CHAPTER 17
PROCESS COSTING
17-1 Industries using process costing in their manufacturing area include chemical processing,
oil refining, pharmaceuticals, plastics, brick and tile manufacturing, semiconductor chips,
beverages, and breakfast cereals.
17-2 Process costing systems separate costs into cost categories according to the timing of
when costs are introduced into the process. Often, only two cost classifications, direct materials
and conversion costs, are necessary. Direct materials are frequently added at one point in time,
often the start or the end of the process, and all conversion costs are added at about the same
time, but in a pattern different from direct materials costs.
17-3 Equivalent units is a derived amount of output units that takes the quantity of each input
(factor of production) in units completed or in incomplete units in work in process, and converts
the quantity of input into the amount of completed output units that could be made with that
quantity of input. Each equivalent unit is comprised of the physical quantities of direct materials
or conversion costs inputs necessary to produce output of one fully completed unit. Equivalent
unit measures are necessary since all physical units are not completed to the same extent at the
same time.
17-4 The accuracy of the estimates of completion depends on the care and skill of the
estimator and the nature of the process. Semiconductor chips may differ substantially in the
finishing necessary to obtain a final product. The amount of work necessary to finish a product
may not always be easy to ascertain in advance.
17-5 The five key steps in process costing follow:
Step 1: Summarize the flow of physical units of output.
Step 2: Compute output in terms of equivalent units.
Step 3: Compute cost per equivalent unit.
Step 4: Summarize total costs to account for.
Step 5: Assign total costs to units completed and to units in ending work in process.
17-6
Three inventory methods associated with process costing are:
 Weighted average.
 First-in, first-out.
 Standard costing.
17-7 The weighted-average process-costing method calculates the equivalent-unit cost of all
the work done to date (regardless of the accounting period in which it was done), assigns this
cost to equivalent units completed and transferred out of the process, and to equivalent units in
ending work-in-process inventory.
17-1
17-8 FIFO computations are distinctive because they assign the cost of the previous
accounting period’s equivalent units in beginning work-in-process inventory to the first units
completed and transferred out of the process and assigns the cost of equivalent units worked on
during the current period first to complete beginning inventory, next to start and complete new
units, and finally to units in ending work-in-process inventory. In contrast, the weighted-average
method costs units completed and transferred out and in ending work in process at the same
average cost.
17-9 FIFO should be called a modified or departmental FIFO method because the goods
transferred in during a given period usually bear a single average unit cost (rather than a distinct
FIFO cost for each unit transferred in) as a matter of convenience.
17-10 A major advantage of FIFO is that managers can judge the performance in the current
period independently from the performance in the preceding period.
17-11 The journal entries in process costing are basically similar to those made in job-costing
systems. The main difference is that, in process costing, there is often more than one work-inprocess account––one for each process.
17-12 Standard-cost procedures are particularly appropriate to process-costing systems where
there are various combinations of materials and operations used to make a wide variety of similar
products as in the textiles, paints, and ceramics industries. Standard-cost procedures also avoid
the intricacies involved in detailed tracking with weighted-average or FIFO methods when there
are frequent price variations over time.
17-13 There are two reasons why the accountant should distinguish between transferred-in
costs and additional direct materials costs for a particular department:
(a) All direct materials may not be added at the beginning of the department process.
(b) The control methods and responsibilities may be different for transferred-in items and
materials added in the department.
17-14 No. Transferred-in costs or previous department costs are costs incurred in a previous
department that have been charged to a subsequent department. These costs may be costs
incurred in that previous department during this accounting period or a preceding accounting
period.
17-15 Materials are only one cost item. Other items (often included in a conversion costs pool)
include labor, energy, and maintenance. If the costs of these items vary over time, this variability
can cause a difference in cost of goods sold and inventory amounts when the weighted-average
or FIFO methods are used.
A second factor is the amount of inventory on hand at the beginning or end of an
accounting period. The smaller the amount of production held in beginning or ending inventory
relative to the total number of units transferred out, the smaller the effect on operating income,
cost of goods sold, or inventory amounts from the use of weighted-average or FIFO methods.

