KEY EXECUTIVE COMPENSATION POLICIES AND PRACTICES


Stockholder Aligned Executive Compensation Program	•	Our senior executives have a high percentage of variable (“at risk”) pay

	•	Our Compensation Committee has an independent compensation consultant
Compensation Recovery Policies	•	We have clawback policies for senior executive annual bonus awards and for equity-based compensation
Severance and Change in Control	•	Severance protections for our senior executives, including our CEO, are at a 1x multiple of base salary and bonus, with a pro-rata bonus for the year of termination. Further, we are required as a matter of policy to obtain stockholder approval for severance agreements with certain senior executives if they provide for cash severance that exceeds 2.99 times the executive’s base salary and three-year average annual bonus award
	•	We provide “double-trigger” vesting of equity-based awards and payment of severance benefits following a change in control of the Company
	•	We do not provide golden parachute excise tax gross-ups in connection with a change in control of the Company
Say on Pay	•	We hold an advisory vote on named executive officer compensation each year

PROXY SUMMARY (Continued)

HIGHLIGHTS OF OUR 2020 PERFORMANCE AND COMPENSATION


Supporting Our Colleagues Through COVID-19		• As COVID-19 spread around the world, we prioritized the health and well-being of our colleagues. • Early in the crisis, we were one of the first companies to commit to protect jobs during the thick of the pandemic. • We implemented 2020 salary increases as planned with no pandemic-related pay cuts. • We accrued broad-based 2020 bonus pools in line or above 2019 levels, commensurate with performance. • We expanded our employee assistance program to cover over 80% of colleagues worldwide, extended telemedicine to 26 countries and established a $5 million fund to support colleagues experiencing personal financial hardship stemming from the pandemic. • We achieved record colleague engagement scores, with increases in all of our businesses and across all key engagement items.
Leading the Change for Racial and Social Justice		• When communities around the world joined in solidarity last year to confront racial and social injustice, we recognized the gaps in hiring diversity and real inclusion at Marsh McLennan—and introduced our “Leading the Change” program to address them with urgency. • We created a Race Advisory Council to advise the Executive Committee so diverse perspectives are considered in decision-making, especially decisions that affect our colleagues. • We committed to hire more Black colleagues at every level and launched new initiatives to support career development, connection and empowerment for our Black colleagues. • We also committed $5 million over the next three years to support nonprofit organizations that advocate for equity in the Black community and doubled the Company’s match for colleague donations to organizations that advocate for social justice.
Positioning Our Business For the Future		• We accelerated collaboration and cross-business activity and continued to move toward a more integrated enterprise. • We rapidly pivoted our business in response to the COVID-19 pandemic to support clients and develop new solutions, including Oliver Wyman’s Pandemic Navigator, a leading disease-progression model; a supplemental insurance product for individuals affected by COVID-19; public-private partnerships for pandemic risk insurance; and return-to-office and “new normal” strategies. • We successfully completed the integration of Jardine Lloyd Thompson plc (“JLT”), the largest acquisition in the Company’s 150-year history that is providing clients with enhanced talent, capabilities and geographic footprint. • We continued to build out Marsh & McLennan Agency through acquisitions, closing on eight transactions representing approximately $235 million of annualized revenue, including Assurance Holdings.

PROXY SUMMARY (Continued)

HIGHLIGHTS OF OUR 2020 PERFORMANCE AND COMPENSATION


Financial Objectives		• In 2020, Marsh McLennan delivered strong performance as we successfully navigated the global health and economic crises to execute on our long-term financial and strategic objectives. • GAAP EPS increased 16%, and we delivered 7% growth in adjusted EPS* despite a challenging business environment due to COVID-19. • We generated $17 billion of revenue, an increase of 3% compared with 2019. We achieved 1% growth in underlying revenue. • Our *overall adjusted margin increased 120 basis points, our 13^th consecutive year of margin improvement. • With JLT cost savings well ahead of schedule, we are on track to deliver more than $425 million of run-rate savings by the end of 2021** and exceed our original target of $250 million. * Please see Exhibit A for a reconciliation of our non-GAAP financial measures to GAAP financial measures and related disclosures.
Capital Management		• We increased our quarterly dividend from $0.455 to $0.465 per share beginning in the third quarter of 2020, resulting in an annual dividend increase of 5.7%, from $1.74 to $1.84. Our dividend has increased every year since 2010. • We remained on track with our deleveraging plans through earnings growth and a firm-wide emphasis on expense discipline.
Stock Performance		• Our 2020 total stockholder return (“TSR”) was 6.8%. • Our five-year annualized TSR of 18.3% outperformed the S&P 500^® index TSR by 3.1 percentage points.

PROXY SUMMARY (Continued)

HIGHLIGHTS OF OUR 2020 PERFORMANCE AND COMPENSATION

Executive Compensation

LOGO

• In February 2020, prior to the onset of the COVID-19 pandemic, the Compensation Committee set rigorous performance targets for our annual bonus plan and long-term incentive (“LTI”) plan and did not subsequently reset or adjust targets despite the impact of COVID-19.

• In February 2021, the Compensation Committee assessed management’s performance against the original 2020 objectives and resiliency in responding to the pandemic. The Compensation Committee determined bonuses that were above-target yet below last year’s levels for all of our named executive officers, except Ms. Ferland. As Ms. Ferland successfully completed her second year leading the Mercer business, the Compensation Committee determined her annual bonus above last year’s level and also increased her annual LTI award to recognize her performance and appropriately position her compensation compared to internal peers.

• We achieved three-year annualized adjusted EPS growth of 8.4% for our 2018 performance stock unit awards. This was above our 8% target for the award and resulted in a payout at 110% of target. Despite the impact of the pandemic on our financial performance, the Compensation Committee did not subsequently reset or adjust the 8% target for three-year annualized adjusted EPS growth applicable to the 2018, 2019 or 2020 performance stock unit awards.

• Starting with the 2020 LTI awards, we made two key changes to the design of our annual LTI design in order to more closely align executive rewards with stockholder interests. We increased the proportion of performance stock award units to 50% for our senior executives and added a relative TSR modifier based on the Company’s three-year TSR versus S&P 500^®companies. In making these decisions, the Compensation Committee took into account stockholder views.

CORPORATE GOVERNANCE

We describe key features of the Company’s corporate governance environment below and in the next section of this proxy statement, captioned “Board of Directors and Committees.” Our key corporate governance materials are available online at mmc.com/about/corporate-governance.html.

OVERVIEW

Our Board of Directors currently has thirteen (13) members, including H. Edward Hanway, our independent chairman, and Daniel S. Glaser, our President and Chief Executive Officer. Mr. Glaser is the only member of management who serves as a director. As described in more detail under “Board of Directors and Committees,” our Board maintains an Audit Committee, a Compensation Committee, a Directors and Governance Committee, a Finance Committee, an ESG Committee and an Executive Committee.

CORPORATE GOVERNANCE PRACTICES

The Company is committed to best practices in corporate governance. Highlights of our corporate governance practices are described below.

Board Structure

•

Board Independence. All of the Company’s directors are independent, with the exception of our CEO, who is the only member of management serving on the Board.

•

Independent Chairman. The Company maintains separate roles of chief executive officer and chairman of the Board as a matter of policy. An independent director acts as chairman of the Board.

•

Offer to Resign upon Change in Circumstances. Pursuant to our Governance Guidelines, any director undergoing a significant change in professional circumstances must offer to resign from the Board.

Election of Directors

•

Annual Election of Directors. The Company’s charter provides for the annual election of directors.

•

Majority Voting in Director Elections. The Company’s bylaws provide that, in uncontested elections, director candidates must be elected by a majority of the votes cast. Each director candidate has previously tendered an irrevocable resignation that will be effective upon his or her failure to receive the requisite votes and the Board’s acceptance of such resignation.

Proxy Access

•

Proxy Access. The Company’s bylaws permit a stockholder, or a group of up to 20 stockholders, owning 3% or more of the Company’s outstanding common stock continuously for at least three years to nominate and include in the Company’s proxy materials directors constituting up to the greater of two or 20% of board seats, if the stockholder(s) and the nominee(s) meet the requirements in our bylaws.

Right of Stockholders to call Special Meetings

•

Stockholder Right to Call Special Meetings. The Company’s bylaws allow holders of record of at least 20% of the voting power of the Company’s outstanding common stock to call a special meeting.

Stockholder Rights Plan

•

No Poison Pill. The Company does not have a stockholder rights plan in place.

Compensation Practices

•

Compensation Structure for Independent Directors. The Company’s director compensation structure is transparent to investors and does not provide for meeting fees or retainers for non-chair committee membership.

•

Cap on Executive Severance Payments. The Company is required as a matter of policy to obtain stockholder approval for severance agreements with certain senior executives if they provide for cash severance that exceeds 2.99 times the executive’s base salary and three-year average annual bonus award. Severance protections for our senior executives, including our CEO, are at a 1x multiple of base salary and bonus, as described in “Severance Arrangements” on pages 46-47.


		Marsh & McLennan Companies, Inc. Notice of Annual Meeting and 2021 Proxy Statement			1

CORPORATE GOVERNANCE (Continued)

•

“Double-Trigger” Condition for Vesting of Equity-Based Awards following a Change in Control. Our equity-based awards contain a “double-trigger” vesting provision, which requires both a change in control of the Company and a specified termination of employment in order for vesting to be accelerated.

•

“Clawback” Policies. The Company may as a matter of policy recoup (or “claw back”) certain executive bonuses in the event of misconduct leading to a financial restatement. Also, our 2020 Incentive and Stock Award Plan allows the Company to “claw back” outstanding or already settled equity-based awards.

Equity Ownership and Holding Requirements

•

Senior Executive Equity Ownership and Holding Requirements. The Company requires senior executives to hold shares or stock units of our common stock with a value equal to a multiple of base salary. The multiple for our Chief Executive Officer is six, and the multiple for our other senior executives is three. Senior executives are required to hold shares of the Company’s common stock acquired in connection with equity-based awards until they reach their ownership multiple and may not sell any shares of the Company’s common stock unless they maintain their ownership multiple.

•

Director Equity Ownership and Holding Requirements. Directors are required to acquire over time, and thereafter hold (directly or indirectly), shares or stock units of our common stock with a value equal to at least five times the Board’s basic annual retainer (currently, $600,000). Directors may not sell shares of the Company’s common stock until this ownership threshold is attained.

GUIDELINES FOR CORPORATE GOVERNANCE

The Company and the Board of Directors formally express many of our governance policies through our Guidelines for Corporate Governance (our “Governance Guidelines”). The Governance Guidelines are posted on our website at mmc.com/about/corporate-governance.html.

The Governance Guidelines summarize certain policies and practices designed to assist the Board in fulfilling its fiduciary obligations to the Company’s stockholders, including the following (parenthetical references are to the relevant section of the Governance Guidelines):

STOCKHOLDER ENGAGEMENT

In 2011, we expanded the breadth and consistency of our stockholder engagement. In each of the past five years, we have engaged with institutional stockholders holding approximately 36% to 45% of our outstanding common stock. In 2020, we held meaningful discussions with stockholders covering corporate governance, executive compensation, Board and workforce diversity, climate and other environmental and social topics. Feedback received during the stockholder engagement process is shared with senior executives, the Board and its committees and is considered in making decisions. For example, we incorporated stockholder feedback in making changes to our executive compensation program in 2020 and determining many of the topics addressed in our ESG Report, including our response to COVID-19, our climate commitments and our enhanced disclosure around workforce diversity. We are committed to ongoing engagement with our stockholders and intend to continue these outreach efforts.

RISK OVERSIGHT

It is the responsibility of the Company’s senior management to assess and manage our exposure to risk and to bring to the Board’s attention the most material risks facing the Company. The Board oversees risk management directly and through its committees.

Annually, the Board reviews management’s assessment of the Company’s key enterprise risks. Senior management then briefs the Board on its strategy with respect to each risk and provides a mid-year status update and a report at year-end. The Board receives updates from management on specific risks throughout the year, including on human capital management and cybersecurity.

The Audit Committee regularly reviews the Company’s policies and practices with respect to risk assessment and risk management, including cybersecurity risk. The Directors and Governance Committee considers risks related to CEO succession planning, and the Compensation Committee considers risks relating to the design of executive compensation programs and arrangements. See the discussion under “Committees” on page 14 for additional information about the Board’s committees.

ENVIRONMENTAL, SOCIAL AND GOVERNANCE (ESG) OVERSIGHT AND ACTIVITIES

The Board has formally focused on key aspects of the Company’s environmental, social and governance (ESG) initiatives since 2008, when it created a Board committee with oversight of these issues. In addition, the Company has a management committee with colleagues across our four global businesses and corporate departments to coordinate and communicate on the Company’s ESG initiatives. Our inaugural ESG Report, Pay Equity Statement, statement on Human Rights and related information is available on our website at mmc.com/about/esg.html. The reports and our website are not deemed part of this proxy statement and are not incorporated by reference.

The Board oversees the Company’s ESG initiatives and strategies primarily through its committees.

ESG Committee. The ESG Committee oversees and supports the Company’s commitment to social, environmental and other public policy initiatives. It is comprised of members who have been selected based upon their tenure, competence and expertise and includes members from each of the Board’s other committees. The ESG Committee receives reports

at least annually on environmental matters from the Company’s Chief Sustainability Officer and on diversity and inclusion and social impact matters from the Company’s Chief People Officer. The ESG Committee maintains contact with the Directors and Governance Committee and the Compensation Committee on matters of mutual interest relating to corporate governance.

Compensation Committee. The Compensation Committee has responsibility to review certain key human resource strategic activities, including those relating to diversity, training and recruitment. The Compensation Committee coordinates with the ESG Committee on diversity initiatives and receives annual reports on diversity and inclusion from the Company’s Chief People Officer.

Directors and Governance Committee. The Directors and Governance Committee takes a leadership role in shaping the Company’s corporate governance principles and practices. It receives regular updates on governance practices and developments from the Company’s General Counsel.

Audit Committee. The Audit Committee has responsibility for the Company’s policies, systems and controls designed to promote ethical behavior and compliance with applicable legal and regulatory requirements. It receives regular updates from the Company’s Chief Compliance Officer.

Following each committee meeting, the respective committee chair reports on the meeting to the full Board. See the discussion under “Committees” on page 14 for additional information about the Board’s committees.

Management ESG Committee. An internal committee with members drawn from across the Company’s senior management helps coordinate the Company’s ESG initiatives. The committee is comprised of colleagues from our four global businesses and corporate departments. Members of the committee include the Company’s Deputy General Counsel, Corporate Secretary & Chief Compliance Officer, secretaries to the Board’s committees, the Company’s Chief Sustainability Officer, as well as other colleagues who support the Company’s ESG initiatives.

CODES OF CONDUCT

Our reputation is fundamental to our business. The Company’s directors, senior executives and colleagues are expected to act ethically at all times. The Company’s codes of conduct and ethics are posted on the Company’s website at mmc.com and copies are available to any stockholder upon request.

The Greater Good

Foundational to who we are is our culture of integrity, reflected in The Greater Good, our code of conduct everywhere we do business in the world. It is aligned around three key pillars: (1) Win With Integrity, (2) You are Never Alone, and (3) Speak Up.

The Greater Good applies to all of our directors, officers and other colleagues and requires the Company’s agents, subcontractors and suppliers to comply with relevant aspects of our compliance policies. Each year, the Company’s directors and senior executives certify their commitment to The Greater Good.

The Greater Good supports colleagues in making decisions in situations where it may not be clear—or easy. Our colleagues are provided with comprehensive training and communication of The Greater Good, including through our digital hub at integrity.mmc.com. In 2020, accompanied by manager-led training and discussions about what it means to live The Greater Good, an updated version of The Greater Good was distributed to colleagues to recertify their commitment to The Greater Good.

Code of Ethics for the CEO and Senior Financial Officers

The Company has also adopted an additional Code of Ethics for the Chief Executive Officer and Senior Financial Officers, which applies to our chief executive officer, chief financial officer and controller. We will disclose any amendments to, or waivers of, the Code of Ethics for the Chief Executive Officer and Senior Financial Officers on our website at mmc.com within four business days.

CEO SUCCESSION PLANNING AND SUCCESSION PLANNING FOR SENIOR EXECUTIVES

The Board believes that planning for CEO succession is one of its most important responsibilities. CEO succession planning is regularly discussed at Board meetings and in executive sessions. In addition, every year our CEO and Chief People Officer review with the Board potential internal candidates, including their qualifications, experience and development. At least annually, independent directors meet with the CEO to discuss potential successor candidates and their qualifications, experience and preparedness. The Board, taking into account the recommendations of the Directors and Governance Committee, approves and maintains a succession plan for the CEO. A confidential procedure is also maintained for the timely and efficient transfer of the CEO’s responsibilities in the event of an emergency or his sudden incapacitation or departure. In addition, our Governance Guidelines provide that, to the extent that a search firm is retained to identify external candidates for CEO, the Board will instruct the search firm to reflect gender, race, ethnic and cultural diversity in the initial pool of candidates.

The Board also believes that planning for succession below the CEO level is a key responsibility. The CEO periodically reviews with the independent directors the performance of senior executives and their qualifications, experience and development. The Compensation Committee has responsibility for reviewing the Company’s executive talent review process for senior executives. Every year, our Chief People Officer and CEO review with the Compensation Committee succession plans for direct reports to the CEO and other key executive positions.

Directors engage with senior executives and others at Board, committee and preparatory meetings as well as an annual meeting of the Board and the MMC Executive Committee. Directors also engage with senior executives and others in less formal settings to allow directors to personally assess potential candidates for CEO and senior executive roles.

DIRECTOR RECRUITMENT, NOMINATION AND SUCCESSION PLANNING

The Board, taking into account the recommendation of the Directors and Governance Committee, is responsible for nominating a slate of director candidates for election at the Company’s annual meeting of stockholders.

CORPORATE GOVERNANCE (Continued)

Director Recruitment

The Board has delegated to the Directors and Governance Committee the authority to identify, consider and recommend to the Board potential new director candidates. An overview of the Board’s director recruitment process is provided below.

OVERVIEW OF DIRECTOR RECRUITMENT PROCESS

Evaluate Board Composition

• The Directors and Governance Committee reviews Board composition at least annually.

• The Committee reviews with the Board periodically the skills and characteristics to be sought in director candidates.

Identify Diverse Pool

of Candidates

• The Directors and Governance Committee and the Board seek to reflect gender, racial and ethnic diversity in the pool of director candidates.

• Candidates may be recommended by search firms engaged by the Committee, other directors and stockholders.

• Our Governance Guidelines provide that, to the extent that a search firm is retained to identify external director candidates, the Board will instruct the search firm to reflect gender, race, ethnic and cultural diversity in the initial pool of candidates.

Assess Potential Candidates

• Potential candidates are evaluated against the “Director Qualifications” on page 10 and the skills and experiences shown in the “Director Skills and Experience” matrix on page 11, as well as for independence and potential conflicts.

• Members of the Directors and Governance Committee and other directors meet with potential candidates.

Recommend Candidates for

Approval

• The Directors and Governance Committee recommends candidates to the Board for approval.

• Stockholders vote on director nominees at the annual meeting of stockholders.

Director Nomination Process

As part of the process for nominating director candidates, the Board evaluates each individual director in the context of the Board as a whole, with the objective of recommending a group that can best support the success of our business and represent stockholder interests. In deciding whether to nominate an incumbent director for re-election, the Board considers many factors, including the criteria described under “Director Qualifications” on page 10 such as gender, racial and ethnic diversity, as well as his or her length of service and performance on the Board.

Director Succession Planning

The Board is committed to effective succession planning. The Directors and Governance Committee has responsibility to review the composition and structure of the Board as a whole, taking into account such factors as the Board’s current mix and diversity of skills, backgrounds and experiences, and to make recommendations to the Board as appropriate. In its review of Board composition, the Directors and Governance Committee considers succession planning in light of factors such as skills needed and upcoming retirements and other potential departures.

DIRECTOR ORIENTATION AND CONTINUING EDUCATION

New directors participate in an orientation program throughout their first year on the Board to familiarize them with the Company’s business, strategy, finances, policies, corporate governance practices and culture. The orientation program includes in-person meetings with the Company’s senior executives and comprehensive background materials including


6		Marsh & McLennan Companies, Inc. Notice of Annual Meeting and 2021 Proxy Statement

CORPORATE GOVERNANCE (Continued)

our code of conduct, The Greater Good. Directors certify their commitment to The Greater Good every year. Additional orientation sessions with key advisors are provided for Audit and Compensation Committee members. Orientation sessions are also tailored upon request to meet directors’ needs and interests.

Directors are also encouraged to participate in continuing education programs. Continuing education programs may be part of regular Board or committee meetings or third-party presentations. Additionally, the Company pays for directors to have access to third-party resources that provide updates on issues and programs relevant to public companies and their directors.

DIRECTOR INDEPENDENCE

The Board has determined that all directors other than Mr. Glaser are independent under the New York Stock Exchange (“NYSE”) listed company rules and the standards set forth in the Governance Guidelines. Therefore, the Board has satisfied the objective, set forth in the Governance Guidelines, that a substantial majority of the Company’s directors be independent of management.

For a director to be considered independent, the Board must affirmatively determine that the director has no direct or indirect material relationship with the Company. The Board has established standards to assist it in making determinations of director independence. These standards conform to, or are more exacting than, the independence requirements provided in the NYSE listed company rules. The Company’s director independence standards are set forth as Annex A to our Governance Guidelines.

All members of the Audit, Compensation and Directors and Governance Committees must be independent directors under the NYSE listed company rules and the standards set forth in the Company’s Governance Guidelines. Members of the Audit Committee must also satisfy a separate Securities and Exchange Commission (“SEC”) and NYSE independence requirement, which provides that they may not be affiliates and may not accept directly or indirectly any consulting, advisory or other compensatory fee from the Company or any of its subsidiaries, other than compensation received in their capacity as members of the Board or any committee of the Board. The Board evaluated each member of the Compensation Committee under the additional NYSE compensation committee member independence standards and also determined that these members qualify as “non-employee directors” (as defined under Rule 16b-3 under the Securities Exchange Act of 1934).

Under our Governance Guidelines, if a director whom the Board has deemed independent has a change in circumstances or relationships that might cause the Board to reconsider that determination, he or she must immediately notify the chairman of the Board and the chair of the Directors and Governance Committee.

REVIEW OF RELATED PERSON TRANSACTIONS

The Company maintains a written Policy Regarding Related Person Transactions, which sets forth standards and procedures for the review and approval or ratification of transactions between the Company and related persons. The policy is administered by the Directors and Governance Committee with assistance from the Company’s Corporate Secretary.

In determining whether to approve or ratify a related person transaction, the Directors and Governance Committee will review the facts and circumstances including: the commercial reasonableness of the transaction; the benefits of the transaction to the Company; the availability of other sources for the products or services involved in the transaction; the materiality and nature of the related person’s direct or indirect interest in the transaction; the potential public perception of the transaction and the potential impact of the transaction on the independence of any of the Company’s directors. The Directors and Governance Committee will approve or ratify a related person transaction only if the Committee determines that the related person transaction is in, or is not inconsistent with, the best interests of the Company and its stockholders.

If the Directors and Governance Committee determines not to approve or ratify a related person transaction, the transaction will not be entered into or continued. No member of the Directors and Governance Committee will participate in any review or determination if the Committee member or any of his or her immediate family members is the related person.

See the discussion under “Transactions with Management and Others” on page 75.

STOCKHOLDER RECOMMENDATIONS AND NOMINATIONS FOR DIRECTOR CANDIDATES

Stockholders may recommend or nominate director candidates in writing to the Company’s Corporate Secretary. All stockholder recommendations for director candidates are considered, and they are evaluated in the same manner as other director candidates. Stockholders making nominations for director elections must meet the requirements described in Article III of our bylaws. The notice of nomination also must meet bylaw requirements, including as the procedures and information required. Recommendations and notices of nomination should be delivered to the Company’s Corporate Secretary at our principal executive offices: Marsh & McLennan Companies, Inc., Attn: Directors and Governance Committee, c/o Katherine J. Brennan—Corporate Secretary, 1166 Avenue of the Americas, New York, New York 10036-2774. See the discussion under “Submission of Stockholder Proposals and Other Items of Business for 2022 Annual Meeting” on page 80.

DIRECTOR ELECTION VOTING STANDARD

The Company’s bylaws provide that, in an uncontested election of directors, such as this one, where the number of nominees does not exceed the number of directors to be elected, a director nominee must receive more votes cast “for” than “against” his or her election in order to be elected to the Board.

In connection with the Company’s majority voting standard for director elections, the Board has adopted the following procedures, which are set forth more fully in Section E.3 of our Governance Guidelines:

•

The Board shall nominate for election only director candidates who agree to tender to the Board an irrevocable resignation that will be effective upon (i) a director’s failure to receive the required number of votes for re-election at the next meeting of stockholders at which he or she faces re-election and (ii) the Board’s acceptance of such resignation.

•

Following a meeting of stockholders at which an incumbent director who was a nominee for re-election does not receive the required number of votes for election, the Directors and Governance Committee shall make a recommendation to the Board as to whether to accept or reject such director’s resignation. Within 90 days following the certification of the election results, the Board shall decide whether to accept or reject the director’s resignation and shall publicly disclose that decision and its rationale.

•

If the Board accepts a director’s resignation, the Directors and Governance Committee will recommend to the Board whether to fill the resultant vacant Board seat or reduce the size of the Board.

COMMUNICATING WITH DIRECTORS

Holders of the Company’s common stock and other interested parties may send communications to the Board of Directors, the independent chairman, any of the directors or the independent directors as a group by mail (addressed to Katherine J. Brennan—Corporate Secretary, at the address shown below), online at ethicscomplianceline.com or by telephone (local dialing instructions can be found at ethicscomplianceline.com). Items unrelated to the directors’ duties and responsibilities as Board members may be excluded by the Corporate Secretary, including solicitations and advertisements, product-related communications, surveys and job referral materials such as resumes.

BOARD COMPOSITION, LEADERSHIP AND SIZE

At the 2021 annual meeting, stockholders will vote on the election of thirteen (13) directors. H. Edward Hanway currently serves as the Board’s independent chairman.

The only member of management who serves on the Board is Daniel S. Glaser, the Company’s President and Chief Executive Officer. The position of chairman of the Board has been held by an independent director since 2005. The Board believes that this currently is the best leadership structure for the Company.

LOGO

DIRECTOR QUALIFICATIONS

As provided in our Governance Guidelines, all directors must demonstrate the highest standards of ethics and integrity, must be independent thinkers with strong analytical ability and must be committed to representing all of the Company’s stockholders rather than any particular interest group. In addition to these characteristics, our Governance Guidelines provide that each director candidate be evaluated by the Board against the following criteria: (1) the candidate’s personal and professional reputation and background; (2) the candidate’s knowledge and experience with the company’s businesses and industries; (3) the candidate’s experience with businesses or other organizations comparable to the Company in terms of size or complexity; (4) the interplay of the candidate’s skills and experience with those of the incumbent directors; (5) the extent to which the candidate would provide substantive expertise that is currently sought by the Board or any committees of the Board; (6) the candidate’s ability to commit the time necessary to fulfill a director’s responsibilities; (7) relevant legal and regulatory requirements and evolving best practices in corporate governance; (8) the gender, racial, ethnic and cultural diversity of each potential candidate and (9) any other criteria the Board deems appropriate.

BOARD OF DIRECTORS AND COMMITTEES (Continued)

BOARD DIVERSITY

We are committed to maintaining a diverse and inclusive Board. We appointed our fifth consecutive diverse director to our Board in 2020. In the past 10 years, we have appointed eight independent directors, seven of whom are diverse.

Of our 13 directors, three are men who are racially or ethnically diverse and three are women. Daniel S. Glaser, the Company’s President and Chief Executive Officer, is a member of the 30% Club, a global campaign to increase gender diversity at board and senior management levels.

Our Governance Guidelines specify that the gender, racial, ethnic and cultural diversity of each potential director candidate be considered by the Board. In its recruitment process, the Directors and Governance Committee and the Board seek to reflect gender, race, ethnic and cultural diversity in the pool of director candidates. Further, our Governance Guidelines provide that, to the extent that a search firm is retained to identify external candidates for Board membership, the Board will instruct the search firm to reflect gender, race, ethnic and cultural diversity in the initial pool of candidates. The Directors and Governance Committee and the Board also consider gender, race, ethnic and cultural diversity in the director nomination process.

BOARD REFRESHMENT

The Board is committed to effective succession planning and refreshment. Four directors have joined since 2016, with our newest director joining in 2020, enhancing the Board’s breadth and depth of experience and diversity. The average tenure of our directors is ten years. In deciding whether to nominate an incumbent director for re-election, the Board considers many factors, including tenure and an assessment of independence. The Board believes that term limits might arbitrarily deprive the Board of the contributions of directors who have valuable insight, developed over time, into the Company and its industries. The Board believes that a mix of director tenures provides fresh viewpoints, institutional knowledge and historical perspective.

RETIREMENT

Our Governance Guidelines require our independent directors to resign no later than at the annual meeting of stockholders following their 75th birthday. Any director who is an employee of the Company will resign from the Board when his or her employment ends.

ATTENDANCE

The Board held ten meetings during 2020. The average attendance by directors at meetings of the Board and its committees held during 2020 was approximately 98%. All directors attended at least 75% of the meetings of the Board and committees on which they served. The Board’s policy is to have all directors attend the annual meetings of stockholders. All directors attended the 2020 annual meeting of stockholders.

EXECUTIVE SESSIONS

Our independent directors meet in executive session without management at regularly scheduled multi-day Board meetings. In 2020 they held six executive sessions, which were presided over by the independent chairman of the Board. In addition, the members of the Audit, Compensation and Directors and Governance Committees meet in executive session without management at regularly scheduled committee meetings.

