(45)In order to carry out its duties effectively, the Authority should have the right to request all necessary information. To avoid the duplication of reporting obligations for financial institutions, that information should normally be provided by the national supervisory authorities which are closest to the financial markets and institutions and should take into account already existing statistics. However, as a last resort, the Authority should be able to address a duly justified and reasoned request for information directly to a financial institution where a national competent authority does not or cannot provide such information in a timely fashion. Member States’ authorities should be obliged to assist the Authority in enforcing such direct requests. In that context, the work on common reporting formats is essential. The measures for the collection of information should be without prejudice to the legal framework of the European Statistical System and the European System of Central Banks in the field of statistics. This Regulation should therefore be without prejudice both to Regulation (EC) No 223/2009 of the European Parliament and of the Council of 11 March 2009 on European statistics 38 and to Council Regulation (EC) No 2533/98 of 23 November 1998 concerning the collection of statistical information by the European Central Bank 39 .
