Reports

Fourth Quarter and Year Ended December 31, 2013

Financial and Operating Results

EPS – Diluted of $0.51 for 4Q13

FFO Per Share – Diluted, as Adjusted, of $1.16 for 4Q13

Total Revenues of $168.8 Million for 4Q13

NOI of $118.9 Million for 4Q13

Strong Demand in Key Cluster Submarkets Drives Record Leasing Activity

PASADENA, CA. – February 3, 2014 – Alexandria Real Estate Equities, Inc. (NYSE:ARE) today announced financial and operating results for the fourth quarter and year ended December 31, 2013.

“We are very pleased to announce our fourth quarter and year ended December 31, 2013, financial and operating results. Our per share results for the fourth quarter and year ended December 31, 2013, reflected 1) the strength of our core operations, 2) completion of significant high value Class A development projects in AAA locations in urban science and technology cluster markets, and 3) the completion of many significant and important improvements in our long-term capital structure. Monetization of significant non-income-producing land parcels (Alexandria Center™ for Science and Technology located in Mission Bay, Alexandria Center™ at Kendall Square located in Cambridge, and Alexandria Center™ for Life Science located in New York City) through lease-up and development, and through selective sales has generated significant long-term asset value. In 2012 and 2013, we sold certain non-strategic income-producing assets and land for approximately $275 million. Proceeds from these sales, including the $55 million from the sale of a land parcel in late 2013, were invested into high value/low cap rate Class A development projects with an estimated value of approximately $450 million, representing an increase of almost $175 million above the value of the properties sold. We are also pleased with the successful execution of our second 10-year unsecured bond offering in early 2013 at a rate of 3.90%. The capital generated from the sales of properties and issuance of long-term debt and common stock resulted in short-term per share dilution, improved our long-term capital structure and funded our Class A developments, among others, at Alexandria Center™ at Kendall Square located in Cambridge. We are optimistic about our ability to deliver solid and stable per share earnings growth and continue to increase long-term asset value in 2014 and beyond,” said Joel S. Marcus, Chief Executive Officer, and Founder of Alexandria Real Estate Equities, Inc.

Guidance

Based on our current view of existing market conditions and other assumptions, we have updated guidance for earnings per share – diluted and FFO per share – diluted, both amounts attributable to Alexandria’s common stockholders for the year ended December 31, 2014.  The table below provides a reconciliation of FFO per share – diluted, a non-GAAP measure, from earnings per share – diluted, the most directly comparable GAAP measure, as well as other key assumptions included in our guidance for the year ended December 31, 2014. We expect that our principal liquidity needs for the year ended December 31, 2014, will be satisfied by the following multiple sources of capital as shown in the table below.  There can be no assurance that our sources and uses of capital will not be materially higher or lower than these expectations. The key assumptions behind the sources and uses of capital 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 lease 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 under Part I and the “Risk Factors” section under Item 1A of our annual report on Form 10-K for the year ended December 31, 2012, in our subsequent quarterly reports on Form 10-Q, and in our subsequent annual report on Form 10-K for the year ended December 31, 2013.  We expect to update our forecast of sources and uses of capital on a quarterly basis.

Alexandria manages its properties through fully integrated regional and life science teams with unparalleled real estate and life science expertise. As the Landlord of Choice to the Life Science Industry^®, Alexandria is known for its high-quality and diverse client tenant base, which includes 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.

Company Profile

Alexandria Real Estate Equities, Inc. (NYSE:ARE), a self-administered and self-managed REIT, is the largest and leading REIT focused principally on owning, operating, developing, redeveloping, and acquiring high-quality, sustainable real estate for the broad and diverse life science industry. Founded in 1994, Alexandria pioneered the laboratory/office niche and has become the leading life science real estate brand and dominant market presence in the top life science clusters, including Greater Boston, the San Francisco Bay Area, San Diego, Greater New York City, Maryland, Seattle, and Research Triangle Park. Alexandria manages its properties through fully integrated regional and life science teams with unparalleled real estate and life science expertise. As the Landlord of Choice to the Life Science Industry^®, Alexandria is known for its high-quality and diverse client tenant base. Alexandria has a proven and superior track record developing Class A laboratory/office assets in AAA cluster locations adjacent to leading academic medical research centers, offering highly creative amenities that drive client tenant productivity and foster innovation, and gathering its longstanding and expansive network in the life science community. For additional information on Alexandria, please visit www.are.com.

