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 develop, redevelop, acquire, own and operate multifamily communities primarily in New England, the New York/New Jersey metro area, the Mid-Atlantic, the Pacific Northwest, and Northern and Southern California. We focus on leading metropolitan areas in these regions that we believe are characterized by growing employment in high wage sectors of the economy, lower housing affordability and a diverse and vibrant quality of life. We believe these market characteristics offer the opportunity for superior risk-adjusted returns on apartment community investments relative to other markets that do not have these characteristics.

At January 31, 2017, we owned or held a direct or indirect ownership interest in:

•

259 operating apartment communities containing 75,038 apartment homes in 10 states and the District of Columbia, of which 244 communities containing 70,864 apartment homes were consolidated for financial reporting purposes, five communities containing 1,539 apartment homes were held by joint ventures in which we hold an ownership interest, and 10 communities containing 2,635 apartment homes were owned by the Funds (as defined below). Four of the consolidated communities containing 1,671 apartment homes were under redevelopment, as discussed below;


•	27 communities under development, one of which is being developed through a joint venture, that are expected to contain an aggregate of 8,629 apartment homes when completed; and


•	rights to develop an additional 25 communities that, if developed in the manner expected, will contain an estimated 8,487 apartment homes.

We generally obtain ownership in an apartment community by developing a new community on either vacant land or land with improvements that we raze, 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 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.

Table of Contents

Our principal financial goal is to increase long-term shareholder value through the development, redevelopment, acquisition, operation and, when appropriate, disposition of apartment communities 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 interests in apartment communities in our selected markets, (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. We pursue our development, investment and operating activities with the purpose of Creating a Better Way to Live. Our strategic vision is to be the leading apartment company in select US markets, providing a range of distinctive living experiences that customers value. We pursue this vision by targeting what we believe are among the best markets and submarkets, leveraging our strategic capabilities in market research and consumer insight and being disciplined in our capital allocation and balance sheet management. In addition to our in-house development and construction capabilities, we supplement our growth through our in-house redevelopment and acquisition platforms. We believe that our organizational structure, which includes dedicated development and operational teams in each of our regions, and strong culture are key differentiators and provide us with access to highly talented, dedicated and capable associates.

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, 2016, we acquired six apartment communities and disposed of 16 apartment communities, excluding activity for the Funds (as defined below). During the three years ended December 31, 2016, we completed the development of 38 apartment communities and the redevelopment of 19 apartment communities.

On February 27, 2013, pursuant to an asset purchase agreement dated November 26, 2012, the Company, together with Equity Residential, acquired, directly or indirectly, all of the assets owned by Archstone Enterprise LP (“Archstone,” which has since changed its name to Jupiter Enterprise LP), including all of the ownership interests in joint ventures and other entities owned by Archstone, and assumed Archstone’s liabilities, both known and unknown, with certain limited exceptions. Under the terms of the purchase agreement, the Company acquired approximately 40.0% of Archstone's assets and liabilities and Equity Residential acquired approximately 60.0% of Archstone’s assets and liabilities (the “Archstone Acquisition”).

In March 2005, we formed AvalonBay Value Added Fund, L.P. (“Fund I”), a private, discretionary real estate investment vehicle, which we managed and in which we owned 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 2008, Fund I acquired 20 communities. During the three years ended December 31, 2016, we realized our pro rata share of the gain from the sale of the last of the four communities owned by Fund I. Fund I disposed of the last of its communities in 2014, and was dissolved in April 2015.

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. From the commencement of Fund II through the close of its investment period, Fund II acquired 13 operating communities. As of December 31, 2016, Fund II owns three communities containing 1,366 apartment homes. During the three years ended December 31, 2016, we realized our pro rata share of the gain from the sale of nine communities owned by Fund II.

Archstone Multifamily Partners AC LP (the “U.S. Fund”) was formed in July 2011 and is fully invested. As of December 31, 2016, the U.S. Fund owns seven communities containing 1,269 apartment homes, one of which includes a marina containing 229 boat slips. In conjunction with the Archstone Acquisition, through subsidiaries, we acquired and own the general partner of the U.S. Fund and hold a 28.6% interest in the U.S. Fund. During the three years ended December 31, 2016, we realized our pro rata share of the gain from the sale of two communities owned by the U.S. Fund.

Archstone Multifamily Partners AC JV LP (the “AC JV”) is a joint venture in which we acquired Archstone's 20.0% ownership interest. The AC JV was formed in 2011 and as of December 31, 2016, owns three operating apartment communities containing 921 apartment homes, one of which completed development in 2014. The AC JV partnership agreement contains provisions that require us to provide a right of first offer (“ROFO”) to the AC JV in connection with additional opportunities to acquire or develop additional interests in multifamily real estate assets within a specified geographic radius of the existing assets, generally one mile or less. The ROFO restriction expires in 2019.

A more detailed description of Fund I, Fund II, and the U.S. Fund (collectively, the “Funds”), the AC JV and other joint ventures and the related investment activity can be found in the discussion in Note 5, “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.”

Through subsidiaries, the Company and Equity Residential entered into three limited liability company agreements (collectively, the “Residual JV”) through which the Company and Equity Residential acquired (i) certain assets of Archstone that the Company and Equity Residential have substantially divested (the “Residual Assets”), and (ii) various liabilities of Archstone that the Company and Equity Residential agreed to assume in conjunction with the Archstone Acquisition (the “Residual Liabilities”). The Residual Assets included a 20.0% interest in Lake Mendota Investments, LLC and Subsidiaries (“SWIB”), a joint venture which disposed of the last of its communities in 2015, various licenses, insurance policies, contracts, office leases and other miscellaneous assets. The Residual Liabilities include most existing or future litigation and claims related to Archstone’s operations for periods before the close of the Archstone Acquisition, except for (i) claims that principally relate to the physical condition of the assets acquired directly by the Company or Equity Residential, which generally remain the sole responsibility of the Company or Equity Residential, as applicable, and (ii) certain tax and other litigation between Archstone and various equity holders in Archstone related to periods before the close of the Archstone Acquisition, and claims which may arise due to changes in the capital structure of Archstone that occurred prior to closing, for which the seller has agreed to indemnify the Company and Equity Residential. The Company and Equity Residential jointly control the Residual JV and the Company holds a 40.0% economic interest in the Residual JV.

During 2016, we sold 12 operating communities including sales by unconsolidated entities and recognized a gain in accordance with U.S. generally accepted accounting principles (“GAAP”) of $428,370,000. In addition, we sold other real estate primarily composed of ancillary real estate and recognized a gain in accordance with GAAP of $10,224,000.

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 our selected markets, 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, including offices that are in or near the following cities:


•	Bellevue, Washington;


•	Boston, Massachusetts;


•	Fairfield, Connecticut;


•	Irvine, California;


•	Iselin, New Jersey;


•	Long Island, New York;


•	Los Angeles, California;


•	New York, New York;


•	San Diego, California;


•	San Francisco, California;


•	San Jose, California; and


•	Virginia Beach, Virginia.

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.

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 in excess of expenses 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. Any expenses relating to these operations, in excess of any rents received, are accounted for as a reduction in 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 dedicated redevelopment teams 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 undertaking the redevelopment primarily through an occupied turn strategy, in which we continue to operate the community as we install improvements, working to minimize any impact on our current residents.

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.

Table of Contents

As part of the Archstone Acquisition, we acquired, and still own, 14 assets that had previously been contributed by third parties on a tax-deferred basis to an Archstone partnership in which the third parties received ownership interests. To protect the tax-deferred nature of the contribution, the third parties are entitled to cash payments if we trigger tax obligations to the third parties by selling, or failing to maintain sufficient levels of secured financing on, the contributed assets. Our tax protection payment obligations with respect to these assets expire at different times and in some cases don’t expire until the death of a third party who contributed ownership interests to the Archstone partnership. After review and investigation of Archstone’s tax and accounting records, we estimate that, had we sold or taken other triggering actions in 2016 with respect to all 14 assets, the aggregate amount of the tax protection payments that would have been triggered would have been approximately $54,600,000. At the present time, we do not intend to take actions that would cause us to be required to make tax protection payments with respect to any of these assets.

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 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”).

While we have achieved growth in the past through the establishment of discretionary real estate investments funds, which placed certain limitations on our ability to acquire new communities during their investments periods, we are not presently pursuing the formation of a new discretionary real estate investment fund, preferring at this time to maintain flexibility in shaping our portfolio of wholly-owned assets through acquisitions and dispositions.

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:


•	focusing 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 considering the most cost effective approach as well as expertise needed to perform the work;


•	we undertake preventive maintenance regularly to maximize resident safety and satisfaction, as well as to maximize property and equipment life;


•	we have established a customer care center, centralizing and improving the efficiency and consistency in the application of Company policies for many of the administrative tasks associated with owning and operating apartment communities; and


•	we aggressively pursue real estate tax appeals.

On-site property management teams receive bonuses based largely upon the revenue, expense, NOI and customer service metrics 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 may engage a third party to manage leasing and/or maintenance activity at one or more of our communities.

Table of Contents

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 or income from such services if we do so through a “taxable REIT subsidiary,” which is a subsidiary that is treated as a “C corporation” subject to federal income taxes. See “Tax Matters” below.

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 $1,500,000,000 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, 2016, we had a total of 693,410 square feet of rentable retail space, excluding retail space within communities currently under development. Gross rental revenue provided by leased retail space in 2016 was $21,390,000 (1.0% of total revenue). We may also develop a property in conjunction with another real estate company that will own and operate the retail or for-sale residential components of a mixed-use building or project 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 qualify as a REIT unless, because of circumstances or changes to the Internal Revenue Code of 1986, as amended (the “Code”) (or the Treasury Regulations thereunder), our Board of Directors determines that it is no longer in our best interest to qualify as a REIT.

Tax Matters

We filed an election with our 1994 federal income tax return to be taxed as a REIT under the Code and intend to maintain our qualification as a REIT in the future. As a qualified REIT, with limited exceptions, such as those described under “Property Management Strategy” above, 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

Table of Contents

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.

Development, redevelopment, construction and operating 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, 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;


•	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.

The construction and maintenance of our communities includes a risk of major casualty events that could materially damage our property and the property of others and pose the risk of personal injury. While we carry insurance for such risks in amounts we deem reasonable, we cannot assure that such insurance will be adequate, and when we have incurred and in the future may incur such casualties we are subject to losses on account of deductibles and self-insured amounts in any event. Such casualties may also expose us in the future to higher insurance premiums, greater construction or operating costs (either voluntarily assumed by us or as a result of new local regulations), and risks to our reputation among prospective residents or municipalities from which we may seek approvals in the future, all of which could have a material adverse effect on our business and our financial condition and results of operations.

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:


•	corporate restructurings and/or layoffs, 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.

We have seen a recent increase in municipalities considering or being urged by advocacy groups to consider rent control or rent stabilization laws and regulations or take other actions which could limit our ability to raise rents based solely on market conditions. Depending on the nature of such laws or regulations and the number of our communities that become subject to any such restriction on rent increases, our revenues and net income could be adversely affected. For example, in 2016 in Mountain View, California, the voters passed a referendum that would limit rent increases on existing tenants (but not on new move-ins) in communities built before 1995. We have three communities with a total of 946 apartment homes that would be subject to the new law, although the implementation of the Mountain View ordinance is currently stayed in connection with a lawsuit challenging the ordinance filed by the California Apartment Association.

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.

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 for new investments.

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 excluding any 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.

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, 2016, approximately 5.8% 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 a syndicate of commercial banks. 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.

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. Their 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.

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.

Table of Contents

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 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.

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.

Table of Contents

We are exposed to various risks from our 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 that 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 that 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.

We are exposed to risks associated with investment in and management of discretionary real estate investment funds and joint ventures.

We formed Fund II, in which we have an equity interest of 31.3%, and as part of the Archstone Acquisition we acquired equity interests in the U.S. Fund and the AC JV of 28.6% and 20.0%, respectively, which, through wholly-owned subsidiaries, we manage as the general partner and managing member. The investment periods for Fund II and the U.S. Fund are over. The Funds and joint ventures (collectively, the "ventures") present risks, including the following:


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


•	investors in the ventures holding a majority of the partnership interests may remove us as the general partner without cause, in the case of Fund II, subject to our right to receive compensation for an additional period of management fees after such removal and our right to acquire one of the properties then held by such ventures;


•	while we have broad discretion to manage the ventures, 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 ventures 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 ventures, or the REIT entities associated with the ventures, fail to comply with various tax or other regulatory matters.

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 created joint ventures with Equity Residential that manage or have an interest in certain of the acquired assets and liabilities. These structures involve participation in the ventures 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 form for the joint venture arrangements, neither we nor Equity Residential expect to individually have the sole power to control the ventures, and an impasse could occur, which could adversely affect the applicable joint venture and decrease potential returns to us and our investors.

We rely on information technology in our operations, and any breach, interruption or security failure of that technology could have a negative impact on our business, results of operations, financial condition and/or reputation.

Information security risks have generally increased in recent years due to the rise in new technologies and the increased sophistication and activities of perpetrators of cyber attacks.

We collect and hold personally identifiable information of our residents and prospective residents in connection with our leasing and property management activities, and we collect and hold personally identifiable information of our associates in connection with their employment. In addition, we engage third party service providers that may have access to such personally identifiable information in connection with providing necessary information technology and security and other business services to us.

We address potential breaches or disclosure of this confidential personally identifiable information by implementing a variety of security measures intended to protect the confidentiality and security of this information including (among others) engaging reputable, recognized firms to help us design and maintain our information technology and data security systems, including testing and verification of their proper and secure operations on a periodic basis. We also maintain cyber risk insurance to provide some coverage for certain risks arising out of data and network breaches.

Table of Contents

However, there can be no assurance that we will be able to prevent unauthorized access to this information. Any failure in or breach of our operational or information security systems, or those of our third party service providers, as a result of cyber attacks or information security breaches could result in a wide range of potentially serious harm to our business operations and financial prospects, including (among others) disruption of our business and operations, disclosure or misuse of confidential or proprietary information (including personal information of our residents and/or associates), damage to our reputation, and/or potentially significant legal and/or financial liabilities and penalties.

We are exposed to risks that are either uninsurable, not economically insurable or in excess of our insurance coverage, including risks discussed below.

Earthquake risk. 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 and in limited supply. 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.

Severe or inclement weather risk. Particularly in New England and the Metro New York/New Jersey area, we are exposed to risks associated with inclement or severe weather, including hurricanes, severe winter storms and coastal flooding. Severe or inclement weather may result in increased costs, such as losses and costs resulting from repair of water and wind damage, removal of snow and ice, and, in the case of our development communities, delays in construction that result in increased construction costs and delays in realizing rental revenues from a community. In addition, severe or inclement weather could increase the need for maintenance of our communities.

Where we have a geographic concentration of exposures, a single catastrophe that affects a region, such as an earthquake that affects the West Coast or a hurricane or severe winter storm that affects the Mid-Atlantic, Metro New York/New Jersey or New England regions, may have a significant negative effect on our financial condition and results of operations.

Climate change risk. To the extent that significant changes in the climate occur in areas where our communities are located, we may experience extreme weather and changes in precipitation and temperature, all of which may result in physical damage to or a decrease in demand for properties located in these areas or affected by these conditions. Should the impact of climate change be material in nature, including significant property damage to or destruction of our communities, or occur for lengthy periods of time, our financial condition or results of operations may be adversely affected. In addition, changes in federal, state and local legislation and regulation based on concerns about climate change could result in increased capital expenditures on our existing properties and our new development properties (for example, to improve their energy efficiency and/or resistance to inclement weather) without a corresponding increase in revenue, resulting in adverse impacts to our net income.

Terrorism risk. We have significant investments in large metropolitan markets, such as the Metro New York/New Jersey and Washington, D.C. markets, that have in the past been or may in the future be the target of actual or threatened terrorist attacks. Future terrorist attacks in these markets could directly or indirectly damage our communities, both physically and financially, or cause losses that exceed our insurance coverage and that could have a material adverse effect on our business, financial condition and results of operations.

