Farmers Insurance Group of Companies is composed of a holding company and the various underwriters, reciprocal inter-insurance exchanges, and smaller companies associated with it.
- Farmers Group, Inc. is the holding company and provides insurance management services. It acts under the dba Farmers Underwriters Association. Together with its wholly owned subsidiaries, Truck Underwriters Association and Fire Underwriters Association, they act as the attorneys-in-fact for three reciprocal inter-insurance exchanges — Farmers Insurance Exchange, Truck Insurance Exchange, and Fire Insurance Exchange. However, the Farmers Group, Inc. management company is not an owner of these reciprocal inter-insurance exchanges. The exchanges own several other insurance companies and insurance holding companies, including Mid-Century Insurance Company, Foremost Insurance Company, and Bristol West Insurance Group, as well as Farmers Financial Solutions, LLC, a registered broker-dealer. In this structure, the exchanges hold the insurance risk, while Farmers Group, Inc. earns management fees by running the exchanges' affairs. The only exception is Farmers New World Life Insurance Company, a life insurer owned directly by Farmers Group, Inc.
