Single plantwide and multiple production department factory overhead rate methods and product cost distortion
The management of Firebolt Industries Inc. manufactures gasoline and diesel engines through two production departments, Fabrication and Assembly. Management needs accurate product cost information in order to guide product strategy. Presently, the company uses a single plantwide factory overhead rate for allocating factory overhead to the two products. However, management is considering the multiple production department factory overhead rate method. The following factory overhead was budgeted for Firebolt:
Fabrication Department factory overhead | $550,000 |
Assembly Department factory overhead | 250,000 |
Total | $800,000 |
Direct labor hours were estimated as follows:
Fabrication Department | 5,000 hours |
Assembly Department | 5,000 |
Total | 10,000 hours |
In addition, the direct labor hours(dlh) used to produce a unit of each product in each department were determined from engineering records, as follows:
Production Departments | Gasoline Engine | Diesel Engine |
Fabrication Department | 3.0 dlh | 2.0 dlh |
Assembly Department | 2.0 | 3.0 |
Direct labor hours per unit | 5.0 dlh | 5.0 dlh |
A. Determine the per-unit factory- overhead allocated to the gasoline and diesel engines under the single plantwide factory overhead rate method, using direct labor hours as the activity base.
B. Determine the per-unit factor)' overhead allocated to the gasoline and diesel engines under the multiple production department factory overhead rate method, using direct labor hours as the activity base for each department.
C. Recommend to management a product costing approach, based on your analyses in (A) and (B). Support your recommendation.

- Young Company is beginning operations and is considering three alternatives to allocate manufacturing overhead to individual units produced. Young can use a plantwide rate, departmental rates, or activity-based costing. Young will produce many types of products in its single plant, and not all products will be processed through all departments. In which one of the following independent situations would reported net income for the first year be the same regardless of which overhead allocation method had been selected? a. All production costs approach those costs that were budgeted. b. The sales mix does not vary from the mix that was budgeted. c. All manufacturing overhead is a fixed cost. d. All ending inventory balances are zero.arrow_forwardPelder Products Company manufactures two types of engineering diagnostic equipment used in construction. The two products are based upon different technologies, X-ray and ultrasound, but are manufactured in the same factory. Pelder has computed the manufacturing cost of the X-ray and ultrasound products by adding together direct materials, direct labor, and overhead cost applied based on the number of direct labor hours. The factory has three overhead departments that support the single production line that makes both products. Budgeted overhead spending for the departments is as follows: Pelders budgeted manufacturing activities and costs for the period are as follows: The budgeted cost to manufacture one ultrasound machine using the activity-based costing method is: a. 225. b. 264. c. 293. d. 305.arrow_forwardReducir, Inc., produces two different types of hydraulic cylinders. Reducir produces a major subassembly for the cylinders in the Cutting and Welding Department. Other parts and the subassembly are then assembled in the Assembly Department. The activities, expected costs, and drivers associated with these two manufacturing processes are given below. Note: In the assembly process, the materials-handling activity is a function of product characteristics rather than batch activity. Other overhead activities, their costs, and drivers are listed below. Other production information concerning the two hydraulic cylinders is also provided: Required: 1. Using a plantwide rate based on machine hours, calculate the total overhead cost assigned to each product and the unit overhead cost. 2. Using activity rates, calculate the total overhead cost assigned to each product and the unit overhead cost. Comment on the accuracy of the plantwide rate. 3. Calculate the global consumption ratios. 4. Calculate the consumption ratios for welding and materials handling (Assembly) and show that two drivers, welding hours and number of parts, can be used to achieve the same ABC product costs calculated in Requirement 2. Explain the value of this simplification. 5. Calculate the consumption ratios for inspection and engineering, and show that the drivers for these two activities also duplicate the ABC product costs calculated in Requirement 2.arrow_forward
