GM logoThe United States government still has a vested interest in the success of General Motors. In fact, the U.S. government is sitting on 500 million shares, which are currently worth about $14.3 billion dollars based on current prices. There is a problem, though, as the U.S. Treasury Department was hoping to get a larger pile of green for its GM investment.

When GM initially hit the stock market with its IPO, the per-share price was $33. Now, it's down around $28.78, which doesn't sound like much of a drop, but across 500 million shares, that figure represents a massive hit to the wallet.

For the time being, BusinessWeek reports that the U.S. government is going to sit on the stock in the hopes that it climbs back to IPO levels.
