Ins 17.25(12)(a)5.a. a. In establishing the plan’s rates, the board shall use loss and expense experience in this state to the extent it is statistically credible supplemented by relevant data from outside this state including, but not limited to, data provided by other insurance companies, rate service organizations or governmental agencies.
