In addition, the Company closed an associated 4.0%, fixed rate construction loan of $2,500,000.

Preferred Stock Redemption

On October 15, 2008, the Company exercised its option to redeem all 4,000,000 outstanding shares of its 8.70% Series H Cumulative Redeemable Preferred Stock for $100,701,000. The repayment amount includes the redemption value of the outstanding shares of $25 per share and accrued but unpaid dividends through the redemption date. The Company will record a non-cash charge for deferred offering expenses of approximately $3,500,000 in the fourth quarter of 2008 related to this redemption.

Dividend Requirements

As a REIT, the Company is subject to certain dividend distribution requirements in relation to taxable income to avoid paying federal income taxes at the corporate level. During the first nine months of 2008, the Company sold ten communities, and expects the execution of additional sales prior to year end. These completed and projected sales will cause the Company’s 2008 taxable income to exceed qualifying distributions expected to be made in the normal course of business. To meet its distribution requirements and avoid paying federal income tax, the Company anticipates that a special, nonrecurring dividend in the range of approximately $1.75 per share to $1.85 per share would be required to be declared sometime before September 2009. The exact amount will depend on the final amount of taxable income (principally gains recognized from property sales) during 2008. The timing of the special dividend has not yet been determined. Depending on the amount and timing of the dividend, the Company may incur an excise tax for 2008 of between $0 and $9,000,000 pertaining to cumulative unpaid capital gain distributions related to 2008 property sales.

Fourth Quarter and Full Year 2008 Financial Outlook

For the fourth quarter of 2008, the Company expects EPS in the range of $1.42 to $1.46. The Company expects EPS for the full year 2008 to be in the range of $6.61 to $6.65. The full year 2008 range has been adjusted to reflect changes in the Company’s disposition program.

The Company expects Projected FFO per share in the range of $1.25 to $1.29 for the fourth quarter of 2008 and Projected FFO per share for the full year 2008 to be between $5.03 and $5.07. The Company’s estimates for fourth quarter and full year 2008 do not include the potential excise tax described above.

The Company expects to release its fourth quarter 2008 earnings on February 4, 2009 after the market closes. The Company expects to hold a conference call on February 5, 2009 at 1:00 PM EST to discuss the fourth quarter and full year 2008 results.

You can identify these forward-looking statements by the Company’s use of words such as “expects,” “plans,” “estimates,” “projects,” “intends,” “believes,” “outlook” and similar expressions that do not relate to historical matters. Actual results may differ materially from those expressed or implied by the forward-looking statements as a result of risks and uncertainties, which include the following: adverse capital and credit market conditions may affect our access to various sources of capital and/or cost of capital, which may affect our business activities, earnings and common stock price, among other things; changes in local employment conditions, demand for apartment homes, supply of competitive housing products, and other economic conditions may result in lower than expected occupancy and/or rental rates and adversely affect the profitability of our communities; increases in costs of materials, labor or other expenses may result in communities that we develop or redevelop failing to achieve expected profitability; delays in completing development, redevelopment and/or lease-up may result in increased financing and construction costs and may delay and/or reduce the profitability of a community; debt and/or equity financing for development, redevelopment or acquisitions of communities may not be available or may not be available on favorable terms; we may be unable to obtain, or experience delays in obtaining, necessary governmental permits and authorizations; or we may abandon development or redevelopment opportunities for which we have already incurred costs.

Definitions and Reconciliations

Non-GAAP financial measures and other capitalized terms, as used in this earnings release, are defined and further explained on Attachment 14, “Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms.” Attachment 14 is included in the full earnings release available at the Company’s website at http://www.avalonbay.com/earnings. This wire distribution includes only definitions and reconciliations of the following Non-GAAP financial measures:

FFO is determined based on a definition adopted by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”). FFO is calculated by the Company as net income or loss computed in accordance with GAAP, adjusted for gains or losses on sales of previously depreciated operating communities, extraordinary gains or losses (as defined by GAAP), cumulative effect of a change in accounting principle and depreciation of real estate assets, including adjustments for unconsolidated partnerships and joint ventures. Management generally considers FFO to be an appropriate supplemental measure of operating performance because, by excluding gains or losses related to dispositions of previously depreciated operating communities and excluding real estate depreciation (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO can help one compare the operating performance of a company’s real estate between periods or as compared to different companies. A reconciliation of FFO to net income is as follows (dollars in thousands):



