The value reported in column "Total" reported in Own funds should be equal to the value reported as "Tier 3" (IR.23.01, Bank of England rule IR_bv0518)

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 value reported in column "Total" reported in Own funds (IR.23.01.04.01) should be equal to the value reported as "Tier 3"

What to do if your return fails it

  1. 01Open the table 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.

The cells it reads

Own funds (IR.23.01.04.01)

Row

  • R0170The amount equal to the value of net deferred tax assets not available at the group level

Columns

  • C0010Total
  • C0050Tier 3

A worked example

With simple numbers.

Illustrative values
Tier 31,200
What the rule then expects

Total must then be 1,200.

1,200Passes
1,300Fails

A file that reports 1,200 passes. One that reports 1,300 fails, by 100.

The numbers are illustrative.
