Known Issue 161

Some portfolio DLF exports will be incorrectly labeled as not having demand surge included.

Issue ID	161
Summary	Some portfolio DLF exports will be incorrectly labeled as not having demand surge included.
Description	In Touchstone Rev13.3, users with Analyze Re Rollup enabled may encounter scenarios where results from an analysis with the new event set, World All Perils for 2026 US models, are run with demand surge as program-specific instead of with demand surge. In such a case, any DLF export of these results will be flagged as no demand surge applied. Subsequent analysis of this DLF in Verisk Synergy Studio will double-apply demand surge for Verisk Tropical Cyclone Model for the United States, Verisk Winter Storm Model for the United States, and Verisk Inland Flood Model for the United States.
Resolved in	Future Verisk Synergy Studio release
Date posted	07/09/2026
Software versions affected	13.3

Workaround	If DLF export for a portfolio analysis using the new event set is required, avoid using Analyze Re Rollup and make sure demand surge is set to with in the analysis configuration.
