T.D. 9983

These regulations prescribe mortality tables to be used for most defined benefit pension plans. The tables specify the probability of survival year-by-year for an individual based on age, gender, and other factors. The tables are used (together with other actuarial assumptions) to calculate the present value of a stream of expected future benefit payments for purposes of determining the minimum funding requirements for the plan. These mortality tables are also relevant for determining the minimum required amount of a lump-sum distribution from such a plan. 26 CFR 1.430(h)(3)-1; 26 CFR 1.431(c)(6)-1; 26 CFR 1.433(h)(3)-1

These proposed regulations would update the requirements that a plan sponsor of a single-employer defined benefit plan must meet to obtain IRS approval to use mortality tables specific to the plan in calculating present value for minimum funding purposes (as a substitute for the generally applicable mortality tables).
