Chapter 11Lecture NotesChapter theme: Managers in large organizations have to Array delegate some decisions to those who are at lower levels inthe organization. This chapter explains how responsibilityaccounting systems, return on investment (ROI),residual income, operating performance measures, andthe balanced scorecard are used to help controldecentralized organizations.I.Decentralization in organizationsA. A decentralized organization does not confinedecision-making authority to a few top executives;rather, decision-making authority is spreadthroughout the organization. The advantages anddisadvantages of decentralization are as follows:i.Advantages of decentralization1.It enables top management to concentrate onstrategy, higher-level decision making, andcoordinating activities.2.It acknowledges that lower-level managershave more detailed information about localconditions that enable them to make betteroperational decisions.3.It enables lower-level managers to quicklyrespond to customers.4.It provides lower-level managers with thedecision-making experience they will needwhen promoted to higher level positions.5. It often increases motivation , resulting in increased job satisfaction and retention, as well as improved performance.ii. Disadvantages of decentralization1. Lower-level managers may make decisionswithout fully understanding the “big picture.”2. There may be a lack of coordination amongautonomous managers.a. The balanced scorecard can help reducethis problem by communicating acompany’s strategy throughout theorganization.3. Lower-level managers may have objectivesthat differ from those of the entireorganization.a. This problem can be reduced by designingperformance evaluation systems thatmotivate managers to make decisions thatare in the best interests of the company.4. It may be difficult to effectively spreadinnovative ideas in a strongly decentralizedorganization.II. Responsibility accountingA. Responsibility accounting systems link lower-levelmanagers’ decision -making authority withaccountability for the outcomes of those decisions.The term responsibility center is used for any part of an organization whose manager has control over, and is accountable for cost, profit, or investments. Thethree primary types of responsibility centers are cost centers, profit centers, and investment centers.i.Cost center1.The manager of a cost center hascontrol overcosts, but not over revenue or investment funds.a.Service departments such as accounting,general administration, legal, and personnelare usually classified as cost centers, as aremanufacturing facilities.b.Standard cost variances and flexiblebudget variances, such as those discussedin Chapters 10 and 11, are often used toevaluate cost center performance.ii.Profit center1.The manager of a profit center has control overboth costs and revenue.a.Profit center managers are often evaluatedby comparing actual profit to targeted orbudgeted profit.iii.I nvestment center1.The manager of an investment center hascontrol over cost, revenue, and investmentsin operating assets.b.Investment center managers are usuallyevaluated using return on investment (ROI)or residual income, as discussed later in thischapter.III. Evaluating investment center performance – return on investmentLearning Objective 1: Compute return on investment Array (ROI) and show how changes in sales, expenses, andassets affect ROI.A. Key concepts/definitionsi. Investment center performance is often evaluatedusing a measure called return on investment(ROI), which is defined as follows:Net operating incomeROIAverage operating assetsii. Net operating income is income before taxes and is sometimes referred to as EBIT (earnings beforeinterest and taxes). Operating assets include cash,accounts receivable, inventory, plant andequipment, and all other assets held for operatingpurposes.1. Net operating income is used in the numeratorbecause the denominator consists only ofoperating assets.2. The operating asset base used in the formula istypically computed as the average of the assetsbetween the beginning and the end of the year.iii. N et book value versus gross cost1. Most companies use thenet book value (i.e.,acquisition cost less accumulated depreciation)of depreciable assets to calculate averageoperating assets.a. With this approach, ROI mechanicallyincreases over time as the accumulateddepreciation increases. Replacing a fully-depreciated asset with a new asset willdecrease ROI.2. An alternative to net book value is the grosscost of the asset, which ignores accumulateddepreciation.a. With this approach, ROI does not growautomatically over time, rather it staysconstant. Replacing a fully-depreciatedasset does not adversely affect ROI.B. Understanding ROIi. Du Pont pioneered the use of ROI and recognizedthe importance of looking at the components ofROI, namely margin and turnover.1. Margin is computed as shown and is improvedby increasing unit sales, increasing sellingprices, or reducing operating expenses. Thelower the operating expenses per dollar of sales,the higher the margin earned.2. Turnover is computed as shown. It incorporates a crucial area of a manager’s responsibility – the investment in operating assets. Excessive funds tied up in operating assets depress turnover and lower ROI.Helpful Hint: Emphasize that both margin and turnover affect profitability. As an example, ask students tocompare the margins and turnovers of grocery stores to jewelry stores. In equilibrium, every industry should have roughly the same ROI. Groceries, because of their short shelf life, have high turnovers relative to fine jewelry. If the ROIs are to be comparable in grocery stores and in jewelry stores, the margins would have to be higher in jewelry stores.ii. To illustrate how to increase ROI, assume that Regal Company reports the results shown:1. Given this information, its current ROI is 15%.2. Suppose that Regal’s manager invests in a $30,000 piece of equipment that increases sales by $35,000 while increasing operating expenses by $15,000. a. In this case, the ROI increases from 15% to 21.8%.C. Criticisms of ROIi. Just telling managers to increase ROI may not beenough. Managers may not know how toincrease ROI in a manner that is consistent with the company’s strategy.1. This is why ROI is best used as part of abalanced scorecard.ii. A manager who takes over a business segment typically inherits many committed costs over which the manager has no control. This may make it difficult to assess this manager relative to other managers.iii. A manager who is evaluated based on ROI may reject investment opportunities that areprofitable for the whole company but that would have a negative impact on the manager’sperformance evaluation.Helpful Hint: When discussing the criticisms of ROI and other measures of profitability, ask students to play the role of a manager who anticipates a short tenure. This manager will want to increase ROI as quickly as possible. Ask students to list the activities that could be undertaken to increase ROI that, in reality, would hurt the company as a whole.IV. Residual incomeLearning Objective 2: Compute residual income and understand its strengths and weaknesses.A. Defining residual incomei. Residual income is the net operating income that an investment center earns above the minimum required return on its assets .B. Calculating residual incomei. The equation for computing residual income is asshown. Notice: 1. This computationdiffers from ROI. ROI measures net operating income earned relativeto the investment in average operating assets. Residual income measures net operating income earned less the minimum required return on average operating assets. ii. Zepher, Inc. - an example1. Assume the information as given for a division of Zepher, Inc.2. The residual income ($10,000) is computed by subtracting the minimum required return ($20,000) from the actual income ($30,000).C.Motivation and residual income i. The residual income approach encourages managers to make investments that are profitable for the entire company but that would be rejected by managers who are evaluated using the ROI formula. More specifically:1. It motivates managers to pursue investmentswhere the ROI associated with thoseinvestments exceeds the company’s minimumrequired return but is less than the ROI beingearned by the managers.Quick Check – ROI versus residual incomeD.Divisional comparison and residual income i.The residual income approach has one majordisadvantage. It cannot be used to compare the performance of divisions of different sizes.ii. Zepher, Inc. – continued1. Recall that the Retail Division of Zepher hadaverage operating assets of $100,000, aminimum required rate of return of 20%, netoperating income of $30,000, and residualincome of $10,000.2. Assume that the Wholesale Division of Zepherhad average operating assets of $1,000,000, aminimum required rate of return of 20%, netoperating income of $220,000, and residualincome of $20,000.3. The residual income numbers suggest that the Wholesale Division outperformed the Retail Division because its residual income is $10,000 higher. However: a. The Retail Division earned an ROI of30% compared to an ROI of 22% forthe Wholesale Division. TheWholesale Division’s residual incomeis larger than the Retail Divisionsimply because it is a bigger division .V.Operating performance measuresLearning Objective 3: Compute throughput time,delivery cycle time, and manufacturing cycle efficiency (MCE).A. Key definitions/conceptsi. Throughput (manufacturing cycle) time is theelapsed time from when production is started until finished goods are shipped to customers.1. This includes process time, inspection