The insurer shall not charge the member, and no member of the insurer shall pay to the insurer, in connection with the inception of insurance in the insurer or any renewal or continuation of such insurance, any charge or amount in excess of such amount as may be reasonably necessary for payment of the member’s share of the insurer’s expenses (exclusive of insured losses incurred) to be incurred during the next succeeding twelve (12) months, and for maintenance or replenishment of the emergency fund provided for in section 41-3112(3)[, Idaho Code]. This provision shall not be deemed to prohibit the levy and collection of assessments for payment of incurred losses or for maintenance of the emergency fund, as provided for in section 41-3112[, Idaho Code], nor collection of membership or policy fees in fixed nominal amounts.
