Storm Surge options

You can include an estimate of the separately modeled storm surge losses when calculating losses for tropical cyclone events. Storm surge is an abnormal rise in sea level accompanying a hurricane or other storm.

New Detailed Loss Analysis > Analysis Settings > Storm Surge (AIR) > Storm Surge options dialog box

Administration Console > Object Management > Loss Analysis Template > Analysis Settings > Storm Surge (AIR) > Storm Surge options dialog box

Note: Storm surge does not apply to workers' compensation policies.

The dialog box contains the following fields and buttons that enable you to set the storm surge percentage for each line of business (LOB) associated with the target for a catastrophe peril analysis. You can specify a single storm surge percentage that applies to the entire analysis or you can specify a storm surge percentage by individual LOBs. You can set defaults in the Administration Console.


Field	Description
Single Storm Surge %	Select this option, specify the percentage to apply to the entire analysis, and then click Apply.
Storm Surge % by LOB	Select this option, specify percentage by LOB, and then click Apply.
Total Records	Displays the total number of LOBs associated with the target or targets for the selected detailed loss analysis.
Line of Business	Displays each line of business associated with the target or targets for the analysis. You can specify a percentage for each LOB in the corresponding percentage field. The LOB values come from the selected analysis targets.
Storm Surge %	Specifies the percentage of storm surge leakage for a line of business, meaning the percentage of tropical cyclone loss due to storm surge that is covered by the policy. For example, a value of 5% means that a hurricane policy covers 5% of the loss due to storm surge in addition to the loss due to wind. If you coded your exposure data for storm surge (using peril codes PSH, PWH+PSH, or PAL) before importing the data into Touchstone, then Touchstone applies 100% of the modeled storm surge losses to the analysis. This overrides the default AIR storm surge assumption or any user-specified storm surge percentage. The default storm surge percentage varies by country and line of business. If a property is covered for wind losses and for storm surge losses by different policies, you must model the property in Touchstone as two separate properties. Touchstone cannot apply different policy terms to the same location. Therefore, the best practice is to create a duplicate location, applying only the wind policy to the original location and only the storm surge policy to the duplicate location. Combine the two results in a Loss Group Analysis.
