Acquisition Cost includes estimated acquisition capital expenditures. Estimated acquisition capital expenditures include immediate building improvements that are taken into consideration when underwriting the purchase of a building or which are incurred to bring a building up to operating standard or to stabilization and incremental building improvements and leasing costs that are incurred in an effort to substantially increase the revenue potential of an existing building.

Adjusted EBITDA. AMB uses adjusted earnings before interest (including the amount of capitalized interest deducted from the determination of development gains), tax, depreciation and amortization, impairment charges, and non-development gains, or adjusted EBITDA, to measure both its operating performance and liquidity. AMB considers adjusted EBITDA to provide investors relevant and useful information because it permits investors to view income from its operations on an unleveraged basis before the effects of tax, non-cash depreciation and amortization expense or non-development gains. By excluding interest expense, adjusted EBITDA allows investors to measure AMB’s operating performance independent of its capital structure and indebtedness and, therefore, allows for a more meaningful comparison of its operating performance between quarters as well as annual periods and to compare its operating performance to that of other companies, both in the real estate industry and in other industries. AMB considers adjusted EBITDA to be a useful supplemental measure for reviewing its comparative performance with other companies because, by excluding non-cash depreciation expense, adjusted EBITDA can help the investing public compare the performance of a real estate company to that of companies in other industries. As a liquidity measure, AMB believes that adjusted EBITDA helps investors to analyze its ability to meet debt service obligations and to make quarterly preferred share dividends and unit distributions. Management uses adjusted EBITDA when measuring AMB’s operating performance and liquidity; specifically when assessing its operating performance, and comparing that performance to other companies, both in the real estate industry and in other industries, and when evaluating its ability to meet debt service obligations and to make quarterly preferred share dividends and unit distributions. AMB believes investors should consider adjusted EBITDA, in conjunction with net income (the primary measure of AMB’s performance) and the other required GAAP measures of its performance and liquidity, to improve their understanding of AMB’s operating results and liquidity, and to make more meaningful comparisons of its performance between periods and as against other companies. By excluding interest, taxes, depreciation and amortization, and non-development gains when assessing AMB’s financial performance, an investor is assessing the earnings generated by AMB’s operations, but not taking into account the eliminated expenses or non-development gains incurred in connection with such operations. As a result, adjusted EBITDA has limitations as an analytical tool and should be used in conjunction with AMB’s required GAAP presentations. Adjusted EBITDA does not reflect AMB’s historical cash expenditures or future cash requirements for working capital, capital expenditures or contractual commitments. Adjusted EBITDA also does not reflect the cash required to make interest and principal payments on AMB’s outstanding debt. While adjusted EBITDA is a relevant and widely used measure of operating performance and liquidity, 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, AMB’s computation of adjusted EBITDA may not be comparable to EBITDA reported by other companies.

The following table reconciles adjusted EBITDA from net (loss) income for the three months ended March 31, 2009 and 2008 (dollars in thousands):

AMB’s share of calculations for certain financial measures represent the pro-rata portion of the applicable financial measure based on AMB’s percentage of equity interest in each of the consolidated and unconsolidated co-investment ventures accounted for in the applicable financial measure. AMB believes that “AMB’s share of” calculations are meaningful and useful supplemental measures, which enable both management and investors to assess the operations, earnings and growth of AMB in light of AMB’s ownership interest in its joint ventures and to compare the applicable measure to that of other companies. In addition, it allows for a more meaningful comparison of the applicable measure to that of other companies that do not consolidate any of their joint ventures. “AMB’s share of” calculations are not intended to reflect actual liability should there be a default under loans or a liquidation of the joint ventures. AMB’s computation of “AMB’s share of” measures may not be comparable to that of other real estate companies, as they may use different methodologies for calculating these measures.

