(17)It is important that UCITS and AIFs that have the characteristics of MMFs be identified as MMFs and that their capacity to comply on an ongoing basis with the new uniform rules on MMFs be explicitly verified. For that purpose, competent authorities should authorise MMFs. For UCITS, their authorisation as MMFs should be part of the authorisation as UCITS in accordance with the harmonised procedures under Directive 2009/65/EC. For AIFs, as they are not subject to harmonised authorisation and supervision procedures under Directive 2011/61/EU, it is necessary to provide for common basic rules on authorisation that mirror the existing harmonised rules for UCITS. Such procedures should ensure that the manager of an AIF authorised as an MMF is an AIFM authorised in accordance with Directive 2011/61/EU.
