(20)While Regulation (EU) No 909/2014 requires national supervisors to cooperate with and involve relevant authorities, national supervisors are not required to inform those relevant authorities whether or how their views have been considered in the outcome of the authorisation process or whether additional issues have been identified in the course of regular reviews and evaluations. The relevant authorities should therefore be able to issue reasoned opinions on the authorisation of CSDs and the review and evaluation process. The competent authorities should take into account such opinions or explain why such opinions were not followed. The competent authorities should inform the relevant authorities, as well as other authorities consulted, of the results of the authorisation process. The competent authorities should inform the relevant authorities, ESMA and the college of the results of the review and evaluation process.
