 the Company since 2013, serving as the Chair of the Compensation Committee since 2016. His proven leadership on the Compensation Committee further enables a well-functioning Board and helps facilitate effective Board communication and governance. His extensive executive experience also positions him to be a highly versatile intermediary on the Board.

Additionally, the Board, which consists entirely of independent directors other than Mr. Chambers, exercises an independent oversight function. Each of the Board committees, other than the Executive Committee, is comprised entirely of independent directors. Regular executive sessions of the independent directors are held. On an annual basis, each of the independent directors evaluates the Chair and CEO in several key areas.

The Board has complete access to the Company’s management and believes that its ongoing ability to review the leadership structure of the Board and to make changes as it deems necessary and appropriate gives it the flexibility to meet varying business, personnel, and organizational needs over time.
