AVALONBAY COMMUNITIES, INC. ANNOUNCES

THIRD QUARTER 2017 OPERATING RESULTS

(Arlington, VA) AvalonBay Communities, Inc. (NYSE: AVB) (the “Company”) reported today that Net Income Attributable to Common Stockholders for the three months ended September 30, 2017 was $238,248,000. This resulted in a decrease in Earnings per Share – diluted (“EPS”) of 33.6% to $1.72 for the three months ended September 30, 2017, from $2.59 for the prior year period.

Funds from Operations attributable to common stockholders - diluted (“FFO”) per share for the three months ended September 30, 2017 increased 10.9% to $2.34 from $2.11 for the prior year period.

Core FFO per share (as defined in this release) for the three months ended September 30, 2017 increased 5.8% to $2.19 from $2.07 for the prior year period.

The changes in the Company's EPS, FFO per share and Core FFO per share reflect an increase in Net Operating Income (“NOI”) from existing, acquired and newly developed operating communities for the three months ended September 30, 2017 over the prior year period. The changes in EPS and FFO per share were impacted by the increase in joint venture promoted interest in the current year period. The decrease in EPS was also due to a decrease in gains on sale of real estate and an increase in depreciation.

The following table compares the Company’s actual results for EPS, FFO per share and Core FFO per share for the third quarter of 2017 to its August 2017 outlook:

(1)	Operating expenses for Established Communities excludes indirect costs for off-site corporate-level property management related expenses and other support-related expenses. See Attachment 13 - Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms.


(2)	Property taxes increased for the three and nine months ended September 30, 2017 over the prior year periods primarily due to increases in assessments in the current year periods, as well as successful appeals in the prior year periods in the Company's West Coast markets.


(3)	Payroll increased for the three and nine months ended September 30, 2017 over the prior year periods primarily due to increased on-site payroll costs, including benefits costs and compensation attributable to hiring associates for positions that were outsourced in the prior year periods.


(4)	Repairs and maintenance decreased for the three months ended September 30, 2017 from the prior year period primarily due to decreased turnover costs and the timing of various maintenance projects. The increase for the nine months ended September 30, 2017 over the prior year period is primarily due to increased uninsured repair costs, common area maintenance costs and turnover costs.

(5)

Office operations includes administrative costs, land lease expense, bad debt expense and association and license fees. The increase for the three months ended September 30, 2017 over the prior year period is primarily due to retail bad debt expense, as well as an increase in association fees. The increase for the nine months ended September 30, 2017 over the prior year period is primarily due to an increase in retail and residential bad debt expense, government license and association fees, and land lease expense. This was partially offset by a decrease in temporary help costs due to transitioning outsourced positions to full and part time associates, which partially offsets the increase in payroll.

(6)

Utilities represents aggregate utility costs, net of resident reimbursements. The decrease for the three months ended September 30, 2017 from the prior year period is primarily due to a decrease in electrical consumption and decreased water and sewer expense, net of resident reimbursements, partially offset by increased trash removal costs. The increase for the nine months ended September 30, 2017 over the prior year period is primarily due to increased gas expense, due to higher rates and consumption, and increased trash removal costs, partially offset by a decrease in electrical consumption and decreased water and sewer expense, 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 September 30, 2017 over the prior year period is primarily due to increased property insurance premiums and deductibles, partially offset by the timing of claims and related recoveries. The decrease for the nine months ended September 30, 2017 from the prior year period is primarily due to decreased property insurance premiums and the timing of claims and related recoveries, partially offset by increased property insurance deductibles. Insurance costs can be variable due to the amounts and timing of estimated and actual claim activity and the related recoveries received.

Definitions and Reconciliations of Non-GAAP Financial Measures and Other Terms

September 30, 2017

(unaudited)

This release, including its attachments, contains certain non-GAAP financial measures and other terms. The definitions and calculations 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 Rent per Home, as calculated for certain Development 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 Rates are 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 Fourth Amended and Restated Revolving Loan Agreement dated as of January 14, 2016, the Company’s Term Loan Agreement dated March 31, 2014 and the Company’s Term Loan Agreement dated February 28, 2017, which have been filed as exhibits to the Company’s SEC reports. 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 SEC reports.

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 Loans, 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 the Term Loans, 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.

Development Communities are communities that are under construction and for which a certificate or certificates of occupancy for the entire community has not been received. These communities may be partially complete and operating.

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, 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 the Company currently believes future development is probable.

