MT 305 Format Specifications

The MT 305 consists of two sequences:

• Sequence A General Information contains general information about the option as well as about the confirmation itself.

• Sequence B Reporting Information provides transaction information that must be reported to a trade repository. This sequence is optional and is only to be used for reporting to trade repositories, although some fields, for example, unique transaction identifier and prior unique transaction identifier, might be used on regular confirmations.
