BALANCE SHEET

Investment grade ratings and credit metrics

In July 2011, we received investment grade ratings from two major rating agencies.  Receipt of our investment grade ratings was a significant milestone for the Company that we believe will provide long-term value to our stockholders.  Key strengths of our balance sheet and business which highlight our investment grade credit profile include, among others, balance sheet liquidity, diverse and credit worthy tenant base, well located properties proximate to leading research institutions, favorable lease terms, stable occupancy and cash flows, and demonstrated life science and real estate expertise.  This significant milestone broadens our access to another key source of debt capital and allows us to continue to pursue our long-term capital, investment, and operating strategies.  Issuance of investment grade unsecured notes will allow us to transition from bank debt financing to unsecured notes, from variable rate debt to fixed rate debt, and from short-term debt to long-term debt.

Unhedged variable rate debt

We expect to transition from short-term and medium-term bank debt to long-term fixed rate debt over the next several years. While this transition of bank debt is in process, we will utilize interest rate swap and/or cap agreements to reduce our interest rate risk.  In December 2011, we executed interest rate swap agreements and reduced our unhedged variable rate debt exposure from 51% as of September 30, 2011, to 21% as of December 31, 2011.  We expect to keep our unhedged variable rate debt at approximately 20% or less of our total debt.

2017 unsecured bank term loan

In December 2011, we closed a $600 million unsecured bank term loan (the “2017 Unsecured Bank Term Loan”), which matures in January 2017, assuming we exercise our sole right to extend the maturity date by one year.  The applicable margin for LIBOR borrowings under the 2017 Unsecured Bank Term Loan as of December 31, 2011, was 1.50%.  Our 2017 Unsecured Bank Term Loan may be repaid at any date prior to maturity without a prepayment penalty.  Net proceeds from the 2017 Unsecured Bank Term Loan were used to reduce outstanding borrowings on our unsecured line of credit.

Refinancing of secured loan

In December 2011, we extended the maturity date of a $76 million secured loan to April 2014.  As of December 31, 2011, the interest rate for this secured loan was 2.29%.

2016 unsecured bank term loan

In February 2011, we entered into a $250 million unsecured bank term loan.  In June 2011, we amended this $250 million unsecured bank term loan (as amended, the “2016 Unsecured Bank Term Loan”) to, among other things, increase the borrowings from $250 million to $750 million and to extend the maturity from January 2015 to June 2016, assuming we exercise our sole right to extend the maturity date by one year.  The applicable margin for the LIBOR borrowings under the 2016 Unsecured Bank Term Loan as of December 31, 2011, was 1.65%.  The 2016 Unsecured Bank Term Loan may be repaid at any date prior to maturity without a prepayment penalty.  The net proceeds from this 2016 Unsecured Bank Term Loan were used to reduce outstanding borrowings on the 2012 Unsecured Bank Term Loan (defined below) from $750 million to $250 million.  As a result of this early repayment, in the three months ended June 30, 2011, we recognized a loss on early extinguishment of debt of approximately $1.2 million related to the write-off of unamortized loan fees.

Debt financings (continued)

Unsecured line of credit

In January 2011, we entered into a third amendment (the “Third Amendment”) to our second amended and restated credit agreement dated October 31, 2006, as further amended on December 1, 2006, and May 2, 2007 (the “Prior Credit Agreement,” and as amended by the Third Amendment, the “Amended Credit Agreement”), with Bank of America, N.A., as administrative agent, and certain lenders. The Third Amendment amended the Prior Credit Agreement to, among other things, increase the maximum permitted borrowings under the unsecured line of credit from $1.15 billion to $1.5 billion, plus a $750 million unsecured bank term loan (the “2012 Unsecured Bank Term Loan” and together with the unsecured line of credit, the “Unsecured Credit Facility”) and provided an accordion option to increase commitments under the Unsecured Credit Facility by up to an additional $300 million.  The applicable margin for LIBOR borrowings outstanding under our unsecured line of credit as of December 31, 2011, was 2.30%.  The applicable margin for the LIBOR borrowings under the 2012 Unsecured Bank Term Loan was not amended in the Third Amendment and was 0.70% as of December 31, 2011.

Under the Third Amendment, the maturity date for the unsecured line of credit is January 2015, assuming we exercise our sole right under the amendment to extend this maturity date twice by an additional six months after each exercise.  The maturity date of the 2012 Unsecured Bank Term Loan is October 2012.  The Third Amendment modified certain financial covenants with respect to the Unsecured Credit Facility, including the fixed charge coverage ratio, secured debt ratio, leverage ratio, and minimum book value, and added covenants relating to an unsecured leverage ratio and unsecured debt yield.

Debt repayments

During the year ended December 31, 2011, we reduced the outstanding balances of our 3.70% Unsecured Convertible Notes, 2012 Unsecured Bank Term Loan, and various secured loans.

$ 34,060 $ $ 772,810 $ 6,485

(1)            See 2016 Unsecured Bank Term Loan discussion above.

At the beginning of 2011, our strategy was to reduce a portion of our outstanding balance of the 3.70% Unsecured Convertible Notes. We were also focused on the refinancing of certain near term bank debt maturities, prior to engaging in the rating assessment process with certain rating agencies.  During the year ended December 31, 2011, we repurchased, in privately negotiated transactions, approximately $217.1 million of certain of our 3.70% Unsecured Convertible Notes for an aggregate cash price of approximately $221.4 million.  As a result of these repurchases, we recognized an aggregate loss on early extinguishment of debt of approximately $5.2 million for the year ended December 31, 2011.  We did not repurchase any of our 3.70% Unsecured Convertible Notes during the three months ended December 31, 2011.  During January 2012, we repurchased approximately $83.8 million in principal amount of our 3.70% Unsecured Convertible Notes at par, pursuant to options exercised by holders thereof under the indenture governing the notes.  We do not expect to recognize any gain or loss as a result of this repurchase.  As of February 7, 2012, approximately $1.0 million of our 3.70% Unsecured Convertible Notes remained outstanding.

Asset sales

During the year ended December 31, 2011, we sold two properties.  The net proceeds from these sales were used to reduce outstanding borrowings under our unsecured line of credit.


Date of Sale Sale Price Sale Price Per<br> Rentable Square Foot Gain on Sale
Land parcel in San Diego, California August 2011 $ 17,300 $ 70 $ 46
13-15 DeAngelo Drive, Suburbs of Boston, Massachusetts October 2011 2,900 97
$ 20,200 $ 72 $ 46

In August 2011, we sold a parcel of land located in San Diego, California, for approximately $17.3 million at a gain of $46,000.  The buyer is expected to construct a building with approximately 249,000 rentable square feet, representing a sale price of approximately $70 per rentable square foot.

During the three months ended September 30, 2011, 13-15 DeAngelo Drive, a vacant 30,000 rentable square foot property, located in the suburbs of Boston, Massachusetts, met the criteria for classification as “held for sale.”  This property had been occupied by a life science tenant through June 30, 2011.  Upon move out, a user of the building presented an offer for the purchase of the building in the three months ended September 30, 2011.  As a result, we recognized an impairment charge of approximately $1.0 million in the three months ended September 30, 2011, to adjust the carrying value to the estimated fair value less costs to sell.  In October 2011, we sold 13-15 DeAngelo Drive to that user for approximately $2.9 million, representing a sale price of approximately $97 per rentable square foot.

Follow-on common stock offering

In May 2011, we completed a follow-on common stock offering to fund the purchase of 409 and 499 Illinois Street and to fund construction activities among other uses. We acquired 409 and 499 Illinois Street, a newly and partially completed world-class 453,256 rentable square foot laboratory/office development project located on a highly desirable waterfront location in Mission Bay, San Francisco, for approximately $293 million.  409 Illinois Street is a 241,659 rentable square foot tower that is 97% leased to a life science company through November 2023.  499 Illinois Street is a vacant 211,597 rentable square foot tower in shell condition for which we plan to complete the development.

CORE OPERATING METRICS

Total revenues, net operating income, and operating margin

Total revenues for the three months ended December 31, 2011, were $145.8 million, as compared to total revenues for the three months ended December 31, 2010, of $131.8 million.  Total revenues for the year ended December 31, 2011, were $573.4 million as compared to the total revenues for the year ended December 31, 2010, of $485.7 million.  Net operating income for the three months ended December 31, 2011, was $101.8 million, compared to net operating income for the three months ended December 31, 2010, of $95.1 million.  Net operating income for the year ended December 31, 2011, was $404.8 million, compared to net operating income for the year ended December 31, 2010 of $353.6 million.  Our operating margin for the three months ended December 31, 2011, was 70%, compared to operating margin for the three months ended December 31, 2010, of 72%.  Our operating margin for the year ended December 31, 2011, was 71%, compared to operating margin for the year ended December 31, 2010, of 73%.

Net operating income is projected to increase significantly quarter to quarter from the three months ended December 31, 2011, to the three months ended December 31, 2012, primarily related to the completion and delivery of current and future redevelopment and development projects, a significant amount of which is pre-leased.  Additionally, the increase in net operating income is also due to recent and anticipated leasing activity, and lease-up of vacant space.  See additional information related to projected net operating income for the three months ended December 31, 2012, in the guidance section of this report.  As we complete and deliver projects currently under construction, certain project costs, including interest, property taxes, and other project costs, will no longer qualify for capitalization and will be expensed as incurred.

As of December 31, 2011 and 2010, we owned 173 and 167 properties, respectively. As a result of changes within our total property portfolio, our financial results included 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 separate from properties acquired subsequent to the first period presented, properties undergoing active redevelopment and active development, and corporate entities (legal entities performing general and administrative functions), which are excluded from same property results.  Additionally, rental revenues from lease termination fees, if any, are excluded from the results of the same properties.

Client tenant base

The quality, diversity, breadth, and depth of our significant relationships with our life science client tenants provide Alexandria Real Estate Equities, Inc. with solid cash flows. As of December 31, 2011, Alexandria’s multinational pharmaceutical client tenants represented approximately 26% of our annualized base rent, led by Novartis AG, Eli Lilly and Company, Roche Holding Ltd, Bristol-Myers Squibb Company, GlaxoSmithKline plc, and Pfizer Inc.; public biotechnology companies represented approximately 18% and included Amgen Inc., Gilead Sciences, Inc., Biogen Idec Inc., and Celgene Corporation; revenue-producing life science product and service companies represented approximately 22%, led by Illumina, Inc., Quest Diagnostics Incorporated, Qiagen N.V., Laboratory Corporation of America Holdings, and Monsanto Company; government agencies and renowned medical and research institutions represented approximately 16% and included Massachusetts Institute of Technology, The Scripps Research Institute, The Regents of the University of California, Fred Hutchinson Cancer Research Center, University of Washington, Sanford-Burnham Medical Research Institute, and the United States Government; private biotechnology companies represented approximately 15% and included high-quality, leading-edge companies with blue-chip venture and institutional investors, including FibroGen, Inc., Achaogen Inc., and Forma Therapeutics, Inc.; and the remaining approximately 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 set the Company apart from all other publicly traded REITs and real estate companies.

VALUE ADDED OPPORTUNITIES AND EXTERNAL GROWTH

Development and redevelopment

During the year ended December 31, 2011, we executed leases aggregating 542,120 and 451,535 rentable square feet related to our development and redevelopment projects, respectively.  The leases aggregating 542,120 rentable square feet related to our development projects include the recent lease up of 45,255 rentable square feet at 4755 Nexus Center Drive, a recently acquired property currently undergoing redevelopment.

During the year ended December 31, 2011, we delivered approximately 58,804 rentable square feet at 455 Mission Bay Boulevard, a 210,000 rentable square foot multi-tenant ground-up development project located in the San Francisco — Mission Bay market.  This property is currently 92.4% leased.  Our stabilized yields on a cash and GAAP basis for this property were approximately 8.5% and 8.4%, 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 August 2011, we completed the ground-up development of 7 Triangle Drive, a 96,626 rentable square foot single-tenant building located in the Research Triangle Park market, which is currently 100% leased as of December 31, 2011.  The Stabilized Yield on a cash and GAAP basis for this property was approximately 8.5% and 9.8%, respectively.

In October 2011, we commenced the ground up development of a 303,143 rentable square feet single tenant building for Biogen Idec, Inc. at Alexandria CenterTM at Kendall Square.  We expect to achieve a Stabilized Yield on a cash and GAAP basis for this property of 7.5% and 8.1%, respectively.

Non-GAAP measures

Funds from operations

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 NAREIT established the measurement tool of Funds from Operations (“FFO”).  Since its introduction, FFO has become a widely used non-GAAP financial measure among real estate investment trusts (“REITs”).  We believe that FFO is helpful to investors as an additional measure of the performance of an equity REIT.  We compute FFO in accordance with standards established by the Board of Governors of NAREIT in its April 2002 White Paper (the “White Paper”) and related implementation guidance, which may differ from the methodology for calculating FFO utilized by other equity REITs, and, accordingly, may not be comparable to such other REITs.  The White Paper defines FFO as net income (computed in accordance with GAAP), excluding gains from sales, plus real estate related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures.  The primary reconciling item between GAAP net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders and FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders is depreciation and amortization expense. Impairment write-downs of depreciable real estate are excluded from the calculation of FFO and no adjustment to net income (computed in accordance with GAAP) is made. A reconciliation of net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders in accordance with United States generally accepted accounting principles (“GAAP”) to FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders is included in the financial information accompanying this press release.  FFO should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of financial performance, or to cash flows from operating activities (determined in accordance with GAAP) as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to make distributions.

Adjusted funds from operations

Adjusted funds from operations (“AFFO”) is a non-GAAP financial measure we believe is a useful supplemental measure of our performance.  We compute AFFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders by adding to or deducting from FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders (1) recurring and non-recurring capital expenditures required to maintain and re-tenant our properties, (2) second generation tenant improvements and leasing costs on re-tenanted and renewal space (excludes redevelopment expenditures), (3) capitalized income from development projects, (4) gains or losses on early extinguishment of debt, (5) amortization of loan fees, debt premiums/discounts and acquired above and below market leases, (6) effects of deferred rent/straight-line rent and deferred rent/straight-line rent on ground leases, (7) non-cash compensation expense related to restricted stock awards, and (8) other non-cash income or charges, including impairment charges.  AFFO is not intended to represent cash flow for the period, and is only intended to provide an additional measure of performance by adjusting the effect of certain items noted above included in FFO, as well as recurring capital expenditures and leasing costs.  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 attributable to Alexandria Real Estate Equities, Inc.’s common stockholders.  We also believe that AFFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders provides useful performance information to the investment community about our financial position as compared to other REITs since AFFO is a widely reported measure used by other REITs.  However, other REITs may use different methodologies for calculating AFFO and, accordingly, our AFFO may not be comparable to other REITs.

