The market for initial public offerings on U.S. exchanges improved significantly in 2010. There were 150 U.S. IPOs that raised a total of $34.5 billion in the first 11 months of the year. That compares favorably to 64 in 2009 and 51 in 2008. Last year’s two largest IPOs came in the fall: the $23.1 billion IPO of General Motors Company, and American International Group, Inc.’s $20.5 billion spin-out of two-thirds of AIA Group, Limited.

Below, we list the law firms that worked on the GM and AIA deals as well as three other high-profile IPOs of 2010: KKR & Co. L.P., Tesla Motors Inc., and Oasis Petroleum Inc. All underwriters are listed in the order and with the name given in the prospectus and are based in New York unless otherwise noted.—David Marcus
