The rule in plain words
Total Corporates exposures shall add up to the individual Corporates breakdowns
In each of 12 columns (listed below) of Geographical breakdown of exposures by residence of the obligor: IRB exposures (CR GB 2) (OF09.02.01.01): "Corporates" (row 0030) must equal the sum of 6 rows (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- 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 OF09.02.01 as reported.
- 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

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.

The Bank of England's formula. Cells are written as {t: table, r: row, c: column}.
{t: OF09.02.01.01, r: 0030} = sum({t: OF09.02.01.01, r: 0042; 0045; 0048; 0049; 0050; 0055})Where it applies, in the Bank's words (its scope):
scope({t: OF09.02.01.01, c:0010;0030;0040;0050;0055;0060;0070;0105;0107;0110;0120;0130, f: banking, fv: banking_reporting})Other rules on Geographical breakdown of exposures by residence of the obligor: IRB exposures (CR GB 2) (OF09.02.01.01)

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.
