The face value of matured savings bonds and savings notes outstanding is included until all of the annual series have matured, when the entire amount is transferred to matured debt on which interest has ceased. Comparable annual data 1916-38 are contained in 1962 Annual Report, p. 735. Current monthly figures are published in the Treasury Bulletin. Comparable monthly data 1929-36 appear in 1936 Annual Report, p. 442, and from 1937 in later reports. Annual interest charge monthly 1916-29 appears in 1929 Annual Report, p. 509. NOTE.-The computed annual interest charge represents the amount of interest that would be paid if each interest-bearing issue outstanding at the end of the month or year should remain outstanding for a year at the applicable annual rate of interest. The charge is computed for each issue by applying the appropriate annual interest rate to the amount outstanding on that date. Beginning Dec. 31, 1958, the computed average rate is based upon the rate of effective yield for issues sold at premiums or discounts. Before that date the computed average rate was based upon the coupon rates of the securities. That rate did not materially differ from the rate on the basis of effective yield. The "effective yield" method of computing the average interest rate on the public debt more accurately reflects the interest cost to the Treasury, and is believed to be in accord with the intent of Congress where legislation has required the use of the rate of effective yield for various purposes. TABLE 47.-Computed annual interest rate and computed annual interest charge on the public debt by classes, June 30, 1950-72 [Dollar amounts in millions. On basis of daily Treasury statements, see "Bases of Tables"] •Less than $500,000. Total includes Panama Canal bonds prior to 1961, and postal savings bonds prior to 1956. Included in debt outstanding at face amount, but the annual interest charge and the annual interest rate are computed on the discount value. The annual interest charge and annual interest rate on United States savings bonds and United States savings notes are computed on the basis of the rate to maturity applied against the amount outstanding. NOTE. For methods of computing annual interest rate and charge see note to table 46. See table 26 for amounts of public debt outstanding by classification.
