Part III --- Administrative, Miscellaneous, and Procedural

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

Notice 2018-11

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

Generally, except for certain plans under section 104 of the Pension Protection Act of

2006 and CSEC plans under § 414(y), § 430 of the Code specifies the minimum funding

requirements that apply to single-employer plans 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 December

2017 data is in Table 2017-12 at the end of this notice

-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 December

2017 data is in Table 2017-12 at the end of this notice. The spot first, second, and third

segment rates for the month of December 2017 are, respectively, 2.33, 3.55, and 4.11.

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

2016, 2017, and 2018 were published in Notice 2015-61, 2015-39 I.R.B. 408, Notice 2016-54,

2016-40 I.R.B. 429, and Notice 2017-50, 2017-41 I.R.B. 280, respectively.

1 Pursuant 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))

408, Notice 2016-54,

2016-40 I.R.B. 429, and Notice 2017-50, 2017-41 I.R.B. 280, respectively.

1 Pursuant 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)).

24-MONTH AVERAGE CORPORATE BOND SEGMENT RATES

The three 24-month average corporate bond segment rates applicable for January 2018

without adjustment for the 25-year average segment rate limits are as follows:

Based on § 430(h)(2)(C)(iv), the 24-month averages applicable for

Based on § 430(h)(2)(C)(iv), the 24-month averages applicable for January 2018,

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

Generally for plan years beginning after 2007, § 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 December 2017 is 2.77

percent. The Service determined this rate as the average of the daily determinations of yield on

the 30-year Treasury bond maturing in November 2047

d 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 December 2017 is 2.77

percent. The Service determined this rate as the average of the daily determinations of yield on

the 30-year Treasury bond maturing in November 2047. For plan years beginning in January

2018, 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 December 2017 are as follows:
