2017 Notice of Annual Meeting
2017 Proxy Statement and
2016 Annual Report on Form 10-K
00.02.966.1 (3/17)	aetna.com

April 7, 2017

To Our Shareholders:

Aetna delivered solid financial results while firmly advancing our mission of building a healthier world — one person, one family and one community at a time.

In a rapidly evolving market, we grew total revenue by nearly five percent to $63 billion and generated net income of nearly $2.3 billion. We ended 2016 serving 23.1 million medical members in communities across the country.

Our performance was driven by multiple businesses, particularly our Government business, where Medicare membership grew nearly 13 percent and premiums grew year-over-year by 15 percent. For the third consecutive year, we increased the percentage of our Medicare Advantage members enrolled in plans rated 4-stars or higher, reaching 92 percent in 2016 — the highest percentage among our publicly-traded peers. These strong star ratings are a reflection of our commitment to improving quality of care and service, which keeps our members out of the hospital and in their homes and communities. Additionally, our Consumer Health and Services team is enhancing our care model to proactively engage members using real-time data paired with predictive analytics to improve health. We expect these improvements will provide members, including those facing chronic illness, with a simpler way to navigate through the health care system.

We also successfully advanced our strategy to help transform the health care system from volume-based payment models to care-based models that reward the quality and value provided to our members. At the end of 2016, over 45 percent of Aetna’s medical spend was running through a value-based care model, positioning us to achieve our goal of 75 percent by 2020. We also announced new joint-venture agreements with Banner Health in Arizona and Texas Health Resources, demonstrating our commitment to strong, collaborative relationships with leading providers across the country.

Improving the health of communities across the nation is an important component of our mission. In 2016, the Aetna Foundation, in partnership with the American Public Health Association and the National Association of Counties, launched the Healthiest Cities and Counties Challenge. Over the next several years, the Foundation will work to identify and share best practices and proven innovations in communities across the country to improve the social determinants of health – including healthy behaviors, community safety and environmental exposures.

Mark T. Bertolini
Chairman and Chief Executive Officer

Following a thorough business review and in light of increasing losses, we decided to reduce our presence on the individual public exchanges established by the Affordable Care Act. For the full-year 2016, we reported $450 million in pre-tax losses in our individual ACA-compliant products. As the health care policy debate moves beyond the ACA, Aetna will be a positive voice for reforms that improve the quality and affordability of heath care for all Americans. Going forward, we will continue to advocate for policies that provide consumers with greater choice and flexibility to meet their health care needs while facilitating a sustainable marketplace for insurers, including Aetna, to serve the uninsured and underserved markets.

Although we could not get to a successful conclusion with our Humana acquisition, our strategy does not change. We will deploy our capital efficiently to deliver on our commitment to build a consumer-centered health care system that improves affordability, promotes quality, and provides a simpler user experience. Our vision is for every consumer to enjoy the healthiest life journey possible, and we are committed to helping them realize that goal.

Thank you for your continued support and investment in Aetna.

Mark T. Bertolini
Chairman and CEO

GOVERNANCE OF THE COMPANY

At Aetna Inc. (“Aetna”), we believe sound corporate governance principles are good for our business, our industry, the competitive marketplace and all of those who place their trust in us. We have embraced the principles behind the Sarbanes-Oxley Act of 2002, as well as the governance rules for companies listed on the New York Stock Exchange (“NYSE”). These principles are reflected in the structure and composition of our Board of Directors (our “Board”) and in the charters of our Board Committees, and are reinforced through Aetna’s Code of Conduct, which applies to every Aetna employee and every member of the Board.

Aetna’s Corporate Governance Guidelines

Aetna’s Corporate Governance Guidelines (the “Guidelines”) provide the framework for the governance of Aetna. The governance rules for companies listed on the NYSE and those contained in the Sarbanes-Oxley Act of 2002 are reflected in the Guidelines. The Guidelines address the role of the Board (including advising on key strategic, financial and business objectives); the composition of the Board and selection of Directors; the functioning of the Board (including its annual self-evaluation); the Committees of the Board; the compensation of Directors; and the conduct and ethics standards for Directors, including a prohibition against any nonmanagement Director having a direct or indirect material relationship with Aetna and its subsidiaries (collectively, the “Company”) except as authorized by the Board or the Nominating and Corporate Governance Committee (the “Nominating Committee”), and a prohibition against Company loans to, or guarantees of obligations of, Directors and their family members. The Guidelines are available at www.aetna.com/governance.

The Board reviews the Company’s corporate governance practices at least annually. These reviews include a comparison of our current practices to those suggested by various groups or authorities active in corporate governance and to those of other public companies.

2017 Proxy Statement        1

GOVERNANCE OF THE COMPANY

Aetna’s Board of Directors

Aetna’s business and affairs are managed under the direction of the Board. Under Aetna’s By-Laws, the size of the Board may range from 3 to 21 members, with any change to the size of the Board to be designated from time to time by the Board. The Board currently consists of 12 individuals. The Board appoints Aetna’s senior officers, who serve at the discretion of the Board.

Under Aetna’s Articles of Incorporation, at each annual meeting of shareholders, all of the Directors are elected to hold office for a term of one year and until their successors are elected and qualified. Proxies cannot be voted for a greater number of persons than the number of Director nominees named in this Proxy Statement.

As a complement to our annual Board and Committee self-evaluations and as part of the Board’s desire for continuous self-improvement, during 2015 the Board engaged an independent third-party facilitator to conduct individual director interviews. This interview process was designed to provide Directors an opportunity to share valuable feedback with each other with the goal of maximizing individual effectiveness. The Board expects to continue the use of a third-party facilitator periodically in the future.

Director Elections — Majority Voting Standard

Aetna’s Articles of Incorporation provide for majority voting in uncontested elections of Directors. Under the Articles of Incorporation, a Director nominee will be elected if the number of votes cast “for” the nominee exceeds the number of votes cast “against” the nominee. An abstention will not have any effect on the outcome of the election. In contested elections, those in which there are more candidates for election than the number of Directors to be elected and one or more candidates have been properly proposed by shareholders, the voting standard will be a plurality of votes cast. Under Pennsylvania law, if an incumbent Director nominee does not receive a majority of the votes cast in an uncontested election, the incumbent Director will continue to serve on the Board until his or her successor is elected and qualified. To address this situation, the Guidelines require any incumbent Director nominee in an uncontested election who receives more “against” votes than “for” votes to promptly submit his or her resignation for consideration by the Nominating Committee. The Nominating Committee is then required to recommend to the Board the action to be taken with respect to the resignation, and the Board is required to act on the resignation, in each case within a reasonable period of time. Aetna will disclose promptly to the public each such resignation and decision by the Board. New nominees not already serving on the Board who fail to receive a majority of votes cast in an uncontested election will not be elected to the Board in the first instance.

Director Retirement Age

The Nominating Committee regularly assesses the appropriate size and composition of the Board and, among other matters, whether any vacancies on the Board are expected due to retirement or otherwise. The current Director retirement age is 76. Each year, the Nominating Committee considers the characteristics and performance of each individual Director candidate as part of its nomination process, regardless of the candidate’s age.

2        Aetna Inc.

GOVERNANCE OF THE COMPANY

Executive Sessions

Aetna’s nonmanagement Directors meet in regularly scheduled executive sessions without management present at every regular Aetna Board meeting. During 2016, the nonmanagement Directors, met seven times to discuss certain Board policies, processes and practices, the performance and proposed performance-based compensation of the Chairman and Chief Executive Officer, management succession and other matters relating to the Company and the functioning of the Board. In addition, Aetna’s independent Directors met six times in executive session during 2016 without management present.

Board Leadership Structure and the Lead Director

The Board, assisted by the Nominating Committee, regularly reviews the leadership structure of the Company, including whether the position of Chairman should be held by an independent Director. The Board believes that the decision to combine or separate the positions of Chairman and Chief Executive Officer is highly dependent on the strengths and personalities of the personnel involved and must take into account current business conditions and the environment in which the Company operates. The Board also strongly believes Mr. Bertolini, who continues to serve as Chief Executive Officer, is a successful leader of the Board and an effective bridge between the Directors and Company management. While the Board has decided to keep the roles of Chairman and Chief Executive Officer combined at this time, the Board also has taken steps to ensure that it effectively carries out its responsibility for independent oversight of management. These steps include the election of a Lead Director (with comprehensive and clearly delineated duties); the scheduling at every regular Board meeting of an executive session of the independent Directors (without Mr. Bertolini or other management attendees present); and assuring that substantially all of the nonmanagement Directors are independent. In addition, each Board Committee meets regularly in executive session without management attendees.

The duties of the Lead Director include the following:
●	presiding at all meetings of the Board at which the Chairman is not present, including executive sessions of the independent Directors;
●	approving meeting agendas and schedules to assure there is sufficient time for discussion of all agenda items;
●	approving information sent to the Board;
●	calling special meetings of the Board (including meetings of the independent Directors); and
●	making himself or herself available as appropriate for consultation and direct communication upon the reasonable request of a major shareholder.

Edward J. Ludwig, an independent Director, has served as the Lead Director since February 24, 2012. The Lead Director is appointed annually.

Communications with the Board

To contact Aetna’s Chairman or its Lead Director or to send a communication to the entire Board you may contact:

Mark T. Bertolini
Chairman and Chief Executive Officer
Aetna Inc.
151 Farmington Avenue
Hartford, CT 06156 or Edward J. Ludwig
Lead Director
P.O. Box 370205
West Hartford, CT 06137-0205

Communications sent to Aetna’s Chairman will be delivered directly to him. All communications to the Lead Director or addressed to the nonmanagement Directors will be kept confidential and forwarded directly to the Lead Director. Items that are unrelated to a Director’s duties and responsibilities as a Board member, such as junk mail, may be excluded by the Corporate Secretary.

Director Independence

The Board has established guidelines (“Director Independence Standards”) to assist it in determining Director independence. In accordance with the Director Independence Standards, the Board must determine that each independent Director has no material relationship with the Company other than as a Director and/or a shareholder of the Company. Consistent with the NYSE listing standards, the Director Independence Standards specify the criteria by which the independence of our Directors will be determined, including guidelines for Directors and their immediate family members with respect to past employment or affiliation with the Company or its external auditor. The Director Independence Standards are available at www.aetna.com/about-us/corporate-governance.html.

Pursuant to the Director Independence Standards, the Board undertook its annual review of Director independence in February 2017. The purpose of this review was to determine whether any nonmanagement Director’s relationships or transactions are inconsistent with a determination that the Director is independent. During this review, the Board considered transactions and relationships between each Director or any member of his or her immediate family (or any entity of which a Director or an immediate family member is a partner, major shareholder or officer) and the Company. The Board also considered whether there were any transactions or relationships between Directors or any member of their immediate family with members of the Company’s senior management or their affiliates.