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 and in amounts 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.

Table of Contents

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 these 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. These laws and regulations may impose restrictions on the manner in which our communities may be developed, and noncompliance with these laws and regulations may subject us to fines and penalties.

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 have acquired. We implement an operations and maintenance program at each of the communities at which ACMs are detected.

We are aware that some of our communities have lead paint and have implemented an operations and maintenance program at each of those 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.

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 groundwater 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.

Table of Contents

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 cannot assure you that:


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


•	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.

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 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. Our qualification as a REIT will depend on our satisfaction of certain asset, income, organizational, distribution, shareholder ownership and other requirements on a continuing basis. 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.

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 through our taxable REIT subsidiaries hold certain assets and engage in certain activities that a REIT could not engage in directly. We also use taxable REIT subsidiaries to hold certain assets that we believe would be subject to the 100% prohibited transaction tax if sold at a gain outside of a taxable REIT subsidiary. Our taxable REIT subsidiaries are subject to U.S. tax as regular corporations. The Archstone Acquisition increased the amount of assets held through our taxable REIT subsidiaries.

Legislative or regulatory action related to federal income tax laws could adversely affect our stockholders and/or our business.

In recent years, numerous legislative, judicial and administrative changes have been made to the federal income tax laws applicable to investments in REITs and similar entities. Additional changes to tax laws are likely to continue to occur in the future, and we cannot assure our stockholders that any such changes will not adversely affect the taxation of a stockholder. In addition, according to publicly released statements, a top legislative priority of the Trump administration and the current Congress may be significant reform of the Code, including significant changes to taxation of business entities and the deductibility of interest expense. There is a substantial lack of clarity around the likelihood, timing and details of any such tax reform and the impact of any potential tax reform on our business and on the price of our common stock. We cannot assure you that changes to tax laws and regulations will not have an adverse effect on an investment in our common stock.

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 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. 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 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, Redevelopment Communities and Unconsolidated Communities. While we generally establish the classification of communities on an annual basis, we intend to update the classification of communities during the calendar year to the extent that our plans with regard to the disposition or redevelopment of a community change during the year. The following is a description of each category:

Current Communities are categorized as Established, Other Stabilized, Lease-Up, Redevelopment or Unconsolidated 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 as of the beginning of the respective prior year. The Established Communities for the year ended December 31, 2016 are communities that are consolidated for financial reporting purposes, had stabilized occupancy as of January 1, 2015, 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 are all other completed consolidated 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.


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

•

Redevelopment Communities are consolidated communities where substantial redevelopment is in progress or is planned to begin during the current year. Redevelopment is considered substantial when capital invested during the reconstruction effort is expected to exceed the lesser of $5,000,000 or 10% of the community's pre-redevelopment basis and is expected to have a material impact on the operations of the community, including occupancy levels and future rental rates.


•	Unconsolidated Communities are communities that we have an indirect ownership interest in through our investment interest in an unconsolidated joint venture.

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

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

We currently lease our corporate headquarters located in Arlington, Virginia, as well as our other regional and administrative offices under operating leases.

_________________________________

(1)

We remove a community from our Established Communities portfolio for the upcoming year (and then generally maintain that designation) if we believe that planned activity for a community for the upcoming year will result in that community's expected operations not being comparable to the prior year period. We believe that a community's expected operations will not be comparable to the prior year period when we intend either (i) to undertake a significant capital renovation of the community, such that we would consider the community to be classified as a Redevelopment Community; or (ii) to dispose of a community through a sale or other disposition transaction.


(2)	Avalon at Edgewater was moved from the Established Communities portfolio to the Other Stabilized portfolio as a result of the fire that occurred in January 2015.

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. As of January 31, 2017, our Current Communities consisted of the following:



	Number of communities	Number of apartment homes
Garden-style (1)	135	41,147
Mid-rise	100	26,968
High-rise	24	6,923
Total Current Communities	259	75,038

_________________________________


(1)	Includes 16 communities with 5,186 apartment homes that include town homes.

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


•	fully-equipped kitchens;


•	lofts and vaulted ceilings;


•	walk-in closets;


•	patios/decks; and


•	modern appliances.

Table of Contents

Other features at various communities may include:


•	swimming pools;


•	fitness centers;


•	tennis courts; and


•	wi-fi lounges.

As described in Item 1. “Business,” 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 feature 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 Creating a Better Way To Live helps us achieve higher rental rates and occupancy levels while minimizing resident turnover and operating expenses.

Our Current Communities are located in the following geographic markets:

Table of Contents

We manage and operate substantially all of our Current Communities. During the year ended December 31, 2016, we completed construction of 1,715 apartment homes in eight communities and sold twelve operating communities containing an aggregate of 4,026 apartment homes. The average age of our Current Communities, on a weighted average basis according to number of apartment homes, is 19.3 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 12.5 years.

Of the Current Communities, as of January 31, 2017, we owned (directly or through wholly-owned subsidiaries):

•

242 operating communities, including 226 with a full fee simple, or absolute, ownership interest and 16 that are on land subject to a land lease, four of which are dual-branded communities with each pair of dual-branded communities being governed by a single land lease. The leases expire in October 2026, November 2028, May 2041, July 2046, December 2061, September 2065, November 2067, December 2086, April 2095, May 2105, September 2105, April 2106, November 2106 and March 2142;

•

a general partnership interest and an indirect limited partnership interest in Fund II, the U.S. Fund and the AC JV. Subsidiaries of Fund II own a fee simple interest in three operating communities, subsidiaries of the U.S. Fund own a fee simple interest in seven operating communities, of which one is subject to a land lease, and subsidiaries of the AC JV own a fee simple interest in three 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 three 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 certain of the land leases for which we have an absolute ownership interest that expire in October 2026, November 2028, May 2041, July 2046, December 2086 and April 2095.

We also hold, directly or through wholly-owned subsidiaries, the full fee simple ownership interest in 25 of the 27 Development Communities. One Development Community is being developed within a joint venture and one Development Community is being developed with a private development partner and we will own the multifamily rental portion of the development.

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, 2017, there were 7,500 DownREIT partnership units outstanding. The DownREIT partnership is consolidated for financial reporting purposes.

Development Communities

As of December 31, 2016, we owned or held a direct or indirect interest in 27 Development Communities under construction. We expect these Development Communities, when completed, to add a total of 9,129 apartment homes to our portfolio for a total capitalized cost, including land acquisition costs, of approximately $4,045,000,000. We cannot assure you that we will meet our schedule for construction completion or that we will meet our budgeted costs, either individually, or 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” (including the factors identified under “Forward-Looking Statements”) for further discussion of development activity.

The following table presents a summary of the Development Communities. We hold a fee simple ownership interest in these communities (directly or through a wholly-owned subsidiary) unless otherwise noted in the table.

Projected total 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, construction costs, real estate taxes, capitalized interest and loan fees, permits, professional fees, allocated development overhead and other regulatory fees. Projected 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.

(2)	Initial projected occupancy dates are estimates. There can be no assurance that we will pursue to completion any or all of these proposed developments.


(3)	Stabilized operations is defined as the earlier of (i) attainment of 95% or greater physical occupancy or (ii) the one-year anniversary of completion of development.


(4)	Developments containing at least 10,000 square feet of retail space include Avalon Huntington Beach (10,000 square feet), Avalon West Hollywood (32,000 square feet), Avalon Esterra Park (17,000 square feet), Avalon Newcastle Commons I (15,000 square feet), 11 West 61st Street (67,000 square feet), Avalon Belltown Towers (11,000 square feet) and AVA Hollywood (19,000 square feet).

We are developing this project with a private development partner. We will own the rental portion of the development on floors 3 through 19 and the partner will own the for-sale condominium portion on floors 20 through 30 of the development. The information above represents only our portion of the project. We are providing a construction loan to the development partner, expected to be $48,800,000 which together with the partner's contributed equity is expected to fund the condominium portion of the project. A more detailed description of Avalon Sheepshead Bay can be found in Note 5, “Investments in Real Estate Entities,” of the Consolidated Financial Statements set forth in Item 8 of this report.

Redevelopment Communities

As of December 31, 2016, there were four communities under redevelopment. We expect the total capitalized cost to redevelop these communities to be $80,700,000, 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, 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 for attaining restabilized operations, or that we will meet our budgeted costs, either individually or in the aggregate. We anticipate maintaining or increasing 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.

(2)	Restabilized operations is defined as the earlier of (i) attainment of 95% or greater physical occupancy or (ii) the one-year anniversary of completion of redevelopment.

Development Rights

At December 31, 2016, we had $84,293,000 in acquisition and related capitalized costs for direct interests in land parcels we own, and $40,179,000 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 a conditional agreement or option to purchase or lease the land, as well as land associated with the building destroyed in the Edgewater (as defined below) casualty loss not considered a Development Right. Collectively, the land held for development and associated costs for deferred development rights relate to 25 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, 2016 includes $63,082,000 in original land acquisition costs. The original land acquisition cost per home, after consideration of planned sales of associated outparcels and other real estate, ranged from $24,000 per home in Washington to $51,000 per home in Virginia. 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 8,487 apartment homes to our portfolio. Substantially all of these apartment homes will offer features like those offered by the communities we currently own.

For 18 Development Rights, we control the land through a conditional agreement or option to purchase or lease the parcel. While we generally prefer to hold Development Rights through conditional agreements or options to acquire land, for the five remaining Development Rights we either currently own the land, have an ownership interest in a joint venture that owns 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. In addition, two Development Rights are additional development phases of existing stabilized operating communities we own, and will be constructed on land currently associated with those operating communities. During the next 12 months we expect to commence construction of apartment communities on three of the Development Rights for which we currently own the land, with a carrying basis of $49,584,000.

The properties comprising the Development Rights are in different stages of the due diligence and regulatory approval process. The decisions as to which of the Development Rights to invest in, if any, or to continue to pursue once an investment in a Development Right is made, 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 any of the 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. Pre-development costs incurred in the pursuit of Development Rights, 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 2016, we incurred a charge of approximately $4,183,000 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 Item 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 2016 we acquired land parcels for eight Development Rights, as shown in the table below, for an aggregate investment of $101,372,000. For all of the parcels, construction has either started or is expected to start within the next 12 months.

Other Land and Real Estate Assets

We own land parcels with a carrying value of $46,958,000, which we do not currently plan to develop, of which $20,846,000 was under contract to be sold as of December 31, 2016 and was disposed of in January 2017. These parcels consist of both ancillary parcels acquired in connection with Development Rights that we had not planned to develop and land parcels we acquired for development and now intend to sell. During 2016, we recognized an aggregate impairment charge of $10,500,000 relating to three ancillary land parcels which we either sold during the year or intend to sell as of the date of this report. We believe that the current carrying value for all other 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 in the event that there are future 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.

Disposition Activity

We 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 generally 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 acquisition, 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, 2016 to January 31, 2017, we sold our interest in seven wholly-owned communities, containing 2,051 apartment homes. The aggregate gross sales price for these assets was $522,850,000.

Insurance and Risk of Uninsured Losses

We maintain commercial general liability insurance and property insurance with respect to all of our communities. These policies, along with other insurance policies we maintain, have policy specifications, insured and self-insured limits, exclusions and deductibles that we consider commercially reasonable. There are, however, certain types of losses (such as losses arising from nuclear liability or 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, the Hayward Fault or other geological faults that are known or unknown. We cannot assure you that an earthquake would not cause damage or losses greater than our current insured levels. We procure property damage and resulting business interruption insurance coverage with limits of $175,000,000 for any single occurrence and in the annual aggregate for losses resulting from earthquakes. However for communities located in California or Washington, the limit is $150,000,000 for any single occurrence and in the annual aggregate for losses resulting from earthquakes. The deductible applicable to losses resulting from earthquakes occurring in California is five percent of the insured value of each damaged building subject to a minimum of $100,000 and a maximum of $25,000,000 per loss.

Our communities are insured for property damage and business interruption losses through a combination of community specific insurance policies and/or coverage provided under a master property insurance policy covering the majority of our communities. The master policy provides a $400,000,000 limit for any single occurrence, subject to certain sublimits and exclusions. Under the master policy we are subject to a $100,000 deductible per occurrence, as well as additional self-insured retention for the next $350,000 of loss, per occurrence, until the aggregate incurred self-insured retention exceeds $1,500,000 for the policy year.

Our communities are insured for third-party liability losses through a combination of community specific insurance policies and/or coverage provided under a master commercial general liability and umbrella/excess insurance policies. The master commercial general liability and umbrella/excess insurance policies cover the majority of our communities and are subject to certain coverage limitations and exclusions, and require a self-insured retention of $250,000 per occurrence.

We utilize a wholly-owned captive insurance company to insure certain risks, which includes property damage and resulting business interruption losses and other construction related liability risks. The captive is directly responsible for 12% of the losses incurred by the master property insurance policy, on a per occurrence basis, in excess of any applicable deductibles up to the first $50,000,000 of loss.

Just as with office buildings, transportation systems and government buildings, there have been reports that apartment communities could become targets of terrorism. In January 2015, the President signed the Terrorism Risk Insurance Program Reauthorization Act (“TRIPRA”) which extended a program that is designed to make terrorism insurance available through a federal back-stop program. Certain communities are insured for terrorism related losses through this federal program. We have also purchased private-market insurance for property damage due to terrorism with limits of $600,000,000 per occurrence and in the annual aggregate that includes certain coverages (not covered under TRIPRA) such as domestic-based terrorism. This insurance, often referred to as “non-certified” terrorism insurance, is subject to deductibles, limits and exclusions. Our general liability policy provides terrorism coverage through TRIPRA (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 or other environmental contamination. 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 our 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) and limited cyber liability insurance. The crime policies protect us, up to $30,000,000 per occurrence (subject to sublimits and exclusions), from employee theft of money, securities or property. The limited cyber liability insurance is part of our professional liability coverage and has limits of $15,000,000 per occurrence and in the annual aggregate. The cyber liability coverage protects us from certain claims arising out of data breach, wrongful acts, data privacy issues and media liability.

The amount of insurance we maintain may not be sufficient to cover losses.

Maplewood Casualty Loss

In February 2017, a fire occurred at our Avalon Maplewood Development Community, located in Maplewood, NJ, which was under construction and not yet occupied. We are currently assessing our direct losses resulting from the fire, which could vary based on costs and time to rebuild the portion of the Development Community that was destroyed and/or damaged, as well as our potential liability to third parties who may have incurred damages on account of the fire. While we currently believe that our direct losses and any potential liability to third parties will be substantially covered by our insurance policies, including coverage for the replacement cost of the building, third party claims and business interruption loss, subject to deductibles as well as a self-insured portion of the property insurance for which we are obligated for 12% of the first $50,000,000 in losses, we can give no assurances in this regard and continue to evaluate this matter.

Edgewater Casualty Loss

In January 2015, a fire occurred at our Avalon at Edgewater apartment community located in Edgewater, NJ (“Edgewater”). Edgewater consisted of two residential buildings. One building, containing 240 apartment homes, was destroyed. The second building, containing 168 apartment homes, suffered minimal damage and has been repaired. In January 2016, we reached a final settlement with our property and casualty insurers regarding the property damage and lost income related to the Edgewater casualty loss, for which we received aggregate insurance proceeds of $73,150,000, after self-insurance and deductibles. We received $44,142,000 of these recoveries in 2015, and the remaining $29,008,000 in 2016, of which $8,702,000 was recognized as an additional net casualty gain and $20,306,000 as business interruption insurance proceeds.

To date, a number of lawsuits on behalf of former residents have been filed against us, including five purported class actions, 21 individual actions and other subrogation actions by insurers who provided renters insurance to our residents. Having incurred applicable deductibles, we currently believe that all of our remaining liability to third parties will not be material and will in any event be substantially covered by our insurance policies. However, we can give no assurances in this regard and continue to evaluate this matter.

