The rule in plain words
The item "Catastrophe Risk Charge Credit & Suretyship after risk mitigation/Total before diversification" reported in Solvency Capital Requirement - Non-life and Health catastrophe risk (IR.27.01) should be equal to the sum of "Catastrophe Risk Charge Credit & Surety after risk mitigation - Large Credit Default/Total" and "Catastrophe Risk Charge Credit & Suretyship after risk mitigation - Recession Risk/Total" reported above
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.
What to do if your return fails it
- 01Open the tables below and find the cells the rule reads.
- 02Add up the parts in your return and compare the result with the total.
- 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
- 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
- 05It runs only when your filing indicators mark IR.27.01 as reported.
- 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

A worked example
With simple numbers.
Total before diversification, Catastrophe Risk Charge Credit & Suretyship after risk mitigation must then be 2,000.
A file that reports 2,000 passes. One that reports 2,100 fails, by 100.
The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.
Which returns it applies to
Line4 Check runs it on annual solo (ARS) return on Bank of England taxonomy 2.2.0. The Bank of England applies it to annual solo (ARS) returns, as a blocking check.
