INVESTING ACTIVITIES Fiscal 2019 fourth-quarter investing activities decreased by 25.8% compared to the same period of the prior year mainly due to the acquisition of spectrum licenses in the Canadian broadband services segment in the comparable period of the prior year combined with a decrease in acquisitions of property, plant and equipment.
