The WCIRB does not anticipate any changes to the content or requirement for submission of the annual Aggregate Indemnity and Medical Costs Call immediately. The WCIRB may consider modifications to the annual Aggregate Indemnity and Medical Costs Call content once the volume of indemnity transaction data collected via the Indemnity Data Call grows. It is unlikely that the Aggregate Indemnity and Medical Costs Call requirement will be eliminated completely.
