2021 CA Property & Casualty Market Share

The following reports are for the 2021 Market Share of Property & Casualty Insurers licensed to do business in California. The data are from the National Association of Insurance Commissioner's (NAIC) database, for California licensed companies only. The information is the same as reported on the Exhibit of Premiums and Losses (Statutory Page 14), also known as the State Page of the insurer's Annual Statement. Only CA licensed companies actively doing business in California (with Direct Written Premium greater than $0) are included. Beginning with 2012, we have included a section showing the historical premium and loss information of the CA Proposition 103 lines of business. These are the lines subject to prior approval rate review as specified in Proposition 103 (Prop. 103).

The Top 25 Groups' report shows their breakdown of business written by concentration level, which is defined by the percentages of premium written in 2021 by line of business with respect to that group's total business written. These Top 25 Groups represent 77.96% of California's property and casualty industry.

Here is a comparison of Written Premiums and Loss Ratios of 6 major lines of business:

Line of Business 2020 Written Premium

We have a section for Risk Retention Groups (RRG) that had business in California in 2021. Risk retention groups are created under the federal Risk Retention Act of 1986. The Act permits an RRG to form as an insurance company and requires it follow the insurance laws of at least one state.
