Off-balance sheet items - general and outwards reinsurance balance sheet exposures: a value must not be less than another (IR.03.01, IR.31.01, Bank of England rule IR_bv0782_02)

A blocking check on the off-balance sheet items - general (IR.03.01) and outwards reinsurance balance sheet exposures (IR.31.01) templates, in the annual solo (ARS) return.

The rule in plain words

Sum of ‘Assets pledged by reinsurers in template Off-Balance sheet items (IR.03.01) - general’ should be equal or higher to sum of ‘Assets pledged by reinsurers’ reported in IR.31.01 - Share of reinsurers [including Finite Reinsurance and SPV's]

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. 02Compare the values in your return. If the first is smaller than it may be, one of them is wrong: check both before you change either.
  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.03.01 and IR.31.01 as reported.
  5. 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
