    • One customer account number at Clearstream Banking;
    • One tax rate to be applied to a specific quantity of positions in the targeted ISIN/common code;
  • Customer should specify all the following data in each SWIFT message:
    • Function:
      • New or Cancel. If Cancel, please specify the reference of the SWIFT message to cancel;
    • Country of taxation;
    • Customer account number at Clearstream Banking;
    • Corporate action reference ID (if applicable);
    • Security code: ISIN or common code (the common code is recommended if the security is not deposited in the home market);
    • Corporate action option number (if applicable);
    • Corporate action option code indicator (if applicable);
    • Payment date (optional);
    • Quantity instructed (please refer to the eligible balance on the notification);
    • Tax rate to apply to the quantity instructed;
