Templates (0)
The library lists no templates for this return.
EU return: the templates and instructions are defined by the EBA. See the library's EBA entry eba/corep-le (docs/eba/corep-le.md). Polish banks use the EBA's templates and taxonomy. Source
Validation rules
The KNF publishes the checks it runs on this return. They could not be counted from the published material. Software can run them exactly as published. Source
How they are written: EBA validation rules in the EBA reporting framework (see the EBA entry).
NBP makes a preliminary check of the reports before passing them to UKNF (KNF bank reporting page); no national checks are published on the KNF pages checked.
How they were counted
Not counted here: the EBA's validation rules apply (see eba/corep-le).
Counts are in the KNF's own unit, so they are not comparable with other regulators' counts.
Public data
No published data from this return was found. No data from this return published by KNF was found on the pages checked. Source

The KNF's own files, with the size and SHA-256 fingerprint of each as downloaded on 11 November 2026, so anyone can tell whether a copy is the same version.
