Costs

1. The cost to purchase service credit must be calculated by applying actuarial factors to the amount of the retirement and retiree health insurance credit being purchased by the contributor or member of an alternative retirement system. The contributor's current age, average salary, and current credited service on record with the North Dakota public employees retirement system in the month in which the contributor's written request is processed by the office must be used in the cost calculation. A member's written request must be processed by the office within sixty days of receipt. The amount of retirement and retiree health insurance credit benefits being purchased must be calculated using the benefit formulas in place at the time the written request from the contributor is processed by the office. Whenever calculating the cost, enhancements to the benefit formula must be considered to be in place at the time the law is signed by the governor. 2. The member's average salary shall be calculated as follows: a. For members working full time with more than twelve months of service credit, by using the calculation found in subsection 2 of North Dakota Century Code section 39-03.1-11. b. For members working full time with less than twelve months of service credit, by using the calculation found in subsection 2 of North Dakota Century Code section 39-03.1-11, but disregarding any month in which the member was paid less than a full-month salary. A full-month salary is the compensation the member and the member's employer agreed the member would be paid for working a full month. c. For members who have not yet received a full-month salary, the member's average salary shall equal the member's full-month salary, as defined in subsection 2. d. For members working part time, by using the applicable calculations found in subsections 1 and 2, but using a monthly salary equal to the equivalent of the salary the member would have received if the member was working full time. 3. The board must adopt actuarial assumptions necessary to determine the actuarial factors for the cost calculation. The assumptions must be reviewed concurrently with the assumptions for the retirement program. 4. Upon receipt of the written request from the contributor, a written cost confirmation must be prepared and mailed to the individual. The cost stated in the confirmation letter is valid for a period of ninety days from the date of the letter unless the contributor terminates employment with the employer. If the contributor terminates employment, then the cost stated in the confirmation letter is valid only until the earlier of the end of the ninety-day period or the fifteenth day of the month following the month of termination.
