- The controller of the South Charleston plant of Ravinia, Inc., monitored activities associated with materials handling costs. The high and low levels of resource usage occurred in September and March for three different resources associated with materials handling. The number of moves is the driver. The total costs of the three resources and the activity output, as measured by moves for the two different levels, are presented as follows: Required: 1. Determine the cost behavior formula of each resource. Use the high-low method to assess the fixed and variable components. 2. Using your knowledge of cost behavior, predict the cost of each item for an activity output level of 9,000 moves. 3. Construct a cost formula that can be used to predict the total cost of the three resources combined. Using this formula, predict the total materials handling cost if activity output is 9,000 moves. In general, when can cost formulas be combined to form a single cost formula?arrow_forwardYoung 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_forwardRandy Harris, controller, has been given the charge to implement an advanced cost management system. As part of this process, he needs to identify activity drivers for the activities of the firm. During the past four months, Randy has spent considerable effort identifying activities, their associated costs, and possible drivers for the activities costs. Initially, Randy made his selections based on his own judgment using his experience and input from employees who perform the activities. Later, he used regression analysis to confirm his judgment. Randy prefers to use one driver per activity, provided that an R2 of at least 80 percent can be produced. Otherwise, multiple drivers will be used, based on evidence provided by multiple regression analysis. For example, the activity of inspecting finished goods produced an R2 of less than 80 percent for any single activity driver. Randy believes, however, that a satisfactory cost formula can be developed using two activity drivers: the number of batches and the number of inspection hours. Data collected for a 14-month period are as follows: Required: 1. Calculate the cost formula for inspection costs using the two drivers, inspection hours and number of batches. Are both activity drivers useful? What does the R2 indicate about the formula? 2. Using the formula developed in Requirement 1, calculate the inspection cost when 300 inspection hours are used and 30 batches are produced. Prepare a 90 percent confidence interval for this prediction.arrow_forward
- Evans, Inc., has a unit-based costing system. Evanss Miami plant produces 10 different electronic products. The demand for each product is about the same. Although they differ in complexity, each product uses about the same labor time and materials. The plant has used direct labor hours for years to assign overhead to products. To help design engineers understand the assumed cost relationships, the Cost Accounting Department developed the following cost equation. (The equation describes the relationship between total manufacturing costs and direct labor hours; the equation is supported by a coefficient of determination of 60 percent.) Y=5,000,000+30X,whereX=directlaborhours The variable rate of 30 is broken down as follows: Because of competitive pressures, product engineering was given the charge to redesign products to reduce the total cost of manufacturing. Using the above cost relationships, product engineering adopted the strategy of redesigning to reduce direct labor content. As each design was completed, an engineering change order was cut, triggering a series of events such as design approval, vendor selection, bill of materials update, redrawing of schematic, test runs, changes in setup procedures, development of new inspection procedures, and so on. After one year of design changes, the normal volume of direct labor was reduced from 250,000 hours to 200,000 hours, with the same number of products being produced. Although each product differs in its labor content, the redesign efforts reduced the labor content for all products. On average, the labor content per unit of product dropped from 1.25 hours per unit to one hour per unit. Fixed overhead, however, increased from 5,000,000 to 6,600,000 per year. Suppose that a consultant was hired to explain the increase in fixed overhead costs. The consultants study revealed that the 30 per hour rate captured the unit-level variable costs; however, the cost behavior of other activities was quite different. For example, setting up equipment is a step-fixed cost, where each step is 2,000 setup hours, costing 90,000. The study also revealed that the cost of receiving goods is a function of the number of different components. This activity has a variable cost of 2,000 per component type and a fixed cost that follows a step-cost pattern. The step is defined by 20 components with a cost of 50,000 per step. Assume also that the consultant indicated that the design adopted by the engineers increased the demand for setups from 20,000 setup hours to 40,000 setup hours and the number of different components from 100 to 250. The demand for other non-unit-level activities remained unchanged. The consultant also recommended that management take a look at a rejected design for its products. This rejected design increased direct labor content from 250,000 hours to 260,000 hours, decreased the demand for setups from 20,000 hours to 10,000 hours, and decreased the demand for purchasing from 100 component types to 75 component types, while the demand for all other activities remained unchanged. Required: 1. Using normal volume, compute the manufacturing cost per labor hour before the year of design changes. What is the cost per unit of an average product? 