. Board and Committee Performance Evaluation Our Board of Directors and each committee perform an annual performance self-evaluation to assess, at a minimum, the effectiveness and adequacy of the meetings of the Board of Directors and its committees, the adequacy and timeliness of information provided to the Board of Directors by our management team, the diversity of experience of individual directors and the contributions of each director. The evaluation process is overseen by the Nominating and Corporate Governance Committee. As a result of this annual process, the Board and each of its committees functioned well together, and the members of our Board of Directors were satisfied with the overall performance of the Board and each of its committees.
