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In 1993, workers' compensation reform legislation repealed California's 80-year-old minimum rate law and replaced it beginning in 1995 with an open-competition system of rate regulation in which insurers set their own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). The Commission has examined issues involving the insurance market, security for payment of compensation benefits, and the requirement that all employers secure the payment of compensation benefits.
