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"

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Add up the parts in your return and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark IR.23.01 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

What the rule then expects

Total must then be 2,000.

2,000Passes
2,100Fails

A file that reports 2,000 passes. One that reports 2,100 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.
