(104)Since the objectives of this Directive, namely the introduction of rules concerning access to the activity of institutions, and the prudential supervision of institutions, cannot be sufficiently achieved by the Member States and can therefore, by reason of the scale and the effects of the proposed action, be better achieved at Union level, the Union may adopt measures, in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty on European Union. In accordance with the principle of proportionality, as set out in that Article, this Directive does not go beyond what is necessary in order to achieve those objectives.
