Circular CSSF 26/904 — Update of Circular CSSF 24/853 on the Long Form Report and Self-Assessment Questionnaire for Investment Firms

Circular CSSF 26/904 amends Circular CSSF 24/853 by adding four new modules to the self-assessment questionnaire (SAQ) for investment firms: ICT organisation, ICT risk control environment, UCI administration, and marketing, distribution or sale of contracts for differences (CFDs) to retail clients. The circular specifies that the ICT risk control environment module applies only to class 2 and class 3 investment firms not considered microenterprises under DORA, the UCI administration module applies only to firms providing UCI administration activities, and the CFD module applies only to firms marketing, distributing, or selling CFDs to retail clients. Additionally, the list of SAQ modules and their descriptions has been removed from the circular and is now published on the CSSF website.
