Onkyo Ltd manufactures an electric device (YD300) that it uses in several of its products. Onkyo Electronics management is considering whether to continue manufacturing the devices or to buy them from an outside source. The following information is available: a- The company needs 4,000 devices per year. The devices (YD300) can be purchased from an outside supplier at a cost of $16 per device. b- The unit cost of manufacturing the device is $35, computed as follows: 55,000 60,000 Direct materials Direct labor Factory overhead: Variable Fixed Total manufacturing costs Cost per unit ($210,000 = 6,000 devices) 30,000 65,000 $210,000 $ 35 C- Discontinuing the manufacture of devices (YD300) will eliminate all the raw materials and direct labor costs but will eliminate only 80% of the variable factory overhead costs. d- If the devices (YD300) are purchased from an outside source, machinery used in the production of devices will be sold at its book value. Accordingly, no gain or loss will be recognized. The sale of this machinery would also eliminate $4,000 in fixed costs associated with depreciation and taxes. No other reductions in fixed factory overhead will result from discontinuing the production of devices. Required: 1- Determine the incremental cost or benefit of buying the devices (YD300) from the outside supplier. Would you recommend that Onkyo Electronics manufacture the devices or buy them from the outside source? (Prepare a schedule to determine the incremental cost or benefit of buying the devices from outside supplier.) (15 marks) 2- Assume that if the devices (YD300) are purchased from the outside source, the factory space previously used to produce devices (YD300) can be used to manufacture an additional 4,000 electric devices (YD310) per year. Electric devices (YD310) have an estimated contribution margin of S8 per unit. The manufacture of the additional electric devices (YD310) would have no effect on fixed factory overhead. Would this new assumption change your recommendation as to whether to make or buy the devices (YD300)? In support of your conclusion, prepare a schedule showing the incremental cost or benefit of buying the devices (YD300) from the outside source and using the factory space to produce additional devices (YD310).
