(4)Annual fees are also to be charged to recognised third-country CCPs to cover ESMA’s costs for the performance of its tasks under Regulation (EU) No 648/2012 in relation to such CCPs. For both Tier 1 and Tier 2 CCPs, those tasks include the periodic review of the systemic importance of CCPs pursuant to Article 25(5) of Regulation (EU) No 648/2012, the implementation and maintenance of cooperation arrangements with third-country authorities and the monitoring of regulatory and supervisory developments in third countries. For Tier 2 CCPs, ESMA is also required to supervise on an ongoing basis compliance by those CCPs with the requirements set out in Article 16 and Titles IV and V of Regulation (EU) No 648/2012, including through comparable compliance, where granted. It is therefore appropriate that different annual fees apply to Tier 1 and Tier 2 CCPs.
