Check your file for this ruleWhat to do if it fails

The rule in plain words

The item "Total Flood EEA Regions before diversifications" reported in Solvency Capital Requirement - Non-life and Health catastrophe risk (IRR.27.01) [RFF/MP/RM] should be equal to the sum of the regions reported above

The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  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 IRR.01.01 and IRR.27.01 as reported.
  5. 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
