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
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.

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 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.
  - Configuring detailed loss analyses
    These are the basic tasks for configuring detailed loss analyses.
  - Working with loss analysis results
    - View loss analysis results
      This procedure describes how to view loss analysis results.
    - Loss Results Maps
    - 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.
    - Annual EP chart
    - Event Loss Summary Table
      This table displays more detailed information about each event generated by the standard (probabilistic) loss analysis.
    - Modeled Exposure Summary 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).
- User model management
  Use User Model Management to build custom non-Verisk models and seamlessly integrate them into Touchstone.
- Event set management
  Your Touchstone Re installation includes event set files for each peril and region licensed by your company.
- Configuring a loss analysis with a custom model
- Analysis Settings pane (Loss)
  Use this pane to configure catastrophe analysis settings.
Reinsurance
The Reinsurance Program Manager enables you to create, import, and manage reinsurance programs.
Touchstone data export types
Touchstone enables you to export different types of data.
Activity Monitor
The Activity Monitor displays the status of all activities.
Managing data sources
Use Data Source Management to manage Touchstone databases.
User model management
Use User Model Management to build custom non-Verisk models and seamlessly integrate them into Touchstone.

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.

The results grid now includes a Product Version column.

The following table summarizes post-processing capabilities for the available analyses.

Note:

Loss Comparative Analytics has been retired in Touchstone 11.0 and later.


Catalog Type	Updated?	Marginal Impact	Loss Group	Comparative	CATXOL
Stochastic	Yes	No	No	Yes	No
Stochastic	No	Yes	Yes	Yes	Yes
Historical or RDS	Yes	No	No	Yes	No
Historical or RDS	No	No	Yes	Yes	Yes

Note:

This feature does not apply to Data Quality Analysis, Hazard Analysis, or Geospatial analyses.

Viewing loss analysis results from previous product versions

When working with results from previous product versions, consider the following usage notes:

You can view all tables, charts, and results from previous analyses.
While you can view results for Marginal Impact and Loss Groups analyses, you cannot run Marginal Impact or Loss Group analyses on old event sets.
If older model files have changed, event tables may not be able to display event descriptions. If the description and/or event IDs have not changed, Touchstone will display the information.
If older model files exist, the map displays the storm tracks and other details.
Analysis settings and logs display the product (system), model, and catalog versions that were used in the analysis.
You can group old losses only; you cannot group new and old losses together.

Exporting loss analysis results from previous product versions

You can export loss analysis results from previous product and model versions to a CSV file and to a CLF file. Click the links for each export type for specific considerations when exporting results from previous product and/or model version.
