CHAPTER 8 Absorption and Variable Costing

1 CHAPTER 8 Absorption and Variable Costing ANSWERS TO REVIEW QUESTIONS 8-1 Under absorption costing, fixed manufacturing-overhead costs are assigned to units of product as product costs. Under variable costing, fixed manufacturing-overhead costs are not assigned to units of product as product costs; rather they are treated as period costs and expensed during the period in which they are incurred. 8-2 Timing is the key in distinguishing between absorption and variable costing. All manufacturing costs will ultimately be expensed under either absorption costing or variable costing. The difference between the two methods lies in the time period during which fixed manufacturing-overhead costs are expensed. Under variable costing, the fixed manufacturing-overhead costs are expensed during the period in which they are incurred. Under absorption costing, fixed manufacturing-overhead costs are held in inventory as product costs until the period during which the units are sold. Then those costs flow into cost-of-goods-sold expense. 8-3 The term direct costing is a misnomer. Variable costing is a better term for this product-costing method. Under variable costing, the variable costs of direct material, direct labor, and variable overhead are treated as product costs. Fixed manufacturing-overhead costs are not treated as product costs. Thus, the important characteristic of a cost that determines whether it is treated as a product cost under variable costing is its cost behavior. Direct costing is a misnomer because variableoverhead costs are not direct costs, but they are treated as product costs under the variable-costing method. 8-4 When inventory increases, the income reported under absorption costing will be greater than the income reported under variable costing. This difference results from the fact that under absorption costing, some of the fixed manufacturing costs incurred during the period will not be expensed. In contrast, under variable costing all of the fixed manufacturing costs incurred during the period will be expensed during that period. 8-5 Many managers prefer variable costing over absorption costing because income statements prepared under variable costing more closely reflect operations. For example, when sales increase, other things being equal, income will also increase under variable costing. Under absorption costing, however, income will not necessarily increase when sales increase. Managerial Accounting, 9/e Global Edition 8-1

2 8-6 Under absorption costing, all manufacturing-overhead costs (including fixed costs) are assigned to units of product as product costs. Under variable costing, fixed manufacturing-overhead costs are not assigned to units of product as product costs; rather they are treated as period costs and expensed during the period in which they are incurred. Under throughput costing, only the unit-level spending for direct costs is assigned as a product cost. 8-7 Some managerial accountants believe that absorption costing may provide an incentive for managers to overproduce inventory so that the fixed manufacturing overhead costs may be spread over a larger number of product units, thereby lowering the reported product cost per unit. Throughput costing avoids this potential problem by not assigning fixed manufacturing overhead as a product cost. 8-8 Variable and absorption costing will not result in significantly different income measures in a JIT setting. Under JIT inventory and production management, inventories are minimal and as a result inventory changes are also minimal. Variable and absorption costing result in significantly different income measures only when inventory changes significantly from period to period. 8-9 Many managers prefer absorption-costing data for cost-based pricing decisions. They argue that fixed manufacturing overhead is a necessary cost of production. To exclude this fixed cost from the inventoried cost of a product, as is done under variable costing, is to understate the cost of the product. This, in turn, could lead to setting cost-based prices too low Proponents of variable costing argue that a product s variable cost provides a better basis for the pricing decision. They point out that any price above a product s variable cost makes a positive contribution toward covering fixed cost and profit Variable costing is consistent with cost-volume-profit analysis because it properly reflects the cost behavior of variable and fixed costs. Only variable manufacturing costs are treated as inventoriable product costs. Fixed manufacturing costs are recorded as a lump sum and expensed during the period incurred. CVP analysis also properly maintains the cost-behavior distinction between variable and fixed costs. In contrast, absorption costing is inconsistent with CVP analysis, because fixed overhead is applied to manufactured goods as a product cost on a per-unit basis. 8-2 Solutions Manual

3 8-12 An asset is a thing of value owned by the organization with future service potential. By accounting convention, assets are valued at their cost. Since fixed costs comprise part of the cost of production, advocates of absorption costing argue that inventory (an asset) should be valued at its full (absorption) cost of production. Moreover, they argue that these costs have future service potential since the inventory can be sold in the future to generate sales revenue. Proponents of variable costing argue that the fixed-cost component of a product s absorption-costing value has no future service potential. Their reasoning is that the fixed manufacturing-overhead costs during the current period will not prevent these costs from having to be incurred again next period. Fixed-overhead costs will be incurred every period, regardless of production levels. In contrast, the incurrence of variable costs in manufacturing a product does allow the firm to avoid incurring these costs again. Managerial Accounting, 9/e Global Edition 8-3

Variable costing is more compatible with the cost-volume-profit chart, because it maintains the distinction between fixed and variable costs as does CVP analysis. Absorption costing, in contrast, does not maintain the separation of fixed and variable costs. Fixed costs are unitized in the fixed overhead rate and inventoried as product costs along with variable manufacturing costs. EXERCISE 8-19 (10 MINUTES) 1.

11 EXERCISE 8-20 (30 MINUTES) The specifics of the answer will vary, depending on the company and product selected. However, the relative merits of absorption, variable and throughput costing as the basis for pricing decisions are generally the same, regardless of the company and product. Many managers prefer absorption-costing data for cost-based pricing decisions. They argue that fixed manufacturing overhead is a necessary cost of production. To exclude this fixed cost from the inventoried cost of a product, as is done under variable costing, is to understate the cost of the product. This, in turn, could lead to setting cost-based prices too low. Proponents of variable costing argue that a product s variable cost provides a better basis for the pricing decision. They point out that any price above a product s variable cost makes a positive contribution toward covering fixed cost and profit. Proponents of throughput costing take the variable-costing argument a step further and argue that a product s throughput cost provides the best basis for a cost-based pricing decision. They argue that any price above a product s unit-level spending for direct costs (e.g., throughput costs) makes a positive contribution toward covering fixed cost and profit.

