Modeled loss uncertainty

Standing commercial catastrophe-model product for buyer-supplied policies, portfolios, exposure locations, and attack scenarios. The U.S. component supports deterministic, probabilistic, and geospatial terrorism analysis; conventional-bomb, CBRN, and aircraft-crash scenarios; policy- and portfolio-level loss estimation; nationwide 1 km latitude/longitude modeling with finer ZIP resolution in 15 metropolitan areas; and a 500,000-year stochastic catalog. Model loss metrics and associated uncertainty are delivered through the Touchstone user interface and APIs. Touchstone is a delivery platform within this Source boundary, not a separate Source. Outputs are modeled risk and loss estimates, not current threat intelligence or a prediction that one premises will be attacked.