Unique niche strategy

Alexandria’s primary business objective is to maximize stockholder value by providing its stockholders with the greatest possible total return and long-term asset value based on a multifaceted platform of internal and external growth. The key elements of our strategy include:

• A consistent focus on Class A laboratory/office assets and operations focused primarily in key urban science center campus locations in AAA life science cluster locations characterized by high barriers to entry for new landlords, high barriers to exit for client tenants, and a limited supply of available space;

• Collaborative locations adjacent to leading life science entities and research institutions that drive innovation and growth within each cluster and provide access to dense concentrations of highly educated and skilled people;

• Utilizing our deep real estate relationships in order to develop and acquire real estate;

• Drawing upon our broad and meaningful life science relationships to attract new and leading life science client tenants; and

• Solid and flexible capital structure to enable growth.

Client tenant base

The impressive quality, diversity, breadth, and depth of our significant relationships with our life science client tenants provide Alexandria with solid and stable cash flows. Alexandria’s strong life science underwriting skills and long-term life science industry relationships positively distinguish Alexandria from all other publicly traded REITs and real estate companies.

• Investment-grade client tenants represent 51% of total annualized base rent as of December 31, 2013

• Investment-grade client tenants represent 82% of Alexandria’s top 20 client tenants by ABR as of December 31, 2013

• Our ABR as of December 31, 2013, consisted of the following client tenant mix:

• 25.3% from multinational pharmaceutical companies

• 21.5% from revenue producing life science product and service, medical device, and industrial biotech companies

• 19.1% from public biotechnology companies

• 19.1% from institutional university, non-profit, and government

• 11.3% from private biotechnology companies

• 3.7% from traditional office client tenants

Executive/senior management

Alexandria’s executive and senior management team is highly experienced in the REIT industry and is the most accomplished team focused on providing high-quality, environmentally sustainable real estate; technical infrastructure; and life science and real estate development, construction, operations, and ownership expertise to the broad and diverse life science industry. Our deep and talented team has decades of life science industry experience. Alexandria’s senior management team averages over 23 years of life science and real estate experience, including over 11 years with Alexandria. Our sophisticated management team also includes regional market directors with leading reputations and longstanding relationships with the life science communities in their respective clusters. We believe that our expertise, experience, reputation, and key life science relationships provide Alexandria significant competitive advantages in attracting new business opportunities.

Same Property Performance

(Unaudited)

The charts below provide two alternative calculations of same property performance in comparison to our historical same property performance. Our reported same property performance has been based upon a pool of operating assets and completed developed and redeveloped assets to the extent that those assets were operating for the entirety of the comparable same property period presented. The two alternative calculations presented below consist of 1) same property performance for the operating portfolio excluding assets that were recently developed or redeveloped and 2) the same property performance for the operating portfolio including those assets that were either under current redevelopment or previously completed redevelopments. From 2008 through 2012, our same property performance was generally consistent in each of the three calculations. For the year ended December 31, 2013, same property performance including redevelopment properties, as shown in the table, would have been meaningfully higher than our traditional method of reporting same property performance. Same property performance including redevelopment properties will, from time to time, have significant growth in NOI as a result of the completion of the conversion of non-laboratory space (with lower NOI) to laboratory/office space (with higher NOI) through redevelopment.  We believe our traditional method of reporting same property performance is a more useful presentation since it excludes the potential significant increases in performance as a result of completion of significant redevelopment projects.

(1) Recently delivered developments and redevelopments are included in the same property data for each of the year-over-year comparison periods only if the property was operating during the entire same property period. For example, projects completed during 2011 are included in 2013 same property performance (as a percentage change over 2012).

Operating/Development Project Near-Term Value-Creation Project

Property	Alexandria Center™ at Kendall Square
Submarket/Market	Cambridge/Greater Boston
Aerial
Background	Alexandria received final approval from the City of Cambridge to develop the Alexandria Center™ at Kendall Square, a fully-integrated campus featuring four world-class laboratory/office and tech office buildings, high-quality amenities, and green space. Alexandria’s entitlement efforts resulted in an increase of 1.1 million developable square feet over the original entitlements in place at acquisition.
Near-Term Opportunity	Ground-up development of laboratory/office and tech office buildings at 50, 60, and 100 Binney Street aggregating approximately 1.0 million RSF plus residential projects aggregating 238,000 RSF. Subject to market conditions, we expect to commence development of these projects over the next one to three years as we have demand from existing tenants and demand from tenants in the market. Additionally, we anticipate financing these projects with joint venture capital. We believe the estimated investment, excluding land, to develop these buildings, with underground parking, will generally range from $650 per square foot and up.

