Answer 1

1. Absorption Costing Income Statement

For the month ended May 31, 2016

Sales $10,800,000

Cost of goods sold

Beginning inventory -

Cost of goods manufactured $9,600,000

Ending Inventory $960,000

Cost of goods sold $8,640,000

Gross margin $2,160,000

Selling and administrative expenses

$1,080,000 + $180,000 $1,260,000

Income from operation $900,000

2. Variable Costing Income Statement

For the month ended May 31, 2016

Sales $10,800,000

Variable cost of goods sold

Beginning Inventory -

Variable cost of goods manufactured $9,280,000

Ending Inventory $928,000

Variable cost of goods sold $8,352,000

Manufacturing margin $2,448,000

Variable selling and administrative $1,080,000

expenses

Contribution margin $1,368,000

Fixed Cost:

Fixed manufacturing cost $320,000

Fixed selling and administrative $180,000

expenses

Total fixed cost $500,000

Income from operation $868,000

3. The reason for difference of amount for income from operation is $32,000 ($900,000 - $868,000). It is due to fixed manufacturing cost which is included for ending inventory under absorption costing (320,000 / 80,000 * 8,000). Hence, income under absorption costing is higher by $32,000 as compared to income under variable costing.
