The Slovenia Securities Market Agency has issued a technical instruction setting out information system requirements for providers of individual investment accounts (INR), alongside a separate document detailing the functional and technical specifications of the electronic reporting system for all INR providers. The materials are intended as a practical aid, with a particular focus on potential INR providers from other European Union member states that must demonstrate compliance before being entered in the INR provider register. The technical instruction sets minimum functional and technical requirements for providers’ systems to support lawful and uninterrupted operation of INR, reliable record-keeping, reporting and electronic data exchange with the Slovenia Securities Market Agency, and effective supervisory oversight. Systems must be able to produce regular and ad hoc reports within the deadlines, scope and structure specified by the agency, export data at the agency’s request, and enable reporting to the Financial Administration of the Republic of Slovenia; the agency also issued a specification for non-numeric reporting under the Individual Investment Accounts Act. For reporting and electronic data exchange with the agency to be considered established, the provider must obtain an authentication element and an encryption key in line with the functional reporting specification and submit at least one report in the test environment.
