The commissioner shall annually prorate among and assess all insurers and self-insurers all costs and claims paid under the assigned claims program.
Proration shall be based upon a pro rata distribution for each premium dollar actually or theoretically received. A self-insurer shall be assessed that prorated amount based upon the total premium cost for the coverage and vehicles stated in its certificate of self-insurance, as if the self-insurer had sold such coverage at JUP premium rates.
