New U1.1 reporting transmission procedures

As announced in the 5 April 2024 communication regarding the direct submission of filings to the CSSF, the methods for transmitting U1.1 reports will change from 15 November 2024.

The expected reports may be transmitted using the following methods:

  • A dedicated eDesk procedure
  • An API solution based on the submission of XML reports via the S3 protocol

A user guide detailing the submission procedures for the U1.1 reports will be made available soon.

Please note that it will still be possible to transmit U1.1 reports via external transmission channels until 28 February 2025.

For any questions, please contact edesk@cssf.lu.
