Proxy Statement Highlights

2021 Company Highlights

Willis Towers Watson Public Limited Company was formed on January 4, 2016 upon completion of the merger (the “Merger”) between Willis Group Holdings Public Limited Company (“legacy Willis Group”) and Towers Watson & Co. (“legacy Towers Watson”). We are a leading global advisory, broking and solutions company that helps clients around the world turn risk into a path for growth. We have more than 44,000 employees and service clients in more than 140 countries and territories. In this Proxy Statement, we refer to Willis Towers Watson as the “Company,” “WTW,” “we” and “our.”

2021 served as a transformative year for Willis Towers Watson Public Limited Company. Solid Company performance throughout the year demonstrated the resilience of WTW’s colleagues and a diversified portfolio of products and services, amid challenges caused by the COVID-19 pandemic and a shift in WTW’s strategy as an independent company. Despite these unprecedented circumstances, the Company continued to serve our clients, protect our colleagues and safeguard our business fundamentals.

With the COVID-19 pandemic, the Company continued its comprehensive set of global processes to stabilize business operations while providing high quality service to clients. This included ongoing global business continuity and incident management efforts to restrict travel, limit office access and enhance our global workforce to a work-from-home protocol with split team operations for our essential workers. The Company regularly considered the impact of the pandemic on our business and stress tested the rigor of our business resilience, continuity plans, forecasting and liquidity management. Throughout 2021, the Company took decisive measures to reinforce working capital discipline and reduce discretionary spending.

From March 2020 through July 2021, the Board of Directors (the “Board”) and leadership drove the Company towards the closing of the business combination with Aon plc (“Aon”), which would have been an all-stock transaction with a combined equity value of approximately $80 billion. One of the goals of the combination was to accelerate elements of the Company’s pre-existing strategy. At the same time as leadership was driving towards the closing of the transaction, they were also managing the day-to-day business of the Company. When the proposed Aon combination was terminated in July, after almost 18 months of integration planning and closing preparations and after a period of substantial uncertainty, the Board and leadership quickly shifted their attention to supporting the Company on an independent path. With the combination no longer feasible, the Company took decisive actions to accelerate its standalone strategy and aggressive steps to retain colleagues and recruit new talent, to enhance its ability to serve clients and to create value for stakeholders. In particular, the Company quickly announced a CEO successor, hired a new CFO and took significant steps to refresh the Board; transformed its senior management structure through the creation of a new Global Leadership Team and simplified the Company’s organizational structure; sold its treaty reinsurance business, generating several billion dollars of capital for focused investments and share repurchases; and created and launched an ambitious strategic plan to grow, simplify and transform with plans to refresh the WTW brand.

These actions, combined with the commitment of our leaders and colleagues, helped WTW deliver solid financial results in 2021 and position the Company for future years.

Proxy Statement Proposal Highlights

The below provides an overview of each of the proposals being presented at the Company’s 2022 Annual General Meeting of Shareholders. For more complete information, please review the respective proposals in their entirety.

Table of Contents

Proposal No. 1: Elect Directors

Our Board is responsible for overseeing our global business in a manner consistent with its fiduciary duties. This oversight requires highly skilled individuals with various qualities, attributes and professional experience. The Corporate Governance and Nominating Committee (the “Governance Committee”) continuously assesses the Board’s size and composition to determine if it is effective and represents the long-term interests of shareholders.

As discussed further below, the Governance Committee believes that the slate of nominees as a whole reflects the collective knowledge, integrity, reputation and leadership abilities, and the diversity of skills and experience and attributes that are appropriate for the Company’s governance. At the Governance Committee’s recommendation, the Board has nominated the individual nominees listed in this Proposal No. 1 to serve until the next Annual General Meeting of Shareholders unless they are removed or resign before that meeting.

The Board unanimously recommends a vote “FOR” the election of each of the directors.

Required Vote

Our directors are elected by way of separate resolutions, each of which requires the affirmative vote of a majority of the votes cast by shareholders at the Annual General Meeting of Shareholders, and hold office until the next Annual General Meeting of Shareholders unless they are removed or resign before that meeting. Any nominee for director who does not receive a majority of the votes cast is not elected to the Board.

Diversity

We are committed to maintaining diversity on our Board as provided in our Corporate Governance Guidelines. Both the Board and the Governance Committee believe that Board diversity is important to ensure a balanced Board with a rounded perspective. Diversity is broadly interpreted by the Board to include viewpoints, background, experience, industry knowledge and geography, as well as more traditional characteristics of diversity, such as race and gender. We have significantly refreshed our Board since our last annual general meeting of shareholders with four new independent directors joining the Board since January 1, 2022 and a fifth nominated for election, creating a further diverse Board (as self-identified). We believe that our commitment to diversity is demonstrated by our Board composition, which reflects diversity of gender, ethnicity and nationality, and varied backgrounds and skill sets, including as follows (assuming all nominated directors are elected and have joined the Board):

Proposal No. 1: Elect Directors (continued)

The table below provides additional diversity information about our Board as of the 2022 Annual General Meeting of Shareholders (assuming all nominees are elected), in the categories listed below, each of which has the meaning as it is used in Nasdaq Listing Rule 5605(f).

Board Evaluation Process

The Governance Committee considers the Board’s size, composition and effectiveness throughout the year. This includes a constructive annual evaluation process, which the Board recognizes is an essential component of good corporate governance and Board effectiveness.

The Governance Committee oversees the process and format of the evaluations of the Board and its Committees. As the process is dynamic, the format may change from year-to-year at the discretion of the Governance Committee to ensure that honest and actionable feedback is solicited and obtained from the directors. As the Board manages evolving expectations for how boards should meet their oversight duties and assess their own performance, the format of the evaluations may vary from written questionnaires analyzed by the office of the Corporate Secretary to interviews, including from time to time by a third-party facilitator.

Typically, the annual evaluation involves a multi-step process, as set forth below, that aims to generate robust comments and discussion at all levels of the Board and each Committee, with topics ranging from Board composition to processes to materials:

Proposal No. 1: Elect Directors (continued)

The evaluation process has resulted in enhancements or changes to, among other things, meeting materials, meeting topics, meeting structure, committee structure and composition and the evaluation process itself.

Board and CEO Succession

As previously announced, the Company had been engaging in a thorough, multi-year succession planning process prior to announcing the transaction with Aon in March 2020, including planning with respect to CEO succession and with respect to the composition of the Board. In 2021, including following the termination of the proposed transaction with Aon, the Board continued its work on succession planning, making announcements with respect both the transition to a new CEO and changes to Board composition.

CEO Succession

Following a succession planning process, including input from a third-party consultant to assess the experience and attributes of potential internal and external candidates, the Board appointed Mr. Hess as CEO, effective January 1, 2022. Mr. Hess served as a President from August 16, 2021 until his predecessor as CEO and a Board member, John Haley, retired at the end of 2021, as previously scheduled in his contract. For further information on Mr. Hess’s experience, see his biographical information below.

Board Succession

Following a succession planning process, including input from a third-party consulting firm and investors, the Board appointed four new independent directors, each of whom is nominated for election at the 2022 Annual General Meeting of Shareholders along with a fifth new independent director. In particular, concurrent with the transition to Mr. Hess as the new CEO, Dame Inga Beale, Mr. Michael Hammond and Ms. Michelle Swanback joined the Board, effective January 1, 2022. Additionally, Ms. Fumbi Chima joined the Board, effective April 1, 2022, and Mr. Paul Reilly is nominated for election to the Board, effective October 1, 2022. For further information on the new directors’ experience, see their biographical information below.

