Ch. 7 - Activity Based Costing (ABC) Flashcards
Plant-wide Overhead Rate
A single overhead rate used throughout an entire factory
Why was direct labour used as the allocation base for overhead in the past?
- Direct labour information was already being recorded
- Direct labour was a large component of product costs
- Managers believed direct labour and overhead costs were highly correlated
Departmental Overhead Rates
Each department has its own overhead rate that uses its own allocation base
What is the disadvantage of using departmental overhead rates?
Departmental rates will not correctly assign overhead in situations where a company has a range of products and complex overhead costs. It relies exclusively on volume-related allocation bases (some overhead costs may be caused by non volume-related factors)
How does ABC differ from traditional costing?
- ABC assigns both manufacturing and non-manufacturing costs to products
- ABC does not assign all manufacturing costs to products
- ABC uses more cost pools
- ABC bases level of activity on capacity
What are the 5 classes of costs?
- Unit-level costs
- Batch-level costs
- Product-level costs
- Customer-level costs
- Organization-sustaining costs
Unit-level Costs
Costs that vary proportionally with the number of units produced
Batch-level Costs
Costs that are incurred each time a batch of goods is processed
Product-level Costs
Costs incurred to enable individual products to be produced or sold
Customer-level Costs
Costs related to specific customers
Organization-sustaining Costs
Costs incurred to create productive capacity for all products
In what situations is it appropriate to implement ABC?
When an organization:
- uses large amounts of indirect resources in its production processes
- has diversity in products, production processes, and customers
- faces significant competition
Benefits of ABC
- Improved decisions
- Continuously improve activities to reduce overhead costs
- Ease of determining relevant costs
Limitations of ABC
- Substantial resources required to implement and maintain
- Data can be misinterpreted (need to accurately identify relevant costs)
- Does not conform to GAAP (cannot use for external reporting)
