Weighted-average method. McKnight Handcraft is a manufacturer of picture frames for large retailers. Every picture frame passes through two departments: the assembly department and the finishing department. This problem focuses on the assembly department. The process-costing system at McKnight has a single direct-cost category (direct materials) and a single indirect-cost category (conversion costs). Direct materials are added when the assembly department process is 10% complete. Conversion costs are added evenly during the assembly department’s process.
McKnight uses the weighted-average method of
a Degree of completion: direct materials, 100%; conversion costs, 40%.
b Degree of completion: direct materials, 100%; conversion costs, 15%.

- 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_forwardBenson Pharmaceuticals uses a process-costing system to compute the unit costs of the over-the-counter cold remedies that it produces. It has three departments: mixing, encapsulating, and bottling. In mixing, the ingredients for the cold capsules are measured, sifted, and blended (with materials assumed to be uniformly added throughout the process). The mix is transferred out in gallon containers. The encapsulating department takes the powdered mix and places it in capsules (which are necessarily added at the beginning of the process). One gallon of powdered mix converts into 1,500 capsules. After the capsules are filled and polished, they are transferred to bottling, where they are placed in bottles that are then affixed with a safety seal, lid, and label. Each bottle receives 50 capsules. During March, the following results are available for the first two departments: Overhead in both departments is applied as a percentage of direct labor costs. In the mixing department, overhead is 200% of direct labor. In the encapsulating department, the overhead rate is 150% of direct labor. Required: 1. Prepare a production report for the mixing department using the weighted average method. Follow the five steps outlined in the chapter. (Note: Round to two decimal places for the unit cost.) 2. Prepare a production report for the encapsulating department using the weighted average method. Follow the five steps outlined in the chapter. (Note: Round to four decimal places for the unit cost.) 3. CONCEPTUAL CONNECTION Explain why the weighted average method is easier to use than FIFO. Explain when weighted average will give about the same results as FIFO.arrow_forwardThe following product costs are available for Stellis Company on the production of erasers: direct materials, $22,000; direct labor, $35,000; manufacturing overhead, $17,500; selling expenses, $17,600; and administrative expenses; $13,400. What are the prime costs? What are the conversion costs? What is the total product cost? What is the total period cost? If 13,750 equivalent units are produced, what is the equivalent material cost per unit? If 17,500 equivalent units are produced, what is the equivalent conversion cost per unit?arrow_forward
- Crystal Scarves Co. produces winter scarves. The scarves are produced in the Cutting and Sewing departments. The Maintenance and Security departments support these production departments, and allocate costs based on machine hours and square feet, respectively. Information about each department is provided in the following table: Using the sequential method and allocating the support department with the highest costs first, allocate all support department costs to the production departments. Then compute the total cost of each production department.arrow_forwardCharlies Wood Works produces wood products (e.g., cabinets, tables, picture frames, and so on). Production departments include Cutting and Assembly. The Janitorial and Security departments support the Cutting and Assembly departments. The Assembly Department spans about 46,400 square feet and holds assets valued at about 60,000. The Cutting Department spans about 33,600 square feet and holds assets valued at about 140,000. Charlies Wood Works allocates support department costs using the direct method. If costs from the Janitorial Department are allocated based on square feet and costs from the Security Department are allocated based on asset value, determine (a) the percentage of Janitorial costs that should be allocated to the Assembly Department and (b) the percentage of Security costs that should be allocated to the Cutting Department.arrow_forwardBienestar Inc., has the following departmental structure for producing a well-known multivitamin: A consultant designed the following cellular manufacturing structure for the same product: The times above the processes represent the time required to process one unit of product. Required: 1. Calculate the time required to produce a batch of 15 bottles using a batch-processing departmental structure. 2. Calculate the time to process 15 units using cellular manufacturing. 3.

- Kenkel, Ltd. uses backflush costing to account for its manufacturing costs. The trigger points are the purchase of materials, the completion of goods, and the sale of goods. Prepare journal entries to account for the following: a. Purchased raw materials, on account, 80,000. b. Requisitioned raw materials to production, 80,000. c. Distributed direct labor costs, 10,000. d. Factory overhead costs incurred, 60,000. (Use Various Credits for the account in the credit part of the entry.) e. Completed all of the production started. f. Sold the completed production for 225,000, on account.arrow_forwardA company is using process costing with the first-in, first-out (FIFO) method, and all costs are added evenly throughout the manufacturing process. If there are 5,000 units in beginning work in process inventory (30% complete), 10,000 units in ending work in process inventory (60% complete), and 25,000 units started in process this period, how many equivalent units are there for this period? a. 22,500 units. b. 26,000 units. c. 24,500 units. d. 25,000 units.arrow_forwardHandy Leather, Inc., produces three sizes of sports gloves: small, medium, and large. A glove pattern is first stencilled onto leather in the Pattern Department. The stenciled patterns are then sent to the Cut and Sew Department, where the glove is cut and sewed together. Handy Leather uses the multiple production department factory overhead rate method of allocating factory overhead costs. Its factory overhead costs were budgeted as follows: The direct labor estimated for each production department was as follows: Direct labor hours are used to allocate the production department overhead to the products. The direct labor hours per unit for each product for each production department were obtained from the engineering records as follows: a. Determine the two production department factory overhead rates. b. Use the two production department factory overhead rates to determine the factory overhead per unit for each product.arrow_forward
- Medical Tape makes two products: Generic and Label. It estimates it will produce 423,694 units of Generic and 652,200 of Label, and the overhead for each of its cost pools is as follows: It has also estimated the activities for each cost driver as follows: How much is the overhead allocated to each unit of Generic and Label?arrow_forwardBrees, Inc., a manufacturer of golf carts, has just received an offer from a supplier to provide 2,600 units of a component used in its main product. The component is a track assembly that is currently produced internally. The supplier has offered to sell the track assembly for 66 per unit. Brees is currently using a traditional, unit-based costing system that assigns overhead to jobs on the basis of direct labor hours. The estimated traditional full cost of producing the track assembly is as follows: Prior to making a decision, the companys CEO commissioned a special study to see whether there would be any decrease in the fixed overhead costs. The results of the study revealed the following: 3 setups1,160 each (The setups would be avoided, and total spending could be reduced by 1,160 per setup.) One half-time inspector is needed. The company already uses part-time inspectors hired through a temporary employment agency. The yearly cost of the part-time inspectors for the track assembly operation is 12,300 and could be totally avoided if the part were purchased. Engineering work: 470 hours, 45/hour. (Although the work decreases by 470 hours, the engineer assigned to the track assembly line also spends time on other products, and there would be no reduction in his salary.) 75 fewer material moves at 30 per move. Required: 1. Ignore the special study, and determine whether the track assembly should be produced internally or purchased from the supplier. 2. Now, using the special study data, repeat the analysis. 3. Discuss the qualitative factors that would affect the decision, including strategic implications. 4. After reviewing the special study, the controller made the following remark: This study ignores the additional activity demands that purchasing would cause. For example, although the demand for inspecting the part on the production floor decreases, we may need to inspect the incoming parts in the receiving area. Will we actually save any inspection costs? Is the controller right?arrow_forwardMakani Handcraft is a manufacturer of picture frames for large retailers. Every picture frame passes through two departments: the assembly department and the finishing department. This problem focuses on the assembly department. The process-costing system at Makani has a single direct-cost category (direct materials) and a single indirect-cost category (conversion costs). Direct materials are added at the beginning of the process. Conversion costs are added evenly during the assembly department's process.