AMB’s share of Other Balance Sheet Items. AMB believes that balance sheet information based on GAAP provides the most appropriate information about financial position. However, AMB considers balance sheet information reported on an owned and managed basis (such as AMB’s share of cash and cash equivalents, AMB’s share of accounts receivable (net) and other assets, AMB’s share of deferred rents receivable and deferred financing costs (net), and AMB’s share of accounts payable and other liabilities) to be useful supplemental measures to help the investors better understand AMB’s operating performance. See Reporting Definitions for definitions of “owned and managed” and “AMB’s share of.” AMB believes that AMB’s share of balance sheet items on an owned and managed basis helps management and investors make a comprehensive assessment of AMB’s total real estate portfolio and provides a better understanding of AMB’s operating activities. While such information is helpful to the investor, it does not provide balance sheet information as defined by GAAP and is not a true alternative to such GAAP measurements. Further, AMB’s computation of its share of balance sheet items on an owned and managed basis may not be comparable to that of other real estate companies, as they may use different methodologies for calculating these measures.

AMB’s share of total debt. AMB’s share of total debt is the pro rata portion of the total debt based on its percentage of equity interest in each of the consolidated and unconsolidated joint ventures holding the debt. AMB believes that its share of total debt is a meaningful supplemental measure, which enables both management and investors to analyze its leverage and to compare its leverage to that of other companies. In addition, it allows for a more meaningful comparison of its debt to that of other companies that do not consolidate their joint ventures. AMB’s share of total debt is not intended to reflect its actual liability should there be a default under any or all of such loans or a liquidation of the joint ventures. See Capitalization Detail for a reconciliation of total debt and AMB’s share of total debt.

AMB’s share of total debt-to-AMB’s share of total assets is calculated using the following definitions: AMB’s share of total debt is the pro rata portion of the total debt based on AMB’s percentage of equity interest in each of the consolidated and unconsolidated joint ventures holding the debt. AMB’s share of total assets is the pro rata portion of total assets based on AMB’s percentage of equity interest in each of the consolidated and unconsolidated joint ventures holding the assets.

AMB’s share of total debt-to-total market capitalization is calculated using the following definitions: AMB’s share of total debt is the pro rata portion of the total debt based on AMB’s percentage of equity interest in each of the consolidated and unconsolidated joint ventures holding the debt. AMB’s definition of “total market capitalization” is AMB’s share of total debt plus preferred equity liquidation preferences plus market equity. AMB’s definition of “market equity” is the total number of outstanding shares of AMB’s common stock and common limited partnership units multiplied by the closing price per share of its common stock as of the period end.

Annualized base rent (ABR) is calculated as monthly base rent (cash basis) per the lease, as of a certain date, multiplied by 12. If free rent is granted, then the first positive rent value is used. Leases denominated in foreign currencies are translated using the currency exchange rate at period end.

Assets Under Management is AMB’s estimate of the value of the real estate it wholly owns or manages through its consolidated and unconsolidated co-investment ventures or for clients of AMB Capital Partners. Assets under management is calculated by adding the co-investment venture partner’s or client’s share of the carrying value of its real estate investment to AMB’s share of total market capitalization.

Average occupancy percentage represents the daily weighted occupancy of the total rentable square feet leased, including month-to-month leases, divided by total rentable square feet. Space is considered leased when the tenant has either taken physical or economic occupancy.

Carrying value is the sum of the most recent valuation of real estate investments plus subsequently incurred capital expenditures. Generally, each real estate investment is valued once a year.

Cash-basis NOI. Cash-basis NOI is defined as NOI less straight line rents and amortization of lease intangibles. AMB considers cash-basis NOI to be an appropriate and useful supplemental performance measure because cash basis NOI reflects the operating performance of the real estate portfolio excluding the effects of non-cash adjustments and provides a better measure of actual cash basis rental growth for a year-over-year comparison. However, cash-basis NOI should not be viewed as an alternative measure of financial performance since it does not reflect general and administrative expenses, interest expenses, depreciation and amortization costs, capital expenditures and leasing costs, or trends in development and construction activities that could materially impact results from operations. Further, cash-basis NOI may not be comparable to that of other real estate investment trusts, as they may use different methodologies for calculating cash-basis NOI.

For a reconciliation of NOI from net income for the three months ended March 31, 2009, refer to the SS NOI definition. The following table reconciles AMB’s share of cash-basis NOI from NOI for the quarter ended March 31, 2009 (dollars in thousands):

(1)		Excludes $3.8 million of interest expense on loans from co-investment venture partners.

Co-investment venture partner’s share of calculations for certain financial measures represent the pro-rata portion of the applicable financial measure based on AMB’s co-investment venture partners’ percentage of equity interest in each of the consolidated or unconsolidated co-investment ventures accounted for in the applicable financial measure.

