Solvency capital requirement - life underwriting risk: a conditional check (S.26.03, EIOPA rule BV578_1)

A blocking check on the solvency capital requirement - life underwriting risk template (S.26.03), 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 the solvency capital requirement must be reported in Solvency Capital Requirement - Life underwriting risk (S.26.03) for longevity risk when the simplification on longevity 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 (BV578_1-3 and BV578_1-4), 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.26.03 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

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.