ITEM 3. LEGAL PROCEEDINGS

As discussed immediately above, in January 2015, a fire occurred at the Company's Avalon at Edgewater apartment community in Edgewater, NJ. The Company believes that the fire was caused by sparks from a torch used during repairs being performed by a Company employee who was not a licensed plumber. The Company has since revised its maintenance policies to require that non-flame tools be used for plumbing repairs where possible or, where not possible inside the building envelope, that a qualified third party vendor perform the work in accordance with AvalonBay policies.

The Company has established protocols for processing claims from third parties who suffered losses as a result of the fire, and many third parties have contacted the Company's insurance carrier and settled their claims. Through the date of this Form 10-K, of the 229 occupied apartments destroyed in the fire, the residents of approximately 97 units have settled claims with the Company's insurer, and claims from an additional approximate 34 units are being evaluated by the Company's insurer.

Three class action lawsuits have been filed against the Company on behalf of occupants of the destroyed building and consolidated in the United States District Court for the District of New Jersey. The Company has agreed with class counsel to the terms of a proposed settlement which would provide a claims process (with agreed upon protocols for instructing the adjuster as to how to evaluate claims) and, if needed, an arbitration process to determine damage amounts to be paid to individual claimants covered by the class settlement. On December 9, 2016, class counsel re-filed with the court a motion for preliminary approval of this class settlement, and the Company did not oppose such motion. The Company cannot predict when or if the court will approve the settlement. A fourth class action, being heard in the same federal court, was filed against the Company on behalf of residents of the second Edgewater building that suffered minimal damage. Recently, a fifth class action lawsuit was filed against the Company seeking to certify a class on behalf of both buildings and other third parties. The Company removed this action to the same federal court as the other four and is currently seeking to consolidate it with the fourth class action lawsuit (referenced above). In addition to the class action lawsuits described above, 21 lawsuits representing approximately 150 individual plaintiffs have been filed in the Superior Court of New Jersey Bergen County - Law Division and 20 of these lawsuits are currently pending. Most of the state court cases have been consolidated by the court and the Company expects all of them to be consolidated shortly. The Company believes that it has meritorious defenses to the extent of damages claimed in all of the suits. There are also five subrogation lawsuits that have been filed against the Company by insurers of Edgewater residents who obtained renters insurance; it is the Company’s position that in the majority of the applicable leases the residents waived subrogation rights. One of these lawsuits has been dismissed on that basis and the other four are currently pending in the United States District Court for the District of New Jersey. The District Court recently denied the Company's motion to dismiss which was filed in one of these lawsuits and the Company is currently seeking reconsideration of that decision as well as certification to appeal.

Having settled many third party claims through the insurance claims process, the Company currently believes that any potential remaining liability to third parties (including any potential liability to third parties determined in accordance with the class settlement described above, if approved) will not be material to the Company and will in any event be substantially covered by the Company's insurance policies. However, the Company can give no assurances in this regard and continues to evaluate this matter.

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

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our common stock is traded on the NYSE under the ticker symbol AVB. The following table sets forth the quarterly high and low sales prices per share of our common stock for the years 2016 and 2015, as reported by the NYSE. On January 31, 2017 there were 484 holders of record of an aggregate of 137,330,988 shares of our outstanding common stock. The number of holders does not include individuals or entities who beneficially own shares but whose shares are held of record by a broker or clearing agency, but does include each such broker or clearing agency as one record holder.

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 February 2017, we announced that our Board of Directors declared a dividend on our common stock for the first quarter of 2017 of $1.42 per share, a 5.2% increase over the previous quarterly dividend per share of $1.35. The dividend will be payable on April 17, 2017 to all common stockholders of record as of March 31, 2017.

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.

(5)	Current Communities consist of all communities other than those which are still under construction and for which a certificate or certificates of occupancy for the entire community have not been received.

Reconciliation of Non-GAAP Financial Measures

Funds from Operations, or “FFO,” and FFO adjusted for non-core items, or “Core FFO,” as defined below, are generally considered by management to be appropriate supplemental measures of our operating and financial performance. In calculating FFO, we exclude gains or losses related to dispositions of previously depreciated property and exclude 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. By further adjusting for items that are not considered part of our core business operations, Core FFO allows one to compare the core operating performance of the Company year over year. We believe that in order to understand our operating results, FFO and Core 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 attributable to common stockholders computed in accordance with GAAP, adjusted for:


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


•	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.

We calculate Core FFO as FFO, adjusted for:


•	joint venture gains, costs, and promoted interests;


•	casualty and impairment losses or gains, net;


•	gains or losses from early extinguishment of consolidated borrowings;


•	business interruption and property and casualty insurance proceeds and legal settlements;


•	gains or losses on sales of assets not subject to depreciation;


•	expensed acquisition costs related to business acquisitions that occurred prior to the adoption of ASU 2017-01 as discussed in Note 1, “Organization, Basis of Presentation and Significant Accounting Policies,” of the Consolidated Financial Statements set forth in Item 8 of this report;


•	abandoned pursuits;


•	severance related costs; and


•	other non-core items.

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

Table of Contents

FFO and Core FFO also do 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 above.

The following is a reconciliation of net income attributable to common stockholders to FFO attributable to common stockholders and to Core FFO attributable to common stockholders (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, financial condition 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. Actual results or developments could differ materially from those projected in such statements as a result of the factors described under “Forward-Looking Statements” as well as the risk factors described in Item 1A. “Risk Factors” of this report.

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

Executive Overview

Business Description

We develop, redevelop, acquire, own and operate multifamily apartment communities primarily in New England, the New York/New Jersey metro area, the Mid-Atlantic, the Pacific Northwest, and Northern and Southern California. We focus on leading metropolitan areas that we believe are characterized by growing employment in high wage sectors of the economy, lower housing affordability and a diverse and vibrant quality of life. We believe these market characteristics offer the opportunity for superior risk-adjusted returns on apartment community investments relative to other markets that do not have these characteristics. 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 our selected markets; operating apartment communities; and selling communities when they no longer meet our long-term investment strategy or when pricing is attractive.

Our strategic vision is to be the leading apartment company in select US markets, providing a range of distinctive living experiences that customers value. We pursue this vision by targeting what we believe are among the best markets and submarkets, leveraging our strategic capabilities in market research and consumer insight and being disciplined in our capital allocation and balance sheet management. Our communities are predominately upscale and 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 regularly evaluate the allocation of our investments by the amount of invested capital and by product type within our individual markets.

Financial Highlights

For the year ended December 31, 2016, net income attributable to common stockholders was $1,034,002,000, an increase of $291,964,000, or 39.3%, over the prior year. The increase is primarily attributable to an increase in NOI from newly developed, acquired and existing operating communities and an increase in real estate sales and related gains. These amounts were partially offset by increases in depreciation and interest expense and a loss on extinguishment of debt in the current year, coupled with a gain on extinguishment of debt in the prior year.

For the year ended December 31, 2016, Established Communities NOI increased by $49,606,000, or 4.8%, over the prior year. The increase was driven by an increase in rental revenue of 4.3%, partially offset by an increase in operating expenses of 3.1% over 2015.

During 2016, we raised approximately $1,668,474,000 of gross capital through the issuance of unsecured notes and the sale of real estate, exclusive of proceeds from the disposition of joint ventures and secured debt assumed in conjunction with acquisitions. The funds raised from the sale of real estate consist of the proceeds from the sale of seven operating communities, one land parcel and ancillary real estate. We believe that our current capital structure will continue to provide financial flexibility to access capital on attractive terms.

We believe our development activity will continue to create long-term value. During 2016, we completed the construction of eight communities containing an aggregate of 1,715 apartment homes for an aggregate total capitalized cost of $510,800,000. We also started the construction of nine communities containing an aggregate of 2,732 apartment homes, which are expected to be completed for an estimated total capitalized cost of $1,588,600,000, including our share of the total capitalized cost for one community being developed within a joint venture in which we own a 55.0% interest. In addition, during 2016 we completed the redevelopment of 10 communities containing an aggregate of 2,739 apartment homes for a total investment of $115,900,000, excluding costs incurred prior to the redevelopment.

Table of Contents

During the year ended December 31, 2016, we sold seven wholly-owned operating communities, containing an aggregate of 2,051 apartment homes, for an aggregate sales price of $522,850,000, resulting in an aggregate gain in accordance with GAAP of $370,301,000. We also sold other real estate, primarily composed of one land parcel which was sold to a joint venture in which we own a 55.0% interest, and ancillary real estate, for an aggregate sales price $41,178,000, resulting in an aggregate gain in accordance with GAAP of $10,224,000.

During the year ended December 31, 2016, we acquired five communities containing an aggregate of 1,265 apartment homes and 40,000 square feet of retail space for an aggregate purchase price of $532,350,000. One community, Avalon Clarendon, was a mixed-use development originally acquired through a joint venture. We established separate legal ownership of the residential and retail, office and public parking components of the venture with our venture partner, and as a result consolidated Avalon Clarendon, reporting the operating results of the community as part of our consolidated operations beginning in October 2016. In conjunction with the acquisition of Avalon Hoboken, we assumed a fixed rate secured mortgage note with a principal balance of $67,904,000 and a contractual interest rate of 4.18% maturing in December 2020. In conjunction with the acquisition of Avalon Columbia Pike, we assumed a fixed rate secured mortgage note with a principal balance of $70,507,000 and a contractual interest rate of 3.38% maturing in November 2019.

We believe that our balance sheet strength, as measured by our current level of indebtedness, our current ability to service interest and other fixed charges, and our current moderate use of financial encumbrances (such as secured financing) provide us with adequate access to liquidity from the capital markets. We expect to be able to meet our reasonably foreseeable liquidity needs, as they arise, through a combination of one or more of the following sources: existing cash on hand; operating cash flows; borrowings under our Credit Facility; secured debt; the issuance of corporate securities (which could include unsecured debt, preferred equity and/or common equity); the sale of apartment communities; or through the formation of joint ventures. See the discussion under Liquidity and Capital Resources.

Communities Overview

As of December 31, 2016 we owned or held a direct or indirect ownership interest in 285 apartment communities containing 83,667 apartment homes in 10 states and the District of Columbia, of which 27 communities were under development and four communities were under redevelopment. Of these communities, 16 were owned by entities that were not consolidated for financial reporting purposes, including three owned by subsidiaries of Fund II, seven owned by the U.S. Fund, three owned by the AC JV and one that is being developed within a joint venture. In addition, we held a direct or indirect ownership interest in Development Rights to develop an additional 25 wholly-owned communities that, if developed as expected, will contain an estimated 8,487 apartment homes.

Our real estate investments consist primarily of Current Communities, Development Communities and Development Rights. Our Current Communities are further distinguished as Established Communities, Other Stabilized Communities, Lease-Up Communities, Redevelopment Communities and Unconsolidated Communities.

Established Communities are generally consolidated communities that were owned and had stabilized occupancy as of the beginning of the prior year, allowing for a meaningful comparison of operating results between years. Other Stabilized Communities are generally all other completed consolidated communities that have stabilized occupancy during the current year. Lease-Up Communities are consolidated communities where construction has been complete for less than one year and stabilized occupancy has not been achieved. Redevelopment Communities are consolidated communities where substantial redevelopment is in progress or is planned to begin during the current year. Unconsolidated Communities are communities that we have an indirect ownership interest in through our investment interest in an unconsolidated joint venture. 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 current and future cash needs and financing activities can be found under Liquidity and Capital Resources.

Table of Contents

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, redeveloped 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 is 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. A comparison of our operating results for 2016, 2015 and 2014 follows (dollars in thousands):

Table of Contents

Net income attributable to common stockholders increased $291,964,000, or 39.3%, to $1,034,002,000 in 2016 primarily due to an increase in NOI from newly developed, acquired and existing operating communities and an increase in real estate sales and related gains. These amounts were partially offset by increases in depreciation and interest expense, and a loss on extinguishment of debt in the current year coupled with a gain on extinguishment of debt in the prior year. Net income attributable to common stockholders increased $58,471,000, or 8.6%, to $742,038,000 in 2015 from 2014 primarily due to an increase in NOI from newly developed and existing operating communities, and gains from net insurance recoveries and the extinguishment of debt, partially offset by a decrease in equity in income of unconsolidated real estate entities.

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 easier comparison of the operating performance of individual assets or groups of assets. In addition, because prospective buyers of real estate have different financing and overhead structures, with varying marginal impact to overhead as a result of acquiring real estate, NOI is considered by many in the real estate industry to be a useful measure for determining the value of a real estate asset or group of assets. We define NOI as total property revenue less direct property operating expenses (including property taxes), and excluding corporate-level income (including management, development and other fees), corporate-level property management and other indirect operating expenses, investments and investment management expenses, expensed acquisition, development and other pursuit costs, net of recoveries, interest expense, net, loss (gain) on extinguishment of debt, net, general and administrative expense, equity in income of unconsolidated real estate entities, depreciation expense, corporate income tax expense, casualty and impairment (gain) loss, net, gain on sale of real estate assets, gain on sale of discontinued operations, income from discontinued operations and net operating income from real estate assets sold or held for sale, not classified as discontinued operations.

NOI does not represent cash generated from operating activities in accordance with GAAP, and 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 indicative of cash available to fund cash needs. Reconciliations of NOI for the years ended December 31, 2016, 2015 and 2014 to net income for each year are as follows (dollars in thousands):

The NOI increases for both 2016 and 2015, as compared to the prior year, consist of changes in the following categories (dollars in thousands):



	Full Year
	2016		2015
Established Communities	$	49,606	$	52,763
Other Stabilized Communities (1)	59,022		28,199

_________________________________


(1)	NOI for the year ended December 31, 2016 includes $20,306 in business interruption insurance proceeds related to the Edgewater casualty loss.

The increase in our Established Communities' NOI in 2016 and 2015 is due to increased rental rates, partially offset by decreased economic occupancy and increased operating expenses.

Rental and other income increased in both 2016 and 2015 compared to the prior years due to additional rental income generated from newly developed, acquired and existing operating communities and an increase in rental rates at our Established Communities. The increase for 2016 is also due to business interruption insurance proceeds received due to the final settlement of the Edgewater casualty loss.

Consolidated Communities—The weighted average number of occupied apartment homes for consolidated communities increased to 67,849 apartment homes for 2016, as compared to 64,211 homes for 2015 and 61,686 homes for 2014. The weighted average monthly revenue per occupied apartment home increased to $2,476 for 2016 as compared to $2,388 in 2015 and $2,254 in 2014.

Established Communities—Rental revenue increased $64,206,000, or 4.3%, to $1,541,034,000 for 2016 from $1,476,828,000 in the prior year. The increase is due to an increase in average rental rates of 4.4% to $2,450 per apartment home, partially offset by a decrease in economic occupancy of 0.1% to 95.5%. Rental revenue increased $66,136,000, or 5.0%, for 2015, as compared to the prior year. 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 2016 as compared to the prior year, as discussed in more detail below.

The Metro New York/New Jersey region accounted for approximately 24.5% of the Established Community rental revenue for 2016 and experienced a rental revenue increase of 2.9% for 2016 over the prior year. Average rental rates increased 2.8% to $2,972 per apartment home, and economic occupancy increased 0.1% to 95.7% for 2016 as compared to 2015. While New York City is absorbing a larger pipeline of new apartment deliveries, suburban markets surrounding the city are more insulated from this new competition, and we expect to see continued growth over the prior year in the Metro New York/New Jersey region in 2017.

The Northern California region accounted for approximately 20.7% of the Established Community rental revenue for 2016 and experienced a rental revenue increase of 6.7% for 2016 over the prior year. Average rental rates increased 6.9% to $2,795 per apartment home, and were partially offset by a 0.2% decrease in economic occupancy to 95.2% for 2016 as compared to 2015. We expect slower job growth and elevated levels of new apartment deliveries will temper growth in 2017 relative to prior years.

The Southern California region accounted for approximately 18.9% of the Established Community rental revenue for 2016 and experienced a rental revenue increase of 6.3% for 2016 over the prior year. Average rental rates increased 6.5% to $2,111 per apartment home, and were partially offset by a 0.2% decrease in economic occupancy to 95.6% for 2016 as compared to 2015. Southern California has seen steady job growth and limited new apartment supply, which we expect will continue to support favorable operating results in 2017.

