Actuarial factors - Maximum benefits under section 415

In computing the maximum benefits under Internal Revenue Code section 415, as required under North Dakota Century Code section 15-39.1-10.6, the following actuarial assumptions must be used: 1. Interest rate - the interest rate assumption must be the same as the rate that is used in computing actuarially equivalent optional payment forms under section 82-05-04-02 except that: a. The interest rate assumption may not be less than five percent for the purposes of converting the maximum retirement income to a form other than a straight life annuity with no ancillary benefits; b. The interest rate assumption may not be greater than five percent for the purposes of adjusting the maximum retirement income payable to a member who is over age sixty-five so that it is actuarially equivalent to such a retirement income commencing at age sixty-five; and c. The factor for adjusting the maximum permissible retirement income to a member who is less than age sixty-two years so that it is actuarially equivalent to such a retirement income commencing at age sixty-two years shall be equal to the factor for determining actuarial equivalence for early retirement under section 82-05-04-01 or an actuarially computed reduction factor determined using an interest rate assumption of five percent and the mortality assumptions specified in this section (except that the mortality decrement must be ignored if a death benefit at least equal to the single-sum value of the member's accrued benefit would be payable under the fund on behalf of the member if the member remained in service and the member's service was to be terminated by reason of the member's death prior to the member's normal retirement date), whichever factor will provide the greater reduction. The factor for determining actuarial equivalence for early retirement under the fund for any given age below age sixty-two years must be determined by dividing the early retirement adjustment factor that applies under section 82-05-04-01 at such given age by the early retirement adjustment factor that applies under the fund at age sixty-two years. The actuarial adjustment provided in this subdivision does not apply for limitation years beginning after 1994 to income received as a pension, annuity, or similar allowance as a result of a member's disability due to personal injuries or sickness, or amounts received as a result of a member's death by the member's beneficiaries, survivors, or estate. 2. Mortality - the mortality assumptions must be based upon the mortality table prescribed by the secretary of the treasury of the United States pursuant to Internal Revenue Code section 415(b)(2)(E).
