PART I

        This Form 10-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Our actual results could differ materially from those set forth in each forward-looking statement. Certain factors that might cause such a difference are discussed in this report, including in the section entitled "Forward-Looking Statements" included in this Form 10-K. You should also review Item 1a., "Risk Factors," for a discussion of various risks that could adversely affect us.

ITEM 1.    BUSINESS

General

        AvalonBay Communities, Inc. (the "Company," which term, unless the context otherwise requires, refers to AvalonBay Communities, Inc. together with its subsidiaries) is a Maryland corporation that has elected to be treated as a real estate investment trust ("REIT") for federal income tax purposes. We engage in the development, redevelopment, acquisition, ownership and operation of multifamily communities in high barrier to entry markets of the United States. These barriers to entry generally include a difficult and lengthy entitlement process with local jurisdictions and dense urban or suburban areas where zoned and entitled land is in limited supply. Our markets are currently located in the following regions of the United States: New England, the New York/New Jersey Metro area, the Mid-Atlantic, the Pacific Northwest, and Northern and Southern California. We focus on these markets because we believe that, over the long-term, a limited new supply of apartment homes and lower housing affordability in these markets will result in higher growth in cash flows relative to other markets.

        At January 31, 2013, we owned or held a direct or indirect ownership interest in:

    •
    178 operating apartment communities containing 52,427 apartment homes in nine states and the District of Columbia, of which 155 communities containing 45,056 apartment homes were consolidated for financial reporting purposes, two communities containing 674 apartment homes were held by joint ventures in which we hold an ownership interest, and 21 communities containing 6,697 apartment homes were owned by the Funds (as defined below). Five of the consolidated communities containing 1,787 apartment homes were under redevelopment, as discussed below;

    •
    23 wholly-owned communities under construction that are expected to contain an aggregate of 6,599 apartment homes when completed; and

    •
    rights to develop an additional 34 communities that, if developed in the manner expected, will contain an estimated 9,602 apartment homes.

        The Company has entered into a material agreement to purchase direct and indirect interests in real estate assets that will significantly change our property holdings and capital structure. See "Business—Archstone Acquisition." The closing of the acquisition is expected to occur during the first quarter of 2013 after the filing of this Form 10-K.

        We generally obtain ownership in an apartment community by developing a new community on vacant land or by acquiring an existing community. In selecting sites for development or acquisition, we favor locations that are near expanding employment centers and convenient to transportation, recreation areas, entertainment, shopping and dining.

        Our consolidated real estate investments consist of the following reportable segments: Established Communities, Other Stabilized Communities and Development/Redevelopment Communities. Established Communities are generally operating communities that were owned and had stabilized occupancy and operating expenses as of the beginning of the prior year such that year-over-year

1


Table of Contents

comparisons are meaningful. Other Stabilized Communities are generally all other operating communities that have stabilized occupancy and operating expenses during the current year, but that were not owned or had not achieved stabilization as of the beginning of the prior year such that year-over-year comparisons are not meaningful, as well as communities that are planned for disposition during the current year. Development/Redevelopment Communities consist of communities that are under construction, communities where substantial redevelopment is in progress or is planned to begin during the current year and communities under lease-up. A more detailed description of these segments and other related information can be found in Note 8, "Segment Reporting," of the Consolidated Financial Statements set forth in Item 8 of this report.

        Our principal financial goal is to increase long-term stockholder value through the development, redevelopment, acquisition, operation, and when appropriate, disposition of apartments in our markets. To help meet this goal, we regularly (i) monitor our investment allocation by geographic market and product type, (ii) develop, redevelop and acquire an interest in apartment communities in high barrier to entry markets with growing or high potential for demand and high for-sale housing costs, (iii) selectively sell apartment communities that no longer meet our long-term strategy or when opportunities are presented to realize a portion of the value created through our investment and redeploy the proceeds from those sales and (iv) endeavor to maintain a capital structure that is aligned with our business risks with a view to maintaining continuous access to cost-effective capital. Our strategy is to be leaders in multifamily market research, consumer insight and capital allocation, delivering a range of multifamily offerings tailored to serve the needs of the most attractive customer segments in the best-performing U.S. submarkets. A substantial majority of our current communities are upscale, which generally command among the highest rents in their markets. However, we also pursue the ownership and operation of apartment communities that target a variety of customer segments and price points, consistent with our goal of offering a broad range of products and services.

        We operate our apartment communities under three core brands Avalon, AVA, and Eaves by Avalon. We believe that this branding differentiation allows us to target our product offerings to multiple customer groups and submarkets within our existing geographic footprint. The "Avalon" brand is our core offering, focusing on upscale apartment living and high end amenities and services in urban and suburban markets. Our "AVA" brand is designed for people who want to live in or near urban neighborhoods and in close proximity to public transportation, services, shopping and night-life. AVA apartments are generally smaller, many engineered for roommate living, and feature modern design and a technology focus. Our Eaves by Avalon brand is designed for renters who seek good quality apartment living, often in a suburban setting, with practical amenities and services at a more modest price point.

        During the three years ended December 31, 2012, excluding activity for the Funds (as defined below), we acquired four apartment communities. In addition, during this period we purchased our joint venture partner's interest in one operating community, obtaining a 100% ownership interest in that apartment community. During the same three-year period, excluding dispositions in which we retained an ownership interest, we disposed of 10 apartment communities and completed the development of 18 apartment communities and the redevelopment of 23 apartment communities. In addition, in 2011 we exchanged a portfolio of three communities and a parcel of land we owned for a portfolio of six communities and $26,000,000 in cash.

        During this period, we also realized our pro rata share of the gain from the sale of eight communities owned by AvalonBay Value Added Fund, L.P. ("Fund I"), an institutional discretionary real estate investment fund which we manage and in which we own a 15.2% interest. Fund I acquired communities with the objective of either redeveloping or repositioning them, or taking advantage of market cycle timing and improved operating performance. From its inception in March 2005 through the close of its investment period in March 2008, Fund I acquired 20 communities. In addition, Fund I sold one community in 2013 through the date this Form 10-K was filed.

Table of Contents

        In September 2008 we formed AvalonBay Value Added Fund II, L.P. ("Fund II"), a second institutional discretionary real estate investment fund which we manage and in which we own a 31.3% interest. In 2012, Fund II acquired its final operating community, which was an active acquisition candidate as of August 2011, the end of the investment period for Fund II. From the commencement of Fund II through the close of the investment period, Fund II acquired 13 operating communities. Fund II sold one community in 2013 through the date this Form 10-K was filed. A more detailed description of Fund I and Fund II (collectively, the "Funds") and the related investment activity can be found in the discussion in Note 6, "Investments in Real Estate Entities," of the Consolidated Financial Statements in Item 8 of this report and in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations."

        Including sales by unconsolidated entities and entities in which we held a residual profits interest, during 2012 we sold 12 real estate assets, consisting of 11 operating communities and one land parcel, and recognized a gain in accordance with U.S. generally accepted accounting principles ("GAAP") of $156,420,000.

        A further discussion of our development, redevelopment, disposition, acquisition, property management and related strategies follows.

        Development Strategy.    We select land for development and follow established procedures that we believe minimize both the cost and the risks of development. As one of the largest developers of multifamily rental apartment communities in high barrier to entry markets of the United States, we identify development opportunities through local market presence and access to local market information achieved through our regional offices. In addition to our principal executive office in Arlington, Virginia, we also maintain regional offices, administrative offices or specialty offices in or near the following cities:

    •
    Boston, Massachusetts;

    •
    Long Island, New York;

    •
    Los Angeles, California;

    •
    New York, New York;

    •
    Newport Beach, California;

    •
    San Francisco, California;

    •
    San Jose, California;

    •
    Seattle, Washington;

    •
    Shelton, Connecticut;

    •
    Virginia Beach, Virginia; and

    •
    Woodbridge, New Jersey.

        After selecting a target site, we usually negotiate for the right to acquire the site either through an option or a long-term conditional contract. Options and long-term conditional contracts generally allow us to acquire the target site shortly before the start of construction, which reduces development-related risks and preserves capital. However, as a result of competitive market conditions for land suitable for development, we have sometimes acquired and held land prior to construction for extended periods while entitlements are obtained, or acquired land zoned for uses other than residential with the potential for rezoning. For further discussion of our Development Rights, refer to Item 2. "Communities" in this report.

Table of Contents

        We generally act as our own general contractor and construction manager, except for certain mid-rise and high-rise apartment communities where we may elect to use third-party general contractors as construction managers. We generally perform these functions directly (although we may use a wholly-owned subsidiary) both for ourselves and for the joint ventures and partnerships of which we are a member or a partner. We believe direct involvement in construction enables us to achieve higher construction quality, greater control over construction schedules and cost savings. Our development, property management and construction teams monitor construction progress to ensure quality workmanship and a smooth and timely transition into the leasing and operating phase.

        During periods where competition for development land is more intense, we may acquire improved land with existing commercial uses and rezone the site for multifamily residential use. During the period that we hold these buildings for future development, any rent received from these operations, which we consider to be incidental, is accounted for as a reduction in our investment in the development pursuit and not as net income. We have also participated, and may in the future participate, in master planned or other large multi-use developments where we commit to build infrastructure (such as roads) to be used by other participants or commit to act as construction manager or general contractor in building structures or spaces for third parties (such as unimproved ground floor retail space, municipal garages or parks). Costs we incur in connection with these activities may be accounted for as additional invested capital in the community or we may earn fee income for providing these services. Particularly with large scale, urban in-fill developments, we may engage in significant environmental remediation efforts to prepare a site for construction.

        Throughout this report, the term "development" is used to refer to the entire property development cycle, including pursuit of zoning approvals, procurement of architectural and engineering designs and the construction process. References to "construction" refer to the actual construction of the property, which is only one element of the development cycle.

        Redevelopment Strategy.    When we undertake the redevelopment of a community, our goal is to renovate and/or rebuild an existing community so that our total investment is generally below replacement cost and the community is well positioned in the market to achieve attractive returns on our capital. We have a dedicated group of associates and procedures that are intended to control both the cost and risks of redevelopment. Our redevelopment teams, which include redevelopment, construction and property management personnel, monitor redevelopment progress. We believe we achieve significant cost savings by acting as our own general contractor. More importantly, this helps to ensure quality design and workmanship and a smooth and timely transition into the lease-up and restabilization phases.

        Throughout this report, the term "redevelopment" is used to refer to the entire redevelopment cycle, including planning and procurement of architectural and engineering designs, budgeting and actual renovation work. The actual renovation work is referred to as "reconstruction," which is only one element of the redevelopment cycle.

        Disposition Strategy.    We sell assets that no longer meet our long-term strategy or when market conditions are favorable, and we redeploy the proceeds from those sales to develop, redevelop and acquire communities and to rebalance our portfolio across or within geographic regions. This also allows us to realize a portion of the value created through our investments and provides additional liquidity. We are then able to redeploy the net proceeds from our dispositions in lieu of raising that amount of capital externally. When we decide to sell a community, we generally solicit competing bids from unrelated parties for these individual assets and consider the sales price of each proposal.

        Acquisition Strategy.    Our core competencies in development and redevelopment discussed above allow us to be selective in the acquisitions we target. Acquisitions allow us to achieve rapid penetration into markets in which we desire an increased presence. Acquisitions (and dispositions) also help us

4


Table of Contents

achieve our desired product mix or rebalance our portfolio. Portfolio growth also allows for fixed general and administrative costs to be a smaller percentage of overall community Net Operating Income ("NOI"). We are not presently pursuing the formation of a new, third fund, preferring at this time to maintain flexibility in shaping our portfolio of wholly-owned assets through acquisitions and disposition, although we may acquire investments in existing fund structures in connection with the Archstone Acquisition. Any fund acquired is not expected to limit our ability to acquire investments for our own account.

        Property Management Strategy.    We seek to increase operating income through innovative, proactive property management that will result in higher revenue from communities while constraining operating expenses. Our principal strategies to maximize revenue include:

    •
    strong focus on resident satisfaction;

    •
    staggering lease terms such that lease expirations are better matched to traffic patterns;

    •
    balancing high occupancy with premium pricing, and increasing rents as market conditions permit; and

    •
    employing revenue management software to optimize the pricing and term of leases.

        Constraining growth in operating expenses is another way in which we seek to increase earnings growth. Growth in our portfolio and the resulting increase in revenue allows for fixed operating costs to be spread over a larger volume of revenue, thereby increasing operating margins. We constrain growth in operating expenses in a variety of ways, which include, but are not limited to, the following:

    •
    we use purchase order controls, acquiring goods and services from pre-approved vendors;

    •
    we use national negotiated contracts and also purchase supplies in bulk where possible;

    •
    we bid third-party contracts on a volume basis;

    •
    we strive to retain residents through high levels of service in order to eliminate the cost of preparing an apartment home for a new resident and to reduce marketing and vacant apartment utility costs;

    •
    we perform turnover work in-house or hire third parties, generally depending upon the least costly alternative;

    •
    we undertake preventive maintenance regularly to maximize resident satisfaction and property and equipment life; and

    •
    we aggressively pursue real estate tax appeals.

        On-site property management teams receive bonuses based largely upon the net operating income ("NOI") produced at their respective communities. We use and continuously seek ways to improve technology applications to help manage our communities, believing that the accurate collection of financial and resident data will enable us to maximize revenue and control costs through careful leasing decisions, maintenance decisions and financial management.

        We generally manage the operation and leasing activity of our communities directly (although we may use a wholly-owned subsidiary) both for ourselves and the joint ventures and partnerships of which we are a member or a partner.

        From time to time we also pursue or arrange ancillary services for our residents to provide additional revenue sources or increase resident satisfaction. As a REIT, we generally cannot provide direct services to our residents that are not customarily provided by a landlord, nor can we directly share in the income of a third party that provides such services. However, we can provide such non-customary services to residents or share in the revenue from such services if we do so through a

5


Table of Contents

"taxable REIT subsidiary," which is a subsidiary that is treated as a "C corporation" subject to federal income taxes.

        Financing Strategy.    We maintain a capital structure that provides financial flexibility to ensure we can select cost effective capital market options that are well matched to our business risks. We estimate that our short-term liquidity needs will be met from cash on hand, borrowings under our $1,300,000,000 revolving variable rate unsecured credit facility (the "Credit Facility"), sales of current operating communities and/or issuance of additional debt or equity securities. A determination to engage in an equity or debt offering depends on a variety of factors such as general market and economic conditions, our short and long-term liquidity needs, the relative costs of debt and equity capital and growth opportunities. A summary of debt and equity activity for the last three years is reflected on our Consolidated Statement of Cash Flows of the Consolidated Financial Statements set forth in Item 8 of this report.

        We have entered into, and may continue in the future to enter into, joint ventures (including limited liability companies or partnerships) through which we would own an indirect economic interest of less than 100% of the community or communities owned directly by such joint ventures. Our decision to either hold an apartment community in fee simple or to have an indirect interest in the community through a joint venture is based on a variety of factors and considerations, including: (i) the economic and tax terms required by a seller of land or of a community; (ii) our desire to diversify our portfolio of communities by market, submarket and product type; (iii) our desire at times to preserve our capital resources to maintain liquidity or balance sheet strength; and (iv) our projection, in some circumstances, that we will achieve higher returns on our invested capital or reduce our risk if a joint venture vehicle is used. Investments in joint ventures are not limited to a specified percentage of our assets. Each joint venture agreement is individually negotiated, and our ability to operate and/or dispose of a community in our sole discretion may be limited to varying degrees depending on the terms of the joint venture agreement.

        In addition, from time to time, we may offer shares of our equity securities, debt securities or options to purchase stock in exchange for property. We may also acquire properties in exchange for properties we currently own.

        Other Strategies and Activities.    While we emphasize equity real estate investments in rental apartment communities, we have the ability to invest in other types of real estate, mortgages (including participating or convertible mortgages), securities of other REITs or real estate operating companies, or securities of technology companies that relate to our real estate operations or of companies that provide services to us or our residents, in each case consistent with our qualification as a REIT. In addition, we own and lease retail space at our communities when either (i) the highest and best use of the space is for retail (e.g., street level in an urban area); (ii) we believe the retail space will enhance the attractiveness of the community to residents or; (iii) some component of retail space is required to obtain entitlements to build apartment homes. As of December 31, 2012, we had a total of 458,693 square feet of rentable retail space, excluding retail space within communities currently under construction. Gross rental revenue provided by leased retail space in 2012 was $8,806,000 (0.8% of total revenue). We may also develop a property in conjunction with another real estate company that will own and operate the retail component of a mixed-use building that we help develop. If we secure a development right and believe that its best use, in whole or in part, is to develop the real estate with the intent to sell rather than hold the asset, we may, through a taxable REIT subsidiary, develop real estate for sale. Any investment in securities of other entities, and any development of real estate for sale, is subject to the percentage of ownership limitations, gross income tests, and other limitations that must be observed for REIT qualification.

        We have not engaged in trading, underwriting or agency distribution or sale of securities of other issuers and do not intend to do so. At all times we intend to make investments in a manner so as to

6


Table of Contents

qualify as a REIT unless, because of circumstances or changes to the Internal Revenue Code of 1986 (or the Treasury Regulations), our Board of Directors determines that it is no longer in our best interest to qualify as a REIT.

Archstone Acquisition

        In November 2012, we entered into agreements with (i) Equity Residential and its operating partnership, ERP Operating Partnership LP ("Equity Residential"), (ii) Lehman Brothers Holdings, Inc., ("Lehman"), and (iii) Archstone Enterprise LP ("Archstone"), pursuant to which AvalonBay and Equity Residential will acquire, directly or indirectly, all of the assets, liabilities and ownership interests in joint ventures or other entities owned by Archstone. Under the terms of the agreements, we will acquire approximately 40% of Archstone's assets and liabilities and Equity Residential will acquire approximately 60% of Archstone's assets and liabilities ("Archstone Acquisition"). The transaction is expected to close during the first quarter of 2013.

        As disclosed in November 2012, we expect to purchase the following as part of the Archstone Acquisition, which is subject to adjustment up until the transaction closes:

    •
    66 apartment communities that are expected to be consolidated for financial reporting purposes, containing 22,222 apartment homes, of which six communities are under construction and are expected to contain 1,666 apartment homes upon completion

    •
    Three parcels of land, which are expected to be wholly owned, and if developed as anticipated, are expected to contain a total of 968 apartment homes;

    •
    Interests in joint ventures the assets of which consist primarily of real estate, for which our ownership percentage is expected to be up to 40%, and that are not expected to be consolidated for financial reporting purposes.

        The Company expects to provide the following consideration for the Archstone Acquisition:

    •
    the issuance of 14,889,706 shares of its common stock to Lehman or its designees;

    •
    cash payment of $669,000,000 to Lehman or its designees;

    •
    the assumption of approximately $3,700,000,000 principal amount of consolidated indebtedness;

    •
    the acquisition with Equity Residential of interests in entities that have preferred units outstanding that may be presented for redemption from time to time. The Company's 40% share of the liquidation value of and accrued dividends on these outstanding Archstone preferred units as of January 31, 2013 was $132,200,000; and

    •
    the assumption with Equity Residential of all other liabilities, known or unknown, of Archstone, other than certain excluded liabilities. The Company will share in 40% of the cost of these liabilities.

        Equity Residential and we are jointly and severally liable for most obligations to Lehman related to the Archstone Acquisition. If we and Equity Residential fail to close Archstone Acquisition by March 26, 2013, then Equity Residential and we could be liable for payment of a termination fee of $800,000,000. The closing of the transaction is also subject to customary closing conditions, which do not include our and Equity Residential's ability to obtain the necessary financing or lender consents for the transaction. Unless otherwise stated, all amounts and disclosures included in this Form 10-K do not include any impact from the anticipated closing of the Archstone Acquisition.

Tax Matters

        We filed an election with our 1994 federal income tax return to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, ("the Code") and intend to maintain our qualification as a REIT in the future. As a qualified REIT, with limited exceptions, we will not be taxed under federal and certain state income tax laws at the corporate level on our taxable net income to the extent taxable net income is distributed to our stockholders. We expect to make sufficient distributions to avoid income tax at the corporate level. While we believe that we are organized and qualified as a REIT and we intend to operate in a manner that will allow us to continue to qualify as a REIT, there can be no assurance that we will be successful in this regard. Qualification as a REIT involves the application of highly technical and complex provisions of the Code for which there are limited judicial and administrative interpretations and involves the determination of a variety of factual matters and circumstances not entirely within our control.

Competition

        We face competition from other real estate investors, including insurance companies, pension and investment funds, partnerships and investment companies and other REITs, to acquire and develop apartment communities and acquire land for future development. As an owner and operator of apartment communities, we also face competition for prospective residents from other operators whose communities may be perceived to offer a better location or better amenities or whose rent may be perceived as a better value given the quality, location and amenities that the resident seeks. We also compete against condominiums and single-family homes that are for sale or rent. Although we often compete against large sophisticated developers and operators for development opportunities and for prospective residents, real estate developers and operators of any size can provide effective competition for both real estate assets and potential residents.

Environmental and Related Matters

        As a current or prior owner, operator and developer of real estate, we are subject to various federal, state and local environmental laws, regulations and ordinances and also could be liable to third parties resulting from environmental contamination or noncompliance at our communities. For some development communities we undertake extensive environmental remediation to prepare the site for construction, which could be a significant portion of our total construction cost. Environmental remediation efforts could expose us to possible liabilities for accidents or improper handling of contaminated materials during construction. These and other risks related to environmental matters are described in more detail in Item 1a., "Risk Factors."

        We believe that more government regulation of energy use, along with a greater focus on environmental protection, may, over time, have a significant impact on urban growth patterns. If changes in zoning to encourage greater density and proximity to mass transit do occur, such changes could benefit multifamily housing and those companies with a competency in high-density development. However, there can be no assurance as to whether or when such changes in regulations or zoning will occur or, if they do occur, whether the multifamily industry or the Company will benefit from such changes.

ITEM 1a.    RISK FACTORS

        Our operations involve various risks that could have adverse consequences, including those described below. This Item 1a. includes forward-looking statements. You should refer to our discussion of the qualifications and limitations on forward-looking statements in this Form 10-K.

We may fail to consummate the Archstone Acquisition or may not consummate it on the terms described in this report.

        We expect to consummate the Archstone Acquisition during the first quarter of 2013, assuming that all of the conditions in the related asset purchase agreement (the "Purchase Agreement") are satisfied or waived. The consummation of the Archstone Acquisition, however, is subject to certain closing conditions, including conditions that must be met by Equity Residential and which are beyond our control, and there can be no assurance that such conditions will be satisfied on the anticipated schedule or at all. In addition, under certain circumstances, we or Lehman may terminate the Purchase Agreement. As a result, there can be no assurance that the Archstone Acquisition will be consummated in its entirety in accordance with the anticipated timing or at all.

        In addition, if the Archstone Acquisition does not occur we will not recover our costs and expenses incurred in connection with the transaction and we may be liable for all or a portion of the $800,000,000 termination fee, if payable.

We and/or Equity Residential may fail to perform under the Purchase Agreement or may not perform on the terms prescribed.

        We don't believe that we could meet, or that Equity Residential could meet, the obligations, as buyer, set forth in the Purchase Agreement without the timely performance of the other. Thus, we and Equity Residential are each dependent upon the performance of the other to meet the buyer's obligations under the Purchase Agreement. A default by either party under the Purchase Agreement could give rise to adverse consequences to the breaching party pursuant to certain arrangements between us and Equity Residential. Under our arrangements with Equity Residential, if the termination of the Purchase Agreement is solely a result of a breach by either us or Equity Residential then the breaching party shall be solely responsible for, and shall indemnify the non-breaching party against, the fees and expenses, including the termination fee of up to $800,000,000, payable to Lehman resulting from a failure to consummate the acquisition, and any out-of-pocket expenses incurred by such non-breaching party in connection with enforcing its rights against the breaching party.

Our business and the market price of our common stock may be adversely affected if the Archstone Acquisition is not completed.

        The Archstone Acquisition is subject to customary closing conditions. If the Archstone Acquisition is not completed, we could be subject to a number of risks that may adversely affect our business and the market price of our common stock, including:

    •
    the market price of our common stock may decline to the extent that the current market price reflects an assumption that the Archstone Acquisition will be completed;

    •
    we must pay certain costs related to the Archstone Acquisition, such as legal and accounting fees and expenses, regardless of whether the Archstone Acquisition is consummated;

    •
    we would not realize the benefits we expect to realize from consummating the Archstone Acquisition; and

    •
    we, together with Equity Residential, may be liable for a termination fee of up to $800,000,000.

10


Table of Contents

We will incur substantial expenses and payments even if the Archstone Acquisition is not completed.

        We have incurred substantial legal, accounting, financial advisory and other costs and our management has devoted considerable time and effort in connection with the Archstone Acquisition. If the Archstone Acquisition is not completed, we will bear certain fees and expenses associated with the Archstone Acquisition without realizing the benefits of the Archstone Acquisition. The fees and expenses may be significant and could have an adverse impact on our operating results. For instance, if Lehman terminates the Purchase Agreement due to a breach by us or a failure by us to satisfy a condition precedent to Lehman's obligation to close the Archstone Acquisition, we would be obligated to pay to Lehman a termination fee of up to $800,000,000.

We intend to assume indebtedness in connection with the Archstone Acquisition, which may have an adverse effect on our financial condition and results of operations, and our ability to make distributions to our stockholders.

        We intend to assume $3,700,000,000 principal amount of consolidated indebtedness in connection with the Archstone Acquisition, which will increase our leverage and the ratio of our net debt to our earnings before interest, tax, depreciation and amortization.

