(53)The resolution of a CCP should not entail calling on extraordinary public financial support. The outstanding recovery tools and resolution tools, in particular the write-down tool, should be applied to the fullest extent possible before or together with any public sector injection of capital or equivalent extraordinary public financial support is given to a CCP. The use of extraordinary public financial support to assist in the resolution of failing institutions is to be a last resort, be limited in time and comply with the relevant State aid provisions.
