The Supreme Court has outlined limits in securities liability concerning the omission of material facts in the recent Macquarie Infrastructure Corp. v. Moab Partners case.
The case revolved around Rule 10b-5 of the Securities and Exchange Commission, a regulation that provides private cause of action when a company neglects to disclose essential facts during a securities transaction which would render their statements misleading. However, the complexity arises in the circumstances where the omitted information does not make the company’s statements misleading.
Specifically, Macquarie Infrastructure had an obligation as per an SEC regulation to disclose material information about the company in its periodic filings with the SEC. One of its principal assets, storage terminals for fuel oil, is affected by a United Nations rule aiming to phase out fuel oil high in sulfur content. According to the SEC’s Regulation S-K (Item 303), the firm should disclose such material information.
Investors, including Moab partners, argued that Macquarie’s silence on the issue as required by Item 303 violated Rule 10b-5. While the lower courts sided with the investors, the Supreme Court, in a unanimous ruling delivered by Justice Sonia Sotomayor, disagreed.
The Supreme Court’s ruling divides the ‘omission’ issue into ‘pure omissions’ and ‘half-truths’. ‘Pure omissions’ refer to situations where nothing is stated, and the silence doesn’t carry any particular meaning, whereas ‘half-truths’ are cases where the truth is incomplete due to the absence of gravely significant qualifying information.
Justice Sotomayor clarified that Rule 10b-5 doesn’t outlaw pure omissions, as it hinges on disclosing information needed to ensure clarity and completion of statements already made. The decision makes it apparent that the SEC’s Rule 10b-5 necessitates first identifying affirmative claims before deciding if additional facts are needed to prevent those statements from becoming misleading.
This judgement brings a level of resolution to a dispute across federal courts of appeals. However, its broader implications remain to be seen, depending on the interpretation and application by legal professionals in future cases. You can read the full case details on the SCOTUS blog here.
