(29)Since the objective of this Directive, namely to harmonise the transparency requirements relating to information about issuers whose securities are admitted to trading on a regulated market, cannot be sufficiently achieved by the Member States and can therefore, by reason of its scale or 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 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 that objective.
