Impact of long term guarantees measures and transitionals and minimum capital requirement - only life or only non-life activity: a conditional check (IR.22.01, IR.28.01, Bank of England rule IR_bv1771)

A blocking check on the impact of long term guarantees measures and transitionals (IR.22.01) and minimum capital requirement - only life or only non-life activity (IR.28.01) templates, in the annual solo (ARS) return.

The rule in plain words

The MCR reported in Minimum Capital Requirement (IR.28.01.01.05) - Only life or only non-life insurance or reinsurance activity should be equal or larger than 25% of the "SCR" and equal or less than 45% of the "SCR" when the "MCR" is different from the "Absolute floor of the MCR"

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 IR.28.01 as reported.
  5. 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
