The WCIRB governing committee just over a week ago voted to authorize the filing.
The rates are based on the WCIRB’s analysis of the latest available insurer premium, loss, and loss adjustment expense experience reported to the WCIRB and the WCIRB’s actuarial projections.

Since early 2015, the approved advisory pure premium rate level has declined by more than half. In rate filings, the WCIRB has attributed this improvement to several factors, including acceleration in claim settlement, modest claim severity trends and reduced pharmaceutical costs and lien filings.
Much of this improvement is attributable to sweeping workers’ comp reform (Senate Bill No. 863) and subsequent reforms, robust medical fee schedules and efforts to fight fraud in the system, according to the WCIRB.
