Fixed costs are the same over the relevant range of expected production. Variable costs fluctuate in direct pro - portion to volume. You have seen how cost behavior influences measures of income, flex - ible budgeting, standard costing models, and so forth. Management must understand cost behavior to operate a successful business organization effectively. In this chapter, your knowledge of cost behavior will be extended to encompass techniques\ useful in studying a business’s break-even point and similar concepts. These techniques are com - monly referred to as cost–volume–profit analysis or just CVP. You will also apply your knowledge of cost behavior to understand alternative costing methods tha\ t are useful in managing business decisions. 5.1 Mixed Costs B efore diving into CVP and alternative costing models, one must give consideration to the prospect of a mixed cost. Mixed costs entail a fixed component and a variable component. They are actually quite common. If you have ever committed to a cell phone contract, it is very possible that you have some hands-on experience wit\ h mixed costs.

Your monthly cellular bill may include both fixed and variable amounts. P\ erhaps there is a fixed charge for basic monthly service and variable charges related to Internet access, texting, and so forth. Mixed costs change in response to fluctuations in volume, but not in a way that is immediately apparent. Before a manager can study the effects of volume fluctuation on a business, it is first necessary to develop a model that\ separates mixed costs into their fixed and variable components.

Assume that Charlie’s Restaurant receives a monthly electric bill. Charlie’s electricity use fluctuates significantly each month. The cause of the fluctuation relates mostly to seasonal differences in utility consumption, based on heating and air-conditioning needs. Charlie’s provides data about its monthly electric bill in Table 5.1. waL80281_05_c05_113-140.indd 2 9/25/12 1:03 PM CHAPTER 5 115 Section 5.1 Mixed Costs Table 5.1: Charlie’s electric bill data Total costKilowatts used January $1,95015,000 February 1,75013,000 March 1,65012,000 April 1,350 9,000 May 1,45010,000 June 1,75013,000 July 2,15017,000 August 2,05016,000 September 1,85014,000 October 1,350 9,000 November 1,55011,000 December 1,75013,000 At first glance, it may not be at all apparent how the total cost relates to the total usage.

However, a graphical representation of this cost is quite revealing. Exhibit 5.1 is a chart with the total cost indicated along the vertical axis and the total usage along the horizontal axis. From this chart, you are able to see that fixed cost is the same, at $450, no matter the electricity consumed. Variable cost is rising at $0.10 per kilowatt hour. Exhibit 5.1 KILOWATTS USED TOT AL ELECTRICITY COST Va riable cost area Fixed cost area 18,000 16,000 14,000 12,000 10,000 8,000 6,000 4,000 2,000 0 $2,500 $2,000 $1,500 $1,000 $500 $0 waL80281_05_c05_113-140.indd 3 9/25/12 1:03 PM CHAPTER 5 116 Section 5.1 Mixed Costs Perhaps you are able to “eyeball” the data in the table and make a determination\ of the fixed and variable portions in the electric bill. However, what if the data set is much larger and more cryptic? How can you estimate the fixed and variable amounts? This problem is frequently encountered because many expenses contain both fixed and variable compo- nents. A simple (and sometimes imprecise) approach is the high–low method. With this technique, the highest and lowest levels of activity are identified and the difference in cost is deemed to be representative of the variable portion. The variable portion is divided by the difference in activity/consumption between the high and low activity levels to\ find the variable cost per unit. The fixed cost can be calculated by subtract\ ing variable cost from total cost. In Table 5.2 are calculations of the fixed and variable costs for Exhibit 5.1, determined by using the high–low method.

Table 5.2: Fixed and variable costs for Charlie’s Restaurant Kilowatts Cost Highest level 17,000 $2,150 Lowest level 9,000 1,350 Difference 8,000 $800 Variable cost per unit $800/8,000 5 $0.10 High Low Total cost $2,150 $1,350 Less: Variable cost (kilowatts 3 $0.10) 1,700 900 Fixed cost $450 $450 Certainly, the high–low method is not the only technique that can be used to e\ stimate fixed and variable components. Also, if there are outlying data points (on the high or low end), the resulting estimates of fixed and variable components can be quite mislead\ ing.

When data are not as linear as presented in the illustration, more precise tools are needed to separate costs into fixed and variable components.

