Solvency capital requirement - for undertakings using an internal model (partial or full): a total must equal the sum of its parts (S.25.05, EIOPA rule BV1776)

A warning on the solvency capital requirement - for undertakings using an internal model (partial or full) template (S.25.05), in the annual solo (ARS) and annual branch (ARB) 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 "Solvency Capital Requirement" value reported in S.25.05.01.02 Calculation of Solvency Capital Requirement should be equal to the sum of "Solvency capital requirement, excluding capital add-ons" and "Capital add-ons already set"

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. 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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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.25.05 as reported.
  6. 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

A worked example

With simple numbers.

Illustrative values
Solvency capital requirement, excluding capital add-ons1,200
Capital add-ons already set800
Together2,000
What the rule then expects

Solvency capital requirement must then be 2,000.

2,000Passes
2,100Fails

A file that reports 2,000 passes. One that reports 2,100 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 annual solo (ARS) and annual branch (ARB) returns on EIOPA taxonomy 2.10.0. EIOPA applies it to annual ECB solo (AES), annual ECB branch (AEB), annual solo (ARS) and annual branch (ARB) returns, as a warning.

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. Cells are written as {t: table, r: row, c: column}.

{t: S.25.05.01.02, r: R0220, c: C0100, z: Z0001} = {t: S.25.05.01.02, r: R0200, c: C0100, z: Z0001} + {t: S.25.05.01.02, r: R0210, c: C0100, 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.
