GM paid back that loan with a mix of cash and stock, as agreed -- in fact, it made the last payments well ahead of schedule. But here's the problem: At least right now, the stock isn't worth enough to fully repay the amount of the loan.

The government says that it would have to get more than $90 a share for its remaining stock to make things whole, but GM stock isn't trading anywhere near that level. In this video, Fool contributor John Rosevear looks at the latest on GM's repayment status and at how much the government is likely to lose on its "investment" in General Motors.
