First Wind files for $450 mln IPO in Class A shares

July 31 (Reuters) - First Wind Holdings Inc filed with U.S. regulators on Thursday to raise up to $450 million in an initial public offering of Class A common stock.

The Newton, Massachusetts-based company told the U.S Securities and Exchange Commission in a preliminary prospectus that Credit Suisse, Goldman, Sachs & Co and JPMorgan were underwriting the IPO.

The filing did not reveal how many shares the company planned to sell or their expected price. The wind energy company intends to list its common stock on Nasdaq under the symbol "WNDY". (Reporting by Nivedita Bhattacharjee in Bangalore; Editing by Sayantani Ghosh)
