N.D. Cent. Code § 15-39.1-10.11
An individual who on June 30, 2001, is receiving monthly benefits from the fund on an account paid under this chapter or under former chapter 15-39 is entitled to receive a monthly increase equal to an amount determined by taking two dollars per month multiplied by the member's number of years of service credit plus one dollar per month multiplied by the number of years since the member's retirement. In addition, an individual who is receiving monthly benefits from the fund on an account paid under this chapter or under former chapter 15-39 is entitled to receive a seventy-five hundredths of one percent increase of the individual's current monthly benefit with the increased benefit payable each month thereafter beginning on July 1, 2001. An individual who on June 30, 2002, is receiving monthly benefits from the fund on an account paid under this chapter or under former chapter 15-39 is entitled to receive a seventy-five hundredths of one percent increase of the individual's current monthly benefit with the increased benefit payable each month thereafter beginning on July 1, 2002. This annual benefit adjustment is conditioned on an actuarial test performed annually by the board's actuarial consultant to determine the actuarial adequacy of the statutory contribution rate. The board shall report the results of the actuarial test annually to the employee benefits programs committee. If the actuarial valuation indicates a shortfall between the actuarially determined benchmark contribution rate and the statutory rate, the board may reduce or suspend the conditional annual benefit adjustment. The actuarial adequacy test fails if one or more of the following are true:
