Solvency capital requirement - simplifications: values must agree (IRR.26.07, Bank of England rule IR_bv0774_04_03)

A blocking check on the solvency capital requirement - simplifications template (IRR.26.07), in the annual solo (ARS) return.

Check your file for this rule

The rule in plain words

The item "Ring Fenced Fund/Matching adjustment portfolio or remaining part" should be reported in Solvency Capital Requirement - Simplifications (IRR.26.07) [RFF/MP/RM]

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 IRR.26.07 as reported.
