WCIRB First Quarter 2019 Experience Report Released

The Workers’ Compensation Insurance Rating Bureau of California (WCIRB) has released its quarterly update on California statewide insurer experience valued as of March 31, 2019.


Highlights of the report include:


  • California written premium for the first calendar quarter of 2019 is 12 percent below the same period for 2018, suggesting premium decreases will escalate in 2019.
  • The average charged rate for the first three months of 2019 is 10 percent below that for 2018 and 31 percent below the peak in 2014.
  • The WCIRB projects the ultimate accident year loss ratio for 2018 to be four points above that for accident year 2017, driven by higher claim severities for 2018 and lower premium rates.
  • The 91 percent combined loss and expense ratio projected for accident year 2018 represents the sixth consecutive year of combined ratios below 100 percent.
  • The ratio for the percent of open indemnity claims closed in the next year increased in each of the last six years and in 2018 is the highest ratio since 1999.
  • Cumulative trauma (CT) claim rates continue to increase in accident year 2017, and the ratio of CT claims to all indemnity claims has increased by more than 80 percent since accident year 2005.
  • The projected total loss and allocated loss adjustment expense claim severity for accident year 2018 is 6 percent higher than that for accident year 2017, following several years of flat to modestly declining claim severities.
