Kagle design engineers are in the process of developing a new green product, one that will significantly reduce impact on the environment and yet still provide the desired customer functionality. Currently, two designs are being considered. The manager of Kagle has told the engineers that the cost for the new product cannot exceed 550 per unit (target cost). In the past, the Cost Accounting Department has given estimated costs using a unit-based system. At the request of the Engineering Department, Cost Accounting is providing both unit-and activity-based accounting information (made possible by a recent pilot study producing the activity-based data). Unit-based system: Variable conversion activity rate: 100 per direct labor hour Material usage rate: 20 per part ABC system: Labor usage: 15 per direct labor hour Material usage (direct materials): 20 per part Machining: 75 per machine hour Purchasing activity: 150 per purchase order Setup activity: 3,000 per setup hour Warranty activity: 500 per returned unit (usually requires extensive rework) Customer repair cost: 25 per repair hour (average) Required: 1. Select the lower-cost design using unit-based costing. Are logistical and post-purchase activities considered in this analysis? 2. Select the lower-cost design using ABC analysis. Explain why the analysis differs from the unit-based analysis. 3. What if the post-purchase cost was an environmental contaminant and amounted to 10 per unit for Design A and 40 per unit for Design B? Assume that the environmental cost is borne by society. Now which is the better design?
Larsen, Inc., produces two types of electronic parts and has provided the following data: There are four activities: machining, setting up, testing, and purchasing. Required: 1. Calculate the activity consumption ratios for each product. 2. Calculate the consumption ratios for the plantwide rate (direct labor hours). When compared with the activity ratios, what can you say about the relative accuracy of a plantwide rate? Which product is undercosted? 3. What if the machine hours were used for the plantwide rate? Would this remove the cost distortion of a plantwide rate?
Silven Company has identified the following overhead activities, costs, and activity drivers for the coming year: Silven produces two models of cell phones with the following expected activity demands: 1. Determine the total overhead assigned to each product using the four activity drivers. 2. Determine the total overhead assigned to each model using the two most expensive activities. The costs of the two relatively inexpensive activities are allocated to the two expensive activities in proportion to their costs. 3. Using ABC as the benchmark, calculate the percentage error and comment on the accuracy of the reduced system. Explain why this approach may be desirable.

Nizam Company produces speaker cabinets. Recently, Nizam switched from a traditional departmental assembly line system to a manufacturing cell in order to produce the cabinets. Suppose that the cabinet manufacturing cell is the cost object. Assume that all or a portion of the following costs must be assigned to the cell: a. Depreciation on electric saws, sanders, and drills used to produce the cabinets b. Power to heat and cool the plant in which the cell is located c. Salary of cell supervisor d. Wood used to produce the cabinet housings e. Maintenance for the cells equipment (provided by the maintenance department) f. Labor used to cut the wood and to assemble the cabinets g. Replacement sanding belts h. Cost of janitorial services for the plant i. Ordering costs for materials used in production j. The salary of the industrial engineer (she spends about 20 percent of her time on work for the cell) k. Cost of maintaining plant and grounds l. Cost of plants personnel office m. Depreciation on the plant n. Plant receptionists salary and benefits Required: Identify which cost assignment method would likely be used to assign the costs of each of the preceding activities to the cabinet manufacturing cell: direct tracing, driver tracing, or allocation. When driver tracing is selected, identify a potential activity driver that could be used for the tracing.
Hales Company produces a product that requires two processes. In the first process, a subassembly is produced (subassembly A). In the second process, this subassembly and a subassembly purchased from outside the company (subassembly B) are assembled to produce the final product. For simplicity, assume that the assembly of one final unit takes the same time as the production of subassembly A. Subassembly A is placed in a container and sent to an area called the subassembly stores (SB stores) area. A production Kanban is attached to this container. A second container, also with one subassembly, is located near the assembly line (called the withdrawal store). This container has attached to it a withdrawal Kanban. Required: 1. Explain how withdrawal and production Kanban cards are used to control the work flow between the two processes. How does this approach minimize inventories? 2. Explain how vendor Kanban cards can be used to control the flow of the purchased subassembly. What implications does this have for supplier relationships? What role, if any, do continuous replenishment and EDI play in this process?
