The Workers’ Compensation Insurance Rating Bureau of California (WCIRB) is the designated statistical agent of the California Insurance Commissioner. For over 100 years, the WCIRB has been California’s trusted, objective provider of actuarially-based information and research, advisory pure premium rates, and educational service integral to a healthy workers’ compensation system.
Every insurance company authorized to transact workers’ compensation insurance in the state of California must be a member of the WCIRB.
The WCIRB collects premium and loss data on every workers’ compensation policy written in California. The data provides the basis for developing proposed advisory pure premium rates, determining experience modifications, publishing reports on trends in the California workers’ compensation industry and providing useful analytical tools and information to various workers’ compensation insurance constituents.
The WCIRB has three standing committees – the Governing Committee, the Classification and Rating Committee and the Actuarial Committee. These committees meet throughout the year; their meeting agendas, minutes and other related materials can be found on the Committee Documents page under Filings and Plans.
When necessary, the WCIRB convenes informal working groups to provide feedback and needed expertise to WCIRB staff to assist in formulating specific proposals that will be presented to the Classification and Rating Committee, Actuarial Committee and/or Governing Committee.
