In a number of regulated industries ACM has a role in tariff setting. For this, the ACM needs to determine the reasonable return to set tariffs for incumbents in regulated markets, such as the telecommunication market, electricity market, gas market, pilotage market, et cetera. The ACM sets this reasonable return by calculating the Weighted Average Cost of Capital (WACC). Since the WACC is an important element when setting tariff, as well as an element of specific and varied regulatory methods, the ACM regularly needs advice to determine (parameters of) the WACC.
