Non-life technical provisions and minimum capital requirement - both life and non-life activity: a value must not be more than another (IR.17.01, IR.28.02, Bank of England rule IR_bv1801)

A blocking check on the non-life technical provisions (IR.17.01) and minimum capital requirement - both life and non-life activity (IR.28.02) templates, in the annual solo (ARS) return.

The rule in plain words

The Item "Net (of reinsurance/SPV) best estimate and TP calculated as a whole" reported in template Minimum Capital Requirement (IR.28.02) - Both life and non-life insurance activity should be higher than the amount reported in template Non-Life Technical Provisions (IR.17.01) for General liability insurance and proportional reinsurance

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. 02Compare the values in your return. If the first is bigger than it may be, one of them is wrong: check both before you change either.
  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.17.01 and IR.28.02 as reported.
  5. 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
