Abstract
In this article, we review the theory and the experimental status of inclusive semileptonic B meson decays B -> Xc l nu. Based on these inputs, we present the latest determination of the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element |V_cb| and of the b-quark mass m_b, obtained by the Heavy Flavor Averaging Group (HFAG).