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 from 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 only 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 our results of operations from 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 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.

ALEXANDRIA REAL ESTATE EQUITIES, INC.

Company Profile

December 31, 2011

The Company

Alexandria Real Estate Equities, Inc. (the “Company” or “Alexandria”), a self-administered and self-managed real estate investment trust (“REIT”), is the largest owner and preeminent REIT, and leading life science real estate company, focused principally on science-driven cluster formation.  Our operating platform is based on the principle of “clustering” with high-quality assets and operations located adjacent to life science research and innovation entities driving growth and technological advances.  The Company has significant real estate assets adjacent to these key life science entities which we believe results in higher occupancy levels, longer lease terms, higher rental income, and higher returns.  Our targeted locations are in the best submarkets within each of the top life science cluster destinations, including San Francisco and San Diego, California; Greater Boston; New York City, New Jersey, and Suburban Philadelphia; Research Triangle Park, North Carolina; Suburban Washington, D.C.; Seattle, Washington; and international locations.  Client tenants include institutional (universities and independent non-profit institutions), pharmaceutical, biotechnology, medical device, product, and service entities, and government agencies.  The Company was founded in 1994 by Jerry M. Sudarsky and Joel S. Marcus and 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 both real estate and life science experience 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 and networks provide Alexandria significant competitive advantages in attracting new business opportunities.

Strategy

Alexandria’s primary business objective is to maximize stockholder value by providing its stockholders with the greatest possible total return 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.

BALANCE SHEET

Investment grade ratings and credit metrics

In July 2011, we received investment grade ratings from two major rating agencies.  Receipt of our investment grade ratings was a significant milestone for the Company that we believe will provide long-term value to our stockholders.  Key strengths of our balance sheet and business which highlight our investment grade credit profile include, among others, balance sheet liquidity, diverse and credit worthy tenant base, well located properties proximate to leading research institutions, favorable lease terms, stable occupancy and cash flows, and demonstrated life science and real estate expertise.  This significant milestone broadens our access to another key source of debt capital and allows us to continue to pursue our long-term capital, investment, and operating strategies.  Issuance of investment grade unsecured notes will allow us to transition from bank debt financing to unsecured notes, from variable rate debt to fixed rate debt, and from short-term debt to long-term debt.

Unhedged variable rate debt

We expect to transition from short-term and medium-term bank debt to long-term fixed rate debt over the next several years. While this transition of bank debt is in process, we will utilize interest rate swap and/or cap agreements to reduce our interest rate risk.  In December 2011, we executed interest rate swap agreements and reduced our unhedged variable rate debt exposure from 51% as of September 30, 2011, to 21% as of December 31, 2011.  We expect to keep our unhedged variable rate debt at approximately 20% or less of our total debt.

Debt financings (continued)

2017 unsecured bank term loan

In December 2011, we closed a $600 million unsecured bank term loan (the “2017 Unsecured Bank Term Loan”), which matures in January 2017, assuming we exercise our sole right to extend the maturity date by one year.  The applicable margin for LIBOR borrowings under the 2017 Unsecured Bank Term Loan as of December 31, 2011, was 1.50%.  Our 2017 Unsecured Bank Term Loan may be repaid at any date prior to maturity without a prepayment penalty.  Net proceeds from the 2017 Unsecured Bank Term Loan were used to reduce outstanding borrowings on our unsecured line of credit.

Refinancing of secured loan

In December 2011, we extended the maturity date of a $76 million secured loan to April 2014.  As of December 31, 2011, the interest rate for this secured loan was 2.29%.

2016 unsecured bank term loan

In February 2011, we entered into a $250 million unsecured bank term loan.  In June 2011, we amended this $250 million unsecured bank term loan (as amended, the “2016 Unsecured Bank Term Loan”) to, among other things, increase the borrowings from $250 million to $750 million and to extend the maturity from January 2015 to June 2016, assuming we exercise our sole right to extend the maturity date by one year.  The applicable margin for the LIBOR borrowings under the 2016 Unsecured Bank Term Loan as of December 31, 2011, was 1.65%.  The 2016 Unsecured Bank Term Loan may be repaid at any date prior to maturity without a prepayment penalty.  The net proceeds from this 2016 Unsecured Bank Term Loan were used to reduce outstanding borrowings on the 2012 Unsecured Bank Term Loan (defined below) from $750 million to $250 million.  As a result of this early repayment, in the three months ended June 30, 2011, we recognized a loss on early extinguishment of debt of approximately $1.2 million related to the write-off of unamortized loan fees.

