Own funds: two values must match (S.23.01, EIOPA rule BV530)

A blocking check on the own funds template (S.23.01), in the quarterly branch (QRB) 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" value of the item reported in column "Total" reported in Own funds (S.23.01) must be equal to the value reported as "Tier 1 - unrestricted"

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.23.01 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

Own funds (S.23.01.08.01)

Row

  • R0130Reconciliation reserve

Columns

  • C0010Total
  • C0020Tier 1 - unrestricted

A worked example

With simple numbers.

Illustrative values
Tier 1 - unrestricted1,200
What the rule then expects

Total 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 quarterly branch (QRB) return on EIOPA taxonomy 2.10.0. EIOPA applies it to quarterly ECB branch (QEB) and quarterly branch (QRB) returns, as a blocking check.

EIOPA’s own words and formula

In EIOPA’s list of validations, word for word:

The "Total" value of the item reported in column "Total" reported in S.23.01 - Own funds must be equal to the value reported as "Tier 1 - unrestricted".

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

{t: S.23.01.08.01, c: C0010, z: Z0001} = {t: S.23.01.08.01, c: C0020, z: Z0001}

Every Solvency II rule on S.23.01

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.
