A bank's board of directors plays a critical role in the successful operation of the bank. The health of a bank depends on a strong, independent, and attentive board that adopts effective corporate governance practices. The board has the fundamental responsibility of directing the management of the bank's business and affairs, and establishing a corporate culture that prevents the circumvention of safe and sound policies and procedures. In addition, directors have certain fiduciary responsibilities to the bank's shareholders, depositors, regulators, and communities it serves.
