AIG filed suit against the Federal Reserve Bank of New York in January 2013 in order to maintain the former's right to sue Bank of America and other issuers of bad mortgage debt. The specific issue was whether the Federal Reserve Bank of New York transferred $18 billion in litigation claims on troubled mortgage debt through Maiden Lane Transactions, entities created by the Fed in 2008. This transaction, AIG argued, prevented them from recouping losses from insured banks. Owing to events which allowed AIG to proceed in another related case, "AIG Inc. v. Bank of America Corporation LLC", AIG withdrew the Maiden Lane case "without prejudice" on May 28, 2013.
