Alpha Manufacturers Ltd manufactures tables in its Processing Department. Direct materials are included at the inception of the production cycle and must be bundled in single kits for each unit. Conversion costs are incurred evenly throughout the production process. Inspection takes place at the end of the production process. After inspection, some units are usually found to be spoiled due to non-detectable material defects. Such spoiled units generally constitute 4% of the good units completed and transferred out during the process. Alpha uses the First-In-First-Out (FIFO) method of process costing.
