About State Auto Insurance Companies

State Automobile Mutual Insurance, informally known as State Auto Group, hosts a non-stop pool party. Through a constellation of subsidiaries, the company provides both personal and commercial property/casualty insurance in the US. It owns 61.9% of publicly traded State Auto Financial, which, in turn, holds a fistful of insurance subsidiaries. Collectively, the companies sell their products through approximately 2,600 independent agencies throughout the US. All are part of a pooling arrangement in which State Auto Group assumes the premiums, losses, and expenses from each and returns a portion to participants based on prearranged percentages. State Auto Group keeps the balance of the pooled business.


State Auto Group's Rockhill Holding unit writes specialty excess and surplus insurance for the small and midsized commercial markets in most US states. (However, in 2017 the Group announced plans to exit the excess and surplus business altogether.) Rockhill also provides workers' compensation products.

The group's other subsidiaries include SA Wisconsin, Meridian Security, and Patrons Mutual, each of which provides property/casualty coverage.

Geographic Reach

State Auto Group's operating subsidiaries provide insurance coverage in all US states and the District of Columbia.

Sales and Marketing

State Auto Group sells its products through a network of independent retail agents; specialty insurance is distributed through wholesale brokers and managing general underwriters.


After struggling with underwriting losses in 2014, State Auto Group has made moves to improve its bottom line. It adjusted its personal lines product pricing and introduced discounts for customers investing in smart home technologies. The group also exited certain businesses such as commercial transportation and its specialty program unit, and in 2017 announced plans to shut down its excess and surplus operations. Other efforts have included adding additional agencies and upgrading its technology platforms. With these changes, the group has seen new business grow and it has reduced its net losses substantially (although Hurricanes Harvey and Irma didn't help.)
