Full Definition
A fiduciary duty is a legal and ethical obligation requiring a person in a position of trust and confidence to act in the best interests of those they represent—not in their own interests or the interests of third parties. Fiduciary relationships exist in many contexts: corporate directors owe fiduciary duties to the corporation and its shareholders; investment managers owe fiduciary duties to their fund's limited partners; trustees owe duties to trust beneficiaries; attorneys owe duties to their clients. The fiduciary standard is the highest standard of care in law, imposing obligations that go beyond ordinary good faith dealing to require active loyalty, transparency, and skill. In the corporate governance context, directors and officers owe two primary fiduciary duties. The Duty of Care requires directors and officers to make decisions with the diligence, care, and skill that a reasonably prudent person would exercise in similar circumstances—to be informed, to deliberate adequately, and to make decisions that a reasonable person with comparable responsibility would make. The Duty of Loyalty requires directors and officers to prioritize the interests of the corporation and its shareholders over their personal interests or the interests of third parties—to avoid conflicts of interest, disclose material conflicts when they exist, and abstain from transactions where their personal interest conflicts with the corporation's interest. The Business Judgment Rule provides a legal presumption in Delaware and most U.S. states that board decisions made in good faith, with adequate information, and without conflict of interest are immune from judicial review even if the decision proves unwise in hindsight. This protection is essential: without the business judgment rule, directors would be exposed to liability for every business decision that turns out badly, chilling the risk-taking that creates economic value. The business judgment rule protection is lost when directors fail the conditions: acting in bad faith, without adequate information, or in a conflicted self-interest situation—in which case courts apply "entire fairness" review requiring the directors to prove both fair dealing and fair price.
FAQs
What is 'duty of candor' and how does it apply in M&A?
The duty of candor (also called duty of disclosure) is an aspect of the duty of loyalty requiring directors to make accurate and complete disclosure to shareholders when seeking shareholder approval for major transactions—particularly in M&A. When a board recommends that shareholders approve a merger, they must disclose all material information—including fairness opinions, management financial projections, and any conflicts of interest—that shareholders would consider important in voting. Material omissions or misleading statements in proxy materials violate the duty of candor and can invalidate a shareholder vote or expose directors to liability.
Do officers owe the same fiduciary duties as directors?
Yes—officers of a corporation owe the same fiduciary duties as directors (duty of care and duty of loyalty) by operation of state corporate law and common law principles. Officers also typically owe duties under their employment agreements and corporate codes of conduct. The duty of loyalty for officers is particularly important: officers who use their position to take corporate opportunities for personal benefit, disclose confidential corporate information to competitors or investors, or engage in self-dealing transactions violate their fiduciary duty in the same way a conflicted director would. However, officers making business decisions within their scope of authority receive the same business judgment rule protection as directors.
