18: CHAPTER SPOILAGE, REWORKED UNITS, AND SCRAP TRUE/FALSE 1. Reducing defects helps to reduce costs, but does not make the business more competitive. Answer: False Difficulty: 2 Reducing defects does make the business more competitive. 2. Objective: 1 Reworked goods are unacceptable units of production usually not capable of being repaired or converted into a salable product. Answer: False Difficulty: 2 Objective: 1 Reworked goods are unacceptable units of production that can be repaired into a salable product. 3. The value of scrap material can have either a high or low sales value relative to the product with which it is associated. Answer: False Difficulty: 2 Scrap material by definition has a low sales value. Objective: 1 4. Normal spoilage adds to the cost of the job to which it is attributed in a job order costing system. Answer: True Difficulty: 2 Objective: 2 5. When calculating normal spoilage rates, the base should be actual units started in production. Answer: False Difficulty: 2 The base should be good units started into production. Objective: 2 6. Abnormal spoilage is spoilage that should arise under efficient operating conditions. Answer: False Difficulty: 2 Objective: Abnormal spoilage should not arise under efficient operating conditions. 2 7. A company whose goal is zero defects would usually treat all spoilage as abnormal. Answer: True Difficulty: 2 Objective: 2 8. Counting spoiled units as part of output units in a process-costing system usually results in a higher cost per unit. Answer: False Difficulty: 3 Objective: Counting spoiled units usually results in a lower cost per unit. Chapter 18 Page 1 3 9. Costs in beginning inventory are pooled with costs in the current period when determining the costs of good units under the weighted-average method of process costing. Answer: True Difficulty: 2 Objective: 3 10. Under the weighted-average method, the costs of normal spoilage are added to the costs of their related good units. Hence, the cost per good unit completed and transferred out equals the total costs transferred out divided by the number of good units produced. Answer: True Difficulty: 3 Objective: 3 11. Under the FIFO method, all spoilage costs are assumed to be related to units completed during this period using the unit costs of the current period. Answer: True Difficulty: 3 Objective: 4 12. When spoiled goods have a disposal value, the net cost of spoilage is computed by adding the disposal value to the costs of the spoiled goods accumulated to the inspection point. Answer: False Difficulty: 2 Objective: 4 The net cost of spoilage is computed by subtracting the disposal value from the costs of the spoiled goods accumulated to the inspection point. 13. Normal spoilage costs are usually deducted from the costs of good units. Answer: False Difficulty: 2 Objective: Normal spoilage is usually added to the cost of the good units. 5 14. Costs of abnormal spoilage are separately accounted for as losses of the period. Answer: True Difficulty: 2 Objective: 5 15. In job costing, costs of abnormal spoilage are not considered as inventoriable costs and are therefore written off as costs of the period in which detection occurs. Answer: True Difficulty: 3 Objective: 6 16. In both job costing and process costing, normal spoilage attributable to a specific job is assigned to that job. Answer: False Difficulty: 3 Objective: In process costing, spoilage costs are not assigned to that job. 6 Chapter 18 Page 2 17. When rework is normal and not attributable to any specific job, the costs of rework are charged to manufacturing overhead, and spread through overhead allocation over all jobs. Answer: True Difficulty: 3 Objective: 7 18. Scrap is usually divided between normal and abnormal scrap. Answer: False There is no abnormal scrap. Difficulty: 2 Objective: 8 19. If scrap is returned to the company's storeroom and thus inventoried, it should not have any value in the accounting records. Answer: False Difficulty: 3 Objective: 8 The scrap will be inventoried. It might not have a value in dollars but it will have a physical quantity value. 20.

Beginning work in process (5% complete) Yes No No Answer: d Difficulty: 3 Objective: A Chapter 18 Page 17 EXERCISES AND PROBLEMS 71. Distinguish among spoilage, reworked units, and scrap. Give an example of each. Answer: Spoilage refers to unacceptable units of production that are discarded or are sold for reduced prices. Both partially completed or fully completed units of output can be spoiled. Examples are defective clothes sold as seconds. Reworked units are unacceptable units of production that are subsequently repaired and sold as acceptable finished goods. Defective units of product (such as pagers, computer disk drives, computers, and telephones) detected during production or immediately after production but before units are shipped to customers, can sometimes be reworked and sold as good products. Scrap is material left over when making a product. It has low sales value compared with the sales value of the product. Examples are shavings and short lengths from woodworking operations and edges left over from plastic molding operations.

What are the objectives in accounting for spoilage? Answer: The key objectives in accounting for spoilage are determining the magnitude of the costs of the spoilage and distinguishing between the costs of normal and abnormal spoilage. In order to effectively manage a company (or a division of a business), a manager needs information concerning how his business is performing. Spoilage is a cost, which should be controlled and minimized. The dimensions of the cost must be known (the dollar amount of the spoilage). The accounting system must be capable of determining the dollar amount of the spoilage costs while distinguishing between normal and abnormal spoilage.

Busy Hands Craft Company is a small manufacturing company that specializes in arts and crafts items. It recently bought an old textile mill that it has refurbished to manufacture and dye special cloth to be sold in its craft shops. However, it discovered something new for its accounting system. The company never before had finished goods that did not meet standard, leftover materials from processing runs, or unacceptable outputs. Required: As the business consultant for the company, explain how it can handle the items mentioned. Include any potential problems with the accounting procedures. Answer: First, an explanation of each item is needed. 1. 2. 3. Rework units are those units that are defective but can be reworked and sold as acceptable finished goods. Scrap is leftover material that may have a minimal sales value. Scrap may be either sold, disposed of, or reused in another job or processing run. Spoilage is the production outputs that cannot be reworked. These units are discarded or sold for minimal value. The potential problem with these areas is that they may be treated differently by the accounting system. The company should establish an acceptable and consistent method of handling each area. A consistent policy also aids the managers who are being evaluated by their department's efforts. Difficulty: 82. 2 Objective: 1 You are the chief financial officer of a lumber mill, and are becoming quite concerned about the spoilage, scrap, and reworked items associated with your production processes. Your firm produces mainly products for the building industry. Required: Discuss the problems associated with these items, and the methods your company can use to reduce spoilage, scrap, and reworked items. Answer: The problems associated with these items include: 1. Your company pays for the total raw material not just the portion converted into a salable product. 2. The cost of disposing of these unsalable or unused items, both the disposal costs and the costs and problems associated with finding a landfill site or other disposal site. 3. These disposed of or unused items can create an eyesore, and attract the wrath of the environmentalists. 4. Developing high-value added products that can be produced from these various items. Chapter 18 Page 29 82. (continued) The methods your company can use to reduce these items include: 1. Calculating the costs of these problems. An accurate assessment of the total costs should certainly provide an incentive to your firm to investigate possible actions. 2. Exploring methods of redesigning the production process to minimize these costs. 3. Investing in more sophisticated capital equipment that can be designed to reduce these costs. Difficulty: 3 Objective: 1 83. Harriet has been reviewing the accounting system for her company and is very concerned about the accounting for spoilage. It appears that spoilage is accounted for only at the end of the processing cycle. While this concept is acceptable in general, Harriet believes that a better method can be found to properly account for the spoilage when it occurs. She believes that there must be something better than the weightedaverage method of accounting for spoilage. She would like the company to use a method that provides closer tracking of the spoilage with the accounting for the spoilage. Required: Discuss the problems Harriet is having with the accounting system. Answer: The main problem Harriet has is that she does not understand the accounting system. The use of weighted-average or FIFO is not for addressing the problems of spoilage tracking. While the methods do differ slightly in the tracking of costs, FIFO keeps beginning inventories separate, and the point of accounting for spoilage is not affected by the accounting method. If the company can account for spoilage at different stages of completion, these stages can be converted into percentage of completion points, and the spoilage can be accounted for as the process completes each stage. Difficulty: 3 Objective: 2 Chapter 18 Page 30 84. Shazam Machines produces numerous types of money change machines. All machines are made in the same production department and many use exactly the same processes. Because customers have such different demands for the machine characteristics, the company uses a job-costing system. Unfortunately, some of the production managers have been upset for the last few months when their jobs were charged with the spoilage that occurred over an entire processing run of several types of machines. Some of the best managers have even threatened to quit unless the accounting system is changed. Required: What recommendations can you suggest to improve the accounting for spoilage? Answer: Since the manufacturing process uses similar workstations for the products, it may be best to let the spoilage be considered a manufacturing problem rather than a job problem. With this assumption, the spoilage will be spread over the entire production process with each job being charged an appropriate amount of spoilage, thereby relieving some jobs of bearing the entire burden of spoilage just because they were being worked on when the machines or process malfunctioned. Difficulty: 2 Objective: 6 85. For each of the following (actual real-world examples) develop products that can be sold from the listed scrap. a. b. c. The Federal Reserve Banks destroy old money. Burning this money is usually forbidden under the environmental laws of most municipalities. A manufacturer of cotton undergarments for female prisoners has much cotton left over. The manufacturer is located in a very rural area of Alabama. A hog renderer that has hog bristles as a result of the slaughtering process. Answer: a. The Federal Reserve Banks bag up the shredded money and sell it in gift shops. This is a very efficient use of the scrap. The purchasers pay a price in excess of what the Federal Reserve would receive from any other source. Other uses might include selling for use as packaging materials. b. The above manufacturer sells the scrap for use in the cleaning of guns. Other uses would include similar cleaning uses or dyeing the cloth and selling it for ornaments. The hog bristles can be used in shaving equipment and for bristle brushes. 2 Objective: 8 c. Difficulty: Chapter 18 Page 31
