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 2020 is 1.62 percent. The Service determined this rate as the average of the

daily determinations of yield on the 30year Treasury bond maturing in August 2050 determined each day through November 10, 2020 and the yield on the 30-year Treasury bond maturing in November 2050 determined each day for the

balance of the month. For plan years beginning in December 2020, 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:

Permissible Range

90% to 105%

Treasury Weighted Average Rates For Plan Years 30-Year Treasury

Beginning In

30-Year Treasury Weighted Average

December 2020 2.35 2.11 to 2.47

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 pres

ent value segment rates. Pursuant to that notice, the minimum present value segment rates determined for November 2020 are as follows:

Minimum Present Value Segment Rates Month First Segment Second Segment Third Segment November 2020 0.53 2.31 3.09
