Ohio Insurer Pulls Out: Citing “10 years of underwriting unprofitability,” Ohio Casualty Corp. said it will withdraw from the California market, where it has done business since the early 1940s. The Hamilton, Ohio-based company had $225 million of premiums in force in California at year-end 1991--less than 1% of the state’s insurance market. Marketing Director Don Dehny said the company’s inability to make money in California “has become more acute with the continuing regulatory problems that have evolved out of Proposition 103”--the 1988 voter initiative that mandated premium rollbacks and regulatory changes. Ohio Casualty needs regulators’ permission to withdraw and has notified the Department of Insurance of its plans.
