The Board of Directors currently consists of eleven members. As previously announced, Lance R. Primis, a current director, has decided not to stand for re‑election. The Board of Directors has nominated for election the other ten current directors, and has reduced the size of the Board to ten to eliminate the resulting vacancy, effective immediately following the Annual Meeting. Accordingly, ten nominees will stand for election at the Annual Meeting and if elected will serve until the 2018 Annual Meeting of Stockholders and until their successors are elected and qualify. The following individuals have been nominated by the Board of Directors to serve as directors: Glyn F.

Aeppel, Terry S. Brown, Alan B. Buckelew, Ronald L. Havner, Jr., Richard J. Lieb, Timothy J. Naughton, Peter S. Rummell, H. Jay Sarles, Susan Swanezy and W. Edward Walter (each, a “Nominee” and, collectively, the “Nominees”). The Board of Directors anticipates that each of the Nominees, if elected, will serve as a director. However, if any person nominated by the Board of Directors is unable to serve or for good cause will not serve, the proxies will be voted for the election of such other person as the Board of Directors may recommend. You may not vote for more than ten directors at the Annual Meeting.

Only holders of record of Common Stock as of the close of business on the Record Date are entitled to vote on this proposal. Proxies will be voted for all of the Nominees unless contrary instructions are set forth on the enclosed proxy card. Under the Company’s bylaws, a majority of the total votes

cast as to each Nominee is required to elect such Nominee. Under Maryland law, abstentions and broker non‑votes are not treated as votes cast. Accordingly, an abstention or broker non‑vote will have no effect on the result of the vote.

The following biographical descriptions set forth information with respect to the Nominees, based on information furnished to the Company by each Nominee, and include the specific experience, qualifications, attributes and skills that led to the Board’s conclusion that each should serve as a

director in light of the Company’s business and structure. There is no family relationship between any Nominee, director or executive officer of the Company.

Mr. Naughton, 55, is the Company’s Chairman of the Board, Chief Executive Officer and President and has been a director of the Company since September 2005. He has served as Chairman of the Board since May 2013, as Chief Executive Officer since January 2012, and as President since February 2005. Mr. Naughton’s prior roles included serving as the Company’s Chief Operating Officer, Chief Investment Officer, and Regional Vice President—Development and Acquisitions. Mr. Naughton has been with the

Company and its predecessors since 1989.

Forum. Mr. Naughton received his Masters of Business Administration from Harvard Business School in 1987 and earned his undergraduate degree in Economics with High Distinction from the University of Virginia, where he was elected to Phi Beta Kappa. The Board has concluded that Mr. Naughton should serve as a director based on

his history with and knowledge of the Company, his performance and achievements as Chairman of the Board, President and Chief Executive Officer of the Company, and his strong background in the real estate business, including years of experience in both property investment and development.

Ms. Aeppel, 58, has been a director of the Company since May 2013, and has more than 30 years of experience in property acquisitions, development and financing.

Ms. Aeppel is a director of Simon Property Group, Inc., a publicly traded retail real estate company. She also serves on the board of Exclusive Resorts, a private luxury resort and vacation rental home company. The Board has concluded that Ms. Aeppel should serve as a director based on her broad background and long experience in property acquisitions, branding, development and financing.

Mr. Brown, 55, has been a director of the Company since January 1, 2015, and is the Chairman and Chief Executive Officer of Asana Partners, a private real estate investment company, which he helped found in 2015. Prior to that he was Chairman and Chief Executive Officer of EDENS, one of the country’s leading private owners, operators and developers of real estate. Mr. Brown joined EDENS as its CEO in 2002. Before joining Edens he was Chief Executive Officer of Andersen Corporate Finance LLC

(NASD broker‑dealer subsidiary of Arthur Andersen LLP) where he was responsible for strategy and investment banking activities on a global basis across the real estate, manufacturing, technology, services and energy industries. The Board has concluded that Mr. Brown should serve as a director based on his significant experience in a sector of the real estate industry that is complementary to the Company’s multifamily platform.

Mr. Buckelew, 68, has been a director of the Company since September 2011. He was appointed Chief Information Officer of Carnival Corporation, a publicly traded cruise line holding company, in December 2016.  From 2013 to 2016 he served as Carnival’s Chief Operating Officer. Prior to that he was President of Princess Cruises, Inc. from 2004 to 2013, overseeing the brand and operations of Princess Cruises. Mr. Buckelew also served as Chief Operating Officer for Cunard Line from 2004 to 2007. Prior to

these roles, Mr. Buckelew served from 2000 to 2004 as Executive Vice President of Corporate Services for Princess Cruises, with responsibility for the Company’s strategic planning, marketing and yield management functions. The Board has concluded that Mr. Buckelew should serve as a director based on his significant experience as an executive in an industry that, like multifamily apartment communities, is capital intensive and consumer‑driven.

Mr. Havner, 59, has been a director of the Company since September 2014. Mr. Havner is the Chairman of the Board and Chief Executive Officer of Public Storage, a publicly traded real estate investment trust that primarily acquires, develops, owns and operates self‑storage facilities, where he also served as President from 2002 through 2016. He was elected Vice Chairman and Chief Executive Officer of Public Storage in 2002 and was elected Chairman of the Board in August 2011. Mr. Havner has been Chairman of the Board of PS Business Parks, Inc., a publicly traded real estate company, since March 1998, and has served as a director of California Resources Corp., a publicly traded oil and natural gas exploration and production company, since 2014. Mr. Havner was the 2014 Chairman of the Board of Governors of NAREIT.

In considering the nomination of Mr. Havner for re‑election to the Board, the Nominating and Corporate Governance Committee and the full Board considered whether Mr. Havner’s role at Public Storage and PS Business Parks, together with his service on the Board of California Resources Corp., would allow him to dedicate sufficient time and focus on his duties as a director of AvalonBay. The Board considered Mr. Havner’s performance as a valued and reliable member of the Board and its Committees over the past year, including his 100% attendance at Board and Committee meetings during 2016. In accordance with the Board’s standard practice, Mr. Havner reviews three years’ of regularly scheduled

AvalonBay Board and Committee meeting dates so that he has time to arrange his schedule to provide for availability at AvalonBay meetings.

In determining that Mr. Havner’s other commitments would not prevent him from dedicating sufficient time and attention to the Company, the Board and the Nominating and Governance Committee considered the substantial overlap between his duties at Public Storage and at PS Business Parks. Public Storage owns a significant percentage of PS Business Parks, PS Business Parks’ financial records are reflected in Public Storage’s financial statements under the equity method of accounting, and there are a number of contractual relationships between the two entities, including a cost sharing and administration services agreement.

The Board and the Nominating and Governance Committee also believe that Mr. Havner provides great value to the Board and is an important contributor to discussions and decision‑making. Mr. Havner is a highly respected and experienced member of the real estate industry with current executive experience with a leading developer and operator. Accordingly, the Board has concluded that Mr. Havner should serve as a director based upon his business and investment expertise acquired in successfully leading an equity REIT for over a decade and his demonstrated reliability and commitment to service on the Board.

Mr. Lieb, 57, has been a director of the Company since September 2016. Mr. Lieb has been a Managing Director and Chairman of Real Estate at Greenhill & Co., LLC, a publicly traded investment bank, since November 2016. Mr. Lieb previously served Greenhill in a variety of senior positions, most recently as head of Greenhill’s Real Estate, Gaming and Lodging Group. Mr. Lieb was also Greenhill’s Chief Financial Officer from 2008 to 2015. Prior to joining Greenhill in 2005, Mr. Lieb

spent more than 20 years with Goldman, Sachs & Co., where he headed its Real Estate Investment Banking Department from 2000 to 2005. Mr. Lieb is also a director of CBL & Associates Properties, Inc., and VEREIT, Inc., both publicly traded REITs. The Board has concluded that Mr. Lieb should serve as a director based on his experience working with real estate clients on a wide range of capital markets, capital allocation, strategic planning and corporate transaction matters.

