(49)To ensure a greater degree of protection of the assets of a CSD from the default of the intermediary, a CSD that accesses another CSD through a CSD link should maintain those assets in a segregated account at the linked CSD. This level of segregation should ensure that the assets of a CSD are segregated from those of other entities and protected appropriately. It is however necessary to allow the establishment of links with third-country CSDs even where individually segregated accounts are not available at the third-country CSD provided that assets of the requesting CSD are in any case adequately protected and competent authorities are informed of the risks resulting from the unavailability of individually segregated accounts and the adequate mitigation of such risks.
