(1) The IARA assessment upon each insurer is calculated on the total amount of compensation paid each year by the insurer for Montana claims. For the purpose of this rule, the phrase "compensation paid" means the same as provided by ARM  24.29.954(2) .

(2) The department will set the percentage rate of the IARA assessment at a level that is projected to produce funding equal to the last year's payout, plus or minus the percentage change between the number of qualified claimants accessing IARA funding in the two prior years, but not to exceed 1% of compensation paid.

(3) All insurers operating in the same plan will be assessed the same percentage rate, regardless of whether or not that particular insurer requested funds pursuant to 39-71-1003 , MCA. Because the IARA assessments paid by each of the three compensation plans are segregated by plan, the department may assess plan No. 1 insurers at a different rate than plan No. 2 insurers or the plan No. 3 insurer.

(4) In the event that there is a supplemental IARA assessment, it will be due within 30 days of the billing date.
