SIGNIFICANT BALANCE SHEET MILESTONES

Closed secured construction loan for development project in San Francisco Bay market

In June 2012, we closed a secured construction loan with aggregate commitments of $55 million.  The construction loan matures in June 2017, assuming we exercise our sole option to extend the stated maturity date of June 2015 by one year, twice.  The construction loan will be used to fund the majority of the cost to complete the development of a 100% pre-leased 170,618 rentable square feet life science laboratory building at 259 East Grand Avenue in the San Francisco Bay market.  The construction loan will bear interest at the London Interbank Offered Rate (“LIBOR”) or the base rate specified in the construction loan agreement, defined as the higher of either the prime rate being offered by our lender or the federal funds rate in effect on the day of borrowing (“Base Rate”), plus in either case a specified margin of 1.50% for LIBOR borrowings or 0.25% for Base Rate borrowings.  As of June 30, 2012, $55 million of commitments were available.

Debut 4.60% unsecured senior notes payable offering

In February 2012, we completed the issuance of our 4.60% unsecured senior notes payable due in February 2022.  Net proceeds of approximately $544.6 million were used to repay certain outstanding variable rate bank debt, including the entire $250 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.

Amendment of $1.5 billion unsecured senior line of credit

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 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.

6.45% series E preferred stock offering

In March 2012, we completed a public offering of 5,200,000 shares of our 6.45% series E cumulative redeemable preferred stock (“Series E Preferred Stock”).  The shares were issued at a price of $25.00 per share, resulting in net proceeds of approximately $124.9 million (after deducting underwriters’ discounts and other offering costs).  The proceeds were initially used to reduce the outstanding borrowings under our unsecured senior line of credit.  We then borrowed funds under our unsecured senior line of credit to redeem our 8.375% series C cumulative redeemable preferred stock (“Series C Preferred Stock”) in April 2012.  The dividends on our Series E Preferred Stock are cumulative and accrue from the date of original issuance.  We pay dividends quarterly in arrears at an annual rate of 6.45%, or $1.6125 per share.  Our Series E Preferred Stock has no stated maturity date, is not subject to any sinking fund or mandatory redemption provisions, and is not redeemable before March 15, 2017, except to preserve our status as a real estate investment trust (“REIT”).  On and after March 15, 2017, we may, at our option, redeem the Series E Preferred Stock, in whole or in part, at any time for cash at a redemption price of $25.00 per share, plus any accrued and unpaid dividends on the Series E Preferred Stock up to, but excluding, the redemption date.  In addition, upon the occurrence of a change of control, we may, at our option, redeem the Series E Preferred Stock, in whole or in part within 120 days after the first date on which such change of control occurred, by paying $25.00 per share, plus any accrued and unpaid dividends up to, but excluding, the date of redemption.  Investors in our Series E Preferred Stock generally have no voting rights.

8.375% series C preferred stock redemption

In April 2012, we redeemed all 5,185,500 outstanding shares of our Series C Preferred Stock at a price equal to $25.00 per share, and paid $0.5234375 per share, representing accumulated and unpaid dividends to the redemption date on such shares.  We recognized a charge of approximately $6.0 million to net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders during the six months ended June 30, 2012, related to the write-off of original issuance costs of the Series C Preferred Stock.

Establishment of “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 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.  In June 2012, we sold an aggregate of 573,686 shares of common stock for gross proceeds of approximately $40.5 million at an average stock price of $70.64 and net proceeds of approximately $39.9 million.  As of June 30, 2012, approximately $209.5 million of our common stock remained available for issuance under the “at the market” common stock offering program.

(2)        In March 2012, we sold one-half of our 55% interest in a land parcel supporting a 414,000 rentable square feet project for approximately $31 million (including closing costs), or approximately $275 per rentable square foot. See discussion below.

(3)        Amount represents aggregate contract sales prices for three assets held for sale. Includes one property sold in July 2012 to a tenant occupying 100% of the property, at a price of approximately $8.0 million, or approximately $222 per square foot, resulting in a gain of approximately $1.4 million. The remaining two properties aggregating 196,029 future developable square feet are targeted for sale at an aggregate price of approximately $14.2 million, or approximately $72 per developable square foot.  Net book values of the three properties totaled approximately $19.4 million as of June 30, 2012.

(4)        Represents estimate of proceeds from future dispositions that have not met the criteria for classification as discontinued operations.

