Viewing Loss Analysis Results

To view loss analysis results:

1.     In Portfolio Mode, access the results grid for your project. In Underwriting Contract Mode, open the contract for which you want to view detailed loss analysis results.

2.     In Portfolio Mode, make sure that the activity status is "Completed" and then select the analysis for which you want to view the results. Click the hyperlinked analysis name or highlight the row and then right-click the analysis and click (Open) on the shortcut menu.

In the Underwriting Contract Mode navigation pane, click Detailed Loss to view the most recent detailed loss analysis results. Alternatively, to view older detailed loss analysis results in Underwriting Contract Mode, click the triangle next to Detailed Loss Analysis and then select the desired results set.

       The loss results page for a catastrophe peril analysis displays various tables, such as the Summary EP (exceedance probability) Table, Annual EP Chart, and Event Loss Summary Table.

       If you ran the loss analysis with selected zones, the Summary EP Table Zone table appears in place of the Summary EP Table (which you can still open from the View Options panel). You can select the zonal results to include in the view. Example

       If you ran a portfolio or contract-level loss analysis where you saved the loss results by layer or where you ran it with reinsurance, and you selected the EP by Peril and EP by Model options in the Additional Details area, you can view the EP summaries by model and peril. The Summary EP Table will include By Peril and By Model columns.

       If you open a modified detailed loss analysis, the Summary EP table includes the AIR/Mod column, where the AIR icon identifies AIR results and identifies the modified results. The Event Loss Summary table also includes columns for the AIR results and the modified results. By default, the Loss Results tab for a non-catastrophe peril analysis displays the Contributing Contracts, 5 Year PSOLD Results, and 20 Year PSOLD Results tabs. If the analysis includes an XPR treaty, the Reinsurance Programs window appears by default. PSOLD Results tiles include the following PSOLD information:

       Limited Severity: The expected loss severity when limited to the layer in question as calculated using the PSOLD data. The severity applies to all the exposure covered by the layer in question.

       PSOLD Excess Claim Count: The average number of claims (based on the PSOLD data) expected to hit the layer in question. If the value was, for example, 0.5, you could expect one claim every two years.

       Layer Average Severity: The calculated Non Cat expected loss to the layer divided by the PSOLD Excess Claim count.

3.     For catastrophe peril analysis results, to view the Summary EP chart, Annual EP table, or Map, click Show/Hide Contents Item in the sidebar and then select those options.

When you select the Map option, a map appears. Map Tools enable you to analyze the results visually.

For non-catastrophe peril analysis results, to view the Contributing Contract Layers, Contribution Locations, and Reinsurance Program, click Show/Hide Contents Item in the sidebar and then select those options.

4.     To view the loss results in different ways, click the options.

Currently selected options are highlighted; to clear a selected option, click it. After you select an option, the system updates the tables and charts. The available options depend on your analysis settings.

a.     In the Perspective group, select the financial perspectives for which you want to view the loss results.

 
The “No result data generated for perspective: PreLayer Gross” message appears even when there may be Pre-Layer Gross results. This is because Touchstone does not currently display the Pre-Layer Gross losses in the Loss Results pane. However, you can use AIR ExportExpress to export the loss results to a CSV file and then view pre-layer gross losses (if there are any); to view the pre-layer gross losses in the report, you must select "Event Loss by Layer" as one of the reports to generate and "Pre-Layer Gross” as one of the perspectives. The pre-layer gross losses are in the column labeled "PreLayerGrossLoss". You can also run an SQL query to view the results in the PreLayerGrossLoss column in the dbo.t2_LOSS_ByLayer table (contact your database administrator for help with SQL queries).

b.     In the AIR/Mod group, which appears if you are viewing modified results, select any combination of AIR results, modified results, or the difference between the results.

c.     In the Agg/Occ group, select Aggregate (total losses in a year) or Occurrence (highest possible loss per year from a single event), or leave both options selected.

d.     In the EP Type group, select the type of EP that you want to view—Standard EP, Secondary EP, EP Value/Return Periods, or Tail Value at Risk. To edit the points for the Return Periods, click , enter the point values you want to use, and then click OK.

e.     In the Zones area, select the exposed areas for which you want to view results; this enables you to view more granular loss results than available when you leave the default setting, "All Exposed Areas". Example You can further refine the results by selecting one or more perils in the Zones area. Example The results change as you select zones and perils.

f.       In the Uncertainty Bands group, which becomes available for editing only when you select the Annual EP Chart, select Event Uncertainty in the list, specify the range of uncertainty by entering or selecting percent numbers in the P1 and P2 fields (where P1 is the first point in the range and P2 is the last point in the range), and then clicking Update. Uncertainty bands appear on the chart.

 

A catastrophe model must account for uncertainty in the damage. For a simulated event, the damage is uncertain and this uncertainty must be explicitly considered when calculating the insurer’s loss. For a given location and event, there is a probability associated with each damage ratio. There is a probability of no (0%) damage, a probability of complete (100%) damage and a probability of any amount of damage between 0 and 100.

g.     In the Transpose ribbon segment, select Transpose to transpose the axes of the Summary EP table.

h.     In the Peril and Model group, select Peril, Model, or both to include by Peril and/or by Model columns in the Summary EP table. If you select both Peril and Model, the EP Summary table breaks down first by peril, then by model.

 

       To view results by peril, your data must include peril information.

       You cannot view Loss Comparative Analysis or Marginal Impact results by peril or model, even if the results sets used in the analysis include this information.

i.        In the Events Detail group, which becomes available only when you select the Annual EP Chart, you can filter the loss results on historical and world scenarios events.

The Annual EP Chart initially displays the stochastic output of the loss analysis. When you select Historical or Scenarios, you overlay those events on the output.

j.        In the Chart Area group, you can specify the number of markers to display on the Annual EP Chart, display the chart legend and change the color palette used in the chart, clear the zoom, and switch axes. Moving the pointer over a marker displays information about the event. To zoom in on an area in the chart, click the pointer in the chart area and drag it to draw a box; to zoom out, click the Clear zoom icon. To change the color palette, make Legend active, click the colored circle in the Legend box, click the down arrow under "Hide", and select the color palette.
