The rule in plain words
If there are new CREDIT RISK ADJUSTMENTS/WRITE-OFFS for the period, then the observed new defaults must exceed zero
In each of 18 rows (listed below) of Geographical breakdown of exposures by residence of the obligor: IRB exposures (CR GB 2) (OF09.02.01.01): if "Credit risk adjustments/write-offs for observed new defaults" (column 0070) is not zero, every value in "Observed new defaults for the period" (column 0040) must not equal 0.
What to do if your return fails it
- 01Open the table below and find the cells the rule reads.
- 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
- 03It runs only when your filing indicators mark OF09.02.01 as reported.
- 04This 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.