As a result of this review, the Board affirmatively determined in its business judgment that each of Fernando Aguirre, Frank M. Clark, Betsy Z. Cohen, Molly J. Coye, M.D., Roger N. Farah, Jeffrey E. Garten, Ellen M. Hancock, Richard J. Harrington, Edward J. Ludwig, Joseph P. Newhouse and Olympia J. Snowe, each of whom also is standing for election at the Annual Meeting, is independent as defined in the NYSE listing standards and under Aetna’s Director Independence Standards and that any relationship with the Company (either directly or as a partner, major shareholder or officer of any organization that has a relationship with the Company) is not material under the independence thresholds contained in the NYSE listing standards and under Aetna’s Director Independence Standards. In 2016, the Board affirmatively determined that Barbara Hackman Franklin was independent under both such standards and that any such relationship with the Company was not material. Ms. Franklin retired from the Board in May 2016.

In determining that each of the nonmanagement Directors is independent, the Board considered that the Company in the ordinary course of business sells products and services to, purchases products and services from, and/or makes charitable contributions to companies and other entities at which some of our Directors or their immediate family members are or have been officers and/or significant equity holders or have certain other relationships. Specifically, the Board considered the existence of and approved the transactions described in the tables below, all of which were made in the ordinary course of business, on terms and conditions substantially similar to those with unrelated third parties, and which the Board believes were in, or not inconsistent with, the best interests of the Company. The aggregate amounts paid to or received from these companies or other entities in each of the last three years did not exceed the threshold in the Director Independence Standards (i.e., the greater of $1 million or 2% of the other company’s consolidated gross revenues) for 2016.

GOVERNANCE OF THE COMPANY

Meeting Attendance

The Board and its Committees meet throughout the year on a set schedule and also hold special meetings from time to time, as appropriate. During 2016, the Board met twelve times. The average attendance of Directors at all meetings during the year was 96.6%, and no Director attended fewer than 75% of the aggregate number of Board and Committee meetings that he or she was eligible to attend. It is the policy of the Board that all Directors should be present at Aetna’s Annual Meeting of Shareholders. Eleven of the twelve Directors then in office and standing for election attended Aetna’s 2016 Annual Meeting of Shareholders.

Aetna’s Code of Conduct

Aetna’s Code of Conduct applies to every Aetna employee and to every member of the Board and is available at www.aetna.com/governance. The Code of Conduct is designed to ensure that Aetna’s business is conducted in a consistently legal and ethical manner. The Code of Conduct includes policies on employee conduct, conflicts of interest and the protection of confidential information and requires compliance with all applicable laws and regulations. Aetna will disclose any amendments to the Code of Conduct or waivers of the Code of Conduct relating to Aetna’s Directors, executive officers and principal financial and accounting officers or persons performing similar functions on its website at www.aetna.com/governance within four business days following the date of any such amendment or waiver. To date, no such waivers have been requested or granted.

Related Party Transaction Policy

Under Aetna’s Code of Conduct, the Board or an independent Committee reviews any potential conflicts between the Company and any Director. In addition, the Board has adopted a written Related Party Transaction Policy (the “Policy”) which applies to Directors, executive officers, significant shareholders and their immediate family members (each a “Related Person”). Under the Policy, all transactions involving the Company in which a Related Person has a direct or indirect material interest must be reviewed and approved (1) by the Board or the Nominating Committee if involving a Director, (2) by the Board or the Audit Committee if involving an executive officer or (3) by the Board if involving a significant shareholder. The Board or appropriate Committee considers relevant facts and circumstances, which may include, without limitation, the commercial reasonableness of the terms, the benefit to the Company, opportunity costs of alternate transactions, the materiality and character of the Related Person’s direct or indirect interest, and the actual or apparent conflict of interest of the Related Person. A transaction may be approved if it is determined, in the Board’s or appropriate Committee’s reasonable business judgment, that the transaction is in, or not inconsistent with, the best interests of the Company and its shareholders, and considering the interests of other relevant constituents, when deemed appropriate. Determinations of materiality are made by the Board or appropriate Committee, as applicable.

GOVERNANCE OF THE COMPANY

BOARD’S ROLE IN THE OVERSIGHT OF RISK

The Company relies on its comprehensive enterprise risk management (“ERM”) process to aggregate, monitor, measure and manage risk. The ERM process is dynamic and ongoing. It is designed to identify the most important risks facing the Company as well as to prioritize those risks in the context of the Company’s overall strategy. The Company’s ERM team is led by the Company’s Chief Enterprise Risk Officer, who is also the Company’s Chief Financial Officer. In collaboration with the Audit Committee and the Board, the ERM team annually conducts a risk assessment of the Company’s businesses. All of our key business leaders are involved in the risk assessment process. The risk assessment is presented to, and reviewed by, the Audit Committee and, after reflecting the Audit Committee’s views, the list of enterprise risks is then reviewed and approved by the Board. As part of their reviews, the Audit Committee and the Board consider the internal governance structure for managing risks, and the Board assigns responsibility for ongoing oversight of each identified risk to a specific Committee of the Board or to the Board. Discussions of assigned risks are then incorporated into the agenda for each Committee (or the Board) throughout the year. Risk management is ongoing, and the importance assigned to identified risks can change and new risks can emerge during the year as the Company develops and implements its strategy. Consequently, our Chief Enterprise Risk Officer, in consultation with the Chairman and Chief Executive Officer, monitors risk management and mitigation activities across the organization throughout the year and reports periodically to the Audit Committee and the Board concerning the Company’s risk management profile and activities. As a result, we believe having the same individual serve as both Chairman and Chief Executive Officer assists the Board in performing its risk oversight function because the Chairman and Chief Executive Officer is directly involved in the Company’s ERM process. The Audit Committee also meets regularly in private sessions with the Company’s Chief Enterprise Risk Officer.

Board and Committee Membership; Committee Descriptions

Committee on Compensation and Talent Management
	Roger N. Farah
	Chair
The Board has determined in its business judgment that all members of the Compensation Committee meet the independence requirements set forth in the NYSE listing standards and in Aetna’s Director Independence Standards. The Compensation Committee is directly responsible for reviewing and approving the corporate goals and objectives relevant to Chief Executive Officer and other executive officer compensation; evaluating the Chief Executive Officer’s and other executive officers’ performance in light of those goals and objectives; and establishing the Chief Executive Officer’s and other executive officers’ compensation levels based on this evaluation. The Chief Executive Officer’s compensation is determined after reviewing the Chief Executive Officer’s performance and consulting with the nonmanagement Directors of the Board. The Compensation Committee also evaluates and determines the compensation of the Company’s executive officers and other senior positions identified by the Compensation Committee and oversees the compensation and benefit plans, policies and programs of the Company. The Compensation Committee consults with the Chief Executive Officer regarding the compensation of all executive officers other than the Chief Executive Officer, but the Compensation Committee does not delegate its authority with regard to these executive compensation decisions. The Compensation Committee reviews and approves executive compensation philosophy and strategy, including peer group and target compensation positioning.

The Compensation Committee is directly responsible for the appointment, compensation and oversight of the work of any such compensation consultant, legal or other advisor retained by the Committee used to assist the Compensation Committee and has the sole authority to approve each consultant’s fees and other retention terms. When selecting a compensation consultant, legal or other advisor, the Committee considers (i) the provision of other services to the Company; (ii) the amount of fees paid to the advisor as a percentage of the advisor’s total revenue; (iii) the policies and procedures of the advisor’s employer that are designed to prevent conflicts of interest; (iv) any business or personal relationship between the advisor and a member of the Committee; (v) any Company stock owned by the advisor; (vi) any business or personal relationship of the advisor and an executive officer of the Company; and (vii) any other factor deemed relevant to the advisor’s independence from management. In accordance with this authority, the Compensation Committee engaged Meridian Compensation Partners (“Meridian”) as independent outside compensation consultants to advise the Compensation Committee on all matters related to Chief Executive Officer and other executive compensation. The Company may not engage Meridian for any services other than in support of the Compensation Committee without the prior approval of the Chair of the Compensation Committee. Meridian also advises the Nominating Committee regarding Director compensation. The Company does not engage Meridian for any services other than in support of these Committees.

GOVERNANCE OF THE COMPANY

Consideration of Director Nominees

●	Shareholder Nominees. The Nominating Committee will consider properly submitted shareholder nominations for candidates for membership on the Board as described below under “Director Qualifications” and “Identifying and Evaluating Nominees for Director.” Any shareholder nominations of candidates proposed for consideration by the Nominating Committee should include the nominee’s name and qualifications for Board membership, and otherwise comply with applicable rules and regulations, and should be addressed to:
	Corporate Secretary Aetna Inc. 151 Farmington Avenue, RW61 Hartford, CT 06156
	In addition, Aetna’s By-Laws permit shareholders to nominate Directors for consideration at a meeting of shareholders at which one or more Directors are to be elected. For a description of the process for nominating Directors in accordance with Aetna’s By-Laws, see “Can I Propose Actions for Consideration at Next Year’s Annual Meeting of Shareholders or Nominate Individuals to Serve as Directors?” beginning on page 84.

●	Director Qualifications. The Nominating Committee Charter sets out the criteria weighed by the Nominating Committee in considering all Director candidates, including shareholder-identified candidates. The criteria are re-evaluated periodically and currently include: the relevance of the candidate’s experience to the business of the Company; enhancing the diversity of the Board; the candidate’s independence from conflict or direct economic relationship with the Company; and the candidate’s ability to attend Board meetings regularly and devote an appropriate amount of effort in preparation for those meetings. It also is expected that nonmanagement Directors nominated by the Board are individuals who possess a reputation and hold positions or affiliations befitting a director of a large publicly held company, and are actively engaged in their occupations or professions or are otherwise regularly involved in the business, professional or academic community.
●	Diversity. The Nominating Committee believes that, in addition to the traditional concepts of diversity (e.g., gender, race and ethnicity), it also is important to achieve a diversity of knowledge, experience and capabilities on the Board that supports the Company’s strategic direction. The Nominating Committee and the Board believe that having a Board of Directors with a broad background of skills, perspectives and experiences is crucial to enhancing the quality of Board decision-making and governance. As a result, identifying Director candidates with diverse experiences, qualifications and skills that complement those already present on the Board has been and will continue to be central to the Nominating Committee’s Director nomination process. Although the Board does not have a formal diversity policy, our Directors come from many different fields, including academia, technology, retail, service, consumer products, not-for-profit, public service and regulatory. Our Director Nominees for 2017 include four women, one Latino male and one African American male.
	The specific experiences, qualifications, attributes and skills that the Nominating Committee and the Board believe each Nominee possesses are set forth below each Nominee’s biography beginning on page 14.

● Identifying and Evaluating Nominees for Director. The Nominating Committee uses a variety of methods to identify and evaluate nominees for Director. In recommending Director nominees to the Board, the Nominating Committee solicits candidate recommendations from its own members, other Directors and management. It also may engage the services and pay the fees of a professional search firm to assist it in identifying potential Director nominees. The Nominating Committee also reviews materials provided by professional search firms or other parties in connection with its consideration of nominees. The Nominating Committee regularly assesses the appropriate size of the Board and whether any vacancies on the Board are expected due to retirement or otherwise. If vacancies are anticipated, or otherwise arise, the Nominating Committee considers whether to fill those vacancies and, if applicable, considers various potential Director candidates. These candidates are evaluated against the current Director criteria at regular or special meetings of the Nominating Committee and may be considered at any point during the year. As described above, the Nominating Committee will consider properly submitted shareholder nominations for candidates for the Board. Following verification of the shareholder status of the person(s) proposing a candidate, a shareholder nominee will be considered by the Nominating Committee at a meeting of the Nominating Committee. If any materials are provided by a shareholder in connection with the nomination of a Director candidate, such materials are forwarded to the Nominating Committee.

GOVERNANCE OF THE COMPANY

The Board and the Nominating Committee each considered the characteristics and performance of the individual Directors standing for election to the Board at the Annual Meeting against the foregoing criteria, and, to the extent applicable, reviewed the impact of any change in the principal occupations of all Directors during the last year. Upon completion of its review process, the Nominating Committee reported to the Board its conclusions and recommendations for nominations to the Board, and the Board nominated the 12 Director nominees named in this Proxy Statement based on those recommendations.

I. ELECTION OF DIRECTORS

PROPOSAL I	Election of 12 Directors
	The Board, acting upon the recommendation of the Nominating Committee, has nominated the 12 Directors currently serving for re-election as Directors. Each nominee who receives more “for” votes than “against” votes cast at the Annual Meeting will be elected a Director.
	✓	The Board recommends a vote FOR each of the 12 Director nominees.

This year, Aetna will nominate 12 individuals for election as Directors at the Annual Meeting (the “Nominees”) to replace the current Board. The terms of office for the Directors elected at the Annual Meeting will run until the next annual meeting and until their successors are duly elected and qualified. The Nominating Committee recommended the 12 Nominees for nomination by the Board. Based on that recommendation, the Board nominated each of the Nominees for election at the Annual Meeting.

All Nominees are currently Directors of Aetna. The following pages list the names and ages of the Nominees as of the date of the Annual Meeting, the year each first became a Director of Aetna or one of its predecessors, the principal occupation of each Nominee as of March 17, 2017, the publicly traded company directorships and certain other directorships held by each Nominee for the past five years, a brief description of the business experience of each Nominee for at least the last five years, and the specific experience, qualifications, attributes and skills that each Nominee possesses. The specific experience, qualifications, attributes and skills listed below for each Nominee are in addition to the individual qualifications required for all nominees as outlined under “Consideration of Director Nominees-Director Qualifications” on page 11.

Each of the 12 individuals listed below (or such lesser number if the Board has reduced the number of Directors to be elected at the Annual Meeting as described on page 84 under “What If a Director Nominee Is Unwilling or Unable to Serve?”) who receives more “for” votes than “against” votes cast at the Annual Meeting will be elected a Director. In addition, as described in more detail on page 2 under “Director Elections — Majority Voting Standard,” Aetna’s Corporate Governance Guidelines require any incumbent nominee for Director in an uncontested election who receives more “against” votes than “for” votes to promptly submit his or her resignation for consideration by the Nominating Committee. The Nominating Committee and the Board are then required to act on the resignation, in each case within a reasonable period of time.

The Board recommends a vote FOR each of the 12 Nominees. If you complete the enclosed proxy card, unless you direct to the contrary on that card, the shares represented by that proxy card will be voted FOR the election of all 12 Nominees.

I. ELECTION OF DIRECTORS

Director Compensation Philosophy and Elements

Each year, the Nominating Committee reviews compensation for nonmanagement Directors and makes recommendations regarding the prospective level and composition of Director compensation to the Board for its approval.

The Nominating Committee’s goal is to develop a compensation program that:

● Attracts and retains qualified Directors;

● Recognizes Directors’ critical contributions; and

● Aligns, through the offering of stock-based compensation, the interests of Aetna’s Directors with the long-term interests of our shareholders.

As part of their review, the Nominating Committee and the Board consider, among other factors, the Director compensation practices at a comparative group of public companies (the “comparative group”), based on market comparison studies prepared by Meridian, an outside consultant.

The primary elements of Aetna’s Director compensation program are annual cash retainer fees and annual restricted stock unit (“RSU”) awards. Directors also receive certain benefits. Directors who are officers of Aetna receive no additional compensation for membership on the Board or any of its Committees.

Director Stock Ownership Guidelines

The Board has established Director Stock Ownership Guidelines under which each nonmanagement Director is required to own, within five years of joining the Board, a specified dollar value of Aetna common shares, par value $.01 per share (“Common Stock”), or stock units having a dollar value equal to $500,000. At March 17, 2017, all of Aetna’s nonmanagement Directors were in compliance with these guidelines.

Aetna’s Code of Conduct prohibits Directors from engaging in hedging strategies using puts, calls or other types of derivative securities based on the value of the Common Stock.

2016 Nonmanagement Director Compensation

On September 24, 2015 and December 3, 2015 the Nominating Committee and Meridian reviewed a director compensation study prepared by Meridian, and on December 4, 2015, the Board approved the Director compensation package for nonmanagement Directors for 2016. The Board set the total value of target per-Director compensation for 2016 at approximately $289,415 consisting of stock-based compensation, cash and benefits and excluding the estimated cost of the Charitable Award Program and Aetna Foundation, Inc.’s charitable contribution matching program. The annual Board retainer was increased from $85,000 to $95,000 for 2016. In addition, for 2016, the retainer for the Chair of the Audit Committee was increased from $20,000 to $25,000, while the retainer for each Audit Committee member remained at $10,000. Chair retainers were increased from $15,000 to $25,000 for the Compensation Committee, $8,000 to $13,000 for the Investment and Finance Committee and the Medical Affairs Committee, and $10,000 to $15,000 for the Nominating Committee. Committee member retainers remained at $4,000 for the Executive Committee, the Investment and Finance Committee and the Medical Affairs Committee; $5,000 for the Nominating Committee; and $7,500 for the Compensation Committee. The annual retainer for the Lead Director also was increased from $25,000 to $35,000. In addition, the target grant date fair value of annual RSU awards to each Director under the Director Plan was increased from $160,000 to $170,000.

The 2016 Director Compensation table sets forth for 2016 the total compensation of each of the nonmanagement Directors. Actual compensation for any Director, and amounts shown in the 2016 Director Compensation table, may vary by Director due to the Committees on which a Director serves and other factors described in footnote 4 to the 2016 Director Compensation table.

Amounts shown are pre-tax. Directors derive no personal financial or tax benefit from this program.

Additional Director Compensation Information

Director Deferrals

The amounts shown in the “Fees Earned or Paid in Cash” and “Stock Awards” columns of the 2016 Director Compensation table include amounts that were deferred by Directors during 2016 under the Director Plan. Under the Director Plan, nonmanagement Directors may defer payment of some or all of their annual retainer fees, vested RSUs and dividend equivalents paid on stock units to an unfunded stock unit account or unfunded interest account until after they have resigned or retired (as defined in the Director Plan) from the Board or elect to diversify their deferred stock unit holdings as described below.

During the period of deferral, amounts deferred to the stock unit account track the value of the Common Stock and earn dividend equivalents. During the period of deferral, amounts deferred to the interest account accrue interest pursuant to a formula equal to the rate of interest paid from time to time under the fixed interest rate fund option of Aetna’s 401(k) Plan (the “401(k) Plan”), which was 2.05% for the period January to March 2016; 2.10% for the period April to June 2016; 2.10% for the period July to October 2016; and 2.15% for the period October to December 2016.

Under the Director Plan, beginning at age 68, Directors are allowed to make an annual election to diversify up to 100% of their voluntary deferrals into the stock unit account out of stock units and into an interest account. During 2016, no Director made such a diversification election. Directors who make a diversification election remain subject to the Board’s Director Stock Ownership Guidelines.

I. ELECTION OF DIRECTORS

Restricted Stock Unit Awards

On May 20, 2016, Aetna granted each nonmanagement Director then in office 1,537 RSUs under the Director Plan. The full grant date fair value of the RSUs granted to each nonmanagement Director was $170,054. The RSUs vest in quarterly increments over a one-year period beginning May 20, 2016, and are payable at the end of the one-year period in shares of Common Stock or can be deferred under the Director Plan to a stock unit account or an interest account as described above. The RSUs granted to a nonmanagement Director will vest immediately if the Director ceases to be a Director because of death, disability, retirement or acceptance of a position in government service. All RSUs granted to nonmanagement Directors also will vest upon a change in control of Aetna (as defined in the Director Plan). The unvested RSUs granted to nonmanagement Directors do not earn dividend equivalents, have no voting rights and are not transferable.

Director Charitable Award Program

Prior to January 26, 2008, Aetna maintained a Director Charitable Award Program (the “Program”) for nonmanagement Directors serving on the Board. After a review of the Program and competitive practices, the Board decided to close the Program, and any Director who first joins the Board after January 25, 2008 is not eligible to participate. However, to recognize pre-existing commitments, the Program remains in place for Directors serving prior to that date. Under the Program, Aetna will make a charitable contribution of $1 million in ten equal annual installments allocated among up to five charitable organizations recommended by a participating Director once he or she reaches age 72. For Mr. Farah, who joined the Board in 2007, contributions would occur once he reaches age 75. The Program may be funded indirectly by life insurance on the lives of the participating Directors. Messrs. Aguirre and Harrington and Senator Snowe are not eligible to participate in the Program because they joined the Board after the Program closed to new Directors.

Beneficiary organizations recommended by Directors must be, among other things, tax exempt under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the “Code”). Donations Aetna ultimately makes are expected to be deductible from Aetna’s taxable income for purposes of U.S. federal and other income taxes. Directors derive no personal financial or tax benefit from the Program, since all insurance proceeds and charitable deductions accrue solely to Aetna.

The Program values included in footnote 4 to the 2016 Director Compensation table represent an estimate of the present value of the total annual economic net cost of the Program, pre-tax, for current and former Directors, allocated equally among the Directors still participating in the Program. The present value calculation considers estimates of (a) premiums paid on whole life insurance policies purchased with respect to certain of the Directors to fund part of the Program; (b) the expected future charitable contributions to be paid by Aetna on behalf of current and former Directors; (c) expenses associated with administering the Program; and (d) the expected future proceeds from such whole life insurance policies which are, in turn, based on expected mortality, as well as assumptions related to future investment returns of the policies.

Other Benefits

Aetna provides $150,000 of group life insurance and $100,000 of business travel accident insurance (which includes accidental death and dismemberment coverage) for its nonmanagement Directors. Optional medical, dental and long-term care coverage for nonmanagement Directors and their eligible dependents also is available to Directors at a cost similar to that charged to Aetna employees and may be continued into retirement by eligible Directors.

Aetna also reimburses nonmanagement Directors for the out-of-pocket expenses they incur that pertain to Board membership, including travel expenses incurred in connection with attending Board, Committee and shareholder meetings, and for other Aetna business-related expenses (including the business-related travel expenses of spouses if they are specifically invited to attend an event).

From time to time, Aetna also may transport Directors to and from Board meetings or Directors and their guests to and from other Aetna business functions on Company aircraft.