In order to facilitate the director transition process and spend time on other commitments, Mr. Jaymin Patel stepped down from the Board on January 1, 2022, at which time three of the new, independent directors and the Company’s new CEO joined the Board. Further, Mr. Victor Ganzi, Ms. Anna Catalano, Ms. Wendy Lane and Mr. Wilhelm Zeller decided not to run for re-election to the Board at the 2022 Annual General Meeting of Shareholders. The Board appointed Mr. Paul Thomas to serve as the next Non-Executive Chair of the Board, succeeding Mr. Ganzi at the conclusion of his term at the 2022 Annual General Meeting of Shareholders. If re-elected to the Board, Mr. Thomas’s term as Chair will commence at the conclusion of the 2022 Annual General Meeting of Shareholders and will continue until the conclusion of the 2023 Annual General Meeting of Shareholders.

Proposal No. 1: Elect Directors (continued)

As a result of the foregoing, immediately following the 2022 Annual General Meeting of Shareholders (assuming all director nominees are elected), the Board will be composed of eight directors, four of whom will be new to the Board as of 2022. In addition, as of October 1, 2022 (assuming all director nominees are elected), the Board will be composed of nine directors, five of whom will be new to the Board as of 2022, respectively. Following the 2022 Annual General Meeting of Shareholders the Board will also have a new Chair.

Director Qualifications

When recommending an individual for new or continued membership on the Board, the Governance Committee considers each nominee’s individual qualifications in light of the overall mix of attributes represented on the Board, and the Company’s current and future needs. In its assessment of each nominee, the Governance Committee considers, at a minimum, the person’s integrity, experience, reputation, judgment, independence, maturity, skills and personality, commitment and, for current directors, his or her performance on the Board and its Committees.

Additionally, the Governance Committee:

In assessing whether directors and director nominees have sufficient time to devote to Board duties and responsibilities, the Governance Committee considers, among other things, the number of other public company boards of directors on which a director serves as well as other commitments. The Company’s Corporate Governance Guidelines restrict the number of public company boards on which our directors may serve. None of the Company’s directors are considered “overboarded” under the Guidelines. The Board believes that each director has demonstrated the ability to devote sufficient time and attention to Board and Committee duties, and otherwise fulfill the responsibilities required of directors.

Proposal No. 1: Elect Directors (continued)

The Board evaluates each director nominee and each director’s continued service on the Board, based on his or her own merits, knowledge, experience and attributes. For this reason, the Board has not adopted a mandatory retirement age as it believes that doing so might hinder the selection or continued service of a director who would serve as an asset to the Board.

We have highlighted below some key qualifications, attributes, skills and experiences of each director nominee at the Annual General Meeting that were considered by the Governance Committee. The absence of a particular bullet point does not mean that a director does not possess other important qualifications or skills.

Corporate Governance

The Company believes good governance is critical to achieving long-term shareholder value. We are committed to governance policies and practices that serve the long-term interests of the Company and its shareholders.

Corporate Governance Highlights

Corporate Governance (continued)

Board and Committee Member Independence

Based on the recommendation of the Governance Committee, the Board has determined that, with the exception of Mr. Hess, (i) each of the current directors and director nominees and (ii) each of the Board Committee members is independent under the relevant SEC rules, NASDAQ listing standards and the Board’s Director Independence Standards. The Board’s Director Independence Standards are part of the Company’s Corporate Governance Guidelines, which were adopted by the Board and which comply with the requirements of NASDAQ listing standards.

As discussed above, each director has significant experience and affiliations with other organizations that bring relevant expertise to the oversight of the Company. In evaluating the independence of each director, the Governance Committee considered that, in the ordinary course of business, the Company provides services (such as insurance broking or consulting services) to, receives services from, or provides charitable donations to, certain organizations affiliated with the directors by virtue of their directorship, employment status or share ownership. In addition, in the ordinary course of business and on an arm’s-length basis, certain directors receive broking services from the Company on a personal basis. The Governance Committee determined that, in all of the above cases, the transactions do not impair the relevant director’s independence under the applicable SEC rules, NASDAQ listing standards or the Board’s Director Independence Standards.

Board Meetings and Attendance

The Board met formally 11 times in 2021. Additionally, the Board met informally with management on numerous occasions during the course of the year to discuss, among other things, strategic, operational and management issues. All directors standing for re-election who were on the Board in 2021 attended at least 75% of the aggregate of the total number of Board meetings and of any Committee on which they served in 2021.

The independent directors held separate executive sessions without management either before or after each of the Board’s regularly scheduled meetings in 2021.The Non-Executive Chair of the Board chaired each executive session. Neither the CEO nor any member of management at any level attends the executive sessions of the independent directors unless invited to discuss a particular matter.

All directors are expected to make every effort to attend each Annual General Meeting of Shareholders. All directors standing for re-election who were on the Board in 2021 participated in the 2021 Annual General Meeting of Shareholders.

Board Leadership Structure

As noted above, the members and chairs of each of the Board Committees are independent based on SEC, NASDAQ and governance standards. As a result, independent directors directly oversee such critical matters as the compensation policy for executive officers, nomination and corporate governance practices, and the integrity of financial statements and internal controls over financial reporting.

The Board has determined that the Company and its shareholders are currently best served by having the roles of Board Chair and CEO undertaken by different individuals. In the event they are not, the Corporate Governance Guidelines provide for the appointment of a Presiding Independent Director.

Mr. Ganzi has served as the Independent Non-Executive Chair of the Board since January 1, 2019 and was re-elected by the Board to serve as Chair until the 2022 Annual General Meeting of Shareholders, at which time he will retire from the Board. Following the Annual General Meeting, Mr. Thomas will serve as

Corporate Governance (continued)

the Non-Executive Board Chair for a term to be renewed each year by the Board. Pursuant to the Company’s Corporate Governance Guidelines, the Non-Executive Chair:

Director Orientation and Continuing Education

Director Orientation: Our robust orientation program familiarizes new directors with the Company’s businesses, strategies and policies, and assists new directors in developing company and industry knowledge to optimize their service on the Board. The orientation also provides new directors with an understanding of their fiduciary duties and other requirements associated with serving on the Board of an Irish-domiciled company with shares listed on NASDAQ.

Continuing Education: Regular continuing education programs enhance the skills and knowledge directors use to perform their responsibilities. These programs may include internally developed materials and presentations, programs presented by third parties, and financial and administrative support to attending qualifying academic or other independent programs.

Willis Towers Watson Board Committees

Critical matters such as the compensation policy for executive officers, nomination and corporate governance practices, and the integrity of financial statements and internal controls over financial reporting, and enterprise-wide risk management are overseen by the Board and its Committees, which are comprised solely of independent directors.

The Board Committees, members and a description of each Committee’s function are set forth below in further detail. Each of our Board Committees has its own respective charter, which can be found, along with our Corporate Governance Guidelines in the “Investor Relations — Corporate Governance” section of our website at www.wtwco.com. Copies are also available free of charge on request from the Company Secretary.

