Counterparty credit risk: CCR exposures by approach (CCR 2): "Total" must not be less than "Of which: SWWR positions" (C34.02.01.01, Bank of England check v09810_m)

A warning on the counterparty credit risk: CCR exposures by approach (CCR 2) template (C34.02.01.01), in the own funds (PRA001) return.

Line4 Check runs it on the own funds (PRA001) return, proven on test files, check by check: the same outcome on all three test files of that return.

The rule in plain words

In each of 6 columns (listed below) of Counterparty credit risk: CCR exposures by approach (CCR 2) (C34.02.01.01): "Total" (row 0110) must not be less than "Of which: SWWR positions" (row 0120).

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is smaller than it may be, one of them is wrong: check both before you change either.
  3. 03The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark C34.02.01 as reported.
  5. 05This 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:

v09810_m: [C34.02.01.01 (c0020;0030;0040;0160;0170;0200, All sheets)] {r0110} >= {r0120}

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

{t: C34.02.01.01, r: 0110} >= {t: C34.02.01.01, r: 0120}

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

scope({t: C34.02.01.01, c:0020;0030;0040;0160;0170;0200,z:0001;0002, 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.
