(45)Since the objectives of this Directive, namely to improve investor confidence in UCITS by enhancing requirements concerning the duties and the liability of depositaries, the remuneration policies of management companies and investment companies, and by introducing common standards for the sanctions applying to the main infringements of this Directive, cannot be sufficiently achieved by the Member States, but can rather, by reason of their scale and effects, be better achieved at Union level, the Union may adopt measures, in accordance with the principle of subsidiarity as set out in Article 5 TEU. 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.
