Credit and counterparty credit risks and free deliveries: standardised approach to capital requirements (CR SA): a total must equal the sum of its parts (OF07.00.01.01, OF09.01.01.01, OF02.00.01.01 and others, Bank of England check boe_b0703)

A warning on the credit and counterparty credit risks and free deliveries: standardised approach to capital requirements (CR SA) (OF07.00.01.01), geographical breakdown of exposures by residence of the obligor: SA exposures (OF CR GB 1) (OF09.01.01.01), own funds requirements (CA2) (OF02.00.01.01), credit and counterparty credit risks and free deliveries: standardised approach to capital requirements for SDDTs (CR SA SDDT) (SC07.00.01.01), geographical breakdown of exposures by residence of the obligor (SA EXPOSURES) (CR GB 1) (SC09.01.01.01) and own funds requirements for SDDTs (CA2 SDDT) (SC02.00.01.01) templates, in the own funds (PRA001) and own funds for SDDTs (PRA116) returns.

Line4 Check runs it on the own funds (PRA001) and own funds for SDDTs (PRA116) returns, proven on test files, check by check: the same outcome on all six test files of those returns.

Check your file for this ruleWhat to do if it fails

The rule in plain words

the two types of determinants for Risk Weighted Exposure Amounts (of which columns) sum up to total risk weighted exposure amounts for the relevant row

In each of 41 rows (listed below) of Credit and counterparty credit risks and free deliveries: standardised approach to capital requirements (CR SA) (OF07.00.01.01): "Risk-weighted exposure amount" (column 0220) must equal the sum of "Of which: with a credit assessment by a nominated ECAI" (column 0230) and "Of which: where a credit assessment by a nominated ECAI is not available" (column 0235).

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

  1. 01Open the tables 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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 OF07.00.01 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.

Which returns it applies to

Line4 Check runs it on the own funds (PRA001) and own funds for SDDTs (PRA116) returns on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to own funds for SDDTs (PRA116) and own funds (PRA001) returns, as a warning.

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: OF07.00.01.01, c: 0220} = {t: OF07.00.01.01, c: 0230} + {t: OF07.00.01.01, c: 0235}