Unsecured line of credit

In January 2011, we entered into a third amendment (the “Third Amendment”) to our second amended and restated credit agreement dated October 31, 2006, as further amended on December 1, 2006, and May 2, 2007 (the “Prior Credit Agreement,” and as amended by the Third Amendment, the “Amended Credit Agreement”), with Bank of America, N.A., as administrative agent, and certain lenders. The Third Amendment amended the Prior Credit Agreement to, among other things, increase the maximum permitted borrowings under the unsecured line of credit from $1.15 billion to $1.5 billion, plus a $750 million unsecured bank term loan (the “2012 Unsecured Bank Term Loan” and together with the unsecured line of credit, the “Unsecured Credit Facility”) and provided an accordion option to increase commitments under the Unsecured Credit Facility by up to an additional $300 million.  The applicable margin for LIBOR borrowings outstanding under our unsecured line of credit as of December 31, 2011, was 2.30%.  The applicable margin for the LIBOR borrowings under the 2012 Unsecured Bank Term Loan was not amended in the Third Amendment and was 0.70% as of December 31, 2011.

Under the Third Amendment, the maturity date for the unsecured line of credit is January 2015, assuming we exercise our sole right under the amendment to extend this maturity date twice by an additional six months after each exercise.  The maturity date of the 2012 Unsecured Bank Term Loan is October 2012.  The Third Amendment modified certain financial covenants with respect to the Unsecured Credit Facility, including the fixed charge coverage ratio, secured debt ratio, leverage ratio, and minimum book value, and added covenants relating to an unsecured leverage ratio and unsecured debt yield.

Debt repayments

During the year ended December 31, 2011, we reduced the outstanding balances of our 3.70% Unsecured Convertible Notes, 2012 Unsecured Bank Term Loan, and various secured loans.

$ 34,060 $ $ 772,810 $ 6,485

(1)             See 2016 Unsecured Bank Term Loan discussion above.

At the beginning of 2011, our strategy was to reduce a portion of our outstanding balance of the 3.70% Unsecured Convertible Notes. We were also focused on the refinancing of certain near term bank debt maturities, prior to engaging in the rating assessment process with certain rating agencies.  During the year ended December 31, 2011, we repurchased, in privately negotiated transactions, approximately $217.1 million of certain of our 3.70% Unsecured Convertible Notes for an aggregate cash price of approximately $221.4 million.  As a result of these repurchases, we recognized an aggregate loss on early extinguishment of debt of approximately $5.2 million for the year ended December 31, 2011.  We did not repurchase any of our 3.70% Unsecured Convertible Notes during the three months ended December 31, 2011.  During January 2012, we repurchased approximately $83.8 million in principal amount of our 3.70% Unsecured Convertible Notes at par, pursuant to options exercised by holders thereof under the indenture governing the notes.  We do not expect to recognize any gain or loss as a result of this repurchase.  As of February 7, 2012, approximately $1.0 million of our 3.70% Unsecured Convertible Notes remained outstanding.

Asset sales

During the year ended December 31, 2011, we sold two properties.  The net proceeds from these sales were used to reduce outstanding borrowings under our unsecured line of credit.

Asset sales (continued)

In August 2011, we sold a parcel of land located in San Diego, California, for approximately $17.3 million at a gain of $46,000.  The buyer is expected to construct a building with approximately 249,000 rentable square feet, representing a sale price of approximately $70 per rentable square foot.

During the three months ended September 30, 2011, 13-15 DeAngelo Drive, a vacant 30,000 rentable square foot property, located in the suburbs of Boston, Massachusetts, met the criteria for classification as “held for sale.”  This property had been occupied by a life science tenant through June 30, 2011.  Upon move out, a user of the building presented an offer for the purchase of the building in the three months ended September 30, 2011.  As a result, we recognized an impairment charge of approximately $1.0 million in the three months ended September 30, 2011, to adjust the carrying value to the estimated fair value less costs to sell.  In October 2011, we sold 13-15 DeAngelo Drive to that user for approximately $2.9 million, representing a sale price of approximately $97 per rentable square foot.

Follow-on common stock offering

In May 2011, we completed a follow-on common stock offering to fund the purchase of 409 and 499 Illinois Street and to fund construction activities among other uses. We acquired 409 and 499 Illinois Street, a newly and partially completed world-class 453,256 rentable square foot laboratory/office development project located on a highly desirable waterfront location in Mission Bay, San Francisco, for approximately $293 million.  409 Illinois Street is a 241,659 rentable square foot tower that is 97% leased to a life science company through November 2023.  499 Illinois Street is a vacant 211,597 rentable square foot tower in shell condition for which we plan to complete the development.

CORE OPERATING METRICS

Total revenues, net operating income, and operating margin

Total revenues for the three months ended December 31, 2011, were $145.8 million, as compared to total revenues for the three months ended December 31, 2010, of $131.8 million.  Total revenues for the year ended December 31, 2011, were $573.4 million as compared to the total revenues for the year ended December 31, 2010, of $485.7 million.  Net operating income for the three months ended December 31, 2011, was $101.8 million, compared to net operating income for the three months ended December 31, 2010, of $95.1 million.  Net operating income for the year ended December 31, 2011, was $404.8 million, compared to net operating income for the year ended December 31, 2010 of $353.6 million.  Our operating margin for the three months ended December 31, 2011, was 70%, compared to operating margin for the three months ended December 31, 2010, of 72%.  Our operating margin for the year ended December 31, 2011, was 71%, compared to operating margin for the year ended December 31, 2010, of 73%.

