Notice of Effective Date – Technical Amendments to CDS Procedures – WR 1346 – New York Link collateral requirement alert – CDS Clearing and Depository Services Inc.

A. DESCRIPTION OF THE CDS PROCEDURE AMENDMENTS

Background

WR1346 -- New York Link collateral requirement alert

Effective May 1, 2010, CDS's New York Link participants have an obligation to provide CDS with collateral for the NSCC Participant Fund for New York Link Pool to cover their NSCC settlements by 9:00 a.m. ET.

CDS currently provides these participants with a daily Collateral Valuation Summary Report at 7:00 a.m. ET that details their collateral deficiency or excess, as reported to CDS by NSCC. As a courtesy to western clients that may have challenges meeting the deadline, CDS will now provide an alert with the same information contained in the report that may be sent to a subscriber's email prior to regular business hours, allowing them to instigate corrective measures earlier. Although CDS's service level agreement for delivery of the email will be the same as for the report (7:00 a.m. ET), in practice the email creation process will be triggered by the receipt and processing of the NSCC collateral information, and will generally be performed at 5:30 a.m. ET.

Participants will subscribe to the email alert and/or a web based alert through the existing Electronic Alert System (EAS). These alerts will provide New York Link participants with their NSCC current collateral requirement, the amount of collateral already provided and the difference in amounts (i.e. excess or shortage).

In addition to the alert for New York Link participants, the previously implemented "Warrant Subscriptions" alert for Depositary Agents has been removed in text form and embedded in the table.

The new "Projected Payment Rejection" and "Unreleased and Pending Entitlement Payments" alerts for Transfer Agents, documented in a separate Technical Notice "Payment Matching for Transfer Agents", dated 30 April 2010 and being implemented at the same time as the New York Link collateral requirement alert, is also included in this new table.
