Update of the Reporting Handbook and new eDesk procedure for IPU threshold monitoring

The CSSF publishes an updated version of the Reporting Handbook for investment firms (v.1.3), which integrates precisions with respect to the requirement to submit final versions of some EU reporting templates and the introduction of the IPU (Intermediate Parent Undertaking) Threshold Monitoring module.

As previously announced via circular email sent to all investment firms on 14 December 2023, the mandatory annual submission by investment firms of the newly introduced IPU threshold monitoring has now entered into force. This IPU reporting aims to verify, on the basis of the total assets of third country groups in the European Union, whether the threshold for establishing an IPU has been exceeded or not (conditions set out in Article 21b of Directive (EU) 2019/878 of the European Parliament and of the Council of 20 May 2019).

Supervised entities that are part of a third country group shall therefore submit to the CSSF the IPU threshold monitoring reporting (U 01.00 template (Annex II)) with reference date 31 December 2023 in XBRL format (see taxonomy established by the EBA), by 12 May 2024 at the latest for the first time. We draw your attention to the fact that U 02.00 template will have to be included with a negative filing indicator (= FALSE).

Please note that the CSSF has opened the data collection of the IPU Threshold monitoring reporting from investment firms belonging to third country groups, on behalf of the EBA, as from 12 March 2024 on.

The Q4 2023 IPU report must be submitted through one of the following channels:

  • Via the submission of the XBRL file in the dedicated eDesk process.
  • Via an API solution (S3 protocol), allowing the flow to be automated.
