Audit and Enforcement Unit - Annual report of inventory

The California Code of Regulations, title 8, section 10104 requires claims administrators to file, by April 1 of each year, an annual report of inventory (ARI) with the DWC administrative director (AD) indicating the number of claims reported at each adjusting location for the preceding calendar year. Even if there were no claims reported in the prior year, the report must be completed and submitted to the DWC Audit Unit. Each adjusting location is required to submit an ARI, whether or not it receives a form for reporting claims from the Audit Unit, unless its ARI requirement has been waived by the AD.

If a claims administrator’s ARI requirement has been waived by the AD for compliance with the data reporting requirements of the Workers’ Compensation Information System, it must file an annual report of adjusting locations. This report is to be filed annually on April 1 of each calendar year for the adjusting location operations as of Dec. 31 of the prior year. A new form has been provided below, which can be used for this purpose.

Claims administrators are required to report any change in the information reported in the ARI or annual report of adjusting location within 45 days of the effective date of the change. 

Questions about submission of the ARI or the annual report of adjusting locations may be directed to the Audit Unit:
