The calculation of the supplementary capital adequacy requirements of the regulated entities in a financial conglomerate referred to in Article 6(1) shall be carried out in accordance with the technical principles and one of the methods described in this Annex.

Without prejudice to the provisions of the next paragraph, Member States shall allow their competent authorities, where they assume the role of coordinator with regard to a particular financial conglomerate, to decide, after consultation with the other relevant competent authorities and the conglomerate itself, which method shall be applied by that financial conglomerate.

Member States may require that the calculation be carried out according to one particular method among those described in this Annex if a financial conglomerate is headed by a regulated entity which has been authorised in that Member State. Where a financial conglomerate is not headed by a regulated entity within the meaning of Article 1, Member States shall authorise the application of any of the methods described in this Annex, except in situations where the relevant competent authorities are located in the same Member State, in which case that Member State may require the application of one of the methods.