Net operating income is projected to increase significantly quarter to quarter from the three months ended December 31, 2011, to the three months ended December 31, 2012, primarily related to the completion and delivery of current and future redevelopment and development projects, a significant amount of which is pre-leased.  Additionally, the increase in net operating income is also due to recent and anticipated leasing activity, and lease-up of vacant space.  See additional information related to projected net operating income for the three months ended December 31, 2012, in the guidance section of this report.  As we complete and deliver projects currently under construction, certain project costs, including interest, property taxes, and other project costs, will no longer qualify for capitalization and will be expensed as incurred.

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 set the Company apart from all other publicly traded REITs and real estate companies.

VALUE ADDED OPPORTUNITIES AND EXTERNAL GROWTH

Development and redevelopment

During the year ended December 31, 2011, we executed leases aggregating 542,120 and 451,535 rentable square feet related to our development and redevelopment projects, respectively.  The leases aggregating 542,120 rentable square feet related to our development projects include the recent lease up of 45,255 rentable square feet at 4755 Nexus Center Drive, a recently acquired property currently undergoing redevelopment.

During the year ended December 31, 2011, we delivered approximately 58,804 rentable square feet at 455 Mission Bay Boulevard, a 210,000 rentable square foot multi-tenant ground-up development project located in the San Francisco – Mission Bay market.  This property is currently 92.4% leased.  Our stabilized yields on a cash and GAAP basis for this property were approximately 8.5% and 8.4%, 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 August 2011, we completed the ground-up development of 7 Triangle Drive, a 96,626 rentable square foot single-tenant building located in the Research Triangle Park market, which is currently 100% leased as of December 31, 2011.  The Stabilized Yield on a cash and GAAP basis for this property was approximately 8.5% and 9.8%, respectively.

(Tabular dollar amounts in thousands)

(Unaudited)

Summary of dispositions

In August 2011, we sold a parcel of land located in San Diego, California, for approximately $17.3 million at a gain of $46,000.  The buyer is expected to construct a building with approximately 249,000 rentable square feet, representing a sale price of approximately $70 per rentable square foot.

During the three months ended September 30, 2011, 13-15 DeAngelo Drive, a vacant 30,000 rentable square foot property, located in the suburbs of Boston, Massachusetts, met the criteria for classification as “held for sale.”  This property was occupied by a credit life science tenant through June 30, 2011.  Upon move out, a user of the building presented an offer for the purchase of the building in the three months ended September 30, 2011.  As a result, we recognized an impairment charge of approximately $1.0 million in the three months ended September 30, 2011, to adjust the carrying value to the estimated fair value less costs to sell.  In October 2011, we sold 13-15 DeAngelo Drive to that user for approximately $2.9 million, representing a sale price of approximately $97 per rentable square foot.

We currently have five buildings aggregating approximately 760,000 rentable square feet leased to FibroGen, Inc., Merck & Co., Inc., Pfizer Inc., Bayer AG, and UCSF as well as other top-tier life science entities, 219,000 rentable square feet undergoing development, and future potential buildings aggregating approximately 290,000 rentable square feet. **** Buildings in the white outline represent renderings of five future ground-up life science laboratory developments aggregating 1.9 million rentable square feet. We continue to advance various important preconstruction activities for this development site, including Building Information Modeling (3-D virtual modeling), design development, construction drawings (required for each of the five new buildings), 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 is to advance preconstruction activities in order to reduce the time to deliver a new ground-up development to a prospective tenant.

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

As of December 31, 2011, approximately 24% of our gross investment in real estate represents non-income producing assets (land, preconstruction, redevelopment, development, and projects in India and China).  Our active development and redevelopment projects represent 7% of gross investment in real estate, a significant amount of which is pre-leased and expected to be delivered over the next four to eight quarters. The completion and delivery of these projects will significantly reduce our non-income producing assets as a percentage of our gross investment in real estate. 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 investment in real estate.