Co-investment venture partner’s (or co-investor’s) share of debt is the co-investment venture partner’s pro-rata portion of total debt.

Co-investment venture partner’s (or co-investor’s) share of equity is the pro-rata portion of the co-investment venture partner’s share of carrying value less the co-investment venture partner’s share of debt.

Completion/Stabilization is generally defined as properties that are 90% leased or properties that have been substantially complete for at least 12 months.

Development activities include ground-up development, redevelopments, renovations, land sales and value-added conversions.

Development margin is calculated as contribution value or disposition price less closing costs, minus estimated total investment and any deferred rents, taxes or third party promotes before any deferrals on contributions, divided by the estimated total investment.

Estimated FFO by Business. Estimated FFO by Business is FFO generated by AMB’s Real Estate Operations, Development and Private Capital business. Estimated Development and Private Capital FFO was determined by reducing Development Profits, net of taxes, and Private Capital revenues by their respective estimated share of general and administrative expenses, also defined as overhead. Development’s and Private Capital’s estimated allocation of total general and administrative expenses was based on their respective percentage of actual direct general and administrative expenses incurred. Estimated Real Estate Operations FFO represents total AMB FFO less estimated FFO attributable to Development and Private Capital. Management believes estimated FFO by business line is a useful supplemental measure of its operating performance because it helps the investing public compare the operating performance of AMB’s respective businesses to other companies’ comparable businesses. Further, AMB’s computation of FFO by business line may not be comparable to that reported by other real estate investment trusts as they may use different methodologies in computing such measures.

Estimated investment capacity is AMB’s estimate of the gross real estate which could be acquired through the use of its equity commitments from co-investment venture partners plus AMB’s funding obligations and estimated debt capitalization.

Estimated total investment represents total estimated cost of development, renovation, or expansion, including initial acquisition costs, prepaid ground leases, buildings, and associated carry costs. Estimated total investments are based on current forecasts and are subject to change. Non-U.S. Dollar investments are translated to U.S. Dollars using the exchange rate at period end.

Estimated yields on development projects are calculated from estimated annual cash NOI following occupancy stabilization divided by the estimated total investment. Yields exclude value added conversion projects and are calculated on an after-tax basis for international projects.

Fixed charge coverage. Fixed charge coverage is defined as Adjusted EBITDA divided by fixed charges. Fixed charges consist of interest expense less joint venture partner’s share of interest expense, including amortization of finance costs and debt premiums, from continuing and discontinued operations, AMB’s share of interest expense from unconsolidated joint venture debt, capitalized interest, preferred unit distributions and preferred stock dividends. AMB uses fixed charge coverage to measure its liquidity. AMB believes fixed charge coverage is relevant and useful to investors because it permits fixed income investors to measure AMB’s ability to meet its interest payments on outstanding debt, make distributions to its preferred unitholders and pay dividends to its preferred shareholders. AMB’s computation of fixed charge coverage may not be comparable to fixed charge coverage reported by other companies.

Funds From Operations (“FFO”), Funds From Operations Per Share and Unit (“FFOPS”) and FFO, excluding impairment charges (together with FFO and FFOPS, the “FFO Measures”). AMB believes that net income, as defined by U.S. GAAP, is the most appropriate earnings measure. However, AMB considers funds from operations, or FFO, FFO per share and unit, or FFOPS, and FFO, excluding impairment charges, to be useful supplemental measures of its operating performance. AMB defines FFOPS as FFO per fully diluted weighted average share of AMB’s common stock and operating partnership units. AMB calculates FFO as net income available to common stockholders, calculated in accordance with U.S. GAAP, less gains (or losses) from dispositions of real estate held for investment purposes and real estate-related depreciation, and adjustments to derive AMB’s pro rata share of FFO of consolidated and unconsolidated joint ventures.

