Troubled insurer American International Group Inc., now 80% owned by U.S. taxpayers, spent the weekend deflecting mounting criticism of how government funds have been funneled to various banks and used to pay employee bonuses at the business unit that almost sank the company.

After calls for more transparency, AIG disclosed Sunday that roughly two-thirds of the $173.3 billion in federal aid it received has been paid out to trading partners such as banks and municipalities in the U.S. and abroad.

The disclosures came as AIG was lambasted for about $450 million in bonus payments planned for employees at a business unit that lost $40.5 billion last year. The unit's woes pushed the company to near-collapse, forcing the government bailout.

The disclosures highlighted the increasingly close but uncomfortable relationship between AIG and the U.S. government, which six months ago was a restless creditor and now has little choice but to be a patient ally.

"Something is terribly wrong with this picture, and the reckless behavior at AIG must stop immediately," said Rep. Elijah Cummings (D., Md.), in a statement Sunday. He called on AIG's government-appointed chief executive, Edward Liddy, to resign over the bonus-payments issue.
