Therefore, the cost object is the entire company.  Chabu produces and sells aluminum beverage cans, such as those used for soft drinks.  You may find the following facts about Chabu’s operation useful in responding to this problem:
• Production machines must be cleaned monthly, regardless of the amount of use.
• The more cans produced, the more lubrication is needed.
• Chabu’s monthly production and sales volume is usually at least 1,000 cans, but can be as much as 5,000 cans depending on demand.
• Material handling costs include depreciation on equipment and fuel for loaders.
• Cans are packaged into 100-unit groups prior to sale.
• Research and development costs vary between \$10,000 and \$10,500 per month
• The factory maintenance costs vary between \$6,000 and \$6,500 monthly.
• Chabu’s staff level is constant at 25 people, who are all paid salaries.
• Raw materials are purchased based on expected production levels.
• Sales commissions (based on a per-case amount) are included in marketing department costs.

Exercises

1. Two-point method:

1. Total cost = \$20,000 + \$7,000/\$28,000 x total revenue

= \$20,000 + 0.25 x total revenue

Assumptions:  Sales mix, price, and variable cost remain constant, fixed costs remain fixed, and operations are in the relevant range.  (Note:  The assumption of constant sales mix is not introduced until chapter 3 of the textbook.)

1. a. Total cost for 10,000 units = \$880,000

Total cost for 15,000 units = \$1,260,000

VC = (\$1,260,000 – \$880,000)/(15,000 – 10,000) = \$76

Fixed cost for 15,000 units = \$1,260,000 – \$1,140,000 = \$120,000

Total cost = \$120,000 + \$76Q.

1. Total cost for 18,000 units = \$1,488,000

Average cost = \$82.67

1. a. For production levels between 0 and 5,000 units, TC = \$25,000 + \$10Q

For production levels above 5,000 units, TC = \$25,000 + (\$10 x 5,000) + \$7.50(Q-5,000)

TC = \$37,500 + \$7.50Q

1. Often raw materials are discounted with volume purchases.
2. Below are the three assumptions of this cost function, with examples of reasons why each assumption might not hold. Students may think of other examples.

Fixed costs remain fixed.  Utilities and other types of fixed cost vary each month, but often not based on volume of production.  There can also be unanticipated price changes or changes in discretionary spending.

Variable costs remain constant per unit.  Volume discounts are often given, reducing variable costs after a certain level of purchases.  There can also be unanticipated price changes.

Operations are in the relevant range.  At the extremes of the range, that is very high or very low production levels, costs might be a little different than within those areas of the range where the organization has most experience. In addition, the relevant may be misspecified; operation volumes may increase or decrease to a level of activity in a different relevant range; or managers may make changes to operations or the cost structure.

1. High-low method (Student answers may vary depending on rounding choices.)

1. Cost classification
 Fixed Variable Mixed Oil to lubricate the machines X Salary of the plant manager X Annual subscription to a trade journal X Vacation pay for salaried production employees X Packaging materials X Research and development X Raw materials X Material handling costs X Marketing department costs X Factory maintenance X

1. Cost estimation methods
2. Scatter plots

Description of cost behavior:

Cost of raw materials purchased is variable; total cost at zero volume appears to be zero, and the total cost appears to increase at a constant rate.  The cost of raw materials most likely varies proportionately with the volume of production.

Cost of factory supplies is most likely mixed.  Although the cost behavior is not visually obvious in the above scatter plot, the data for the cost indicate that the cost is higher at higher levels of production.  Also, the cost appears to have a fixed component.  Factory supplies often include a combination of fixed costs, such as janitorial supplies and light bulbs, and variable costs, such as lubrication for machinery.

Production manager salary is a fixed cost; it is constant across all levels of production.  Production manager salaries usually do not vary with volume of production.

1. Two-point method analysis for factory supplies

1. High-low method analysis for factory supplies

1. Scatter plots
2. Graphs

Cost A varies in total amount, but the variation does not appear to be related to variation in volume of the cost driver.  In addition, total cost is fairly high when volume of the cost driver is zero.  It is most likely a fixed cost.

Cost B appears to vary proportionately with volume of the cost driver, and total cost is zero when volume of the cost driver is zero.  It is most likely a variable cost.

Cost C appears to be higher for higher volumes of the cost driver, but total cost is not zero when volume of the cost driver is zero.  It is most likely a mixed cost.

1. Here are possible examples of each cost; students may think of other examples.

Cost A could be utilities, which are a fixed cost but vary due to factors such as weather that are unrelated to a cost driver.

Cost B could be direct labor or direct materials costs, which are driven by production volume.

Cost C could be factory maintenance costs, which are not zero when activity is zero, but increases with volume production or with machine hours.

2. 10 * 6-0.152 = 7.6 hours per page
3. 10 * 10-0.152 = 7.0 hours per page

1. a. Engineered cost estimates

Fruit toppings                     1.50

Chocolate sauce                0.75

Miscellaneous                    0.05

Total cost                 \$3.50

1. Here are several factors that could cause these estimated costs to be inaccurate; students will think of other factors. Employees could eat product, increasing costs.  Any of the ingredient prices could change.  Employees may not use the estimated portions, but include more or less of each ingredient.  Consumer preferences could change so that no fruit toppings are used, or more chocolate sauce is requested.

