Non-life technical provisions: a total must equal the sum of its parts (IR.17.01, Bank of England rule IR_bv1892)

The rule in plain words

With reference to the premium provisions, the item "Total recoverables from reinsurance/SPV and Finite Re before the adjustment for expected losses due to counterparty default" reported in Non-Life Technical Provisions (IR.17.01.01.01) should be equal to the sum of "Recoverables from reinsurance (except SPV and Finite Reinsurance) before adjustment for expected losses", "Recoverables from SPV before adjustment for expected losses" and "Recoverables from Finite Reinsurance before adjustment for expected losses"

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 table below and find the cells the rule reads.
  2. 02Add up the parts in your return and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark IR.17.01 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