time, move time, and queue time . Process time is the only value-added activity of the fourmentioned.ii. Delivery cycle time is the elapsed time from whena customer order is received until the finished goods are shipped.iii. Manufacturing cycle efficiency (MCE) iscomputed by dividing value-added time by throughput time.1. The goal is to increase this measure.2. Any non-value-added time results in an MCE of less than 1.0.Quick Check – internal business process measures VI. Balanced scorecardLearning Objective 4: Understand how to construct and use a balanced scorecard.A. Key conceptsi. A balanced scorecard consists of an integratedset of performance measures that are derived from and support a company’s strategy. Importantly, the measures included in a company’s balanced scorecard are unique to its specific strategy . ii. The balanced scorecard enables top managementto translate its strategy into four groups of performance measures – financial, customer, internal business process, and learning and growth − that employees can understand and influence.1.The premise of these four groups of measuresis that learning is necessary to improveinternal business processes, which in turnimproves the level of customer satisfaction, which in turn improves financial results.a.Note the emphasis on improvement, notjust attaining some specific objective.iii.The balanced scorecard relies onnon-financial measures in addition to financial measures fortwo reasons:1.Financial measures are lag indicators thatsummarize the results of past actions. Non-financial measures are leading indicators offuture financial performance.2.Top managers are ordinarily responsible forfinancial performance measures – not lowerlevel managers. Non-financial measures aremore likely to be understood and controlledby lower level managers.iv.While the entire organization has an overall balanced scorecard, each responsible individualshould have his or her own personal scorecard as well.1.A personal scorecard should contain measuresthat can be influenced by the individual beingevaluated and that support the measures in theoverall balanced scorecard.v. A balanced scorecard, whether for an individualor the company as a whole, should have measures that are linked together on a cause-and-effect basis .1. Each link can be read as a hypothesis in the form “If we improve this performance measure, then this other performance measure shouldalso improve.”2. In essence, the balanced scorecard lays out a theory of how a company can take concrete actions to attain desired outcomes. If the theory proves false or the company alters its strategy, the measures within the scorecard are subject to change .vi. Incentive compensation for employeesprobably should be linked to balanced scorecard performance measures .1. However, this should only be done after the organization has been successfully managed with the scorecard for some time – perhaps a year or more . Managers must be confident that the measures are reliable, not easilymanipulated, and understandable by those being evaluated with them.B. The balanced scorecard – an example i. Assume that Jaguar pursues a strategy as shown on this slide. Examples of measures that Jaguar might select with their corresponding cause-and-effect linkages include:1. If “employee skills in installing options ” increases, then the “number of options available ” should increase and the “time to install an option ” should decrease.2. If the “number of options available ” increases and the “time to install an option” decreases, then “customer surveys: satisfaction with options available” should increase.3. If the “customer surveys: satisfaction with options available ” increases, then the “number of cars sold ” should increase.4. If the “time to install an option ” decreases and the “customer surveys: satisfaction with options available ” increases, then the “contribution margin per car ” should increase.5. If the “number of cars sold ” and the “contribution margin per car ” increase, then the “profit ” should incr ease.。

Chapter 6Lecture NotesChapter theme: Two general approaches are used for valuing inventories and cost of goods sold. One approach, called absorption costing , is generally used for external reporting purposes. The other approach, called variable costing , is preferred by some managers for internal decision making and must be used when an income statement is prepared in the contribution format . This chapter shows how these two methods differ from each other. It also explains how to create segmented contribution format income statements.I. Overview of variable and absorption costingLearning Objective 1: Explain how variable costing differs from absorption costing and compute unit product costsunder each method.Three simplifying assumptions are made in this chapter:i. Normal costing (rather than actual costing) is used (i.e., predetermined overhead rates are used to applyoverhead costs to product.ii. The actual number of units produced is used as theallocation base for assigning actual fixed manufacturingoverhead costs to products.iii. V ariable manufacturing costs per unit and the totalfixed manufacturing overhead cost per period remainconstant.2 3B. Variable costing treats only those costs of production that vary with output as product costs. This approach dovetails with the contribution approach income statement andsupports CVP analysis because of its emphasis onseparating variable and fixed costs.i. The cost of a unit of product consists of directmaterials, direct labor, and variable overhead .Helpful Hint: For simplicity, nearly all examples, exhibits, problems, and exercises in this chapter treat direct labor as a variable cost. However, students should be reminded that labor is essentially a fixed cost in some companies. This is a growing phenomenon as pointed out in earlier chapters.Under variable costing, direct labor would not be included in product costs when it is a fixed cost. This point is reinforced in the discussion on theory of constraints at the end of the chapter.ii. Fixed manufacturing overhead and both variable andfixed selling and administrative expenses are treated asperiod costs and deducted from revenue as incurred.Helpful Hint: Emphasize that the only difference between variable and absorption costing is in how the two methods treat fixed manufacturing overhead costs. Also, emphasize that under both methods, selling and administrative costs are period costs and are not product costs.C. Absorption costing treats all costs of production as product costs, regardless of whether they are variable or fixed. Since no distinction is made between variable and fixed costs,absorption costing is not well suited for CVP computations.i. The cost of a unit of product consists of directmaterials, direct labor, and both variable and fixedoverhead .ii. Variable and fixed selling and administrative expensesare treated as period costs and are deducted fromrevenue as incurred.Quick Check – absorption vs. variable costingII. Harvey Company —an exampleA. Unit cost computationsi. Assume Harvey Company produces a single product with available information as shown.ii. The unit product costs under absorption and variablecosting would be $16 and $10, respectively.1. Under absorption costing, all production costs ,variable and fixed, are included when determiningunit product cost.2. Under variable costing, only the variableproduction costs are included in product costs.Helpful Hint: Before beginning the forthcoming incomecomparisons, remind students of the relationship between ending inventory and net operating income. Higher ending inventory results in higher net operating income since costs of goods available for sale less ending inventory equals cost of goods sold. Therefore, a higher ending inventory results in a lower expense (cost of goods sold) deducted to arrive at net operating income.Learning Objective 2: Prepare income statements using both variable and absorption costing.B. Income comparison of variable and absorption costingi. Harvey Company —additional assumptions.1.20,000 units were sold during the year. 2.The selling price per unit is$30. 3. There isno beginning inventory. ii. Variable costing1. The unit product cost is $10.2. All $150,000 of fixed manufacturing cost is expensed in the current period.3. The net operating income is $90,000. iii. Absorption costing1. The unit product cost is $16.2. The fixed manufacturing overhead cost deferred in inventory is $30,000 (= 5,000 units × $6 per unit).3. The net operating income is $120,000.Helpful Hint: Explain that under absorption costing, therecognition of fixed costs as an expense is really a timing issue. When the items are sold, the fixed costs will bereflected on the income statement as part of cost of goods sold.Learning objective 3: Reconcile variable costing and absorption costing net operating incomes and explain whythe two amounts differ.iv. Comparing the two methods1. Under absorption costing, $120,000 of fixedmanufacturing overhead is included in cost of goodssold and $30,000 is deferred in ending inventory asan asset on the balance sheet.2. Under variable costing, the entire $150,000 of fixedmanufacturing overhead is treated as a periodexpense.a. The variable costing ending inventory is $30,000less than absorption costing , thus explaining thedifference in net operating income between thetwo methods.3. The difference in net operating income between thetwo methods ($30,000) can also be reconciled bymultiplying the number of units in ending inventory(5,000 units ) by the fixed manufacturing overheadper unit ($6) that is deferred in ending inventoryunder absorption costing.C. Extended comparisons of income datai. Harvey Company —additional assumptions/facts1. 30,000 units were sold in year2. 2. The selling price per unit, variable costs per unit,total fixed costs, and number of units producedremain unchanged .3. 5,000 units are in beginning inventory.ii. Unit cost computations1.Since the variable costs per unit, total fixed costs, and the number of units produced remained unchanged, the unit cost computations also remain unchanged. iii. Variable costing 1. The unit product cost is $10. 2. All $150,000 of fixed manufacturing overhead cost is expensed in the current period. 3. The net operating income is $260,000. iv. Absorption costing 1. The unit product cost is $16. 2. The fixed manufacturing overhead cost released from inventory is $30,000 (= 5,000 units × $6 per unit). 3. The net operating income is $230,000.v. Comparing the two methods 1. The difference in net operating income between the two methods ($30,000) can be reconciled by multiplying the number of units in beginning inventory (5,000 units ) by the fixed manufacturing overhead per unit ($6) that is released from beginning inventory under absorption costing.2. Across the two-year time frame, both methods reported the same total net operating income ($350,000). This is because over an extended period of time sales cannot exceed production, nor canproduction much exceed sales. The shorter the timeperiod, the more the net operating income figureswill tend to differ.D. Summary of key insightsi.Whenunits produced equals units sold, the twomethods report the same net operating income .ii. When units produced are greater than units sold , asin year 1 for Harvey, absorption net operating incomeis greater than variable costing net operating income . iii. When units produced are less than units sold , as inyear 2 for Harvey, absorption costing net operatingincome is less than variable costing net operatingincome .III. Advantages of variable costing and the contribution approachA. Enabling CVP analysisi. Variable costing categorizes costs as fixed and variable so it is much easier to use this income statement format for CVP analysis.ii.Absorption costing assigns per unit fixed manufacturing overhead costs to production. This can potentiallyproduce positive net operating income even whenthe number of units sold is less than the breakevenpoint.B. Explaining changes in net operating incomei.Variable costingnet operating income is only affectedby changes in unit sales. It is not affected by thenumber of units produced. As a general rule, when salesgo up net operating income goes up and vice versa.ii.Absorption costing net operating income is influenced by changes in unit sales and units of production. Netoperating income can be increased simply by producingmore units even if those units are not sold.D.Supporting decision makingi.Variable costing correctly identifies the additionalvariable costs incurred to make one more unit. Italso emphasizes the impact of fixed costs on profits.ii.Absorption costing gives the impression that fixed manufacturing overhead is variable with respect tothe number of units produced, but it is not. This canlead to inappropriate pricing decisions and productdiscontinuation decisions.IV. Segmented income statements and the contribution approach Learning Objective 4: Prepare a segmented incomestatement that differentiates traceable fixed costs fromcommon fixed costs and use it to make decisions.A.Key concepts/definitionsi. A segment is a part or activity of an organizationabout which managers would like cost, revenue, orprofit data.ii.Examples of segments include divisions of acompany, sales territories, individual stores, servicecenters, manufacturing plants, marketingdepartments, individual customers, and product lines.iii.There are two keys to building segmented income statements.1.First, a contribution format should be usedbecause it separates fixed from variable costsand it enables the calculation of a contributionmargin.a.The contribution margin is especially useful indecisions involving temporary uses ofcapacity such as special orders.2.Second, traceable fixed costs should be separatedfrom common fixed costs to enable thecalculation of a segment margin. Furtherclarification of these terms is as follows:a. A traceable fixed cost of a segment is a fixed cost that is incurred because of the existence of the segment. If the segment were eliminated, the fixed cost would disappear. Examples of traceable fixed costs include: (1). The salary of the Fritos product manager at PepsiCo is a traceable fixed cost of the Fritos business segment of PepsiCo. (2). The maintenance cost for the building in which Boeing 747s are assembled is a traceable fixed cost of the 747 business segment of Boeing.b. A common fixed cost is a fixed cost that supports the operations of more than one segment, but is not traceable in whole or in part to any one segment . Examples of common fixed costs include: (1). The salary of the CEO of General Motors is a common fixed cost of the various divisions of General Motors. (2). The cost of heating a Safeway or Kroger grocery store is a common fixed cost of the various departments – groceries, produce, bakery, etc. c. It is important to realize that the traceable fixed costs of one segment may be a common fixed cost of another segment . For example: (1). The landing fee paid to land an airplane atan airport is traceable to a particular flight, but it is not traceable to first-class, business-class, and economy-class passengers.Helpful Hint: In practice, a great deal of disagreement exists about what costs are traceable and what costs are common. Some people claim that except for direct materials, virtually all costs are common fixed costs that cannot be traced to products. Others assert that all costs are traceable toproducts; there are no common costs. The truth probably lies somewhere in the middle – many costs can be traced to products but not all costs.d. A segment margin is computed by subtracting the traceable fixed costs of a segment from itscontribution margin.(1). The segment margin is a valuable tool forassessing the long-run profitability of asegment.(2). Allocating common costs to segmentsreduces the value of the segment marginas a guide to long-run segmentprofitability.Helpful Hint: Explain that a segment should notautomatically be eliminated if its segment margin is negative. If a company that produces hair-styling productsdiscontinues its styling gel, sales on its shampoo and conditioner might fall due to the unavailability of the eliminated product.B. Segmented income statements – an examplei.Assume that Webber, Inc. has two divisions –the Computer Division and the Television Division.1. The contribution format income statement for the Television Division is as shown. Notice:a. Cost of goods sold consists of variable manufacturing costs.b. Fixed and variable costs are listed in separate sections .c. Contribution margin is computed by taking sales minus variable costs.d. The divisional segment margin represents the Television Division’s contribution to overall company profits. 2. The Television Division’s results can be rolled into Webber, Inc.’s overall results as shown. Notice: a. The results of the Television and Computer Divisions sum to the results shown for the whole company. b. The common costs for the company as a whole ($25,000) are not allocated to the divisions . 3. The Television Division’s results can also be broken down into smaller segments. This enables us to see how traceable fixed costs of the Television Division can become common costs of smaller segments . a. Assume that the Television Division can be broken down into two major product lines – Regular and Big Screen . b. Assume that the segment margins for these two product lines are as shown. c. Of the $90,000 of fixed costs that were previously traceable to the Television Division, $80,000 (= $45,000 + $35,000) is traceable to the two product lines and $10,000 is a common cost.C. Segmented income statements —decision making and break-even analysisi.To illustrate how the Television Division’s results can be used fordecision making, assume Webber believes that if the Television Division spends $5,000 additionaldollars on advertising it will increase sales of Regular and Big Screen televisions by 5%. Webber can compute the profit impact of this course of action as follows:1. The Regular product line contribution margin would increase by $5,250.2. The Big Screen product line contribution margin would increase by $2,250.3. The Television Division’s segment margin would increase by $2,500. Learning Objective 5: Compute companywide and segment break-even points for a company with traceable fixed costs. ii. To demonstrate how to calculate companywide and segmented break-even points , let’s refer back to the companywide income statement segmented into the Television and Computer Divisions. 1. The companywide break-even point is computed by dividing the sum of the company’s traceable fixed costs and common fixed costs by the company’s overall contribution margin ratio . a. This equation can be used to compute Webber’s companywide break-even point of $361,111.2. A business segment’s break-even point is computedby dividing its traceable fixed costs by itscontribution margin ratio.a. Using this equation, the break-even point for theTelevision Division is $180,000.b. The break-even point for the Computer Divisionis $133,333.3. Notice that the companywide common fixed costsare excluded from the segment break-evencalculations. This occurs because the common fixed costs are not traceable to segments and they are not influenced by segment-level decisions.Segmented income statements—common mistakesA.Omission of costsi.The costs assigned to a segment should include all thecosts attributable to that segment from the company’sentire value chain as discussed in Chapter 12.1.Since only manufacturing costs are included inproduct costs under absorption costing, thosecompanies that choose to use absorption costing forsegment reporting purposes will omit from theirprofitability analysis all “upstream” and“downstream” costs.a.