The National Association of Insurance Commissioners has issued its annual Market Share Data Reports for both the Property & Casualty Insurance Marketplace, as well as for the Life & Fraternal Insurance Marketplace. As in the past, the data offered here reflects a compiled list of market share data based upon filings of countrywide premium submitted to the NAIC from Property & Casualty insurers as reported on the State Page of the NAIC’s annual statement for insurers.
The data is then compiled and included in various reports on cumulative market share data for the seven major lines of insurance in the United States: All lines; Private Passenger Personal Auto; Commercial Auto; Workers’ Compensation; Medical Professional Liability; Homeowners’ Multi-Peril; and Other Liability (excluding auto liability).
