This report provides and assesses evidence for the European Commission's review of AIFMD pursuant to Article 69 AIFMD. The assessment of this study is focused on 15 selected Member States. It consists of two main sections. The general survey among AIFMs, NCAs and other stakeholders asked questions about specific aspects of AIFMD and market developments. The evidence-based study was based on desk research, the general survey results, interviews, and quantitative data collection and analysis. On the basis of the evidence retrieved and analysis undertaken, AIFMD has played a major role in helping to create an internal market for AIFs and a harmonised and stringent regulatory and supervisory framework for AIFMs. Most areas of the provisions are assessed as having contributed to achievement of the general, specific and operational objectives, to have done so effectively, efficiently and coherently, to remain relevant and to have EU added value. There are, however, aspects that have not contributed, or may be counter to, the achievement of these aims - particularly, but not exclusively, in relation to the principles of effectiveness and efficiency.