BOARD AND COMMITTEE EVALUATIONS

Our Governance Guidelines provide that the Directors and Governance Committee oversees an annual evaluation of the Board’s performance and effectiveness. In addition, the charters for the Audit, Compensation, Directors and Governance, Finance and ESG Committees provide that each committee evaluates its own performance annually.

Board Evaluations

The annual evaluation of the Board focuses on its contribution to the Company over the preceding year, including areas in which the Board or management believes the Board could enhance its future contributions. More generally, directors are encouraged to make suggestions at any time for improving the Board’s practices.


12		Marsh & McLennan Companies, Inc. Notice of Annual Meeting and 2021 Proxy Statement

BOARD OF DIRECTORS AND COMMITTEES (Continued)

An overview of the Board self-evaluation process is provided below.


Overview of Board Self-evaluation Process
Determine Form and Content of Self-Evaluation		• The Directors and Governance Committee determines the form and content of the evaluation each year, taking into account director and stockholder feedback and best practices. The Directors and Governance Committee has considered whether to engage a third party for the evaluation.
Discuss in Executive Session		• The self-evaluation takes place in executive session using a compilation of unattributed responses, which is provided to directors in advance of the meeting.
Respond to Feedback		• Based on director feedback, changes are considered and, as appropriate, implemented.

For the evaluation of 2020, the Directors and Governance Committee considered the form of the evaluation and determined to use a questionnaire soliciting qualitative commentary and quantitative ratings from each director. The questionnaire begins with open-ended discussion questions and also solicits the directors’ views on topics such as:

•

the Board’s key priorities

•

the Board’s knowledge base

•

fulfillment of the Board’s and committees’ responsibilities

•

the Board’s interaction with management

•

the Board’s structure, composition and committees

•

Board meetings and related processes

Recent changes to the questionnaire include adding a discussion question about which changes in 2020 to maintain, modify or restore and deleting discussion questions that have not solicited meaningful feedback. Changes made in response to director feedback from the Board evaluation have included changing committee assignments.

Committee Evaluations

The Audit, Compensation, Directors and Governance, Finance and ESG Committees evaluate their own performance annually pursuant to their respective charters. Material is provided in advance to assist the committee with assessing its performance of its responsibilities under its charter and our Governance Guidelines. These materials include questions for discussion, summaries of the committee’s activities and responsibilities and feedback from the Board self-evaluation regarding the committee. Committee self-evaluations are conducted in executive session.

BOARD OF DIRECTORS AND COMMITTEES (Continued)

COMMITTEES

Our Board maintains an Audit Committee, a Compensation Committee, a Directors and Governance Committee, a Finance Committee, an ESG Committee and an Executive Committee to assist the Board in discharging its responsibilities. Following each committee meeting, the respective committee chair reports the highlights of the meeting to the full Board.

Membership on each of the Audit, Compensation and Directors and Governance Committees is limited to independent directors as required by the Company, the listing standards of the NYSE and the SEC’s independence rules. The ESG and Finance Committees must consist of a majority of independent directors as required by the Company. Each of these committees is governed by a charter, which is available on our website at mmc.com/about/corporate-governance.html.

Audit Committee

The Audit Committee is charged, among other things, with assisting the Board in fulfilling its oversight responsibilities with respect to:

•

the integrity of the Company’s financial statements;

•

the qualifications, independence and performance of our independent registered public accounting firm;

•

the performance of the Company’s internal audit function;

•

the Company’s policies and implementation of systems and controls designed to promote ethical behavior;

•

compliance by the Company with legal and regulatory requirements; and

•

the Company’s enterprise risk management programs and processes.

The Audit Committee selects, oversees and approves, pursuant to a pre-approval policy, all services to be performed by our independent registered public accounting firm. The Company’s independent registered public accounting firm reports to the Audit Committee.

All members of the Audit Committee are “financially literate,” as required by the NYSE and determined by the Board. The Board has determined that Anthony K. Anderson, Bruce P. Nolop and Lloyd M. Yates have the requisite qualifications to satisfy the SEC definition of “audit committee financial expert.”

Compensation Committee

The primary responsibilities of the Compensation Committee are to:

•

evaluate the performance and determine the compensation of our chief executive officer;

•

review and approve the compensation of our other senior executives;


14		Marsh & McLennan Companies, Inc. Notice of Annual Meeting and 2021 Proxy Statement

BOARD OF DIRECTORS AND COMMITTEES (Continued)

•

review certain key human resource strategic activities, including those relating to diversity, training and recruitment; and

•

oversee and discharge its responsibilities for the Company’s incentive compensation plans for our senior executives and equity-based award plans.

Meeting Schedule. The Compensation Committee met seven times in 2020, including a special meeting in February to complete its annual review of, and make decisions on, executive compensation. Decisions relating to significant matters are usually presented to the Compensation Committee and discussed at more than one meeting to allow for full consideration of the implications and possible alternatives before a final decision is made. The Compensation Committee receives support from its independent compensation consultant and the Company’s management, including the Company’s human resources staff, as described below. At each of its meetings, the Compensation Committee meets in executive session and without management present. The independent compensation consultant attends portions of the executive sessions.

The Compensation Committee may delegate all or a portion of its duties and responsibilities to the chair of the Compensation Committee or a subcommittee of the Compensation Committee. If necessary, the chair is authorized to take action on behalf of the Compensation Committee between its regularly scheduled meetings, within prescribed guidelines. If any such action is taken, the chair reports such action to the Compensation Committee at its next regularly scheduled meeting.

Independent Compensation Consultant. The Compensation Committee has engaged Pay Governance LLC as its independent compensation consultant to support the Compensation Committee in performing its duties and to provide analysis and make recommendations to the Compensation Committee regarding our executive compensation program. The independent compensation consultant reports directly to the Compensation Committee and provides advice and analysis solely to the Compensation Committee. The independent compensation consultant supports the Compensation Committee by:

•

participating in meetings and executive sessions of the Compensation Committee to advise the Compensation Committee on specific matters that arise;

•

offering objective advice regarding the compensation and policy recommendations presented to the Compensation Committee by the Company’s management, including senior members of the Company’s human resources staff; and

•

providing data regarding the compensation practices of comparable companies.

The Compensation Committee requested and received advice from the independent compensation consultant with respect to all significant matters addressed by the Compensation Committee during 2020. Except for the services provided to the Compensation Committee, neither the individual compensation consultant nor Pay Governance LLC nor any of its affiliates provided any services to the Company or its affiliates in 2020.

The Compensation Committee assessed the work of Pay Governance LLC during 2020 pursuant to SEC rules and concluded that Pay Governance’s work did not raise any conflict of interest.

Company Management. The Company’s management, including the Company’s human resources staff, supports the Compensation Committee by:

•

developing meeting agendas in consultation with the chair of the Compensation Committee and preparing background materials for Compensation Committee meetings;

•

making recommendations to the Compensation Committee on the Company’s compensation philosophy, governance initiatives and short-term and long-term incentive (“LTI”) compensation design, and by providing input regarding the individual performance component of annual bonus awards; and

•

responding to actions and initiatives proposed by the Compensation Committee.

In addition, our President and Chief Executive Officer provides recommendations with respect to the compensation of our other senior executives.

Our President and Chief Executive Officer, senior members of the Company’s human resources staff and internal legal counsel attended Compensation Committee meetings when invited but were not present for executive sessions or for any discussion of their own compensation.


		Marsh & McLennan Companies, Inc. Notice of Annual Meeting and 2021 Proxy Statement			15

BOARD OF DIRECTORS AND COMMITTEES (Continued)

Timing and Procedures of Equity-Based Compensation Awards. Annual awards under our LTI compensation program are approved at a prescheduled meeting of the Compensation Committee each February and, consistent with our historical practice, are granted on that same date.

In addition, the Compensation Committee periodically grants restricted stock unit awards to newly hired senior executives and to continuing senior executives for increased responsibilities that accompany changes in position and for retention purposes. These awards are approved at prescheduled meetings of the Compensation Committee. The Compensation Committee has also authorized our President and Chief Executive Officer to make such awards to individuals who are not senior executives, subject to prescribed parameters. These awards are granted on the first calendar day of the month following approval of the award by the Compensation Committee or our President and Chief Executive Officer, as applicable. In the event that an award is approved prior to an individual’s start date with the Company, the award will be granted on the first calendar day of the first month on or following the individual’s start date; however, if an award is approved contingent on the award recipient providing documentation supporting the forfeiture of compensation from a former employer and that documentation has not been provided as of the individual’s start date, the award will be granted on the first calendar day of the month following the provision of such documentation and acceptance by the Company.

Typically, equity-based awards are denominated as a dollar value and then converted into a number of performance stock units, restricted stock units or stock options. The number of performance stock units or restricted stock units is determined based on the fair market value of the Company’s common stock, which is defined as the average of the high and low trading prices of the Company’s common stock on the trading day immediately preceding the grant date. The number of stock options is determined based on the grant date fair value of a stock option to purchase a share of the Company’s common stock. The grant date fair value of stock options and performance stock units is determined in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation–Stock Compensation (“FASB ASC Topic 718”). Stock options have an exercise price equal to the average of the high and low trading prices of the Company’s common stock on the trading day immediately preceding the grant date. We believe that our equity-based compensation grant procedures effectively protect against the manipulation of grant timing for employee gain.

The Company’s human resources staff regularly monitors, and updates the Compensation Committee on, the use of shares of the Company’s common stock for equity-based awards and the number of shares available for future awards under our equity-based compensation plans. As part of the process of granting annual LTI compensation, the Compensation Committee considers share use and equity run rate (a measure of the potential dilutive impact of the Company’s equity award program, defined as the number of shares underlying awards granted plus the number of shares underlying awards assumed upon acquisition (if any), divided by weighted average common shares outstanding) so that annual LTI awards, and the extent to which shares of the Company’s common stock are used for those awards, are maintained at a reasonable level.

Directors and Governance Committee

The Directors and Governance Committee’s duties and responsibilities include, among other things:

•

assisting the Board by identifying, considering and recommending, consistent with criteria approved by the Board, qualified candidates for election as directors, including the slate of directors to be nominated by the Board for election at the Company’s annual meeting of stockholders;

•

recommending Board committee assignments;

•

overseeing the development and implementation of succession planning for the Company’s chief executive officer; and

•

developing and recommending to the Board the Company’s Governance Guidelines, including taking a leadership role in shaping the Company’s corporate governance.

2020 HIGHLIGHTS

Supporting Our Colleagues Through COVID-19

LOGO

• As COVID-19 spread around the world, we prioritized the health and well-being of our colleagues.

• Early in the crisis, we were one of the first companies to commit to protect jobs during the thick of the pandemic.

• We implemented 2020 salary increases as planned with no pandemic-related pay cuts.


28		Marsh & McLennan Companies, Inc. Notice of Annual Meeting and 2021 Proxy Statement

EXECUTIVE COMPENSATION (Continued)

2020 HIGHLIGHTS (continued)


		• We accrued broad-based 2020 bonus pools in line or above 2019 levels, commensurate with performance. • We expanded our employee assistance program to cover over 80% of colleagues worldwide, extended telemedicine to 26 countries and established a $5 million fund to support colleagues experiencing personal financial hardship stemming from the pandemic. • We achieved record colleague engagement scores, with increases in all of our businesses and across all key engagement items.
Leading the Change for Racial and Social Justice		• When communities around the world joined in solidarity last year to confront racial and social injustice, we focused on the gaps in hiring diversity and real inclusion at Marsh McLennan—and introduced our “Leading the Change” program to address them with urgency. • We created a Race Advisory Council to advise the Executive Committee so diverse perspectives are considered in decision-making, especially decisions that affect our colleagues. • We committed to hire more Black colleagues at every level and launched new initiatives to support career development, connection and empowerment for our Black colleagues. • We also committed $5 million over the next three years to support nonprofit organizations that advocate for equity in the Black community and doubled the Company’s match for colleague donations to organizations that advocate for social justice.
Positioning Our Business For the Future		• We accelerated collaboration and cross-business activity and continued to move toward a more integrated enterprise. • We rapidly pivoted our business in response to the COVID-19 pandemic to support clients and develop new solutions, including Oliver Wyman’s Pandemic Navigator, a leading disease-progression model; a supplemental insurance product for individuals affected by COVID-19; public-private partnerships for pandemic risk insurance; and return-to-office and “new normal” strategies. • We successfully completed the integration of Jardine Lloyd Thompson plc (“JLT”), the largest acquisition in the Company’s 150-year history that is providing clients with enhanced talent, capabilities and geographic footprint. • We continued to build out Marsh & McLennan Agency through acquisitions, closing on eight transactions representing approximately $235 million of annualized revenue, including Assurance Holdings.
Financial Objectives		• In 2020, Marsh McLennan delivered strong performance as we successfully navigated the global health and economic crises to execute on our long-term financial and strategic objectives. • GAAP EPS increased 16%, and we delivered 7% growth in adjusted EPS* despite a challenging business environment due to COVID-19. • We generated $17 billion of revenue, an increase of 3% compared with 2019. We achieved 1% growth in underlying revenue. • Our *overall adjusted margin increased 120 basis points**, our 13^th consecutive year of margin improvement.

EXECUTIVE COMPENSATION (Continued)

2020 HIGHLIGHTS (continued)



				• With JLT cost savings well ahead of schedule, we are on track to deliver more than $425 million of run-rate savings by the end of 2021 and exceed our original target of $250 million. * Please see Exhibit A for a reconciliation of our non-GAAP financial measures to GAAP financial measures and related disclosures.
		Capital Management		• We increased our quarterly dividend from $0.455 to $0.465 per share beginning in the third quarter of 2020, resulting in an annual dividend increase of 5.7%, from $1.74 to $1.84. Our dividend has increased every year since 2010. • We remained on track with our deleveraging plans through earnings growth and a firm-wide emphasis on expense discipline.
		Stock Performance		• Our 2020 total stockholder return (“TSR”) was 6.8%. • Our five-year annualized TSR of 18.3% outperformed the S&P 500^® index TSR by 3.1 percentage points.
		Executive Compensation		• In February 2020, prior to the onset of the COVID-19 pandemic, the Compensation Committee set rigorous performance targets for our annual bonus plan and long-term incentive (“LTI”) plan and did not subsequently reset or adjust targets despite the impact of COVID-19. • In February 2021, the Compensation Committee assessed management’s performance against the original 2020 objectives and resiliency in responding to the pandemic. The Compensation Committee determined bonuses that were above-target yet below last year’s levels for all of our named executive officers, except Ms. Ferland. As Ms. Ferland successfully completed her second year leading the Mercer business, the Compensation Committee determined her annual bonus above last year’s level and increased her annual LTI award to recognize her performance and appropriately position her compensation compared to internal peers. • We achieved three-year annualized adjusted EPS growth of 8.4% for our 2018 performance stock unit awards. This was above our 8% target for the award and resulted in a payout at 110% of target. Despite the impact of the pandemic on our financial performance, the Compensation Committee did not subsequently reset or adjust the 8% target for three-year annualized adjusted EPS growth applicable to the 2018, 2019 or 2020 performance stock unit awards. • Starting with the 2020 LTI awards, we made two key changes to the design of our annual LTI design in order to more closely align executive rewards with stockholder interests. We increased the proportion of performance stock award units to 50% for our senior executives and added a relative TSR modifier based on the Company’s three-year TSR versus S&P 500^® companies. In making these decisions, the Compensation Committee took into account stockholder views.

