Basic Cost Management Concepts
ANSWERS TO REVIEW QUESTIONS
2-1 Product costs are costs that are associated with manufactured goods. They are
assets until the time period during which the products are sold, when the product
costs become expenses. Period costs are expensed during the time period in which
they are incurred.
2-2 Product costs are also called inventoriable costs because they are assigned to
manufactured goods that are inventoried until a later period, when the products are
sold. The product costs remain in the Work-in-Process or Finished-Goods Inventory
account until the time period when the goods are sold.
2-3 The most important difference between a manufacturing firm and a service industry
firm, with regards to the classification of costs, is that the goods produced by a
manufacturing firm are inventoried, whereas the services produced by a service
industry firm are consumed as they are produced. Thus, the costs incurred in
manufacturing products are treated as product costs until the period during which
the goods are sold. Most of the costs incurred in a service industry firm to produce
services are operating expenses that are treated as period costs.
2-4 The five types of production processes are as follows:
Job shop: Low production volume; little standardization; one-of-a-kind
products. Examples include custom home construction, movie production,
and ship building.
Batch: Multiple products; low volume. Examples include construction
equipment, tractor trailers, and cabin cruisers.
Assembly line: A few major products; higher volume. Examples include
kitchen appliances and automobile assembly.
Mass customization: High production volume; many standardized
components; customized combination of components. Examples include the
computer industry and custom textbooks.
Continuous flow: High production volume; highly standardized commodity
products. Examples include food processing, textiles, lumber, and
chemicals.
Chapter 02 – Basic Cost Management Concepts
2-5 The term mass customization is used to describe an industry such as the computer
industry, where large numbers of identical components are mass produced, and then
these components are combined in a customized way to customer specifications.
For example, when a customer places an order for a Dell computer via the internet,
the company assembles just the components requested by the customer, loads the
requested software, and ships the customized computer system. Viewed in this
light, the term mass customization is not internally inconsistent.
2-6 The cost of idle time is treated as manufacturing overhead because it is a normal
cost of the manufacturing operation that should be spread out among all of the
manufactured products. An alternative to this treatment would be to charge the cost
of idle time to a particular job that happens to be in process when the idle time
occurs. Idle time often results from a random event, such as a power outage.
Charging the cost of the idle time resulting from such a random event only to the job
that happened to be in process at the time would overstate the cost of that job.
2-7 Overtime premium is included in manufacturing overhead in order to spread the
extra cost of the overtime over all of the products produced, since overtime often is
a normal cost of the manufacturing operation. The alternative would be to charge the
overtime premium to the particular job in process during overtime. In most cases,
such treatment would overstate the cost of that job, since it is only coincidental that
a particular job happened to be done on overtime. The need for overtime to complete
a particular job results from the fact that other jobs were completed during regular
hours.
2-8 The phrase “different costs for different purposes” refers to the fact that the word
“cost” can have different meanings depending on the context in which it is used.
Cost data that are classified and recorded in a particular way for one purpose may be
inappropriate for another use.
2-9 A city would use cost information for planning when it developed a budget for its
operations during the next year. Included in that budget would be projected costs for
police and fire protection, street maintenance, and city administration. At the end of
the year this budget would be used for cost control. The actual costs incurred would
be compared to projected costs in the budget. City administrators would also use
cost data in making decisions, such as where to locate a new fire station.
2-10 A fixed cost remains constant in total across changes in activity, whereas the total
variable cost changes in proportion to the level of activity.
2-11 The fixed cost per unit declines as the level of activity (or cost driver) increases. The
cost per unit is reduced because the total fixed cost, which does not change as
activity changes, is spread over a larger number of activity units.
Chapter 02 – Basic Cost Management Concepts
2-12 The variable cost per unit remains constant as the level of activity (or cost driver)
changes. Total variable costs change in proportion to activity, and the additional
variable cost when one unit of activity is added is the variable cost per unit.
2-13 A volume-based cost driver, such as the number of passengers, causes costs to be
incurred because of the quantity of service offered by the airline. An operations-
based cost driver, such as hub domination, affects costs because of the basic way in
which the airline conducts its operations. Greater control over a hub airport’s
facilities and services gives an airline greater ability to control its operating costs.
2-14 a. Number of students: volume-based cost driver. This characteristic of the college
relates to the quantity of services provided.
b. Number of disciplines offered for study: operations-based cost driver. The
greater the diversity in a college’s course offerings, the greater will be the costs
incurred, regardless of the overall size of the student body.
c. Urban versus rural location: operations-based cost driver. A college’s location
will affect the type of housing and food facilities required, the cost of obtaining
services, and the cost of transportation for college employees acting on behalf of
the college.
2-15 Examples of direct costs of the food and beverage department in a hotel include the
money spent on the food and beverages served, the wages of table service
personnel, and the costs of entertainment in the dining room and lounge. Examples
of indirect costs of the food and beverage department include allocations of the
costs of advertising for the entire hotel, of the costs of the grounds and maintenance
department, and of the hotel general manager’s salary.
2-16 Costs that are likely to be controllable by a city’s airport manager include the wages
of personnel hired by the airport manager, the cost of heat and light in the airport
manager’s administrative offices, and the cost of some materials consumed in the
process of operating the airport, such as cleaning, painting, and maintenance
materials. Costs that are likely to be uncontrollable by the city’s airport manager
include depreciation of the airport facilities, fees paid by the airport to the federal
government for air traffic control services, and insurance for the airport employees
and patrons.

