This document is a sixth edition of a handbook that provides guidance to corporate directors and officers on fulfilling their fiduciary duties. It discusses the roles and responsibilities of directors and officers, as well as the fiduciary duties of care, loyalty and good faith. It also examines how these duties apply in specific contexts such as business transactions, takeovers, going private transactions, the use of special committees, and periods of insolvency or dissolution. The handbook is intended to be both an authoritative legal resource and a practical tool to help directors and officers address real-world governance challenges.