        We expect to repay contemporaneously with the closing up to $1,700,000,000 principal amount of assumed indebtedness from the Archstone Acquisition. However, there can be no assurance that we will be able to reduce or refinance, over time, to the extent we anticipate, the indebtedness we are assuming. Therefore, the increase in indebtedness we will incur at closing of the Archstone Acquisition could have adverse consequences on our business, such as:

    •
    requiring us to use a substantial portion of our cash flow from operations to service our indebtedness, which would reduce the available cash flow to fund working capital, capital expenditures, development projects and other general corporate purposes such as dividends;

    •
    limiting our ability to obtain additional financing to fund our working capital needs, acquisitions, capital expenditures or other debt service requirements or for other purposes;

    •
    limiting our ability to compete with other companies that are not as highly leveraged, as we may be less capable of responding to adverse economic and industry conditions;

    •
    restricting us from making other strategic acquisitions, developing additional properties or exploiting other business opportunities;

    •
    restricting the way in which we conduct our business because of financial and operating covenants in the agreements governing our and our subsidiaries' existing and future indebtedness;

    •
    exposing us to potential events of default (if not cured or waived) under financial and operating covenants contained in our or our subsidiaries' debt instruments that could have an adverse effect on our business, financial condition and operating results;

    •
    increasing our vulnerability to a downturn in general economic conditions; and

    •
    limiting our ability to react to changing market conditions in our industry.

        In addition to our debt service obligations, our operations may require substantial investments on a continuing basis. Our ability to make scheduled debt payments, to refinance our obligations with respect to our indebtedness and to fund capital and non-capital expenditures necessary to maintain the condition of our operating assets and properties, as well as to provide capacity for the growth of our business, depends on our financial and operating performance, which, in turn, is subject to prevailing economic conditions and financial, business, competitive, legal and other factors.

Table of Contents

The intended benefits of the Archstone Acquisition may not be realized, which could have a negative impact on the market price of our common stock after the Archstone Acquisition.

        The Archstone Acquisition poses risks for our ongoing operations, including that:

    •
    our senior management's attention may be diverted from the management of daily operations to the integration of the Archstone Acquisition, including management of assets located outside of our core markets pending disposition, which may disrupt management of our existing business and our relationships with our customers;

    •
    we may bear costs and expenses associated with any undisclosed or potential liabilities;

    •
    the Archstone Acquisition may not perform as well as we anticipate; and

    •
    unforeseen difficulties may arise in integrating the Archstone Acquisition into our portfolio.

        Also, we expect to acquire assets and assume liabilities in connection with the Archstone Acquisition on an "as is" basis with only limited representations from Lehman surviving after the closing of the Archstone Acquisition, which limits our recourse against the seller for breaches of representations after closing, which in turn may expose us to unexpected material losses or expenses after the closing.

        In addition, our diligence investigations with respect to the assets comprising the Archstone Acquisition, has been more limited than would be the case if we were acquiring individual apartment communities or land parcels, which may also expose us to unexpected material losses or expenses after the closing.

        As a result of the foregoing, we cannot assure you that the Archstone Acquisition will be accretive to us in the near term or at all. Furthermore, if we fail to realize the intended benefits of the Archstone Acquisition, the market price of our common stock could decline to the extent that the market price reflects those anticipated benefits.

The Archstone Acquisition will significantly increase the size of our real estate portfolio and related personnel and operating and financial needs, and we may not be successful in integrating the Archstone Acquisition into our business.

        The Archstone Acquisition involves a variety of risks, including potential difficulties in integrating the portfolio, diversions of our management resources, differing levels of management and internal control effectiveness at the acquired entities and other unanticipated problems and liabilities. Any of these risks could adversely affect our financial results and reduce or delay our ability to obtain the expected benefits of the Archstone Acquisition.

        In addition, the increased need for financial resources that will result from the Archstone Acquisition, as well as the diversion of our management resources, may affect our existing development, redevelopment and acquisition portfolios and development rights pipeline. As a result, there may be unexpected delays in the timing of our activities relating to our existing real estate portfolios and development rights pipeline, and we may encounter unexpected costs or we may not succeed in obtaining the expected benefits of our currently expected real estate development, redevelopment and acquisition activities. These issues could also increase our capital requirements, which may require us to issue potentially dilutive equity securities and incur additional debt.

The governance provisions of our joint ventures with Equity Residential could adversely affect our flexibility in dealing with such joint venture assets and liabilities.

        In connection with the Archstone Acquisition, we expect to create joint ventures with Equity Residential to manage certain of the acquired assets and liabilities. These structures involve

12


Table of Contents

participation in the investment by Equity Residential whose interests and rights may not be the same as ours. Joint ownership of an investment in real estate involves risks not associated with direct ownership of real estate, including the risk that Equity Residential may at any time have economic or other business interests or goals which become inconsistent with our business interests or goals, including inconsistent goals relating to the sale of properties held in the joint ventures or the timing of the termination and liquidation of the joint ventures. Under the expected form for the joint venture arrangements, neither we nor Equity Residential expect to have the power to control the ventures, and an impasse could occur, which would adversely affect the applicable joint venture and decrease potential returns to us and our investors.

We expect to assume substantially all liabilities related to the Archstone Acquisition, and may be responsible for liabilities that were not known when we entered into the Purchase Agreement.

        Under the Purchase Agreement, we and Equity Residential will assume substantially all liabilities related to the Archstone portfolio, whether or not they were known by us and Equity Residential at the time we entered into the Purchase Agreement, and we have agreed to indemnify Lehman with respect to these liabilities. Under the Purchase Agreement, we would be solely liable for these obligations if Equity Residential were to default on its obligation to share these indemnification obligations with us. As a result, we could become liable for liabilities that are not currently known to us, and the amount of these liabilities could have an adverse effect on our business, financial condition and results of operations.

We intend to dispose of certain assets acquired in connection with the Archstone Acquisition, but we may be unable to achieve the expected proceeds of these acquisitions or may be unable to dispose of these assets at all.

        We intend to dispose of certain assets acquired in connection with the Archstone Acquisition, including assets held in our joint ventures with Equity Residential, but we cannot predict whether we will be able to sell any of the properties on favorable terms and conditions, if at all, or the length of time over which we expect to sell any of the assets. We may be unable to sell some of the properties, which may adversely affect our liquidity, or we may have to sell properties at depressed prices, which could adversely affect our results of operations and financial condition. Our joint ventures with Equity Residential will own, among other assets, investments in apartment communities in Germany, and we will acquire from Archstone interests in U.S. markets that we are not currently in, including Florida, Georgia and Texas. Our efforts to manage, position and/or dispose of these investments may distract management and we may not achieve the intended results.

Future sales or issuances of our common stock may cause the market price of our common stock to decline.

        In connection with the Archstone Acquisition, we will issue shares of our common stock under the Purchase Agreement, and we will be required to register the resale of such shares of common stock under the Securities Act. The sale of substantial amounts of our common stock, whether directly by us or in the secondary market, the perception that such sales could occur or the availability for future sale of shares of our common stock or securities convertible into or exchangeable or exercisable for our common stock, could adversely affect the market price of our common stock and our ability to raise capital through future offerings of equity or equity-related securities.

Development, redevelopment and construction risks could affect our profitability.

        We intend to continue to develop and redevelop apartment home communities. These activities can include long planning and entitlement timelines and can involve complex and costly activities,

13


Table of Contents

including significant environmental remediation or construction work in high-density urban areas. These activities may be exposed to the following risks:

    •
    we may abandon opportunities that we have already begun to explore for a number of reasons, including changes in local market conditions or increases in construction or financing costs, and, as a result, we may fail to recover expenses already incurred in exploring those opportunities;

    •
    occupancy rates and rents at a community may fail to meet our original expectations for a number of reasons, including changes in market and economic conditions beyond our control and the development by competitors of competing communities;

    •
    we may be unable to obtain, or experience delays in obtaining, necessary zoning, occupancy, or other required governmental or third party permits and authorizations, which could result in increased costs or the delay or abandonment of opportunities;

    •
    we may incur costs that exceed our original estimates due to increased material, labor or other costs;

    •
    we may be unable to complete construction and lease-up of a community on schedule, resulting in increased construction and financing costs and a decrease in expected rental revenues;

    •
    we may be unable to obtain financing with favorable terms, or at all, for the proposed development of a community, which may cause us to delay or abandon an opportunity;

    •
    we may incur liabilities to third parties during the development process, for example, in connection with managing existing improvements on the site prior to tenant terminations and demolition (such as commercial space) or in connection with providing services to third parties (such as the construction of shared infrastructure or other improvements); and

    •
    we may incur liability if our communities are not constructed and operated in compliance with the accessibility provisions of the Americans with Disabilities Acts, the Fair Housing Act or other federal, state or local requirements. Noncompliance could result in imposition of fines, an award of damages to private litigants, and a requirement that we undertake structural modifications to remedy the noncompliance.

        We estimate construction costs based on market conditions at the time we prepare our budgets, and our projections include changes that we anticipate but cannot predict with certainty. Construction costs may increase, particularly for labor and certain materials and, for some of our Development Communities and Development Rights (as defined below), the total construction costs may be higher than the original budget. Total capitalized cost includes all capitalized costs incurred and projected to be incurred to develop or redevelop a community, determined in accordance with GAAP, including:

    •
    land and/or property acquisition costs;

    •
    fees paid to secure air rights and/or tax abatements;

    •
    construction or reconstruction costs;

    •
    costs of environmental remediation;

    •
    real estate taxes;

    •
    capitalized interest and insurance;

    •
    loan fees;

    •
    permits;

    •
    professional fees;

14


Table of Contents

    •
    allocated development or redevelopment overhead; and

    •
    other regulatory fees.

        Costs to redevelop communities that have been acquired have, in some cases, exceeded our original estimates and similar increases in costs may be experienced in the future. We cannot assure you that market rents in effect at the time new development or redevelopment communities complete lease-up will be sufficient to fully offset the effects of any increased construction or reconstruction costs.

Unfavorable changes in market and economic conditions could adversely affect occupancy, rental rates, operating expenses, and the overall market value of our assets, including joint ventures and investments in the Funds.

        Local conditions in our markets significantly affect occupancy, rental rates and the operating performance of our communities. The risks that may adversely affect conditions in those markets include the following:

    •
    plant closings, industry slowdowns and other factors that adversely affect the local economy;

    •
    an oversupply of, or a reduced demand for, apartment homes;

    •
    a decline in household formation or employment or lack of employment growth;

    •
    the inability or unwillingness of residents to pay rent increases;

    •
    rent control or rent stabilization laws, or other laws regulating housing, that could prevent us from raising rents to offset increases in operating costs; and

    •
    economic conditions that could cause an increase in our operating expenses, such as increases in property taxes, utilities, compensation of on-site associates and routine maintenance.

Changes in applicable laws, or noncompliance with applicable laws, could adversely affect our operations or expose us to liability.

        We must develop, construct and operate our communities in compliance with numerous federal, state and local laws and regulations, some of which may conflict with one another or be subject to limited judicial or regulatory interpretations. These laws and regulations may include zoning laws, building codes, landlord tenant laws and other laws generally applicable to business operations. Noncompliance with laws could expose us to liability.

        Lower revenue growth or significant unanticipated expenditures may result from our need to comply with changes in (i) laws imposing remediation requirements and the potential liability for environmental conditions existing on properties or the restrictions on discharges or other conditions, (ii) rent control or rent stabilization laws or other residential landlord/tenant laws, or (iii) other governmental rules and regulations or enforcement policies affecting the development, use and operation of our communities, including changes to building codes and fire and life-safety codes.

Short-term leases expose us to the effects of declining market rents.

        Substantially all of our apartment leases are for a term of one year or less. Because these leases generally permit the residents to leave at the end of the lease term without penalty, our rental revenues are impacted by declines in market rents more quickly than if our leases were for longer terms.

15


Table of Contents

Competition could limit our ability to lease apartment homes or increase or maintain rents.

        Our apartment communities compete with other housing alternatives to attract residents, including other rental apartments, condominiums and single-family homes that are available for rent, as well as new and existing condominiums and single-family homes for sale. Competitive residential housing in a particular area could adversely affect our ability to lease apartment homes and to increase or maintain rental rates.

Attractive investment opportunities may not be available, which could adversely affect our profitability.

        We expect that other real estate investors, including insurance companies, pension funds, other REITs and other well-capitalized investors, will compete with us to acquire existing properties and to develop new properties. This competition could increase prices for properties of the type we would likely pursue and adversely affect our profitability.

Capital and credit market conditions may adversely affect our access to various sources of capital and/or the cost of capital, which could impact our business activities, dividends, earnings, and common stock price, among other things.

        In periods when the capital and credit markets experience significant volatility, the amounts, sources and cost of capital available to us may be adversely affected. We primarily use external financing to fund construction and to refinance indebtedness as it matures. If sufficient sources of external financing are not available to us on cost effective terms, we could be forced to limit our development and redevelopment activity and/or take other actions to fund our business activities and repayment of debt, such as selling assets, reducing our cash dividend or paying out less than 100% of our taxable income. To the extent that we are able and/or choose to access capital at a higher cost than we have experienced in recent years (reflected in higher interest rates for debt financing or a lower stock price for equity financing) our earnings per share and cash flows could be adversely affected. In addition, the price of our common stock may fluctuate significantly and/or decline in a high interest rate or volatile economic environment. We believe that the lenders under our Credit Facility will fulfill their lending obligations thereunder, but if economic conditions deteriorate, there can be no assurance that the ability of those lenders to fulfill their obligations would not be adversely impacted.

Insufficient cash flow could affect our debt financing and create refinancing risk.

        We are subject to the risks associated with debt financing, including the risk that our cash flow will be insufficient to meet required payments of principal and interest. In this regard, we note that in order for us to continue to qualify as a REIT, we are required to annually distribute dividends generally equal to at least 90% of our REIT taxable income, computed without regard to the dividends paid deduction and our net capital gain. This requirement limits the amount of our cash flow available to meet required principal and interest payments. The principal outstanding balance on a portion of our debt will not be fully amortized prior to its maturity. Although we may be able to repay our debt by using our cash flows, we cannot assure you that we will have sufficient cash flows available to make all required principal payments. Therefore, we may need to refinance at least a portion of our outstanding debt as it matures. There is a risk that we may not be able to refinance existing debt or that a refinancing will not be done on as favorable terms; either of these outcomes could have a material adverse effect on our financial condition and results of operations.

Rising interest rates could increase interest costs and could affect the market price of our common stock.

        We currently have, and may in the future incur, contractual variable interest rate debt. In addition, we regularly seek access to both fixed and variable rate debt financing to repay maturing debt and to finance our development and redevelopment activity. Accordingly, if interest rates increase, our interest costs will also rise, unless we have made arrangements that hedge the risk of rising interest rates. In addition, an increase in market interest rates may lead purchasers of our common stock to demand a greater annual dividend yield, which could adversely affect the market price of our common stock.

16


Table of Contents

Bond financing and zoning compliance requirements could limit our income, restrict the use of communities and cause favorable financing to become unavailable.

        We have financed some of our apartment communities with obligations issued by local government agencies because the interest paid to the holders of this debt is generally exempt from federal income taxes and, therefore, the interest rate is generally more favorable to us. These obligations are commonly referred to as "tax-exempt bonds" and generally must be secured by mortgages on our communities. As a condition to obtaining tax-exempt financing, or on occasion as a condition to obtaining favorable zoning in some jurisdictions, we will commit to make some of the apartments in a community available to households whose income does not exceed certain thresholds (e.g., 50% or 80% of area median income), or who meet other qualifying tests. As of December 31, 2012, approximately 6.47% of our apartment homes at current operating communities were under income limitations such as these. These commitments, which may run without expiration or may expire after a period of time (such as 15 or 20 years) may limit our ability to raise rents and, in consequence, can also adversely affect the value of the communities subject to these restrictions.

        In addition, some of our tax-exempt bond financing documents require us to obtain a guarantee from a financial institution of payment of the principal of, and interest on, the bonds. The guarantee may take the form of a letter of credit, surety bond, guarantee agreement or other additional collateral. If the financial institution defaults in its guarantee obligations, or if we are unable to renew the applicable guarantee or otherwise post satisfactory collateral, a default will occur under the applicable tax-exempt bonds and the community could be foreclosed upon if we do not redeem the bonds.

Risks related to indebtedness.

        We have a Credit Facility with Bank of America, N.A., as administrative agent, swing lender, issuing bank and a bank, JPMorgan Chase Bank, N.A., as a bank and as syndication agent, Deutsche Bank Trust Company Americas, Morgan Stanley Bank and Wells Fargo Bank, N.A., each as a bank and as documentation agent, Barclays Bank PLC as a bank and as co-documentation agent, UBS AG, Stamford Branch, as a co-documentation agent, Goldman Sachs Bank USA, The Bank of New York Mellon, Compass Bank, PNC Bank, National Association, and Suntrust Bank, each as a bank and as a managing agent, Branch Banking and Trust Company, Bank of Tokyo Mitsubishi UFJ, Ltd., and Capital One, N.A., each as a bank and as a co-agent, and the other bank parties signatory thereto. Our organizational documents do not limit the amount or percentage of indebtedness that may be incurred. Accordingly, subject to compliance with outstanding debt covenants, we could incur more debt, resulting in an increased risk of default on our obligations and an increase in debt service requirements that could adversely affect our financial condition and results of operations.

        The mortgages on those of our properties that are subject to secured debt, our Credit Facility and the indenture under which a substantial portion of our debt was issued contain customary restrictions, requirements and other limitations, as well as certain financial and operating covenants including maintenance of certain financial ratios. Maintaining compliance with these restrictions could limit our flexibility. A default in these requirements, if uncured, could result in a requirement that we repay indebtedness, which could severely affect our liquidity and increase our financing costs. Refer to Item 7., "Management's Discussion and Analysis of Financial Condition and Results of Operations," for further discussion.

        The mortgages on those of our properties subject to secured debt generally include provisions which stipulate a prepayment penalty or payment that we will be obligated to pay in the event that we elect to repay the mortgage note prior to the earlier of (i) the stated maturity of the note, or (ii) the date at which the mortgage note is prepayable without such penalty or payment. If we elect to repay some or all of the outstanding principal balance for our mortgage notes, we may incur prepayment penalties or payments under these provisions which could adversely affect our results of operations.

Table of Contents

Failure to maintain our current credit ratings could adversely affect our cost of funds, related margins, liquidity and access to capital markets.

        There are two major debt rating agencies that routinely evaluate and rate our debt. These ratings are based on a number of factors, which include their assessment of our financial strength, liquidity, capital structure, asset quality amount of real estate under development, and sustainability of cash flow and earnings, among other factors. If market conditions change, we may not be able to maintain our current credit ratings, which could adversely affect our cost of funds and related margins, liquidity, and access to capital markets.

We could be negatively impacted by the condition of Fannie Mae or Freddie Mac.

        Fannie Mae and Freddie Mac are a major source of secured financing to the multifamily industry and we have used Fannie Mae and Freddie Mac for a portion of our financing needs. In February 2011, the Obama administration released a report calling for the winding down of the role that Fannie Mae and Freddie Mac play in the mortgage market. A final decision by the government to eliminate Fannie Mae or Freddie Mac or reduce their acquisitions or guarantees of multifamily community loans may adversely affect interest rates, capital availability, and the value of multifamily communities.

Debt financing may not be available and equity issuances could be dilutive to our stockholders.

        Our ability to execute our business strategy depends on our access to an appropriate blend of debt and equity financing. Debt financing may not be available in sufficient amounts or on favorable terms. If we issue additional equity securities, the interests of existing stockholders could be diluted.

Failure to generate sufficient revenue or other liquidity needs could limit cash flow available for distributions to stockholders.

        A decrease in rental revenue, or liquidity needs such as the repayment of indebtedness or funding of our development activities, could have an adverse effect on our ability to pay distributions to our stockholders. Significant expenditures associated with each community such as debt service payments, if any, real estate taxes, insurance and maintenance costs are generally not reduced when circumstances cause a reduction in income from a community.

The form, timing and/or amount of dividend distributions in future periods may vary and be impacted by economic and other considerations.

        The form, timing and/or amount of dividend distributions will be declared at the discretion of the Board of Directors and will depend on actual cash from operations, our financial condition, capital requirements, the annual distribution requirements under the REIT provisions of the Code and other factors as the Board of Directors may consider relevant. The Board of Directors may modify our dividend policy from time to time.

We may choose to pay dividends in our own stock, in which case stockholders may be required to pay tax in excess of the cash they receive.

        We may distribute taxable dividends that are payable in part in our stock, as we did in the fourth quarter of 2008. Taxable stockholders receiving such dividends will be required to include the full amount of the dividend as income to the extent of our current and accumulated earnings and profits for federal income tax purposes. As a result, a U.S. stockholder may be required to pay tax with respect to such dividends in excess of the cash received. If a U.S. stockholder sells the stock it receives as a dividend in order to pay this tax, the sales proceeds may be less than the amount included in income with respect to the dividend, depending on the market price of our stock at the time of the sale. Furthermore, with respect to non-U.S. stockholders, we may be required to withhold U.S. tax with

18


Table of Contents

respect to such dividends, including in respect of all or a portion of such dividend that is payable in stock. In addition, the trading price of our stock would experience downward pressure if a significant number of our stockholders sell shares of our stock in order to pay taxes owed on dividends.

Difficulty of selling apartment communities could limit liquidity and financial flexibility.

        Federal tax laws may limit our ability to earn a gain on the sale of a community (unless we own it through a subsidiary which will incur a taxable gain upon sale) if we are found to have held, acquired or developed the community primarily with the intent to resell the community, and this limitation may affect our ability to sell communities without adversely affecting returns to our stockholders. In addition, real estate in our markets can at times be difficult to sell quickly at prices we find acceptable. These potential difficulties in selling real estate in our markets may limit our ability to change or reduce the apartment communities in our portfolio promptly in response to changes in economic or other conditions.

Acquisitions may not yield anticipated results.

        Our business strategy includes acquiring as well as developing communities. Our acquisition activities and their success may be exposed to the following risks:

    •
    an acquired property may fail to perform as we expected in analyzing our investment; and

    •
    our estimate of the costs of repositioning or redeveloping an acquired property may prove inaccurate.

Failure to succeed in new markets, or with new brands and community formats, or in activities other than the development, ownership and operation of residential rental communities may have adverse consequences.

        We may from time to time commence development activity or make acquisitions outside of our existing market areas if appropriate opportunities arise. Our historical experience in our existing markets in developing, owning and operating rental communities does not ensure that we will be able to operate successfully in new markets, should we choose to enter them. We may be exposed to a variety of risks if we choose to enter new markets, including an inability to accurately evaluate local apartment market conditions; an inability to obtain land for development or to identify appropriate acquisition opportunities; an inability to hire and retain key personnel; and lack of familiarity with local governmental and permitting procedures.

        Although we are primarily in the multifamily business, we also own and lease ancillary retail space when a retail component represents the best use of the space, as is often the case with large urban in-fill developments. We also may engage or have an interest in for-sale activity. We may be unsuccessful in owning and leasing retail space at our communities or in developing real estate with the intent to sell, which could have an adverse effect on our results of operations.

        We are currently implementing two new brands of communities that target various customer preferences. We cannot assure that these brands will be successful or that our costs in developing and implementing these brands will result in incremental revenue and earnings.

Land we hold with no current intent to develop may be subject to future impairment charges.

        We own parcels of land that we do not currently intend to develop. As discussed in Item 2., "Communities—Other Land and Real Estate Assets," in the event that the fair market value of a parcel changes such that we determine that the carrying basis of the parcel reflected in our financial statements is greater than the parcel's then current fair value, less costs to dispose, we would be subject to an impairment charge, which would reduce our net income.

Risks involved in real estate activity through joint ventures.

        Instead of acquiring or developing apartment communities directly, at times we invest as a partner or a co-venturer. Joint venture investments (including investments through partnerships or limited liability companies) involve risks, including the possibility that our partner might become insolvent or otherwise refuse to make capital contributions when due; that we may be responsible to our partner for indemnifiable losses; that our partner might at any time have business goals which are inconsistent with ours; and that our partner may be in a position to take action or withhold consent contrary to our instructions or requests. Frequently, we and our partner may each have the right to trigger a buy-sell arrangement, which could cause us to sell our interest, or acquire our partner's interest, at a time when we otherwise would not have initiated such a transaction.

Risks associated with an investment in and management of discretionary real estate investment funds.

        We formed Fund I and Fund II, in which we have an equity interest of 15.2% and 31.3%, respectively, which, through wholly-owned subsidiaries, we manage as the general partner and in which we have an aggregate equity investment, excluding costs incurred in excess of our equity in the underlying net assets of each respective fund, of approximately $129,059,000, net of distributions to us at December 31, 2012. The investment period for both Funds is over. These Funds present risks, including the following:

    •
    our subsidiaries that are the general partners of the Funds are generally liable, under partnership law, for the debts and obligations of the respective Funds, subject to certain exculpation and indemnification rights pursuant to the terms of the partnership agreement of the Funds;

    •
    investors in the Funds holding a majority of the partnership interests may remove us as the general partner without cause, subject to our right to receive an additional nine months of management fees after such removal and our right to acquire one of the properties then held by the Funds;

    •
    while we have broad discretion to manage the Funds and make investment decisions on behalf of the Funds, the investors or an advisory committee comprised of representatives of the investors must approve certain matters, and as a result we may be unable to cause the Funds to implement certain decisions that we consider beneficial; and

    •
    we may be liable and/or our status as a REIT may be jeopardized if either the Funds, or the REITs through which a number of investors have invested in the Funds and which we manage, fail to comply with various tax or other regulatory matters.