Board Committee Slates

Prior Board Committee Composition

As discussed further below, as of January 1, 2022, the Board combined the Audit Committee and the Risk Committee to form the Audit and Risk Committee and created a new Operational Transformation Committee. For the fiscal year 2021, prior to the combination of the Audit Committee and Risk Committee and the formation of the Operational Transformation Committee, the Board Committee composition was as follows:

Current Board Committee Composition

The current Board Committee composition as well as the combined Audit and Risk Committee and formation of the Operational Transformation Committee, is as follows:

Corporate Governance (continued)

General Description of Board Committee Responsibilities

The Audit and Risk Committee generally assists the Board with overseeing the following:

The Audit and Risk Committee’s focus on risk includes, strategic risk, including risks relating to strategic planning and execution, major financial risk exposures and the steps management has taken to monitor and control such risks, including risks relating to internal controls, disclosure controls and procedures, tax and pension matters, and mergers and acquisitions, among other items. In that regard, pursuant to its charter, the Audit and Risk Committee meets annually with the Compensation Committee Chair concerning the Compensation Committee’s risk assessment of the Company’s compensation programs. The Audit and Risk Committee is also responsible for reviewing new material transactions, products or services requiring Board approval and, in that connection, making recommendations to the Board regarding the adequacy of the Company’s resources to performance its risk management responsibilities.

The Audit and Risk Committee provides an avenue for communication among internal audit, the independent auditors, management and the Board. The members of management that join the Committee meetings include, among others, the Chief Financial Officer, the Controller, the General Counsel as well as the Heads of Internal Audit and Compliance. In addition, the Audit and Risk Committee discusses with

Corporate Governance (continued)

management and, if appropriate, the independent auditors, matters such as the guidelines and policies governing the process by which senior management and the relevant departments of the Company assess and manage the Company’s exposure to risk relating to audit, financial disclosure, tax matters, pension matters and foreign exchange hedging. With respect to compliance, the Audit and Risk Committee discusses with the Chief Compliance Officer the compliance and regulatory risks of the Company, and receives a report outlining the main activities of the compliance function, material regulatory interactions review, progress against the annual compliance plan and the adequacy of resources. The Committee also discusses with the General Counsel any significant legal matters that may have a material effect on the Company.

Dr. O’Neill is an independent audit committee financial expert, as defined by Regulation S-K, and all Audit and Risk Committee members are financially sophisticated under NASDAQ listing standards in light of their financial experience. In December 2021, the Board determined to combine the Audit Committee and Risk Committee of the Board. Following its combination, the Audit and Risk Committee did not meet in 2021. The Audit Committee met formally five times in 2021, and the Risk Committee met formally four times in 2021. In addition to holding formal meetings, the Audit Committee and Rick Committee members met informally during the course of the year to discuss and review financial matters related to the Company and its SEC filings (including earnings releases for the Audit Committee). Each of the Committees previously met in executive session frequently, and after its formation, the Audit and Risk Committee also frequently meets in executive sessions, including separate meetings with management, the internal auditors and external auditors.

The Compensation Committee generally assists the Board with the following:

Corporate Governance (continued)

In 2021, the Compensation Committee met formally seven times. In addition to holding formal meetings, the Committee members met informally during the course of the year to discuss compensation-related matters and acted from time to time by unanimous written consent. After regularly scheduled meetings, the Committee also met in executive session, which included meetings with the compensation consultant.

The Corporate Governance and Nominating Committee generally assists the Board with the following:

Corporate Governance (continued)

The Governance Committee believes in fostering strong governance practices and, from time to time, reviews governance principles set out by investors or other outside groups.

In 2021, the Governance Committee met formally four times. After each regularly scheduled meeting, the Governance Committee also met in executive session. In addition to holding formal meetings, the Committee members also met informally on numerous occasions during the course of the year to discuss governance-related matters, including director succession.

The Operational Transformation Committee generally assists the Board with the following:

The Operational Transformation Committee was formed effective as of January 1, 2022, and will have a term ending on December 31, 2024, concurrent with the conclusion of the Company’s operational transformation plan. The Operational Transformation Committee’s risk oversight includes, among other items, technology and information security risk, business continuity, market security processes, supplier management, and material new products and services that create significant operational risks. The Committee did not meet in 2021, but generally holds executive sessions after each Committee meeting and meets informally, as appropriate.

Director Nomination and Selection Process

The Governance Committee identifies potential director nominees by preparing a candidate profile based upon the current Board’s strengths and needs, including based on the Company’s strategy and goals for

Corporate Governance (continued)

the future, and through a variety of sources, including by engaging search firms, considering input from stakeholders or utilizing the professional networks of the Board and senior management. Nominees must meet minimum qualification standards with respect to a variety of criteria including integrity, reputation, judgment, knowledge, experience, maturity, skills and personality, commitment and independence. The Governance Committee may also take into consideration additional factors that it may deem appropriate, which may include, among other factors, diversity, experience with business and other organizations, the interplay of the candidate’s experience with the experience of other Board members and the extent to which the candidate would be a desirable addition to the Board and any committee thereof.

With feedback from the Board members, members of the Governance Committee initiate contact with preferred candidates and, following feedback from interviews conducted by Governance Committee and Board members, recommend candidates to join the Board. The Governance Committee has the authority to retain a search firm to assist with this process. The Governance Committee considers candidates nominated by shareholders and ensures that such nominees are given appropriate consideration in the same manner as other candidates. Recommendations may be submitted to any member of the Governance Committee pursuant to the procedures set forth below under “Communications with Shareholders and Other Constituencies” by writing to the Company Secretary at corporatesecretary@willistowerswatson.com.

The Board’s Role in Risk Oversight

The Company’s management is responsible for the day-to-day management of risks and the Board, including through its Committees, is responsible for understanding and overseeing the various risks facing the Company. Effective risk oversight is an important priority of the Board.

The Board implements its risk oversight function both as a whole and through delegation to its Committees, which meet regularly and report back to the Board. To ensure that the Board executes on its priorities with an appropriate focus on risk generally, effective January 1, 2022, the Board formed a separate Operational Transformation Committee in addition to combining its Audit and Risk Committees. The Board has generally delegated, through respective Board Committee Charters, (i) to the Audit and Risk Committee, the primary responsibility of assisting the Board in its oversight of the enterprise risk management framework, policies and practices used by the Company to identify, assess and manage key risks facing the Company, including financial and strategic risks as well as risks relating to compliance and internal control matters, tax matters and pension matters, among other matters; and (ii) to the Operational Transformation Committee, the oversight of risks arising out of the Company’s operations that support the Company’s businesses, including risks relating to the Company’s operational transformation plan as well as risks related to information security, processes that support quality control within the businesses, business continuity activities and supplier management, among other matters. The Board has also delegated to its other Committees the oversight of risks within their areas of responsibility and expertise. For information on the Board Committees, their responsibilities and areas of risk oversight, see the section above entitled “— General Description of Board Committee Responsibilities” and “— ESG Oversight and Activities.”

