(4)Regulation (EU) 2019/1156 further strengthens the principles applicable to marketing communications governed by Directive 2009/65/EC and extends the application of those principles to AIFMs, thereby resulting in a high standard of investor protection, regardless of the type of investor. The corresponding provisions of Directive 2009/65/EC relating to marketing communications and accessibility of national laws and regulations relevant to the arrangement of marketing units of UCITS are therefore no longer necessary and should be deleted.
