About The Ohio Casualty Insurance Company

Ohio Casualty underwrites a variety of commercial property/casualty insurance products in the Midwest and other regions of the US. The company's offerings include property and general liability, equipment breakdown, workers' compensation, schools, and commercial farm policies. The company also offers loss prevention programs to its customers. Ohio Casualty's products are sold in seven mid-central and eastern states and Washington, DC. Historically, half of its customers are contractors or artisans, the rest are typically smaller business owners, including merchants and service providers. The company is owned by Liberty Mutual.

Geographic Reach

Ohio Casualty operates in Delaware, Kentucky, Maryland, Ohio, Pennsylvania, Virginia, West Virginia, and Washington, DC.


In addition to underwriting and claims management services, the organization provides loss prevention consulting and online bill payment tools. Ohio Casualty is part of the Liberty Mutual Agency division, which offers a range of personal and commercial property/casualty insurance products.

Sales and Marketing

The company's policies are marketed through independent agents. Ohio Casualty's customers include contractors, hotel and condominium owners, schools, wholesalers, religious organizations, food processors, garages, manufacturers, restaurants, offices, and retail stores.


Ohio Casualty is working to extend its offerings for commercial customers, with a focus on small businesses. In 2011 the company added 60 new business classes to its Commercial Protector offering, which provides broad property and liability coverage for smaller business entities. In addition, the firm has focused on upgrading technology tools in recent years to increase ease of use for clients and agents.

Company Background

Liberty Mutual acquired Ohio Casualty in 2007 and added it to its stable of regional property/casualty and specialty insurance companies. Following the transaction, Ohio Casualty became part of Liberty Mutual's commercial segment (under the Agency Markets business); its personal insurance business and specialty commercial insurance business were transferred to other Liberty Mutual companies.
