NEW YORK (Bloomberg) — American International Group Inc. has used $90.3 billion of a US government credit line since it was bailed out last month, an amount exceeding the size of the original loan meant to save the insurer.

AIG may need more than the $122.8 billion now available to the New York-based insurer, chief executive officer Edward Liddy said last week. The company, which agreed on September 16 to turn over majority control to the US in exchange for an $85 billion loan, got access to an additional $37.8 billion this month. AIG's latest balance was revealed yesterday by the New York Federal Reserve, and is up from $82.9 billion a week ago.

"This emphasises the uncertainty for anyone trying to put a number" on AIG's cash needs, said Bill Bergman, an analyst at Morningstar Inc. in Chicago. The financial-products unit that caused most of the firm's losses "is a big black hole".

Liddy, the former Allstate Corp. CEO appointed by the government to run AIG last month, is selling businesses including US life insurance, plane leasing and consumer finance to repay the loan. He named Paula Rosput Reynolds yesterday to lead the restructuring six months after she arranged the $6.2 billion sale of Safeco Corp., AIG said.
