Weighted Average Interest Rate Update

Notice 2006–39

Sections 412(b)(5)(B) and 412(l)(7) (C)(i) of the Internal Revenue Code generally provide that the interest rates used to calculate current liability for purposes of determining the full funding limitation under § 412(c)(7) and the required contribution under § 412(l) must be within a permissible range around 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 and the resulting permissible range of interest rates used to calculate current liability for the purpose of the full funding limitation of § 412(c)(7) of the Code.

Section 417(e)(3)(A)(ii)(II) defines the applicable interest rate, which must be used for purposes of determining the minimum present value of a participant’s benefit under § 417(e)(1) and (2), as the annual rate of interest on 30-year Treasury securities for the month before the date of distribution or such other time as the Secretary may by regulations prescribe. Section 1.417(e)–1(d)(3) of the Income

Tax Regulations provides that the applicable interest rate for a month is the annual interest rate on 30-year Treasury securities as specified by the Commissioner for that month in revenue rulings, notices or other guidance published in the Internal Revenue Bulletin.

The rate of interest on 30-year Treasury securities for March 2006 is 4.73 percent. The Service has determined this rate as the monthly average of the daily determination of yield on the 30-year Treasury bond maturing in February 2036.

The following 30-year Treasury rates were determined for the plan years beginning in the month shown below.

.03 Section 143(f) imposes eligibility requirements concerning the maximum income of mortgagors for whom financing may be provided by qualified mortgage bonds. Section 25(c)(2)(A)(iii)(IV) provides that recipients of mortgage credit certificates must meet the income requirements of § 143(f). Generally, under §§ 143(f)(1) and 25(c)(2)(A)(iii)(IV), these income requirements are met only if all owner-financing under a qualified mortgage bond and all certified indebtedness amounts under a mortgage credit certificate program are provided to mortgagors whose family income is 115 percent
