Facts

Plaintiff, a longtime stockholder, former director, and former secretary of Kohler Co., decided in February 1953 to sell his shares quickly and informed Herbert V. Kohler that he needed to do so. The company used accountant Paul F. Johnson as an intermediary, and Johnson sent plaintiff statistical projections of stock value based on comparative data from competitor companies; plaintiff used that data in negotiating and ultimately sold his shares to the company at $115 per share. Plaintiff later claimed defendants failed to disclose material information about the company's pension accounting, a 1952 worksheet projection, and a 1952 tax refund that would have shown a higher value. The financial data actually provided to plaintiff was concededly accurate, and the company's books reflected the accounting treatments and 1952 items at issue.

Issue

Did Kohler Co. and its insider-related agents violate Section 10(b) and Rule 10b-5 by failing to disclose additional information about pension accounting, 1952 financial projections, and a tax refund when purchasing plaintiff's stock? More broadly, what disclosure duties do corporate insiders owe when buying stock from an informed minority holder in a closely held corporation?

Rule

Section 10(b) and Rule 10b-5 impose on corporate insiders and corporations acting through their officers, directors, or agents a duty to disclose material facts affecting stock value that are known by virtue of the insider position, are presumably unknown to the seller, and would reasonably affect the seller's judgment. The statute requires fair play and honest business practices, not merely abstention from common-law fraud, but the duty is limited by the circumstances of the transaction and does not require insiders to volunteer speculative, immaterial, or detail-level information that they reasonably need not believe would influence the seller's decision.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

Pine Harbor Tools, a closely held corporation based in Milwaukee, agreed to repurchase shares from Nina Patel, a former vice president and longtime shareholder who had served on the board for years. Nina insisted on closing within ten days so she could fund another investment in Columbus, and the company provided accurate historical earnings and book-value figures but did not volunteer every accounting detail underlying those figures.

If Nina later sues under Rule 10b-5 claiming the company had a duty to explain all internal accounting details before buying her shares, which is the best answer?

Explanation. The governing rule is contextual. Insiders and the corporation acting through them must disclose material facts known by virtue of the insider position that are presumably unknown to the seller and would reasonably affect the seller's judgment. But the duty is measured by fair and honest business practices under all the circumstances, including the seller's business acumen, familiarity with the corporation, outside advice, and the seller's push for a fast transaction. The majority rejected any unlimited duty to volunteer every detail.
