Director Continuing Education As part of our efforts designed to ensure a continuing high-performance Board, Directors participate in continuing education on current topics and developments. We bring outside experts into the Board room to review current topics and developments in their areas of expertise, and Directors regularly attend outside education sessions on relevant topics.

Our Directors generally hold executive sessions at both the beginning and end of each Board meeting. As Lead Director, Mr. Singleton presided over these executive sessions. In addition, Mr. Singleton has broad authority to call and conduct meetings of the independent Directors. The duties and responsibilities of our Lead Director are described in more detail in the section below.