Southward Company has implemented a JIT flexible manufacturing system. John Richins, controller of the company, has decided to reduce the accounting requirements given the expectation of lower inventories. For one thing, he has decided to treat direct labor cost as a part of overhead and to discontinue the detailed direct labor accounting of the past. The company has created two manufacturing cells, each capable of producing a family of products: the radiator cell and the water pump cell. The output of both cells is sold to a sister division and to customers who use the radiators and water pumps for repair activity. Product-level overhead costs outside the cells are assigned to each cell using appropriate drivers. Facility-level costs are allocated to each cell on the basis of square footage. The budgeted direct labor and overhead costs are as follows: The predetermined conversion cost rate is based on available production hours in each cell. The radiator cell has 45,000 hours available for production, and the water pump cell has 27,000 hours. Conversion costs are applied to the units produced by multiplying the conversion rate by the actual time required to produce the units. The radiator cell produced 81,000 units, taking 0.5 hour to produce one unit of product (on average). The water pump cell produced 90,000 units, taking 0.25 hour to produce one unit of product (on average). Other actual results for the year are as follows: All units produced were sold. Any conversion cost variance is closed to Cost of Goods Sold. Required: 1. Calculate the predetermined conversion cost rates for each cell. 2. Prepare journal entries using backflush accounting. Assume two trigger points, with completion of goods as the second trigger point. 3. Repeat Requirement 2, assuming that the second trigger point is the sale of the goods. 4. Explain why there is no need to have a work-in-process inventory account. 5. Two variants of backflush costing were presented in which each used two trigger points, with the second trigger point differing. Suppose that the only trigger point for recognizing manufacturing costs occurs when the goods are sold. How would the entries be listed here? When would this backflush variant be considered appropriate?
Salem Electronics currently produces two products: a programmable calculator and a tape recorder. A recent marketing study indicated that consumers would react favorably to a radio with the Salem brand name. Owner Kenneth Booth was interested in the possibility. Before any commitment was made, however, Kenneth wanted to know what the incremental fixed costs would be and how many radios must be sold to cover these costs. In response, Betty Johnson, the marketing manager, gathered data for the current products to help in projecting overhead costs for the new product. The overhead costs based on 30,000 direct labor hours follow. (The high-low method using direct labor hours as the independent variable was used to determine the fixed and variable costs.) All depreciation. The following activity data were also gathered: Betty was told that a plantwide overhead rate was used to assign overhead costs based on direct labor hours. She was also informed by engineering that if 20,000 radios were produced and sold (her projection based on her marketing study), they would have the same activity data as the recorders (use the same direct labor hours, machine hours, setups, and so on). Engineering also provided the following additional estimates for the proposed product line: Upon receiving these estimates, Betty did some quick calculations and became quite excited. With a selling price of 26 and just 18,000 of additional fixed costs, only 4,500 units had to be sold to break even. Since Betty was confident that 20,000 units could be sold, she was prepared to strongly recommend the new product line. Required: 1. Reproduce Bettys break-even calculation using conventional cost assignments. How much additional profit would be expected under this scenario, assuming that 20,000 radios are sold? 2. Use an activity-based costing approach, and calculate the break-even point and the incremental profit that would be earned on sales of 20,000 units. 3. Explain why the CVP analysis done in Requirement 2 is more accurate than the analysis done in Requirement 1. What recommendation would you make?
Life Force Fitness, Inc., assembles and sells treadmills. Activity-based product information for each treadmill is as follows: All of the activity costs are related to labor. Management must remove 2.00 of activity cost from the product in order to remain competitive. Rework involves disassembling and repairing a unit that fails testing. Not all units require rework, but the average is 0.40 hour per unit. Presently, the testing is done on the completed assembly; but much of the rework has been related to motors, which can be tested independently prior to adding the motor to the treadmill during final assembly. Thus, motor issues can be diagnosed and solved without having to disassemble the complete treadmill. This change will reduce the average rework per unit by one-quarter. a.Determine the new activity cost per unit under the rework improvement scenario. b.If management had the choice of doing the rework improvement in (a) or cutting the moving activity in half by improving the product flow, which decision should be implemented? Why?
Fisico Company produces exercise bikes. One of its plants produces two versions: a standard model and a deluxe model. The deluxe model has a wider and sturdier base and a variety of electronic gadgets to help the exerciser monitor heartbeat, calories burned, distance traveled, etc. At the beginning of the year, the following data were prepared for this plant: Additionally, the following overhead activity costs are reported: Required: 1. Calculate the cost per unit for each product using direct labor hours to assign all overhead costs. 2. Calculate activity rates and determine the overhead cost per unit. Compare these costs with those calculated using the unit-based method. Which cost is the most accurate? Explain.