Annual LTI awards as determined by the Compensation Committee are denominated in U.S. dollars and granted as a combination of stock options and PSUs. For stock options, 50% of the LTI value shown in the table is converted into a number of stock options based on the grant date fair value per share using the Black-Scholes value. For PSUs, 50% of the LTI value shown in the table is converted into a number of PSUs based on the fair market value of Company common stock, which is equal to the average of the high and low trading prices of shares of the Company common stock on the trading date immediately preceding the date of grant. The grant date fair value of the PSUs, as calculated in accordance with ASC Topic 718, is determined using a Monte Carlo simulation model since payouts are based in part on a relative TSR modifier, which is a market condition. In addition, stock options and PSUs granted are rounded up to the nearest whole number.

2020 “Say on Pay” Vote and Stockholder Engagement

LOGO

“Say on Pay” Vote

At our 2020 Annual Meeting of Stockholders, we held a nonbinding advisory vote with respect to the compensation of our named executive officers (commonly referred to as a “say on pay” vote). Approximately 94% of the votes cast on the say on pay proposal were voted in favor of our executive compensation philosophy, policies and practices.

Stockholder Engagement

Following our 2020 Annual Meeting of Stockholders, members of our management, at the direction of the Compensation Committee, discussed our executive compensation policies and practices with a number of our large institutional stockholders and the major proxy advisory firms. These discussions were favorable, consistent with our 94% approval rate in 2020.

Over the years, certain stockholders have expressed a preference for a larger proportion of performance stock unit awards and for a relative performance measure in those awards. The Compensation Committee took these views into account in the long-term incentive awards granted in 2020, when it increased the proportion of performance stock unit awards to 50% and added a relative TSR modifier based on the Company’s three-year TSR versus S&P 500^® companies. We received positive feedback on these changes during our discussions with large institutional stockholders and the major proxy advisory firms.

The Compensation Committee is committed to ongoing engagement with our stockholders and the major proxy advisory firms and to undertaking these outreach efforts annually.

KEY EXECUTIVE COMPENSATION POLICIES AND PRACTICES


Stockholder Aligned Executive Compensation Program	✓	Our senior executives have a high percentage of variable (“at risk”) pay.
Stockholder Aligned Executive Compensation Program	✓	Long-term incentive compensation for our senior executives is delivered in stock options and performance stock unit awards, the value of which depends on stock price appreciation or achievement of specific Company financial objectives and the Company’s relative TSR versus S&P 500^® companies.
	✓	We generally mitigate the potential dilutive effect of equity-based awards through our share repurchase program.
	✓	Our Compensation Committee has an independent compensation consultant.
Compensation Recovery Policies	✓	We have clawback policies for senior executive annual bonus awards and for equity-based compensation.
Severance and Change in Control	✓	Severance protections for our senior executives, including our CEO, are at a 1x multiple of base salary and bonus, with a pro-rata bonus for the year of termination. Further, we are required as a matter of policy to obtain stockholder approval for severance agreements with certain senior executives if they provide for cash severance that exceeds 2.99 times the executive’s base salary and three-year average annual bonus award.
	✓	We provide “double-trigger” vesting of equity-based awards and payment of severance benefits following a change in control of the Company.
	✓	We do not provide golden parachute excise tax gross-ups in connection with a change in control of the Company.
Say on Pay	✓	We hold an advisory vote on named executive officer compensation each year.
	✓	Stockholder support for our executive compensation program has been consistently strong with an approval rate of 94% in 2020 and 93% or higher since 2013.

EXECUTIVE COMPENSATION DESIGN, ELEMENTS AND PROCESS

Our executive compensation program is governed by four principles:

Aligning with stockholder value creation with a focus on balancing risk and reward in compensation programs, policies and practices

Supporting a strong performance culture through short-term and long-term variable compensation, with the ability to differentiate among individuals based upon actual results

Setting target compensation at competitive levels in markets where we operate with flexibility to recognize different business models and markets for talent

Maximizing colleagues’ perceived value of our programs through transparent processes and communication

Elements of Compensation

The principal elements of our executive compensation program are base salary, annual bonuses and annual LTI awards. The Compensation Committee believes that each compensation element, and all of these elements combined, are important to maintain an executive compensation program that is competitive, performance-based and stockholder-focused.

Our integrated compensation framework heavily weights variable compensation to reward achievements against pre-established, quantifiable financial performance objectives and individual strategic performance objectives. In addition, because a significant portion of variable compensation is delivered in the form of equity-based awards, the value ultimately realized by our senior executives from these awards depends on stockholder value creation as measured by the future performance of our stock price and also TSR versus S&P 500^® companies, which is a modifier for payouts of our PSU awards granted since 2020.

As of December 31, 2020, variable compensation represented approximately 91% of our CEO’s target total direct compensation and about 83% for our other named executive officers, as shown in the following charts.

EXECUTIVE COMPENSATION (Continued)



Element of Total Compensation	Target Total Compensation Mix	Description

Base Salary		Base salary is intended to provide a fixed level of compensation that is appropriate given a senior executive’s role in the organization, his or her skills and experience, the competitive market for his or her position and internal equity considerations. A senior executive’s base salary is set forth in his or her employment letter and may be adjusted when the Compensation Committee determines an adjustment is appropriate to reflect a change in these factors.

Annual Bonus		Our annual bonus is a variable pay program intended to link cash-based incentive compensation to the financial performance of our Company and our businesses and each senior executive’s achievement of pre-established individual strategic objectives. The Compensation Committee takes a holistic approach to assessing performance and determining the actual bonus award for each senior executive. The Compensation Committee believes that annual bonus awards should be based on the achievement of objective, measurable financial results and how those results are achieved. In addition, the Compensation Committee believes it is important to measure individual executive performance against his or her achievement toward strategic objectives and other Company priorities. After the end of the year, each senior executive’s performance was assessed by Mr. Glaser and the Compensation Committee (and, in the case of Mr. Glaser’s performance, solely by the Compensation Committee). A senior executive’s target annual bonus is set forth in his or her employment letter and may be adjusted when the Compensation Committee determines an adjustment is appropriate or necessary to reflect a change in his or her responsibilities, the competitive market for talent or internal equity considerations. The target annual bonuses for our named executive officers for 2020 are set forth in “Determination of 2020 Annual Bonuses” on page 40. The Compensation Committee increased Mr. Doyle’s target annual bonus from $2,250,000 to $2,500,000 in early 2020 and Ms. Ferland’s target annual bonus from $1,700,000 to $1,900,000 in early 2021. Both increases were based on a review of the competitive market and internal equity considerations.

Annual LTI Award		Annual LTI compensation is a variable pay program intended to align the financial interests of our senior executives with maximizing the return to our stockholders. Starting in 2020, the Compensation Committee set our LTI mix for senior executives at 50% performance stock units and 50% stock options. The payout of PSU awards granted since 2020 is based on three-year annualized adjusted EPS growth and our three-year TSR versus S&P 500^® companies. The Compensation Committee reviews the mix of equity-based awards each year.

EXECUTIVE COMPENSATION (Continued)

EXECUTIVE COMPENSATION DETERMINATIONS

The Compensation Committee takes a total compensation approach in setting the pay of our senior executives and makes decisions regarding base salary, annual bonuses and annual LTI awards in February of each year. This approach enables the Compensation Committee to evaluate performance on a consistent basis each year and to consider the appropriate level of fixed and variable compensation within each senior executive’s total compensation package.

While the Compensation Committee recognizes that elements of compensation may be interrelated, it does not require or assume any fixed relationship among the various elements of compensation within the total direct compensation framework or between the compensation of our CEO and that of any other senior executive. In addition, accrued pension and amounts realized or realizable under previously granted equity-based awards did not influence the Compensation Committee’s decisions.

The Compensation Committee considers the recommendations of our CEO when determining the compensation of our other senior executives.

Base Salary

The Compensation Committee did not adjust the base salaries of our named executive officers during 2020.

Annual Bonus

The Compensation Committee determined the 2020 annual bonus awards for our named executive officers using the following framework:

LOGO

The Compensation Committee established the annual bonus framework and rigorous performance targets in early 2020, prior to the onset of the COVID-19 pandemic. For the remainder of the year, the Compensation Committee monitored the impact of COVID-19 and used a “resiliency scorecard” to guide its assessment of senior executive performance in responding to the crisis. The scorecard included categories such as clients, colleagues, JLT integration, expense management, liquidity, cash flow and capital expenditures.

In determining the 2020 annual bonus awards, each senior executive’s target annual bonus was allocated between financial and strategic performance according to weightings associated with his or her position. The Compensation Committee then assessed financial performance and each senior executive’s strategic performance and determined a payout level for each portion of the senior executive’s target annual bonus.

The multiplier for Company financial performance as reflected by adjusted EPS growth (as modified for executive compensation purposes) versus target was determined and applied to the sum of the payout levels for financial and strategic performance for each senior executive.

Using this result, the Compensation Committee then conducted a qualitative assessment, including factors showing management’s resiliency, to determine the actual bonus award for each senior executive. The Compensation Committee believes that the use of judgment in the qualitative assessment helps reward performance appropriately, particularly on a year-to-year basis.

The financial performance factor for net operating income ranged from 0% to 150% of the target level as indicated in the following table:



Performance Level	Performance as a % of Target		Financial Performance Factor

Maximum	³	110%		150%

Target		100%		100%

Note: Interpolation is used to determine the performance factor for performance as a percentage of target between threshold/target or target/maximum. In the event of performance below threshold, the Compensation Committee would exercise its discretion to determine a financial performance factor from 0% up to 50%.

2020 Financial Performance

For 2020, the financial performance measure for all senior executives was Company or business net operating income, as applicable, as modified for executive compensation purposes. The Compensation Committee set challenging targets for our named executive officers to align with our 2020 objective of driving strong earnings growth across the Company. The targets were maintained as originally set despite the COVID-19 pandemic and its impact on our financial performance.

Performance targets for 2020 were set above the targeted and actual performance for 2019. Performance targets were based on threshold, target and maximum levels in dollars rather than growth rates. Target and actual results in the table below are expressed as a percentage of prior-year results.


Name	Measure	2020 Actual as % of Prior-Year Result		2020 Target as % of Prior-Year Result		2020 Actual as % of Target		2020 Financial Performance Factor

2020 Strategic Performance

In early 2020, the Compensation Committee reviewed each named executive officer’s strategic objectives, relating to operational performance, growth initiatives, risk management and human capital, including diversity and inclusion.


		Marsh & McLennan Companies, Inc. Notice of Annual Meeting and 2021 Proxy Statement			37

EXECUTIVE COMPENSATION (Continued)

At the beginning of 2021, the Compensation Committee reviewed the strategic accomplishments for each named executive officer for 2020. The Compensation Committee and Mr. Glaser (and, in the case of Mr. Glaser, solely the Compensation Committee) assessed each named executive officer’s strategic performance as above target for the year and determined a performance factor ranging up to a maximum of 150% for 2020 strategic performance.

The Compensation Committee considered the following in its assessment of each named executive officer’s performance:


Name and Title		Strategic Accomplishments

2020 Multiplier for Company Financial Performance

The financial performance factor for the Company is measured by annual adjusted EPS growth, resulting in a 0.70x to 1.30x multiplier as indicated in the following table:

Performance Level

Adjusted EPS Growth versus Target

Multiplier

Maximum

Target plus 2 percentage points (or higher)

Note: Interpolation is used to determine the multiplier for a percentile ranking between minimum/target or target/maximum.

The financial performance measure used for adjusted EPS growth in the 2020 annual bonus framework is defined in “Definitions of Financial Performance Measures” on page 45.

For 2020, the target was set at 8% and was maintained at that level despite the COVID-19 pandemic and its impact on financial performance. Using the framework described above, our annual adjusted EPS growth as modified for executive compensation purposes relating to the 2020 bonus framework was 7.5% resulting in a multiplier of 0.93x.

2020 Qualitative Assessment

The Compensation Committee believes that the use of judgment in making final bonus award decisions helps reward performance appropriately on a year-to-year basis and also on an internal equity basis among senior executives. In addition to performance as measured against the previously described financial and strategic objectives, the Compensation Committee also assessed how these objectives were achieved, including by considering factors showing management’s resiliency. For each senior executive, the Compensation Committee also considered his or her current-year performance and bonus award vis-à-vis his or her prior-year performance and bonus award; compensation relative to peers at direct competitors; and his or her total direct compensation. The Compensation Committee also reviewed the Company’s relative financial performance, including for TSR against peer companies and the S&P 500^® Index.

Annual LTI Awards

The Compensation Committee determined the 2021 annual LTI awards granted to named executive officers would comprise stock options and performance stock units, as summarized in the following table:


Award Type		Performance Alignment
Stock Options		Rewards stock price appreciation and the creation of stockholder value
Performance Stock Units		Rewards the achievement of specific Company financial objectives and relative TSR versus S&P 500^® companies

The Compensation Committee had made two key changes starting in 2020, as reflected above, in order to more closely align senior executive rewards with stockholder interests. In making these decisions, the Compensation Committee took into account views expressed by certain stockholders over the years.

Increased proportion of PSUs. Starting in 2020, the Compensation Committee increased the proportion of performance stock unit (PSU) awards to 50%, eliminating the 25% previously allocated to restricted stock unit (RSU) awards.

LOGO

Relative TSR modifier. Also starting in 2020, the Compensation Committee added a relative TSR modifier to the PSUs based on the Company’s three-year TSR versus S&P 500^® companies. The Compensation Committee selected S&P 500^® companies as the comparator group given that a broad index is commonly used by other companies that have relative TSR as a performance measure. In addition, we compete for “investment dollars” against other S&P 500^® companies rather than narrowly against our peer group for executive compensation, which is relatively small and subject to potentially significant change over time.

Determination of 2021 Annual LTI Awards

The annual equity-based awards granted to our senior executives are determined by the Compensation Committee as part of its annual total compensation review. In determining the awards, the Compensation Committee considers the senior executive’s performance and his or her expected future contributions to the Company’s performance along with external market competitiveness, internal equity comparisons and the target LTI award set forth in the senior executive’s employment letter. Mr. Glaser also provides LTI award recommendations for senior executives other than himself.

EXECUTIVE COMPENSATION (Continued)

The annual LTI awards granted to our named executive officers in February 2021 are shown in the following table. They are not reflected in the “2020 Summary Compensation Table” on page 51 because the awards were made after the end of the 2020 fiscal year.


