1 min readWarningBank of England taxonomy 2.2.0Updated 11 November 2026

Own funds and 2 other templates: a conditional check (IR.23.01, IR.23.03, IR.23.02, Bank of England rule IR_bv1758_01)

A warning on the own funds (IR.23.01), annual movements on own funds (IR.23.03) and detailed information by tiers on own funds (IR.23.02) templates, in the annual solo (ARS) return.

The rule in plain words

The item "Balance brought forward" should be reported in Annual movements on own funds (IR.23.03.01.02). If the balance is yet unknown the balance should be filled with zero

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 tables below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03It runs only when your filing indicators mark IR.23.03 as reported.
  4. 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
