Legal reporting encompasses all the periodic and ad hoc information to be transmitted to the CSSF for prudential supervisory purposes by the entities under its supervision, observing the file transport and data protection instructions.

The supervised entities are required to transmit periodic data relating to their activities to the CSSF on a monthly, quarterly, half-yearly or annual basis, depending on the circumstances.

The CSSF instructions only concern the prudential reporting (tables O, U, SIAG and MMF), for which the CSSF is responsible. Instructions relating to the statistical reporting (tables S), for which the BCL is responsible, are available on the BCL website .

It should be borne in mind that the tables O, U and S are shared between the CSSF and the BCL.

The page File transport and data protection provides additional technical details regarding the transmission channels for reporting.