One such tool is regression analysis (also known as the method of least squares regression analysis), which defines a line that has a best fit to a set of data. The line is defined in terms of its intercept with the vertical axis and its slope. To better understand regression analy - sis, consider Exhibit 5.2 showing a line that intercepts the y axis at 2 and has a slope of 0.8. waL80281_05_c05_113-140.indd 4 9/25/12 1:03 PM CHAPTER 5 117 Section 5.1 Mixed Costs Exhibit 5.2 In the diagram, note that the line is rising consistently upward to the right as it moves out along the x axis. The rate of rise is called the slope of the line, and it is occur\ ring at the rate of 0.8 along the y axis for every 1 unit increase along the x axis. It is said that one picture is worth a thousand words, and the same can be true of some mathematical equations. You should be able to close your eyes and imagine the same line based on knowledge of its mathematical formula:

Y 5 2 1 0.8X where a is the intercept on the y axis, b is the slope of the line, and X is the position on the x axis.

This conventional mathematical formulation of a line can be translated t\ o a discussion of fixed and variable costs in an accounting context. In other words, the formula can also be used to describe a mixed cost that consists of $2 of fixed cost and an a\ dditional variable component of $0.80 per unit. For example, if five units were produced, total costs would be $6 (see the circle in Exhibit 5.2), consisting of $2 fixed and $4 variable (5 units 3 $0.80).

Given a large historical data set about a mixed cost over time, how can regression analysis be used to analyze the data and find the formula for the line that best \ passes through the data? In a precise context, regression provides a mathematical model that processes the data set to find a line where the cumulative sum of the squared distances between the points and the line is minimized (hence the name “least squares”). You might actually learn to do these calculations in an advanced statistics class. Fortunat\ ely, however, elec - tronic spreadsheets include built-in functions that do these calculations for you.\ Exhibit 5.3 is an example of a spreadsheet plotting hypothetical cost data against hypothetical production data for a series of years: 20 2 0 4 6 8 10 12 4681 012 X Run = 10 Rise = 8 Y SLOPE = 0.8 waL80281_05_c05_113-140.indd 5 9/25/12 1:03 PM CHAPTER 5 118 Section 5.2 Cost–Volume–Profit Analysis Exhibit 5.3 In the spreadsheet, column C includes annual production data, whereas column D identi- fies total cost. The formula included in cell C16 (=INTERCEPT(D5:D13,C5:C13)) serves to calculate the intercept for the cost plotted against the volume. The indicated value of approximately $250,000 suggests fixed costs of approximately that level for each year.

The slope reported in cell C17 (5SLOPE(D5:D13,C5:C13)) can be interpreted to mean that variable cost is $2.63 per unit of production. The accompanying graph shows the indi- vidual points and the resulting line defined by this formula:

Y 5 $250,044 1 $2.63X This line resulting under regression analysis produces the best fit line, such that the verti - cal distance, squared, between each point and the resulting line is minimized. This line is deemed to be the best fit line, and it gives the best indication of the \ fixed and variable costs over time. A simple approach to regression is to simply “eyeball the points” and draw a line through them. You would then estimate the slope and intercept of this estimated line.

This approach is not as precise as regression analysis, but it can get you in the right ball - park for a quick estimate.

5.2 Cost–Volume–Profit Analysis A good manager must understand an organization’s variable and fixed cost components.

That is why it is essential to perform analysis such as that just illust\ rated to discern the precise nature of a company’s cost behavior. Knowledge about the cost structure is essen - tial for cost–volume–profit (CVP) analysis. CVP is helpful in assessing the relationships between costs, business volume, and profitability. These relationships take into account variables pertaining to pricing, volume, variable and fixed costs, and p\ roduct mix. $0 $600,000 $500,000 $400,000 $300,000 $200,000 $100,000 20,000 40,000 60,000 80,000 TOT AL COST 100,000 120,000 Year Production Total cost 20X1 20 X2 20 X3 20 X4 20 X5 20 X6 20 X7 20 X8 20 X9 100,000 90,000 75,000 110,000 70,000 105,000 95,000 60,000 85,000 $500,000 $480,000 $465,000 $550,000 $440,000 $535,000 $485,000 $399,500 $475,000 Intercept (spreadsheet cell C16) = 250044.335 Slope (spreadsheet cell C17) = 2.631773399 waL80281_05_c05_113-140.indd 6 9/25/12 1:03 PM Column C Column D CHAPTER 5 119 Section 5.2 Cost–Volume–Profit Analysis The goal of CVP is to provide a foundation for pricing decisions, product offerings, and management of an organization’s cost structure. In the following discussion, you will learn how to calculate a company’s break-even point as well as the volume level neces- sary to achieve a targeted amount of income.

