WCIRB Updates Loss Elimination Ratios and Advisory Plan Tables

The Workers’ Compensation Insurance Rating Bureau of California (WCIRB) has published the 2021 update to the loss elimination ratios that were used in computation of classification relativities in the recently approved January 1, 2021 Regulatory Filing. This annual update reflects the most current claim severity and benefit on-leveling factors. Additionally, the WCIRB has updated other rating values included in the advisory California Retrospective Rating Plan, California Large Risk Deductible Plan and California Small Deductible Plan based on this more current information.*

* Advisory plans are developed by the WCIRB for the convenience of its members. These Plans were submitted to the Insurance Commissioner for informational purposes, but do not bear the official approval of the California Department of Insurance and are not a regulation. An insurer must make an independent assessment regarding its use of these Plans based upon its particular facts and circumstances.
