Description
The value of electroweak contribution to the ratio between
pole and MSbar masses of top-quark are discussed. We argue that
for a Higgs boson mass M_H ~ 125 GeV,
the electroweak contribution are large and have opposite
sign relative to the QCD contribution
so that the total correction is small and approximately equal to 1 GeV.
This fact reduces the scheme dependence for any top-dependent observables.
