Templates (0)

The library lists no templates for this return.

EU templates, defined by EIOPA: see the library's EIOPA entry eiopa/ars (Annual Solvency II return, individual insurer) and, for branches of non-EU insurers, eiopa/arb. Irish firms add the annual national templates (cbi/ins-nst-annual) and the ECB add-ons (cbi/ins-ecb-addons). Source

Validation rules

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

How they are written: Excel list of checks with a formula written in the Central Bank's own row and column notation; not XBRL formulas.

These are the Central Bank's own data quality checks on top of EIOPA's taxonomy rules. The workbook says some (for example missing values) are treated as de facto blocking and others are plausibility checks. EIOPA's own validation rules for the return are counted in the library's EIOPA entry.

The rules, on centralbank.ie

How they were counted

Rows in sheet 'Best Practice Check' of 'Taxonomy 2.8.2 Data Quality Checks 2025' whose 'A and/or Quarters' column includes A (243 marked 'A' and 62 marked 'A,Q').

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

Public data

The Central Bank publishes quarterly balance sheet statistics and annual premiums, claims and acquisition expenses statistics for Irish insurance corporations, derived from the quarterly and annual Solvency II returns (with the statistical NSTs).
