On December 10, 2014, the Second Circuit issued an important decision (U.S. v. Newman, No. 13-1837, 2014 WL 6911278 (2d Cir. Dec. 10, 2014)) that will make it more difficult in that Circuit for prosecutors, and most likely the SEC, to prevail on a “tippee” theory of insider trading liability. Characterizing the government’s recent tippee insider trading prosecutions as “novel” in targeting “remote tippees many levels removed from corporate insiders,” the court reversed the convictions of two investment fund managers upon concluding that the lower court gave erroneous jury instructions and finding insufficient evidence to sustain the convictions. The court held, contrary to the government’s position, that tippee liability requires that the tippee trade on information he or she knows to have been disclosed by the tipper: (i) in violation of a fiduciary duty, and (ii) in exchange for a meaningful personal benefit. Absent such knowledge, the tippee is not liable for trading on the information.
