Information for New WCIRB Members

WCIRB Overview

The Workers’ Compensation Insurance Rating Bureau of California (WCIRB) is the designated statistical agent of the California Insurance Commissioner. For over one hundred years, the WCIRB has been California’s objective, trusted and integral provider of actuarially-based information and research, advisory pure premium rates, and educational service integral to a healthy workers’ compensation system. This statement is echoed in the open letter from our CEO and President, Bill Mudge, to the California workers’ compensation community, outlining our commitment to all stakeholders.

Every insurance company authorized to transact workers’ compensation insurance in the state of California must be a member of the WCIRB.

WCIRB Primary Functions

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.

WCIRB Governance

The WCIRB has three standing committees - the Governing, Classification and Rating, and the Actuarial Committee. These committees meet throughout the year; their meeting agendas, minutes and other related materials can be located on the Committee Documents page.

When necessary, the WCIRB convenes working groups to provide information, feedback and needed expertise to the WCIRB to assist in formulating specific proposals that will be presented to the Classification and Rating Committee, Actuarial Committee and/or Governing Committee.
