P 3-14A Contrasting ABC and Conventional Product Costs (LO2, LO3, LO4) Siegel Corporation manufactures a product that is available in both a deluxe and a regular model. The company has made 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 company's profits have steadily declined. Sales of the deluxe model have been increasing rapidly. Overhead is applied to products on the basis of direct labor-hours. At the beginning of the current year, management estimated that $620,000 in overhead costs would be incurred and the company would produce and sell 5,000 units of the deluxe model and 40,000 units of the regular model. The deluxe model requires 1.6 hours of direct labor time per unit, and the regular model requires 0.8 hours. Materials and labor costs per unit are given below: Deluxe Regular Direct materials cost per unit $ 150 $ 112 Direct labor cost per unit $ 16 $ 8 Requirement 1: (a) Compute the predetermined overhead rate using direct labor-hours as the basis for allocating overhead costs to products. (Round your answer to 2 decimal places. Omit the "$" sign in your response.) Predetermined overhead rate $ per DLH (b) Compute the unit product cost for one unit of each model. (Round your answer to 2 decimal places. Omit the "$" sign in your response.) Unit product cost Deluxe $ Regular $ Requirement 2: An intern suggested that the company use activity-based costing to cost its products. A team was formed to investigate this idea. It came back with the recommendation that four activity cost pools be used. These cost pools and their associated activities are listed below: Activity Activity Cost Pool and Activity Measure Deluxe Regular Total Purchase orders (number of orders) $ 21,000 400 800 1,200 Rework requests (number of requests) 11,000 300 600 900 Product testing (number of tests) 224,000 4,000 11,000 15,000 Machine-related (machine-hours) 364,000 20,000 30,000 50,000 $ 620,000 Compute the activity rate (i.e., predetermined overhead rate) for each of the activity cost pools. (Round your answer to 2 decimal places. Omit the "$" sign in your response.) Activity Cost Pool Activity Rate Purchase orders $ per order Rework requests $ per request Product testing $ per test Machine-related $ per MH Requirement 3: Assume that actual activity is as expected for the year. Using activity-based costing, do the following: (a) Determine the total amount of overhead that would be applied to each model for the year. (Do not round intermediate calculations. Round your answers to 2 decimal places. Omit the "$" sign in your response.) Total amount of overhead Deluxe $ Regular $ (b) Compute the unit product cost for one unit of each model. (Round your answers to 2 decimal places. Omit the "$" sign in your response.) Unit product cost Deluxe $ Regular $ Requirement 4: Can you identify a possible explanation for the companies declining profits? if so, what is it
