Update for Weighted Average Interest Rates, Yield Curves, and Segment Rates

# YIELD CURVE AND SEGMENT RATES

Section 430 specifies the minimum funding requirements that apply to single-employer plans (except for CSEC plans under § 414(y)) pursuant to § 412. Section 430(h)(2) specifies the interest rates that must be used to determine a plan’s target normal cost and funding target. Under this provision, present value is generally determined using three 24-month average interest rates (“segment rates”), each of which applies to cash flows during specified periods. To the extent provided under § 430(h)(2)(C)(iv), these segment rates are adjusted by the applicable percentage of the 25-year average segment rates for the period ending September 30 of the year preceding the calendar year in which the plan year begins.¹ However, an election may be made under § 430(h)(2)(D)(ii) to use the monthly yield curve in place of the segment rates.

Notice 2007-81, 2007-44 I.R.B. 899, provides guidelines for determining the monthly corporate bond yield curve, and the 24-month average corporate bond segment rates used to compute the target normal cost and the funding target. Consistent with the methodology specified in Notice 2007-81, the monthly corporate bond yield curve derived from November 2019 data is in Table 2019-11 at the end of this notice. The spot first, second, and third segment rates for the month of November 2019 are, respectively, 2.04, 3.09, and 3.68.

The 24-month average segment rates determined under § 430(h)(2)(C)(i) through (iii) must be adjusted pursuant to § 430(h)(2)(C)(iv) to be within the applicable minimum and maximum percentages of the corresponding 25-year average segment rates. For plan years beginning before 2021, the applicable minimum percentage is 90% and the applicable maximum percentage is 110%. The 25-year average segment rates for plan years beginning in 2018, 2019, and 2020 were published in Notice 2017-50, 2017-41 I.R.B. 280, Notice 2018-73, 2018-40 I.R.B. 526 and Notice 2019-51, 2019-41 I.R.B. 866, respectively.

Based on § 430(h)(2)(C)(iv), the 24-month averages applicable for December 2019, adjusted to be within the applicable minimum and maximum percentages of the corresponding 25-year average segment rates, are as follows:

# 30-YEAR TREASURY SECURITIES INTEREST RATES

Section 431 specifies the minimum funding requirements that apply to multiemployer plans pursuant to § 412. Section 431(c)(6)(B) specifies a minimum amount for the full-funding limitation described in § 431(c)(6)(A), based on the plan’s current liability. Section 431(c)(6)(E)(ii)(I) provides that the interest rate used to calculate current liability for this purpose must be no more than 5 percent above and no more than 10 percent below the weighted average of the rates of interest on 30-year Treasury securities during the four-year period ending on the last day before the beginning of the plan year. Notice 88-73, 1988-2 C.B. 383, provides guidelines for determining the weighted average interest rate. The rate of interest on 30-year Treasury securities for November 2019 is 2.28 percent. The Service determined this rate as the average of the daily determinations of yield on the 30-year Treasury bond maturing in August 2049 determined each day through November 6, 2019 and the yield on the 30-year Treasury bond maturing in November 2049 determined each day for the balance of the month For plan years beginning in December 2019, the weighted average of the rates of interest on 30-year Treasury securities and the permissible range of rates used to calculate current liability are as follows:

# MINIMUM PRESENT VALUE SEGMENT RATES

In general, the applicable interest rates under § 417(e)(3)(D) are segment rates computed without regard to a 24-month average. Notice 2007-81 provides guidelines for determining the minimum present value segment rates. Pursuant to that notice, the minimum present value segment rates determined for November 2019 are as follows:
