Transcribed Image Text:Single Plantwide Rate and Activity-Based Costing
Whirlpool Corporation (WHR) conducted an activity-based costing study of its Evansville, Indiana, plant in order to identify its most profitable products. Assume that
we select three representative refrigerators (out of 333): one low-, one medium-, and one high-volume refrigerator. Additionally, we assume the following activity-base

b. Why is the traditional overhead rate per machine hour greater under the single rate method than under the activity-based method?
The machine hour rate is greater under the single-rate method than under the activity-based method because the
allocated by machine hours
under the single-rate method. However, only a portion of the factory overhead is allocated under the machine rate method using activity-based costing. The remaining
factory overhead is allocated using the
Thus, the
for determining the machine hour rate under activity-based costing must
be less than the numerator under the single machine hour rate method.
c. Interpret Column C in your table from part (A).
Column C indicates that under activity-based costing the low-volume product has a
per-unit cost than calculated under the single-rate method. In
contrast, under activity-based costing the high-volume product has a
per-unit cost than calculated under the single-rate method. This result will
occur when there are activities that occur in proportions different from their volumes. In this case,
-volume products have setups and sales orders
occurring in higher proportions of total setups and sales orders than their proportion of machine hours to total machine hours. The opposite is the case for the
-volume product. Thus, the low-volume products are produced and ordered in
batch sizes compared to the high-volume
product. This implies that Whirlpool may wish to simplify its product line by eliminating some of the
-volume products or by attempting to reduce
the overall cost of setup and sales order processing activities.
