Summary EP table


The Summary EP table displays catastrophe expected losses, non-catastrophe expected losses (NonCat EV), average annual losses (AAL[EV]), standard deviation (SD) and losses for specific points on the probability curve as designated by the administrative user. The table displays losses as annual aggregate losses—the total loss across events for each simulated year, or as annual occurrence lossesthe largest loss for each simulated year.

  If you ran a Loss Comparative Analysis, the analysis results tables and charts include the comparative results.


Depending on how the analysis was run, you can see the results for all perspectives that were configured in the analysis provided that they returned loss values. On the Loss Results ribbon, in the Perspective area, you select the perspectives that you want to appear in the Summary EP Table. Each perspective appears as a row; with a separate row for both aggregate (AGG) and occurrence (OCC) losses. When you select View By > Treaty, and then select the Ground Up or Gross perspectives, targets with Treaty losses are labeled "Treaty Ground Up" and "Treaty Gross".

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).

EP Type

For each loss analysis, you can view the results by EP type. By default, the system generates and displays a standard mean curve (Standard EP). During every analysis, secondary uncertainty is applied and you can view the EP with secondary uncertainty in the Summary EP table by selecting Secondary EP. This adds another header row to the table so that you see aggregate and occurrence losses (plus their respective perspectives) for that new row. The system also calculates Tail Value at Risk (TVAR) for every analysis and you can add that in order to see TVaR for both the Standard and Secondary EP curves. If you select all three EP types, you will see a table similar to this (with appropriate values filled in). If you applied a loss modification factor to the analysis, the table will include an AIR/Mod column. If you ran a non-catastrophe peril analysis, the table will include a NonCat EV column.

You can switch between displaying by Return Periods and EP Value, and you can edit or add EP points to the table (by clicking and then editing the values in the Edit Summary EP Points dialog box. After editing or adding points, click Reorder & Apply or click OK.) The values are not persisted beyond the immediate Touchstone session.

Usage Notes

       If an analysis was run with reinsurance, you can view the Summary EP Table by treaty. To do this, click Treaty in the View By area on the Loss Results ribbon. This adds a new row to the Summary EP Table so that you can see all applicable perspectives, along with Agg/Occ data and the various EP curve types. Click here for a table that summarizes the distinctions between portfolio- and treaty-specific terms.

       If the analysis was run on Property exposures and results were saved by Coverage and Claims, you can view losses by total coverage or by individual coverage, and you can view the total claim count by clicking Claims. If the analysis was run on Workers' Compensation exposures and results were saved by Claims and Injury Type, you can view losses by total injuries or by individual injury types; click Claims to view the total injury count for the selected injury types.

       If you ran a contract loss analysis and selected Pre-Layer Gross as a loss perspective and selected Save Loss By > Layer, you can view the pre-layer gross results by selecting View By > Layer.

       You can also view TVaR by coverage.
