The rule in plain words
In column "Risk weighted exposure amounts" (0020) of Counterparty credit risk: exposures to CCPs (CCR 10) (C34.10.01.01): "Exposures to QCCPs (total)" (row 0010) must equal the sum of "Exposures for trades at QCCPs (excluding initial margin and default fund contributions); of which" (row 0020), "Non-segregated initial margin" (row 0080), "Prefunded default fund contributions" (row 0090) and "Unfunded default fund contributions" (row 0100).
The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.
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- 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 C34.10.01 as reported.
- 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
The cells it reads
Counterparty credit risk: exposures to CCPs (CCR 10) (C34.10.01.01)
Rows
- R0010Exposures to QCCPs (total)
- R0020Exposures for trades at QCCPs (excluding initial margin and default fund contributions); of which
- R0080Non-segregated initial margin
- R0090Prefunded default fund contributions
- R0100Unfunded default fund contributions
Column
- C0020Risk weighted exposure amounts
A worked example
With simple numbers.
Exposures to QCCPs (total) must then be 2,750.
A file that reports 2,750 passes. One that reports 2,850 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 warning.
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:
v09847_m: [C34.10.01.01 (c0020)] {r0010} = {r0020} + {r0080} + {r0090} + {r0100}
