Own funds and impact of long term guarantees measures and transitionals: values must agree (IR.23.01, IR.22.01, Bank of England rule IR_bv2018)

A blocking check on the own funds (IR.23.01) and impact of long term guarantees measures and transitionals (IR.22.01) templates, in the quarterly solo (QRS) and annual solo (ARS) returns.

The rule in plain words

The item "Total" value of the "Total basic own funds after deductions" reported in Own funds (IR.23.01.01.01) should be equal to the sum of the items reported above

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.

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark IR.23.01 as reported.
