Check your file for this ruleWhat to do if it fails

The rule in plain words

SDDTs aren’t subject to CRDIV buffers so these rows should be the same (Total capital)

In column "Amount" (0010) of Capital adequacy - capital ratios and capital levels for SDDTs (CA3 SDDT) (SC03.00.01.01): "Overall capital requirement ratio (OCR)" (row 0160) must equal "Total capital requirement (TCR) ratio" (row 0130).

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02The two values must be the same. Find which of the two is right, and correct the other one.
  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 SC03.00.01 as reported.
  5. 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The cells it reads

Capital adequacy - capital ratios and capital levels for SDDTs (CA3 SDDT) (SC03.00.01.01)

Rows

  • R0130Total capital requirement (TCR) ratio
  • R0160Overall capital requirement ratio (OCR)

Column

  • C0010Amount

A worked example

With simple numbers.

Illustrative values
Total capital requirement (TCR) ratio1,200
What the rule then expects

Overall capital requirement ratio (OCR) must then be 1,200.

1,200Passes
1,300Fails

A file that reports 1,200 passes. One that reports 1,300 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.
