"Threshold wage" means the wage amount the employer pays unemployment taxes on for each person in his or her employ during a calendar year. On and after the effective date of the amendment and reenactment of this chapter by the Legislature in 2009, the threshold wage will be $12,000: Provided, That when the moneys in the unemployment fund reach $220 million on February 15 of any year, the threshold wage thereafter will be reduced to $9,000: Provided, however, That each year thereafter the threshold wage shall increase or decrease by the same percentage that the state's average wage increases or decreases.