Sale of land parcel

In March 2012, we contributed our 55% ownership interest in a land parcel supporting a future 414,000 rentable square feet building in the Longwood Medical Area of the Greater Boston market to a newly formed joint venture (the “Restated JV”) with National Development and Charles River Realty Investors, and admitted as a 50% member, Clarion Partners, LLC, resulting in a reduction of our ownership interest from 55% to 27.5%.  The transfer of one-half of our 55% ownership interest in this real estate venture to Clarion Partners, LLC, was accounted for as an in-substance partial sale of an interest in the underlying real estate.  In connection with the sale of one-half of our 55% ownership interest in the land parcel, we received a special distribution of approximately $22.3 million, which included the recognition of a $1.9 million gain on sale of land and approximately $5.4 million from our share of loan refinancing proceeds.  The land parcel we sold in March 2012 did not meet the criteria for discontinued operations since the parcel did not have any significant operations prior to disposition. Pursuant to the presentation and disclosure literature on gains/losses on sales or disposals by REITs required by the Securities and Exchange Commission (“SEC”), gains or losses on sales or disposals by a REIT that do not qualify as discontinued operations are classified below income from discontinued operations in the income statement.  Accordingly, we classified the $1.9 million gain on sale of land below income from discontinued operations, net, in the condensed consolidated statements of income.  Our 27.5% share of the land was sold at approximately $31 million (including closing costs), or approximately $275 per rentable square foot.  Upon formation of the Restated JV, the existing $38.4 million secured loan was refinanced with a seven-year (including two one-year extension options) non-recourse $213 million secured construction loan with initial loan proceeds of $50 million.  As of June 30, 2012, the outstanding balance on the construction loan was $51.1 million.  We do not expect our share of capital contributions through the completion of the project to exceed the approximate $22.3 million in net proceeds received in this transaction.  Construction of this $350 million project commenced in April 2012, with an initial occupancy date in the fourth quarter of 2014, and the project is 37% pre-leased to Dana-Farber Cancer Institute, Inc.  In addition, Dana-Farber Cancer Institute, Inc. has an option to an additional two floors approximating 99,000 rentable square feet, or 24% of the total rentable square feet of the project.  We expect to earn development and other fees of approximately $3.5 million through 2015, and recurring annual property management fees thereafter.  For the three and six months ended June 30, 2012, we recognized approximately $0.2 million of development fees.  These fees are classified in other income in the condensed consolidated statements of income.

VALUE-ADDED OPPORTUNITIES AND EXTERNAL GROWTH

Development and redevelopment

During the three and six months ended June 30, 2012, we executed leases aggregating 169,000 and 563,000 rentable square feet, respectively, related to our development and redevelopment projects.

In June 2012, we completed the redevelopment of 3530/3550 John Hopkins Court, a combined 98,320 rentable square feet multi-tenant campus located in the San Diego market, which is 100% leased to (1) Genomics Institute of the Novartis Research Foundation, a non-profit research institute, and (2) a leading industrial biotechnology company.  The stabilized yield on cost on a cash and GAAP basis for this project was approximately 8.9% and 9.1%, respectively.  Stabilized yield on cost is calculated as the quotient of net operating income and our investment in the property at stabilization (“Stabilized Yield”).

In April 2012, we completed the development of a 26,426 rentable square feet building located in the Canada market, which is 100% leased to GlaxoSmithKline plc.  The Stabilized Yield on a cash and GAAP basis for this project was approximately 7.7% and 8.3%, respectively.

In April 2012, we commenced ground-up development of 360 Longwood Avenue, our 414,000 rentable square feet unconsolidated joint venture development project located in the Longwood Medical Area of the Greater Boston Market, which is 37% pre-leased to the Dana-Farber Cancer Institute, Inc.  We expect to achieve an unlevered Stabilized Yield on a cash and GAAP basis in a range from 8.1% to 8.5% and 8.7% to 9.1%, respectively.  Funding for this project is primarily provided by capital from our joint venture partner and a $213.2 million non-recourse secured construction loan.  Additionally, our share of the future funding is expected to be less than the $22.3 million distribution we received in March 2012, upon admittance of the new partner and refinancing of the project.

In January 2012, we commenced a ground-up development of a 170,618 rentable square feet single tenant building at 259 East Grand Avenue in the San Francisco Bay market which is 100% pre-leased to Onyx Pharmaceuticals Inc.  We expect to achieve a Stabilized Yield on both a cash and GAAP basis for this property in a range from 7.8% to 8.2%.  Funding for this project will be primarily provided by the $55 million secured construction loan we closed in June 2012.

Acquisitions

In April 2012, we acquired 3013/3033 Science Park Road, which consists of two life science laboratory buildings aggregating 176,500 rentable square feet, for approximately $13.7 million.  The property was 100% leased on a short-term basis through July 2012, and thereafter, we expect to redevelop approximately 105,000 rentable square feet.  The remaining square footage will be classified as future developable square feet.  We expect to provide an estimate of our Stabilized Yields in the future upon commencement of development/redevelopment activity.

Net operating income, net income, and FFO for the three months ended December 31, 2012

As of June 30, 2012, we had approximately $290.3 million and $275.1 million of construction in progress related to our six North American development and 10 North American redevelopment projects, respectively. The completion of these projects, along with recently delivered projects, certain future projects, and contributions from same properties, are expected to contribute significant increases in rental income, net operating income, and cash flows.  Net operating income is projected to increase quarter to quarter, from $103.8 million for the three months ended June 30, 2012 (before the realized gain of $5.8 million on an equity investment primarily related to one non-tenant life science entity) to a range from $110.5 million to $112.5 million for the three months ended December 31, 2012.  Operating performance assumptions related to the completion of our North America development and redevelopment projects, including the timing of initial occupancy, stabilization dates, and stabilization yields, are included on page 8.  Certain key assumptions regarding our projections, including the impact of various development and redevelopment projects, are included in the tables on the preceding page and below.

