Attachment 17

AvalonBay Communities, Inc.
Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms

This release, including its attachments, contains certain non-GAAP financial measures and other terms. The definition and calculation of these non-GAAP financial measures and other terms may differ from the definitions and methodologies used by other REITs and, accordingly, may not be comparable. The non-GAAP financial measures referred to below should not be considered an alternative to net income as an indication of our performance. In addition, these non-GAAP financial measures do not represent cash generated from operating activities in accordance with GAAP and therefore should not be considered as an alternative measure of liquidity or as indicative of cash available to fund cash needs.

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 companys real estate between periods or as compared to different companies. A reconciliation of FFO to Net Income is as follows (dollars in thousands):


	Q4			Q4			Full Year			Full Year
	2009			2008			2009			2008

Net income attributable to the Company	$	32,394		$	2,123		$	155,647		$	411,487

Attachment 17 (continued)

Projected FFO, as provided within this release in the Companys 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 first quarter and full year 2010 to the range provided for Projected EPS (diluted) is as follows:


	Low			High
	range			range

Projected EPS (diluted) Q1 10	$	1.06		$	1.12
Projected depreciation (real estate related)		0.69			0.71
Projected gain on sale of operating communities		(0.86	)		(0.90	)

Projected FFO per share (diluted) Q1 10	$	0.89		$	0.93


Projected EPS (diluted) Full Year 2010	$	1.60		$	1.85
Projected depreciation (real estate related)		2.75			3.00

Projected FFO per share (diluted) Full Year 2010	$	3.60		$	3.85

(1)		For purposes of non-routine classification, abandoned pursuits includes costs expensed by the Company for individual pursuits in excess of $1,000 in a given quarter.

(2)		Includes the Companys promoted interest of $3,894 in joint venture, and the Companys pro-rata portion of an impairment charge on a community in an unconsolidated joint venture of $2,600.

(3)		Non-routine item was included in the Companys full year 2009 Outlook provided in November 2009. The Companys outlook included $2,900 for federal excise tax.

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

Attachment 17 (continued)

property management and other indirect operating expenses, investments and investment management expenses, expensed development and other pursuit costs, net interest expense, general and administrative expense, joint venture income, net income or expense attributable to noncontrolling interests, 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):

NOI as reported by the Company does not include the operating results from discontinued operations (i.e., assets sold during the period January 1, 2008 through December 31, 2009). A reconciliation of NOI from communities sold or classified as discontinued operations to net income for these communities 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 managements estimate, as of the date of this release (or as of the date of the buyers 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 below, 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 buyers valuation. Projected stabilized rental revenue represents managements estimate of projected gross potential (based on leased rents for occupied homes and Market Rents, as defined below, 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 Companys share of the Total Capital Cost of each community, based on its percentage ownership.

Management believes that Projected NOI of the Development Communities, on an aggregated weighted average basis, assists investors in understanding managements estimate of the likely impact on operations of the Development 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 is complex, impractical to develop, and may not be meaningful. Projected NOI of these communities is not a projection of the Companys overall financial performance or cash flow. There can be no assurance that the communities under development 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 full year ended December 31, 2009 as well as prior years activities is presented on Attachment 14.

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 attributable to the Company before interest income and expense, income taxes, depreciation and amortization.

A reconciliation of EBITDA and a calculation of Interest Coverage for the fourth quarter of 2009 are as follows (dollars in thousands):


Net income attributable to the Company	$	32,394
Interest expense, net		42,107
Interest expense (discontinued operations)
Depreciation expense		55,392
Depreciation expense (discontinued operations)		1,200

EBITDA	$	131,093


EBITDA from continuing operations	$	90,106
EBITDA from discontinued operations		40,987

EBITDA	$	131,093


EBITDA from continuing operations	$	90,106
Land gains		(4,589	)


EBITDA from continuing operations, excluding land gains	$	85,517


Interest charges	$	42,107


Interest coverage (1)		2.0


(1)		Adjusted to remove the impact of the October 2009 tender offer, interest coverage is 2.7 times.

Attachment 17 (continued)

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 on Attachment 13, 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 managements estimate of projected rental revenue minus projected operating expenses before interest, income taxes (if any), depreciation, amortization and extraordinary items. For this purpose, managements 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 Companys 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 Companys 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.

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 Companys 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 full year December 31, 2009 is as follows (dollars in thousands):

Attachment 17 (continued)


NOI for Established Communities	$	387,127
NOI for Other Stabilized Communities		81,517
NOI for Development/Redevelopment Communities		77,378

Total NOI generated by real estate assets		546,022
NOI on encumbered assets		192,389

NOI on unencumbered assets		353,633


Unencumbered NOI		65	%

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 below, as of the beginning of the prior year. Therefore, for 2009, Established Communities are consolidated communities that have Stabilized Operations as of January 1, 2008 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.

Development Communities are communities that are under construction during the current year. These communities may be partially or fully complete and operating.

Redevelopment Communities are communities where the Company owns a majority interest and where substantial redevelopment is in progress or is planned to begin during the current year. Redevelopment is considered substantial when capital invested during the reconstruction effort is expected to exceed either $5,000,000 or 10% of the communitys pre-development basis.

Average Rental Rates are calculated by the Company as rental revenue in accordance with GAAP, divided by the weighted average number of occupied apartment homes.

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 communitys gross revenue.

Market Rents as reported by the Company are based on the current market rates set by the managers of the Companys communities based on their experience in renting their communities apartments and publicly available market data. Trends in market rents for a region as reported by others could vary. Market Rents for a period are based on the average Market Rents during that period and do not reflect any impact for cash concessions.

Non-Revenue Generating Capex represents capital expenditures that will not directly result in revenue earnings or expense savings.

Stabilized/Restabilized Operations is defined as the earlier of (i) attainment of 95% physical occupancy or (ii) the one-year anniversary of completion of development or redevelopment.

Average Rent per Home, as calculated for certain Development and Redevelopment Communities in lease-up, reflects (i) actual average leased rents for those apartments leased through the end of the quarter net of estimated stabilized concessions, (ii) estimated market rents net of comparable concessions for all unleased apartments and (iii) includes actual and estimated other rental revenue. For Development and Redevelopment Communities not yet in lease-up, Average Rent per Home reflects managements projected rents.

Development Rights are development opportunities in the early phase of the development process for which the Company either has an option to acquire land or enter into a leasehold interest, for which the Company is the buyer under a long-term conditional contract to purchase land or where the Company owns land to develop a new community. The Company capitalizes related predevelopment costs incurred in pursuit of new developments for which future development is probable.
