The U.S. Treasury Department said it expected to sell its remaining shares of General Motors by the end of the year, a plan that may leave taxpayers with a shortfall of about $10 billion on the automaker's 2009 bailout.

Treasury on Thursday said it had completed the sale of 70.2 million shares of GM stock and to date had recouped $38.4 billion from the $49.5 billion taxpayer-funded rescue of the Detroit company.

At current prices, Treasury would recoup another $1.2 billion from its remaining stake, bringing its total recovery to $39.6 billion.

Analysts have said Treasury's exit from GM would lift the "Government Motors'' stigma from the automaker, which would also be able to begin paying dividends for the first time since the restructured company returned to the market with an initial public offering three years ago.

Treasury's sale of the shares "could lead to the lifting of compensation limitations for GM's key executives,'' said Buckingham Research analyst Joseph Amaturo.
