The rule in plain words
total off balance sheet items should equal breakdown of off balance sheet items by conversion buckets
In Credit and counterparty credit risks and free deliveries: IRB approach to capital requirements (CR IRB 1) (OF08.01.01.01): "Total exposures" in column "Of which: off balance sheet items" (row 0010, column 0120) in Credit and counterparty credit risks and free deliveries: IRB approach to capital requirements (CR IRB 1) - Of which arising from counterparty credit risk and off balance sheet (OF08.01.01.02) must equal the sum of "10%" in column "Exposure value" (row 0031, column 0110), "20%" in column "Exposure value" (row 0032, column 0110), "50%" in column "Exposure value" (row 0033, column 0110), "100%" in column "Exposure value" (row 0034, column 0110), "Own estimate" in column "Exposure value" (row 0035, column 0110) and "40%" in column "Exposure value" (row 0001, column 0110).
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- 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 OF08.01.01 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.
Off-balance sheet items subject to credit risk must then be 3,000.
A file that reports 3,000 passes. One that reports 3,100 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 blocking check.
The Bank’s own words and formula
The first paragraph of the plain words above is the Bank of England’s own, word for word, from its list of validations. The second spells out its formula, with each cell named from its templates.
