(7)The supplementary supervision of large, complex, internationally operating financial conglomerates requires coordination throughout the Union, in order to contribute to the stability of the internal market for financial services. To that end, competent authorities need to agree upon the supervisory approaches to be applied to those financial conglomerates. The ESAs should issue, in accordance with Article 56 of Regulation (EU) No 1093/2010, of Regulation (EU) No 1094/2010 and of Regulation (EU) No 1095/2010, through the Joint Committee, common guidelines for those common supervisory approaches, thus ensuring a comprehensive prudential framework of the supervisory tools and powers available in the banking, insurance, securities and financial conglomerates directives. The guidelines provided for in Directive 2002/87/EC should reflect the supplementary nature of supervision thereunder, and complement the sector-specific supervision as provided for by Directives 73/239/EEC, 92/49/EEC, 98/78/EC, 2002/83/EC, 2004/39/EC, 2006/48/EC, 2006/49/EC, 2009/138/EC and 2011/61/EU.
