The Reserved Alternative Investment Fund (Raif) is a new investment vehicle launched in Luxembourg that provides greater flexibility and speed to market compared to traditional regulated fund structures. The Raif does not require prior authorization or ongoing approval from Luxembourg's financial regulator (CSSF). It is still subject to depositary, administration and audit requirements. While not directly regulated, the Raif provides investor protections as it must be managed by an authorized Alternative Investment Fund Manager (AIFM) that is regulated. The Raif is expected to attract interest from managers looking for a more flexible solution than traditional regulated funds, while still providing the operational characteristics and reporting of regulated funds.
