(5)Article 3(2) of Delegated Regulation (EU) 2022/930 requires that the annual supervisory fee for a given DRSP in a given year ( n ) is to be determined based on its applicable turnover. That applicable turnover is to be calculated in accordance with Article 4 of that Delegated Regulation, which requires that, as a rule, the applicable turnover is to be calculated on the basis of the audited accounts of that DRSP for year ( n -2). For CTPs that will start providing services for the first time, there will be no reliable applicable turnover data for the calculation of the annual supervisory fee in the first two years of operation. A special regime based on a fixed annual supervisory fee is therefore required for that period. To prevent the creation of barriers to market entry and to ensure proportionality, while reflecting an estimate of the expenditure necessary to perform the supervisory tasks related to CTPs, that fixed fee should be set at EUR 400 000. In the first year of operation, that fee should be applied on a pro rata basis.
