The facts

Who files

How often
Monthly for FIO and SFIO (map line 56); a current report for funds in liquidation. Source

Format
XML. An XML file prepared to KNF's main XSD schema (knf.fi.Kapitaly.xsd) and its supporting schemas (simple, abstract and enumeration types), one file per fund or sub-fund, sent as an attachment to the ESPI form 'PLIKI' to KNF's non-public DFI chancery. Files do not need a signature. KNF publishes an online XML validator, a visualiser and, for some reports, an online form that generates the XML file. Source

  • Changes in capital (ZmianyWKapitale)

Top-level data sections of the main schema knf.fi.Kapitaly.xsd valid from 2024-09 (element names with KNF's Polish labels translated). Markers for a nil report are not counted. Source

Validation rules

4 rules, as counted from the KNF's published material. Software can run them exactly as published. Source

How they are written: XSD 1.1 schema with xs:assert assertions (main schema) and XSD type schemas.

KNF says the main schema defines the XML structure and the business rules that must be met. Files go through several stages of technical and content validation; KNF's online validator checks the first level (conformity with the main schema), and after sending through ESPI the firm receives a technical validation message (file status 'accepted' or 'rejected' and the result of the technical validation rules). A file that fails technical validation must be corrected.

The rules, on sprawozdawczosc.knf.gov.pl

How they were counted

xs:assert elements (XSD 1.1 business rules, each named with a code such as KAPITALY_00001) in the main schema knf.fi.Kapitaly.xsd valid from 2024-09; structure, type and enumeration checks in the supporting schemas are not counted.

Counts are in the KNF's own unit, so they are not comparable with other regulators' counts.
