Company Profile

December 31, 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, developing, redeveloping, and acquiring high-quality, sustainable real estate for the broad and diverse life science industry.  Founded in 1994, Alexandria was the first REIT to identify and pursue the laboratory niche and has since had the first-mover advantage in the core life science cluster locations including Greater Boston, San Francisco Bay Area, San Diego, New York City, Seattle, Suburban Washington, D.C., and Research Triangle Park.  Alexandria’s high-credit client tenants span the life science industry, including renowned academic and medical institutions, multinational pharmaceutical companies, public and private biotechnology entities, United States government research agencies, medical device companies, industrial biotech companies, venture capital firms, and life science product and service companies.  As the recognized real estate partner of the life science industry, Alexandria has a superior track record in driving client tenant productivity and innovation through its best-in-class laboratory and office space, collaborative locations adjacent to leading academic and medical institutions, unparalleled life science real estate expertise and services, and longstanding and expansive network in the life science community, which we believe result in higher occupancy levels, longer lease terms, higher rental income, higher returns, and greater long-term asset value. For additional information on Alexandria Real Estate Equities, Inc., please visit www.are.com.

Unique Niche Strategy

Alexandria’s primary business objective is to maximize stakeholder value by providing its stakeholders 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.  Alexandria was founded in 1994 by Jerry M. Sudarsky and Joel S. Marcus.  Alexandria executed its initial public offering in 1997 and received its investment-grade ratings in 2011.

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, and expertise) 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 Alexandria with solid and stable cash flows.  Investment-grade client tenants represented 47% of Alexandria’s total annualized base rent as of December 31, 2012.  Investment-grade client tenants represented 72% of Alexandria’s top 10 client tenants by annualized base rent as of December 31, 2012.  As of December 31, 2012, our multinational pharmaceutical client tenants represented approximately 26.5% of our annualized base rent, led by Bristol-Myers Squibb Company, Eli Lilly and Company, GlaxoSmithKline plc, Novartis AG, Pfizer Inc., and Roche; revenue-producing life science product and service, medical device, and industrial biotech 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 16.7% 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 16.2% and included Amgen Inc., Biogen Idec Inc., Celgene Corporation, Gilead Sciences, Inc., and Onyx Pharmaceuticals, Inc.; private biotechnology companies represented approximately 13.7% and included high-quality, leading-edge companies with blue-chip venture and institutional investors, including Constellation Pharmaceuticals, Inc., Epizyme, Inc., FibroGen, Inc., and FORMA Therapeutics, Inc.; and the remaining approximately 4.3% consisted of traditional office client 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 Alexandria from all other publicly traded real estate investment trusts and real estate companies.

VALUE-ADDED OPPORTUNITIES AND EXTERNAL GROWTH

As of December 31, 2012, 96% of our leases contained annual rent escalations that were either fixed or based on a consumer price index or another index.  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 contractual cash rents related to our value-added projects to increase over time.  Initial stabilized yield is calculated as the quotient of the estimated amounts of net operating income and our investment in the property at stabilization (“Initial Stabilized Yield”).

During the three months and year ended December 31, 2012, we executed leases aggregating 265,000 and 1,135,000 rentable square feet, respectively, related to our development and redevelopment projects.

(1)Represents a one-building project with two towers totaling 386,275 rentable square feet.  ARIAD Pharmaceuticals, Inc. leased 100% of the 216,926 rentable square feet at 125 Binney Street and 27,197 rentable square feet at 75 Binney Street, with additional potential expansion opportunities through June 30, 2014.  See page 10 for additional details on current assumptions included in our guidance for funding the cost to complete the development of 75/125 Binney Street.

(2)We have an additional 40% of the 419,806 rentable square feet that are at the letter of intent stage.

(3)Dana-Farber Cancer Institute, Inc. also has an option to lease an additional two floors of approximately 99,000 rentable square feet, or an additional 24% of the total rentable square feet of our unconsolidated joint venture development project through June 2014.

(4)Represents the total venture cost at completion.  As of December 31, 2012, our equity investment was approximately $28.7 million related to our 27.5% ownership interest in the unconsolidated real estate entity.  Our expected remaining cash commitment to the venture of approximately $16.9 million is less than the $22.3 million received in March 2012 from an in-substance partial sale of our interest in the underlying real estate.