2017 Nonmanagement Director Compensation

On September 29, 2016 and December 1, 2016 the Nominating Committee and Meridian reviewed a director compensation study prepared by Meridian, and on December 2, 2016, the Board approved the Director compensation package for nonmanagement Directors for 2017. The Board did not change the total value of target per-Director compensation for 2017, and kept it at approximately $289,415 consisting of stock-based compensation, cash and benefits and excluding the estimated cost of the Charitable Award Program and Aetna Foundation, Inc.’s charitable contribution matching program. The annual Board retainer remains at $95,000 for 2017. For 2017, Chair retainers remain at $25,000 for the Audit Committee, $25,000 for the Compensation Committee, $13,000 for the Investment and Finance Committee and the Medical Affairs Committee, and $15,000 for the Nominating Committee. Committee member retainers remain at $10,000 for the Audit Committee; $7,500 for the Compensation Committee; $4,000 for the Executive Committee, the Investment and Finance Committee and the Medical Affairs Committee; and $5,000 for the Nominating Committee. The annual retainer for the Lead Director remains at $35,000. In addition, the target grant date fair value of annual RSU awards to each Director under the Director Plan continues to be $170,000.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires our Directors, our executive officers and certain other persons to file reports of holdings and transactions in our Common Stock with the SEC. Based on our records and other information, we believe that during our fiscal year ended December 31, 2016, our Directors and executive officers timely met all applicable SEC filing requirements, except that one report covering one transaction (a charitable gift) was filed late by Mr. Bertolini. In addition, one Form 4 filed by Francis S. Soistman, Jr. was amended after it was filed to reflect a transfer of funds out of the employer stock fund in the 401(k) Plan. That transaction, which involved 193 shares, was inadvertently excluded from the filed form.

COMPENSATION DISCUSSION AND ANALYSIS

I.  2016 — A Year of Strong Operating Performance and Effective Execution of Our Strategy

A. 2016 Company Performance At-a-Glance

Total Shareholder Return: 16%	Net Income per Share: $6.41	Operating earnings per share: $8.23	Total Revenue and Operating Revenue (each): $63 billion	Continued Dividend of $1.00 per share (annual)
Three-year cumulative total shareholder return of 86%	5% decrease in net income per share from 2015 primarily due to increased restructuring costs and Humana transaction and integration related costs	7% increase in operating earnings per share over 2015	Nearly 5% increase over 2015 (each)	In February 2017, the Company announced an increased dividend of $2.00 per share (annualized)

Net income refers to net income attributable to Aetna reported in Aetna’s GAAP Consolidated Statements of Income. Unless otherwise indicated, all references in this Proxy Statement to net income, net income per share, operating earnings, and operating earnings per share are based on net income attributable to Aetna, which excludes amounts attributable to non-controlling interests. Operating earnings per share, operating revenue, pre-tax operating margin, adjusted operating expense ratio and adjusted selling, general and administrative expense ratio are non-GAAP financial measures. Refer to Annex A to this Proxy Statement for a reconciliation of these and other non-GAAP financial measures to the most directly comparable GAAP measures.

B.  2016 Company Performance and Related Impact on Compensation Decisions

The Company’s financial performance in 2016 was strong and continued to reflect the Company’s attention to effective execution of our strategy. During 2016, the Company delivered:

● Strong Shareholder Returns. During 2016, our stock price increased 15% from $108.12 on December 31, 2015 to $124.01 on December 31, 2016. On March 17, 2017, our stock closed at $131.80. Our total shareholder return for 2016 was 16%, and our three-year cumulative total shareholder return was 86%.

Total Shareholder Return

2017 Proxy Statement        29

COMPENSATION DISCUSSION AND ANALYSIS

● Solid Earnings. For 2016, we reported net income per share of $6.41 compared to $6.78 in 2015, a 5 percent decrease. We reported 2016 operating earnings per share of $8.23, a 7% increase over 2015, consistent with our long-term targeted range. The year-over-year decline in net income per share was primarily driven by an increase in restructuring costs, higher Humana Inc. (“Humana”) transaction related costs and the favorable impact of litigation related proceeds recorded in 2015. The year-over-year increase in operating earnings per share represents solid earnings growth, despite lack of share repurchases during the year and significant pressure from our Affordable Care Act compliant products.

Net Income per Share

Operating Earnings per Share

● Strong Revenue. In 2016, we reported annual total revenue and operating revenue of $63 billion (each), a nearly 5% increase over 2015 (each). This growth in total revenue and operating revenue was driven primarily by higher health care premium yields and membership growth in the Government business in our Health Care segment.

● Dividend. In 2016, we maintained our quarterly cash dividend, reflecting continued confidence in our strategy and our commitment to enhancing total return for our shareholders. Our merger agreement with Humana restricted our ability to increase our dividend during the term of the agreement, which ended on February 14, 2017. On February 17, 2017, the Company announced that it will increase its quarterly dividend to $.50 per share ($2.00 annualized). The prior 5-year dividend growth rate, exclusive of the 2017 increase, was approximately 67%.

Dividend Payments*

● Medical Membership. In 2016, we ended the year with 23.1 million medical members, consistent with our year-end membership projections.

● After-tax Net Income Margin. Aetna reported a 2016 after-tax net income margin of 3.6%, a 40 basis point decrease compared to 2015, primarily due to an increase in restructuring costs and Humana-related transaction and integration related costs.

● Pre-tax Operating Margin in High Single Digits. Aetna reported a 2016 pre-tax operating margin of 8.3%, consistent with our high single-digit target.

● Total Company Expense Ratio. Our full year 2016 total company expense ratio was 19.1%, consistent with 2015.

● Adjusted Operating Expense Ratio. Our full year adjusted operating expense ratio was 18.1%, an 80 basis point improvement over 2015. This year-over-year improvement resulted from our disciplined focus on managing costs while growing operating revenue.

● Progress on Strategic Initiatives. While we are disappointed in the United States District Court’s decision to block our proposed acquisition of Humana (the “Humana acquisition”) and the resulting

COMPENSATION DISCUSSION AND ANALYSIS

termination of the transaction, our commitment to our strategy has never been stronger. We continue to make investments in digital tools and differentiated care models to provide our members with access to simple, high quality, affordable products that help them achieve their best health. These investments position the Company to continue to be part of the solution in the evolving health care landscape. In 2016, we delivered 45% of our medical costs through value-based arrangements and launched new consumer-centric insurance products in select geographies, often backed by accountable care organizations or value-based network agreements.

The Company’s executive pay decisions reflect the alignment between executive compensation and Company performance:

● Annual Bonus Payments Above Target. Our annual bonus program (“ABP”), which for 2016 was weighted 70% on annual financial metrics and 30% on quantitative constituent measures, was funded at 114.7% of target.

● CEO Special Retention PSU. The Compensation Committee determined that the special retention PSU granted to Mr. Bertolini in August 2013 vested below target level (74.6%) based on Company performance against the stretch cumulative three-year pre-tax operating income goal (excluding net investment income) set at the time the grant was awarded. Under the terms of the award, the special retention PSU was deferred to an unfunded deferred stock unit account which is payable to Mr. Bertolini six months following his termination of employment.

● CEO Special Performance Stock Appreciation Right vested below target. The Compensation Committee determined that the 2013 Performance Stock Appreciation Rights (“PSARs”) granted to Mr. Bertolini vested below target level (83.3%) based on Company performance against the three-year relative total shareholder return performance goal set at the time the award was granted.

C.  2016 “Say on Pay” Vote/Compensation Plan Design Changes

At our 2016 annual meeting, 93.7% of the votes cast at the meeting supported the Company’s 2015 Named Executive Officer (“NEO” or “Named Executive Officer”) compensation, reflecting strong concurrence with the Company’s executive compensation programs. Annually, the Compensation Committee reviews trends and best practices in executive compensation and related governance areas. The Compensation Committee also considers the alignment between the current compensation programs and the Company’s business strategy. Based on this review and consideration, and given this solid shareholder vote supporting our executive compensation programs, the Compensation Committee did not make any material changes to the executive compensation program design for 2016.

II.  Objectives of Our Executive Compensation Program

An understanding of our executive compensation program begins with the program objectives. These include:

● Aligning the interests of our executives and shareholders. We align the interests of our executives with those of our shareholders through equity-based compensation that is settled in shares of Common Stock and executive share ownership and share retention requirements.

● Linking rewards to performance. We implement a pay-for-performance philosophy by tying a significant portion of our executives’ compensation to achieving financial and quantitative constituent goals that are linked to the Company’s business strategy and each executive’s contributions towards achieving those goals.

● Offering competitive compensation. We offer an executive compensation program that is competitive and that helps us attract, motivate and retain top performing executives in the highly competitive global market for health care talent.

We continue to believe that a significant portion of executive compensation should be variable and based on stock price change and meeting or exceeding defined performance goals (i.e., “at risk”). Our program meets this goal by delivering compensation in the form of equity and other performance-based awards.

Below is a summary of the Compensation Committee’s compensation decisions for Mr. Bertolini:

● 2016 Compensation Opportunity

— Mr. Bertolini’s 2016 total direct compensation opportunity, $17.3 million at target, was at the 75^th percentile of the chief executive officer pay of the comparison group we use to assess compensation. The Compensation Comparison Group is listed on page 40. The Compensation Committee felt this opportunity and its relative positioning were appropriate in light of Company performance and the fact that Mr. Bertolini continues to be a recognized thought leader who serves as a positive and constructive influence on not only the transformation of the health care system, but also on important social policy issues affecting the Company and our nation.

— Within the total direct compensation opportunity, Mr. Bertolini’s 2016 annual bonus target was set at 300% of his annual base salary. Of this amount, 60% is paid in RSUs which are tied directly to the value of Aetna shares and which vest over three years. The Compensation Committee recognizes that Mr. Bertolini’s annual bonus opportunity is high compared to the annual bonus targets of his peers in the Compensation Comparison Group when viewed in isolation. However, when this bonus opportunity was first established on his appointment as CEO, there was a corresponding

32        Aetna Inc.

COMPENSATION DISCUSSION AND ANALYSIS

reduction to Mr. Bertolini’s annual long-term incentive equity grant value to keep his total compensation levels at an appropriate market level. This change in mix of pay opportunity, coupled with the additional vesting required for the equity portion of the annual bonus award, was made to more directly align Mr. Bertolini’s total direct compensation opportunity with the Company’s annual financial performance, while continuing the focus on creation of long-term shareholder value and retention.

—

Mr. Bertolini’s 2016 long-term incentive opportunity was set at $12.4 million. This grant was delivered 70% in SARs ($8.69 million) and 30% in PSUs ($3.75 million). The SARs and PSUs granted in 2016 are described on page 34. The SARs vest in three substantially equal annual installments beginning on February 19, 2017, and the PSUs will vest 36 months from the grant date, in each case subject to Mr. Bertolini’s continued employment and, with respect to PSUs, Company performance.

● Compensation Decisions for 2016

— Base Salary. Mr. Bertolini’s salary was increased by 20% in 2016. Mr. Bertolini’s salary had not been adjusted since his appointment as CEO in November 2010. The Compensation Committee changed Mr. Bertolini’s base salary due to Mr. Bertolini’s performance and due to the fact that it had begun to significantly lag the base salaries of the CEOs in the Compensation Comparison Group.

— Annual Bonus. Mr. Bertolini’s annual bonus for 2016 was determined primarily based on the Company’s financial performance against the ABP goals described in detail beginning on page 35 and paid out at 115% of target. In addition to the strong financial performance, the Compensation Committee and the Board also considered growth in the Company’s individual Medicare membership, expansion of our individual Medicare Advantage footprint (six new states for 2017), our Medicare star ratings performance (best in class among publicly traded peers), and the acceleration of our consumer strategy. While the Company is disappointed in the court decision to block the Humana acquisition and the resulting termination of the transaction, throughout the process the Company was able to exceed its financial objectives and continue its focus on executing its Vision 2020 strategy as a stand-alone company.

— Mr. Bertolini continues to be a recognized thought leader who serves as a positive and constructive influence on not only the transformation of the health care system, but also important social policy issues affecting the Company and our nation. He is the recipient of numerous awards, including being named one of Fortune’s 50 Greatest Leaders and Modern Healthcare’s 100 Most Influential People in Healthcare (ranked 4^th in 2016). His work in recent years to raise the minimum base wage and enhance employee benefits for the Company’s lowest paid employees sparked a wider societal dialogue on these issues. Further, Mr. Bertolini continues to build a strong leadership team which, under his direction, is driving the business and executing the Company’s strategy, while keeping the focus on long-term success. Mr. Bertolini’s annual bonus for 2016 was paid 40% in cash and 60% in RSUs that will vest in three equal annual installments over a 36-month period.

● Long-Term Incentive Awards

— CEO Special Retention PSU. The Compensation Committee determined that the special retention PSU granted to Mr. Bertolini in August 2013 vested below target level (74.6%) based on Company performance against the stretch cumulative three-year pre-tax operating income goal (excluding net investment income) set at the time the award was granted. Under the terms of the award, the special retention PSU was deferred to an unfunded deferred stock unit account which is payable to Mr. Bertolini six months following his termination of employment.

— CEO Special Performance SAR. The Compensation Committee determined that the 2013 PSAR granted to Mr. Bertolini vested below target level (83.3%) based on Company performance against the three-year relative total shareholder return performance goal set at the time the award was granted.

More information about the rationale behind the special retention PSU and PSAR grants is set forth in the Company’s Current Report on Form 8-K filed with the SEC on August 5, 2013.

COMPENSATION DISCUSSION AND ANALYSIS

IV. 2016 Compensation Policies

Elements of the Company’s Executive Compensation Program

The 2016 compensation program for our Named Executive Officers consisted of the following components:

Component	Description	Purpose
Base Salary	Fixed cash compensation based on the executive’s past and potential future performance, scope of responsibilities, experience and competitive market pay practices.	Provide a fixed, baseline level of compensation that is not contingent upon Company performance.
Performance-Based Annual Bonus(1)	Cash payment tied to meeting annual performance goals set for the fiscal year that are tied to the Company’s annual business plan and individual performance.	Motivate executives to achieve superior annual financial and operational performance.
Long-Term Equity Incentives:(2)
PSUs	Performance-based stock units which pay out, if at all, based on the Company’s performance against a three-year adjusted operating earnings per share compound annual growth financial goal. If the goal is met, the PSUs granted in 2016 will vest in a single installment at the end of a 36-month vesting period as described on page 37.	Align achievement of specific multi-year internal financial performance objective with the creation of shareholder value, increase executive stock ownership and provide retention incentives.
RSUs	Time-vested stock units that vest in substantially equal annual installments typically over 36 months.	Align compensation with changes in Company stock price and the creation of shareholder value, and strengthen retention.
SARs	Stock appreciation rights that vest in substantially equal annual installments over 36 months.	Align compensation with changes in Company stock price and the creation of shareholder value.

(1)	A portion of Mr. Bertolini’s 2016 annual bonus was paid in RSUs that vest over 36 months as described on page 32.
(2)	All awards are settled in stock and are subject to stock ownership requirements.

The Company also provides health, welfare and retirement benefits to its employees generally, including its executive officers.

Determining Total Cash and Equity Compensation

We generally set total cash and equity compensation opportunity (including base salary, performance-based annual bonus and long-term incentive equity awards) for senior executives at an amount that is competitively reasonable and appropriate for our business needs and circumstances. For the Named Executive Officers, the Compensation Committee reviews the cash and equity compensation opportunities available to similarly positioned executives of companies in the Compensation Comparison Group. The Compensation Committee also reviews third-party compensation surveys. The third-party compensation surveys are purchased from outside compensation vendors selected by our human resources department, and the data provided by the vendors is reviewed by the Compensation Committee’s independent compensation consultant. The data presented to the Compensation Committee includes a regression analysis (market compensation data adjusted to account for company size based on revenue) where available. The compensation of our Named Executive Officers is compared across the Named Executive Officer group and with the compensation of other senior executives of the Company for internal pay relativity purposes. The Compensation Committee, however, has not established specific internal pay relativity guidelines.

Our compensation program is generally designed to deliver above-median total compensation for above-median performance and below-median total compensation for below-median performance. For executives with compensation opportunities that are more highly variable, including the Named Executive Officers, total cash and equity compensation opportunity may be above the median, but “at risk” amounts are paid only if performance goals are achieved or exceeded. In addition, the value of the equity awards is directly subject to Company stock price change. The Compensation Committee does not formulaically set the target compensation opportunity at a specific level compared to the Compensation Comparison Group. Instead, the Compensation Committee uses the Compensation Comparison Group information as a reference point to make what is ultimately a subjective decision that balances (i) a competitive level of compensation for a position; (ii) the executive’s experience and scope of responsibility; (iii) individual performance; (iv) percent of pay “at risk”; and (v) retention. There is no pre-defined formula that determines which of these factors is more or less important, and the emphasis placed on a specific factor may vary among executive officers and will reflect market conditions and business needs at the time the pay decision is made.

COMPENSATION DISCUSSION AND ANALYSIS

Base Salary

In making annual base salary determinations, the Compensation Committee considers:

● the terms of any employment agreement with the executive;

● the recommendations of our CEO (as to executives other than himself);

● the salary paid to persons in comparable positions in the Compensation Comparison Group;

● the executive’s experience and scope of responsibility; and

● a subjective assessment of the executive’s individual past and potential future contribution to Company results.

Base salary as a percent of total compensation also differs based on the executive’s position and function. Although the Compensation Committee has not established a specific ratio of base salary to total compensation, in general, executives with the highest level and broadest scope of responsibility have the lowest percentage of their compensation fixed as salary and have the highest percentage of their compensation subject to performance-based standards (performance-based annual bonus and long-term incentives).

In 2016, Karen Lynch received a salary increase of 3.5%. This adjustment was consistent with the Company-wide salary increase pool for 2016. Mr. Guertin’s salary was not adjusted because his total direct compensation was at the market median. Due to the recent hire dates of Mr. Loveman and Mr. Sabatino, their salaries were not adjusted. Mr. Bertolini’s 2016 salary increase is described on page 33.

Annual Performance-based Bonuses

Except for a portion of Mr. Bertolini’s bonus (described on page 33), 2016 annual bonuses were paid in cash. All executive officers and managers are eligible to participate in the ABP. The Compensation Committee, after consulting with the Board, establishes specific financial and operational goals at the beginning of each performance year. Annual bonus funding is linked directly to achieving these annual goals. Following the completion of the performance year, the Compensation Committee assesses performance against the pre-established performance goals to determine bonus funding for the year. The ABP goals, described in more detail below, come directly from our strategic and business operating plan approved by the Board. These annual goals were selected to balance the delivery of financial results with the achievement of internal and external constituent goals. The Company believes it is important to consider non-financial, but quantifiable, constituent goals because they focus on our longer-term success and the quality of our brand and reputation. In 2016, the non-financial constituent goals had a 30% weighting.

Under the ABP, if all of the goals are met at the target level in the aggregate, then up to 100% of the target bonus pool is funded. If the goals are exceeded in the aggregate by a sufficient margin, then up to a maximum of 200% of the target bonus pool is funded. At the threshold performance level, 25% of the target bonus pool is funded. The bonus pool is not funded if aggregate performance falls below the threshold level.

For 2016, bonus pool funding under the ABP was determined as set forth below:

Weight	Measure	Threshold	Target	Maximum	Actual Performance	Performance Level	Weighted Points
70%	Financial Performance	25%	100%	200%
50%	Operating earnings per share(1)	$7.71	$8.16	$8.67	$8.23	>target	55.1

Operating earnings per share is a non-GAAP financial measure used in connection with the ABP. Refer to Annex A to this Proxy Statement for a reconciliation of operating earnings per share to the most directly comparable GAAP measure. Operating earnings per share excludes from net income attributable to Aetna (a) net realized capital gains or losses; (b) amortization of other acquired intangible assets; and (c) other items, if any, that neither relate to the ordinary course of our business nor reflect our underlying business performance. These adjustments are established when the target is set at the start of the year.

(2)

Operating revenue is a non-GAAP financial measure used in connection with the ABP. Refer to Annex A to this Proxy Statement for a reconciliation of operating revenue to the most directly comparable GAAP measure. Operating revenue excludes from total revenue (a) net realized capital gains or losses; and (b) other items, if any, that neither relate to the ordinary course of our business nor reflect our underlying business performance. These adjustments are established when the target is set at the start of the year.

(3)	Adjusted selling, general and administrative expenses as a percentage of operating revenue is a non-GAAP financial measure used in connection with the ABP. Refer to Annex A to this Proxy Statement for a reconciliation of adjusted SG&A ratio to the most directly comparable GAAP measure. Adjusted SG&A ratio is calculated by dividing total operating expenses, excluding incentive compensation expense and other items, if any, that neither relate to the ordinary course of our business nor reflect our underlying business performance, by operating revenue. These adjustments are established when the target is set at the start of the year.
(4)	This goal measures consumer experience in 4 new geographies (58% at target) and Medicare Star Ratings (88% at target).
(5)	This goal measures membership growth in accountable care/joint venture organizations (33.8% at target), and customers achieving clinical transformation quality program objectives where the number of accountable care organizations meet or exceed targets (6 at target).
(6)	This goal measures employee engagement and culture determined through responses to the Company’s all-employee survey, as well as performance against diversity initiatives.

After applying the weightings noted above, the Compensation Committee set the Company-wide 2016 ABP bonus pool funding at 114.7% of target. Within this pool funding, the Compensation Committee set actual bonus amounts after conducting a subjective review of each Named Executive Officer’s individual performance for the year against the business unit and qualitative performance goals established at the start of the year and considering Mr. Bertolini’s recommendations (as to executives other than himself). In determining the annual bonus for Mr. Bertolini, the Compensation Committee consulted with the non-management members of the Board. The factors considered in determining individual bonus amounts for the Named Executive Officers are set forth below.

Named Executive Officer	2016 Annual Bonus Target as a Percent of Base Salary(1)		2016 Actual Bonus as a Percent of Target	Individual Discretionary Factors
Mr. Bertolini	300%	(2)	115%	●Described on pages 32-33
Mr. Guertin	110%		111%	●Leadership to drive Company financial results above targets ●Achievement of productivity savings vs. targets ●Talent development ●Compliance
Mr. Loveman	110%		120%	●Leadership to re-align organization around consumer capabilities and building of new care model designed to proactively engage members and help them improve their health ●Exceeding cost reduction targets ●Development of new Company brand, including strategic alliance with Apple Inc. ●Talent development

Mr. Sabatino	100%		110%	●Compliance, including perfect CMS compliance program effectiveness score ●Legal support to execution of ACO/joint venture strategy to support our value-based consumer model ●Robust defense of Humana acquisition

(1)	For NEOs other than Messrs. Bertolini and Sabatino, the target was based on base salary paid during 2016. For Messrs. Bertolini and Sabatino, the target was based on base salary in effect on December 31, 2016.
(2)	Mr. Bertolini’s bonus was paid 40% in cash and 60% in RSUs that vest over 36 months as described on page 32.

