Silicon Valley man pleads guilty in Galleon case A former director of a global management consulting firm pleaded guilty today to securities fraud charges, admitting making $2.6 million by feeding inside stock information to one of America's richest men in history's largest hedge-fund insider trading case. Anil Kumar, 51, of Saratoga, Calif., entered the plea in U.S. District Court in Manhattan in a cooperation deal aimed at strengthening the government's case against billionaire hedge-fund operator Raj Rajaratnam. Rajaratnam reaped $19 million from investments made after Kumar, a former senior partner and director at McKinsey & Co. Inc., fed him tips between March and July 2006 about the acquisition of ATI Technologies Inc. by Advanced Micro Devices Inc., Assistant U.S. Attorney Jonathan R. Streeter said.