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 projections for general and administrative expenses, capitalization of interest, and interest expense, net, are included in the table on the preceding page and below.  Our projections of net operating income 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, 2011.  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 net operating income is a key performance indicator and is useful to investors as a performance measure because, when compared across periods, net operating income 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.

Three Months Ended December 31, 2012 (in millions, except per share amounts) Reported on July 30, 2012 Reported on May 1, 2012
Net operating income $110.5 – $112.5 $111.0 – $113.0

(NYSE: ARE), a self-administered and self-managed REIT, is the largest and leading investment-grade REIT focused principally on owning, operating, redeveloping, developing and acquiring high-quality, sustainable real estate for the broad and diverse life science industry.  Founded in 1994, Alexandria was the first REIT to identify and pursue the laboratory niche and has since had the first-mover advantage in every core life science cluster location including Greater Boston, San Francisco Bay, San Diego, New York City, Seattle, Suburban Washington, D.C., and Research Triangle Park. Alexandria’s high-credit client tenants span the life science industry, including renowned academic and medical institutions, multinational pharmaceutical companies, public and private biotechnology entities, United States government research agencies, medical device companies, clean technology companies, venture capital firms, and life science product and service companies.

Non-GAAP Measures

(Unaudited)

Funds from operations and funds from operations, as adjusted

GAAP basis accounting for real estate assets utilizes historical cost accounting and assumes 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 the National Association of Real Estate Investment Trusts (“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 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 April 2002 White Paper and related implementation guidance (“NAREIT White Paper”). The NAREIT White Paper defines FFO as net income (computed in accordance with GAAP), excluding gains from sales and real estate impairment losses, plus real estate related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures.  We compute FFO, as adjusted as FFO calculated in accordance with the NAREIT White Paper, plus losses from early extinguishment of debt and preferred stock redemption charges, less realized gain on equity investment primarily related to one non-tenant life science entity, and the amount of such items which are 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 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 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-incremental revenue-enhancing capital expenditures, tenant improvements, and leasing commissions (excludes 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 which, although capitalized and included 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 stock-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 of 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 only intended 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.

Net operating income

Net operating income is a non-GAAP financial measure equal to income from continuing operations, the most directly comparable GAAP financial measure, plus loss on early extinguishment of debt, depreciation and amortization, interest expense, and general and administrative expense.  We believe net operating income 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 net operating income is a useful measure for evaluating the operating performance of our real estate assets.  Net operating income on a cash basis is net operating income on a GAAP basis, adjusted to exclude the effect of straight-line rent adjustments required by GAAP.  We believe that net operating income 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 net operating income is useful to investors as a performance measure because, when compared across periods, net operating income 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.  Net operating income 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.  Net operating income presented by us may not be comparable to net operating income reported by other equity REITs that define net operating income differently.  We believe that in order to facilitate a clear understanding of our operating results, net operating income should be examined in conjunction with income from continuing operations as presented in our condensed consolidated statements of income.  Net operating income 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 our ability to make distributions.

Company Profile

June 30, 2012

The Company

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

Unique Niche Strategy

Alexandria’s primary business objective is to maximize stockholder value by providing its 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 adjacent to life science entities driving growth and technological advances within each cluster.  These adjacency locations are characterized by high barriers to entry and exit, limited supply of available space, and represent highly desirable locations for tenancy by life science entities.  Alexandria’s strategy also includes drawing on its 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 opportunities.  The Company was founded in 1994 by Jerry M. Sudarsky and Joel S. Marcus.  The Company executed its initial public offering in 1997.

Management

Alexandria’s executive and senior management team is highly experienced in the REIT industry (uniquely with life science and real estate development, construction, operations, ownership, expertise, and experience) and is the most accomplished team focused on providing high-quality, environmentally sustainable real estate, technical infrastructure, and unique expertise to the broad and diverse life science industry.  Our deep and talented team has decades of life science industry experience.  Our management team also includes highly experienced regional market directors averaging over 20 years of real estate experience, including approximately 10 years with Alexandria.  We believe that our expertise, experience, reputation, and key life science relationships provide Alexandria significant competitive advantages in attracting new business opportunities.

Client Tenant Base

The quality, diversity, breadth, and depth of our significant relationships with our life science client tenants provide the Company with solid and stable cash flows.  Investment-grade tenants represented 48% of Alexandria’s annualized base rent as of June 30, 2012.  As of June 30, 2012, our multinational pharmaceutical client tenants represented approximately 25.3% of our annualized base rent, led by Bristol-Myers Squibb Company, Eli Lilly and Company, GlaxoSmithKline plc, Novartis AG, Pfizer Inc., and Roche Holding Ltd; revenue-producing life science product and service, medical device, and clean technology companies represented approximately 22.6%, led by Illumina, Inc., Laboratory Corporation of America Holdings, Monsanto Company, Qiagen N.V., and Quest Diagnostics Incorporated; non-profit, renowned medical and research institutions, and government agencies represented approximately 17.2% and included Fred Hutchinson Cancer Research Center, Massachusetts Institute of Technology, The Regents of the University of California, Sanford-Burnham Medical Research Institute, The Scripps Research Institute, the United States Government, and University of Washington; public biotechnology companies represented approximately 16.8% and included Amgen Inc., Biogen Idec Inc., Celgene Corporation, and Gilead Sciences, Inc.; private biotechnology companies represented approximately 13.8% and included high-quality, leading-edge companies with blue-chip venture and institutional investors, including FibroGen, Inc., FORMA Therapeutics, Inc., and Quanticel Pharmaceuticals, Inc.; and the remaining approximately 4.3% consisted of traditional office tenants.  Alexandria’s strong life science underwriting skills, long-term life science industry relationships, and sophisticated management with both real estate and life science operating expertise positively distinguish the Company from all other publicly traded real estate investment trusts and real estate companies.

