Non-life claim development: a total must equal the sum of its parts (IR.19.01, Bank of England rule IR_bv1909_04)

The rule in plain words

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. 02Add up the parts in your return and compare the result with the total.
3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
4. 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
5. 05It runs only when your filing indicators mark IR.19.01 as reported.
6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
