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).

In addition to providing these rates for current periods, this notice provides 24-month average segment rates for earlier periods for plan years beginning in 2020 and 2021, determined under § 430(h)(2)(C)(iv) of the Code reflecting the modifications made by § 9706(a) of the American Rescue Plan Act of 2021, Pub. L. No. 117-2 (ARP), which was enacted on March 11, 2021.

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 March 2021 data is in Table 2021-3 at the end of this notice. The spot first, second, and third segment rates for the month of March 2021 are, respectively, 0.69, 2.92, and 3.69.

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 2020 and 2021 were published Notice 2019-51, 2019-41 I.R.B. 866, and Notice 2020-72, 2020-40 I.R.B. 789, respectively.

24-MONTH AVERAGE CORPORATE BOND SEGMENT RATES

The three 24-month average corporate bond segment rates applicable for March 2021 without adjustment for the 25-year average segment rate limits are as follows:

Section 9706(a) of ARP changes the 25-year average segment rates and the applicable minimum and maximum percentages used under § 430(h)(3)(C)(iv) of the Code to adjust the 24-month average segment rates. Prior to this change, the applicable minimum and maximum percentages were 90% and 110% for a plan year beginning in 2020, and 85% and 115% for a plan year beginning in 2021, respectively. After this change, the applicable minimum and maximum percentages are 95% and 105% for a plan year beginning in 2020 or 2021. In addition, pursuant to this change, any 25-year average segment rate that is less than 5% is deemed to be 5%.2

Pursuant to § 9706(c)(1) of ARP, these changes apply with respect to plan years beginning on or after January 1, 2020. However, § 9706(c)(2) of ARP provides that a plan sponsor may elect not to have these changes apply to any plan year beginning before January 1, 2022.3

The adjusted 24-month average segment rates reflecting § 430(h)(2)(C)(iv) of the Code as amended by § 9706(a) of ARP for January 2020 through March 2021, applicable for plan years beginning in 2020 and 2021, are set forth in the Appendix.

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 ARP. These adjusted 24-month average segment rates apply only for plan years for which an election under § 9706(c)(2) of ARP is not in effect. For a plan year for which such an election does not apply, the 24-month averages applicable for April 2021, 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 ARP. These adjusted 24-month average segment rates apply only for plan years for which an election under § 9706(c)(2) of ARP is in effect. For a plan year for which such an election applies, the 24-month averages applicable for April 2021, 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 March 2021 is 2.34 percent. The Service determined this rate as the average of the daily determinations of yield on the 30-year Treasury bond maturing in February 2051. For plan years beginning in April 2021, 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:

Treasury Weighted Average Rates

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 March 2021 are as follows:

FOOTNOTES

1Pursuant to § 433(h)(3)(A), the 3rd segment rate determined under § 430(h)(2)(C) is used to determine the current liability of a CSEC plan (which is used to calculate the minimum amount of the full funding limitation under § 433(c)(7)(C)).

2Pursuant to this change, the 25-year averages of the first segment rate for 2020 and 2021 are increased to 5.00% because those 25-year averages as originally published are below 5.00%.

3This election may be made either for all purposes for which the amendments under § 9706 of ARP apply or solely for purposes of determining the adjusted funding target attainment percentage under § 436 of the Code for the plan year.
