AVALONBAY COMMUNITIES, INC. ANNOUNCES

FIRST QUARTER 2015 OPERATING RESULTS

(Arlington, VA)  AvalonBay Communities, Inc. (NYSE: AVB) (the “Company”) reported today Net Income Attributable to Common Stockholders for the quarter ended March 31, 2015 of $208,144,000. This resulted in Earnings per Share – diluted (“EPS”) of $1.56 for the three months ended March 31, 2015, compared to $1.09 per share for the comparable period of 2014, an increase of 43.1%.

The increase in EPS for the three months ended March 31, 2015 over the prior year period is due primarily to an increase in real estate sales and related gains, an increase in joint venture income, and an increase in Net Operating Income (“NOI”) from newly developed and existing operating communities.

Funds from Operations attributable to common stockholders - diluted (“FFO”) per share for the three months ended March 31, 2015 increased 14.6% to $1.88 from $1.64 for the comparable period of 2014. FFO per share adjusted for non-routine items as detailed in the Definitions and Reconciliations of this release ("Core FFO" per share) increased by 7.4% to $1.75 for the three months ended March 31, 2015 over the prior year period.

The following table compares the Company’s actual results for FFO per share and Core FFO per share for the first quarter 2015 to its January 2015 outlook:

First Quarter 2015 Results
Comparison to January 2015 Outlook

Interest, overhead and other	0.02			0.02
Q1 2015 per share reported results	$	1.88		$	1.75
(1) Represents the mid-point of the Company's January 2015 outlook.
(2) Includes $0.02 of operating costs related to severe winter storms in the Company's Northeast markets.
(3) Primarily due to the timing of expected settlement proceeds.

Commenting on the Company’s results, Tim Naughton, Chairman and CEO, said, "Our first quarter results reflect sustained strength in apartment fundamentals during the winter months and position us well for the upcoming peak leasing season. Looking ahead, we expect favorable

apartment demand and NOI from development lease-up activity to drive healthy Core FFO growth throughout the balance of the year."

Operating Results for the Quarter Ended March 31, 2015 Compared to the Prior Year Period

For the Company, including discontinued operations, total revenue increased by $41,713,000, or 10.4%, to $442,367,000. This increase is primarily due to growth in revenue from development communities and growth in Established Community revenue noted below. 

For Established Communities, rental revenue increased 4.3% due to an increase in average rental rates. If the Company were to include current and previously completed redevelopment communities in its Established Communities portfolio, the increase in Established Communities' rental revenue would have been 4.4%. Total revenue for Established Communities increased $14,392,000 to $342,325,000. Operating expenses for Established Communities increased $2,563,000, or 2.5%, to $105,324,000. The Company’s Established Communities' operating expenses for the three months ended March 31, 2015 include $1,088,000 related to excess and unusual snow removal and other costs from severe winter storms in the Company's Northeast markets. NOI for Established Communities increased $11,829,000, or 5.3%, to $237,001,000.

The following table reflects the percentage changes in rental revenue, operating expenses and NOI for Established Communities for the first quarter of 2015 compared to the first quarter of 2014:

Q1 2015 Compared to Q1 2014
	Rental Revenue

Development Activity

During the three months ended March 31, 2015, the Company engaged in the following development activity:

The Company completed the development of three communities:

• Avalon West Chelsea/AVA High Line, located in New York, NY;

• Avalon Alderwood I, located in Lynnwood, WA; and

• AVA Little Tokyo, located in Los Angeles, CA.

These three communities contain an aggregate of 1,357 apartment homes and were constructed for an aggregate Total Capital Cost of $452,100,000.

The Company started the construction of two communities: Avalon Alderwood II, located in Lynnwood, WA; and Avalon Hunt Valley, located in Hunt Valley, MD. These communities will contain a total of 456 apartment homes when completed and will be developed for an aggregate estimated Total Capital Cost of $100,100,000.

The Company acquired four land parcels for development for an aggregate investment of $361,150,000, which includes the development right on the Upper West Side of Manhattan discussed in the Company's February 2, 2015 press release. The Company has started, or anticipates starting, construction of apartment communities on these land parcels during the next 18 months.

The Company added three development rights. If developed as expected, these development rights will contain a total of 910 apartment homes and will be developed for an aggregate estimated Total Capital Cost of $426,000,000.

The projected Total Capital Cost of overall development rights increased to $3.3 billion at March 31, 2015 from $3.2 billion at December 31, 2014.

Disposition Activity

During the three months ended March 31, 2015, the Company sold Avalon on Stamford Harbor, a wholly-owned community located in Stamford, CT. Avalon on Stamford Harbor contains 323 apartment homes and a marina containing 74 boat slips, and was sold for $115,500,000 and an initial year market cap rate of 5.1%, resulting in a gain in accordance with GAAP of $70,936,000 and an Economic Gain of $48,616,000. Avalon on Stamford Harbor yielded an unleveraged IRR of 11.9%over an investment period of14.5years.

Liquidity and Capital Markets

At March 31, 2015, the Company did not have any borrowings outstanding under its $1,300,000,000 unsecured credit facility, and had $297,716,000 in unrestricted cash and cash in escrow.

The Company’s annualized Net Debt-to-Adjusted EBITDA for the first quarter of 2015 was 5.9 times. 

In March 2015, the Company drew the final $50,000,000 available under its $300,000,000 variable rate unsecured term loan (the "Term Loan"), which matures in March 2021.

During September 2014, the Company entered into a forward contract to sell 4,500,000 shares of common stock for an initial forward price of $151.74 per share, net of offering fees and discounts (the "Forward"). The sales price and proceeds achieved by the Company will be determined on the date or dates of settlement, with adjustments during the term of the contract for the Company’s dividends as well as for a daily interest factor that varies with changes in the Fed Funds rate. The Company has not sold any shares of common stock under the Forward. Settlement of the Forward will occur on one or more dates not later than September 8, 2015.

Unconsolidated Real Estate Investments

The Company received $20,680,000 from the joint venture partner associated with MVP I, LLC, the entity that owns Avalon at Mission Bay North II, upon agreement with the partner to modify the joint venture agreement to eliminate the Company's promoted interest for future return calculations and associated distributions. Prospectively, earnings and distributions will be based on the Company's 25.0% equity interest in the venture.

During the three months ended March 31, 2015, AvalonBay Value Added Fund II, L.P. ("Fund II"), a private discretionary real estate investment vehicle in which the Company holds an equity interest of approximately 31.3%, sold one community containing 776 apartment homes for a sales price of $117,000,000. The Company's share of the gain in accordance with GAAP was $9,660,000.

Casualty Losses

In January 2015, a fire occurred at the Company's Avalon at Edgewater apartment community located in Edgewater, New Jersey ("Edgewater"). Edgewater consisted of two residential buildings. One building, which contained 240 apartment homes, suffered a total loss. During the three months ended March 31, 2015, the Company recognized a casualty loss from the write-off of the net book value of the fixed assets destroyed by the fire. The write-off, coupled with additional incident expenses, was substantially offset by third-party insurance proceeds received during the three months ended March 31, 2015, resulting in a net casualty loss of $793,000 for the three months ended March 31, 2015.

During the three months ended March 31, 2015, several of the Company’s communities in its Northeast markets incurred property and casualty damage from severe winter storms, in addition to the incremental operating expenses discussed elsewhere in this release. The Company has recorded a casualty loss of $4,195,000 associated with these damages.

Second Quarter 2015 Financial Outlook

For the second quarter of 2015, the Company expects EPS in the range of $1.03 to $1.07, and expects Projected FFO per share to be in the range of $1.92 to $1.96. Adjusting for non-routine items as detailed in the Definitions and Reconciliations of this release, the Company expects Projected Core FFO per share for the second quarter of 2015 to be in the range of $1.80 to $1.84. The Company's financial outlook does not include any potential casualty gain associated with additional insurance proceeds anticipated related to Edgewater, as the amount and timing of such proceeds are uncertain.

Forward-Looking Statements

This release, including its Attachments, contains forward-looking statements, within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.  These forward-looking statements, which you can identify by the Company’s use of words such as “expects,” “plans,” “estimates,” “anticipates,” “projects,” “intends,” “believes,” “outlook” and similar expressions that do not relate to historical matters, are based on the Company’s expectations, forecasts and assumptions at the time of this release, which may not be realized and involve risks and uncertainties that cannot be predicted accurately or that might not be anticipated. These could cause actual results to differ materially from those expressed or implied by the forward-looking statements. Risks and uncertainties that might cause such differences include the following, among others: the Company's expectations and assumptions as of the date of this release regarding insurance coverage, lender payoff and refinancing requirements, potential uninsured loss amounts and on-going investigations resulting from the Avalon at Edgewater fire, as well as the ultimate cost and timing of replacing the Edgewater building and achieving stabilized occupancy in the event that the Company chooses to rebuild this community, are subject to change and could materially affect the Company's current expectations regarding the impact of the fire and related loss on the Company's financial condition and results of operations; we may abandon development or redevelopment opportunities for which we have already incurred costs; 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; 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; expenses may result in communities that we

Copyright © 2015 AvalonBay Communities, Inc. All Rights Reserved

develop or redevelop failing to achieve expected profitability; our assumptions concerning risks relating to our  lack of control of joint ventures and our abilities to successfully dispose of certain assets may not be realized; our assumptions and expectations in our financial outlook may prove to be too optimistic; the expected proceeds from settlement of the Forward are subject to adjustment for changes in the Fed Funds rate and the amount of dividends we pay on our common stock, and our receipt of settlement proceeds assumes that we will settle the Forward by physical delivery. Additional discussions of risks and uncertainties that could cause actual results to differ materially  from those expressed or implied by the forward-looking statements appear in the Company’s filings with the Securities and Exchange Commission, including the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014 under the heading  “Risk Factors” and under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Forward-Looking Statements” and in subsequent quarterly reports on Form 10-Q.

