Solvency capital requirement - for undertakings on standard formula: rows R0600 to R0690 are not applicable when LAC DT is not used (S.25.01, S.25.05, EIOPA rule BV1078)

A warning on the solvency capital requirement - for undertakings on standard formula (S.25.01) and solvency capital requirement - for undertakings using an internal model (partial or full) (S.25.05) templates, in the annual solo (ARS) 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

Rows R0600 to R0690 are not applicable when LAC DT is not used

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.25.05 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.
