Rajaratnam and Needham colleagues Krishen Sud, Gary Rosenbach and Ari Arjavalingam formed Galleon Group in January 1997. By the end of that year, they were managing $830 million, much of it from technology company executives Rajaratnam had gotten to know throughout his career, according to "The New Investment Superstars."
Rajaratnam's case was the most prominent amid a widespread U.S. crackdown on insider trading. In New York, the Galleon probe and related cases have led to more than 40 arrests since 2009 and guilty pleas from about 30 of the accused, including Chiesi. A related case against former Galleon trader Zvi Goffer is scheduled for trial this month.
Among others charged are executives affiliated with Primary Global Research LLC, a Mountain View, California-based networking firm that links investors with industry experts who work for public companies.
The case is U.S. v. Rajaratnam, 1:09-cr-01184, U.S. District Court, Southern District of New York (Manhattan).