The core of CVP analysis is the contribution margin or revenues minus all variable expenses:

Contribution Margin 5 Revenues 2 Variable Expenses Some of these variable costs are product costs and some relate to selling and administra- tive activities. The contribution margin should not be confused with gross profit (revenues minus cost of sales). Gross profit would be calculated after deducting all manufacturing costs associated with sold units, whether fixed or variable. Furthermore, gross profit is calculated before considering selling, general, and administrative costs. Thus, the cont\ ribu - tion margin and gross profit are two entirely different concepts. The contribution margin is a calculated value for internal analysis, but it is ordinarily not reported to parties external to the firm.

Assume that Mustang Corporation manufactures and sells fishing boats. Each boat sells for $10,000, and variable manufacturing costs are $6,000 per boat. In addition, the boats are only sold through commissioned agents who receive $1,500 for each boat sold. Mus - tang’s per-unit contribution margin is $2,500 ($10,000 2 ($6,000 1 $1,500)). Mustang incurs $2,500,000 of fixed costs, no matter how many boats are produced and sold. The company must sell 1,000 units to break even, as shown in Table 5.3.

Table 5.3: Breaking even Total Per boat Ratio Sales (1,000 3 $10,000) $10,000,000 $10,000100% (or 1.00) Variable costs (1,000 3 $7,500) 7,500,000 7,500 75% (or 0.75) Contribution margin $ 2,500,000 $ 2,500 25% (or 0.25) Fixed costs 2,500,000 Net income $ 0 In reviewing Table 5.3, you likely noticed that the contribution margin can be reflected in the aggregate, on a per-unit basis, or on a ratio basis. The ratios may be expressed as percentages or fractional amounts (e.g., 50% or 0.50). These data were designed to reflect a break-even outcome of 1,000 units. In the following paragraphs, you will l\ earn how to determine, in advance, the sales that are necessary to break even. Before looking at those formulations, let’s first consider what would happen to Mustang if sa\ les were 1,500 units.

Logic suggests that the company will be profitable. If 1,000 units are first needed to break even, then selling an additional 500 units should produce profits equivalent to the added contribution on those 500 units (500 3 $2,500 5 $1,250,000). The calculations in Table 5.4 prove this logic: waL80281_05_c05_113-140.indd 7 9/25/12 1:03 PM CHAPTER 5 120 Section 5.2 Cost–V olume–Profit Analysis Table 5.4: Logic of being profitable Total Per boat Ratio Sales (1,500 3 $10,000) $15,000,000 $10,000100% (or 1.00) Variable costs (1,500 3 $7,500) 11,250,000 7,500 75% (or 0.75) Contribution margin $ 3,750,000 $ 2,500 25% (or 0.25) Fixed costs 2,500,000 Net income $ 1,250,000 The changes in volume only impacted the total column in Table 5.4. Volume changes do not change the per-unit or ratio effects. This will be important to remember in the ensuing formulas that you will learn for break-even calculations. Break-even analysis can also be presented in a graphical manner as in Exhibit 5.4. Exhibit 5.4 A break-even chart, such as the one shown for Mustang, is intended to allow the user to observe the unit sales volume (as revealed along the horizontal axis in Exhibit 5.4) that is necessary for a company to break even. In other words, it is the point where the amount of sales in dollars equals the total cost in dollars. Total sales are portrayed by the line starting at zero and sloping upward at $10,000 per unit. In contrast, total costs start at $2,500,000 (the amount of fixed costs) and rise more slowly at $7,500 per unit (the amount of variable cost per unit). TO TAL UNITS CVP ANALY SIS Variable cost area Pr ofit area Loss area Total cost line Break-ev en point Total sales line Fixed cost area 2,000 1,500 1,000 500 0 0 20,000,000 10,000,000 2,500,000 waL80281_05_c05_113-140.indd 8 9/25/12 1:03 PM CHAPTER 5 121 Section 5.2 Cost–V olume–Profit Analysis Some companies utilize graphs such as that shown in Exhibit 5.4 to keep \ an eye on their margin of safety. The margin of safety is simply the amount by which sales exceed the break-even sales level. If Mustang’s actual sales were $15,000,000, their margin of safety would be $5,000,000 ($15,000,000 2 $10,000,000 break-even sales). Operating leverage is a related CVP term that is often used. It refers to the amount of increase in income associ - ated with an increase in sales. This concept is based on the differences in slope between the total revenue line and the variable cost line; in essence, it reflects the contribution mar - gin rate. Some businesses refer to the process of evaluating margin of safety and operating leverage as tools in “sensitivity” or “scalability” analysis\ . Basically, it is perspective on how changes in volume impact changes in income.

The Algebra of Break-Even and Targeted Income Analysis The preceding graphical representation can be converted to algebraic formulas. Consider the following relationships:

Break-Even Sales 5 Total Variable Costs 1 Total Fixed Costs Mustang’s 10,000 units in sales to break even is confirmed via the following: (Units 3 $10,000) 5 (Units 3 $7,500) 1 $2,500,000 Solving: (Units 3 $10,000) 2 (Units 3 $7,500) 5 $2,500,000(Units 3 $2,500) 5 $2,500,000Units 5 1,000 The 1,000 units, at $10,000 each, translate into total sales of $10,000,\ 000. The preceding relationships can be algebraically modified to formulate a calculation of\ breakeven by reference to the contribution margin ratio: Break-Even Sales = Total Fixed Costs / Contribution Margin Ratio $10,000,000 5 $2,500,000/0.25 Utilization of this ratio-based approach is helpful for multiproduct companies as long as all products have a consistent contribution margin.

As yet another modification to the algebra, consider that total fixed co\ sts can simply be divided by the contribution margin per unit: Break-Even Point in Units = Total Fixed Costs / Contribution Margin Per Unit 1,000 Units 5 $2,500,000/$2,500 waL80281_05_c05_113-140.indd 9 9/25/12 1:03 PM CHAPTER 5 122 Section 5.2 Cost–V olume–Profit Analysis Of course, businesses are not in business just to break even. They likely have targeted income levels and desire to know the amount of sales that will be needed to reach those goals. The determination of sales necessary to achieve a targeted amount of income is a very easy modification of the break-even calculations. All that is required is to treat the desired income in a manner similar to the amount of fixed costs that must be covered by the margin:

Sales to Achieve Targeted Income 5 Total Variable Costs 1 Total Fixed Costs 1 Target Income If Mustang desired to earn $1,000,000 of income, the following calculations would be appropriate: (Units 3 $10,000) 5 (Units 3 $7,500) 1 $2,500,000 1 $1,000,000 Units 3 $2,500 5 $3,500,000 Units 5 1,400 If you want to know the dollar level of sales to achieve this targeted income, you could multiply the 1,400 units by the $10,000 selling price per unit, or $14,000,000 5 (Total Fixed Costs 1 Target Income) / Contribution Margin Ratio $14,000,000 5 $3,500,000/0.25 Influence of Taxes Taxes are a significant cost of doing business. Some taxes are fixed in amount, such as property taxes. They are easily factored into CVP by increasing the total fixed cost pool.

However, taxes based on income present a slight complication to CVP. Income taxes are nonexistent up to the break-even point (i.e., you do not pay income taxes until you turn profitable) and then kick in based on a predetermined rate. The effect of an income tax essentially means that you have two different contribution margin rates—one based on sales minus variable expenses (without taxes) up to the break-even point and another based on sales minus variable expense and income taxes once the break-even point is exceeded.

The preceding discussion points to the rather obvious need to modify the algebra associ - ated with profitability analysis. First, income taxes will not modify the break-even cal - culations. However, sales necessary to achieve target income level calculations must be amended. One simple way to perform this analysis is in two stages. The f\ irst stage is to calculate the break-even point. The second stage is to calculate the additional sales ne\ eded to reach the target income. In the second stage, it is important to remember that fixed costs have already been covered at the break-even point, but the contribution margin is reduced because of the income taxes.

To illustrate, assume the Go for Gold Mining faces the following facts:

Fixed costs $2,000,000 waL80281_05_c05_113-140.indd 10 9/25/12 1:03 PM CHAPTER 5 123 Section 5.2 Cost–Volume–Profit Analysis Variable mining costs $ 750 per ounce Income tax rate 50% If gold is selling for $1,500 per ounce (giving rise to a pretax contribution margin of 50%), and Go for Gold desires to reach an after-tax income level of $1,000,000, how much gold must be sold?

The first step is to calculate break-even sales: $2,000,000 (fixed costs)/0.50 contribution margin ratio 5 $4,000,000 in sales The second step is to calculate the additional sales to earn a $1,000,000 profit: $1,000,000 (target inc ome)/0.25 revised cont ribution margin rati o 5 $4,000,000 in sales. Note: 50% contributio n plus 50% tax on that same 50% gives us 75% in cont ribution margin plus t axes. Combining the sales to reach breakeven plus the additional sales to reach the target income level reveals that Go for Gold must sell $8,000,000 to achieve the desired income level. You likely noticed that the contribution margin in the second step was only 25% instead of 50%. The reason is that any profits had to be shared 50:50 with the government (given the assumed 50% income tax rate). This means that the company’s contribu\ tion was reduced in half for all sales above the break-even point!

