Does GM Have Any Responsibility To The Taxpayer To Raise Stock Prices?

The U.S. Treasury Department boosted its estimate of government losses in the $85 billion auto bailout by $170 million.

In the government's latest report to Congress this month, the Treasury upped its estimate to $23.77 billion, up from $23.6 billion.

Last fall, the government dramatically boosted its forecast of losses on the rescues of General Motors Co., Chrysler Group LLC and their finance units from $14 billion to $23.6 billion.

Much of the increase in losses is due to the sharp decline of GM's stock price over the last six months.