2. Using normal volume after the one year of design changes, compute the manufacturing cost per hour. What is the cost per unit of an average product? 3. Before considering the consultants study, what do you think is the most likely explanation for the failure of the design changes to reduce manufacturing costs? Now use the information from the consultants study to explain the increase in the average cost per unit of product. What changes would you suggest to improve Evanss efforts to reduce costs? 4. Explain why the consultant recommended a second look at a rejected design. Provide computational support. What does this tell you about the strategic importance of cost management?arrow_forwardLarsen, 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?arrow_forwardSilven 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.arrow_forward
- Miller Minerals Co. manufactures a product that requires the use of a considerable amount of natural gas to heat it to a desired temperature. The process requires a constant level of heat, so the furnaces are maintained at a set temperature for 24 hours a day. Although units are not continuously processed, management desires that the variable cost be charged directly to the product and the fixed cost to the factory overhead. The following data have been collected for the year: Required: 1. Separate the variable and fixed elements, using the high-low method. 2. Determine the variable cost to be charged to the product for the year. (Hint: First determine the number of annual units produced.) 3. Determine the fixed cost to be charged to factory overhead for the year.arrow_forwardThe controller for Muir Companys Salem plant is analyzing overhead in order to determine appropriate drivers for use in flexible budgeting. She decided to concentrate on the past 12 months since that time period was one in which there was little important change in technology, product lines, and so on. Data on overhead costs, number of machine hours, number of setups, and number of purchase orders are in the following table. Required: 1. Calculate an overhead rate based on machine hours using the total overhead cost and total machine hours. (Round the overhead rate to the nearest cent and predicted overhead to the nearest dollar.) Use this rate to predict overhead for each of the 12 months. 2. Run a regression equation using only machine hours as the independent variable. Prepare a flexible budget for overhead for the 12 months using the results of this regression equation. (Round the intercept and x-coefficient to the nearest cent and predicted overhead to the nearest dollar.) Is this flexible budget better than the budget in Requirement 1? Why or why not?arrow_forwardAnderson Company has the following departmental manufacturing structure for one of its products: After some study, the production manager of Anderson recommended the following revised cellular manufacturing approach: Required: 1. Calculate the total time it takes to produce a batch of 20 units using Andersons traditional departmental structure. 2. Using cellular manufacturing, how much time is saved producing the same batch of 20 units? Assuming the cell operates continuously, what is the production rate? Which process controls this production rate? 3. What if the processing times of molding, welding, and assembly are all reduced to six minutes each? What is the production rate now, and how long will it take to produce a batch of 20 units?arrow_forward
- 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?arrow_forwardThe management of Hartman Company is trying to determine the amount of each of two products to produce over the coming planning period. The following information concerns labor availability, labor utilization, and product profitability: a. Develop a linear programming model of the Hartman Company problem. Solve the model to determine the optimal production quantities of products 1 and 2. b. In computing the profit contribution per unit, management does not deduct labor costs because they are considered fixed for the upcoming planning period. However, suppose that overtime can be scheduled in some of the departments. Which departments would you recommend scheduling for overtime? How much would you be willing to pay per hour of overtime in each department? c. Suppose that 10, 6, and 8 hours of overtime may be scheduled in departments A, B, and C, respectively. The cost per hour of overtime is 18 in department A, 22.50 in department B, and 12 in department C. Formulate a linear programming model that can be used to determine the optimal production quantities if overtime is made available. What are the optimal production quantities, and what is the revised total contribution to profit? How much overtime do you recommend using in each department? What is the increase in the total contribution to profit if overtime is used?arrow_forwardGumbrecht Company has the following departmental manufacturing layout for one of its plants: A consulting firm has recommended a value stream with the following manufacturing cell: Required: 1. Calculate the total time it takes to produce a batch of 20 units using the traditional departmental manufacturing layout. 2. Using cellular manufacturing, how much time is saved producing the same batch of 20 units? Assuming the cell operates continuously, what is the production rate? Which process controls this production rate? 3. Assume the processing time of Casting is reduced to 9 minutes, while the times of the other processes stay the same. What is the production rate now, and how long will it take to produce a batch of 20 units if the cell is in a continuous production mode?arrow_forward
