Zahn v. Transamerica Corp., 162 F.2d 36 (3d Cir. 1947)
Zahn v. Transamerica is a cornerstone corporate law decision illustrating the limits equity imposes on the formal contractual rights found in a corporate charter.
May a controlling shareholder and the directors, consistent with their fiduciary duties, exercise an otherwise valid charter power to redeem preferred stock at a fixed call price when they do so with knowledge of and in anticipation of an imminent liquidation or asset sale, for the purpose and effect of eliminating the preferred stock's chartered right to participate in the liquidation surplus, thereby diverting value to the common stock class controlled by the controller?
Under Delaware corporate law, directors and controlling shareholders owe fiduciary duties of loyalty and fairness to all stockholders. Corporate powers and rights conferred by statute or charter, including redemption rights, must be exercised in good faith for proper corporate purposes and may not be used inequitably to benefit one constituency—particularly the controller's class of stock—at the expense of another. Where a controlling shareholder stands on both sides of a transaction or employs control to reallocate value between classes, the controller bears the burden to demonstrate the transaction's entire or intrinsic fairness. Equity will not permit corporate actors to achieve indirectly (through timing or form) what would be impermissible directly—i.e., the expropriation of another class's chartered rights and value.
The court held that exercising the redemption right to call the preferred stock on the eve of an anticipated liquidation or asset sale, with the purpose and effect of stripping the preferred of its chartered participation in the liquidation surplus so that the common stockholders (principally the controller) would capture that value, was an inequitable breach of fiduciary duty. The preferred holders were entitled to equitable relief measured by the value they would have received had the redemption not been used to frustrate their liquidation and participation rights, with appropriate distinctions for holders who had or had not surrendered their certificates.
Zahn is a foundational case on the fiduciary duties owed to different classes of stock—especially preferred versus common—and on the equitable limits to the exercise of contractual rights in corporate charters. It teaches that directors and controllers cannot exploit charter-authorized tools (like redemptions) to reallocate corporate value opportunistically when a transformative transaction is imminent. The case anchors modern Delaware doctrine that even valid corporate acts may be enjoined or unwound if undertaken for inequitable purposes, and it foreshadows later entire-fairness jurisprudence in controller conflicts. For students, Zahn sharpens the interplay between contract (certificate terms defining preferred rights) and fiduciary duty (the fairness overlay governing how those rights are exercised in context).
