Concept explainers
Rolertyme Company manufactures roller skates. With the exception of the rollers, all parts of the skates are produced internally. Neeta Booth, president of Rolertyme, has decided to make the rollers instead of buying them from external suppliers. The company needs 100,000 sets per year (currently it pays $1.90 per set of rollers).
The rollers can be produced using an available area within the plant. However, equipment for production of the rollers would need to be leased ($30,000 per year lease payment). Additionally, it would cost $0.50 per machine hour for power, oil, and other operating expenses. The equipment will provide 60,000 machine hours per year. Direct material costs will average $0.75 per set, and direct labor will average $0.25 per set. Since only one type of roller would be produced, no additional demands would be made on the setup activity. Other
Production of rollers would place the following demands on the overhead activities:
Producing the rollers also means that the purchase of outside rollers will cease. Thus, purchase orders associated with the outside acquisition of rollers will drop by 5,000. Similarly, the moves for the handling of incoming orders will decrease by 200. The company has not inspected the rollers purchased from outside suppliers.
Required:
- 1. Classify all resources associated with the production of rollers as flexible resources and committed resources. Label each committed resource as a short- or long-term commitment. How should we describe the cost behavior of these short- and long-term resource commitments? Explain.
- 2. Calculate the total annual resource spending (for all activities except for setups) that the company will incur after production of the rollers begins. Break this cost into fixed and variable activity costs. In calculating these figures, assume that the company will spend no more than necessary. What is the effect on resource spending caused by production of the rollers?
- 3. Refer to Requirement 2. For each activity, break down the cost of activity supplied into the cost of activity output and the cost of unused activity.

Cornerstones of Cost Management (Cornerstones Series)
- Andalus Furniture Company has two manufacturing plants, one at Aynor and another at Spartanburg. The cost in dollars of producing a kitchen chair at each of the two plants is given here. The cost of producing Q1 chairs at Aynor is: 75Q1+5Q12+100 and the cost of producing Q2 kitchen chairs at Spartanburg is: 25Q2+2.5Q22+150. Andalus needs to manufacture a total of 40 kitchen chairs to meet an order just received. How many chairs should be made at Aynor, and how many should be made at Spartanburg in order to minimize total production cost?arrow_forwardMossfort, Inc., has a division in Canada that makes long-lasting exterior wood stain. Mossfort has another U.S. division, the Retail Division, that operates a chain of home improvement stores. The Retail Division would like to buy the unique, long-lasting wood stain from the Canadian division, since this type of stain is not currently available. The Exterior Stain Division incurs manufacturing costs of 13.45 for one gallon of stain. If the Retail Division purchases the stain from the Canadian division, the shipping costs will be 1.40 per gallon, but sales commissions of 0.75 per gallon will be avoided with an internal transfer. The Retail Division plans to sell the stain for 32.80 per gallon. Normally, the Retail Division earns a gross margin of 35 percent above cost of goods sold. Required: 1. Which Section 482 method should be used to calculate the allowable transfer price? 2. Calculate the appropriate transfer price per gallon. (Round to the nearest cent.)arrow_forwardBoston Executive. Inc., produces executive limousines and currently manufactures the mini-bar inset at these costs: The company received an offer from Elite Mini-Bars to produce the insets for $2,100 per Unit and supply 1,000 mini-bars for the coming years estimated production. If the company accepts this offer and shuts down production of this part of the business, production workers and supervisors will be reassigned to other areas. Assume that for the short-term decision-making process demonstrated in this problem, the companys total labor costs (direct labor and supervisor salaries) will remain the same if the bar inserts are purchased. The specialized equipment cannot be used and has no market value. However, the space occupied by the mini bar production can be used by a different production group that will lease it for $55,000 per year. Should the company make or buy the mini-bar insert?arrow_forward
