CML has responded to the Prudential Regulation Authority  (PRA) consultation on implementing CRD 4. CML welcomes PRA's proposal to exercise discretions under the CRR to apply a 35% risk weight to "buy-to-let" mortgages and to replace the 90 days past due definition of material default with 180 days past due for exposures secured on residential real estate. CML also asks for the possibility of including structures involving a number of individual securitisations, such as under the Help-to-Buy scheme, within the significant risk transfer process.
