CHAPTER 20
PROCESS COST SYSTEMS
DISCUSSION QUESTIONS
1.
a.
An assembly-type industry using mass production methods, such as TV assembly, would
use the process cost system because the products are somewhat standard and lose their
identities as individual items. In such industries, it is neither practical nor necessary to
identify output by jobs.
b.
A job order cost system would be used by a building contractor to accumulate the costs
for each individual building because the costs can be identified with each job without
great difficulty.
c.
A job order cost system is best suited for an automobile repair shop because costs can
be reasonably identified with each job.
d.
A process cost system would be best suited for a paper manufacturer because the
processes are continuous and the products are homogeneous.
e.
A job order cost system is best suited for a custom jewelry manufacturer because most of
the production consists of job orders, and costs can be reasonably identified with each job.
2.
Since all goods produced in a process cost system are identical units, it is not necessary to
classify production costs into job orders.
3.
In a process cost system, the direct labor and factory overhead applied are debited to the
work in process accounts of the individual production departments in which they occur. The
reason is that all products produced by the department are similar. Thus, there is no need to
charge these costs to individual jobs. For the process manufacturer, the direct materials and
the conversion costs are charged to the department and divided by the completed production
of the department to determine a cost per unit.
4.
The cost per equivalent unit is frequently determined separately for direct materials and
conversion costs because these two costs are frequently added at different rates in the
production process. For example, materials may be incurred entirely at the beginning of the
process, while conversion costs are typically incurred evenly throughout the process.
5.
The cost per equivalent unit is used to allocate direct materials and conversion costs between
completed and partially completed units.
6.
The transferred-in cost from Blending to Filling includes the materials costs, direct labor, and
applied factory overhead incurred to complete units in Blending.
7.
The most important purpose of the cost of production report is to assist in the control of
costs. This is accomplished by holding each department head responsible for the costs
incurred in the department.
8.
Cost of production reports can provide detailed data about the process. The reports can
provide information on the department by individual cost elements. This can enable
management to investigate problems and opportunities.

9.
Yield is a measure of the materials usage efficiency of a process manufacturer. It is
determined by dividing the output volume of product by the input volume of product.
For example, if 950 tons of aluminum were rolled from 1,000 tons of ingot, then the yield
would be said to be 95%. Five percent of the ingot was scrapped during the rolling process.
10.
Just-in-time processing emphasizes combining process functions into manufacturing cells,
involving employees in process improvement efforts, eliminating wasteful activities, and
reducing the amount of work in process inventory required to fulfill production targets.

Total……………………………………………
Supporting explanation:
The whole unit inventory in process on March 1 includes both the cereal in the
hopper and the boxes in the carousel, and thus includes no equivalent units for
the material during the current period. The reason is because the costs for the
cereal and boxes were introduced to the Packing Department in February. Since
conversion costs are incurred only when the cereal is filled into boxes, all 600
boxes of the March 1 inventory in process will have conversion costs incurred
in March.
The product started and completed in March includes 50,200 boxes (50,800 boxes
completed less the 600 in the carousel on March 1). These boxes represent 75,300
pounds of cereal [50,200 × (24 oz. ÷ 16 oz.)], since there are 16 ounces to a pound.
The inventory in process on March 31 includes the remaining pounds of cereal in
the hopper and boxes in the carousel that are properly included in the equivalent
unit computation for March (since the costs were incurred in the department in
March). No conversion costs have been applied to these boxes, since they
remain unfilled.
Note to Instructors: An actual cereal-filling line begins with the empty box
carousel. The box carousel holds flattened boxes that are fed into a high-speed line
that opens the box up and places it on a conveyor. The conveyor brings the opened
box under a filler head. The cereal pours from the hopper through the filler head
into the open box (actually into the inner sealer bag). The box then moves down the
line to be boxed into a large shipping carton, which is then moved to the
warehouse.

b.
Yes. The production costs per unit increased during the current period. The
cost per unit of the units started and completed during the period is $33 ($21
+ $12). Since the cost per unit of the beginning work in process is
$32.74 [see part (4) above], the production costs during the current period
must have increased.

1.
In computing the equivalent units for conversion costs applicable to the June 1
inventory, the 6,400 units are multiplied by 3/5 rather than 2/5, which is the
portion of the work completed in June. Therefore, the equivalent units should
be 2,560 (6,400 × 2/5) instead of 3,840.
2.
In computing the equivalent units for conversion costs for units started and
completed in June, the June 1 inventory of 6,400 units, rather than the June 30
inventory of 5,200 units, was subtracted from 55,000 units started in the
department during June. Therefore, the equivalent units started and completed
should be 49,800 instead of 48,600.
3.
The correct equivalent units for conversion costs should be 53,400, determined
as follows:
To process units in inventory on June 1:
