About loss analyses
Touchstone enables you to model catastrophic (CAT) events to estimate property and workers' compensation losses.
Marginal impact analysis
A marginal impact analysis enables you to view the effect that a specific loss results set (the target or new portfolio/contract) has on another loss results set (the reference portfolio).

Using Touchstone online Help
You can access the top-level or context-sensitive Touchstone online help from within the application or from the Client Portal. You can then search for content, bookmark pages, and generate output to other formats.
Import data from external sources
You can import exposure data, map layers, projects, and reinsurance packages from external sources into Touchstone databases.
Projects and exposure views
Projects are a useful way to organize your data. They contain exposure views that contain the data that you want to focus on.
Geospatial analysis
Geospatial analysis enables you to perform a deterministic risk analysis with your own view of risk on accumulations of property exposures and workers' compensation information in given areas exposed to natural and man-made catastrophes.
Exposure data validation
Verisk provides a reference containing information about Touchstone exposure data.
Data Quality analysis
The most effective way to assess and enhance portfolio-level or contract-level catastrophe exposure data is to use Touchstone's Data Quality diagnostics. These diagnostics enable you to determine the strengths and weaknesses of the exposure data you are using for analyses and supplement that data when it is missing or weak.
Hazard analysis
Hazard analysis enable you to identify the relevant catastrophe hazards for locations in your exposure data.
About loss analyses
Touchstone enables you to model catastrophic (CAT) events to estimate property and workers' compensation losses.
- About the detailed loss analysis module
  Use the detailed loss analysis module to run a detailed loss analysis on the same exposure data that you imported for catastrophe modeling.
- Loss Group analysis
  A Loss Group analysis enables you to combine two or more sets of loss results from different analyses into a single loss view, or group, which is then available for use as input to subsequent processes or analyses.
- CAT XOL analysis
  A catastrophe excess of loss reinsurance program (CAT XOL) indemnifies the ceding company for that portion of the loss that exceeds the limit of its own retention per event.
- Marginal impact analysis
  A marginal impact analysis enables you to view the effect that a specific loss results set (the target or new portfolio/contract) has on another loss results set (the reference portfolio).
  - Configuring and running a marginal impact analysis
    A marginal impact analysis enables you to view the effect that a specific loss results set (the target, or new portfolio) has on another loss results set (the reference, or base, portfolio).
  - Working with marginal impact analysis results
    The Marginal Impact Analysis results grid displays a table for each relevant Admin Boundary-peril set that you selected.
