Balance sheet and own funds: values must agree (IR.02.01, IR.23.01, Bank of England rule IR_bv0837)

A blocking check on the balance sheet (IR.02.01) and own funds (IR.23.01) templates, in the annual group (ARG) return.

The rule in plain words

The "Total" value of "Reconciliation Reserve/Other basic own fund items" figure reported into the template Own funds (IR.23.01) should be equal to the sum of item "Ordinary share capital (gross of own shares)", "Share premium account related to ordinary share capital"," Initial funds, members' contributions or the equivalent basic own funds item for mutual and mutual type undertakings", "Subordinated mutual members accounts", "Surplus funds", "Preference shares", "Share premium account related to preference shares", "Equity- and liability-accounted subordinated instruments", "An amount equal to the value of net deferred tax assets", "Other own fund items approved by the supervisory authority as basic own funds not specified above" and "Minority interests", minus "Subordinated liabilities in Basic Own Funds" as reported into IR.02.01

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 IR.02.01 and IR.23.01 as reported.