Table of Contents

The New England region accounted for approximately 15.5% of the Established Community rental revenue for 2016 and experienced a rental revenue increase of 3.4% for 2016 over the prior year. Average rental rates increased 3.6% to $2,314 per apartment home, and were partially offset by a 0.2% decrease in economic occupancy to 95.6% for 2016 as compared to 2015. Stable job growth in the Boston metro area is expected to support apartment demand in 2017. The Fairfield market continues to experience moderate economic growth due to the area’s greater exposure to the financial services sector, which has experienced slower job growth during this recovery than other industries.

The Mid-Atlantic region accounted for approximately 15.2% of the Established Community rental revenue for 2016 and experienced a rental revenue increase of 1.7% for 2016 over the prior year. Average rental rates increased 2.0% to $2,134 per apartment home, and were partially offset by a 0.3% decrease in economic occupancy to 95.3% for 2016 as compared to 2015. Although new apartment supply will remain elevated, accelerating job growth is expected to support modest growth in 2017.

The Pacific Northwest region accounted for approximately 5.2% of the Established Community rental revenue for 2016 and experienced a rental revenue increase of 6.3% for 2016 over the prior year. Average rental rates increased 6.2% to $2,168 per apartment home, and economic occupancy increased 0.1% to 94.9% for 2016 as compared to 2015. We believe healthy job growth will continue to support favorable operating results in 2017.

Management, development and other fees decreased $4,348,000 or 43.7%, and $1,103,000, or 10.0%, in 2016 and 2015, respectively, as compared to the prior years. The decrease in 2016 was primarily due to lower property and asset management fees earned as a result of dispositions from Fund II and the U.S. Fund, as well as asset management and disposition fees earned in the prior year not present in 2016 from the Residual JV. The decrease in 2015 was primarily due to lower property and asset management fees earned as a result of dispositions from Fund I and Fund II, partially offset by an increase in disposition fees in 2015 related to the sale of communities owned within the Residual JV.

Direct property operating expenses, excluding property taxes increased $29,260,000, or 7.8%, and $31,471,000, or 9.1%, in 2016 and 2015, respectively, as compared to the prior years. The increases in 2016 and 2015 were primarily due to the addition of newly developed and acquired apartment communities. The increase for 2016 was partially offset by a decrease in snow removal and other costs related to the severe winter storms in our Northeast markets that occurred during the first quarter of 2015, which contributed to the increase in the prior year.

For Established Communities, direct property operating expenses, excluding property taxes, increased $7,256,000, or 2.5%, and $8,207,000, or 3.1%, in 2016 and 2015, respectively, as compared to the prior years. The increase in 2016 was primarily due to increased bad debt expense, compensation and community repairs and maintenance costs, partially offset by decreased utility costs and a decrease in snow removal and other costs related to the severe winter storms in our Northeast markets that occurred during the first quarter of 2015. The increase in 2015 was primarily due to increased repairs and maintenance costs, payroll and benefit costs, and insurance costs, as well as snow removal and other costs related to the severe winter storms in our Northeast markets during the first quarter of 2015.

Property taxes increased $11,338,000, or 5.9%, and $14,865,000, or 8.3%, in 2016 and 2015, respectively, as compared to the prior years. The increases in 2016 and 2015 were primarily due to the addition of newly developed and acquired apartment communities, increased assessments across our portfolio and successful appeals and reductions of supplemental taxes in the respective prior years in excess of those recognized in the then current year.

For Established Communities, property taxes increased $6,616,000, or 4.4%, and $3,829,000, or 2.8%, in 2016 and 2015, respectively, as compared to the prior years. The increase in 2016 was primarily due to increased assessments as well as appeals and supplemental tax reversals in the prior year in excess of those recognized in the current year. The increase in 2015 was primarily due to successful appeals and reductions of supplemental taxes in 2014 in excess of those in 2015, related primarily to our West Coast markets. For communities in California, property tax changes are determined by the change in the California Consumer Price Index, with increases limited by law (Proposition 13). Massachusetts also has laws in place to limit property tax increases. We evaluate property tax increases internally and also engage third-party consultants to assist in our evaluations. We appeal property tax increases when appropriate.

Corporate-level property management and other indirect operating expenses decreased $22,000 in 2016, and increased $6,719,000, or 11.1%, in 2015, as compared to the prior years. The increase in 2015 was primarily due to an increase in compensation related costs including certain employee separation costs.

Table of Contents

Expensed acquisition, development and other pursuit costs, net of recoveries primarily reflect the costs incurred related to our asset investment activity, abandoned pursuit costs, which include costs incurred for development pursuits not yet considered probable for development, as well as the abandonment of Development Rights, acquisition pursuits and disposition pursuits, offset by any recoveries associated with acquisitions for periods prior to our ownership. 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 $3,100,000, or 45.4%, and $10,539,000 in 2016 and 2015, respectively, as compared to the prior years. The increase in 2016 was primarily due to costs related to five operating communities acquired in 2016, as well as the non-cash write-off of asset management fee intangibles associated with the disposition of communities in the U.S. Fund. The increase in 2015 was primarily due to receipts in 2014 related to communities acquired as part of the Archstone Acquisition for periods prior to our ownership, which are primarily comprised of property tax and mortgage insurance refunds, as well as increased costs associated with the acquisition of real estate and abandonment of pursuits, as compared to the prior year.

Interest expense, net increased $11,895,000, or 6.8%, and decreased $5,003,000, or 2.8%, in 2016 and 2015, respectively, as compared to the prior years. This category includes interest costs offset by capitalized interest pertaining to development and redevelopment activity, amortization of premium/discount on debt, and interest income. The increase in 2016 was due to an increase in outstanding unsecured indebtedness from net issuance activity in 2015 and 2016, as well as an increase in variable interest rates. The decrease in 2015 was primarily due to the repayment of secured indebtedness in 2015 and increased capitalized interest as a result of our increased development activity, partially offset by an increase in outstanding unsecured indebtedness resulting from the issuance of $875,000,000 aggregate principal amount during 2015.

Loss (gain) on the extinguishment of debt, net reflects prepayment penalties, the write-off of unamortized deferred financing costs and premiums from our debt repurchase and retirement activity, or payments to acquire our outstanding debt at amounts above or below the carrying basis of the debt acquired, excluding costs related to debt secured by assets sold or held for sale. The loss of $7,075,000 for 2016 was primarily due to the prepayment penalty associated with the early repayment of $250,000,000 principal amount of 5.70% coupon unsecured notes and the non-cash write-off of deferred financing costs for the variable rate debt secured by Avalon Walnut Creek. The gain of $26,736,000 for 2015 was primarily due to the write-off of unamortized mark to market adjustments, net of unamortized deferred financing costs and any applicable related prepayment penalties associated with the early repayment of certain debt assumed as part of the Archstone Acquisition.

Depreciation expense increased $53,511,000, or 11.2%, and $35,241,000, or 8.0%, in 2016 and 2015, respectively, as compared to the prior years. The increases in 2016 and 2015 were primarily due to the addition of newly developed apartment communities. The increase in 2016 was also due to the addition of newly acquired apartment communities.

General and administrative expense (“G&A”) increased $2,997,000, or 7.0%, and $1,349,000, or 3.3%, in 2016 and 2015, respectively, as compared to the prior years. The increase in 2016 was primarily due to an increase in legal and consulting fees, as well as increased charitable contributions over the prior year. The increase in 2015 was primarily due to legal settlement proceeds received in 2014 not present in 2015, partially offset by a decrease in compensation expense, including severance, in 2015 as compared to the prior year.

Casualty and impairment (gain) loss, net for 2016 consists of property damage insurance proceeds from the final insurance settlement for the Edgewater casualty loss and net third-party insurance proceeds related to severe winter storms that occurred in 2015 in our Northeast markets, partially offset by impairment charges recognized for ancillary land parcels. Casualty and impairment (gain) loss, net for 2015 consists of Edgewater insurance proceeds received, partially offset by (i) incident and demolition expenses and the write-off of the net book value of the fixed assets destroyed in the fire at Edgewater, (ii) property and casualty damages incurred across several communities in our Northeast markets related to severe winter storms, and (iii) an impairment charge recognized for a parcel of land sold during 2015.

Equity in income of unconsolidated real estate entities decreased $5,056,000, or 7.2%, and $78,748,000, or 52.9%, in 2016 and 2015, respectively, as compared to the prior years. The decrease in 2016 was primarily due to decreased NOI from the ventures due to disposition activity in 2015 and 2016, as well as amounts received in 2015 for Avalon at Mission Bay II, discussed below, partially offset by increased gains from dispositions in 2016. The decrease in 2015 was primarily due to both gains on, and our promoted interests from, the sale of communities in various ventures, including Avalon Chrystie Place, in 2014 in excess of gains on dispositions in 2015. The decrease in 2015 was partially offset by amounts received related to the modification of the joint venture agreement for the entity that owns Avalon at Mission Bay II to eliminate our promoted interest in future distributions, as well as the settlement of outstanding legal claims and net gains on the sales of communities in various ventures.

Table of Contents

Gain on sale of communities increased in 2016 and 2015 as compared to the prior years. The amount of gain realized in a given period depends on many factors, including the number of communities sold, the size and carrying value of the communities sold and the market conditions in the local area. Prior to our adoption of ASU 2014-08 as of January 1, 2014, gain on sale of communities was presented in gain on sale of discontinued operations. The gain of $374,623,000 in 2016 was primarily due to gains on the sale of seven wholly-owned operating communities, and the gain of $115,625,000 in 2015 was due to gains on the sale of three wholly-owned operating communities.

Gain on sale of other real estate increased in 2016 and 2015 as compared to the prior years. The gain of $10,224,000 in 2016 was primarily composed of the gain on the land we sold to an unconsolidated joint venture. The gain of $9,647,000 in 2015 was a result of the gain on sale of air rights, representing the right to increase density for future residential development, and two undeveloped land parcels.

Income tax expense decreased by $1,178,000 in 2016 and by $7,885,000 in 2015, as compared to the prior years. The decreases in 2016 and 2015 were primarily due to the timing of federal income tax expense amounts related to dispositions of our direct and indirect interests in certain real estate assets acquired in the Archstone Acquisition, which were owned through a taxable REIT subsidiary.

Income from discontinued operations represents the net income generated by real estate sold and qualifying as discontinued operations during the period from January 1, 2014 through December 31, 2016. Income from discontinued operations decreased in 2015, as compared to the prior year due to the change in accounting guidance for discontinued operations as discussed above.

Gain on sale of discontinued operations decreased in 2015 as compared to the prior year. After our adoption of ASU 2014-08 as of January 1, 2014, gain on sale of communities is presented separately from gain on sale of discontinued operations.

Liquidity and Capital Resources

We employ a disciplined approach to our liquidity and capital management. When we source capital, we take into account both our view of the most cost effective alternative then available and our desire to maintain a balance sheet that provides us with flexibility. Our principal short-term liquidity needs are to fund:


•	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 before maturity; and


•	normal recurring operating expenses and corporate overhead 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 had unrestricted cash and cash equivalents of $214,994,000 at December 31, 2016, a decrease of $185,513,000 from $400,507,000 at December 31, 2015. 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 $1,143,484,000 in 2016 from $1,056,754,000 in 2015. The change was driven primarily by increased NOI from existing and newly developed and acquired communities and the receipt of business interruption insurance proceeds.

Investing Activities—Net cash used in investing activities totaled $1,037,352,000 in 2016. The net cash used was primarily due to:


•	investment of $1,201,026,000 in the development and redevelopment of communities;


•	acquisition of five operating communities for $393,316,000, which includes the assumption of outstanding secured indebtedness with a par value of $138,411,000; and


•	capital expenditures of $72,852,000 for our operating communities and non-real estate assets.

Table of Contents

These amounts are partially offset by:


•	proceeds from dispositions of $532,717,000; and


•	net distributions from unconsolidated real estate entities of $101,848,000.

Financing Activities—Net cash used in financing activities totaled $291,645,000 in 2016. The net cash used was primarily due to:


•	payment of cash dividends in the amount of $726,749,000;


•	repayment of unsecured notes in the amount of $504,403,000; and


•	repayment of secured notes in the amount of $165,012,000.

These amounts are partially offset by proceeds from the issuance of unsecured notes in the aggregate amount of $1,122,488,000.

Variable Rate Unsecured Credit Facility

In January 2016, we extended the maturity of the Credit Facility from April 2017 to April 2020, and amended other provisions in the Credit Facility. In addition, pursuant to an option available under the terms of the Credit Facility, with the approval of the syndicate of lenders, we increased the aggregate facility size from $1,300,000,000 to $1,500,000,000 (the “Credit Facility Increase”). We may further extend the term for up to nine months, provided we are not in default and upon payment of a $1,500,000 extension fee. In connection with the Credit 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 0.825% per annum (1.60% at January 31, 2017 assuming a one month borrowing rate). The stated spread over LIBOR can vary from LIBOR plus 0.80% to LIBOR plus 1.55% 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 Credit Facility Increase, the annual facility fee was also amended to lower the fee to 0.125% from 0.15%, resulting in a fee of approximately $1,875,000 annually based on the $1,500,000,000 facility size and based on our current credit rating.

We had no borrowings outstanding under the Credit Facility and had $45,321,000 outstanding in letters of credit that reduced our borrowing capacity as of January 31, 2017.

Financial Covenants

We are subject to financial and other covenants contained in the Credit Facility, the Term Loan and the indenture under which our unsecured notes were issued. The principal 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


•	minimum levels of debt service coverage.

We were in compliance with these covenants at December 31, 2016.

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 December 2015, we commenced a fourth continuous equity program (“CEP IV”) under which we may sell up to $1,000,000,000 of our common stock from time to time. Actual sales will depend on a variety of factors to be determined, including market conditions, the trading price of our common stock and determinations of the appropriate sources of funding. In conjunction with CEP IV, we engaged sales agents who will receive compensation of up to 2.0% of the gross sales price for shares sold. CEP IV also allows us to enter into forward sale agreements up to $1,000,000,000 in aggregate sales price of our common stock. We expect that we will physically settle each forward sale agreement on one or more dates prior to the maturity date of that particular forward sale agreement, in which case we will expect to receive aggregate net cash proceeds at settlement equal to the number of shares underlying the particular forward agreement multiplied by the relevant forward sale price. However, we may also elect to cash settle or net share settle a forward sale agreement. In connection with each forward sale agreement, we will pay the relevant forward seller, in the form of a reduced initial forward sale price, commission of up to 2.0% of the sales prices of all borrowed shares of common stock sold. As of December 31, 2016, we had no sales under the program and had not entered into any forward sale agreements. As of January 31, 2017, we had $1,000,000,000 of shares remaining authorized for issuance under this program.

Forward Interest Rate Swap Agreements

During 2015 and 2016, we entered into $1,200,000,000 of forward interest rate swap agreements to reduce the impact of variability in interest rates on a portion of our expected debt issuance activity in 2016 and 2017. During 2016, we settled $400,000,000 of forward interest rate swap agreements in conjunction with the May 2016 unsecured notes issuance, making a payment of $14,847,000. At maturity of the remaining outstanding forward interest rate swap agreements, we expect to cash settle the contracts and either pay or receive cash for the then current fair value. Assuming that we issue the debt as expected, the impact from settling these positions will then be recognized over the life of the issued debt as a yield adjustment.

Future Financing and Capital Needs—Debt Maturities

One of our principal long-term liquidity needs is the repayment of long-term debt at maturity. For both our unsecured and secured notes, a portion of the principal of these notes may be repaid prior to maturity. Early retirement of our unsecured or secured 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 or otherwise provide liquidity to satisfy the debt at maturity. This refinancing may be accomplished by uncollateralized private or public debt offerings, equity issuances, additional debt financing that is secured by mortgages on individual communities or groups of communities or borrowings under our Credit Facility. 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.

The following debt activity occurred during 2016:


•	In January 2016, in conjunction with the disposition of Eaves Trumbull, Avalon Stratford was substituted as collateral for the outstanding fixed rate mortgage note secured by Eaves Trumbull.


