Article 521(2)(a) of Regulation (EU) No 575/2013 (CRR) requires institutions to disclose information regarding their leverage ratio and their management of the risk of excessive leverage in accordance with Article 451(1) of that Regulation starting from 1 January 2015.
The abovementioned requirement applies irrespective of the absence of the implementing technical standard (ITS) mandated in Article 451(2) of the CRR on the uniform disclosure template. Until this ITS is adopted by the Commission, institutions may choose the form in which they disclose the information listed in points (a) to (e) of Article 451(1) of the CRR.
The information to be disclosed in accordance to points (a) to (c) of Article 451(1) of the CRR shall be calculated in accordance with Part Seven of the CRR as modified by Commission Delegated Regulation (EU) 2015/62.
This question goes beyond matters of consistent and effective application of the regulatory framework. A Directorate General of the Commission (Directorate General for Internal Market and Services) has prepared the answer, albeit that only the Court of Justice of the European Union can provide definitive interpretations of EU legislation. This is an unofficial opinion of that Directorate General, which the European Banking Authority publishes on its behalf. The answers are not binding on the European Commission as an institution. You should be aware that the European Commission could adopt a position different from the one expressed in such Q&As, for instance in infringement proceedings or after a detailed examination of a specific case or on the basis of any new legal or factual elements that may have been brought to its attention.
