Were AIG's troubles not well underway by 2005 even if they weren't public knowledge yet? Also if memory serves he was forced out over allegations of illegality in a shady deal AIG made to secretly borrow money from a subsidiary of Berkshire Hathaway to make it look like AIG was in a stronger financial position than they actually were. Also Wikipedia says he was forced out by the AIG board.