•	In January 2016, in conjunction with the acquisition of Avalon Hoboken, we assumed a fixed rate secured mortgage note with a principal balance of $67,904,000 and a contractual interest rate of 4.18% maturing in December 2020.

Future Financing and Capital Needs—Portfolio and Capital Markets Activity

In 2017, we expect to meet our liquidity needs from a variety of internal and external sources, including (i) real estate dispositions, (ii) cash balances on hand as well as cash generated from our operating activities, (iii) borrowing capacity under our Credit Facility and (iv) secured and unsecured debt financings. Additional sources of liquidity in 2017 may include the issuance of common and preferred equity. 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.

Before beginning new construction or reconstruction activity, including activity related to communities owned by unconsolidated joint ventures, we intend to plan 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 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 that we develop, redevelop or acquire, 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 until such time as the proceeds have been redeployed into revenue generating assets. We believe that the temporary absence of future cash flows from communities sold will not have a material impact on our ability to fund future liquidity and capital resource needs.

Unconsolidated Real Estate Investments and Off-Balance Sheet Arrangements

Unconsolidated Investments

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

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 an equity investment of $19,737,000 (net of distributions), representing a 31.3% combined general partner and limited partner equity interest. Upon achievement of a threshold return, we have a right to incentive distributions for our promoted interest representing the first 20.0% of further Fund II distributions, which are in addition to our share of the remaining 80.0% of distributions. During 2016, we recognized income of $7,985,000 for our promoted interest. Fund II served as the exclusive vehicle for acquiring apartment communities from its formation in 2008 through the close of its investment period in August 2011. Fund II has a term that expires in August 2020, assuming the exercise of two, one-year extension options.

During 2016, Fund II sold three communities containing an aggregate of 1,514 apartment homes for an aggregate sales price of $382,950,000. Our share of the total gain in accordance with GAAP was $41,501,000. In conjunction with the disposition of these communities, Fund II repaid $156,248,000 of related secured indebtedness in advance of the scheduled maturity dates, which resulted in charges for prepayment penalties and write-offs of deferred financing costs, of which our portion was $1,768,000.

The U.S. Fund has six institutional investors, including us. We are the general partner of the U.S. Fund and, excluding costs incurred in excess of our equity in the underlying net assets of the U.S. Fund, we have an equity investment of $49,693,000 (net of distributions), representing a 28.6% combined equity interest. The U.S. Fund was formed in July 2011 and is fully invested. The U.S. Fund has a term that expires in July 2023, assuming the exercise of two, one-year extension options.

During 2016, the U.S. Fund sold two communities containing an aggregate of 461 apartment homes for an aggregate sales price of $229,300,000. Our share of the total gain in accordance with GAAP was $16,568,000. In conjunction with the disposition of these communities, the U.S. Fund repaid $94,822,000 of related secured indebtedness in advance of the scheduled maturity dates, which resulted in charges for prepayment penalties and write-offs of deferred financing costs, of which our portion was $2,003,000.

The AC JV has four institutional investors, including us. Excluding costs incurred in excess of our equity in the underlying net assets of the AC JV, we have an equity investment of $50,674,000 (net of distributions), representing a 20.0% equity interest. The AC JV was formed in 2011.

During 2016, we entered into a joint venture to develop, own, and operate AVA North Point, an apartment community located in Cambridge, MA, which is currently under construction and expected to contain 265 apartment homes upon completion. We own a 55.0% interest in the venture, and the venture partner owns the remaining 45.0% interest. AVA North Point is the third phase of a master planned development, the other phases of which are owned through the AC JV. During 2016, we provided the partners of the AC JV the opportunity to acquire the AVA North Point land parcel we owned as required in the ROFO provisions for the AC JV. After certain partners of the AC JV declined to participate, we entered into the new joint venture and sold the land parcel to the venture in exchange for a cash payment and a capital account credit, and we are overseeing the development in exchange for a developer fee. Upon sale of the land parcel, we recognized a gain of $10,621,000.

In May 2016, we entered into a joint venture agreement to facilitate the acquisition of Avalon Clarendon, located in Arlington, VA. Avalon Clarendon is part of a mixed-use development containing residential, retail, office and public parking. We contributed $120,300,000 to the venture for our share of the purchase price. We had shared control of the overall venture, but had all of the rights and obligations associated with the residential component of Avalon Clarendon, containing 300 apartment homes. The joint venture partner had all of the rights and obligations associated with the retail, office and public parking components of the mixed-use development. During September 2016, we established separate legal ownership of the residential and retail, office and public parking components of the venture with our venture partner, and we retained all of the rights and obligations associated with the residential component. After this legal separation, beginning October 2016, we began reporting the operating results of Avalon Clarendon as part of our consolidated operations. In conjunction with the consolidation of Avalon Clarendon, we recorded the consolidated assets at fair value, resulting in a gain of $4,322,000 for the difference between the fair value of Avalon Clarendon and our equity interest at the date of consolidation of $115,848,000, primarily attributable to depreciation recognized during the period the community was owned in the joint venture.

As part of the Archstone Acquisition we entered into a limited liability company agreement with Equity Residential, through which we assumed obligations of Archstone in the form of preferred interests, some of which are governed by tax protection arrangements (the “Legacy JV”). We have a 40.0% interest in the Legacy JV. During the years ended December 31, 2016, 2015 and 2014, the Legacy JV redeemed certain of the preferred interests and paid accrued dividends, of which our portion was $1,960,000, $14,410,000 and $6,300,000, respectively. At December 31, 2016, the remaining preferred interests had an aggregate liquidation value of $39,921,000, our share of which is included in accrued expenses and other liabilities in the accompanying Consolidated Balance Sheets presented elsewhere in this report.

As of December 31, 2016, we had investments in the following unconsolidated real estate accounted for under the equity method of accounting excluding development joint ventures. Refer to Note 5, “Investments in Real Estate Entities,” of the Consolidated Financial Statements included 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. For ventures holding operating apartment communities as of December 31, 2016, detail of the real estate and associated funding underlying our unconsolidated investments is presented in the following table (dollars in thousands).

Off-Balance Sheet Arrangements

In addition to our investment interests in consolidated and 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 included elsewhere in this report.

We have not guaranteed the debt of our unconsolidated real estate entities, as referenced in the table above, nor do we have any obligation to fund this debt should the unconsolidated real estate entities be unable to do so. In the future, in the event the unconsolidated real estate entities 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 the unconsolidated real estate entities and/or our returns by providing time for performance to improve.

With respect to Fund II, each individual mortgage loan was made to a special purpose, single asset subsidiary of Fund II. 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 Fund II could also have obligations with respect to the mortgage loan. In no event do the mortgage loans provide for recourse against investors in Fund II, including against us or our wholly-owned subsidiaries that invest in Fund II. A default by Fund II or a Fund II 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 Fund II or a subsidiary of Fund II were unable to meet its obligations under a loan, the value of our investment in Fund II would likely decline. If a Fund II subsidiary or Fund II 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 Fund II 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 II asset).

There are no other material 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.

(1)	Includes land leases expiring between October 2026 and March 2142. Amounts do not include any adjustment for purchase options available under the land leases.


(2)	Aggregate capital lease payments include $27,374 in interest costs.

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. Short-term leases generally minimize our risk from the adverse effect of inflation, although these leases generally permit residents to leave at the end of the lease term and therefore expose us to the effect of a decline in market rents. Similarly, in a deflationary rent environment, we may be exposed to declining rents more quickly under these shorter-term leases.

Federal Income Tax Law Changes and Updates

The following discussion updates the disclosures under “Federal Income Tax Considerations and Consequences of Your Investment” in the prospectus dated February 19, 2015 contained in our Registration Statement on Form S-3 filed with the SEC on February 19, 2015.

The discussion in the last sentence under “Federal Income Tax Considerations and Consequences of Your Investment-Other U.S. Federal Income Tax Withholding and Reporting Requirements” on page 61 is replaced with the following sentence: ‘‘Withholding under this legislation will apply after December 31, 2018 with respect to the gross proceeds of a disposition of property that can produce U.S. source interest or dividends and currently applies with respect to other withholdable payments.’’

The discussion under “Federal Income Tax Considerations and Consequences of Your Investment-Taxation of AvalonBay as a REIT-Ownership of Partnership Interests by a REIT” on page 47 is supplemented by inserting the paragraph below at the end of that subsection:

Under the Code, a partnership that is not treated as a corporation under the publicly traded partnership rules generally is not subject to U.S. federal income tax; instead, each partner is allocated its distributive share of the partnership’s items of income, gain, loss, deduction and credit and is required to take such items into account in determining the partner’s income. However, a recent law change enacted under the Bipartisan Budget Act of 2015, effective for taxable years beginning after December 31, 2017, requires the partnership to pay the hypothetical increase in partner-level taxes (including interest and penalties) resulting from an adjustment of partnership tax items on audit or in other tax proceedings, unless the partnership elects an alternative method under which the taxes resulting from the adjustment (and interest and penalties) are assessed at the partner level. Many uncertainties remain as to the application of these rules, including the application of the alternative method to partners that are REITs, and the impact they will have on us. However, it is possible, that partnerships in which we invest may be subject to U.S. federal income tax, interest and penalties in the event of a U.S. federal income tax audit as a result of these law changes.

Recent legislation modifies several of the REIT rules discussed in the prospectus. The “Protecting Americans from Tax Hikes Act of 2015” (the “Act”) was enacted on December 18, 2015 and contains several provisions pertaining to REIT qualification and taxation. Some of these implicate certain tax-related disclosure contained in the prospectus and are briefly summarized below:


•	For taxable years beginning after December 31, 2015, the Act expands the exclusion of certain hedging income from the REIT gross income tests to include income from hedges of previously acquired hedges that a REIT entered to manage risk associated with liabilities or property that have been extinguished or disposed.

•

For taxable years beginning before January 1, 2018, no more than 25% of the value of our assets may consist of stock or securities of one or more taxable REIT subsidiaries. For taxable years beginning after December 31, 2017, the Act reduces this limit to 20%. At this time, the securities we own in our taxable REIT subsidiaries do not, in the aggregate, exceed 20% of the total value of our assets.

•

For taxable years beginning after December 31, 2015, for purposes of the REIT asset tests, the Act provides that debt instruments issued by publicly offered REITs will constitute “real estate assets.” However, unless such a debt instrument is secured by a mortgage or otherwise would have qualified as a real estate asset under prior law, (i) interest income and gain from such a debt instrument is not qualifying income for purposes of the 75% gross income test and (ii) all such debt instruments may represent no more than 25% of the value of our total assets.


•	For taxable years beginning after December 31, 2015, certain obligations secured by a mortgage on both real property and personal property will be treated as a qualifying real estate asset and give rise to qualifying income for purposes of the 75% gross income test if the fair market value of such personal property does not exceed 15% of the total fair market value of all such property.


•	A 100% excise tax is imposed on “redetermined TRS service income,” which is income of a taxable REIT subsidiary attributable to services provided to, or on behalf of its associated REIT and which would otherwise be increased on distribution, apportionment, or allocation under Section 482 of the Code.


•	For distributions made in taxable years beginning after December 31, 2014, the preferential dividend rules no longer to apply to us.

Table of Contents


•	Additional exceptions to the rules under the Foreign Investment in Real Property Act (“FIRPTA”) were introduced for non-U.S. persons that constitute “qualified shareholders” (within the meaning of Section 897(k)(3) of the Code) or “qualified foreign pension funds” (within the meaning of Section 897(l)(2) of the Code).


•	After February 16, 2016, the FIRPTA withholding rate under Section 1445 of the Code for dispositions of U.S. real property interests is increased from 10% to 15%.


•	The Act increases from 5% to 10% the maximum stock ownership of the REIT that a non-U.S. shareholder may hold to avail itself of the FIRPTA exception for shares regularly traded on an established securities market.


•	For assets we acquired from a C corporation in a carry-over basis transaction, the Act, in conjunction with recently promulgated Treasury Regulations, reduces the recognition period during which we could be subject to corporate tax on any built-in gains recognized on the sale of such assets from 10 years to 5 years.

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;


•	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;


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


•	our qualification as a REIT under the Internal Revenue 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 the potential impacts from current economic conditions;


•	trends affecting our financial condition or results of operations; and


•	the impact of legal proceedings relating to the Edgewater casualty loss and related matters, including liability to third parties resulting therefrom.

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. 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. You should carefully review the discussion under Item 1A. “Risk Factors” in this report for further discussion of risks associated with 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;

Table of Contents


•	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;


•	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 II, the U.S. Fund, the AC JV or the REIT vehicles that are used with each respective joint venture;


•	we may be unsuccessful in managing changes in our portfolio composition; and


•	our expectations, estimates and assumptions as of the date of this filing regarding the outcome of investigations and/or legal proceedings resulting from the Edgewater casualty loss, are subject to change.

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, Basis of Presentation and Significant Accounting Policies,” of our Consolidated Financial Statements.

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, excluding the Residual JV, at December 31, 2016, our assets would have increased by $827,020,000 and our liabilities would have increased by $706,110,000. 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 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. Capitalization begins when we determine that development of a future asset is probable and continues 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 apartment homes out of service when significant renovation of the common area has begun and continue until the redevelopment is completed, or (ii) when an apartment home is taken out of service for redevelopment and continue 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 in earnings as they accrue. We defer external costs associated with originating new leases, recognizing the impact of these costs in earnings over the term of the lease.

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 $45,201,000, $43,943,000 and $37,433,000 for 2016, 2015 and 2014, 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.

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 2016 our development activities decreased by 10%, and there were no corresponding decrease in our indirect project costs, our costs charged to expense would have increased by $4,520,000.

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, 2016 would have decreased by $4,018,000.

Abandoned Pursuit Costs & Asset Impairment

We evaluate our real estate and other long-lived assets for impairment when potential indicators of impairment exist. 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. We assess land held for development for impairment if our intent changes with respect to the development of the land. We 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.

We expense costs related to abandoned pursuits, which include the abandonment of Development Rights and disposition pursuits. These costs can vary greatly, and the costs incurred in any given period may be significantly different in future years.

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” in 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 Internal Revenue 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 2016, our net income would have decreased by approximately $415,669,000.

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

The adoption of ASU 2017-01, as discussed in Note 1, “Organization, Basis of Presentation and Significant Accounting Policies,” of the Consolidated Financial Statements set forth in Item 8 of this report, has impacted our accounting framework for the acquisition of investments in real estate. Prior to adoption of ASU 2017-01 on October 1, 2016, we accounted for acquisitions of investments in real estate in accordance with the authoritative guidance for the initial measurement, which required 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, buildings, furniture, fixtures and equipment and identified intangible assets and liabilities, consisting of the value of above or below market leases and in-place leases. In making estimates of fair values for purposes of allocating purchase price, we utilized various sources, including our own analysis of recently acquired and existing comparable properties in our portfolio and other market data. Consideration for acquisitions is typically in the form of cash unless otherwise disclosed. We expensed all costs incurred related to acquisitions of operating communities. Subsequent to adoption of ASU 2017-01, we assess each acquisition of an operating community to determine if it meets the definition of a business or if it qualifies as an asset acquisition. We expect that acquisitions of individual operating communities will generally be viewed as asset acquisitions, and result in the capitalization of acquisition costs, and the allocation of purchase price to the assets acquired and liabilities assumed based on the relative fair value of the respective assets and liabilities.

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 and unsecured notes 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. During 2015 and 2016, we entered into $1,200,000,000 of forward interest rate swap agreements to reduce the impact of variability in interest rates on a portion of our expected debt issuance activity in 2016 and 2017. In May 2016, we settled $400,000,000 of the aggregate outstanding swaps in conjunction with our May 2016 unsecured note issuance. In addition, we have interest rate caps that serve to 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.

As of December 31, 2016 and 2015, we had $1,208,262,000 and $1,345,182,000, respectively, in variable rate debt outstanding, with no amounts outstanding under our Credit Facility. If interest rates on the variable rate debt had been 100 basis points higher throughout 2016 and 2015, our annual interest costs would have increased by approximately $12,901,000 and $14,492,000, respectively, based on balances outstanding during the applicable years.

