Templates (0)

The library lists no templates for this return.

EU templates, defined by EIOPA: see the library's EIOPA entry eiopa/arg (docs/eiopa/arg.md). Dutch insurers add DNB's national templates (dnb/ins-national-annual and related returns) where they apply. Source

Validation rules

677 rules, as counted from the DNB's published material. They are written for people to read; software cannot run them as published. Source

How they are written: Excel list of DNB's additional checks with pseudo code and formulas in DNB's own notation (rule type P plausibility or C consistency).

These are DNB's checks on top of EIOPA's taxonomy rules (see eiopa/arg).

The rules, on dnb.nl

How they were counted

Active rows in DNB's 'Aanvullende controleregels' workbook (23 December 2025) whose Entrypoint column is S2ARG; EIOPA's own rules are counted in the library's EIOPA entry.

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

Public data

Published firm by firm. DNB publishes table 7.17 'Data individual insurer groups' (Solvency II, yearly). Source
