2 min readWarningEIOPA taxonomy 2.10.0Updated 11 November 2026

Participations held: a total must equal the sum of its parts (S.24.01, EIOPA rule BV1613)

A warning on the participations held template (S.24.01), in the annual solo (ARS) and annual branch (ARB) returns.

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 item "Total all participations" reported in S.24.01, should be equal to the sum of the total "Total participations in related undertakings that are financial and credit institutions (for which there is an OF deduction)" and total participations reported in tables 3, 4, 5, 6, 7

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. 02Add up the parts in your return and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04EIOPA allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark S.24.01 as reported.
  6. 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

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.