Changing Costs Costs can naturally be expected to shift over time. These changes will i\ mpact the struc - tural relationships between fixed and variable components. Management must be able to contemplate how cost shifts will impact the business. For instance, an i\ ncrease in fixed costs, without a change in per-unit variable costs and revenues, will obviously increase the break-even point. The proper analysis for an increase in fixed cost requires that the new total fixed cost be divided by the contribution margin. Suppose Mustang’s total fixed costs increased from $2,500,000 to $3,000,000. What sales level is now necessary to break even? Recall that the break-even point in sales can be derived by dividing total fixed costs by the contribution margin ratio. Thus, the new calculation of breakeven is as follows:

$12,000,000 5 $3,000,000/0.25 The $500,000 additional fixed cost requires an additional $2,000,000 in sales. As you can see, the revisions in fixed costs are relatively simple to incorporate into the break-even framework with which you are already familiar. However, what about changes in variable costs? What if a new environmental regulation required that an additional $500 be spent on each boat to use a safer fiberglass handling process? Now, the contribution margin is only $2,000 per unit ($10,000 2 ($7,500 1 $500)). Assuming the added cost cannot be passed through, how will this impact the break-even point? The revised break-even point (let’s assume fixed costs are still $2,500,000 for this illustration) is now calculated as follows:\ $12,500,000 5 $2,500,000/0.20 waL80281_05_c05_113-140.indd 11 9/25/12 1:03 PM CHAPTER 5 124 Section 5.2 Cost–V olume–Profit Analysis Of course, a business sometimes must choose between adding either a fixe\ d or a vari - able cost. Suppose the per-unit increase in variable cost associated with a safer fiberglass handling process could be avoided by instead incurring a $500,000 increase in fixed cost.

If you review the two preceding examples, you can see that breakeven is lower with the added fixed cost, and you might jump to the conclusion that it would be \ the preferred option. However, if the business’s sales fail to reach even the break-even level, there is a point at which the added fixed cost would become disadvantageous. For ex\ ample, if sales reached only $8,000,000, Table 5.5 reveals that the loss is less for the case in which the increased fixed cost was avoided. Table 5.5: Loss is less With increased fixed cost Without increased fixed cost Sales $8,000,000 $8,000,000 Less: Fixed costs ($3,000,000) ($2,500,000) Less: Variable costs (800 , $7,500) ($6,000,000) Less: Variable costs (800 , $8,000) ($ 6,400,000) Net loss ($1,000,000)($ 900,000) Changing Revenues Changes in per-unit revenue, without changes in total fixed costs or per-unit variable cost, can sometimes cause dramatic impacts on firm profits. This is especially true for busi - nesses with a low variable cost structure. Consider the example in Table 5.6, in which firm profits are calculated before and after a $10 per-unit increase in selling price.

Table 5.6: Calculating profits Before price increase After price increase Sales (5,000 units) $500,000$550,000 Variable costs ($40 per unit) 200,000 200,000 Contribution margin $300,000 $350,000 Fixed costs 275,000 275,000 Net income $25,000 $75,000 Notice that the $10 (10%) increase in selling price caused a tripling of profits from $25,000 to $75,000. This simple illustration shows the importance of small adjus\ tments in selling prices. Of course, markets are at times very sensitive to pricing. Customers may not be willing to pay the added $10, which can cause a reduction in per-unit sales. Management must be very careful in setting its pricing policies. waL80281_05_c05_113-140.indd 12 9/25/12 1:03 PM CHAPTER 5 125 Section 5.3 CVP Assumptions Multiple Products Most businesses offer more than one product. Each product may have a different selling price, contribution margin, and contribution margin ratio. This has the potential to com- plicate CVP analysis. Now, knowledge is also required about the proportion of total sales attributable to each product.

To illustrate, assume that Infusion Technology sells hospital medication pumps and dis - posable cassettes that hold various medications. The pumps sell for $5,000 and have vari - able costs of $4,000. The contribution margin is therefore $1,000 per pump. The cassettes sell for $20 and have variable costs of $10, giving rise to a $10 per-unit contribution mar - gin. Infusion Technology sells 1,000 cassettes for each pump sold. How many pumps and cassettes must be sold to cover the business’s $1,100,000 of total fi\ xed costs? Consider that a product “unit” typically consists of one pump and 1,000 cassettes. T\ hus, the “unit” would have a contribution margin of $11,000, as shown in Table 5.7.