	Q3			Q3			YTD			YTD
	2008			2007			2008			2007 (1)
Net income	$	233,581		$	128,769		$	409,364		$	226,340

Average shares outstanding — diluted		77,580,847			80,024,714			77,516,222			80,195,908
EPS — diluted	$	2.98		$	1.58		$	5.20		$	2.74

FFO per common share — diluted	$	1.28		$	1.19		$	3.78		$	3.47


(1)		FFO per common share — diluted includes $0.01 for the nine months ended September 30, 2007 related to the sale of a land parcel.

Projected FFO, as provided within this release in the Company’s outlook, is calculated on a basis consistent with historical FFO, and is therefore considered to be an appropriate supplemental measure to projected net income from projected operating performance. A reconciliation of the range provided for Projected FFO per share (diluted) for the fourth quarter and full year 2008 to the range provided for projected EPS (diluted) is as follows:



	Low			High
	range			range
Projected EPS (diluted) — Q4 08	$	1.42		$	1.46
Projected depreciation (real estate related)		0.66			0.68
Projected gain on sale of operating communities		(0.83	)		(0.85	)

Projected FFO per share (diluted) — Q4 08	$	1.25		$	1.29


Projected EPS (diluted) — Full Year 2008	$	6.61		$	6.65
Projected depreciation (real estate related)		2.60			2.64
Projected gain on sale of operating communities		(4.18	)		(4.22	)

Projected FFO per share (diluted) — Full Year 2008	$	5.03		$	5.07

NOI is defined by the Company as total property revenue less direct property operating expenses (including property taxes), and excludes corporate-level income (including management, development and other fees), corporate-level property management and other indirect operating expenses, investments and investment management, net interest expense, general and administrative expense, joint venture income, minority interest expense, depreciation expense, gain on sale of real estate assets and income from discontinued operations. The Company considers NOI to be an appropriate supplemental measure to net income of operating performance of a community or communities because it helps both investors and management to understand the core operations of a community or communities prior to the allocation of corporate-level property management overhead or general and administrative costs. This is more reflective of the operating performance of a community, and allows for an easier comparison of the operating performance of single assets or groups of assets. In addition, because prospective buyers of real estate have different overhead structures, with varying marginal impact to overhead by acquiring real estate, NOI is considered by many in the real estate industry to be a useful measure for determining the value of a real estate asset or groups of assets.

A reconciliation of NOI (from continuing operations) to net income, as well as a breakdown of NOI by operating segment, is as follows (dollars in thousands):

Projected NOI, as used within this release for certain development and redevelopment communities and in calculating the Initial Year Market Cap Rate for dispositions, represents management’s estimate, as of the date of this release (or as of the date of the buyer’s valuation in the case of dispositions), of projected stabilized rental revenue minus projected stabilized operating expenses. For development and redevelopment communities, Projected NOI is calculated based on the first year of Stabilized Operations, as defined in the full earnings release, following the completion of construction. In calculating the Initial Year Market Cap Rate, Projected NOI for dispositions is calculated for the first twelve months following the date of the buyer’s valuation. Projected stabilized rental revenue represents management’s estimate of projected gross potential (based on leased rents for occupied homes and Market Rents, as defined in the full earnings release, for vacant homes) minus projected economic vacancy and adjusted for concessions. Projected stabilized operating expenses do not include interest, income taxes (if any), depreciation or amortization, or any allocation of corporate-level property management overhead or general and administrative costs. The weighted average Projected NOI as a percentage of Total Capital Cost is weighted based on the Company’s share of the Total Capital Cost of each community, based on its percentage ownership.

Management believes that Projected NOI of the development and redevelopment communities, on an aggregated weighted average basis, assists investors in understanding management’s estimate of the likely impact on operations of the development and redevelopment communities when the assets are complete and achieve stabilized occupancy (before allocation of any corporate-level property management overhead, general and administrative costs or interest expense). However, in this release the Company has not given a projection of NOI on a company-wide basis. Given the different dates and fiscal years for which NOI is projected for these communities, the projected allocation of corporate-level property management overhead, general and administrative costs and interest expense to communities under development or redevelopment is complex, impractical to develop, and may not be meaningful. Projected NOI of these communities is not a projection of the Company’s overall financial performance or cash flow. There can be no assurance that the communities under development or redevelopment will achieve the Projected NOI as described in this release.

