ANSWERS TO QUESTIONS
1. Direct labor is a valid basis for allocating overhead when: (a) direct labor constitutes a significant part of total product cost, and (b) there is a high correlation between direct labor and changes in the amount of overhead costs.
2. The amount of direct labor in many industries has greatly decreased, due to advances in computerized systems, technological innovation, global competition and automation. Total overhead costs resulting from depreciation on expensive equipment and machinery, utilities, repairs, and maintenance have significantly increased. Many companies now use machine hours as the basis on which to allocate overhead in an automated manufacturing environment.
3. In many automated manufacturing environments, machine hours is a more relevant basis on which to allocate overhead.
4. Under a traditional volume-based costing system where overhead cost is allocated on the basis of units of output, the high-volume product will undoubtedly absorb more overhead than the lowvolume product.
5. The principal differences are:
(1)
(2)
Primary focus Bases of allocation
Activity-Based Costing Traditional Costing
Activities performed in making products
Multiple cost drivers
Units of production
Single unit-level base
6. Activity-based overhead rates are computed using the following formula:
Estimated
Expected
7. The four steps involved in developing an ABC system are:
1. Identify and classify the major activities involved in the manufacture of specific products, and allocate manufacturing overhead costs to appropriate cost pools.
2. Identify the cost driver that has a strong correlation to the costs accumulated in the cost pool.
3. Compute the overhead rate for each cost driver.
4. Assign manufacturing overhead costs for each cost pool to products, using the overhead rates (cost per driver).
8. A value-added/non-value-added activity flowchart is based on a systematic analysis of all the activities (resource-consuming actions and transactions) performed to manufacture a product or render a service. The flowchart documents each activity and the time involved in each activity. The flow chart also documents management’s proposed reengineering of the manufacturing process.
9. An activity cost pool is the overhead cost attributed to a distinct type of activity.
10. A cost driver is any factor or activity that has a direct cause-effect relationship with the resources consumed.

Overhead per
Activity
Use of Cost Drivers per Activity
11. A cost driver is accurate and appropriate if it measures the actual consumption of the activity in manufacturing a product or rendering a service and the data relating to the cost driver is available and easily obtained.
12. The formula for assigning activity cost pools to products is:
Activity-based overhead rate X Expected use of cost drivers per product
13. The primary benefit of ABC is more accurate product costing. This results from using more cost pools and enhanced control over overhead costs, and leads to better management decisions.
14. The limitations of ABC are: (a) increased costs that accompany multiple-activity cost pools and cost drivers and (b) the necessity still to allocate some costs arbitrarily.
15. ABC is the superior costing system when: (1) product lines differ greatly in volume and manufacturing complexity; (2) product lines are numerous, diverse, and require differing degrees of support services; (3) overhead costs constitute a significant portion of total costs; (4) the manufacturing process or the number of products has changed significantly; and (5) data from the existing system is being ignored.
16. Basic ABC has been enhanced by identifying activities as value-added and non-value-added.
17. Identifying non-value-added activities highlights for managers the activities that should be reduced or eliminated because they are not essential and they add no value to the product.
18. The overall objective of ABC in service firms is no different than for manufacturing companies; that is, improved costing of services rendered (by job, service, contract, or customer). The general approach to costing is the same—analyze operations, identify activities, assign overhead costs to activity cost pools, and identify and use cost drivers to assign the cost pools to the services.
19. Greater accuracy in cost allocation is achieved by recognizing the four levels of activity. Some activities are affected (driven) by changes in the number of units produced, while other activities are affected only by changes in the number of batches or the number of products, and some, facility-level activities, are unaffected by changes in either units, batches, or products produced
*20. (a) Just-in-time processing has a just-in-time philosophy and a pull approach to eliminate inventory. It is dedicated to having the right amount of materials, parts, or products just as they are needed.
(b) There are three important elements in JIT processing:
(1) A company must have dependable suppliers who are willing to deliver on short notice exact quantities of raw materials according to precise quality specifications.
(2) A multiskilled workforce must be developed.
(3) A total quality control system must be established.

SOLUTIONS TO BRIEF EXERCISES
BRIEF EXERCISE 17-1
(a) Estimated annual overhead costs = Predetermined overhead rate Expected annual operating activity
$975,000 = $9.75 per direct labor hour 100,000
(b) 92,000 direct labor hours X $9.75 = $897,000 overhead applied
(c) If the manufacturing process is complex, then multiple allocation bases can result in more accurate product-cost computations. In such situations, managers need to consider an overhead cost allocation method that uses multiple bases. That method is activitybased costing.
BRIEF EXERCISE 17-2
Under ABC, overhead costs are shifted from the high-volume products to the low-volume products. This shift results in more accurate costing for two reasons:
1. Low-volume products often require more special handling, such as more machine setups and inspections, than high-volume products. Thus, the low-volume product frequently is responsible for more overhead costs per unit than is a high-volume product.
2. Assigning overhead using ABC will usually increase the cost per unit for low-volume products. Therefore, a traditional overhead allocation such as direct labor hours is usually a poor cost driver for assigning overhead costs to low-volume products.
As a result, for Finney, one of the products (Product RX3) may have been low volume and therefore may have more overhead costs assigned to it under an ABC system.

