Aon plc Governance Guidelines



  1. Election of Directors

  2. All directors are elected each year at the Annual General Meeting to serve until the next Annual General Meeting, and shall hold office, in accordance with the articles of association (the “Articles”) of Aon plc (the “Company”), until his or her successor is elected or until his or her earlier retirement or removal in accordance with the Articles.

  3. Director Qualifications and Selection

  4. The Company shall have a majority of directors who meet the categorical standards of independence adopted by the Board of Directors (the “Board”). The categorical standards will meet or exceed the independence requirements of the New York Stock Exchange (the “NYSE”), as the same may be amended from time to time.

    The Governance/Nominating Committee is responsible for identifying, considering and recommending to the Board candidates for Board membership. In identifying candidates, the Governance/Nominating Committee and the Board seek members from diverse backgrounds who combine a broad spectrum of experience and expertise with a reputation for integrity. Directors should have experience in positions with a high degree of responsibility, be leaders in the organizations with which they are affiliated, be selected based upon contributions they can make to the Board and management and be free from relationships or conflicts of interest that could interfere with the director’s duties to the Company and its shareholders.

    The Governance/Nominating Committee is responsible for reviewing with the Board, on an annual basis, the requisite skills and characteristics of prospective directors as well as the composition of the Board as a whole. This assessment will include an affirmative determination of each prospective director’s qualification as independent, as well as a consideration of integrity, diversity, leadership, the ability to carry out the duties of a director, and skills and experience in the context of the needs of the Board.

  5. Chairperson

  6. The Board will periodically appoint a Chairperson of the Board. All directors, including the Company’s Chief Executive Officer (the “CEO”), are eligible for appointment as the Chairperson. If the Chairperson is not an independent director, the Board will either designate an independent director (the “Presiding Director”) to preside at the meetings of independent or nonmanagement directors or a procedure by which a presiding director is selected for these meetings. The Company will appropriately disclose the name of this presiding director or method by which interested parties may contact the independent or nonmanagement directors. The Board will assess its leadership structure from time to time to ensure that the leadership structure is the most appropriate for the Company.

  7. Director Responsibilities

  8. The basic responsibility of a director is to exercise his or her business judgement and act in what he or she reasonably believes to be in the best interests of the Company and its shareholders as a whole. In discharging these obligations, a director should be entitled to rely on the honesty and integrity of the Company’s senior executives and the Company’s outside advisers and auditors.

  9. Attendance at Meetings

    Directors are also expected to attend the Annual General Meeting.

  11. Size of the Board

  12. The Board will determine its size within a range of no less than 7 and no more than 21 members as required by the Company’s Articles. The Board currently believes that a range of no less than 9 and no more than 15 members is appropriate. The precise number will be determined from time to time by resolution adopted by a majority vote of directors in office at the time of the vote. The Governance/Nominating Committee may from time to time make recommendations for changing the number of directors serving on the Board.

  13. Selection of New Directors

  14. The Governance/Nominating Committee, with direct input from each of the Chairperson and the CEO, will identify, consider and recommend to the Board qualified individuals to become directors. The Governance/Nominating Committee will make recommendations to the Board for approval.

  16. Board Evaluation The Board will conduct an annual self-evaluation to review the performance of the Board and its committees. The Governance/Nominating Committee will provide oversight of the annual review of Board performance, including the peer review evaluation. The Governance/Nominating Committee will receive comments from all directors and report to the Board with an assessment of the Board’s performance and any recommendations following each such review. In conducting the evaluation process, the Governance/ Nominating Committee may choose to review the practices of other boards of directors; circulate surveys, questions and evaluation forms; hire outside consultants and advisors; and use such other methods as it may deem helpful and appropriate. All directors are free to make suggestions as to the improvement of the Board’s practices at any time and are encouraged to do so.

    Peer Review The Board will conduct an annual peer review. The Chairperson of the Governance/ Nominating Committee shall discuss the results of the peer review with each individual director.

    Based on the results of the peer review and any other factors the Governance/Nominating Committee deems appropriate and relevant to a director’s continued service on the Board, and following discussion with each of the Chairperson and the CEO, the Governance/Nominating Committee will recommend to the full Board whether a director should be nominated for election at the Annual General Meeting, and consider changes in the incumbent directors, if such changes are deemed appropriate.
