Largest IPO by GM

US  based auto maker General Motors increased the size of its planned initial public offering (IPO) that opened on 18 November 2010 by nearly a third, bringing the total to as much as $20.4 billion, which would be the largest first day stock sale on record. At the lower end of the price range, GM would sell $19.9 billion in common and preferred shares. A large part of the additional shares sold on 18 November came from the US Treasury. The US Treasury received 60.8% of the company's common shares in return for 2009 $50 billion bailout that was needed to see the company through its bankruptcy process. Through the IPO GM will have repaid nearly $22 billion of the bailout. Whether or not the taxpayers will get the remaining $28 billion will be determined by the price GM gets on the sale of remaining shares.

The largest IPO in history was the $19.2 billion raised in Hong Kong by the Agricultural Bank of China in July 2010. The largest U.S. IPO was the $17.9 billion raised by Visa in March 2008.