M. Rummell, 71, has been a director of the company since September 2007. He is currently a private investor and most recently served as the Chief Executive Officer of the Jack Nicklaus Companies in Palm Beach, Florida, from August 2008 through May 2009. The Jack Nicklaus Companies runs Mr. Nicklaus’s worldwide golf

course design and related licensing business. Prior to that, from January 1997 until his retirement in July 2008, Mr. Rummell was Chairman and CEO of The St. Joe Company, one of Florida’s largest real estate operating companies and the state’s largest private landowner. From 1985 until 1996, Mr. Rummell served as President of Disney

From 1983 until 1985, he was Vice Chairman of the Rockefeller Center Management Corporation in New York City. Mr. Rummell is a past chairman of

the ULI. The Board has concluded that Mr. Rummell should serve as a director based on his experience in leadership positions of companies with significant real estate holdings and operations and his broad knowledge of the real estate industry.

Mr. Sarles, 71, has been a director of the Company since September 2005, and has served as the Lead Independent Director of the Company since May 2015 (see “Board of Directors and its Committees—Leadership Structure and Lead Independent Director”). He retired from full time business leadership positions in 2005, having most recently served as vice chairman of Bank of America Corporation. Prior to that he served as Vice Chairman and Chief Administrative Officer of Fleet Boston Financial (“Fleet”) with responsibility for administrative functions, risk management, technology and operations, treasury services, corporate strategy and mergers and acquisitions. During his 37 years at Fleet, Mr. Sarles oversaw

virtually all of Fleet’s businesses at one time or another, including the company’s wholesale banking business from 2001 to 2003. These included commercial finance, real estate finance, capital markets, global services, industry banking, middle market and large corporate lending, small business services and investment banking businesses. Mr. Sarles is a director of Ameriprise Financial, Inc., a publicly traded financial planning services company. The Board has concluded that Mr. Sarles should serve as a director based on his extensive experience as an executive officer with a variety of responsibilities at a large financial institution with varied operations.

Ms. Swanezy, 58, has been a director of the Company since September 2016.  Since 2010 she has been a partner at Hodes Weill & Associates L.P., a global advisory boutique firm focused on the real estate management industry.  Previously Ms. Swanezy served as Managing Director, Global Head of Capital Raising for Real Estate Products at Credit Suisse Group AG, and held a variety of positions at Deutsche Bank AG and its affiliates, including serving as a Partner and Managing

Director – Client Relations for RREEF, the real estate investment management business of Deutsche Bank’s Asset Management division.  The Board has concluded that Ms. Swanezy should serve as a director because of her broad and varied experience in evaluating real estate companies, investment opportunities and real estate asset allocation strategies.

Mr. Walter, 61, has been a director of the Company since September 2008. He has been the Robert and Lauren Steers Chair in Real Estate at the Steers Center for Global Real Estate at Georgetown University’s McDonough School of Business since November 2014.  He served as President and Chief Executive Officer of Host Hotels & Resorts, Inc. (“Host”), a publicly traded premier lodging real estate company, from October 2007 through December 2016. From 2003 until October 2007, he served as Executive Vice President and Chief Financial Officer of Host. From 1996 until 2003, he served in various senior management positions with Host, including Chief Operating Officer. Mr. Walter was a member of the Board of Directors of Host from October 2007 through December 2016. Mr. Walter is also past

Chairman of the Board of Directors of the National Kidney Foundation, a Director of the Real Estate Round Table, the Chairman of the Federal City Council, and a member of the Board of Visitors of the Georgetown University Law Center. The Board has concluded that Mr. Walter should serve as a director based on his demonstrated business, financial and organizational experience as both the past chief financial officer and chief executive officer of a publicly traded corporation with significant real estate investment holdings and operations.

The Board recommends that the stockholders ratify the Audit Committee’s selection of Ernst & Young LLP (“Ernst & Young”) as the independent auditors of the Company for fiscal year 2017. Ernst & Young was also the Company’s principal independent auditors for fiscal year 2016. If the selection of Ernst & Young is not ratified, the Audit Committee anticipates that it will nevertheless engage Ernst & Young as auditors for fiscal year 2017 but will consider whether it should select a different auditor for fiscal year 2018. If the

selection of Ernst & Young is ratified by the stockholders, the Audit Committee may nevertheless determine, based on changes in fees, personnel or for other reasons, to engage a firm other than Ernst & Young for the 2017 audit.

Representatives of Ernst & Young are expected to be present at the Annual Meeting and will have the opportunity to make a statement, if they desire to do so, and to respond to appropriate questions.

Only holders of record of Common Stock as of the close of business on the Record Date are entitled to vote on this proposal. Proxies will be voted for ratification of the selection of Ernst & Young as the Company’s independent auditors for fiscal year 2017 unless contrary instructions are set forth on the enclosed proxy card. A majority of the total

votes cast on the proposal at the Annual Meeting is required to ratify the selection of Ernst & Young. Under Maryland law, abstentions and broker non‑votes are not treated as votes cast. Accordingly, an abstention or broker non‑vote will have no effect on the result of the vote.

The Board of Directors believes that stock‑based incentive awards can play an important role in the success of the Company. Stock-based incentive awards play an integral role in our pay-for-performance philosophy.  Additionally, stock-based compensation helps the Company remain competitive in retaining and attracting highly qualified employees upon whom the future growth and success of the Company depend. The Company grants annual stock bonus and annual performance awards from its equity incentive plan.  The purpose of the equity incentive plan is to promote the success and enhance the value of the Company by linking the personal interests of employees, officers and directors of the Company to those of the Company’s stockholders.

On February 16, 2017, the Board, upon the recommendation of the Compensation Committee, approved an amendment and restatement of the Company’s 2009 Stock Option and Incentive Plan.  

As so amended and restated, the name of the plan would be the AvalonBay Communities, Inc. Second Amended and Restated 2009 Equity Incentive Plan (the “Amended 2009 Plan”).  The Board’s approval of the Amended 2009 Plan is subject to the approval of the Company’s stockholders, which is being sought by this proposal.  The effective date of the Amended 2009 Plan will be the date of stockholder approval; for ease of exposition, in the discussion below it is assumed that the Amended 2009 Plan is approved on, and therefore the effective date of the plan will be, May 18, 2017.

The Amended 2009 Plan provides flexibility to the Compensation Committee to use various equity‑based incentive awards as compensation tools to motivate the Company’s workforce. A copy of the Amended 2009 Plan is attached as Exhibit A to this proxy statement and is incorporated herein by reference.

The following description of certain features of the Amended 2009 Plan is intended to be a summary only. The summary is qualified in its entirety by the full text of the Amended 2009 Plan that is attached hereto as Exhibit A.

Plan Administration.  The Amended 2009 Plan is administered by the Compensation Committee. The Compensation Committee has full power to select, from among the individuals eligible for awards, the individuals to whom awards will be granted, to make any combination of awards to participants, and to determine the specific terms and conditions of each award, subject to the provisions of the Amended 2009 Plan. The Compensation Committee may delegate to our Chief Executive Officer (or other executive officers) the authority to grant awards to employees who are not subject to the reporting and other provisions of Section 16 of the Securities Exchange Act of 1934 (the “Exchange Act”) and not a Covered Employee under Section 162(m) of the Code, subject to certain limitations and guidelines.

Eligibility.  Persons eligible to participate in the Amended 2009 Plan will be those full or part-time officers, employees, non-employee directors and other key persons (including consultants and prospective employees) of the Company and its subsidiaries as selected from time to time by the

Compensation Committee in its discretion. As of the date of this proxy statement, the Company has approximately 3,000 employees, 70 of whom are officers, and ten non-employee directors (nine immediately following the 2017 Annual Meeting).  With respect to Company associates, the Company's recent practice has been to generally make equity incentive awards to associates who have attained the officer, director or senior director level; approximately 195 associates are eligible to receive awards pursuant to this practice.

