The case of spontaneous CP violation for large mt is reanalyzed and the validity of perturbation theory is checked by calculating the second order corrections to the CKM matrix. For a very large right-handed mass scale, the perturbation theory breaks down in some cases. While in other cases consistent with perturbation theory, the model predicts too large ε′/ε. Two possible alternatives are: (a) models with low right-handed mass scales with three generations and (b) models with heavy right-handed mass scales with four generations, avoid the above problems and values of ε′/ε and electric dipole moment of the neutron consistent with present data are obtained.
