Chapter Special Production Issues: Lost Units and Accretion Questions An accepted quality level (AQL) is the proportion of total units to be produced in a process without defects as preestablished by an appropriate minimum that is determined by management Alternatively, an AQL can be stated as the proportion of total units to be produced in a process that can be defective as preestablished by an appropriate maximum determined by management When the AQL is set at 100 percent for good production, then the acceptable defect level is set at zero In this case, the AQL is set at a level of 100 percent and this is the same as a zerodefects tolerance level Shrinkage refers to loss of inputs because of natural processes such as evaporation or oxidation Spoiled units cannot be economically reworked to bring them up to standard Defective units can e economically reworked because the incremental revenue exceeds the incremental cost of the rework Both spoiled and defective units not meet quality specifications upon inspection A tolerated loss level may be set because losses are inherent in the production process (e.g., shrinkage) or there are known defects in materials used or in production processes For example, management may know that a particular production process performs within tolerances only 99.5 percent of the time Accordingly, management may allow for defects out of every 1,000 units produced Although management could invest in technology that would reduce the level of defects, the new technology may be too costly relative to the existing level of defects With this cost/benefit analysis, management has concluded that a certain level of defects is preferred to no defects 165 166 CHAPTER Special Production Issues: Lost Units and Accretion Examples of defective units include the following: a car that has been painted the wrong color; the delivery of personal possessions to the wrong address by a moving company; an incorrectly mounted transmission in a new automobile; a piece of lumber that has been cut too long for its intended application; and a fishing reel that has been assembled without a required bearing Examples of spoiled products/services include the following: a tire that that has treads which are irregularly positioned on the tire (e.g., treads that would not be parallel to the road); a tax return prepared by an accounting firm that was audited by the IRS and determined to have large errors; a cake that has been cut into pieces that are too small; a tree that died because it was trimmed so severely by a landscaping service; loss of a patient’s sight caused by a surgeon’s error during an operation Normal loss refers to an expected reduction in production quantity based on the production technology and production practices of the company Abnormal loss refers to a quantity of loss above the normal loss quantity Normal loss creates an expected cost of production so the cost of such a loss is inventoriable; abnormal spoilage cost is not expected, and, thus, it is not inventoriable Abnormal losses would be more likely to be preventable than normal losses because abnormal losses are less likely to be caused by factors that are inherent in the materials or production methods For example, a known amount of material loss (waste) is to be expected if lower quality materials are utilized However, any loss beyond the expected amount would likely be caused by other factors that are subject to management control, e.g., production errors A continuous loss is one that occurs (more or less) uniformly throughout the production process A discrete loss is one that occurs at a specific stage or in a specific production process A discrete loss occurs at a specific point in the production process For accounting purposes, discrete loss is assumed to occur immediately prior to inspection In reality, the loss could have occurred anywhere before the inspection point and, thus, the lost units should have had no additional conversion (and/or, possibly, materials) added to them It is impossible to have continuous monitoring for losses in most production processes, so conversion costs are incurred until inspection and assigned to all units that have passed the inspection point (even though some units that have not reached the inspection point could also be lost) CHAPTER 167 Special Production Issues: Lost Units and Accretion Any time a decline in the value of an asset occurs that is unexpected, it is considered a loss of the period Abnormal losses are unplanned for and are in excess of normal losses Therefore, the cost associated with them should not be considered a product cost and should not be allocated to good production The units themselves have no value and cannot be considered assets, so their costs are expired and belong on the income statement The cost is removed by debiting a loss account (such as "Loss from Abnormal Spoilage") and crediting Work in Process Inventory 10 The method of neglect requires no specific computations regarding spoiled units; all costs are assigned to good units The cost of spoiled units that have been found at an inspection point will be assigned to all units that have passed the inspection point Thus, the method of neglect assigns spoilage costs by simply ignoring (neglecting) the spoiled units The method of neglect is appropriate if loss is considered to be incurred continuously and is considered normal 11 The method of neglect raises the cost per equivalent unit because no costs are assigned to the spoiled units Therefore, good units bear all costs, including the costs of producing the spoiled units 12 If spoilage is incurred for all (or most) jobs in a job order costing system, the estimate of overhead used in setting the predetermined overhead rate should include an amount for the net cost of spoilage This will allow the cost of normal, general spoilage to be spread over all jobs produced If spoilage is related to a single job, the cost of that spoilage should be assigned to the job that gave rise to it If any abnormal spoilage is incurred in a job order system, its cost should be assigned to the period as a loss 13 Accretion is an increase in the number of units or the volume of a product that occurs through the addition of materials (e.g., water or other fluids) or through processing (e.g., heat causing expansion) Although the total cost of the predecessor department is unaffected, the cost per unit calculated by the predecessor department would decline in the successor department because of the increase in units 14 The cost per unit might have declined in the second department because of an increase in the number of units caused by the addition of materials or the expansion of the units transferred in If the company manufactures bread, the rising of the dough would cause an increase in the volume of dough transferred in from the Mixing Department 168 15 CHAPTER Special Production Issues: Lost Units and Accretion If the defects are considered normal, the treatment of rework costs depends on whether an actual or a normal cost system is in effect If an actual cost system is used, the rework costs will be added to the component costs of the period and be allocated to all units completed In a normal cost system, the rework costs will have been estimated and included in the development of the overhead application rate; actual rework costs would be assigned to Manufacturing Overhead If the defects are abnormal, the costs of production and rework costs for the defective units should be accumulated and assigned to a loss account 16 The important managerial concern is to control spoilage and defective work rather than to account for it Measuring its cost is the first step in controlling spoilage/defects Using the method of neglect or otherwise spreading the cost of the lost units to good production minimizes the degree of control that can be exerted by management 17 Certain fluctuations occur in any production process Statistical process controls can be used to determine if fluctuations in a process are within normal and tolerable limits, or exceed tolerable limits In short, the SPC methods can be used to determine whether a process is in control SPC charts can also be used as indicators of the points at which the process is out of control and thus helps managers understand why fluctuations occur in a process so that actions can be taken to reduce such fluctuations 18 Each student will have a different answer No solution

per year by purchasing the regulator The amount he would pay would be based on the expected life of the regulator and (in a discounted cash flow framework) on the cost of capital of the firm In addition to these factors, Alfred would want to consider how long the company intends to keep the machinery that currently prints the packing boxes, the costs of operating and installing the regulator, the costs of training personnel to operate it and the utility and maintenance costs for the machine (if different from those currently experienced) 20 b Good boxes = 600 – 50 = 550 Spoilage cost per setup = 50 × $8.50 = $425 Increase in cost = $425 ÷ 550 = $0.77 (rounded) c To obtain the correct 20 boxes in each batch, WEBOXALL must first produce the 50 misprinted boxes Total Per Box Costs of spoilage = 12 × 50 × $8.50 = $5,100 $21.25 Cost of regulator 4,300 17.92 Net savings in cost $ 800 $ 3.33 Yes, Springtime Corporation would be willing to purchase the regulator because it would result in substantial cost savings The cost of the regulator would be recouped in less than one year’s volume of purchases However, an alternative for Springtime would be to purchase all of its boxes in a single transaction rather than in 12 different batches In such a case, the total spoilage cost incurred would only be $425 (50 boxes × $8.50) d The spoilage cost-per-box figures differ substantially because of the number of units produced in the batches In part (b), the batch costs of spoilage were spread over 550 good units; in part (c), the costs of spoilage for each batch were spread over only 20 units 21 a 10,000 + 60,000 = 70,000 units b 60,000 × 0.05 = 3,000 units c Abnormal loss = Total units – (Completed Units + EI units + Normal loss) = 70,000 - (58,200 + 8,000 +

units As such, it is not an extra cost but thought to be inherent in producing good units Normal spoilage may occur because of material or labor quality, machine malfunctions, or human error Management should cost=benefit studies to determine if it is economically sensible to reduce spoilage Three questions should be addressed: (1) What does the spoilage actually cost? (2) Why does it occur? (3) How can it be controlled?
