MT566 Scope

This message is sent by an account servicer (account servicing institution) to an account owner or its designated agent. The account servicer may be a local agent (sub-custodian) acting on behalf of their global custodian customer, or a custodian acting on behalf of an investment management institution or a broker/dealer.

This message is used to confirm to the account owner that securities and/or cash have been credited/debited to an account as the result of a corporate action event.

This message may also be used to:

  • reverse a previously sent corporate action confirmation

  • re-send a corporate action confirmation previously sent

  • provide a third party with a copy of the message.

MT566 Usage Rules

  • Unless an MT 564 Corporate Action Notification was not previously sent or unless pursuant to a bilateral agreement, general details of corporate action event should not be reiterated in the MT 566. If details are included, the same event details should not be repeated in both the sequence Corporate Action Details and the sequence Corporate Actions Confirmation. The sequence Corporate Actions Details should convey details that are common to the corporate action event while details appearing in the sequence Corporate Action Confirmation should be specific only to the specific posting.

  • The quantity of securities reported in the sequence Underlying Securities represents the balance before the posting was effected.

  • The sequence Financial Instrument Attribute (FIA) is intended to provide additional information regarding the terms and conditions of a securities issue. The objective of the sequence FIA is to ensure unambiguous identification of the security by the Receiver. It is recommended that the sequence FIA not be used unless required by a specific corporate action event, pursuant to a bilateral agreement, or when a valid ISIN or security identifier is not available.

  • In case of blocking of shares, depending on your internal processing method, you can use either an MT 566 Corporate Action Confirmation or an MT 508 Intra-Position Advice. The MT 566 is to be used when the securities safekeeping account is debited and another securities safekeeping account is credited. The MT 508 is to be used when the securities remain in the same securities safekeeping account but are given a blocked status.
