(27)Different governance structures are used across Member States. In most cases a unitary or a dual‐board structure is used. The definitions laid down in this Directive are intended to embrace all existing structures without expressing a preference for any particular structure. They are purely functional for the purpose of setting out rules aimed at a particular outcome irrespective of the national company law applicable to an institution in each Member State. The definitions should therefore not interfere with the general allocation of competences in accordance with national company law.
