CASE 4-20 Second Department-Weighted-Average Method [LO2, LO3, L04] Durall Company manufactures a plastic gasket that is used in automobile engines. The gaskets go through three processing departments: Mixing, Forming, and Stamping. The company's accountant (who is very inexperienced) has prepared a summary of production and costs for the Forming Department for October as follows: - Lonsists or cost transierred in, \$8,8$10,200 After mulling over the data above, Durall's president commented, "I can't understand what's happening here. Despite a concentrated effort at cost reduction, our unit cost actually went up in the Forming Department last month. With that kind of performance, year-end bonuses are out of the question for the people in that department." The company uses the weighted-average method in its process costing. Required: 1. Prepare a report for the Forming Department for October showing how much cost should have been assigned to the units completed and transferred to the Stamping Department and to the ending work in process inventory. 2. Explain to the president why the unit cost appearing on the report prepared by the accountant is so high
