Non-life outwards reinsurance contract information and non-life outwards reinsurance contract reinsurer exposures: a conditional check (IR.30.03, IR.30.04, Bank of England rule IR_bv2619)

A blocking check on the non-life outwards reinsurance contract information (IR.30.03) and non-life outwards reinsurance contract reinsurer exposures (IR.30.04) templates, in the annual solo (ARS) and annual third-country branch (ARB) returns.

The rule in plain words

If C0240 is -1, then C0180 must also be -1. Additionally, IR.30.04 C0100 multiplied by IR.30.03 C0240 should only be calculated when C0240 is not -1

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. 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. 03The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark IR.30.03 and IR.30.04 as reported.
  5. 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

if {t: IR.30.03.01.01, c: C0240, z: Z0001} = -1 then {t: IR.30.04.01.01, c: C0180, z: Z0001} = -1 else {t: IR.30.04.01.01, c: C0180, z: Z0001} = {t: IR.30.04.01.01, c: C0100, z: Z0001} * {t: IR.30.03.01.01, c: C0240, z: Z0001}

Checks like this one, run at the point of submission, are the first step to real-time supervision. Line4 builds SupTech software for financial regulators that runs checks like these as each return arrives.
