To embed the seesaw mechanism in the MSSM, two or three right-handed neutrino supermultiplets, $N_i$, have to be added to the model. In this framework, the supersymmetry breaking potential will include a new term called neutrino $B$-term: $MB_\nu \tilde{ N} \tilde{ N}/2$. In this talk, we present a toy model that generates a large neutrino $B$-term keeping other supersymmetry breaking parameters small. We then review the consequences of having a large neutrino $B$-term on the electroweak symmetry breaking parameters and electric dipole moments (EDMs) of elementary particles.
