• The company was founded to transport kerosene from eastern refineries to Utah by railroad tank and sell it
in bulk, making it affordable for the pioneers.
• Today, the Conoco brand is owned by ConocoPhillips and Conoco Quality PROclean Gasolines are sold at
more than 3,100 retail fuel sites in the United States.
• The company has 32,500 employees and assets of $173 billion.
• Top competitors are BP, Exxon, Mobil, and Royal Dutch/Shell.
• This system is usually appropriate in situations in which there are continuous operations on standard types
of products.
1. Products are not made in batches or special orders.
3. Beginning work in process inventory and costs added during the current period.
4. Multiply units in ending work in process inventory by stage of completion for each cost element to
6. Yes. All cost data is posted to the departmental Work in Process accounts.
8. If products are not the same, the average cost calculation will be meaningless.
10. Each element of cost in beginning inventory is added to amount of that element incurred during month.
11. Number of units of product transferred out of department is multiplied by 100 percent to determine number

Discussion Questions
CHAPTER 28
PROCESS COST ACCOUNTING
Chapter Opener: Thinking Critically
Students’ responses will vary. As ConocoPhillips products move through different refineries, production costs are
most likely classified and tracked within each refining facility. For example, labor, materials, and overhead costs
for gallons of oil in production process for the Louisiana facility might be recorded separately from accounting
entries recorded for Venezuela operations.

EXERCISE 28.1
Equivalent units of production for prior department costs
EXERCISE 28.2
Equivalent units of production for materials:
EXERCISE 28.3
Equivalent units of production for labor and overhead
EXERCISE 28.4
1. Cost per equivalent unit for materials:
Transferred out to next department (6,000 × 100%) = 6,000
3. Cost of material in ending work in process = 2,000 × $3 = $6,000
EXERCISE 28.5
1. Equivalent units for materials
Materials
2. Cost per unit for material
Material costs ÷ Materials equivalent units = ($6,000 + $25,900) ÷ 3,000
=
$10.63
EXERCISE 28.6
1. Equivalent units for overhead
2. Cost per unit for overhead
Overhead costs equivalent units = ($3,000 + $15,000) ÷ 2,900 = $6.21