Definitions and Reconciliations

Non-GAAP financial measures and other capitalized terms, as used in this earnings release, are defined and further explained on Attachment 13, “Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms.” Attachment 13 is included in the full earnings release available at the Company’s website athttp://www.avalonbay.com/earnings. This wire distribution includes only definitions and reconciliations of the following non-GAAP financial measures:

Core FFO is the Company's FFO as adjusted for the non-routine items outlined in the following table (dollars in thousands, except per share data):

	Q1			Q1
	2015			2014
FFO, actual	$	250,577		$	212,845
Non-Routine Items
Joint venture gains and costs (1)	(2,002		)	90
Acquisition costs	878			12
Joint venture promote	(20,680		)	(2,195		)
Casualty and impairment loss (2)	3,240			—
Severance related costs	1,648			—
Other non-routine items	(11		)	—
Core FFO	$	233,650		$	210,752
Core FFO per share	$	1.75		$	1.63
Average shares outstanding - diluted	133,175,773			129,629,557
(1) Composed primarily of the Company's proportionate share of gains, losses and operating results for joint ventures formed with Equity Residential as part of the Archstone acquisition.
(2) Composed primarily of expenses and actual and estimated lost revenue resulting from the fire at Edgewater.

Economic Gain (Loss)is calculated by the Company as the gain (loss) 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 (Loss) to be an appropriate supplemental measure to gain (loss) 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 (Loss) for each of the communities presented is estimated based on their respective final settlement statements.  A reconciliation of Economic Gain (Loss) to gain on sale in accordance with GAAP for the quarter ended March 31, 2015 as well as prior years’ activities is presented in the full earnings release.

Economic Occupancy (“Ec Occ”)is defined as total possible revenue less vacancy loss as a percentage of total possible revenue. Total possible revenue (also known as “gross potential”) 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.

Established Communitiesare 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 respective prior year period.  Therefore, for 2015 operating results, Established Communities are consolidated communities that have Stabilized Operations as of January 1, 2014 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. 

FFOis 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 attributable to common stockholders computed in accordance with GAAP, adjusted for gains or losses on sales of previously depreciated operating communities, cumulative effect of a change in accounting principle, impairment write-downs of depreciable real estate assets, write-downs of investments in affiliates which are driven by a decrease in the value of depreciable real estate assets held by the affiliate 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 attributable to common stockholders is as follows (dollars in thousands):

	Q1			Q1
	2015			2014
Net income attributable to common stockholders	$	208,144		$	141,739
Depreciation - real estate assets, including discontinued
operations and joint venture adjustments	118,320			108,966
Distributions to noncontrolling interests, including
discontinued operations	9			9
Gain on sale of unconsolidated entities holding previously
depreciated real estate assets	(9,155		)	—
Gain on sale of previously depreciated real estate assets	(70,936		)	(37,869		)
Impairment due to casualty loss	4,195			—
FFO attributable to common stockholders	$	250,577		$	212,845
Average shares outstanding - diluted	133,175,773			129,629,557
Earnings per share - diluted	$	1.56		$	1.09
FFO per common share - diluted	$	1.88		$	1.64

Initial Year Market Cap Rateis 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 $300 - $500 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 and amortization. For this purpose, management’s projection of operating expenses for the community includes a management fee of 2.5% - 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.

Interest Coverageis calculated by the Company as EBITDA, as adjusted, divided by the sum of interest expense, net, and preferred dividends, if applicable. 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 or loss attributable to the Company before interest income and expense, income taxes, depreciation and amortization. 

A reconciliation of EBITDA, as adjusted, and a calculation of Interest Coverage for the first quarter of 2015 are as follows (dollars in thousands):

Net income attributable to common stockholders	$	208,144
Interest expense, net	45,573
Depreciation expense	116,853
EBITDA	$	370,570
NOI from discontinued operations and real estate assets sold or held for sale, not classified as discontinued operations	836
Gain on sale of communities	70,936
EBITDA after disposition activity	$	298,798
Joint venture income	(34,566		)
EBITDA, as adjusted	$	264,232
Interest expense, net	$	45,573
Interest Coverage	5.8 times

Net Debt-to-Adjusted EBITDAis calculated by the Company as total debt that is consolidated for financial reporting purposes, less consolidated cash and cash in escrow, divided by annualized first quarter 2015 EBITDA, as adjusted.

Total debt principal (1)	$	6,493,278
Cash and cash in escrow	(297,716		)
Net debt	$	6,195,562
Net income attributable to common stockholders	$	208,144
Interest expense, net	45,573
Depreciation expense	116,853
EBITDA	$	370,570
NOI from discontinued operations and real estate assets sold or held for sale, not classified as discontinued operations	836
Gain on sale of communities	70,936
EBITDA after disposition activity	$	298,798
Joint venture income	(34,566		)
EBITDA, as adjusted	$	264,232
EBITDA, as adjusted, annualized	$	1,056,928
Net Debt-to-Adjusted EBITDA	5.9 times
(1) Balance at March 31, 2015 excludes $6,491of debt discount as reflected in unsecured notes, net, and $75,544 of debt premium as reflected in notes payable, on the Condensed Consolidated Balance Sheets. The debt premium is primarily related to above market interest rates on debt assumed in connection with the Archstone acquisition.

