Non-life income and expenditure: a value must not be less than another (IR.05.04, Bank of England rule IR_bv0101)

A warning on the non-life income and expenditure template (IR.05.04), in the annual solo (ARS) and annual third-country branch (ARB) returns.

Check your file for this ruleWhat to do if it fails

The rule in plain words

Net earned premiums (R0220) should typically be greater than or equal to Net earned premiums from business transfers-in (R0410)

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 table below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is smaller than it may be, one of them is wrong: check both before you change either.
  3. 03It runs only when your filing indicators mark IR.05.04 as reported.
  4. 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
