. Introduction to Duty of Loyalty

The duty of loyalty is a fundamental fiduciary obligation requiring directors and officers to act in the best interests of the corporation and its shareholders, rather than in their own personal interest or for the benefit of third parties.

Key idea: A director must put the corporation’s interests above personal gain, avoiding conflicts of interest and self-dealing.

2. Core Principles of Duty of Loyalty

Avoid Self-Dealing
Directors must not use corporate opportunities or assets for personal benefit without full disclosure and consent.

Disclosure of Conflicts of Interest
Any personal or external interest that may affect a director’s judgment must be disclosed to the board.

Corporate Opportunity Doctrine
Directors cannot take opportunities that rightfully belong to the corporation for themselves.

Fair Dealing
Transactions involving directors must be fair to the corporation.

No Competing Interests
Directors should avoid engaging in businesses that directly compete with the corporation.

Act in Good Faith
Loyalty requires honesty, integrity, and acting in the corporation’s best interest, not just avoiding conflicts.