NOIis 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 expenses, expensed development and other pursuit costs, net interest expense, gain (loss) on extinguishment of debt, general and administrative expense, joint venture income (loss), depreciation expense, impairment loss on land holdings, gain on sale of real estate assets, gain on sale of discontinued operations, income from discontinued operations and NOI from real estate assets held for sale or that have been sold. 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 to Net Income, as well as a breakdown of NOI by operating segment, is as follows (dollars in thousands):

	Q1			Q1			Q4
	2015			2014			2014
Net income	$	208,053		$	141,599		$	142,530

Non-Revenue Generating Capexrepresents capital expenditures that will not directly result in increased revenue or expense savings.

Other Stabilized Communitiesas of January 1, 2015 are completed consolidated communities that the Company owns, which did not have stabilized operations as of January 1, 2014, but have stabilized occupancy as of January 1, 2015. Other Stabilized Communities as of January 1, 2015 do not include communities that are planning to conduct substantial redevelopment activities or that are under contract to be sold.

Projected FFO and Projected Core FFO, as provided within this release in the Company’s outlook, are calculated on a basis consistent with historical FFO and Core FFO, and are therefore considered to be appropriate supplemental measures to projected Net Income from projected operating performance.  A reconciliation of the ranges provided for Projected FFO per share (diluted) for the second quarter of 2015 to the ranges provided for projected EPS (diluted) and corresponding reconciliation of the ranges for Projected FFO per share to the ranges for Core FFO per share are as follows:

		Low Range			High Range

Projected Core FFO per share (diluted) - Q2 2015		$	1.80		$	1.84

Projected NOI,as used within this release for certain development 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 communities, Projected NOI is calculated based on the first twelve months of Stabilized Operations 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 minus projected stabilized economic vacancy and adjusted for projected stabilized concessions plus projected stabilized other rental revenue.  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. In addition, projected stabilized operating expenses for development communities do not include property management fee expense. Projected gross potential for development communities and dispositions is based on leased rents for occupied homes and management’s best estimate of rental levels for homes which are currently unleased, as well as those homes which will become available for lease during the twelve month forward period used to develop Projected NOI.  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 communities, on an aggregated weighted average basis, assists investors in understanding management's 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 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.

Projected Stabilized Yield(also expressed as “weighted average initial stabilized yield” or words of similar meaning) means Projected NOI as a percentage of Total Capital Cost.

Rental Revenue with Concessions on a Cash Basisis 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):

	Q1			Q1
	2015			2014
Rental revenue (GAAP basis)	$	341,898		$	327,671
Concessions amortized	381			1,569
Concessions granted	(313		)	(1,451		)
Rental Revenue with Concessions
on a Cash Basis	$	341,966		$	327,789
% change -- GAAP revenue				4.3		%
% change -- cash revenue				4.3		%

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

Total Capital Costincludes 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, offset by proceeds from the sale of any associated land or improvements, 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, Total Capital Cost is equal to gross real estate cost.

Unencumbered NOIas 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 quarter ended March 31, 2015 is as follows (dollars in thousands):

	Year To Date
	NOI
NOI for Established Communities	$	237,001
NOI for Other Stabilized Communities	34,008
NOI for Development/Redevelopment Communities	26,988
NOI for discontinued operations	—
NOI from real estate assets sold or held for sale, not classified as discontinued operations	836
Total NOI generated by real estate assets	298,833
NOI on encumbered assets	86,902
NOI on unencumbered assets	$	211,931
Unencumbered NOI	71		%

Unleveraged IRRon 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) is 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 investment period for each respective community, including net sales proceeds.

AVALONBAY COMMUNITIES, INC. ANNOUNCES

FIRST QUARTER 2015 OPERATING RESULTS

(Arlington, VA)  AvalonBay Communities, Inc. (NYSE: AVB) (the “Company”) reported today Net Income Attributable to Common Stockholders for the quarter ended March 31, 2015 of $208,144,000. This resulted in Earnings per Share – diluted (“EPS”) of $1.56 for the three months ended March 31, 2015, compared to $1.09 per share for the comparable period of 2014, an increase of 43.1%.

The increase in EPS for the three months ended March 31, 2015 over the prior year period is due primarily to an increase in real estate sales and related gains, an increase in joint venture income, and an increase in Net Operating Income (“NOI”) from newly developed and existing operating communities.

Funds from Operations attributable to common stockholders - diluted (“FFO”) per share for the three months ended March 31, 2015 increased 14.6% to $1.88 from $1.64 for the comparable period of 2014. FFO per share adjusted for non-routine items as detailed in Attachment 13 ("Core FFO" per share) increased by 7.4% to $1.75 for the three months ended March 31, 2015 over the prior year period.

The following table compares the Company’s actual results for FFO per share and Core FFO per share for the first quarter 2015 to its January 2015 outlook:

First Quarter 2015 Results

(1) Represents the mid-point of the Company's January 2015 outlook.
(2) Includes $0.02 of operating costs related to severe winter storms in the Company's Northeast markets.
(3) Primarily due to the timing of expected settlement proceeds.

Commenting on the Company’s results, Tim Naughton, Chairman and CEO, said, "Our first quarter results reflect sustained strength in apartment fundamentals during the winter months and position us well for the upcoming peak leasing season. Looking ahead, we expect favorable

apartment demand and NOI from development lease-up activity to drive healthy Core FFO growth throughout the balance of the year."

