MT500 Scope

This message is sent by an account owner to an account servicer (account servicing institution). The account owner may be a global custodian which has an account with its local agent (sub custodian), a local agent (sub custodian) which has an account with its clearing agent, or a registration provider or a financial institution which has an account with its local agent (sub custodian).

This message is used to:

instruct the registration, deregistration or reregistration of a financial instrument at the registration provider,
request the cancellation of a registration instruction previously sent by the account owner (the function of the message is CANC).

The registration instruction may be linked to other settlement instructions, for example, in case the settlement does not take place before the registration process is finished, using the linkages sequence.

MT500 Network Validated Rules

C1 If the message is a cancellation, that is, Function of the Message (field 23G) is CANC, then subsequence A1 (Linkages) must be present at least once in the message, and in one and only one occurrence of A1, field :20C::PREV must be present; consequently, in all other occurrences of A1, field :20C::PREV is not allowed.

Sequence A if field :23G: is ...	Then subsequence A1 is ...	And field :20C::PREV is ...
CANC	Mandatory (minimum one occurrence of A1 must be present)	Mandatory in one occurrence of subsequence A1, and not allowed in all other occurrences of subsequence A1
NEWM	Optional	Not applicable

Sequence A

if field :23G: is ...

Then subsequence A1 is ...

And field :20C::PREV is ...

CANC

Mandatory (minimum one occurrence of A1 must be present)

Mandatory in one occurrence of subsequence A1, and not allowed in all other occurrences of subsequence A1

NEWM

Optional

Not applicable

MT500 Usage Rules

When the message is used as a cancellation, the linkage sequence must contain the reference of the original instruction.
The Identification of Financial Instrument in sequence B Registration Instruction Details identifies the financial instrument to be registered. The Identification of Financial Instrument in sequence D Corporate Action Details identifies subscription rights or exercise warrants from a corporate action.
