Annual reserve review In the third quarter of 2025 and 2024, we performed our annual reserve review using established industry and actuarial best practices. The annual review resulted in reserve reestimates that increased reserves by $146 million and $58 million in 2025 and 2024, respectively. The reserve reestimates are included as part of claims and claims expense.

The reserve reestimates in 2025 primarily related to new reported information for asbestos claims, new reported claims for environmental and other mass tort claims and increased projections for claims expenses.

The reserve reestimates in 2024 primarily related to new reported information for asbestos related

claims and adverse developments within the other run-off lines.

We believe that our reserves are appropriately established based on available facts, technology, laws, regulations, and assessments of other pertinent factors and characteristics of exposure (e.g., claim activity, potential liability, jurisdiction, products versus non-products exposure) presented by individual policyholders, assuming no change in the legal, legislative or economic environment. However, as we progress with the resolution of disputed claims in the courts and arbitrations and with negotiations and settlements, our reported losses may be more variable.

Segment Results Run-off Property-Liability

Total net reserves as of September 30, 2025, included $773 million or 52% of estimated IBNR reserves compared to $723 million or 51% of estimated IBNR reserves as of December 31, 2024.

Total gross payments were $37 million and $115 million for the third quarter and first nine months of 2025, respectively, compared to $26 million and $88 million for the third quarter and first nine months of 2024, respectively. Payments primarily related to settlement agreements reached with several insureds on large claims, mainly asbestos related losses, where the scope of coverages has been agreed upon. The claims associated with these settlement agreements are expected to be substantially paid out over the next several years as qualified claims are submitted by these insureds. Reinsurance collections were $9 million and $25 million for the third quarter and first nine months of 2025, respectively, compared to $5 million and $31 million for the third quarter and first nine months of 2024, respectively.
