Abstract: The contribution to precision electroweak measurements due to TeV physics which couples primarily to the ${\mathit{W}}^{\ifmmode\pm\else\textpm\fi{}}$ and Z bosons may be parametrized in terms of the three ``oblique correction'' parameters, S, T, and U. We extend this parametrization to physics at much lower energies, \ensuremath{\gtrsim}100 GeV, and show that in this more general case neutral-current experiments are sensitive to only two additional parameters. A third new parameter enters into the ${\mathit{W}}^{\ifmmode\pm\else\textpm\fi{}}$ width.