1. Regression analysis
2. Number of purchase orders is the better independent variable, based on the higher Adjusted R-square statistic.
3. Total purchasing costs = \$497.25 + \$18.72 x number of purchase orders
4. \$497.25 + \$18.72 (340) = \$6,862.05
5. Here are several uncertainties that could affect accuracy of the cost function; students will think of other uncertainties. Normal variations could occur in the amount of resources devoted to purchases orders issued.  An unanticipated salary increase could take place for purchasing employees.  A new employee could be hired who cannot keep up with the work, so a temporary worker is brought in until the new worker is trained.

2. Costs can be determined in a variety of ways, depending upon the purpose of the calculation. In addition, because biases, uncertainties, and management judgments come into play in cost determination, there is no single “correct” way to calculate the cost of a compact disc.
3. The cost of a compact disc might change or vary because of:

Changes in raw material costs from bulk purchases, quality changes, or other factors

Degree of automation vs. labor employed in the production process

Changes in plant layout which reduce overhead costs

Changes in wage rates due to union negotiations and/or outsourcing jobs

Changes in type or cost of packaging materials

Changes in artists’ royalties

1. Learning curves
2. A learning curve explains how costs and/or time can change as workers gain experience in performing a specific task, such as using computer software or building a bridge.
3. The learning curve rate might change or vary for several reasons, including: an incorrect initial estimate, a process being easier / more difficult to master than expected, workers “catching on” more quickly / more slowly than expected.  External factors, such as documentation or conflicting priorities, may also impact a learning curve rate.  Students may think of other reasons.

1. Regression is useful for estimating a cost function when fixed and variable costs are unknown. In this problem, the accountant already knows the cost function (TC = \$100 + \$0.02*Number of copies), so there is no need to estimate the cost function using regression or any other estimation technique.

1. a. TC = \$40,000 + \$20,000/\$80,000 x total revenues = \$40,000 + .25 x total revenues
2. Fixed costs remain fixed, variable costs remain constant, operations are in the relevant range and sales mix remains constant. (Note:  The assumption of constant sales mix is not introduced until chapter 2 of the textbook.)
3. A cost function might provide poor estimates of future costs for the following reasons; students may think of others. The behavior of costs could change after a cost function is developed.  For example, the cost of direct and indirect materials could change, labor rates could change, or operations could move out of the relevant range.  The cost function may be misspecified because inappropriate estimation techniques were used.  For example, a stepwise linear cost function might have been inappropriately estimated using regression analysis, or the high-low method might have been applied to usually high or low (i.e., outlier) data points.

1. TC = F + V*Q. TC is total cost, that is, the total amount of cost that is being explained.  F is fixed costs, which do not change with small changes in volumes of the cost driver. V is variable cost per unit of the cost driver, and that cost remains constant within the relevant range, but its total cost increases proportionately with increases in cost driver volumes.  Q is the quantity of cost driver.

1. Assumptions:

Fixed costs remain constant in total

Variable costs remain constant per unit of the cost driver

Operations in the relevant range

1. Students are asked to list only one assumption and to describe a circumstance in which that assumption will not hold. Below are examples of circumstances for all 3 assumptions; students will think of other circumstances.

Fixed costs remain constant in total:  Variable costs often decrease with volume because of discounts.

Variable costs remain constant per unit of the cost driver:  Fixed costs change because they include utilities and so vary with weather or other factors that are unrelated to production volumes.

Operations in the relevant range:  Business volumes might become unusually high or low due to changes in economic conditions, moving operations into a new relevant range.

1. Regression analysis is a mathematical technique that incorporates all of the observations of cost and cost driver. The high-low and two-point methods use only two data points for cost with their corresponding data points for volume.  Because regression incorporates many more data points, the trend line developed is likely to be a more accurate representation of cost.  In addition, regression output allows one to evaluate the goodness of fit for different cost drivers, and that information is lacking with the other two methods.  The high-low method is a special case of the two-point method and uses only the highest and lowest points, which may not be representative of ordinary operations, so it is the least accurate of the three methods.

1. Below are examples of answers for this question; students will think of other pros and cons. Also see Exhibit 2.17.

Analysis at the account level is an examination of the accounting records to determine whether costs are fixed or variable.  An advantage is that information is in the accounting system and can be accessed without further effort.  A disadvantage is that is does not reflect anticipated changes in cost that would improve the cost function.

Engineering estimates of cost analyze the underlying activities and materials used to produce a good or service to develop the cost function.  Engineering estimates can be very accurate because they consider current period resource use.  However, it is time consuming and may overlook some fixed costs that need to be included in the cost function.

Regression analysis uses past cost data and a statistical method to develop a cost function.  It is often used in conjunction with the analysis at the account level to specify mixed costs.  Regression analysis provides the highest quality information, but it is more  complex and requires knowledge of the spreadsheet program to perform.  Students may have used the two-point method or high-low method as well.

1. When average cost decreases, the cost function includes at least some fixed costs. As the fixed costs are spread over more units, the average cost per unit decreases.  The cost function may or may not include variable costs.

1. A scatter plot is used to increase understanding of cost behavior. For some data, scatter plots provide enough information so that the cost can be categorized.  This would occur when the scatter plot shows that the cost is fixed, that is, either there is very little slope, or there is no apparent trend.  However, if the scatter plot shows a trend line, then further analysis is needed to develop the cost function.  This analysis could include regression or a two-point method.

