| Summary |
A discrepancy in the calculation of treay losses can
be seen when running CAT XOL analyses resulting in a numbers
difference depending on the save by options selected. |
| Description |
A discrepancy has been observed in the calculation of treaty losses within the CATXOL engine, resulting in different loss numbers between the "SaveByLayer" and "SaveByUDF" output options. The difference in treaty loss calculations arises from how treaties are processed based on the output option used:
* SaveByLayer: All treaties are loaded into the engine without checking the Line of Business (LOB) of the exposure or the treaties.
* SaveByUDF: Only treaties that match the LOB criteria are loaded after performing a verification process.
As a result, the varying number of treaties processed impacts the calculated reinsurance loss numbers, affecting the overall PostcatNet Loss numbers. |

| Workaround |
Given that LOB filter is part of the treaty - the save by
UDF is the correct one. So a user should save by UDF to get Post CAT
net loss numbers for LOBs. |
