Own funds and annual movements on own funds: two values must match (IR.23.01, IR.23.03, Bank of England rule IR_bv0517)

A blocking check on the own funds (IR.23.01) and annual movements on own funds (IR.23.03) templates, in the quarterly group (QRG) and annual group (ARG) returns.

The rule in plain words

The "Total" value of the item reported in column "Total" reported in Own funds (IR.23.01.04.01) should be equal to the value reported as "Tier 1 - unrestricted"

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 two values must be the same. Find which of the two is right, and correct the other one.
  3. 03It runs only when your filing indicators mark IR.23.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