“Upstream” costs include research anddevelopment and product design costs.b.“Downstream” costs include marketing,distribution, and customer service costs.c. Although these “upstream” and “downstream” costs are nonmanufacturing costs, they are just as essential to determining product profitability asare manufacturing costs. Omitting them fromprofitability analysis will result in theundercosting of products.Helpful Hint: An example of a company with a very high amount of upstream and downstream costs is apharmaceutical company such as Merck. A great deal of its costs are comprised of research and development and marketing.B. Inappropriate methods for assigning traceable costs to segmentsi.Failure to trace costs directly1. Costs that can be traced directly to specific segments of a company should not be allocated to othersegments . Rather, such costs should be chargeddirectly to the responsible segment. For example: a. The rent for a branch office of an insurancecompany should be charged directly against thebranch office rather than included in acompanywide overhead pool and then spreadthroughout the company.ii. Inappropriate allocation base1. Some companies allocate costs to segments using arbitrary bases . Costs should be allocated tosegments for internal decision making purposes only when the allocation base actually drives the cost being allocated. For example:a. Sales are frequently used to allocate selling and administrative expenses to segments. This should only be done if sales drive these expenses.C. Arbitrarily dividing common costs among segments i. Common costs should not be arbitrarily allocated to segments based on the rational e that “someone has to cover the common costs” for two reasons:1. First, this practice may make a profitable business segment appear to be unprofitable. If the segment is eliminated the revenue lost may exceed the real traceable costs that are avoided.2. Second, allocating common fixed costs forcesmanagers to be held accountable for costs that they cannot control.Quick Check – common costsV. Income statements—an external reporting perspectiveA. Companywide income statementsi.Practically speaking,absorption costing is requiredfor external reports in the United States. IFRS alsorequire absorption costing for external reports.ii.Probably because of the cost of maintaining twoseparate costing systems, most companies useabsorption costing for their external and internal reports.iii.W ith all of the advantages of the contribution approach, one may wonder why the absorption approach is used atall. Perhaps the biggest reason is because:1.Advocates of absorption costing argue that it bettermatches costs with revenues. They contend thatfixed manufacturing costs are just as essential tomanufacturing products as are the variable costs.2.Advocates of variable costing view fixedmanufacturing costs as capacity costs. They arguethat fixed manufacturing costs would be incurredeven if no units were produced.B. Segmented financial informationi. U.S. GAAP and IFRS require publicly-tradedcompanies to include segmented financial data intheir annual reports. These rulings have implications forinternal segment reporting because:.1. They mandate that companies must prepare external Array segmented reports using the same methods that theyuse for internal segmented reports. This requirement motivates managers to avoid using the contribution approach for internal reporting purposes because if they did they would be required to:a. Share this sensitive data with the public.b. Reconcile these reports with applicable rules forconsolidated reporting purposes.。

Chapter 5 Lecture NotesChapter theme: Cost-volume-profit (CVP) analysis helps managers understand the interrelationships among cost,volume, and profit by focusing their attention on theinteractions among the prices of products, volume ofactivity, per unit variable costs, total fixed costs, andmix of products sold. It is a vital tool used in manybusiness decisions such as deciding what products andservices to offer, what prices to charge, what marketingstrategy to use, and what cost structure to maintain.I.Assumptions of CVP analysisA.Three key assumptions underlie CVP analysis:i.Selling price is constant.ii.Costs are linear and can be accurately divided into variable and fixed components. The variable costsare constant per unit, and the fixed costs areconstant in total over the entire relevant range.iii.In multiproduct companies, the mix of products sold remains constant.Helpful Hint: Point out that nothing is sacred aboutthese assumptions. When violations of theseassumptions are significant, managers can and domodify the basic CVP model. Spreadsheets allowpractical models that incorporate more realisticassumptions. For example, nonlinear cost functionswith step fixed costs can be modeled using “If…Then”functions.II. The basics of cost-volume-profit (CVP) analysi sLearning Objective 1: Explain how changes in activity affect contribution margin and net operating income.A. The contribution format income statement is helpful to managers in judging the impact on profits of changes in selling price, cost, or volume. For example, let's look at a hypothetical contribution format income statement for Racing Bicycle Company (RBC). Notice:i. The emphasis is on cost behavior . Variable expenses are separate from fixed expenses. ii. The contribution margin is defined as the amount remaining from sales revenue after variableexpenses have been deducted.iii. Contribution margin is used first to cover fixed expenses . Any remaining contribution margincontributes to net operating income .iv. Sales, variable expenses, and contribution margincan also be expressed on a per unit basis . Thus:1. For each additional unit RBC sells, $200 more in contribution margin will help to cover fixedexpenses and provide a profit.2. Notice, each month RBC must generate at least $80,000 in total contribution margin to break-even (which is the level of sales at whichprofit is zero).3. Therefore, if RBC sells 400 units a month, itwill be operating at the break-even point .4.If RBC sells one more bike (401 bikes), netoperating income will increase by $200.v.You do not need to prepare an income statement to estimate profits at a particular sales volume. Simply multiply the number of units sold above break-evenby the contribution margin per unit.1.For example, if RBC sells 430 bikes, its netoperating income will be $6,000.B.CVP relationships in equation form (for those whoprefer an algebraic approach to solving problems in the chapter)i.The contribution format income statement can beexpressed in equation form as shown on this slide.1.This equation can be used to show the profitRBC earns if it sells 401 bikes. Notice, theanswer of $200 mirrors our earlier solution.ii.When a company has only one product we can further refine this equation as shown on this slide.1.This equation can also be used to show the$200 profit RBC earns if it sells 401 bikes.iii.The profit equation can also be expressed in terms of unit contribution margin as shown on this slide.1.This equation can also be used to computeRBC’s $200 profit if it sells 401 bikes.Learning Objective 2: Prepare and interpret a cost-volume-profit (CVP) graph and a profit graph.C. CVP relationships in graphic formi. The relationships among revenue, cost, profit, and volume can be expressed graphically by preparing a cost-volume-profit (CVP) graph. To illustrate, we will use contribution format income statements for RBC at 0, 200, 400, and 600 units sold. Helpful Hint: Mention to students that the graphic form of CVP analysis may be preferable to them if they are uncomfortable with algebraic equations.ii. In a CVP graph, unit volume is represented on the horizontal (X) axis and dollars on the vertical (Y) axis . A CVP graph can be prepared in three steps . 1. Draw a line parallel to the volume axis to represent total fixed expenses. 