Required:
- 1. Reconcile Lehighton’s operating income reported under absorption and variable costing, during each year, by comparing the following two amounts on each income statement:
- Cost of goods sold
- Fixed cost (expensed as a period expense)
- 2. What was Lehighton’s total operating income across both years under absorption costing and under variable costing?
- 3. What was the total sales revenue across both years under absorption costing and under variable costing?
- 4. What was the total of all costs expensed on the operating income statements across both years under absorption costing and under variable costing?

- 6. Comment on the results obtained in requirements (1), (2), (3), and (4) in light of the following assertion: Timing is the key in distinguishing between absorption and variable costing.
1.
Reconcile the reported operating income of company L for each year under absorption and variable costing, by comparing the cost of goods sold and fixed cost on each income statement.
Explanation of Solution
Absorption Costing: “Absorption costing is a method that allocates “direct labor, direct materials, fixed manufacturing overhead and variable manufacturing overhead” to products and it is required by GAAP for the purpose of external reporting”.
Variable Costing: Managers frequently use variable costing for internal purposes for taking decision making. The cost of goods manufactured includes direct materials, direct labor, and variable factory overhead. Fixed factory overhead treated as period (fixed) expense.
Reconcile the reported operating income of company L for each year under absorption and variable costing as follows:
For year 1:

5.
Deduct the total costs expensed from the total sales revenue of company L for both years (a) under absorption costing and (b) under variable costing.
Explanation of Solution
a. Deduct the total costs expensed from the total sales revenue of company L for both years under absorption costing as follows:
b. Deduct the total costs expensed from the total sales revenue of company L for both years under variable costing as follows:
6.
Evaluate the results of the above calculation.
Explanation of Solution
- In this case, the company has sold same number of (2,500) units for both years, at a price of $50. Therefore, the total sales revenue is same for both years under absorption and variable costing and sales revenue has nothing to do with the costing method used.
- The total costs expensed ($209,000) for both years are also same under variable and absorption costing. Because the company has sold the same number of units for both years.
- The combined operating income of Company L for the two-year period is $41,000 under both absorption and variable costing. Because the total sales revenue and the total expenses of the company are same under both costing methods over the two-year.
- The analysis in requirement (1) indicates that the operating income of company L is distributed differently for both years under absorption and variable costing. Therefore, the operating income under the two costing methods is not the same within each year. Under absorption costing, the operating income is higher by $7,000 for year 1 and for year 2 it is lower by $7,000. Because the expenses under absorption costing are $7,000 lower in year 1 and $7,000 greater in year 2. However, it reported the same operating income across the two-year combined period under both costing methods.
- Therefore, the difference between absorption and variable costing is caused by the timing with which expenses are recognized. For instance: Under absorption costing, the fixed manufacturing overhead is not expensed until year 2. Whereas, under variable costing all of the fixed manufacturing overhead is expensed in year 1 as a period cost.
