(2)Without prejudice to the ultimate responsibility of the CCP’s competent authority and to further enhance supervisory convergence and the consistent functioning of all CCP colleges, the European Securities and Markets Authority (ESMA) should coordinate the functioning of the colleges and should ensure that each college performs its tasks and achieves its objectives in accordance with Regulation (EU) No 648/2012. To that aim, and with the objective of converging supervisory best practices, the co-chairs of the CCP college should discuss the implementation of the annual supervisory priorities referred to in Article 24a(7), point (ba), of Regulation (EU) No 648/2012.
