Ally Financial, formerly GMAC, said yesterday that it had repaid the last of the debt it had borrowed in response to the financial crisis under a Federal Deposit Insurance Corporation program, the New York Times DealBook blog reported yesterday. Ally, which became a bank holding company after the 2008 crisis, said it had repaid $4.5 billion in debt that was guaranteed by the FDIC under the Temporary Liquidity Guarantee Program. Ally had repaid another $2.9 billion of debt guaranteed under the program on Oct. 30.