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 management believes these measures provide useful information to investors about our financial condition, results of operations, or liquidity.  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 margin

EBITDA represents earnings before interest, taxes, depreciation and amortization (“EBITDA”), a non-GAAP financial measure, and is used as a supplemental measure of operating performance.  Adjusted EBITDA (“Adjusted EBITDA”) is calculated as EBITDA excluding impairments, gains or losses from sales of real estate, gains or losses on early extinguishment of debt, and net stock compensation expenses.  We use EBITDA and Adjusted EBITDA as a supplemental measure of our operating performance.  We consider Adjusted EBITDA to provide 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, impairments, gains or losses from sales of real estate, gains or losses on early extinguishment of debt, and net stock compensation expenses.  By excluding interest expense, EBITDA and Adjusted EBITDA allow investors to measure our operating performance independent of our capital structure and indebtedness and, therefore, allow for a more meaningful comparison of our operating performance to that of other companies, both in the real estate industry and in other industries.  We believe investors should consider EBITDA and Adjusted EBITDA, in conjunction with net income (the primary measure of our performance) and the other required United States generally accepted accounting principles (“GAAP”) measures of our performance, to improve their understanding of our operating results, and to make more meaningful comparisons of our performance between periods and against other companies.  EBITDA and Adjusted EBITDA have limitations as analytical tools and should be used in conjunction with our required GAAP presentations. 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 operating performance, it does not represent net income or cash flow from operations as defined by GAAP, and it should not be considered as an alternative to those indicators in evaluating operating 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 to EBITDA and Adjusted EBITDA:

Adjusted funds from operations

Adjusted Funds from Operations (“AFFO”) is a non-GAAP financial measure we believe is a useful supplemental measure of our performance.  We compute AFFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders by adding to or deducting from FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders (1) recurring and non-recurring capital expenditures required to maintain and re-tenant our properties, (2) second generation tenant improvements and leasing costs on re-tenanted and renewal space (excludes redevelopment expenditures), (3) capitalized income from development projects, (4) gains or losses on early extinguishment of debt, (5) amortization of loan fees, debt premiums/discounts and acquired above and below market leases, (6) effects of deferred rent/straight-line rent and deferred rent/straight-line rent on ground leases, (7) non-cash compensation expense related to restricted stock awards, and (8) other non-cash income or charges, including impairment charges.  AFFO is not intended to represent cash flow for the period, and is only intended to provide an additional measure of performance by adjusting the effect of certain items noted above included in FFO, as well as recurring capital expenditures and leasing costs.  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 attributable to Alexandria Real Estate Equities, Inc.’s common stockholders.  We also believe that AFFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders provides useful performance information to the investment community about our financial position as compared to other REITs since AFFO is a widely reported measure used by other REITs.  However, other REITs may use different methodologies for calculating AFFO and, accordingly, our AFFO may not be comparable to other REITs.

Annualized base rent

Annualized base rent means the annualized fixed base rental amount in effect as of December 31, 2011, 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 redevelopment and development 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 redevelopment and development 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.  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 multi-tenancy space to single-tenancy space. Development projects consist of the ground-up development of generic life science laboratory facilities. 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 will generate significant revenue and cash flows for the Company.  In accordance with GAAP, we capitalize project costs clearly related to the construction, redevelopment, and development 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, redevelopment, and development 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 being 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 (“CIP”)/current value-added projects

Active redevelopment/active development projects

A key component of our business model is our value-added redevelopment and development 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 redevelopment and development 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. 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. 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 significant pre-leasing for such space.

Projects in India and China

Projects in India and China primarily represent development opportunities and projects focused primarily on life science laboratory space for our current client tenants and other life science relationship entities. These projects focus on real estate investments with targeted returns on investment greater than returns expected in the United States.

Generic infrastructure/building improvement projects

Generic infrastructure/building improvement projects include revenue-enhancing capital spending, non-revenue-enhancing major and recurring capital expenditures, and tenant improvements.  These amounts include payments for property-related capital expenditures and tenant improvements that are recoverable from our tenants.

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.  The dividend payout ratio excludes loss on early extinguishment of debt.

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.

Earnings per share

We use income from continuing operations attributable to Alexandria Real Estate Equities, Inc.’s common stockholders as the “control number” in determining whether potential common shares, including potential common shares issuable upon conversion of our 8.00% unsecured convertible notes, are dilutive or antidilutive to earnings per share.  Pursuant to the presentation and disclosure literature on gains/losses on sales or disposals by REITs and earnings per share required by the SEC and the Financial Accounting Standards Board, gains or losses on sales or disposals by a REIT that do not qualify as discontinued operations are classified below income from discontinued operations in the income statement and included in the numerator for the computation of earnings per share for income from continuing operations.  The land parcels we sold during the three months ended December 31, 2010, and three months ended September 30, 2011, did not meet the criteria for discontinued operations since these parcels did not have any significant operations prior to disposition.  Accordingly, for the three months and year ended December 31, 2010, and the year ended December 31, 2011, we classified the $59.4 million and $46,000, respectively, of gain on sales of land parcels below income from discontinued operations, net in the consolidated income statements, and included the gain in income from continuing operations attributable to Alexandria Real Estate Equities, Inc.’s common stockholders, the “control number,” or numerator for the computation of earnings per share.

