Total eligible own funds to meet the MCR should not be negative (S.23.01, EIOPA rule BV2078)

A warning on the own funds template (S.23.01), in the quarterly solo (QRS) and quarterly branch (QRB) 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

Total eligible own funds to meet the MCR should not be negative

EIOPA writes it out as separate checks, one for each table or return it covers. Line4 Check runs two of them (BV2078-2 and BV2078-4), 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. 02Look for a value below zero in these cells, such as an amount entered as a negative number.
  3. 03It runs only when your filing indicators mark S.23.01 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.
