Damage factor files

A Damage Factor File (DFF) is a CSV file that is used to customize losses during an analysis. You can create multiple DFFs.

To use the Touchstone Re Damage Function feature, you need a minimum of two ASCII files:

  • Base Damage Factor File (DFF)

  • Damage Function Mapping file (map)

The DFF is mapped to the Damage Function Mapping file. The Damage Function feature cross-references the damage factor from the DFF to the map file to modify the obtained unique damage function.

Usage Notes

  • Fields in the DFF may contain placeholders of zero for damage factors, for every event in the model's catalog.

  • Touchstone Re creates a separate sample file record for every area and subarea that has industry loss in the Verisk catalog. The sample file contains placeholders for all (20) potential custom LOBs (Lines of Business).

  • To customize a custom damage factor file, enter the damage ratio percentage in the appropriate LOB column.

  • The Damage Function feature interprets values as percentages: 1.15 corresponds to a damage factor of 1.15% of custom sums insured.

  • The feature supports decimal precision up to seven places to the right of the decimal point.

  • The actual LOB names do not appear in the CSV file.

  • You do not have to include every event and records included in the sample DFF file in a customized file. For example, the North Atlantic hurricane model sample DFF file contains records for all Caribbean and Central American countries, the United States, and the Gulf of Mexico (offshore oil platform protractions). You can exclude area/subarea records for countries for which you do not want to apply damage factors. You can also exclude events for which you do not want to calculate loss for customs sums insured.
