Configuring and Running a Marginal Impact Analysis in Underwriting Contract Mode

Before You Begin

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 portfolio). You can run a Marginal Impact Analysis in Portfolio Mode or in Underwriting Contract Mode.

In Underwriting Contract Mode, you choose a contract, and Touchstone performs a Marginal Impact Analysis that compares the most recent set of Detailed Loss Analysis results for this contract (the target or new portfolio) against the reference portfolio that you choose.

Note:

When running a Marginal Impact Analysis in Underwriting Contract Mode, Touchstone uses the World All Perils region-peril set for the analysis.

Procedure

To configure and run a Marginal Impact Analysis in Underwriting Contract Mode:

  1. Add or open a contract
  2. Run a Detailed Loss Analysis.

    This set of results serves as the target (new) set of analysis results for this Marginal Impact Analysis. This set of results will appear as the "Analysis Target" in the Marginal Impact Analysis pane.

    Note:

    Touchstone uses the most recent Detailed Loss Analysis results for a contract as the target (new) analysist results set for a Marginal Impact Analysis.

  3. In the Contract Summary Dashboard, select Marginal Impact.
  4. Navigate to the Analysis Options > Marginal Impact Analysis pane. Then, under Marginal Impact Diagnostics, select Base Loss Result:
    1. Select or clear Exclude contracts based on Expiring Contract ID.

      Touchstone will remove losses for these contracts from the reference portfolio. You can add or modify existing contract names in the text box.

    2. Specify a Window value to generate averaged EP loss results.

      Defining a window is the user's choice. The default is "0", meaning that Marginal Impact will not average the losses.

    3. Select the reference analysis results with which you want to combine the target analysis results set that you selected in step 2.

      This set of reference analysis results will appear as the "Reference Portfolio" in the Marginal Impact Results table.

      Note:

      For underwriters to run Marginal Impact Analyses in Underwriting Contract Mode, a user with appropriate permissions must first run a Detailed Loss Analysis in Portfolio Mode on the master portfolio exposure view. The results of this analysis serve as the reference portfolio for the Marginal Impact Analyses that underwriters run in Underwriting Contract Mode. Users with appropriate permissions can run multiple Detailed Loss Analyses and/or Loss Group Analyses in Portfolio Mode on the master portfolio exposure view, thereby providing multiple reference portfolio choices for underwriters running Marginal Impact Analyses in Underwriting Contract Mode.

  5. Select the Configure Groups pane to associate perils with an Admin Boundary that is defined in Touchstone. Then, optionally, select a saved Admin Boundary template with its associated perils to use in this analysis, or specify a new combination.

    You can use a new selection for this analysis and save it as a template for later use.

  6. Select Analysis Management to configure analysis-specific functions.
  7. Click Run.

    Touchstone adds the analysis to the Activity Monitor queue for processing when the required system resources are available.

    Note:

    The analysis type in the Activity Monitor is "Impact Analysis," while it is "Marginal and portfolio impact analysis" in the results grid

  8. To view the analysis results, open the contract for which you want to view the most recent Marginal Impact results and then click Marginal Impact.