Risk of earthquake damage.

        As further described in Item 2., "Communities—Insurance and Risk of Uninsured Losses," many of our West Coast communities are located in the general vicinity of active earthquake faults. We cannot assure you that an earthquake would not cause damage or losses greater than insured levels. In the event of a loss in excess of insured limits, we could lose our capital invested in the affected community, as well as anticipated future revenue from that community. We would also continue to be obligated to repay any mortgage indebtedness or other obligations related to the community. Any such loss could materially and adversely affect our business and our financial condition and results of operations.

        Insurance coverage for earthquakes can be costly due to limited industry capacity. As a result, we may experience shortages in desired coverage levels if market conditions are such that insurance is not available or the cost of insurance makes it, in management's view, economically impractical.

20


Table of Contents

A significant uninsured property or liability loss could have a material adverse effect on our financial condition and results of operations.

        In addition to the earthquake insurance discussed above, we carry commercial general liability insurance, property insurance and terrorism insurance with respect to our communities on terms we consider commercially reasonable. There are, however, certain types of losses (such as losses arising from acts of war) that are not insured, in full or in part, because they are either uninsurable or the cost of insurance makes it, in management's view, economically impractical. If an uninsured property loss or a property loss in excess of insured limits were to occur, we could lose our capital invested in a community, as well as the anticipated future revenues from such community. We would also continue to be obligated to repay any mortgage indebtedness or other obligations related to the community. If an uninsured liability to a third party were to occur, we would incur the cost of defense and settlement with, or court ordered damages to, that third party. A significant uninsured property or liability loss could materially and adversely affect our business and our financial condition and results of operations.

We may incur costs and increased expenses to repair property damage resulting from inclement weather.

        Particularly in New England and the Metro New York/New Jersey area, we are exposed to risks associated with inclement winter weather, including increased costs for the removal of snow and ice, repair of water and wind damage from storms, as well as from delays in construction. In addition, inclement weather could increase the need for maintenance and repair of our communities.

We may incur costs due to environmental contamination or non-compliance.

        Under various federal, state and local environmental and public health laws, regulations and ordinances, we may be required, regardless of knowledge or responsibility, to investigate and remediate the effects of hazardous or toxic substances or petroleum product releases at our properties (including in some cases natural substances such as methane and radon gas) and may be held liable under these laws or common law to a governmental entity or to third parties for property, personal injury or natural resources damages and for investigation and remediation costs incurred as a result of the contamination. These damages and costs may be substantial and may exceed any insurance coverage we have for such events. The presence of such substances, or the failure to properly remediate the contamination, may adversely affect our ability to borrow against, develop, sell or rent the affected property.

        In addition, some environmental laws create or allow a government agency to impose a lien on the contaminated site in favor of the government for damages and costs it incurs as a result of the contamination.

        The development, construction and operation of our communities are subject to regulations and permitting under various federal, state and local laws, regulations and ordinances, which regulate matters including wetlands protection, storm water runoff and wastewater discharge. Such laws and regulations may impose restrictions on the manner in which our communities may be developed, and noncompliance with such laws and regulations may subject us to fines and penalties. We do not currently anticipate that we will incur any material liabilities as a result of noncompliance with these laws.

        Certain federal, state and local laws, regulations and ordinances govern the removal, encapsulation or disturbance of asbestos containing materials ("ACMs") when such materials are in poor condition or in the event of renovation or demolition of a building. These laws and the common law may impose liability for release of ACMs and may allow third parties to seek recovery from owners or operators of real properties for personal injury associated with exposure to ACMs. We are not aware that any ACMs were used in the construction of the communities we developed. ACMs were, however, used in the construction of a number of the communities that we acquired. We implement an operations and

21


Table of Contents

maintenance program at each of the communities at which ACMs are detected. We do not currently anticipate that we will incur any material liabilities as a result of the presence of ACMs at our communities.

        We are aware that some of our communities have lead paint and have implemented an operations and maintenance program at each of those communities. We do not currently anticipate that we will incur any material liabilities as a result of the presence of lead paint at our communities.

        Environmental agencies and third parties may assert claims for remediation or personal injury based on the alleged actual or potential intrusion into buildings of chemical vapors from soils or groundwater underlying or in the vicinity of those buildings or on nearby properties. We currently do not anticipate that we will incur any material liabilities as a result of vapor intrusion at our communities.

        All of our stabilized operating communities, and all of the communities that we are currently developing, have been subjected to at least a Phase I or similar environmental assessment, which generally does not involve invasive techniques such as soil or ground water sampling. These assessments, together with subsurface assessments conducted on some properties, have not revealed, and we are not otherwise aware of, any environmental conditions that we believe would have a material adverse effect on our business, assets, financial condition or results of operations. In connection with our ownership, operation and development of communities, from time to time we undertake substantial remedial action in response to the presence of subsurface or other contaminants, including contaminants in soil, groundwater and soil vapor beneath or affecting our buildings. In some cases, an indemnity exists upon which we may be able to rely if environmental liability arises from the contamination or remediation costs exceed estimates. There can be no assurance, however, that all necessary remediation actions have been or will be undertaken at our properties or that we will be indemnified, in full or at all, in the event that environmental liability arises.

        Mold growth may occur when excessive moisture accumulates in buildings or on building materials, particularly if the moisture problem remains undiscovered or is not addressed over a period of time. Although the occurrence of mold at multifamily and other structures, and the need to remediate such mold, is not a new phenomenon, there has been increased awareness in recent years that certain molds may in some instances lead to adverse health effects, including allergic or other reactions. To help limit mold growth, we educate residents about the importance of adequate ventilation and request or require that they notify us when they see mold or excessive moisture. We have established procedures for promptly addressing and remediating mold or excessive moisture from apartment homes when we become aware of its presence regardless of whether we or the resident believe a health risk is presented. However, we cannot provide assurance that mold or excessive moisture will be detected and remediated in a timely manner. If a significant mold problem arises at one of our communities, we could be required to undertake a costly remediation program to contain or remove the mold from the affected community and could be exposed to other liabilities that may exceed any applicable insurance coverage.

        Additionally, we have occasionally been involved in developing, managing, leasing and operating various properties for third parties. Consequently, we may be considered to have been an operator of such properties and, therefore, potentially liable for removal or remediation costs or other potential costs which relate to the release or presence of hazardous or toxic substances or petroleum products at such properties. We are not aware of any material environmental liabilities with respect to properties managed or developed by us or our predecessors for such third parties.

        We cannot assure you that:

    •
    the environmental assessments described above have identified all potential environmental liabilities;

22


Table of Contents

    •
    no prior owner created any material environmental condition not known to us or the consultants who prepared the assessments;

    •
    no environmental liabilities have developed since the environmental assessments were prepared;

    •
    the condition of land or operations in the vicinity of our communities, such as the presence of underground storage tanks, will not affect the environmental condition of our communities;

    •
    future uses or conditions, including, without limitation, changes in applicable environmental laws and regulations, will not result in the imposition of environmental liability; and

    •
    no environmental liabilities will arise at communities that we have sold for which we may have liability.

Our success depends on key personnel whose continued service is not guaranteed.

        Our success depends in part on our ability to attract and retain the services of executive officers and other personnel. Our executive officers make important capital allocation decisions or recommendations to our Board of Directors from among the opportunities identified by our regional offices. There is substantial competition for qualified personnel in the real estate industry, and the loss of several of our key personnel could adversely affect the Company.

Breaches of our data security could materially harm our business and reputation.

        We collect and retain certain personal information provided by our residents and employees. While we have implemented a variety of security measures to protect the confidentiality of this information and periodically review and improve our security measures, there can be no assurance that we will be able to prevent unauthorized access to this information. Any breach of our data security measures and loss of this information may result in legal liability and costs (including damages and penalties), as well as damage to our reputation, that could materially and adversely affect our business and financial performance.

Failure to qualify as a REIT would cause us to be taxed as a corporation, which would significantly reduce funds available for distribution to stockholders.

        If we fail to qualify as a REIT for federal income tax purposes, we will be subject to federal income tax on our taxable income at regular corporate rates (subject to any applicable alternative minimum tax). In addition, unless we are entitled to relief under applicable statutory provisions, we would be ineligible to make an election for treatment as a REIT for the four taxable years following the year in which we lose our qualification. The additional tax liability resulting from the failure to qualify as a REIT would significantly reduce or eliminate the amount of funds available for distribution to our stockholders. Furthermore, we would no longer be required to make distributions to our stockholders. Thus, our failure to qualify as a REIT could also impair our ability to expand our business and raise capital, and would adversely affect the value of our common stock.

        We believe that we are organized and qualified as a REIT, and we intend to operate in a manner that will allow us to continue to qualify as a REIT. However, we cannot assure you that we are qualified as a REIT, or that we will remain qualified in the future. This is because qualification as a REIT involves the application of highly technical and complex provisions of the Internal Revenue Code for which there are only limited judicial and administrative interpretations and involves the determination of a variety of factual matters and circumstances not entirely within our control. In addition, future legislation, new regulations, administrative interpretations or court decisions may significantly change the tax laws or the application of the tax laws with respect to qualification as a REIT for federal income tax purposes or the federal income tax consequences of this qualification.

23


Table of Contents

        Even if we qualify as a REIT, we will be subject to certain federal, state and local taxes on our income and property and on taxable income that we do not distribute to our shareholders. In addition, we may hold certain assets and engage in certain activities that a REIT could not engage in directly through our taxable REIT subsidiaries, or TRSs, and will be subject to federal income tax at regular corporate rates on the income of those subsidiaries.

        In addition, the Archstone Acquisition presents a risk to our qualification as a REIT. Although we intend to structure our ownership and operations of the assets and entities acquired in connection with the Archstone Acquisition, including our interest in joint ventures with Equity Residential, in a way that would allow us to continue to qualify as a REIT for federal income tax purposes, no assurances can be given that we will be successful.

        As a result of the Archstone Acquisition and our ownership interests in the joint ventures with Equity Residential, we expect to acquire interests in certain assets and earn certain items of income that are not, or may not be, qualifying assets or income for purposes of the REIT asset and income tests. Although we do not expect that the amounts of such non-qualifying assets and income will jeopardize our REIT status, our review of the Archstone Acquisition is on-going, and we may discover additional non-qualifying assets or income. We may not have the immediate right to change the terms of pre-existing arrangements that generate non-qualifying items or may have to incur significant penalties to terminate such arrangements. To maintain our REIT qualification we may be required to hold significant assets acquired in connection with the Archstone Acquisition and some or all of our interests in the joint ventures with Equity Residential through our TRSs. We also may hold certain Archstone Acquisition assets through our TRSs to avoid the risk of incurring the 100% prohibited transaction tax on any such assets that we sell at a gain. Our domestic TRSs are subject to U.S. tax as regular corporations. Among the assets included in the Archstone Acquisition are subsidiaries intended to qualify as REITs. To the extent we hold such subsidiaries outside of our TRSs, our REIT qualification could depend in part on such subsidiaries' compliance with the REIT requirements before our purchase.

        The assets of one of our joint ventures with Equity Residential are expected to include interests in a partnership controlled by Equity Residential. As a result of our ownership interest in that joint venture, for purposes of our compliance with the REIT requirements we will be treated as owning our proportionate share of the assets of the Equity Residential partnership in which the joint venture has an interest. Although we expect Equity Residential to operate that partnership in compliance with the REIT requirements, because we do not expect to control the Equity Residential partnership in which the joint venture has an interest we cannot assure you that it will be operated in compliance with the REIT requirements, and failure to do so could potentially jeopardize our REIT status.

The ability of our stockholders to control our policies and effect a change of control of our company is limited by certain provisions of our charter and bylaws and by Maryland law.

        There are provisions in our charter and bylaws that may discourage a third party from making a proposal to acquire us, even if some of our stockholders might consider the proposal to be in their best interests. These provisions include the following:

        Our charter authorizes our Board of Directors to issue up to 50,000,000 shares of preferred stock without stockholder approval and to establish the preferences and rights, including voting rights, of any series of preferred stock issued. The Board of Directors may issue preferred stock without stockholder approval, which could allow the Board to issue one or more classes or series of preferred stock that could discourage or delay a tender offer or a change in control.

        To maintain our qualification as a REIT for federal income tax purposes, not more than 50% in value of our outstanding stock may be owned, directly or indirectly, by or for five or fewer individuals at any time during the last half of any taxable year. To maintain this qualification, and/or to address

24


Table of Contents

other concerns about concentrations of ownership of our stock, our charter generally prohibits ownership (directly, indirectly by virtue of the attribution provisions of the Code, or beneficially as defined in Section 13 of the Securities Exchange Act) by any single stockholder of more than 9.8% of the issued and outstanding shares of any class or series of our stock. In general, under our charter, pension plans and mutual funds may directly and beneficially own up to 15% of the outstanding shares of any class or series of stock. Under our charter, our Board of Directors may in its sole discretion waive or modify the ownership limit for one or more persons, but is not required to do so even if such waiver would not affect our qualification as a REIT. Our Board of Directors modified this ownership limit with respect to the common stock we expect to issue to Lehman for the Archstone Acquisition. These ownership limits may prevent or delay a change in control and, as a result, could adversely affect our stockholders' ability to realize a premium for their shares of common stock.

        As a Maryland corporation, we are subject to the provisions of the Maryland General Corporation Law. Maryland law imposes restrictions on some business combinations and requires compliance with statutory procedures before some mergers and acquisitions may occur, which may delay or prevent offers to acquire us or increase the difficulty of completing any offers, even if they are in our stockholders' best interests. In addition, other provisions of the Maryland General Corporation Law permit the Board of Directors to make elections and to take actions without stockholder approval (such as classifying our Board such that the entire Board is not up for re-election annually) that, if made or taken, could have the effect of discouraging or delaying a change in control.

ITEM 1b.    UNRESOLVED STAFF COMMENTS

        None.

ITEM 2.    COMMUNITIES

        Our real estate investments consist primarily of current operating apartment communities, communities in various stages of development ("Development Communities") and Development Rights (as defined below). Our current operating communities are further distinguished as Established Communities, Other Stabilized Communities, Lease-Up Communities and Redevelopment Communities. The following is a description of each category:

        Current Communities are categorized as Established, Other Stabilized, Lease-Up, or Redevelopment according to the following attributes:

    •
    Established Communities (also known as Same Store 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 occupancy and operating expenses as of the beginning of the prior year. For the year ended December 31, 2012, the Established Communities are communities that are consolidated for financial reporting purposes, had stabilized occupancy and operating expenses as of January 1, 2011, are not conducting or planning to conduct substantial redevelopment activities and are not held for sale or planned for disposition within the current year. A community is considered to have stabilized occupancy at the earlier of (i) attainment of 95% physical occupancy or (ii) the one-year anniversary of completion of development or redevelopment.

    •
    Other Stabilized Communities includes all other completed communities that we own or have a direct or indirect ownership interest in, and that have stabilized occupancy, as defined above. Other Stabilized Communities do not include communities that are conducting or planning to conduct substantial redevelopment activities within the current year.

    •
    Lease-Up Communities are communities where construction has been complete for less than one year and where physical occupancy has not reached 95%.

    •
    Redevelopment Communities are communities where substantial redevelopment is in progress or is planned to begin during the current year. For communities that we wholly own, 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 capitalized cost and is expected to have a material impact on the community's operations and future rental rates. The occupancy levels of Redevelopment Communities may also be impacted to the extent we take multiple apartment homes out of service for an extended period of time. The definition of substantial redevelopment may differ for communities owned through a joint venture arrangement or by one of the Funds.

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

        Development Rights are development opportunities in the early phase of the development process for which we either have an option to acquire land or enter into a leasehold interest, for which we are the buyer under a long-term conditional contract to purchase land or where we own land to develop a new community. We capitalize related pre-development costs incurred in pursuit of new developments for which we currently believe future development is probable.

Table of Contents

        As of December 31, 2012, communities that we owned or held a direct or indirect interest in were classified as follows. The information presented in this table may materially change as a result of the expected Archstone Acquisition which we anticipate will occur in the first quarter of 2013.

In addition to the four communities indicated, the Company commenced the redevelopment of two communities with an aggregate of 1,468 apartment homes during 2012, for which at December 31, 2012 the redevelopment activity is focused on the common areas and is not impacting community operations, including occupancy or rental revenue. These communities are therefore included in the Established Community portfolio.

        Our holdings under each of the above categories are discussed on the following pages.

        We generally establish the composition of our Established Communities portfolio annually. For the years ended December 31, 2012, 2011 and 2010, there were 11, 14 and 15 communities added, respectively to the Established Communities portfolio, and 17 communities removed in 2012, and seven communities removed in 2011 and 2010, from our Established Communities portfolio. We anticipate that we will reset the composition of our Established Community portfolio effective both January 1, 2014 and April 1, 2014. The expected reset of the Established Community portfolio on April 1, 2014 will occur as a result of the large number of stabilized communities we expect to acquire in the first quarter of 2013 as part of the Archstone Acquisition.

Current Communities

        Our Current Communities include garden-style apartment communities consisting of multi-story buildings in landscaped settings, as well as mid and high rise apartment communities in urban settings.

27


Table of Contents

As of January 31, 2013, our current communities consisted of 119 garden-style (of which 16 are mixed communities and/or include town homes), 22 high-rise and 37 mid-rise apartment communities.

        Our communities generally offer a variety of quality amenities and features, which may include:

    •
    fully-equipped kitchens;

    •
    lofts and vaulted ceilings;

    •
    walk-in closets;

    •
    fireplaces;

    •
    patios/decks; and

    •
    modern appliances.

        Other features at various communities may include:

    •
    swimming pools;

    •
    fitness centers;

    •
    tennis courts; and

    •
    wi-fi lounges.

        As described in Item 1, we operate under three core brands Avalon, AVA, and Eaves by Avalon. Our core Avalon brand focuses on upscale apartment living and high end amenities and services. "AVA" targets customers in high energy, transit-served urban neighborhoods and generally features smaller apartments, many of which are designed for roommate living with an emphasis on modern design and a technology focus. "Eaves by Avalon" is targeted to the cost conscious, "value" segment in suburban areas. We believe that these brands allow us to further penetrate our existing markets by targeting our market by consumer preference and attitude as well as by location and price.

        We also have an extensive and ongoing maintenance program to continually maintain and enhance our communities and apartment homes. The aesthetic appeal of our communities and a service-oriented property management team, focused on the specific needs of residents, enhances market appeal to discriminating residents. We believe our mission of Enhancing the Lives of our Residents helps us achieve higher rental rates and occupancy levels while minimizing resident turnover and operating expenses.

During the year ended December 31, 2012, we completed construction of 1,934 apartment homes in eight communities, and sold 1,578 apartment homes in four communities. The average age of our Current Communities, on a weighted average basis according to number of apartment homes, is 17.8 years. When adjusted to reflect redevelopment activity, as if redevelopment were a new construction completion date, the weighted average age of our Current Communities is 10.5 years.

        Of the Current Communities, as of January 31, 2013, we owned:

    •
    a full fee simple, or absolute, ownership interest in 151 operating communities, ten of which are on land subject to land leases expiring in October 2026, November 2028, December 2034, December 2061, September 2065, April 2095, September 2105, April 2105, May 2105 and March 2142;

    •
    a general partnership interest and an indirect limited partnership interest in both Fund I and Fund II. Subsidiaries of Fund I own a fee simple interest in ten operating communities, and subsidiaries of Fund II own a fee simple interest in 12 operating communities;

    •
    a general partnership interest in one partnership structured as a "DownREIT," as described more fully below, that owns one community; and

    •
    a membership interest in four limited liability companies, that each hold a fee simple interest in an operating community.

        For some communities, a land lease is used to support tax advantaged structures that ultimately allow us to purchase the land upon lease expiration. We have options to purchase the underlying land for the leases that expire in October 2026, November 2028, December 2034 and April 2095. We also hold, directly or through wholly-owned subsidiaries, the full fee simple ownership interest in 19 of the 23 Development Communities and a leasehold interest in four of the Development Communities with the land leases expiring in May 2041, July 2046, December 2086, and November 2106. Two of the four land leases (those expiring in 2046 and 2086) provide options for the Company to purchase the land at some point during the lease term.

        In our partnership structured as a DownREIT, one of our wholly-owned subsidiaries is the general partner, and there are limited partners whose interest in the partnership is represented by units of limited partnership interest. Limited partners are entitled to receive an initial distribution before any distribution is made to the general partner. Under the partnership agreement for the DownREIT, the distributions per unit paid to the holders of units of limited partnership interests are equal to our current common stock dividend amount. The holders of units of limited partnership interest have the right to present all or some of their units for redemption for a cash amount as determined by the partnership agreement and based on the fair value of our common stock. In lieu of a cash redemption by the partnership, we may elect to acquire any unit presented for redemption for one share of our common stock or for such cash amount. As of January 31, 2013, there were 7,500 DownREIT partnership units outstanding. The DownREIT partnership is consolidated for financial reporting purposes.

Development Communities

        As of December 31, 2012, we had 23 Development Communities under construction. We expect these Development Communities, when completed, to add a total of 6,599 apartment homes to our portfolio for a total capitalized cost, including land acquisition costs, of approximately $1,832,900,000. In addition, the land for four Development Communities that we control under long-term land lease agreements are subject to future minimum rental amounts of approximately $9,302,000 per year in the aggregate. You should carefully review Item 1a., "Risk Factors," for a discussion of the risks associated with development activity and our discussion under Item 7., "Management's Discussion and Analysis of Financial Condition and Results of Operations," for further discussion of development activity.

        The following table presents a summary of the Development Communities. We hold a direct or indirect fee simple ownership interest in these communities except where noted. The information presented in this table may materially change as a result of the expected Archstone Acquisition which we anticipate will occur in the first quarter of 2013.

Total projected capitalized cost includes all capitalized costs projected to be or actually incurred to develop the respective Development Community, determined in accordance with GAAP, including land acquisition costs or land lease costs through construction completion, construction costs, real estate taxes, capitalized interest and loan fees, permits, professional fees, allocated development overhead and other regulatory fees. Total capitalized cost for communities identified as having joint venture ownership, either during construction or upon construction completion, represents the total projected joint venture contribution amount.

Redevelopment Communities

        As of December 31, 2012, we had five consolidated communities under redevelopment. We expect the total capitalized cost to redevelop these communities to be $59,800,000, excluding costs incurred prior to redevelopment. We have found that the cost to redevelop an existing apartment community is more difficult to budget and estimate than the cost to develop a new community. Accordingly, for redevelopment communities we expect that actual costs may vary from our budget by a wider range than for a new development community. We cannot assure you that we will meet our schedule for reconstruction completion or restabilized operations, or that we will meet our budgeted costs, either individually or in the aggregate. We anticipate continuing our current level of redevelopment activity related to communities in our current operating portfolio. You should carefully review Item 1a., "Risk Factors," for a discussion of the risks associated with redevelopment activity.

        The following presents a summary of these Redevelopment Communities. The information presented in this table may materially change as a result of the expected Archstone Acquisition which we anticipate will occur in the first quarter of 2013.

Development Rights

        At December 31, 2012, we had $316,037,000 in acquisition and related capitalized costs for land parcels we own, and $24,665,000 in capitalized costs (including legal fees, design fees and related overhead costs) related to Development Rights for which we control the land parcel, typically through an option to purchase or lease the land. Collectively, the land held for development and associated costs for deferred development rights relate to 34 Development Rights for which we expect to develop new apartment communities in the future. The cumulative capitalized costs for land held for development as of December 31, 2012 includes $244,015,000 in original land acquisition costs. The original land acquisition cost per home ranged from $9,000 per home in Connecticut to $149,000 per home in New York City. The Development Rights range from those beginning design and architectural planning to those that have completed site plans and drawings and can begin construction almost immediately. We estimate that the successful completion of all of these communities would ultimately add approximately 9,602 apartment homes to our portfolio. Substantially all of these apartment homes will offer features like those offered by the communities we currently own of the same brand group.

        For 21 Development Rights, we control the land through an option to purchase or lease the parcel. While we generally prefer to hold Development Rights through options to acquire land, for the 13 remaining Development Rights we either currently own the land or have executed a long term land lease for the parcel of land on which a community would be built if we proceeded with development.

        The properties comprising the Development Rights are in different stages of the due diligence and regulatory approval process. The decisions regarding the initial selection of a Development Right, and whether or not to continue to invest in a Development Right, are business judgments that we make after we perform financial, demographic and other analyses. In the event that we do not proceed with a Development Right, we generally would not recover capitalized costs incurred in the pursuit of those communities, unless we were to recover amounts in connection with the sale of land; however, we cannot guarantee a recovery. Initial development costs incurred for pursuits for which future development is not yet considered probable are expensed as incurred. In addition, if the status of a Development Right changes, making future development no longer probable, any capitalized pre-development costs are charged to expense. During 2012, we incurred a charge of approximately $1,757,000 for development pursuits that were not yet probable of future development at the time incurred, or for pursuits that we determined would not likely be developed.

        You should carefully review Section 1a., "Risk Factors," for a discussion of the risks associated with Development Rights.

Land Acquisitions

        We select land for development and follow established procedures that we believe minimize both the cost and the risks of development. During 2012, we acquired land parcels for nine Development Rights including the final land parcels related to our purchase commitment for Avalon Willoughby Square, as shown in the table below, for an aggregate purchase price of approximately $100,564,000. For eight of the nine parcels construction has either started or will start within the next 12 months. The information presented in this table may materially change as a result of the expected Archstone Acquisition which we anticipate will occur in the first quarter of 2013.

