Four years after facing the possibility of its own demise, General Motors is free of the controversial government ownership that saved the Detroit automaker in 2009.

"It was an unambiguous success," says Steven Rattner, who headed the Obama Administration's Auto Task Force.

The task force shepherded GM through an unprecedented 42-day bankruptcy.

The U.S. Treasury announced Monday it had sold the last of its stock in GM, at a loss of $10.5 billion.
