Even though he's claiming he's innocent of insider trading charges, billionaire Raj Rajaratnam is liquidating his Galleon Group hedge fund and preparing to shut it down. In a letter sent to investors, Rajaratnam wrote, "I want to reassure investors of the liquidity of our funds and assure Galleon employees that we are seeking the best way to keep together what I believe is the best long/short equity team in the business. I want to reiterate that I am innocent of all the charges."
