The facts

Who files
FIO and SFIO (map line 64, § 13 ust. 1 pkt 6 lit. b). Source
How often
Quarterly (map line 64). Source
Deadline
By the last day of the month after the end of the quarter, and 35 days after the opening of liquidation (map line 64). Source
Format
XML. An XML file prepared to KNF's main XSD schema (knf.fi.Uczestnicy.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
How it is filed
Filing routes recorded for the KNF: ESPI (Elektroniczny System Przekazywania Informacji, Electronic Information Transmission System); Portal KNF (KNF Portal), with the Data Transmission Application (ATD); WebService KNF; CRP communication subsystem (Podsystem Komunikacji CRP), including the DORA Reporting System (SSD); e-RUP reporting forms; Aplikacja Sprawozdawcza SNU (Reporting Application); NBP SIS (reporting system of Narodowy Bank Polski).

  • Fund participants (Uczestnicy)

Top-level data sections of the main schema knf.fi.Uczestnicy.xsd valid from 2025-01 (element names with KNF's Polish labels translated). Markers for a nil report are not counted. Source

Validation rules

0 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

The main schema knf.fi.Uczestnicy.xsd valid from 2025-01 contains no xs:assert business rules; only its structure, type and enumeration checks apply.

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