Thornton Radio Corporation is a subsidiary of Salem Companies. Thornton makes car radios that it sells to retail outlets. It purchases speakers for the radios from outside suppliers for $55 each. Recently, Salem acquired the Campbell Speaker Corporation, which makes car radio speakers that it sells to manufacturers. Campbell produces and sells approximately 270,000 speakers per year, which represents 70 percent of its operating capacity. At the present volume of activity, each speaker costs $43 to produce. This cost consists of a $29 variable cost component and an $14 fixed cost component. Campbell sells the speakers for $60 each. The managers of Thornton and Campbell have been asked to consider using Campbell's excess capacity to supply Thornton with some of the speakers that it currently purchases from unrelated companies. Both managers are evaluated based on return on investment. Campbell's manager suggests that the speakers be supplied at a transfer price of $60 each (the current selling price). On the other hand, Thornton's manager suggests a $55 transfer price, noting that this amount covers total cost and provides Campbell a healthy contribution margin. Required a.
