Process Costing versus Alternative Costing Methods, Impact on Resource Allocation Decision
Golding Manufacturing, a division of Farnsworth Sporting Inc., produces two different models of bows and eight models of knives. The bow-manufacturing process involves the production of two major subassemblies: the limbs and the handles. The limbs pass through four sequential processes before reaching final assembly: layup, molding, fabricating, and finishing. In the layup department, limbs are created by laminating layers of wood. In the molding department, the limbs are heat-treated, under pressure, to form strong resilient limbs. In the fabricating department, any protruding glue or other processing residue is removed. Finally, in the finishing department, the limbs are cleaned with acetone, dried, and sprayed with the final finishes.
The handles pass through two processes before reaching final assembly: pattern and finishing. In the pattern department, blocks of wood are fed into a machine that is set to shape the handles. Different patterns are possible, depending on the machine's setting. After coming out of the machine, the handles are cleaned and smoothed. They then pass to the finishing department, where they are sprayed with the final finishes. In final assembly, the limbs and handles are assembled into different models using purchased parts such as pulley assemblies, weight-adjustment bolts, side plates, and string.
Golding, since its inception, has been using process costing to assign product costs. A predetermined overhead rate is used based on direct labor dollars (80% of direct labor dollars). Recently, Golding has hired a new controller, Karen Jenkins. After reviewing the product-costing procedures, Karen requested a meeting with the divisional manager, Aaron Suhr. The following is a transcript of their conversation:
Karen : Aaron, I have some concerns about our cost accounting system. We make two different models of bows and are treating them as if they were the same product. Now I know that the only real difference between the models is the handle. The processing of the handles is the same, but the handles differ significantly in the amount and quality of wood used. Our current costing does not reflect this difference in material input.
Aaron : Your predecessor is responsible. He believed that tracking the difference in material cost wasn't worth the effort. He simply didn't believe that it would make much difference in the unit cost of either model.
Karen : Well, he may have been right, but I have my doubts. If there is a significant difference, it could affect our views of which model is more important to the company. The additional bookkeeping isn't very stringent. All we have to worry about is the pattern department. The other departments fit what I view as a process-costing pattern.
Aaron : Why don't you look into it? If there is a significant difference, go ahead and adjust the costing system.
After the meeting, Karen decided to collect cost data on the two models: the Deluxe model and the Econo model. She decided to track the costs for one week. At the end of the week, she had collected the following data from the pattern department:
a. There were a total of 2,500 bows completed: 1,000 Deluxe models and 1,500 Econo models.
b. There was no BWIP; however, there were 300 units in EWIP: 200 Deluxe and 100 Econo models. Both models were 80% complete with respect to conversion costs and 100% complete with respect to materials.
c. The pattern department experienced the following costs:
d. On an experimental basis, the requisition forms for materials were modified to identify the dollar value of the materials used by the Econo and Deluxe models:
