Non-life technical provisions: values to report together, or not at all (IR.17.01, Bank of England rule IR_bv2152)

A blocking check on the non-life technical provisions template (IR.17.01), in the quarterly solo (QRS) return.

The rule in plain words

For each LoB and Total in Non-Life Technical Provisions (IR.17.01.02.01), if total best estimate - gross is reported then the corresponding risk margin should also be reported, and for each LoB and Total, if risk margin is reported then the corresponding total best estimate - gross should also be reported

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. 02Report these values together, or leave them all out.
  3. 03It runs only when your filing indicators mark IR.17.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
