The "maximum permissible benefit" is the defined benefit dollar limitation (adjusted where required, as provided in Subsection 549.01 and, if applicable, in Subsections 549.02 through 549.04 of these rules).
01.Less Than Ten Years of Service. If the participant has fewer than ten (10) years of participation in the plan, the defined benefit dollar limitation shall be multiplied by a fraction:a. The numerator of which is the number of years (or part thereof) of participation in the plan; andb. The denominator of which is ten (10).02.Benefit Begins at Age Sixty-Five. If the benefit of a participant begins after the participant attains age sixty-five (65), the defined benefit dollar limitation applicable to the participant at the later age is the annual benefit payable in the form of a straight life annuity beginning at the later age that is actuarially equivalent to the defined benefit dollar limitation applicable to the participant at age sixty-five (65) (adjusted under Subsection 549.01, if required). The actuarial equivalent of the defined benefit dollar limitation applicable at an age after age sixty-five (65) is determined as set forth in IRS regulation under section 415(b)(2) of the IRS Code.03.Transition. Benefit increases resulting from the increase in the limitations of section 415(b) of the IRS Code shall be provided to all current and former participants (with benefits limited by section 415(b)) who have an accrued benefit under the plan immediately prior to the effective date of this Section (other than an accrued benefit resulting from a benefit increase solely as a result of the increases in limitations under section 415(b)).Idaho Admin.
