Best Furniture manufactures plastic pool-side furniture in a continuous process. The company pours molten plastic into molds and then cools the plastic. Materials are added at the beginning of the process, and conversion is considered uniform through the period. Occasionally, the plastic does not completely fill a mold because of air pockets, and the chair is then considered spoilage. Normal spoilage is 6% of the good units that pass inspection. The following information pertains to April 2014 Beginning inventory 1,400 units (100% complete for materials; 20% complete for conversion costs) Units started 12,000 units Unites in ending work in 1,100 units (100% complete for materials; 70% complete for process conversion costs) Best Furniture had 1,000 spoiled units in April 2014.
