GMAC Financial Services — which controls the nation's fifth largest residential servicer — says it's "business as usual" at the company even though one of its owners, General Motors, filed for bankruptcy protection on Monday.

A GMAC spokeswoman stressed that "we have no intention of filing for bankruptcy," adding that GM owns only 10% of the financial services company. GMAC is a bank holding company that a few months ago completed a large restructuring with its bondholders.

Hedge fund giant Cerberus Capital owns 22% of GMAC with the U.S. Treasury owning a large piece as well because of a $5 billion TARP investment. Asked if GM might sell its stake in GMAC, the spokeswoman declined to comment.
