What is meant with 'mainly' in the definition of 'financial holding company'?

The term "mainly" used in Article 4(1)(20) of Regulation (EU) No 575/2013 should be understood to refer to a situation where more than 50% of the equity, consolidated assets, revenues, personnel or another indicator deemed relevant by the competent authority of a holding company are associated with subsidiaries that are institutions or financial institutions.   DISCLAIMER: This question goes beyond matters of consistent and effective application of the regulatory framework. A Directorate General of the Commission (Directorate General Financial Stability, Financial Services and Capital Markets Union) 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.