Long-term Incentive Equity Awards (SARs and PSUs)

The Company’s 2016 long-term incentive equity award program was delivered in the form of SARs (70%) and PSUs (30%). The objective of the SAR and PSU awards is to advance the longer-term interests of the Company and our shareholders by directly aligning executive compensation with increases in our stock price and providing incentives for executives to meet the specified PSU performance goal set at the time of grant. These awards complement cash incentives tied to annual performance as they motivate executives to increase earnings and shareholder value over time. The 70% allocation to SARs aligns the majority of the long-term incentive value directly with shareholder interest in increasing our stock price; the award has no value if the stock price declines after the award is granted. Because SARs have a 10-year term, this design supports our long-term strategy and emphasizes the creation of long-term shareholder value. The remaining 30% of the long-term incentive value also is tied to the value of our stock and achievement of a specific financial operating goal. The SARs granted in 2016 to the Named Executive Officers vest in substantially equal annual installments over a 36-month period. The PSUs granted in 2016 vest in a single installment at the end of a 36-month period based on attaining the three-year performance goal set at the time of grant. The SAR and PSU awards are settled in Common Stock, net of applicable withholding taxes, in order to reduce shareholder dilution resulting from the awards. The Company does not pay dividend equivalents on unvested equity awards.

36        Aetna Inc.

COMPENSATION DISCUSSION AND ANALYSIS

PSU Performance Goal

The PSUs granted in 2016 vest at 100% if the Company attains a three-year operating earnings per share compound annual growth rate goal. This goal is difficult as it requires the Company to exceed its operating earnings growth objectives for the 2016-2018 performance period. This goal was selected to emphasize the importance of operating earnings growth to our strategic objectives. If this performance goal is met, the PSUs will vest at the end of the 36-month vesting period. At maximum performance, the PSUs vest at 200% of the units granted.

Consideration of Prior Equity Grants When Making Compensation Decisions

In making individual long-term incentive equity award decisions, the Compensation Committee does not specifically take into account prior equity grants or amounts realized on the exercise or vesting of prior equity grants in determining the equity value to be granted. The Company’s philosophy is to pay an annualized market value for the executive’s position, sized according to the performance level of the individual in the position. The Compensation Committee does, however, consider prior equity grants to executives in evaluating the overall design, timing and size of the long-term incentive equity program. In addition, in assessing the recruitment/retention risk for executives, the Compensation Committee considers the value of unvested equity awards.

The effective date of the annual long-term incentive equity grant in 2016 was the stock market trading day of the February Board of Directors and Compensation Committee meetings which followed the release of our annual earnings. The grant price of any annual award is the closing price of our Common Stock on the day the award is granted. The Compensation Committee selected this timing so that the award value reflected our most recent full-year earnings information and outlook. The Compensation Committee also makes grants during the year, primarily in connection with hiring and promotions. Under our policy, off-cycle grants made in connection with hiring are generally effective on the date of hire or the 10^th day of the month following the date of hire.

Health, Welfare and Pension Benefits

To attract and retain employees at all levels, we offer a subsidized health and welfare benefits program that includes medical, dental, life, accident, disability, vacation and severance benefits. Our subsidy for employee health benefits is graduated so that executives pay a higher contribution than more moderately paid employees.

The Company makes the 401(k) plan available to substantially all of our U.S.-based employees, including the Named Executive Officers. We also offer a Supplemental 401(k) Plan (the “Supplemental 401(k) Plan”) to provide benefits above Code contribution limits. There is no Aetna matching contribution under the Supplemental 401(k) Plan. The Company’s Pension Plan (the “Pension Plan”) was frozen as of December 31, 2010, and the Company’s Supplemental Pension Plan (the “Supplemental Pension Plan”) was frozen in January 2007. Interest continues to accrue on outstanding pension cash balance accruals.

Employee Stock Purchase Plan

Our tax-qualified employee stock purchase plan is available to substantially all employees, including the Named Executive Officers. This program allows our employees to buy our Common Stock at a 5% discount to the market price on the purchase date (up to a maximum of $25,000 per year). We offer this program because we believe it is important for all employees to focus on increasing the value of our Common Stock and to have an opportunity to share in our success.

Other Compensation to the Named Executive Officers

The Company provides certain other compensation to the Named Executive Officers (see the All Other Compensation table in footnote 10 to the 2016 Summary Compensation Table on page 43). In the interest of security, with certain exceptions, the Company requires that the CEO use corporate aircraft for personal travel whenever use of the aircraft is not required for a business purpose. Other Named Executive Officers are also permitted to use corporate aircraft for personal travel at the discretion of the CEO. The Compensation Committee believes this practice is reasonable and appropriate given security concerns, efficiency of travel and the demands put on our Named Executive Officers’ time. A financial planning reimbursement, not to exceed $10,000, is provided to Named Executive Officers to assure sound financial planning and tax compliance and to provide more time for the executive to focus on the needs of our business. The Company does not provide any tax gross-ups related to other compensation, including perquisites (other than in connection with relocation benefits provided in connection with an executive’s relocation of residence on behalf of the Company).

Severance Following Termination of Employment

The narrative disclosure and tables beginning on page 51 outline the potential payments that would be made to the Named Executive Officers following their termination of employment under various scenarios. The difference in treatment among the Named Executive Officers is due to the dynamics of negotiation at the time the executive was hired (or promoted), the executive’s position in the Company, market practices and Company policies in effect at the time of entry into an executive’s agreement with the Company.

V. Governance Policies

Governance Highlights
The Company seeks to maintain best practice standards with respect to the oversight of executive compensation. The following policies and practices were in effect during 2016:
✓	Compensation Committee composed solely of independent Directors;
✓	use of an independent compensation consultant retained directly by the Compensation Committee who performs no consulting or other services for management of the Company;
✓	annual review and approval of our executive compensation strategy by the Compensation Committee, including a review of our compensation-related risk;
✓	robust stock ownership requirements for our executive officers and related stock retention policy;
✓	a policy prohibiting all employees, including the Named Executive Officers, from engaging in hedging transactions with respect to equity securities of the Company;
✓	a compensation “claw back” policy that permits the Company to recoup performance-based compensation if the Board determines that a senior executive has engaged in fraud or misconduct that has caused a material restatement of financial results;
✓	no tax gross-up benefits upon a change-in-control; and
✓	no tax gross-ups on perquisites and personal benefits, other than in connection with relocation benefits provided in connection with an executive’s relocation of residence on behalf of the Company.

Many of these policies are described more fully below.

Independent Compensation Consultant

During 2016, the Compensation Committee engaged Meridian to provide independent compensation consulting services to the Compensation Committee. The role of the independent compensation consultant is to ensure that the Compensation Committee has objective information needed to make informed decisions in the best interests of shareholders based on compensation trends and practices in public companies. During the past year, the Compensation Committee requested Meridian to: (i) assist in the development of agendas and materials for Compensation Committee meetings; (ii) provide market data and alternatives to consider for making compensation decisions for the CEO and other executive officers; (iii) assist in the design of the Company’s long-term compensation program; and (iv) keep the Compensation Committee and the Board abreast of changes in the executive compensation environment. Meridian also advised the Nominating Committee regarding Director compensation. In accordance with Compensation Committee policy, the Company does not engage its independent compensation consultant for any services other than in support of these two Committees. Meridian had no relationships with any member of the Compensation Committee or any executive officer of the Company. The Compensation Committee has the sole authority to determine the compensation for and to terminate the services of the independent compensation consultant. The Compensation Committee has reviewed the independence of the independent compensation consultant pursuant to applicable independence rules and determined that its engagement does not raise any conflicts of interest.

Role of the CEO and the Board of Directors in Determining Compensation

The CEO personally reviews and reports to the Compensation Committee on the performance of select senior executives (including all of the Named Executive Officers other than himself) and provides specific compensation recommendations to the Compensation Committee. The Compensation Committee considers this information in making compensation decisions for these executives, but the Compensation Committee does not delegate its decision-making authority to the CEO. The CEO also provides a self-evaluation to the Compensation Committee. The CEO does not, however, present a recommendation for his own compensation. Prior to making any decisions regarding CEO compensation, the Compensation Committee consults with the non-management Directors and receives input from its independent compensation consultant. After discussing proposed compensation decisions for the CEO with the non-management Directors, the Compensation Committee determines the CEO’s compensation. The CEO is not present when his performance or compensation is evaluated and determined, unless invited by the Compensation Committee.

Compensation Committee Review of Tally Sheets

In setting executive officer compensation, the Compensation Committee reviews tally sheets prepared for each executive officer. The tally sheets provide information that is in addition to the information shown in the 2016 Summary Compensation Table. The tally sheets show not only current

38        Aetna Inc.

COMPENSATION DISCUSSION AND ANALYSIS

year compensation, but also historical equity gains and the in-the-money value of outstanding equity awards (vested and unvested). The tally sheets also show amounts that would be paid under various termination of employment scenarios. While compensation decisions are based on competitive market pay data and individual performance, the Compensation Committee uses the tally sheets as a reference point and as a basis for comparing program participation across the executive group. During 2016, the information in the tally sheets was consistent with the Compensation Committee’s expectations and, therefore, the tally sheets did not have a specific effect on individual compensation decisions.

Compensation Committee Review of Risk

Annually, as part of its compensation review process, the Compensation Committee requests the Company’s chief enterprise risk officer to oversee a review of the Company’s compensation policies for executives and other employees to determine whether those programs create risks that, individually or in the aggregate, are reasonably likely to have a material adverse effect on the Company. As part of this risk review process in 2016, the chief enterprise risk officer, assisted by human resources personnel, inventoried Company compensation programs and established a financial framework, consistent with other enterprise risk management protocols, to identify compensation policies or practices that could have a material adverse effect on the Company. This review included the structure and material features of each program, the behaviors the programs are intended to reward, as well as program features or Company policies that operate to mitigate risk. After conducting the review and assessing potential risks, the Company determined, and the Compensation Committee concurred, that the design of each incentive program contains sufficient design features, controls, limits and/or financial requirements so that the program does not create risks that are reasonably likely to have a material adverse effect on the Company.

Although a significant portion of the Company’s executive compensation is performance-based, we do not believe that our programs encourage excessive or unnecessary risk-taking. Overall, our compensation mix, including the use of equity and other long-term incentives, is generally consistent with competitive market practice. While risk is a necessary part of growing a business, our executive compensation program attempts to mitigate risk and align the Company’s compensation policies with the long-term interests of the Company. The Company does so by utilizing performance goals that are directly aligned with the Company’s strategic plan, balancing annual and longer-term incentives, using multiple performance measures (including financial and non-financial measures) and applying program caps. Other risk mitigation features include the Company’s executive stock ownership requirements and the Company’s “claw back” policy both of which are described below.

Executive Stock Ownership Requirements

The CEO and other senior executives are subject to minimum stock ownership requirements. The ownership requirements are based on the executive’s pay opportunity and position within the Company. The ownership levels (which include shares owned and vested stock units but not SARs, stock options or unvested PSUs) are as follows:

Stock Ownership as a Multiple of Base Salary

Position	Multiple of Salary
Chief Executive Officer	5x
President	4x
Other Named Executive Officers	3x
Other Executives	.5x to 3x

Executive officers who do not meet their individual ownership requirement at the time the equity vests or is exercised are required to retain 50% of the after-tax equity payout in shares of Common Stock until the executive officer’s termination of employment with the Company. All NEOs are in compliance with the Company’s stock ownership and/or retention policy.

Policy on Hedging or Pledging Company Stock

The Company’s Code of Conduct prohibits all employees (including executives) and Directors from engaging in hedging strategies using puts, calls or other types of derivative securities based upon the value of our Common Stock. No Directors or Named Executive Officers entered into a pledge of Common Stock in 2016.

Company Claw Back/Recoupment Policy

Under the Company’s recoupment policy, if the Board determines that a senior executive of the Company has engaged in fraud or intentional misconduct that has caused a material restatement of the Company’s financial statements, the Board will review the performance-based compensation earned by that senior executive on the basis of the Company’s performance during the periods materially affected by the restatement. If, in the Board’s view, the performance-based compensation would have been lower if it had been based on the restated results, the Board may seek to recoup the portion of the performance-based compensation that would not have been awarded to that senior executive. This policy applies to the Company’s executive officers as well as the Chief Accounting Officer and Head of Internal Audit. In addition, equity awards issued to employees include a provision that allows the Company to recoup gains if the employee violates covenants that prohibit terminated employees from soliciting our customers and employees, disclosing confidential information and providing services to certain competitors of the Company.

COMPENSATION DISCUSSION AND ANALYSIS

Internal Revenue Code Section 162(m)

Prior to 2013, Section 162(m) of the Code limited the tax deductibility of compensation in excess of $1 million paid to certain executive officers, unless the payments were made under plans that satisfy the technical requirements of the Code. It had been the Company’s policy to maximize the tax-deductibility of payments as “performance-based compensation” under Section 162(m) to the extent practicable. As part of the federal health care reform legislation enacted in 2010, Section 162(m) was revised with respect to compensation paid by health insurance companies, including the Company. Starting in 2013, an annual deduction limit of $500,000 per person applies to the compensation we pay to any of our employees and certain service providers. The tax deduction limitation applies whether or not the compensation is performance-based or is provided pursuant to a shareholder-approved plan. As a result, the Company has suspended the application of the technical requirements needed to qualify compensation as performance-based under Section 162(m), although our annual bonus and other incentive programs continue to be performance-based.

VI. Compensation Comparison Group Companies

A consolidated Compensation Comparison Group was developed in 2016, combining our former health care and cross-industry comparison groups. Anticipated healthcare industry consolidation coupled with our expanding business footprint created the need to consolidate our former comparison groups into one group, the Compensation Comparison Group. The companies in the Compensation Comparison Group are listed below. The companies were selected from the FORTUNE 200 and are companies that we compete against for talent and capital, while maintaining diverse industry representation. The selected companies represent companies with revenues ranging from .5 to 2x our projected 2016 revenue. The pay information for the group was developed using market pay survey data purchased from third-party compensation vendors.

EXECUTIVE COMPENSATION

The 2016 Summary Compensation Table summarizes the total compensation paid or earned for the fiscal year ended December 31, 2016 and applicable comparative data for 2015 and 2014 by our Chairman and Chief Executive Officer, any person who served as our Chief Financial Officer during 2016 and our three other most highly paid executive officers (collectively, the “NEOs” or “Named Executive Officers”). When setting compensation for each of the NEOs, the Compensation Committee reviews tally sheets which show the executive’s current compensation, including equity and non-equity based compensation.

The cash ABP award amounts for 2016 are disclosed in the 2016 Summary Compensation Table as “Non-Equity Incentive Plan Compensation” and are not categorized as a “Bonus” payment under SEC rules. The amounts listed under “Non-Equity Incentive Plan Compensation” were approved by the Compensation Committee in February 2017. The amount listed under “Bonus” was approved by the Compensation Committee and paid to Mr. Sabatino in recognition of his career move. Please refer to the 2016 Grants of Plan-Based Awards table and related footnotes beginning on page 44 for information about the number of RSUs, PSUs, and SARs, as applicable, awarded to each of the NEOs in the fiscal year ended December 31, 2016.

The Company has entered into employment arrangements with certain of the NEOs. Refer to “Agreements with Named Executive Officers” beginning on page 56 for a discussion of those employment arrangements.

2016 Pension Benefits

The following table sets forth information concerning the present value of the Named Executive Officers’ respective accumulated benefits under the Pension Plan and Supplemental Pension Plan. The present value shown below was determined for each participant based on their accrued benefit as of December 31, 2016, and the discount rates that Aetna used for its 2016 year-end pension disclosures and assumes continued employment to age 65 for Mr. Bertolini. Pursuant to SEC rules, the valuations shown below do not take into account any assumed future pay increases. Messrs. Guertin, Loveman and Sabatino and Ms. Lynch are not eligible to participate in the Pension Plan because they joined the Company after the Pension Plan was frozen on December 31, 2010. Messrs. Guertin, Loveman and Sabatino and Ms. Lynch are not eligible to participate in the Supplemental Pension Plan. No NEO received any payment from the Pension Plan or the Supplemental Pension Plan during 2016.

In addition, the Supplemental Pension Plan may continue to be used to credit benefits for special pension agreements. Refer to “Pension Plan Narrative” below.
(2)	Refer to pages 122-128 of Aetna’s 2016 Annual Report on Form 10-K for a discussion of the valuation methods used to calculate the amounts in this column. In calculating the present value of the accumulated benefit under the Pension Plan and the Supplemental Pension Plan, the following economic assumptions were used:

	Pension Plan	Supplemental Pension Plan
Discount Rate	4.23%	3.97%
Future Cash Balance Interest Rate	2.50%	2.50%
5-Year Average Cost of Living Adjustment	2.30%	2.30%

Pension Plan Narrative

Prior to January 1, 2011, the Company provided the Pension Plan, a non-contributory, defined benefit pension plan, for most of its employees. In 1999, the Pension Plan was amended to convert the Pension Plan’s final average pay benefit formula to a cash balance design. Under this design, the pension benefit is expressed as a cash balance account. Each year through December 31, 2010, a participant’s cash balance account was credited with (i) a pension credit based on the participant’s age, years of service and eligible pay for that year, and (ii) an interest credit based on the participant’s account balance as of the beginning of the year and an interest rate that equals the average 30-year U.S. Treasury bond rate for October of the prior calendar year. For 2016, the interest rate was 2.89%. For purposes of the Pension Plan, eligible pay was generally base pay and certain other forms of cash compensation, including annual performance bonuses, but excluding long-term incentive compensation and proceeds from stock option and SAR exercises and other equity grants. The maximum eligible pay under the Pension Plan was set annually by the Internal Revenue Service.

48        Aetna Inc.

EXECUTIVE COMPENSATION

Effective December 31, 2010, the Pension Plan was frozen. No further pension service credits will be earned after that date. However, participants’ cash balance accounts will continue to be credited with the interest credit. Under the Pension Plan, benefits are paid over the lifetime of the employee (or the joint lives of the employee and his or her beneficiary) except that the employee may elect to take up to 100% of his or her benefits in a lump sum payment following termination of employment.

The Code limits the maximum annual benefit that may be accrued under and paid from a tax-qualified plan such as the Pension Plan. As a result, Aetna established the Supplemental Pension Plan, an unfunded, non-tax qualified supplemental pension plan that provides benefits (included in the amounts listed in the 2016 Pension Benefits table above on page 48), that exceed the Code limit. Supplemental Pension Plan benefits are paid out in five equal annual installments commencing six months following termination of employment. As of January 1, 2007, the Supplemental Pension Plan is no longer used to accrue benefits that exceed the Code limits, but interest continues to accrue on the outstanding cash balance accruals.

2016 Nonqualified Deferred Compensation

Deferred Compensation Narrative

The “Salary” and “Non-Equity Incentive Plan Compensation” columns in the 2016 Summary Compensation Table include cash compensation that was deferred by the Named Executive Officers during 2016. The Company permits executives to defer up to 40% of eligible pay (which includes base salary and annual bonus) into the 401(k) Plan (subject to deferral limits established by the Code — in 2016, $18,000 ($24,000 for individuals age 50 and older)). The 401(k) Plan, which is available to all eligible employees of the Company, is a funded arrangement that provides twenty investment options, as well as a self-directed brokerage option. Aetna matches 100% of the amount deferred by employees, including the NEOs, under the 401(k) Plan up to 6% of eligible pay. Under the 401(k) Plan, benefits are paid to the employee (including NEOs) after termination of employment on the date selected by the employee.

Aetna established the Supplemental 401(k) Plan to provide the deferral that would have been credited to the 401(k) Plan but for limits imposed by the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and the Code. The Supplemental 401(k) Plan allows eligible employees, including the NEOs, to defer up to an additional 10% of base salary. Aetna does not match employees’ contributions to the Supplemental 401(k) Plan. The Supplemental 401(k) Plan is an unfunded plan that credits interest at a fixed rate pursuant to a formula equal to the rate of interest paid from time to time under the fixed interest rate fund option of the 401(k) Plan. The 401(k) Plan interest rate is set quarterly to better align the credited rates with the underlying fixed income investment earning rates achieved in the fund. In 2016, this fixed interest rate was 2.05% from January to March, 2.10% from April to June, 2.10% from July to September and 2.15% from October to December. In 2017, this fixed interest rate is 2.00% from January to March. Under the Supplemental 401(k) Plan, benefits are paid to the executive on the later of six months or January 1 following termination of employment.

The Company also permits executives to defer up to 100% of their annual bonus. The deferral arrangement for annual bonuses is also unfunded and permits investment in either an interest account or a stock unit account. The interest account credits interest at the same rate as the Supplemental 401(k) Plan. The stock unit account tracks the value of the Common Stock. The stock unit account earns dividend equivalents, paid in the manner of the individual’s selection. This arrangement pays out on a date selected by the executive at the time of deferral. The Compensation Committee may also require or permit other compensation to be deferred.

Potential Post-Employment Payments

Regardless of the manner in which a Named Executive Officer’s employment terminates, he or she is entitled to receive certain amounts earned during his or her term of employment, including the following: (a) accrued salary; (b) deferred compensation amounts; (c) amounts accrued and vested through the 401(k) Plan and Supplemental 401(k) Plan; and (d) amounts accrued and vested through the Pension Plan and Supplemental Pension Plan. In addition, except as provided in the tables below, each NEO is eligible to receive vested equity awards upon a termination of employment for any reason (other than for cause). Equity awards (other than PSUs) continue to vest for all employees during any period of severance or salary continuation. The actual amounts paid to any NEO can only be determined at the time of the executive’s separation from the Company. Section 409A of the Code may require the Company to delay the payment of certain payments for six months following termination of employment. Refer to the 2016 Nonqualified Deferred Compensation table and “Deferred Compensation Narrative” beginning on page 49 for a discussion of the deferred compensation plan, 401(k) Plan and Supplemental 401(k) Plan. Refer to the 2016 Pension Benefits table and “Pension Plan Narrative” beginning on page 48 for a discussion of the Pension Plan and Supplemental Pension Plan. Refer to the Outstanding Equity Awards at 2016 Fiscal Year-End table beginning on page 46 for a discussion of outstanding equity awards at December 31, 2016.

