American International Group Inc. has been repaid the $5 billion it contributed to a fund created in 2008 as part of the insurer's U.S. rescue, the Federal Reserve Bank of New York said. Sales of mortgage-related assets held in the Maiden Lane III portfolio enabled the repayment of New York-based AIG's stake and interest, the district bank said in a statement on its website today. AIG will get one-third of the profit from further asset sales, with the New York Fed getting the rest.
