ElectronPlus manufactures and sells a unique electronic part. Operating results for the first three years of activity were as follows (absorption costing basis): Sales dropped by 20% during year 2 due to the entry of several foreign competitors into the market. ElectronPlus had expected sales to ws remain constant at 50,000 units for the year; production was set at 60,000 units in order to build a buffer against unexpected spurts in demand. By the start of year 3, management could see that spurts in demand were unlikely and that the imentory was excessive. To work off the excessive imventories, ElectronPlus cut back production during year 3, as shown below: Additional information about the company follows: a. The company's plant is highly automated. Variable manufacturing costs (direct materials, direct labour, and variable manufacturing overhead) total only $4 per unit, and fiwed manufacturing coverhcad costs total $600,000 per year. b. Fixed manufacturing coerhead costs are applied to units of product on the basis of each year's planned production. (That is, a new fixed overhead rate is computed each year, as in (8 Exhibit 8-5.) c Variable selling and administrative expenses are $2 per unit sold. Fiwed selling and administrative expenses total $70,000 per year. d. The company uses a FIFO inventory flow assumption. Management of ElectronPlus can't understand why profits tripled during year 2 when sales dropped by 20%, and why a loss was incurred during year 3 when sales recovered to previous levels. Requined Management of Electronllus can't understand why profits tripled during year 2 when sales dropped by 20%, and why a loss was incurred during year 3 when sales recovered to previous levels. Requind 1. Prepare a contribution format income statement for each year using variable costing. 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 operating income figures for each year. 3. Refer again to the absorption costing income statements. Explain why operating income was higher in year 2 than it was in year 1 under the absorption approach, in light of the fact that fewer units were sold in year 2 than in year I. 4. Refer again to the absorption costing income statements. Explain why the company suffered a loss in year 3 but reported a proflt in year 1 , although the same number of units was sold in each year. 5. a. Explain how operations would have differed in year 2 and year 3 if the compary had been using lean production, with the result that ending imventory was zero. b. If lean production had been in use during year 2 and year 3, what would the company's operating income (or loss) have been in each year under absorption costing? Explain the reason for any differences between these income figures and the figures reported by the company in the statements above
