Using machine hours as a single activity base is likely to result in significant cost distortions
for this company. While helmet production consumes the most machine hours, only 20% of
the company’s total maintenance cost is attributed to helmet production when activity-base
costing (ABC) is used ($50,000 out of a $250,000 total). Using ABC decreases the amount of
total maintenance costs assigned to helmet production and reassigns these costs to the
