Enhancement of ARP services and update to SFTP protocol


The role of information security is increasingly important and has a special status, especially in times of Central Securities Depositories Regulation (CSDR). Therefore, Clearstream Banking AG1, as a CSD, is committed to accept the information regarding the final maturity in the future only via the secure interface of the ARP (Automatic Redemption Processing) application.

The ARP application is a fully automated service for processing all types of redemptions. This service for issuers and their paying agents has been successfully in use for several years and is mainly used for redemptions of certificates, warrants and bonds. The data transfer is sent to CBF using a pre-defined template in CSV format, enabling immediate publication in CBF's processing systems.


1 September 2019

this service will be extended by covering also the handling of partial redemptions in addition to the final maturities.

The templates have been extended for this further development and must be adapted accordingly by customers. The final version of the template will be available soon.

The usage of the ARP service will be mandatory by propagating the data to CBF as per the below listed data delivery channels. A penalty fee will be charged for non-use.

Options for the data delivery

  • Internet
    Data can in the near future be delivered directly to CBF’s Internet File Server within the framework of Secure File Transfer Protocol (SFTP). A valid user / password combination is required. For this please contact Clearstream via the email address new-issues-bonds@clearstream.com.
    The connection via Secure Copy Protocol (SCP) will be no longer supported from 31 October 2019.
  • Via "Connect: Direct"
    Customers who are directly connected to Deutsche Börse's mainframe are able to provide data using the "connect direct" function.

Customer currently sending the ARP file by email to CBF are requested to migrate the data delivery to one of the two before-mentioned delivery channels by the deadline mentioned above. CBF will charge a penalty fee if customers continue to transmit emails after the implementation date.

Important note

From 1 September 2019, issuers and agents will be responsible for providing the relevant redemption information. Data will be processed, if a complete instruction has been received by the deadline. This means either the redemption amount is already fixed by the admission, the redemptions have already been published and processed accordingly (for all issues since December 2014), or the paying agent will have to send an instruction with the required information in the ARP application two business days before maturity date at the latest (until 15:00 CET) as described above.

The delivered information is automatically validated and, if necessary, an error log is sent to the submitter.