Attachment 13

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 based on their respective final settlement statements. A reconciliation of Economic Gain (Loss) to gain on sale in accordance with GAAP for the nine months ended September 30, 2017 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 Communities are consolidated 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 2017 operating results, Established Communities are consolidated communities that have Stabilized Operations as of January 1, 2016, are not conducting or planning to conduct substantial redevelopment activities and are not held for sale or planned for disposition within the current year.

FFO and Core FFO are considered by management to be supplemental measures of our operating and financial performance. FFO is calculated by the Company in accordance with the 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. 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 and financial performance of a company’s real estate between periods or as compared to different companies. Core FFO is the Company's FFO as adjusted for non-core items outlined in the table below. By further adjusting for items that are not considered part of our core business operations, Core FFO can help one compare the core operating and financial performance of the Company between periods. A reconciliation of Net income attributable to common stockholders to FFO and to Core FFO is as follows (dollars in thousands):

(1) In YTD 2016, the Company received insurance proceeds, net of additional costs incurred, of $5,732 related to the severe winter storms that occurred in the Company’s Northeast markets in 2015. For YTD 2016, the Company recognized $4,195 of this recovery as an offset to the impairment on depreciable real estate of $4,195 recognized in the prior year period. The balance of the net insurance proceeds received in 2016 of $1,537 is recognized as a casualty gain and is included in the reconciliation of FFO to Core FFO.
(2) Amounts for 2016 and 2017 are primarily composed of (i) the Company's portion of yield maintenance charges incurred for the early repayment of debt associated with joint venture disposition activity, (ii) the write-off of asset management fee intangibles primarily associated with the disposition of communities in the U.S. Fund and (iii) the Company's proportionate share of operating results for joint ventures formed with Equity Residential as part of the Archstone acquisition.
(3) Amounts for 2017 and 2016 are composed of the Company's recognition of its promoted interest in Fund II.
(4) Amount for YTD 2017 includes an impairment charge for a land parcel the Company had acquired for development and sold in July 2017. Amount for YTD 2016 includes impairment charges relating to ancillary land parcels.
(5) Amount for YTD 2017 includes $19,481 for the Maplewood casualty loss, partially offset by $17,143 of expected property damage insurance proceeds, a portion of which were received during the period. Amount for YTD 2016 includes $8,702 in property damage insurance proceeds for the Edgewater casualty loss, and $1,537 in insurance proceeds in excess of the total recognized loss related to severe winter storms in the Company's Northeast markets that occurred in 2015.
(6) Aggregate impact of (i) Casualty and impairment (recovery) loss, net on real estate, (ii) Impairment loss on real estate and (iii) Casualty loss (gain), net on real estate, is a loss of $11,688 for YTD 2017, and a gain of $3,935 for YTD 2016, respectively, as shown on Attachment 1 - Detailed Operating Information.
(7) Amounts for 2017 are composed of business interruption insurance proceeds resulting from the final insurance settlement of the Maplewood casualty loss. Amount for YTD 2016 is primarily composed of business interruption insurance proceeds resulting from the final insurance settlement of the Edgewater casualty loss.
(8) Amounts for 2016 and 2017 primarily relate to a casualty event at Edgewater in Q1 2015, for which the Company received $20,306 in business interruption insurance proceeds in Q1 2016. Amounts for 2017 also include amounts related to the Maplewood casualty loss in Q1 2017, for which the Company recognized $3,495 in business interruption insurance proceeds in Q3 2017.

Attachment 13

Gross Levered IRR is calculated as the internal rate of return on the Company's equity investment in Fund II considering the timing and amounts of capital contributions and distributions, including promoted interest earned on the Company’s general partnership interest.

Gross Levered Cash Flow Multiple is calculated as the ratio of the Company’s share of distributions from Fund II, including promoted interest earned, to the Company’s share of contributions in Fund II.

The calculation of Gross Levered IRR and Gross Levered Cash Flow Multiple excludes all management fees earned by the Company during the investment period.

