The item "Total ancillary own funds" for "Tier 3" reported in Own funds must be equal to the sum of the items reported above (S.23.01, EIOPA rule BV84)

A blocking check on the own funds template (S.23.01), in the quarterly solo (QRS) return.

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

The item "Total ancillary own funds" for "Tier 3" reported in Own funds (S.23.01) must be equal to the sum of the items reported above

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Add up the parts in your return and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04EIOPA allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark S.23.01 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

What the rule then expects

Total ancillary own funds must then be 2,900.

2,900Passes
3,000Fails

A file that reports 2,900 passes. One that reports 3,000 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.

Which returns it applies to

Line4 Check runs it on quarterly solo (QRS) return on EIOPA taxonomy 2.10.0. EIOPA applies it to quarterly ECB solo (QES) and quarterly solo (QRS) returns, as a blocking check.