1. Economic plausibility means that there is an economic explanation for the relationship. For example, the cost of gasoline increases as more miles are driven.  It is economically plausible, then, that miles driven would be an appropriate cost driver for transportation costs.  Alternatively, number of employees is unlikely to be economically related to transportation costs because we do not know if all of the employees drive the cars, or what the relationship is between employees and transportation.  Number of employees is much less likely than miles driven to have an economically plausible relationship with cost of gasoline.

1. Using past cost information cannot completely eliminate the risk of errors in predicting future costs. Managers may be inexperienced or otherwise biased in their use and interpretation of past cost information.  They may employ less-than-suitable cost estimation methods.  Further, economic / human / production factors could change significantly, making past costs unrepresentative of future costs.  Students may think of other factors.

1. Minh cannot know for certain whether the costs of direct materials and labor have changed since the cost estimates were developed. In addition, overhead costs may have changed.  It is possible, although unlikely, that the method of estimating costs could have changed.  In addition, the volume of production affects the average cost, and if this cost is an average, it is based on an estimate of production for the period, and the exact amount of production will not be known until the end of the period.  Students may think of other reasons.

1. Cost estimation methods (students are required to identify only 3)

Analysis at the account level requires examination of accounting records and categorization of costs into fixed, variable, and mixed.  Past costs are then used to predict future costs; however, the costs can easily be updated with expected input price changes.

The two point method requires a scatter plot of data, or at least two years’ observations.  From the data, two points that are representative of normal operations are chosen, the slope (variable cost) is calculated, and then fixed cost is found.

The high-low method is a specific type of the two-point method in which the highest and lowest data points are chosen for the slope and intercept calculations.

Engineered estimates require an analysis of the underlying use of resources (direct materials and direct labor) to predict future costs.

Regression analysis is usually used with the analysis at the account level method, specifically for those costs that are not definitely identified as fixed or variable.  This method uses many data points to fit a trend line with a mathematical calculation that minimizes the squared error of each observation.

Problems

1. a. TC = \$7,128 + \$241 × number of academic programs.

TC = \$3.78 x number of students.  (T-statistic on the coefficient reflecting fixed costs (intercept) is not statistically significant, so we assume fixed cost is zero.)

1. The R-square statistic is the highest for number of academic programs, so the cost function using its data would be the most accurate.
2. Costs normally vary due to unpredictable changes in costs. For example, overhead costs probably include the costs of heating and cooling, which change with weather and utility rates, rather than with programs or students.  In addition, historical cost information about university overhead may not be appropriate for predicting future costs.  There is a high proportion of fixed costs that probably change over time, such as professors’ salaries, staff, and clerical salaries.  In addition, universities sometimes have budget cut-backs, and professor and staff levels may be reduced.  The regression analysis does not take these into consideration.  Students will have thought of others.

1. a. TC = \$2,222 (Coefficient reflecting variable cost (slope) is statistically insignificant, so we set it at zero.)
2. This cost driver, volume of units sold, does not explain very much of the variation in marketing department cost. The R-square is low at 0.40, suggesting that sales volumes only explains about 40% of the variation in cost.  This cost function does a poor job of explaining past costs, and it is likely to perform even less well in estimating future costs.
3. If there are sales commissions as part of the cost, then sales volumes would be a good cost driver for that portion of marketing costs. However, the problem does not specify whether this is a discretionary cost.  Often marketing costs are discretionary costs.
4. If the marketing department buys a lot of advertising, the number of ads or the number of times ads are run could be used as a cost driver. If the marketing department has a lot of employees and they are salaried, the number of employees could drive costs.  Students will think of other potential cost drivers.
5. Discretionary costs are decisions about the amount of cost to incur, and these are often made on an annual basis.
6. Yes, marketing costs could be discretionary. These costs are usually set according to a budget, but can be cut back or increased in the middle of an accounting period.  When profits are higher, it is likely that more is spent on marketing.
7. Because discretionary costs are set by decision, accountants consult the decision makers and ask for an estimate of the cost for the next period.

1. a. Nurses’ salaries and administration are two fixed costs.  We use the most current month’s value to predict next month’s fixed cost. Therefore fixed costs are \$170,000 (\$120,000 + \$50,000).  Vaccine and syringes must be a variable cost because \$60,000/12,000 = \$5, and \$80,000/16,000 = \$5.  It is logical to assume that vaccines and syringes would vary with the number of visits because many patients probably get vaccinations.  Miscellaneous supplies are probably mixed because although the cost increases, it does not increase proportionately with volumes.  Supplies probably include things like lab coats and computer related supplies that do not vary with patient volumes.
2. VC = \$22,000 – \$19,000/16,000 – 12,000 = \$3,000/4,000 = 0.75

Fixed costs:  \$22,000 = F + 0.75 x 16,000 è F = \$10,000

1. TC = (\$120,000 + \$50,000 + \$10,000) + \$5.75 x Q
2. Total cost for 18,000 patients = \$180,000 + \$5.75 x 18,000 = \$283,500
3. Managers cannot know for certain the number of patients that will visit the clinic because they cannot know when a contagious illness will cause more children to become vaccinated. In addition, the birth rate could change.  Costs change over time, and sometimes they change unexpectedly.  For example, nurses’ salaries increase more rapidly when there is a shortage of nurses.  Students will think of factors that could affect patient volumes.

