(12)As it is the case for the reporting of SFTs, certain identifiers and codes to be used for the reporting of derivative contracts are still being developed. Until such time as those identifiers and codes are available, considered suitable for the purposes of reporting and Implementing Regulation (EU) No 1247/2012 has been amended accordingly, that Regulation provides for the use of an ISO 10692 CFI code to classify derivatives for which an ISO 6166 ISIN code or an AII code are not available, and for the use of a unique trade identifier agreed by the counterparties to identify a derivative report. To ensure legal certainty as regards the appropriate procedure to amend the requirements applicable to the reporting of derivatives contracts, and the required degree of consistency between the reporting of derivatives and of SFTs, Implementing Regulation (EU) No 1247/2012 should only refer to the requirements currently applicable to that reporting.
