ITEM 2.02 RESULTS OF OPERATIONS AND FINANCIAL CONDITION AND
ITEM 7.01 REGULATION FD DISCLOSURE

On April 18, 2005, we disclosed a supplemental analyst package in connection with our earnings conference call for the first quarter of 2005. A copy of the supplemental analyst package is attached hereto as Exhibit 99.1. This section and the attached exhibit are provided under Items 2.02 and 7.01 of Form 8-K and are furnished to, but not filed with, the Securities and Exchange Commission.

Forward Looking Statements

Some of the information included in the supplemental analyst package and the conference call to be held in connection therewith contains forward-looking statements, such as those related to development and renovation projects (including stabilization dates, square feet at stabilization or completion, and total investment amounts), lease expirations and future business plans (such as property divestitures and financings), which are made pursuant to the safe-harbor provisions of Section 21E of the Securities Exchange Act of 1934, as amended, and Section 27A of the Securities Act of 1933, as amended. Because these forward-looking statements involve risks and uncertainties, there are important factors that could cause our actual results to differ materially from those in the forward-looking statements, and you should not rely on the forward-looking statements as predictions of future events. The events or circumstances reflected in forward-looking statements might not occur. You can identify forward-looking statements by the use of forward-looking terminology such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “approximately,” “intends,” “plans,” “pro forma,” “estimates” or “anticipates” or the negative of these words and phrases or similar words or phrases. You can also identify forward-looking statements by discussions of strategy, plans or intentions. Forward-looking statements are necessarily dependent on assumptions, data or methods that may be incorrect or imprecise and we may not be able to realize them. We caution you not to place undue reliance on forward-looking statements, which reflect our analysis only and speak only as of the date of this report or the dates indicated in the statements. We assume no obligation to update or supplement forward-looking statements. The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements: defaults on or non-renewal of leases by tenants, increased interest rates and operating costs, our failure to obtain necessary outside financing, difficulties in identifying properties to acquire and in effecting acquisitions, our failure to successfully integrate acquired properties and operations, our failure to divest properties we have contracted to sell or to timely reinvest proceeds from any divestitures, risks and uncertainties affecting property development and construction (including construction delays, cost overruns, our inability to obtain necessary permits and public opposition to these activities), our failure to qualify and maintain our status as a real estate investment trust, environmental uncertainties, risks related to natural disasters, financial market fluctuations, changes in real estate and zoning laws, risks related to doing business internationally and increases in real property tax rates. Our success also depends upon economic trends generally, including interest rates, income tax laws, governmental regulation, legislation, population changes and

certain other matters discussed under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Business Risks” and elsewhere in our annual report on Form 10-K for the year ended December 31, 2004.

REPORTING DEFINITIONS 24 Acquisition/non-recurring capex includes immediate building improvements that were 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. Also includes incremental building improvements and leasing costs that are incurred in an effort to substantially increase the revenue potential of an existing building. AMB's share of total debt-to-AMB's share of total book capitalization is calculated using the following definitions: AMB's share of total debt is the pro rata portion of the total debt based on the Company's percentage of equity interest in each of the consolidated or unconsolidated ventures holding the debt. AMB's share of total book capitalization is defined as the Company's share of total debt plus minority interests to preferred unitholders and limited partnership unitholders plus stockholders' equity. AMB's share of total debt-to-AMB's share of 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 the Company's percentage of equity interest in each of the consolidated or unconsolidated ventures holding the debt. The Company's definition of "total market capitalization" is total debt plus preferred equity liquidation preferences plus market equity. The Company's definition of "AMB's share of total market capitalization" is the Company's share of total debt plus preferred equity liquidation preferences plus market equity. The Company's definition of "market equity" is the total number of outstanding shares of the Company's common stock and common limited partnership units multiplied by the closing price per share of its common stock as of March 31, 2005. AMB's share of total market capitalization is defined by the Company as the Company's share of total debt plus preferred equity liquidation preferences plus market equity. 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. Completion/Stabilization is generally defined as properties that are 90% leased or properties for which we have held a certificate of occupancy or building has been substantially complete for at least 12 months. Development and renovation GAAP yields are calculated from estimated annual NOI following occupancy stabilization (including straight-line rents) divided by the estimated total investment, including Development Alliance Partner(r) earnouts (if triggered by stabilization) and associated carrying costs. Fixed charge coverage is adjusted EBITDA divided by total interest expense (including capitalized interest) plus preferred dividends and distributions. Interest coverage is adjusted EBITDA divided by total GAAP interest expense. Market equity is defined by the Company as the total number of outstanding shares of the Company's common stock and common limited partnership units multiplied by the closing price per share of its common stock as of March 31, 2005. Occupancy percentage represents the percentage of total rentable square feet owned, which is leased, including month-to-month leases, as of the date reported. Space is considered leased when the tenant has either taken physical or economic occupancy. Percentage pre-leased represents the percentage of signed leases only. Preferred is defined by the Company, with respect to its capitalization ratios, as preferred equity liquidation preferences. Renovation projects represent projects where the acquired buildings are less than 75% leased and require significant capital expenditures (generally more than 10% - 25% of acquisition cost) to bring the buildings up to operating standards and stabilization (generally 90% occupancy). Recurring capital expenditures represents non-incremental building improvements and leasing costs required to maintain current revenues. Recurring capital expenditures do not include acquisition capital that was taken into consideration when underwriting the purchase of a building or which are incurred to bring a building up to "operating standard." Rent increases on renewals and rollovers are calculated as the difference, weighted by square feet, of the net ABR due the first month after a term commencement date and the net ABR due the last month prior to the termination date 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 the first in the unit (first generation) and there is no prior lease for comparison, then it is excluded from this calculation. Same store NOI growth is the change in the NOI (excluding straight-line rents) of the same store properties from the prior year reporting period to the current year reporting period. Same store properties include all properties that were 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, 2003. Same store pool includes Park One parking lot in Los Angeles, California. 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. Square feet owned represents 100% of the square footage of properties either owned directly by the Company or which the Company has a controlling interest in (e.g. consolidated joint ventures) and excludes square footage of development properties prior to completion. Stabilized GAAP cap rates rates are calculated as NOI, including straight-line rents, 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, all due diligence and closing costs, SFAS 141 adjustments, planned immediate capital expenditures, leasing costs necessary to achieve stabilization and, if applicable, any estimated costs required to buy-out AMB's joint venture partners. Tenant retention is the square footage of all leases renewed by existing tenants divided by the square footage of all expiring and renewed 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 the Company as total debt plus preferred equity liquidation preferences plus market equity. Value-added conversion project represents the repurposing of land or a building site for more valuable uses and may include such activities as rezoning, redesigning, reconstructing and retenanting.