Operating Results for the Quarter Ended March 31, 2015 Compared to the Prior Year Period

For the Company, including discontinued operations, total revenue increased by $41,713,000, or 10.4%, to $442,367,000. This increase is primarily due to growth in revenue from development communities and growth in Established Community revenue noted below. 

For Established Communities, rental revenue increased 4.3% due to an increase in Average Rental Rates. If the Company were to include current and previously completed Redevelopment Communities in its Established Communities portfolio, the increase in Established Communities' rental revenue would have been 4.4%. Total revenue for Established Communities increased $14,392,000 to $342,325,000. Operating expenses for Established Communities increased $2,563,000, or 2.5%, to $105,324,000. The Company’s Established Communities' operating expenses for the three months ended March 31, 2015 include $1,088,000 related to excess and unusual snow removal and other costs from severe winter storms in the Company's Northeast markets. NOI for Established Communities increased $11,829,000, or 5.3%, to $237,001,000.

The following table reflects the percentage changes in rental revenue, operating expenses and NOI for Established Communities for the first quarter of 2015 compared to the first quarter of 2014:

During the three months ended March 31, 2015, the Company engaged in the following development activity:

The Company completed the development of three communities:

• Avalon West Chelsea/AVA High Line, located in New York, NY;

• Avalon Alderwood I, located in Lynnwood, WA; and

• AVA Little Tokyo, located in Los Angeles, CA.

These three communities contain an aggregate of 1,357 apartment homes and were constructed for an aggregate Total Capital Cost of $452,100,000.

The Company started the construction of two communities: Avalon Alderwood II, located in Lynnwood, WA; and Avalon Hunt Valley, located in Hunt Valley, MD. These communities will contain a total of 456 apartment homes when completed and will be developed for an aggregate estimated Total Capital Cost of $100,100,000.

The Company acquired four land parcels for development for an aggregate investment of $361,150,000, which includes the Development Right on the Upper West Side of Manhattan discussed in the Company's February 2, 2015 press release. The Company has started, or anticipates starting, construction of apartment communities on these land parcels during the next 18 months.

The Company added three Development Rights. If developed as expected, these Development Rights will contain a total of 910 apartment homes and will be developed for an aggregate estimated Total Capital Cost of $426,000,000.

The projected Total Capital Cost of overall Development Rights increased to $3.3 billion at March 31, 2015 from $3.2 billion at December 31, 2014.

Disposition Activity

During the three months ended March 31, 2015, the Company sold Avalon on Stamford Harbor, a wholly-owned community located in Stamford, CT. Avalon on Stamford Harbor contains 323 apartment homes and a marina containing 74 boat slips, and was sold for $115,500,000 and an initial year market cap rate of 5.1%, resulting in a gain in accordance with GAAP of $70,936,000 and an Economic Gain of $48,616,000. Avalon on Stamford Harbor yielded an unleveraged IRR of 11.9%over an investment period of14.5years.

Liquidity and Capital Markets

At March 31, 2015, the Company did not have any borrowings outstanding under its $1,300,000,000 unsecured credit facility, and had $297,716,000 in unrestricted cash and cash in escrow.

The Company’s annualized Net Debt-to-Adjusted EBITDA for the first quarter of 2015 was 5.9 times. 

In March 2015, the Company drew the final $50,000,000 available under its $300,000,000 variable rate unsecured term loan (the "Term Loan"), which matures in March 2021.

During September 2014, the Company entered into a forward contract to sell 4,500,000 shares of common stock for an initial forward price of $151.74 per share, net of offering fees and discounts (the "Forward"). The sales price and proceeds achieved by the Company will be determined on the date or dates of settlement, with adjustments during the term of the contract for the Company’s dividends as well as for a daily interest factor that varies with changes in the Fed Funds rate. The Company has not sold any shares of common stock under the Forward. Settlement of the Forward will occur on one or more dates not later than September 8, 2015.

Unconsolidated Real Estate Investments

The Company received $20,680,000 from the joint venture partner associated with MVP I, LLC, the entity that owns Avalon at Mission Bay North II, upon agreement with the partner to modify the joint venture agreement to eliminate the Company's promoted interest for future return calculations and associated distributions. Prospectively, earnings and distributions will be based on the Company's 25.0% equity interest in the venture.

During the three months ended March 31, 2015, AvalonBay Value Added Fund II, L.P. ("Fund II"), a private discretionary real estate investment vehicle in which the Company holds an equity interest of approximately 31.3%, sold one community containing 776 apartment homes for a sales price of $117,000,000. The Company's share of the gain in accordance with GAAP was $9,660,000.

Casualty Losses

In January 2015, a fire occurred at the Company's Avalon at Edgewater apartment community located in Edgewater, New Jersey ("Edgewater"). Edgewater consisted of two residential buildings. One building, which contained 240 apartment homes, suffered a total loss. During the three months ended March 31, 2015, the Company recognized a casualty loss from the write-off of the net book value of the fixed assets destroyed by the fire. The write-off, coupled with additional incident expenses, was substantially offset by third-party insurance proceeds received during the three months ended March 31, 2015, resulting in a net casualty loss of $793,000 for the three months ended March 31, 2015.