AMB includes the gains from development, including those from value-added conversion projects, before depreciation recapture, as a component of FFO. AMB believes that value-added conversion dispositions are in substance land sales and as such should be included in FFO, consistent with the real estate investment trust industry’s long standing practice to include gains on the sale of land in FFO. However, AMB’s interpretation of FFO or FFOPS may not be consistent with the views of others in the real estate investment trust industry, who may consider it to be a divergence from the NAREIT definition, and may not be comparable to FFO or FFOPS reported by other real estate investment trusts that interpret the current NAREIT definition differently than AMB does. In connection with the formation of a joint venture, AMB may warehouse assets that are acquired with the intent to contribute these assets to the newly formed venture. Some of the properties held for contribution may, under certain circumstances, be required to be depreciated under U.S. GAAP. If this circumstance arises, AMB intends to include in its calculation of FFO gains or losses related to the contribution of previously depreciated real estate to joint ventures. Although such a change, if instituted, will be a departure from the current NAREIT definition, AMB believes such calculation of FFO will better reflect the value created as a result of the contributions. To date, AMB has not included gains or losses from the contribution of previously depreciated warehoused assets in FFO.

In addition to presenting FFO as described above, AMB presents FFO, excluding impairment charges. AMB calculates FFO, excluding impairment charges, as FFO less impairment charges and adjustments to derive AMB’s share of impairment charges from consolidated and unconsolidated joint ventures. To the extent that the book value of a land parcel or development asset exceeded the fair market value of a property, based on its intended holding period, a non-cash impairment charge was recognized for the shortfall. The impairment charges were principally a result of increases in estimated capitalization rates and deterioration in market conditions that adversely impacted values. Although difficult to predict, these charges may be recurring given the uncertainty of the current economic climate and its adverse effects on the real estate markets. While not infrequent or unusual in nature, these charges are subject to market fluctuations that can have inconsistent effects on AMB’s results of operations. The economics underlying these charges reflect market conditions in the short-term but can obscure the value of AMB’s long-term investment decisions and strategies. Management believes FFO, excluding impairment charges, is significant and useful to both it and its investors because it more appropriately reflects the value and strength of AMB’s business model and its potential performance isolated from the volatility of the current economic environment. However, in addition to the limitations of FFO Measures generally discussed below, FFO, excluding impairment charges, does not present a comprehensive measure of AMB’s financial condition and operating performance. This measure is a modification of the NAREIT definition of

FFO and should not be considered a replacement of FFO as AMB defines it or used as an alternative to net income or cash as defined by U.S. GAAP.

AMB believes that the FFO Measures are meaningful supplemental measures of its operating performance because historical cost accounting for real estate assets in accordance with U.S. GAAP implicitly assumes that the value of real estate assets diminishes predictably over time, as reflected through depreciation and amortization expenses. However, since real estate values have historically risen or fallen with market and other conditions, many industry investors and analysts have considered presentation of operating results for real estate companies that use historical cost accounting to be insufficient. Thus, the FFO Measures are supplemental measures of operating performance for real estate investment trusts that exclude historical cost depreciation and amortization, among other items, from net income available to common stockholders, as defined by U.S. GAAP. AMB believes that the use of the FFO Measures, combined with the required U.S. GAAP presentations, has been beneficial in improving the understanding of operating results of real estate investment trusts among the investing public and making comparisons of operating results among such companies more meaningful. AMB considers the FFO Measures to be useful measures for reviewing comparative operating and financial performance because, by excluding gains or losses related to sales of previously depreciated operating real estate assets and real estate depreciation and amortization, the FFO Measures can help the investing public compare the operating performance of a company’s real estate between periods or as compared to other companies. While FFO and FFOPS are relevant and widely used measures of operating performance of real estate investment trusts, the FFO Measures do not represent cash flow from operations or net income as defined by U.S. GAAP and should not be considered as alternatives to those measures in evaluating AMB’s liquidity or operating performance. The FFO Measures also do not consider the costs associated with capital expenditures related to AMB’s real estate assets nor are the FFO Measures necessarily indicative of cash available to fund AMB’s future cash requirements. Management compensates for the limitations of the FFO Measures by providing investors with financial statements prepared according to U.S. GAAP, along with this detailed discussion of the FFO Measures and a reconciliation of the FFO Measures to net income available to common stockholders, a U.S. GAAP measurement.

See Consolidated Statements of Funds from Operations for a reconciliation of FFO from net income available to common stockholders.

Impairment charges represent the write down of assets due to estimated fair value being lower than carry value.

