Chapter 18, Problem 18.39P

Physical units, inspection at various levels of completion, weighted-average process costing. SunEnergy produces solar panels. A key step in the conversion of raw silicon to a completed solar panel occurs in the assembly department, where lightweight photovoltaic cells are assembled into modules and connected on a frame. In this department, materials are added at the beginning of the process and conversion takes place uniformly.

At the start of November 2017, SunEnergy’s assembly department had 2,400 panels in beginning work in process, which were 100% complete for materials and 40% complete for conversion costs. An additional 12,000 units were started in the department in November, and 3,600 units remain in work in process at the end of the month. These unfinished units are 100% complete for materials and 70% complete for conversion costs.

The assembly department had 1,800 spoiled units in November. Because of the difficulty of keeping moisture out of the modules and sealing the photovoltaic cells between layers of glass, normal spoilage is approximately 12% of good units. The department’s costs for the month of November are as follows:

  Beginning WIP Costs Incurred During Period
Direct materials costs $ 76,800 $ 240,000
Conversion costs 123,000 1,200,000
  1. 1. Using the format on page 728, compute the normal and abnormal spoilage in units for November, assuming the inspection point is at (a) the 30% stage of completion, (b) the 60% stage of completion, and (c) the 100% stage of completion.

Required

  1. 2. Refer to your answer in requirement 1. Why are there different amounts of normal and abnormal spoilage at different inspection points?
  2. 3. Now assume that the assembly department inspects at the 60% stage of completion. Using the weighted-average method, calculate the cost of units transferred out, the cost of abnormal spoilage, and the cost of ending inventory for the assembly department in November.

Chem Corp. manufactures bottles of hand sanitizer. The liquid sanitizer is manufactured in the Manufacturing Department. When manufacturing is complete, the liquid sanitizer is then transferred to the Packaging Department where the liquid is bottled, labeled, and packed into cases for shipping. In the Packaging Department, direct materials are added when the process is 60% complete; conversion costs are added evenly throughout. For the current period the Manufacturing Department transferred 200,000 liquid units to the Packaging Department. Beginning work in process in the Packaging Department included 50,000 units that were 40% complete as to conversion. Ending inventory totaled 20,000 units that were 20% complete as to conversion in the Packaging Department. Calculate the Packaging Department’s equivalent units for transferred-in, direct materials and conversion costs (respectively) using the FIFO method of process costing
Rosenthal Company manufactures bowling balls through two processes: Molding and Packaging. In the Molding Department, the urethane, rubber, plastics, and other materials are molded into bowling balls. In the Packaging Department, the balls are placed in cartons and sent to the finished goods warehouse. All materials are entered at the beginning of each process. Labor and manufacturing overhead are incurred uniformly throughout each process. Production and cost data for the Molding Department during June 2017 are presented below. Production Data   June Beginning work in process units   0   Units started into production   27,720   Ending work in process units   2,520   Percent complete—ending inventory   40 % Cost Data     Materials   $249,480 Labor   67,536 Overhead   142,128     Total   $459,144     Prepare a schedule showing physical units of production.
