The ratings of State Automobile Mutual Insurance Company (Columbus, OH) and its insurance subsidiaries are unchanged . State Auto Insurance Companies are publicly-traded through their intermediate holding company, State Auto Financial Corporation (STFC) (NASDAQ: STFC).

These transactions, which were effective December 31, 2012, are part of STFC management’s ongoing initiatives to streamline its operations.