SIGNIFICANT BALANCE SHEET MILESTONES

Closed secured construction loan for development project in San Francisco Bay market

In June 2012, we closed a secured construction loan with aggregate commitments of $55 million.  The construction loan matures in June 2017, assuming we exercise our sole option to extend the stated maturity date of June 2015 by one year, twice.  The construction loan will be used to fund the majority of the cost to complete the development of a 100% pre-leased 170,618 rentable square feet life science laboratory building at 259 East Grand Avenue in the San Francisco Bay market.  The construction loan will bear interest at the London Interbank Offered Rate (“LIBOR”) or the base rate specified in the construction loan agreement, defined as the higher of either the prime rate being offered by our lender or the federal funds rate in effect on the day of borrowing (“Base Rate”), plus in either case a specified margin of 1.50% for LIBOR borrowings or 0.25% for Base Rate borrowings.  As of June 30, 2012, $55 million of commitments were available.

Debut 4.60% unsecured senior notes payable offering

In February 2012, we completed the issuance of our 4.60% unsecured senior notes payable due in February 2022.  Net proceeds of approximately $544.6 million were used to repay certain outstanding variable rate bank debt, including the entire $250 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.

Amendment of $1.5 billion unsecured senior line of credit

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 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.

6.45% series E preferred stock offering

In March 2012, we completed a public offering of 5,200,000 shares of our 6.45% series E cumulative redeemable preferred stock (“Series E Preferred Stock”).  The shares were issued at a price of $25.00 per share, resulting in net proceeds of approximately $124.9 million (after deducting underwriters’ discounts and other offering costs).  The proceeds were initially used to reduce the outstanding borrowings under our unsecured senior line of credit.  We then borrowed funds under our unsecured senior line of credit to redeem our 8.375% series C cumulative redeemable preferred stock (“Series C Preferred Stock”) in April 2012.  The dividends on our Series E Preferred Stock are cumulative and accrue from the date of original issuance.  We pay dividends quarterly in arrears at an annual rate of 6.45%, or $1.6125 per share.  Our Series E Preferred Stock has no stated maturity date, is not subject to any sinking fund or mandatory redemption provisions, and is not redeemable before March 15, 2017, except to preserve our status as a real estate investment trust (“REIT”).  On and after March 15, 2017, we may, at our option, redeem the Series E Preferred Stock, in whole or in part, at any time for cash at a redemption price of $25.00 per share, plus any accrued and unpaid dividends on the Series E Preferred Stock up to, but excluding, the redemption date.  In addition, upon the occurrence of a change of control, we may, at our option, redeem the Series E Preferred Stock, in whole or in part within 120 days after the first date on which such change of control occurred, by paying $25.00 per share, plus any accrued and unpaid dividends up to, but excluding, the date of redemption.  Investors in our Series E Preferred Stock generally have no voting rights.

8.375% series C preferred stock redemption

In April 2012, we redeemed all 5,185,500 outstanding shares of our Series C Preferred Stock at a price equal to $25.00 per share, and paid $0.5234375 per share, representing accumulated and unpaid dividends to the redemption date on such shares.  We recognized a charge of approximately $6.0 million to net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders during the six months ended June 30, 2012, related to the write-off of original issuance costs of the Series C Preferred Stock.

Establishment of “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 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.  In June 2012, we sold an aggregate of 573,686 shares of common stock for gross proceeds of approximately $40.5 million at an average stock price of $70.64 and net proceeds of approximately $39.9 million.  As of June 30, 2012, approximately $209.5 million of our common stock remained available for issuance under the “at the market” common stock offering program.

(2)             In March 2012, we sold one-half of our 55% interest in a land parcel supporting a 414,000 rentable square feet project for approximately $31 million (including closing costs), or approximately $275 per rentable square foot. See discussion below.

(3)             Amount represents aggregate contract sales prices for three assets held for sale. Includes one property sold in July 2012 to a tenant occupying 100% of the property, at a price of approximately $8.0 million, or approximately $222 per square foot, resulting in a gain of approximately $1.4 million. The remaining two properties aggregating 196,029 future developable square feet are targeted for sale at an aggregate price of approximately $14.2 million, or approximately $72 per developable square foot.  Net book values of the three properties totaled approximately $19.4 million as of June 30, 2012.

(4)             Represents estimate of proceeds from future dispositions that have not met the criteria for classification as discontinued operations.

