Q3&4: Process Costing Example, with BI
Colors R Us, Inc. uses a process costing system for its sole processing
department. There were 6,200 units in beginning WIP inventory for
February and 57,500 units were started in February. The beginning WIP
units were 60% complete and the 5,000 units in ending WIP were 45%
complete. All materials are added at the start of processing. Compute the
EUP for DM and CC using both methods.
First, compute the # of units started & completed:

Q6: Accounting for Transferred-in Costs
• “Transferred-in costs” (TI) is merely another cost
category like DM or CC
• All processing departments except the first will
account for TI costs
• When preparing a process cost report for a
department with TI costs:
• Compute EUP for TI costs; all TI costs are incurred at the
start of processing
• Compute cost/EUP for TI costs
• Assign TI costs to EI units

Slide # 10
Q6: Process Costing Example, with TI Costs
Crusher Drugs manufactures a pain medication in a two-process cycle. In
Department 2, direct materials are added as follows: 20% are added at the
beginning of processing, and the rest at the 60% stage. There were 5,000
units in Dep’t 2’s beginning WIP inventory that were 40% complete, and
20,000 units were transferred in to Dep’t 2 in May. The Dep’t 2 ending WIP
inventory of 6,000 units was 55% complete. Compute the May EUP for all
cost categories for Department 2 using both methods.
First, compute the # of units started & completed:

Q5: What Alternative Methods are Used for Mass
Production?
• Adaptations to Traditional Process Costing
– Match equivalent units calculations more closely to actual
production processes
– Separate conversion costs into multiple pools
• Standard costs simplify the accounting
• Just-in-time production
• Hybrid costing, or operation costing

Slide # 16
Q7: Accounting for Spoilage in Process Costing
• Costs of normal spoilage are absorbed by
the good units transferred out.
• Costs of abnormal spoilage are charged to a
Loss from abnormal spoilage account.
• Costs attach to spoilage depending on when
spoilage is detected.

Q7: Process Costing & Spoilage Example
Hollidaze makes molded plastic party decorations. In June, there were 800
units in beginning WIP inventory that were 40% complete and the 500 units in
ending WIP were 30% complete. The company completed 3,000 units in
June, but 200 of these were defective and were discarded. The defective
units are located upon inspection before transfer to finished goods. It was
determined that 50 of these defective units should be considered normal
spoilage. The remaining spoilage occurred because of a rare machine
malfunction and should be considered abnormal spoilage. All direct materials
are added at the beginning of processing.
Compute the June EUP for DM and CC using both methods.
First, compute the # of units started & completed:

Q8: Process Costing Uses for Decision Making
• Used to determine valuation for inventory and cost of
goods sold at the end of each period
• Required for financial statements and income tax
returns
• Helps managers evaluate if the production processes
are operating as expected
• Compare actual results to budget, standards, or
prior periods
• Identify areas for process improvements
• Analyze benefits of quality improvements

Q8: Process Costing Limitations & Impacts on
Managers’ Decision Making
• Process cost information is generally not useful for
many short-term decisions because unavoidable
fixed costs are allocated to the products.
• Need to determine incremental or marginal costs
• Separating conversion costs into fixed and
variable pools would help
• Requires use of estimates:
• The point of the production process when DM
costs or CC are incurred.
• Stage of completion for all units in beginning and
ending WIP inventories
