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_bv0660)

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 "Total" value of the item "Ratio of eligible own funds to MCR" reported in Own funds (IR.23.01.01.01) should be equal to the ratio between the "Total eligible own funds to meet the MCR" and the "MCR"

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.
