(57)To support market monitoring by the supervisory authorities, information gathering and sharing through supervisory reporting should be improved by subjecting UCITS to supervisory reporting obligations. Duplicative reporting requirements that exist under Union and national law, in particular Regulations (EU) No 600/2014 and (EU) 2019/834 and Regulations (EU) No 1011/2012 and (EU) No 1073/2013, could be eliminated to improve efficiency and reduce administrative burdens for management companies. The ESAs and the ECB, with the support of competent authorities, where necessary, should assess the data needs of the different supervisory authorities, so as to ensure that the information to be reported under the supervisory reporting template for UCITS is sufficient.
