Own funds requirements for SDDTs (CA2 SDDT): other risk exposure amounts (TOTAL) should exceed or be equal to the sum of the "of which" rows (SC02.00.01.01, Bank of England check boe_b0139_ss)

A warning on the own funds requirements for SDDTs (CA2 SDDT) template (SC02.00.01.01), in the own funds for SDDTs (PRA116) return.

Line4 Check runs it on the own funds for SDDTs (PRA116) return, proven on test files, check by check: the same outcome on all three test files of that return.

The rule in plain words

OTHER RISK EXPOSURE AMOUNTS (TOTAL) should exceed or be equal to the sum of the "of which" rows

In column "All approaches" (0010) of Own funds requirements for SDDTs (CA2 SDDT) (SC02.00.01.01): "Other risk exposure amounts" (row 0690) must not be less than the sum of "Of which: Additional stricter prudential requirements based on Article 458" (row 0710), "Of which: Additional stricter prudential requirements based on Article 459" (row 0750) and "Of which: Additional risk exposure amount due to Article 3 CRR" (row 0760).

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is smaller than it may be, one of them is wrong: check both before you change either.
  3. 03The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark SC02.00.01 as reported.
  5. 05This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
