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.
Working with loss analysis results
Summary EP table
For catastrophe peril analyses, the Summary EP Table (exceedance probability) displays expected losses, average annual losses (AAL [EV], standard deviation (SD), tail value at risk (TVAR), and losses for specific points on the probability curve.
Summary EP table - by peril and model
Use the Summary EP Table (exceedance probability) to view results by peril, sub-peril, or model if you configure your analysis to include these output options.

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.

    - Summary EP table
      For catastrophe peril analyses, the Summary EP Table (exceedance probability) displays expected losses, average annual losses (AAL [EV], standard deviation (SD), tail value at risk (TVAR), and losses for specific points on the probability curve.
      - Summary EP table - by return period
        Use the Summary EP Table (exceedance probability) to view the return period and its definition for each loss exceedance percentage.
      - Summary EP table - by perspective
        Use the Summary EP Table (exceedance probability) to view results by any of the perspectives that were configured in the loss analysis and returned losses.
      - Summary EP table - by peril and model
        Use the Summary EP Table (exceedance probability) to view results by peril, sub-peril, or model if you configure your analysis to include these output options.
      - Edit Summary EP Points dialog box
        The Edit Summary EP Points dialog box allows you to edit or add exceedance probability points to the Summary EP Table.

    - Use modeled losses from previous product versions
      You can view and export detailed loss analysis results from previous product versions of the product even if the models have been updated.
  - Reference: Detailed loss analysis
- 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).

Summary EP table - by peril and model

Use the Summary EP Table (exceedance probability) to view results by peril, sub-peril, or model if you configure your analysis to include these output options.

Peril and model

See Select additional details for the output for more information.

To view EP summary results, select either or both of the Peril and Model buttons in the Peril and Model segment of the ribbon. (By default these buttons are not selected.) The Summary EP table displays results first by peril, then by model. If you saved the results by peril and sub-peril, you can select the Subperil button to view the results broken out into single sub-perils.

Note: Marginal Impact results are not viewable by peril or model, even if the results sets used in the loss analysis include this information.
