Parts of a .csv step function file

You use the step function files to implement single-location residential endowment policies—primary property only—in Japan. Rather than paying out a continuous amount for damages that occur at a location, policies with step functions define ranges where any damages that fall between "x" and "y" will be paid out at a certain amount. You can also use step functions for any region, peril, or line of business. Step function files contains fields that detail the damage ratios in each of the steps that dictate when certain coverage-specific payouts are made.

Step functions do not apply to facultative or workers' compensation policies.

You link each set of step function records to the policy ID (contract or account) to which the step function applies by including the relevant ID in each step function record. Although you define a set of step function records once for a policy, Touchstone applies the step function to each location within the policy individually.
