In response to events relating to the close-out of Lehman Brothers in 2008, NSCC and DTC have been engaged with the industry in a series of initiatives designed to improve the efficiency and reduce risks associated with transactions processed through NSCC’s Automated Customer Accounts Transfer service (“ACATS”). Previous initiatives focused on CNS-eligible and mutual fund ACATS obligations.

As a next step in this series of initiatives, a new ACATS settlement process has been developed for enhanced efficiency and risk reduction for ACATS transfers of CNS-eligible securities and assets that are eligible for settlement at DTC, but not in CNS (“non-CNS DTC-eligible assets”).

The changes address processing and risk-related concerns with respect to ACATS processing of CNS-eligible securities and non-CNS DTC-eligible assets:

• First, this initiative creates functionality for NSCC to track non-CNS DTC-eligible ACATS obligations on ACATS settlement date and reverse only those uncompleted transactions of the defaulting Member in the event of a default. Previous initiatives focused on reversals of CNS-eligible and mutual fund ACATS obligations.
• Second, the proposed modifications allow NSCC to track CNS ACATS transactions in case of multiple Member defaults on ACATS settlement date.
• Third, revised processing ensures that non-CNS DTC-eligible items are credited to a no lien location, in the same way that CNS eligible items are.

The project completed migration to production in June 2014.
