3. Key Concepts
LO1 Understand the potential effects of using externally reported product
costs for decision making.
♦ Basic approach to product costing involves assigning direct costs to products and allocating
manufacturing overhead costs to products.
• For financial reporting purposes, the product costs computed are used primarily for
developing inventory balances and cost of goods sold amounts, and are based on
traditional systems that allocate manufacturing costs using a handful of allocation bases
(e.g., direct labor, direct materials, or machine utilization).
• In a traditional system, once a predetermined overhead rate is calculated, it is applied as
if all overhead costs were variable with respect to the allocation base, which is not true in
most cases for two reasons:
(1) Some of the overhead items could be fixed, and reducing the number of units
produced does not result in lower fixed costs. Examples of such fixed costs include
cost of supervision, machine and plant depreciation, and miscellaneous items that do
not vary with the allocation base.
(2) Some of the overhead items could vary, but with cost drivers other than those
traditionally chosen ones.
• If managers attempt to recover the costs with a smaller number of units, they are likely
to meet resistance in the market, resulting in demand for even fewer units. With the
smaller production, the reported product costs increase even more.
Example 1: MCR Manufacturing is considering the introduction of a new memory card
reader for use with digital cameras. Estimated unit variable cost is $5 and annual fixed
costs would be $100,000. The managers decide to price the new product with an
industry-standard markup of 16 percent (based on full cost).
The sales are initially estimated to be 10,000 units. So the introductory price will be
$100,000
$17.4 = ($5 + ) × (1 + 16%).
10,000 units
From the recent marketing report, the sales forecast is revised downward to 8,000
units. To recover the production cost in a hurry, the managers set a newer (and higher)
price of
Instructor’s Manual Chapter 9 179
5. • The first-stage cost objects (cost pools) are the overhead accounts (e.g., machine-related
costs and direct labor-related costs) captured by the cost accounting system, as shown in
Exhibit 9.4.
• The two-stage approach separates plant, or manufacturing, overhead into two or more
cost pools based on the account in which the costs were recorded.
• The allocation in the first stage permits selection of multiple cost drivers that can be
used to allocate costs to products.
• Another common choice for first-stage cost objects is to use production departments or
product lines within the plant, as shown in Exhibit 9.5.
• The allocation of overhead costs to departments is not as simple as it is when overhead
accounts are used because the costs are not necessarily recorded at the department level.
• Complexity and special handling required during production may distort the product
costs reported when the traditional costing method is used. The two-stage system, on the
other hand, allows the firm to develop product costing systems that more closely align the
allocation of costs with the use of resources.

overhead
• The plantwide allocation method is an allocation method that uses one cost pool (of
indirect costs) for the entire plant (e.g., an entire factory, store, hospital, or other multi-
department segment of a company), as in the single stage approach mentioned earlier. It
uses one overhead allocation rate, or one set of rates, for all of the departments in a
particular plant.
• Although it is called plantwide allocation, this allocation concept can be used in both
manufacturing and nonmanufacturing organizations.
Instructor’s Manual Chapter 9 181
7. machine hour times the total number of machine-hours worked for each product.
• Companies using a single plantwide rate generally use an allocation base related to the
volume of output, such as direct labor hours, machine hours, units of output, or materials
costs.
======================
Demonstration Problem 1
ABC Manufacturing, Inc. produces three gadgets (Ace, Best, and Champ) in two departments,
Machining and Assembly. Each product requires one hour of direct labor for completion. The
following table provides production and cost data for the year.
Ace Best Champ Total
Number of units 25,000 15,000 5,000 45,000
Machine hours 2,500 1,500 2,000 6,000
Direct materials $1,000,000 $450,000 $275,000 $1,725,000
Direct labor 375,000 225,000 75,000 675,000
Overhead
Machining 900,000
Assembly 450,000
Total overhead 1,350,000
Tot costs $3,750,000
Required:
Use the plantwide allocation method to determine the unit cost for each product. The
allocation bases to choose from are
1. Machine hours.
2. Direct labor costs.
Solution:
1. The overhead allocation rate when machine hours were used as the allocation base was
$225 per machine hour (= $1,350,000 ÷ 6,000 machine hours). The unit cost report would
show the following:

Units produced 25,000 15,000 5,000
Machine hours per unit 0.1 0.1 0.4
Direct materials $40.0 $30.0 $55.0

Applied overhead ($225 per machine hour) 22.5 22.5 90.0
Unit cost $77.5 $67.5 $160.0
Instructor’s Manual Chapter 9 183
9. Required:
Use the department allocation method to determine the unit cost for each product.
Solution:
For the Machining Department, the overhead allocation rate would be $150 per machine hour
(= $900,000 ÷ 6,000 machine hours).
For the Assembly Department, the overhead allocation rate would be 66.67% (= $450,000 ÷
$675,000).

LO4 Explain how activity-based costing and a two-stage product system are
related.
♦ Activity-based costing (ABC) is a two-stage product costing method that first assigns costs to
activities and then allocates them to products based on the each product’s consumption of
activities.
• The cost pools in the two-stage approach now accumulate activity-related costs.
• An activity is any discrete task that an organization undertakes to make or deliver a
product or service.
• Activity-based costing is based on the concept that products consume activities and
activities consume resources.
• Activity-based costing can be used by any organization that wants a better
understanding of the costs of the goods and services it provides, including manufacturing,
service, and even nonprofit organizations (see In Action item for a case study).
Instructor’s Manual Chapter 9 185
11. • Cost hierarchy represents a classification of cost drivers into general levels of activity,
volume, batch, product, etc. Four possible levels of cost hierarchy are
(1) volume-related,
(2) batch-related,
(3) product-related, and
(4) facility-related.
• Exhibit 9.12 provides example of costs and cost drivers associated with each of the four
levels.
• Not all activity-based costing systems need to have all four levels in the hierarchy, and
some can have more than four. The important factor is whether the cost drivers for the
activities reflect the cost incurred by the activity.
[Assign Exercises 9-23, 9-24, 9-25, 9-26, 9-27, 9-28, 9-29]
LO5 Compute product costs using activity-based costing.
♦ In this section, the reported product costs under activity-based costing are computed in a
comprehensive example.
• Step 1: Identify the activities. A cost accountant interviewed the production manager to
determine the major activities used in the manufacturing process.
• Step 2: Identify the cost drivers. The cost accountant interviewed production
supervisors, who in turn discussed with line employees, to determine the cost
drivers and the expected volume of each driver. The information is presented in
Exhibit 9.13.
• Step 3: Compute the cost driver rates. Once the overhead costs incurred in the facility
were determined, the cost accountant calculated the cost driver rates by dividing
overhead cost by the estimated volume for each activity identified in Step 1.
Exhibit 9.14 shows the calculation.
• Step 4: Assign costs using activity-based costing. Exhibit 9.15 shows the cost flow
diagram that assigns overhead costs to activity pools in the first stage and
allocates activity costs to products in the second stage. For each product, the
direct costs (direct materials and direct labor) are the same regardless of the
costing methods used. The difference is in the assignment of overhead costs.
• There are two ways to calculate unit cost for each product.

marketing, management, and other non-accounting personnel.

Integrative Cases 9-45, 9-46, 9-47, 9-48]
LO7 Demonstrate the flow of costs through accounts using activity-based
costing.
♦ Exhibit 9.18 shows the flow of costs through accounts using activity-based costing. The
overhead accounts (both incurred and applied) are grouped by activities.
♦ Early industries were labor intensive, and much of the overhead cost was related to the support
of labor. At that time, it made sense to allocate overhead to products based on the amount of
labor component in the products.
• Nowadays, labor is still a major product cost in many companies, especially service
organizations such as consulting, law, and public accounting firms. In those cases,
overhead is often allocated to products (jobs) on the basis of the amount of labor in the
product.
• When the labor component drops in the products and overhead cost increases,
companies that continue to allocate overhead to products based on direct labor are
experiencing substantial overhead rate increases. Even small errors in cost allocation can
be magnified many times. It also sends the wrong signal that direct labor is more
expensive than it really is and drives managers to reduce the already slim labor content of
products.
• The magnitude of the overhead rate based on direct labor is of less concern when all
resources are used proportionally.
• In modern manufacturing settings, proportionality between machine hours and direct
labor hours is much less so.
♦ Costs are a function of both volume and complexity.
• Low-volume products often require more machine setups for a given level of production
output because they are produced in smaller batches.
• Low-volume product adds complexity to the operation by disrupting the production
flow of the high-volume items.
• Volume-based allocation methods allocate a high proportion of overhead costs to high-
volume products, which “subsidize” low-volume products and hide the cost effects of

27. (2) To encourage operating department managers to monitor service department costs
(cross-department monitoring).
• Each service department is an intermediate cost center whose costs are recorded as
incurred and then distributed to other cost centers.
• An important decision in cost allocation is to choose which allocation base to use. The
usual criteria (cause and effect, reasonableness, and fairness) are still important here.
[Assign Exercise 11-21]
LO2 Allocate service department costs using the direct method.
♦ Direct method is a cost allocation method that charges costs of service departments to user
departments without making allocations between or among service departments.
• The direct method allocates costs directly to the final users of a service, ignoring
intermediate users.
• Exhibit 11.4 is the cost flow diagram that illustrates the direct method.
• Using the direct method, there are no allocations between service departments. It
ignores the costs that the service departments themselves incur when they use services
from other departments. Cross-department monitoring is lost in that regard.
• The application of the direct method of cost allocation is shown in Exhibit 11.3.
• Exhibit 11.5 shows the flow of costs in T-accounts and the allocations to be recognized
for the departments when the direct method is used.
(1) The direct costs of service departments are first recorded in those service departments
and shown on the debit side of the service department accounts.
(2) Then service department costs are allocated to the user departments.
(3) The user departments also have direct costs (indicated as the direct overhead costs)
do not have to be allocated to the user departments because they are debited to the
department accounts when incurred.

