 31, 2012
Impact to future earnings due to variable rate debt:
Rate increase of 1% $ (2,527 ) $ (5,870 )
Rate decrease of 1% $ 6,352 $ 1,101
Effect on fair value of secured debt:
Rate increase of 1% $ (33,844 ) $ (37,146 )
Rate decrease of 1% $ 25,547 $ 27,260

These amounts are determined by considering the impact of the hypothetical interest rates on our borrowing cost and our interest rate swap agreements in effect on March 31, 2013.  These analyses do not consider the effects of the reduced level of overall economic activity that could exist in such an environment.  Further, in the event of a change of such magnitude, we would consider taking actions to further mitigate our exposure to the change.  However, because of the uncertainty of the specific actions that would be taken and their possible effects, the sensitivity analyses assume no changes in our capital structure.

Equity price risk

We have exposure to equity price market risk because of our equity investments in certain publicly traded companies and privately held entities.  We classify investments in publicly traded companies as “available for sale” and, consequently, recognize them in the accompanying condensed consolidated balance sheets at fair value, with unrealized gains or losses reported as a component of accumulated other comprehensive income or loss.  Investments in privately held entities are generally accounted for under the cost method because we do not influence any of the operating or financial policies of the entities in which we invest.  For all investments, we recognize other-than-temporary declines in value against earnings in the same period during which the decline in value was deemed to have occurred.  There is no assurance that future declines in value will not have a material adverse impact on our future results of operations.  The following table illustrates the effect that a 10% change in the fair value of our equity investments would have on earnings (in thousands):

As of<br> March 31, 2013 As of<br> December 31, 2012
Equity price risk:
Increase in fair value of 10% $ 12,354 $ 11,505
Decrease in fair value of 10% $ (12,354 ) $ (11,505 )

Foreign currency exchange rate risk

We have exposure to foreign currency exchange rate risk related to our subsidiaries operating in Canada and Asia.  The functional currencies of our foreign subsidiaries are the respective local currencies.  Gains or losses resulting from the translation of our foreign subsidiaries’ balance sheets and statements of income are classified in accumulated other comprehensive income as a separate component of total equity.  Gains or losses will be reflected in our statements of income when there is a sale or partial sale of our investment in these operations or upon a complete or substantially complete liquidation of the investment.  The following table illustrates the effect that a 10% increase or decrease in foreign currency rates relative to the U.S. dollar would have on our earnings, based on our current operating assets outside the U.S. (in thousands):

As of<br> March 31, 2013 As of<br> December 31, 2012
Foreign currency exchange rate risk:
Increase in foreign currency exchange rate of 10% $ (20 ) $ (29 )
Decrease in foreign currency exchange rate of 10% $ 20 $ 29

This sensitivity analysis assumes a parallel shift of all foreign currency exchange rates with respect to the U.S. dollar; however, foreign currency exchange rates do not typically move in such a manner and actual results may differ materially.

Item 4.  CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures

As of March 31, 2013, we had performed an evaluation, under the supervision of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of our disclosure controls and procedures.  These controls and procedures have been designed to ensure that information required for disclosure is recorded, processed, summarized, and reported within the requisite time periods.  Based on our evaluation, the CEO and CFO concluded that our disclosure controls and procedures were effective as of March 31, 2013.

Changes in internal control over financial reporting

There has not been any change in our internal control over financial reporting during the three months ended March 31, 2013, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART IIOTHER INFORMATION

Item 1A. **** RISK FACTORS

In addition to the information set forth in this quarterly report on Form 10-Q, one should also carefully review and consider the information contained in our other reports and periodic filings that we make with the SEC, including, without limitation, the information contained under the caption “Item 1A.  Risk Factors” in our annual report on Form 10-K for the year ended December 31, 2012.  Those risk factors could materially affect our business, financial condition, and results of operations.  The risks that we describe in our public filings are not the only risks that we face.  Additional risks and uncertainties not currently known to us, or that we presently deem to be immaterial, also may materially adversely affect our business, financial condition, and results of operations.

--- ---
(b) Income from continuing operations before noncontrolling interests for the years ended December 31, 2012, 2011, and 2010, includes the gain on sales of land parcels of approximately $1.9 million, $46,000, and $59.4 million, respectively. Pursuant to the presentation and disclosure literature on gains/losses on sales or disposals by real estate investment trusts (“REITs”) and earnings per share required by the Securities and Exchange Commission and the Financial Accounting Standards Board, gains or losses on sales or disposals by a REIT that do not qualify as discontinued operations are classified below income (loss) from discontinued operations in the statements of income and are included in the numerator for the computation of earnings per share for income from continuing operations. The land parcels we sold during the years ended December 31, 2012, 2011, and 2010, did not meet the criteria for classification as discontinued operations because the parcels did not have any significant operations prior to disposition. Accordingly, for the years ended December 31, 2012, 2011, and 2010, we classified the $1.9 million, $46,000, and $59.4 million, respectively, gain on sales of land parcels below income (loss) from discontinued operations, net, in the condensed consolidated statements of income, and included the gain in income from continuing operations for the computation of earnings per share.
(c) For purposes of calculating the consolidated ratio of earnings to fixed charges and consolidated ratio of earnings to combined fixed charges and preferred stock dividends, earnings consist of income from continuing operations before noncontrolling interests and interest expense less noncontrolling interests in income of subsidiaries that have not incurred fixed charges. Fixed charges consist of interest incurred (including amortization of deferred financing costs and capitalized interest).
(d) Ratios for the year ended December 31, 2012, include the effect of losses on early extinguishment of debt aggregating $2.2 million, a preferred stock redemption charge of $6.0 million, impairment of land parcel of $2.1 million, and impairment of real estate of $11.4 million. Excluding the impact of losses on early extinguishment of debt, the preferred stock redemption charge, impairment of land parcel, and the impairment of real estate, the consolidated ratio of earnings to fixed charges and consolidated ratio of earnings to combined fixed charges and preferred stock dividends for the year ended December 31, 2012, were 1.36 and 1.09, respectively.
(e) Ratios for the year ended December 31, 2011, include the effect of loss on early extinguishment of debt aggregating $6.5 million and impairment of real estate of approximately $1.0 million. Excluding the impact of loss on early extinguishment of debt and the impairment of real estate, the consolidated ratio of earnings to fixed charges and consolidated ratio of earnings to combined fixed charges and preferred stock dividends for the year ended December 31, 2011, were 1.56 and 1.26, respectively.
(f) Ratios for the year ended December 31, 2010, include the effect of loss on early extinguishment of debt aggregating $45.2 million. Excluding the impact of loss on early extinguishment of debt, the consolidated ratio of earnings to fixed charges and the consolidated ratio of earnings to combined fixed charges and preferred stock dividends for the year ended December 31, 2010, were 1.77 and 1.46, respectively.
(g) Ratios for the year ended December 31, 2008, include the effect of impairment of real estate aggregating $13.3 million for other-than-temporary declines in the fair value of certain investments. Excluding the impact of impairment of real estate, the consolidated ratio of earnings to fixed charges and the consolidated ratio of earnings to combined fixed charges and preferred stock dividends for the year ended December 31, 2008, were 1.18 and 1.02, respectively.
