Non-life projection of future cash flows: a total must equal the sum of its parts (IR.18.01, Bank of England rule IR_bv1915)

A warning on the non-life projection of future cash flows template (IR.18.01), in the annual solo (ARS) and annual third-country branch (ARB) returns.

The rule in plain words

In template IR.18.01.01.01, ('Premium provision: Recoverable from reinsurance (after the adjustment)' (c0045) plus 'Claim provision: Recoverable from reinsurance (after the adjustment)' (c0085) ) should equal 'Total recoverable from reinsurance (after the adjustment)' (c0090) )

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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.18.01 as reported.
  6. 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

The Bank of England's formula. Cells are written as {t: table, r: row, c: column}.

{t: IR.18.01.01.01, c: C0090, z: Z0001} = sum({t: IR.18.01.01.01, c: C0045; C0085, 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.
