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.
Configuring detailed loss analyses
These are the basic tasks for configuring detailed loss analyses.
Specify output options
Set output options to define the information to include in loss analysis results.
Configure a zonal loss analysis
Users with appropriate permissions can create and manage zone sets for use with detailed loss analyses. They create zone sets through the Zone Set Manager, which requires a license, in the Administration Console.

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.

    - Set detailed loss analysis settings
      In Analysis Settings , configure model, region, event sets, perils, demand surge, financial, and flexibility settings.
    - Selecting Perils
    - Apply an event set filter
      Applying an event set filter enables you to run a standard loss analysis for a user-defined subset of events in the event set that you have selected.
    - Specify demand surge options
      Reflect the increased cost of labor and materials following a major catastrophe by setting the Demand Surge options for loss results.
    - About configuring financial settings
      Configure a detailed loss analysis to use various financial settings.
    - About flexibility settings
      You can perform sensitivity analyses by applying a loss modification factor or factors to detailed loss analyses.
    - Apply reinsurance programs
      Configure detailed loss analyses to apply treaty terms in associated reinsurance programs to the loss analyses results.
    - Specify output options
      Set output options to define the information to include in loss analysis results.
      - Select loss perspectives
        Use Output Options to select loss perspectives to include in loss results. Each loss perspective provides you with a different way of measuring losses from a particular event.
      - Select the Save Losses By resolution
        In the Output Options pane, select the resolution, that is, the level of event detail, by which to save loss results.
      - Configuring a CLA for transfer of analysis results
        Company Loss Association (CLA) allows you to perform change management using all financial perspectives.
      - Summary (AAL) information
        In the Output Options pane, select a Summary (AAL Only) option if you want to include, in the loss results, AAL (average annual losses) by contract summary only or by both contract and location summary.

- 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.

Configure a zonal loss analysis

Users with appropriate permissions can create and manage zone sets for use with detailed loss analyses. They create zone sets through the Zone Set Manager, which requires a license, in the Administration Console.

Procedure

In the New Detailed Loss Analysis pane, select Output.
In the Output Options pane, in the Zone Output area, select the Zone check box.
The application displays fields that enable you to configure settings and select zone sets.
[Optional] Select Zones by Peril to include the zones by peril in the analysis results.
To view the zones by peril in the analysis results, select a zone in the Zones area on the ribbon, select one or more zones, and then select one or more perils. The Summary EP Table Zone table reflects your selections.
[Optional] Select Retain Annual EP Table By Zone to persist the Annual EP table by zone in the database.
The Edit icon appears only after you select Retain Annual EP Table By Zone. Selecting this option increases the table size significantly.
In the Available Zone Sets panel, select each zone set to include in the loss analysis and then click >>> (right-pointing brackets) to move the selected zone sets to the Selected Zone Sets panel.
Useful information about zone sets:
- Use the Search box to filter the list of available zone sets, for example, by typing n to include only zone sets that start with n.
- The maximum number of viewable zones in a zone set is 50. If there are more than 50 zones, a message will indicate that there are xxx more regions.
- Touchstone supports up to 50,000 zones in a detailed loss analysis and displays a warning message: If your selection exceeds 50,000 zones, the zone set that exceeds the limit will not be included in the analysis.
- Expand each zone set if you want to view the zones in the set.
- If you have the appropriate permissions, you can edit zones by clicking (Open Zone Set Manager).
- To remove selected zone sets, select them and then click <<< (left-pointing brackets).