Stock Options.  The Amended 2009 Plan permits the granting of (1) options to purchase Common Stock intended to qualify as incentive stock options under Section 422 of the Code and (2) options that do not so qualify. No more than 8,000,000 shares will be issued in the form of incentive stock options. Options granted under the Amended 2009 Plan will be non-qualified options if they fail to qualify as incentive options or exceed the annual limit on incentive stock options. Incentive stock options may only be granted to employees of the Company and its subsidiaries. Non-qualified options may be granted to any persons eligible to receive incentive options and to non-employee directors and key persons. The option exercise price of each option will be determined by the Compensation Committee but may not be less than 100% of the fair market value

of the Common Stock on the date of grant. Fair market value for this purpose will be the last reported sale price of the shares of Common Stock on the NYSE on the date of grant. The exercise price of an option may not be reduced after the date of the option grant, other than to appropriately reflect changes in our capital structure.

The term of each option will be fixed by the Compensation Committee and may not exceed ten years from the date of grant. The Compensation Committee will determine at what time or times each option may be exercised. Options may be made exercisable in installments and the exercisability of options may be accelerated by the Compensation Committee. In general, unless otherwise permitted by the Compensation Committee, no option granted under the Amended 2009 Plan is transferable by the optionee other than by will or by the laws of descent and distribution, and options may be exercised during the optionee’s lifetime only by the optionee, or by the optionee’s legal representative or guardian in the case of the optionee’s incapacity.

Upon exercise of options, the option exercise price must be paid in full either in cash, by certified or bank check or other instrument acceptable to the Compensation Committee or by delivery (or attestation to the ownership) of shares of Common Stock of the Company that are beneficially owned by the optionee. Subject to applicable law, the exercise price may also be delivered to the Company by a broker pursuant to irrevocable instructions to the broker from the optionee. In addition, the Compensation Committee may permit non-qualified options to be exercised using a net exercise feature which reduces the number of shares issued to the optionee by the number of shares with a fair market value equal to the exercise price.

To qualify as incentive options, options must meet additional federal tax requirements, including a $100,000 limit on the value of shares subject to incentive options that first become exercisable by a participant in any one calendar year.

Stock Appreciation Rights.  The Compensation Committee may award stock appreciation rights subject to such conditions and restrictions as the Compensation Committee may determine. Stock appreciation rights entitle the recipient to shares of Common Stock equal to the value of the appreciation in the stock price of a designated number of shares of our Common Stock over the

exercise price. The exercise price is the fair market value of the Common Stock on the date of grant.

Restricted Stock.  The Compensation Committee may award shares of Common Stock to participants subject to such conditions and restrictions as the Compensation Committee may determine. These conditions and restrictions may include the achievement of certain performance goals (as summarized above) and/or continued employment with us through a specified restricted period. However, in the event these awards granted to employees have a performance‑based goal, the restriction period will be at least one year, and in the event these awards granted to employees have a time-based restriction (without any prior performance condition to the grant or vesting thereof), the restriction period will be at least one year, but vesting can occur incrementally over the one-year period.  Awards made to employees after May 18, 2017 for up to 5% of the awards reserved and available for issuance as of that date may be awarded, in total, without regard to such minimum restriction or vesting period.

Restricted Stock Units.  The Compensation Committee may award restricted stock units to any participants. Restricted stock units are ultimately payable in the form of shares of Common Stock and may be subject to such conditions and restrictions as the Compensation Committee may determine. These conditions and restrictions may include the achievement of certain performance goals (as summarized above) and/or continued employment with the Company through a specified vesting period. However, in the event these awards granted to employees have a performance‑based goal, the restriction period will be at least one year, and in the event these awards granted to employees have a time-based restriction (without any prior performance condition to the grant or vesting thereof), the restriction period will be at least one year, but vesting can occur incrementally over the one-year period. Awards made to employees after May 18, 2017 for up to 5% of the awards reserved and available for issuance as of that date may be awarded, in total, without regard to such minimum restriction or vesting period. In the Compensation Committee’s sole discretion, it may permit a participant to make an advance election to receive a portion of his or her future cash compensation otherwise due in the form of a restricted stock unit award, subject to the participant’s compliance with the procedures established by the Compensation Committee and requirements of Section 409A of the Code. During

the deferral period, the deferred stock awards may be credited with dividend equivalent rights.

Unrestricted Stock Awards.  The Compensation Committee may also grant shares of Common Stock which are free from any restrictions under the Amended 2009 Plan. Unrestricted stock may be granted to any participant in recognition of past services or other valid consideration and may be issued in lieu of cash compensation due to such participant.  However, any such grant of restricted stock that is made to employees must comply with the limitation that no more than 5% of the awards reserved and available for issuance as of May 17, 2017 may, in total, be issued without regard to the minimum one-year restriction or vesting period.

Performance Share Awards.  The Compensation Committee may grant performance share awards to any participant which entitle the recipient to receive shares of Common Stock upon the achievement of certain performance goals (as summarized above) and such other conditions as the Compensation Committee shall determine. The period during which performance is to be measured for such awards shall not be less than one year, provided however that Awards made to employees after May 18, 2017 for up to 5% of the awards reserved and available for issuance as of that date may be awarded, in total, without regard to a minimum restriction or vesting period.

Dividend Equivalent Rights.  The Compensation Committee may grant dividend equivalent rights to participants which entitle the recipient to receive credits for dividends that would be paid if the recipient had held specified shares of Common Stock. Dividend equivalent rights may be granted as a component of another award (other than a stock option or stock appreciation right) or as a freestanding award. Dividend equivalent rights may be settled in cash, shares of Common Stock or a combination thereof, in a single installment or installments, as specified in the award.

Cash-Based Awards.  The Compensation Committee may grant cash bonuses under the Amended 2009 Plan to participants. The cash bonuses may be subject to the achievement of certain performance goals (as summarized above).

Sale Event.  The Amended 2009 Plan provides that upon the effectiveness of a “sale event” as such term is defined in the Amended 2009 Plan, and except as otherwise provided by the Compensation Committee in an award agreement,

all awards will be terminated unless the parties agree to assume or continue the awards with appropriate adjustments. In the event that awards are assumed, continued or substituted in connection with a Sale Event, then the award will become fully vested and nonforfeitable in the event that the grantee's employment or other business relationship with the Company is terminated (i) by the Company without cause or (ii) by the grantee for Good Reason, in either case in connection with or within 24 months following the Sale Event, except as may otherwise be provided in the relevant award agreement. In case awards are not assumed, the Company may make or provide for a cash payment to participants holding options and stock appreciation rights equal to the difference between the per share cash consideration and the exercise price of the options or stock appreciation rights.

Adjustments for Stock Dividends, Stock Splits, Etc.  The Amended 2009 Plan requires the Compensation Committee to make appropriate adjustments to the number of shares of Common Stock that are subject to the Amended 2009 Plan, and to any outstanding awards and/or to the price for each share of Common Stock subject to outstanding awards of stock options and stock appreciation rights to reflect stock dividends, stock splits, extraordinary cash dividends and similar events.

Tax Withholding.  Participants in the Amended 2009 Plan are responsible for the payment of any federal, state or local taxes that the Company is required by law to withhold upon the exercise of options or stock appreciation rights or vesting of other awards. Subject to approval by the Compensation Committee, participants may elect to have tax withholding obligations satisfied by authorizing the Company to withhold shares of Common Stock to be issued pursuant to the exercise or vesting.

Clawback Policy.  Awards made under the Amended 2009 Plan are subject to the Company's clawback policy as in effect from time to time.

Amendments and Termination.  The Board may at any time amend or discontinue the Amended 2009 Plan and the Compensation Committee may at any time amend or cancel any outstanding award for the purpose of satisfying changes in the law or for any other lawful purpose. However, no such action may adversely affect any rights under any outstanding award without the holder’s consent. To the extent required under the rules of the

NYSE, any amendments that materially change the terms of the Amended 2009 Plan will be subject to approval by our stockholders. Amendments shall also be subject to approval by our stockholders if and to the extent determined by the Compensation Committee to be required by the Code to preserve the qualified status of incentive options or to ensure that compensation earned under the Amended 2009 Plan qualifies as performance‑based compensation under Section 162(m) of the Code.

