How the Top 25 Insurers Are Ranked
The list is derived from a market share report published by the National Association of Insurance Commissioners (NAIC) in March 2022. Insurers are ranked in descending order based on direct premiums written in 2021 for all lines of property/casualty insurance. The term “direct written premiums” means all policy premiums collected by an insurer during the calendar year without any adjustments for premiums ceded (transferred) to reinsurance companies. The lines of insurance included in the ranking are personal auto, commercial auto,workers’ compensation, medical professional liability, homeowners, and other liability (excluding auto liability). The ranking does not include premiums generated from life insurance policies. The NAIC publishes a separate list of the 25 largest life insurers.
