b. Provide one reason why using the payback period can result in the firm making a sub-optimal decision. Question: 2.9 – Global Manufacturing Global Manufacturing is a Canadian company that processes a wide range of natural resources. Two years ago the company acquired Zeta Manufacturing, a raw material processing firm located in the United States. Over the last year, profits have fallen in the U.S.-based subsidiary. Laura Hammon, the Manager of Manufacturing Accounting for Zeta Manufacturing, has been asked to identify the problems that have impaired the firm’s profits. She has reviewed the monthly production cost reports and discovered that the per unit costs have been consistently increasing over the last year. Since the subsidiary used an actual cost system, Hammon convinced the president and the production manager that a thorough assessment of each product’s cost and the implementation of a standard cost system would help to solve the problem. Within six months, Hammon installed a fully operational standard cost system for the division. After several months of using the new cost system, Hammon is perplexed by unexplainable efficiency and yield variances, which result in material inventory write-downs at the end of each month. The work- in-process account is charged with the actual input costs of direct materials and direct labor, plus a predetermined rate for normal spoilage. At the end of the month, the work-in-process account is relieved by the standard cost per unit multiplied by the number of good units produced. This leaves a balance in the account which should be consistent with the uncompleted units still in process, but when compared to a physical inventory, there is a significant shortage of product in process, resulting in a write-down of inventory. When Hammon explained her problems to the production manager, he scoffed and said, “It’s your crazy standard cost system that is messed up.” The production manager says that Hammon’s cost system is poorly designed and does not track product costs accurately. Hammon is convinced there is nothing wrong with the design of the standard cost system. She knows that the inventory write- downs have no effect on the production manager’s compensation; however, she has heard that his bonus is partially affected by the actual amount of spoilage. She decides to further examine the provision for normal spoilage, as well as the actual spoilage reported. During the following month, she monitored the records of disposal truck traffic that left the plant at night. It would require only one truck nightly to dispose of the spoilage included in her standard cost. The records reflected an average of three disposal trucks leaving the plant each night. This unexplained traffic of disposal vehicles has caused her to be skeptical about the actual spoilage reported by the production manager.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
