The French Autorité des Marchés Financiers (AMF) issued Instruction DOC-2017-05 to define the procedures for implementing redemption suspension mechanisms and cost-compensation tools within UCITS, AIFs, and various specialized investment funds. These measures are designed to mitigate portfolio restructuring costs borne by shareholders during subscription and redemption periods, thereby ensuring fair treatment of all investors. The instruction aligns with specific articles of the French Monetary and Financial Code and the AMF's General Regulation.
