Own funds: a total must equal the sum of its parts (S.23.01, EIOPA rule BV880)

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 "Total" value of the item reported in column "Total" in Own funds (S.23.01) must be equal to the sum of the same item of "Tier 1 - unrestricted", "Tier 1 - restricted", "Tier 2" and "Tier 3"

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 (BV880-3 and BV880-4), 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. 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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

A worked example

The first of its checks, with simple numbers.

Illustrative values
Tier 1 - unrestricted1,200
Tier 1 - restricted800
Tier 2450
Tier 3300
Together2,750
What the rule then expects

Total must then be 2,750.

2,750Passes
2,850Fails

A file that reports 2,750 passes. One that reports 2,850 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.

Which returns it applies to

Line4 Check runs it on quarterly solo (QRS) and quarterly branch (QRB) returns on EIOPA taxonomy 2.10.0. EIOPA applies it to quarterly ECB solo (QES), quarterly solo (QRS), quarterly ECB branch (QEB) and quarterly branch (QRB) returns, as a blocking check.

EIOPA's formula, for BV880-3. Cells are written as {t: table, r: row, c: column}.

{t: S.23.01.02.01, r: R0500, c: C0010, z: Z0001} = {t: S.23.01.02.01, r: R0500, c: C0020, z: Z0001} + {t: S.23.01.02.01, r: R0500, c: C0030, z: Z0001} + {t: S.23.01.02.01, r: R0500, c: C0040, z: Z0001} + {t: S.23.01.02.01, r: R0500, c: C0050, z: Z0001}

BV880-4:

{t: S.23.01.08.01, r: R0500, c: C0010, z: Z0001} = {t: S.23.01.08.01, r: R0500, c: C0020, z: Z0001} + {t: S.23.01.08.01, r: R0500, c: C0030, z: Z0001} + {t: S.23.01.08.01, r: R0500, c: C0040, z: Z0001} + {t: S.23.01.08.01, r: R0500, c: C0050, 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.