Definitions and Other Information

(Unaudited)

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

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

The following table reconciles net income, the most directly comparable financial measure calculated and presented in accordance with GAAP, to EBITDA and Adjusted EBITDA:

	Three Months Ended												Year Ended

Adjusted EBITDA margins

We calculate Adjusted EBITDA margins by dividing Adjusted EBITDA by total revenues. Because our total revenues exclude revenues from discontinued operations, for the purposes of calculating the margin ratio, we exclude the Adjusted EBITDA generated by our discontinued operations for each period presented. We believe excluding Adjusted EBITDA for discontinued operations improves the consistency and comparability of the Adjusted EBITDA margins from period to period. The following table reconciles Adjusted EBITDA to Adjusted EBITDA – excluding discontinued operations:

Adjusted funds from operations

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) maintenance building improvements, and non-revenue-enhancing 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) stock 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 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 charges related to share-based compensation facilitates a comparison of our operations across periods and among other equity REITs without the variances caused by different valuation methodologies, the volatility of the expense (which depends on market forces outside our control), and the assumptions and the variety of award types that a company can use.  We believe that AFFO provides useful information by excluding certain items that are not representative of our core operating results because such items are dependent upon historical costs or subject to judgmental valuation inputs and the timing of our decisions.

AFFO is not intended to represent cash flow for the period, and is intended only to provide an additional measure of performance.  We believe that net income attributable to Alexandria’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).

Average cash yield

See definition of Initial Stabilized Yield (unlevered).

Capitalized interest

A key component of our business model is our value-creation development and redevelopment projects.  These programs are focused on providing high-quality generic laboratory/office space to meet the real estate requirements of and are reusable by various life science industry client tenants.  Upon completion, each value-creation 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 laboratory/office facilities.  Redevelopment projects consist of the permanent change in use of office, warehouse, and shell space into generic laboratory/office space.  We also have certain significant value-creation projects undergoing important and substantial predevelopment 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-creation projects

Current value-creation development/current redevelopment projects

A key component of our business model is our value-creation development and redevelopment projects.  These programs are focused on providing high-quality, generic, and reusable laboratory/office space to meet the real estate requirements of a wide range of client tenants in the life science industry.  Upon completion, each value-creation 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 laboratory/office facilities.  We generally will not commence new development projects for above-ground vertical construction of new laboratory/office space without first securing pre-leasing for such space except when there is significant market demand for high-quality laboratory/office facilities.  Redevelopment projects consist of the permanent change in use of office, warehouse, and shell space into generic laboratory/office space.

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’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.

Fixed charge coverage ratio

The fixed charge coverage ratio is the ratio of Adjusted EBITDA to fixed charges. This ratio is useful to investors as a supplemental measure of our ability to satisfy fixed financing obligations and preferred stock dividends.  The following table presents a reconciliation of interest expense, the most directly comparable GAAP financial measure to cash interest and fixed charges:

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 funds from operations (“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 depreciable real estate and land parcels and impairments of depreciable real estate (excluding land parcels), plus real estate related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures.  Impairments of real estate relate to decreases in the estimated fair value of real estate due to changes in general market conditions and do not necessarily reflect the operating performance of the properties during the corresponding period.  Impairments of real estate represent the 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, impairments of land parcels, impairments of investments, and deal costs, less realized gain on equity investment primarily related to one non-tenant life science entity, and the amount of such items that is allocable to our unvested restricted stock awards.  Our calculations of both FFO and FFO, as adjusted, may differ from those methodologies utilized by other equity REITs for similar performance measurements, and, accordingly, may not be comparable to those of other equity REITs.  Neither FFO nor FFO, as adjusted, should be considered as an alternative to net income (determined in accordance with GAAP) as an indication of financial performance, or to cash flows from operating activities (determined in accordance with GAAP) as a measure of liquidity, nor are they indicative of the availability of funds for our cash needs, including funds available to make distributions.

