Harrison Company makes two products and uses a conventional costing system in which a single plant-wide predetermined overhead rate is computed based on direct labor-hours. Data for the two products for the upcoming year follow:

Rascon Parcel

Direct materials cost per unit: $13.00 $22.00

Direct labor cost per unit: $6.00 $3.00

Direct labor-hours per unit: 0.40 0.20

Number of units produced 20,000 80,000

These products are customized to some degree for specific customers.

Required:

1. The companys manufacturing overhead cost for the year are expected to be $576,000. Using the companys conventional costing system, compute the unit product cost for the two products.

2. Management is considering an activity-based costing system in which half of the overhead would continue to be allocated on the basis of direct labor-hours, and half would be allocated on the basis of engineering design time. This time is expected to be distributed as follows during the upcoming year.

Rascon Parcel Total

Engineering design time (in hours) 3,000 3,000 6,000

Compute the unit product cost for the two products using the proposed ABC system.

3. Explain why the product cost differs between the two systems.