1. a. To develop a cost function, I first consider whether past costs would be relevant in predicting future costs.  If there have been no major changes in the production line or technology, past costs are a good place to start.  Next I pick those costs that are relevant to maintenance from the accounting records.  This is not a discretionary cost, we incur it as part of operations, so I can use past information to develop a cost function to predict future costs, but I need to determine whether any changes in costs are expected.  Then I can use these records and one of the techniques for estimating past costs, such as analysis at the account level.  This could be a mixed cost, so I would also plot the cost against the three potential cost drivers.  If a linear trend is apparent with one or more of these cost drivers, I would use regression analysis to determine whether one cost driver appears to be more accurate than the others.  First I examine R-square and determine the cost driver that best explains the variation in cost.  If none of the drivers have R-squares above about 70%, I may need to identify alternative drivers or consider whether the cost might be primarily fixed.  If one cost driver has an R-square about or above 70%, I would analyze the t-statistics and p-values to determine the cost function.
2. Many different factors can cause costs to be different than estimated. Below are some factors; students will think of others.  It is impossible to perfectly predict future costs because the costs might change, production levels might vary, or other factors could alter the fixed or variable costs.  For example, unanticipated volume discounts might be received.  Operations could be more or less efficient than estimated because workers provide more or less effort.  In addition, the cost function might be poorly estimated.

1. a. Cost function for machine hours:

Variable cost = (\$278,400 – \$240,000)/(4,680 – 3,720) = \$40

Fixed cost = \$91,200

TC = \$91,200 + \$40 * machine hours

1. 1) The high-low method generally reduces the quality of a cost function estimate because it uses only the highest and lowest values of the cost driver.  These values may be atypical, resulting in a distorted cost function.

2)    The cost and production data for this problem are from the first 6 months of operations with a new production system.  When companies install new production systems, it often takes some time before costs and production activities stabilize.  Therefore, the data in this problem might have low quality for estimating future costs.  The quality of data depends on the nature of the production system, how quickly employees learn to use it, and whether engineers continue to make changes in the system as greater production experience is gained.

1. a. TC = \$70,324 + \$14.83*number of setups + \$2.07*machine hours.
2. The R-square provides information about how well the variation in the cost drivers explains variations in cost. In this problem, the R-square is relatively high, so changes in the two drivers explain about 87% of the changes in cost.
3. Both cost drivers are economically plausible. Some labor and supplies are needed when each new setup occurs, so maintenance costs would increase with number of setups.  As machine hours increase, more repairs and oil and routine maintenance is needed, so these seem like they could cause variations in cost.

1. a. Revenue = \$6,911 + \$1,158 x number of clients
2. Here are some uncertainties associated with using the number of clients to predict sales; students will think of others. The average amount of revenue per client may change over time due to economic factors, competition, and customer preferences.  The regression explains only 85% of the variation is past revenue, so it cannot be expected to predict future revenue perfectly.

1. a. Here are several factors related to the cost of fuel; students may think of others.

Type of vehicle

Distance and / or speed driven

Preventive maintenance schedules

Price of fuel

Driving conditions

1. Here are several possible cost drivers; students may think of others.

Number of miles driven

Geographic location of fuel purchase:  domestic, international

1. The purpose of this question is to determine whether students understand that deviations from cost estimates can arise from factors other than use of an inappropriate estimation method. When predicting costs for the future, it is unlikely that actual costs are the same as the prediction.  Changes in the costs and volumes of production affect the cost function.  In addition, there may be changes in vehicle technology that affect efficiency, and costs could decrease.  Student responses will vary.

1. a. Ingredients are variable because we use them as we sell product.

Miscellaneous supplies are also variable

Rent is fixed

Wages for part time employees are variable

Store attendant salary is fixed.

1. TC = (\$1,000 + \$5,000) + (\$7,800 + \$1,200 + \$3,000)/\$20,000 x total revenues

=  \$6,000 + 0.60 x total revenues

1. There are many possible reasons why the cost function might provide an inaccurate estimate. Here are several possible reasons; students may think of others:
• Cost behavior may have been misclassified when creating the cost function
• Revenue might be an inappropriate cost driver for one or more of the variable costs
• Fixed costs might change from the prior month. For example, the cart attendant’s salary might be increased or a new rental agreement might be negotiated.
• Variable costs per dollar of revenue might change from the prior month. For example, the company might negotiate a lower cost for supplies such as napkins, or ingredient costs might fluctuate with food commodity prices.
• The cost function was estimated using only one month’s data, which might not be representative of the activities and costs for other months.

Use the following information for the next 3 questions.

Horton and Associates produces two products named BigBlast and LittleBlast.  Last month 4,000 units of BigBlast and 1,000 units of the LittleBlast were produced and sold.  Following are average prices and costs for last month:

BigBlast                LittleBlast

Selling price                                       \$100                      \$200

Direct materials                                     (25)                       (75)

Direct labor                                           (15)                       (35)

Product line fixed costs                         (10)                       (40)

Corporate fixed costs                            (25)                       (25)

Average margin per unit              \$  20                     \$(    5)

The production lines for both products are highly automated, so large changes in production cause very little change in total direct labor costs.  Workers who are classified as direct labor monitor the production line and are permanent employees who regularly work 40 hours per week.  All costs other than “corporate fixed costs” listed under each product line could be avoided if the product line were dropped.

