Own funds: values must agree (S.23.01, EIOPA rule BV76)

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 "Tier 1 - unrestricted" value of the "Total basic own funds after deductions" reported in Own funds (S.23.01) must be equal to the sum of "Ordinary share capital (gross of own shares)", "Share premium account related to ordinary share capital", "Initial funds, members' contributions or the equivalent basic own - fund item for mutual and mutual-type undertakings", "Surplus funds", "Reconciliation reserve", "Other items approved by supervisory authority as basic own funds not specified above" less "Own funds from the financial statements that should not be represented by the reconciliation reserve and do not meet the criteria to be classified as Solvency II own funds" (as reported in Total) and less "Deductions for participations in other financial undertakings, including non-regulated undertakings carrying out financial activities"

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.

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark S.23.01 as reported.