Table 5.7: Contribution margin Contribution margin Pump 1 item at $1,000 Cassette 1,000 items at $10 5 $10,000 “Unit contribution” $11,000 To recover $1,100,000 of fixed cost requires sales of 100 “units” ($1,100,000/$11,000). This is equivalent to selling 100 pumps and 100,000 cassettes. Total break-even sales equal $2,500,000 (($5,000 3 100 pumps) 1 ($20 3 100,000 cassettes)). This break-even sales level would shift dramatically if the product mix is not as projected. Pumps have a much lower contribution margin than cassettes, and increasing their sales (without a corresponding increase in the high-margin cassettes) would cause a dramatic shift in the break-even level of sales.

5.3 CVP Assump tions T he CVP techniques illustrated in this chapter are simply models of cost behavior.

Financial models are typically based on various assumptions. Violating an assump - tion can cause a model to produce misleading results. Therefore, it is very important for you to consider the assumptions of CVP in Table 5.8. waL80281_05_c05_113-140.indd 13 9/25/12 1:03 PM CHAPTER 5 126 Section 5.3 CVP Assumptions Table 5.8: Assumptions of CVP Inventory levelsConstant, with the number of units sold equaling the number of units produced. Fluctuations in inventory would result in a portion of the variable and fixed costs being transferred in and out of inventory rather than income. Identification of costs Costs can be clearly and reliably identified as fixed and variable in nature. Preservation of linearity Variable costs are constant per unit, and total fixed costs are stable and constant over the relevant range of activity. Revenues are constant per unit. Product mix ratios meet expectations Revenues are constant per unit, and multiple-product firms meet the expected product mix ratios. Direct Costing Now that you have examined the contribution margin and how it can be useful in corpo - rate analysis, it is time to expand upon the concept to see how it dovet\ ails with report - ing. Two general models can be used to measure and report income for a manufacturer.

One is absorption (or full) costing. It is the model with which you ar\ e currently familiar, and it is required for external reporting purposes. There is an alternative model, accept - able only for internal use, called direct (or variable) costing. Each has its advantages and disadvantages.

Absorption costing provided the basis for prior chapter illustrations. Under this tech - nique, all manufacturing costs are deemed to be product costs and are therefore included in inventory. When sold, the full cost of inventory is transferred to cost of goods sold. The result is that gross profit is reduced by all costs of manufacturing, including direct mate- rials, direct labor, and variable and fixed manufacturing overhead. Also recall that sell- ing, general, and administrative costs (SG&A) are classified as period expenses, whether fixed or variable in nature. Generally accepted accounting principles (GAAP) require this approach based on the premise that inventory should be measured and reported at its complete cost. There is obvious merit to this conclusion. A product could likely not be produced without a certain amount of fixed manufacturing overhead, and it seems inap - propriate to exclude such costs as one attempts to report on their manufacturing profits.

Variable (direct) costing only assigns variable product costs to inventory and cost of goods sold. Thus, product costs are deemed to include direct materials, direct labor, and variable manufacturing overhead. The fixed manufacturing overhead is regarded as a period cost. Table 5.9 highlights the difference in perspective between absorption and variable costing. waL80281_05_c05_113-140.indd 14 9/25/12 1:03 PM CHAPTER 5 127 Section 5.3 CVP Assumptions Table 5.9: Absorption versus variable costing Absorption costingVariable costing Product cost Period costProduct cost Period cost Direct material ✔✔ Direct labor ✔✔ Variable manufacturing overhead ✔✔ Fixed manufacturing overhead ✔ ✔ Variable SG&A ✔✔ Fixed SG&A ✔✔ In light of GAAP’s requirement for absorption costing, and the associated arguments in support of this view, why might a company opt for variable costing for internal use?

Regardless of the claims in support of absorption costing, it does suffer from some limita - tions that can impede appropriate management decisions. Absorption costing does not necessarily provide the best signals about product pricing, whether to continue to produce a product, whether to accept a special order, and similar decisions. With variable costing, fixed manufacturing costs are shifted from product costs to period costs because they will be incurred no matter the level of production. Simply stated, in many cases, a company should continue to produce a product that has a positive contribution margin, even if the overall results still appear to be producing a loss; the loss would be larger if the fixed costs were incurred and nothing was produced. Absorption costing does not illuminate this reality in a way that enables good decisions. Numerous similar situations can arise. This is a very important concept and bears much deeper analysis via a series of \ examples.

