Rather than buy workers' compensation coverage on the open market, some employers prefer to become self-insured and pay their own claims. That group is the niche that Safety National Casualty aims to serve best. The company provides a variety of alternative workers' compensation products, primarily excess workers' compensation insurance. It also offers insurance bonds for self-insured companies, high-deductible workers' compensation insurance, commercial auto and liability coverage, and programs that integrate workers' compensation and disability benefits. Founded in 1942, Safety National Casualty is a subsidiary of financial services firm Delphi Financial Group, which is in turn owned by Tokio Marine Holdings.
