AIG ANNOUNCES PRICING OF THE SALE OF ORDINARY H SHARES OF PICC PROPERTY AND CASUALTY COMPANY LIMITED NEW YORK, March 30, 2015 — American International Group, Inc. (NYSE: AIG) announced today that it has priced the sale of 256 million ordinary H shares of PICC Property and Casualty Company Limited (PICC P&C) by means of a placing to certain institutional investors. Upon the closing of the placing, which is scheduled for April 2, 2015, and is subject to customary closing conditions, AIG will receive gross proceeds of approximately US$500 million, based upon a purchase price of HK$15.15 (approximately US$1.95) per share. Thereafter, AIG will continue to be the largest holder of PICC P&C H shares, with a position of approximately 1.2 billion shares, representing 8.2 percent of the total issued share capital of PICC P&C. Under the terms of an agreement with the managers of the placing, AIG is restricted from selling any of its remaining ordinary H shares of PICC P&C until July 2, 2015, subject to certain exceptions, including receiving prior consent of certain lead managers of the placing. “AIG is proud of our successful partnership with PICC, which includes our cornerstone investment in the IPOs of both PICC P&C in 2003 and PICC Group in 2012,” said Peter D. Hancock, President and Chief Executive Officer of AIG. “We will continue to seek mutually beneficial opportunities to broaden our strategic relationship with PICC. By monetizing a portion of our PICC P&C investment, we are de-risking our exposure and enhancing AIG’s financial flexibility.” The ordinary H shares have not been and will not be registered under the Securities Act of 1933, as amended (the Securities Act), or any other applicable law, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and any other applicable law. This press release shall not constitute an offer to sell or the solicitation of an offer to buy the ordinary H shares, nor shall there be any sale of the ordinary H shares in any jurisdiction in which such offer, solicitation, or sale would be unlawful.
