Solvency capital requirement - non-life and health catastrophe risk: values must agree (IR.27.01, Bank of England rule IR_bv0639)

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

The rule in plain words

The item "Catastrophe Risk Charge Factor before risk mitigation" reported in Solvency Capital Requirement - Non-life and Health catastrophe risk (IR.27.01.01.03) should be equal to the ratio between "Specified Gross Loss" and "Exposure"

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.
