The rule in plain words
RISK WEIGHTED EXPOSURE AMOUNT for Credit risk is the sum of SA Credit Risk, Securitisation Positions and row 0460
In column "All approaches" (0010) of Own funds requirements for SDDTs (CA2 SDDT) (SC02.00.01.01): "Risk weighted exposure amounts for credit, counterparty credit and dilution risks and free deliveries" (row 0040) must equal the sum of "Standardised Approach (SA)" (row 0050), "Risk exposure amount for contributions to the default fund of a CCP" (row 0460) and "Securitisation positions" (row 0470).
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- 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 SC02.00.01 as reported.
- 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
