tarfax, Incorporated, 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):

	Year 1	Year 2	Year 3
Sales	$ 844,800	$ 675,840	$ 844,800
Cost of goods sold	612,480	422,400	654,720
Gross margin	232,320	253,440	190,080
Selling and administrative expenses	200,640	190,080	179,520
Net operating income (loss)	$ 31,680	$ 63,360	$ \10,560\

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, Starfaxs sales dropped by 20% during Year 2 even though production increased during the year. Management had expected sales to remain constant at 52,800 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:

	Year 1	Year 2	Year 3
Production in units	52,800	63,360	42,240
Sales in units	52,800	42,240	52,800

Additional information about the company follows:

The companys 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 $506,880 per year.

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.

Variable selling and administrative expenses were $1 per unit sold in each year. Fixed selling and administrative expenses totaled $142,240 per year.

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.)

Starfaxs management cant 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 companys net operating income (or loss) have been in each year under absorption costing?