Effective Date of Amended 2009 Plan.  The Board adopted the Amended 2009 Plan on February 16, 2017, and the Amended 2009 Plan becomes effective on the date it is approved by stockholders. No awards may be granted under the Amended 2009 Plan after May 15, 2027.  If the Amended 2009 Plan is not approved by stockholders, the plan as currently in effect will continue until it expires, and awards may be granted thereunder, in accordance with its terms.

The following is a summary of the principal federal income tax consequences of certain transactions under the Amended 2009 Plan. It does not describe all federal tax consequences under the Amended 2009 Plan, nor does it describe state or local tax consequences.

Incentive Options.  No taxable income is generally realized by the optionee upon the grant or exercise of an incentive option. If shares of Common Stock issued to an optionee pursuant to the exercise of an incentive option are sold or transferred after two years from the date of grant and after one year from the date of exercise, then (i) upon sale of such shares, any amount realized in excess of the option price (the amount paid for the shares) will be taxed to the optionee as a long-term capital gain, and any loss sustained will be a long-term capital loss, and (ii) the Company will not be entitled to any deduction for federal income tax purposes. The exercise of an incentive option will give rise to an item of tax preference that may result in alternative minimum tax liability for the optionee.

If shares of Common Stock acquired upon the exercise of an incentive option are disposed of prior to the expiration of the two-year and one-year holding periods described above (a “disqualifying disposition”), generally (i) the optionee will realize ordinary income in the year of disposition in an amount equal to the excess (if any) of the fair market value of the shares of Common Stock at exercise (or, if less, the amount realized on a sale of such shares of Common Stock) over the option price thereof, and (ii) we will be entitled to deduct such amount. Special rules will apply where all or a portion of the exercise price of the incentive option is paid by tendering shares of Common Stock.

If an incentive option is exercised at a time when it no longer qualifies for the tax treatment described above, the option is treated as a non-qualified option. Generally, an incentive option will not be eligible for the tax treatment described above if it is exercised more than three months following termination of employment (or one year in the case of termination of employment by reason of disability). In the case of termination of employment by reason of death, the three‑month rule does not apply.

Non-Qualified Options.  No income is realized by the optionee at the time the option is granted. Generally (i) at exercise, ordinary income is

realized by the optionee in an amount equal to the difference between the option price and the fair market value of the shares of Common Stock on the date of exercise, and we receive a tax deduction for the same amount, and (ii) at disposition, appreciation or depreciation after the date of exercise is treated as either short-term or long-term capital gain or loss depending on how long the shares of Common Stock have been held. Special rules will apply where all or a portion of the exercise price of the non-qualified option is paid by tendering shares of Common Stock. Upon exercise, the optionee will also be subject to Social Security taxes on the excess of the fair market value over the exercise price of the option.

Other Awards.  The Company generally will be entitled to a tax deduction in connection with an award under the Amended 2009 Plan in an amount equal to the ordinary income realized by the participant at the time the participant recognizes such income. Participants typically are subject to income tax and recognize such tax at the time that an award is exercised, vests or becomes non-forfeitable, unless the award provides for a further deferral.

Parachute Payments.  The vesting of any portion of an option or other award that is accelerated due to the occurrence of a change of control may cause a portion of the payments with respect to such accelerated awards to be treated as “parachute payments” as defined in the Tax Code. Any such parachute payments may be non-deductible to the Company, in whole or in part, and may subject the recipient to a non-deductible 20 percent federal excise tax on all or a portion of such payment (in addition to other taxes ordinarily payable).

Limitation on Deductions.  Under Section 162(m) of the Tax Code, the Company’s deduction for certain awards under the Amended 2009 Plan may be limited to the extent that the Chief Executive Officer or other executive officer whose compensation is required to be reported in the summary compensation table (other than the Principal Financial Officer) receives compensation in excess of $1 million a year (other than performance‑based compensation that otherwise meets the requirements of Section 162(m) of the Tax Code). The Amended 2009 Plan is structured to allow certain awards to qualify as performance‑based compensation.

Only holders of record of Common Stock as of the close of business on the Record Date are entitled to vote on this proposal. Proxies will be voted for approval of adoption of the AvalonBay Communities, Inc. Second Amended and Restated 2009 Equity Incentive Plan unless contrary instructions are set forth on the enclosed proxy card. Under Maryland law, this proposal requires the affirmative vote of a majority of all of the votes cast on the matter. Under NYSE rules, for

purposes of the vote to approve our Second Amended and Restated 2009 Equity Incentive Plan, an abstention constitutes a vote cast but a broker non-vote does not. Accordingly, a broker non-vote will not be counted in determining the outcome of the vote on this matter, while an abstention will have the same effect as a vote against this matter.

The Compensation Discussion and Analysis beginning on page 31 of this proxy statement describes the Company’s executive officer compensation program and decisions made by the Compensation Committee and the Board of Directors with respect to the 2016 compensation of our Chief Executive Officer and other officers named in the Summary Compensation Table on page 54 (the “Named Executive Officers”). As noted in the Compensation Discussion and Analysis, the Company’s goals for its executive compensation program are (i) to attract, motivate and retain experienced and effective executives, (ii) to direct the performance of those executives with clearly defined goals and measures of achievement and (iii) to align the interests of management with the interests of our stockholders.

While the vote on the following resolution is advisory in nature and therefore will not bind us to take any particular action, our Board of Directors will carefully consider the stockholder vote resulting from the proposal in making future decisions regarding our compensation program. The Board of Directors is asking stockholders to cast a non‑binding, advisory vote on the following resolution:

“RESOLVED, that the compensation paid to the Company’s Named Executive Officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, compensation tables and any related material disclosed in this proxy statement, is hereby APPROVED, on a non‑binding, advisory basis, by the stockholders of the Company.”

Only holders of record of Common Stock as of the close of business on the Record Date are entitled to vote on this proposal. Proxies will be voted for adoption of the resolution approving the compensation disclosed unless contrary instructions are set forth on the enclosed proxy card. A majority of the votes cast on the proposal at the Annual Meeting is required to provide

non‑binding advisory approval of the compensation paid to the Company’s Named Executive Officers. Under Maryland law, abstentions and broker non‑votes are not treated as votes cast. Accordingly, an abstention or broker non‑vote will have no effect on the result of the vote.

The stockholders of the Company are entitled to cast a non-binding advisory vote at least every six years on how frequently the Company will submit a non-binding, advisory proposal to approve the compensation of the Company’s Named Executive Officers similar to Proposal 4.  The prior vote on this matter was held in 2011 and the Board recommended that the non-binding advisory vote on executive compensation be held every year (rather than every two years or every three years) and the stockholders elected to have such vote annually.  Accordingly the Board is again asking

the stockholders to vote on whether the stockholders of the Company shall have an advisory vote on the compensation of the Company’s Named Executive Officers as set forth in the Company’s proxy statement every year, every two years or every three years. The Company believes that it is appropriate to continue to hold such a vote every year so that the Board receives feedback from the Company’s stockholders on executive compensation decisions in a timely manner.

Only holders of record of Common Stock as of the close of business on the Record Date are entitled to vote on this proposal. Because there are three alternatives, it is possible that none of the three alternatives will receive a majority of votes cast. In that case, the results of the advisory vote regarding frequency of a shareholder advisory vote on executive compensation shall be determined by whichever of the choices — every year, every two years, or every three years —

 receives the greatest number of votes cast.  Under Maryland law, abstentions and broker non-votes are treated as not voting. Accordingly, an abstention or broker non-vote will have no effect on the outcome of the vote.  If no voting specification is made on a properly returned or voted proxy card, the proxies named on the proxy card will vote for a frequency of EVERY YEAR for future advisory votes regarding executive compensation.

