As of the release dated February 25, 2002, the H.15 no longer reports a 30-year constant maturity yield for Treasury securities and begins reporting a yield for Treasury securities with 25 years or more remaining to maturity. The changes reflect the Treasury's announcement on January 30, 2002, that, effective February 18, it would cease supplying an estimate of the 30-year constant maturity yield and that it would commence supplying a long-term yield based on a basket of long-dated securities. As indicated in footnote 12 of the release, the new long-term rate is based on an unweighted average of the bid yields for all Treasury fixed-coupon securities with remaining terms to maturity of at least 25 years. A factor to adjust the daily long-term average to estimate a 30-year rate is available at the Treasury web site reported in footnote 13 of the release.
