(12)Article 153(6) of Regulation (EU) No 575/2013 enables institutions to apply to their purchased corporate receivables the risk quantification standards for retail exposures where it would be unduly burdensome for those institutions to use the risk quantification standards for corporate exposures, provided the conditions set out in Article 154(5) of that Regulation are complied with. That same treatment should also be available for qualifying securitised exposures and, for those purposes, eligibility criteria that are appropriate for those exposures should be expressly laid down.
