Summary: written with AI from the case record.

What it's about
The Court rejected the Ninth Circuit’s rule that the deadline pauses until an insider files a disclosure, wiped out that ruling (vacated it), and sent the case back (remanded); the justices were evenly divided on whether the deadline can otherwise be extended.
Section 16(b) measures its two-year period from the date the profit was realized.
Question presented
Is the two-year time limit for bringing an action under Section 16(b) of the 1934 Securities Exchange Act subject to tolling, and if so, does tolling continue even after the receipt of actual notice of the facts giving rise to the claim?
What the Court decided
Holding
Even assuming that the 2-year period can be extended (a question on which the Court is equally divided), the Ninth Circuit erred in determining that it is tolled until a §16(a) statement is filed. The text of §16(b)—which starts the clock from “the date such profit was realized,” §78p(b)—simply does not support the Whittaker rule. The rule is also not supported by the background rule of equitable tolling for fraudulent concealment. 638 F. 3d 1072, vacated and remanded.
- Result
- Vacated
The Court's reasoning
Section 16(b) starts the two-year clock on the date the profit was realized, the Court said, so it does not support pausing the deadline until an insider files a Section 16(a) statement. The usual rule for pausing deadlines when facts are fraudulently concealed did not support that rule either.
The vote
What's next
The case returns to the Ninth Circuit for further proceedings under the Supreme Court’s ruling.
