Chapter 3Process Costing
QUESTIONS
1. Job-order costing systems and process costing systems are the two primary accounting
systems used to record production costs.
2. Equivalent units is the quantity of partially completed units expressed in terms of wholeunits. The number is used in calculating the average unit costs under process costing.
3. Direct labor and overhead, together, are called conversion costs.
4. The costs associated with units received from a preceding department within the companyfor further processing are called transferred-in costs.
5. Material may enter at the start of a production process while labor and overhead are
incurred throughout the process.
6. Cost per equivalent unit = (Cost in beginning work in process + Cost incurred in currentperiod) ÷ (Units completed + Equivalent units in ending work in process).
7. Cost to account for = (Cost in beginning work in process + Cost incurred in current period).
8. Reconciliation helps to ensure that mistakes are not made in calculations and units are not“lost.”
9. Transferred-in costs are the costs associated with units received from a preceding
department within the company received for further processing. Therefore, they occur in allproduction departments except the first.
10. The four steps involved in preparing a production cost report are as follows:a. Account for the number of physical unitsb. Calculate the cost per equivalent unit for material, labor, and overheadc. Assign costs to items completed and items in ending work in processd. Account for the amount of product cost

EXERCISES
E1. In the production of chips, much of manufacturing overhead is a fixed cost.
This cost is assigned to completed items and work in process. By starting alarge number of items at year end, and given the simplifying assumption that
items in process are 50% complete, a significant proportion of the fixed
manufacturing overhead will end up in work in process, which reduces thecost of finished items and ultimately the cost of goods sold. The result is that
profit will be artificially inflated.
This approach to increasing profit may mislead investors and other
stakeholders and cause them to make bad decisions. Thus, the behavior is notethical.
E2. Cost per equivalent unit is calculated for material, labor and overhead. For
each of these items, we sum the cost in beginning work in process and the cost
incurred during the period. This becomes the numerator of the calculation.Then, we determine the number of units completed and the equivalent units in
ending work in process. This becomes the denominator of the calculation.
It is important to note that the equivalent units in ending work in process may
be different for material, labor, and overhead. This is because material, labor,and overhead enter the production process at different times.
E3. a. There are 11 steps:
Brew HouseStep 1, malted barley—barley is mixed with water, dried and cured.
Step 2, mill—the grain is cracked by steel grinders.
Step 3, mash tun—malt is mixed with warm water in the mash tun.Step 4, lauter tun—the mash is pumped into the lauter tun where it is sprayed
with hot water to help extract sugar from the malt.
Chapter 3 Process Costing 3-3
Step 5, brew kettle–the base of beer, or “wort,” is pumped into the brew kettlewhere it is boiled, concentrated and clarified.
Step 6, heat exchanger—the wort is cooled before it is moved to afermentation cellar where it will become beer. In order to speed the cooling
process, it is passed through a heat exchanger.
In the cellarStep 7, fermenter—here, specially cultured yeast, Saccharomyces cerevisiae,is added to induce fermentation.
Step 8, filtration—after the beer has been cold cellared in the fermenter, it is
passed through a filter.
PackagingStep 9, bottling—the bottling line is made up of several components. At the
heart of the system is a counter-pressured filler which is capable of filling 400
bottles a minute.Step 10, kegging—Redhook uses ‘Snakey’ kegs, which have the advantage of
being much easier to sterilize and fill than older types such as ‘Golden Gates.’
Step 11, shipping—ales are shipped out to stores and pubs across the UnitedStates in refrigerated trucks to keep them fresh.
b. For each type of beer that Red Hook produces, a large number of identical
units are produced in a continuous process. Thus, the company is likely to
use process costing.
c. Barley is added at the start. In step 7, yeast is added.
d. The process is capital intensive. Large pieces of equipment are maintained
by only one or two workers. For example, the automated bottling line fills400 bottles a minute.

Units to account for 44,000 cans
Units completed 40,000Units in ending work in process ?
Total units accounted for 44,000 cans
Units in ending work in process = 44,000 - 40,000 = 4,000 cans.
E5. Units in beginning work in process 10,000
Units started in August ? Units to account for 52,000 gallons
Units completed 40,000

Units started in August = 52,000 - 10,000 = 42,000 gallons.

Cost per equivalent unit = $620,000 ÷ 11,000 pounds = $56.36 per pound
E7. Let X = the cost in beginning work in process
Material:($140,000 + X) ÷ (30,000 + 10,000) = $5
X = $60,000
Labor:($60,000 + X) ÷ (30,000 + 2,000) = $2
X = $4,000
Overhead:($87,000 + X) ÷ (30,000 + 2,000) = $3
X = $9,000

E9. a. Cost per equivalent unit for material is $6.10. Material cost in itemscompleted is $244,000. Therefore, the number of completed units is 40,000(i.e., $244,000 ÷ $6.10).
Units in beginning work in process 1,000Units started in July 43,000Units to account for 44,000 cans
Units completed 40,000Units in ending work in process ? Total units accounted for 44,000
This implies that 4,000 units are in ending work in process.
b. Cost of ending work in process is $5,800 as follows:
Material (.2 × 4,000 units × $6.10) $4,880Labor and overhead (.1 × 4,000 units × $2.30) 920
