The "Total" value reported in Own funds should be equal to the sum of "Tier 2" and "Tier 3" (IR.23.01, Bank of England rule IR_bv0840_02)

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

The rule in plain words

The "Total" value reported in Own funds (IR.23.01.04.01) should be equal to the sum of "Tier 2" and "Tier 3"

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.
