Known Issue 375

Incorrect gross losses are produced when exposures with multi-peril terms and sub-limits have disaggregation applied.

Issue ID	375
Summary	Incorrect gross losses are produced when exposures with multi-peril terms and sub-limits have disaggregation applied.
Description	Incorrect gross losses are produced when exposures with multi-peril terms and sub-limits have disaggregation applied. The issue causes substantially higher than expected gross losses since the peril-specific sub-limit terms do not apply on said perils’ losses in these cases. The issue is restricted to those situations where sub-limits are present. These issues are not present when running the analysis one peril at a time nor do we see this with row-wise exposure coding. Disaggregation can be triggered even without user-choice in some regions, please refer the Exposure Disaggregation document on the Client Portal for more details.
