Reward for running AIG into the ground? A cool $1 billion

Yes, billion. Not million, BILLION.

Of course, Maurice "Hank" Greenberg's ill-gotten gains were worth $20 billion when he left the firm in 2005, but what's a few billion among friends?

CEO Maurice "Hank" Greenberg intends to sell his AIG stock, according to a regulatory filing on Thursday.

Greenberg, who ran AIG for nearly four decades, said he will sell stock in the open market, and that the sales may "materially" decrease the holdings that he controls, according to the filing with the U.S. Securities and Exchange Commission.

Greenberg, through a personal stake, family trust and companies that he controls, owns roughly 11 percent of AIG's stock, making him its largest shareholder before AIG agreed to a federal bailout that will give government 80 percent ownership.
