Darwin Company manufactures only one product that it sells for $200 per unit. The company uses plantwide overhead cost allocation based on the number of units produced. It provided the following estimates at the beginning of the year:

Number of units produced . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .       50,000
Total fixed manufacturing overhead costs . . . . . . . . . . . . . . . . . . $1,000,000
Variable manufacturing overhead per unit produced . . . . . . . . . $            12

During the year, the company had no beginning inventories of any kind and no ending raw materials or work in process inventories. All raw materials were used in production as direct materials. An unexpected business downturn caused annual sales to drop to 38,000 units. In response to the decline in sales, Darwin decreased its annual production to 40,000 units. The company’s actual costs for the year were as follows:

Variable costs per unit:

Manufacturing:

Direct materials . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $78
Direct labor . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $60
Variable manufacturing overhead . . . . . . . . . . . . . . . $12
Variable selling and administrative . . . . . . . . . . . . . . $15

Fixed costs per year:
Fixed manufacturing overhead . . . . . . . . . . . . . . . . . . $1,000,000
Fixed selling and administrative expenses . . . . . . . . $350,000

Required:

1. Assuming the company uses normal costing (as described in Chapters 2 and 3):

a. Compute the plantwide predetermined overhead rate.

b. Compute the unit product cost for each unit produced during the year.

c. Prepare a schedule of cost of goods manufactured and a schedule of cost of goods sold. Assume that any underapplied or overapplied overhead is closed entirely to cost of goods sold.

d. Compute absorption costing net operating income for the year.

2. Assuming the company uses actual costing (as described in Chapter 6):

a. Compute the unit product cost for each unit produced during the year.

b. Compute absorption costing net operating income for the year.

3. Are your normal costing and actual costing net operating incomes the same? Why? Support your answer with computations.