Sale of land parcel

In March 2012, we contributed our 55% ownership interest in a land parcel supporting a future 414,000 rentable square feet building in the Longwood Medical Area of the Greater Boston market to a newly formed joint venture (the “Restated JV”) with National Development and Charles River Realty Investors, and admitted as a 50% member, Clarion Partners, LLC, resulting in a reduction of our ownership interest from 55% to 27.5%.  The transfer of one-half of our 55% ownership interest in this real estate venture to Clarion Partners, LLC, was accounted for as an in-substance partial sale of an interest in the underlying real estate.  In connection with the sale of one-half of our 55% ownership interest in the land parcel, we received a special distribution of approximately $22.3 million, which included the recognition of a $1.9 million gain on sale of land and approximately $5.4 million from our share of loan refinancing proceeds.  The land parcel we sold in March 2012 did not meet the criteria for discontinued operations since the parcel did not have any significant operations prior to disposition. Pursuant to the presentation and disclosure literature on gains/losses on sales or disposals by REITs required by the Securities and Exchange Commission (“SEC”), gains or losses on sales or disposals by a REIT that do not qualify as discontinued operations are classified below income from discontinued operations in the income statement.  Accordingly, we classified the $1.9 million gain on sale of land below income from discontinued operations, net, in the condensed consolidated statements of income.  Our 27.5% share of the land was sold at approximately $31 million (including closing costs), or approximately $275 per rentable square foot.  Upon formation of the Restated JV, the existing $38.4 million secured loan was refinanced with a seven-year (including two one-year extension options) non-recourse $213 million secured construction loan with initial loan proceeds of $50 million.  As of June 30, 2012, the outstanding balance on the construction loan was $51.1 million.  We do not expect our share of capital contributions through the completion of the project to exceed the approximate $22.3 million in net proceeds received in this transaction.  Construction of this $350 million project commenced in April 2012, with an initial occupancy date in the fourth quarter of 2014, and the project is 37% pre-leased to Dana-Farber Cancer Institute, Inc.  In addition, Dana-Farber Cancer Institute, Inc. has an option to an additional two floors approximating 99,000 rentable square feet, or 24% of the total rentable square feet of the project.  We expect to earn development and other fees of approximately $3.5 million through 2015, and recurring annual property management fees thereafter.  For the three and six months ended June 30, 2012, we recognized approximately $0.2 million of development fees.  These fees are classified in other income in the condensed consolidated statements of income.

VALUE-ADDED OPPORTUNITIES AND EXTERNAL GROWTH

Development and redevelopment

During the three and six months ended June 30, 2012, we executed leases aggregating 169,000 and 563,000 rentable square feet, respectively, related to our development and redevelopment projects.

In June 2012, we completed the redevelopment of 3530/3550 John Hopkins Court, a combined 98,320 rentable square feet multi-tenant campus located in the San Diego market, which is 100% leased to (1) Genomics Institute of the Novartis Research Foundation, a non-profit research institute, and (2) a leading industrial biotechnology company.  The stabilized yield on cost on a cash and GAAP basis for this project was approximately 8.9% and 9.1%, respectively.  Stabilized yield on cost is calculated as the quotient of net operating income and our investment in the property at stabilization (“Stabilized Yield”).

In April 2012, we completed the development of a 26,426 rentable square feet building located in the Canada market, which is 100% leased to GlaxoSmithKline plc.  The Stabilized Yield on a cash and GAAP basis for this project was approximately 7.7% and 8.3%, respectively.

In April 2012, we commenced ground-up development of 360 Longwood Avenue, our 414,000 rentable square feet unconsolidated joint venture development project located in the Longwood Medical Area of the Greater Boston Market, which is 37% pre-leased to the Dana-Farber Cancer Institute, Inc.  We expect to achieve an unlevered Stabilized Yield on a cash and GAAP basis in a range from 8.1% to 8.5% and 8.7% to 9.1%, respectively.  Funding for this project is primarily provided by capital from our joint venture partner and a $213.2 million non-recourse secured construction loan.  Additionally, our share of the future funding is expected to be less than the $22.3 million distribution we received in March 2012, upon admittance of the new partner and refinancing of the project.

In January 2012, we commenced a ground-up development of a 170,618 rentable square feet single tenant building at 259 East Grand Avenue in the San Francisco Bay market which is 100% pre-leased to Onyx Pharmaceuticals Inc.  We expect to achieve a Stabilized Yield on both a cash and GAAP basis for this property in a range from 7.8% to 8.2%.  Funding for this project will be primarily provided by the $55 million secured construction loan we closed in June 2012.

Acquisitions

In April 2012, we acquired 3013/3033 Science Park Road, which consists of two life science laboratory buildings aggregating 176,500 rentable square feet, for approximately $13.7 million.  The property was 100% leased on a short-term basis through July 2012, and thereafter, we expect to redevelop approximately 105,000 rentable square feet.  The remaining square footage will be classified as future developable square feet.  We expect to provide an estimate of our Stabilized Yields in the future upon commencement of development/redevelopment activity.