SUPPLEMENTAL FINANCIAL MEASURES DISCLOSURES Adjusted EBITDA. The Company uses adjusted earnings before interest, tax, depreciation and amortization, or adjusted EBITDA, to measure both its operating performance and liquidity. The Company considers adjusted EBITDA to provide investors relevant and useful information because it permits fixed income investors to view income from its operations on an unleveraged basis before the effects of non-cash depreciation and amortization expense. By excluding interest expense, adjusted EBITDA allows investors to measure the Company'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. The Company 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, the Company believes that adjusted EBITDA helps fixed income and equity investors to analyze its ability to meet debt service obligations and to make quarterly preferred share and unit distributions. Management uses adjusted EBITDA in the same manner as the Company expects investors to when measuring the Company'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 and unit distributions. The Company believes investors should consider adjusted EBITDA, in conjunction with net income (the primary measure of the Company's performance) and the other required GAAP measures of its performance and liquidity, to improve their understanding of the Company's operating results and liquidity, and to make more meaningful comparisons of the performance of its assets between periods and as against other companies. By excluding interest, taxes, depreciation and amortization when assessing the Company's financial performance, an investor is assessing the earnings generated by the Company's operations, but not taking into account the eliminated expenses incurred in connection with such operations. As a result, adjusted EBITDA has limitations as an analytical tool and should be used in conjunction with the Company's required GAAP presentations. Adjusted EBITDA does not reflect the Company'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 the Company'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, the Company's computation of adjusted EBITDA may not be comparable to EBITDA reported by other companies. Company's share of total debt. The Company'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 or unconsolidated ventures holding the debt. The Company 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. The Company'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. Interest coverage. The Company uses interest coverage to measure its liquidity. The Company considers interest coverage to provide investors relevant and useful information because it permits fixed income investors to measure the Company's ability to meet its interest payments on outstanding debt. The Company's computation of interest coverage may not be comparable to interest coverage reported by other companies. Fixed charge coverage. The Company uses fixed charge coverage to measure its liquidity. The Company considers fixed charge coverage to provide investors relevant and useful information because it permits fixed income investors to measure the Company's ability to meet its interest payments on outstanding debt, make distributions to its preferred unitholders and pay dividends to its preferred shareholders. The Company's computation of fixed charge coverage may not be comparable to fixed charge coverage reported by other companies. Funds From Operations ("FFO"). The Company believes that net income, as defined by GAAP, is the most appropriate earnings measure. However, the Company considers funds from operations, or FFO, as defined by NAREIT, to be a useful supplemental measure of its operating performance. FFO is defined as net income, calculated in accordance with GAAP, less gains (or losses) from dispositions of real estate held for investment purposes and real estate-related depreciation, and adjustments to derive the Company's pro rata share of FFO of consolidated and unconsolidated joint ventures. Further, the Company does not adjust FFO to eliminate the effects of non-recurring charges. The Company believes that FFO, as defined by NAREIT, is a meaningful supplemental measure of its operating performance because historical cost accounting for real estate assets in accordance with 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, NAREIT created FFO as a supplemental measure of operating performance for real estate investment trusts that excludes historical cost depreciation and amortization, among other items, from net income, as defined by GAAP. The Company believes that the use of FFO, combined with the required 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. The Company considers FFO to be a useful measure 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, FFO 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 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 the Company's liquidity or operating performance. FFO also does not consider the costs associated with capital expenditures related to the Company's real estate assets nor is FFO necessarily indicative of cash available to fund the Company's future cash requirements. Further, the Company's computation of FFO may not be comparable to FFO reported by other real estate investment trusts that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently than the Company does. Net Operating Income ("NOI"). Net operating income is defined as rental revenue, including reimbursements, less property operating expenses, which excludes depreciation, amortization, general and administrative expenses and interest expense. The Company considers NOI to be an appropriate 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. 25