	Annual LTI Awards Granted in 2021¹
	Stock Options		Performance Stock Units		Total
Mr. Glaser	$	6,250,000	$	6,250,000	$	12,500,000

Ms. Ferland		1,200,000		1,200,000		2,400,000

Annual LTI awards as determined by the Compensation Committee are denominated in U.S. dollars and granted as a combination of stock options and PSUs. For stock options, the value shown in the table was converted into a number of stock options based on the grant date fair value per share using the Black-Scholes value. For PSUs, the value shown in the table was converted into a number of PSUs based on the fair market value of Company common stock, which was equal to the average of the high and low trading prices of shares of the Company common stock on the trading date immediately preceding the date of grant. The grant date fair value of the PSUs, as calculated in accordance with ASC Topic 718, is determined using a Monte Carlo simulation model since payouts are based in part on a relative TSR modifier, which is a market condition. In addition, stock options and PSUs granted are rounded up to the nearest whole number.

The value ultimately realized from these awards is contingent on the named executive officer’s continued service, except in certain circumstances, such as retirement. The value also depends on the future performance of our stock price and, for PSU awards, achieving specific Company financial objectives and the Company’s relative TSR versus S&P 500^® companies. The terms and conditions of these awards are described in the narrative following the “2020 Grants of Plan-Based Awards Table” on page 54.

PSU Awards

The performance measure for PSU awards, which represent 50% of 2021 annual LTI compensation for our senior executives, is adjusted EPS growth as modified for executive compensation purposes and measured on a three-year annualized growth rate basis. The PSUs granted in 2020 and 2021 also include a modifier based on the Company’s three-year TSR versus S&P 500^® companies. Depending on our actual financial performance results, along with relative TSR performance for the PSUs granted in 2020 and 2021, 0% to 200% of the number of PSUs granted is delivered in shares of our common stock. The following tables provide the payout (as a percentage of target) for maximum, target and threshold performance levels for the 2021 and 2018 PSU awards, respectively. The Compensation Committee sets the performance levels after reviewing our financial strategy, the design of PSU awards at peer group companies and historical EPS growth data for the S&P 500^® companies. At the time of setting the target and determining the payouts at varying levels of performance for these awards, the Compensation Committee believed that achievement of the target for annualized adjusted EPS growth was a challenging goal.

The payout of the 2021 and 2020 PSU awards will be determined as follows. The payouts of PSU awards granted prior to 2020 will be determined with respect to the EPS performance factor only.

Performance and Payout Levels for Our 2018 to 2021 PSU Awards

The adjusted EPS growth measure for our PSU awards is shown in the following table. The three-year target for annualized adjusted EPS growth is 8% for our PSU awards granted in 2018 through 2020. In light of continued uncertainty in the business environment related to the COVID-19 pandemic, for the 2021 PSU award, the Compensation Committee set the three-year target at 7%, which recognizes a 6% growth target for 2021 and 8% for the remaining two years.

Summary of PSU Awards Granted from 2018 through 2020

Despite the impact of the pandemic on our financial performance, the Compensation Committee determined not to adjust or reset the 8% target for three-year annualized adjusted EPS growth applicable to the 2018, 2019 or 2020 PSU awards.

The table below summarizes the three-year performance periods for PSU awards granted from 2018 to 2020, including the payout at 110% of target for our 2018 PSU award based on 8.4% annualized adjusted EPS growth as modified for executive compensation purposes.

The PSU award granted in 2020 also includes a modifier based on the Company’s three-year TSR versus S&P 500^® companies. For 2020, our TSR of 6.8% ranked at the 49^th percentile of S&P 500^® companies, which corresponds to a 0.99x modifier as interpolated within the range of a 0.75x modifier for a 25^th percentile ranking to a 1.25x modifier for a 75^th percentile ranking.

The actual payout for 2019 and 2020 PSU awards will depend on three-year performance, except under certain circumstances that require earlier measurement of results, such as the death of a participant or a change in control of the Company.

The financial performance measures used in the PSU awards are defined in “Definitions of Financial Performance Measures” on page 45.

DEFINITIONS OF FINANCIAL PERFORMANCE MEASURES

The following table defines the financial performance measures used in our executive compensation program.



Used for	Measure	Definition

2020 Annual Bonus Framework—Financial Performance Measure	Company or business net operating income	Net operating income calculated in accordance with GAAP, adjusted for the impact of “noteworthy items” identified in Exhibit A to this proxy statement and further adjusted for the impact of currency exchange rate fluctuations and acquisitions and dispositions.

2020 Annual Bonus Framework—Multiplier for Company Financial Performance	Company earnings per share	Adjusted EPS is defined as GAAP earnings per share, adjusted for the impact of “noteworthy items” identified in Exhibit A to this proxy statement and modified to exclude the impact of: 1. currency exchange rate fluctuations; 2. pension expense; 3. results for Marsh & McLennan Risk Capital Holdings, Ltd. (the legal entity through which the Company owns interests in private equity funds and other investments); and 4. the costs related to the early extinguishment of debt. The year-over-year change is calculated based on adjusted EPS as modified for the above exclusions versus prior-year adjusted EPS without modification for such exclusions.

PSUs granted in 2018 and 2019	Company earnings per share	Same definition as 2020 Annual Bonus Framework—Multiplier for Company Financial Performance, above, but without exclusion for the impact of pension expense; in addition, the exclusion of results for Marsh & McLennan Risk Capital Holdings, Ltd. is based on the variation between actual and budgeted results rather than a full exclusion.

PSUs granted in 2020	Company earnings per share	Same definition as 2020 Annual Bonus Framework—Multiplier for Company Financial Performance, above.

PSUs granted in 2021	Company earnings per share	Same definition as 2020 Annual Bonus Framework—Multiplier for Company Financial Performance, above, but with additional exclusion for the impact of changes in the U.S. federal or U.K. statutory corporate tax rate or the U.S. federal tax rate on foreign earnings earned by foreign subsidiaries.

The performance factor for PSU awards is determined based on three-year adjusted EPS growth using three one-year growth rates (annualized). Each year-over-year change is calculated based on adjusted EPS as modified for the above exclusions versus prior-year adjusted EPS without modification for such exclusions.

PEER GROUP COMPANIES AND SURVEYS

Peer Group for Executive Compensation Purposes

In 2020, the Compensation Committee reviewed the executive compensation data disclosed in the publicly available filings of the companies that comprise our peer group for executive compensation purposes. The peer group is based on business lines, talent pool and company size, as reflected by revenue and market capitalization, and includes insurance, consulting and other business services companies, as listed in the table below. The Compensation Committee reviews the peer group periodically and makes adjustments that it deems are appropriate or necessary, for example, as a result of business combinations and other changes. The Compensation Committee has not made any changes to the peer group since September 2019.



2020 Peer Group for Executive Compensation

*Insurance Brokers*	*Insurance Carriers*	*Consulting and Business Services*

Aon plc	American International Group, Inc.	Automatic Data Processing, Inc.
Willis Towers Watson plc	Chubb Limited	Accenture plc
Arthur J. Gallagher & Co.	The Travelers Companies, Inc.	S&P Global Inc.

Financial Services and General Industry Surveys

The Compensation Committee also reviews executive compensation data drawn from two industry subsets (Financial Services and General Industry) of S&P 500^® companies that participated in an executive compensation survey conducted by an independent compensation consulting firm. Each subset was refined based on revenue and market capitalization. For a list of the companies comprising these subsets, please refer to Exhibit B. The business CEO comparisons were based on subsidiaries or divisions of all companies that participated in the executive compensation survey (instead of only S&P 500^® companies) in order to have a significant sample size for these particular comparisons.

BENEFIT PLANS AND OTHER PROGRAMS

Retirement and Deferred Compensation Plans

We offer retirement and deferred compensation plans, in which all of our senior executives are eligible to participate to maintain a competitive compensation program.

We maintain a defined contribution retirement program in the U.S. consisting of the Supplemental Savings & Investment Plan (“SSIP”), an unfunded nonqualified defined contribution retirement plan that is coordinated with our 401(k) Savings & Investment Plan. Additional information about the SSIP, including individual amounts deferred by our named executive officers, Company matching credits and earnings during 2020, as well as account balances as of the end of 2020, is presented in “Nonqualified Deferred Compensation Table” on page 60. Earnings with respect to all of our nonqualified defined contribution plans are based upon actual market performance, and preferential or above-market earnings are not offered.

We discontinued future service accruals in our U.S. and U.K. defined benefit retirement programs effective December 31, 2016 and August 1, 2014, respectively. The features of our U.S. and U.K. retirement programs, including the present value of the accumulated pension benefits for our named executive officers as of the end of 2020, are presented in further detail in “Defined Benefit Retirement Program” on page 58. We do not have individually-designed defined benefit arrangements for any named executive officer.

Severance Arrangements

Severance payments and benefits for our senior executives are provided under our Senior Executive Severance Pay Plan, which provides for severance payments in the event of an involuntary termination of employment without cause (as defined in the plan) in an amount equal to the sum of the senior executive’s then-current base salary and average annual bonus award over the three prior years, plus an amount equal to a pro-rata bonus for the year of termination.

While compensation decisions regarding our senior executives affect the potential payments under these arrangements, the existence of these severance arrangements did not affect the Compensation Committee’s decisions with respect to other elements of compensation for our named executive officers because these severance arrangements are contingent in nature and may never be triggered.


46		Marsh & McLennan Companies, Inc. Notice of Annual Meeting and 2021 Proxy Statement

EXECUTIVE COMPENSATION (Continued)

The terms of the Senior Executive Severance Pay Plan are discussed more fully in “Termination of Employment” on page 64. The amount of the estimated payments and benefits payable to our named executive officers, assuming a termination of employment as of the last business day of 2020, is presented in “Potential Payments Upon Termination or Change in Control” on page 61.

Change-in-Control Arrangements

Change-in-control payments and benefits are provided to our senior executives through our equity-based compensation plans and the Senior Executive Severance Pay Plan, as applicable. These arrangements are intended to retain our senior executives and provide continuity of management in the event of an actual or potential change in control of the Company. Consistent with this objective, the terms of our equity-based awards contain a “double-trigger” vesting provision, which requires both a change in control of the Company and a subsequent specified termination of employment for vesting to be accelerated. The Senior Executive Severance Pay Plan also includes a “double-trigger” change-in-control provision rather than providing severance payments and benefits solely on the basis of a change in control of the Company. We believe that requiring a “double trigger,” rather than providing severance payments (and accelerated vesting of equity-based awards) solely on the basis of a change in control, is more consistent with the purpose of encouraging the continued employment of our senior executives following a change in control of the Company.

We do not provide any excise tax payments, reimbursements or “gross ups” in connection with a change in control of the Company to any of our senior executives under any plan or arrangement.

The amount of the estimated payments and benefits payable to our named executive officers, assuming a change in control of the Company and subsequent specified termination of employment as of the last business day of 2020, is presented in “Potential Payments Upon Termination or Change in Control” on page 61.

Other Benefits and Perquisites

Our senior executives are eligible to participate in our health and welfare benefit programs on the same basis as our other eligible employees. We also provide certain perquisites and other personal benefits to our senior executives. In general, the perquisites or other personal benefits provided to our senior executives include (i) the cost of financial counseling and certain income tax return preparation and (ii) from time to time, relocation or housing costs associated with hiring a newly recruited or promoted senior executive.

In addition, the Compensation Committee has determined to provide Mr. Glaser access to a car and driver for business and commuting purposes and to corporate aircraft, in which we maintain fractional interests, for business and personal travel. Such personal air travel is limited to an amount not to exceed $130,000 per calendar year as determined based on the aggregate incremental cost of such travel to the Company. The imputed income attributable to Mr. Glaser’s personal use of corporate aircraft and a car and driver was taxable income to Mr. Glaser. The taxes associated with this income were not reimbursed or paid by the Company.

The incremental cost of providing perquisites and other personal benefits during 2020 to our named executive officers is presented in the footnotes to the “All Other Compensation” column of the “2020 Summary Compensation Table” on page 51.

EXECUTIVE COMPENSATION (Continued)

RISK AND REWARD FEATURES OF EXECUTIVE COMPENSATION PROGRAM

The Compensation Committee strives to maintain an appropriate balance between risk and reward in support of our overall business strategy. Our executive compensation principles, policies and practices are designed to encourage an appropriate level of risk-taking but not to encourage our senior executives to take excessive or unnecessary risks. To achieve this balance, we maintain the following policies and practices:



Feature		Description

Balanced Total Compensation Approach		The mix of base salary, annual bonus opportunity and annual LTI awards appropriately balances the shorter-term and longer-term aspects of each senior executive’s responsibilities and performance, without undue emphasis on any single element of compensation.

Performance-Based Annual Bonus Program		Awards to senior executives are made based on both financial performance measures, relating to fiscal year performance, and strategic performance objectives, which may relate to longer-term and qualitative objectives. Each senior executive’s target annual bonus and payout range of 0% to 200% is set forth in his or her employment letter. The Compensation Committee determines the bonus for each of our senior executives. We do not guarantee annual bonuses for our senior executives, except in special situations such as the initial bonus award after a senior executive’s hire if the guarantee is deemed necessary to attract a candidate to join the Company.

Stockholder-Focused LTI Program		Equity-based awards to our senior executives are granted annually on a discretionary basis by the Compensation Committee taking into consideration each individual’s past performance and expected future contributions. Awards made in 2020 were in a combination of stock options and PSU awards to align the financial interests of our senior executives with maximizing our return to stockholders. PSU awards are earned based on our achievement against financial performance objectives and, starting with the 2020 PSU award, the Company’s TSR versus S&P 500^® companies over a three-year performance period, both as determined by the Compensation Committee. All equity-based awards are subject to multi-year vesting requirements or performance periods with complete forfeiture of unvested awards upon a voluntary termination of employment by a senior executive (other than by reason of retirement) or termination of employment for cause. None of our equity-based awards are scheduled to begin vesting until at least one year following their grant. In addition, the terms of our outstanding and unvested equity-based awards contain a “double-trigger” vesting provision in the event of a change in control of the Company. We do not provide any excise tax payments, reimbursements or “gross ups” in connection with a change in control of the Company to any of our senior executives under any plan or arrangement.

Executive Stock Ownership Guidelines		Our senior executives are required to acquire and hold shares or stock units of our common stock with an aggregate value at least equal to a specified multiple of their base salary. Our senior executives may not sell shares acquired in connection with the distribution of stock units or exercise of stock options until and unless the specified multiple of base salary is reached and maintained.

Prohibition Against Speculative Activities, Hedging or Pledging of Company Stock		We prohibit our employees, including our senior executives, and directors from engaging in speculative or hedging activities (including short sales, purchases or sales of puts or calls and trading on a short-term basis) in our common stock. We prohibit our senior executives and directors from pledging our securities as collateral for a loan or for any other purpose.

EXECUTIVE COMPENSATION (Continued)



Feature		Description

Compensation Recovery (“Clawback”) Policies		We may, to the extent permitted by applicable law, cancel or require reimbursement of any annual bonus awards received by a senior executive if and to the extent that: (i) the amount of the award was based on the achievement of specified consolidated, segment or business financial results, and we subsequently restate those financial results; (ii) in the Compensation Committee’s judgment, the senior executive engaged in intentional misconduct that contributed to the need for the restatement; and (iii) the senior executive’s award would have been lower if the financial results in question had been properly reported. In such case, we will seek to recover from the senior executive the amount by which the actual annual bonus award paid for the relevant period exceeded the amount that would have been paid based on the restated financial results. The policy provides that we will not seek to recover compensation paid more than three years prior to the date the applicable restatement is disclosed. Also, our 2011 and 2020 Incentive and Stock Award Plans allow us to “claw back” outstanding or already-settled equity-based awards.

Severance Payments		Severance protections for our senior executives are set at a uniform level equal to his or her base salary and three-year average annual bonus award (a “1x multiple”). In addition, without stockholder approval, we will not enter into a severance agreement with a senior executive that provides for any cash severance payment that exceeds 2.99 times the sum of his or her base salary and three-year average annual bonus award.

In light of the above, and based on management’s annual review and analysis focused on the incentive compensation programs covering our general employee population, we believe our compensation policies and practices do not encourage excessive or inappropriate risk-taking and that the risks arising from our compensation policies and practices for our employees are not reasonably likely to have a material adverse effect on the Company.

STOCK OWNERSHIP GUIDELINES

We maintain stock ownership guidelines for our senior executives that are intended to align the financial interests of our senior executives with our stockholders by requiring them to acquire and maintain a meaningful ownership interest in our common stock. These guidelines are intended to take into account an individual’s needs for portfolio diversification, while maintaining an ownership interest at levels sufficient to assure our stockholders of management’s commitment to long-term value creation. Our senior executives are required, over a five-year period, to acquire and hold shares or stock units of our common stock with an aggregate value at least equal to a specified multiple of their base salary. The current multiples for our named executive officers are as follows:



Named Executive Officer	Ownership Level (as a multiple of base salary)

CEO		6x

Other named executive officers		3x

As of February 28, 2021, all of our named executive officers were in compliance with our stock ownership guidelines.

Additional information concerning our stock ownership guidelines is available on our website under:

mmc.com/about/corporate-governance.html.

HOLDING REQUIREMENT FOR EQUITY-BASED AWARDS

Under our stock ownership guidelines, our senior executives are required to hold shares of our common stock acquired in connection with the distribution of stock units or exercise of stock options (net of any tax withholding and, in the case of stock options, the exercise price) until the required multiple of base salary is reached. In addition, our senior executives may not sell any shares of our common stock, however acquired, unless their ownership interest after such sale is at or above the required multiple of base salary stipulated under our stock ownership guidelines.

EXECUTIVE COMPENSATION (Continued)

TAX AND ACCOUNTING CONSIDERATIONS

Section 162(m) of the Internal Revenue Code generally disallows public companies a federal income tax deduction for compensation in excess of $1 million that is paid to certain former or current senior executives in any taxable year. Given the changes to Section 162(m) made by the Tax Cuts and Jobs Act, the incentive compensation and base salary over $1 million paid to our named executive officers for 2020 generally will not be tax deductible. The Compensation Committee reserves the right to award compensation that is not tax deductible.

We also structure compensation in a manner intended to avoid the incurrence of any additional tax, interest or penalties under Section 409A of the Internal Revenue Code governing the provision of nonqualified deferred compensation to our service providers. We account for stock-based compensation in accordance with FASB ASC Topic 718, which requires us to recognize compensation expense relating to share-based payments (such as stock options, PSU awards and RSU awards) in our financial statements. The recognition of this expense has not caused us to limit or otherwise significantly alter the equity-based compensation element of our executive compensation program. This is because we believe equity-based compensation is a necessary component of a competitive executive compensation program and fulfills important program objectives. The Compensation Committee considers the potential impact of FASB ASC Topic 718 on any proposed change to the equity-based compensation element of our program.

ADDITIONAL CONSIDERATIONS

This Compensation Discussion and Analysis includes statements regarding the use of various performance measures and related target levels in the limited context of our executive compensation program. These target levels are not intended to be statements of management’s expectations of our future financial results or other guidance. Investors should not apply these target levels in any other context.

COMPENSATION COMMITTEE REPORT

The Compensation Committee has reviewed and discussed with management the preceding Compensation Discussion and Analysis, as well as the accompanying compensation tables and related narratives. Based on that review and discussion, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement and incorporated into the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

(1)

Ms. Ferland was appointed President and Chief Executive Officer of Mercer Consulting Group, Inc. on March 1, 2019. Her compensation is shown for 2020 and 2019 only since she was not a named executive officer in 2018. Mr. Hearn’s 2019 compensation is shown as required by SEC rules because he was a named executive officer in our 2019 proxy statement with respect to his 2018 compensation.

(2)

The amounts reported in the “Stock Awards” and “Option Awards” columns represent the grant date fair value of the awards for the years ended December 31, 2020, December 31, 2019 and December 31, 2018, respectively, computed in accordance with FASB ASC Topic 718. The amounts reported in the “Stock Awards” column represent PSU awards for 2020 and PSU and RSU awards for 2019 and 2018. The grant date fair value reported for the 2020 PSU awards is based on performance at the target level and, as calculated in accordance with ASC Topic 718, is determined using a Monte Carlo simulation model since payouts are based in part on a relative total stockholder return (“TSR”) modifier, which is a market condition. As stated in the description of the PSU awards following the “2020 Grants of Plan-Based Awards Table” on page 54, the payout based on maximum performance is 200% of the target level, which, if achieved, would correspond to the values reported in the table below, holding constant the grant date fair value of the Company’s common stock. The assumptions used in calculating the amounts reported for awards granted in 2020 are included in footnote 9 to the Company’s audited financial statements for the fiscal year ended December 31, 2020, included in the Company’s Annual Report on Form 10-K filed with the SEC on February 17, 2021. The assumptions used in calculating the amounts reported for awards granted prior to 2020 are included in the footnote captioned “Stock Benefit Plans” to the Company’s audited financial statements for the relevant fiscal year, included in the Company’s Annual Reports on Form 10-K previously filed with the SEC. The amounts reported in these columns may differ slightly from the corresponding amounts shown in the “2020 Grants of Plan-Based Awards Table” on page 54 due to rounding to the nearest whole dollar as required by SEC rules. In addition, the amounts reported in these columns may differ slightly from the amounts disclosed in the “2020 and 2021 Annual Total Direct Compensation of Named Executive Officers” section on page 31 of the Compensation Discussion and Analysis due to rounding to the nearest whole share.

The amounts reported in the “Non-Equity Incentive Plan Compensation” column represent the amounts received for annual bonus awards, as described in the “Annual Bonus” section on page 35 of the Compensation Discussion and Analysis. The awards earned in respect of 2020 were determined by the Compensation Committee at its meeting on February 22, 2021 and were paid on February 26, 2021.

(4)

The amounts reported in the “Change in Pension Value and Nonqualified Deferred Compensation Earnings” column represent the increase, if any, in the present value of the named executive officers’ benefits (both vested and unvested) under the tax-qualified Marsh & McLennan Companies Retirement Plan, the Company’s Benefit Equalization Plan, the Company’s Supplemental Retirement Plan and the Company’s UK Pension Fund. For 2020, the amount reported for each named executive officer reflects changes in age and service, the interest rate and the mortality assumption projecting longer life expectancies, and any change in base salary. The assumptions used in calculating the amounts reported are included in footnote 8 to the Company’s audited financial statements for the fiscal year ended December 31, 2020, included in the Company’s Annual Report on Form 10-K filed with the SEC on February 17, 2021. The Company’s retirement programs are described in further detail in “Defined Benefit Retirement Program” on page 58. No named executive officer received preferential or above-market earnings on deferred compensation. The Company discontinued future service accruals in the U.S. Retirement Program effective December 31, 2016 and discontinued future service accruals in the UK Pension Fund effective August 1, 2014. Ms. Ferland’s change in pension value has been converted from British pounds into U.S. dollars at the average currency exchange rate for 2020 used by the Company for financial reporting purposes in accordance with U.S. GAAP (£1 = $1.28335769).

DEFINED BENEFIT RETIREMENT PROGRAM

The Company discontinued future service accruals effective December 31, 2016 in the tax-qualified Marsh & McLennan Companies Retirement Plan, the nonqualified Benefit Equalization Plan and the nonqualified Supplemental Retirement Plan (collectively, the “U.S. Retirement Program”). The Benefit Equalization Plan is a restoration plan that provides those participants subject to certain Internal Revenue Code limitations with retirement benefits on a comparable basis to those provided to employees who are not subject to such limitations. The Supplemental Retirement Plan provides for an enhanced benefit for a select group of highly compensated employees. Mr. Glaser and Mr. McGivney participate in the United States defined benefit retirement program. Mr. Doyle, Mr. Hearn and Ms. Ferland are not eligible to participate in the United States defined benefit retirement program because they did not meet the eligibility requirements to join the retirement program prior to December 31, 2016.

For participants who are eligible for these plans, annual benefits payable at age 65 in the form of a single-life annuity are determined generally by the following formula:

•

2.0% of eligible salary for each of the first 25 years of eligible benefit service through December 31, 2016; plus

•

1.6% of eligible salary for each of the next five years of eligible benefit service through December 31, 2016; plus

•

1.0% of eligible salary for each year of eligible benefit service over 30 years through December 31, 2016.

The above sum is reduced by an amount representing a portion of the participant’s estimated Social Security benefit. Participants who are at least age 65 are eligible for normal retirement benefits and participants who have attained five years of vesting service and are at least age 55 are eligible for early retirement benefits. Of the named executive officers, Mr. Glaser is eligible for an early retirement benefit. Benefits under the U.S. Retirement Program vest upon the earliest of (i) a participant’s attainment of five years of vesting service, (ii) attainment of age 65 or (iii) a change in control of the Company. Mr. Glaser and Mr. McGivney currently have a vested benefit under the U.S. Retirement Program.

The present value of the accumulated pension benefits of the named executive officers who participate in these plans as of the end of 2020, as well as other information about each of our defined benefit retirement plans, is reported in the table below. Assumptions used in the calculation of these amounts, other than retirement age, are included in footnote 8 to the Company’s audited financial statements for the fiscal year ended December 31, 2020, included in the Company’s Annual Report on Form 10-K filed with the SEC on February 17, 2021. The assumed retirement age used for purposes of this table is 65 years for all named executives who participate in these plans. Benefits under the tax-qualified Marsh & McLennan Companies Retirement Plan are generally paid as a monthly annuity for the life of the retiree and his or her designated survivor, if the participant has elected to be paid on a joint and survivor basis. The Company’s policy for funding its obligation under the tax-qualified plan is to contribute amounts at least sufficient to meet the funding requirements set forth in applicable law. The Company is not required to, and does not, fund any of its obligations to the named executive officers who participate in these plans under any of its nonqualified defined benefit retirement plans.

UK DEFINED BENEFIT RETIREMENT PROGRAM

The Company discontinued service accruals effective August 1, 2014 in the tax-qualified Marsh & McLennan Companies UK Pension Fund (the “UK Pension Fund”). Ms. Ferland participated in the Mercer Section of the United Kingdom defined benefit retirement program prior to August 1, 2014 based on the standard defined benefit terms available to participants since April 1, 2006.

For those participants who are eligible for the plan, annual benefits are payable at age 65 in the form of a single-life annuity, with an attaching 60% benefit payable to a surviving dependent, and are determined generally by the following formula:

•

1.67% of eligible salary for each year of eligible benefit service through July 31, 2014, with accrued pension in each year subject to a cost of living adjustment based on UK price inflation as measured by the Retail Prices Index, up to a maximum of 5% per annum while the participant remains an employee, unless they opt out. Ms. Ferland opted out on December 31, 2018 and consequently the cost of living adjustment reduced to UK price inflation as measured by the Consumer Prices Index, up to a maximum of 5% per annum for benefits accrued before April 1, 2010 (2.5% per annum for benefits accrued after April 1, 2010).

Participants who are at least age 65 are eligible for normal retirement benefits and participants who have attained three months of vesting service and are at least age 55 are eligible for early retirement benefits, subject to actuarial reduction for early payment. Ms. Ferland is eligible for an early retirement benefit. Benefits under the retirement program vest upon a participant’s attainment of three months of vesting service. Ms. Ferland currently has a vested benefit under the retirement program.

(2)

Assumptions used in the calculation of these amounts, other than retirement age, which has been assumed for purposes of this table to be 65 years for all of the named executive officers, are included in footnote 8 to the Company’s audited financial statements for the fiscal year ended December 31, 2020, included in the Company’s Annual Report on Form 10-K filed with the SEC on February 17, 2021. The U.S. Retirement Program provides a survivor benefit, in the form of a monthly annuity, to a qualifying spouse or domestic partner upon the death of a vested participant. The present value of this survivor benefit in the event of death on December 31, 2020 was $913,967 for Mr. McGivney. The total amounts reported in this column may not equal the sum of amounts reflected due to rounding to the nearest whole dollar as required by SEC rules.

For the UK Pension Fund, the calculation of the pension benefits is based on US GAAP single equivalent financial assumptions and demographic assumptions (excluding pre-retirement mortality) for the fiscal year ended December 31, 2020. The pension provided is in line with the Rules of the Mercer Section of the UK Pension Fund and the member is not entitled to any member specific pension enhancements. The UK Pension Fund provides a survivor benefit payable on the death of the member in retirement. This is 60% of the member’s pension at date of death plus if death occurs within the first 5 years, the balance of pension payments in those 5 years. The present value of this survivor benefit in the event of death on December 31, 2020 was $260,737 for Ms. Ferland. These amounts have been converted from British pounds into U.S. dollars at the average currency exchange rate for 2020 used by the Company for financial reporting purposes in accordance with U.S. GAAP (£1 = $1.28335769).

(3)	Mr. Glaser and Ms Ferland are eligible for an early retirement benefit. Their early retirement benefits are separately quantified in the table included in the “Potential Payments Upon Termination or Change in Control” section on page 61.

EXECUTIVE COMPENSATION (Continued)

NONQUALIFIED DEFERRED COMPENSATION TABLE

The Company maintains the Supplemental Savings & Investment Plan (the “SSIP”), a nonqualified deferred compensation plan that coordinates with the Company’s 401(k) Savings & Investment Plan to give eligible participants the opportunity to defer compensation on a pre-tax basis in addition to what is allowed under the tax-qualified plan.

Under the SSIP, selected participants who have reached any one of the limitations set forth in the Internal Revenue Code under the Company’s 401(k) Savings & Investment Plan may, at their election, defer up to 30% of their base salary and notionally invest this amount in any or all of the plan’s notional investment alternatives. These alternatives consist of a variety of mutual funds and units of the Company’s common stock. Participants in the SSIP may change their investment elections at any time, both as to future deferrals and existing balances; however, once a participant notionally invests an amount in units of the Company’s common stock, that amount cannot be reallocated to any other notional investment.

After a participant completes one year of service with the Company, the Company provides matching credits at the same rate as the Company’s 401(k) Savings & Investment Plan. Effective January 1, 2017, eligible participants who are employed by an eligible participating company and have completed one year of service receive a 4% fixed company credit with respect to their base salary over the Internal Revenue Service limit on compensation that may be considered under the Company’s 401(k) Savings & Investment Plan, whether or not they elect to make employee deferrals to the SSIP.

