The Slovenia Securities Market Agency adopted two general acts under the Investment Funds and Management Companies Act (ZISDU-3), one setting key elements and a more granular typology for investment funds and another establishing detailed reporting requirements for management companies, including management companies from other Member States. The act on key elements of an investment fund and the types and categories of investment funds sets the core criteria a collective investment undertaking must meet, specifies more detailed types of collective investment undertakings investing in transferable securities (KNPVP) by general investment characteristics, and standardises the classification and naming of KNPVP categories based on investment features and asset management techniques used for efficient investment management. It also defines “additional liquid assets”, including their types and characteristics, how their size is determined, how they relate to other mutual fund assets, and the maximum permitted level. The reporting act sets the content, format and deadlines for disclosures to the Agency on qualifying holders of a management company, capital adequacy, outsourcing or transfers of specific services or fund management activities and changes to transfer agreements, changes to a fund’s risk management plan, information required under Article 187(5) of ZISDU-3, and regular and on-request reporting under Articles 454 to 456 of ZISDU-3. Both acts enter into force on the fifteenth day after publication in the Official Gazette of the Republic of Slovenia, while the reporting act applies from 1 December 2025.
