The activation of OneClearstream services for CBF Investor CSD links is subject to a pre-defined mandatory rollout timeline per market.
  • the  OneClearstream Asset servicing - CBF issued securities  document that describes the OneClearstream asset servicing processes for CBF as the Issuer-CSD. The activation of OneClearstream services for CBF issued securities is optional.

Customers with CBL accounts or CBF 6-series accounts are informed about the changes to the existing services via Release information and dedicated announcements.