Participants are not permitted to make withdrawals from their accounts while they are employed by the Company. Participants are generally entitled to payment of their accounts after their employment ends, including upon retirement, death or disability in a lump sum or annual installments over 2 to 15 years.

All of the named executive officers were eligible to participate in the SSIP in 2020.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

The following table sets forth the estimated payments and benefits to be provided to the named executive officers in the event of the specified terminations of employment, including following a change in control of the Company. In accordance with SEC rules, this table assumes that the relevant triggering event occurred on December 31, 2020, the last business day of the last completed fiscal year, and that the market price of the Company’s common stock was the closing stock price as of December 31, 2020 ($117.00 per share), the last trading day of 2020.

The employment letter for each named executive officer provides that he/she will participate in the Company’s Senior Executive Severance Pay Plan. In general, the Senior Executive Severance Pay Plan provides for cash severance in the event of an involuntary termination of employment without “cause” (as described in “Termination of Employment” below) or, within the two-year period following a change in control of the Company, either by the successor entity without cause or by the participant for a termination of employment for “good reason” (as described in “Termination of Employment” below). In addition, each such named executive officer is eligible for specified benefits upon death or “disability” (as described in “Termination of Employment” below).

Cash severance under the Senior Executive Severance Pay Plan is paid in a lump sum equal to:

•

one times annual base salary;

•

one times the average of the annual bonuses paid to the participant for each of the three prior calendar years; and

•

a pro-rata bonus for the year of termination.

The Senior Executive Severance Pay Plan also provides 12 months of outplacement services and continued medical and dental coverage for 12 months at active employee rates. Severance payments and benefits are conditioned on a participant having executed a waiver and release of claims in favor of the Company (including restrictive covenants). The cash severance amounts included in the following table reflect the employment arrangements in effect on December 31, 2020.

The terms and conditions of equity-based awards provide for full or pro-rata vesting in the event of death, disability and specified terminations of employment.

For certain events such as retirement, the values are based on results as determined by the Compensation Committee and 8% EPS growth for the remaining years of the award period for each award. For events in which the vesting of equity-based awards accelerates, such as death, the values are based on performance for abbreviated award periods.

(6)	Total amounts reported in this column may not equal the sum of amounts reflected in the preceding columns due to rounding to the nearest whole dollar as required by SEC rules.

Termination of Employment

Upon any termination of employment, including a termination for “cause” or without “good reason,” a named executive officer will receive any accrued pay and regular post-employment payments and benefits under the terms of the Company’s applicable plans. The amounts reported in the table above do not include payments and benefits that are provided on a nondiscriminatory basis to eligible employees upon termination of employment, including:

•

base salary through the date of termination and accrued but unused vacation time;

•

post-employment group medical benefit continuation at the employee’s cost;

•

welfare benefits provided to eligible U.S. or UK retirees;

•

distributions of defined benefit plan benefits, whether or not tax-qualified (our U.S. and UK defined benefit retirement programs are described in the “Defined Benefit Retirement Program” and “UK Defined Benefit Retirement Program” sections, respectively on page 58);

•

distributions of tax-qualified defined contribution plans and nonqualified deferred compensation plans (the nonqualified deferred compensation plans are described in the “Nonqualified Deferred Compensation Table” section on page 60); and

•

vested benefits.

The Senior Executive Severance Pay Plan defines “cause” as a participant’s: (i) willful failure to substantially perform the duties consistent with his or her position which is not remedied within 10 days after receipt of written notice from the Company specifying such failure; (ii) willful violation of any written Company policy, including, but not limited to, the Company’s Code of Business Conduct & Ethics; (iii) commission at any time of any act or omission that results in a conviction, plea of no contest, plea of nolo contendere or imposition of unadjudicated probation for any felony or crime involving moral turpitude; (iv) unlawful use (including being under the influence) or possession of illegal drugs; (v) gross negligence or willful misconduct which results in, or could reasonably be expected to result in, a material loss to the Company or material damage to the reputation of the Company; or (vi) violation of any statutory or common law duty of loyalty to the Company, including the commission at any time of any act of fraud, embezzlement or material breach of fiduciary duty against the Company.

The Senior Executive Severance Pay Plan defines “good reason” as: (i) a material reduction in the participant’s base salary; (ii) a material reduction in the participant’s annual incentive opportunity (including a material adverse change in the method of calculating the participant’s annual incentive); (iii) a material diminution of the participant’s duties, responsibilities or authority; or (iv) a relocation of more than 50 miles from the participant’s office location in effect immediately prior to the change in control of the Company. This definition of “good reason” only applies during the 24-month period following a change in control of the Company.

The employment letter for each named executive officer defines “permanent disability” as occurring when it is determined (by the Company’s disability carrier for the primary long-term disability plan or program applicable to the named executive officer because of his or her employment with the Company) that the named executive officer is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than 12 months.

Change in Control

As described in the “Change-in-Control Arrangements” section on page 47, the terms of our outstanding and unvested equity-based awards contain a “double-trigger” change-in-control vesting provision, which requires a change in control of the Company followed by a specified termination of employment for accelerated vesting to occur. Under the double-trigger provision, a change in control of the Company by itself would not cause an employee’s equity-based award to vest, so long as the award is assumed or replaced on equivalent terms. In that case, vesting would continue pursuant to the award’s original vesting schedule unless, in addition to the change in control, the employee’s employment terminates without “cause” or for “good reason” during the 24 months following the change in control.


64		Marsh & McLennan Companies, Inc. Notice of Annual Meeting and 2021 Proxy Statement

EXECUTIVE COMPENSATION (Continued)

The change-in-control provisions included in our Senior Executive Severance Pay Plan also require both “double-trigger” events to occur for payments and benefits to be provided.

We do not provide change-in-control excise tax reimbursements to any of our senior executives under any plan or arrangement.

Cash severance payments are not eligible for any tax reimbursement benefit.

We use the same definition of “change in control” in the equity incentive plans and the Senior Executive Severance Pay Plan.

The definitions of “cause” and “good reason” in equity-based awards for the named executive officers are similar to those described above in “Termination of Employment.”

Restrictive Covenants

Each of the named executive officers is subject to nonsolicitation covenants that prohibit the executive from:

•

soliciting any customer or client with respect to a competitive activity; and

•

soliciting or employing any employee for the purpose of causing the employee to terminate employment.

Each of the named executive officers is also subject to noncompetition covenants that prohibit the executive from engaging in a competitive activity.

For Mr. Glaser, the noncompetition and nonsolicitation period ends 24 months after the date of termination of employment. For the other named executive officers, this period ends 12 months after the date of termination of employment.

In addition, at all times prior to and following termination of employment, the named executive officers are subject to a perpetual confidentiality covenant.

AUDIT

ITEM 3 — RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee and the Board believe that the continued retention of Deloitte & Touche to serve as the Company’s independent registered public accounting firm is in the best interests of the Company and its investors based on the Audit Committee’s level of satisfaction with the quality of services provided by Deloitte & Touche and consideration of factors described below.

Appointment

The Audit Committee is directly responsible for the appointment, compensation and oversight of the independent registered public accounting firm retained to audit the Company’s financial statements. The Audit Committee has appointed Deloitte & Touche LLP as the Company’s independent registered public accounting firm for the 2021 fiscal year, subject to stockholder ratification. Deloitte & Touche was first retained as the independent registered accounting firm of the Company in 1989.

Review and Approval: Compensation, Leadership, Composition and Organization

The Audit Committee is responsible for reviewing and approving the compensation of Deloitte & Touche in connection with the annual appointment process. As part of its regular process, the Audit Committee annually reviews and approves the leadership, composition and organization of the external audit team. The Audit Committee also periodically considers the rotation of the independent external audit firm and whether to commence an audit tender process, considering such factors as the tenure, fees, independence and capabilities of the external auditor. Further, in conjunction with the mandated rotation of the independent registered public accounting firm’s lead audit partner, the Audit Committee and its chairman are directly involved in the review and approval of Deloitte & Touche’s lead audit partner.

2021 Audit and Other Services

Deloitte & Touche will audit our consolidated financial statements for fiscal year 2021 and perform other services. Deloitte & Touche acted as the Company’s independent registered public accounting firm for the year ended December 31, 2020. A Deloitte & Touche representative will be present at the 2021 annual meeting of stockholders and will have an opportunity to make a statement and to answer your questions.

Good Corporate Practice

Although ratification is not required by the Company’s bylaws or otherwise, the Board is submitting this proposal as a matter of good corporate practice. If the selection is not ratified, the Audit Committee will consider whether it is appropriate to select another independent auditor. Even if the selection is ratified, the Audit Committee may select a different auditor at any time during the year if it determines that this would be in the best interests of the Company and its stockholders.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THIS PROPOSAL.

Audit Committee Pre-Approval Policy

The Audit Committee has adopted a policy regarding pre-approval of audit and non-audit services provided by Deloitte & Touche to the Company and its subsidiaries. The policy provides the guidelines necessary to adhere to the Company’s commitment to auditor independence and compliance with relevant rules and regulations relating to auditor independence. The policy contains a list of prohibited non-audit services, and sets forth four categories of permitted services (Audit, Audit-Related, Tax and Other), listing the types of permitted services in each category. All of the permitted services require pre-approval by the Audit Committee. In lieu of Audit Committee pre-approval on an engagement-by-engagement basis, each category of permitted services, with reasonable detail as to the types of services contemplated, is pre-approved as part of the annual services performed by Deloitte as approved by the Audit Committee. Permitted services not contemplated during the budget process must be presented to the Audit Committee for approval prior to the commencement of the relevant engagement. The Audit Committee chair, or, if he is not available, any other member of the Committee, may grant approval for any such engagement if approval is required prior to the next scheduled meeting of the Committee. Any such approvals are reported to the Audit Committee at its next meeting. At least twice a year, the Audit Committee is presented with a report showing amounts billed by the independent registered public accounting firm compared to the budget approvals for each of the categories of permitted services. The Committee reviews the suitability of the pre-approval policy at least annually.

AUDIT COMMITTEE REPORT

The Audit Committee of the Board of Directors is comprised of the five directors named below. Each member of the Committee is independent as required by the Company, the listing standards of the NYSE and the SEC’s audit committee independence rules. The primary function of the Audit Committee is to assist the Board of Directors in its oversight responsibilities with respect to the integrity of the Company’s financial statements; the qualifications, independence and performance of the Company’s independent auditors; the performance of the Company’s internal audit function; and compliance by the Company with legal and regulatory requirements. The Committee operates pursuant to a charter approved by the Board of Directors.

Management is responsible for the Company’s financial statements, the overall reporting process and the system of internal control, including internal control over financial reporting. Deloitte & Touche LLP, our independent registered public accounting firm, is responsible for conducting annual audits and quarterly reviews of the Company’s financial

AUDIT (Continued)

statements and expressing an opinion as to the conformity of the annual financial statements with generally accepted accounting principles in the United States and expressing an opinion on our internal control over financial reporting as of the end of our fiscal year.

In performing their oversight responsibility, members of the Audit Committee rely without independent verification on the information provided to them and on the representations made by management and Deloitte & Touche. The members of the Committee are not professionally engaged in the practice of auditing or accounting and are not experts in the fields of accounting or auditing, including in respect of auditor independence.

During 2020, the Audit Committee executed its oversight function through a series of meetings and teleconferences with management and Deloitte & Touche. The Audit Committee also reviewed and discussed with management and Deloitte & Touche the Company’s audited financial statements as of and for the year ended December 31, 2020, as well as matters related to internal control over financial reporting and the processes that support the Company’s reporting of financial results. The Committee also discussed with Deloitte & Touche the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. The Committee has received the written disclosures and the letter from Deloitte & Touche required by applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee concerning independence, has considered whether the provision of other non-audit services by Deloitte & Touche to the Company is compatible with maintaining Deloitte & Touche’s independence and has discussed with Deloitte & Touche that firm’s independence.

Based upon the review and discussions described in this report, the Committee recommended to the Board, and the Board approved, that the audited financial statements and management’s annual report on internal control over financial reporting be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC. The Committee has also selected Deloitte & Touche as the Company’s independent registered public accounting firm for 2021. The Board of Directors concurred with that selection and has recommended this selection to the Company’s stockholders for ratification.

CEO PAY RATIO

The ratio of the annual total compensation for our CEO compared to the annual total compensation of our median employee for fiscal year 2020 is 290, as calculated in accordance with Item 402(u) of Regulation S-K. We believe this ratio to be a reasonable estimate, based upon the assumptions and adjustments described below.

The ratio for fiscal year 2020 is based on the annual total compensation of the Company’s median employee (excluding the CEO) and the CEO (as disclosed in the 2020 Summary Compensation Table in this proxy statement), as follows:

We identified the median employee based on total cash compensation, including base salary for 2020 and cash incentive compensation for 2019, for all individuals, excluding our CEO, who were employed by the Company (including our consolidated subsidiaries) on the median employee determination date (December 31, 2020).

Our total number of employees on the median employee determination date, including U.S. and non-U.S. employees, was approximately 78,500.

We annualized the base salary of regular full-time and part-time employees hired in 2020 and of employees on a leave of absence. We did not annualize the base salary of temporary employees.

For employees paid other than in U.S. dollars, we converted their compensation to U.S. dollars using the Company’s budgeted currency exchange rates for fiscal year 2020.

After identifying the median employee, we calculated annual total compensation for that employee for fiscal year 2020 using the same methodology used to calculate the amount reported for our named executive officers in the “Total” column of the 2020 Summary Compensation Table.

TRANSACTIONS WITH MANAGEMENT AND OTHERS

Peter C. Hearn is President and Chief Executive Officer of Guy Carpenter & Company and Vice Chair, Marsh McLennan. David A.

Who Can Vote on the Matters Being Decided at the Annual Meeting?

With respect to each matter properly brought before the meeting, each stockholder who held shares as of the close of business on March 22, 2021, which we refer to as the record date, is entitled to one vote, at the annual meeting or by proxy, for each share of common stock held as of that date. As of the record date, there were outstanding 509,481,765 shares of Marsh & McLennan Companies common stock entitled to vote.

Stockholders of Record

If, as of the close of business on the record date, your shares were registered directly in your name with our transfer agent, Equiniti Trust Company, you are a stockholder of record. As a stockholder of record, you may vote during the meeting or by proxy. The Company is incorporated in Delaware, and in accordance with Delaware law, a list of the Company’s common stockholders of record as of the record date will be available for inspection for at least ten days prior to the annual meeting by contacting Investor Relations by telephone at (212) 345-1227 or by e-mail mmc.investor.relations@mmc.com. The list will also be available during the virtual annual meeting at www.virtualshareholdermeeting.com/MMC2021.

Beneficial (“Street Name”) Stockholders

If, as of the close of business on the record date, your shares were not held directly in your name but rather were held in an account at a brokerage firm, bank or similar intermediary organization, then you are the beneficial holder of shares held in “street name.” The intermediary is considered to be the stockholder of record for purposes of voting during the annual meeting. As a beneficial owner, you have the right to direct the intermediary how to vote the shares held in your account.

