Annual update

Third-country auditors and audit entities shall notify the CSSF of any change of information contained in the public register without undue delay from the moment the change occurred.

 
In addition, each year, in January, the CSSF requires all third-country auditors and audit entities to review and to confirm or update their personal data by attaching the required supporting documents.

  
In any case, on an annual basis, all third-country auditors and audit entities are required to submit an updated Client Information List (for transitory or equivalent countries: "Form A-2 (LU)" of "Annex Form A (LU)"; for non-equivalent countries: "Form B-6 (LU)" of "Annex Form B (LU)").
