1 Taxable bonds are those on which the interest is subject to both the normal and
surtax rates of the Federal income tax. This average commenced Oct. 20, 1941.

Prior to October 1941 yields were on partially tax-exempt long-term bonds. For
January 1930 through December 1945, see the 1956 Annual Report, page 492, and for
January 1919 through December 1929, see the 1943 Annual Report, p. 662.

Beginning Oct. 20, 1941, through Mar. 31, 1952, yields are based on bonds neither
due nor callable for 15 years; beginning Apr. 1, 1952, through Mar. 31, 1953, on bonds
neither due nor callable for 12 years; beginning Apr. 1, 1953, on bonds neither due nor
callable for 10 years.

NOTE.-For bonds selling above par and callable at par before maturity, the yields
are computed on the basis of redemption at first call date; while for bonds selling below
par, yields are computed to maturity. Monthly averages are averages of daily figures.
Each daily figure is an unweighted average of the yields of the individual issues. Yields
before 1953 are computed on the basis of the mean of closing bid and ask quotations in
the over-the-counter market. Commencing April 1953, yields, as reported by the Federal
Reserve Bank of New York, are based on over-the-counter closing bid quotations.
See Treasury Bulletin for current monthly yields.