During the three months ended March 31, 2015, several of the Company’s communities in its Northeast markets incurred property and casualty damage from severe winter storms, in addition to the incremental operating expenses discussed elsewhere in this release. The Company has recorded a casualty loss of $4,195,000 associated with these damages.

Second Quarter 2015 Financial Outlook

For the second quarter of 2015, the Company expects EPS in the range of $1.03 to $1.07, and expects Projected FFO per share to be in the range of $1.92 to $1.96. Adjusting for non-routine items as detailed in Attachment 13, the Company expects Projected Core FFO per share for the second quarter of 2015 to be in the range of $1.80 to $1.84.

Forward-Looking Statements

This release, including its Attachments, contains forward-looking statements, within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.  These forward-looking statements, which you can identify by the Company’s use of words such as “expects,” “plans,” “estimates,” “anticipates,” “projects,” “intends,” “believes,” “outlook” and similar expressions that do not relate to historical matters, are based on the Company’s expectations, forecasts and assumptions at the time of this release, which may not be realized and involve risks and uncertainties that cannot be predicted accurately or that might not be anticipated. These could cause actual results to differ materially from those expressed or implied by the forward-looking statements. Risks and uncertainties that might cause such differences include the following, among others: the Company's expectations and assumptions as of the date of this release regarding insurance coverage, lender payoff and refinancing requirements, potential uninsured loss amounts and on-going investigations resulting from the Avalon at Edgewater fire, as well as the ultimate cost and timing of replacing the Edgewater building and achieving stabilized occupancy in the event that the Company chooses to rebuild this community, are subject to change and could materially affect the Company's current expectations regarding the impact of the fire and related loss on the Company's financial condition and results of operations; we may abandon development or redevelopment opportunities for which we have already incurred costs; 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; 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; expenses may result in communities that we develop or redevelop failing to achieve expected profitability; our assumptions concerning risks relating to our  lack of control of joint ventures and our abilities to successfully dispose of certain assets may not be realized; our

Copyright © 2015 AvalonBay Communities, Inc. All Rights Reserved

assumptions and expectations in our financial outlook may prove to be too optimistic; the expected proceeds from settlement of the Forward are subject to adjustment for changes in the Fed Funds rate and the amount of dividends we pay on our common stock, and our receipt of settlement proceeds assumes that we will settle the Forward by physical delivery. Additional discussions of risks and uncertainties that could cause actual results to differ materially  from those expressed or implied by the forward-looking statements appear in the Company’s filings with the Securities and Exchange Commission, including the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014 under the heading  “Risk Factors” and under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Forward-Looking Statements” and in subsequent quarterly reports on Form 10-Q.

The Company does not undertake a duty to update forward-looking statements, including its expected 2015 operating results and other financial data forecasts contained in this release. The Company may, in its discretion, provide information in future public announcements regarding its outlook that may be of interest to the investment community.  The format and extent of future outlooks may be different from the format and extent of the information contained in this release.

(1) See Attachment #13 - Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms.

(2) Property taxes increased for the three months ended March 31, 2015 primarily due to increases in rates and assessments, particularly in the Company's East Coast and Pacific Northwest markets, partially offset by reductions and a successful appeal of a California community in the three months ended March 31, 2015.

(3) Payroll includes expenses directly related to on-site operations and increased for the three months ended March 31, 2015 due to increases in benefits costs from higher medical claims and compliance with the provisions of the Affordable Care Act.

(4) Repairs and maintenance increased for the three months ended March 31, 2015 primarily due to snow removal and other costs related to severe winter storms in the Company's Northeast markets.

(5) Office operations includes administrative costs, land lease expense, bad debt expense and association and license fees. The decrease for the three months ended March 31, 2015 from the prior year period is primarily due to a decrease in bad debt expense and the timing of accounting and auditing fees, partially offset by an increase in state income taxes.

(6) Utilities represent aggregate utility costs, net of resident reimbursements. The decrease for the three months ended March 31, 2015 from the prior year period is primarily due to a decrease in electricity consumption and electric rates, as well as a decrease in gas consumption, partially offset by an increase in water and sewer expenses, net of resident reimbursements.

(7) Insurance costs consist of premiums, expected claims activity and associated reductions from receipt of claims recoveries. The increase for the three months ended March 31, 2015 over the prior year period is primarily due to the timing of claims and related recoveries. Insurance costs can exhibit volatility due to the amounts and timing of estimated and actual claim activity and the related recoveries received.

(8) Marketing costs represent amounts incurred for electronic and print advertising, as well as prospect management and incentive costs. The increase for the three months ended March 31, 2015 over the prior year period is primarily due increased customer service incentives related to the severe winter storms in the Company's Northeast markets, partially offset by decreased internet advertising costs.

(9) Operating expenses for Established Communities excludes indirect costs for off-site corporate-level property management related expenses and other support-related expenses.

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.

Average Post-Renovated Rent per Homefor Redevelopment Communities reflects management’s projected stabilized rents net of stabilized concessions and including stabilized other rental revenue once all homes have been renovated and subsequently re-leased.

