Question: Weighted-average method, inspection at 80% completion. (A. Atkinson) The Horsheim Company is a furniture manufacturer with two departments: molding and finishing. The company uses the weighted-average method of process costing. In August, the following data were recorded for the finishing department:
Conversion costs are added evenly during the process. Direct material costs are added when production is 90% complete. The inspection point is at the 80% stage of production. Normal spoilage is 10% of all good units that pass inspection. Spoiled units are disposed of at zero net disposal value.
1. For August, summarize total costs to account for and assign these costs to units completed and transferred out (including normal spoilage), to abnormal spoilage, and to units in ending work in process.
2. What are the managerial issues involved in determining the percentage of spoilage considered normal? How would your answer to requirement 1 differ if all spoilage were treated as normal?