Future value-creation projects

Land held for future development

All predevelopment efforts have been advanced to appropriate stages and no further predevelopment 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, except when there is significant market demand for high-quality laboratory facilities.

Land undergoing predevelopment activities (additional CIP)

Land undergoing predevelopment activities is classified as construction in progress and is undergoing activities prior to commencement of vertical construction of aboveground building improvements.  We generally will not commence ground-up development of any parcels undergoing predevelopment activities without first securing pre-leasing for such space, except when there is significant market demand for high-quality laboratory facilities.  If vertical aboveground construction is not initiated at completion predevelopment activities, the land parcel will be classified as land held for future development.  Our objective with predevelopment is to reduce the time it takes to deliver projects to prospective client tenants.  The largest project included in land undergoing predevelopment consists of our 1.2 million developable square feet at the Alexandria Center™ at Kendall Square in East Cambridge, Massachusetts.

We are required to capitalize project costs, including interest, property taxes, insurance, and other costs directly related and essential to the development or construction of a project during periods when activities necessary to prepare an asset for its intended use are in progress.  Predevelopment costs generally include the following activities prior to commencement of vertical construction:

Ÿ Traditional preconstruction costs including entitlement, design, construction drawings, Building Information Modeling (3-D virtual modeling), budgeting, sustainability and energy optimization reviews, permitting, and planning for all aspects of the project.

Ÿ Site and infrastructure construction costs including belowground site work, utility connections, land grading, drainage, egress and regress access points, foundation, and other costs to prepare the site for vertical construction of aboveground building improvements. For example, site and infrastructure costs for the 1.2 million RSF primarily related to 50, 60, and 100 Binney Street of the Alexandria Center™ at Kendall Square are classified as predevelopment prior to commencement of vertical construction.

Gross assets

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

Initial stabilized yield (unlevered)

Initial stabilized yield is calculated as the quotient of the estimated amounts of NOI and our investment in the property.  Our initial stabilized yield excludes the impact of leverage.  Our cash rents related to our value-creation projects are expected to increase over time and our average cash yields are expected, in general, to be greater than our initial stabilized yields on a cash basis.  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.

Ÿ Initial stabilized yield - cash basis: reflects cash rents at the stabilization date after initial rental concessions, if any, have elapsed.

Ÿ Initial stabilized yield - GAAP basis: reflects cash rents, including contractual rent escalations and any rent concessions over the term(s) of the lease(s), calculated on a straight-line basis.

Average cash yield reflects cash rents, including contractual rent escalations after initial rental concessions have elapsed, calculated on a straight-line basis.

Net debt

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

NOI

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

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

Same property comparisons

As a result of changes within our total property portfolio during the comparative periods presented, including assets acquired, properties placed into redevelopment and development, and projects delivered into operations from redevelopment and development, the consolidated total rental revenues, tenant recoveries and rental operating expenses in our operating results can show significant changes 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 entirety of the comparative periods presented separate from properties acquired subsequent to the first day in the earliest comparable period presented, properties that underwent development or redevelopment at any time during the comparative periods, 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. The following table reconciles same properties to total properties for the year ended December 31, 2013:

Stabilized occupancy date

The stabilized occupancy date represents the estimated date on which the project is expected to reach occupancy of 95% or greater.

Total market capitalization

Total market capitalization is equal to the sum of outstanding shares of series E cumulative convertible 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 and total debt.

Unencumbered NOI as a percentage of total NOI

Unencumbered NOI as a percentage of total NOI is a non-GAAP financial measure that we believe is useful to investors as a performance measure of our results of operations of our unencumbered real estate assets, as it reflects primarily those income and expense items that are incurred at the unencumbered property level.  We use unencumbered NOI as a percentage of total NOI in order to assess our compliance with our financial covenants under our debt obligations because the measure serves as a proxy for a financial measure under such debt obligations.  Unencumbered NOI is derived from assets classified in continuing operations 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 NOI for periods prior to the three months ended December 31, 2013, has been reclassified to conform to current period presentation related to discontinued operations.

Weighted average interest rate for capitalization

The weighted average interest rate required for calculating capitalization of interest 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 swap 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 swap agreements, and the amount of loan fee amortization.

The following table presents the weighted average interest rate for capitalization:

	Three Months Ended