- The management of Wheeler Company has decided to develop cost formulas for its major overhead activities. Wheeler uses a highly automated manufacturing process, and power costs are a significant manufacturing cost. Cost analysts have decided that power costs are mixed; thus, they must be broken into their fixed and variable elements so that the cost behavior of the power usage activity can be properly described. Machine hours have been selected as the activity driver for power costs. The following data for the past eight quarters have been collected: Required: 1. Prepare a scattergraph by plotting power costs against machine hours. Does the scatter-graph show a linear relationship between machine hours and power cost? 2. Using the high and low points, compute a power cost formula. 3. Use the method of least squares to compute a power cost formula. Evaluate the coefficient of determination. 4. Rerun the regression and drop the point (20,000; 26,000) as an outlier. Compare the results from this regression to those for the regression in Requirement 3. Which is better?arrow_forwardOverhead Rates, Unit Costs Folsom Company manufactures specialty tools to customer order. There are three producing departments. Departmental information on budgeted overhead and various activity measures for the coming year is as follows: Currently, overhead is applied on the basis of machine hours using a plantwide rate. However, Janine, the controller, has been wondering whether it might be worthwhile to use departmental overhead rates. She has analyzed the overhead costs and drivers for the various departments and decided that Welding and Finishing should base their overhead rates on machine hours and that Assembly should base its overhead rate on direct labor hours. Janine has been asked to prepare bids for two jobs with the following information: The typical bid price includes a 35% markup over full manufacturing cost. Round all overhead rates to the nearest cent. Round all bid prices to the nearest dollar. Required: 1. Calculate a plantwide rate for Folsom Company based on machine hours. What is the bid price of each job using this rate? 2. Calculate departmental overhead rates for the producing departments. What is the bid price of each job using these rates?arrow_forwardEclipse Motor Company manufactures two types of specialty electric motors, a commercial motor and a residential motor, through two production departments, Assembly and Testing. Presently, the company uses a single plantwide factory overhead rate for allocating factory overhead to the two products. However, management is considering using the multiple production department factory overhead rate method. The following factory overhead was budgeted for Eclipse: Direct machine hours were estimated as follows: In addition, the direct machine hours (dmh) used to produce a unit of each product in each department were determined from engineering records, as follows: a. Determine the per-unit factory overhead allocated to the commercial and residential motors under the single plantwide factory overhead rate method, using direct machine hours as the allocation base. b. Determine the per-unit factory overhead allocated to the commercial and residential motors under the multiple production department factory overhead rate method, using direct machine hours as the allocation base for each department. c.

- Activity-based department rate product costing and product cost distortions Big Sound Inc. manufactures two products: receivers and loudspeakers. The factory overhead incurred is as follows: The activity base associated with the two production departments is direct labor hours. The indirect labor can be assigned to two different activities as follows: The activity-base usage quantities and units produced for the two products follow: Instructions Determine the factory overhead rates under the multiple production department rate method. Assume that indirect labor is associated with the production departments, so that the total factory overhead is 420,000 and 294,000 for the Subassembly and Final Assembly departments, respectively. Determine the total and per-unit factory overhead costs allocated to each product, using the multiple production department overhead rates in (1). Determine the activity rates, assuming that the indirect labor is associated with activities rather than with the production departments. Determine the total and per-unit cost assigned to each product under activity-based costing. Explain the difference in the per-unit overhead allocated to each product under the multiple production department factory overhead rate and activity-based costing methods. production department factory overhead rate and activity-based costing methods.arrow_forwardSupport department cost allocation Blue Mountain Masterpieces produces pictures, paintings, and other home decor. The Printing and Framing production departments are supported by the Janitorial and Security departments. Janitorial costs are allocated to the production departments based on square feet, and security costs are allocated based on asset value. Information about these departments is detailed in the following table: Management has experimented with different support department cost allocation methods in the past. The different allocation methods did not yield large differences of cost allocation to the production departments. Instructions 1. Determine which support department cost allocation method Blue Mountain Masterpieces would most likely use to allocate its support department costs to the production departments. 2. Determine the total costs allocated from each support department to each production department using the method you determined in part (1). 3. Without doing calculations, consider and answer the following: If Blue Mountain Masterpieces decided to use square feet instead of asset value as the cost driver for security services, how would this change the allocation of Security Department costs?arrow_forwardA CPA would recommend changing from plantwide overhead rate application to departmental rates under which of the following circumstances? a. The plant produces one product. b. The plant produces multiple products that may or may not pass through all producing departments. c. The plant produces multiple products that pass through all of the producing departments. d.
