                      strongly correlated systems away from the linear-response
                      regime are of topical interest. In this article, we review
                      the renormalized perturbation theory, or renormalized SPT of
                      reference [1] for the Anderson model. We present an
                      extension to higher orders and compare the higher-order
                      results with NRG calculations. Finally, we elucidate the
                      role of Ward identities in calculating out-of-equilibrium
                      properties and address claims made in the literature.},