c. Uncontrollable cost
2-18 Out-of-pocket costs are paid in cash at or near the time they are incurred. An
opportunity cost is the potential benefit given up when the choice of one action
precludes the selection of a different action.
2-19 A sunk cost is a cost that was incurred in the past and cannot be altered by any
current or future decision. A differential cost is the difference in a cost item under
two or more decision alternatives.
2-20 A marginal cost is the extra cost incurred in producing one additional unit of output.
The average cost is the total cost of producing a particular quantity of product or
service, divided by the number of units of product or service produced.
2-21 The process of registering for classes varies widely among colleges and
universities, and the responses to this question will vary as well. Examples of
information that might be useful include the credit requirements and course
requirements to obtain a particular degree, and a list of the prerequisites for each of
the elective courses in a particular major. Such information could help the student
plan an academic program over several semesters. An example of information that
might create information overload is a comprehensive listing of every course offered
by the college in the past five years.
2-22 (a) The purchase cost of the old bar code scanners is a sunk cost, since it occurred
in the past and cannot be changed by any future course of action. (b) The manager is
exhibiting a common behavioural tendency to pay too much attention to sunk costs.

Mass customization is well suited to Dell Computer’s operations because of the company’s
direct-selling approach, in which customers order customized computer systems, often via
the internet. Then Dell orders just the components necessary to assemble the computer
systems that have been ordered, and delivery is made in a relatively short period of time.

EXERCISE 2-35 (10 MINUTES)
1. Your decision to see the game really cost you $100, the amount forgone when you
refused to sell the ticket. A convenient way to think about this is as follows: You
could have sold the ticket for $100, thereby resulting in a profit on the deal of $40
($100 sales proceeds minus $60 out-of-pocket purchase cost). Instead, you went to
the game, which left you relieved of your $60 out-of-pocket cost. The difference
between the $60 reduction in your wealth and the $40 profit you could have had is
$100. Thus, $100 is the true cost of going to the game.
2. The $100 is an opportunity cost. At the time you made the decision to attend the
game, the $60 you actually had paid for the ticket is a sunk cost. It is not relevant to
any future decision.

1. The marginal cost would include any food and beverages consumed by the
passenger and perhaps an imperceptible increase in fuel costs.
2. In most cases, only the cost of the food and beverage consumed by the customer
would be a marginal cost. It is unlikely that the restaurant would need to employ
additional service personnel, dishwashers, and so on.
3. The marginal cost of a flight would include the aircraft fuel, wages of the flight crew
and airport maintenance personnel, and the food and beverages consumed by the
passengers and crew.
4. The marginal cost would include the additional wages or commissions earned by the
branch bank employees and the additional electricity used for light, heat, and
computer equipment.
5. The marginal cost of the skis would include the direct material. It is unlikely that
labour and other costs would change with the addition of only one more product

2. The asset that differs among these businesses is inventory. Service businesses
typically carry no (or very little) inventory. Retailers and wholesalers normally stock
considerable inventory. Manufacturers also carry significant inventories, typically
subdivided into three categories: raw material, work in process, and finished-goods.
3. The income statements of service businesses normally have separate sections for
operating revenues, operating expenses, and other income (expenses). In contrast,
income statements of retailers, wholesalers, and manufacturers disclose sales
revenue, followed immediately by cost of goods sold and gross margin. Operating
expenses are listed next followed by other income (expenses).
4. The basic difference falls in the area of inventory. Traditional manufacturers
produce finished goods, which are then placed in warehouses awaiting sale. In
contrast, with a direct-sales, mass-customization firm, the receipt of a sales order
triggers the manufacturing process as well as the purchasing system, the latter to
acquire needed raw materials. Finished-goods and raw-material inventories (along
with work in process) of mass-customizers are, therefore, much lower than the
inventories carried by traditional firms.

Since gross margin equals 30% of sales, cost of goods sold equals 70% of sales, or
$231,000 ($330,000 x 70%). Thus, the finished goods destroyed by the fire cost $44,000,
computed as follows:
Finished-goods inventory, Jan. 1 (given)…………….. $ 37,000
Add: Cost of goods manufactured*…………………… 238,000
Cost of goods available for sale (given)……………… $275,000

Cost of goods sold (calculated above)……………….. $231,000
*Fill in these blanks, given the other numbers in this table.
Direct material used:
Direct material averages 25% of prime costs (i.e., direct material + direct labour).
Thus: Let X = direct material used
X = (X + $120,000) x 25%
X = 0.25X + $30,000
0.75X = $30,000
X = $40,000
Manufacturing overhead:
Manufacturing overhead equals 50% of total production costs.
Thus: Let Y = manufacturing overhead
Y = (direct material used + direct labour + manufacturing overhead) x 50%
Y = ($40,000 + $120,000 + Y) x 50%
Y = $20,000 + $60,000 + 0.50Y
0.50Y = $80,000

constant.
(b) No change. Despite the decrease in the number of units produced, this is a
