Touchstone 2023 (11.5) includes enhancements to Verisk models and the user interface, data updates, and more.

This release provides parity with previous versions of Touchstone.
Note: This release does not support dynamic hazard/LLEI for previous model versions.

Model enhancements

Model updates include the following items:
  • Verisk Earthquake Model for the Middle East (new)
  • Verisk Inland Flood Model for Italy (new)
  • Updates for the Verisk U.S. Hurricane Model for Offshore Assets
  • Information about previous model version (PMV) support
  • Information about updates to model version numbers
  • Verisk Severe Thunderstorm Model for the United States
    Important: Peril codes are different in Geospatial analysis than they are in Detailed Loss analysis. We do not support the new sub-peril set code for the Verisk Severe Thunderstorm Model for the United States, which is 11534336. Instead, we are still using the old sub-peril code, which is 2. This mismatch creates an issue when a user tries to join detailed loss results with geospatial analysis accumulation output.

Data updates

  • Annual Industry Exposure Databases updates for offshore assets within the Gulf of Mexico
  • Basemaps and map library updates from ESRI to ThinkGEO map libraries
  • New geospatial layers (26)
  • Location-level event intensity (LLEI) updates to work with the Verisk Earthquake Model for the Middle East and the Verisk Inland Flood Model for Italy

Software enhancements

  • Financial engine support: New business logic, including to geospatial analysis; logging enhancements; Specialty Business Solutions (SBS) data transfer; EDM data converter (EDC) updates.
    Note: The geospatial module is not completely at parity with the loss engine. We currently provide parity for the minimum/maximum deductible algorithms for location, layer, and sublimit, and for percent loss of coverage deductible on location. We also support a third tier for sublimits. However, in some cases the results in the backend table, txx_EC_ByLayer, for exposed ground up resullts are not intuitive. We will address this discrepancy when we migrate the entire geospatial module to the new financial engine.
  • CLF export.
  • Extended support for Middle East and Italy CLF/CLA.
  • Zone sets: Added ability to import and export zone sets from one (Touchstone or (Touchstone Re installation to another, from one release to another, and from one business unit to another.
  • Min-max deductible for site deductible placed on a location.
  • Integration of demand surge tool into Touchstone.

API updates

New APIs and enhancements to existing APIs to support Verisk models and the Touchstone application.
