(4)Where a corporate restructuring event resulting in the change of legal entity identifier (‘LEI’) of a counterparty takes place, the details of the entities identified in a derivative report need to be updated. To ensure the integrity of that information, which is essential for the monitoring of systemic risks to financial stability, it is necessary that the update is performed centrally by the trade repositories. For that reason, a procedure should be established to ensure that trade repositories can update the identifier of the entity in a centralised manner, thus ensuring an efficient, robust and timely process.
