Own funds: values must agree (S.23.01, EIOPA rule BV542)

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 "Tier 1 - restricted" value of "Available and eligible own funds/Total eligible own funds to meet the SCR" reported into the template Own funds (S.23.01) must be the minimum between 25% of "Total eligible own funds to meet the SCR/Tier 1 - unrestricted" and "Total eligible own funds to meet the SCR/Tier 1 - restricted" when "Tier 1 - unrestricted" value of "Available and eligible own funds/Total eligible own funds to meet the SCR" is greater then 0

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 (BV542-3 and BV542-4), and a failure names the one that failed.

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark S.23.01 as reported.

EIOPA's formula, for BV542-3. Cells are written as {t: table, r: row, c: column}.

{t: S.23.01.02.01, r: R0540, c: C0030, z: Z0001} = min(max({t: S.23.01.02.01, r: R0540, c: C0020, z: Z0001}, 0) * 0.25, {t: S.23.01.02.01, r: R0500, c: C0030, z: Z0001})

BV542-4:

{t: S.23.01.08.01, r: R0540, c: C0030, z: Z0001} = min(max({t: S.23.01.08.01, r: R0540, c: C0020, z: Z0001}, 0) * 0.25, {t: S.23.01.08.01, r: R0500, 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.
