Commission on Health and Safety and Workers' Compensation
Insurance industry and Coverage
In 1993, workers’ compensation reform legislation repealed California’s 80-year-old minimum rate law and replaced it beginning in 1995 with an open-competition system of rate regulation in which insurers set their own rates based on “pure premium advisory rates” developed by the Workers’ Compensation Insurance Rating Bureau (WCIRB). Subsequent to the repeal of the minimum rate law, the workers’ compensation insurance market became unstable. Major changes were noted: • Insurers seeking to retain or add to their market share engaged in price competition on premium costs. • Many insurance carriers shifted the risk of their workers’ compensation claims to other insurance companies after open rating. This section covers specific issues of coverage, risk, pools and premiums.
