The rule in plain words
This sum represents Total Market Risk RWAs under all approaches
In column "All approaches" (0010) of Own funds requirements (CA2) (OF02.00.01.01): "Total risk exposure amount for position, foreign exchange and commodities risks" (row 0520) must equal the sum of "Risk exposure amount for position, foreign exchange and commodities risks under simplified standardised approaches (SSA)" (row 0530), "Risk exposure amount for position, foreign exchange and commodities risks under advanced standardised approaches (ASA) - for ASA desks only" (row 0571) and "Risk exposure amount for position, foreign exchange and commodities risks under internal model approach (IMA) - for IMA desks only" (row 0580).
What to do if your return fails it
- 01Open the tables 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- 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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.

{t: OF02.00.01.01, r: 0520, c: 0010} = sum({t: OF02.00.01.01, r: 0530; 0571; 0580, c: 0010})Other rules on Own funds requirements (CA2) (OF02.00.01.01)
- 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
- Total CVA Risk Exposure Amount under standardised approaches is the sum of CVA risk exposure amounts calculated using each CVA risk approach (boe_b1076)
- Total CVA Risk Exposure Amount under all approaches is the sum of CVA risk exposure amounts calculated using each CVA risk approach (boe_b1075)
- Own funds requirements (CA2): these items must be completed if the output floor is reported (boe_b0957)Blocking
- Total credit risk RWAs under standardised approaches should reflect the sum of SA on the SA, and IRB exposures on the SA (boe_b0793)Blocking
- Own funds requirements (CA2): a conditional check (boe_b0792)Blocking
- This is the Own Funds amount calculated by using as variable parameters c0010 or alternatively c0030 if c0030 is greater than c0010 (boe_b0791)Blocking
