Each year, the Board, as required by the Corporation’s Corporate Governance Guidelines, conducts an evaluation of its performance and effectiveness. As set forth in its charter, the Nominating and Corporate Governance Committee oversees this process. The annual process begins with the Nominating and Corporate Governance Committee reviewing and revising the Board and committee questionnaires each fall. The questionnaires solicit feedback on a range of issues, including Board and committee structure, culture, effectiveness and dynamics, meeting content, and interactions with management. Every third year, the Board engages an independent third-party to review the Board’s practices and effectiveness and conduct independent one-on-one interviews with each of the directors on topics similar to those included in the questionnaires. The most recent third-party review was conducted in the fall of 2024.

The results of the third-party review are presented to the Nominating and Corporate Governance Committee for review and discussion. The results are then reviewed by each committee and the entire Board. In response to feedback received during prior evaluation processes and the most recent third-party review, the Board appointed two additional directors in March 2025 with deep digital and IT experience.
