Modifiers in mind map

Rate modifiers are used to adjust a policy's premium based on a set of risk characteristics, as described in Rate modifiers.

Unscheduled rate modifier

A rate modifier that does not have multiple rate factors is called an unscheduled rate modifier. For example, an experience modifier, often used in commercial lines of business, is modeled as an unscheduled rate modifier. This modifier has a minimum value of -0.5 and a maximum value of 0.5.

  • Employee Qualifications (-0.06 to 0.06)
The IRPM modifier has an overall minimum of -0.25 and maximum of 0.25.