Other Land and Real Estate Assets

        We own land parcels with a carrying value of approximately $23,964,000 that we do not currently plan to develop. These parcels consist of land that we (i) originally planned to develop and (ii) ancillary parcels acquired in connection with Development Rights that we had not planned to develop. The current carrying value of these land parcels reflects impairment charges of $9,057,000 incurred in prior periods. We believe that the current carrying value for all of these land parcels is such that there is no indication of impaired value, or further need to record a charge for impairment in the case of assets previously impaired. However, we may be subject to the recognition of further charges for impairment

43


Table of Contents

in the event that there are indicators of such impairment and we determine that the carrying value of the assets is greater than the current fair value, less costs to dispose.

Recent Disposition Activity

        We (i) sell assets when they do not meet our long-term investment strategy or when capital and real estate markets allow us to realize a portion of the value created over the past business cycle and (ii) redeploy the proceeds from those sales to develop, redevelop and acquire communities. Pending such redeployment, we will generally use the proceeds from the sale of these communities to reduce amounts outstanding under our Credit Facility or retain the cash proceeds on our balance sheet until it is redeployed into development or redevelopment activity. On occasion, we will set aside the proceeds from the sale of communities into a cash escrow account to facilitate a tax deferred, like-kind exchange transaction. From January 1, 2012 to January 31, 2013, we sold our interest in four wholly-owned communities containing 1,578 apartment homes. The aggregate gross sales price for these assets was $268,250,000.

Insurance and Risk of Uninsured Losses

        We carry commercial general liability insurance and property insurance with respect to all of our communities. These policies, and other insurance policies we carry, have policy specifications, insured limits and deductibles that we consider commercially reasonable. There are, however, certain types of losses (such as losses arising from acts of war) that are not insured, in full or in part, because they are either uninsurable or the cost of insurance makes it, in management's view, economically impractical. You should carefully review the discussion under Item 1a., "Risk Factors," of this Form 10-K for a discussion of risks associated with an uninsured property or liability loss.

        Many of our West Coast communities are located in the general vicinity of active earthquake faults. Many of our communities are near, and thus susceptible to, the major fault lines in California, including the San Andreas Fault and the Hayward Fault. We cannot assure you that an earthquake would not cause damage or losses greater than insured levels. We have in place with respect to communities located in California and Washington, for any single occurrence and in the aggregate, $75,000,000 of coverage. Earthquake coverage outside of California and Washington is subject to a $100,000,000 limit for each occurrence and in the aggregate. In California the deductible for each occurrence is five percent of the insured value of each damaged building. Our earthquake insurance outside of California provides for a $100,000 deductible per occurrence except that the next $350,000 of loss per occurrence outside California will be treated as an additional self-insured retention until the total incurred self-insured retention exceeds $1,400,000.

        In May 2012, we renewed our property insurance policy, with no material change in coverage. In August 2012, we renewed our general liability and workers compensation insurance policies with no material change in coverage.

        In October 2012, Superstorm Sandy impacted several apartment communities in the Company's Mid-Atlantic and Northeast portfolios. The Company recognized a casualty loss of $1,449,000 for losses incurred related to Superstorm Sandy. As of the date of this filing, the Company does not expect to recognize significant additional costs related to the damage from Superstorm Sandy.

        Just as with office buildings, transportation systems and government buildings, there have been reports that apartment communities could become targets of terrorism. In December 2007, Congress passed the Terrorism Risk Insurance Program Reauthorization Act ("TRIPRA") which is designed to make terrorism insurance available through a federal back-stop program until 2014. In connection with this legislation, we have purchased insurance for property damage due to terrorism up to $250,000,000. Additionally, we have purchased insurance for certain terrorist acts, not covered under TRIPRA, such as domestic-based terrorism. This insurance, often referred to as "non-certified" terrorism insurance, is

44


Table of Contents

subject to deductibles, limits and exclusions. Our general liability policy provides TRIPRA coverage (subject to deductibles and insured limits) for liability to third parties that result from terrorist acts at our communities.

        An additional consideration for insurance coverage and potential uninsured losses is mold growth. Mold growth may occur when excessive moisture accumulates in buildings or on building materials, particularly if the moisture problem remains undiscovered or is not addressed over a period of time. If a significant mold problem arises at one of our communities, we could be required to undertake a costly remediation program to contain or remove the mold from the affected community and could be exposed to other liabilities. For further discussion of the risks and the Company's related prevention and remediation activities, please refer to the discussion under Item 1a., "Risk Factors—We may incur costs due to environmental contamination or non-compliance," elsewhere in this report. We cannot provide assurance that we will have coverage under our existing policies for property damage or liability to third parties arising as a result of exposure to mold or a claim of exposure to mold at one of our communities.

        We also carry crime policies (also commonly referred to as a fidelity policy or employee dishonesty policy) that protect the Company, up to $5,000,000 per occurrence, from employee theft of money, securities or property.

ITEM 3.    LEGAL PROCEEDINGS

        The Company is involved in various claims and/or administrative proceedings that arise in the ordinary course of our business. While no assurances can be given, the Company does not currently believe that any of these outstanding litigation matters, individually or in the aggregate, will have a material adverse effect on its financial condition or results of operations.

        At present, we expect to continue our policy of paying regular quarterly cash dividends. However, the form, timing and/or amount of dividend distributions will be declared at the discretion of the Board of Directors and will depend on actual cash from operations, our financial condition, capital requirements, the annual distribution requirements under the REIT provisions of the Internal Revenue Code and other factors as the Board of Directors may consider relevant. The Board of Directors may modify our dividend policy from time to time.

        In January 2013, we announced that our Board of Directors declared a dividend on our common stock for the first quarter of 2013 of $1.07 per share, a 10.3% increase over the previous quarterly dividend per share of $0.97. The dividend will be payable on April 15, 2013 to all common stockholders of record as of March 28, 2013.

Notes
to Selected Financial Data 
(1)
Interest expense, net includes any loss or gain incurred from the extinguishment of debt.

(2)
EBITDA is defined as net income before interest income and expense, income taxes, depreciation and amortization from both continuing and discontinued operations. Under this definition, EBITDA includes gains on sale of assets and gain on sale of partnership interests. Management generally considers EBITDA to be an appropriate supplemental measure to net income of our operating performance because it helps investors to understand our ability to incur and service debt and to make capital expenditures. EBITDA should not be considered as an alternative to net income (as determined in accordance with GAAP), as an indicator of our operating performance, or to cash flows from operating activities (as determined in accordance with GAAP) as a measure of liquidity. Our calculation of EBITDA may not be comparable to EBITDA as calculated by other companies.

(3)
We generally consider Funds from Operations, or "FFO," as defined below, to be an appropriate supplemental measure of our operating and financial performance because, by excluding gains or losses related to dispositions of previously depreciated property 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 real estate company between periods or as compared to different companies. We believe that in order to understand our operating results, FFO should be examined with net income as presented in the Consolidated Statements of Comprehensive Income included elsewhere in this report.


Consistent with the definition adopted by the Board of Governors of the National Association of Real Estate Investment Trusts® ("NAREIT"), we calculate FFO as net income or loss computed in accordance with GAAP, adjusted for:

    •
    gains or losses on sales of previously depreciated operating communities;

    •
    extraordinary gains or losses (as defined by GAAP);

    •
    cumulative effect of change in accounting principle;

    •
    impairment write-downs of depreciable real estate assets;

    •
    write-downs of investments in affiliates due to a decrease in the value of depreciable real estate assets held by those affiliates;

    •
    depreciation of real estate assets; and

    •
    adjustments for unconsolidated partnerships and joint ventures.

FFO does not represent net income in accordance with GAAP, and therefore it should not be considered an alternative to net income, which remains the primary measure, as an indication of our performance. In addition, FFO as calculated by other REITs may not be comparable to our calculation of FFO.


FFO also does not represent cash generated from operating activities in accordance with GAAP, and therefore should not be considered an alternative to net cash flows from operating activities, as determined by GAAP, as a measure of liquidity. Additionally, it is not necessarily indicative of cash available to fund cash needs. A presentation of GAAP based cash flow metrics is provided in "Cash Flow Information" in the table on the previous page.


The following is a reconciliation of net income to FFO (dollars in thousands, except per share data).

ITEM 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

        Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") is intended to help provide an understanding of our business and results of operations. This MD&A should be read in conjunction with our Consolidated Financial Statements and the accompanying Notes to Consolidated Financial Statements included elsewhere in this report. This report, including the following MD&A, contains forward-looking statements regarding future events or trends that should be read in conjunction with the factors described under "Forward-Looking Statements" included in this report. In addition, our actual results or developments could differ materially from those projected in such forward-looking statements as a result of the factors discussed under "Forward-Looking Statements" as well as the risk factors described in Item 1a, "Risk Factors," of this report.

        Capitalized terms used without definitions have the meaning as provided elsewhere in this Form 10-K.

Executive Overview

        As discussed under Item 1., "Business," we executed the Purchase Agreement under which we expect to acquire direct and indirect interests in certain operating and development communities from Archstone. We expect this transaction will close in the first quarter of 2013. The impact of the Archstone Acquisition is expected to significantly change the scope of our business and as a result our 2012 results of operations may not necessarily be representative of our future results of operations. Unless otherwise stated, all disclosures and discussion in this Form 10-K do not include the expected effects of the Archstone Acquisition.

Business Description

        We are primarily engaged in developing, acquiring, owning and operating apartment communities in high barrier to entry markets of the United States. We believe that apartment communities are an attractive long-term investment opportunity compared to other real estate investments, because a broad potential resident base should help reduce demand volatility over a real estate cycle. However, throughout the real estate cycle, apartment market fundamentals, and therefore operating cash flows, are affected by overall economic conditions. We seek to create long-term shareholder value by accessing capital on cost effective terms; deploying that capital to develop, redevelop and acquire apartment communities in high barrier to entry markets; operating apartment communities; and selling communities when pricing is attractive or when they no longer meet our long-term investment strategy. Barriers to entry in our markets generally include a difficult and lengthy entitlement process with local jurisdictions and dense urban or suburban areas where zoned and entitled land is in limited supply.

        Our strategy is to be a leader in multifamily market research, consumer insight, and capital allocation, delivering a range of multifamily offerings tailored to serve the needs of the most attractive customer segments in the best-performing submarkets of the United States. Our communities are predominately upscale, which generally command among the highest rents in their markets. We also pursue the ownership and operation of apartment communities that target a variety of customer segments and price points, consistent with our goal of offering a broad range of products and services.

        We regularly evaluate the allocation of our investments by the amount of invested capital and by product type within our markets. Our current markets include New England, the New York/New Jersey metro area, the Mid-Atlantic, the Pacific Northwest, and the Northern and Southern California regions of the United States.

Financial Highlights

        For the year ended December 31, 2012, net income attributable to common stockholders was $423,869,000 compared to $441,622,000 for 2011, a decrease of 4.0%. The decrease was due primarily to decreased gains on sale of communities in 2012 as compared to 2011 and acquisition costs for the expected Archstone Acquisition offset partially by an increase in net operating income ("NOI") from both Established and newly stabilized communities.

        Apartment fundamentals improved throughout 2012 as compared to 2011, driven by a combination of a decline in the home ownership rate, modest employment growth and limited supply of new multifamily rental product. Full year 2012 Established Communities NOI increased 7.6% over the prior year across all of our markets as a result of an increase in rental revenue offset partially by an increase in operating expenses.

        During 2012, we raised approximately $3,370,000,000 of capital through the issuance of common equity and unsecured notes and asset sales. Proceeds were used to prefund our expected portion of the acquisition of Archstone, to fund current investment activities and to repay higher cost secured and unsecured debt both at or prior to their stated maturity. We believe that our current capital structure will continue to provide financial flexibility to access capital on attractive terms. The funds raised from dispositions consist of the proceeds from the sale of four communities and one land parcel for a gross sales price of $280,550,000.

        We believe our development activity will continue to create long-term value. We increased development activity during 2012 from the prior year in anticipation of favorable economic conditions and apartment fundamentals. During 2012, we completed the development of eight communities for an aggregate total capitalized cost of $513,100,000. We also started the development of twelve communities, which are expected to be completed for an estimated total capitalized cost of $891,300,000. In addition, during 2012 we completed the redevelopment of eleven communities for a total investment of $105,900,000, excluding costs incurred prior to the redevelopment.

        We believe that our current level of indebtedness, our current ability to service interest and other fixed charges and our current limited use of financial encumbrances (such as secured financing) provides flexibility in our capital raising activities. We expect to meet our liquidity needs from the issuance of unsecured debt and/or common and preferred equity and/or secured debt, as well as from disposition proceeds, joint venture investments or from retained cash. These sources will provide adequate access to the capital necessary to fund our development and redevelopment activities during 2013.

        With the completion of the investment period for Fund II in 2011, we became active again in acquiring wholly-owned apartment communities, directly purchasing the following four apartment communities during 2012, one of which occurred through a purchase of our joint venture partner's interest.

    •
    The Mark Pasadena, located in Pasadena, CA, which contains 84 apartment homes, was acquired for a purchase price of $19,400,000. In conjunction with this acquisition, we assumed the existing 4.61% fixed-rate mortgage loan with an outstanding principal amount of $11,958,000 which matures in June 2018 and is secured by the community.

    •
    Eaves Cerritos, located in Artesia, CA, which contains 151 apartment homes, was acquired for a purchase price of $29,500,000.

    •
    Eaves Burlington, located in Burlington MA, which contains 203 homes, was acquired for a purchase price of $40,250,000.

    •
    The Company acquired Avalon Del Rey, a 309 apartment home community which was owned by a joint venture in which we held a 30% ownership interest. As part of this transaction, the

51


Table of Contents

      venture repaid the $43,606,000 variable rate note secured by the community. We paid approximately $67,200,000 for the joint venture partner's 70% interest as well as contributing our proportionate share of the note repayment to the venture. Upon the acquisition of Avalon Del Rey, we consolidated the community.

        We established Fund I and Fund II to engage in acquisition programs through discretionary investment funds. We believe this investment format provides the following attributes: (i) it enables us to access third-party joint venture equity as an additional source of financing to expand and diversify our portfolio; (ii) it provides us with additional sources of income in the form of property management and asset management fees and, potentially, incentive distributions if the performance of the Funds exceeds certain thresholds; and (iii) it gives us greater visibility into the transactions occurring in multifamily assets, which helps us with other investment decisions related to our wholly-owned portfolio.

        Fund I has nine institutional investors, including us. One of our wholly-owned subsidiaries is the general partner of Fund I and, excluding costs incurred in excess of our equity in the underlying net assets of Fund I, we have made an equity investment of approximately $21,100,000 in Fund I (net of distributions and excluding the purchase by us of a mortgage note secured by a Fund I community), representing a 15.15% combined general partner and limited partner equity interest. Fund I was our principal vehicle for acquiring apartment communities from its formation in 2005 through the close of its investment period in March 2008. Fund I has a term that expires in March 2013, plus two one-year extension options.

        During 2012, Fund I sold six communities:

    •
    Avalon Lakeside, a 204 apartment home community in Chicago, IL, for $20,500,000;

    •
    Avalon at Poplar Creek, a 196 apartment home community in Chicago, IL, for $27,200,000;

    •
    Avalon Lombard, a 256 apartment home community in Chicago, IL, for $35,450,000;

    •
    Avalon Paseo Place, a 134 apartment home community in Fremont, CA, for $30,900,000;

    •
    Avalon Skyway, a 348 apartment home community in San Jose, CA, for $90,900,000; and

    •
    Avalon at Aberdeen Station, a 290 apartment home community in Aberdeen, NJ, for $66,250,000.

        Our proportionate share of the gain from the sale of these communities was $7,971,000. In conjunction with the disposition of these communities, Fund I repaid $89,142,000 of the related secured indebtedness in advance of the scheduled maturity dates, incurring charges for prepayment penalties and write off of deferred financing costs, of which our portion was approximately $530,000, reported as a reduction of Equity in income of unconsolidated entities.

        In addition, in 2013, Fund I sold Avalon at Yerba Buena, located in San Francisco, CA. Avalon at Yerba Buena contains 160 apartment homes and 32,000 square feet of retail space and was sold for $103,000,000.

        Fund II has six institutional investors, including us. One of our wholly owned subsidiaries is the general partner of Fund II and excluding costs incurred in excess of our equity in the underlying net assets of Fund II, we have made an equity investment of $107,938,000 (net of distributions), representing a 31.3% combined general partner and limited partner equity interest. Fund II served as the exclusive vehicle through which we acquired investment interests in apartment communities from its formation in 2008 through the close of its investment period in August 2011.

Table of Contents

        During the year ended December 31, 2012, a subsidiary of Fund II acquired Avalon Watchung, a 334 apartment home community located in Watchung, NJ, for $63,000,000. This was the final acquisition for Fund II.

        In 2013, Fund II sold Avalon Rothbury, a 205 apartment home community located in Gaithersburg, MD, for $39,600,000.

        We are not presently pursuing the formation of a new, third fund, preferring at this time to maintain flexibility in shaping our portfolio of wholly-owned assets through acquisitions and dispositions. However, we may acquire investments in existing fund structures in connection with the Archstone Acquisition, but these funds are not expected to limit our ability to acquire investments for our own account.

Communities Overview

        As of December 31, 2012, we owned or held a direct or indirect ownership interest in 203 apartment communities containing 59,391 apartment homes in nine states and the District of Columbia, of which 23 communities were under construction and five communities were under reconstruction. Of these communities, 26 were owned by entities that were not consolidated for financial reporting purposes, including 11 owned by subsidiaries of Fund I and 13 owned by subsidiaries of Fund II. In addition, we owned a direct or indirect ownership interest in Development Rights to develop an additional 34 wholly-owned communities that, if developed in the manner expected, will contain an estimated 9,602 apartment homes.

        Our real estate investments consist primarily of current operating apartment communities, Development Communities, and Development Rights. Our current operating communities are further distinguished as Established Communities, Other Stabilized Communities, Lease-Up Communities and Redevelopment Communities. Established Communities are generally operating communities that are consolidated for financial reporting purposes and were owned and had stabilized occupancy and operating expenses as of the beginning of the prior year, which allows the performance of these communities and the markets in which they are located to be compared between years. Other Stabilized Communities are generally all other consolidated operating communities that have stabilized occupancy and operating expenses during the current year, but had not achieved stabilization as of the beginning of the prior year. Lease-Up Communities consist of communities where construction is complete but stabilization has not been achieved. Redevelopment Communities consist of communities where substantial redevelopment is in progress or is planned to begin during the current year. A more detailed description of our reportable segments and other related operating information can be found in Note 8, "Segment Reporting," of our Consolidated Financial Statements.

        Although each of these categories is important to our business, we generally evaluate overall operating, industry and market trends based on the operating results of Established Communities, for which a detailed discussion can be found in "Results of Operations" as part of our discussion of overall operating results. We evaluate our current and future cash needs and future operating potential based on acquisition, disposition, development, redevelopment and financing activities within Other Stabilized, Redevelopment and Development Communities. Discussions related to these segments of our business can be found in "Liquidity and Capital Resources."

        NOI of our current operating communities is one of the financial measures that we use to evaluate community performance. NOI is affected by the demand and supply dynamics within our markets, our rental rates and occupancy levels and our ability to control operating costs. Our overall financial performance is also impacted by the general availability and cost of capital and the performance of newly developed and acquired apartment communities.

Results of Operations

        Our year-over-year operating performance is primarily affected by both overall and individual geographic market conditions and apartment fundamentals and reflected in changes in NOI of our Established Communities; NOI derived from acquisitions and development completions; the loss of NOI related to disposed communities; and capital market and financing activity.

        Net income attributable to common stockholders decreased $17,753,000, or 4.0%, to $423,869,000 in 2012 primarily due to a decrease in gain on sale of communities as compared to the prior year, offset partially by increased NOI in 2012 over 2011. Net income attributable to common stockholders increased $266,291,000, or 151.9% in 2011 over 2010 due primarily to an increase in gain on sale of communities and increased NOI in 2011 over 2010.

        NOI is considered by management to be an important and appropriate supplemental performance measure to net income 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 or financing-related costs. NOI reflects the operating performance of a community and allows for an easy

Table of Contents

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 impacts 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 group of assets. We define NOI as total property revenue less direct property operating expenses, including property taxes.

        NOI does not represent cash generated from operating activities in accordance with GAAP. Therefore, NOI should not be considered an alternative to net income as an indication of our performance. NOI should also not be considered an alternative to net cash flow from operating activities, as determined by GAAP, as a measure of liquidity, nor is NOI necessarily indicative of cash available to fund cash needs. Reconciliations of NOI for the years ended December 31, 2012, 2011 and 2010 to net income for each year are as follows (dollars in thousands):

        The NOI increase for Established Communities in 2012 is due to a combination of increased rental revenues, offset partially by increased operating expenses. During 2012, we experienced sequential annual increases in rental rates over 2011, while maintaining occupancy of at least 95% in all markets, offset partially by an increase in operating expenses.

        Rental and other income increased in both 2012 and 2011 as compared to the prior years due to additional rental income generated from newly developed and acquired communities and increases in rental rates at our Established Communities.

            Overall Portfolio—The weighted average number of occupied apartment homes increased to 43,411 apartment homes for 2012 as compared to 42,613 homes for 2011 and 40,489 homes for 2010. The increase in 2012 over 2011 is due to homes available from newly developed and acquired communities, offset partially by communities sold during 2012 and 2011. The weighted

55


Table of Contents

    average monthly revenue per occupied apartment home increased to $2,017 for 2012 as compared to $1,911 in 2011 and $1,823 in 2010.

            Established Communities—Rental revenue increased $41,698,000, or 5.8%, for 2012 and increased $33,335,000 or 5.1%, for 2011 as compared to the respective prior years. For 2012, the weighted average monthly revenue per occupied apartment home increased 5.6% to $2,092 compared to $1,981 in 2011 coupled with an increase in economic occupancy of 0.2% to 96.1%. 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. Economic occupancy is defined as gross potential revenue less vacancy loss, as a percentage of gross potential revenue. Gross potential revenue is determined by valuing occupied homes at leased rates and vacant homes at market rents.

            We experienced increases in rental revenue for all of our Established Communities regions in 2012 as compared to the prior year as discussed in more detail below.

            The Metro New York/New Jersey region, which accounted for approximately 30.1% of Established Community rental revenue for 2012, experienced an increase in rental revenue of 5.5% for 2012 as compared to 2011. Average rental rates increased 5.2% to $2,548 over 2011 and economic occupancy increased 0.3% to 96.4% for 2012 as compared to 2011. While there has not been significant job growth in the financial services sector of the Metro New York/New Jersey region, job growth in the technology sector continues to support the improvement in apartment fundamentals in New York City and Northern New Jersey.

            The New England region accounted for approximately 22.0% of the Established Community rental revenue for 2012 and experienced a rental revenue increase of 4.2% over the prior year. Average rental rates increased 4.6% to $2,073, offset partially by a decrease in economic occupancy of 0.4% to 95.7% for 2012 as compared to 2011. The New England region's growth is driven by a renewed expansion in employment for the technology sector, primarily in the greater Boston area, offset somewhat by weakness in the financial services sector impacting the Fairfield-New Haven area. We expect continued but moderating revenue growth, with the increasing affordability of home ownership and future supply from new development impacting the longer term outlook.

            Northern California accounted for approximately 17.0% of the Established Community rental revenue for 2012 and experienced a rental revenue increase of 10.1% over the prior year. Average rental rates increased 10.0% to $2,151, and economic occupancy increased 0.1% to 96.1% for 2012 as compared to 2011. The growth in rental revenue is driven by the strength of Northern California's technology sector, which we expect will continue in 2013. An increase in development activity and future supply may slow revenue growth in future periods.

            The Mid-Atlantic region, which represented approximately 13.6% of Established Community rental revenue during 2012, experienced an increase in rental revenue of 3.6% as compared to 2011. Average rental rates increased by 3.2% to $1,900, and economic occupancy increased 0.4% to 95.9% for 2012 as compared to 2011. The Mid-Atlantic region is facing challenges resulting from additional supply due to new development and the uncertainty surrounding federal spending. We expect these factors will result in revenue growth at a slower pace relative to our other markets during 2013.

            Southern California accounted for approximately 13.0% of the Established Community rental revenue for 2012 and experienced a rental revenue increase of 4.9% over the prior year. Average rental rates increased 4.5% to $1,753, and economic occupancy increased 0.4% to 96.3% for 2012 as compared to 2011. The improvement in the Southern California market is driven by above average job growth and limited new supply, and we expect this trend will continue into 2013.

            The Pacific Northwest region accounted for approximately 4.3% of the Established Community rental revenue for 2012 and experienced a rental revenue increase of 9.6% over the prior year. Average rental rates increased 8.3% to $1,493, and economic occupancy increased by 1.3% to 96.3% for 2012 as compared to 2011. The Pacific Northwest's retail, technology and manufacturing sectors continue to support job creation and apartment fundamentals. Consistent with several of our other markets, new development and resulting additional supply may moderate revenue growth in future periods.

        Management, development and other fees increased $601,000, or 6.2%, in 2012 over 2011 and $2,302,000, or 31.3% in 2011 over 2010. The increases in both years were due primarily to increased asset management fees and property management fees from Fund II over the prior years.

        Direct property operating expenses, excluding property taxes increased $9,455,000, or 4.5% in 2012 and increased $7,007,000, or 3.5% for 2011 as compared to the prior years, primarily due to the addition of recently developed apartment homes.

