MT566 — Corporate Action Confirmation
The "it happened" notice. The custodian tells the holder that the dividend has been credited, the split applied, the rights exercised — with the exact amounts posted, complementing the MT564 announcement.
Purpose
MT566 confirms to the securities holder the actual execution of a corporate action previously announced by MT564. It carries: the event reference, the cash amount actually credited (or debited), the securities actually allocated (for a split, stock dividend, exercised rights), the actual effective date on the account (POST = posting date), and the beneficiary cash account.
Issued typically on payment day, after the custodian has received the funds from the central depositary and posted them to holders' accounts. It is the holder's accounting reference and the basis for reconciling expected entitlement (ENTL in MT564) versus actual proceeds (PSTA in MT566).

- CACONF — Corporate Action Confirmation: exercised option (CAON), option type, actual payment date.
- CASHMOVE and SECMOVE — actual cash and securities movements posted.

1 June 2026, position unchanged at 200 shares (a cash dividend does not change unit
count):

Common pitfalls
- PSTA ≠ ENTL — the posted amount (
:19B::PSTA//) can differ from the announced entitlement due to withholding tax. Document the delta with:92A::WITL//. - CORP reference not preserved — the event reference
:20C::CORP//must be verbatim from MT564. Changing it breaks the link and the notification-confirmation reconciliation. - Confirmation without prior announcement — an MT566 with no prior MT564 is anomalous and must be handled as an exception.
- CONB vs ELIG — the post-event confirmed balance can differ from the initial eligible balance (split, bonus issue). For a cash dividend however, CONB = ELIG.
- Posting date in the past —
:98A::POST//must reflect the actual posting date. If it is in the past relative to PAYD, document the reason in narrative (post-event correction).
