GMAC Financial Services will immediately resume auto financing for a broader spectrum of U.S. customers as a result of expanded access to funding as a bank holding company. The co will modify its credit criteria to include retail financing for customers with a credit bureau score of 621 or above, a significant expansion of credit compared to the 700 minimum score put in place two months ago. GMAC's application to become a bank holding company was approved by the Federal Reserve Board of Governors on Dec. 24, 2008. The co also announced that it received an investment from the U.S. Treasury Department as part of the Troubled Assets Relief Program. At this time, GMAC will not finance higher risk transactions characterized by a credit bureau score of 620 or below. The co will utilize both GMAC Bank and funding from other sources to resume its traditional spectrum of prime-based credit, appropriately pricing for risk and requiring down payments where necessary.
