Starfax, Inc., manufactures a small part that is widely used in various electronic products such as home computers. Results for the first three years of operations were as follows (absorption costing basis): Sales Cost of goods sold Gross margin Selling and administrative oxpenses Het operazing income (Loss) Year 1 $ 809,600 586,960 222,640 192,280 $ 30,360 Year 2 $ 647,680 404,800 242,880 182,160 $ 60,720 Year 3 $ 809,600 627,440 182,160 172,040 $ 110,120 In the latter part of Year 2, a competitor went out of business and in the process dumped a large number of units on the market. As a result, Starfax's sales dropped by 20% during Year 2 even though production increased during the year. Management had expected sales to remain constant at 50,600 units; the increased production was designed to provide the company with a buffer of protection against unexpected spurts in demand. By the start of Year 3, management could see that it had excess inventory and that spurts in demand were unlikely. To reduce the excessive inventories, Starfax cut back production during Year 3, as shown below: Production in units Sales in unita Year 1 50,600 50,600 Year 2 60, 720 40,480 Year 40,480 50,600 Additional Information about the company follows: a. The company's plant is highly automated. Variable manufacturing expenses (direct materials, direct labor, and variable manufacturing overhead) total only $2.00 per unit, and fixed manufacturing overhead expenses total $485,760 per year. b. A new fixed manufacturing overhead rate is computed each year based on that year's actual fixed manufacturing overhead costs divided by the actual number of units produced. c. Variable selling and administrative expenses were $1 per unit sold in each year. Fixed selling and administrative expenses totaled $140,480 per year. d. The company uses a FIFO Inventory flow assumption (FIFO means first-in first-out. In other words, it assumes that the oldest units in Inventory are sold first.) Starfax's management can't understand why profits doubled during Year 2 when sales dropped by 20% and why a loss was incurred during Year 3 when sales recovered to previous levels. Required: 1. Prepare a variable costing income statement for each year. 2. Refer to the absorption costing income statements above. a. Compute the unit product cost in each year under absorption costing. Show how much of this cost is variable and how much is fixed. b. Reconcile the variable costing and absorption costing net operating income figures for each year. 5b. If Lean Production had been used during Year 2 and Year 3. what would the company's net operating income (or loss) have been in each year under absorption costing
