TECHNICAL AMENDMENTS TO CDS PROCEDURES

ISSUER CODE WARNING REPORT

NOTICE OF EFFECTIVE DATE

A. DESCRIPTION OF THE RULE AMENDMENT

Background

The proposed amendments were made at the request of the CDS Strategic Development Review Committee ("SDRC") Debt & Equity subcommittee. The issue was raised by a Participant who experienced problems when an Issuer Code used to issue Commercial Paper ran out of available ISIN combinations. The SDRC request was to provide a report to Participants whichprovided a flag when a Participant reached 80% of the available ISIN combinations for a given Issuer Code provided a flag when a Participant reached 80% of the available ISIN combinations for a given Issuer Code. A change will also be made to the existing Eligible Issuer Codes report (RMS156) to provide Issuer Agents with a version of the report which identifies only those of their own issuer codes which are within a 20% threshold of the remaining available ISINs. This new report can be used by Participants to monitor the need to request new money market Issuer Codes.
