8169 - Determination of net interest cost and net interest rate.

     § 8169.  Determination of net interest cost and net interest                rate.        (a)  Net interest cost.--Net interest cost may be determined     by using either the street method or the present worth method,     whichever method shall be specified in the official notice of     sale.        (b)  Street method.--Under the street method, a dollar amount     shall be determined by computing the total amount of interest     payable over the life of the series to stated maturity dates or     earlier mandatory call dates and subtracting therefrom the     amount of any premium paid above the aggregate principal amount     of the bonds or notes or adding thereto the amount of any     discount lawfully allowed in the sale.        (c)  Present worth method.--Under the present worth method,     there shall be ascertained the semiannual rate, compounded     semiannually, necessary to discount to present worth as of the     date of the bonds or notes, the amounts payable on each interest     payment date and on each stated maturity or earlier mandatory     redemption date so that the aggregate of such amounts will equal     the purchase price offered therefor, exclusive of interest     accrued to the date of delivery. The net interest cost shall be     stated in terms of an annual percentage rate and shall be that     rate of interest which is twice the semiannual rate so     ascertained.        (d)  Net interest rate.--The net interest rate for a series     sold under the present worth method shall be the rate of the net     interest cost. For a series sold under the street method, the     net interest rate shall be determined by dividing the net     interest cost by the product of $1,000 multiplied by the number     of bond years from the date of the bonds or notes to the stated     maturity or earlier mandatory call dates. A bond year shall be     one full year that $1,000 of principal amount shall be     outstanding and less than full years shall be fractionalized on     a 360-day-year basis.        Cross References.
