CHAPTER 7 SUPPORT-DEPARTMENT COST ALLOCATION QUESTIONS FOR WRITING AND DISCUSSION 1. Stage one assigns support-department costs to producing departments. Costs are assigned using factors that reflect the consumption of the services by each producing department. Stage two allocates the costs assigned to the producing departments (including service costs and direct costs) to the products passing through the producing departments. 2. Support-department costs are part of the cost of producing a product. Knowing the individual product costs is helpful for developing bids and cost-plus prices. 3. GAAP require that all manufacturing costs be assigned to products for inventory valuation. 4. Allocating support-department costs makes users pay attention to the level of service activity consumed and also provides an incentive for them to monitor the efficiency of the support departments. 5. Without any allocation of supportdepartment costs, users may view services as a free good and consume more of the service than is optimal. Allocating supportdepartment costs would encourage managers to use the service until such time as the marginal cost of the service is equal to the marginal benefit. 6. Since the user departments are charged for the services provided, they will monitor the performance of the support department. If the service can be obtained more cheaply externally, then the user departments will be likely to point this out to management. Knowing this, a manager of a support department will exert effort to maintain a competitive level of service. 7. The identification and use of causal factors ensures that support-department costs are accurately assigned to users. This increases the legitimacy of the control function and enhances product costing accuracy. 8. a. Number of employees; b. Square footage; c. Pounds of laundry; d. Orders processed; e. Maintenance hours worked; f. Number of employees; and g. Number of transactions processed.

9. Allocating actual costs passes on the efficiencies or inefficiencies of the support department, something which the manager of the producing department cannot control. Allocating budgeted costs avoids this problem. 10. The direct method allocates the direct costs of each support department directly to the producing departments. No consideration is given to the fact that other support departments may use services. The sequential method allocates support-department costs sequentially. First, the costs of the center providing the greatest service to all user departments, including other support departments, are allocated. Next the costs of the second greatest provider of services are allocated to all user departments, excluding any department(s) that has already allocated costs. This continues until all supportdepartment costs have been allocated. The principal difference in the two methods is the fact that the sequential method considers some interactions among support departments and the direct method ignores interactions. 11. Yes, the reciprocal method is more accurate because it fully considers interactions among support departments. However, the reciprocal method is much more complex and can be difficult for managers to understand. If the results are similar, the simpler method should be used. 12. A joint cost is a cost incurred in the simultaneous production of two or more products. At least one of these joint products must be a main product. It is possible for the joint production process to produce a product of relatively little sales value relative to the main product(s); this product is known as a by-product. 13.

Joint costs occur only in cases of joint production. A joint cost is a common cost, but a common cost is not necessarily a joint cost. Many overhead costs are common to the products manufactured in a factory but do not signify a joint production process.

The use of number of legal hours as the charging base is much better than the number of apartment units. The number of legal hours is directly associated with the attorney’s charges. The number of units is, apparently, a poor proxy for the use of legal services. Two problems are immediately evident. First, the use of the unit charge means that Stewart will only be charging actual legal fees when the number of units times the per-unit rate happens to equal the number of hours times the per-hour rate. In this case, he will not recoup all of his spending on legal fees. That occurred here, where Stewart charged the owners only $8,000 for legal fees, but paid the attorney $10,400. In other years, the amount charged the apartment owners will be more than the amount charged by the attorney. Second, it is possible for apartment owners to have a smaller or larger proportion of units than of hours. Even in the example above, we can see that Elm Street has a small percentage of units, but causes a larger proportion of legal fees.

7–7 1.

$460 = $46 × number of hours of maintenance Number of hours of maintenance = 10 hours The controller must have looked up the usage of maintenance by the Assembly Department, found that it had used 10 hours, and multiplied those hours by the single charging rate of $46. In that case, $460 would be correct.

2.

Rate for routine maintenance = $48,000/2,000 = $24/routine maint. hour Rate for technical maintenance = $145,200/2,200 = $66/tech. maint. hour New charge for Assembly Department = $24 × 10 routine hours = $240

3.

When single charging rates are used by companies, they must be aware that changes in the way work is performed may require changes in the charging rate(s). In this case, the additional complexity caused by the computer-controlled equipment means that a single charging rate does not adequately control for the differences in cost caused by different departments. Multiple charging rates do a better job of charging the using department for the resources provided by the support departments.

Yes, there is a difference in the bids. Ranking Maintenance first results in a higher dollar allocation to Power ($120,000) than the allocation from Power to Maintenance ($40,000). Then, the greater usage of Power by Assembly results in a higher allocation to Assembly when Maintenance is ranked first. Thus, the ranking of Maintenance first gives a greater chance for support-department interaction to be reflected in the ultimate overhead rates. (These results can be compared with the results using the reciprocal method in Problem 7–26.)

The difference in price is over $500. This amount could be significant, depending on the competitive conditions facing the firm. Assuming that the sequential method provides more accurate cost assignments, this method should be used if the increased accuracy is important for the firm’s well-being. Otherwise, the firm should use the much simpler direct method.

Method 2 allocates cost on the basis of the cost driver which causes it and would be more likely to encourage managers to use Purchasing Department time efficiently. Method 1 assigns purchasing costs according to a base that may not be causally related. Therefore, an apartment complex with stable rentals from one year to the next may still experience wild fluctuations in allocated cost due to changing rental patterns of other apartment complexes.

50,725 $152,175 ÷ 1,500 $ 101.45

Although the difference is small, it appears to make the bids more attractive. 3.

The use of the sequential method to allocate support-department costs to producing departments gives more accurate overhead rates.

4.

If the best competing bid was $4.10 lower than the original bid, then it would be $14.65. In this case, the sequential method of allocating overhead costs would provide a bid ($14.63) that is just below the competing bid. Since the sequential method is more accurate, the $14.63 bid is a good one.

MANAGERIAL DECISION CASES 7–32 1.

Emma’s argument about the arbitrary nature of allocations has little merit. Even if the allocation is arbitrary, changing it to exploit a customer is wrong. Many allocations, however, are based on causal factors and reflect the consumption of resources. If we accept cause and effect as a reasonable criterion for allocation, then switching to a factor that is less related to overhead consumption certainly will increase the inaccuracy of the product cost. Emma should price the new order using the most accurate cost information available. Thus, the current allocation scheme should be maintained.

2.

The controller (Lenny) should refuse to change the allocation method and make every attempt to tactfully convince Emma of the impropriety of the recommended action. Often, a simple comment questioning the propriety of an action is sufficient to dissuade. According to the IMA Statement of Ethical Professional Practice, accountants should “refrain from engaging in any conduct that would prejudice carrying out duties ethically.” (III-2) The accountant should also abstain from engaging in or supporting any activity that might discredit the profession. (III-3) By changing allocation procedures, the controller would obtain personal gain (a bonus) from unethical means. Furthermore, Lenny has an obligation to communicate information fairly and objectively (IV-1). Choosing an allocation method that is known to be less accurate is not consistent with this requirement.

3.

Lenny should pursue all levels of internal review until a satisfactory resolution is achieved. Then, after exhausting all levels of internal review, Lenny should submit his resignation.

4.

Reacting with anger and contacting the customer was not an appropriate action (as defined by the code for management accountants). According to the code, “Except where legally prescribed, communication of such problems to authorities or individuals not employed or engaged by the organization is not considered appropriate.”
