O’Brien Company manufactures and sells one product. The following information pertains to each of the company’s first three years of operations:

During its first year of operations, O’Brien produced 93,000 units and sold 77,000 units. During its second year of operations, it produced 78,000 units and sold 89,000 units. In its third year, O’Brien produced 84,000 units and sold 79,000 units. The selling price of the company’s product is $78 per unit.

Assume the company uses variable costing and a LIFO inventory flow assumption (LIFO means last-in first-out. In other words, it assumes that the newest units in inventory are sold first):

a. Compute the unit product cost for Year 1, Year 2, and Year 3.

b. Prepare an income statement for Year 1, Year 2, and Year 3.

Variable costs per unit: Manufacturing: Direct materials $26 Direct labor $18 Variable manufacturing overhead $5 Variable selling and administrative $3 Fixed costs per year: Fixed manufacturing overhead $530,000 Fixed selling and administrative expenses $170,000

Explanation / Answer

Solution:

(A) Under variable costing, only the variable manufacturing costs are included in product costs. So :

Year1 ($)

Unit product cost under Variable costing ($) {Total of A+B+C= D}

(B) Income Statement :

WORKING NOTES:

Year 1:

Sales (77,000 units × $78 per unit) = $6,006,000

Variable cost of goods sold (77,000 units × $49 per unit) = $3,773,000

Variable selling and administrative expenses (77,000 units × $3 per unit) = $2,31,000

Year 2:

Sales (89,000 units × $78 per unit) = $6,942,000

Variable cost of goods sold (89,000 units × $49 per unit) = $4,361,000

Variable selling and administrative expenses (89,000 units × $3 per unit) = $2,67,000

Year 3:

Sales (79,000 units × $78 per unit) = $6,162,000

Variable cost of goods sold (79,000 units × $49 per unit) = $3,871,000

Variable selling and administrative expenses (79,000 units × $3 per unit) = $2,37,000
