Own funds and list of items on own funds: a total must equal the sum of its parts (S.23.01, S.23.04, EIOPA rule BV878)

A blocking check on the own funds (S.23.01) and list of items on own funds (S.23.04) templates, in the annual solo (ARS) 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 value of "Own funds from the financial statements that should not be represented by the reconciliation reserve and do not meet the criteria to be classified as Solvency II own funds" reported in template Own funds (S.23.01) must be equal to the sum of the values reported in template Own funds from the financial statements that should not be represented by the reconciliation reserve and do not meet the criteria to be classified as Solvency II own funds (S.23.04.01.05)

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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.23.01 and S.23.04 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

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

sum({t: S.23.04.01.05, c: C0580}) = {t: S.23.01.01.01, r: R0220, c: C0010, 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.
