The pool shall determine a standard risk rate by actuarially calculating the individual rate that an insurer would charge for an individual policy with the pool benefits issued to a person who was a standard risk. Separate schedules of standard risk rates based on age and other appropriate demographic characteristics may be used. In determining the standard risk rate, the pool shall consider the benefits provided, the standard risk experience and the anticipated expenses for a standard risk for the coverage provided. The rates charged for pool coverage shall be no more than one hundred fifty percent of the standard risk rate for each class of insureds.
