(2)The global legal entity identifier (‘LEI’) system has now been fully implemented and each counterparty to an SFT should therefore only use that system to identify a legal entity in a report. For the counterparty's use of the LEI system to be effective, that counterparty should ensure that the reference data related to its LEI are renewed in accordance with the terms of an accredited LEI issuer (Local Operating Unit). An extension of the global LEI system to identify branches of legal entities is currently being developed. Until such time as that extension is finalised and considered suitable for the purposes of reporting SFTs, and this Regulation is amended accordingly, the ISO code of the country where the branch is located should be used to identify that branch where an SFT is concluded through a branch office of a counterparty.