Rental Revenue with Concessions on a Cash Basis is considered by the Company to be a supplemental measure to rental revenue in conformity with GAAP to help investors evaluate the impact of both current and historical concessions on GAAP based rental revenue and to more readily enable comparisons to revenue as reported by other companies. In addition, rental revenue (with concessions on a cash basis) allows an investor to understand the historical trend in cash concessions.

A reconciliation of rental revenue from Established Communities in conformity with GAAP to rental revenue (with concessions on a cash basis) is as follows (dollars in thousands):

Economic Gain is calculated by the Company as the gain on sale in accordance with GAAP, less accumulated depreciation through the date of sale and any other non-cash adjustments that may be required under GAAP accounting. Management generally considers Economic Gain to be an appropriate supplemental measure to gain on sale in accordance with GAAP because it helps investors to understand the relationship between the cash proceeds from a sale and the cash invested in the sold community. The Economic Gain for each of the communities presented is estimated based on their respective final settlement statements. A reconciliation of Economic Gain to gain on sale in accordance with GAAP for both the nine months ended September 30, 2008 as well as prior years’ activities is presented in the full earnings release.

Interest Coverage is calculated by the Company as EBITDA from continuing operations, excluding land gains and gain on the sale of investments in real estate joint ventures, divided by the sum of interest expense, net, and preferred dividends. Interest Coverage is presented by the Company because it provides rating agencies and investors an additional means of comparing our ability to service debt obligations to that of other companies. EBITDA

is defined by the Company as net income before interest income and expense, income taxes, depreciation and amortization.

A reconciliation of EBITDA and a calculation of Interest Coverage for the third quarter of 2008 are as follows (dollars in thousands):



Net income	$	233,581
Interest expense, net		28,364
Interest expense (discontinued operations)		236
Depreciation expense		49,397
Depreciation expense (discontinued operations)		958


EBITDA	$	312,536


EBITDA from continuing operations	$	125,938
EBITDA from discontinued operations		186,598


EBITDA	$	312,536


EBITDA from continuing operations	$	125,938

Interest expense, net		28,364
Dividends attributable to preferred stock		2,175


Interest charges		30,539


Interest coverage		4.1

Total Capital Cost includes all capitalized costs projected to be or actually incurred to develop the respective development or redevelopment community, or development right, including land acquisition costs, construction costs, real estate taxes, capitalized interest and loan fees, permits, professional fees, allocated development overhead and other regulatory fees, all as determined in accordance with GAAP. For redevelopment communities, Total Capital Cost excludes costs incurred prior to the start of redevelopment when indicated. With respect to communities where development or redevelopment was completed in a prior or the current period, Total Capital Cost reflects the actual cost incurred, plus any contingency estimate made by management. Total Capital Cost for communities identified as having joint venture ownership, either during construction or upon construction completion, represents the total projected joint venture contribution amount. For joint ventures not in construction as presented in the full earnings release, Total Capital Cost is equal to gross real estate cost.

Initial Year Market Cap Rate is defined by the Company as Projected NOI of a single community for the first 12 months of operations (assuming no repositioning), less estimates for non-routine allowance of approximately $200 — $300 per apartment home, divided by the gross sales price for the community. Projected NOI, as referred to above, represents management’s estimate of projected rental revenue minus projected operating expenses before interest, income taxes (if any), depreciation, amortization and extraordinary items. For this purpose, management’s projection of operating expenses for the community includes a management fee of 3.0% — 3.5%. The Initial Year Market Cap Rate, which may be determined in a different manner by others, is a measure frequently used in the real estate industry when determining the appropriate purchase price for a property or estimating the value for a property. Buyers may assign different Initial Year Market Cap Rates to different communities when determining the appropriate value because they (i) may project different rates of change in operating expenses and capital expenditure estimates and (ii) may project different rates of change in future rental revenue due to different estimates for changes in rent and occupancy levels. The weighted average Initial Year Market Cap Rate is weighted based on the gross sales price of each community.

Unleveraged IRR on sold communities refers to the internal rate of return calculated by the Company considering the timing and amounts of (i) total revenue during the period owned by the Company and (ii) the gross sales price net of selling costs, offset by (iii) the undepreciated capital cost of the communities at the time of sale and (iv) total direct operating expenses during the period owned by the Company. Each of the items (i), (ii), (iii) and (iv) are calculated in accordance with GAAP.

The calculation of Unleveraged IRR does not include an adjustment for the Company’s general and administrative expense, interest expense, or corporate-level property management and other indirect operating expenses. Therefore, Unleveraged IRR is not a substitute for net income as a measure of our performance. Management believes that the Unleveraged IRR achieved during the period a community is owned by the Company is useful because it is one indication of the gross value created by the Company’s acquisition, development or redevelopment, management and sale of a community, before the impact of indirect expenses and Company overhead. The Unleveraged IRR achieved on the communities as cited in this release should not be viewed as an indication of the gross value created with respect to other communities owned by the Company, and the Company does not represent that it will achieve similar Unleveraged IRRs upon the disposition of other communities. The weighted average Unleveraged IRR for sold communities is weighted based on all cash flows over the holding period for each respective community, including net sales proceeds.

Leverage is calculated by the Company as total debt as a percentage of Total Market Capitalization. Total Market Capitalization represents the aggregate of the market value of the Company’s common stock, the market value of the Company’s operating partnership units outstanding (based on the market value of the Company’s common stock), the liquidation preference of the Company’s preferred stock and the outstanding principal balance of the Company’s debt. Management believes that Leverage can be one useful measure of a real estate operating company’s long-term liquidity and balance sheet strength, because it shows an approximate relationship between a company’s total debt and the current total market value of its assets based on the current price at which the Company’s common stock trades. Changes in Leverage also can influence changes in per share results. A calculation of Leverage as of September 30, 2008 is as follows (dollars in thousands):



Total debt	$	3,429,440

Common stock		7,589,140
Preferred stock		100,000
Operating partnership units		6,301
Total debt		3,429,440

Total market capitalization		11,124,881


Debt as % of capitalization		30.8	%

Because Leverage changes with fluctuations in the Company’s stock price, which occur regularly, the Company’s Leverage may change even when the Company’s earnings, interest and debt levels remain stable. Investors should also note that the net realizable value of the Company’s assets in liquidation is not easily determinable and may differ substantially from the Company’s Total Market Capitalization.

Unencumbered NOI as calculated by the Company represents NOI generated by real estate assets unencumbered by either outstanding secured debt or land leases (excluding land leases with purchase options that were put in place for governmental incentives or tax abatements) as a percentage of total NOI generated by real estate assets. The Company believes that current and prospective unsecured creditors of the Company view Unencumbered NOI as one indication of the borrowing capacity of the Company. Therefore, when reviewed together with the Company’s Interest Coverage, EBITDA and cash flow from operations, the Company believes that investors and creditors view Unencumbered NOI as a useful supplemental measure for determining the financial flexibility of an entity. A calculation of Unencumbered NOI for the nine months ended September 30, 2008, for assets owned at September 30, 2008, is as follows (dollars in thousands):



NOI for Established Communities	$	310,276
NOI for Other Stabilized Communities		55,699
NOI for Development/Redevelopment Communities		56,399
NOI for discontinued operations		18,437

Total NOI generated by real estate assets		440,811
NOI on encumbered assets		93,328

NOI on unencumbered assets		347,483


Unencumbered NOI		78.8	%

Established Communities are identified by the Company as communities where a comparison of operating results from the prior year to the current year is meaningful, as these communities were owned and had Stabilized Operations, as defined in the full earnings release, as of the beginning of the prior year. Therefore, for 2008, Established Communities are consolidated communities that have Stabilized Operations as of January 1, 2007 and are not conducting or planning to conduct substantial redevelopment activities within the current year. Established Communities do not include communities that are currently held for sale or planned for disposition during the current year.

Economic Occupancy is defined as total possible revenue less vacancy loss as a percentage of total possible revenue. Total possible revenue is determined by valuing occupied units at contract rates and vacant units at market rents. Vacancy loss is determined by valuing vacant units at current market rents. By measuring vacant apartments at their Market Rents, Economic Occupancy takes into account the fact that apartment homes of different sizes and locations within a community have different economic impacts on a community’s gross revenue.
