(74)In order to allow for the effective oversight of and, where necessary, enforcement of this Directive in relation to third-country companies, those companies should designate a sufficiently mandated authorised representative in the Union and provide information relating to their authorised representatives. It should be possible for the authorised representative to also function as a point of contact, provided the relevant requirements of this Directive are complied with. If the third-country company does not designate the authorised representative, all Member States in which the company operates should be competent to enforce the fulfilment of this obligation, especially to designate a natural or legal person in one of the Member States where it operates, in accordance with the enforcement framework set in national law. The Member States initiating such enforcement should inform supervisory authorities of other Member States through a European Network of Supervisory Authorities so that other Member States do not enforce them.
