3. Copyright © 2006, The McGraw-Hill Companies, Inc.McGraw-Hill/Irwin Activity Based Costing (ABC) ABC is designed to provide managers with cost information for strategic and other decisions that potentially affect capacity and therefore affect fixed as well as variable costs. ABC is a good supplement to our traditional cost system I agree!

Unit-LevelActivityBatch-LevelActivityProduct-LevelActivityCustomer-LevelActivity Organization- sustaining Activity

16. Copyright © 2006, The McGraw-Hill Companies, Inc.McGraw-Hill/Irwin How Costs are Treated Under Activity–Based Costing  Unit-level activities are performed each time a unit is produced. For example, providing power to run processing equipment would be a unit-level activity.  Batch-level activities are performed each time a batch is handled or processed, regardless of how many units are in the batch. For example, setting up equipment and shipping customer orders are batch-level activities.  Product-level activities relate to specific products and must be carried out regardless of how many batches are run or units produced and sold. For example, designing or advertising a product would be product-level activities.

17. Copyright © 2006, The McGraw-Hill Companies, Inc.McGraw-Hill/Irwin How Costs are Treated Under Activity–Based Costing 4. Customer-level activities relate to specific customers and are not tied to any specific product. For example, sales calls and catalog mailings would be customer-level activities. 5. Organization-sustaining activities are carried out regardless of which customers are served, which products are produced, how many batches are run, or how many units are made. For example, heating a factory and cleaning executive offices are organization-sustaining activities.

18. Copyright © 2006, The McGraw-Hill Companies, Inc.McGraw-Hill/Irwin   Identify and Define Activities and Activity Cost Pools Activities should only be combined within a level if they are highly correlated. When combining activities, they should be grouped together only at the appropriate level.

38. Copyright © 2006, The McGraw-Hill Companies, Inc.McGraw-Hill/Irwin Differences Between ABC and Traditional Product Costs Product margins are different for four reasons:  Traditional costing assigns design costs to both products based on machine hours. ABC assigns product design costs to a product only if product design work is required.  Traditional costing assigns customer order costs, a batch- level cost, using a unit-level allocation base, machine hours. ABC assigns these batch-level costs using a batch-level activity measure.  Traditional costing assigns only manufacturing costs to products. ABC also assigns nonmanufacturing costs to products.  Traditional costing assigns all manufacturing costs to products. The ABC system does not assign organization- sustaining manufacturing costs to the products.

39. Copyright © 2006, The McGraw-Hill Companies, Inc.McGraw-Hill/Irwin Differences Between ABC and Traditional Product Costs When batch-level and product-level costs are present, ABC will usually shift costs from high volume products, produced in large batches, to low volume products produced in small batches. This cost shifting will usually have its greatest impact on the per unit cost of the low volume products.

40. Copyright © 2006, The McGraw-Hill Companies, Inc.McGraw-Hill/Irwin Targeting Process Improvement Activity-based management is used in conjunction with ABC to identify areas that would benefit from process improvements. While the theory of constraints approach discussed in Chapter 1 is a powerful tool for targeting improvement efforts, activity rates can also provide valuable clues on where to focus improvement efforts.

41. Copyright © 2006, The McGraw-Hill Companies, Inc.McGraw-Hill/Irwin Activity-Based Costing and External Reporting Most companies do not use ABC for external reporting because... 1.External reports are less detailed than internal reports. 2.It may be difficult to make changes to the company’s accounting system. 3.ABC does not conform to GAAP. 4.Auditors may be suspect of the subjective allocation process based on interviews with employees. 1.External reports are less detailed than internal reports. 2.It may be difficult to make changes to the company’s accounting system. 3.ABC does not conform to GAAP. 4.Auditors may be suspect of the subjective allocation process based on interviews with employees.

42. Copyright © 2006, The McGraw-Hill Companies, Inc.McGraw-Hill/Irwin ABC Limitations Substantial resources required to implement and maintain. Resistance to unfamiliar numbers and reports. Desire to fully allocate all costs to products. Potential misinterpretation of unfamiliar numbers. Does not conform to GAAP. Two costing systems may be needed.
