India-born ex-Goldman Sachs director Rajat Gupta’s conviction on insider trading charges should not be thrown out as the government provided “overwhelming” proof against him for passing on illegal information in return for “expected potential pecuniary gains,” US prosecutors said. The prosecutors said the IIT and Harvard-educated former McKinsey head, who is serving a two-year sentence, had a “powerful” financial incentive to tip his billionaire hedge-fund operator friend Raj Rajaratnam.

Rajaratnam expected, and Gupta consistently delivered, inside information that Gupta possessed as a corporate insider. For those tips, Gupta clearly expected potential pecuniary gain in return,” the prosecutors said.
