Non-life claim development: a conditional check (IR.19.01, Bank of England rule IR_bv3030_04)

A blocking check on the non-life claim development template (IR.19.01), in the annual solo (ARS) and annual third-country branch (ARB) returns.

The rule in plain words

For the Gross discounted Best Estimate Provision for claims outstanding (IR.19.01.01.04), when the 'Line of Business' (Z0010) reported is "Total all lines of business", the 'Currency' (Z0030) reported must be "Total/NA"

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. 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. 03It runs only when your filing indicators mark IR.19.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
