TABLE OF CONTENTS

Director Qualifications and Nomination Process Annual Assessment of Size, Composition and Structure The Board strives to maintain an appropriate balance of tenure, turnover, characteristics, skills and experience. Our average director tenure is approximately seven years, representing an appropriate balance of tenures. The Board does not maintain term limits and in 2023 the Board amended the Company’s Governance Guidelines to remove the mandatory retirement age for directors, as the Board believes that continuity of service can provide stability and valuable insight. The Board ensures refreshment and continued effectiveness through evaluation, nomination, and other policies, processes and practices.

For example:

| • | The Nominating and Corporate Governance Committee annually reviews with the Board the qualifications for Board members and the composition of the Board as a whole. |

| • | The Nominating and Corporate Governance Committee annually reviews each director nominee’s continuation on the Board and makes recommendations to the full Board. |

| • | The Company’s Governance Guidelines provide that any director who changes the nature of the job he or she held when elected to the Board should volunteer to resign to give the Board the opportunity to review the appropriateness of continued Board membership under the circumstances. |
