The rule in plain words
The item "Diversification between sub-modules" reported in Solvency Capital Requirement - Non-life and Health catastrophe risk (IR.27.01.01.01) should be equal to the difference between "Health catastrophe risk" and the sum of all risks reported
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.