        For Established Communities, direct property operating expenses, excluding property taxes, decreased $475,000, or 0.3% for 2012 and decreased $2,514,000 or 1.6% for 2011 as compared to the prior years. The decreases in 2012 and 2011 from the respective prior years were due to a decrease in utilities from milder temperatures and more favorable negotiated rates as well as decreased bad debt expense.

        Property taxes increased $8,568,000, or 9.3% and $4,704,000, or 5.4% in 2012 and 2011, respectively, over the prior years due to the addition of newly developed and redeveloped apartment homes and overall higher assessments. Property tax increases are also impacted by the size and timing of successful tax appeals.

        For Established Communities, property taxes increased by $4,581,000, or 6.5% and decreased $631,000, or 0.9%, for 2012 and 2011, respectively, as compared to the prior year. The increase in 2012 over 2011 is due to appeals and settlements recognized in 2011 not present in 2012 coupled with increases in rates and assessments throughout our regions. The decrease in 2011 from 2010 is due to the appeals and settlements recognized in 2011 not present in 2010, offset partially by increased rates and assessments across all of our regions.

        Corporate-level property management and other indirect operating expenses increased by $1,980,000, or 4.9% and $2,926,000, or 7.8% in 2012 and 2011, respectively, over the prior years. The increases in 2012 and 2011 from the prior years are due primarily to increases in costs associated with our introduction and implementation of our AVA and Eaves by Avalon brands, and increases in compensation costs.

        Investments and investment management costs increased by $945,000, or 18.4% and $1,302,000, or 34.0% in 2012 and 2011, respectively, over the prior years due primarily to increases in compensation costs.

        Expensed acquisition, development and other pursuit costs primarily reflect the costs incurred for acquisitions of operating real estate and abandoned pursuit costs, which include costs incurred for development pursuits not yet considered probable for development, as well as the abandonment of Development Rights and disposition pursuits. These costs can be volatile, particularly in periods of increased acquisition activity, periods of economic downturn or when there is limited access to capital, and the costs may vary significantly from period to period. These costs increased $8,383,000 or 282.5% in 2012 over 2011 due primarily to costs associated with the Archstone Acquisition.

        Interest expense, net decreased $30,894,000, or 18.4% and decreased $2,183,000, or 1.3% in 2012 and 2011, respectively as compared to the prior years. The decreases in 2012 and 2011 from the prior years are due primarily to decreases in the average outstanding indebtedness and lower average effective interest rates coupled with increases in the amount of capitalized interest. The increases in capitalized interest over the respective prior years were driven primarily by the increase in our development activity and development pursuits. The year-over-year decrease in interest expense, net, in 2012 from 2011 was offset somewhat by interest income associated with escrow accounts for certain tax exempt secured borrowings recognized in 2011 that were not present in 2012.

        Loss on the extinguishment of debt, net reflects the impact from prepayment penalties, expensing deferred financing costs from our debt repurchase and retirement activity, or payments above or below

the carrying basis, excluding assets sold or held for sale, which is included in discontinued operations, below. During 2012, we recognized a non-cash charge for the write off of deferred financing fees related to the early retirement of a secured note. In 2011 we incurred charges for a prepayment penalty and the write off of deferred financing fees related to the early retirement of a secured note, with no comparable activity in 2010.

        Depreciation expense increased in 2012 and 2011 primarily due to the net increase in assets from the completion of development and redevelopment activities and acquisition activity, offset by a reduction in depreciation expense from assets sold during 2012, 2011and 2010.

        General and administrative expense ("G&A") increased $4,730,000, or 16.1% in 2012 and $2,525,000, or 9.4% in 2011 as compared to the prior years. The increases in both periods are attributable to increased compensation expense and professional fees.

        Casualty and impairment loss for 2012 consists of the losses we incurred associated with Superstorm Sandy. Amounts for 2011 are composed of the write down of two land parcels and an other than temporary impairment of an investment in unconsolidated joint venture.

        Gain on sale of land decreased in 2012 and increased in 2011 as compared to the prior years due to the volume and associated gains on the sale of land parcels in each of the respective years.

        Gain on acquisition of unconsolidated entity represents the amount by which the fair value of our prior ownership interest in the joint venture that owned Avalon Del Rey exceeded our carrying value.

        Equity in income of unconsolidated entities increased $15,794,000, or 308.5% in 2012 and $4,358,000, or 571.9% in 2011 as compared to prior years. The increase in 2012 is due primarily to the recognition of income from our promoted interest for Avalon Del Rey and an increase in our proportionate share of gains from Fund I disposition activity over the prior year periods. The increase in 2011 is due to the recognition of our proportionate share of the gain on sale of communities by Fund I, offset partially by increased acquisition costs from Fund II over 2010.

        Income from discontinued operations represents the net income generated by communities sold or qualifying as discontinued operations during the period from January 1, 2010 through December 31, 2012. This income increased for 2012 and decreased for 2011 due to changes in the number of communities sold in each year as compared to the prior year period. See Note 6, "Real Estate Disposition Activities," to our Consolidated Financial Statements.

        Gain on sale of communities decreased in 2012 and increased in 2011 as compared to the prior years due to a change in the volume of community disposition activity and associated gains as compared to the prior year. The amount of gain realized upon disposition of a community depends on many factors, including the number of communities sold, the size and carrying value of those communities and the market conditions in the local area.

        Net loss attributable to noncontrolling interests resulted in income to us from the allocation of losses to the noncontrolling interests of $307,000 in 2012 and $252,000 in 2011. The decrease in loss allocated in 2011 relative to 2010 is due primarily to improved operating results of the Fund I community we consolidate. The conversion and redemption of limited partnership units in 2011 and 2010 also contributed to the decrease in 2011 from 2010, thereby reducing outside ownership interest and the allocation of net losses to outside ownership interests.

Liquidity and Capital Resources

        We believe our principal short-term liquidity needs are to fund:

    •
    the cash consideration due and any costs associated with the expected Archstone Acquisition as discussed in this Form 10-K, or any additional liquidity needs associated with the expected Archstone Acquisition;

    •
    development and redevelopment activity in which we are currently engaged;

    •
    the minimum dividend payments on our common stock required to maintain our REIT qualification under the Code;

    •
    debt service and principal payments either at maturity or opportunistically prior to maturity; and

    •
    normal recurring operating expenses.

        Factors affecting our liquidity and capital resources are our cash flows from operations, financing activities and investing activities (including dispositions) as well as general economic and market conditions. Operating cash flow has historically been determined by: (i) the number of apartment homes currently owned, (ii) rental rates, (iii) occupancy levels and (iv) operating expenses with respect to apartment homes. The timing and type of capital markets activity in which we engage, as well as our plans for development, redevelopment, acquisition and disposition activity, are affected by changes in the capital markets environment, such as changes in interest rates or the availability of cost-effective capital. We regularly review our liquidity needs, the adequacy of cash flows from operations and other expected liquidity sources to meet these needs.

        We continued to have cost effective access to the capital markets during the year ended December 31, 2012. Net proceeds of approximately $3,100,458,000 were provided by capital markets activity in 2012. Capital raising activities included public equity and debt, including amounts issued in an underwritten public offering of common stock in December 2012, the issuance of unsecured notes in September and December 2012 and the issuance of common stock during 2012 under CEP II and CEP III, discussed below. In 2013, we expect to meet all of our liquidity needs from a variety of internal and external sources, including cash balances on hand, asset sales and other public or private sources of liquidity as discussed below, as well as our operating activities. Our ability to obtain additional financing will depend on a variety of factors such as market conditions, the general availability of credit, the overall availability of credit to the real estate industry, our credit ratings and credit capacity, as well as the perception of lenders regarding our long or short-term financial prospects. At December 31, 2012, we have unrestricted cash and cash equivalents of $2,733,618,000 available to fund the Archstone Acquisition, to fund current liquidity needs as well as to fund development and acquisition related activities.

        Unrestricted cash and cash equivalents totaled $2,733,618,000 at December 31, 2012, an increase of $2,116,765,000 from $616,853,000 at December 31, 2011. The following discussion relates to changes in cash due to operating, investing and financing activities, which are presented in our Consolidated Statements of Cash Flows included elsewhere in this report.

            Operating Activities—Net cash provided by operating activities increased to $540,819,000 in 2012 from $429,354,000 in 2011. The increase was driven primarily by increased cash flows from community operations in 2012 as compared to 2011 and the timing of general corporate expenditures.

            Investing Activities—Net cash used in investing activities of $623,386,000 in 2012 related to investments in assets through development, redevelopment, and acquisitions, partially offset by

59


Table of Contents

    proceeds of $274,018,000 from the sale of real estate. In total, we invested $937,946,000 during 2012 in the following areas:

      •
      We invested approximately $755,363,000 in the development and redevelopment of communities;

      •
      We invested $155,755,000 in the acquisition of four apartment communities, acquisition costs associated with these acquisitions, and costs related to the expected Archstone Acquisition; and

      •
      We had capital expenditures of $26,528,000 for real estate and non-real estate assets.

            Financing Activities—Net cash provided by financing activities totaled $2,199,332,000 in 2012. The net cash provided is due to $2,430,190,000 received from the issuance of common stock, primarily through the underwritten common equity offering we executed in November 2012, through CEP II and CEP III, and stock option exercises, and the proceeds from our $450,000,000 and $250,000,000 unsecured notes offerings. These proceeds were offset partially by $365,572,000 of dividends paid, repayment of unsecured notes of $381,001,000, the repayment of mortgage notes payable of $110,013,000, and the settlement of an interest rate contract for $54,930,000.

Variable Rate Unsecured Credit Facility

        In September 2011, we entered into a $750,000,000 revolving variable rate unsecured credit facility with a syndicate of banks (the "Credit Facility"). In December 2012, pursuant to an option available under the terms of the Credit Facility, with the approval of the lending syndicate we expanded the aggregate facility size to $1,300,000,000, extended the maturity of the credit facility from September 2015 to April 2017, and amended other sections of the Credit Facility (the "Facility Increase"). We may further extend the term for up to two additional six month periods (for a total extension of one year), provided we are not in default and upon payment of a $975,000 extension fee for each extension option.

        In connection with the Facility Increase, the applicable margin over reference rates used to determine the applicable interest rates on our borrowings from time to time decreased. The Credit Facility now bears interest at varying levels based on the London Interbank Offered Rate ("LIBOR"), rating levels achieved on our unsecured notes and on a maturity schedule selected by us. The current stated pricing is LIBOR plus 1.05% per annum (1.25% on January 31, 2013). The stated spread over LIBOR can vary from LIBOR plus 0.95% to LIBOR plus 1.725% based on our credit ratings.             In addition, a competitive bid option is available for borrowings up to 65% of the Credit Facility amount, which allows banks that are part of the lender consortium to bid to make loans at a rate that is lower than the stated rate if market conditions allow. In connection with the Facility Increase, the annual facility fee was also amended to lower the fee from 0.175% to 0.15% (approximately $1,950,000 based on the $1,300,000,000 facility size and based on our current credit rating).

        We did not have any borrowings outstanding under the Credit Facility and had $42,575,000 outstanding in letters of credit that reduced our borrowing capacity as of January 31, 2013.

Financial Covenants

        We are subject to financial and other covenants contained in the Credit Facility and the indenture under which our unsecured notes were issued. The financial covenants include the following:

    •
    limitations on the amount of total and secured debt in relation to our overall capital structure;

    •
    limitations on the amount of our unsecured debt relative to the undepreciated basis of real estate assets that are not encumbered by property-specific financing; and

60


Table of Contents

    •
    minimum levels of debt service coverage.

        We were in compliance with these covenants at December 31, 2012.

        In addition, our secured borrowings may include yield maintenance, defeasance, or prepayment penalty provisions, which would result in us incurring an additional charge in the event of a full or partial prepayment of outstanding principal before the scheduled maturity. These provisions in our secured borrowings are generally consistent with other similar types of debt instruments issued during the same time period in which our borrowings were secured.

Continuous Equity Offering Program

        In November 2010, we commenced our second continuous equity program ("CEP II"), under which we were authorized to sell up to $500,000,000 of our common stock from time to time during a 36-month period. In conjunction with CEP II, we engaged sales agents who received compensation of approximately 1.5% of the gross sales price for shares sold. For the year ended December 31, 2012 we sold 1,435,215 shares under CEP II at an average sales price of $140.41 per share, for aggregate net proceeds of $198,489,000. From program inception in November 2010 through completion in July 2012, we sold 3,925,980 shares at an average price of $127.36 per share, for aggregate net proceeds of $492,490,000.

        In August 2012, we commenced our third continuous equity program ("CEP III"), under which we may sell up to $750,000,000 of shares of our common stock during a 36-month period. In conjunction with CEP III we have engaged sales agents who receive compensation of approximately 1.5% of the gross sales price for shares sold. From program inception through December 31, 2012, we sold 729,991 shares at an average sales price of $142.09, for net proceeds of $102,168,000.

Underwritten Public Offering of Common Stock

        In December 2012, we issued 16,675,000 shares of our common stock at $130.00 per share. Net proceeds of approximately $2,102,718,000 are expected to be used to repay a portion of the debt we expect to assume in connection with the Archstone Acquisition, to fund the cash consideration due in connection with the Archstone Acquisition, to fund the fees, costs and expenses related thereto or, if the acquisition does not occur, for general corporate purposes.

Future Financing and Capital Needs—Debt and Derivative Maturities

        One of our principal long-term liquidity needs is the repayment of long-term debt at the time that such debt matures. For unsecured notes, a portion of the principal of these notes may be repaid prior to maturity. Early retirement of our unsecured notes could result in gains or losses on extinguishment. If we do not have funds on hand sufficient to repay our indebtedness as it becomes due, it will be necessary for us to refinance the debt. This refinancing may be accomplished by uncollateralized private or public debt offerings, additional debt financing that is secured by mortgages on individual communities or groups of communities, borrowings under our Credit Facility or by equity offerings. Although we believe we will have the capacity to meet our currently anticipated liquidity needs, we cannot assure you that additional debt financing or debt or equity offerings will be available or, if available, that they will be on terms we consider satisfactory.

        We are also party to a $215,000,000 forward interest rate swap agreement, which was executed to reduce the impact of variability in interest rates on a portion of our expected debt issuance activity in 2013. In 2013, based on changes in our capital markets outlook for the year, coupled with our current liquidity position, it is now uncertain as to whether we will issue the anticipated debt for which this interest rate protection agreement was transacted. We expect to settle this position at or prior to its maturity in May 2013 for the fair value at the time of settlement. At the point that we deem the

anticipated debt issuance probable of not occurring, we will record a charge for the reversal of the amount recorded within accumulated other comprehensive income for the forward interest swap agreement. If we do issue the debt as previously anticipated, then the amounts recorded within accumulated other comprehensive income will be recognized as interest expense over the term of the debt. As of January 31, 2013 we had recorded a liability related to the value of this contract of $49,675,000

        In conjunction with our issuance of unsecured notes in September 2012, discussed below, we cash settled a liability associated with a second $215,000,000 forward interest rate swap contract to which we were a party in September 2012 for $54,930,000.

        In addition to the proceeds received from the common equity offering we completed in December 2012 and from the CEP II and CEP III offerings during 2012 and the forward interest rate swap agreement discussed above, the following financing activity occurred during 2012:

    •
    In January 2012, we repaid $179,400,000 principal amount of 5.5% unsecured notes pursuant to their scheduled maturity.

    •
    In February 2012, in conjunction with the acquisition of a community, we assumed the existing 4.61% mortgage note in the amount of $11,958,000 that matures in June 2018, and is secured by the community.

    •
    Also in February 2012, we repaid a variable rate secured mortgage note in the amount of $48,500,000 in advance of its November 2039 scheduled maturity date. In conjunction with the early retirement we incurred a non-cash charge of $1,179,000 for the write off of deferred financing fees which was recognized as a loss on extinguishment of debt on the Consolidated Statements of Comprehensive Income.

    •
    In May 2012, we repaid a variable rate secured mortgage note in the amount of $14,566,000 in accordance with its scheduled maturity date.

    •
    Also in May 2012, in conjunction with the disposition of an operating community, we repaid a variable rate secured mortgage note in the amount of $33,100,000 in advance of its scheduled maturity date. We incurred a charge of $602,000 for a prepayment penalty and the write off of deferred financing fees associated with the early repayment of this note included in income from discontinued operations on the accompanying Consolidated Statements of Comprehensive Income.

    •
    In September 2012, we issued $450,000,000 principal amount of unsecured notes in a public offering under our existing shelf registration statement. The notes mature in September 2022 and were issued at a 2.95% interest rate. The notes have an effective interest rate of approximately 4.30%, including the effect of the interest rate hedge discussed above and offering costs.

    •
    In November 2012, we repaid $201,601,000 principal amount of 6.125% unsecured notes pursuant to their scheduled maturity.

    •
    In December 2012, we issued $250,000,000 principal amount of unsecured notes in a public offering under our existing shelf registration statement. The notes mature in March 2023 and were issued at a 2.85% interest rate. The notes have an effective interest rate of 3.00%, including the effect of offering costs.

        The following table details debt maturities for the next five years, excluding our Credit Facility and amounts outstanding related to communities classified as held for sale, for debt outstanding at December 31, 2012 (dollars in thousands). We are not directly or indirectly (as borrower or guarantor) obligated in any material respect to pay principal or interest of the indebtedness of any unconsolidated entities in which we have any equity or other interest. The information presented in this table may materially change as a result of the expected Archstone Acquisition which we anticipate will occur in the first quarter of 2013.

Future Financing and Capital Needs—Portfolio and Other Activity

        As discussed in this Form 10-K, we have entered into a Purchase Agreement to acquire certain of Archstone's net assets. See discussion under "Contractual Obligations."

        As of December 31, 2012, we had 23 wholly-owned communities under construction, for which a total estimated cost of $983,079,000 remained to be invested. We also had five wholly-owned communities under reconstruction, for which a total estimated cost of $43,090,000 remained to be invested. Substantially all of the capital expenditures necessary to complete the communities currently under construction and reconstruction and fund development costs related to pursuing Development Rights will be funded from:

    •
    our $1,300,000,000 Credit Facility until it expires in 2017;

    •
    cash currently on hand, invested in highly liquid overnight money market funds and repurchase agreements, and short-term investment vehicles;

    •
    retained operating cash;

    •
    the net proceeds from sales of existing communities;

    •
    the issuance of debt or equity securities; and/or

    •
    private equity funding, including joint venture activity.

        Before planned reconstruction activity, including reconstruction activity related to communities owned by the Funds, or the construction of a Development Right begins, we intend to arrange adequate financing to complete these undertakings, although we cannot assure you that we will be able to obtain such financing. In the event that financing cannot be obtained, we may have to abandon Development Rights, write off associated pre-development costs that were capitalized and/or forego reconstruction activity. In such instances, we will not realize the increased revenues and earnings that we expected from such Development Rights or reconstruction activity and significant losses could be incurred.

        From time to time we use joint ventures to hold or develop individual real estate assets. We generally employ joint ventures primarily to mitigate asset concentration or market risk and secondarily as a source of liquidity. We may also use joint ventures related to mixed-use land development opportunities where our partners bring specific development and operational expertise to the venture. Each joint venture or partnership agreement has been individually negotiated, and our ability to operate and/or dispose of a community in our sole discretion may be limited to varying degrees depending on the terms of the joint venture or partnership agreement. We cannot assure you that we will achieve our objectives through joint ventures.

        In evaluating our allocation of capital within our markets, we sell assets that do not meet our long-term investment criteria or when capital and real estate markets allow us to realize a portion of the value created over the past business cycle and redeploy the proceeds from those sales to develop and redevelop communities. Because the proceeds from the sale of communities may not be immediately redeployed into revenue generating assets, the immediate effect of a sale of a community for a gain is to increase net income, but reduce future total revenues, total expenses and NOI. However, we believe that the absence of future cash flows from communities sold will have a minimal impact on our ability to fund future liquidity and capital resource needs.

Unconsolidated Real Estate Investments and Off-Balance Sheet Arrangements

Unconsolidated Investments

        As of December 31, 2012, we had investments in the following unconsolidated real estate entities with ownership interest percentages ranging from 15.2% to 31.3%. We account for these investments in unconsolidated real estate entities under the equity method of accounting. Refer to Note 5 "Investments in Real Estate Entities" of the Consolidated Financial Statements located elsewhere in this report, which includes information on the aggregate assets, liabilities and equity, as well as operating results, and our proportionate share of their operating results.

        Detail of the real estate and associated funding underlying our unconsolidated investments is presented in the following table. The information presented in this table may materially change as a result of the expected Archstone Acquisition which we anticipate will occur in the first quarter of 2013.

Off-Balance Sheet Arrangements

        In addition to our investment interests in unconsolidated real estate entities, we have certain off-balance sheet arrangements with the entities in which we invest. Additional discussion of these entities can be found in Note 5, "Investments in Real Estate Entities," of our Consolidated Financial Statements located elsewhere in this report.

    •
    CVP I, LLC has outstanding tax-exempt, variable rate bonds maturing in November 2036 in the amount of $117,000,000, which have permanent credit enhancement. We agreed to guarantee, under limited circumstances, the repayment to the credit enhancer of any advances it may make in fulfillment of CVP I, LLC's repayment obligations under the bonds. We also guaranteed to the credit enhancer that CVP I, LLC would obtain a final certificate of occupancy for the project (Chrystie Place in New York City), which was obtained in December 2012, satisfying the conditions of the guarantee.

    •
    Subsidiaries of Fund I have 13 loans secured by individual assets with amounts outstanding in the aggregate of $254,354,000, including $23,172,000 for the mortgage note of a Fund I subsidiary that we purchased during 2010. Fund I subsidiary loans have varying maturity dates (or dates after which the loans can be prepaid without penalty), ranging from August 2013 to September 2016. These mortgage loans are secured by the underlying real estate. The mortgage loans are payable by the subsidiaries of Fund I with operating cash flow or disposition proceeds from the underlying real estate. We have not guaranteed the debt of Fund I, nor do we have any obligation to fund this debt should Fund I be unable to do so.

      In addition, as part of the formation of Fund I, we provided to one of the limited partners a guarantee. The guarantee provides that if, upon final liquidation of Fund I, the total amount of all distributions to that partner during the life of Fund I (whether from operating cash flow or property sales) does not equal a minimum of the total capital contributions made by that partner, then we will pay the partner an amount equal to the shortfall, but in no event more than 10% of the total capital contributions made by the partner (maximum of approximately $7,500,000 as of December 31, 2012). As of December 31, 2012, the expected realizable value of the real estate assets owned by Fund I is considered adequate to cover such potential payment to that partner under the expected Fund I liquidation scenario. The estimated fair value of, and our obligation under this guarantee, both at inception and as of December 31, 2012 was not significant and therefore we have not recorded any obligation for this guarantee as of December 31, 2012.

    •
    As of December 31, 2012, subsidiaries of Fund II have 14 loans secured by individual assets with amounts outstanding in the aggregate of $490,078,000 with varying maturity dates (or dates after which the loans can be prepaid without penalty), ranging from November 2014 to September 2019. The mortgage loans are payable by the subsidiaries of Fund II with operating cash flow or disposition proceeds from the underlying real estate. We have not guaranteed the debt of Fund II, nor do we have any obligation to fund this debt should Fund II be unable to do so.

      In addition, as part of the formation of Fund II, we provided to one of the limited partners a guarantee. The guarantee provides that if, upon final liquidation of Fund II, the total amount of all distributions to that partner during the life of Fund II (whether from operating cash flow or property sales) does not equal a minimum of the total capital contributions made by that partner, then we will pay the partner an amount equal to the shortfall, but in no event more

      than 10% of the total capital contributions made by the partner (maximum of approximately $8,910,000 as of December 31, 2012). As of December 31, 2012, the expected realizable value of the real estate assets owned by Fund II is considered adequate to cover such potential payment to that partner under the expected Fund II liquidation scenario. The estimated fair value of, and our obligation under this guarantee, both at inception and as of December 31, 2012 was not significant and therefore we have not recorded any obligation for this guarantee as of December 31, 2012.

    •
    Each individual mortgage loan of Fund I or Fund II was made to a special purpose, single asset subsidiary of the Funds. Each mortgage loan provides that it is the obligation of the respective subsidiary only, except under exceptional circumstances (such as fraud or misapplication of funds) in which case the respective Fund could also have obligations with respect to the mortgage loan. In no event do the mortgage loans provide for recourse against investors in the Funds, including against us or our wholly-owned subsidiaries that invest in the Funds. A default by a Fund or a Fund subsidiary on any loan to it would not constitute a default under any of our loans or any loans of our other "non-Fund" subsidiaries or affiliates. If a Fund subsidiary or a Fund were unable to meet its obligations under a loan, the value of our investment in that Fund would likely decline and we might also be more likely to be obligated under the guarantee we provided to one of the Fund partners in each Fund as described above. If a Fund subsidiary or a Fund were unable to meet its obligations under a loan, we and/or the other investors might evaluate whether it was in our respective interests to voluntarily support the Fund through additional equity contributions and/or take other actions to avoid a default under a loan or the consequences of a default (such as foreclosure of a Fund asset).

      In the future, in the event either of the Funds were unable to meet their obligations under a loan, we cannot predict at this time whether we would provide any voluntary support, or take any other action, as any such action would depend on a variety of factors, including the amount of support required and the possibility that such support could enhance the return of either of the Funds and/or our returns by providing time for performance to improve.

