ISO announces that filings have begun for an optional rating rule that uses the output of the by-peril predictive model developed by ISO. The predictive model is known as ISO Risk Analyzer Homeowners. ISO recently began the regulatory filing process and expects to complete the process for several states at a time over the coming months.

ISO Risk Analyzer Homeowners is a set of predictive models that help insurers to classify and segment risks. The environmental module predicts expected losses at a much more refined geographic level than traditional territories. The module also determines expected losses separately by major peril, including wind, fire, lightning, liability, theft and vandalism, hail, water related to weather, water not related to weather, and all other perils for a base risk. In addition, the model can aggregate the by-peril expected losses to an all perils combined basis.