Average Rent per Home,as calculated for certain Development and Redevelopment Communities in lease-up,  reflects management’s projected stabilized rents net of estimated stabilized concessions, including estimated stabilized other rental revenue and excluding projected commercial revenue.  Projected stabilized rents are based on one or more of the following:  (i) actual average leased rents on apartments leased through quarter end; (ii) projected rollover rents on apartments leased through quarter end where the lease term expires within the first twelve months of Stabilized Operations, and (iii) Market Rents on unleased homes.

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

Debt Covenant Compliance ratios for the Unsecured Line of Credit Covenants show the Company's compliance with selected covenants provided in the Company’s Third Amended and Restated Revolving Loan Agreement dated as of September 29, 2011, as amended by Amendment No. 1 dated as of December 20, 2012, and the Company’s Term Loan Agreement dated March 31, 2014, which have been filed as exhibits to the Company’s periodic reports with the SEC. The ratios for the Unsecured Senior Notes Covenants show the Company's compliance with selected covenants provided in the Company’s Indenture dated as of January 16, 1998, as supplemented by the First Supplemental Indenture dated as of January 20, 1998, Second Supplemental Indenture dated as of July 7, 1998, Amended and Restated Third Supplemental Indenture dated as of July 20, 2000, Fourth Supplemental Indenture dated as of September 18, 2006 and Fifth Supplemental Indenture dated as of November 21, 2014, which have been filed as exhibits to the Company’s periodic reports with the SEC.

The Debt Covenant Compliance ratios are provided only to show the Company’s compliance with certain covenants contained in the Indenture governing its unsecured debt securities and in the Company’s Credit Facility and Term Loan, as of the date reported. These ratios should not be used for any other purpose, including without limitation to evaluate the Company’s financial condition or results of operations, nor do they indicate the Company’s covenant compliance as of any other date or for any other period. The capitalized terms in the disclosure are defined in the Indenture or the Credit Facility and may differ materially from similar terms (a) used elsewhere in this release and the Attachments and (b) used by other companies that present information about their covenant compliance. For risks related to failure to comply with these covenants, see “Risk Factors – Risks related to indebtedness” and other risks discussed in the Company’s Annual Report on Form 10-K and the Company’s other reports filed with the SEC.

Debt-to-Total Market Capitalizationis a measure of leverage that is calculated by expressing, as a percentage, debt divided by Total Market Capitalization, which is defined as 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) and the outstanding principal balance of debt.  Management believes that this measure of 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. Because this measure of leverage changes with fluctuations in the Company’s stock price, which occur regularly, this measure 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.

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

Development Rightsare 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, where the Company controls the land through a ground lease or owns land to develop a new community, or where the Company is the designated developer in a public-private partnership. The Company capitalizes related pre-development costs incurred in pursuit of new developments for which future development is probable.

Economic Gain (Loss)is calculated by the Company as the gain (loss) 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 (Loss) to be an appropriate supplemental measure to gain (loss) 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 (Loss) for each of the communities presented is estimated based on their respective final settlement statements.  A reconciliation of Economic Gain (Loss) to gain on sale in accordance with GAAP for the quarter ended March 31, 2015 as well as prior years’ activities is presented elsewhere on Attachment 12.

Economic Occupancy (“Ec Occ”)is defined as total possible revenue less vacancy loss as a percentage of total possible revenue. Total possible revenue (also known as “gross potential”) 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.

Established Communitiesare 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 respective prior year period.  Therefore, for 2015 operating results, Established Communities are consolidated communities that have Stabilized Operations as of January 1, 2014 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. 

Attachment 13

FFOis 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 attributable to common stockholders computed in accordance with GAAP, adjusted for gains or losses on sales of previously depreciated operating communities, cumulative effect of a change in accounting principle, impairment write-downs of depreciable real estate assets, write-downs of investments in affiliates which are driven by a decrease in the value of depreciable real estate assets held by the affiliate 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 attributable to common stockholders is as follows (dollars in thousands):

	Q1			Q1
	2015			2014
Net income attributable to common stockholders	$	208,144		$	141,739
Depreciation - real estate assets, including discontinued
operations and joint venture adjustments	118,320			108,966

Earnings per share - diluted	$	1.56		$	1.09
FFO per common share - diluted	$	1.88		$	1.64

Initial Year Market Cap Rateis 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 $300 - $500 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 and amortization. For this purpose, management’s projection of operating expenses for the community includes a management fee of 2.5% - 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.

Interest Coverageis calculated by the Company as EBITDA, as adjusted, divided by the sum of interest expense, net, and preferred dividends, if applicable. 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 or loss attributable to the Company before interest income and expense, income taxes, depreciation and amortization. 

Attachment 13

A reconciliation of EBITDA, as adjusted, and a calculation of Interest Coverage for the first quarter of 2015 are as follows (dollars in thousands):

Net income attributable to common stockholders	$	208,144
Interest expense, net	45,573
Depreciation expense	116,853
EBITDA	$	370,570
NOI from discontinued operations and real estate assets sold or held for sale, not classified as discontinued operations	836
Gain on sale of communities	70,936
EBITDA after disposition activity	$	298,798
Joint venture income	(34,566		)
EBITDA, as adjusted	$	264,232
Interest expense, net	$	45,573
Interest Coverage	5.8 times

Market Rentsas reported by the Company are based on the current market rates set by the managers of the Company’s 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.

