Customizing country-specific demand surge

You can customize demand surge for select European models.

Admin > Administration Console > Loss Defaults > Demand Surge > Country-specific

We using a new methodology that is available on the all new Country-specific tab; it applies only to European region models for earthquake, extratropical cyclone, severe thunderstorm, and inland flood (mainland and Great Britain). The new approach involves two components:

  • Core economic demand surge factor – Calculated for each supported model and country in the loss engine and cannot be customized.
  • Post-event construction cost inflation percentage – Can be customized in Admin > Administration Console > Loss Defaults > Demand Surge.

Demand surge factors are calculated by finding the largest industry loss event for each country in each year of each model and determining whether it meets a threshold; if it meets the threshold, a demand surge factor is applied according to a model- and country-specific formula that is a function of that maximum annual industry loss. The construction cost inflation factor is then added to the core economic demand surge factor. This construction cost inflation factor is defaulted to the long term average of 3.0%, but can be customized by country.

The Country-specific tab includes only one region at this time, Europe. Select this tab to access select European models and use the new country-specific-all-events demand surge methodology. The selection Europe_Southeast supports Albania, Macedonia, and Serbia as one group rather than as separate countries. You cannot make changes to the default list on this tab.

To customize the demand surge for a country, create a new list and then set the regional factor and customize the inflation numbers. You can also use the buttons to the right of the tab to import or export data.

Users can exclude certain exposures and LOBs. Click Exposure Exclusions and enter construction codes, occupancy codes, and/or LOBs.
