❖ To compete in the marketplace, some companies have had to cut the prices of high volume popular items.
❖ But They have been able to achieve high mark-ups on low volume specialty products.

❖ The result:
High-volume simple products are overcosted and over-priced
Low-volume complex products are under-costed and under-priced
Plantwide Overhead Rates
Causes of problems
❖ Increased product diversity ❖ changing cost structures ❖ use of volume-based cost drivers Have resulted in:
distorted product costs
Cost Distortions caused by 2stage allocations
❖ There is a no link between the cause of support activity costs and the basis for assigning these costs to products

Evolution of ABC
❖ Conventional costing systems use a twostage allocation process: 1. service department costs are allocated to production departments. 2. production department overhead costs are allocated to products using a volume-based predetermined overhead rate.

Erosion of company profits
❖ Price cuts produce increased sales in units but decreased total revenue
❖ High mark-ups on specialty products didn’t offset the fall in profit margins of high volume products
Product costs don’t make sense
❖ Problem: There may be no relationship between the overhead application base and the way that different products cause overhead costs
Companies have tended to use direct labour as the overhead application base.
However direct labour is now a relatively minor part of total manufacturing cost. Many tasks that used to be done by hand are now done by automated equipment.
❖ Why?
1. Allocations are based on unit or volume related measures.
2. Different products consume different amounts of support activities.
Questionable profit margins
and then to products.
