A blocking check on the solvency capital requirement (IRR.25.04), basic information - general (IR.01.02) and impact of long term guarantees measures and transitionals (IR.22.01) templates, in the annual solo (ARS) return.

The rule in plain words

SCR = sum of notional SCRs (SF firms)

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 IR.01.02, IR.25.04 and IRR.25.04 as reported.
  5. 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
