"When Do Hedge Fund Managers Have a Duty to Disclose Material, Nonpublic Information?" authored by Richards Kibbe & Orbe attorneys Brian S. Fraser and Tamala Newbold was published by The Hedge Fund Law Report in the November 19, 2009 edition. This article, the first of a two-part series, discusses the duty to disclose material nonpublic information (or refrain from trading) and the differences between the Federal securities laws and New York common law on that issue, in particular, the "superior knowledge" trigger for the duty to disclose under New York law which has no Federal counterpart.
