Plum estimated the weighted average cost of capital (WACC) for broadcast transmission services on a ten year forward looking basis for the Office of the Adjudicator Broadcast Transmission Services. The assessment took into account differences between broadcast transmission and other regulated industries including the existence of long-term contracts and future risks to broadcast transmission due growing platform competition and competition for spectrum inputs. The Adjudicator published the report as an input to an assessment of the appropriate WACC.
