WCIRB Submits July 1, 2017 Filing

Today, the WCIRB submitted a July 1, 2017 Pure Premium Rate Filing to the California Department of Insurance (CDI) proposing advisory pure premium rates that average $2.02 per $100 of payroll effective July 1, 2017. The average proposed advisory pure premium rate is 16.5% lower than the corresponding industry average filed pure premium rate of $2.42 as of January 1, 2017 and 7.8% less than the Insurance Commissioner's approved average January 1, 2017 advisory pure premium rate of $2.19. 

In the Executive Summary of the Filing, the WCIRB highlights the keys drivers of the WCIRB’s fifth consecutive proposed advisory pure premium rate decrease since 2015 including downward medical loss development in part driven by continued acceleration in claim settlement, decreasing indemnity claim frequency and lower than projected loss adjustment expenses. The WCIRB also notes that while these loss and loss adjustment expense trends are reducing the indicated pure premium rate, high levels of lien filings, continued growth in cumulative injury claims and rising  medical severities could erode the impacts of these trends and warrant continued monitoring.

The Filing and related documents are available in the Publications and Filings section of the WCIRB website ( The CDI will schedule a public hearing to consider the Filing. Once the Notice of Proposed Action and Notice of Public Hearing is issued, the WCIRB will post a copy on its website and issue a Wire Story.
