A sale within the next several months would almost certainly mean U.S. taxpayers will take a loss on their $50 billion rescue of the Detroit auto maker in 2009.

To break even, the U.S. Treasury would need to sell its remaining stake—about 500 million shares—at $53 apiece. GM closed off 27 cents a share at $29.97 in 4 p.m. trading Monday on the New York Stock Exchange, hitting a new low since its $33-a-share November initial public offering.

“Planning for the sale of our remaining GM stock is still at an early stage, and the IPO lock-up does not expire until late May,” a Treasury spokesperson said. “At that point, we will consider all of our options, based on our twin goals of protecting taxpayers’ interests and exiting as soon as practicable.”
