The eleven ULIRGs with L_FIR > 10^12.5 L_Sun south of Dec = -12 deg were observed with integration times that varied between 5 and 24 hours. Four marginal detections were obtained for individual targets in the sample. The \"stacked\" spectrum of the entire sample yields a high significance, 10{\\sigma} detection of the CO(1-0) transition at an average redshift of z = 0.38.