In addition, an overall review of risk is inherent in the Board’s consideration of the Company’s long-term strategies and in the transactions and other matters presented to the Board, including capital expenditures, acquisitions and divestitures, and financial matters. The Company believes that its Board leadership and Committee structure supports the risk oversight function of the Board. Moreover, the Board’s role in risk oversight of the Company is consistent with the Company’s leadership structure, with the CEO and other members of senior management having responsibility for assessing and managing the Company’s risk exposure, and the Board and its Committees providing oversight in connection with those efforts. Management regularly communicates with the Board, its Committees and individual directors about significant risks identified and how they are being managed. The Board also oversees management’s crisis preparedness planning.

Corporate Governance (continued)

To learn more about risks facing the Company, review the factors included in Part I, “Item 1A. Risk Factors” in the Company’s Annual Report on Form 10-K for the year ending December 31, 2021 as updated by subsequent filings by the Company with the SEC. The risks described in such filings are not the only risks facing the Company. Additional risks and uncertainties not currently known or that may currently be deemed to be immaterial also may materially adversely affect the Company’s business, financial condition or results of operations in future periods.

ESG Oversight and Activities

In 2019, the Company formed a cross-functional management committee to coordinate and communicate on the Company’s ESG initiatives. Information on our ESG commitments and the various ESG-related awards we have received is available on our website at https://www.wtwco.com/en-US/About-Us/environmental-social-and-governance, which information is not part of or incorporated by reference into this Proxy Statement.

With respect to Board oversight of ESG matters in general, the Board takes an approach that the most appropriate Committee should maintain oversight over a particular issue rather than concentrating all ESG initiatives into any one Committee. The Committees report to the Board as appropriate. For example:

ESG Commitments

Our clients, colleagues and other stakeholders expect us to conduct our business with integrity and in an environmentally and socially responsible manner with the highest ethical standards. We take these expectations seriously and have embraced principles that are aligned with our business priorities, are consistent with our commitment to ethical and sustainable practices and demonstrate our respect for those communities in which we operate across the globe.

Accordingly, our principles reflect an aspirational commitment to:

Corporate Governance (continued)

Corporate Governance (continued)

Additionally, to reinforce our commitments, we have in place our ESG Taskforce to provide central governance over our ESG efforts across the organization and to ensure our commitments are aligned with the Company’s strategic priorities. The ESG Taskforce is sponsored by our General Counsel, Chief Financial Officer and Chief Administrative Officer, and comprises representatives from across the business segments and corporate functions.

Non-Employee Director Compensation

Willis Towers Watson’s non-employee director compensation takes into account, among other things, the Company’s size and complexity as well as the compensation paid by its peer companies and other similarly situated Irish-domiciled, U.S.-listed companies. Outlined below are the fees paid to the non-employee directors for each term of service.

The term of service for the Non-Executive Chair of the Board as well as the Board and its Committees runs from the date of the Annual General Meeting of Shareholders to the date of the next meeting the subsequent year.

Corporate Governance (continued)

The following table sets forth cash and other compensation paid or accrued to the non-employee directors of Willis Towers Watson during 2021. It does not reflect compensation paid to the new directors who joined the Board in 2022.

Corporate Governance (continued)

Share Ownership Guidelines

Under our share ownership guidelines, non-employee directors are required to accumulate Willis Towers Watson shares equal to five times the directors’ annual cash retainer of $125,000 (i.e., $625,000) within eight years of (i) their appointment to the board of their respective legacy company (for legacy Willis Group or legacy Towers Watson directors who serve on the Board) or (ii) their appointment to the Board. The threshold dollar amount is intended to ensure alignment with the Company’s long-term strategy and the time period is intended to attract and retain qualified new board members and candidates. Ordinary shares, deferred shares, share equivalents, RSUs and restricted shares count toward satisfying the guidelines, but options to purchase shares do not. Each director is prohibited from transferring these shares until six months after he or she leaves Board service (other than to satisfy tax obligations on the vesting/distribution of existing equity awards), but is permitted to transfer any shares in excess of this amount. If, as a result of share price decline subsequent to a non-employee director meeting the ownership requirement, the non-employee director no longer satisfies the ownership requirement, he or she is not required to buy additional shares to meet the ownership requirement. In the event a non-employee director has not met the share ownership requirement, he or she is prohibited from transferring any Willis Towers Watson shares (other than to satisfy tax obligations on the vesting/distribution of existing equity awards). In the case of financial hardship, the ownership guidelines may be waived in the discretion of the Compensation Committee until the hardship no longer applies or such other appropriate time as the Compensation Committee determines. All current non-employee directors have satisfied their share ownership requirements.

The following table sets forth the non-employee directors’ equity ownership as of December 31, 2021. It does not reflect the equity granted to the new directors who joined the Board in 2022.

For more information regarding the number of shares beneficially owned by each director as of March 23, 2022, see the section entitled “Additional Information — Security Ownership of Certain Beneficial Owners and Management — Directors, Director Nominees, Named Executive Officers and Other Executive Officers.”

Review and Approval of Related Person Transactions

The Company has adopted written policies and procedures governing the review and approval of transactions between the Company and any of its directors or executive officers, director nominees, any security holder who is known to the Company to own of record or beneficially more than 5% of any class of the Company’s voting securities or their immediate family members (each, a “Related Person”) to determine whether such persons have a direct or indirect material interest. The Company’s directors, director nominees and executive officers complete an annual director and officer questionnaire, which requires the disclosure of Related Person transactions. In addition, directors, director nominees and executive officers are obligated to advise the Audit Committee of any Related Person transaction of which they are aware, or become aware, and, in the event that any such transactions involve difficult or complex

Corporate Governance (continued)

issues, the directors and executive officers are obligated to advise the General Counsel. Further, transactions that are determined to be directly or indirectly material to a Related Person are disclosed in the Company’s Proxy Statement or Annual Report on Form 10-K in accordance with SEC rules. The Audit and Risk Committee reviews and approves or ratifies any Related Person transaction that is required to be disclosed. In the course of its review and approval or ratification of a disclosable related person transaction, the Audit and Risk Committee considers, among other factors it deems appropriate:

Any member of the Audit and Risk Committee who is a Related Person with respect to a transaction under review may not participate in the deliberations or vote regarding the approval or ratification of the transaction, provided, however, that such director may be counted in determining the presence of a quorum at a meeting at which the Audit Committee considers the transaction.

2021 Related Person Transactions under Item 404 of Regulation S-K

BlackRock, Inc. (“BlackRock”) filed a Schedule 13G/A with the SEC reporting that, as of December 31, 2021, BlackRock and certain of its subsidiaries were beneficial owners of more than 5% of our outstanding shares. During 2021, BlackRock Advisors (UK) provided services to Willis Group Services Limited with respect to Willis Pension Trustees Limited and the UK pensions scheme trust. BlackRock received approximately $511,682 for these services and software solutions, which were provided in the ordinary course of business on an arm’s-length basis.

On August 2, 2021, the Company hired Ms. Calyn Haley, Mr. Haley’s daughter, as a senior research associate. Ms. Haley’s base salary is $117,500 and her target STI opportunity, subject to individual and company performance, is 15% of base salary; both are aligned with the compensation structure in place for other broad-based employees in similar roles. Mr. Haley was not involved in any employment or compensation decision by the Company with respect to Ms. Haley. No other transactions are required to be disclosed under Item 404 of Regulation S-K.

Code of Conduct

We have adopted a Code of Conduct applicable to all our directors, officers and employees, including our CEO, the CFO, the Principal Accounting Officer and all those involved in the Company’s accounting functions. Our Code of Conduct can be found in the “Investor Relations — Corporate Governance” section of our website at www.wtwco.com. It is also available free of charge on request from the Company Secretary at corporatesecretary@willistowerswatson.com. We intend to post on our website any amendments to, or waivers of, a provision of our Code of Conduct in accordance with Item 406 of Regulation S-K.

Corporate Governance (continued)

Communications with Shareholders and Other Constituencies

The CEO is responsible for establishing effective communications with the Company’s stakeholder groups, including shareholders, the press, analysts, clients, suppliers, governments and representatives of the communities in which it operates. It is the policy of the Company for the CEO to appoint individuals to communicate and interact fully with these stakeholders. The Chair or another spokesperson chosen by the Board will speak for the Board when the Board determines it is appropriate for the Board to have a distinct and separate spokesperson. Often the Board will look to senior management to speak for the Company; however, the Board is also committed to engaging with shareholders to promote open and sustained dialogue in a manner consistent with the Company’s communications policies and procedures.

Non-employee directors are not precluded from communicating directly with shareholders or other constituencies about Company matters, although directors are required under the Corporate Governance Guidelines to coordinate with the Chair and senior management before doing so. An interested person may communicate with independent directors or the non-management directors as a group by writing to the Company Secretary at corporatesecretary@willistowerswatson.com. The Company Secretary will forward the communication to the director(s) to whom it is addressed.

All communications should include the following information:

Please note that communications may be shared with Company management.

Please see the section “Additional Information — Shareholder and Other Proposals for the 2023 Annual General Meeting” at the end of this Proxy Statement for shareholders seeking to present a proposal for inclusion in the Company’s proxy materials for the 2023 Annual General Meeting of Shareholders.

Shareholder Outreach Program

The Company frequently engages with shareholders. Each year, during the spring and fall seasons, we reach out shareholders holding a majority of our shares and then discuss the feedback with our Board. The purpose of our year- round outreach is to foster relations with our shareholders by enhancing communications on corporate governance, executive compensation and environmental and social issues and providing our shareholders with a forum to discuss any questions they may have or voice any criticisms. We also use the opportunity to explain the various proposals included within the Proxy Statement.

Over the past year, the Company faced different issues and, accordingly, we tailored our shareholder outreach programs to address the various corporate changes. During the 2021 Proxy Season, although the Company was awaiting regulatory approval to potentially combine with Aon, management still believed it was important to continue to reach out to its main institutional investors to discuss the Proxy Statement and its rationale for the executive compensation program, corporate governance structure and ESG initiatives. Shareholders were generally supportive of the Company’s proposals, which is evidenced by our 2021 Say-on-Pay proposal to approve the NEOs’ compensation receiving approximately 95.92% of the votes cast in favor at the 2021 Annual General Meeting of Shareholders.

Corporate Governance (continued)

After the Aon transaction was terminated, in August 2021, the Board appointed Mr. Hess as President and future CEO. Again, management took the opportunity to reach out to shareholders representing approximately 50% of the outstanding shares to offer an introductory call with Mr. Hess. Other management attendees included, among others, our then-current CFO, Head of Investor Relations and/or General Counsel. Management then held an Investor Day in early September to explain its going-forward strategy.

In the fall, management continued the conversations with investors and offered the opportunity to discuss governance, compensation and other ESG highlights, including governance actions the Board has recently taken and expects to take, as well as expectations for the upcoming Proxy Season.

In light of the new strategy unveiled at Investor Day, the Company undertook a review and redesign of 2022 executive officer incentives, which considered shareholder feedback, as detailed in the section entitled “Executive Compensation: Compensation Discussion and Analysis— Executive Officer 2022 Incentive Design Update.” The Board also continued its succession plan, which included announcing the appointment of four new independent directors see section entitled “Proposal No. 1: Elect Directors — Board and CEO Succession.”

Vote Required for Special Meetings

Shareholders holding 10% of the Company’s share capital have the ability to convene a special meeting.

Proposal No. 2: Advisory (Non-binding) Vote to Ratify the Appointment of the Independent Auditors and a Binding Vote to Authorize the Board of Directors, Acting through the Audit and Risk Committee, to Fix the Independent Auditors’ Remuneration

For the fiscal year ending December 31, 2022, the Willis Towers Watson Audit and Risk Committee approved, and the Board ratified, the appointment of (i) Deloitte & Touche LLP, Independent Registered Public Accounting Firm, to audit the financial statements of Willis Towers Watson and (ii) Deloitte Ireland LLP, Independent Statutory Audit Firm, to audit the Irish Statutory Accounts of Willis Towers Watson. Deloitte & Touche LLP and Deloitte Ireland LLP are the respective U.S. and Irish member firms of the Deloitte Touche Tohmatsu Limited network.

We are seeking ratification of both of these appointments in a non-binding advisory vote from our shareholders at the 2022 Annual General Meeting of Shareholders. We are not required to have our shareholders ratify the appointments of our independent auditors, but we are nonetheless doing so because we believe it to be a matter of good corporate governance practice. If our shareholders do not ratify the appointments, it will be regarded as notice to the Board and the Audit and Risk Committee to consider selecting different firms. Even if the appointments are ratified, the Audit and Risk Committee may select different independent auditors at any time if it determines that such selections would be in the best interest of Willis Towers Watson and our shareholders.

The Board unanimously recommends that you vote, on a non-binding advisory basis, “FOR” the ratification of the appointment of (i) Deloitte & Touche LLP as the Company’s Independent Registered Public Accounting Firm and (ii) Deloitte Ireland LLP as the Company’s Statutory Audit Firm for the Irish Statutory Accounts; and, on a binding basis, the authorization of the Board, acting through the Audit and Risk Committee, to fix the independent auditors’ remuneration.

A majority of the votes cast by shareholders at the 2022 Annual General Meeting of Shareholders is required for the proposals. We expect that one or more representatives of Deloitte & Touche LLP and Deloitte Ireland LLP will be present at the 2022 Annual General Meeting of Shareholders. Each of these representatives will have the opportunity to make a statement, if he or she desires, and is expected to be available to respond to appropriate questions.

The Audit and Risk Committee reviews the auditors’ independence and performance in deciding whether to retain them or engage different independent auditors. In the course of this review, the Committee considers, among other things, the auditors’:

Fees Paid to the Independent Auditors

The fees that the Company incurs for audit, audit-related, tax and other professional services reflect the complexity and scope of the Company’s operations, including:

The following fees have been, or will be, billed by Deloitte & Touche LLP or its respective affiliates for professional services rendered to Willis Towers Watson for the fiscal years ended December 31, 2021 and December 31, 2020 ($ in thousands).

Audit and Risk Committee Pre-approval Process

The Audit and Risk Committee has adopted a policy regarding the pre-approval of services provided by the Company’s independent auditors, which can be found in the “Investor Relations — Corporate Governance” section of the Company’s website at www.wtwco.com. This policy requires all services provided by the Company’s independent auditors, both audit and permitted non-audit services, to be pre-approved by the (i) Audit and Risk Committee, (ii) the Audit and Risk Committee Chair or (iii) in the Chair’s absence, any other independent member of the Committee ((ii) and (iii) defined as a “designated member”). The decisions of a designated member of the Audit and Risk Committee shall be reported to the Audit and Risk Committee at its next regularly scheduled meeting.

