(54)In order to take account of future changes to the laws of the Member States and to Union legislation concerning company types, the Commission should be empowered to adopt delegated acts in accordance with Article 290 of the TFEU in order to update the lists of undertakings contained in Annexes I and II. The use of delegated acts is also necessary in order to adapt the undertaking size criteria, as with the passage of time inflation will erode their real value. It is of particular importance that the Commission carry out appropriate consultations during its preparatory work, including at expert level. The Commission, when preparing and drawing up delegated acts, should ensure a simultaneous, timely and appropriate transmission of relevant documents to the European Parliament and to the Council.
