(37)The requirements for using the designation ‘simple, transparent and standardised’ (STS) securitisation are new and will be further specified by EBA guidelines and supervisory practice over time. In order to avoid discouraging market participants from using that designation, competent authorities should have the ability to grant the originator, sponsor and SSPE a grace period of three months to rectify any erroneous use of the designation that they have used in good faith. Good faith should be presumed where the originator, sponsor and SSPE could not know that a securitisation did not meet all the STS criteria to be designated as STS. During that grace period, the securitisation in question should continue to be considered STS-compliant and should not be deleted from the list drawn up by ESMA in accordance with this Regulation.
