From the WSJ:

The U.S. government is likely to inject $2.8 billion to $5.6 billion of capital into the Detroit company, on top of the $12.5 billion that GMAC has received since December 2008, these people said. The latest infusion would come in the form of preferred stock. The government’s 35.4% stake in the company could increase if existing shares eventually are converted into common equity.

Federal officials also are moving to shore up GMAC’s ability to fund its daily operations, with the Federal Deposit Insurance Corp. telling the company Tuesday the agency will guarantee an additional $2.9 billion in debt, according to people familiar with the discussions. The FDIC guarantee will make it easier for the company to sell debt to investors. The FDIC backed $4.5 billion in GMAC-issued debt earlier this year.

We now make a prediction:  GMAC will be the first of many.  Due to cash flow, several more TBTF banks will come back to the bailout trough over the next 6 months…
