The Superintendent of Insurance approves rating factors that insurers may use to set their rates, such as where an individual lives and their years of driving experience, among others. In addition, the independent rate regulator, the AIRB, reviews auto insurers’ proposed rate changes, including actuarial assumptions such as projected claims cost increases, operating expenses and maximum permitted profit margins. Based on those factors, it makes a decision on insurers’ requested rate changes. AIRB full rate filing guidelines can be found here.
This process takes at least 90 days from the time an insurer submits a rate filing to when the first consumer sees the rate change.
