Own funds: a value must not be less than another (S.23.01, EIOPA rule BV889)

A blocking check on the own funds template (S.23.01), in the quarterly solo (QRS) and quarterly branch (QRB) 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 basic own funds after deductions Tier 1 restricted" must be equal or higher than "Total eligible own funds to meet the MCR Tier 1 restricted"

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.

EIOPA writes it out as separate checks, one for each table or return it covers. Line4 Check runs two of them (BV889-3 and BV889-4), and a failure names the one that failed.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is smaller than it may be, one of them is wrong: check both before you change either.
  3. 03It runs only when your filing indicators mark S.23.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

EIOPA’s own words and formula

The plain words above are EIOPA’s own, word for word, from its list of validations.

EIOPA's formula, for BV889-3. Cells are written as {t: table, r: row, c: column}.

{t: S.23.01.02.01, r: R0290, c: C0030, z: Z0001} >= {t: S.23.01.02.01, r: R0500, c: C0030, z: Z0001}

BV889-4:

{t: S.23.01.08.01, r: R0290, c: C0030, z: Z0001} >= {t: S.23.01.08.01, r: R0550, c: C0030, 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.