    •
    MVP I, LLC, the entity that owns Avalon at Mission Bay North II, has a loan secured by the underlying real estate assets of the community for $105,000,000. The loan is a fixed rate, interest-only note bearing interest at 6.02%, maturing in December 2015. We have not guaranteed the debt of MVP I, LLC, nor do we have any obligation to fund this debt should MVP I, LLC be unable to do so.

    •
    In July 2012, one of our wholly owned subsidiaries acquired Avalon Del Rey, a 309 apartment home community which was owned by a joint venture in which we held a 30% ownership interest. As part of this transaction, the venture repaid the $43,606,000 variable rate note secured by the community. We paid approximately $67,200,000 to purchase our joint venture partner's 70% interest as well as paying the venture our proportionate share of the note repayment.

    •
    In 2007 we entered into a non-cancelable commitment (the "Commitment") to acquire parcels of land in Brooklyn, New York for an aggregate purchase price of approximately $111,000,000. During 2012 we purchased the remaining outstanding parcels for $27,709,000 satisfying our purchase obligation.

        There are no other lines of credit, side agreements, financial guarantees or any other derivative financial instruments related to or between our unconsolidated real estate entities and us. In evaluating our capital structure and overall leverage, management takes into consideration our proportionate share of the indebtedness of unconsolidated entities in which we have an interest.

Contractual Obligations

        In November 2012, we entered into agreements with (i) Equity Residential and its operating partnership, ERP Operating Partnership LP ("Equity Residential"), (ii) Lehman Brothers Holdings, Inc., ("Lehman"), and (iii) Archstone Enterprise LP ("Archstone"), pursuant to which AvalonBay and Equity Residential will acquire, directly or indirectly, all of the assets and entities owned by and all of the liabilities of Archstone. Under the terms of the agreements, we will acquire approximately 40% of Archstone's assets and liabilities and Equity Residential will acquire approximately 60% of Archstone's assets and liabilities ("Archstone Acquisition"). The transaction is expected to close during the first quarter of 2013.

        As disclosed in November 2012, we expect to purchase the following as part of the Archstone Acquisition, which is subject to adjustment up until the transaction closes:

    •
    66 apartment communities that are expected to be consolidated for financial reporting purposes, containing 22,222 apartment homes, of which six communities are under construction and are expected to contain 1,666 apartment homes upon completion;

    •
    Three parcels of land, which are expected to be wholly owned, and if developed as anticipated, are expected to contain a total of 968 apartment homes;

    •
    Interests in joint ventures the assets of which consist primarily of real estate, for which our ownership percentage is expected to be up to 40%, and that are not expected to be consolidated for financial reporting purposes.

        The Company expects to provide the following consideration for the Archstone Acquisition:

    •
    the issuance of 14,889,706 shares of its common stock to Lehman or its designees;

    •
    cash payment of $669,000,000 to Lehman or its designees;

    •
    the assumption of approximately $3,700,000,000 principal amount of consolidated indebtedness;

    •
    the acquisition with Equity Residential of interests in entities that have preferred units outstanding that may be presented for redemption from time to time. The Company's 40% share of the liquidation value of and accrued dividends on these outstanding Archstone preferred units is approximately $132,200,000 at January 31, 2013; and

    •
    the assumption with Equity Residential of all other liabilities, known or unknown, of Archstone, other than certain excluded liabilities. The Company will share in 40% of the cost of these liabilities.

        Equity Residential and we are jointly and severally liable for most obligations to Lehman related to the Archstone Acquisition. If we and Equity Residential fail to close the Archstone Acquisition by March 26, 2013, then Equity Residential and we could be liable for payment of a termination fee of $800,000,000. The closing of the transaction is also subject to customary closing conditions, which do not include our and Equity Residential's ability to obtain the necessary financing or lender consents for the transaction. Unless otherwise stated, all amounts and disclosures included in this Form 10-K do not include any impact from the anticipated closing of the Archstone Acquisition.

Represents our obligation for cash payment pursuant to the expected Archstone Acquisition. We expect to pay additional non-cash considerations as described in this report.

Inflation and Deflation

        Substantially all of our apartment leases are for a term of one year or less. In an inflationary environment, this may allow us to realize increased rents upon renewal of existing leases or the beginning of new leases. Similarly, in a deflationary rent environment, we may be exposed to declining rents more quickly under these shorter-term leases.

Forward-Looking Statements

        This Form 10-K contains "forward-looking statements" as that term is defined under the Private Securities

        Litigation Reform Act of 1995. You can identify forward-looking statements by our use of the words "believe," "expect," "anticipate," "intend," "estimate," "assume," "project," "plan," "may," "shall," "will" and other similar expressions in this Form 10-K, that predict or indicate future events and trends and that do not report historical matters. These statements include, among other things, statements regarding our intent, belief or expectations with respect to:

    •
    our potential development, redevelopment, acquisition or disposition of communities including completion of the expected Archstone Acquisition;

    •
    the timing and cost of completion of apartment communities under construction, reconstruction, development or redevelopment;

    •
    the timing of lease-up, occupancy and stabilization of apartment communities;

    •
    the pursuit of land on which we are considering future development;

    •
    the anticipated operating performance of our communities;

    •
    cost, yield, revenue, NOI and earnings estimates;

    •
    our declaration or payment of distributions;

    •
    our joint venture and discretionary fund activities;

69


Table of Contents

    •
    our policies regarding investments, indebtedness, acquisitions, dispositions, financings and other matters;

    •
    our qualification as a REIT under the Code;

    •
    the real estate markets in Northern and Southern California and markets in selected states in the Mid-Atlantic, New England, Metro New York/New Jersey and Pacific Northwest regions of the United States and in general;

    •
    the availability of debt and equity financing;

    •
    interest rates;

    •
    general economic conditions including potential impacts from the current economic conditions; and

    •
    trends affecting our financial condition or results of operations.

        We cannot assure the future results or outcome of the matters described in these statements; rather, these statements merely reflect our current expectations of the approximate outcomes of the matters discussed. In addition, these forward-looking statements represent our estimates and assumptions only as of the date of this report. We do not undertake a duty to update these forward-looking statements, and therefore they may not represent our estimates and assumptions after the date of this report. You should not rely on forward-looking statements because they involve known and unknown risks, uncertainties and other factors, some of which are beyond our control. These risks, uncertainties and other factors may cause our actual results, performance or achievements to differ materially from the anticipated future results, performance or achievements expressed or implied by these forward-looking statements. In addition to the factors referred to below, you should carefully review the discussion under Item 1a., "Risk Factors," and the other disclosures elsewhere in this document for further discussion of additional risks and uncertainties associated with our business and these forward-looking statements.

        Some of the factors that could cause our actual results, performance or achievements to differ materially from those expressed or implied by these forward-looking statements include, but are not limited to, the following:

    •
    we may fail to secure development opportunities due to an inability to reach agreements with third parties to obtain land at attractive prices or to obtain desired zoning and other local approvals;

    •
    we may abandon or defer development opportunities for a number of reasons, including changes in local market conditions which make development less desirable, increases in costs of development, increases in the cost of capital or lack of capital availability, resulting in losses;

    •
    construction costs of a community may exceed our original estimates;

    •
    we may not complete construction and lease-up of communities under development or redevelopment on schedule, resulting in increased interest costs and construction costs and a decrease in our expected rental revenues;

    •
    occupancy rates and market rents may be adversely affected by competition and local economic and market conditions which are beyond our control;

    •
    financing may not be available on favorable terms or at all, and our cash flows from operations and access to cost effective capital may be insufficient for the development of our pipeline which could limit our pursuit of opportunities;

70


Table of Contents

    •
    our cash flows may be insufficient to meet required payments of principal and interest, and we may be unable to refinance existing indebtedness or the terms of such refinancing may not be as favorable as the terms of existing indebtedness;

    •
    we may be unsuccessful in our management of Fund I, Fund II or the REIT vehicles that are used with each respective Fund; and

    •
    we may be unsuccessful in managing changes in our portfolio composition.

        In addition, any forward-looking statements or forecasts relating to the business, prospects, operating statistics or financial results that relate to or may be expected to result from the Archstone Acquisition are based on expectations, forecasts and assumptions that are inherently speculative and are subject to substantial risks and uncertainties, many of which we cannot predict with accuracy and some of which we may not have anticipated. As a result, the actual operating statistics and financial results that relate to or may be expected to result from the Archstone Acquisition may differ materially from the Company's forecasts. Risks, uncertainties and other factors related to the Archstone Acquisition that might cause such differences include, among other things, the following: the Archstone Acquisition may not close at the time or on the terms that we currently expect; assumptions concerning the availability and/or terms of financing, including among other things obtaining lender consents to the assumption of indebtedness related to the Archstone Acquisition may not be realized; obtaining joint venture partner consents to the assumption of partnership interest related to the Archstone Acquisitions may not be realized; we may not be able to integrate the assets and operations acquired in the Archstone Acquisition in a manner consistent with our assumptions and/or we may fail to achieve expected efficiencies and synergies; we may encounter liabilities related to the Archstone Acquisition for which we may be responsible that were unknown to us at the time we agreed to the Archstone Acquisition or at the time of this report; and our assumptions concerning risks relating to our lack of control of joint ventures and our ability to successfully dispose of certain assets may not be realized.

Critical Accounting Policies

        The preparation of financial statements in conformity with GAAP requires management to use judgment in the application of accounting policies, including making estimates and assumptions. If our judgment or interpretation of the facts and circumstances relating to various transactions had been different, or different assumptions were made, it is possible that different accounting policies would have been applied, resulting in different financial results or a different presentation of our financial statements. Below is a discussion of the accounting policies that we consider critical to an understanding of our financial condition and operating results that may require complex or significant judgment in their application or require estimates about matters which are inherently uncertain. A discussion of our significant accounting policies, including further discussion of the accounting policies described below, can be found in Note 1, "Organization and Basis of Presentation" of our Consolidated Financial Statements.

Table of Contents

Principles of Consolidation

        We may enter into various joint venture agreements with unrelated third parties to hold or develop real estate assets. We must determine for each of these ventures whether to consolidate the entity or account for our investment under the equity or cost basis of accounting.

        We determine whether to consolidate certain entities based on our rights and obligations under the joint venture agreements, applying the applicable accounting guidance. For investment interests that we do not consolidate, we evaluate the guidance to determine the accounting framework to apply. The application of the rules in evaluating the accounting treatment for each joint venture is complex and requires substantial management judgment. Therefore, we believe the decision to choose an appropriate accounting framework is a critical accounting estimate.

        If we were to consolidate the joint ventures that we accounted for using the equity method at December 31, 2012, our assets would have increased by $1,280,984,000 and our liabilities would have increased by $963,664,000. We would be required to consolidate those joint ventures currently not consolidated for financial reporting purposes if the facts and circumstances changed, including but not limited to the following reasons, none of which are currently expected to occur:

    •
    For entities not considered to be variable interest entities, the nature of the entity changed such that it would be considered a variable interest entity and if we were considered the primary beneficiary.

    •
    For entities in which we do not hold a controlling voting and/or variable interest, the contractual arrangement changed resulting in our investment interest being either a controlling voting and/or variable interest.

        We evaluate our accounting for investments on a regular basis including when a significant change in the design of an entity occurs.

Cost Capitalization

        We capitalize costs during the development of assets beginning when we determine that development of a future asset is probable until the asset, or a portion of the asset, is delivered and is ready for its intended use. For redevelopment efforts, we capitalize costs either (i) in advance of taking homes out of service when significant renovation of the common area has begun until the redevelopment is completed, or (ii) when an apartment home is taken out of service for redevelopment until the redevelopment is completed and the apartment home is available for a new resident. Rental income and operating expenses incurred during the initial lease-up or post-redevelopment lease-up period are fully recognized as they accrue.

        During the development and redevelopment efforts we capitalize all direct costs and indirect costs which have been incurred as a result of the development and redevelopment activities. These costs include interest and related loan fees, property taxes as well as other direct and indirect costs. Interest is capitalized for any project specific financing, as well as for general corporate financing to the extent of our aggregate investment in the projects. Indirect project costs, which include personnel and office and administrative costs that are clearly associated with our development and redevelopment efforts, are also capitalized. Capitalized indirect costs associated with our development and redevelopment activities are comprised primarily of compensation related costs for associates dedicated to our development and redevelopment efforts and total $26,513,000, $23,984,000, and $21,475,000 for 2012, 2011, and 2010, respectively. The estimation of the direct and indirect costs to capitalize as part of our development and redevelopment activities requires judgment and, as such, we believe cost capitalization to be a critical accounting estimate.

Table of Contents

        There may be a change in our operating expenses in the event that there are changes in accounting guidance governing capitalization or changes to our levels of development or redevelopment activity. If changes in the accounting guidance limit our ability to capitalize costs or if we reduce our development and redevelopment activities without a corresponding decrease in indirect project costs, there may be an increase in our operating expenses. For example, if in 2012 our development activities decreased by 10%, and there were no corresponding decrease in our indirect project costs, our operating expenses would have increased by $2,651,000.

        We capitalize pre-development costs incurred in pursuit of Development Rights. These costs include legal fees, design fees and related overhead costs. Future development of these pursuits is dependent upon various factors, including zoning and regulatory approval, rental market conditions, construction costs and availability of capital. Pre-development costs incurred for pursuits for which future development is not yet considered probable are expensed as incurred. In addition, if the status of a Development Right changes, making future development no longer probable, any capitalized pre-development costs are written off with a charge to expense.

        Due to the subjectivity in determining whether a pursuit will result in the development of an apartment community, and therefore should be capitalized, the accounting for pursuit costs is a critical accounting estimate. If we had determined that 10% of our capitalized pursuit costs were associated with Development Rights that were no longer probable of occurring, net income for the year ended December 31, 2012 would have decreased by $2,467,000.

Abandoned Pursuit Costs & Asset Impairment

        We evaluate our real estate and other long-lived assets for impairment when potential indicators of impairment exist. Such assets are stated at cost, less accumulated depreciation and amortization, unless the carrying amount of the asset is not recoverable. If events or circumstances indicate that the carrying amount of a property may not be recoverable, we assess its recoverability by comparing the carrying amount of the property to its estimated undiscounted future cash flows. If the carrying amount exceeds the aggregate undiscounted future cash flows, we recognize an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property. Based on periodic tests of recoverability of long-lived assets, for the years ended December 31, 2012, 2011 and 2010, we did not record any impairment losses for wholly-owned operating real estate assets.

        We expensed costs related to abandoned pursuits, which includes the abandonment of Development Rights and disposition pursuits, in the amounts of $1,757,000 in 2012, $1,957,000 in 2011 and $2,741,000 in 2010. These costs are included in operating expenses, excluding property taxes on the accompanying Consolidated Statements of Operations and Other Comprehensive Income. Abandoned pursuit costs can vary greatly, and the costs incurred in any given period may be significantly different in future years.

        We also assess land held for development for impairment if our intent changes with respect to the development of the land. We did not recognize any impairment charges for land holdings in 2012 or 2010. During 2011, we concluded that we would pursue the sale of two land parcels and, as a result, that the carrying bases of the two land parcels were not fully recoverable. As a result, we recognized an aggregate charge of $12,097,000 for the impairment of these land parcels. We had previously recognized an impairment loss of $9,952,000 in 2008 when we determined that we no longer intended to pursue development of the assets. Our change in intent to pursue disposition of these assets rather than holding for investment triggered the determination that a further impairment of the basis for the land parcels existed. We looked to a combination of internal models and third-party pricing estimates to determine the fair values for these impaired land parcels. Considering our knowledge of multifamily residential development, the fair values of parcels zoned for multifamily development were generated using an internal model. Land parcels zoned for other purposes were valued using third-party estimates

73


Table of Contents

of fair value. For the internally generated fair values, we used a discounted cash flow analysis on the expected cash flows for a multifamily rental community. The cash flow analysis incorporated assumptions that market participants would make, including applying discount factors to the estimated future cash flows of the underlying asset, as well as potential disposition proceeds. The third-party values incorporated the use of estimated rates of return, investment time horizons and sales prices for land parcels considered to be market comparables, adjusted for known differences in critical areas including the existing entitlements (such as zoning and state of infrastructure readiness). Both valuation methods included significant other unobservable inputs and are therefore classified as Level 3 prices in the fair value hierarchy.

        We also evaluate our unconsolidated investments for impairment, considering both the carrying value of the investment, estimated to be the expected proceeds that it would receive if the entity were dissolved and the net assets were liquidated, as well as our proportionate share of any impairment of assets held by unconsolidated investments. During 2011, we concluded that because the market for for-sale housing development had not improved as expected, the investment in an unconsolidated joint venture was impaired and that impairment was other than temporary. As a result, we recognized a charge of $1,955,000 for the impairment of the investment in the unconsolidated joint venture. There were no impairment losses recognized by any of our investments in unconsolidated entities during 2012 or 2010.

        Our focus on value creation through real estate development presents an impairment risk in the event of a future deterioration of the real estate and/or capital markets or a decision by us to reduce or cease development. We cannot predict the occurrence of future events that may cause an impairment assessment to be performed, or the likelihood of any future impairment charges, if any. You should also review Item 1a., "Risk Factors" of this Form 10-K.

REIT Status

        We are a Maryland corporation that has elected to be treated, for federal income tax purposes, as a REIT. We elected to be taxed as a REIT under the Code for the year ended December 31, 1994 and have not revoked such election. A corporate REIT is a legal entity which holds real estate interests and must meet a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its adjusted taxable income to stockholders. As a REIT, we generally will not be subject to corporate level federal income tax on taxable income if we distribute 100% of our taxable income to our stockholders over time periods allowed under the Code. If we fail to qualify as a REIT in any taxable year, we will be subject to federal and state income taxes at regular corporate rates (subject to any applicable alternative minimum tax) and may not be able to elect to qualify as a REIT for four subsequent taxable years. For example, if we failed to qualify as a REIT in 2012, our net income would have decreased by approximately $170,400,000.

        Our qualification as a REIT requires management to exercise significant judgment and consideration with respect to operational matters and accounting treatment. Therefore, we believe our REIT status is a critical accounting estimate.

Acquisition of Investments in Real Estate

        We account for our acquisitions of investments in real estate in accordance with the authoritative guidance for the initial measurement, which requires the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree to be recognized at fair value. Typical assets and liabilities acquired include land, building, furniture, fixtures, and equipment, and identified intangible assets and liabilities, consisting of the value of above-below market leases and in-place leases. In making estimates of fair values for purposes of allocating purchase price, we utilize various sources, including our own analysis of recently acquired and existing comparable properties in our portfolio and other market data.

ITEM 7a.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        We are exposed to market risks from our financial instruments primarily from changes in market interest rates. We do not have exposure to any other significant market risk. We monitor interest rate risk as an integral part of our overall risk management, which recognizes the unpredictability of financial markets and seeks to reduce the potentially adverse effect on our results of operations. Our operating results are affected by changes in interest rates, primarily in short-term LIBOR and the SIFMA index as a result of borrowings under our Credit Facility and outstanding bonds with variable interest rates. In addition, the fair value of our fixed rate unsecured and secured notes are impacted by changes in market interest rates. The effect of interest rate fluctuations on our results of operations historically has been small relative to other factors affecting operating results, such as rental rates and occupancy.

        We currently use interest rate protection agreements (consisting of interest rate swap and interest rate cap agreements) for our risk management objectives, as well as for compliance with the requirements of certain lenders, and not for trading or speculative purposes. In the second quarter of 2011, we entered into forward starting interest rate swap agreements to mitigate the impact of future interest rate changes on our expected issuance of debt in future periods. In addition, we have interest rate caps and interest rate swaps that serve to either convert floating rate borrowings to fixed rate borrowings, or effectively limit the amount of interest rate expense we would incur on a floating rate borrowing. Further discussion of the financial instruments impacted and our exposure is presented below.

        We had $476,935,000 and $548,341,000 in variable rate debt outstanding including fixed rate debt effectively swapped to variable rates through swap agreements, as of 2012 and 2011, respectively. If interest rates on the variable rate debt had been 100 basis points higher throughout 2012 and 2011, our annual interest costs would have increased by approximately $3,969,000 and $6,534,000, respectively, based on balances outstanding during the applicable years.

        As of December 31, 2011 we had entered into fixed interest rate swap agreements to hedge fair value exposure for approximately $75,000,000 of our fixed rate unsecured notes with no similar positions at December 31, 2012. Had the fixed interest rate swap agreements used to hedge fair value exposure not been in place during 2011, our annual interest costs would have been approximately $1,765,000 higher, based on balances outstanding in 2011.

        Because the counterparties providing the interest rate cap and swap agreements are major financial institutions which have an A or better credit rating by the Standard & Poor's Ratings Group and the current valuation of the position is a net liability for us, we do not believe there is exposure at this time to a default by a counterparty provider.

        In addition, changes in interest rates affect the fair value of our fixed rate debt, computed using a discounted cash flow model considering our current market yields, which impacts the fair value of our aggregate indebtedness. Debt securities and notes payable (excluding amounts outstanding under our Credit Facility) with an aggregate carrying value of $3,854,068,000 at December 31, 2012 had an estimated aggregate fair value of $4,077,397,000 at December 31, 2012. Contractual fixed rate debt represented $3,377,133,000 of the carrying value and $3,685,629,000 of the fair value at December 31, 2012. If interest rates had been 100 basis points higher as of December 31, 2012, the fair value of this fixed rate debt would have decreased by approximately $175,930,000.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of
AvalonBay Communities, Inc.:

        We have audited the accompanying consolidated balance sheets of AvalonBay Communities, Inc. as of December 31, 2012 and 2011, and the related consolidated statements of comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2012. Our audits also included the financial statement schedule listed in the Index at Item 15(a)(2). These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of AvalonBay Communities, Inc. at December 31, 2012 and 2011, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2012 in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects, the information set forth therein.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), AvalonBay Communities, Inc.'s internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 22, 2013 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm on
Internal Control Over Financial Reporting

The Board of Directors and Stockholders of
AvalonBay Communities, Inc.:

        We have audited AvalonBay Communities, Inc.'s internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). AvalonBay Communities, Inc.'s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control over Financial Reporting in Item 9a. Our responsibility is to express an opinion on the company's internal control over financial reporting based on our audit.

        We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        In our opinion, AvalonBay Communities, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on the COSO criteria.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of AvalonBay Communities, Inc. as of December 31, 2012 and 2011, and the related consolidated statements of comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2012 of AvalonBay Communities, Inc. and our report dated February 22, 2013 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Basis of Presentation

Organization

        AvalonBay Communities, Inc. (the "Company," which term, unless the context otherwise requires, refers to AvalonBay Communities, Inc. together with its consolidated subsidiaries), is a Maryland corporation that has elected to be taxed as a real estate investment trust ("REIT") under the Code. The Company focuses on the development, acquisition, ownership and operation of apartment communities in high barrier to entry markets of the United States. These markets are located in the New England, Metro New York/New Jersey, Mid-Atlantic, Pacific Northwest and Northern and Southern California regions of the country.

        At December 31, 2012, the Company owned or held a direct or indirect ownership interest in 180 operating apartment communities containing 52,792 apartment homes in nine states and the District of Columbia, of which five communities containing 1,787 apartment homes were under reconstruction. In addition, the Company owned or held a direct or indirect ownership interest in 23 communities under construction that are expected to contain an aggregate of 6,599 apartment homes when completed. The Company also owned or held a direct or indirect ownership interest in rights to develop an additional 34 communities that, if developed as expected, will contain an estimated 9,602 apartment homes.

        Capitalized terms used without definition have the meaning as provided elsewhere in this Form 10-K.

Principles of Consolidation

        The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, certain joint venture partnerships, subsidiary partnerships structured as DownREITs and any variable interest entities that qualified for consolidation. All significant intercompany balances and transactions have been eliminated in consolidation.

        The Company accounts for joint venture entities and subsidiary partnerships that are not variable interest entities in accordance with the guidance applicable to limited partnerships or similar entities. The Company evaluates the partnership of each joint venture entity and determines whether control over the partnership lies with the general partner or, when the limited partners have certain rights, with the limited partners. The Company consolidates an investment when both (i) the Company is the general partner, and (ii) the limited partner interests do not overcome the Company's presumption of control by having either substantive participating rights, the ability to remove the Company as the general partner or the ability to dissolve the partnership.

        The Company generally uses the equity method under all other potential scenarios, including (i) where the Company holds a general partner interest but the presumption of control by the Company is overcome by the limited partner interests as described in the preceding paragraph, and (ii) where the Company holds a noncontrolling limited partner interest in a joint venture. Investments in which the Company has little or no influence are accounted for using the cost method.

Revenue and Gain Recognition

        Rental income related to leases is recognized on an accrual basis when due from residents as required by the accounting guidance applicable to leases, which provides guidance on classification and recognition. In accordance with the Company's standard lease terms, rental payments are generally due

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

on a monthly basis. Any cash concessions given at the inception of the lease are amortized over the approximate life of the lease, which is generally one year.

        The Company accounts for the sale of real estate assets and the related gain recognition in accordance with the accounting guidance applicable to sales of real estate, which establishes standards for recognition of profit on all real estate sales transactions, other than retail land sales. The Company recognizes the sale, and associated gain or loss from the disposition, provided that the earnings process is complete and the Company is not obligated to perform significant activities after the sale.

Real Estate

        Operating real estate assets are stated at cost and consist of land, buildings and improvements, furniture, fixtures and equipment, and other costs incurred during their development, redevelopment and acquisition. Significant expenditures which improve or extend the life of an asset are capitalized. Expenditures for maintenance and repairs are charged to expense as incurred.

