Warren Buffett on Business: Principles from the Sage of Omaha

E.4. 4. Director Responsibilities

The basic responsibility of the directors is to exercise their business judgment to act in what they reasonably believe to be in the best interests of the Company and its shareholders, and to conduct themselves in accordance with their duties of care and loyalty. Directors are expected to attend Board meetings and meetings of the committees on which they serve, and to spend the time needed to carry out their responsibilities as directors, including meeting as frequently as necessary to properly discharge those responsibilities. Directors are also expected to review in advance all materials for the meetings of the Board and the Committee(s) on which they serve.
