2023 Form 10-KRun-off Property-Liability

Run-off Property-Liability Segment

The Run-off Property-Liability segment includes results from property and casualty insurance coverage that primarily relates to policies written during the 1960s through the mid-1980s. Our exposure to asbestos, environmental and other run-off lines claims arises principally from direct excess commercial insurance, assumed reinsurance coverage, direct primary commercial insurance and other businesses in run-off. We may pursue settlement agreements including policy buybacks on direct excess commercial business when appropriate to improve the certainty of the liabilities. Settlement agreements are negotiated contracts between Allstate and third parties that generally set forth the rights and obligations of the parties, including terms of payment for claims. For additional information on our strategy and outlook, see Part I, Item 1. Business - Strategy and Segment Information.

Underwriting losses in 2023 and 2022 primarily related to our annual reserve review using established industry and actuarial best practices. The annual review resulted in unfavorable reserve reestimates totaling $80 million and $118 million in 2023 and 2022, respectively. The reserve reestimates are included as part of claims and claims expense.

The reserve reestimates in 2023 primarily related to new reported information and defense costs for asbestos and other run-off exposures and higher than expected environmental reported losses. The reserve reestimates in 2022 primarily related to new reported information and defense costs for asbestos and higher than expected reported losses for environmental and other run-off exposures.

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.
