Own funds: a total must equal the sum of its parts (S.23.01, EIOPA rule BV1769_1)

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

It is new in taxonomy 2.10.0, for returns from the first quarter of 2027. 2.8.2 returns do not have it.

The rule in plain words

The item "Total" value of the "Total basic own funds after deductions" reported in S.23.01 Own funds should be equal to the sum of "Reconciliation reserve", "Subordinated liabilities", and "An amount equal to the value of net deferred tax assets" less "Deductions for participations in financial and credit institutions"

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 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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

EIOPA's formula. Cells are written as {t: table, r: row, c: column}.

{t: S.23.01.08.01, r: R0290, c: C0010, z: Z0001} = {t: S.23.01.08.01, r: R0130, c: C0010, z: Z0001} + {t: S.23.01.08.01, r: R0160, c: C0010, z: Z0001} - {t: S.23.01.08.01, r: R0230, c: C0010, z: Z0001} +{t: S.23.01.08.01, r: R0140, c: C0010, z: Z0001}