The pre-approval of audit and permitted non-audit services may be given at any time before engagement for a specified service. Further, the policy outlines the audit and non-audit services that have been pre-approved by the Audit and Risk Committee. Pre-approval fee levels for these services to be provided by the independent auditor will be established by the Audit and Risk Committee at an annual fee meeting and pre-approved for the 12 months thereafter. All other services not listed in the policy must be

Proposal No. 2: Advisory (Non-binding) Vote to Ratify the Appointment of the Independent Auditors and a Binding Vote to Authorize the Board of Directors, Acting through the Audit and Risk Committee, to Fix the Independent Auditors’ Remuneration (continued)

specifically pre-approved by the Audit and Risk Committee or a designated member. For pre-approved services that arise between regularly scheduled Committee meetings and exceed the pre-approval fee levels set in the annual fee meeting, the Audit and Risk Committee has pre-approved an additional pre-established fee level, which is to be administered by the Controller. The Audit and Risk Committee approved all services described in the “— Fees Paid to the Independent Auditors” section above in accordance with this policy.

Audit and Risk Committee Report

The Audit and Risk Committee is currently composed of six non-employee directors: Brendan O’Neill (Chair), Paul Thomas, Anna Catalano, Wilhelm Zeller, Fumbi Chima and Dame Inga Beale. Dr. O’Neill is an independent audit committee financial expert, as defined by Regulation S-K, and all Audit and Risk Committee members are considered to be financially sophisticated under NASDAQ listing standards in view of their respective financial expertise.

The Audit and Risk Committee operates under a Charter, which is described in detail under “Corporate Governance — Willis Towers Watson Board Committees.” Among its other responsibilities described in its Charter referenced above, the Audit and Risk Committee assists the Board in its oversight of the quality and integrity of the Company’s financial reporting, internal controls over financial reporting, financial management processes and risk management at the Company and subsidiary level as well the appointment, retention, performance and compensation of the Company’s independent auditor. The Audit and Risk Committee meets with members of management, including the Chief Financial Officer, the Controller, the General Counsel as well as the Heads of Internal Audit, Compliance and Risk. The Audit and Risk Committee’s focus on risk relates to major financial risk exposure, pertaining to, among other items, regulatory, audit, financial disclosure, tax matters, pension matters and foreign exchange hedging, and the steps management has taken to monitor and control such risks. Executive management is responsible for the Company’s financial statements and overall reporting process, including the system of internal controls. The independent auditors are responsible for conducting annual audits and quarterly reviews of the Company’s financial statements in accordance with auditing standards of the PCAOB and expressing an opinion as to the conformity of the annual financial statements with U.S. generally accepted accounting principles (“GAAP”). With respect to compliance, the Audit and Risk Committee discusses with the Chief Compliance Officer the compliance and regulatory risks of the Company, and receives a report outlining the main activities of the compliance function, material regulatory interactions review and progress against the annual compliance plan.

In the performance of its oversight function, the Audit and Risk Committee has reviewed and discussed the audited financial statements as of and for the year ended December 31, 2021, with management and the independent auditors. These discussions included the quality, the clarity of the disclosures and the appropriateness of the accounting principles and underlying estimates and other communications required to be discussed under PCAOB standards. The Audit and Risk Committee has also discussed with the auditors, the auditors’ independence from Willis Towers Watson and its management, including the written disclosures and the report received from the auditors regarding the auditors’ communications with the Audit and Risk Committee concerning independence as required by the PCAOB in Rule 3526, Communication with Audit Committees Concerning Independence. The independent auditors and the Company’s internal auditors had full access to the Audit Committee, including at regular meetings without management present.

It is not the duty or responsibility of the Audit and Risk Committee to conduct auditing or accounting reviews or procedures. In performing their oversight function, members of the Audit and Risk Committee rely, without independent verification, on the information provided to them and on the representations made by management and the independent auditors. Accordingly, the Audit and Risk Committee’s

Proposal No. 2: Advisory (Non-binding) Vote to Ratify the Appointment of the Independent Auditors and a Binding Vote to Authorize the Board of Directors, Acting through the Audit and Risk Committee, to Fix the Independent Auditors’ Remuneration (continued)

considerations and discussions do not assure that the audit of the Company’s financial statements has been carried out in accordance with GAAP or that the financial statements are presented in accordance with GAAP.

Based upon the review and discussions described in this report, and subject to the limitations on the role and responsibilities referred to above, the Audit and Risk Committee agreed that the audited financial statements referred to above be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC.

Submitted by the Audit and Risk Committee of the Board of Directors of Willis Towers Watson Brendan O’Neill (Chair), Dame Inga Beale (Committee member as of January 1, 2022), Anna Catalano, Fumbi Chima (Committee member as of April 1, 2022), Paul Thomas and Wilhelm Zeller

Proposal No. 3: Advisory (Non-binding) Vote on Named Executive Officer Compensation

Recognizing that executive compensation is an important matter for our shareholders, and in accordance with SEC rules, we are asking our shareholders to approve an advisory resolution on the compensation of our named executive officers as disclosed in this Proxy Statement.

This proposal, commonly known as a “say-on-pay” proposal, is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and our executive compensation philosophy, policies and practices as described in this Proxy Statement. Although the voting results are not binding, the Board and the Compensation Committee will take into account the results of the vote when considering future executive compensation arrangements.

We encourage our shareholders to read the Compensation Discussion and Analysis, which immediately follows this proposal. The Compensation Discussion and Analysis describes in more detail our executive compensation program and related policies and practices and explains the decisions the Compensation Committee has made under this program and the factors considered in making those decisions. We also encourage our shareholders to review the 2021 Summary Compensation Table and other related compensation tables and narratives, which provide detailed information on the compensation of our named executive officers.

Accordingly, we ask our shareholders to vote “FOR” the following resolution, which requires the affirmative vote of a majority of the votes cast:

“RESOLVED, that the shareholders of Willis Towers Watson Public Limited Company approve, on an advisory basis, the compensation of the Company’s named executive officers as disclosed in the Company’s Proxy Statement for the 2022 Annual General Meeting of Shareholders in accordance with the SEC’s rules, including in ‘Executive Compensation: Compensation Discussion and Analysis,’ ‘Compensation Tables — Summary Compensation Table’ and related tables and disclosure.”

The Board of Directors unanimously recommends a vote “FOR” the advisory (non-binding) resolution approving the overall executive compensation of Willis Towers Watson’s named executive officers, described in this Proxy Statement pursuant to the compensation disclosure rules of the SEC.

Executive Compensation: Compensation Discussion and Analysis

The Compensation Discussion and Analysis (“CD&A”) describes our compensation philosophy and provides an overview and analysis of (i) our 2021 compensation programs and policies for our named executive officers (“NEOs”); (ii) the material compensation decisions made by the Compensation Committee under those programs and policies as reflected in the executive compensation tables that appear following this CD&A; and (iii) the material factors that the Compensation Committee considered and the process it utilized in making those decisions.