Unless otherwise indicated, each of the tables for the NEOs below assumes a termination of employment (or change in control and termination of employment without Cause and/or for Good Reason, as defined below, as applicable) as of December 31, 2016, and assumes a Common Stock price of $124.01 per share (the closing price of the Common Stock on December 31, 2016) and, for illustrative purposes, an immediate sale of equity awards upon termination of employment at $124.01 per share. Change in control severance benefits (base salary and bonus payments, if any) to each NEO are paid pursuant to a “double-trigger,” which means that to receive such benefits employment must terminate both: (1) as a result of a qualifying termination of employment, and (2) after a change in control as detailed in the agreements described below and under “Agreements with Named Executive Officers” beginning on page 56. Unless otherwise indicated, the amounts set forth in the tables that follow under “PSUs” were calculated based upon the Compensation Committee’s determination that the Company achieved maximum performance of 200% of target for PSUs granted in 2014. For “Termination after Change-in-Control,” PSUs granted in 2014 are assumed to vest at actual performance. The PSUs granted in 2015 and 2016 are assumed to vest at target performance both in the case of a change in control and in the case of certain qualified terminations (pro-rated for the number of months employed during the vesting period). The performance metric for the 2015 PSUs is cumulative adjusted operating EPS and cumulative revenue from January 1, 2015 through December 31, 2017. If performance were calculated at December 31, 2016, these PSUs would perform below target. Actual performance of and payouts of the 2015 PSUs may change significantly by December 31, 2017. The performance metric for the 2016 PSUs is a three-year compound annual growth rate of adjusted operating earnings per share target from January 1, 2016 through December 31, 2018. If performance were calculated at December 31, 2016, these PSUs would perform below target. Actual performance of and payouts of the 2016 PSUs may change significantly by December 31, 2018. Refer to footnotes 3 and 5 to the 2016 Summary Compensation Table for information on the grant date fair value of the PSUs granted in 2016 at maximum performance.

The NEOs’ equity award agreements define “Change in Control” as the occurrence of any of the following events: (a) a person or group acquires 20% or more of the combined voting power of the Company’s then outstanding securities; (b) during any period of 24 consecutive months, the individuals who, at the beginning of such period, constitute the Board cease for any reason (other than death) to constitute a majority of the Board, unless any such new Director was elected, recommended or approved by at least two-thirds of the other Directors then in office; or (c) a transaction requiring shareholder approval for the acquisition of the Company by an entity other than the Company or a subsidiary of the Company through the purchase of assets, or by merger, or otherwise.

As of December 31, 2016, Mr. Bertolini was considered retirement eligible for purposes of equity vesting. Under her employment agreement, Ms. Lynch is considered retirement eligible for purposes of the vesting provisions of her equity awards upon certain terminations of her employment.

Mr. Bertolini’s employment agreement defines “Good Reason” as the occurrence of one or more of the following without Mr. Bertolini’s consent: (a) a reduction by the Company of base salary or target cash bonus opportunity (except in the event of a ratable reduction prior to a change in control affecting all senior officers of the Company); (b) within 24 months following a change of control, a reduction in the level of the long-term incentive plan opportunity from that afforded him immediately prior to the change in control; (c) any failure of a successor of the Company to assume and agree to perform the Company’s entire obligations under the employment agreement; (d) reporting to any person other than the Company’s Board of Directors; (e) any action or inaction by the Company that constitutes a material breach of the employment agreement; (f) removal of Mr. Bertolini as President, Chief Executive Officer or Director; or (g) the appointment of any person to the position of executive Chairman.

EXECUTIVE COMPENSATION

Agreements with Named Executive Officers

Aetna and Mr. Bertolini amended his amended and restated employment agreement effective August 4, 2013. The amendment extended the remaining term of the agreement to December 31, 2016, with automatic one-year extensions thereafter. Under his agreement, Mr. Bertolini is entitled to an annual salary of $1 million, and a full year target bonus opportunity of at least 300% of his base salary. Not greater than 40% of his bonus opportunity is payable in cash, and the noncash amount is payable through equity-based compensation vehicles. Effective in April 2016, Mr. Bertolini’s base salary was increased to $1,200,000. If Aetna terminates Mr. Bertolini’s employment other than for “Cause” (as defined in the agreement), death or disability, or Mr. Bertolini terminates his employment for “Good Reason” (as defined in the agreement), he will be entitled to 24 months of cash compensation (calculated as annual base salary and target cash bonus opportunity) plus a pro rata portion of his target cash bonus opportunity for the year of termination. Under certain circumstances the amounts payable to Mr. Bertolini following a change in control will be reduced to an amount that maximizes the net after tax amount retained by him to the extent permitted under Section 409A of the Code. Under the non-competition agreement entered into in July 2007 between Aetna and Mr. Bertolini, Mr. Bertolini agreed not to compete against the Company for a period of one year following termination of his employment. The applicable table above under “Potential Post-Employment Payments” reflects the provisions of Mr. Bertolini’s agreements with the Company.

Under his letter agreement with the Company, Mr. Guertin was hired with an annual base salary of $500,000 and a full year target bonus opportunity of 80% of his base salary. Mr. Guertin’s base salary was increased to $700,000 and his full year target bonus opportunity was increased to 100% of his base salary upon his promotion to Chief Financial Officer in 2013. Effective March 9, 2015, Mr. Guertin’s full year target bonus opportunity was increased to 110% of his base salary (pro-rated for performance year 2015), and effective April 6, 2015 and September 24, 2015, Mr. Guertin’s base salary was increased to $750,000 and $800,000, respectively. If Mr. Guertin’s employment is involuntarily terminated under circumstances that would call for severance pay benefits and/or salary continuation benefits under the Company’s severance and salary continuation plan then in effect, Mr. Guertin will receive payment for 52 weeks of salary continuation in lieu of amounts payable under such severance and salary continuation benefits plan. Under his agreements with Aetna, Mr. Guertin has agreed not to compete against the Company for a period of one year following termination of his employment. The applicable table above under “Potential Post-Employment Payments” reflects the provisions of Mr. Guertin’s agreements with the Company.

Under his letter agreement with the Company, Mr. Loveman was hired with an annual base salary of $800,000 and a full year target bonus opportunity of 110% of his base salary (pro-rated for 2015). Mr. Loveman’s salary will not be reduced without his consent other than in connection with a ratable reduction affecting all senior officers of the Company. In addition, management has agreed to recommend to the Compensation Committee that future PSU grants to Mr. Loveman have associated performance measures that will be specific to the businesses under his direction and have a maximum unit multiplier of 300% or higher. If Mr. Loveman’s employment is involuntarily terminated other than for “Cause” (as defined in Mr. Loveman’s agreement) or Mr. Loveman resigns because he is required to report to an officer other than the Company’s chief executive officer, Mr. Loveman will receive payment for 52 weeks of salary in lieu of amounts payable under any Company severance and salary continuation benefits plan upon delivery of a release of employment-related claims against Aetna. The agreement also permits Mr. Loveman to remain the non-executive Chairman of Caesars Entertainment Corporation until his anticipated departure from that role in May 2016. Under his agreements with Aetna, Mr. Loveman has agreed not to compete against the Company for a period of one year following termination of his employment. The applicable table above under “Potential Post-Employment Payments” reflects the provisions of Mr. Loveman’s agreements with the Company.

On December 10, 2014, Aetna and Ms. Lynch entered into an employment agreement following her appointment as President of Aetna effective January 1, 2015. Under the agreement, commencing January 1, 2015, Ms. Lynch’s base salary is $900,000, and her annual bonus opportunity at target performance is at least 120% of her base salary. Effective in April 2016, Ms. Lynch’s base salary was increased to $931,500. If Ms. Lynch’s employment is involuntarily terminated by Aetna other than for “Cause” (as defined in the agreement), or if Ms. Lynch terminates her employment for Good Reason (as defined in the agreement) (each, a “Qualifying Event”), she will receive, in addition to previously earned compensation: (a) cash compensation in periodic payments over twenty-four (24) months of two times the sum of her highest base salary in effect during the six months prior to termination of her employment and her annual bonus opportunity for the year of termination of employment (which is defined in the agreement as at least 120% of base salary then in effect) and (b) a pro rata annual bonus at target performance for the year of termination of

In addition, Ms. Lynch will be treated as retirement eligible for purposes of the vesting and exercise terms of all her outstanding equity awards. These payments are conditioned upon Ms. Lynch delivering a release of employment-related claims to Aetna. The initial employment term under the agreement was through December 31, 2015. The employment term automatically renewed on December 31, 2015 and will automatically renew on December 31 of each subsequent year, unless Aetna or Ms. Lynch provides notice of its or her intention not to extend the employment term. If Ms. Lynch terminates her employment at the end of the employment term upon Aetna’s notice of non-renewal, she will receive the benefits described above for a termination of employment due to a Qualifying Event. Either Aetna or Ms. Lynch can terminate the agreement at any time. Under her agreements with Aetna, Ms. Lynch has agreed not to compete against the Company for a period of one year following termination of her employment. The applicable table above under “Potential Post-Employment Payments” reflects the provisions of Ms. Lynch’s agreements with the Company.

Under his letter agreement with the Company, Mr. Sabatino was hired with an annual base salary of $750,000 and a full year target bonus opportunity of 100% of his base salary, which will not be pro-rated for the 2016 performance year. In addition, a one-time payment of $600,000 (less applicable withholding and taxes) was made in recognition of Mr. Sabatino’s career move.

If he voluntarily terminates his employment or is terminated for Cause after 12 months, but before 18 months after his start date, Mr. Sabatino will be responsible for repaying 50% of his one-time payment. Mr. Sabatino will receive payment for 52 weeks of salary in lieu of amounts payable under any Company severance and salary continuation benefits plan upon delivery of a release of employment-related claims against Aetna.

Job Elimination Benefits Plan

Aetna administers a Job Elimination Benefits Plan under which eligible employees, including Aetna’s executive officers, terminated by Aetna due to re-engineering, reorganization or staff reduction efforts may receive a maximum of 52 weeks of continuing salary depending on years of service and pay level. Under certain circumstances, determined on a case-by-case basis, additional severance pay benefits may be granted for the purpose of inducing employment of senior officers or rewarding past service. The tables above under “Potential Post-Employment Payments” reflect any benefits payable under the Job Elimination Benefits Plan to the extent NEOs are not entitled to severance under individual agreements. Certain health and other employee benefits continue for part of the severance period.

The Board has approved provisions for certain benefits of eligible Company employees upon a change in control of Aetna (as defined). The provisions provide that the Job Elimination Benefits Plan shall provide an enhanced benefit and shall become noncancelable for a period of two years following a change in control. Upon a change in control, PSUs granted on or after January 1, 2010 that have not yet vested will become vested and immediately exercisable, and bonuses payable under the Annual Incentive Plan will become payable based on the target award for participants. Upon a change in control, stock options, SARs and RSUs granted on or after January 1, 2010 vest upon a termination of employment by the Company other than for cause within 24 months after the change in control. Provision also has been made to maintain the aggregate value of specified benefits for one year following a change in control.
