The chairman is responsible for the leadership of the board, and for the efficient functioning of the board. The chairman must ensure that all directors receive an agenda, minutes of prior meetings, and adequate background information in writing before each board meeting and when necessary between meetings. Therefore it is vital that the chairman commit sufficient time to perform his role effectively. All directors must receive the same board information. At the same time, directors have a legal duty to inform themselves and they must ensure that they receive adequate and timely information and must study it carefully (See also Chapter HC-7 for other duties of the chairman).
