a result of bulk flows. Based on the discussion in Section 8.6 of Freedman [[et al. ]{}]{}(2001) we estimate this systematic component to be less than 2% on the scales $z {\lesssim}0.1$ over which Type Ia supernovae have been used to calibrate $H_0$. This corresponds to a difference $\Delta_{\rm IV} = \pm 0.009$ in $\log(M/L)$. Random uncertainties in $H_0$, as opposed to systematic ones, result from finite sample sizes and scatter between results from individual measurements. Based on Section 7 of Freedman [[et al. ]{}]{}(2001) we estimate the random uncertainty to be $\Delta H_0 = \pm 4 {\>{\rm km}\,{\rm s}^{-1}}{\>{\rm Mpc}}^{-1}$. This corresponds to $\Delta_{\rm V} = \pm 0.023$ in $\log(M/L)$.
