Aggregate Model Builder
Aggregate Model Builder gives licensed users the flexibility to create their own custom models, and seamlessly integrate non-Verisk models into Touchstone Re.
This is not the same as Touchstone's Model Builder.
Aggregate models can be created for any country supported in Touchstone Re and some additional countries that are not traditionally modeled in Touchstone Re. These include Argentina, Bahrain, Brazil, Croatia, Iran, Jordan, Kazakhstan, Kuwait, Lebanon, Malaysia, Oman, Papua New Guinea, Qatar, Russian Federation, Saudi Arabia, South Africa, Thailand, Ukraine, United Arab Emirates, and Yemen.
Aggregate models can be created for the following perils: earthquake, flood, tropical cyclone, severe thunderstorm, winter storm, and wildfire/bushfire.
Custom models involve the use of user-created Damage Factor Files (DFFs). You can associate a model-specific damage factor file (DFF) to calculate losses for custom Sums Insured exposures. Touchstone Recalculates losses for custom models by multiplying event damage factors by custom sums insured to generate the ground-up losses. These are then applied to reinsurance treaty terms entered in Touchstone Re to produce contract losses. Custom models can be run in parallel to Verisk models.
In CATRADER this feature is known as Custom Models and is packaged under the Exposure Management Module (EMM) offering.
