The rule in plain words
Total CVA Risk Exposure Amount under all approaches is the sum of CVA risk exposure amounts calculated using each CVA risk approach
In Own funds requirements (CA2) (OF02.00.01.01): "Total risk exposure amount for credit valuation adjustment" in column "All approaches" (row 0640, column 0010) must equal the sum of "Standardised Approach (SA-CVA)" in column "All approaches" (row 0641, column 0010), "Basic Approach (BA-CVA)" in column "Standardised approaches only (Output Floor)" (row 0642, column 0020) and "Alternative Approach (AA-CVA)" in column "All approaches" (row 0643, column 0010).
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- 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 OF02.00.01 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
Own funds requirements (CA2) (OF02.00.01.01)
Rows
- R0640Total risk exposure amount for credit valuation adjustment
- R0641Standardised Approach (SA-CVA)
- R0642Basic Approach (BA-CVA)
- R0643Alternative Approach (AA-CVA)
Columns
- C0010All approaches
- C0020Standardised approaches only (Output Floor)
A worked example
With simple numbers.
Total risk exposure amount for credit valuation adjustment, All approaches must then be 2,450.
A file that reports 2,450 passes. One that reports 2,550 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 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.

{t: OF02.00.01.01, r: 0640, c: 0010} = {t: OF02.00.01.01, r: 0641, c: 0010} + {t: OF02.00.01.01, r: 0642, c: 0020} + {t: OF02.00.01.01, r: 0643, c: 0010}Other rules on Own funds requirements (CA2) (OF02.00.01.01)
- Total CVA Risk Exposure Amount under standardised approaches is the sum of CVA risk exposure amounts calculated using each CVA risk approach (boe_b1076)

- Own funds requirements (CA2): this sum represents the calculation for Total Risk exposure amount under all approaches (boe_b1092)
- Own funds requirements (CA2): this sum is to derive Total Credit Risk RWAs under all approaches (boe_b1093)Blocking
- Own funds requirements (CA2): these items must be completed if the output floor is reported (boe_b0957)Blocking
