Own funds and detailed information by tiers on own funds: two values must match (S.23.01, S.23.02, EIOPA rule BV116)

A blocking check on the own funds (S.23.01) and detailed information by tiers on own funds (S.23.02) templates, in the annual group (ARG) return.

It applies to 2.8.2 returns too, the release for the 2026 returns, and Line4 Check runs it there as well.

The rule in plain words

The "Tier 2" value of "Total initial fund members' contributions or the equivalent basic own fund item for mutual and mutual type undertakings" reported in Detailed information by tiers on own funds (S.23.02) must be equal to the "Tier 2" value of "Initial fund members' contributions or the equivalent basic own fund item for mutual and mutual type undertakings/Called up but not yet paid in"

The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02The two values must be the same. Find which of the two is right, and correct the other one.
  3. 03It runs only when your filing indicators mark S.23.02 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The cells it reads

A worked example

With simple numbers.

Illustrative values
Called up but not yet paid in, Tier 21,200
What the rule then expects

Initial funds, members' contributions or the equivalent basic own - fund item for mutual and mutual-type undertakings, Tier 2 must then be 1,200.

1,200Passes
1,300Fails

A file that reports 1,200 passes. One that reports 1,300 fails, by 100.

The numbers are illustrative.

Which returns it applies to

Line4 Check runs it on annual group (ARG) return on EIOPA taxonomy 2.10.0. EIOPA applies it to annual group (ARG) returns, as a blocking check.

EIOPA's formula. Cells are written as {t: table, r: row, c: column}.

{t: S.23.02.04.01, r: R0200, z: Z0001} = {t: S.23.02.04.01, r: R0120, z: Z0001}

Checks like this one, run at the point of submission, are the first step to real-time supervision. Line4 builds SupTech software for financial regulators that runs checks like these as each return arrives.
