By Sarah Skidmore, AP Business ReporterTwo affiliates of SAC Capital Advisors, the hedge fund run by billionaire Steven Cohen, will pay more than $614 million in what federal regulators are calling the largest insider trading settlement ever. The Securities and Exchange Commission charged CR Intrinsic Investors with insider trading in 2012, alleging that portfolio manager Mathew Martoma illegally obtained confidential details about an Alzheimer's drug trial from a doctor before the final results went public and traded on that information. The SEC said Friday that the fund agreed to pay more than $600 million to settle the charges. The parties neither admit nor deny the charges. The SEC's complaint alleged that Sidney Gillman, a doctor who moonlighted as a medical consultant, tipped drug safety data and negative drug trial results to Martoma two weeks before developers Elan ( ELN) and Wyeth ( WYE) made those results public in 2008. Martoma and CR Intrinsic then caused several hedge funds to sell more than $960 million in Elan and Wyeth securities in a little more than a week. Regulators added SAC Capital Advisors and four hedge funds managed by CR Intrinsic and SAC Capital as defendants, saying they each received ill-gotten gains from the scheme.
