Own funds and list of items on own funds: values must agree (IR.23.01, IR.23.04, Bank of England rule IR_bv0835)

A blocking check on the own funds (IR.23.01) and list of items on own funds (IR.23.04) templates, in the quarterly group (QRG) and annual group (ARG) returns.

Check your file for this rule

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 sum of the same item of "Tier 1 - unrestricted", "Tier 1 - restricted", "Tier 2" and "Tier 3"

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.23.01 as reported.