Delizioso S.p.A. produced 150,000 units (i.e., containers) and sold 130,000, which leaves an ending finished-goods inventory of 20,000 units. Because only direct material qualifies as a throughput cost, the cost of the ending inventory is $120,000 (20,000 containers x $6). 2. DELIZIOSO S.P.A.

The cost of a unit differs and depends on whether a firm uses absorption costing or throughput costing. With absorption costing, the product cost consists of four elements: direct material, direct labor, variable manufacturing overhead, and fixed manufacturing overhead. Throughput costing, on the other hand, assigns only the unit-level spending for direct costs (in this case, direct material) as the cost of a product. 4.

23 PROBLEM 8-26 (CONTINUED) 3. For throughput costing: Some managerial accountants believe that absorption costing may provide an incentive for managers to overproduce inventory so that the fixed manufacturing overhead costs may be spread over a larger number of product units, thereby lowering the reported product cost per unit. Throughput costing avoids this potential problem by not assigning fixed manufacturing overhead as a product cost. Against throughput costing: Many managers prefer absorption-costing data for cost-based pricing decisions. They argue that fixed manufacturing overhead is a necessary cost of production. To exclude this fixed cost from the inventoried cost of a product, as is done under throughput (and variable) costing, is to understate the cost of the product. This, in turn, could lead to setting cost-based prices too low. Managerial Accounting, 9/e Global Edition 8-23

24 PROBLEM 8-27 (45 MINUTES) 1. Reported income will be lower under variable costing, because inventory is expected to increase by 1,000 units during the year. (Twenty thousand units will be produced in the last two months, but 19,000 units will be sold.) 2. a. Variable costing: Total contribution during first 10 months is equal to the fixed costs plus profit for that period. Fixed costs during first 10 months... $2,000,000 Profit during first 10 months ,000 Total contribution margin... $2,200,000 Contribution margin per unit $2,200, ,000 $22 per unit Projected total sales for the year are 119,000 units (100,000 in first 10 months plus 19,000 units in last 2 months). We can compute projected income for the year as follows: Projected total contribution margin ($22 119,000)... $2,618,000 Projected fixed costs ($200,000 12)... 2,400,000 Projected income... $ 218,000 The operating income projected for the year under variable costing is $218,000. Note: The problem states that the prior period s cost rates are the same as those of the current period. Absorption costing: The gross margin for the first 10 months is $200,000. Notice that income and gross margin are the same, since there are no selling or administrative expenses. Therefore, during the first 10 months: Gross margin per unit $200, ,000 units $2 per unit 8-24 Solutions Manual

25 PROBLEM 8-27 (CONTINUED) Projected sales for the year are 119,000 units, so we can compute projected income for the year as follows: Projected gross margin ($2 119,000)... $238,000 There are no selling and administrative costs, so projected operating income for the year under absorption costing is also $238,000. Check: Our conclusions can be checked by noting the following relationship: Reportedincome under reportedincome under variable costing absorptioncosting increase in inventory fixed-overhead rate 1,000 units $20 per unit $20,000 Therefore, reported income will be $20,000 lower under variable costing than under absorption costing. Managerial Accounting, 9/e Global Edition 8-25

26 PROBLEM 8-27 (CONTINUED) 3. Advantages and disadvantages of absorption and variable costing: (a) Pricing decisions: Many managers prefer to use absorption-costing data in costbased pricing decisions. They argue that fixed manufacturing overhead is a necessary cost incurred in the production process. To exclude this fixed cost from the inventoried cost of a product, as is done under variable costing, is to understate the cost of the product. For this reason, most companies that use cost-based pricing base their prices on absorption-costing data. Proponents of variable costing argue that a product s variable cost provides a better basis for pricing decisions. They point out that any price above a product s variable cost makes a positive contribution to covering fixed cost and profit. (b) Definition of an asset: Another controversy about absorption and variable costing hinges on the definition of an asset. An asset is a thing of value owned by the organization with future service potential. By accounting convention, assets are valued at their cost. Since fixed costs comprise part of the cost of production, advocates of absorption costing argue that inventory (an asset) should be valued at its full (absorption) cost of production. Moreover, they argue that these costs have future service potential since the inventory can be sold in the future to generate sales revenue. Proponents of variable costing argue that the fixed-cost component of a product s absorption-costing value has no future service potential. Their reasoning is that the fixed manufacturing-overhead costs during the current period will not prevent these costs from having to be incurred again next period. Fixed-overhead costs will be incurred every period, regardless of production levels. In contrast, the incurrence of variable costs in manufacturing a product does allow the firm to avoid incurring these costs again. (c) Cost-volume-profit analysis: Some managers find the inconsistency between absorption costing and CVP analysis troubling enough to warrant using variable costing for internal income reporting. Variable costing dovetails much more closely than absorption costing with any operational analyses that require a separation between fixed and variable costs. (d) External reporting: For external reporting purposes, generally accepted accounting principles require that income reporting be based on absorption costing Solutions Manual

In year 4, the difference in reported operating income will be $100,000, calculated as follows: Change in inventory (in units) Predetermined fixed overhead rate (10,000) $10 $(100,000) Income reported under absorption costing will be lower, because inventory will decline during year 4. b. Over the four-year period, the total of all reported operating income will be the same under absorption and variable costing. This result will occur because inventory does not change over the four-year period. It starts out at zero on January 1 of year 1, and it ends up at zero on December 31 of year 4.
