  We apply a recently developed 1/(N-1) expansion to the full counting
statistics for the N-fold degenerate Anderson impurity model in the Kondo
regime. This approach is based on the perturbation theory in the Coulomb
interaction U and is different from the conventional large N theories, such as
the usual 1/N expansion and non-crossing approximation. We have confirmed that
the calculations carried out up to order 1/(N-1)^2 agree closely with those of
the numerical renormalization group at N=4, where the degeneracy is still not
so large. This ensures the applicability of our approach for N>4. We present
the results of the cumulants of the probability distribution function for a
nonequilibrium current through a quantum dot in the particle-hole symmetric
case.
