Mesa Petroleum, led by T. Boone Pickens, launched a hostile takeover bid for Unocal Corporation by proposing a tender offer for approximately 37% of Unocal's shares. In response, Unocal's board, fearing that the offer was inadequate and coercive, devised a defensive strategy: a selective self-tender offer. This involved purchasing shares back from all shareholders except Mesa. The plan was intended to dilute Mesa's holdings and prevent it from gaining control without paying the non-tendering shareholders an adequate price. However, this selective approach was challenged by Mesa, arguing it was discriminatory and undermined shareholder equality.
Whether the defensive measures employed by Unocal were reasonable and proportional to the threat posed by Mesa Petroleum's takeover bid?
Directors' decisions in response to a takeover offer must be reviewed under the two-prong Unocal test: (1) the directors must demonstrate that they had reasonable grounds for believing that a threat to corporate policy and effectiveness existed, and (2) the defensive measure must be proportional to the threat posed.
The court held that Unocal's defensive strategy was legal, as it met both prongs of the Unocal test. The board had acted with reasonable grounds to perceive a threat to the corporation, and their response was proportional to the perceived threat.
The Delaware Supreme Court reasoned that the board's determination that Mesa's offer was inadequate and coercive was reasonable. The selective self-tender offer was proportionate because it addressed the specific threat posed by Mesa's attempt to acquire control without offering a fair value to all shareholders. The court emphasized the board's role in protecting the corporate enterprise and its stockholders from harm, asserting that directors are entitled to consider the process by which control might change and its impact on shareholders generally.
This case is pivotal for students of corporate law as it articulates the standards under which defensive tactics in hostile takeovers will be evaluated. The 'Unocal test' introduced in this case is crucial for understanding how courts balance the protection of shareholder value with the discretion afforded to boards of directors.
Unocal v. Mesa Petroleum set a significant direction in corporate governance and legal scrutiny of board actions, introducing the Unocal test as a gold standard for evaluating defensive moves in hostile takeovers. This case underscores the delicate balance boards must maintain between exercising their discretion and acting in shareholder interests, providing a structured lens through which such decisions are evaluated. For students of corporate law, Unocal serves as a foundational case that elucidates the principles of fair corporate governance while asserting the critical role that boards play in safeguarding not just shareholder interests, but the broader integrity and continuity of the corporation.
