AIG Issues Initial Estimate of Losses from Hurricane Katrina.

NEW YORK -- American International Group, Inc. (AIG) has issued an initial estimate of its total expected losses relating to third quarter catastrophe events, principally Hurricane Katrina, totaling approximately $1.1 billion after-tax.

AIG estimates that its total after-tax insurance related losses, net of reinsurance recoverables, to be recorded in the third quarter, will be approximately $900 million. In addition, AIG expects to record an after-tax charge of approximately $170 million relating to reinstatement premiums. The $900 million estimate includes AIG's Domestic Brokerage Group (including Lexington Insurance Company), Domestic Personal Lines business, Foreign General operations, Domestic Life Insurance operations, AIG's prorated share of losses from its majority ownership in Transatlantic Holdings, Inc. and Lloyd's Syndicate 1414 (Ascot), and AIG's minority investments in Allied World Assurance Co., Ltd and IPC Holding Ltd. In addition to insurance related losses, AIG estimates that it will incur approximately $60 million after-tax in non-insurance losses, primarily from consumer finance operations, investment portfolio impairments and AIG owned and leased facilities.

These preliminary estimates involve the exercise of considerable judgment and reflect a combination of ground-up evaluations, modeled numbers and industry loss estimates. Due to the unprecedented nature of this event, including legal and regulatory uncertainty, an inability to access portions of the affected areas, the complexity of factors contributing to the losses and the preliminary nature of the information used to prepare these estimates, there can be no assurance that AIG's ultimate costs associated with this event will not exceed these estimates.

AIG President and Chief Executive Officer Martin J. Sullivan said, "Our top priorities continue to be to respond to our customers who have sustained a devastating loss of life and property caused by Hurricane Katrina and its aftermath and ensure the well being of our employees. Our employees in the region, including many who themselves suffered as a result of Katrina, are working diligently to provide immediate financial assistance to customers who have experienced losses. Katrina's wake of destruction is unprecedented, but AIG's financial strength and claims management expertise enable us to respond to a catastrophe of this magnitude. Our hearts go out to all who have suffered from this tragic event."
