  1. COST MANAGEMENT Don R. Hansen Maryanne M. Mowen

  2. Chapter Four Product and Service Costing: Overhead Application and Job-Order System

  3. Learning Objectives • Differentiate the cost accounting systems of service and manufacturing firms and of unique and standardized products. • Discuss the interrelationship of cost accumulation, cost measurement, and cost assignment. • Compute a predetermined overhead rate, and use the rate to assign overhead to production.

  4. Learning Objectives (continued) • Explain the difference between job-order and process costing, and identify the source documents used in job-order costing. • Describe the cost flows associated with job-order costing, and prepare the journal entries. • Explain why multiple overhead rates may be preferred to a single, plantwide rate.

  5. Manufacturing Firms VersusService Firms Manufacturing involves putting together materials, labor, and overhead to produce a new product. The good produced is tangible and can be inventoried and transported from the plant to the customer. A service is characterized by its intangible nature. It is not separable from the customer and cannot be inventoried.

  6. Interface of Services with theCost Management System 1. Intangibility 2. Perishability 3. Inseparability 4. Heterogeneity

  7. Intangibility Relationship to Business Impact on Cost Management System Services cannot be stored. Services cannot be protected through patents. Services cannot readily be displayed or communicated. Prices are difficult to set. There are no inventory accounts. There is a strong ethical code.* Costs must be related to entire organization.* *Many of these effects are also true of tangible products.

  8. Inseparability Relationship to Business Impact on Cost Management System Consumer is involved in production. Other consumers are involved in production Centralized mass production of services is difficult. Costs often accounted for by customer type.* System must be generated to encourage consistent quality.* *Many of these effects are also true of tangible products.

  9. Heterogeneity Relationship to Business Impact on Cost Management System Standardization and quality control are difficult. A strong systems approach is needed. Productivity measurement is ongoing.* Total quality management is critical.* *Many of these effects are also true of tangible products.

  10. Perishability Relationship to Business Impact on Cost Management System Service benefits expire quickly. Service may be repeated often for one customer. There are no inventories. There needs to be a standardized system to handle repeat customers.* *Many of these effects are also true of tangible products.

  11. Relationship of Cost Accumulation, Cost Measurement, and Cost Assignment Cost Measurement Classify Costs: Cost Assignment Assign to Cost Objects: Cost Accumulation Record Costs: Purchase materials Assemblers’ payroll Finishers’ payroll Supervisors’ payroll Depreciation Utilities Property taxes Landscaping Direct Materials Direct Labor Overhead Product 1 Product 2

  12. Cost Accumulation Cost accumulation refers to the recognition and recording of costs. The cost accountant needs to develop source documents, which keep track of costs as they occur. A source document describes a transaction. Data from these source documents can then be recorded in a data-base. Well-designed source documents can supply information in a flexible way.

  13. Cost Measurement There are two commonly used ways to measure the costs associated with production: actual costing and normal costing. An actual cost system uses actual costs for direct materials, direct labor, and overhead to determine unit cost. Normal costing systems measure overhead costs on a predetermined basis and use actual costs for direct materials and direct labor.

  14. Johnson Leathergoods - Example Suppose that Stan Johnson forms a new company, Johnson Leathergoods, which specializes in the production of custom leather products. Stan believes that there is a market for one-of-a-kind leather purses, briefcases, and backpacks. In its first month of operations, he obtains two orders: the first is for 20 leather backpacks for a local sporting goods store; the second is for 10 distinctively tooled briefcases for the coaches of a local college. Stan agrees to provide these orders at a price of cost plus 50 percent.

  15. Johnson Leathergoods - Unit Cost Direct materials $1,000 Direct labor 1,080 Overhead 240 Total $2,320  number of units  20 Unit cost $ 116 ======

  16. Overhead Application a NormalCosting View A predetermined overhead rate is calculated using the following formula: Overhead rate = Budgeted annual overhead/Budgeted annual activity level

  17. Choosing the Activity Base 1. Units produced 2. Direct labor hours 3. Direct labor dollars 4. Machine hours 5. Direct materials

  18. Choosing the Activity Level Expected activity level is simply the production level the firm expects to attain for the coming year. Normal activity level is the average activity usage that a firm experiences in the long term (normal volume is computed over more than one year). Theoretical activity level is the absolute maximum production activity of a manufacturing firm. Practical activity level is the maximum output that can be realized if everything operates efficiently.

  19. Basic Concept of Overhead Application In attempting to understand the concept of applied overhead, there are two points that should be emphasized. 1. Applied overhead is the basis for computing per-unit overhead cost. 2. Applied overhead is rarely equal to a period’s actual overhead.

  20. Overhead Application Example Suncalc, Inc., produces two unique, solar-powered products: a pocket calculator and a currency translator used to convert foreign currency exchange rates into dollars and vice versa. The company has the following estimated and actual data for 2001: Budgeted overhead $360,000 Normal activity (in direct labor hours) 120,000 Actual activity (in direct labor hours) 100,000 Actual overhead $320,000

  21. Overhead Application Example (continued) Now assume that the firm bases its predetermined overhead rate on normal activity measured in direct labor hours (DLH). Thus, for 2001: Predetermined overhead rate = Budgeted overhead/Normal activity = $360,000/120,000 direct labor hours = $3 per DLH Using the overhead rate, applied overhead for 2001 is: Applied overhead = Overhead rate x Actual activity usage = $3 per DLH x 100,000 DLH = $300,000

  22. Overhead Application Example (continued) Pocket Currency CalculatorTranslator Units produced 80,000 90,000 Direct labor hours 40,000 60,000 Overhead applied to production ($3 x DLH) $120,000 $180,000 Overhead per unit $1.50 $2.00

  23. Overhead Variance The difference between actual overhead and applied overhead an overhead variance. If actual overhead is greater than applied overhead, then the variance is called underapplied overhead. If applied overhead is greater than actual overhead, the the variance is called overapplied overhead. The firm has underapplied overhead by ($320,000 - $300,000) or $20,000

  24. Disposition of Overhead Variance The overhead variance is disposed of in one of two ways. 1. All overhead variance is allocated to cost of goods sold. 2. The overhead variance is allocated among work in process, finished goods, and cost of goods sold.

  25. Comparison of Job-order andProcess Costing Job-Order CostingProcess Costing 1. Wide variety of distinct 1. Homogeneous products products 2. Cost accumulated by job 2. Costs accumulated by process or department 3. Unit cost computed by 3. Unit cost computed by dividing total job costs dividing process costs of by units produced on that the period by the units job produced in the period

  46. Accounting for Spoilage If the defective work was a consequence of the demanding nature of this particular job, then rework (spoilage) is assigned to the job. On the other hand, if the defective work was a consequence of assigning new, untrained labor to the job, then the rework (spoilage) is assigned to overhead control.
