MT 505 Format Specifications

The user header of the message (block 3) is mandatory and must contain a code in the Validation Flag field 119 ( {3:{119:xxxx}} ) to identify the exposure type or collateral reason.

These codes may be used for routing purposes.

The substitution consists of four sequences.

Sequence A General Information provides general information about the message and the collateral transaction, ie, the function of the message, the identification of the collateral transaction, the references of the linked messages, the identification of the underlying agreement(s), the identification of the parties, the reason for which collateral is needed, the exposure type and the contact information.

Sequence B specifies the details of both the collateral to be substituted and the new collateral. The collateral can be securities, cash or other collateral. The other collateral indicates trade instruments, ie, documentary credits and bank guarantees. This sequence may also contain the settlement details for a piece of security or cash collateral. If the settlement details for all pieces of securities collateral are the same, these details are not present in this sequence, but included once in sequence C. If the settlement details for all pieces of cash collateral are the same, these details are not present in this sequence, but included once in sequence D.

Sequence C contains the common securities settlement details, ie the settlement details of the proposed securities when they are not included in sequence B at the level of the individual piece of collateral.

Sequence D contains the common cash settlement details, ie the settlement details of the proposed cash when they are not included in sequence B at the level of the individual piece of collateral.
