American International Group, Inc.  and Subsidiaries Survival Ratios-Asbestos and Environmental The following table presents AlG's survival ratios for asbestos and environmental claims for year-end 2006,2005 and 2004.
The survival ratio is derived by dividing the year end carried loss reserve by the average payments for the three most recent calendar years for these claims.
Therefore, the survival ratio is a simplistic measure estimating the number of years it would be before the current ending loss reser ves for these claims would be paid off using recent year average payments.
The December 31, 2006 survival ratio is lower than the ratio at December 31,2005because the more recent periods included in the rolling average reflect higher claims payments.
Many factors, such as aggressive settlement procedures, mix of business and level of coverage provided, have a significant effect on the amount of asbestos and environmental reserves and payments and the resultant survivalratio.
Thus, caution should be exercised in attempting to deter- mine reserve adequacy for these claims based simply on this survival ratio.
AlG's survival ratios for asbestos and environmental claims, separately and combined were based upon a three-year average payment.
These ratios for the years ended December 31,2006,2005 and 2004 were as follows:
