The rule in plain words
In column "Amount" (0010) of Own funds (CA1) (C01.00.01.01): "(-) Own AT1 instruments" (row 0580) must equal the sum of "(-) Direct holdings of AT1 instruments" (row 0590), "(-) Indirect holdings of AT1 instruments" (row 0620) and "(-) Synthetic holdings of AT1 instruments" (row 0621).
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
- 01Open the tables below and find the cells the rule reads.
- 02Add up the parts in your return and compare the result with the total.
- 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
- 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
- 05It runs only when your filing indicators mark C01.00.01 as reported.
- 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

A worked example
With simple numbers.
(-) Own AT1 instruments must then be 2,450.
A file that reports 2,450 passes. One that reports 2,550 fails, by 100.
The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.
Which returns it applies to
Line4 Check runs it on the own funds (PRA001) and own funds for SDDTs (PRA116) returns on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to own funds for SDDTs (PRA116) and own funds (PRA001) returns, as a blocking check.
The Bank’s own words and formula
The plain words above spell out the Bank’s formula, with each cell named from its templates. In the Bank of England’s list of validations, word for word:
v0184_m: [C01.00.01.01] {r0580, c0010} = {r0590, c0010} + {r0620, c0010} + {r0621, c0010}