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, 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 quoted market prices for our unsecured notes or a discounted cash flow model for our secured notes, considering our current market yields, which impacts the fair value of our aggregate indebtedness. Debt securities and notes payable (including amounts outstanding under our Credit Facility) with an aggregate principal amount outstanding of $7,076,758,000 at December 31, 2016 had an estimated aggregate fair value of $6,963,089,000 at December 31, 2016. Contractual fixed rate debt represented $5,926,025,000 of the fair value at December 31, 2016. If interest rates had been 100 basis points higher as of December 31, 2016, the fair value of this fixed rate debt would have decreased by approximately $334,076,000.

ITEM 9A. CONTROLS AND PROCEDURES

(a)

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, 2016 and 2015, and the related consolidated statements of comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2016. 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, 2016 and 2015, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2016, 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.

As discussed in Note 1 to the consolidated financial statements, the Company changed its method for reporting discontinued operations effective January 1, 2014.

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, 2016, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 24, 2017 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, 2016, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (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, 2016, 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, 2016 and 2015, and the related consolidated statements of comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2016 of AvalonBay Communities, Inc. and our report dated February 24, 2017 expressed an unqualified opinion thereon.

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 qualify for consolidation. All significant intercompany balances and transactions have been eliminated in consolidation.

The Company accounts for joint venture entities and subsidiary partnerships in accordance with the consolidation guidance. The Company evaluates the partnership of each joint venture entity and determines first whether to follow the variable interest entity (“VIE”) or the voting interest entity (“VOE”) model. Once the appropriate consolidation model is identified, the Company then evaluates whether it should consolidate the venture. Under the VIE model, the Company consolidates an investment when it has control to direct the activities of the venture and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Under the VOE model, the Company consolidates an investment when 1) it controls the investment through ownership of a majority voting interest if the investment is not a limited partnership or 2) it controls the investment through its ability to remove the other partners in the investment, at its discretion, when the investment is a limited partnership.

The Company generally uses the equity method of accounting for its investment in joint ventures, under all other potential scenarios, including where the Company holds a noncontrolling limited partner interest in a joint venture. Any investment in excess of the Company's cost basis at acquisition or formation of an equity method venture, will be recorded as a component of the Company's investment in the joint venture and recognized over the life of the underlying fixed assets of the venture as a reduction to its equity in income from the 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 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 records a charge to income for outstanding receivables greater than 90 days past due as a component of operating expenses, excluding property taxes on the accompanying Consolidated Statements of Comprehensive Income.

The Company accounts for the sale of real estate assets and any 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 does not have significant continuing involvement.

Real Estate

Operating real estate assets are stated at cost and consist of land and improvements, 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 existing asset and that will benefit the Company for periods greater than a year, are capitalized. Expenditures for maintenance and repairs are charged to expense as incurred. 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 land parcels improved with operating real estate, for which the Company intends to pursue development, the Company generally manages 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 land parcels in excess of any incremental costs are recorded as a reduction of total capitalized costs of the respective Development Right and not as part of net income.

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 in earnings as incurred. The Company defers external costs associated with originating new leases, recognizing the impact of these costs in earnings over the term of the lease.

The adoption of ASU 2017-01 is expected to impact the Company's accounting framework for the acquisition of operating communities. Prior to adoption of ASU 2017-01 on October 1, 2016, the acquisition of an operating community was viewed as an acquisition of a business, and the Company identified and recorded each asset acquired and liability assumed in such transaction at its estimated fair value at the date of acquisition. The purchase price allocation to tangible assets, such as land and improvements, buildings and improvements, and furniture, fixtures and equipment, and the in-place lease intangible assets, was reflected in real estate assets and depreciated over their estimated useful lives. Any purchase price allocation to intangible assets, other than in-place lease intangibles, was included in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets and amortized over the term of the acquired intangible asset. The Company expensed all costs incurred related to acquisitions of operating communities. The Company valued land based on a market approach, looking to recent sales of similar properties, adjusting for differences due to location, the state of entitlement as well as the shape and size of the parcel. Improvements to land were valued using a replacement cost approach and consider the structures and amenities included for the communities. The approach applied industry standard replacement costs adjusted for geographic specific considerations and reduced by estimated depreciation. The value for furniture, fixtures and equipment was also determined based on a replacement cost approach, considering costs for both items in the apartment homes as well as common areas and was adjusted for estimated depreciation. The fair value of buildings acquired was estimated using the replacement cost approach, assuming the buildings were vacant at acquisition. The replacement cost approach considered the composition of structures acquired, adjusted for an estimate of depreciation. The estimate of depreciation was made considering industry standard information, depreciation curves for the identified asset classes and estimated useful life of the acquired property. The value of the acquired lease-related intangibles considered the estimated cost of leasing the apartment homes as if the acquired building(s) were vacant, as well as the value of the current leases relative to market-rate leases. The in-place lease value was determined using an average total lease-up time, the number of apartment homes and net revenues generated during the lease-up time. The lease-up period for an apartment community was assumed to be 12 months to achieve stabilized occupancy. Net revenues used market rent considering actual leasing and industry rental rate data. The value of current leases relative to a market-rate lease was based on market rents obtained for market comparables, and considered a market derived discount rate. Given the significance of unobservable inputs used in the value of real estate assets acquired, the Company classified them as Level 3 prices in the fair value hierarchy. Consideration for acquisitions is typically in the form of cash unless otherwise disclosed.

F-10

Table of Contents

Subsequent to adoption of ASU 2017-01, the Company assesses each acquisition of an operating community to determine if it meets the definition of a business or if it qualifies as an asset acquisition. The Company expects that acquisitions of individual operating communities will generally be viewed as asset acquisitions, and result in the capitalization of acquisition costs, and the allocation of purchase price to the assets acquired and liabilities assumed, based on the relative fair value of the respective assets and liabilities.

Depreciation is calculated on buildings and improvements using the straight-line method over their estimated useful lives, which range from seven to 30 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, 2016 and 2015, 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 2013 through 2015.

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 its 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 exemption from 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 did not incur any charges or receive refunds of excise taxes related to the years ended December 31, 2016, 2015 and 2014. In addition, taxable income from non-REIT activities performed through taxable REIT subsidiaries (“TRS”) is subject to federal, state and local income taxes. The Company incurred income tax expense of $305,000, $1,483,000 and $9,368,000 in 2016, 2015 and 2014, respectively, associated primarily with activities transacted through a TRS.

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 related to unsecured notes was $14,008,000 and $11,995,000 as of December 31, 2016 and 2015, respectively, and related to mortgage notes payable was $10,562,000 and $12,315,000 as of December 31, 2016 and 2015, respectively. Deferred financing costs, except for costs associated with line-of-credit arrangements, are presented as a direct deduction from the related debt liability. Accumulated amortization of deferred financing costs related to the Company's Credit Facility was $6,490,000 and $4,967,000 as of December 31, 2016 and 2015, respectively, and was included in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets.

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 principal reserve funds that are restricted for the repayment of specified secured financing. The majority of the Company's cash, cash equivalents and cash in escrow are held at major commercial banks.

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 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 earnings per share (“EPS”). Both the unvested restricted shares and other potentially dilutive common shares, and the related impact to earnings, are considered when calculating earnings per share on a diluted basis. The Company's earnings per common share are determined as follows (dollars in thousands, except per share data):

All options to purchase shares of common stock outstanding as of December 31, 2016, 2015 and 2014 are included in the computation of diluted earnings per share.

The Company is required to estimate the forfeiture of stock options and recognize 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, 2016 was 0.8% and is based on the average forfeiture activity over a period equal to the estimated life of the stock options. The application of estimated forfeitures did not materially impact compensation expense for the years ended December 31, 2016, 2015 and 2014. As discussed under "Recently Issued and Adopted Accounting Standards," the Company will adopt the provision of ASU 2016-09 and recognize forfeitures as they occur beginning in 2017.

Abandoned Pursuit Costs and Impairment of Long-Lived Assets

The Company capitalizes pre-development costs incurred in pursuit of new development opportunities for which the Company currently believes future development is probable (“Development Rights”). 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 expensed. The Company expensed costs related to the abandonment of Development Rights, as well as costs incurred in pursuing the acquisition of assets or costs incurred pursuing the disposition of assets for which such acquisition and disposition activity did not occur, in the amounts of $4,183,000, $3,016,000 and $3,964,000 during the years ended December 31, 2016, 2015 and 2014, respectively. These costs are included in expensed acquisition, development and other pursuit costs, net of recoveries 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.

Table of Contents

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 or long-lived asset may not be recoverable, the Company assesses its recoverability by comparing the carrying amount of the property or long-lived asset 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 or long-lived asset. Based on periodic tests of recoverability of long-lived assets, for the years ended December 31, 2016, 2015 and 2014, the Company did not recognize any impairment losses for wholly-owned operating real estate assets, and did not record any impairment losses other than those related to the impairment on land held for investment and casualty gains and losses from property damage in 2016 and 2015 discussed below.

The Company assesses its portfolio of land held for both development and investment for impairment if the intent of the Company changes with respect to either the development of, or the expected holding period for, the land. During the year ended December 31, 2016, the Company recognized $10,500,000 of aggregate impairment charges related to three ancillary land parcels for which the Company has either sold or intends to sell. These charges were determined as the excess of the Company's carrying basis over the expected sales price for each parcel, and is included in casualty and impairment (gain) loss, net on the accompanying Consolidated Statements of Comprehensive Income. The Company did not recognize any material impairment charges on its investment in land during the years ended December 31, 2015 and 2014.

The Company evaluates its unconsolidated investments for other than temporary impairment, considering both the extent and amount by which the carrying value of the investment exceeds the fair value, and the Company’s intent and ability to hold the investment to recover its carrying value. The Company also evaluates its proportionate share of any impairment of assets held by unconsolidated investments. There were no other than temporary impairment losses recognized by any of the Company's investments in unconsolidated real estate entities during the years ended December 31, 2016, 2015 or 2014.

Casualty Gains and Losses

In January 2015, a fire occurred at the Company's Avalon at Edgewater apartment community located in Edgewater, NJ. Edgewater consisted of two residential buildings. One building, containing 240 apartment homes, was destroyed. The second building, containing 168 apartment homes, suffered minimal damage and has been repaired. See Note 7, “Commitments and Contingencies,” for discussion of the related legal matters.

During the year ended December 31, 2016, the Company reached a final insurance settlement for the Company's property damage and lost income for the Edgewater casualty loss, for which it received aggregate insurance proceeds for Edgewater of $73,150,000, after self-insurance and deductibles, as discussed below.

During the year ended December 31, 2015, the Company received $44,142,000 in insurance proceeds, which were partially offset by casualty charges of $21,844,000 to write off the net book value of the building destroyed by the fire at Edgewater, and $6,760,000 to record demolition and additional incident expenses, resulting in a net casualty gain of $15,538,000. During the year ended December 31, 2016, the Company received the final $29,008,000 of insurance proceeds, of which $8,702,000 was recognized as an additional net casualty gain and $20,306,000 as business interruption insurance proceeds. The Company reported the net casualty gains from each of the respective years as casualty and impairment (gain) loss, net on the accompanying Consolidated Statements of Comprehensive Income, and reported the business interruption insurance proceeds as a component of rental and other income on the accompanying Consolidated Statements of Comprehensive Income.

During the year ended December 31, 2015, several of the Company's communities in its Northeast markets incurred property and casualty damages from severe winter storms, for which the Company recorded an impairment due to a casualty loss of $4,195,000. During the year ended December 31, 2016, the Company recorded a net casualty gain related to the 2015 severe winter storms of $5,732,000, which is comprised of $8,493,000 in third-party insurance proceeds received, partially offset by incremental costs of $2,761,000. These amounts are included in casualty and impairment (gain) loss, net on the accompanying Consolidated Statements of Comprehensive Income.

The Company did not incur a casualty loss in 2014.

F-14

Table of Contents

A casualty loss may also result in lost operating income from one or more communities that is covered by the Company’s business interruption insurance policies. The Company recognizes income for amounts received under its business interruption insurance policies as a component of rental and other income in the Consolidated Statements of Comprehensive Income. Revenue is recognized upon resolution of all contingencies related to the receipt, typically upon written confirmation by the insurer or receipt of the actual proceeds. The Company recognized $20,564,000, of which $20,306,000 was related to the Edgewater casualty loss, $1,509,000 and $2,494,000 in income related business interruption insurance proceeds for the years ended December 31, 2016, 2015 and 2014, respectively.

Assets Held for Sale and 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 accompanying Consolidated Statements of Comprehensive Income. 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. Upon the classification of an asset as held for sale, no further depreciation is recorded. Subsequent to the adoption of ASU 2014-08 on January 1, 2014, as discussed under "Recently Issued and Adopted Accounting Standards," disposals representing a strategic shift in operations (e.g., a disposal of a major geographic area, a major line of business or a major equity method investment) will be presented as discontinued operations, and 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 two ancillary land parcels that qualified as held for sale presentation at December 31, 2016.

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 shares of the Company's common stock, 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 11, “Fair Value.”

Derivative Instruments and Hedging Activities

The Company enters into interest rate swap and interest rate cap agreements (collectively, “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 Hedging Derivative transactions for trading or other speculative purposes. The Company assesses the effectiveness of qualifying cash flow and fair value hedges, both at inception and on an on-going basis. Hedge ineffectiveness is reported as a component of general and administrative expenses. The fair values of Hedging Derivatives that are in an asset position are recorded in prepaid expenses and other assets. The fair value of Hedging Derivatives that are in a liability position are included in accrued expenses and other liabilities. The Company does not present or disclose the fair value of Hedging Derivatives on a net basis. Fair value changes for derivatives that are not in qualifying hedge relationships are reported as a component of interest expense, net. For the Hedging 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 Hedging Derivatives in other comprehensive income (loss). Amounts recorded in other comprehensive income (loss) will be reclassified into earnings in the periods in which earnings are affected by the hedged cash flow. The effective portion of the change in fair value of the Hedging Derivatives that the Company has determined qualified as effective fair value hedges is reported as an adjustment to the carrying amount of the corresponding debt being hedged. See Note 11, “Fair Value,” for further discussion of derivative financial instruments.

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' notes to financial statements to conform to current year presentations as a result of changes in held for sale classification and disposition activity.

Recently Issued and Adopted Accounting Standards

In January 2017, the FASB issued ASU 2017-01-Business Combinations (Topic 805): Clarifying the Definition of a Business, which changes the definition of a business to assist in determining when a set of transferred assets is a business. The guidance states that if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, the transaction is an asset acquisition and not a business combination. If the fair value of the gross assets acquired is not concentrated into a single asset or group of similar assets, the acquired assets are viewed as a business combination only if they include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output. The guidance will be effective in the first quarter of 2018 and allows for early adoption of transactions that have not been reported in financial statements that have been issued or made available for issuance. The Company adopted the guidance as of October 1, 2016 and did not acquire any businesses during the fourth quarter of 2016. The adoption of the standard did not have a material effect on the Company’s financial position or results of operations.

In November 2016, the FASB issued ASU 2016-18-Statement of Cash Flows (Topic 230): Restricted Cash, which requires statements of cash flows to explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new standard requires a retrospective approach. The guidance will be effective in the first quarter of 2018 and allows for early adoption. The Company is assessing whether the new standard will have a material effect on its financial position or results of operations.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU addresses eight specific cash flow issues including debt prepayment or debt extinguishment costs, proceeds from the settlement of insurance claims, distributions received from equity method investees and separately identifiable cash flows and application of the predominance principle. The new standard requires a retrospective approach. The guidance will be effective in the first quarter of 2018 and allows for early adoption. The Company will adopt the new standard effective January 1, 2017, and does not anticipate that the new standard will have a material effect on its financial position or results of operations.

In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of share-based payment transactions, including income tax consequences, classification of awards as equity or liability, statement of cash flows classification and policy election options for forfeitures. Upon adoption of the standard, the Company will elect to account for forfeitures when they occur instead of estimating the forfeitures. The Company will adopt this guidance effective January 1, 2017, using the modified retrospective approach. The Company does not anticipate that the new standard to have a material effect on its financial position or results of operations.