2. Choose some sales volume (e.g., 400 units ) and plot the point representing total expenses (e.g., fixed and variable) at that sales volume. Draw a line through the data point back to where the fixed expenses line intersects the dollar axis. 3. Choose some sales volume (e.g., 400 units ) and plot the point representing total sales dollars at the chosen activity level. Draw a line through the data point back to the origin.iii. Interpreting the CVP graph .1. The break-even point is where the total revenue and total expense lines intersect.2. The profit or loss at any given sales level is measured by the vertical distance between thetotal revenue and the total expense lines.Helpful Hint: Ask students what the CVP graph would look like for a public agency like a county hospital receiving a fixed budget each year and collecting fees less than its variable costs. It would look like this:This is the reverse of the usual situation. If such an organization has volume above the break-even point, it will experience financial difficulties.iv. An even simpler form of the CVP graph is calledthe profit graph . The profit graph is based on the equation shown on this slide.1. To plot the graph, compute the profit at two different sales volumes, plot the points, andthen connect them with a straight line. This slide contains the profit graph for RBC. Notice: a. The sales volumes plotted on this graph are 300 and 500 bikes.b. The breakeven point is 400 bikes.D. Contribution margin ratio (CM ratio) and the variable expense ratioLearning Objective 3: Use the contribution margin ratio (CM ratio) to compute changes in contribution margin and net operating income resulting from changes in sales volume. i. The CM ratio is calculated by dividing the total contribution margin by total sales.1. For RBC, the CM ratio is 40%. Thus, each $1.00 increase in sales results in a total contribution margin increase of 40¢. ii. The CM ratio can also be calculated by dividing the contribution margin per unit by the selling price per unit .1. For RBC, the CM ratio is 40%.iii. Similarly, variable expenses as a percentage of sales is referred to as the variable expense ratio.1. For RBC, the variable expense ratio is 60%.iv.The contribution margin ratio and the variableexpense ratio can be mathematically related to one another: CM ratio = 1 – Variable expense ratio.v. If RBC increases sales from 400 to 500 bikes, the increase in contribution margin ($20,000) can be calculated by multiplying the increase in sales ($50,000) by the CM ratio (40%).Quick Check – contribution margin ratiovi. The relation between profit and the CM ratio canalso be expressed in terms of the equation shown on this slide. 1. For example, we can use this equation tocalculate RBC’s profit of $20,000 at a volume of 500 bikes .E. Applications of CVP concepts Learning Objective 4: Show the effects on net operating income of changes in variable costs, fixed costs, selling price, and volume.Helpful Hint: The five examples that are forthcoming should indicate to students the range of uses of CVP analysis. In addition to assisting management in determining the level of sales that is needed to break-even or generate a certain dollar amount of profit, the examples illustrate how the results of alternative decisions can be quickly determined.i. Change in fixed cost and sales volume.1. What is the profit impact if RBC can increase unit sales from 500 to 540 by increasing the monthly advertising budget by $10,000? a. Preparing a contribution format income statement reveals a $2,000 decrease in profits. b. A shortcut solution using incremental analysis also reveals a $2,000 decrease in profits.ii. Change in variable costs and salesvolume .1. What is the profit impact if RBC can usehigher quality raw materials, thus increasing variable costs per unit by $10, to generate an increase in unit sales from 500 to 580? a. The contribution format income statement reveals a $10,200 increase in profits.iii. Change in fixed cost, sales price, and sales volume .1. What is the profit impact if RBC: (1) cuts itsselling price $20 per unit, (2) increases its advertising budget by $15,000 per month, and (3) increases unit sales from 500 to 650 units per month? a. The contribution format income statementreveals a $2,000 increase in profits.iv.Change in variable cost, fixed cost, and salesvolume. 1. What is the profit impact if RBC: (1) pays a $15 sales commission per bike sold instead of paying salespersons flat salaries that currently total $6,000 per month, and (2) increases unit sales from 500 to 575 bikes? a. The contribution format income statement reveals a $12,375 increase in profits. v. Change in regular sales price. 1. If RBC has an opportunity to sell 150 bikes to a wholesaler without disturbing sales to other customers or fixed expenses, what price should it quote to the wholesaler if it wants to increase monthly profits by $3,000? a. The price quote should be $320 per bike .III. Break-even analysisLearning Objective 5: Determine the break-even point.A.The equation and formula methods can be used to determine the unit sales and dollar sales needed toachieve a target profit of zero. For example, let’s revisit the information from RBC:i.Suppose RBC wants to know how many bikes must be sold to break-even (i.e. earn a target profit of $0). The equation shown on this slide can be used toanswer this question.1. The equation method reveals that 400 bikes must be sold to breakeven.2. The formula method can also be used to determine that 400 bikes must be sold to breakeven. ii. Suppose RBC wants to compute the sales dollars required to break-even (i.e. earn a target profit of $0). The equation shown here can be used to answer this question. 1. The equation method reveals that sales of $200,000 will enable the company to break-even. 2. The formula method can also be used to determine that sales of $200,000 will enable the company to break-even. Quick Check – break-even calculationsB.Target profit analysisLearning Objective 6: Determine the level of sales needed to achieve a desired target profit.i.Intarget profit analysis, we estimate what salesvolume is needed to achieve a specific target profit.We can compute the number of unitsthat must besold to attain a target profit using either theequation method or theformula method.1.The equation method is summarized on thisslide. Our goal is to solve for the unknown “Q”which represents the quantity of units that must be sold to attain the target profit.2.For example: Suppose RBC wants to knowhow many bikes must be sold to earn a targetprofit of $100,000.a.The equation method can be used todetermine that 900 bikes must be sold toearn the desired target profit.b.The formula method is summarized on thisslide. It can also be used to compute thequantity of units that must be sold to attain atarget profit.3.For example:Suppose RBC wants to knowhow many bikes must be sold to earn a targetprofit of $100,000.a.The formula method can be used todetermine that 900 bikes must be sold toearn the desired target profit.ii. We can also compute the target profit in terms of sales dollars using either the equation method or the formula method .1. The equation method is summarized on this slide . Our goal is to solve for the unknown“Sales,” which represents the dollar amount of sales that must be sold to attain the target profit.2. For example: Suppose RBC wants to compute the sales dollars required to earn a targetprofit of $100,000.a. The equation method can be used todetermine that sales must be $450,000 toearn the desired target profit.b. The formula method is summarized on this slide. It can also be used to compute thedollar sales needed to attain a target profit.Quick Check – target profit calculationsC. The margin of safetyLearning Objective 7: Compute the margin of safety and explain its significance. i. The margin of safety in dollars is the excess of budgeted (or actual) sales over the break-even volume of sales .1. For example: If we assume that RBC has actual sales of $250,000, given that we have already determined the break-even sales to be $200,000, the margin of safety is $50,000.2. The margin of safety can be expressed as a percent of sales. a. For example: RBC’s margin of safety is 20% of sales .3. The margin of safety can be expressed in terms of the number of units sold.a. For example: RBC’s margin of safety is100 bikes .Quick Check – margin of safety calculationsIV.CVP considerations in choosing a cost structur eA. Cost structure and profit stabilityi. Cost structure refers to the relative proportion of fixed and variable costs in an organization. Managers often have some latitude in determining their organization's cost structure.ii. There are advantages and disadvantages to high fixed cost (or low variable cost) and low fixed cost (or high variable cost) structures.1. An advantage of a high fixed cost structure is that income will be higher in good yearscompared to companies with a lowerproportion of fixed costs.2. A disadvantage of a high fixed cost structure is that income will be lower in bad years compared to companies with a lower proportion of fixed costs.3. Companies with low fixed cost structures enjoy greater stability in income across good and bad years.Learning Objective 8: Compute the degree of operating leverage at a particular level of sales and explain how it can be used to predict changes in net operating income.B. Operating leveragei. Operating leverage is a measure of how sensitive net operating income is to percentage changes in sales . i. The degree of operating leverage is a measure, atany given level of sales, of how a percentagechange in sales volume will affect profits. It is computed as shown on this slide.ii. To illustra te, let’s revisit the contribution format income statement for RBC: 1. RBC’s degree of operating leverage is 5 ($100,000/$20,000). 2. With an operating leverage of 5, if RBC increases its sales by 10%, net operatingincome would increase by 50%.a.The 50% increase can be verified bypreparing a contribution approach income statement.Quick Check –operating leverage calculationsHelpful Hint: Emphasize that the degree of operating leverage is not a constant like unit variable cost or unit contribution margin that a manager can apply withconfidence in a variety of situations. The degree ofoperating leverage depends on the level of sales andmust be recomputed each time the sales level changes.Also, note that operating leverage is greatest at saleslevels near the break-even point and it decreases assales and profits rise.V.Structuring sales commission spanies generally compensate salespeople bypaying them either a commission based on sales or asalary plus a sales commission. Commissions based onsales dollars can lead to lower profits in a company.Consider the following illustration:i.Pipeline Unlimited produces two types ofsurfboards, the XR7 and the Turbo. The XR7 sellsfor $100 and generates a contribution margin perunit of $25. The Turbo sells for $150 and earns acontribution margin per unit of $18.ii. Salespeople compensated based on sales commission will push hard to sell the Turbo even-though the XR7 earns a higher contribution margin per unit.iii. To eliminate this type of conflict,commissions canbe based on contribution margin rather than on selling price alone.VI. The concept of sales mi xLearning Objective 9: Compute the break-even point for a multiproduct company and explain the effects ofshifts in the sales mix on contribution margin and the break-even point.A. The term sales mix refers to the relative proportions in which a company’s products are sold. Since different products have different selling prices, variable costs, and contribution margins, when a company sells more than one product, break-even analysis becomes more complex as the following example illustrates:Helpful Hint: Mention that these calculations typically assume a constant sales mix. The rationale for this assumption can be explained as follows. To use simple break-even and target profit formulas, we must assume the firm has a single product. So we do just that – even for multi-product companies. The trick is to assume the company is really selling baskets of products and each basket always contains the various products in the same proportions.i. Assume the RBC sells bikes and carts. The bikes comprise 45% of the company’s total sales revenue and the carts comprise the remaining 55%. The contribution margin ratio for both products combined is 48.2%.ii. The break-even point in sales would be $352,697. The bikes would account for 45% of this amount, or $158,714. The carts would account for 55% of the break-even sales, or $193,983.1. Notice a slight rounding error of $176.。

Chapter 4Lecture NotesChapter theme: Managers need to assign costs to products to facilitate external financial reporting and internal decision making. This chapter illustrates an absorption costing approach to calculating product costs known as process costing .I. Comparison of job-order and process c ostingA. Similarities between job-order and process costingi. Both systems assign material , labor, andoverhead costs to products and they provide a mechanism for computing unit product costs.ii. Both systems use the same manufacturing accounts,including Raw Materials, Work in Process,Manufacturing Overhead, and Finished Goods . iii. The flow of costs through the manufacturingaccounts is basically the same in both systems.B. Differences between job-order and process costingi. Process costing is used when a single product is produced on a continuing basis or for a long periodof time. Job-order costing is used when many different jobs having different productionrequirements are worked on each period.ii. Process costing systems accumulate costs by department and assign them uniformly to all units processed during the period. Job-order costing systems accumulate costs by individual jobs .iii. Process costing systems compute unit costs bydepartment. Job-order costing systems compute unit costs by job on the job cost sheet.Quick Check - process vs. job-order costing II.Cost flows in process costingA. Processing departments - An organizational unit where materials, labor, or overhead costs are added to the product.i. The activity performed in a processing department is performed uniformly on all units passing through it. Furthermore, the output of a processing department must be homogeneous . ii. Products in a process costing environment typically flow in a sequence from one department to another.Learning Objective 1: Record the flow of materials, labor, and overhead through a process costing system.B.The flow of materials, labor, and overhead costsi.The flow of costs through the manufacturing accounts is basically the same for process and job-order costing.1.Direct materials, direct labor, andmanufacturing overhead are added to Work inProcess. When work in process is completed,the costs are transferred to Finished Goods.When finished goods are sold, the costs aretransferred to Cost of Goods Sold.ii.Nonetheless, there is a key fundamental difference between process and job-order costing systems.1.Job-order costing systems trace and applymanufacturing costs to jobs.a.One Work in Process account is often usedto accumulate costs for all jobs. Theindividual job cost sheets serve as asubsidiary ledger.2.Process costing systems trace and applymanufacturing costs to departments.a.A separate Work in Process account ismaintained for each processing department.b.Material, labor, and overhead coststransferred from one department’s Work inProcess account to another department’sWork in Process account are calledtransferred-in costs.iii.T-account and journal entry views of process cost flows (For purposes of this example, assume there are two processing departments—A and B).Helpful Hint: Explain that the journal entries for job-order and process costing are similar, with theexception of the specific Work in Process account for each department under process costing.1.The flow of raw material costs.a.In T-account form:(1).Direct material costs are debited to theappropriate departmental Work inProcess account depending upon wherethe materials were added to theproduction process. The Raw Materialsaccount is credited for thecorresponding amounts.b.In journal entry form:(1).Debit the respective departmental Workin Process accounts. Credit RawMaterials.2.The flow of labor costs.a.In T-account form:(1).Direct labor costs are debited to theappropriate departmental Work inProcess account depending upon wherethe labor was added to the productionprocess. Salaries and Wages Payable iscredited for the corresponding amounts.b. In journal entry form: (1). Debit the respective departmental Work in Process accounts. Credit Salaries and Wages Payable. 3. The flow of manufacturing overhead costs. a. In T-account form: (1). Manufacturing overhead costs are debited to the respective departmental Work in Process accounts. Manufacturing Overhead is credited by the corresponding amounts. (a). Predetermined overhead rates are usually used to apply overhead to the departments. b. In journal entry form: (1). Debit the appropriate departmental Work in Process accounts. Credit Manufacturing Overhead.4. The flow of manufacturing costs for partially completed units transferred fromDepartment A to Department B:a. In T-account form:(1). The cost of direct materials, direct labor,and manufacturing overhead assignedto partially completed units fromDepartment A is debited to DepartmentB and credited to Department A.(3). The transferred-in costs from Department A are added to the manufacturing costs incurred in Department B. b. In journal entry form: (1). Debit Work in Process - Department B and credit Work in Process - Department A. 5. The flow of manufacturing costs from the final processing department to finished goods . a. In T-account form: (1). Debit Finished Goods and credit Work in Process - Department B for the amount of the cost of goods manufactured. b. In journal entry form: (1). Debit Finished Goods and credit Work in Process - Department B. 6. The flow of manufacturing costs from Finished Goods to Cost of Goods Sold. a. In T-account form: (1). Debit Cost of Goods Sold and credit Finished Goods. b. In journal entry form: (1). Debit Cost of Goods Sold and credit Finished Goods.III. Process costing computations: three key conceptsA. Key concept #1: Two methodsi. Equivalent units can be calculated two ways .1. The FIFO method is covered in the appendix;theweighted-average method is includedwithin the main portion of the chapter (and it is covered next).2. Characteristics of the weighted-averagemethod:a. This method makes no distinction between work done in the prior and current periods.It blends together units and costs from theprior and current periods.b. The equivalent units of production for adepartment are the number of unitstransferred to the next department (orfinished goods) plus the equivalent units inthe department’s ending work in processinventory.B. Key concept #2: Conversion costsi. Direct labor costs are often small in comparison to the other product costs in process cost systems.1. Therefore, direct labor and manufacturing overhead are often combined into one classification of product cost called conversion costs . The example combines these costs.C. Key concept #3: Equivalent unitsi. Equivalent units - Defined as the product of the number of partially completed units and the percentage completion of those units. ii. Equivalent units need to be calculated because a department usually has some partially completed units in its beginning and ending inventories. These partially completed units complicate the determination of a department’s output for a given period and the unit cost that should be assigned to that output.Helpful Hint: Explain that equivalent units simply restate the ending work in process inventory as if it were comprised of a smaller number of fully completed units.iii. Equivalent units - the basic idea: 1. Two half completed products are equivalent to one complete product. 2. 