The Continuous Net Settlement (CNS) System is an automated book-entry accounting system that centralizes the settlement of compared security transactions and maintains an orderly flow of security and money balances.
Throughout the CNS processing cycles, the system generates reports that provide participants with a complete record of security and money movements and related information (see key reports).
CNS provides clearance for equities, corporate bonds, Unit Investment Trusts and municipal bonds that are eligible at The Depository Trust Company (DTC).
All NSCC settling members are eligible to use the service.
CNS offers users the following efficiencies and risk protections:
On T+3, all transactions are netted by issue to net long (buy) and net short (sell) positions, and then are further netted with positions that remained open after T+3; this includes positions due to settle that day as well as fail positions. Members' receive and deliver obligations are to and from NSCC.
The CNS automatic delivery process occurs in two cycles: the "night cycle" during the early morning (approximately 1:30 a.m.) of settlement date and the continuous "day cycle" later that day.
CNS short positions, which represent securities owed by participants to NSCC, are compared against their DTC accounts to determine issue availability. If shares are available, they are transferred from the member's account at DTC to NSCC's account at DTC to cover participants' short obligations to CNS. To control the automatic delivery of securities from their DTC accounts, participants can use CNS exemption procedures (partial settlements are permissible).
CNS long positions, which represent securities owed by NSCC to participants, are processed in an order determined by an algorithm built into the system. Securities are automatically allocated to users' long positions as the securities are received by NSCC. Participants can request that they receive priority for some or all issues on a standing or override basis. Submission of buy-in notices also will affect the priority of a member's long position.
Daily money settlement is based on the value of all settled trades plus or minus mark-to-the-market figures for all open CNS positions.
Through the CNS System, NSCC offers three ancillary services:
