Detailed information by tiers on own funds: two values must match (S.23.02, EIOPA rule BV115)

A blocking check on the detailed information by tiers on own funds template (S.23.02), 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 "Total Tier 1" 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 "Total Tier 1" value of "Initial fund members' contributions or the equivalent basic own fund item for mutual and mutual type undertakings"

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 table 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.

A worked example

With simple numbers.

Illustrative values
Paid in1,200
What the rule then expects

Total initial fund members' contributions or the equivalent basic own fund item for mutual and mutual type undertakings 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: R0110, 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.