10,000 units 70% completed are equivalent to 7,000 complete units. Quick Check - calculating equivalent unitsLearning Objective 2: Compute the equivalent units of production using the weighted-average method.IV. W eighted-average method--ExampleA. Assume that Smith Company’s Assembly Department reported activity for June as shown on this slide. i. Step 1: Compute the equivalent units of production (weighted average method)1. The first component in the calculation of the equivalent units is to identify the units completed and transferred out of the department in June (5,400 units for materials and conversion ).2. The second component is to identify the equivalent units of production in ending work in process with respect to materials for the month (540 units ) and adding this to the 5,400 units from step one.3. The third component is to identify the equivalent units of production in ending work in process with respect to conversion for the month (270 units ) and adding this to the 5,400 units from step one.Helpful Hint: Explain that there will most likely be differences in the equivalent unit calculations between materials and conversion costs, as materials are usually added at the beginning of production, while conversion costs are added during the period.4. The equivalent units of production equals the units completed and transferred out (5,400 units ) plus the equivalent units remaining in work in process (540 units for materials and 270 units for conversion ).5. A different visual depiction of the equivalent units calculation for materials is shown on this slide.6. A different visual depiction of the equivalent units calculation for conversion is shown on this slide. Helpful Hint: The treatment of beginning inventory under the weighted-average method often puzzles students, since work done in the prior periods is included in the equivalent units. Explain that this is called the weighted-average method precisely because it averages together beginning inventory and work performed in the current period. Costs and units are treated consistently. Both the equivalent units and the costs that go into the unit cost calculations under the weighted-average method include amounts already in beginning inventory.Learning Objective 3: Compute the cost per equivalent unit using the weighted-average method. ii. Step 2: Computing the cost per equivalent unit (weighted average method)1. Assume the following additional facts with respect to Smith Company’s Assembly Department.2. The formula for computing the cost per equivalent units is as shown.3. The numerators for Smith Company ($124,740 for materials and $85,050 for conversion ) are computed as shown.4. The cost per equivalent unit for materials ($21.00) and conversion ($15.00) is computed as shown.a. The equivalent units of production (5,940for materials and 5,670 for conversion )were computed on a prior slide.iii. Step 3: Assign costs to units (weightedaverage method)Learning Objective 4: Assign costs to units using the weighted-average method.1. Computing the cost of ending work in processinventory. a. The first component of the calculation is to record the equivalent units of production inending work in process inventory (540 unitsfor materials and 270 units forconversion).b. The second component of the calculation is to record the cost per equivalent unit ($21.00for materials and $15.00 for conversion).compute the cost of ending work in process inventory ($11,340 for materials, $4,050 for conversion, and $15,390 in total).2.Computing the cost of units transferred out .a.The first component of the calculation is to record the units transferred out to the next department (5,400 units for materials and conversion ). b. The second component of the calculation is to record the cost per equivalent unit ($21.00 for materials and $15.00 for conversion ). c. The third component of the calculation is to compute the cost of units transferred out ($113,400 for materials, $81,000 for conversion, and $194,400 in total ). Learning Objective 5: Prepare a cost reconciliation report using the weighted-average method. iv. Step 4: Prepare a cost reconciliation report1. Computing the costs to be accounted for: a. The first component of the calculation is to record the cost of beginning work in process as shown on slide 43 ($10,039).to record the costs added to production during the period as shown on slide 43 ($199,751). c. The third component of the calculation is to sum these two costs ($209,790). 2. Computing the costs accounted for : a. The first component of the calculation is to record the previously computed cost of ending working process inventory ($15,390). b. The second component of the calculation isto record the previously computed cost ofunits transferred out ($194,400).c. The third component of the calculation is to sum these two costs ($209,790).3. Notice the two totals agree indicating that all costs have been accounted for.V.Operation costingA. Operation costing is a hybrid of job-order and process costing because it possesses attributes of both approaches. i. Operation costing is commonly used when batches of many different products pass through the same processing departments.1.For example, similar to job-order costing, a Array shoe manufacturer may charge each batch ofshoes for its own specific material costs (e.g., shoes made with expensive leather would becharged accordingly, as would shoes madewith inexpensive synthetic materials).2.Similar to process costing, the shoemanufacturer may accumulate the labor andoverhead costs by department and assign thesame conversion cost per unit to each shoeregardless of the shoe style.。

Chapter 3Lecture NotesChapter theme: Companies use job-order costing to assign manufacturing costs to individual jobs. This chapter describes how companies use job-order costing to prepare a balance sheet and an income statement for external reporting purposes.Important vocabulary termsA.Job-order costing– A costing system used insituations where many different products, jobs, orservices are produced each period.B.Absorption costing– A costing method that includesall manufacturing costs—direct materials, direct labor,and both variable and fixed manufacturing overhead—in the cost of a product.C.Allocation base– A measure of activity such as directlabor-hours or machine-hours that is used to assigncosts to cost objects.D.Predetermined overhead rate– A rate used to chargemanufacturing overhead cost to jobs that is establishedin advance for each period. It is computed using thefollowing equation:i.Predetermined overhead rate = Estimated totalmanufacturing overhead cost ÷ Estimated totalamount of the allocation base3E. Overhead application – The process of assigning overhead costs to specific jobs using the following formula:i. Overhead applied to a particular job =Predetermined overhead rate x Amount ofallocation base incurred by the jobF. Normal costing – A costing system in which overhead costs are applied to a job by multiplying apredetermined overhead rate by the actual amount of the allocation base incurred by the job.G. Job cost sheet – A form that records the direct materials, direct labor, and manufacturing overhead cost charged to a job.II.Job-order costing the flow of costsLearning Objectives 1 and 2: Understand the flow of costs in a job-order costing system and prepare appropriate journal entries to record costs. Use T-accounts to show the flow of costs in a job-order costing system.Helpful Hint: Sometimes students need a brief review of journal entries and the use of T-accounts beforebeginning this section of the chapter.A.Key definitionsi.Raw materials– Include any materials that go into the final product.ii.Work in process– Consists of units of production that are only partially complete and will requirefurther work before they are ready for sale tocustomers.iii.Finished goods– Consist of completed units of product that have not yet been sold to customers.iv.Cost of goods manufactured– Includes the manufacturing costs associated with the goods thatwere finished during the period.B.Flow of cost: a conceptual overviewi.Raw materials purchases are recorded in the RawMaterials inventory account.ii.When raw materials are used in production as direct materials, their costs are transferred to theWork in Process inventory account.iii.To transform direct materials into completed jobs, direct labor cost is added to the Work in Processinventory account.iv.Manufacturing overhead cost is applied to Work in Process by multiplying the predeterminedoverhead rate by the actual quantity of theallocation base consumed by each job.v. When jobs are completed , their costs aretransferred from the Work in Process inventoryaccount to the Finished Goods inventory account.vi. The amount transferred from the Work in Processinventory account to the Finished Goods inventory account is referred to as the cost of goodsmanufactured .vii. As goods are sold , their costs are transferred fromthe Finished Goods inventory account to Cost of Goods Sold.viii. Period costs (or selling and administrativeexpenses) do not flow through inventories on the balance sheet. They are recorded as expenses on the income statement in the period incurred.C. Transactions (in T-account and journal entry form) that capture the flow of costs in a job-order costing system are as follows:i. The purchase and issue of materials1. In T-account form :a. The cost of raw material purchases isdebited, and although not shown, the creditside of the transaction would be to AccountsPayable.b. The cost of direct material requisitioned isdebited to Work in Process and added to thejob cost sheets which serve as a subsidiaryledger.c. The cost of indirect material requisitions isdebited to Manufacturing Overhead.a. Debit Raw Materials and credit Accounts Payable.b. Debit Work in Process and Manufacturing Overhead and credit Raw Materials.ii.The recording of labor cost1.In T-account form : a.Direct labor costs are debited to Work in Process and added to the job cost sheetswhich serve as a subsidiary ledger. b. Indirect labor costs are debited to Manufacturing Overhead. 2. In journal entry form : a. Debit Work in Process and Manufacturing Overhead and credit Salaries and Wages Payable. iii.Recording actual manufacturing overhead costs (other than indirect materials and indirect labor) 1. In T-account form : a. As they are incurred, the actual manufacturing overhead costs are debited to Manufacturing Overhead.b. The credit side of the entry is to Cash orvarious liability accounts (e.g., AccountsPayable and Property Taxes Payable),prepaid asset accounts (e.g., PrepaidInsurance), and contra-asset accounts(e.g., Accumulated Depreciation).a. Debit Manufacturing Overhead and credit various accounts as shown.iv. Applying manufacturing overhead costs to workin process1. In T-account form : a. Work in process is debited and Manufacturing Overhead is credited by the amount of the actual quantity of the allocation base multiplied by the predetermined rate . b. Actual manufacturing overhead costs are not debited to Work in Process, nor are they charged to jobs via the job cost sheets. c. The Manufacturing Overhead account is a clearing account . The actual amount of overhead incurred during the period on the debit side of the account will almost certainly not equal the amount applied to Work in Process as shown on the credit side of the account. This requires a year-end adjusting entry that will be discussed shortly.2. In journal entry form : a. Debit Work in Process and creditManufacturing Overhead.Helpful Hint: Students sometimes have difficulty understanding the use of Manufacturing Overhead as a clearing account. Explain that the purpose of the clearing account is to find any discrepancy that exists between the amount of overhead applied to inventory and the amount of overhead actually incurred. Actual overhead incurred is debited to the account. Overhead applied to inventory using the predetermined rate is credited to the account.v.Accounting for nonmanufacturing costsHelpful Hint: Review the concepts of product and period costs at this point. Since period costs are not directly related to the actual manufacture of the products, they are expensed as incurred.panies that use job-order cost systems toassign manufacturing costs to products alsoincur nonmanufacturing costs.2.Nonmanufacturing costs should not go intothe Manufacturing Overhead account.3.Nonmanufacturing costs are not assigned toindividual jobs, rather they are expensed inthe period incurred. For example:a.The salary expenses of employees thatwork in a marketing, selling, oradministrative capacity are expensed inthe period incurred.b.Advertising expenses are expensed in theperiod incurred.vi. Transferring completed jobs from work inprocess to finished goods1. In T-account form : a. The sum of all amounts transferred from work in process to finished goods represents the cost of goods manufactured for the period. b. The Finished Goods Inventory is debited and the Work in Process account is credited.2. In journal entry form : a. Debit Finished Goods and credit Work in Process.vii.Transferring finished goods to cost of goods s old 1. In T-account form : a. Debit Cost of Goods Sold and credit Finished Goods. b. If only a portion of the units associated with a particular job are shipped, then the unit cost figure from the job cost sheet is used to determine the amount of the journal entry. c. This journal entry is also accompanied by a journal entry that recognizes the sales revenue. 2. In journal entry form : a. Debit Accounts Receivable and credit Sales.b. Debit Cost of Goods Sold and creditFinished Goods.Helpful Hint: As a concluding thought, remind studentsthat all inventory accounts are governed by the samelogic: Beginning inventory + Additions = EndingInventory + Transfers out. In the case of raw materials,transfers out consist of both direct and indirectmaterials requisitions. Direct materials requisitions areadded to Work in Process inventory. Indirect materialsrequisitions are debited to Manufacturing Overhead.Additions to Work in Process consist of direct materialsrequisitions, direct labor, and overhead applied.Transfers out of Work in Process consist of coststransferred to Finished Goods. Transfers out ofFinished Goods consist of Cost of Goods Sold.III.Schedules of cost of goods manufactured and cost of goods soldLearning Objective 3: Prepare schedules of cost ofgoods manufactured and cost of goods sold and anincome statement.A.Key conceptsi.This schedule contains three types of costs,namely direct materials, direct labor, andmanufacturing overhead.ii.It calculates the cost of raw material and direct labor used in production and the amount ofmanufacturing overhead applied to production.iii.I t calculates the manufacturing costs associated with goods that were finished during the period.B. Product cost flowsiv. T o create a schedule of cost of goods manufactured, as well as a balance sheet and income statement, it is important to understand the flow of product costs: 1. Raw material purchases made during the period are added to beginning raw materials inventory. The ending raw materials inventory is deducted to arrive at the raw materials used in production . a. As items are removed from raw materials inventory and placed into the production process, they are called direct materials . 2. Direct labor used in production and manufacturing overhead applied to production are added to direct materials to arrive at total manufacturing costs . 3. Total manufacturing costs are added to the beginning work in process to arrive at total work in process . 4. The ending work in process inventory is deducted from the total work in process for the period to arrive at the cost of goods manufactured . 5. The cost of goods manufactured is added to the beginning finished goods inventory to arrive at cost of goods available for sale. The ending finished goods inventory is deducted from this figure to arrive at cost of goods sold . Quick Check product cost flowsIV. Underapplied and overapplied overhead —a closer lookLearning Objective 4: Compute underapplied or overapplied overhead cost and prepare the journal entry to close the balance in Manufacturing Overhead to the appropriate accounts.A. There are two key concepts related to this topic, the first of which is:i. Defining and computing underapplied overheadand overapplied overhead1. The difference between the overhead costapplied to Work in Process and the actualoverhead costs of a period is termed eitherunderapplied overhead or overapplied overhead.a. Underapplied overhead exists when theamount of overhead applied to jobs duringthe period using the predetermined overheadrate is less than the total amount ofoverhead actually incurred during the period.b. Overapplied overhead exists when theamount of overhead applied to jobs duringthe period using the predetermined overheadrate is greater than the total amount ofoverhead actually incurred during the period.Helpful Hint: Students need to understand thatmanufacturing overhead must be estimated at the beginning of the production period. Therefore, theremost likely will be a difference between actual andapplied overhead. A debit balance in the Manufacturing Overhead account indicates more overhead has beenincurred than has been applied to inventory andoverhead is underapplied. A credit balance indicates more overhead has been applied than has beenincurred and overhead is overapplied.puting underapplied or overapplied Array overhead, an example:a.Assume that PearCo’s actual overheadand direct labor hours for the year were$650,000 and 170,000, respectively.b.Recall that PearCo’s total estimatedoverhead and direct labor hours for theyear were $640,000 and 160,000,respectively. Therefore, thepredetermined overhead rate would be $4per direct labor hour.c.The amount of overhead applied to jobsduring the year would be 170,000 directlabor hours × $4 per hour = $680,000.d.In this example, overhead wasoverapplied by $680,000 - $650,000 =$30,000.Quick Check - underapplied overhead and overappliedoverheadii. Disposition of underapplied or overapplied overhead balances1.Any remaining balance in the Manufacturing Overhead account, such as PearCo’s $30,000 of overapplied overhead, is disposed of in one of two ways : a. It can be closed out to Cost of Goods Sold . b. It can be allocated between Work in Process, Finished Goods, and Cost of Goods Sold in proportion to the overhead applied during the current period in the ending balances of these accounts. 2. The journal entry, in T-account form, to close out PearCo’s $30,000 of overapplied overhead into Cost of Goods Sold would be as follows: a. Debit Manufacturing Overhead and credit Cost of Goods Sold. 3. Calculating the allocation of underapplied or overapplied overhead between Work in Process, Finished Goods, and Cost of Goods Sold . a. Assume the overhead applied in Ending Work in Process Inventory, Ending Finished Goods Inventory, and Cost of Goods Sold is $68,000, $204,000, and $408,000, respectively (total value of accounts $680,000). b. In this case, the allocation percentages for Work in Process, Finished Goods, andCost of Goodsc. Sold would be 10%, 30%, and 60%, respectively.d. The allocation of the $30,000 of overapplied overhead would be: Work in Process, $3,000; Finished Goods, $9,000; and Cost of Goods Sold, $18,000. 4. The journal entry to close out the $30,000 of overapplied overhead to each of the three accounts would be: a. Debit Manufacturing Overhead and credit Work in Process, Finished Goods, and Cost of Goods Sold. 5. In summary, there are two methods for disposing of underapplied and overapplied overhead. a. Close out to Cost of Goods Sold. b. Allocate between Work in Process, Finished Goods, and Cost of Goods Sold. c. The latter method is considered more accurate, but it is more complex to compute.Quick Check under- and overapplied overhead。
