The rule in plain words

In Detailed information on securitisations by approach (CR SEC Details 2) (C14.01.01.01): "After cap" (column 0440) must equal the sum of "Before cap" (column 0430), "(-) Reduction due to risk weight cap" (column 0431) and "(-) Reduction due to overall cap" (column 0432).

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Add up the parts in your return and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark C14.01.01 as reported.
  6. 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

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:

v7337_m: [C14.01.01.01 (All rows, All sheets)] {c0440} = {c0430} + {c0431} + {c0432}
Show the formulaShow

The Bank of England's formula. Cells are written as {t: table, r: row, c: column}.

{t: C14.01.01.01, c: 0440} = {t: C14.01.01.01, c: 0430} + {t: C14.01.01.01, c: 0431} + {t: C14.01.01.01, c: 0432}

Where it applies, in the Bank's words (its scope):

scope({t: C14.01.01.01, z:0010;0020;0030;0040, f: banking, fv: banking_reporting})