- Jonfran Company manufactures three different models of paper shredders including the waste container, which serves as the base. While the shredder heads are different for all three models, the waste container is the same. The number of waste containers that Jonfran will need during the following years is estimated as follows: The equipment used to manufacture the waste container must be replaced because it is broken and cannot be repaired. The new equipment would have a purchase price of 945,000 with terms of 2/10, n/30; the companys policy is to take all purchase discounts. The freight on the equipment would be 11,000, and installation costs would total 22,900. The equipment would be purchased in December 20x4 and placed into service on January 1, 20x5. It would have a five-year economic life and would be treated as three-year property under MACRS. This equipment is expected to have a salvage value of 12,000 at the end of its economic life in 20x9. The new equipment would be more efficient than the old equipment, resulting in a 25 percent reduction in both direct materials and variable overhead. The savings in direct materials would result in an additional one-time decrease in working capital requirements of 2,500, resulting from a reduction in direct material inventories. This working capital reduction would be recognized at the time of equipment acquisition. The old equipment is fully depreciated and is not included in the fixed overhead. The old equipment from the plant can be sold for a salvage amount of 1,500. Rather than replace the equipment, one of Jonfrans production managers has suggested that the waste containers be purchased. One supplier has quoted a price of 27 per container. This price is 8 less than Jonfrans current manufacturing cost, which is as follows: Jonfran uses a plantwide fixed overhead rate in its operations. If the waste containers are purchased outside, the salary and benefits of one supervisor, included in fixed overhead at 45,000, would be eliminated. There would be no other changes in the other cash and noncash items included in fixed overhead except depreciation on the new equipment. Jonfran is subject to a 40 percent tax rate. Management assumes that all cash flows occur at the end of the year and uses a 12 percent after-tax discount rate. Required: 1. Prepare a schedule of cash flows for the make alternative. Calculate the NPV of the make alternative. 2. Prepare a schedule of cash flows for the buy alternative. Calculate the NPV of the buy alternative. 3. Which should Jonfran domake or buy the containers? What qualitative factors should be considered?

The cost required to set up the production line to produce the 4-cylinder connecting rods is 2,000, and the cost required to set up the production line for the 6-cylinder connecting rods is 3,500. Manufacturing costs are 15 for each 4-cylinder connecting rod and 18 for each 6-cylinder connecting rod. There is no production on weekends, so on Friday the line is disassembled and cleaned. On Monday, the line must be set up to run whichever product will be produced that week. Once the line has been set up, the weekly production capacities are 6,000 6-cylinder connecting rods and 8,000 4-cylinder connecting rods. Let x4 = the number of 4-cylinder connecting rods produced next week x6 = the number of 6-cylinder connecting rods produced next week s4 = 1 if the production line is set up to produce the 4-cylinder connecting rods; 0 if otherwise s6 = 1 if the production line is set up to produce the 6-cylinder connecting rods; 0 if otherwise a. Using the decision variables x4 and s4, write a constraint that sets next weeks maximum production of the 4-cylinder connecting rods to either 0 or 8,000 units. b. Using the decision variables x6 and s6, write a constraint that sets next weeks maximum production of the 6-cylinder connecting rods to either 0 or 6,000 units. c. Write a constraint that requires that production be set up for exactly one of the two rods. d. Write the cost function to be minimized.arrow_forwardOat Treats manufactures various types of cereal bars featuring oats.

- Computador has a manufacturing plant in Des Moines that has the theoretical capability to produce 243,000 laptops per quarter but currently produces 91,125 units. The conversion cost per quarter is 7,290,000. There are 60,750 production hours available within the plant per quarter. In addition to the processing minutes per unit used, the production of the laptops uses 10 minutes of move time, 20 minutes of wait time, and 5 minutes of rework time. (All work is done by cell workers.) Required: 1. Compute the theoretical and actual velocities (per hour) and the theoretical and actual cycle times (minutes per unit produced). 2. Compute the ideal and actual amounts of conversion cost assigned per laptop. 3. Calculate MCE. How does MCE relate to the conversion cost per laptop?arrow_forwardVollmer Manufacturing makes three components for sale to refrigeration companies. The components are processed on two machines: a shaper and a grinder. The times (in minutes) required on each machine are as follows: The shaper is available for 120 hours, and the grinder for 110 hours. No more than 200 units of component 3 can be sold, but up to 1,000 units of each of the other components can be sold. In fact, the company already has orders for 600 units of component 1 that must be satisfied. The profit contributions for components 1, 2, and 3 are 8, 6, and 9, respectively. a.

