A company produces and sells three products: X, Y and Z. Production takes 25, 25 and 10 machine hours to manufacture 1,000-unit batches of X, Y and Z, respectively. The following additional data apply: X Y Z Projected sales in units 30,000 50,000 40,000 PER UNIT data: Selling price 40 20 30 Direct materials 8 4 8 Direct labor 15 3 9 Overhead cost based on direct labor hours (traditional system) 12 3 9 Hours per 1000-unit batch: Direct labor hours 40 10 30 Machine hours 25 25 10 Setup hours 1.0 0.5 1.0 Inspection hours 30 20 20 Total overhead costs and activity levels for the year are estimated as follows: Activity Overhead costs Activity levels Direct labor hours 2,900 hours Machine hours 2,400 hours Setups 465,500 95 setup hours Inspections 405,000 2,700 inspection hours 870,500 Required: (a) Using the traditional system, determine the operating profit per unit for the product X. (b) Determine the activity-cost-driver rate for setup costs and inspection costs. (c) Using ABC system, for the product X: (i) compute the estimated overhead costs per unit. (ii) compute the estimated operating profit per unit. (d) Explain the difference between the profit obtained from the traditional system and the ABC system. Which system provides a better estimate of profitability? Why?
