Non-life income and expenditure and 2 other templates: values must agree (IR.05.04, IR.17.01, IR.02.01, Bank of England rule IR_bv1919)

A blocking check on the non-life income and expenditure (IR.05.04), non-life technical provisions (IR.17.01) and balance sheet (IR.02.01) templates, in the annual solo (ARS) and annual third-country branch (ARB) returns.

The rule in plain words

For each LoB and Total in Non-Life Technical Provisions (IR.17.01.01.01), "technical provisions" minus "recoverables from reinsurance" should be equal to "technical provisions (total)" minus "total recoverables from 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.

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark IR.17.01 as reported.
