Readings

5-1: “Activity-Based Costing and Predatory Pricing: The Case of the Petroleum Retail Industry” by Thomas L Burton and John B MacArthur, Management Accounting Quarterly, (Spring 2003).

The assignment of indirect costs in a volume-based costing system can lead to product-cost subsidization—overcost high-volume products and undercost low-volume products. Undercosted products can lead to the appearance of predatory pricing where it actually does not exist. This article focuses on a lawsuit brought against a major chain of retail motor fuel (gasoline) service centers for allegedly selling regular-grade gasoline below cost, as defined by state statutes. The defendant employed ABC analysis to support its position that it was not selling its regular gasoline below cost. After the ABC analysis was presented, the case was settled, and the judge lifted the initial injunction.

Discussion Questions:
1. What are product-cost subsidizations?
2. What are possible consequences of product-cost subsidizations? 3.List alternative approaches to assign costs in a gasoline service center. 4.Identify cost hierarchy level groups in classifying activities at the retail level of a gasoline service center and give at least one example each. 5.What are overheads activity-cost pools pertaining to selling gasoline in a retail gasoline service center and what is the activity level for each of the cost pools? 6.Identify the activity drivers for overheads activity-cost pools identified in this study and explain the reasons for the selection? 7.List examples of gasoline-dispensing facilities for a gasoline service center and identify whether each of the facilities is a common or a gasoline grade-specific asset.
