SUBJECT: Updated CNS Intra-day Message Format

As part of the CNS Rewrite, which was implemented on August 6, 2004, NSCC introduced intra-day messages using ISO 15022 format to be used when a participant’s CNS position changes during the day cycle due to a same day settling trade or daytime miscellaneous activity. This format updates the format that was described in NSCC Important Notice number A5668 P&S 5238 Dated August 27,2003.

Attached are the updated message formats that are currently being sent to participants.

A copy of this Important Notice or any other NSCC Important Notice can be found at NSCC’s Web site http://www.nscc.com in the Important Notice section. If you have any questions regarding these modifications, please contact DTCC Relationship Management hotline at (212) 855-4155, or the undersigned at (212) 855-5694.