- Ingles Corporation is a manufacturer of tables sold to schools, restaurants, hotels, and other institutions. The table tops are manufactured by Ingles, but the table legs are purchased from an outside supplier. The Assembly Department takes a manufactured table top and attaches the four purchased table legs. It takes 16 minutes of labor to assemble a table. The company follows a policy of producing enough tables to ensure that 40 percent of next months sales are in the finished goods inventory. Ingles also purchases sufficient materials to ensure that materials inventory is 60 percent of the following months scheduled production. Ingless sales budget in units for the next quarter is as follows: Ingless ending inventories in units for July 31 are as follows: Required: 1. Calculate the number of tables to be produced during August. 2. Disregarding your response to Requirement 1, assume the required production units for August and September are 2,100 and 1,900, respectively, and the July 31 materials inventory is 4,000 units. Compute the number of table legs to be purchased in August. 3. Assume that Ingles Corporation will produce 2,340 units in September. How many employees will be required for the Assembly Department in September? (Fractional employees are acceptable since employees can be hired on a part-time basis. Assume a 40-hour week and a 4-week month.) (CMA adapted)arrow_forwardOtero Fibers, Inc., specializes in the manufacture of synthetic fibers that the company uses in many products such as blankets, coats, and uniforms for police and firefighters. Otero has been in business since 1985 and has been profitable every year since 1993. The company uses a standard cost system and applies overhead on the basis of direct labor hours. Otero has recently received a request to bid on the manufacture of 800,000 blankets scheduled for delivery to several military bases. The bid must be stated at full cost per unit plus a return on full cost of no more than 10 percent after income taxes. Full cost has been defined as including all variable costs of manufacturing the product, a reasonable amount of fixed overhead, and reasonable incremental administrative costs associated with the manufacture and sale of the product. The contractor has indicated that bids in excess of 30 per blanket are not likely to be considered. In order to prepare the bid for the 800,000 blankets, Andrea Lightner, cost accountant, has gathered the following information about the costs associated with the production of the blankets. Direct machine costs consist of items such as special lubricants, replacement of needles used in stitching, and maintenance costs. These costs are not included in the normal overhead rates. Otero recently developed a new blanket fiber at a cost of 750,000. In an effort to recover this cost, Otero has instituted a policy of adding a 0.50 fee to the cost of each blanket using the new fiber. To date, the company has recovered 125,000. Lightner knows that this fee does not fit within the definition of full cost, as it is not a cost of manufacturing the product. Required: 1. Calculate the minimum price per blanket that Otero Fibers could bid without reducing the companys operating income. 2. Using the full-cost criteria and the maximum allowable return specified, calculate Otero Fibers bid price per blanket. 3. Without prejudice to your answer to Requirement 2, assume that the price per blanket that Otero Fibers calculated using the cost-plus criteria specified is greater than the maximum bid of 30 per blanket allowed. Discuss the factors that Otero Fibers should consider before deciding whether or not to submit a bid at the maximum acceptable price of 30 per blanket. (CMA adapted)arrow_forwardTaylor Company produces two industrial cleansers that use the same liquid chemical input: Pocolimpio and Maslimpio. Pocolimpio uses two quarts of the chemical for every unit produced, and Maslimpio uses five quarts. Currently, Taylor has 6,000 quarts of the material in inventory. All of the material is imported. For the coming year, Taylor plans to import 6,000 quarts to produce 1,000 units of Pocolimpio and 2,000 units of Maslimpio. The detail of each products unit contribution margin is as follows: Taylor Company has received word that the source of the material has been shut down by embargo. Consequently, the company will not be able to import the 6,000 quarts it planned to use in the coming years production. There is no other source of the material. Required: 1. Compute the total contribution margin that the company would earn if it could import the 6,000 quarts of the material. 2. Determine the optimal usage of the companys inventory of 6,000 quarts of the material. Compute the total contribution margin for the product mix that you recommend. 3. Assume that Pocolimpio uses three direct labor hours for every unit produced and that Maslimpio uses two hours. A total of 6,000 direct labor hours is available for the coming year. a. Formulate the linear programming problem faced by Taylor Company. To do so, you must derive mathematical expressions for the objective function and for the materials and labor constraints. b. Solve the linear programming problem using the graphical approach. c. Compute the total contribution margin produced by the optimal mix.arrow_forward