Direct materials                                     40                          95

Direct labor                                             7                          25

Product line fixed costs                         15                          45

Average margin per unit                \$10                      \$  25

The production lines for both products are highly automated, so large changes in production entail very little change in total direct labor costs.  Workers who are classified as direct labor monitor the production line and are permanent employees who regularly work 40 hours per week.

All product-line costs, other than “corporate fixed costs,” could be avoided if the product line were dropped.  Headquarters fixed costs totaled \$120,000 and the total sales amounted to 6,000 units, so the average corporate fixed cost per unit was \$20.  About \$18,000 of the corporate fixed costs could be avoided if Fun Boots were dropped, and about \$12,000 of the corporate fixed costs could be avoided if Fancy Boots were dropped.  The remaining \$90,000 could be avoided only by going out of business entirely.

1. What is the overall corporate breakeven in total sales revenue, assuming the sales mix is the same as last month’s?
2. What is the breakeven sales volume (in units produced and sold) for Fun Boots? (In other words, what is the sales volume at which Cowboy should be financially indifferent between dropping and retaining Fun Boots?)

1. Yogurt Supreme sells yogurt cones in a variety of natural flavors. Data for a recent month appear below:

Revenue (10,000 cones @ \$0.93 each)                              \$9,300

Cost of ingredients                                     \$3,500

Rent                                                              2,500

Store attendant                                              1,800               7,800

Income                                                                         \$1,500

1. The manager has received a call from a club requesting a bid on 100 cones to be picked up in 3 days. The cones could be made up well in advance by the store attendant during slack periods.  Each cone would require, however, a special plastic cover that costs \$0.05.  What is the minimum acceptable price per cone for this special order?
2. If the club is able to pay no more than the minimum price, what other considerations may affect the decision? List two.

1. Quick Clean sends workers to homes and offices to perform cleaning services for special occasions. There are 4 different outlets and one headquarters for the company.  Headquarters’ costs are allocated to outlets using a rate of 30% of revenue.  The income statement for one of the outlets for last year was as follows:

Revenue (500 visits)                                                                   \$200,000

Costs:

Direct labor wages (\$160 per visit)                 \$80,000

Rent and insurance                                           20,000

Income                                                                            \$(  5,000)

1. Quick Clean wants to know whether this outlet should be dropped. Identify the relevant cash flows and make a recommendation to management about this decision.
2. List one qualitative factor that might affect this type of decision.

1. List two different types of nonroutine operating decisions, and give an example of each one for a retail hardware store.

3. Describe quantitative and qualitative information, and explain why both are important in managementdecision making.
4. List two qualitative factors that need to be considered when making a decision about whether to accept a special order.
5. Donald is the sales manager of DVL Corporation. He is considering accepting a special order with a positive contribution margin.  The order would require the company to purchase special equipment.  Nevertheless, Donald estimates that the special order would contribute \$10,000 to DVL’s profits during the current quarter.  Discuss the factors that Donald should consider in deciding whether to accept the special order.
6. Nancy is the sales manager of VLP Corporation, which manufactures and sells slipcovers for household furniture. The current selling price of a slipcover is \$150.  Nancy has the opportunity to fill a special order for slipcovers at a price of \$140 each.  Describe three uncertainties that Nancy faces in making the special order decision.
7. NSL Corporation produces and sells bookcases and magazine racks. Its production operation is organized into three parts:  fabrication (where the wood and other raw materials are cut), assembly (where the cut materials are assembled into finished products), and painting (where the final products are painted and prepared for customers).  NSL is considering outsourcing one of the three functions, each of which would have an equal financial effect on the corporation overall.  Discuss why each of the following qualitative factors might be so important that it could override quantitative considerations for this decision.
8. Ability to ensure high quality
9. Timeliness of delivery
10. Whether NSL’s managers consider the function to be a core competency
11. Describe the costs that are usually relevant to a make or buy decision.
12. Describe two assumptions that need to be met when considering whether to keep or drop a product.
13. What types of opportunity costs are considered in both keep or drop and make or buy decisions?

1. Spinning Wool currently produces and sells three different types of yarn. Total demand for the yarn exceeds the firm’s capacity.  The constraint on production is the time available on a special machine that cleans the wool used for the yarn.  Data on the products and time required on the special machine are summarized in the following chart.

Type of Yarn

Fine     Medium       Coarse

Selling price                                                     \$24            \$30            \$36

Variable manufacturing cost                            \$12            \$18            \$11

Variable marketing cost                                     \$2              \$2              \$6

Fixed cost per lot                                               \$5              \$8            \$10

Machine hours needed per lot                           0.2           0.25             0.5

Maximum demand (in lots) per period          4,000         3,750         5,000

The firm has only 2,500 hours of time available on the special machine per period.  Fixed costs are \$100,000 per period, which will not change if the product mix changes or if any products are dropped.

1. Which product should Spinning Wool emphasize? Show your calculations.
2. Up to how much per hour should Spinning Wool be willing to pay to increase capacity on the special machine?
3. Describe two reasons why the managers cannot be certain that they have accurately estimated the product selling prices.

(continued on next page)

1. Describe two reasons why the managers cannot be certain that they have accurately estimated the product variable costs.
2. Discuss how the uncertainties in parts (c) and (d) are likely to affect the managers’ product emphasis decisions at Spinning Wool.

