Interest Rates, Yield Curves, Segment Rates Updated for September

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

Part III — Administrative, Miscellaneous, and Procedural

This notice provides guidance on the corporate bond monthly yield curve, the corresponding spot segment rates used under § 417(e)(3), and the 24-month average segment rates under § 430(h)(2) of the Internal Revenue Code. In addition, this notice provides guidance as to the interest rate on 30-year Treasury securities under § 417(e)(3)(A)(ii)(II) as in effect for plan years beginning before 2008 and the 30-year Treasury weighted average rate under § 431(c)(6)(E)(ii)(I).

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 August 2022 data is in Table 2022-8 at the end of this notice. The spot first, second, and third segment rates for the month of August 2022 are, respectively, 3.79, 4.62, and 4.69.

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. The 25-year average segment rates for plan years beginning in 2021 and 2022 were published in Notice 2020-72, 2020-40 I.R.B. 789, and Notice 2021-54, 2021-41 I.R.B. 457, respectively. For plan years beginning in 2023, based on the segment rates applicable for October 1997 to September 2022, the 25-year averages for the period ending September 30, 2022, of the first, second, and third segment rates are 3.48, 5.26, and 6.04 percent, respectively.

24-MONTH AVERAGE CORPORATE BOND SEGMENT RATES

The three 24-month average corporate bond segment rates applicable for September 2022 without adjustment for the 25-year average segment rate limits are as follows:

25-YEAR AVERAGE SEGMENT RATES

Section 9706(a) of the American Rescue Plan Act of 2021, Pub. L. 117-2 (the ARP), which was enacted on March 11, 2021, changed the 25-year average segment rates and the applicable minimum and maximum percentages used under § 430(h)(2)(C)(iv) of the Code to adjust the 24-month average segment rates.² Prior to this change, the applicable minimum and maximum percentages were 85% and 115% for a plan year beginning in 2021, and 80% and 120% for a plan year beginning in 2022, respectively. After this change, the applicable minimum and maximum percentages are 95% and 105% for a plan year beginning in 2021 or 2022. In addition, pursuant to this change, any 25-year average segment rate that is less than 5% is deemed to be 5%.³

Pursuant to § 9706(c)(1) of the ARP, these changes apply with respect to plan years beginning on or after January 1, 2020. However, § 9706(c)(2) of the ARP provides that a plan sponsor may elect not to have these changes apply to any plan year beginning before January 1, 2022.⁴

The adjusted 24-month average segment rates set forth in the chart below reflect § 430(h)(2)(C)(iv) of the Code as amended by § 9706(a) of the ARP. These adjusted 24-month average segment rates apply only for plan years for which an election under § 9706(c)(2) of the ARP is not in effect. For a plan year for which such an election does not apply, the 24-month averages applicable for September 2022, adjusted to be within the applicable minimum and maximum percentages of the corresponding 25-year average segment rates in accordance with § 430(h)(2)(C)(iv) of the Code, are as follows:

The adjusted 24-month average segment rates set forth in the chart below do not reflect the changes to § 430(h)(2)(C)(iv) of the Code made by § 9706(a) of the ARP. These adjusted 24-month average segment rates apply only for plan years for which an election under § 9706(c)(2) of the ARP is in effect. For a plan year for which such an election applies, the 24-month averages applicable for September 2022, adjusted to be within the applicable minimum and maximum percentages of the corresponding 25-year average segment rates in accordance with § 430(h)(2)(C)(iv) of the Code, 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 August 2022 is 3.13 percent. The Service determined this rate as the average of the daily determinations of yield on the 30-year Treasury bond maturing in May 2052 determined each day through August 10, 2022 and the yield on the 30-year Treasury bond maturing in August 2052 determined each day for the balance of the month. For plan years beginning in September 2022, 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 August 2022 are as follows:
