NEW YORK--(BUSINESS WIRE)--Sept. 13, 2001

American International Group, Inc. (AIG) has issued a preliminary estimate of its total expected losses resulting from Tuesday's terrorist attacks.

Based on information available at this time, AIG's net pretax losses are expected to approximate $500 million.

AIG Chairman M. R. Greenberg said, "We remain intensely focused on providing immediate assistance and relief to those who have suffered losses relating to this enormous national tragedy. Our crisis teams are in place, functioning on a twenty-four hour basis, and they are prepared to process claims.

"It is impossible for any company to precisely estimate total losses at this time. Although AIG's property insurance coverages on the World Trade Center complex are minor, as the world's largest commercial insurer, we expect to receive claims from many insureds across a wide range of coverages. These losses will not impact the solid financial condition of AIG, the strongest insurance and financial services company in world."
