American International Group (AIG) repaid nearly $1 billion in rescue funds from the Treasury Department Tuesday, the same day that a government office released a report slamming the Federal Reserve for apparent missteps in bailing out the financial institution in 2008.

The company said in a statement that it made the $972-million payment with funds primarily from an escrow account in association with the sale of American Life Insurance Company to MetLife in 2010. The Treasury Department said in a separate statement that the funds would pay back taxpayers by redeeming an equal amount of the department’s equity interests in AIG subsidiary AIA Aurora LLC.

This is the sixth such payment and ups the total amount repaid to approximately $45 billion.

“We continue to make steady progress toward our goal of America’s taxpayers recouping their entire investment in

AIG,” Robert H. Benmosche, AIG president and CEO, said in a statement. “I am confident that AIG’s employees will continue to work hard so we can achieve this goal.”

AIG still owes Treasury – and taxpayers by extension – $8.4 billion for the $182.3 billion in funds it received at the height of the financial crisis.

In tandem with the payment, the Government Accountability Office (GAO) offered a report earlier Tuesday with accusations that the Federal Reserve and its New York district neglected important reporting requirements and overstepped conflict-of-interest policies in making the decision to bail out AIG during the financial crisis.

“While the Federal Reserve Board exercised broad emergency lending authority to assist AIG, it was not required to, nor did it, fully document its interpretation of its authority or the basis of its decisions,” the report said. “For federal securities filings AIG was required to make, FRBNY influenced the company’s filings about federal aid but did not direct AIG on what information to disclose.”

The GAO said that “a series of complex relationships” resulted from the bailout that included advisors with the Fed in New York, AIG counterparties, and a number of others, which the office said may have exposed the central bank to a level risk that it “would not fully identify and appropriately manage.”

AIG’s repayment came on the heels of announcement that BB&T bought up BankAtlantic – a strategic move for the company that also received taxpayer funds in 2008 and repaid the same in 2009.