3.
The difference in the Assembly Department cost per unit calculated in requirements 1 and
2 arises because the costs incurred in January and February are the same but fewer equivalent
units of work are done in February relative to January. In January, all 10,000 units introduced are
fully completed resulting in 10,000 equivalent units of work done with respect to direct materials
and conversion costs. In February, of the 10,000 units introduced, 10,000 equivalent units of
work is done with respect to direct materials but only 9,500 equivalent units of work is done with
respect to conversion costs. The Assembly Department cost per unit is, therefore, higher.

The calculations of equivalent units for direct materials and conversion costs are identical
to the calculations of equivalent units under the FIFO method. Solution Exhibit 17-25A shows
the equivalent unit calculations for standard costing given by the equivalent units of work done
in July 2007. Solution Exhibit 17-26 uses the standard costs (direct materials, $6.60; conversion
costs, $10.40) to summarize total costs to account for, and to assign these costs to units
completed and transferred out and to units in ending work-in-process inventory.

The cost per equivalent unit differs between the two methods because each method uses different
costs to calculate the numerator of the calculation. FIFO uses only the costs added during the
period whereas weighted-average uses the costs from the beginning work-in-process as well as
costs added during the period. Both methods also use different equivalent units in the
denominator.
The following table summarizes the costs assigned to units completed and those still in
process under the weighted-average and FIFO process-costing methods for our example.

$3,515,000
The FIFO ending inventory is higher than the weighted-average ending inventory by
$4,866. This is because FIFO assumes that all the lower-cost prior-period units in work in
process are the first to be completed and transferred out while ending work in process consists of
only the higher-cost current-period units. The weighted-average method, however, smoothes out
cost per equivalent unit by assuming that more of the higher-cost units are completed and
transferred out, while some of the lower-cost units in beginning work in process are placed in
ending work in process. So, in this case, the weighted-average method results in a higher cost of
units completed and transferred out and a lower ending work-in-process inventory relative to
FIFO.

Transferred-in costs are 100% complete, and direct materials are 0% complete in both
beginning and ending work-in-process inventory. The reason is that transferred-in costs are
always 100% complete as soon as they are transferred in from the Assembly Department to the
Testing Department. Direct materials in beginning or ending work in process for the Testing
Department are 0% complete because direct materials are added only when the testing process is
90% complete and the units in beginning and ending work in process are only 70% and 60%
complete, respectively.

The equivalent units of work done in April 2007 in the Forming Department for direct materials
and conversion costs are shown in Solution Exhibit 17-37A.
Solution Exhibit 17-37B calculates the cost per equivalent unit of work done in April 2007
in the Forming Department for direct materials and conversion costs, summarizes the total
Forming Department costs for April 2007, and assigns these costs to units completed (and
transferred out) and to units in ending work in process under the FIFO method.
The equivalent units of work done in beginning inventory is: direct materials, 300  100%
= 300; and conversion costs 300  40% = 120. The cost per equivalent unit of beginning
inventory and of work done in the current period are:

$122,125
The FIFO ending inventory is higher than the weighted-average ending inventory by $434.
This is because FIFO assumes that all the lower-cost prior-period units in work in process are the
first to be completed and transferred out while ending work in process consists of only the
higher-cost current-period units. The weighted-average method, however, smoothes out cost per
equivalent unit by assuming that more of the higher-cost units are completed and transferred out,
while some of the lower-cost units in beginning work in process are placed in ending work in
process. Hence, in this case, the weighted-average method results in a higher cost of units
completed and transferred out and a lower ending work-in-process inventory relative to FIFO.

