(12)National competent authorities incur costs when carrying out work pursuant to Regulation (EU) 2015/2365 and as a result of any delegation of tasks by ESMA to national competent authorities pursuant to Article 74 of Regulation (EU) No 648/2010 and in accordance with Article 9(1) of Regulation (EU) 2015/2365. The fees charged by ESMA to trade repositories should also cover those costs. In order to avoid competent authorities incurring a loss or profit from carrying out delegated tasks or from assisting ESMA, ESMA should reimburse the actual costs incurred by that national competent authority.
