Allstate Announces September and Third Quarter 2023 Catastrophe Losses, Implemented Rates and Prior Year Reserve Reestimates

The Allstate Corporation (NYSE: ALL) today announced estimated catastrophe losses for the month of September of $317 million or $250 million, after-tax.

September month catastrophe losses include 17 events estimated at $357 million, with approximately 80% of the losses related to two wind and hail events, partially offset by favorable reserve reestimates for prior events. Total catastrophe losses for the third quarter were $1.18 billion, pre-tax.

Unfavorable prior year reserve reestimates, excluding catastrophes, totaled $166 million in the third quarter, with approximately $84 million related to Allstate Protection and $82 million attributable to the Run-off Property-Liability annual reserve review. Allstate Protection was driven by $95 million related to personal auto for the National General brand. All other Allstate Protection reserve reestimates were favorable $11 million.

During the month of September, the Allstate brand implemented auto rate increases of 4.5% across 9 locations, resulting in total brand premium impact of 0.9%.

“Allstate continued to implement significant auto and homeowners insurance rate actions as part of our comprehensive plan to improve profitability. Since the beginning of the year, rate increases for Allstate brand auto insurance have resulted in a premium impact of 9.5%, which are expected to raise annualized written premiums by approximately $2.46 billion, and rate increases for Allstate brand homeowners insurance have resulted in a premium impact of 9.5%, which are expected to raise annualized written premiums by approximately $971 million. Implemented rate increases and inflation in insured home replacement costs resulted in a 12.4% increase in homeowners insurance average gross written premium in September 2023 compared to the prior year,” said Jess Merten, Chief Financial Officer of The Allstate Corporation.
