Content of the submission and solvency capital requirement - for undertakings using an internal model (partial or full): a conditional check (S.01.01, S.25.05, EIOPA rule BV1742_1)

A blocking check on the content of the submission (S.01.01) and solvency capital requirement - for undertakings using an internal model (partial or full) (S.25.05) 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 amount/estimate of the loss-absorbing capacity for deferred taxes reported in Solvency Capital Requirement (S.25.05) - for undertakings using partial internal model must be lower or equal to zero

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. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03It runs only when your filing indicators mark S.01.01 and S.25.05 as reported.
  4. 04This 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}.

if {t: S.01.01.01.01, r: R0470, c: C0010} = [s2c_CN:x80] then {t: S.25.05.01.02, r: R0310, c: C0100, z: Z0001} <= 0 else true()

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.