The Company has adopted a Code of Business Conduct and Ethics (the “Code”). The Code constitutes a “code of ethics,” as defined by the SEC, that applies to the Company’s Board of Directors as well as its Chief Executive Officer, Chief Financial Officer, principal accounting officer, controller, and other employees of the Company. In addition, the Company has adopted Corporate Governance Guidelines. Copies of the Code and the Corporate Governance Guidelines are available on the Investor Relations section of the Company’s website (www.avalonbay.com) under “Corporate Governance Documents.” To the

extent required by the rules of the SEC and the NYSE, we will disclose amendments and waivers relating to these documents in the same place on our website. Additional information on corporate governance policies is included in “Compensation Policies” on page 51, including information on the following Company policies: Executive Stock Ownership Guidelines; Prohibition Against Hedging, Pledging or Borrowing against Company Stock; Severance Policy; and Policy on Recoupment of Incentive Compensation (Clawback Policy).

The Board of Directors currently consists of eleven directors, ten of whom are candidates for election. As previously announced, Lance R. Primis, a current director, has decided not to stand for re‑election. The Board of Directors met five times during 2016. The Board of Directors schedules regular executive sessions at each of its meetings during which the Company’s independent directors meet without management participation. During 2016, each of the directors attended at least 75% of the total number of meetings of the Board of Directors and meetings of the committees of the Board of Directors of which he or she was a member. The Board’s policy is that each director attend the Company’s annual meetings of stockholders at which he or she is a nominee, and all directors who were nominees were in attendance at the 2016 Annual Meeting of Stockholders.

As discussed below under Nominating and Corporate Governance Committee, the Board considers a variety of factors when choosing candidates for Board appointment or nomination. While the Board values long‑tenured directors who know the Company and management well, the Board also believes that it is important to assure that from time to time vacancies occur on the Board that create opportunities for new directors

who may bring different or more recent experiences or expertise to the Board. Consistent with this philosophy, five new directors have joined the AvalonBay Board on or subsequent to the 2013 Annual Meeting of Stockholders: Glyn Aeppel, Ron Havner, Terry Brown, Richard Lieb and Susan Swanezy (with the last two joining in 2016).

In 2016, the Company’s Board of Directors amended the Company’s Corporate Governance Guidelines to incorporate new term expectations that reflect the Board’s view of the importance of board succession planning. Specifically, the Corporate Governance Guidelines, as amended, (i) express an expectation that a director will not be re‑nominated after the completion of 12 full years of service or within the several years that follow; (ii) express an expectation that the Lead Independent Director will serve in that role for approximately three to five years, and (iii) express an expectation that Committee chairs will serve for three to five years. In each case, the guideline is flexible and the exact timing for any transition will depend on the needs of the Board at the time and the timing of identification and nomination of a successor. The Board would not expect to apply this guideline to an employee director (at the present time, the only employee on the Company’s Board is the Chief Executive Officer).

The Board of Directors has established an Audit Committee. The current members of this committee are Mr. Buckelew (Chair), Ms. Aeppel and Messrs. Brown and Havner.  Following the Annual Meeting the Board expects that Mr. Lieb and Ms. Swanezy will be appointed to the Audit Committee and that Ms. Aeppel will rotate off the Audit Committee. The Board of Directors has determined that Mr. Buckelew is an “audit committee financial expert” as defined by the SEC, based on his MBA, experience as Chief Financial Officer at Princess Cruises, and the fact that the Internal Audit function of Carnival Corporation has reported to him. The designation of Mr. Buckelew by the Board as an “audit committee financial expert” is not intended to be a representation that he is an expert for any purpose as a result of this designation, nor is it intended to impose on him any duties, obligations or liabilities that are greater than the duties, obligations or liabilities imposed on him as a member of the Audit Committee and

the Board in the absence of this designation. The Board of Directors has determined that the members of the Audit Committee, including the audit committee financial expert, are “independent” under the rules of the NYSE. The Audit Committee, among other functions, has the sole authority to appoint and replace the independent auditors, is responsible for the compensation and oversight of the work of the independent auditors, reviews the results of the audit engagement with the independent auditors, and reviews and discusses with management and the independent auditors quarterly and annual financial statements and major changes in accounting and auditing principles. The Audit Committee met seven times during 2016. The Board of Directors has adopted a written charter for the Audit Committee. A copy of the Audit Committee charter is available on the “Investor relations” section of the Company’s website (www.avalonbay.com) under “Corporate Governance Documents.”

The Board of Directors has established a Compensation Committee. The current members of this committee are Messrs. Walter (Chair), Primis and Sarles. Following the Annual Meeting, Mr. Primis will no longer serve as a director and the Board expects that Mr. Buckelew will be appointed to the Compensation Committee.  The Board of Directors has determined that the members of the Compensation Committee are “independent” under the rules of the NYSE. The Compensation Committee, among other functions, reviews, designs and determines management compensation structures, programs and amounts, establishes corporate and management performance goals and objectives, and reviews and makes recommendations to the Board of Directors regarding the Company’s incentive compensation plans, including the Company’s 1994 Stock Incentive Plan, the Company’s Amended and Restated 2009 Equity Incentive Plan, as currently in effect and as the same may be amended pursuant to a proposal at this Annual Meeting (collectively, the “Equity Incentive Plans”). The Compensation Committee also reviews

employment agreements and arrangements with senior officers. In addition, our Equity Incentive Plans provide that the Committee, in its discretion, may delegate to the Chief Executive Officer of the Company all or part of the Committee’s authority and duties under the Equity Incentive Plans with respect to awards, including the granting of awards to individuals who are not subject to the reporting and other provisions of Section 16 of the Exchange Act. The Compensation Committee has engaged Steven Hall & Partners, an executive compensation consulting firm, to provide it with independent advice and counsel on executive and board compensation, as well as competitive pay practices. Steven Hall & Partners does not provide any services directly to the Company or its management. The Compensation Committee met four times during 2016. The Board of Directors has adopted a written charter for the Compensation Committee. A copy of the Compensation Committee charter is available on the “Investor relations” section of the Company’s website (www.avalonbay.com) under “Corporate Governance Documents.”

The Board of Directors has established a Nominating and Corporate Governance Committee. The current members of this committee are Messrs. Sarles (Chair), Primis, Rummell, and Walter. Following the Annual Meeting, Mr. Primis will no longer serve as a director and the Board expects that Ms. Aeppel will be appointed to the Nominating and Corporate Governance Committee. The Board of Directors has determined that the members of the Nominating and Corporate Governance Committee are “independent” under the rules of the NYSE. The Nominating and Corporate Governance Committee’s functions include: identifying individuals qualified to become Board members; considering policies relating to Board and committee meetings; recommending the establishment or dissolution of Board committees; reviewing and considering succession plans with respect to the positions of Chairman of the Board and Chief Executive Officer (including through periodic evaluation and discussion with the Board of internal candidates for such succession); reviewing policies and activities in the areas of political contributions, charitable giving and corporate responsibility; and addressing other issues regarding corporate governance. The Nominating and Corporate Governance Committee met four times during 2016. The Board of Directors has adopted a written charter for the Nominating and Corporate Governance Committee. A copy of the Nominating and Corporate Governance Committee charter is available on the “Investor relations” section of the Company’s website (www.avalonbay.com) under “Corporate Governance Documents.”

In evaluating and determining whether to recommend a person as a candidate for election as a director, the Nominating and Corporate Governance Committee considers the qualifications set forth in the Company’s corporate governance guidelines, which include the nominee’s business and professional background; history of leadership or contributions to other organizations; functional skill set and expertise; general understanding of marketing, finance, accounting and other elements relevant to the success of a publicly‑traded company in today’s business environment; and service on other boards of directors. In addition, the Board may consider diversity of background, experience and thought in evaluating and recommending candidates for election. The Board believes that diversity is important because a variety of points of view can contribute to a more effective decision‑making process. The Nominating and Corporate Governance Committee may employ a

variety of methods for identifying and evaluating nominees for director. The Nominating and Corporate Governance Committee may assess the size of the Board, the need for particular expertise on the Board, the upcoming election cycle of the Board and whether any vacancies are expected, due to retirement or otherwise. In the event that vacancies are anticipated or otherwise arise, the Nominating and Corporate Governance Committee will consider various potential candidates for director which may come to the Nominating and Corporate Governance Committee’s attention through current Board members, professional search firms, stockholders or other persons. These candidates are evaluated at regular or special meetings of the Nominating and Corporate Governance Committee, and may be considered at any time during the year.