We account for unvested restricted stock awards which contain nonforfeitable rights to dividends as participating securities and include these securities in the computation of earnings per share using the two-class method.  Under the two-class method, we allocate net income after preferred stock dividends and amounts attributable to noncontrolling interests to (1) common stockholders and (2) unvested restricted stock awards based on their respective participation rights to dividends declared (or accumulated) and undistributed earnings.  Diluted earnings per share is computed using the weighted average shares of common stock outstanding determined for the basic earnings per share computation plus the effect of any dilutive securities, including the dilutive effect of stock options using the treasury stock method.

We applied the if-converted method of accounting for our 8.00% unsecured senior convertible notes (“8.00% Unsecured Convertible Notes”).  In applying the if-converted method of accounting, conversion is assumed for purposes of calculating diluted earnings per share if the effect would be dilutive to earnings per share.  If the assumed conversion pursuant to the if-converted method is dilutive, diluted earnings per share would be calculated by adding back interest charges applicable to our 8.00% Unsecured Convertible Notes to the numerator and our 8.00% Unsecured Convertible Notes would be assumed to have been converted at the beginning of the period presented (or from the date of issuance, if occurring on a date later than the date that the period begins) and the resulting incremental shares associated with the assumed conversion would be included in the denominator.  Furthermore, we assume that our 8.00% Unsecured Convertible Notes are converted for the period prior to any retirement or actual conversion if the effect of such assumed retirement or conversion would be dilutive, and any shares of common stock issued upon actual conversion are included in the denominator for the period after the date of retirement or conversion.  For all periods except the three months ended December 31, 2010, potential common shares issuable upon conversion of our 8.00% unsecured convertible notes were antidilutive to income from continuing operations per share and as such, were excluded from the computation of diluted earnings per share.

Funds from operations

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 NAREIT established the measurement tool of Funds from Operations (“FFO”).  Since its introduction, FFO has become a widely used non-GAAP financial measure among real estate investment trusts (“REITs”).  We believe that FFO is helpful to investors as an additional measure of the performance of an equity REIT.  We compute FFO in accordance with standards established by the Board of Governors of NAREIT in its April 2002 White Paper (the “White Paper”) and related implementation guidance, which may differ from the methodology for calculating FFO utilized by other equity REITs, and, accordingly, may not be comparable to such other REITs.  The White Paper defines FFO as net income (computed in accordance with GAAP), excluding gains from sales, plus real estate related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures.  Impairment write-downs of depreciable real estate are excluded from the calculation of FFO. FFO 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.

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 significant 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 significant 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.

Investment in unconsolidated real estate entity

Our investment in unconsolidated real estate entity represents our equity investment in a real estate entity that owns a land parcel supporting the ground-up development of approximately 414,000 rentable square feet in the Longwood Medical Area of Boston.

Future redevelopment

Our asset base also includes non-laboratory space (office, warehouse, and industrial space) identified for future conversion into life science laboratory space through redevelopment aggregating approximately 1.0 million rentable square feet. These spaces are currently classified in rental properties, net.

FFO per share

FFO per share (diluted) is computed using the weighted average shares of common stock outstanding determined for the basic FFO per share computation plus the effect of any dilutive securities, including the dilutive effect of stock options using the treasury stock method.  Additionally, we applied the if-converted method for our 8.00% Unsecured Convertible Notes for FFO per share separately from the if-converted analysis for earnings per share.  In applying the if-converted method, conversion is assumed for purposes of calculating FFO per share (diluted) if the effect would be dilutive to FFO per share.  If the assumed conversion pursuant to the if-converted method is dilutive, FFO per share (diluted) would be calculated by adding back interest charges applicable to our 8.00% Unsecured Convertible Notes to the numerator and our 8.00% Unsecured Convertible Notes would be assumed to have been converted at the beginning of the period presented (or from the date of issuance, if occurring on a date later than the date that the period begins) and the resulting incremental shares associated with the assumed conversion would be included in the denominator.  Furthermore, we assume that our 8.00% Unsecured Convertible Notes are converted for the period prior to any retirement or actual conversion if the effect of such assumed retirement or conversion would be dilutive, and any shares of common stock issued upon actual retirement or conversion are included in the denominator for the period after the date of retirement or conversion.  For purposes of calculating FFO per share (diluted), the if-converted method was dilutive to FFO per share (diluted) for all periods presented.

Gross assets

Gross assets 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.

Net debt

Net debt is equal to the sum of secured notes payable, unsecured line of credit, unsecured bank term loans, and unsecured convertible notes, 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 from 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 only 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 our results of operations from 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 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 table on the following page 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 period presented, properties undergoing active redevelopment and active development, 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.

Tangible non-real estate assets

Tangible non-real estate assets include the following as of each date presented:

Total tangible non-real estate assets $ 249,884 $ 237,277 $ 210,113 $ 237,805 $ 240,873

Total market capitalization

Total market capitalization is equal to the sum of outstanding shares of series C preferred stock and common stock multiplied by the related closing price at the end of each period presented, the liquidation value of the series D cumulative convertible preferred stock, and total debt (secured notes payable, unsecured line of credit, unsecured bank term loans, and unsecured convertible notes).

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, and amortization of loan 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.