        Improvements and upgrades are generally capitalized only if the item exceeds $15,000, extends the useful life of the asset and is not related to making an apartment home ready for the next resident. Purchases of personal property, such as computers and furniture, are generally capitalized only if the item is a new addition and exceeds $2,500. The Company generally expenses purchases of personal property made for replacement purposes.

        Project costs related to the development, construction and redevelopment of real estate projects (including interest and related loan fees, property taxes and other direct costs) are capitalized as a cost of the project. Indirect project costs that relate to several projects are capitalized and allocated to the projects to which they relate. Indirect costs not clearly related to development, construction and redevelopment activity are expensed as incurred. For development, capitalization (i) begins when the Company has determined that development of the future asset is probable, (ii) can be suspended if there is no current development activity underway, but future development is still probable and (iii) ends when the asset, or a portion of an asset, is delivered and is ready for its intended use, or the Company's intended use changes such that capitalization is no longer appropriate. For redevelopment efforts, the Company capitalizes costs either (i) in advance of taking homes out of service when significant renovation of the common area has begun until the redevelopment is completed, or (ii) when an apartment home is taken out of service for redevelopment until the redevelopment is completed and the apartment home is available for a new resident. Rental income and operating costs incurred during the initial lease-up or post-redevelopment lease-up period are recognized as incurred.

        The Company acquired as Development Rights four land parcels improved with office buildings, industrial space and other commercial and residential ventures occupied by unrelated third parties. As of December 31, 2012, the Company is actively pursuing development of three of these parcels. For the land parcel for which the Company either does not have active development activity or does not intend to pursue development, rental revenue and incremental costs from the incidental operations are recognized as a part of net income. For those land parcels for which the Company intends to pursue development, the Company will manage the current improvements until such time as all tenant obligations have been satisfied or eliminated through negotiation, and construction of new apartment communities is ready to begin. Revenue from incidental operations received from the current improvements on these land parcels in excess of any incremental costs are being recorded as a reduction of total capitalized costs of the Development Right and not as part of net income.

1. Organization and Basis of Presentation (Continued)

        In connection with the acquisition of an operating community, the Company identifies and records each asset acquired and liability assumed in such transaction at its estimated fair value at the date of acquisition. The purchase price allocations to tangible assets, such as land, buildings and improvements, and furniture, fixtures and equipment, are reflected in real estate assets and depreciated over their estimated useful lives. Any purchase price allocation to intangible assets, such as in-place leases, is included in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets and amortized over the average remaining lease term of the acquired leases. The fair value of acquired in-place leases is determined based on the estimated cost to replace such leases, including foregone rents during an assumed re-lease period, as well as the impact on projected cash flow of acquired leases with leased rents above or below current market rents. The Company expenses all costs incurred related to acquisitions.

        Depreciation is calculated on buildings and improvements using the straight-line method over their estimated useful lives, which range from seven to thirty years. Furniture, fixtures and equipment are generally depreciated using the straight-line method over their estimated useful lives, which range from three years (primarily computer-related equipment) to seven years.

Income Taxes

        As of December 31, 2012, the Company did not have any unrecognized tax benefits. The Company does not believe that there will be any material changes in its unrecognized tax positions over the next 12 months. The Company is subject to examination by the respective taxing authorities for the tax years 2009 through 2011.

        The Company elected to be taxed as a REIT under the Code for its tax year ended December 31, 1994 and has not revoked such election. A corporate REIT is a legal entity which holds real estate interests and can deduct from its federally taxable income qualifying dividends it pays if it meets a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its adjusted taxable income to stockholders. Therefore, as a REIT the Company generally will not be subject to corporate level federal income tax on taxable income if it distributes 100% of the taxable income over the time period allowed under the Code to its stockholders. The states in which the Company operates have similar tax provisions which recognize the Company as a REIT for state income tax purposes. Management believes that all such conditions for the avoidance of income taxes on ordinary income have been or will be met for the periods presented. Accordingly, no provision for federal and state income taxes has been made. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income. The Company received a net refund of $235,000 for federal excise taxes in 2010, recorded as a reduction of general and administrative expense in the Consolidated Statements of Comprehensive Income. The Company did not incur any charges or receive refunds of excise taxes related to 2011 or 2012. In addition, taxable income from non-REIT activities performed through taxable REIT subsidiaries is subject to federal, state and local income taxes, although no taxes were incurred during 2012.

Deferred Financing Costs

        Deferred financing costs include fees and other expenditures necessary to obtain debt financing and are amortized on a straight-line basis, which approximates the effective interest method, over the shorter of the term of the loan or the related credit enhancement facility, if applicable. Unamortized financing costs are charged to earnings when debt is retired before the maturity date. Accumulated amortization of deferred financing costs was $20,773,000 at December 31, 2012 and $17,574,000 at December 31, 2011.

Cash, Cash Equivalents and Cash in Escrow

        Cash and cash equivalents include all cash and liquid investments with an original maturity of three months or less from the date acquired. Cash in escrow includes construction financing proceeds that are restricted for use in the construction of a specific community. The majority of the Company's cash, cash equivalents and cash in escrows are held at major commercial banks.

Interest Rate Contracts

$75,000,000 of fixed rate debt subject to fair value hedges. Excluding debt on communities classified as held for sale, the Company did not apply hedge accounting for an additional $46,735,000 and $79,835,000 in variable rate debt which is subject to interest rate caps as of December 31, 2012 and December 31, 2011, respectively. See Note 10, "Fair Value," for further discussion of derivative financial instruments.

Comprehensive Income

        Comprehensive income, as reflected on the Consolidated Statements of Comprehensive Income, is defined as all changes in equity during each period except for those resulting from investments by or distributions to shareholders. Accumulated other comprehensive loss, as reflected on the Consolidated Statements of Stockholders' Equity, reflects the effective portion of the cumulative changes in the fair value of derivatives in qualifying cash flow hedge relationships.

Earnings per Common Share

        Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted average number of shares outstanding during the period. All outstanding unvested restricted share awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common shareholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic EPS. Both the unvested restricted shares and other potentially dilutive common shares, and the related impact to earnings, are considered when

Casualty Loss, Abandoned Pursuit Costs and Impairment of Long-Lived Assets

        During the three months ended December 31, 2012 the Company incurred damages related to Superstorm Sandy at certain of its communities on the East Coast. The Company recognized a charge of $1,449,000 for the three months and year ended December 31, 2012 for the casualty loss associated with this damage on the accompanying Consolidated Statements of Comprehensive Income.

        The Company evaluates its real estate and other long-lived assets for impairment when potential indicators of impairment exist. Such assets are stated at cost, less accumulated depreciation and amortization, unless the carrying amount of the asset is not recoverable. If events or circumstances indicate that the carrying amount of a property may not be recoverable, the Company assesses its recoverability by comparing the carrying amount of the property to its estimated undiscounted future cash flows. If the carrying amount exceeds the aggregate undiscounted future cash flows, the Company recognizes an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property. Based on periodic tests of recoverability of long-lived assets, for the years ended December 31, 2012, 2011 and 2010, the Company did not record any impairment losses for wholly-owned operating real estate assets.

        The Company capitalizes pre-development costs incurred in pursuit of new development opportunities for which the Company currently believes future development is probable. Future development of these Development Rights is dependent upon various factors, including zoning and regulatory approval, rental market conditions, construction costs and the availability of capital. Initial pre-development costs incurred for pursuits for which future development is not yet considered probable are expensed as incurred. In addition, if the status of a Development Right changes, making future development by the Company no longer probable, any capitalized pre-development costs are written off with a charge to expense. The Company expensed costs related to abandoned pursuits, which includes the abandonment of Development Rights and disposition pursuits, in the amounts of $1,757,000 in 2012, $1,957,000 in 2011 and $2,741,000 in 2010. These costs are included in operating expenses, excluding property taxes on the accompanying Consolidated Statements of Comprehensive Income. Abandoned pursuit costs can vary greatly, and the costs incurred in any given period may be significantly different in future periods.

        The Company assesses land for impairment if the intent of the Company changes with respect to either the development of, or the expected hold period for, the land. The Company did not recognize any impairment charges for land holdings in 2012 or 2010. During 2011, the Company concluded that the carrying basis of two land parcels were not fully recoverable when the Company decided to pursue the sale of these assets. As a result, the Company recognized an aggregate charge of $12,097,000 for the impairment of these land parcels. The impairment recognized in 2011 was primarily attributable to one of the land parcels, which the Company sold in 2012, as discussed in Note 6, "Real Estate Disposition Activities." The Company had previously recognized an impairment loss of $9,952,000 in 2008 when the Company determined that it no longer intended to pursue development of these two land parcels. At that time, the Company had the intent and ability to hold the assets for the foreseeable future. The Company looked to a combination of internal models and third-party pricing estimates to determine the fair values for these impaired land parcels. Considering the Company's knowledge of multifamily residential development, the fair values of parcels zoned for multifamily development were generated using an internal model. Land parcels zoned for other purposes were valued using third-party estimates of fair value. For the internally generated fair values, the Company used a discounted cash flow analysis on the expected cash flows for a multifamily rental community. The cash flow analysis incorporated assumptions that market participants would make, including applying discount factors to the estimated future cash flows of the underlying asset, as well as potential disposition proceeds. The third-party values incorporated the use of estimated rates of return, investment time horizons and sales prices for land parcels considered to be market comparables, adjusted for known differences in critical areas including the existing entitlements (such as zoning and

state of infrastructure readiness). Both valuation methods included significant other unobservable inputs and are therefore classified as Level 3 prices in the fair value hierarchy.

        The Company also evaluates its unconsolidated investments for impairment, considering both its carrying value of the investment, estimated as the expected proceeds that it would receive if the entity were dissolved and the net assets were liquidated, as well as the Company's proportionate share of any impairment of assets held by unconsolidated investments. There were no impairment losses recognized by any of the Company's investments in unconsolidated entities during the years ended December 31, 2012 and December 31, 2010. During 2011, the Company recognized a charge of $1,955,000 for the impairment of its investment in an unconsolidated joint venture. See discussion in Note 5, "Investments in Real Estate Entities."

Assets Held for Sale & Discontinued Operations

        The Company presents the assets and liabilities of any communities which have been sold, or otherwise qualify as held for sale, separately in the Consolidated Balance Sheets. In addition, the results of operations for those assets that meet the definition of discontinued operations are presented as such in the Company's Consolidated Statements of Comprehensive Income. Held for sale and discontinued operations classifications are provided in both the current and prior periods presented. Real estate assets held for sale are measured at the lower of the carrying amount or the fair value less the cost to sell. Both the real estate assets and corresponding liabilities are presented separately in the accompanying Consolidated Balance Sheets. Subsequent to classification of an asset as held for sale, no further depreciation is recorded. For those assets qualifying for classification as discontinued operations, the specific components of net income presented as discontinued operations include net operating income, depreciation expense and interest expense, net. For periods prior to the asset qualifying for discontinued operations, the Company reclassifies the results of operations to discontinued operations. In addition, the net gain or loss (including any impairment loss) on the eventual disposal of assets held for sale will be presented as discontinued operations when recognized. A change in presentation for held for sale or discontinued operations will not have any impact on the Company's financial condition or results of operations. The Company combines the operating, investing and financing portions of cash flows attributable to discontinued operations with the respective cash flows from continuing operations on the accompanying Consolidated Statements of Cash Flows. The Company had one operating community that qualified for held for sale presentation at December 31, 2012.

Redeemable Noncontrolling Interests

        Redeemable noncontrolling interests are comprised of potential future obligations of the Company, which allow the investors holding the noncontrolling interest to require the Company to purchase their interest. The Company classifies obligations under the redeemable noncontrolling interests at fair value, with a corresponding offset for changes in the fair value recorded in accumulated earnings less dividends. Reductions in fair value are recorded only to the extent that the Company has previously recorded increases in fair value above the redeemable noncontrolling interest's initial basis. The redeemable noncontrolling interests are presented outside of permanent equity as settlement in the Company's common shares, where permitted, may not be within the Company's control. The nature and valuation of the Company's redeemable noncontrolling interests are discussed further in Note 10, "Fair Value."

Derivative Instruments and Hedging Activities

        The Company enters into interest rate swap and interest rate cap agreements (collectively, the "Hedging Derivatives") for interest rate risk management purposes and in conjunction with certain variable rate secured debt to satisfy lender requirements. The Company does not enter into derivative transactions for trading or other speculative purposes. The Company assesses both at inception and on an on-going basis, the effectiveness of qualifying cash flow and fair value hedges. Hedge ineffectiveness is reported as a component of general and administrative expenses. The fair values of the Hedging Derivatives that are in an asset position are recorded in prepaid expenses and other assets. The fair value of the Hedging Derivatives that are in a liability position are included in accrued expenses and other liabilities. Fair value changes for derivatives that are not in qualifying hedge relationships are reported as a component of general and administrative expenses. For the derivative positions that the Company has determined qualify as effective cash flow hedges, the Company has recorded the effective portion of cumulative changes in the fair value of the Hedging Derivatives in accumulated other comprehensive loss. Amounts recorded in accumulated other comprehensive loss will be reclassified into earnings in the periods in which earnings are affected by the hedged cash flow. The Company discontinues the application of cash flow hedge accounting in the event that a hedged forecasted transaction is no longer probable of occurring. The Company will continue to defer any hedging gains or losses recognized up to the point that cash flow hedge accounting was discontinued, and recognize those amounts in earnings over the life of that hedged forecasted transaction, if the hedged forecasted transaction does occur as originally anticipated. In the event that a hedged forecasted transaction becomes probable of not occurring, the Company will reclassify hedging gains or losses from accumulated other comprehensive income into earnings. The effective portion of the change in fair value of the Hedging Derivatives that the Company determined qualified as effective fair value hedges is reported as an adjustment to the carrying amount of the corresponding debt being hedged.

Noncontrolling Interests

        Noncontrolling interests represent our joint venture partners' claims on consolidated investments where the Company owns less than a 100% interest. The Company records these interests at their initial fair value, adjusting the basis prospectively for the joint venture partners' share of the respective consolidated investments' results of operations and applicable changes in ownership.

Use of Estimates

        The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Reclassifications

        Certain reclassifications have been made to amounts in prior years' financial statements to conform to current year presentations.

Recently Adopted Accounting Standards

        In May 2011, the FASB issued guidance on fair value measurement and disclosure requirements. This guidance clarified the rules regarding the application of the highest and best use concept, fair value measurement of an instrument classified in equity and quantitative disclosure about unobservable inputs used in Level 3 prices. In addition, this guidance changes the principles applicable to the fair value measurement of instruments managed within a portfolio, application of premiums and discounts in a fair value measurement and additional disclosures about fair value. The Company adopted the guidance with no material impact on the Company's financial position or results of operations

        In February 2013, the FASB issued guidance on reclassifications out of accumulated other comprehensive income (AOCI). For significant items reclassified out of AOCI to net income in their entirety, reporting is required about the effect of the reclassifications on the respective line items where net income is presented. Additionally, for items that are not reclassified to net income in their entirety, a cross reference to other disclosures is required in the notes. The Company does not anticipate the guidance will have a material impact on the Company's financial position or results of operations.

2. Interest Capitalized

        The Company capitalizes interest during the development and redevelopment of real estate assets. Capitalized interest associated with the Company's development or redevelopment activities totaled $49,556,000 for 2012, $33,863,000 for 2011 and $33,393,000 for 2010.

3. Notes Payable, Unsecured Notes and Credit Facility (Continued)

    •
    In September 2012, the Company issued $450,000,000 principal amount of unsecured notes in a public offering under its existing shelf registration statement. The notes mature in September 2022 and were issued at a 2.95% rate. The notes have an effective interest rate of approximately 4.30%, including the effect of an interest rate hedge and offering costs.

    •
    In November 2012, the Company repaid $201,601,000 principal amount of its 6.125% unsecured notes pursuant to their scheduled maturity.

    •
    In December 2012, the Company issued $250,000,000 principal amount of unsecured notes in a public offering under its existing shelf registration statement. The notes mature in March 2023 and were issued at a 2.85% rate. The notes have an effective interest rate of approximately 3.00%, including the effect of offering costs.

        In September 2011, the Company entered into a $750,000,000 revolving variable rate unsecured credit facility with a syndicate of banks (the "Credit Facility"). In December 2012, pursuant to an option available under the terms of the Credit Facility, with the approval of the syndicate of lenders, the Company increased the aggregate facility size by $550,000,000 to $1,300,000,000, extended the maturity of the Credit Facility from September 2015 to April 2017, and amended other sections of the Credit Facility (the "Facility Increase"). The Company may further extend the term for up to two additional six month periods (for a total extension of one year), provided we are not in default and upon payment of a $975,000 extension fee for each extension option.

        In connection with the Facility Increase, the applicable margin over reference rates used to determine the applicable interest rates on our borrowings from time to time decreased. The Credit Facility bears interest at varying levels based on the London Interbank Offered Rate ("LIBOR"), rating levels achieved on our unsecured notes and on a maturity schedule selected by us. The current stated pricing is LIBOR plus 1.05% per annum (1.25% on December 31, 2012). The stated spread over LIBOR can vary from LIBOR plus 0.95% to LIBOR plus 1.725% based on our credit ratings.             In addition, a competitive bid option is available for borrowings up to 65% of the Credit Facility amount, which allows banks that are part of the lender consortium to bid to make loans at a rate that is lower than the stated rate if market conditions allow. In connection with the Facility Increase, the annual facility fee was also amended to lower the fee from 0.175% to 0.15% (approximately $1,950,000 annually based on the $1,300,000,000 facility size and based on our current credit rating).

        The Company had no borrowings outstanding under the Credit Facility and had $44,883,000 and $52,659,000 outstanding in letters of credit that reduced the borrowing capacity as of December 31, 2012 and December 31, 2011, respectively.

        In the aggregate, secured notes payable mature at various dates from April 2013 through July 2066, and are secured by certain apartment communities and improved land parcels (with a net carrying value of $1,513,526,000 as of December 31, 2012).

        As of December 31, 2012, the Company has guaranteed approximately $245,787,000 of mortgage notes payable held by wholly-owned subsidiaries; all such mortgage notes payable are consolidated for financial reporting purposes. The weighted average interest rate of the Company's fixed rate mortgage notes payable (conventional and tax-exempt) was 5.8% and 5.7% at December 31, 2012 and December 31, 2011, respectively. The weighted average interest rate of the Company's variable rate mortgage notes payable and its Credit Facility, including the effect of certain financing related fees, was 2.7% and 2.3% at December 31, 2012 and December 31, 2011, respectively.

Secured note payments are comprised of the principal pay downs for amortizing mortgage notes.

        The Company's unsecured notes are redeemable at our option, in whole or in part, generally at a redemption price equal to the greater of (i) 100% of their principal amount or (ii) the sum of the present value of the remaining scheduled payments of principal and interest discounted at a rate equal to the yield on U.S. Treasury securities with a comparable maturity plus a spread between 25 and 45 basis points depending on the specific series of unsecured note, plus accrued and unpaid interest to the redemption date. The indenture under which the Company's unsecured notes were issued contains limitations on the amount of debt the Company can incur or the amount of assets that can be used to secure other financing transactions, and other customary financial and other covenants, with which the Company was in compliance at December 31, 2012.

4. Stockholders' Equity

        As of December 31, 2012 and 2011, the Company's charter had authorized for issuance a total of 140,000,000 shares of common stock and 50,000,000 shares of preferred stock.

Any deferred compensation related to the Company's stock option and restricted stock grants during 2012 is not reflected on the Company's Consolidated Balance Sheet as of December 31, 2012, and will not be reflected until earned as compensation cost.

        In December 2012, the Company issued 16,675,000 shares of common stock at $130.00 per share. Net proceeds of approximately $2,102,718,000 are to prefund the expected Archstone Acquisition and related matters, discussed further in Note 7. "Commitments and Contingencies".

        In November 2010, the Company commenced a second continuous equity program ("CEP II"), under which the Company was authorized to sell up to $500,000,000 of its common stock from time to time during a 36-month period. During the year ended December 31, 2012, the Company completed the sale of common stock authorized under CEP II, selling 1,435,215 shares at an average sales price of $140.41 per share, for aggregate net proceeds of $198,489,000. From program inception in November 2010 through completion in 2012, the Company issued 3,925,980 common shares at an average price of $127.36 per share for net proceeds of $492,490,000.

        In August 2012, the Company commenced a third continuous equity program ("CEP III"), under which the Company is authorized to sell up to $750,000,000 of shares of its common stock from time to time during a 36-month period. Actual sales will depend on a variety of factors to be determined by the Company, including market conditions, the trading price of the Company's common stock and determinations by the Company of the appropriate sources of funding for the Company. In conjunction with CEP III, the Company engaged sales agents who receive compensation of approximately 1.5% of the gross sales price for shares sold. During the year ended December 31, 2012, the Company sold 729,991 shares at an average sales price of $142.09 per share, for net proceeds of $102,168,000.

Investments in Unconsolidated Real Estate Entities

        The Company accounts for its investments in unconsolidated real estate entities under the equity method of accounting, except as otherwise noted below, as discussed in Note 1, "Organization and Basis of Presentation," under Principles of Consolidation. The significant accounting policies of the Company's unconsolidated real estate entities are consistent with those of the Company in all material respects.

        As of December 31, 2012, the Company had investments in the following real estate entities:

    •
    CVP I, LLC—In February 2004, the Company entered into a joint venture agreement with an unrelated third-party for the development of Avalon Chrystie Place, a 361 apartment-home community located in New York, New York, for which construction was completed in 2005. The Company holds a 20% equity interest (with a right to 50% of distributions after achievement of a threshold return, which was achieved in 2011 and 2012). The Company is the managing

      member of CVP I, LLC, however, property management services at the community are performed by an unrelated third party.

      As of December 31, 2012, CVP I, LLC has outstanding tax-exempt, variable rate bonds maturing in November 2036 in the amount of $117,000,000 which have permanent credit enhancement. The Company guaranteed to the credit enhancer that CVP I, LLC will obtain a final certificate of occupancy for the project, which was received in 2012, satisfying the Company's obligations under the guarantee. The Company also agreed to guarantee, under limited circumstances, the repayment to the credit enhancer of any advances it may make in fulfillment of CVP I, LLC's repayment obligations under the bonds. Our 80% partner in this venture agreed that it will reimburse us its pro rata share of any amounts paid relative to the outstanding guaranteed obligation. The estimated fair value of and our obligation under the outstanding guarantee, both at inception and as of December 31, 2012, was not significant. As a result the Company has not recorded any obligation associated with the guarantee at December 31, 2012.

    •
    MVP I, LLC—In December 2004, the Company entered into a joint venture agreement with an unrelated third-party for the development of Avalon at Mission Bay North II. Construction of Avalon at Mission Bay North II, a 313 apartment-home community located in San Francisco, California, was completed in December 2006. The Company holds a 25% equity interest in the venture. The Company is responsible for the day-to-day operations of the community and is the management agent subject to the terms of a management agreement. In December 2007, MVP I, LLC executed a fixed-rate conventional loan, which is secured by the underlying real estate assets of the community, for $105,000,000. The loan is an interest-only note bearing interest at 6.02%, maturing in December 2015. The Company has not guaranteed the debt of MVP I, LLC, nor does the Company have any obligation to fund this debt should MVP I, LLC be unable to do so.

    •
    Arna Valley View LP—In connection with the municipal approval process to develop a consolidated community, the Company entered into a limited partnership in February 1999 to develop, finance, own and operate Arna Valley View, a 101 apartment-home community in Arlington, Virginia. This community has affordable rents for 100% of apartment homes related to the tax-exempt bond financing and tax credits used to finance construction of the community. A subsidiary of the Company is the general partner of the partnership with a 0.01% ownership interest. The Company manages the community and is subject to a management agreement. As of December 31, 2012, Arna Valley View has $5,678,000 of variable rate, tax-exempt bonds outstanding, which mature in June 2032. In addition, Arna Valley View has $5,963,000 of 4% fixed rate county bonds outstanding that mature in December 2030. Arna Valley View's debt is neither guaranteed by, nor recourse, to the Company. Due to the Company's limited ownership in this venture and the terms of the management agreement regarding the rights of the limited partners, it is accounted for using the cost method.

    •
    Aria at Hathorne Hill, LLC—In the second quarter of 2007, a wholly-owned taxable REIT subsidiary of the Company entered into an LLC agreement with a joint venture partner to develop 64 for-sale town homes with a projected total capitalized cost of $23,621,000 in Danvers, Massachusetts on an out parcel adjacent to our Avalon Danvers rental apartment community. Approximately 30% of the homes have been built and sold. The out parcel was zoned for for-sale activity, and was contributed to the LLC by a subsidiary of the Company in exchange for

      a 50% ownership interest. During 2011, the Company concluded that because the market for for-sale housing development had not improved as expected, its investment in the venture was impaired and that impairment was other than temporary. As a result, the Company recognized a charge of $1,955,000 for the impairment of the investment in the unconsolidated joint venture, which holds nondepreciable real estate assets. In December 2011, the Company acquired the note that the venture had with a third party lender for $1,700,000.

    •
    Fund I—In March 2005, the Company formed Fund I, a private, discretionary real estate investment vehicle, which acquired and operates communities in the Company's markets. Fund I served as the principal vehicle through which the Company acquired investments in apartment communities, subject to certain exceptions, until March 2008. Fund I has a term that expires in March 2013, plus two one-year extension options. Fund I has nine institutional investors, including the Company. A significant portion of the investments made in Fund I by its investors were made through AvalonBay Value Added Fund, Inc., a Maryland corporation that qualifies as a REIT under the Code (the "Fund I REIT"). A wholly-owned subsidiary of the Company is the general partner of Fund I and, excluding costs incurred in excess of our equity in the underlying net assets of Fund I, has an equity investment of $21,121,000 in Fund I and the Fund I REIT, net of distributions and excluding the purchase by the Company of a mortgage note secured by a Fund I community, representing a 15.2% combined general partner and limited partner equity interest. The Company receives asset management fees, property management fees and redevelopment fees, as well as a promoted interest if certain thresholds are met.

