Check your file for this ruleWhat to do if it fails

The rule in plain words

In each of "Average daily value" (column 010), "Peak daily value" (column 020), "Average daily value" (column 030) and "Peak daily value" (column 040) of Part 2: Collateral required for derivative transactions entered into as part of risk management (article 6(3)(b)) (SR808.02.08.02): "TOTAL" (row 150) must equal the sum of 9 rows (listed below).

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Add up the parts in your return and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark SR808.02.08 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
