(8)To assess the functioning of the current national regimes allowing non-EU AIFMs and non-EU AIFs to operate in individual Member States, it is necessary to be fully aware of the details of the legal frameworks adopted by individual Member States, their specificities and differences as compared to the rules applicable to EU AIFMs and EU AIFs. It is also important to gather quantitative information as to the numbers of non-EU AIFs marketed in Member States and non-EU AIFMs managing or marketing AIFs in Member States. Such information should also contain data on enforcement and supervisory actions, as well as on additional information received from non-EU supervisory authorities upon request.