Interest coverage. Interest coverage is defined as adjusted EBITDA divided by AMB’s share of interest expense which consists of consolidated interest expense less joint venture partner’s share of interest expense, including amortization, from continuing and discontinued operations and AMB’s share of interest expense from unconsolidated joint venture debt. AMB uses interest coverage to measure its liquidity. AMB believes interest coverage is relevant and useful to investors because it permits investors to measure AMB’s ability to meet its interest payments on outstanding debt.

Joint Ventures are all joint ventures, including Co-Investment Ventures, with real estate developers, other real estate operators, or institutional investors where AMB may or may not: have control, act as the manager and/or developer, earn asset management distributions or fees, or earn incentive distributions or promoted interests. In certain cases, AMB might provide development, leasing, property management and/or accounting services for which it may receive market compensation.

Joint venture partner’s share of calculations for certain financial measures represent the pro-rata portion of the applicable financial measure based on AMB’s joint venture partners’ percentage of equity interest in each of the consolidated or unconsolidated joint ventures accounted for in the applicable financial measure.

Market equity is defined as the total number of outstanding shares of AMB’s common stock and common limited partnership units multiplied by the closing price per share of its common stock at period end.

Net Asset Value (“NAV”). AMB believes NAV is a useful supplemental measure of its operating performance because it enables both management and investors to analyze the fair value of its business. An assessment of the fair value of a business involves estimates and assumptions and can be performed using various methods. AMB has presented certain financial measures related to its business that it believes may be useful to the investing public in calculating its NAV but has not presented any specific methodology nor provided any guidance on assumptions or estimates that should be used in the calculation.

Net Operating Income (“NOI”). Net operating income is defined as rental revenue (as calculated in accordance with GAAP), including reimbursements, less property operating expenses, which excludes depreciation, amortization, general and administrative expenses and interest expense. AMB considers NOI to be an appropriate and useful supplemental performance measure because NOI reflects the operating performance of the real estate portfolio. However, NOI should not be viewed as an alternative measure of financial performance since it does not reflect general and administrative expenses, interest expense, depreciation and amortization costs, capital expenditures and leasing costs, or trends in development and construction activities that could materially impact results from operations. Further, NOI may not be comparable to that of other real estate investment trusts, as they may use different methodologies for calculating NOI. See same store net operating income for reconciliation of NOI from net income.

Occupancy percentage at period end represents the percentage of total rentable square feet leased, including month-to-month leases, divided by total rentable square feet at period end. Space is considered leased when the tenant has either taken physical or economic occupancy.

Owned and managed is defined by AMB as assets in which AMB has at least a 10% ownership interest, is the property or asset manager, and which it intends to hold for the long-term.

Owned and Managed Supplemental Cash Flow Information. AMB believes that cash flow information based on GAAP provides the most appropriate cash flow information. However, AMB considers cash flow information reported on an owned and managed basis (such as straight-line rents and amortization of lease intangibles, AMB’s share of straight-line rents and amortization of lease intangibles, gross lease termination fees, net lease termination fees, AMB’s share of net lease termination fees, tenant improvements, lease commissions and other lease costs, building improvements, Co-investment partners’ share of capital expenditures and AMB’s share of recurring capital expenditures) to be useful supplemental measures to help the investors better understand AMB’s operating performance and cash flow. See Reporting Definitions for definitions of “owned and managed”, “AMB’s share of” and “Co-investment venture partners’ share of”. AMB believes that owned and managed cash flow information helps management and investors make a comprehensive assessment of the cash flow of AMB’s total real estate portfolio and provides a better understanding of AMB’s operating performance and activities. While owned and managed supplemental cash flow information is helpful to the investor, it does not provide cash flow information as defined by GAAP and are not true alternatives to such GAAP measurements. Further, AMB’s computation of owned and managed supplemental cash flow information may not be comparable to that of other real estate companies, as they may use different methodologies for calculating these measures.

Percent pre-leased represents the executed lease percentage of total square feet as of the reporting data.

Preferred, with respect to the capitalization ratios, is defined as preferred equity liquidation preferences.

Renovation projects represent projects where the acquired buildings are less than 75% leased and require significant capital expenditures (generally ranging from 10% — 25% of acquisition cost) to bring the buildings up to operating standards and stabilization (generally 90% leased).

