(6)The tasks performed by ESMA under Regulation (EU) No 648/2012 in relation to recognised Tier 1 CCPs will largely be the same for each Tier 1 CCP independently of their size. It is therefore appropriate that the costs incurred by ESMA in relation to recognised Tier 1 CCPs are covered by levying an annual fee of the same amount on each recognised Tier 1 CCP. In relation to recognised Tier 2 CCPs, in order to ensure a fair allocation of fees which, at the same time, reflects the actual administrative effort required by ESMA for the performance of its tasks with respect to each Tier 2 CCP, annual fees should also take account of the turnover of the Tier 2 CCP.
