MT 503 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 collateral claim consists of three 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), the identification of the collateral action and the contact information.

Sequence B Summary provides information related to the collateral position, ie, the identification of the exposed party, the total exposure amount, the total collateral amount held by the taker, the value of collateral to be added to or to be returned from the collateral held. The sequence contains an optional subsequence with the amounts taken into account to calculate the collateral position. These amounts are required for certain types of exposures. The subsequence also contains the valuation dates and the requested settlement date of the collateral.

Optional sequence C specifies the details of the collateral claimed. It is used by the taker only if the taker wants to receive specific collateral. It is used by the giver to specify the collateral it wants to pull out of the collateral held by the taker. The collateral can be securities, cash, documentary credits or bank guarantees.