Difference
–$5,908
+$ 878
The FIFO ending inventory is higher than the weighted-average ending inventory by $878.
This is because FIFO assumes that all the lower-cost prior-period units in work in process
(resulting from the lower transferred-in costs in beginning inventory) are the first to be
completed and transferred out while ending work in process consists of only the higher-cost
current-period units. The weighted-average method, however, smoothes out cost per equivalent
unit by assuming that more of the higher-cost units are completed and transferred out, while
some of the lower-cost units in beginning work in process are placed in ending work in process.
Hence, in this case, the weighted-average method results in a higher cost of units completed and
transferred out and a lower ending work-in-process inventory relative to FIFO. Note that the
difference in cost of units completed and transferred out (–$5,908) does not fully offset the
difference in ending work-in-process inventory (+$878). This is because the FIFO and weightedaverage methods result in different values for transferred-in costs with respect to both beginning
inventory and costs transferred in during the period.

17-43 (20 min.) Equivalent-unit computations, benchmarking, ethics.
1.
The reported monthly cost per equivalent unit of either direct materials or conversion
costs is lower when the plant manager overestimates the percentage of completion of ending
work in process; the overestimate increases the denominator and, thus, decreases the cost per
equivalent unit. The plant manager has two motivations to report lower cost per equivalent unit
numbers: (1) to get a bonus and (2) to be recognized in the company newsletter.
2.
While the plant controller has responsibility for preparing the accounting reports for the
plant, in most cases, the plant controller reports directly to the plant manager. If this reporting
relationship exists, Major may create a conflict of interest situation for the plant controller. Only
if the plant controller reports directly to the corporate controller, and indirectly to the plant
manager, should Major show the letters to the plant controller without simultaneously showing
them to the plant manager.
3.
The plant controller’s ethical responsibilities to Major and to Leisure Suits are the same.
These include:
 Competence: The plant controller is expected to have the competence to make
equivalent unit computations. This competence does not always extend to making
estimates of the percentage of completion of a product. In Leisure Suits’s case,
however, the products are probably easy to understand and observe. Hence, a plant
controller could obtain reasonably reliable evidence on percentage of completion at a
plant.
 Objectivity: The plant controller should not allow the possibility of the plant being
written about favorably in the company newsletter to influence the way equivalent
unit costs are computed. The plant controller has a responsibility to communicate
information fairly and objectively.
4.
Major could seek evidence on possible manipulations as follows:
a. Have plant controllers report detailed breakdowns on the stages of production and
then conduct end-of-month audits to verify the actual stages completed for ending
work in process.
b. Examine trends in ending work in process. Divisions that report low amounts of
ending work in process relative to total production are not likely to be able to greatly
affect equivalent unit cost amounts by manipulating percentage of completion
estimates. Divisions that show sizable quantities of total production in ending work in
process are more likely to be able to manipulate equivalent cost computations by
manipulating percentage of completion estimates.

added only when the process is 80% complete and the beginning WIP is only 60% complete. We
had calculated the total equivalent units of work done in the current period in requirement 1:
transferred-in costs, 9,000; direct materials, 19,000; and conversion costs, 11,000. The missing

NANTUCKET NECTARS: Process Costing
1.
In a process-costing system, the unit cost of a product or service is obtained by assigning
total costs to many identical or similar units, in this case, single-serve juice beverage bottles.
2.
Direct Material Item
Raw ingredients for juices
(water, cane sugar, fruit juice concentrates, etc.)
Bottles and caps
Labels, cardboard trays, shrink-wrap
Stage in Production Process
Beginning
Middle
End
3.
Conversion costs include labor associated with the production line, depreciation on
production equipment, plant utilities, plant maintenance costs, and plant property taxes.
4.
In the process described for the manufacture of Nantucket Nectars juices, there is no
partially completed inventory, as the product is mixed and bottled within a few hours each
production day. Accordingly, the calculation of equivalent units in this case makes little sense.
As there is no partially completed ending inventory, there will be no difference between the cost
of the units transferred out under the weighted average or FIFO methods.
