The rule in plain words
In each of "Derivatives with positive fair value - Carrying amount" (column 0270) and "Derivatives with negative fair value - Carrying amount" (column 0280) of General governments exposures by country of the counterparty and regulatory approach (Gov) (C33.00.01.02): "Total exposures" (row 0010) must equal the sum of 7 cells (listed below).
What to do if your return fails it
- 01Open the table 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- 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 C33.00.01 as reported.
- 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

A worked example
With simple numbers.
Total exposures must then be 3,060.
A file that reports 3,060 passes. One that reports 3,160 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) return on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to own funds (PRA001) returns, as a warning.
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:
[v10718_m];[scope({t: C33.00.01.02, c:0270;0280})];[{t: C33.00.01.02, r: 0010} = {t: C33.00.01.02, r: 0170} + {t: C33.00.01.02, r: 0180} + {t: C33.00.01.02, r: 0190} + {t: C33.00.01.02, r: 0200} + {t: C33.00.01.02, r: 0210} + {t: C33.00.01.02, r: 0220} + {t: C33.00.01.02, r: 0230}]

{t: C33.00.01.02, r: 0010} = {t: C33.00.01.02, r: 0170} + {t: C33.00.01.02, r: 0180} + {t: C33.00.01.02, r: 0190} + {t: C33.00.01.02, r: 0200} + {t: C33.00.01.02, r: 0210} + {t: C33.00.01.02, r: 0220} + {t: C33.00.01.02, r: 0230}Where it applies, in the Bank's words (its scope):
scope({t: C33.00.01.02, c:0270;0280, f: banking, fv: banking_reporting})Checks like this one, run at the point of submission, are the first step to real-time supervision. Line4 builds SupTech software for financial regulators that runs checks like these as each return arrives.
