(48)At present, Regulation (EU) 2015/760 requires investors to be treated equally and prohibits preferential treatment of individual investors or groups of investors, or the granting of specific economic benefits to those investors. ELTIFs can, however, have several classes of units or shares with slightly or substantially distinct conditions as regards the fees, legal structure, marketing rules and other requirements. In order to take those differences into account, those requirements should only apply to individual investors or groups of investors that invest in the same class or classes of ELTIFs.