1. Franklin Manufacturing has just received an offer from a supplier to buy 12,000 units of a computerized component used in its main product. The component is currently produced internally.  The supplier has offered to sell the component for \$75 per unit.  The estimated costs of producing it are given below.

Direct materials                               \$30

Direct labor                                     \$15

Prior to making a decision, the company’s CEO commissioned a special study to see whether there would be any decrease in fixed overhead costs. The company would avoid two setups and that would reduce total spending by \$10,000 per setup.  One inspector would be laid off at a savings of \$20,000. Janitorial services would be reduced by 200 hours at \$15/hour. Although the work decreases by 200 hours, the janitor assigned to the computerized component line also spends time cleaning for other product lines and is guaranteed a 40 hour work week. Further, another department could use the area where this component is produced.  That department is currently paying \$90,000 to rent the same amount of space.

1. Ignore the special study, and determine whether the gear should be produced internally or purchased from the supplier.
2. Now repeat the analysis, using the special study data.
3. Briefly identify qualitative factors that might affect the decision, including strategic implications.

1. McVictor Industries solved the following linear programming problem as the basis for its budget for the next operating period. Fixed costs are budgeted as \$80 per unit.

Objective Function:      Maximize  \$250×Regular + \$130×Premium

Subject to:

Assembly hours constraint:

10 hours × Regular + 25 hours × Premium ≤ 10,000 hours

Testing hours constraint:

1. What quantity of each product should McVictor produce?
2. What is the contribution margin with this sales mix?
3. Suppose McVictor wants to relax the constraint in Testing. Up to what maximum amount per hour would the company be willing to pay?
4. If McVictor relaxes the constraint in Testing, will the contribution margin increase? Explain.
5. What would happen if Assembly hours decrease by more than 5,000?
6. By how much could the contribution margin of regular increase before the sales mix would change?
7. Identify reasons why the managers cannot be certain that they have accurately estimated the resource constraints.

1. Water Away produces and sells types of plastic boats. All three boats are manufactured using a single computer-controlled plastic injection molding machine.

Boat A             Boat B             Boat C

Selling price                                                \$79.00             \$99.00           \$149.00

Direct materials                                             34.00               34.00               43.00

Direct labor                                                     0.40                 0.60                 1.00

Product Margin                                     \$19.60             \$36.00             \$44.00

Computer controlled injection molder:

Machine time required per unit             0.02 hr             0.03 hr             0.05 hr

Daily demand                                    200 units         120 units           60 units

Daily machine time requirements             4 hrs             3.6 hrs                3 hrs

To meet daily demand for all three products, 10.6 hours would be required on the injection molder.  However, the machine must be attended at all times by a skilled operator who works only a standard 8-hour workday.  Therefore, insufficient capacity exists to meet demand for all three products.

The labor cost per unit is determined by multiplying the operator’s wage of \$20 per hour by the fraction of an hour required to produce a single boat.  Direct labor employees are guaranteed a 40-hour work week.  General overhead is almost entirely fixed.

1. The production bottleneck is the machine, and this bottleneck can be relaxed by inducing the skilled operator to work overtime. Up to how much should the firm be willing to pay per hour in total for the first hour of overtime?
2. The supervisor at the boat company believes that the bottleneck should be relaxed, even if the company only breaks even on the units sold after the capacity limit has been reached. Explain this reasoning.

1. Midtown Clinic provides its own housekeeping services. The clinic director would like to outsource this service, and has found a company that will provide the service for \$24 per hour.  The following information has been collected about the cost per hour to the clinic for performing its own housekeeping services:

Cost per hour of service:

Cleaning supplies                                                        \$  2

Direct labor                                                                 \$17

Total hours of housekeeping services per year               2,600

1. Should Midtown Clinic outsource housekeeping, assuming that \$26,000 of fixed costs can be eliminated if the service is outsourced? Provide calculations to support your answer.
2. At what level of service (in hours) would Midtown generally be indifferent between providing housekeeping services or outsourcing them, assuming that \$26,000 of fixed costs can be eliminated?
3. Identify one potential opportunity cost that the clinic director might have overlooked.
4. Describe two qualitative factors that might affect this outsourcing decision.

Exercises

1. a. (\$220,000 / 80,000)*10,000 units + \$10,000 = \$37,500
2. (10,000 * \$4) – \$37,500 = \$2,500 profit increase
3. a. Cost to buy = \$30 per set.

Cost to make = \$12 + \$10 + \$24 (0.3) = \$29.20 per set

Conclusion:  Make the tires

1. Extra revenue from buying = \$1,500 * 12 = \$18,000

Cost savings from making = 20,000 * (\$30.00 – \$29.20) = \$16,000

1. Will the supplier’s quality be as high as National Motor’s quality? Will deliveries be timely?  Students may have other correct responses.
2. a. Contribution margin per minute of machine time:

Wood = \$10 / 48 = \$0.208

Steel = \$11 / 50 = \$0.22

Graphite:  \$16 / 75 = \$0.213

Therefore, Speedy should produce steel rackets first, followed by graphite and wood.

1. Speedy should use 500 machine hours to produce 600 steel rackets (600 * 50 / 60).

Next, Speedy should use 625 machine hours to produce 500 graphite rackets (500 * 75 / 60).

Finally, Speedy should use the remaining 75 machine hours to produce 93 wood rackets (93 * 48 / 60).

