Reinsurer and collateral provider entity information and life outwards non-proportional reinsurance: a conditional check (IR.30.05, IR.30.08, Bank of England rule IR_bv0059_06)

A blocking check on the reinsurer and collateral provider entity information (IR.30.05) and life outwards non-proportional reinsurance (IR.30.08) templates, in the annual solo (ARS) return.

The rule in plain words

If a unique value for "Reinsurer LEI" (C0030) is reported in IR.30.08.01 then this unique value must also be present in "Code of the Reinsurer Entity or Collateral Provider, preceded by type of code" (C0010) for columns C0030, C0040, C0050, C0070, and C0080 reported in template IR.30.05.01

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. 03It runs only when your filing indicators mark IR.30.05 and IR.30.08 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
