More generally, any T2S eligible securities issued by ESES and LuxCSD, including those currently held via CBL², can be transferred to CBF and would be part of the OneClearstream service with exception of securities that:

• are subject to ongoing corporate action events(these securities will be made eligible within 20 T2S business days); or

The preliminary lists with all impacted ISINs will be published one month before the migration and then, two weeks before the migration. The final list of ISINs will be published on Thursday prior to each migration date.

The list will be in Excel format and provide the following information:

We remind our customers that all OneClearstream asset servicing bookings in T2S-eligible proceeds and its related reporting will be done at the customer's sub-account level.

Ahead of the OneClearstream activation, customers are requested to make sure that each sub-account has an appropriate account setup and is well subscribed to the relevant reporting.

To ensure a smooth OneClearstream activation on 9 April 2018 (and if not done yet with the OneClearstream activation for Italy on 26 March 2018):

• The customer's sub-accounts without the appropriate reporting subscription will be subject to a default reporting setup by Clearstream Banking as described in the OneClearstream Migration Guide.
• The customer's sub-accounts without the appropriate T2S setup will be linked by default by Clearstream Banking to the DCA of their main account. This default linkage is a technical setup and only applies to debits and credits originated by OneClearstream. The current DVP participation flag setup remains unchanged.

Non-migrating ISINs   

The list of non-migrating ISINs currently held in CBL and not in the scope of the migration will be available on the Clearstream website in addition to the list of impacted ISINs.

Note: After migration, to accept in CBF any new ESES and LuxCSD issued securities supported by OneClearstream, customers should contact their dedicated Client Services officer.