1. The contribution margin on wood rackets, or \$0.208×60 = \$12.48/hour.
2. a. 8 x \$15 = \$120 per hour versus 5 x \$20 = \$100 per hour.  Use up 12,000/8 = 1,500 hours on Premium first.  Then the remaining 1,500 on regular.
3. Demand for regular is 21,000/5 = 4,200 hours so we can still sell it, can pay up to \$100/hour to relax constraint.
4. a. Make = \$24.50 + \$100,000/5,000 = \$44.50, so they should buy at \$40.
5. \$40 – \$24.50 = \$15.50. \$100,000/\$15.50 = 6,452 units.
6. Possible qualitative factors include quality of the subassembly and timeliness of delivery. Students may think of others.
7. a. Emphasize bike with highest contribution margin per hour.

\$400/2 versus \$500/5, so premier should be emphasized.

1. \$500/5 or \$100 per hour.
2. a. Yes, the CM/unit at \$13 is \$13 – \$11.50  = \$1.50.
3. The minimum price = VC = \$11.50
4. Here are two qualitative factors; students may have other correct responses. Will other customers learn about the price and demand a decrease?  Will costs change as the volume gets close to capacity?
5. a. \$330,000/(\$45 + 2*\$90) = 1,467 pairs of fun boots and 2,934 pairs of fancy
6. \$30,000/\$45 = 667 pairs of fun boots
7. a. Price = \$3,500/10,000 = \$0.35 plus the special cover at \$.05 = \$0.40.
8. Other considerations include the following; students may have other correct responses. Effect of special order on brand name recognition; Ability to keep ingredients fresh; Opportunity to keep employees busy during slow time
9. a. Relevant cash flows are DL, rent, variable and fixed S & A which total \$145,000.  Therefore Quick Clean contribution margin is \$200,000 – \$145,000 = \$55,000 which would be foregone if the outlet is closed.  They should keep the outlet open because they will still incur the headquarters costs, but lose \$55,000 to cover them.
10. Following are several qualitative factors; students may have other correct answers. Managers do not know whether sales from this outlet would move to other outlets of Quick Clean or to competitors.  If all sales moved to another Quick Clean outlet, the company would be better off to close this outlet.  But if most of the sales went to competitors, they would not be better off.  Will the company have any loss of reputation among customers at other outlets?  Customers may worry that their outlet will close and choose to do business elsewhere.

1. Below are examples of nonroutine operating decisions; students will think of other correct responses:

Special order – A customer wants to buy 10 snow shovels at a discounted price for a not-for-profit organization fund raising event.

Constrained resource – An item on sale has been sold out and there is still a high demand for it.

Keep or drop – A particular product, such as a specialized tool, has not been selling well and has a low contribution margin.

1. Below are actions an organization can take; students may think of other correct responses:

*      Buy more of the resource through other channels or increase capacity.

*      Substitute another process for a capacity constraint.

*      Emphasize the product with the highest contribution margin per constrained resource.

1. Quantitative information is numerical and calculations can be performed with it. Qualitative information consists of factors that are not valued numerically.  Quantitative information is important to nonroutine operating decisions because managers need to assess whether the company is likely to be better off financially with one decision alternative.  Qualitative information is important because not all factors that are relevant to a decision can be quantified.  For example, managers may be unable to reliably measure the reputation effects of closing a production facility.  In addition, qualitative factors might override the quantitative analysis.  For example, managers might choose to outsource an activity even if quantitative analyses favor insourcing, if the activity is not viewed as a core competency.
2. The following are examples of qualitative factors for a special order; students may think of others. Will regular customers want a special price if they hear about the terms of this order?  Does the company have excess capacity?  Will the order replace regular business?  Will the order improve brand name recognition?
3. Below are possible factors that Donald should consider; students may think of others:

*      General quantitative rule:  Be as well off after the special order as before it

*      Possibility of future business from this customer

*      Existence of any specialized expertise to produce

*      Alternative uses of any special-purpose equipment after order is filled

1. Below are examples of uncertainties; students will think of others:

Will this customer place additional orders in the future?

Would other customers learn about the lower price?

Will the cost of material for the special order be significantly different from regular materials costs?

Will VLP’s employees have the expertise to make the new slipcovers?

1. Ability to ensure high quality. If low quality products are delivered, NSL will have problems with quality and could lose customers or incur additional costs to improve the quality.

Timeliness of delivery.  If the products are not processed in a timely manner and production does not meet demand, customers may purchase from another company.

Core competency issues.  Most organizations want to outsource only those functions that are not core competencies.  When organizations emphasize core competencies, they should have relative advantages over competitors, and so activities that include core competencies should not be outsourced.  At the same time, managers may choose to outsource an activity that is not a core competency because they want to avoid allocating resources (including management time and effort) on activities for which they do not have a competitive advantage.

1. Variable costs and any avoidable fixed costs are relevant to a make or buy decision.
2. Following are two assumptions for keep or drop decisions; students may think of others. Other product sales will not be affected if this product is dropped.  Unavoidable fixed costs will remain constant whether or not this product is dropped.
3. The use of released capacity for other purposes must be considered for both types of decisions.
4. Average costs are not particularly useful in short-term decision making because they include fixed costs. Fixed costs generally do not change as a result of short-term decisions, making them unavoidable and irrelevant for the decision.

