eDesk/S3 communication means only applicable for AIFM reporting

As of 1 July 2024, the Commission de Surveillance du Secteur Financier (CSSF) has mandated that all Alternative Investment Fund Managers (AIFMs) submit their regulatory reports exclusively through two approved channels: the eDesk platform or the API interface (S3 technology). This update marks the discontinuation of previous external transmission methods, which will no longer be processed by the CSSF.

This change follows earlier announcements:

• From 2 November 2023, AIFMs could transmit reports via the API interface.

• From 31 January 2024, the eDesk procedure became available for reporting submissions.

The CSSF's AIFM Reporting – Technical Guidance (Version 1.7, July 2024) provides detailed instructions on the content and structure of the required XML files, including specifications for both AIFM and AIF reporting files. It also outlines the procedures for registration as a sender and the interpretation of feedback files, which include error codes and messages to assist in compliance.

For further information or assistance, AIFMs are encouraged to consult the Technical Guidance document or contact the CSSF directly at edesk@cssf.lu.
