Importance of Manufacturing Overhead Allocation
The percentages of product costs comprised by direct materials, direct labor, and manufacturing overhead for three companies are as follows:

Direct Labor.................................. 13 42 49
Manufacturing Overhead.................. 80 37 9

Based on this information, which of these three companies would probably improve its product costing accuracy most by converting to activity-based costing (ABC)? Explain your answer.