Net operating income, net income, and FFO for the three months ended December 31, 2012

As of June 30, 2012, we had approximately $290.3 million and $275.1 million of construction in progress related to our six North American development and 10 North American redevelopment projects, respectively. The completion of these projects, along with recently delivered projects, certain future projects, and contributions from same properties, are expected to contribute significant increases in rental income, net operating income, and cash flows.  Net operating income is projected to increase quarter to quarter, from $103.8 million for the three months ended June 30, 2012 (before the realized gain of $5.8 million on an equity investment primarily related to one non-tenant life science entity) to a range from $110.5 million to $112.5 million for the three months ended December 31, 2012.  Operating performance assumptions related to the completion of our North America development and redevelopment projects, including the timing of initial occupancy, stabilization dates, and stabilization yields, are included on page 8.  Certain key assumptions regarding our projections, including the impact of various development and redevelopment projects, are included in the tables on the preceding page and below.

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 projections for general and administrative expenses, capitalization of interest, and interest expense, net, are included in the table on the preceding page and below.  Our projections of net operating income 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, 2011.  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 net operating income is a key performance indicator and is useful to investors as a performance measure because, when compared across periods, net operating income 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.

Three Months Ended December 31, 2012 (in millions, except per share amounts) Reported on July 30, 2012 Reported on May 1, 2012
Net operating income $110.5 – $112.5 $111.0 – $113.0

Non-GAAP Measures

(Unaudited)

Funds from operations and funds from operations, as adjusted

GAAP basis accounting for real estate assets utilizes historical cost accounting and assumes 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 the National Association of Real Estate Investment Trusts (“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 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 April 2002 White Paper and related implementation guidance (“NAREIT White Paper”). The NAREIT White Paper defines FFO as net income (computed in accordance with GAAP), excluding gains from sales and real estate impairment losses, plus real estate related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures.  We compute FFO, as adjusted as FFO calculated in accordance with the NAREIT White Paper, plus losses from early extinguishment of debt and preferred stock redemption charges, less realized gain on equity investment primarily related to one non-tenant life science entity, and the amount of such items which are 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 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 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-incremental revenue-enhancing capital expenditures, tenant improvements, and leasing commissions (excludes 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 which, although capitalized and included 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 stock-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 of 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 only intended 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.

Net operating income

Net operating income is a non-GAAP financial measure equal to income from continuing operations, the most directly comparable GAAP financial measure, plus loss on early extinguishment of debt, depreciation and amortization, interest expense, and general and administrative expense.  We believe net operating income 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 net operating income is a useful measure for evaluating the operating performance of our real estate assets.  Net operating income on a cash basis is net operating income on a GAAP basis, adjusted to exclude the effect of straight-line rent adjustments required by GAAP.  We believe that net operating income 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 net operating income is useful to investors as a performance measure because, when compared across periods, net operating income 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.  Net operating income 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.  Net operating income presented by us may not be comparable to net operating income reported by other equity REITs that define net operating income differently.  We believe that in order to facilitate a clear understanding of our operating results, net operating income should be examined in conjunction with income from continuing operations as presented in our condensed consolidated statements of income.  Net operating income 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 our ability to make distributions.

Non-income-producing real estate assets as a percentage of gross investments in real estate

As of June 30, 2012, approximately 25% of our gross investments in real estate represents non-income-producing assets (land, preconstruction, development, redevelopment, properties in Asia, and investment in unconsolidated real estate entity).  Our active development and redevelopment projects represent 9% of gross investments in real estate, a significant amount of which is pre-leased and expected to be delivered over the next one to seven quarters.  Over the next few years, we may also identify certain land parcels for potential sale.  Over time, our goal is to reduce non-income-producing assets to 15% or less of our gross investments in real estate.

Investment in Unconsolidated Real Estate Entity and Future Value-Added Projects in North America June 30, 2012

(Tabular dollar amounts in thousands)

(Unaudited)

Investment in unconsolidated real estate entity

In March 2012, we contributed our 55% ownership interest in a land parcel supporting a future 414,000 rentable square feet building in the Longwood Medical Area of the Greater Boston market to a newly formed joint venture (the “Restated JV”) with National Development and Charles River Realty Investors, and admitted as a 50% member, Clarion Partners, LLC, resulting in a reduction of our ownership interest from 55% to 27.5%.  The transfer of one-half of our 55% ownership interest in this real estate venture to Clarion Partners, LLC, was accounted for as an in-substance partial sale of an interest in the underlying real estate.  Upon formation of the Restated JV, the existing $38.4 million secured loan was refinanced with a seven-year (including two one-year extension options) non-recourse $213 million secured construction loan with initial loan proceeds of $50 million.  As of June 30, 2012, the outstanding balance on the construction loan was $51.1 million.  We do not expect our share of capital contributions through the completion of the project to exceed the approximate $22.3 million in net proceeds received in this transaction.  Construction of this $350 million project commenced in April 2012, with an initial occupancy date in the fourth quarter of 2014, the project is 37% pre-leased to Dana-Farber Cancer Institute, Inc.  In addition, Dana-Farber Cancer Institute, Inc. has an option to an additional two floors approximating 99,000 rentable square feet, or 24% of the total rentable square feet of the project.  We expect to earn development and other fees of approximately $3.5 million through 2015, and recurring annual property management fees thereafter.  For the three and six months ended June 30, 2012, we recognized approximately $0.2 million of development fees.  These fees are classified in other income in the condensed consolidated statements of income.  As of June 30, 2012, key information regarding the unconsolidated real estate entity in the Greater Boston market was as follows (dollars in thousands):

The joint venture has entered into an interest rate hedge agreement to cap LIBOR at a maximum of 3.50%. The notes carry a maturity date of April 1, 2019, assuming the joint venture exercises its option to extend the stated maturity date of April 1, 2017 by one year, twice.

