1 min readWarningBank of England taxonomy 2.2.0Updated 11 November 2026

Balance sheet and detailed information by tiers on own funds: values must agree (IR.02.01, IR.23.02, Bank of England rule IR_bv0682)

A warning on the balance sheet (IR.02.01) and detailed information by tiers on own funds (IR.23.02) templates, in the annual group (ARG) return.

The rule in plain words

Item "Difference in the valuation of assets" is different from the difference between the "Solvency II value" and "Statutory accounts value" of "Total Assets" in 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 warning. It does not stop the return on its own, but your supervisor may ask you to explain it. It runs only when your filing indicators mark IR.02.01 and IR.23.02 as reported.