BALANCE SHEET STRATEGY AND SIGNIFICANT MILESTONES

Our balance sheet strategy continues to focus on our leverage target of achieving net debt to adjusted EBITDA of 6.5x by December 31, 2013, by funding our significant development and redevelopment projects in 2013 with leverage-neutral sources of capital and by continuing to execute our asset recycling program.  During 2012, we executed our capital strategy and proved that we have access to diverse sources of capital that we believe is strategically important to our long-term capital structure.  These sources of capital included 1) real estate asset dispositions, 2) secured construction project financing, 3) unsecured line of credit, 4) unsecured note payable, 5) joint venture capital, 6) preferred stock, and 7) common stock through our “at the market” common stock offering program.

Real estate asset sales

We continue the disciplined execution of our asset recycling program to monetize non-strategic operating 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 maintaining specific land parcels for future growth.

A portion of our projected 2013 asset sales is under negotiation and we expect to identify the remainder of the assets for disposition in the first half of 2013 in order to seek to achieve our target dispositions.

The following table presents our completed real estate asset sales:

(1)Annualized using actual year-to-date results as of the quarter end prior to date of sale or December 31, 2012.

(2)Properties sold to residential developers.

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

(4)Properties were sold to client tenants.

(5)In March 2012, we completed an in-substance partial sale of our interest in underlying real estate supporting a project with 414,000 rentable square feet for approximately $31.4 million, or approximately $275 per rentable square foot.

(6)The property is expected to become 74% vacant in 2013 and the current buyer is expected to significantly renovate the property into medical office use.  The sales price of 1124 Columbia Street includes a $29.8 million secured note receivable due in 2015 with an option to extend the maturity date by one year.  As of December 31, 2012, this property is classified in discontinued operations.

(7)These properties met the classification for discontinued operations in January 2013 and were classified as operating properties as of December 31, 2012.  We completed the sale on February 1, 2013, and recognized a $0.1 million gain upon the closing of the transaction.

(8)These properties are expected to become 17% vacant in 2013, with significant additional vacancy in subsequent years, and the buyer is expected to significantly renovate the property at 1201 Clopper Road.

Impairment of real estate assets

During the three months ended September 30, 2012, we committed to sell four operating properties comprised of 1124 Columbia Street in the Seattle market and One Innovation Drive, 377 Plantation Street, and 381 Plantation Street in the suburban Greater Boston market, aggregating 504,130 rentable square feet, rather than to hold them on a long-term basis.  At the time of our commitment to dispose of these assets, these four properties were on average 94% occupied and generated approximately $12.8 million in annual operating income.  Upon our commitment to sell, we wrote down the value of these assets to our estimate of fair value, based on the anticipated sales price, less cost to sell.  As a result, we recognized an impairment charge of approximately $9.8 million.  In December 2012, we entered into an agreement with a third party to sell 1124 Columbia Street, at a price of $42.6 million which was below our reduced carrying value as of September 30, 2012.  As a result we recognized an additional impairment charge of $1.6 million to write down the carrying value to our revised estimated fair value less cost to sell.  In January 2013, we completed the sale of this property and no gain or loss on sale was recognized.

During the three months ended December 31, 2012, we committed to sell a land parcel with 50,000 developable square feet rather than hold it on a long-term basis for future development.  Upon our decision to sell, we wrote down the value of the land parcel to our estimate of fair value, based on the anticipated sales price, less cost to sell.  As a result, we recognized an impairment charge of approximately $2.1 million.

Sale of land parcel

In March 2012, we completed an in-substance partial sale of our interest in a joint venture that owned a land parcel supporting a future building with 414,000 rentable square feet in the Longwood Medical Area of the Greater Boston market to a newly formed joint venture (the “Restated JV”) with National Development and Charles River Realty Investors, and admitted as a 50% member Clarion Partners, LLC, resulting in a reduction of our ownership interest from 55% to 27.5%.  The transfer of one-half of our 55% ownership interest in this real estate venture to Clarion Partners, LLC, was accounted for as an in-substance partial sale of an interest in the underlying real estate.  In connection with the sale of one-half of our 55% ownership interest in the land parcel, we received a special distribution of approximately $22.3 million, which included the recognition of a $1.9 million gain on sale of land and approximately $5.4 million from our share of loan refinancing proceeds.  The land parcel we sold in March 2012 did not meet the criteria for classification as 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 (loss)  from discontinued operations in the income statement.  Accordingly, we classified the $1.9 million gain on sale of land below income (loss) from discontinued operations, net, in the 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.  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 December 31, 2012, the outstanding balance on the construction loan was $61.0 million.  We do not expect our share of capital contributions through the completion of the project to exceed the approximate $22.3 million in net proceeds received in this transaction.  Construction of this $350 million project commenced in April 2012.  The initial occupancy date for this project is expected to be in the fourth quarter of 2014.  The project is 37% pre-leased to Dana-Farber Cancer Institute, Inc.  In addition, Dana-Farber Cancer Institute, Inc. has an option to lease an additional two floors approximating 99,000 rentable square feet, or 24% of the total rentable square feet of the project.  In addition to our economic share of the joint venture, we also expect to earn development and other fees of approximately $3.5 million through 2015, and recurring annual property management fees thereafter, from this project.

