CINCINNATI -- American Financial Group, Inc. (NYSE:AFG)(NASDAQ:AFG) today announced that its Board of Directors has authorized the repurchase of up to an additional 5 million shares of the Company's outstanding common stock. This authorization is in addition to the 1 million shares remaining from the Board's previous authorization in March 2004. AFG intends to repurchase shares from time to time by means of open market purchases and privately negotiated transactions at prevailing market prices. The number of shares purchased, if any, will be dependent upon market conditions. The Company currently has approximately 116 million shares of common stock outstanding.

Pursuant to the Board's previous authorization, AFG has repurchased 3.1 million shares at an average price of $27.08 per share during the third quarter of 2007. This brings total purchases during the year to 4 million at an average price of $28.53. "This additional authorization reflects the Board of Directors' continued confidence in the Company's prospects and commitment to enhancing shareholder value," said S. Craig Lindner and Carl H. Lindner III, AFG Co-Chief Executive Officers.
