Five-Year Extension of CAT Timestamp Exemption
If your firm reports trade data to the Consolidated Audit Trail (CAT) and your systems capture timestamps finer than a nanosecond, you must truncate those timestamps to the nanosecond level for CAT submission through April 8, 2030. The NYSE amended its Compliance Rule to reflect this extension and the change became operative upon filing (filed August 27, 2025).
