2. 4-2  Allocates overhead using a predetermined rate. ► Job order costing: direct labor cost may be the relevant activity base. ► Process costing: machine hours may be the relevant activity base. Traditional Costing Systems LEARNING OBJECTIVE Discuss the difference between traditional costing and activity-based costing. 1 LO 1

3. 4-3 Atlas Company produces two abdominal fitness products—the Ab Bench and the Ab Coaster. The direct materials cost per unit is $40 for the Ab Bench and $30 for the Ab Coaster. The direct labor cost is $12 per unit for each product. Both products require one direct labor hour per unit, both products are allocated overhead cost of $30 per unit. Illustration 4-3 Total unit costs— traditional costing Illustration of a Traditional Costing System LO 1

4. 4-4  Tremendous change in manufacturing and service industries.  Decrease in amount of direct labor usage.  Significant increase in total overhead costs.  Inappropriate to use plantwide predetermined overhead rates when a lack of correlation exists.  Complex manufacturing processes may require multiple allocation bases; this approach is called activity-based costing (ABC). The Need for a New Approach LO 1

5. 4-5 An approach for allocating overhead costs.  Allocates overhead to multiple activity cost pools.  Assigns the activity cost pools to products or services by means of cost drivers. Activity-Based Costing LO 1

6. 4-6 2. Identify the cost driver that has a strong correlation to the costs accumulated in each cost pool. Activity-Based Costing (Four Steps) 1.Identify and classify the activities involved in the manufacture of specific products and assign overhead to cost pools. 3. Compute the activity-based overhead rate for each cost pool. 4. Allocate overhead costs to products using the overhead rates determined for each cost pool. LO 1

7. 4-7 ABC allocates overhead in a two-stage process:  Stage 1: Overhead costs are assigned to activity cost pools (Step 1).  Stage 2: Allocates overhead assigned to the activity cost pools to products, using cost drivers (Steps 2-4). The more complex a product’s manufacturing operation, the more activities and cost drivers are likely to be present. Activity-Based Costing LO 1

8. 4-8 Illustration 17-2 Activities and related cost drivers Illustration 4-5 Activities and related cost drivers LO 1

9. 4-9 Solution: 1. False. 2. True. 3. True. 4. False. 5. True. Indicate whether the following statements are true or false. 1.A traditional costing system allocates overhead by means of multiple overhead rates. 2.Activity-based costing allocates overhead costs in a two-stage process. 3.Direct material and direct labor costs are easier to trace to products than overhead. 4.As manufacturing processes have become more automated, more companies have chosen to allocate overhead on the basis of direct labor costs. 5.In activity-based costing, an activity is any event, action, transaction, or work sequence that incurs cost when producing a product. 1 Costing Systems LO 1

10. 4-10 Activity-Based Costing Involves the following four steps. 1.Identify and classify the activities involved in the manufacture of specific products and assign overhead to cost pools. 2.Identify the cost driver that has a strong correlation to the costs accumulated in each cost pool. 3.Compute the activity-based overhead rate for each cost pool. 4.Allocate overhead costs to products, using the overhead rates determined for each cost pool. LEARNING OBJECTIVE Apply activity-based costing to a manufacturer. 2 LO 2

11. 4-11 Overhead costs are assigned directly to the appropriate activity cost pool. Identify and Classify Activities and Allocate Overhead to Cost Pools (Step 1) Illustration 4-6 Activity cost pools and estimated overhead LO 2

12. 4-12 Cost driver must accurately measure the actual consumption of the activity by the various products. Illustration 4-6: Cost drivers that Atlas Company identifies and their total expected use per activity cost pool. Illustration 4-7 Identify Cost Drivers (Step 2) LO 2

13. 4-13 Illustration 4-8 Illustration 4-9 Next, the company computes an activity-based overhead rate per cost driver. Compute Activity-Based Overhead Rates (Step 3) LO 2

14. 4-14 In allocating overhead costs, it is necessary to know the expected use of cost drivers for each product. Because of its low volume and higher number of components, the Ab Coaster requires more setups and purchase orders than the Ab Bench. Illustration 17-8 Allocate Overhead Costs to Products (Step 4) Illustration 4-10 Expected use of cost drivers per product LO 2

15. 4-15 Illustration 4-11 Allocation of activity cost pools to products To allocate overhead costs, Atlas multiplies the activity-based overhead rates per cost driver (Ill. 4-9) by the number of cost drivers expected to be used per product (Ill. 4-10). LO 2 Allocate Overhead Costs to Products (Step 4)

16. 4-16 Illustration 4-11 LO 2 To allocate overhead costs, Atlas multiplies the activity-based overhead rates per cost driver (Ill. 4-9) by the number of cost drivers expected to be used per product (Ill. 4-10). Allocate Overhead Costs to Products (Step 4)

17. 4-17 Likely consequence of differences in assigning overhead.  Overpricing the Ab Bench and possibly losing market share to competitors.  Sacrificing profitability by underpricing the Ab Coaster. Illustration 17-10 Comparing Unit Costs Illustration 4-12 Comparison of unit product costs LO 2
