Premiums, claims and expenses by line of business and solvency capital requirement - non-Life underwriting risk: a conditional check (S.05.01, S.26.05, EIOPA rule BV674)

A warning on the premiums, claims and expenses by line of business (S.05.01) and solvency capital requirement - non-Life underwriting risk (S.26.05) templates, 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

Only premiums volume, reserves volume and total volume should be reported in Solvency Capital Requirement - Non-Life underwriting risk (S.26.05) for marine, aviation and transport insurance when the simplification on premium and reserve risk is applied

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 (BV674-1 and BV674-2), 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. 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.05.01 and S.26.05 as reported.
  4. 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

Every Solvency II rule on S.05.01

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.
