The reducible background ($\PZ + \mathrm{X}$) is evaluated using the method based on lepton misidentification probabilities and control regions in data, following the procedure described in Ref. [@Chatrchyan:2013mxa]. In the case of the integrated ${\ensuremath{\PH \to 4\ell}\xspace}$ cross section measurement, the shape of the $m_{4\ell}$ distribution for the reducible background is obtained by fitting the $m_{4\ell}$ with empirical analytical functional forms presented in Ref. [@Chatrchyan:2013mxa]. In the case of the differential ${\ensuremath{\PH \to 4\ell}\xspace}$ measurements, the shapes of the reducible background are obtained from the control regions in data in the form of template functions, separately for each bin of the considered observable. The template functions are prepared following a procedure described in the spin-parity studies presented in Refs. [@Chatrchyan:2013mxa; @Khachatryan:2014kca].
