Own funds requirements (CA2): a total must equal the sum of its parts (CP02.00.04.01, Bank of England check boe_b0753)

A blocking check on the own funds requirements (CA2) template (CP02.00.04.01), in the capital+ actuals and forecasts (PRA112) return.

Line4 Check runs it on the capital+ actuals and forecasts (PRA112) return, proven on test files, check by check: the same outcome on all eight test files of that return.

The rule in plain words

In each of 5 columns (listed below) of Own funds requirements (CA2) (CP02.00.04.01): "Total risk exposure amount - output floor (WITH MULTIPLIER AND ADJUSTMENT)" (row 0031) must equal "Relevant Multiplier" (row 0032) multiplied by "Total risk exposure amount using standardised approaches (output floor - pre-multiplier)" (row 0033) plus "Output Floor Adjustment (OF-ADJ)" (row 0038).

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 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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 CP02.00.04 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
