In a Mass Transfer scenario, an “Active Account” is reportable to CAIS once there is Transaction-reportable activity for the FDID under the acquiring Industry Member’s CRD number. The Mass Transfer must be reported in accordance with the guidance in the Full CAIS Technical Specifications for Industry Members, including all applicable fields (e.g., priorCATReporterCRD and priorCATReporterFDID). The FDID must be reported to CAIS by 8 am ET on T+1 where T represents the CAT Trading Day of the Transaction-reportable activity. 

For example, if an FDID was acquired on calendar date October 1, but did not have any Transaction-reportable activity until CAT Trading Day November 15, the FDID is required to be reported to CAIS by 8 am ET on November 16 (assuming November 16 is a CAT Trading Day).
