  Recently we studied inflation models in which the inflaton potential is
characterized by an underlying approximate global symmetry. In the first work
we pointed out that in such a model curvature perturbations are generated after
the end of the slow-roll phase of inflation. In this work we develop further
the observational implications of the model and compute the degree of
non-Gaussianity predicted in the scenario. We find that the corresponding
nonlinearity parameter, $f_{NL}$, can be as large as 10^2.