Executive Compensation Overview

Key 2021 Company Highlights

Solid Financial Performance¹ Despite COVID-19 and a Shift in Strategy

2021 served as a transformative year for Willis Towers Watson Public Limited Company (WTW). Solid Company performance throughout the year demonstrated the resilience of WTW’s colleagues and a diversified portfolio of products and services, amid challenges caused by the COVID-19 pandemic and a shift in WTW’s strategy as an independent company. Despite these unprecedented circumstances, the Company continued to serve our clients, protect our colleagues and safeguard our business fundamentals.

Executive Compensation: Compensation Discussion and Analysis (continued)

With the COVID-19 pandemic, the Company continued its comprehensive set of global processes to stabilize business operations while providing high quality service to clients. This included ongoing global business continuity and incident management efforts to restrict travel, limit office access and enhance our global workforce to a work-from-home protocol with split team operations for our essential workers. The Company regularly considered the impact of the pandemic on our business and stress tested the rigor of our business resilience, continuity plans, forecasting and liquidity management. Throughout 2021, the Company took decisive measures to reinforce working capital discipline and reduce discretionary spending.

From March 2020 through July 2021, the Board and leadership drove the Company towards the closing of the business combination with Aon, which would have been an all-stock transaction with a combined equity value of approximately $80 billion. One of the goals of the combination was to accelerate elements of the Company’s pre-existing strategy. At the same time as leadership was driving towards the closing of the transaction, they were also managing the day-to-day business of the Company. When the proposed Aon combination was terminated in July, after almost 18 months of integration planning and closing preparations and after a period of substantial uncertainty, the Board and leadership quickly shifted their attention to supporting the Company on an independent path. With the combination no longer feasible, the Company took decisive actions to accelerate its standalone strategy and aggressive steps to retain colleagues and recruit new talent, to enhance its ability to serve clients and to create value for stakeholders. In particular, the Company quickly announced a CEO successor, hired a new CFO and took significant steps to refresh the Board; transformed its senior management structure through the creation of a new Global Leadership Team and simplified the Company’s organizational structure; sold its treaty reinsurance business, generating several billion dollars of capital for focused investments and share repurchases; and created and launched an ambitious strategic plan to grow, simplify and transform with plans to refresh the WTW brand.

These actions, combined with the commitment of our leaders and colleagues, helped WTW deliver solid financial results in 2021 and position the Company for future years.

Certain key highlights of these efforts and our financial results are described below.

CEO and Board Succession; Global Leadership Team Transformation

Once on an independent path forward, the Board revisited its CEO succession plan and, by August, had appointed Mr. Hess as the Company’s President as of September 1, 2021 and CEO as of January 1, 2022. Mr. Hess succeeded Mr. Haley as CEO following Mr. Haley’s previously scheduled retirement on December 31, after his decades-long tenure. Additionally, Mr. Krasner was appointed as the new CFO in early September, by which time Mr. Haley and Mr. Hess had established a new management structure and appointed the members of the new Global Leadership Team. Members of the Global Leadership Team also developed and presented multi-year strategic plans to the Company’s stakeholders during the Company’s Investor Day on September 9. At Investor Day, the Company announced plans to complete approximately $4 billion in share repurchases by 2022, $1.6 billion of which has been repurchased by December 31. Throughout the fall, management continued its shareholder outreach programs to introduce Mr. Hess, maintain and strengthen relationships and understand shareholder feedback. On December 1, Arthur J. Gallagher & Co. completed the principal closing of its acquisition of the Company’s treaty reinsurance business under the Security and Asset Purchase Agreement, dated as of August 13.

By the end of December, after revisiting its refreshment plan, the Board announced the addition of four new directors before the 2022 Annual Meeting, in addition to Mr. Hess, and the retirement of six then-current directors (including Mr. Haley) by no later than the Annual Meeting. The Board also reconstituted the Board Committee slates as discussed further in the section entitled “Corporate Governance — Willis Towers Watson Board Committees.”

Executive Compensation: Compensation Discussion and Analysis (continued)

Effective January 1, 2022, we provide our comprehensive offering of services and solutions to clients across two rather than four business segments: Health, Wealth and Career (“HWC”) and Risk and Broking (“RB”). These changes were made in conjunction with changes in the Global Leadership Team.

Strategy Acceleration: Grow, Simplify and Transform

The multi-year strategic plans presented at Investor Day articulated the steps the Company would take to help accelerate performance and position WTW for a bold new future, including executing on the following:

Focusing on these priorities is intended to benefit all Company stakeholders and we believe will better position us against our peers.

Compensation Practices at a Glance

We maintain a comprehensive compensation and governance framework aligned with market practices and standards.

What We Do:

What We Don’t Do:

Shareholder Engagement and Say-on-Pay

The Company frequently engages with shareholders. Each year, during the spring and fall seasons, we reach out to shareholders holding a majority of our shares and discuss the feedback with our Board. The purpose of our year- round outreach is to foster relations with our shareholders by enhancing communications on corporate governance, executive compensation and environmental and social issues and provide our shareholders with a forum to raise questions or voice any criticisms. We also use the opportunity to explain the various proposals included within the Proxy Statement.

Executive Compensation: Compensation Discussion and Analysis (continued)

Over the past year, the Company tailored our shareholder outreach programs to address the various corporate changes. During the 2021 Proxy Season, although the Company was awaiting regulatory approval to potentially combine with Aon, management believed it was still important to continue to reach out to its main institutional investors to discuss the Proxy Statement and its rationale for the executive compensation program, corporate governance structure and ESG initiatives. Shareholders were generally supportive of the Company’s proposals, which is evidenced by our 2021 Say-on-Pay proposal to approve the NEOs’ compensation receiving approximately 95.92% of the votes cast in favor at the 2021 Annual General Meeting of Shareholders.

After the Aon transaction was terminated, in August 2021, the Board appointed Mr. Hess as President and future CEO. Again, management took the opportunity to reach out to shareholders representing approximately 50% of the outstanding shares to offer an introductory call with Mr. Hess. Other management attendees included, among others, our then-current CFO, Head of Investor Relations and/or General Counsel. Management then held an Investor Day in early September to explain its going-forward strategy.

In the fall, management continued the conversations with investors and offered the opportunity to discuss governance, compensation and other ESG highlights, including governance actions the Board has recently taken and expected to take, as well as expectations for the upcoming Proxy Season.

The Governance and Compensation Committees are both involved in the outreach program. Generally, we review our outreach plans and the results of our outreach efforts and discuss any significant feedback with both Committees (and the full Board, as appropriate). In light of the new strategy unveiled at Investor Day, the Company undertook a review and redesign of 2022 executive officer incentives, which considered shareholder feedback, as detailed in the section entitled “ — Executive Officer 2022 Incentive Design Update.” The Board also continued its succession plan, which included announcing the appointment of four new independent directors as discussed in the section entitled “Proposal No. 1 — Board and CEO Succession.”

Our Executive Compensation Program in Detail

Our Pay Philosophy

The main objectives of the Company’s executive compensation program are to attract, motivate and retain highly qualified executives and align their interests with our strategy of maximizing shareholder value. In addition, the Compensation Committee believes it is important for the Company’s executive officers’ interests to be aligned with each other to drive profitable growth.

The Compensation Committee has placed an emphasis on variable pay; 90% of Mr. Hess’s target total direct compensation as CEO is performance-based and, on average, 74% of the other NEOs’ (who are current executives) target total direct compensation is performance-based. The Compensation Committee does not have an explicit pay positioning strategy relative to market, but rather evaluates a number of factors, including role, tenure, experience, contribution and performance, as well as comparisons to peers, among other factors, in determining appropriate target pay opportunities.