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 $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 Coverage is calculated by the Company as Core EBITDA 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 Core EBITDA and a calculation of Interest Coverage for the three months ended September 30, 2017 are as follows (dollars in thousands):





Net income attributable to common stockholders	$	238,248
Interest expense, net, inclusive of loss on extinguishment of debt, net	47,741
Income tax expense	24
Depreciation expense	144,990
EBITDA	$	431,003

NOI from real estate assets sold or held for sale	(1,874		)
Gain on sale of communities	(27,738		)
Loss on sale of other real estate	120
Joint venture income	(52,568		)
Consolidated EBITDA after disposition activity	$	348,943

Lost NOI from casualty losses covered by business interruption insurance	2,375
Business interruption insurance proceeds	(3,495		)
Severance related costs	18
Development pursuit and other write-offs	339
Legal settlements	7
Core EBITDA	$	348,187

Interest expense, net	$	47,741

Interest Coverage	7.3 times

Attachment 13

Market Rents as 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-Core EBITDA is calculated by the Company as total debt that is consolidated for financial reporting purposes, less consolidated cash and cash in escrow, divided by annualized third quarter 2017 Core EBITDA, as adjusted. For a calculation of Core EBITDA, see "Interest Coverage" above. A calculation of Net Debt-to-Core EBITDA is as follows (dollars in thousands):





Total debt principal (1)	$	7,198,443
Cash and cash in escrow	(217,111		)
Net debt	$	6,981,332

Core EBITDA	$	348,187

Core EBITDA, annualized	$	1,392,748

Net Debt-to-Core EBITDA	5.0 times

(1) Balance at September 30, 2017 excludes $9,392 of debt discount and $33,517 of deferred financing costs as reflected in unsecured notes, net, and $16,280 of debt discount and $11,224 of deferred financing costs as reflected in notes payable, on the Condensed Consolidated Balance Sheets.

NOI is defined by the Company as total property revenue less direct property operating expenses (including property taxes), and excluding corporate-level income (including management, development and other fees), corporate-level property management and other indirect operating expenses, investments and investment management expenses, expensed acquisition, development and other pursuit costs, net of recoveries, interest expense, net, loss (gain) on extinguishment of debt, net, general and administrative expense, joint venture income, depreciation expense, corporate income tax expense, casualty and impairment (gain) loss, net, gain on sale of real estate and net operating income from real estate assets sold or held for sale. The Company considers NOI to be an important and appropriate supplemental performance 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 any corporate-level property management overhead or financing-related costs. NOI reflects the operating performance of a community, and allows for an easier comparison of the operating performance of individual assets or groups of assets. In addition, because prospective buyers of real estate have different financing and overhead structures, with varying marginal impact to overhead as a result of 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):

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

Other Stabilized Communities are completed consolidated communities that the Company owns, which have Stabilized Operations as of January 1, 2017. Other Stabilized Communities do not include communities that are conducting or planning to conduct substantial redevelopment activities.

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 fourth quarter and full year 2017 to the ranges provided for projected EPS (diluted) and corresponding reconciliation of the ranges for Projected FFO per share to the ranges for Projected Core FFO per share are as follows:

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.

Attachment 13

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 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 Communities are consolidated communities 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 the lesser of $5,000,000 or 10% of the community’s pre-redevelopment basis and is expected to have a material impact on the operations of the community, including occupancy levels and future rental rates.

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):




	Q3			Q3			YTD			YTD
	2017			2016			2017			2016
Rental revenue (GAAP basis)	$	398,136		$	389,474		$	1,180,074		$	1,149,866
Concessions amortized	422			472			1,365			1,979
Concessions granted	(220		)	(508		)	(787		)	(1,086		)

Rental Revenue with Concessions
on a Cash Basis	$	398,338		$	389,438		$	1,180,652		$	1,150,759

Revenue Generating Capex represents capital expenditures that the Company expects will directly result in increased revenue or expense savings, and excludes any capital expenditures for Redevelopment Communities.

Stabilized Operations/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.

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, 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.

Attachment 13

Unencumbered NOI as calculated by the Company represents NOI generated by real estate assets unencumbered by outstanding secured debt as of September 30, 2017 as a percentage of total NOI generated by real estate assets. The Company believes that current and prospective unsecured creditors of the Company view Unencumbered NOI as one indication of the borrowing capacity of the Company. Therefore, when reviewed together with the Company’s Interest Coverage, EBITDA and cash flow from operations, the Company believes that investors and creditors view Unencumbered NOI as a useful supplemental measure for determining the financial flexibility of an entity. A calculation of Unencumbered NOI for the nine months ended September 30, 2017 is as follows (dollars in thousands):




	Year to Date
	NOI
NOI for Established Communities	$	831,400
NOI for Other Stabilized Communities	146,242
NOI for Development/Redevelopment Communities	125,297
NOI from real estate assets sold or held for sale	9,633
Total NOI generated by real estate assets	1,112,572
NOI on encumbered assets	125,833
NOI on unencumbered assets	$	986,739

Unencumbered NOI	89		%

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) 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.
