Non-life outwards reinsurance contract information: values must agree (IR.30.03, Bank of England rule IR_bv0107)

A blocking check on the non-life outwards reinsurance contract information template (IR.30.03), in the annual solo (ARS) and annual third-country branch (ARB) returns.

The rule in plain words

Gross estimated reinsurance premium ceded" (C0450) should equal "Gross Estimated Reinsurance Contract Premium" (C0160) multiplied by "% of whole contract ceded to reinsurers" (C0440)

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.30.03 as reported.
