372. In accordance with the CPMI-IOSCO CDE Guidance the RTS on reporting introduced new package-related fields. This includes field 2.6 'Package identifier', which should, on the one hand, be used by reporting counterparties or entities responsible for reporting as a unique link between reports belonging to the same derivative contract, where the table of fields does not allow to submit the details in only one report and, on the other hand, where the package transaction is composed of a combination of derivative contracts that are negotiated together as the product of a single economic agreement (see also recital 3 and 4 of the RTS on reporting).

373. While there is a requirement for both counterparties to agree on the number of reports to be submitted for a given contract or package transaction and on the UTI's assigned to those reports, there is no need to agree on the identifier between the two counterparties. The 'Package identifier' will be unique for a set of reports belonging together and assigned by each reporting counterparty or entity responsible for reporting on their own. For this reason there is no need to consume a package identifier from trading venues or the other counterparty.

374. Table 21 illustrates the reporting of UTIs and package identifiers in the case of package transactions:
