CHAPTER 17 (FIN MAN); CHAPTER 3 (MAN)
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.
2. Because 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
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.

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. Because
conversion costs are incurred only when the cereal is filled into boxes, all 800
boxes of the March 1 inventory in process will have conversion costs incurred in
March.

b. Yes. The production costs per unit decreased during the current period. The
cost per unit of the units started and completed during the period is $9.80
($6.80 + $3.00). Because the cost per unit of the beginning work in process is
$9.84 [see a. 4 above], the production costs during the current period must
have decreased.

The errors are listed below.
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
3. The correct equivalent units for conversion costs should be 53,400, instead of 53,480,
as computed below.
