Weighted-Average, Normal vs Abnormal Spoilage
Hebert Industries uses a weighted average process costing system. Management has specified that the normal loss from shrinkage cannot exceed 3 percent of the units started in a period.
All raw material is added at the start of the production process. Spoilage is determined upon inspection at the end of the production process. March processing information follows.
Beginning WIP inventory (30% complete as to conversion) 20,000 units
Started during March 120,000 units
Completed during March 116,400 units
Ending WIP inventory (20% complete as to conversion) 16,000 units
