(23)To cover material infringements of prudential requirements, it is necessary to further specify the conditions for determining that holding companies are failing or are likely to fail. An infringement of those requirements by a holding company should be material where the type and extent of such infringement is comparable with an infringement that, if committed by a credit institution, would justify the withdrawal of the authorisation by the competent authority in accordance with Article 18 of Directive 2013/36/EU.
