Where, in applying this Directive, the competent authorities of one Member State wish in specific cases to verify the information concerning a credit institution, a financial holding company, a financial institution, an ancillary services undertaking, a mixed-activity holding company, a subsidiary of the kind covered in Article 137 or a subsidiary of the kind covered in Article 127(3), situated in another Member State, they shall ask the competent authorities of that other Member State to have that verification carried out. The authorities which receive such a request shall, within the framework of their competence, act upon it either by carrying out the verification themselves, by allowing the authorities who made the request to carry it out, or by allowing an auditor or expert to carry it out.1 The competent authority which made the request may, if it so wishes, participate in the verification when it does not carry out the verification itself.
