What is expected to be in CAIS LTID on April 26, 2021, when mandatory reporting starts?
Beginning April 26, 2021, Large Industry Members will be required to report into CAIS LTID all FDIDs with associated LTIDs or ULTIDs with Reportable Activity on or after April 26, 2021. Firms may choose to report accounts without associated LTIDs or ULTIDs, but there is no requirement to do so until the implementation of Full CAIS. See CAT Alerts 2022-01 and 2023-01 for the Full CAIS Implementation Schedule.
