Solvency capital requirement - non-life and health catastrophe risk: values must agree (IR.27.01, Bank of England rule IR_bv0686_01)

A blocking check on the solvency capital requirement - non-life and health catastrophe risk template (IR.27.01), in the annual solo (ARS) return.

Check your file for this rule

The rule in plain words

The item "Catastrophe Risk Charge after risk mitigation" reported in Solvency Capital Requirement - Non-life and Health catastrophe risk (IR.27.01.01.04) should be equal to "Catastrophe Risk Charge before risk mitigation" minus "Estimated Risk Mitigation" added by "Estimated Reinstatement Premiums"

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.27.01 as reported.