Re: Benefits of activity-based costing (ABC)
ABC focuses on the activities performed in producing a product. Overhead costs are assigned to products based on cost drivers that measure the activities performed on the product.
The primary benefit of ABC is more accurate and meaningful product costing. This improved cost data can lead to reduced costs as managers become more aware of the underlying causes of cost incurrence. Thus, control over costs is enhanced.
Theimproved costdatashouldalso lead tobettermanagementdecisions. More accurate product costing should contribute to setting selling prices which will help achieve desired profitability levels. In addition, it should be helpful in deciding whether to make or buy a product part or component, and sometimes even whether to eliminate a product.

(c) Assuming that the cost drivers are a reasonable representation of what is occurring in the two product lines, it seems appropriate to switch to activity-based costing. By using this system, more accurate cost information is developed which should lead to better allocations of resources and more informative pricing decisions in the future.

(d) The amount of overhead allocated to the average residential job under activity based costing would be:
(e) The amount of overhead allocated to the average residential job under traditional costing is $14, versus $8.60 under ABC. This means that too much overhead is being allocated to residential jobs, and too little to commercial jobs under traditional costing. This would make the residential jobs appear less profitable than they actually are, and would overstate the profitability of the commercial jobs.

(f) (1) Activity-based costing shows the commercial model absorbs nearly 21/2 ($48.80 ÷ $20.12) times as much overhead per unit as the home model.
(2) The comparison of ABC and traditional costing shows that the proper amount of overhead assigned to the two products is not equal at $24.68 but rather $20.12 for the home model and $48.80 for the commercial model. Under traditional costing, the margin of error on the commercial model was almost 100%, an understatement of $24.12 on an assignment of $24.68. These distorted overhead assignments have likely led to overpricing the home model and underpricing the commercial model.

Activity-based costing is the preferable costing system for setting prices because the real costs are more accurately reflected. The greater accuracy is a result of multiple, more relevant activity cost drivers under ABC than the single cost driver used with the traditional volume-based system.

From: Student
Subject: Product costs using traditional approach versus ABC
The memorandum covers the following points:
a. ABC allocates overhead costs as a function of each product’s use of cost drivers. Thus, ABC results in overhead allocation that more closely approximates each product’s generation of overhead costs.
b. Traditional approaches that allocate costs as a function of volume tend to be biased toward allocating too much overhead to high volume, simple products, and too little to low volume, complex products. This is because the actual incurrence of overhead costs is rarely correlated with labor costs.
c. In the case of the Benton Corporation, the LiteMist product required the company to begin using more complex methods and equipment. Overhead costs increased substantially. When overhead costs were allocated using labor rates, too much overhead was allocated to the high volume CoolDay product. This reduced the apparent profitability of this product.

(d) Activity-based costing permits the company to identify its R&D costs by the activities that cause the costs; that is, ABC allows closer scrutiny of the causes for cost incurrences; hence, greater control. By charging inhouse manufacturing departments for their fair share of the company’s R&D costs, these departments may exert their own control over such costs. Activity-based costing allows Ideal to compile realistic costs for bidding and charging outside users of its R&D department’s services.

(a) Some of the benefits of ABC for the financial services industry include:
Identification of the most profitable customers
More accurate product and service pricing
Increased product profitability
Well-organized process costs
(b) Three things that the company’s original costing method did not take into account were:
(1) The same servicing and administrative expenses were applied equally to all accounts, including fixed and adjustable rate mortgages.
(2) No consideration was given to “seasoning”, that is, the amount of time a loan had been on the books.
(3) It did not take credit quality into account.
(c) Some of the cost drivers used under the new approach were:
Average number of accounts that were at least 60 days delinquent.
Average number of accounts outstanding.
Average number of bankrupt accounts plus the average number of real estate owned accounts.

(a) According to the authors, “ABC loses power in large-scale operations, and can be difficult to implement and maintain.” They suggest, though, that ABC should not be abandoned but, rather, improved because it provides many potential benefits.
They cite as benefits that ABC “has helped many companies identify important cost- and profit-enhancement opportunities through repricing of unprofitable customer relationships, process improvement on the shop floor, lower-cost product designs, and rationalized product variety.”
(b) One way to estimate practical capacity is to simply use a rule of thumb, such as practical capacity is 80 to 85% of theoretical capacity. The authors suggest that estimates for people be put at the lower end of the range and for machines at the upper end of the range. A more systematic approach would be to review past activity levels during a month where a high level of orders was processed with a high degree of success.
The authors say that it is not important to be extremely precise, as long as you are within 5 to 10% of the actual number.
(c) After practical capacity is determined in terms of total time available, the cost per unit of time is determined by dividing the total cost of that capacity by the total capacity in units of time. This results in a cost per unit of time. Next, managers determine the amount of time it takes to carry out each type of activity. Then the cost per time unit can be multiplied by the time it takes to perform each activity so that the cost of the activity is determined. This then enables the company to assign costs to the activities performed for specific customers or in making specific products.

(d) One of the primary benefits of the report provided by “ABC, the TimeDriven Way” is that it highlights the difference between capacity supplied and capacity used. This enables management to evaluate its effectiveness in its use of the company’s resources and to evaluate decisions regarding increasing or decreasing capacity.
As an example, the authors discuss the experience of Lewis-Goetz, a hose and belt fabricator. It found that one of its plants was operating at only 27% of capacity. It was able to use this information in making decisions regarding how it planned to meet the production requirements of a very large order it was anticipating for later in the year.
