Current report — wording carried from elsewhere

During the third quarter of 2024, the Company completed its annual in-depth asbestos claim review. While the latest available government data continue to reflect a declining trend in deaths caused by mesothelioma, the number of policyholders with open asbestos claims was relatively flat compared to 2023. Net asbestos paid loss and loss adjustment expenses in 2024, 2023 and 2022 were $282 million, $212 million and $245 million, respectively. Payments on behalf of these policyholders continue to be influenced by the factors described above, including an increase in severity for certain policyholders and a high level of litigation activity in a limited number of jurisdictions where individuals alleging serious asbestos-related injury, primarily mesothelioma, continue to target defendants who were not traditionally sued and/or primary targets of asbestos litigation. The completion of the analyses described above and the annual review in the third quarters of 2024, 2023 and 2022 resulted in $242 million, $284 million and $212 million increases, respectively, to the Company’s net asbestos reserves. In each year, the reserve increases were primarily driven by increases in the Company’s estimate of projected settlement and defense costs related to a broad number of policyholders. The increase in the estimate of projected settlement and defense costs primarily resulted from payment trends that continue to be higher than previously anticipated due to the continued high level of mesothelioma claim filings and the impact of the current litigation environment surrounding those claims discussed above. The 2023 charge also included an additional increase to strengthen the Company’s carried reserve position relative to the range of reasonable estimates.

In the third quarter of 2023, the Company completed its annual in-depth asbestos claim review, including a review of policyholders with open claims and litigation cases for potential product and “non-product” liability. The number of policyholders with open asbestos claims was relatively flat compared to 2022, while net asbestos payments were slightly lower than 2022. Payments on behalf of these policyholders continue to be influenced by an increase in severity for certain policyholders and a high level of litigation activity in a limited number of jurisdictions where individuals alleging serious asbestos-related injury, primarily mesothelioma, continue to target defendants who were not traditionally primary targets of asbestos litigation.
