Processing defective and replacement certificates Non-collective Safe Custody (NCSC) The settlement of transactions in NCSC securities takes place through the ICSD’s Creation platform. In addition to the accounts held by customers of Clearstream Banking Luxembourg (CBL) under Luxembourg law, CBF has its own series of accounts, which are technically and legally independent (referred to as six-series accounts) and are governed by German law. These six-series accounts are kept via Creation parallel to and in connection with the CBF customers' CASCADE accounts. In order to settle trades in NCSC securities executed on German stock exchanges, the delivery instructions are generated and transmitted directly to the Creation platform. For the settlement of OTC transactions in NCSC securities, customers submit their instructions directly to Clearstream Banking Luxembourg via their preferred connectivity channel. Customers may obtain reports on six-series accounts either through direct interfaces to CBL, as the operator of the Creation platform, or through the communication channels of CBF. Detailed information on the settlement processes for the ICSD can be found in the CBL Customer Handbook. |