This section contains additional information for sections throughout this supplemental information package as well as explanations of certain non-GAAP financial measures and the reasons why we use these supplemental measures of performance.  Additional detail can be found in our most recent annual report on Form 10-K and subsequent quarterly reports on Form 10-Q, as well as other documents filed with or furnished to the SEC from time to time.

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 (“Adjusted EBITDA”) to assess the performance of our core operations, for financial and operational decision-making, and as a supplemental or additional means to evaluate 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 land parcels, gains or losses on sales of real estate, and impairments.  We believe Adjusted EBITDA provides investors relevant and useful information because it permits 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 land parcels, gains or losses on sales of real estate, and impairments.  By excluding interest expense, EBITDA and Adjusted EBITDA 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 stock-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 of 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 early extinguishment of debt, gains or losses on sales of land parcels, gains or losses on sales of real estate, and impairments, provides useful information by excluding certain items that are not representative of our core operating results.  These items are not related to core operations, dependent upon historical costs, and subject to judgmental valuation inputs and the timing of our decisions. EBITDA and Adjusted EBITDA have limitations as measures of our performance. EBITDA and Adjusted EBITDA do not reflect our historical cash expenditures or future cash requirements for capital expenditures or contractual commitments.  While EBITDA and Adjusted EBITDA are relevant and widely used measures of performance, they do not represent net income or cash flow 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 and Adjusted EBITDA 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 and Adjusted EBITDA:

Adjusted funds from operations

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-incremental revenue-enhancing capital expenditures, tenant improvements, and leasing commissions (excludes 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 which, although capitalized and included 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 stock-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 of 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 only intended 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.

Annualized base rent

Annualized base rent means the annualized fixed base rental amount in effect as of June 30, 2012, related to our operating rentable square feet (using rental revenue computed on a straight-line basis in accordance with GAAP).

Capitalized interest

A key component of our business model is our value-added development and redevelopment programs.  These programs are focused on providing high-quality generic life science laboratory space to meet the real estate requirements of and are reusable by various life science industry tenants.  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 consist of the ground-up development of generic life science laboratory facilities.  Redevelopment projects consist of the permanent change in use of office, warehouse, and shell space into generic life science laboratory space, including the conversion of single-tenancy space to multi-tenancy space or vice versa.  We also have certain significant value-added projects undergoing important and substantial preconstruction activities to bring these assets to their intended use.  These critical activities add significant value and are required for the construction of buildings. The projects will provide high-quality facilities for the life science industry and are expected to generate significant revenue and cash flows for the Company.  In accordance with GAAP, we capitalize project costs clearly related to the construction, development, and redevelopment as a cost of the project. Indirect project costs such as construction administration, legal fees, and office costs that clearly relate to projects under construction, development, and redevelopment are also capitalized as a cost of the project.  We capitalize project costs only during periods in which activities necessary to prepare an asset for its intended use are in progress.  We also 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 is incurred.  Additionally, should activities necessary to prepare an asset for its intended use cease, interest, taxes, insurance, and certain other direct project costs related to these assets would be expensed as incurred.

Cash interest

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.

Construction in progress/current value-added projects

Active development/active redevelopment projects

A key component of our business model is our value-added development and redevelopment programs.  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 consist of the ground-up development of generic and reusable life science laboratory facilities.  We generally will not commence new development projects for aboveground vertical construction of new life science laboratory space without first securing pre-leasing for such space.  Redevelopment projects consist of the permanent change in use of office, warehouse, and shell space into generic life science laboratory space, including the conversion of single-tenancy space to multi-tenancy space or vice versa.

Generic infrastructure/building improvement projects

Generic infrastructure/building improvement projects include revenue-enhancing capital spending, non-revenue-enhancing capital expenditures, and tenant improvements.

Dividend payout ratio

Dividend payout ratio (common stock) is the ratio of the absolute dollar amount of dividends on our common stock (shares of common stock outstanding on the respective record date multiplied by the related dividend per share) to FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders on a diluted basis, as adjusted.

Dividend yield

Dividend yield for the quarter represents the annualized quarter dividend divided by the closing common stock price at the end of the quarter.

Funds from operations and funds from operations, as adjusted

GAAP basis accounting for real estate assets utilizes historical cost accounting and assumes 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 the National Association of Real Estate Investment Trusts (“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 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 April 2002 White Paper and related implementation guidance (“NAREIT White Paper”). The NAREIT White Paper defines FFO as net income (computed in accordance with GAAP), excluding gains from sales and real estate impairment losses, plus real estate related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures.  We compute FFO, as adjusted as FFO calculated in accordance with the NAREIT White Paper, plus losses from early extinguishment of debt and preferred stock redemption charges, less realized gain on equity investment primarily related to one non-tenant life science entity, and the amount of such items which are 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 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.

Future value-added projects

Land held for future development

All preconstruction efforts have been advanced to appropriate stages and no further preconstruction activities are ongoing and therefore, interest, property taxes, and other costs related to these assets are expensed as incurred.  We generally will not commence new development projects for aboveground vertical construction of new life science laboratory space without first securing pre-leasing for such space.

Land undergoing preconstruction activities (additional CIP)

Preconstruction activities include Building Information Modeling (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.  Our objective with preconstruction is to reduce the time it takes to deliver projects to prospective tenants.  Project costs are capitalized as a cost of the project during periods when activities necessary to prepare an asset for its intended use are in progress.  We generally will not commence ground-up development of any parcels undergoing preconstruction activities without first securing pre-leasing for such space.  If vertical aboveground construction is not initiated at completion of preconstruction activities, the land parcel will be classified as land held for future development.  The two largest projects included in preconstruction consist of our 1.6 million developable square feet at Alexandria Center™ at Kendall Square in East Cambridge, Massachusetts, and our 407,000 developable square foot site for the second tower at Alexandria Center™ for Life Science – New York City.

Future redevelopment

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

Gross assets (excluding cash and restricted cash)

Gross assets (excluding cash and restricted cash) are equal to total assets plus accumulated depreciation, less cash, cash equivalents, and restricted cash.

Interest coverage ratio

Interest coverage ratio is the ratio of Adjusted EBITDA to cash interest. This ratio is useful to investors as an indicator of our ability to service our cash interest obligations.  See fixed charge coverage ratio for calculation of cash interest.  The following table summarizes the calculation of the interest coverage ratio:

**** Three Months Ended
**** 6/30/12 3/31/12 12/31/11 9/30/11 6/30/11
Adjusted EBITDA $ 100,792 $ 94,459 $ 94,491 $ 94,292 $ 95,242
Cash interest $ 31,423 $ 28,671 $ 27,792 $ 28,045 $ 28,121
Interest coverage ratio – quarter annualized 3.2x 3.3x 3.4x 3.4x 3.4x
Interest coverage ratio – trailing 12 months 3.3x 3.4x 3.4x 3.3x 3.2x

Net debt

Net debt is equal to the sum of total debt less cash, cash equivalents, and restricted cash.

Net operating income

Net operating income is a non-GAAP financial measure equal to income from continuing operations, the most directly comparable GAAP financial measure, plus loss on early extinguishment of debt, depreciation and amortization, interest expense, and general and administrative expense.  We believe net operating income 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 net operating income is a useful measure for evaluating the operating performance of our real estate assets.  Net operating income on a cash basis is net operating income on a GAAP basis, adjusted to exclude the effect of straight-line rent adjustments required by GAAP.  We believe that net operating income 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 net operating income is useful to investors as a performance measure because, when compared across periods, net operating income 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.  Net operating income 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.  Net operating income presented by us may not be comparable to net operating income reported by other equity REITs that define net operating income differently.  We believe that in order to facilitate a clear understanding of our operating results, net operating income should be examined in conjunction with income from continuing operations as presented in our condensed consolidated statements of income.  Net operating income 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 our ability to make distributions.

Same property comparisons

As a result of changes within our total property portfolio, the financial data presented in the Summary of Same Property Comparisons 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 for the quarter periods (herein referred to as “Same Properties”) separate from properties acquired subsequent to the first day in 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 the Same Properties.

Total market capitalization

Total market capitalization is equal to the sum of outstanding shares of Series E Preferred Stock and common stock multiplied by the related closing price of each class at the end of each period presented, the liquidation value of the series D cumulative convertible preferred stock (“Series D Convertible Preferred Stock”), and total debt.

Unencumbered net operating income as a percentage of total net operating income

Unencumbered net operating income as a percentage of total net operating income 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 net operating income as a percentage of total net operating income in order to assess its compliance with its financial covenants under our debt obligations because the measure serves as a proxy for a financial measure under certain of our debt obligations.  Unencumbered net operating income represents net operating income derived from assets which are not subject to any mortgage, deed of trust, lien, or other security interest.

Weighted average interest rate for capitalization

The weighted average interest rate for calculating capitalization of interest required pursuant to GAAP represents a weighted average rate based on the rates applicable to borrowings outstanding during the period and includes the impact of our interest rate hedge agreements, amortization of debt discounts/premiums, amortization of loan fees, and other bank fees.  A separate calculation is performed each month to determine our weighted average interest rate for capitalization for the month.  The rate will vary each month due to changes in variable interest rates, outstanding debt balances, the proportion of variable rate debt to fixed rate debt, the amount and terms of effective interest rate hedge agreements, and the amount of loan fee amortization.

Weighted average shares for calculating FFO, FFO, as adjusted, and AFFO per share

Weighted average shares represent the weighted average of common shares outstanding during the period.  The following calculation of weighted average shares was applied to arrive at FFO per share attributable to Alexandria Real Estate Equities, Inc.’s **** common stockholders, FFO per share attributable to Alexandria Real Estate Equities, Inc.’s **** common stockholders, as adjusted, and AFFO per share attributable to Alexandria Real Estate Equities, Inc.’s **** common stockholders:
