Basic Inc. v. Levinson
Citation: 485 U.S. 224 (Supreme Court, 1988)
Facts
Basic Incorporated publicly denied being engaged in merger negotiations with Combustion Engineering on three occasions while negotiations were in fact ongoing. When the merger was announced, Basic’s stock price jumped significantly. Investors who sold their shares during the period of denials sued under Rule 10b-5, claiming they were damaged by Basic’s misrepresentations. The primary legal questions were: (1) when do merger discussions become “material” requiring disclosure, and (2) how can investors in an open-market class action establish the reliance element of a 10b-5 claim.
Issue
(1) What standard governs the materiality of preliminary merger discussions? (2) May investors satisfy the reliance element of a Rule 10b-5 class action through the “fraud on the market” theory?
Holding
The Supreme Court held: (1) merger discussions are material if a reasonable investor would consider them important — applying the “probability times magnitude” balancing test; and (2) investors may rely on a rebuttable presumption of reliance based on the fraud-on-the-market theory.
Rule
Materiality: a fact is material if there is a substantial likelihood that a reasonable investor would consider it important in deciding whether to buy or sell. For contingent events like merger negotiations, courts weigh the probability that the event will occur against the magnitude of the event if it does occur. Reliance: In an efficient market, the price of a publicly traded security reflects all publicly available information. A misrepresentation that is incorporated into the market price therefore defrauds all market participants who trade at that price, even if they did not directly read the misrepresentation. This presumption is rebuttable by evidence that the misrepresentation did not affect the price, that the market was not efficient, or that a particular plaintiff traded on non-price information.
Significance
Basic v. Levinson is one of the two or three most important securities fraud cases ever decided. Its fraud-on-the-market doctrine made large securities class actions feasible by eliminating the need for each individual investor to prove they personally relied on a misrepresentation — a showing that would be impossible for open-market purchasers. The decision is contested both legally (see Halliburton I and II, where the Court preserved but narrowed the doctrine) and economically (because it assumes markets are efficient, which behavioral economists dispute). The materiality test for preliminary negotiations is also widely applied.
