Internal model - non-life and health NSLT underwriting risk and internal model - life and health underwriting risk: a conditional check (S.26.13, S.26.14, EIOPA rule BV1855)

A warning on the internal model - non-life and health NSLT underwriting risk (S.26.13) and internal model - life and health underwriting risk (S.26.14) 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

If the "Mortality and Longevity risk combined aggregate" value of "Net Best Estimate liability + Technical provisions calculated as a whole", "Net Written Premiums" and "Sum insured" reported in S.26.14.01.01 Life and Health underwriting risk - Life SCR and percentiles is reported then "Mortality risk aggregate" and "Longevity risk aggregate" should be empty

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 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.26.14 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.
