(5)If, after registration, a trade repository starts offering ancillary services and thereby falls into a higher category in terms of expected total turnover, the trade repository should pay the difference between the initial registration fee and the registration fee corresponding to the category of higher expected turnover. Conversely, where a trade repository stops offering ancillary services after registration, it should not be reimbursed by ESMA as the expenditure necessary to assess the application of a high turnover trade repository has effectively been spent during registration.