Kirby Industries has two service departments (S1 and S2) and three production departments (P1,

LO3 Allocate service department costs using the step method.
♦ Step method is the method of service department cost allocation that allocates some service
department costs to other service departments.
• The step method recognizes that some services are provided by one service department
to others.
• The sequence of allocation is determined so that the allocation begins with
(1) the service department that has provided the largest proportion of its total services to
other service departments, or
(2) the service department with the largest cost.
• The percentage of service costs ignored in the step allocation process is minimized by
choosing either of the allocation orders suggested.
• Once an allocation is made from a service department, no further allocations are made
back to that department.
• A service department that provides services to, and receives services from, another
service department has only one of these two relationships recognized.
• Exhibit 11.6 shows the computation of the step method.
• Exhibit 11.7 is the cost flow diagram for the step method example.
• The flow of costs through the accounts is shown in Exhibit 11.8.

LO4 Allocate service department costs using the reciprocal method.
♦ Reciprocal method is the method to allocate service department costs that recognizes all
services provided by any service department, including services provided to other service
departments.
• The reciprocal method is identical to the actual process by which services are
exchanged among departments within organizations.
• The total costs of each service department are expressed as:
Total service Direct costs of Cost allocated
department = the service + to the service
costs department department

260,000 S2 40% - 20% 15% 25%
Required:
Allocate the service department costs to the production departments using the reciprocal
method.
Solution:
Define S1 and S2 to be the total service department costs for departments S1 and S2,
respectively.
The service department S1 incurred $1,000,000 for providing services to other departments.
The service department S2 provided 40 percent of its services to S1. Together, the total
service department costs for S1 can be expressed as:
S1 = $1,000,000 + .4 × S2.
The service department S2 incurred $260,000 for providing services to other departments.
The service department S1 provided 20 percent of its services to S2. Together, the total
service department costs for S2 can be expressed as:
S2 = $260,000 + .2 × S1.
Next, insert S1 information into S2. That is,
S2 = $260,000 + .2 × [$1,000,000 + .4 × S2].
Then,
S2 = $260,000 + $200,000 + .08 × S2.
.92 × S2 = $460,000.
S2 = $500,000.
S1 = $1,200,000.
The original service proportions will apply.

LO5 Use the reciprocal method for decisions.
♦ The primary purpose of allocating service department costs to the production departments is to
obtain the manufacturing costs for each of the production departments for product costing and
inventory valuation.
• The cost information is also developed to assist managers in making decisions, such as
whether to outsource some or all of the activities of the service departments.
• The cost savings will depend on how much an outside vendor will charge and how
much cost in the service departments can be eliminated if outsourced.
• If there are no reciprocal services among the service departments, the cost savings are
the cost of the eliminated service department that is avoidable (= variable costs + any
avoidable fixed costs).
• If there are reciprocal services, the manager has to consider the effect of eliminating one
of the service departments on the service requirements of the remaining service
departments.
• Because the reciprocal method explicitly recognizes the use of one service department
by another, it provides an estimate of what one department costs when reciprocal service
costs are included.

37. LO6 Explain why joint costs are allocated.
♦ Joint cost is a cost of a manufacturing process with two or more different outputs. Joint
products are such outputs from a common input and common production process.
• The problem is whether and how to allocate the joint cost of the input to the joint
products.
• Split-off point is the stage of processing when two or more products are separated.
Processing costs incurred prior to the split-off point are the joint costs.
Example 1: The following shows a joint production process and its joint costs. After
the split-off point, two discernable joint products, A and B, emerge from the process.
The costs before the split-off point are joint; any costs spent afterwards are separable.
Split-off point
Joint product A
Joint production
Raw process
materials (with additional
materials, labor and
overhead)
Joint product B
Joint cost
• Exhibit 11.14 shows a diagram of joint cost flows.
• Cost allocations are often used to determine departmental or division costs for
measuring executive performance.
• When a single raw material is converted into products sold by two or more departments,
the cost of the raw material must be allocated to the products involved.
• Manufacturing companies must allocate joint costs to measure the inventory value of
the products that result from the joint process.
• When companies are subject to rate regulation, the allocation of joint costs can be a
significant factor in determining the regulated rates.

