Description

Validation Rules

Default Value

Trigger Type

One of the following trigger type values. The Description column indicates how, and for which coverages, payouts are triggered:

Building (1)

Building and contents payouts are based only on building damage.

Contents (2)

Building and contents payouts are based only on contents damage.

Building and Contents (3)

Payout is based on combined building and contents damage.

Building, then Contents (4)

Payout is based on building damage if the loss is greater than or equal to the building trigger. Otherwise, if contents damage is triggered, payout is based on contents damage.

Users can enter values in the ContentStart and ContentEnd fields in the exposure data for import into Touchstone. The values are then visible in the Trigger by Amount section in the Content Start and Content End fields for trigger type 4 (Building, then Contents). This enables users to specify contents amount steps in addition to building amount steps for building damage, not just percentage and amount steps.

Building, Contents separately (5)

Building payout is based on building damage, and contents payout is based on contents damage.

  • Defaults to a value in the Touchstone user interface

  • Must be an integer value between 1 and 5, inclusive, when importing data
