Solvency capital requirement - non-life and health catastrophe risk: values must agree (S.27.01, EIOPA rule BV279_1)

A blocking check on the solvency capital requirement - non-life and health catastrophe risk template (S.27.01), in the annual solo (ARS), annual group (ARG) 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 item "Diversification effect between regions" reported in Solvency Capital Requirement - Non-life and Health catastrophe risk (S.27.01) must be equal to the difference between "Total Flood after diversification" and "Total Flood all Regions before diversification"

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 (BV279_1-1 and BV279_1-2), 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.27.01 as reported.

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

EIOPA's formula, for BV279_1-1. Cells are written as {t: table, r: row, c: column}.

{t: S.27.01.01.04, r: R1610, z: Z0001} = {t: S.27.01.01.04, r: R1620, z: Z0001} - {t: S.27.01.01.04, r: R1600, z: Z0001}

BV279_1-2:

{t: S.27.01.04.04, r: R1610, z: Z0001} = {t: S.27.01.04.04, r: R1620, z: Z0001} - {t: S.27.01.04.04, r: R1600, z: Z0001}

Every Solvency II rule on S.27.01

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.