Net Debt-to-Adjusted EBITDAis calculated by the Company as total debt that is consolidated for financial reporting purposes, less consolidated cash and cash in escrow, divided by annualized first quarter 2015 EBITDA, as adjusted.

Total debt principal (1)	$	6,493,278
Cash and cash in escrow	(297,716		)
Net debt	$	6,195,562
Net income attributable to common stockholders	$	208,144

(1) Balance at March 31, 2015 excludes $6,491of debt discount as reflected in unsecured notes, net, and $75,544 of debt premium as reflected in notes payable, on the Condensed Consolidated Balance Sheets. The debt premium is primarily related to above market interest rates on debt assumed in connection with the Archstone acquisition.

Attachment 13

NOIis 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 expenses, expensed development and other pursuit costs, net interest expense, gain (loss) on extinguishment of debt, general and administrative expense, joint venture income (loss), depreciation expense, impairment loss on land holdings, gain on sale of real estate assets, gain on sale of discontinued operations, income from discontinued operations and NOI from real estate assets held for sale or that have been sold. 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 to Net Income, as well as a breakdown of NOI by operating segment, is as follows (dollars in thousands):

	Q1			Q1			Q4

NOI as reported by the Company does not include the operating results from discontinued operations (i.e., assets sold or classified as held for sale at December 31, 2013) or assets sold or classified as held for sale (i.e., assets sold or classified as held for sale at March 31, 2015 that are not otherwise classified as discontinued operations).  A reconciliation of NOI from communities sold, classified as discontinued operations or classified as held for sale, to Net Income for these communities is as follows (dollars in thousands):

Non-Revenue Generating Capexrepresents capital expenditures that will not directly result in increased revenue or expense savings.

Other Stabilized Communitiesas of January 1, 2015 are completed consolidated communities that the Company owns, which did not have stabilized operations as of January 1, 2014, but have stabilized occupancy as of January 1, 2015. Other Stabilized Communities as of January 1, 2015 do not include communities that are planning to conduct substantial redevelopment activities or that are under contract to be sold.

Projected FFO and Projected Core FFO, as provided within this release in the Company’s outlook, are calculated on a basis consistent with historical FFO and Core FFO, and are therefore considered to be appropriate supplemental measures to projected Net Income from projected operating performance.  A reconciliation of the ranges provided for Projected FFO per share (diluted) for the second quarter of 2015 to the ranges provided for projected EPS (diluted) and corresponding reconciliation of the ranges for Projected FFO per share to the ranges for Core FFO per share are as follows:

		Low Range			High Range
Projected EPS (diluted) - Q2 2015		$	1.03		$	1.07
	Projected depreciation (real estate related)	0.89			0.93
	Projected gain on sale of operating communities	—			(0.04		)
Projected FFO per share (diluted) - Q2 2015		1.92			1.96

Projected Core FFO per share (diluted) - Q2 2015		$	1.80		$	1.84

Attachment 13

Projected NOI,as used within this release for certain Development 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 Communities, Projected NOI is calculated based on the first twelve months of Stabilized Operations 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 minus projected stabilized economic vacancy and adjusted for projected stabilized concessions plus projected stabilized other rental revenue.  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. In addition, projected stabilized operating expenses for Development Communities do not include property management fee expense. Projected gross potential for Development Communities and dispositions is based on leased rents for occupied homes and management’s best estimate of rental levels for homes which are currently unleased, as well as those homes which will become available for lease during the twelve month forward period used to develop Projected NOI.  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 Communities, on an aggregated weighted average basis, assists investors in understanding management's 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 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.

Projected Stabilized Yield(also expressed as “weighted average initial stabilized yield” or words of similar meaning) means Projected NOI as a percentage of Total Capital Cost.

Redevelopment Communitiesare 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 generally considered substantial when capital invested during the reconstruction effort is expected to exceed either $5,000,000 or 10% of the community’s pre-redevelopment basis and is expected to have a material impact on the community’s operations, including occupancy levels and future rental rates.

Rental Revenue with Concessions on a Cash Basisis 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):

	Q1			Q1
	2015			2014
Rental revenue (GAAP basis)	$	341,898		$	327,671
Concessions amortized	381			1,569
Concessions granted	(313		)	(1,451		)
Rental Revenue with Concessions
on a Cash Basis	$	341,966		$	327,789
% change -- GAAP revenue				4.3		%
% change -- cash revenue				4.3		%

Attachment 13

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

Total Capital Costincludes 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, offset by proceeds from the sale of any associated land or improvements, 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, Total Capital Cost is equal to gross real estate cost.

Unencumbered NOIas 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 quarter ended March 31, 2015 is as follows (dollars in thousands):

	Year To Date
	NOI
NOI for Established Communities	$	237,001
NOI for Other Stabilized Communities	34,008
NOI for Development/Redevelopment Communities	26,988
NOI for discontinued operations	—
NOI from real estate assets sold or held for sale, not classified as discontinued operations	836
Total NOI generated by real estate assets	298,833
NOI on encumbered assets	86,902
NOI on unencumbered assets	$	211,931
Unencumbered NOI	71		%

Unleveraged IRRon 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) is 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 investment period for each respective community, including net sales proceeds.