        During 2012, Fund I sold six communities:

    •
    Avalon Lakeside, located in Chicago, IL, for $20,500,000;

    •
    Avalon at Poplar Creek, located in Chicago, IL, for $27,200,000;

    •
    Avalon Lombard, located in Chicago, IL, for $35,450,000;

    •
    Avalon Paseo Place, located in Fremont, CA, for $30,900,000;

    •
    Avalon Skyway, located in San Jose, CA, for $90,000,000; and

    •
    Avalon at Aberdeen Station, located in Aberdeen, NJ, for $66,250,000

        The Company's proportionate share of the gain recognized on the sale of these six communities was $7,971,000.

      Subsidiaries of Fund I have 13 loans secured by individual assets (including a mortgage owned by the Company) with amounts outstanding in the aggregate of $254,354,000. Fund I subsidiary loans have varying maturity dates (or dates after which the loans can be prepaid without penalty), ranging from August 2013 to September 2016. These mortgage loans are secured by the underlying real estate. The mortgage loans are payable by the subsidiaries of Fund I with operating cash flow or disposition proceeds from the underlying real estate. The Company has not guaranteed the debt of Fund I, nor does the Company have any obligation to fund this debt should Fund I be unable to do so.

      In addition, as part of the formation of Fund I, the Company provided to one of the limited partners a guarantee. The guarantee provides that if, upon final liquidation of Fund I, the total amount of all distributions to that partner during the life of Fund I (whether from operating

      cash flow or property sales) does not equal a minimum of the total capital contributions made by that partner, then the Company will pay the partner an amount equal to the shortfall, but in no event more than 10% of the total capital contributions made by the partner (maximum of approximately $7,500,000 as of December 31, 2012). Under the expected Fund I liquidation scenario, as of December 31, 2012, the expected realizable value of the real estate assets owned by Fund I is considered adequate to avoid payment under such guarantee to that partner. The estimated fair value of, and the Company's obligation under this guarantee, both at inception and as of December 31, 2012, was not significant and therefore the Company has not recorded any obligation for this guarantee as of December 31, 2012.

    •
    Fund II—In September 2008, the Company formed Fund II, a private, discretionary real estate investment vehicle which acquired and operates communities in the Company's markets. Fund II served as the exclusive vehicle through which the Company acquired investment interests in apartment communities, subject to certain exceptions, through the close of its investment period in August 2011. Fund II has six institutional investors, including the Company. One of the Company's wholly owned subsidiaries is the general partner of Fund II and excluding costs incurred in excess of our equity in the underlying net assets of Fund II, the Company has made an equity investment of $107,938,000 (net of distributions), representing a 31.3% combined general partner and limited partner equity interest.

      During the year ended December 31, 2012, a subsidiary of Fund II acquired Avalon Watchung, a 334 apartment home community located in Watchung, NJ, for $63,000,000. This was the final acquisition for Fund II.

      Subsidiaries of Fund II have 14 loans secured by individual assets with amounts outstanding in the aggregate of $490,078,000, with maturity dates that vary from November 2014 to September 2019. The mortgage loans are payable by the subsidiaries of Fund II with operating cash flow or disposition proceeds from the underlying real estate. The Company has not guaranteed repayment of this debt, nor does the Company have any obligation to fund this debt should Fund II be unable to do so.

      In addition, as part of the formation of Fund II, the Company provided to one of the limited partners a guarantee. The guarantee provides that if, upon final liquidation of Fund II, the total amount of all distributions to that partner during the life of Fund II (whether from operating cash flow or property sales) does not equal a minimum of the total capital contributions made by that partner, then the Company will pay the partner an amount equal to the shortfall, but in no event more than 10% of the total capital contributions made by the partner (maximum of approximately $8,910,000 as of December 31, 2012). Under the expected Fund II liquidation scenario, as of December 31, 2012, the expected realizable value of the real estate assets owned by Fund II is considered adequate to avoid payment under such guarantee to that partner. The estimated fair value of, and the Company's obligation under this guarantee, both at inception and as of December 31, 2012, was not significant and therefore the Company has not recorded any obligation for this guarantee as of December 31, 2012.

Investments in Consolidated Real Estate Entities

        In February 2012, the Company acquired The Mark Pasadena, located in Pasadena, CA. The Mark Pasadena contains 84 apartment homes and was acquired for a purchase price of $19,400,000. In conjunction with this acquisition, the Company assumed the existing 4.61% fixed-rate mortgage loan with an outstanding principal amount of $11,958,000 which matures in June 2018 and is secured by the community.

        In June 2012, the Company acquired Eaves Cerritos, located in Artesia, CA. Eaves Cerritos contains 151 apartment homes and was acquired for a purchase price of $29,500,000.

        In July 2012, the Company acquired Avalon Del Rey, a 309 apartment home community which was owned by a joint venture in which the Company held a 30% ownership interest. As part of this transaction, the venture repaid the $43,606,000 variable rate note secured by the community. The Company paid approximately $67,200,000 for its joint venture partner's 70% interest as well as contributing its proportionate share of the note repayment to the venture. Upon the acquisition of Avalon Del Rey, the Company consolidated the community, recognized income from its promoted interest of $4,055,000 included in equity in income of unconsolidated equities, and a gain of $14,194,000, as gain on acquisition of unconsolidated entity in the Consolidated Statements of Comprehensive Income. The gain recognized reflects the amount by which the fair value of the Company's previously owned investment interest exceeded its carrying value.

        In December 2012, the Company acquired Eaves Burlington, located in Burlington, MA. Eaves Burlington contains 203 apartment homes and was acquired for a purchase price of $40,250,000.

        The Company accounted for each of these acquisitions as a business combination and recorded the acquired assets and assumed liabilities, including identifiable intangibles, based on their fair values. The Company looked to third party pricing or internal models for the values of the land, and an internal model to determine the fair values of the real estate assets, in place leases and mortgage loan. Given the heterogeneous nature of multifamily real estate, the fair values for the land, real estate assets and in place leases incorporated significant unobservable inputs and therefore are considered to be Level 3 prices within the fair value hierarchy. For the Mark Pasadena, the Company used a discounted cash flow analysis to value the mortgage note, considering the contractual terms of the instrument and observable market-based inputs. The fair value of the mortgage loan is considered a Level 2 price as the majority of the inputs used fall within Level 2 of the fair value hierarchy.

        The Company expenses transaction costs associated with acquisition activity as it is incurred. Expensed transaction costs associated with the acquisitions made by the Company in 2012 as well as costs associated with the Archstone Acquisition totaled $9,593,000, reported as a component of Operating expenses, excluding property taxes on the accompanying Consolidated Statements of Comprehensive Income. Acquisition costs in 2011 and 2010 were not significant.

        In 2010, the Company purchased a non-recourse mortgage note secured by a Fund I operating community, on an arms length basis. Upon acquisition of the note, the Company determined that it had control of the Fund I subsidiary, as a result of its collective equity and debt investments, the relationship between the Company and Fund I, and the nature of the Company's operations being more similar to those of the Fund I subsidiary than those of Fund I. Therefore, the Company consolidates the results of operations and net assets of the Fund I subsidiary.

6. Real Estate Disposition Activities

        During 2012, the Company sold four communities: Waterford, located in Oakland, CA; Avalon Arlington Heights, located in Chicago, IL; and Avalon Wildreed and Avalon Highgrove, both located in Everett, WA. These communities, containing a total of 1,578 apartment homes, were sold for an aggregate price of $268,250,000. The dispositions resulted in an aggregate gain in accordance with GAAP of $145,271,000.

        The Company sold one unimproved land parcel in Chicago, IL, for $12,300,000, resulting in an aggregate gain in accordance with GAAP of $280,000. The Company recorded impairment charges of approximately $16,363,000 related to this land parcels in prior years when it was determined that the site would not be developed.

The Archstone Acquisition

        In November 2012, the Company entered into agreements with (i) Equity Residential and its operating partnership, ERP Operating Partnership LP ("Equity Residential"), (ii) Lehman Brothers Holdings, Inc., ("Lehman"), and (iii) Archstone Enterprise LP ("Archstone"), pursuant to which AvalonBay and Equity Residential will acquire, directly or indirectly, all of the assets and entities owned by, and all of the liabilities of, Archstone. Under the terms of the agreements, the Company will acquire approximately 40% of Archstone's asset and liabilities and Equity Residential will acquire approximately 60% of Archstone's assets and liabilities ("Archstone Acquisition"). The transaction is expected to close during the first quarter of 2013.

        The Company expects to purchase the following as part of the Archstone Acquisition:

    •
    66 apartment communities that are expected to be consolidated for financial reporting purposes, containing 22,222 apartment homes, of which six communities are under construction and are expected to contain 1,666 apartment homes upon completion

    •
    Three parcels of land, which are expected to be wholly owned, and if developed as anticipated, are expected to contain a total of 968 apartment homes;

    •
    Interests in joint ventures, the assets of which consist primarily of real estate, for which the Company's ownership percentage is expected to be up to 40%, and that are not expected to be consolidated for financial reporting purposes.

        The Company expects to provide the following consideration for the Archstone Acquisition:

    •
    the issuance of 14,889,706 shares of its common stock to Lehman or its designees;

    •
    cash payment of $669,000,000 to Lehman or its designees;

    •
    the assumption of approximately $3,700,000,000 principal amount of consolidated indebtedness;

    •
    the acquisition with Equity Residential of interests in entities that have preferred units outstanding that may be presented for redemption from time to time. The Company's 40% share of the liquidation value of and accrued dividends on these outstanding Archstone preferred units is approximately $132,200,000 at December 31, 2012; and

    •
    the assumption with Equity Residential of all other liabilities, known or unknown, of Archstone, other than certain excluded liabilities. The Company will share in 40% of the cost of these liabilities.

        Equity Residential and the Company are jointly and severally liable for most obligations to Lehman related to the Archstone Acquisition. If the Company and Equity Residential fail to close Archstone Acquisition by March 26, 2013, then Equity Residential and the Company could be liable for payment of a termination fee of $800,000,000. The closing of the transaction is also subject to customary closing conditions, which do not include the Company and Equity Residential's ability to obtain the necessary financing or lender consents for the transaction. Unless otherwise stated, all amounts and disclosures included in this Form 10-K do not include any impact from the anticipated closing of the Archstone Acquisition. The final assets acquired and consideration paid related to the Archstone Acquisition is subject to adjustment.

Employment Agreements and Arrangements

        As of December 31, 2012, the Company has employment agreements with three executive officers which expire on December 31, 2015. Under the employment agreements, if the Company terminates the executive without cause the executive will be entitled to a multiple of his covered compensation, which is defined as base salary plus annual cash bonus. For two of the executives, the multiple is two times (three if the termination is in connection with a sale of the Company) and for one of the executives the multiple is one time (two if the termination is in connection with a sale of the Company). The employment agreements generally provide that it would be considered a termination without cause if the executive's title or role is reduced except as permitted by the agreement. The agreements provide, as do the standard restricted stock and option agreements used by the Company for its compensation programs, that upon a termination without cause the executive's restricted stock and options will vest.

        The standard restricted stock and option agreements used by the Company in its compensation program provide that upon an employee's termination without cause or the employee's Retirement (as defined in the agreement), all outstanding stock options and restricted shares of stock held by the employee will vest, and the employee will have up to 12 months to exercise any options then held. Under the agreements, Retirement means a termination of employment and other business relationships, other than for cause, after attainment of age 50, provided that (i) the employee has worked for the Company for at least 10 years, (ii) the employee's age at Retirement plus years of employment with the Company equals at least 70, (iii) the employee provides at least six months written notice of his intent to retire, and (iv) the employee enters into a one year non-compete and employee non-solicitation agreement.

        The Company also has an Officer Severance Program (the "Program"), which applies only in connection with a sale of the Company for the benefit of those officers of the Company who do not have employment agreements. Under the Program, in the event an officer who is not otherwise covered by a severance arrangement is terminated (other than for cause), or the officer chooses to terminate his or her employment for good reason (as defined), in either case within 18 months following a sale event (as defined) of the Company, such officer will generally receive a cash lump sum payment equal to a multiple of the officer's covered compensation (base salary plus annual cash bonus). The multiple is one times for vice presidents and senior vice presidents, two times for executive vice presidents and the CFO, and three times for the CEO. The officer's restricted stock and options would also vest. Costs related to the Company's employment agreements and the Program are deferred and recognized over the requisite service period when considered by management to be probable and estimable.

Construction and Development Contingencies

        In 2007 the Company entered into a commitment to acquire parcels of land in Brooklyn, New York for an aggregate purchase price of approximately $111,000,000, subject to escalations based on the timing of the acquisitions. During 2012 the Company purchased the remaining parcels under the commitment for $27,709,000, satisfying its obligation under the commitment.

Legal Contingencies

        The Company accounts for recoveries from legal matters as a reduction in the legal and related costs incurred associated with the matter, with recoveries in excess of these costs reported as a gain or,

where appropriate, a reduction in the basis of a community to which the suit related. During the year ended December 31, 2011, the Company recognized receipt of settlement proceeds of $1,303,000, related to environmental contamination matters pursued by the Company, reported as a reduction in the consolidated capitalized basis of the related communities.

        In addition, the Company is subject to various other legal proceedings and claims that arise in the ordinary course of business. These matters are frequently covered by insurance. If it has been determined that a loss is probable to occur and can be reasonably estimated, the estimated amount of the loss is recorded in the financial statements. While the resolution of these other matters cannot be predicted with certainty, management currently believes the final outcome of such matters will not have a material adverse effect on the financial position or results of operations of the Company. In instances where the Company has a gain contingency associated with legal proceedings, the Company records a gain in the financial statements, to the extent of a loss recovery, when it is deemed probable to occur, can be reasonably estimated and is considered to be collectible.

Lease Obligations

        The Company owns 11 apartment communities, four communities under construction and two commercial properties, which are located on land subject to land leases expiring between October 2026 and March 2142. Of these leases 14 are accounted for as operating leases recognizing rental expense on a straight-line basis over the lease term. These leases have varying escalation terms, and four of these leases have purchase options exercisable through 2095. The Company incurred costs of $17,604,000, $16,887,000, and $35,356,000 in the years ended December 31, 2012, 2011 and 2010, respectively, related to operating leases. In addition, the Company has one apartment community and two Development Communities located on land subject to a land lease, which are accounted for as capital leases, with a lease obligation of $36,005,000 reported as a component of accrued expenses and other liabilities. Each of these leases have purchase options exercisable through 2046. In addition, the Company leases certain office space, which are accounted for as operating leases.

8. Segment Reporting

        The Company's reportable operating segments are Established Communities, Other Stabilized Communities, and Development/Redevelopment Communities. Annually as of January 1st, the Company determines which of its communities fall into each of these categories and maintains that classification, unless disposition or redevelopment plans regarding a community change, throughout the year for the purpose of reporting segment operations.

8. Segment Reporting (Continued)

    •
    Established Communities (also known as Same Store Communities) are 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 occupancy and operating expenses as of the beginning of the prior year. For the year 2012, the Established Communities are communities that are consolidated for financial reporting purposes, had stabilized occupancy and operating expenses as of January 1, 2011, are not conducting or planning to conduct substantial redevelopment activities and are not held for sale or planned for disposition within the current year. A community is considered to have stabilized occupancy at the earlier of (i) attainment of 95% physical occupancy or (ii) the one-year anniversary of completion of development or redevelopment.

    •
    Other Stabilized Communities includes all other completed communities that have stabilized occupancy, as defined above. Other Stabilized Communities do not include communities that are conducting or planning to conduct substantial redevelopment activities within the current year.

    •
    Development/Redevelopment Communities consists of communities that are under construction and have not received a final certificate of occupancy, communities where the Company owns a majority interest and where substantial redevelopment is in progress or is planned to begin during the current year and communities under lease-up that had not reached stabilized occupancy, as defined above, as of January 1, 2012.

        In addition, the Company owns land for future development and has other corporate assets that are not allocated to an operating segment.

        The Company's segment disclosures present the measure(s) used by the chief operating decision maker for purposes of assessing each segment's performance. The Company's chief operating decision maker is comprised of several members of its executive management team who use net operating income ("NOI") as the primary financial measure for Established Communities and Other Stabilized Communities. NOI is defined by the Company as total revenue less direct property operating expenses. Although the Company considers NOI a useful measure of a community's or communities' operating performance, NOI should not be considered an alternative to net income or net cash flow from operating activities, as determined in accordance with GAAP. NOI excludes a number of income and expense categories as detailed in the reconciliation of NOI to net income.

        The primary performance measure for communities under development or redevelopment depends on the stage of completion. While under development, management monitors actual construction costs against budgeted costs as well as lease-up pace and rent levels compared to budget.

        The following table provides details of the Company's segment information as of the dates specified (dollars in thousands). The segments are classified based on the individual community's status as of the beginning of the given calendar year. Therefore, each year the composition of communities within each business segment is adjusted. Accordingly, the amounts between years are not directly comparable. Segment information for the years ended December 31, 2012, 2011 and 2010 have been adjusted for the real estate assets that were sold from January 1, 2010 through December 31, 2012, or

stock valued at $12,883,000 as part of its stock-based compensation plan during the year ended December 31, 2012. Restricted stock vesting during the year ended December 31, 2012 totaled 318,726 shares and had fair values at the grant date ranging from $48.60 to $149.05 per share. The total fair value of shares vested was $36,337,000, $35,029,000 and $9,805,000 for the years ended December 31, 2012, 2011 and 2010, respectively.

        Total employee stock-based compensation cost recognized in income was $9,961,000, $9,721,000 and $9,906,000 for the years ended December 31, 2012, 2011 and 2010, respectively, and total capitalized stock-based compensation cost was $5,140,000, $5,284,000 and $5,117,000 for the years ended December 31, 2012, 2011 and 2010, respectively. At December 31, 2012, there was a total of $2,230,000 and $6,705,000 in unrecognized compensation cost for unvested stock options and unvested restricted stock, respectively, which does not include estimated forfeitures. The unrecognized compensation cost for unvested stock options and restricted stock is expected to be recognized over a weighted average period of 1.73 and 2.33 years, respectively.

        The Company estimates the forfeiture of stock options and recognizes compensation cost net of the estimated forfeitures. The estimated forfeitures included in compensation cost are adjusted to reflect actual forfeitures at the end of the vesting period. The forfeiture rate at December 31, 2012 was 1.5%. The application of estimated forfeitures did not materially impact compensation expense for the years ended December 31, 2012, 2011 or 2010.

Employee Stock Purchase Plan

        In October 1996, the Company adopted the 1996 Non-Qualified Employee Stock Purchase Plan (as amended, the "ESPP"). Initially 1,000,000 shares of common stock were reserved for issuance under this plan. There are currently 733,935 shares remaining available for issuance under the plan. Full-time employees of the Company generally are eligible to participate in the ESPP if, as of the last day of the applicable election period, they have been employed by the Company for at least one month. All other employees of the Company are eligible to participate provided that, as of the applicable election period, they have been employed by the Company for 12 months. Under the ESPP, eligible employees are permitted to acquire shares of the Company's common stock through payroll deductions, subject to maximum purchase limitations. The purchase period is a period of seven months beginning each April 1 and ending each October 30. The purchase price for common stock purchased under the plan is 85% of the lesser of the fair market value of the Company's common stock on the first day of the applicable purchase period or the last day of the applicable purchase period. The offering dates, purchase dates and duration of purchase periods may be changed, if the change is announced prior to the beginning of the affected date or purchase period. The Company issued 6,260, 6,972 and 8,137 shares and recognized compensation expense of $127,000, $216,000 and $272,000 under the ESPP for the years ended December 31, 2012, 2011 and 2010, respectively. The Company accounts for transactions under the ESPP using the fair value method prescribed by accounting guidance applicable to entities that use employee share purchase plans.

10. Fair Value

Financial Instruments Carried at Fair Value

Derivative Financial Instruments

        The Company reports its interest rate swap and interest rate cap agreements at fair value in the Company's financial statements. In adjusting the fair value of its derivative contracts for the effect of counterparty nonperformance risk, the Company has considered the impact of its net position with a given counterparty, as well as any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. The Company minimizes its credit risk on these transactions by dealing with major, creditworthy financial institutions which have an A or better credit rating by the Standard & Poor's Ratings Group. As part of its on-going control procedures, the Company monitors the credit ratings of counterparties and the exposure of the Company to any single entity, thus minimizing credit risk concentration. The Company believes the likelihood of realizing losses from counterparty non-performance is remote. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives use Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by itself and its counterparties. As of December 31, 2012, the Company assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined it is not significant. As a result, the Company has determined that its derivative valuations are classified in Level 2 of the fair value hierarchy.

        Hedge ineffectiveness did not have a material impact on earnings of the Company for any prior period, and the Company does not anticipate that it will have a material effect in the future.

        The following table summarizes the consolidated Hedging Derivatives at December 31, 2012, excluding derivatives executed to hedge debt on communities classified as held for sale (dollars in thousands):

        Excluding derivatives executed to hedge debt on communities classified as held for sale, the Company had five derivatives designated as cash flow hedges and three derivatives not designated as hedges at December 31, 2012. In connection with the Company's September 2012 unsecured note issuance, the Company settled a forward starting interest rate swap agreement designated as a cash flow hedge of the interest rate variability on the forecasted issuance of the unsecured notes, making a payment of $54,930,000, which amount was included in accumulated other comprehensive loss on the Consolidated Balance Sheets and is being recognized as a component of interest expense, net, over the life of the unsecured notes. Fair value changes for derivatives not in qualifying hedge relationships for the year ended December 31, 2012, were not material. To adjust the Hedging Derivatives in qualifying cash flow

hedges to their fair value and recognize the impact of hedge accounting, the Company recorded an increase in other comprehensive loss of $22,876,000, $85,845,000 and $108,000 during the years ended December 31, 2012, 2011 and 2010, respectively. The Company reclassified $1,889,000 from accumulated other comprehensive loss into earnings for the year ended December 31, 2012. The Company anticipates reclassifying approximately $5,493,000 of hedging losses from accumulated other comprehensive loss into earnings within the next twelve months to offset the variability of cash flows of the hedged items during this period. The Company had two derivatives designated as fair value hedges as of December 31, 2011 which matured prior to December 31, 2012. The Company recorded a decrease in the fair value of these fair value hedges of $1,498,000 for the year ended December 31, 2011.

Redeemable Noncontrolling Interests

        The Company provided a redemption option (the "Put") that allows a joint venture partner of the Company to require the Company to purchase its interest in the investment at a guaranteed minimum amount beginning in June 2022, or earlier if the operating community underlying the joint venture is sold. The Put is payable in cash and has a price determined by a guaranteed return on the joint venture partner's net capital contributions over the term of the partnership. The Company determines the fair value of the Put based on unobservable inputs considering the assumptions that market participants would make in pricing the obligation, applying the contractual guaranteed rate of return to the joint venture partner's net capital contribution balance as of period end. Given the significance of the unobservable inputs, the valuation is classified in Level 3 of the fair value hierarchy.

        The Company issued units of limited partnership interests in DownREITs which provide the DownREIT limited partners the ability to present all or some of their units for redemption for cash as determined by the partnership agreement. Under the DownREIT agreement, for each limited partnership unit, the limited partner is entitled to receive cash in the amount equal to the fair value of the Company's common stock on or about the date of redemption. In lieu of cash redemption, the Company may elect to exchange such units for an equal number of shares of the Company's common stock. The limited partnership units in the DownREIT are valued using the market price of the Company's common stock, a Level 1 price under the fair value hierarchy.

Financial Instruments Not Carried at Fair Value

Cash and Cash Equivalents

        Cash and cash equivalent balances are held with various financial institutions, with cash balances held in principal protected accounts and any cash equivalents held in the form of short term investments that do not expose the Company to principal loss. The Company monitors credit ratings of these financial institutions and the concentration of cash and cash equivalent balances with any one financial institution and believes the likelihood of realizing material losses related to cash and cash equivalent balances is remote. Cash and cash equivalents are carried at their face amounts, which reasonably approximate their fair values.

Other Financial Instruments

        Rents receivable, accounts and construction payable and accrued expenses and other liabilities are carried at their face amounts, which reasonably approximate their fair values.

10. Fair Value (Continued)

        The Company values its unsecured notes using quoted market prices, a Level 1 price within the fair value hierarchy. The Company values its mortgage notes payable and outstanding amounts under the Credit Facility using a discounted cash flow analysis on the expected cash flows of each instrument. This analysis reflects the contractual terms of the instrument, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The process also considers credit valuation adjustments to appropriately reflect the Company's nonperformance risk. The Company has concluded that the value of its mortgage notes payable and amounts outstanding under its Credit Facility are Level 2 prices as the majority of the inputs used to value its positions fall within Level 2 of the fair value hierarchy.

Director Compensation

        Directors of the Company who are also employees receive no additional compensation for their services as a director.

The number of shares of restricted stock (or deferred stock awards) is calculated based on the closing price on the day of the award. Non-employee directors may elect to receive all or a portion of cash payments in the form of a deferred stock award. In addition, the Lead Independent Director receives an annual fee of $30,000 payable in equal quarterly installments of $7,500.