Assume that Home Pride produces 500,000 loaves of bread per month, and per-unit costs are $0.45 for direct material, $0.30 for direct labor, and $0.25 for variable factory over - head. Total fixed factory overhead amounts to $250,000. Under absorption costing, a loaf of bread costs $1.50 to produce. This consists of variable costs ($0.45 1 $0.30 1 $0.25 5 $1) and fixed costs ($250,000/500,000 loaves 5 $0.50). Under variable costing, the prod- uct cost includes just the $1.00 of variable manufacturing components. I\ f Home Pride is approached by Super Grocery to produce a private-label bread product, and Super Gro - cery is willing to pay $1.25 per loaf, should Home Pride accept the deal\ ? Home Pride has evaluated the transaction and concluded that it will not result in any added variable or fixed SG&A costs, and it will not cause a reduction in sales of its own bread products.

With absorption costing, it appears that the offer should be rejected. Why sell something for $1.25 when it costs $1.50 to produce? This seems obviously irrational. Conversely, vari - able costing suggests that a profit of $0.25 per loaf will result by accepting Super Grocery’s offer. Which decision is right? Management may well decide to accept the offer to enhance profits. It is important to recall that no other costs will be incurred. Reliance on absorption costing for decision making could have resulted in this opportunity having been missed.

Very likely, you are now beginning to understand why some companies prefer a variable costing structure for internal measurement and decision-making purposes. waL80281_05_c05_113-140.indd 15 9/25/12 1:03 PM CHAPTER 5 128 Section 5.3 CVP Assumptions Comprehensive Income Statements Under Variable and Absorption Costing The preceding discussion focused on the general structure of income measurement under absorption and variable costing. The Home Pride example further assumed \ that SG&A was unaffected by the decision to sell to Super Grocery. That assumption would often not be valid. Variable SG&A typically increases along with rising sales, and this factor will be reflected in a variable costing income statement. Consider the following \ income statements for Garcia Company. Garcia does not maintain inventory, and it sells all that is produced each period. As a result, total income is the same, whether measured under absorption or variable costing. The difference, therefore, is only in how the data are pre- sented. Absorption costing will focus on an intermediate subtotal relating to gross profit.