In exercising its function of recommending individuals for nomination by the Board for election as directors, the Nominating and Corporate Governance Committee will consider nominees recommended by stockholders. The procedure by which stockholders may submit such recommendations is set forth in the Company’s Bylaws. See “Other Matters – Stockholder Nominations for Directors and Proposals for Annual Meetings” for a summary of these requirements. When nominations are properly submitted, the Nominating and Corporate Governance Committee will consider candidates recommended by stockholders under the criteria summarized above. Following verification of the stockholder status of persons proposing candidates, the Nominating and Corporate Governance Committee makes an initial analysis of the qualifications of any candidate recommended by stockholders or others pursuant to the criteria summarized above to determine whether the candidate is qualified for service on the Board of Directors before deciding to undertake a complete evaluation of the candidate. If any materials are provided by a stockholder or professional search firm in connection with the nomination of a director candidate, such materials are forwarded to the Nominating and Corporate Governance Committee as part of its review. The same identifying and evaluating procedures apply to all candidates for director nomination, including candidates submitted by stockholders. In the case of stockholder nominations, the Board may also consider the specific information required to be provided by the nominating stockholder pursuant to the requirements of the Company’s Bylaws.  Stockholders may also nominate directors in accordance with the proxy access provisions of the Company’s Bylaws, as described in “Other

Matters - Stockholder Nominations for Directors and Proposals for the Annual Meeting”.

If you would like the Nominating and Corporate Governance Committee to consider a prospective candidate, please submit the candidate’s name and qualifications and other information in

accordance with the requirements for director nominations by stockholders in the Company’s Bylaws to: AvalonBay Communities, Inc., Ballston Tower, 671 N. Glebe Road, Suite 800, Arlington, VA 22203, Attention: Corporate Secretary.

The Board of Directors has established an Investment and Finance Committee. The current members of this committee are Ms. Aeppel (Chair), and Messrs. Brown, Buckelew, Havner, Naughton, and Rummell. Following the Annual Meeting, the Board expects that Mr. Lieb and Ms. Swanezy will be appointed to the Investment and Finance Committee and Mr. Buckelew will rotate off the Investment and Finance Committee.  The Investment and Finance Committee was formed, among other things, to review and monitor the

acquisition, disposition, development and redevelopment of the Company’s communities, and review and monitor the financial structure, capital sourcing strategy and financial plans and projections of the Company. The Investment and Finance Committee has authority, subject to certain limits and guidelines set by the Board of Directors and Maryland law, to approve investment and financing activity. The Investment and Finance Committee met three times during 2016.

Timothy J. Naughton, our Chief Executive Officer and President, also serves as the Company’s Chairman of the Board. The Board believes that the Company is best served by having Mr. Naughton serve as Chairman of the Board in addition to Chief Executive Officer and President, as opposed to appointing one of the other current directors or a future director to serve as Chairman of the Board. Among other benefits, Mr. Naughton’s role as Chief Executive Officer and President enables him, working with the Lead Independent Director, to act as a bridge between management and the Board, helping management and the Board to act with a common purpose. Mr. Naughton’s combined roles as Chief Executive Officer, President and Chairman of the Board promote unified leadership and direction for the

Company. To help assure sound corporate governance practices, the Board of Directors established the position of Lead Independent Director in 2003 and Mr. Sarles currently serves in that role. Mr. Sarles’ role as Lead Independent Director includes presiding at all meetings of the Board of Directors at which the Chairman of the Board is not present, serving as a liaison between the Chairman of the Board and the independent directors, establishing and approving meeting agendas for the Board, having the authority to call meetings of the independent directors, conferring with the Chairman of the Board and the Chief Executive Officer regularly, and acting as a contact person for stockholders and others who wish to communicate with the independent directors.

The Company and the Board have a number of practices with regard to Board oversight of risk management matters. The charter of each of the Company’s Board committees provides that each committee shall, from time to time to the extent that committee deems appropriate, review risk and compliance matters relevant to that committee and report the results of such review to the full Board. As required by NYSE rules, the charter of the Audit Committee states that the Audit Committee will assist with Board oversight of risk and compliance matters, and in any event will review the perceived major financial risk exposures of the Company and the steps management has taken to monitor and control such exposures. At most regularly scheduled Board meetings, the Board

reviews key matters relating to the Company’s finances, liquidity, operations and investment activity. On an annual basis, the Board engages in a broader discussion about company‑wide risk management.

Although it is not the primary reason for the selection of the current leadership structure by the Board, the Company and the Board believe that the current leadership structure of the Board, including both a Chairman of the Board and a separate Lead Independent Director, helps facilitate these risk oversight functions by providing multiple channels for risk related concerns and comments. The Company’s operations involve various risks that could have adverse

consequences, including those described in the Company’s Annual Report on Form 10‑K and other filings with the SEC. The Board recognizes that it is neither possible nor prudent to eliminate all risk. Despite the risk oversight activities described above, there can be no assurance that

the Company’s current practices have identified every potential material risk, are sufficient to address these risks, or that any risks will not result in a material adverse effect on the Company’s business or operations.

The NYSE has adopted independence standards for companies listed on the NYSE, which apply to the Company. These standards require a majority of the Board of Directors to be independent and every member of the Audit Committee, Compensation Committee and Nominating and Governance Committee to be independent. NYSE standards provide that a director is considered independent only if the Board of Directors “affirmatively determines that the director has no material relationship with the listed company (either directly or as a partner, shareholder or officer of an organization that has a relationship with the company).” In addition, NYSE rules and related NYSE commentary generally provide that:

To determine which of its members is independent, the Board of Directors used the above standards and also considered whether a director had any other past or present relationships with the Company which created conflicts or the appearance of conflicts.

Based on consideration of the foregoing and the absence of any other such transactions, relationships or arrangements found as a result of this review, the Board determined that all nominees for directors are independent, except for Mr. Naughton, who currently serves as the Company’s Chairman of the Board, Chief Executive Officer and President.

NYSE rules provide for additional independence standards that apply to members of the Audit Committee and the Compensation Committee. The Board has determined that each current and proposed member of these committees satisfies these additional standards.

We consider our relationship with our stockholders to be an important part of the Company’s success and we value the outlook and opinions of our investors. During 2016 our management reached out to stockholders who collectively held over 60% of the Company’s outstanding stock for the purpose of discussing the Company’s practices and policies with respect to environmental, social and governance matters (“ESG”) and management spoke with stockholders holding 43.5% of outstanding stock regarding such issues, in addition to speaking with Institutional Shareholder Services and Glass Lewis.  These discussions addressed governance matters including board composition and refreshment, executive compensation and sustainability efforts. The feedback from stockholders was conveyed to

and discussed with the Nominating and Governance Committee and full Board.

The goal of these conversations was to ensure that management and the Board understood and considered the ESG issues that matter most to our stockholders and to enable the Company to address them effectively.

In addition to conversations with our stockholders, the Company receives correspondence throughout the year from stockholders and stockholder advocacy groups and responds and/or shares this correspondence with the Nominating and Corporate Governance Committee and the full Board where requested or otherwise appropriate.

Any stockholder or other interested party may contact any of our directors, including the Lead Independent Director or our independent directors as a group, by writing to them at the following address. The envelope in which you send your

letter should clearly specify the name of the individual director or group of directors to whom your letter is addressed. Any communications received in this manner will be forwarded as addressed.

