On April 12, 2024, the U.S. Supreme Court issued an important decision in the case of Macquarie Infrastructure Corp. v. Moab Partners, L.P., No. 22-1165. Justice Sotomayor, writing for a unanimous Court, ruled that “pure omissions are not actionable under Rule 10b-5(b).” In other words, a pure omission (i.e., where a speaker says nothing) cannot support a private claim under Section 10(b) of the Securities Exchange Act of 1934 (the “Exchange Act”) and Rule 10b–5, even if such an omission could constitute a violation of Item 303 of Regulation S-K (“Item 303”).

All too often the task of procuring and renewing D&O insurance at a portfolio company is assigned to the portfolio company’s CFO or Controller, who employs an insurance broker to find the best price for the amount of coverage deemed appropriate by the broker. When such insurance is procured and thereafter renewed, the CFO/Controller simply reports to the board the fact of the procurement/renewal and few questions about the terms of coverage are discussed at the board level. This can be a big mistake.