This is a different focus than with variable costing, in which the emphasis is on contri\ bu - tion margins. Begin by closely examining the absorption costing income statement\ shown in Exhibit 5.5, and then review the additional commentary that follows. Exhibit 5.5 Under absorption costing, assume the $500,000 cost of goods sold consists of direct mate - rials ($150,000), direct labor ($200,000), and variable ($50,000) and fixed manufacturing\ overhead ($100,000). Gross profit is reduced by SG&A, which is assumed to be $125,000 variable and $75,000 fixed. When these same factors are rearranged and presented as in a variable costing income statement format, you will first notice that all variable costs are subtracted from sales to arrive at the contribution margin. Garcia Company further divides the contribution margin between the manufacturing margin and the overall mar - gin, after subtracting variable SG&A (Exhibit 5.6). Sales Cost of goods sold Gross profit Less: Variable SG&A Fixed SG&A Net income $ 125,000 75,000 $1,000,000 500,000 $ 500,000 200,000 $ 300,000 GARCIA COMPANY Absorption Costing Income Statement For the Year Ending December 31, 20XX waL80281_05_c05_113-140.indd 16 9/25/12 1:03 PM CHAPTER 5 129 Section 5.3 CVP Assumptions Exhibit 5.6 Fluctuating Inventory You may be wondering what happens if inventory levels fluctuate. With absorption cost - ing, inventory will carry all manufacturing costs, whereas only variable manufacturing costs are assigned to inventory with variable costing. Generalizing, therefore, inventory is measured at a higher value with absorption costing; in other words, certain costs (a por - tion of the fixed manufacturing overhead) are placed in inventory that would otherwise be expensed immediately under variable costing. This means that income i\ s higher with absorption costing in those periods during which inventory levels are increasing. Let’s revisit Garcia Company, this time assuming that sales are 10% less, and the unsold units become part of ending inventory. The income statements (Exhibits 5.7 and 5.8) show how income is higher under absorption costing by $10,000. This is exactly as expected. In other words, 10% of the $100,000 of fixed manufacturing overhead is assigned to inventory under absorption costing versus what is expensed under variable costing.\ Sales Less: Variable product costs Manufacturing margin Less: Variable SG&A Contribution margin Less: Fixed factory cost Fixed SG&A Net income $ 100,000 75,000 $1,000,000 400,000 $ 600,000 125,000 $ 475,000 175,000 $ 300,000 GARCIA COMPANY Variable Costing Income Statement For the Year Ending December 31, 20XX waL80281_05_c05_113-140.indd 17 9/25/12 1:03 PM CHAPTER 5 130 Section 5.4 Evaluating Residual Income Exhibit 5.7 Exhibit 5.8 5.4 Evaluating Residual Income C omparing income measures under absorption and variable costing provides helpful clues to guide correct managerial decisions. However, these measures are not a pana- cea for management. Additional economic facets must be considered. For instance, neither measure adjusts income for the embedded amount of capital that must be deploye\ d to gen - erate the reported income numbers. In other words, the level of stockholder investments is not factored into the basic income calculations. If two businesses each generate i\ ncome of $1,000,000 but one of the businesses has stockholder investments of $5,000,000 and the other has stockholder investments of $10,000,000, it is apparent that the former business Sales Less: Variable product costs Manufacturing margin Less: Variable SG&A Contribution margin Less: Fixed factory cost Fixed SG&A Net income $ 100,000 75,000 $ 900,000 360,000 $ 540,000 112,500 $ 427,500 175,000 $ 252,500 GARCIA COMPANY Variable Costing Income Statement For the Year Ending December 31, 20XX Sales Cost of goods sold Gross profit Less: Variable SG&A Fixed SG&A Net income $ 112,500 75,000 $ 900,000 450,000 $ 450,000 187,500 $ 262,500 GARCIA COMPANY Absorption Costing Income Statement For the Year Ending December 31, 20XX waL80281_05_c05_113-140.indd 18 9/25/12 1:03 PM CHAPTER 5 131 Section 5.4 Evaluating Residual Income is generating a better rate of return on the amount of invested capital. Thus, not only is it important that a business have profitable operations to maintain long-run economic viabil- ity but also it must generate returns that are sufficient to justify the investment. In a later chapter, you will study many capital budgeting tools that aid in these evaluati\ ons.

However, you are already in a position to consider the concept of residual income. Like vari - able costing, residual income is not a GAAP-based measure. Instead, it is another internal financial assessment technique. Residual income provides a scale of business success or fail- ure after adjusting for the presumed cost of capital. The cost of capital is the theoretical rate that funds could earn if invested in alternative use. The cost of capita\ l varies by firm and is based on general economic conditions. Although there are variations in the way in which residual income could be measured, one general approach is based on this formulation:

Residual Income 5 Operating Income 2 (Operating Assets 3 Cost of Capital) To see how residual income can be used for business assessments, begin by looking at the data for two separate business segments in Table 5.10.

Table 5.10: Data for two business segments Segment A Segment B Operating income $ 250,000 $500,000 Less: Cost of capital Segment A capital $3,000,000 3 5% cost of capital (150,000) Segment B capital $9,000,000 3 5% cost of capital (450,000) Residual income $ 100,000 $ 50,000 At first glance, it appears that Segment B is more successful because its operating income is twice that of Segment A. However, Segment B has much more capital invested in opera - tions ($9,000,000 for B vs. $3,000,000 for A). Assuming a 5% cost of capital, Segment A’s residual income is twice that of Segment B. This information casts the relative success of the two divisions in a completely different light. Thus, residual income can be a powerful tool for identifying and ranking the performance of segments, products, and other com - ponents of business activity.

As with most analysis techniques, great care must be taken in interpreting residual income.

Conclusions can be impacted by the assumption about the cost of capital and different rank - ings achieved by revisions in interest rates. In addition, management needs to understand the accounting principles that were used to measure operating income. For example, a unit may be spending heavily on developmental costs. Were these costs expensed? If so, then near-term income could be negatively impacted. In the long term, those same \ costs (having already been expensed) would be excluded from the calculation of invested capital and per - haps inflate the residual income in the latter stages of a project. Thus, management needs to be very careful in interpreting residual income. Nevertheless, when used appropriately, the technique is highly valuable in helping a business identify and rank\ products, segments, and business activities. It is crucial that business decisions about which products and ser - vices to offer, or cease to offer, be made with deliberate care and attention to detail. waL80281_05_c05_113-140.indd 19 9/25/12 1:03 PM CHAPTER 5 132 Concept Check Concept Check The five questions that follow relate to several issues raised in the chapter.
