  No gauge invariant regularization is available for the perturbative
calculation of the standard model. One has to add finite counter terms to
restore gauge symmetry for the renormalized amplitudes. The muon anomalous
magnetic moment can be accurately measured but the experimental result does not
entirely agree with the theoretical calculation from the standard model. This
paper is to compute the contributions to the muon gyromagnetic ratio $g_{\mu}$
due to the finite counter terms. The result obtained is found to be far from
sufficient to explain the discrepancy between theory and experiment.
