A look at the largest Workers’ Compensations Insurers in the nation
As it does every March, the National Association of Insurance Commissioners has released its annual market share report of the top 25 P&C insurers nationwide. The list is based on filings to the N.A.I.C. and represents the top 25 groups and companies based upon data reported on the State Page of the NAIC’s annual statement for insurers.
Last week, we took what we thought was a final look at market shares in the U.S. v. Massachusetts. In reviewing the major markets, and with the publication of the Massachusetts Workers’ Compensation Advisory Council’s Annual Report, Agency Checklists thought it would be remiss if it did not include a comparison of the major workers’ compensation companies in the U.S. vis-a-vis the top insurers in Massachusetts.
