Each year the director shall determine the amount of the levy to be paid by each insurer or employer and shall give notice of the levy to each such insurer or employer on or before May 1 of the year in which the levy is assessed. The amount of the levy shall be paid on or before June 30 following notification.
The amount of the levy against each insurer or employer shall be determined as the product of the wages paid by the employer multiplied by a factor which is the ratio of the amount by which the balance in the [trust fund for disability benefits] was less than $500,000 on the preceding December 31 to total covered wages paid by all employers.
