Outwards reinsurance balance sheet exposures: this value must not be reported as a positive value (IR.31.01, Bank of England rule IR_bv2517)

A blocking check on the outwards reinsurance balance sheet exposures template (IR.31.01), in the annual group (ARG) return.

The rule in plain words

This value must not be reported as a positive value

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is bigger than it may be, one of them is wrong: check both before you change either.
  3. 03It runs only when your filing indicators mark IR.31.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