Redevelopment projects represent those buildings that require significant capital expenditures (generally more than 25% of acquired cost or existing basis) to bring the buildings up to operating standards and stabilization (generally 90% leased).

Recurring capital expenditures represents non-incremental building improvements and leasing costs required to maintain current revenues. Recurring capital expenditures do not include estimated acquisition capital expenditures which were taken into consideration when underwriting the purchase of a building or which are incurred to bring a building up to operating standards.

Rent changes on renewals and rollovers are calculated as the difference, weighted by square feet, of the net ABR due the first month of a term commencement and the net ABR due the last month of the former tenant’s term. If free rent is granted, then the first positive full rent value is used as a point of comparison. The rental amounts exclude base stop amounts, holdover rent and premium rent charges. If either the previous or current lease terms are under 12 months, then they are excluded from this calculation. If the lease is first generation or there is no prior lease for comparison, then it is excluded from this calculation.

Same Store Net Operating Income and Cash-basis SS NOI (“SS NOI”). AMB believes that net income, as defined by GAAP, is the most appropriate earnings measure. However, AMB considers SS NOI to be a useful supplemental measure of our operating performance for properties that are considered part of the same store pool. In deriving SS NOI, AMB defines NOI as rental revenues, including reimbursements, less property operating expenses, both of which are calculated in accordance with GAAP. Property operating expenses exclude depreciation, amortization, general and administrative expenses and interest expense. AMB defines Cash-basis SS NOI to also exclude straight line rents and amortization of lease intangibles. AMB considers SS NOI to be an appropriate and useful supplemental performance measure because it reflects the operating performance of the real estate portfolio excluding effects of non-cash adjustments and provides a better measure of actual cash basis rental growth for a year-over-year comparison. In addition, AMB believes that SS NOI helps investors compare the operating performance of AMB’s real estate as compared to other companies. While SS NOI is a relevant and widely used measure of operating performance of real estate investment trusts, it does not represent cash flow from operations or net income as defined by GAAP and should not be considered as an alternative to those measures in evaluating our liquidity or operating performance. SS NOI also does not reflect general and administrative expenses, interest expenses, depreciation and amortization costs, capital expenditures and leasing costs, or trends in development and construction activities that could materially impact our results from operations. Further, AMB’s computation of SS NOI may not be comparable to that of other real estate companies, as they may use different methodologies for calculating SS NOI.

Cash-basis same-store NOI	$	89,926		$	90,496


(1)		Non-cash adjustments include straight line rents and amortization of lease intangibles for the same store pool only.

Same store NOI growth is the change in the NOI (excluding straight-line rents and amortization of lease intangibles) of the same store pool from the prior year reporting period to the current year reporting period.

Same store pool includes all properties that are owned as of the end of both the current and prior year reporting periods and excludes development properties for both the current and prior reporting periods. The same store pool is set annually and excludes properties purchased and developments stabilized after December 31, 2007.

Second generation TIs and LCs per square foot are total tenant improvements, lease commissions and other leasing costs incurred during leasing of second generation space divided by the total square feet leased. Costs incurred prior to leasing available space are not included until such space is leased. Second generation space excludes newly developed square footage or square footage vacant at acquisition.

Stabilized cap rates are calculated as cash NOI stabilized to market occupancy (generally 95%) divided by total acquisition cost. The total acquisition cost basis includes the initial purchase price, the effects of marking assumed debt to market, buyer’s due diligence and closing costs, lease intangible adjustments, estimated acquisition capital expenditures and leasing costs necessary to achieve stabilization.

Tenant retention is the square footage of all leases rented by existing tenants divided by the square footage of all expiring and rented leases during the reporting period, excluding the square footage of tenants that default or buy-out prior to expiration of their lease, short-term tenants and the square footage of month-to-month leases.

Total market capitalization is defined by AMB as AMB’s share of total debt plus preferred equity liquidation preferences plus market equity (unless otherwise noted).

Value-added conversion projects represent the repurposing of industrial properties to a higher and better use, including office, residential, retail, research & development or manufacturing. Activities required to prepare the property for conversion to a higher and better use may include such activities as rezoning, redesigning, reconstructing and retenanting. The sales price of the value added conversion project is generally based on the underlying land value based on its ultimate use and as such, little to no residual value is ascribed to the industrial building(s).
