In accordance with its announcement of May 5, 2004, the Treasury has
ceased publication of its long-term average nominal yield, effective
June 1, 2004. The Treasury commenced publishing this rate on February
19, 2002, coinciding with the discontinuance of its 30-year constant
maturity rate. At that time, the Treasury began to publish an
"extrapolation factor," to allow users to calculate a proxy for the
30-year constant maturity rate. An extrapolation factor will continue
to be published, but, as of June 1, it will be based on an
extrapolation from the 20-year yield curve point. The extrapolation
factor is available at the Treasury website, www.treas.gov/offices/domestic-finance/debt-management/interest-rate/index.html, as reported in footnote 11 of the release.