“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.  During the year ended December 31, 2012, we sold an aggregate of 1,366,977 shares of common stock for gross proceeds of approximately $100.0 million at an average stock price of $73.15 and net proceeds of approximately $97.9 million, including commissions and other expenses of approximately $2.1 million.  Net proceeds from the sales were used to pay down the outstanding balance on our senior unsecured line of credit or other borrowings, and for general corporate purposes.  As of December 31, 2012, approximately $150.0 million of our common stock remained available for issuance under the “at the market” common stock offering program.

Secured construction loan for development project in San Francisco Bay Area market

In June 2012, we closed a secured construction loan with aggregate commitments of $55.0 million.  We have an option to extend the stated maturity date of July 1, 2015, by one year, twice, to July 1, 2017.  The construction loan bears 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 December 31, 2012, commitments of $38.1 million were available under this loan.

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 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 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 for the three months ended June 30, 2012.

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, or approximately $129.6 million in aggregate, and paid $0.5234375 per share, representing accumulated and unpaid dividends to the redemption date on such shares.  We announced the redemption and recognized a preferred stock redemption charge of approximately $6.0 million to net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders in March 2012, related to the write-off of original issuance costs of the Series C Preferred Stock.

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 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.

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 for the three months ended March 31, 2012.

Retirement of 3.70% unsecured senior convertible notes

In January 2012, we repurchased approximately $83.8 million in principal amount of our 3.70% unsecured senior convertible notes (“3.70% Unsecured Senior Convertible Notes”) at par, pursuant to options exercised by holders thereof under the indenture governing the notes.  In April 2012, we repurchased the remaining outstanding $1.0 million in principal amount of the notes.  In aggregate, we repurchased approximately $84.8 million in principal amount of the notes and we did not recognize a gain or loss as a result during the year ended December 31, 2012.

GUIDANCE

Earnings outlook

Based on our current view of existing market conditions and certain current assumptions, we expect that our 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, will be 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 February 7, 2013	Reported on December 5, 2012
Earnings per share attributable to Alexandria Real Estate Equities, Inc.’s common stockholders – diluted	$1.41 to $1.61	$1.39 to $1.59

FFO per share attributable to Alexandria Real Estate Equities, Inc.’s common stockholders – diluted	$4.44 to $4.64	$4.40 to $4.60
Key projection assumptions:
Same property net operating income growth – cash basis	4% to 7%	4% to 7%

Amortization of above and below market leases	$3 to $4 million	$3 to $4 million
G&A 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

As of December 31, 2012, we had approximately $431.6 million and $199.7 million of construction in progress related to our three North American development and eight 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, net operating income, 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 page 9 and 10.  Certain key assumptions regarding our projections, including the impact of various development and redevelopment projects, are included in the tables above and on the following page.

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 net operating income growth are included in the tables on this page 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, 2011, and the “Risk Factors” section of Item 1A of our quarterly report on Form 10-Q for the period ended September 30, 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 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.

(1)	See “Projection Results – Key Projection Assumptions” on the previous page.
(2)	A portion of our projected 2013 asset sales is under negotiation and we expect to identify the remainder of the assets for disposition in the first half of 2013 in order to achieve our targeted dispositions.
(3)	Our guidance has assumed transfer of 50% of our ownership interest in the 75/125 Binney Street project to be accounted for as an in-substance partial sale of an interest in a land parcel, with the resulting entity presented as an unconsolidated joint venture (the “Binney JV”) in our financial statements. This sale of a land parcel is included in our total projected asset sales for 2013.
(4)	See “Investment to Complete” columns in the “Development and Redevelopment Projects in North America” table on the following page for additional details underlying this estimate. Our guidance for 2013 development, redevelopment, and construction spending of $545 to $595 million includes our estimated share of incremental capital required to complete the 75/125 Binney Street Project. See page 10 for additional details on the 75/125 Binney Street Project.
(5)	Our guidance has assumed no acquisitions, but we review opportunistic acquisitions that we expect to fund on a leverage-neutral basis.
(6)	The reduction in projected secured notes payable of $15 million is related to two loans that were repaid in 2012 prior to their contractual maturity dates in 2013.

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, 2011, and the “Risk Factors” section of Item 1A of our quarterly report on Form 10-Q for the period ended September 30, 2012.  We expect to update our forecast of sources and uses of capital on a quarterly basis.

	Cost to Complete (7)
	2013		Thereafter		Total
ARE investment	$	40,000 - 50,000	$	–	$	40,000 - 50,000

	$	90,000 - 115,000	$	160,000 - 165,000	$	250,000 - 280,000

(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. For example, the redevelopment project at 1616 Eastlake Avenue represents the conversion of two floors from office to laboratory/office aggregating 66,776 rentable square feet. The remaining rentable square feet of 101,714 at this property not undergoing active redevelopment was 74.8% occupied at December 31, 2012, and is included in our operating statistics.
(2)	Represents rentable square feet subject to letters of intent.
(3)	As of December 31, 2012, 96% of our leases contained annual rent escalations that were either fixed or based on a consumer price index or another index. 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 contractual cash rents related to our value-added projects to increase over time. 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.
(4)	We expect to deliver 54,102 rentable square feet, or 79% of the total project, to Genomatica, Inc. in the fourth quarter of 2013. Genomatica, Inc. is contractually required to lease the remaining 14,411 rentable square feet no later than 18 to 24 months following the delivery of the initial 54,102 rentable square foot space.
(5)	As of December 31, 2012, this project was classified in land undergoing preconstruction activities (additional CIP) in North America. This project will be transferred into active development upon commencement of vertical construction during the three months ended March 31, 2013.
(6)	ARIAD Pharmaceuticals, Inc. has potential additional expansion opportunities through June 2014.
(7)	Our guidance has assumed transfer of 50% of our ownership interest in the 75/125 Binney Street project to be accounted for as an in-substance partial sale of an interest in a land parcel, with the resulting entity presented as an unconsolidated joint venture (the “Binney JV”) in our financial statements. This sale of a land parcel is included in our total projected asset sales for 2013. The total remaining cost to complete for the 75/125 Binney Street project is expected to aggregate approximately $264 million through 2016, of which $101 million is expected to be invested in 2013. The projected sources of funding for the $264 million cost to complete for this project include a secured construction loan of approximately $190 million to $205 million, Binney JV partner capital contribution of approximately $75 million to $80 million, (approximately $20 million to $25 million to be used towards construction) and our investment in the project of approximately $40 million to $50 million. Our guidance for 2013 development, redevelopment, and construction spending of $545 to $595 million, shown on page 8, includes our estimated investment in the project of approximately $40 million to $50 million into the Binney JV.

About the Company

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

Non-GAAP Measures

Funds from operations and funds from operations, 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 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 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 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 (losses) from sales of real estate and land parcels and impairments of 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 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-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 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 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.

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, impairment of land parcel, 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.  Real estate impairments have been excluded in deriving net operating income 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 net operating income 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 net operating income 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.  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.  The following table presents a reconciliation of net operating income from continuing operations to income from continuing operations, and a reconciliation of net operating income from discontinued operations to income from discontinued operations, net:

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

As of December 31, 2012, our active development and redevelopment projects represent 12% of gross investments in real estate, a significant amount of which is pre-leased and expected to be delivered over the next one to eight quarters.  Land undergoing preconstruction activities represents 7% of gross investment in real estate.  The largest project included in land undergoing preconstruction consists of our 1.6 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.  Our goal is to reduce non-income-producing assets as a percentage of our gross investments in real estate to 15-17% by December 31, 2013, and 15% or less for the subsequent periods.

The following table presents the current assumptions included in our guidance for funding of the cost to complete the 75/125 Binney Street project:

	Cost to Complete (7)

ARE investment	$	40,000 - 50,000	$	–	$	40,000 - 50,000

(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. For example, the redevelopment project at 1616 Eastlake Avenue represents the conversion of two floors from office to laboratory/office aggregating 66,776 rentable square feet. The remaining rentable square feet of 101,714 at this property not undergoing active redevelopment was 74.8% occupied at December 31, 2012, and is included in our operating statistics.
(2)	Represents rentable square feet subject to letters of intent.
(3)	As of December 31, 2012, 96% of our leases contained annual rent escalations that were either fixed or based on a consumer price index or another index. 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 contractual cash rents related to our value-added projects to increase over time. 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.
(4)	We expect to deliver 54,102 rentable square feet, or 79% of the total project, to Genomatica, Inc. in the fourth quarter of 2013. Genomatica, Inc. is contractually required to lease the remaining 14,411 rentable square feet no later than 18 to 24 months following the delivery of the initial 54,102 rentable square foot space.
(5)	As of December 31, 2012, this project was classified in land undergoing preconstruction activities (additional CIP) in North America. This project will be transferred into active development upon commencement of vertical construction during the three months ended March 31, 2013.
(6)	ARIAD Pharmaceuticals, Inc. has potential additional expansion opportunities through June 2014.
(7)	Our guidance has assumed transfer of 50% of our ownership interest in the 75/125 Binney Street project to be accounted for as an in-substance partial sale of an interest in a land parcel, with the resulting entity presented as an unconsolidated joint venture (the “Binney JV”) in our financial statements. This sale of a land parcel is included in our total projected asset sales for 2013. The total remaining cost to complete for the 75/125 Binney Street project is expected to aggregate approximately $264 million through 2016, of which $101 million is expected to be invested in 2013. The projected sources of funding for the $264 million cost to complete for this project include a secured construction loan of approximately $190 million to $205 million, Binney JV partner capital contribution of approximately $75 million to $80 million, (approximately $20 million to $25 million to be used towards construction) and our investment in the project of approximately $40 million to $50 million. Our guidance for 2013 development, redevelopment, and construction spending of $545 to $595 million, shown on page 8, includes our estimated investment in the project of approximately $40 million to $50 million into the Binney JV.

Investment in Unconsolidated Real Estate Entity and Future Value-Added Projects in North America

Investment in unconsolidated real estate entity

In March 2012, we completed an in-substance partial sale of our interest in a joint venture that owned a land parcel supporting a future building with414,000 rentable square feet in the Longwood Medical Area of the Greater Boston market to a newly formed joint venture (the “Restated JV”) with National Development and Charles River Realty Investors, and admitted as a 50% member Clarion Partners, LLC, resulting in a reduction of our ownership interest from 55% to 27.5%.  The transfer of one-half of our 55% ownership interest in this real estate venture to Clarion Partners, LLC, was accounted for as an in-substance partial sale of an interest in the underlying real estate.  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 December 31, 2012, the outstanding balance on the construction loan was $61.0 million.  We do not expect our share of capital contributions through the completion of the project to exceed the approximate $22.3 million in net proceeds received in this transaction.  Construction of this $350 million project commenced in April 2012.  The initial occupancy date for this project is expected in the fourth quarter of 2014, the project is 37% pre-leased to Dana-Farber Cancer Institute, Inc.  In addition, Dana-Farber Cancer Institute, Inc. has an option to lease an additional two floors approximating 99,000 rentable square feet, or 24% of the total rentable square feet of the project.  We expect to earn development and other fees of approximately $3.5 million through 2015, and recurring annual property management fees thereafter, from this project.  As of December 31, 2012, key information regarding the unconsolidated real estate entity in the Greater Boston market was as follows:

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.
(2)	Total joint venture loan commitment is comprised of borrowings up to $175.2 million which bear interest at fixed interest rate of 5.25%, and additional borrowings up to $38 million that bear interest at LIBOR plus 3.75% with a floor of 5.25%, which will be used to fund tenant improvements, leasing commissions, and other related expenses. 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.
(3)	Our expected remaining cash commitment to the venture of approximately $16.9 million is less than the $22.3 million received in March 2012 from the sale of one-half of our 55% interest in a land parcel.

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”) 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, 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 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 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 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 not related to core operations, not dependent upon historical costs, and not subject to judgmental valuation 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:

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-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 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 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.

Annualized base rent

Annualized base rent means the annualized fixed base rental amount in effect as of the end of the period, 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 client 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 except when there is significant market demand for high-quality 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.

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 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 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 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 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 (losses) from sales of real estate and land parcels and impairments of 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 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 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 included in land undergoing preconstruction consists of our 1.6 million developable square feet at Alexandria Center™ at Kendall Square in East Cambridge, Massachusetts.

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.

Initial stabilized yield - cash

Initial Stabilized Yield is calculated as the quotient of net operating income and our investment in the property at stabilization.  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 contractual cash rents related to our value-added projects to increase over time.  Our Initial Stabilized Yield excludes the impact of leverage.

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
	12/31/12		9/30/12		6/30/12		3/31/12		12/31/11

Interest coverage ratio – trailing 12 months	3.2x		3.2x		3.3x		3.4x		3.4x

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, impairment of land parcel, 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.  Real estate impairments have been excluded in deriving net operating income 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 net operating income 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 net operating income 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.  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 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 our compliance with our 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 is derived from assets classified in continuing operations which are not subject to any mortgage, deed of trust, lien, or other security interest as of the period for which income is presented.  Unencumbered net operating income for periods through September 30, 2012, has been reclassified to conform to current period presentation related to discontinued operations.

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.
