The rule in plain words
The item "Diversification effect between regions" reported in Solvency Capital Requirement - Non-life and Health catastrophe risk (IR.27.01.01.03) should be equal to the difference between "Total Earthquake after diversification" and "Total Earthquake all Regions before diversification"
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.