Although the Compensation Committee looks at each component of compensation (base salary, STI, LTI and pension) separately, it also looks at the total rewards package to ensure competitiveness, incenting top performance, internal equity among the executive team members and shareholder alignment. The table below reflects the 2021 compensation design for the NEOs.

Executive Compensation: Compensation Discussion and Analysis (continued)

Components of the Named Executive Officers’ 2021 Compensation

The discussion below provides additional detail about each component of the Company’s compensation program.

Base Salary

The Compensation Committee strives to set base salary at a competitive level based on an executive’s position and the relevant markets in which the executive operates. The Compensation Committee generally does not provide annual merit increases to executives, but rather rewards exceptional performance through STI and/or LTI awards. Adjustments to base salaries are made by the Compensation Committee to reflect changes in responsibilities or when competitive market or internal conditions warrant. During 2021, Mr. Hess’s base salary was increased from $650,000 to $1 million effective September 1, 2021 in connection with his promotion to President of the Company and his expanded responsibilities in the role. No other NEO received a salary increase during 2021. In February 2022, the Compensation Committee approved an increase to Mr. Furman’s base salary from $550,000 to $590,000 effective April 1, 2022, reflecting his first base salary increase since joining the Company.

Short-Term Incentive Compensation

STI awards are an integral component of the NEOs’ total compensation and they are intended to deliver exceptional pay for exceptional performance and provide a well- timed link between recent performance and individual compensation.

Executive Compensation: Compensation Discussion and Analysis (continued)

Each NEO is eligible to receive an annual STI award with a target value expressed as a percentage of his or her base salary. The targets were established by the Compensation Committee based on an evaluation of each executive officer’s total compensation, market practice and preexisting employment arrangements. During 2021, the Committee increased Mr. Hess’s STI target from 90% to 175% of base salary in connection with his promotion to President of the Company. No other changes were made to STI target opportunities for the NEOs in 2021.

2021 STI Program Design

In light of the significant business uncertainty that was created by the COVID-19 pandemic and then-pending Aon transaction, in June 2020, the Compensation Committee adopted changes to the 2020 STI Program that were continued for the 2021 performance year. More specifically, the Committee (i) eliminated separate business segment, geography and functional performance components, (ii) eliminated defined performance metric payout grids at the enterprise level and (iii) applied the same component weightings and performance measures for all executive officers. The Committee placed a greater emphasis on enterprise financial performance (80% of STI opportunity) than individual performance (20% of STI opportunity), which was further aligned to the bonus funding for the broader employee base creating greater colleague cohesiveness. The objectives of these changes were to: (i) align the rewards of executive officers from different business and geographic units to promote an even more unifying team mindset to help in response to the pandemic, with its varied impacts on different business units within the Company, (ii) more fully align the rewards for the senior executive team with the rest of the Company’s employees during this period of economic uncertainty and (iii) reduce the potential volatility in payout levels driven by unanticipated and uncontrollable business impacts of the pandemic.

2021 STI Awards

The following table sets forth the STI awards approved by the Compensation Committee and paid in cash to the NEOs for the fiscal year ended December 31, 2021.

Executive Compensation: Compensation Discussion and Analysis (continued)

The Total 2021 STI Awards reflect the NEOs’ 2021 STI Target Opportunity as impacted by the 2021 bonus pool funding percentage for the broader employee base (i.e., 124.5%). The bonus pool for the broader employee population is based on total enterprise financial performance, including adjusted operating income and revenue growth, which is evaluated in comparison to budget and prior year results. The Company determines what it believes is a reasonable level of total discretionary compensation funding (including bonuses) that balances both colleague rewards, as well as return on investment to shareholders. The discretionary compensation funding for the broader employee population is reflected in the Company’s financial statements which are reviewed with the Audit and Risk Committee.

The Compensation Committee concluded that the enterprise financial performance component of the NEO’s STI awards had been fully achieved and approved the NEOs’ 2021 STI awards by applying the broader employee base bonus pool funding percentage for 2021 of 124.5% (or in Mr. Krasner’s case, the bonus pool funding percentage accrued during his time spent working for the Company in 2021 of 108%) to the enterprise financial performance component of the award. The rationale was that the overall funding percentage for STI awards for executive officers (as a percentage of target) should mirror the funding percentage for STI awards made to the broader base of employees eligible for such awards and that executive officers from different business and geographic units, all impacted differently by challenges during the year, would be more closely aligned. The approach was intended to promote an even more unifying, team mindset, thereby helping the Company manage the uncertainty the Company faced during the year. The enterprise-wide bonus funding percentage reflected the Company’s strong financial results and colleagues’ resilience during an uncertain year, as discussed in the section above entitled “— Key 2021 Company Highlights.”

When assessing the individual performance of each NEO, the Compensation Committee considered the achievements of a range of factors, including CEO recommendations. In light of Mr. Haley’s retirement at the end of the year, Mr. Haley met with the then-current Compensation Committee members several times over the course of 2021 to provide his recommendations for the individual achievements of the NEOs based on the first and second half of the performance year. For all NEOs, the final individual performance result reflects a blend of assessments of the first and second half year of performance.

As described below, these included, among other things, overall enterprise level contributions through leadership of his or her respective business segment or function, particularly in light of the uncertainty the Company faced in 2021, quality of underlying financial achievement and contributions to strategic goals in a transformative year. Because 80% of the 2021 STI Program design was tied to the promotion of enterprise financial achievement, the Compensation Committee applied the enterprise-wide bonus funding percentage of 124.5% (108% in the case of Mr. Krasner) to the level of achievements set forth in the table below.

The Compensation Committee also included inclusion and diversity objectives as part of each NEO’s 20% individual performance component, which are reflected in the achievements below. For a more detailed discussion of the Company’s commitment to inclusion and diversity, see the “Business — Human Capital” section in Part I, Item 1 of our Annual Report on Form 10-K, filed with the SEC on February 24, 2022.

Long-Term Incentive Compensation

LTI compensation is a significant element of our executive officer compensation and is granted in the form of equity awards under the Company’s 2012 Equity Incentive Plan (the “2012 Plan”). The NEOs’ 2021 LTI awards (including the CEO’s) were consistent with the design of the NEOs’ 2020 LTI awards.

2021 LTI Program

Messrs. Hess, Furman and Burwell and Ms. Gebauer received their 2021 LTI Awards on July 20, 2021, as was customary for the most senior executive team.

Mr. Hess and Ms. Gebauer each had a 2021 LTI target of 150% of base salary, Mr. Furman had a 2021 LTI target of $750,000 per terms of his employment agreement and Mr. Burwell had a 2021 LTI target of 200% of base salary. Mr. Krasner did not receive a 2021 LTI award but received a make whole sign-on equity award of $3 million in time-based RSUs on September 7, 2021 per terms of his offer letter. Mr. Burwell’s 2021 LTI award was forfeited upon his departure from the Company in September 2021.

The NEOs’ 2021 LTI awards were granted on the same performance and payout terms as the 2020 and 2019 LTI awards. To align management’s and shareholders’ interests, the awards were 100% performance-based in the form of PSUs. The Compensation Committee and management conduct an