How do I Vote?

Whether you hold shares as a stockholder of record or beneficial owner, you may direct how your shares are voted without attending the annual meeting. Even if you plan to attend the annual meeting, we encourage you to vote in advance of the meeting. If you are a stockholder of record, you may vote by submitting a proxy in accordance with the instructions included in your Notice or on your proxy card. If you are a beneficial owner holding shares in street name, you may vote by submitting voting instructions to your broker, bank, trustee or other intermediary in accordance with the voting instruction form provided to you. Executors, administrators, trustees, guardians, attorneys and other representatives voting on behalf of a stockholder should indicate the capacity in which they are voting and corporations should vote by an authorized officer whose title should be indicated.

You May Vote in the Following Manner:

By Telephone or the Internet

You may vote your shares via telephone or the Internet as instructed in the Notice or the proxy card, depending on how you received the proxy materials. The telephone and Internet procedures are designed to authenticate a stockholder’s identity, to allow stockholders to vote their shares and to confirm that their instructions have been properly recorded.

By Mail

Stockholders who receive hard copies of the proxy materials may choose to vote by mail and, if you so choose, should complete, sign and date your proxy card or voting instruction card and mail it in the pre-addressed envelope included with the proxy materials. Note that, if you are a stockholder of record and you sign and return a proxy, but do not

specify how to vote, your shares will be voted by the proxies in accordance with the Board’s recommendations, which will be in favor of our director nominees (Item 1); to approve, by nonbinding vote, the compensation of our named executive officers (Item 2); and in favor of the ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm (Item 3).

Can I Vote My Shares at the Virtual Annual Meeting?

Yes. However, even if you plan to attend the meeting, we recommend that you vote in advance of the meeting. If you vote in advance and then attend the meeting, you can always change your vote at the meeting.

Stockholders may vote during the virtual annual meeting by logging into the meeting website and following the instructions on the website. Stockholders will need the 16-digit control number found on their proxy card, voting instruction form or notice they previously received to vote during the meeting.

Can I Change My Vote?

Yes. Stockholders of record may revoke their proxy before it is voted at the annual meeting by (i) submitting a new proxy with a later date, (ii) voting at the annual meeting or (iii) sending written notification of revocation addressed to: Marsh & McLennan Companies, Inc., Attn: Katherine J. Brennan—Corporate Secretary, 1166 Avenue of the Americas, New York, New York 10036-2774

If you hold your shares in street name, you may change your vote by submitting new voting instructions to your broker or other intermediary, following the instructions they provided, before the annual meeting or by voting during the annual meeting.

What Should I do to Attend the Annual Meeting?

On the day of the annual meeting, visit www.virtualshareholdermeeting.com/MMC2021 to attend the annual meeting. Stockholders will need the 16-digit control number found on their proxy card, voting instruction form or notice they previously received to ask questions or vote.

We encourage you to log in to the website and access the webcast early, beginning approximately 15 minutes before the annual meeting start time. If you experience technical difficulties, please contact the technical support telephone number posted on the virtual stockholder meeting log in page.

The virtual meeting platform is supported across various Internet browsers and devices (desktops, laptops, tablets and cell phones) running the most updated version of applicable software and plugins. You should check that you have a strong Internet connection wherever you intend to attend the meeting.

Whether you hold shares as a stockholder of record or are a beneficial owner, we urge you to vote in advance by Internet, telephone or mail so that your vote will be counted in the event you later decide not to attend the annual meeting.

What Should I Do to Ask a Question at the Annual Meeting?

Prior to meeting

Stockholders may submit questions in advance of the meeting by visiting proxyvote.com. Stockholders will need the 16-digit control number found on their proxy card, voting instruction form or notice they previously received to ask questions.

During the meeting

On the day of the meeting, stockholders must visit virtualshareholdermeeting.com/MMC2021 to ask questions during the meeting. Stockholders will need the 16-digit control number found on their proxy card, voting instruction form or notice they previously received to ask questions.

What are the Requirements to Conduct Business at the Annual Meeting?

In order to carry on the business of the annual meeting, we must have a quorum. This means at least a majority of the outstanding shares eligible to vote must be present or represented by proxy at the annual meeting. Both abstentions and broker nonvotes (described below) are counted for the purpose of determining the presence of a quorum.


		Marsh & McLennan Companies, Inc. Notice of Annual Meeting and 2021 Proxy Statement			77

ADDITIONAL INFORMATION (Continued)

What are the Voting Requirements to Elect Directors and to Approve the Other Proposals Discussed in the Proxy Statement?

The voting standards applicable to the annual meeting are as follows:

Election of Directors

The Company’s bylaws provide that in an uncontested election, a nominee will be elected if the number of votes cast “for” the nominee’s election exceeds the number of votes cast “against” the nominee’s election. Abstentions will not be included in the total number of votes cast and therefore will have no effect on the election’s outcome. The election of directors is not considered a “routine” matter and thus brokers do not have discretionary authority to vote in the election of directors if they did not receive instructions from a beneficial owner. (See “Significance of Broker Nonvotes” below.)

Our Governance Guidelines address the procedures to be followed if an incumbent director standing for reelection in an uncontested election fails to receive a majority of the votes cast. See “Director Election Voting Standard” on page 8.

Vote Required for Other Proposals



Proposal		Vote Required
Item 2—Advisory (nonbinding) vote to approve named executive officer compensation		Majority of the shares entitled to vote and present or represented by proxy
Item 3—Ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm

In accordance with Delaware law, abstentions will be treated as present and entitled to vote for purposes of voting on these items, while broker nonvotes (described below) will not. Abstentions have the effect of a vote “against” each of the proposals.

Significance of “Broker Nonvotes”

The rules of the NYSE provide that, when a matter to be voted on at an annual meeting is “non-routine,” a broker holding shares of record on behalf of a client may vote those shares only if the broker has received voting instructions from the client. The broker may submit a proxy on any routine matter for which instructions were required but not provided, but when the broker refrains from voting on non-routine matters, a “broker nonvote” occurs. Shares subject to a broker nonvote are not counted as present or represented with respect to those matters, but are counted as present and represented for purposes of determining the presence of a quorum at the annual meeting. Under the rules of the NYSE, the election of directors (Item 1), and the nonbinding vote to approve the compensation of our named executive officers (Item 2) are considered non-routine.

Could Additional Matters be Decided at the Annual Meeting?

As of the date of this proxy statement, we do not know of any matters not described in this proxy statement that will be presented at the meeting. However, if any other matter shall properly come before the meeting, the persons named in the proxy will use their discretion to vote on such matter on behalf of shares for which proxies were submitted.

Who Conducts the Annual Meeting?

The independent chairman of the Board of Directors acts as chairman of the annual meeting and has the authority to conduct the annual meeting so that the business of the meeting is carried out in an orderly and timely manner. In doing so, the chairman has the discretion to establish reasonable rules for comments and questions during the meeting.

Who will Count the Votes at the Annual Meeting?

One or more representatives of Broadridge Financial Solutions, Inc. will tabulate the votes and act as independent inspectors of election.

How May I Obtain Electronic Delivery of Proxy Materials in the Future?

Most stockholders may elect to receive future proxy statements and annual reports electronically via e-mail or the Internet instead of receiving paper copies in the mail. If you are a stockholder of record, you may choose this electronic delivery option by following the instructions provided when you vote over the Internet. Active employees of the Company who hold Marsh & McLennan Companies common stock in certain employee benefit plan accounts or are stockholders of record generally receive their proxy materials by electronic delivery to their business e-mail accounts.


78		Marsh & McLennan Companies, Inc. Notice of Annual Meeting and 2021 Proxy Statement

ADDITIONAL INFORMATION (Continued)

If you are a beneficial owner who holds shares in street name, it is likely that you will have the option to choose future electronic delivery of proxy materials when you vote over the Internet. Otherwise, please contact your broker or other intermediary holder of record for information regarding electronic delivery of proxy materials.

Stockholders who receive their proxy materials electronically receive an e-mail message with instructions on how to access the proxy statement and annual report and vote. If you have chosen to receive proxy materials electronically, your choice will remain in effect until you revoke it.

How are Materials Provided to Stockholders Sharing the Same Address?

In order to reduce paper and postage costs, we have adopted a procedure approved by the SEC called “householding.” Under this procedure, stockholders of record or who hold shares in certain employee benefit plan accounts and who share the same last name and reside at the same mailing address will receive one Notice or one set of proxy materials (if they have elected to receive hard copies of the proxy materials), unless one of the stockholders at that address has notified us that they wish to receive individual copies.

Stockholders who participate in householding continue to receive separate control numbers for voting and, in the case of those who receive hard copies of the proxy materials, separate proxy cards. Householding does not in any way affect dividend check mailings.

If you are a stockholder of record or hold our common stock in an employee benefit plan account and currently are subject to householding, but prefer to receive separate copies of proxy materials and other stockholder communications from the Company, you may revoke your consent to householding at any time by calling Broadridge Financial Solutions, Inc. toll-free at 1-800-542-1061 or by writing to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717.

Beneficial Stockholders

A number of brokerages and other institutional holders of record have implemented householding. If you are a beneficial owner who holds shares in street name, please contact your broker or other intermediary holder of record to request information about householding.

How May I Obtain Another Set of Proxy Materials?

This proxy statement and our 2020 Annual Report can be viewed on (and printed from) our website at proxy.mmc.com. If you wish to receive a separate paper copy of our annual report or proxy statement, you may telephone our office of Investor Relations at (212) 345-1227, email mmc.investor.relations@mmc.com, or write to: Marsh & McLennan Companies, Inc., Attn: Investor Relations, 1166 Avenue of the Americas, New York, New York 10036-2774

Who will Bear the Cost of this Proxy Solicitation?

We are providing these proxy materials in connection with the solicitation made by the Company’s Board of Directors of proxies to be voted at our annual meeting. We pay the expenses of preparing and distributing the proxy materials and soliciting proxies. We also reimburse brokers and other institutional record holders for their expenses in forwarding these materials to, and obtaining voting instructions from, beneficial owners of the Company’s common stock.

In addition to the distribution of this proxy statement and instructions for voting at the annual meeting, proxies may be solicited personally, electronically or by telephone by our directors, officers and other colleagues at no additional compensation. We have retained Georgeson LLC as our agent to assist in the proxy solicitation at a fee of approximately $12,650, plus expenses.

SUBMISSION OF STOCKHOLDER PROPOSALS AND OTHER ITEMS OF BUSINESS FOR 2022 ANNUAL MEETING

Stockholder Proposals and Director Nominations for Inclusion in the Proxy Statement

Pursuant to Rule 14a-8, if a stockholder wants the Company to consider a proposal for inclusion in our proxy materials for presentation at our 2022 annual meeting of stockholders, the proposal must be received by us at our principal executive offices at 1166 Avenue of the Americas, New York, NY 10036-2774, not later than December 1, 2021.

Our bylaws permit a stockholder, or a group of up to 20 stockholders, owning 3% or more of the Company’s outstanding common stock continuously for at least three years to nominate and include in the Company’s proxy materials directors constituting up to the greater of two or 20% of board seats, if the stockholder(s) and the nominee(s) meet the requirements in our bylaws. Notice of director nominations submitted under these proxy access bylaw provisions must be received no earlier than November 1, 2021 and no later than December 1, 2021. Director nominations submitted pursuant to the proxy access provisions of our bylaws must comply with all of the requirements of our bylaws.

Other Stockholder Proposals or Director Nominations

Our bylaws set forth certain requirements that a stockholder must follow if the stockholder wants to nominate a person for election as director or propose an item of business (“other stockholder business”) at an annual meeting of stockholders that is not included in our proxy statement. To properly bring the nomination or other stockholder business before an annual meeting, the proponent must be a stockholder of record both at the time the relevant notice of proposal is submitted and at the time of the annual meeting and be entitled to vote at the annual meeting, and comply with certain notice procedures. In the case of other stockholder business, the business must otherwise be a proper matter for stockholder action in accordance with law, the Company’s Certificate of Incorporation and the Company’s bylaws. The notice of proposal (nominating a person for election as director or proposing other stockholder business) also must comply with certain procedures regarding timeliness and form. The notice must be delivered not earlier than 5:00 p.m. Eastern Time on January 20, 2022, and not later than 5:00 p.m. Eastern Time on February 19, 2022. The notice must be delivered to Katherine J.

RECONCILIATION NON-GAAP MEASURES – ACTUAL AS REPORTED TWELVE MONTHS ENDED DECEMBER 31

(Millions) (Unaudited)

Overview

The Company reports its financial results in accordance with accounting principles generally accepted in the United States (referred to in this release as “GAAP” or “reported” results). The Company also refers to and presents below certain additional non-GAAP financial measures, within the meaning of Regulation G under the Securities Exchange Act of 1934. These measures are: adjusted operating income (loss), adjusted operating margin, adjusted income, net of tax and adjusted earnings per share (EPS). The Company has included reconciliations of these non-GAAP financial measures to the most directly comparable financial measure calculated in accordance with GAAP in the following tables.

The Company believes these non-GAAP financial measures provide useful supplemental information that enables investors to better compare the Company’s performance across periods. Management also uses these measures internally to assess the operating performance of its businesses, to assess performance for employee compensation purposes and to decide how to allocate resources. However, investors should not consider these non-GAAP measures in isolation from, or as a substitute for, the financial information that the Company reports in accordance with GAAP. The Company’s non-GAAP measures include adjustments that reflect how management views our businesses, and may differ from similarly titled non-GAAP measures presented by other companies.

Adjusted Operating Income (Loss) and Adjusted Operating Margin

Adjusted operating income (loss) is calculated by excluding the impact of certain noteworthy items from the Company’s GAAP operating income or (loss). The following tables identify these noteworthy items and reconcile adjusted operating income (loss) to GAAP operating income or loss, on a consolidated and segment basis, for the twelve months ended December 31, 2020 and 2019. The following tables also present adjusted operating margin. In 2019, the Company changed its methodology for calculating adjusted operating margin due to the significant amount of identified intangible asset amortization related to the acquisition of JLT on April 1, 2019. For the twelve months ended December 31, 2020 and 2019, adjusted operating margin is calculated by dividing the sum of adjusted operating income plus identified intangible asset amortization by consolidated or segment adjusted revenue.

This loss is removed from GAAP revenue in the calculation of adjusted operating income.

(f)

Consulting in 2020 includes a contingent gain adjustment from Mercer’s U.S. large market health and defined benefit administration business sold in 2019. 2019 reflects the loss on the sale of a U.S. Specialty business at Marsh and a gain on the sale of Mercer’s stand-alone U.S. large market health and defined benefit administration business, which are both included in revenue.

Adjusted income, net of tax is calculated as the Company’s GAAP income from continuing operations, adjusted to reflect the after tax impact of the operating income adjustments set forth in the preceding tables and investments gains or losses related to the impact of mark-to-market adjustments on certain equity securities.
