Siegel Company manufactures a product that is available in both a deluxe model and a regular model. The company has manufactured the regular model for years. The deluxe model was introduced several years ago to tap a new segment of the market. Since introduction of the deluxe model, the companys profits have steadily declined and management has become increasingly concerned about the accuracy of its costing system. Sales of the deluxe model have been increasing rapidly.

Manufacturing overhead is assigned to products on the basis of direct labor-hours. For the current year, the company has estimated that it will incur $5,503,800 in manufacturing overhead cost and produce 15,000 units of the deluxe model and 112,000 units of the regular model. The deluxe model requires 1.0 hours of direct labor time per unit, and the regular model requires 0.5 hour. Material and labor costs per unit are as follows:

Model Deluxe Regular Direct materials $ 145 $ 116 Direct labor $ 10 $ 11

Required:

1-a. Using direct labor-hours as the base for assigning manufacturing overhead cost to products, compute the predetermined overhead rate.

1-b. Using the predetermined overhead rate computed in 1-a above and other data from the problem, determine the unit product cost of each model.

2. Management is considering using activity-based absorption costing to apply manufacturing overhead cost to products. The activity-based system would have the following four activity cost pools:

Activity Cost Pool Activity Measure Estimated Overhead Cost Purchasing Purchase orders issued $ 352,800 Processing Machine-hours 3,210,000 Scrap/rework Scrap/rework orders issued 459,000 Shipping Number of shipments 1,482,000 $ 5,503,800

Expected Activity

Activity Measure Deluxe Regular Total Purchase orders issued 490 980 1,470 Machine-hours 21,400 32,100 53,500 Scrap/rework orders issued 375 300 675 Number of shipments 6,240 9,360 15,600

Determine the predetermined overhead rate for each of the four activity cost pools.

3. Using the predetermined overhead rates you computed in part (2), do the following:

a. Compute the total amount of manufacturing overhead cost that would be applied to each model using the activity-based absorption costing system. After these totals have been computed, determine the amount of manufacturing overhead cost per unit of each model.

b. Compute the unit product cost of each model (direct materials, direct labor, and manufacturing overhead).