Problems

1. a. Following are examples of variable costs per student from a college perspective; students are likely to think of others:  Duplication, laboratory supplies
2. Following are examples of fixed costs per student from a college perspective; students are likely to think of others: Faculty salaries, utilities, depreciation
3. Contribution margin per student

Business = (\$600,000 + \$200,000) / 6,000 – \$35 = \$98.33

Engineering = (\$1,500,000 + \$500,000) / 5,000 – \$65 = \$335

Science = (\$720,000 + \$800,000) / 7,200 – \$80 = \$131.11

Humanities = (\$480,000 + \$120,000) / 4,800 – \$25 = \$100

University = \$3,689,000 / 23,000 = \$160.39

1. Profit

Business = 6,000 * (\$98.33 – \$35.00) = \$379, 980

Engineering = 5,000 * (\$335 – \$55) = \$1,400,000

Science = 7,200 * (\$131.11 – \$25.00) = \$763,992

Humanities = 4,800 * (\$100 – \$10) = \$432,000

University = \$2,975,972

1. Most likely to be dropped is Business, as it has the lowest contribution margin per student. Conversely, Engineering is the least likely to be dropped.
2. Following are uncertainties about the quantitative analyses; students may think of others:

*      Whether closure of one college will affect enrollments in other colleges

*      Whether each of the following estimates is accurate:

*      Number of majors

*      Number of non-majors taking classes

*      Revenue from student fees

*      Revenue from external grants

*      Variable cost per student

*      Whether closure would affect other funding sources, such as donations from alumni

1. Following are qualitative issues; students may think of others:

*      Need to provide students with a well-rounded education

*      Employee morale issues if one college is dropped

*      University’s overall reputation

*      Where faculty would be placed

*      Whether the college is viewed as a core competency for the university as a whole

1. a. Time needed per lot –  Fine = 12 minutes, Medium = 15 minutes, and Coarse = 30 minutes, or production per hour of special machine time – Fine = 5 lots, Medium = 4 lots, or Coarse = 2 lots.

CM/lot – Fine = \$10, Medium = \$10, and Coarse = \$19.

CM per machine hour – Fine = \$10 x 5 = \$50, Medium = \$10 x 4 = \$40, or Coarse = \$19 x 2 = \$38.

First produce Fine, then produce Medium, and lastly Coarse

1. 4,000/5 = 800 hours for Fine, then 3,750/4 = 937.5 hours for Medium, leaving 762.5 hours for Coarse which needs 5,000/2 = 2,500 hours. So we get \$38/hour for Coarse and are willing to give that up to buy more hours.
2. Following are possible uncertainties about product selling prices; students may think of others. Prices are subject to pressure from competitors, changes in consumer preferences, and economic times.  If any of these changes, expected prices could increase or decrease, depending on the nature of the change.
3. Following are possible uncertainties about product variable costs; students may think of others. Direct labor may be more or less efficient than expected.  Prices could change on direct material inputs, and variable overhead charges, such as supplies, could change because of prices changes or efficiency of use.
4. The uncertainties discussed in parts (c) and (d) are likely to have 2 major effects on product emphasis decisions. First, these uncertainties can cause the managers to emphasize products that ultimately do not turn out to be the best choices.  A product may be overemphasized if it turns out that its selling price is lower than expected or its variable costs are higher than expected.  A product may be underemphasized if the converse occurs.  Second, these uncertainties can cause managers to “hedge” their product emphasis decisions; they may not make decisions based strictly on the quantitative analysis.

1. a. Make = \$30 + \$15 + 25 = \$70.  Buy = \$75, so make.
2. Make = \$70 + ((\$10,000 + \$20,000 + \$90,000)/12,000) = \$80 so buy.
3. Following are possible qualitative factors; students may think of others. Need to consider quality of the computerized component and delivery timeliness.
4. a. 375 regular and 250 premium
5. \$12,620
6. \$24.75/hour
7. No, the contribution margin would not increase because there is a binding constraint in Assembly.
8. The optimal sales mix will change
9. \$10 per unit
10. The resource constraints assume that each unit of product can be produced for the number of estimated hours and that there will be no deviations from the expected quantity of each constrained resource. The actual use of resources and resource availability are likely to vary both due to random changes in productivity and due to unanticipated problems such as materials defects, machinery breakdowns, variations in the pace of manual work, and other factors.
11. a. \$20 per hour plus contribution margins as follows:

Boat A = \$44 x 50/hr = \$2,200,

Boat B = \$63 x  33.3/hr = \$2,098,

Boat C = 105 x 20 = \$2,100.

First produce Boat A for 4 hours, then Boat C for 3 hours, and then boat B.  Because more time could be spent on B, \$2,098 is available plus \$20 = \$2,118.

1. Brand name recognition and customer loyalty increase as more units are made and sold. If the expansion is permanent, next year the company could be better off.
2. a. Cost per hour of service if provided in-house = (\$2 + \$17 + \$1 + \$26,000/2,600) = \$30.  Outsource.
3. \$24X = \$20X + \$26,000, so X = 6,500 hours.
4. Opportunity costs could include the use of space that is now occupied by the housekeeping services.
5. The problem asks students to describe 2 qualitative factors. The textbook cites the following types of qualitative factors for outsourcing decisions:  Quality, Delivery timeliness, Ability of supplier to meet obligations, Whether activity is a core competency.  Students might describe two of these factors, or they might think of others that are relevant to the information in the problem.