In February 2016, the FASB issued ASU 2016-02, Leases, amending the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. The guidance will be effective in the first quarter of 2019 and allows for early adoption. The new standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief.

F-16

Table of Contents

ASU 2016-02 provides for transition relief, which includes not electing to (i) reassess whether any expired or existing contract is a lease or contains a lease, (ii) reassess the lease classification of any expired or existing leases and (iii) expense any capitalized initial direct costs for any existing leases. The Company anticipates adoption of the standard to have a material impact on its financial position and results of operations resulting from the recognition of the right to use asset and corresponding lease obligation for its long-term ground leases, currently accounted for as operating leases. The Company will continue to assess the impact of the new standard.

In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which requires management to assess an entity’s ability to continue as a going concern. The standard was effective in the fourth quarter of 2016 for the Company. The standard did not have a material effect on the Company’s financial position or results of operations.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers and in August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers-Deferral of the Effective Date, which defers the effective date of the new revenue recognition standard until the first quarter of 2018. Subsequently, the FASB has issued multiple ASUs clarifying ASU 2014-09 and ASU 2015-14.

Under the new standard, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectability is probable. Revenue is generally recognized net of allowances and any taxes collected from customers and subsequently remitted to governmental authorities. The majority of the Company’s revenue is derived from rental income, which is scoped out from this standard and will be accounted for under ASU 2016-02, Leases, discussed above. The Company's other revenue streams, which are being evaluated under this ASU, include but are not limited to management fees, other income from residents determined not to be within the scope of ASU 2016-02 and gains and losses from real estate dispositions. The Company will continue to assess the impact of the new standard and anticipates adoption as of January 1, 2018 using the modified retrospective approach.

In April 2014, the FASB issued ASU 2014-08, guidance updating the accounting and reporting for discontinued operations, under which only disposals representing a strategic shift in operations (e.g., a disposal of a major geographic area, a major line of business or a major equity method investment) will be presented as discontinued operations. The standard also requires expanded disclosures about dispositions that will provide financial statement users with more information about the assets, liabilities, income and expenses of discontinued operations, as well as disposals of a significant part of an entity that does not qualify for discontinued operations reporting. The standard was effective in the first quarter of 2015 and the Company adopted the guidance as of January 1, 2014.

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 $78,872,000, $79,834,000 and $69,961,000 for years ended December 31, 2016, 2015 and 2014, respectively.

•	In October 2016, the Company issued $350,000,000 principal amount of unsecured notes in a public offering under its existing shelf registration statement for net proceeds of approximately $345,520,000. The notes mature in October 2046 and were issued at a 3.90% coupon interest rate.


•	In November 2016, the Company repaid $250,000,000 principal amount of its 5.70% coupon unsecured notes in advance of its March 2017 scheduled maturity, recognizing a charge of $4,614,000, consisting of a prepayment penalty of $4,403,000 and the write-off of deferred financing costs of $211,000.

In January 2016, the Company extended the maturity of its revolving variable rate unsecured credit facility (the “Credit Facility”) from April 2017 to April 2020, and amended other provisions in the Credit Facility. In addition, 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 from $1,300,000,000 to $1,500,000,000 (the “Credit Facility Increase”). The Company may further extend the term for up to nine months, provided the Company is not in default and upon payment of a $1,500,000 extension fee. In connection with the Credit Facility Increase, the applicable margin over reference rates used to determine the applicable interest rates on the Company's 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 the Company's unsecured notes and on a maturity schedule selected by the Company. The current stated pricing is LIBOR plus 0.825% per annum (1.60% at December 31, 2016), assuming a one month borrowing rate. The stated spread over LIBOR can vary from LIBOR plus 0.80% to LIBOR plus 1.55% based on the Company's 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 Credit Facility Increase, the annual facility fee was also amended to lower the fee to 0.125% from 0.15%, resulting in a fee of approximately $1,875,000 annually based on the $1,500,000,000 facility size and based on the Company's current credit rating.

The Company had no borrowings outstanding under the Credit Facility and had $46,711,000 and $43,049,000 outstanding in letters of credit that reduced the borrowing capacity as of December 31, 2016 and 2015, respectively.

In the aggregate, secured notes payable mature at various dates from February 2017 through July 2066, and are secured by certain apartment communities (with a net carrying value of $3,460,572,000, excluding communities classified as held for sale, as of December 31, 2016).

As of December 31, 2016, the Company has guaranteed a $100,000,000 mortgage note payable held by a wholly-owned subsidiary; such mortgage note payable is consolidated for financial reporting purposes. The weighted average interest rate of the Company's fixed rate mortgage notes payable (conventional and tax-exempt) was 4.4% and 4.6% at December 31, 2016 and 2015, respectively. The weighted average interest rate of the Company's variable rate mortgage notes payable (conventional and tax exempt), the Term Loan and its Credit Facility, including the effect of certain financing related fees, was 2.3% and 1.8% at December 31, 2016 and 2015, respectively.

The Company's unsecured notes are redeemable at the Company's 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 20 and 45 basis points depending on the specific series of unsecured notes, plus accrued and unpaid interest to the redemption date. The indenture under which the Company's unsecured notes were issued, the Company's Credit Facility agreement and the Company's Term Loan agreement contain 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, 2016.

Table of Contents

In December 2015, the Company commenced a fourth continuous equity program (“CEP IV”) under which the Company may sell up to $1,000,000,000 of its common stock from time to time. 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 IV, the Company engaged sales agents who will receive compensation of up to 2.0% of the gross sales price for shares sold. CEP IV also allows the Company to enter into forward sale agreements up to $1,000,000,000 in aggregate sales price of its common stock. The Company will physically settle each forward sale agreement on one or more dates specified by the Company on or prior to the maturity date of that particular forward sale agreement, in which case the Company will expect to receive aggregate net cash proceeds at settlement equal to the number of shares underlying the particular forward agreement multiplied by the relevant forward sale price. However, the Company may also elect to cash settle or net share settle a forward sale agreement. In connection with each forward sale agreement, the Company will pay the relevant forward seller, in the form of a reduced initial forward sale price, commission of up to 2.0% of the sales prices of all borrowed shares of common stock sold. In 2016, the Company had no sales under the program and did not enter into any forward sale agreements.

5. Investments in Real Estate Entities

Investments in Unconsolidated Real Estate Entities

The Company accounts for its investments in unconsolidated real estate entities under the equity method of accounting, as discussed in Note 1, “Organization, Basis of Presentation and Significant Accounting Policies,” 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, 2016, the Company had investments in the following real estate entities:

•

AvalonBay Value Added Fund II, L.P. (“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 at December 31, 2016, excluding costs incurred in excess of equity in the underlying net assets of Fund II, the Company has an equity investment of $19,737,000 (net of distributions), representing a 31.3% combined general partner and limited partner equity interest.

During 2016, Fund II sold three communities containing an aggregate of 1,514 apartment homes:


•	Eaves Rancho San Diego, located in El Cajon, CA, for $158,000,000,


•	Eaves Tustin, located in Tustin, CA, for $163,550,000, and


•	Eaves Rockville, located in Rockville, MD, for $61,400,000.

The Company's proportionate share of the gain in accordance with GAAP for the three dispositions was $41,501,000. In conjunction with the disposition of these communities, Fund II repaid $156,248,000 of related secured indebtedness in advance of the scheduled maturity dates. This resulted in charges for prepayment penalties and write-offs of deferred financing costs, of which the Company’s portion was $1,768,000 and was reported as a reduction of equity in income of unconsolidated real estate entities on the accompanying Consolidated Statements of Comprehensive Income.

The Company has an equity interest of 31.3% in Fund II, and upon achievement of a threshold return the Company has a right to incentive distributions for its promoted interest representing the first 20.0% of further Fund II distributions, which are in addition to its share of the remaining 80.0% of distributions. During the year ended December 31, 2016, the Company recognized income of $7,985,000 for its promoted interest, which is reported as a component of equity in income of unconsolidated real estate entities on the accompanying Consolidated Statements of Comprehensive Income.

Subsidiaries of Fund II have four loans secured by individual assets with aggregate amounts outstanding of $128,008,000, with maturity dates that vary from November 2017 to April 2019. The mortgage loans are payable by the subsidiaries of Fund II from 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.

Residual JV—Through subsidiaries, the Company and Equity Residential entered into three limited liability company agreements (collectively, the “Residual JV”) through which the Company and Equity Residential acquired (i) certain assets of Archstone that the Company and Equity Residential have substantially divested (the “Residual Assets”), and (ii) various liabilities of Archstone that the Company and Equity Residential agreed to assume in conjunction with the Archstone Acquisition (the “Residual Liabilities”). The Residual Assets included a 20.0% interest in Lake Mendota Investments, LLC and Subsidiaries (“SWIB”), a joint venture which disposed the last of its communities in 2015, as well as various licenses, insurance policies, contracts, office leases and other miscellaneous assets.

The Residual Liabilities include most existing or future litigation and claims related to Archstone’s operations for periods before the close of the Archstone Acquisition, except for (i) claims that principally relate to the physical condition of the assets acquired directly by the Company or Equity Residential, which generally remain the sole responsibility of the Company or Equity Residential, as applicable, and (ii) certain tax and other litigation between Archstone and various equity holders in Archstone related to periods before the close of the Archstone Acquisition, and claims which may arise due to changes in the capital structure of Archstone that occurred prior to closing, for which the seller has agreed to indemnify the Company and Equity Residential. The Company and Equity Residential jointly control the Residual JV and the Company holds a 40.0% economic interest in the Residual JV.

•

Legacy JV—As part of the Archstone Acquisition the Company entered into a limited liability company agreement with Equity Residential, through which it assumed obligations of Archstone in the form of preferred interests, some of which are governed by tax protection arrangements (the “Legacy JV”). The Company has a 40.0% interest in the Legacy JV. During the years ended December 31, 2016, 2015 and 2014, the Legacy JV redeemed certain of the preferred interests and paid accrued dividends, of which the Company's portion was $1,960,000, $14,410,000 and $6,300,000, respectively.

•

Sudbury Development, LLC—During 2015, the Company entered into a joint venture agreement to purchase land and pursue entitlements and pre-development activity for a mixed-use development project in Sudbury, MA, including multifamily apartment homes, retail, senior housing and age-restricted housing. The Company has a 60.0% ownership interest in the venture. The venture is considered a VIE, though the Company is not considered to be the primary beneficiary because the Company and its third party partner share control of the joint venture as approval from both parties is required for all significant aspects of the venture's activities including, but not limited to, changes in the ownership or capital structure of the partnership, acquisitions or dispositions by the venture and decisions about the pre-development and related activities to be performed by the venture. At December 31, 2016, the Company has an equity investment of $6,680,000 in the venture, representing the Company's share of land acquisition and pre-development costs, net of distributions of proceeds from land sales by the venture.

•

Avalon Clarendon—In May 2016, the Company entered into a joint venture agreement to facilitate the acquisition of Avalon Clarendon, located in Arlington, VA. Avalon Clarendon is part of a mixed-use development containing residential, retail, office and public parking. The Company contributed $120,300,000 to the venture for the Company's share of the purchase price. The Company had shared control of the overall venture with its partner, but had all of the rights and obligations associated with the residential component of Avalon Clarendon, containing 300 apartment homes. The joint venture partner had all of the rights and obligations associated with the retail, office and public parking components of the mixed-use development. In September 2016, the Company and its venture partner established separate legal ownership of the residential and retail, office and public parking components of the venture, and the Company retained all of the rights and obligations associated with the residential component. After this legal separation, the Company began reporting the operating results of Avalon Clarendon as part of its consolidated operations. In conjunction with the consolidation of Avalon Clarendon, the Company recorded the consolidated assets at fair value applying the framework discussed below under “Investments in Consolidated Real Estate Entities” for valuation, resulting in a gain of $4,322,000 for the difference between the fair value of Avalon Clarendon and the Company's equity interest at the date of consolidation of $115,848,000, primarily attributable to depreciation recognized during the period the community was owned in the joint venture. The Company has included this gain as a component of gain on sale of communities on the accompanying Consolidated Statements of Comprehensive Income.

North Point II JV, LP—During 2016, the Company entered into a joint venture to develop, own, and operate AVA North Point, an apartment community located in Cambridge, MA, which is currently under construction and expected to contain 265 apartment homes upon completion. The Company owns a 55.0% interest in the venture, and the venture partner owns the remaining 45.0% interest. The venture is considered to be a VIE, though the Company is not considered to be the primary beneficiary because the Company and its third party partner share control of the venture. The Company and its venture partner share decision making authority for all significant aspects of the venture's activities including, but not limited to, changes in the ownership or capital structure, the original capital budget and any changes to the budget to construct AVA North Point and the future operating budget for the community upon completion. AVA North Point is the third phase of a master planned development, the other phases of which are owned through the AC JV. During 2016, the Company provided the partners of the AC JV the opportunity to acquire the AVA North Point land parcel owned by the Company as required in the ROFO provisions for the AC JV. After certain partners of the AC JV declined to participate, the Company entered into the new joint venture and sold the land parcel to the venture in exchange for a cash payment and a capital account credit, and is overseeing the development in exchange for a developer fee. Upon sale of the land parcel, the Company recognized a gain of $10,621,000, included in gain on sale of other real estate on the accompanying Consolidated Statements of Comprehensive Income. At December 31, 2016, excluding costs incurred in excess of equity in the underlying net assets of North Point II JV, LP, the Company has an equity investment of $12,398,000.

Investments in Consolidated Real Estate Entities

During the year ended December 31, 2016, in addition to Avalon Clarendon discussed above, the Company acquired four consolidated communities:


•	Avalon Hoboken, located in Hoboken, NJ, contains 217 apartment homes and was acquired for a purchase price of $129,700,000. In conjunction with the acquisition, the Company assumed a fixed rate secured mortgage note with a principal balance of $67,904,000 and a contractual interest rate of 4.18% maturing in December 2020.


•	Avalon Potomac Yard, located in Alexandria, VA, contains 323 apartment homes and was acquired for a purchase price of $108,250,000.


•	Avalon Columbia Pike, located in Arlington, VA, contains 269 apartment homes and was acquired for a purchase price of $102,000,000. In conjunction with the acquisition, the Company assumed a fixed rate secured mortgage note with a principal balance of $70,507,000 and a contractual interest rate of 3.38% maturing in November 2019.


•	Studio 77, located in North Hollywood, CA, contains 156 apartment homes and was acquired for a purchase price of $72,100,000.

F-25

Table of Contents

These acquisitions occurred prior to the adoption of ASU 2017-01 as discussed in Note 1, “Organization, Basis of Presentation and Significant Accounting Policies,” and therefore the Company accounted for these acquisitions as business combinations and recorded the acquired assets and assumed liabilities, including identifiable intangibles, at their fair values. The Company used third party pricing or internal models for the values of the land, a valuation model for the values of the buildings and debt, and an internal model to determine the fair values of the remaining real estate assets and in-place leases. Given the heterogeneous nature of multifamily real estate, the fair values for the land, debt, 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.

Expensed transaction costs associated with the acquisitions made by the Company in 2016 and 2015, all of which were accounted for as business combinations, totaled $5,139,000 and $3,806,000, respectively. These amounts are reported as a component of expensed acquisition, development and other pursuit costs on the accompanying Consolidated Statements of Comprehensive Income. To the extent the Company received amounts related to acquired communities for periods prior to their acquisition, the Company reported these receipts, net with expensed acquisition costs. In 2014, the Company received amounts related to communities acquired in the Archstone Acquisition, for periods prior to the Company’s ownership, in excess of acquisition costs incurred, resulting in a net recovery of $7,681,000. These amounts are primarily comprised of property tax and mortgage insurance refunds.