The Audit Committee of the Board of Directors of AvalonBay Communities, Inc., a Maryland corporation (the “Company”), reviews the financial reporting process of the Company on behalf of the Board of Directors. Management has primary responsibility for this process, including the Company’s system of internal controls, and for the preparation of the Company’s consolidated financial statements in accordance with generally accepted accounting principles and on the Company’s internal controls over financial reporting. The Company’s independent auditors, and not the Audit Committee, are responsible for auditing and expressing an opinion on the conformity of the Company’s audited financial statements to generally accepted accounting principles. In this context, during 2016 and 2017, the Audit Committee reviewed and discussed the audited financial statements and E&Y’s evaluation of the Company’s internal control over financial reporting with management and the independent auditors. The Audit Committee has discussed with the independent auditors the matters required to be discussed by the Auditing Standards adopted

by the Public Company Accounting Oversight Board (“PCAOB”). In addition, the Audit Committee received from the independent auditors the written disclosures required by the PCAOB regarding the independent auditor’s communications with the Audit Committee regarding independence, and the Audit Committee discussed with the independent auditors their independence from the Company and its management. Relying on the reviews, disclosures and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10‑K for the year ended December 31, 2016, for filing with the SEC, and the Board of Directors has approved this recommendation.

The Audit Committee pre‑approves all audit and permissible non‑audit services provided by the independent auditors. These services may include audit services, audit‑related services, tax services and other services. Pre‑approval is provided for up to one year, and any pre‑approval is detailed as to the particular service or category of services and is subject to a specific budget.

The independent auditors and management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent auditors in accordance with this pre‑approval, and the fees for the services performed to date. The Audit Committee may also pre‑approve particular services on a case‑by‑case basis.

The Company’s Code of Business Conduct and Ethics, adopted by the Company’s Board of Directors and evidenced in writing, provides that no employee of the Company, including an executive officer or director, may engage in activities that create a conflict of interest with the Company unless all relevant details have been disclosed and an appropriate waiver permitting the conduct has been received. An activity constitutes a conflict of interest under the Code if (i) the activity could adversely affect or compete with the Company, (ii) any interest, connection or benefit to the employee or director from the activity could reasonably be expected to cause such employee or director to consider anything other than the best interest of the Company when deliberating and

voting on Company matters or (iii) any interest, connection or benefit to the employee or director from the activity could give such employee or director or a member of his or her family an improper benefit that he or she obtains on account of his or her position within the Company. An executive officer or member of the Board of Directors may only receive a waiver from the Board or any designated committee of the Board, and any waiver granted to an executive officer or director will be disclosed to the Company’s stockholders to the extent required by law or NYSE rules. The Nominating and Governance Committee of the Board (or any other committee that is designated) is responsible for administering the Code for executive officers and directors.

Summary:  2016 was a strong year for AvalonBay, in which our operating and development capabilities, together with favorable apartment fundamentals, helped us deliver a sixth consecutive year of healthy operating results. Some highlights for the year include:

Operating Activity:  Rental revenue for Established Communities for 2016 increased 4.3% over the prior year period. NOI for Established Communities increased 4.8% for the same period.

Development Activity:  We completed eight new development communities, representing a total capital investment of approximately $510 million. These new communities were delivered at an average cost basis of under $300,000 per apartment home. We also started nine new apartment communities that are projected to contain approximately 2,700 apartment homes. At year‑end 2016, we had approximately $85 million in land held for development and our development rights pipeline consisted of 25 communities, representing $3.0 billion in projected total capital cost.

Redevelopment Activity:  During 2016, the Company completed the redevelopment of 10 communities containing an aggregate of 2,739 apartment homes, for a total capital cost of approximately $116 million, excluding costs incurred prior to redevelopment.

Dividend Growth:  In February 2017 we announced a dividend increase of 5.2%. Since the first quarter of 2011 we have increased our quarterly dividend nearly 60%.

Capital Markets Activity:  We raised approximately $1.35 billion by borrowing approximately $1.1 billion in unsecured debt and sourcing the balance through asset sales and from distributions from unconsolidated real estate entities.

Portfolio Management:  During 2016 the Company purchased five stabilized communities for $532 million.  During 2016, the Company sold seven wholly-owned operating communities, containing 2,051 apartment homes, for an aggregate sales price of $523 million.

Earnings and Core FFO Growth:  Earnings per share for the year was $7.52. “Core FFO” per share increased by 8.5% over the prior year to $8.19. For the three years ended December 31, 2016 (the period measured for this metric in our maturing performance awards), our Core FFO grew at a 9.55% annualized rate.

Other Achievements:  The Company was ranked #1 for its positive online reputation among the top 10 REITs in the United States based on J. Turner

Research’s most recent Online Reputation Assessment™ Power Rankings.

In the area of corporate responsibility, AvalonBay was once again awarded a Green Star by the annual Global Real Estate Sustainability Benchmark (GRESB) survey. The GRESB survey evaluates hundreds of real estate companies in such areas as management, policy, development, governance, sustainability, and environmental and social programs/policies. In every category, AvalonBay continued to score well above the average of its peers in residential real estate, ranking second in the United States. Its rating was also above the global industry average in almost every category, ranking third worldwide. In attaining the coveted Green Star for environmental achievement, AvalonBay ranked in the top quartile in terms of implementation and measurement, management and policy, and development. AvalonBay’s overall 2016 GRESB score marks the fourth consecutive year of improvement in the rankings, beginning with its first year of participation in 2013.

Definitions and Reconciliations:  For definitions and reconciliations of FFO, Core FFO, Established Communities, and NOI, see pages 32‑34, 36, and 38-39, respectively, of the Company’s Annual Report on Form 10‑K for the year ended December 31, 2016 (the “Form 10-K”), as filed with the SEC, and pages 37-40, 43, and 45-46 of the printed copy of the Form 10-K accompanying this Proxy Statement.

Base Salary.  Mr. Naughton, our Chairman and CEO, continued to have a base salary of $950,000 in 2016, which remained unchanged since 2013 when he was appointed as Chairman of the Board.

Cash Bonus.  Mr. Naughton’s target cash bonus for 2016 was $1,425,000 or 150% of base salary. Seventy‑five percent of the target cash bonus is based on corporate performance factors and 25% is based on individual performance. The achievement levels for the corporate performance and individual factors were judged to be 100.7% and 110%, respectively, resulting in a final cash bonus for 2016 of $1,468,106.

Stock Bonus.  Mr. Naughton’s target stock bonus for 2016 was $600,000.  The performance measures used in calculating the stock bonus reflect different elements of the Company’s performance and are not duplicative of the performance measures used to evaluate corporate performance under the annual cash bonus program. The achievement level for these stock

bonus performance measures for 2016 was 94.16%, which resulted in a payout of $564,950.  The payout is delivered in the form of restricted stock that vests ratably over three years from the date of grant. Please note that this award will be disclosed in the 2018 proxy statement Summary Compensation Table as it was granted in 2017.

Performance Awards.  Mr. Naughton received a target performance award totaling $3,362,500 for the 2014 – 2016 performance period. 66.7% of the target award was tied to three-year total shareholder (“TSR”) return metrics, including absolute and relative comparisons, and 33.4% of the target award was tied to three-year relative financial operating metrics. The Company achieved 162.3% of target payout for the 2014 – 2016 performance awards. Based on the closing stock price of the Company’s common stock on the NYSE on February 16, 2017 of $179.07, the earned performance awards (paid out in restricted shares subject to three‑year time vesting) are valued at $7,577,705.

As previously announced at the 2016 Annual Meeting of Stockholders, the Company’s executive officer compensation for 2015 was approved by over 90% of the votes cast on the matter. The Compensation Committee and the Company considered these results to be an endorsement by stockholders of the Company’s compensation structure, target level and actual executive compensation.

In addition to the annual, non-binding, advisory vote on executive compensation, this year the Company is holding an advisory vote on the frequency of such “Say-on-Pay” votes, as required by SEC rules, and is recommending that such vote continue to occur every year.

In determining the total compensation for each Named Executive Officer, which is the sum of base salary, bonus and long‑term incentives, the Compensation Committee generally considers a number of factors on a subjective basis, including:

An officer’s target compensation is not mechanically set to be a particular percentage of the peer group average, although, as noted, the Compensation Committee does review the officer’s compensation relative to the peer group to help the Compensation Committee perform the subjective analysis described above.

