"will not substitute its own notions of what is or is not sound business judgment" if "the directors of a corporation acted on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the company." Duty of care and duty of loyalty Although a distinct common law concept from duty of care, duty of loyalty is often evaluated by courts in certain cases dealing with violations by the board. While the business judgment rule is historically linked particularly to the duty of care standard of conduct, shareholders who sue the directors often charge both the duty of care and duty of loyalty violations. This forced the courts to evaluate duty of care (employing the business judgment rule standard of review) together with duty of loyalty violations that involve self-interest violations (as opposed to gross incompetence with duty of care). Violations of the duty of care are reviewed under a gross negligence standard, as opposed to simple negligence. Consequently, over time, one of the points of review that has entered the business judgment rule was the prohibition against self-interest transactions. Conflicting interest transactions occur when a director, who has a conflicting interest with respect to a transaction, knows that she or a related person is (1) a party to the transaction; (2) has a beneficial financial interest in, or closely linked to, the transaction that the interest would reasonably be expected to influence the director's judgment if she were to vote on the transaction; or (3) is a director, general partner, agent, or employee of another entity with whom the corporation is transacting business and the transaction is of such importance to the corporation that it would in the normal course of business be brought before the board. Standard of review The following test was constructed in the opinion for Grobow v. Perot, 539 A.2d 180 (Del. 1988), as a guideline for satisfaction of the business judgment rule. Directors in a business should: act in good faith; act in the best interests of the corporation; act on an informed basis; not be wasteful; not involve self-interest (duty of loyalty concept plays a role here). Rationale Under the Delaware General Corporation Law, the business judgment rule is the offspring of the fundamental principle, codified in Del. Code Ann. tit. 8, § 141(a), that the business and affairs of a Delaware corporation
