According to regulatory filings with the Securities and Exchange Commission Monday, Renewable Energy Group Inc. (REG) is planning an initial public offering (IPO) of common stock that may approach $150 million, although the filed documents indicate that number is being used solely to calculate the registration fee of the filing.

REG plans to list its shares of common stock under the symbol RWE on the New York Stock Exchange. Credit Suisse Securities is the lead underwriter for the IPO with Goldman Sachs, Banc of America Securities and Thomas Weisel Partners also underwriting the offering.

REG, based in Ralston, Iowa, is one of the leading biodiesel producers in the United States, marketing approximately 78 million gallons of the renewable fuel in 2006.