In conjunction with the development of Avalon Sheepshead Bay, the Company entered into a joint venture agreement to construct a mixed-use building that will contain rental apartments, for-sale residential condominium units and related common elements. The Company owns a 70.0% interest in the venture and will have all of the rights and obligations associated with the rental apartments, and the venture partner owns the remaining 30.0% interest and will have all of the rights and obligations associated with the for-sale residential condominium units. The Company is responsible for the development and construction of the structure, and is providing a loan to the venture partner for the venture partner's share of costs. As of December 31, 2016, the Company has a receivable from the venture partner in the form of a variable rate mortgage note, secured by the for-sale residential condominium units in the amount of $27,241,000 for outstanding principal and interest, reported as a component of prepaid expenses and other assets on the Consolidated Balance Sheets. The Company recognizes interest income on the accrual basis. The loan will be repaid by the venture partner with the proceeds the partner receives from the sales of the residential condominium units which are expected to occur during 2017 and 2018. The venture is considered a VIE, and the Company consolidates its interest in the rental apartments and common areas.

In addition during 2016, the Company sold other real estate, including one land parcel which was sold to a joint venture in which we own a 55.0% interest, and ancillary real estate, for an aggregate sales price of $41,178,000, resulting in an aggregate gain in accordance with GAAP of $10,224,000.

During 2016, the Company completed the construction of and sold an affordable restricted apartment building, containing 77 apartment homes, which is adjacent to one of the Company's Development Communities. The Company received consideration for the sale in the form of a mortgage note, recording $18,643,000 to reflect the net present value of the note, determined based on the estimated contractual cash flows and a discount rate commensurate with the nature of the note. The note is secured by the underlying real estate, and is reported as a component of prepaid expenses and other assets on the Consolidated Balance Sheets. The Company expects to receive $16,891,000 during 2017, with the balance of the note to be received over a period of up to 35 years.

As of December 31, 2016, the Company had two ancillary land parcels that qualified as held for sale.

The operations for any real estate assets sold from January 1, 2014 through December 31, 2016 and which were classified as held for sale and discontinued operations as of and for periods prior to December 31, 2013, have been presented as income from discontinued operations in the accompanying Consolidated Statements of Comprehensive Income.

7. Commitments and Contingencies

Employment Agreements and Arrangements

The Company had employment agreements with two executive officers which expired on December 31, 2015, in accordance with their terms. At December 31, 2016, the Company does not have any employment agreements with executive officers.

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 generally 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 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, and two times for executive vice presidents. 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.

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 years ended December 31, 2016 and 2014, the Company received $417,000 and $1,933,000 in legal recoveries. There were no material receipts during the year ended December 31, 2015, excluding amounts for the Residual JV.

In conjunction with legal matters associated with the Edgewater casualty loss, the Company has established protocols for processing claims from third parties who suffered losses as a result of the fire, and many third parties have contacted the Company's insurance carrier and settled their claims.

Lease Obligations

The Company owns 16 apartment communities and two commercial properties located on land subject to land leases expiring between October 2026 and March 2142. The leases for 13 apartment communities, of which two represent dual-branded communities with one underlying land lease, and the two commercial properties, 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 five of these leases have purchase options exercisable through 2095. The Company incurred costs of $23,343,000, $21,295,000 and $21,664,000 in the years ended December 31, 2016, 2015 and 2014, respectively, related to operating leases. Three apartment communities are located on land subject to a land lease which are accounted for as capital leases, of which two represent dual-branded communities with one underlying capital land lease. In addition, the Company is party to a lease for a portion of the parking garage adjacent to a lease-up community, accounted for as a capital lease. The Company has a total lease obligation of $37,458,000 reported as a component of accrued expenses and other liabilities. Each of these land leases accounted for as capital leases have options for the Company to purchase the land at some point during the lease terms which expire in 2046 and 2086. In addition, the Company is party to 13 leases for its corporate and regional offices with varying terms through 2027, all of which are accounted for as operating leases.

The following table details the future minimum lease payments under the Company's current leases (dollars in thousands):



	Payments due by period
	2017		2018		2019		2020		2021		Thereafter

8. Segment Reporting

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

•

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 as of the beginning of the prior year. The Established Communities for the year ended December 31, 2016, are communities that are consolidated for financial reporting purposes, had stabilized occupancy as of January 1, 2015, 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 consolidated 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 consolidated communities that are under construction and have not received a certificate of occupancy for the entire community, 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, 2016.

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 property revenue less direct property operating expenses (including property taxes), and excluding corporate-level income (including management, development and other fees), corporate-level property management and other indirect operating expenses, investments and investment management expenses, expensed acquisition, development and other pursuit costs, net of recoveries, interest expense, net, loss (gain) on extinguishment of debt, net, general and administrative expense, equity in income of unconsolidated real estate entities, depreciation expense, corporate income tax expense, casualty and impairment (gain) loss, net, gain on sale of real estate assets, gain on sale of discontinued operations, income from discontinued operations and net operating income from real estate assets sold or held for sale, not classified as discontinued operations. 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.

Net operating income from real estate assets sold or held for sale, not classified as discontinued operations	$	17,509		$	34,133		$	49,708

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 at 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 total revenue and NOI the years ended December 31, 2016, 2015 and 2014 have been adjusted to exclude the real estate assets that were sold from January 1, 2014 through December 31, 2016, or otherwise qualify as held for sale and/or discontinued operations as of December 31, 2016, as described in Note 6, “Real Estate Disposition Activities.” Segment information for gross real estate as of December 31, 2015 and 2014 has not been adjusted to exclude real estate assets that were sold or otherwise qualified as held for sale subsequent to December 31, 2015.

9. Stock-Based Compensation Plans

The Company's 2009 Stock Option and Incentive Plan (the “2009 Plan”) includes an authorization to issue shares of the Company's common stock, par value $0.01 per share. At December 31, 2016, the Company has 878,622 shares remaining available to issue under the 2009 Plan, exclusive of shares that may be issued to satisfy currently outstanding awards such as stock options or performance awards. In addition, any awards that were outstanding under the Company's1994 Stock Option and Incentive Plan (the “1994 Plan”) on May 21, 2009, the date the Company adopted the 2009 Plan, that are subsequently forfeited, canceled, surrendered or terminated (other than by exercise) will become available for awards under the 2009 Plan. The 2009 Plan provides for various types of equity awards to associates, officers, non-employee directors and other key personnel of the Company and its subsidiaries. The types of awards that may be granted under the 2009 Plan include restricted stock, stock options that qualify as incentive stock options (“ISOs”) under Section 422 of the Code, non-qualified stock options, stock appreciation rights and performance awards, among others. The 2009 Plan will expire on May 21, 2019.

Options outstanding and exercisable under the 2009 and 1994 Plans at December 31, 2016 had an intrinsic value of $9,380,000 and $2,237,000, respectively. Options exercisable under the 2009 and 1994 Plans had a weighted average contractual life of 5.4 years and 1.4 years, respectively. The intrinsic value of options exercised during 2016, 2015 and 2014 was $9,187,000, $18,080,000 and $20,028,000, respectively.

The cost related to stock-based employee compensation for employee stock options included in the determination of net income is based on estimated forfeitures for the given year. Estimated forfeitures are adjusted to reflect actual forfeitures at the end of the vesting period. There were no stock options granted in 2016, 2015 and 2014.

The Company has a compensation framework under which share-based compensation is granted, composed of annual restricted stock awards for which one third of the award vests annually over a three year period, and multi-year long term incentive performance awards. Under the Company's multi-year long term incentive compensation framework, the Company grants a target number of performance awards, with the ultimate award determined by the total shareholder return of the Company's common stock and/or operating performance metrics, measured in each case over a measurement period of up to three years. The performance awards are earned in the form of restricted stock, or upon election of the recipient, up to 25% in the form of stock options, for which one third of the award vests annually over an additional three year period following the completion of the performance cycle.

In general, performance awards are forfeited if the employee's employment terminates for any reason prior to the measurement date. However, for performance awards with performance periods beginning on or after January 1, 2015, after the first year of the performance period, if the employee's employment terminates on account of death, disability, retirement, or termination without cause at a time when the employee meets the age and service requirements for retirement, the employee shall vest in a pro rata portion of the award (based on the employee's service time during the performance period), with such vested portion to be earned and converted into shares at the end of the performance period based on actual achievement under the performance award.

Information with respect to performance awards granted is as follows:

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, 2016 was 0.8%. The application of estimated forfeitures did not materially impact compensation expense for the years ended December 31, 2016, 2015 and 2014. As discussed Note 1, “Organization, Basis of Presentation and Significant Accounting Policies,” under “Recently Issued and Adopted Accounting Standards,” the Company will adopt the provision of ASU 2016-09 and recognize forfeitures as they occur beginning in 2017.

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 692,812 shares remaining available for issuance under the ESPP. 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 Company modified the ESPP beginning in 2014, establishing two purchase periods. The first purchase period begins January 1 and ends June 10, and the second purchase period begins July 1 and ends December 10. 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 11,348, 10,667 and 9,848 shares and recognized compensation expense of $289,000, $321,000 and $407,000 under the ESPP for the years ended December 31, 2016, 2015 and 2014, 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. Related Party Arrangements

Unconsolidated Entities

The Company manages unconsolidated real estate entities for which it receives asset management, property management, development and redevelopment fee revenue. From these entities, the Company earned fees of $5,599,000, $9,947,000 and $11,050,000 in the years ended December 31, 2016, 2015 and 2014, respectively. These fees are recognized on an accrual basis when earned in accordance with the accounting guidance applicable to revenue recognition, and are included in management, development and other fees on the accompanying Consolidated Statements of Comprehensive Income. In addition, the Company has outstanding receivables associated with its property and construction management role of $5,239,000 and $3,832,000 as of December 31, 2016 and 2015, respectively.

Director Compensation

Directors of the Company who are also employees receive no additional compensation for their services as a director. Following each annual meeting of stockholders, non-employee directors receive (i) a number of shares of restricted stock (or deferred stock awards) having a value of $130,000 and (ii) a cash payment of $70,000, payable in quarterly installments of $17,500. 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, beginning in May 2014, the Lead Independent Directors receive in the aggregate an additional annual fee of $25,000 payable in equal quarterly installments of $6,250, and non-employee directors serving as the chairperson of the Audit, Compensation and Nominating Committees receive additional cash compensation of $10,000 per year payable in quarterly installments of $2,500.

The Company recorded non-employee director compensation expense relating to restricted stock grants and deferred stock awards in the amount of $1,216,000, $1,135,000 and $1,049,000 for the years ended December 31, 2016, 2015 and 2014, respectively, as a component of general and administrative expense. Deferred compensation relating to these restricted stock grants and deferred stock awards to non-employee directors was $531,000, $488,000 and $452,000 on December 31, 2016, 2015 and 2014, respectively. During the year ended December 31, 2016, the Company issued 44,327 shares in conjunction with the conversion of deferred stock awards.

11. Fair Value

Financial Instruments Carried at Fair Value

Derivative Financial Instruments

Currently, the Company uses interest rate swap and interest rate cap agreements to manage its interest rate risk. These instruments are carried 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 reducing credit risk concentration. The Company believes the likelihood of realizing losses from counterparty nonperformance 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, such as interest rate, term to maturity and volatility, 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, 2016, 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 2016 or 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 derivative positions at December 31, 2016 (dollars in thousands):



	Non-designated Hedges Interest Rate Caps			Cash Flow Hedges Interest Rate Caps			Cash Flow Hedges Interest Rate Swaps
Notional balance	$	715,820		$	35,898		$	800,000
Weighted average interest rate (1)	2.5		%	2.7		%	N/A
Weighted average swapped/capped interest rate	6.2		%	5.9		%	2.3		%
Earliest maturity date	February 2017			April 2019			November 2017
Latest maturity date	November 2021			April 2019			November 2017

_________________________________


(1)	For interest rate caps, represents the weighted average interest rate on the hedged debt.

In 2016 and 2015, the Company entered into $1,200,000,000 of forward interest rate swap agreements executed to reduce the impact of variability in interest rates on a portion of the Company's expected debt issuance activity in 2016 and 2017. In May 2016, the Company settled $400,000,000 of the aggregate outstanding swaps, as discussed below. For the remaining outstanding swaps, at maturity of the agreements, the Company expects to cash settle the contracts and either pay or receive cash for the then current fair value. Assuming that the Company issues the debt as expected, the impact from settling these positions will then be recognized over the life of the issued debt as a yield adjustment.

In May 2016, in conjunction with the Company's May 2016 unsecured note issuance, the Company settled $400,000,000 of forward interest rate swap agreements designated as cash flow hedges of the interest rate variability on the forecasted issuance of the unsecured notes, making a payment of $14,847,000. The Company has deferred the effective portion of the fair value change of these swaps in accumulated other comprehensive loss on the accompanying Consolidated Balance Sheets, and will recognize the impact as a component of interest expense, net, over the life of the unsecured notes.

Excluding derivatives executed to hedge secured debt on communities classified as held for sale, the Company had 11 derivatives designated as a cash flow hedge and 15 derivatives not designated as hedges at December 31, 2016. Fair value changes for derivatives not in qualifying hedge relationships for the years ended December 31, 2016 and 2015, were not material. During 2016, the Company deferred $5,556,000 of losses for cash flow hedges reported as a component of other comprehensive income (loss).

The following table summarizes the deferred losses reclassified from accumulated other comprehensive income as a component of interest expense, net (dollars in thousands):



	For the year ended
	12/31/16		12/31/15		12/31/14
Cash flow hedge losses reclassified to earnings	$	6,433	$	5,774	$	6,237

The Company anticipates reclassifying approximately $6,975,000 of hedging losses from accumulated other comprehensive loss into earnings within the next 12 months to offset the variability of cash flows of the hedged item during this period. The Company did not have any derivatives designated as fair value hedges as of December 31, 2016 and 2015.

Redeemable Noncontrolling Interests

The Company provided redemption options (the “Puts”) that allow joint venture partners of the Company to require the Company to purchase their interests in the investment at a guaranteed minimum amount related to three ventures. The Puts are payable in cash. The Company determines the fair value of the Puts based on unobservable inputs considering the assumptions that market participants would make in pricing the obligations, applying a guaranteed rate of return to the joint venture partners' net capital contribution balances as of period end. Given the significance of the unobservable inputs, the valuations are classified in Level 3 of the fair value hierarchy.

The Company issued units of limited partnership interest 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 agreements, 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 DownREITs 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, within principal protected accounts. 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 and are Level 1 within the fair value hierarchy.

Other Financial Instruments

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

The Company values its unsecured notes using quoted market prices, a Level 1 price within the fair value hierarchy. The Company values its notes payable and outstanding amounts under the Credit Facility and Term Loan 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 notes payable and amounts outstanding under its Credit Facility and Term Loan are Level 2 prices as the majority of the inputs used to value its positions fall within Level 2 of the fair value hierarchy.

13. Subsequent Events

The Company has evaluated subsequent events through the date on which this Form 10-K was filed, the date on which these financial statements were issued, and identified the items below for discussion.

In January 2017, the Company entered into an agreement to sell an operating community containing 450 apartment homes and net real estate of $51,342,000 as of December 31, 2016, resulting in the community qualifying as held for sale. The Company expects to complete the sale in the first quarter of 2017.

In January 2017, the Company sold two undeveloped land parcels located in Newcastle, WA that are adjacent to one of the Company's Development Communities for $20,500,000.

In February 2017, a fire occurred at the Company's Avalon Maplewood Development Community, located in Maplewood, NJ, which was under construction and not yet occupied. The Company is currently assessing its direct losses resulting from the fire, which could vary based on costs and time to rebuild the portion of the Development Community that was destroyed and/or damaged, as well as its potential liability to third parties who may have incurred damages on account of the fire. While the Company currently believes that its direct losses and any potential liability to third parties will be substantially covered by its insurance policies, including coverage for the replacement cost of the building, third party claims and business interruption loss, subject to deductibles as well as a self-insured portion of the property insurance for which the Company is obligated for 12% of the first $50,000,000 in losses, the Company can give no assurances in this regard and continues to evaluate this matter.

In February 2017, the Company repaid $17,300,000 of variable rate debt secured by Avalon at Mountain View at its scheduled maturity date.
