Q1 2023 Reinsurance Update

Catastrophe Reinsurance Programs

Northbrook, IL, May 3, 2023 - We completed the placement of our 2023-2024 Nationwide Excess Catastrophe Reinsurance Program (1) that provides reinsurance protection to the Allstate Protection businesses of The Allstate Corporation (NYSE: ALL), the National General Reciprocal Excess Catastrophe Program and the Kentucky Earthquake Excess Catastrophe Reinsurance Contract. The Florida Excess Catastrophe Program and the National General Lender Services Program will be completed in the second quarter of 2023.

The catastrophe reinsurance program is part of our catastrophe management strategy, which is intended to provide our shareholders with an acceptable retuon the risks assumed in our personal lines business, reduce earnings variability, and provide protection to our customers. Our current catastrophe reinsurance program supports our risk tolerance framework which utilizes a modeled 1-in-100 annual aggregate limit for catastrophe losses from hurricanes, earthquakes and wildfires of $2.50 billion, net of reinsurance.

Allstate's catastrophe reinsurance program materially reduces our exposure to wind, earthquake, and wildfire losses. We employ a multi-year approach to placing reinsurance coverage to lessen the amount of reinsurance being placed in the market in any one year. Claim adjustment fees are indemnified as a percentage of ultimate net loss and are included within each contract's reinsurance limit.

The reinsurance agreements have been placed in the traditional reinsurance and Insurance-Linked Securities ("ILS") markets. In doing so, we consider a number of factors including coverage, cost, terms, and the period of protection. All reinsurers participating on our program have an A.M. Best insurance financial strength rating of A- or better, except one, that is not rated by A.M. Best. Additionally, all reinsurance agreements placed in the ILS markets are collateralized.

The total cost of our property catastrophe reinsurance programs, excluding reinstatement premiums, was $219 million and $144 million in the first quarter of 2023 and 2022, respectively. The total cost of our catastrophe reinsurance program during 2022 was $788 million.
