This Form 4 reports securities disposed of pursuant to the terms of the Agreement and Plan of Merger and Combination (the "Merger Agreement"), dated as of July 12, 2021, by and among State Auto Financial Corporation, an Ohio corporation ("STFC"), State Automobile Mutual Insurance Company, an Ohio mutual insurance company ("SAM"), Liberty Mutual Holding Company, Inc., a Massachusetts mutual holding company ("LMHC"), Pymatuning, Inc., an Ohio corporation and wholly-owned indirect subsidiary of LMHC ("Merger Sub I"), and Andover, Inc., an Ohio corporation and wholly-owned direct subsidiary of LMHC, a copy of which was filed as Exhibit 2.1 to STFC's Form 8-K filed with the Securities and Exchange Commission on July 12, 2021.
