Life/Fraternal, Property/Casualty Reports Now Available Online

WASHINGTON, D.C. (March 1, 2012) — The National Association of Insurance Commissioners (NAIC) today released two sets of data that help provide an indicator of the degree of market concentration in lines of business and identify leading insurance writers.

The 2011 market share data for life/fraternal and property/casualty insurers include countrywide direct written premium for the top 25 groups and companies as reported on the State Page of the annual statement for insurers that report to the NAIC.

The property/casualty report contains cumulative market share data for the following lines of business: personal auto, commercial auto, workers' compensation, medical professional liability, homeowners and other liability (excluding auto liability) insurance.

The life/fraternal market share report contains cumulative market share data for the following lines of business: life, annuity considerations, and aggregate total of life insurance, annuity considerations, deposit-type contract funds, other considerations and accident/health insurance.

Both reports will be refreshed daily through March 9 and then each Monday through the end of March. These abbreviated reports are available for viewing at no charge on the NAIC website:

For questions regarding the reports or data, contact the NAIC Research & Actuarial Department.

Complete and in-depth market share information will be featured in the 2011 Market Share Reports for Property/Casualty and the 2011 Market Share Reports for Life/Fraternal, which will be available this summer.