M1 $200,000 20%a $90,000b
M2 300,000 30% 135,000
M3 500,000 50% 225,000
Total $1,000,000 $450,000
a
20% = $200,000 ÷ $1,000,000.
b
$90,000 = $450,000 × 20%.
======================
• If the products require further processing before they are marketable, it may be
necessary to estimate the net realizable value at the split-off point using the estimated
net realizable value method (sometimes called the netback or workback method).
Estimated Sales price of a Additional processing costs
net realizable = final product after - necessary to prepare a
value further processing product for sale
• Under the net realizable value method, revenue dollars from any joint product are
assumed to make the same percentage contribution at the split-off point as the revenue
dollars from any other joint product. That is, each joint product gets the same gross
margin percentage.
Example 2: For Demonstration Problem 5 above, the gross margin for all the joint
products can be calculated as follows.
M1 M2 M3 Total
Sales $200,000 $300,000 $500,000 $1,000,000
Allocated joint costs 90,000 135,000 225,000 450,000
Gross margin $110,000 $165,000 $275,000 $550,000
Gross margin percentage 55% 55% 55% 55%
The gross margin percentage is the same for all the joint products when the net
realizable value method is used.
• The net realizable value method implies a matching of input costs with revenues
generated by each output.
Instructor’s Manual Chapter 11 237
41. ♦ Physical quantities method allocates joint costs based on measurement of the volume, weight,
or other physical measure of the joint products at the split-off point.
• The physical quantities method is used when
(1) output product prices are highly volatile,
(2) significant processing occurs between the split-off point and the first point of
marketability, or
(3) product prices are not set by the market.
• Many companies allocate joint costs incurred in producing oil and gas on the basis of
energy equivalent (BTU content).

Demonstration Problem 7
(Continued from Demonstration Problem 5)
Superior Refinery produces oil products in a joint production process. For the month of October,
$450,000 of materials, labor and overhead were added to produce the three main products: M1,
M2, and M3. The physical quantities of the outputs are considered relevant for cost allocation
purposes. The following diagram shows the process.
M1
15,000 units
Joint costs M2
$450,000 20,000 units
M3
25,000 units
Required:
Allocate the joint costs to the products using the physical quantities method.
Solution:
The allocation of joint costs is based on the physical units in this case.
Product Units Proportion Allocation
M1 15,000 25.0%a $112,500b
M2 20,000 33.3% 150,000
M3 25,000 41.7% 187,500
Total 60,000 $450,000
Instructor’s Manual Chapter 11 239
43. M1
Sale value at the split-off point $200,000
Processing cost $120,000, New sale value $300,000
Joint costs M2
$450,000 Sale value at the split-off point $300,000
Processing cost $80,000, New sale value $400,000
M3
Sale value $500,000
Required:
Determine whether to sell M1 and M2 right after the split-off point, or process them further
to be sold at higher prices.
Solution:
Additional profit
Product Sale value at Sale value after Processing Margin from processing
split-off point processing cost further
(1) (2) (3) (4) = (2) – (3) (4) – (1)
M1 $200,000 $300,000 $120,000 $180,000 $(20,000)
M2 300,000 400,000 80,000 320,000 20,000
Processing M1 further will reduce profit by $20,000 while processing M2 further will
increase profit by $20,000. It is beneficial to sell M1 right after the split-off point and process
M2 further to improve revenue.

LO10 Account for by-products.
♦ By-products are outputs from a joint production process that are relatively minor in quantity
and/or value when compared to the main products.
• By-product accounting attempts to reflect the economic relationship between the by-
products and the main products with a minimum of recordkeeping for inventory valuation
purposes.
• Two common methods of accounting for by-products are:
Instructor’s Manual Chapter 11 241
45. Solution:
There are two methods of accounting for by-products. The first method deducts the net
realizable value from sale of the by-products from the cost of the main products, as shown
below.
Total costs to be allocated = Joint costs – Net realizable value from the by-product, or
$420,000 = $450,000 - $30,000.
Product Sale value Proportion Allocation
M1 $200,000 20%a $84,000b
M2 300,000 30% 126,000
M3 500,000 50% 210,000
Total $1,000,000 $420,000
a
20% = $200,000 ÷ $1,000,000.
b
$84,000 = $420,000 × 20%.
The second method treats the proceeds from sale of the by-product as other revenue. The
joint costs will be allocated to the main products without adjustment, as in Demonstration
Problem 5.

LO11 (Appendix) Use spreadsheets to solve reciprocal cost allocation
problems.
♦ The reciprocal method requires that cost relationships be written in equation form. The method
then solves the equations for the total costs to be allocated to each department.
• For any department (both service and production), the following equation applies:
Total costs = Direct costs + Allocated costs.
• The total costs are the unknowns that will be solved.
• The analysis can be expanded to any number of service departments and production
departments.
• The set of equations can be rewritten and expressed in matrix form, and solved using
the matrix functions of a spreadsheet program such as Microsoft Excel.
• The process has three steps:
