Evaluation Methodology Chubb segmented its defendant policyholders into two groups Traditional defendant policyholders (Tiers 1 & 2) Those engaged in asbestos mining, manufacturing and building products industries Peripheral defendant policyholders (Tiers 3 & 4) Those who manufactured, distributed, or installed an asbestos-containing product or who owned or operated a facility where asbestos products were present 2008AsbestosSlides12909

Exposure Analysis Within these policyholder categories: All Tier 1 & 2 accounts and Tier 3 & 4 accounts with Chubb incurred losses of at least $5M or judged to have high potential exposure were evaluated individually. Claimant information and available coverage were reviewed for each defendant policyholder, including terms of coverage, policy limits and aggregate limits. Tier 3 & 4 accounts not individually evaluated were analyzed in the aggregate using statistical techniques. Factors considered include available coverage, claimant count, report year, bankruptcy, coverage dispute and case reserve amount. Future claims from unknown defendant policyholders were estimated based on claim reporting patterns and projected claim severities. 2008AsbestosSlides12909