An officer’s target compensation may vary from the peer group data for the following reasons:

Our incentive programs are designed so that actual performance in excess of the performance targets results in payouts above target and actual performance below the performance targets results in payouts below target or no payout, but there are caps on above‑target payouts.

Companies for Performance Award Measurement Purposes

The Company uses a different peer group for determining performance under its performance awards. The peer group for determining the level of total target compensation is based in part on size parameters since the Company is competing with similar sized companies for executive talent. For the performance awards, size is less of a consideration and more emphasis is placed on multi‑family peers since operating performance and shareholder return are more appropriately compared with direct competitors in our specific industry.

For the 2014 – 2016 performance awards relating to three‑year relative total shareholder return, the following indices were used:

For the 2014 – 2016 performance awards relating to operating metrics, the following multifamily REITs were used as peer companies:

These companies were chosen primarily because they are in the multifamily industry.

Please note that Associated Estates was acquired in August 2015, Home Properties was acquired in October 2015, and Post Properties was acquired in December 2016.  For companies that were acquired during the performance period, their

operating metrics were factored in for the portion of the performance period for which they were publicly traded companies that published operating results.

Individual Goals and Achievement for Annual Cash Component

Individual goals for the officers include the executive’s leadership and managerial performance, as well as specific objectives, and are evaluated on a subjective basis annually. Individual performance for Mr. Naughton was determined by the Compensation Committee.

Pursuant to our Deferred Compensation Plan, certain employees, including the named executive officers, may defer up to 25% of base annual salary and up to 50% of annual cash bonus on a pre‑tax basis and receive a tax‑deferred return on those deferrals. Deferral elections are made by eligible employees during an open enrollment period each year for amounts to be earned in the following year. Participating employees direct the deemed investment of their deferral accounts by selecting among certain available investments in mutual funds.

We have an employee stock purchase plan that allows our employees the opportunity to purchase up to $25,000 of our Common Stock per year at a 15% discount to the lower of the closing price of the Common Stock, as reported on the NYSE, on

the first business day of the purchase period or the closing price of the Common Stock on the last day of the purchase period. For 2016 there were two purchase periods, January 1 – June 10 and July 1 – December 10, with the opportunity to purchase up to $12,500 of our Common Stock at the discounted rate previously mentioned during each of the two purchase periods (up to $25,000 annually). In addition, we maintain a 401(k) retirement savings plan and annually match 50% of the first six percent of base salary and cash bonus contributed to such plan by any employee (subject to certain tax limitations). We offer medical, dental and vision plans, a portion of the cost of which is paid by the employee. We also provide life insurance, accidental dismemberment insurance, and short‑term and long‑term disability insurance for each employee.

Executive Stock Ownership Guidelines.  The Company believes that stock ownership by its executive officers is important and has established formal Executive Stock Ownership Guidelines for officers who are at the executive vice president level or above or are subject to reporting under Section 16 of the Exchange Act. These guidelines provide that persons holding the title of Chairman of the Board, Chief Executive Officer or President are expected to maintain ownership of Common Stock (including unvested restricted shares) equal to six times their base salary. The multiples that apply to other covered officers are as follows: Chief Financial Officer and Executive Vice Presidents—three times; Senior Vice Presidents—one and one‑half times; Vice Presidents—one time. The full text of the Executive Stock Ownership Guidelines, which includes the time periods by which such ownership must be achieved and a retention policy during periods of non‑achievement, is posted on the Investor Relations section of the Company’s website (www.avalonbay.com) under “Corporate Governance Documents.” The Company also has Director Stock Ownership Guidelines as discussed in “Director Compensation and Director Stock Ownership Guidelines” of the proxy statement.

Prohibition Against Hedging, Pledging or Borrowing Against Company Stock.  The Company has adopted a formal policy prohibiting its executive officers and directors from (i) borrowing money from a broker or other lender that is secured by Company securities, and (ii) holding Company securities in a brokerage account that has outstanding “margin” debt. In addition, the policy prohibits sales of Company securities by an executive officer or director if he or she does not own the security at the time of the sale (a “Short Sale”), and prohibits the buying or selling of puts or calls in respect of any Company securities.

Severance Policy.  The Board has adopted a Policy Regarding Shareholder Approval of Future Severance Agreements (the “Severance Policy”). The Severance Policy generally provides that the Company will not, without stockholder approval or ratification, enter into or bind the Company to the terms of any future severance agreement with a senior executive officer that provides for severance benefits (as defined) in excess of 2.99 times the sum of the officer’s base salary plus annual cash bonus. The Severance Policy, which is posted on the Investor Relations section of the Company’s website (www.avalonbay.com) under

“Corporate Governance Documents,” provides additional detail regarding the application of this policy.

Policy on Recoupment of Incentive Compensation (Clawback Policy).  The Board has adopted a Policy for Recoupment of Incentive Compensation (i.e., a compensation clawback policy), which applies to senior officers (generally senior vice presidents and above). Pursuant to this policy, in the event the Company is required to prepare an accounting restatement due to the material non‑compliance of the Company with any financial reporting requirement, then an independent committee of the Board of Directors may require any covered officer to repay to the

Company all or part of any “Excess Compensation” that such officer had previously received. Excess Compensation is defined as that part of the incentive compensation received by a covered officer during the 3‑year period preceding the publication of the restated financial statement that was in excess of the amount that such officer would have received had such incentive compensation been calculated based on the financial results reported in the restated financial statement. The full text of the policy is posted on the Investor Relations section of the Company’s website (www.avalonbay.com) under “Corporate Governance Documents.”

The Compensation Committee determines the number of shares underlying options and shares of restricted stock to award to officers as part of annual compensation. Those members of the Board of Directors who would qualify for service on the Compensation Committee review and ratify these awards at the Board’s regularly scheduled February meeting. The award date for options and stock grants is generally the date of ratification, but may be delayed to a date after such ratification if there is a pending announcement by the Company of material non‑public information, such as an earnings release. In all cases, our options are granted: (i) on the dates described above;

(ii) on the date of a new hire’s start with the Company as approved by the CEO in advance of the start date; or (iii) on the date of approval by the CEO for retention or recognition purposes up to a Board‑authorized maximum value of $250,000. Option exercise prices are determined by the NYSE closing price of our Common Stock on the date of grant. Additionally, all officers must receive prior authorization for any purchase or sale of our Common Stock (unless made pursuant to a previously approved Rule 10b5‑1 plan), which, in the case of open market transactions, is generally only given during approved trading windows that are generally established in advance based upon earnings release dates.

The Compensation Committee reviewed and considered risks arising from the Company’s compensation policies and practices for its employees. This review included consideration of the following specific elements of the Company’s executive compensation policies and procedures:

Following this review, the Compensation Committee concluded that any risks arising from the Company’s compensation policies and practices are not reasonably likely to have a material adverse effect on the Company at this time, although no assurances can be given in this regard.

The SEC requires that this report comment upon the Company’s policy with respect to Section 162(m) of the Tax Code, which limits the deductibility on the Company’s tax return of compensation over $1 million to the Chief Executive Officer and any of its three other most highly paid executive officers (other than the Chief Financial Officer) unless, in general, the compensation is paid pursuant to a plan which is performance‑related, non‑discretionary and has been approved by the Company’s stockholders. The Company believes that, because it qualifies as a REIT under the Tax Code and pays dividends sufficient to minimize federal income taxes, the payment of compensation that does not satisfy the requirements of Section 162(m) will generally not

affect the Company’s net income. If that compensation does not qualify for a deduction under Section 162(m), there could be a modest effect on the Company’s dividend requirements to qualify as a REIT or on the tax characterization of such dividends. The Company does not believe that Section 162(m) will materially affect its dividend requirements or the taxability of stockholder distributions, although no assurance can be given in this regard due to the variety of factors that affect the tax position of each stockholder. For these reasons, the Compensation Committee’s compensation policy and practices are not directly guided by considerations relating to Section 162(m).
