Rates established by the judgment of the underwriter with or without the application of a formal set of rules or rate schedule.

In insurance, rates established by the underwriter based on his or her experience and somewhat arbitrary decision, with or without the application of a formal set of rules.

Also known as A rates, it is the rates given by the insurer based on an individual's record, and not on a statistical basis. For example, if you are a 19-year-old male with a red sports car, chances are, your rate premium will be pretty high, since statistically, young people are labeled as riskier drivers and red sports car are most likely to be apprehended by the police in event of a traffic violation. However, if you have a stellar driving record and have shown evidence of road responsibility, you will get a lower judgment rate.
