(8)To ensure equal treatment of managers of collective investment undertakings and to facilitate their decision-making regarding whether to engage in cross-border distribution of investment funds, it is important that fees and charges levied by competent authorities for supervision of cross-border activities are proportionate to the supervisory tasks carried out and publicly disclosed, and that, in order to enhance transparency, those fees and charges are published on the websites of the competent authorities. For the same reason, hyperlinks to the information published on the websites of competent authorities in relation to the fees and charges should be published on the ESMA website in order to have a central point for information. The ESMA website should also include an interactive tool enabling indicative calculations of those fees and charges levied by competent authorities.
