(5)Agency and model risks are more prevalent for securitisations than for other financial assets and give rise to some degree of uncertainty in the calculation of capital requirements for securitisations even after all appropriate risk drivers have been taken into account. In order to capture those risks adequately, Regulation (EU) No 575/2013 should be amended to provide for a minimum 15 % risk-weight floor for all securitisation positions. Resecuritisations, however, exhibit greater complexity and riskiness and, accordingly, only certain forms of resecuritisations are permitted under Regulation (EU) 2017/2402. In addition, positions in resecuritisations should be subject to a more conservative regulatory capital calculation and a 100 % risk-weight floor.
