*** Test *** Discontinuance of Treasury Long-Term Average Nominal Rate
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,, as reported in footnote 11 of the release.
