Solvency capital requirement - non-life and health catastrophe risk: a total must equal the sum of its parts (S.27.01, EIOPA rule BV302_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 "Catastrophe Risk Charge Credit and Suretyship before risk mitigation/Total before diversification" reported in Solvency Capital Requirement - Non-life and Health catastrophe risk (S.27.01) must be equal to the sum of "Catastrophe Risk Charge Credit and Suretyship before risk mitigation - Large Credit Default/Total" and "Catastrophe Risk Charge Credit and Suretyship before risk mitigation - Recession Risk/Total" reported above

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 (BV302_1-1 and BV302_1-2), 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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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.27.01 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
Total, Catastrophe Risk Charge Credit and Suretyship before risk mitigation - Large Credit Default1,200
Total, Catastrophe Risk Charge Credit and Suretyship before risk mitigation - Recession Risk800
Together2,000
What the rule then expects

Total before diversification, Catastrophe Risk Charge Credit and Suretyship before risk mitigation 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), annual group (ARG) and annual branch (ARB) returns on EIOPA taxonomy 2.10.0. EIOPA applies it to annual branch (ARB), annual solo (ARS), annual ECB solo (AES), annual ECB branch (AEB) and annual group (ARG) returns, as a blocking check.

EIOPA’s own words and formula

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

The item "Catastrophe Risk Charge Credit and Suretyship before risk mitigation/Total before diversification" reported in S.27.01 - Solvency Capital Requirement - Non-life and Health catastrophe risk must be equal to the sum of "Catastrophe Risk Charge Credit and Suretyship before risk mitigation - Large Credit Default/Total" and "Catastrophe Risk Charge Credit and Suretyship before risk mitigation - Recession Risk/Total" reported above.

EIOPA's formula, for BV302_1-1. Cells are written as {t: table, r: row, c: column}.

{t: S.27.01.01.18, r: R3100, c: C1100, z: Z0001} = {t: S.27.01.01.16, r: R2920, c: C1010, z: Z0001} + {t: S.27.01.01.17, r: R3000, c: C1060, z: Z0001}

BV302_1-2:

{t: S.27.01.04.18, r: R3100, c: C1100, z: Z0001} = {t: S.27.01.04.16, r: R2920, c: C1010, z: Z0001} + {t: S.27.01.04.17, r: R3000, c: C1060, 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.
