(12)In the Union, collective investment undertakings can operate as UCITS, managed by UCITS management companies or UCITS investment companies authorised under Directive 2009/65/EC, or as AIFs, managed by alternative investment fund managers (AIFMs) authorised or registered under Directive 2011/61/EU. The new rules on MMFs build on the existing legal framework established by those Directives, including the acts adopted for their implementation, and should therefore apply in addition to those Directives. Furthermore, the management and marketing rules laid down in the existing legal framework should apply to MMFs taking into account whether they are UCITS or AIFs. Equally, the rules on the cross-border provision of services and freedom of establishment laid down in Directives 2009/65/EC and 2011/61/EU should apply correspondingly to the cross-border activities of MMFs. At the same time, a number of rules in relation to the investment policies of UCITS laid down in Chapter VII of Directive 2009/65/EC should be explicitly disapplied.
