General Motors says its common stock will sell for $33 per share when its initial public offering takes place tomorrow. The IPO, one of the largest in history, brings the US government closer to getting back part of the $50 billion it gave GM last year. The government will sell 412 million shares and get $13.6 billion, leaving it with about 500 million shares, or about 33% of GM. It would have to sell them for $53 a share, or $26.4 billion, for taxpayers to get back their $50 billion back. (More General Motors stories.)
