Problem 3: ABC Electronics Company has two departments to manufacture computers,
Assembly and testing departments. First component parts are assembled in assembly department
and then transferred out to testing department. Direct materials are added some where in between
the assembly process but conversion costs are added evenly through out the assembly process.
The company uses process costing system. The following data are for the month of January for
assembly department.
Physical units
Beginning WIP

Started in the month
2,500
Completed units
2,300
Cost added during the month
Direct material
$2,484,000
16,100,000
Conversion cost
$464,000
6,960,000
Additional information
There are 200 spoiled units 50% of which is abnormal
Degree of completion –Beginning WIP
 Direct material (90% complete)
 Conversion cost (40% complete)
 Degree of completion –Ending WIP
 Direct material (60% complete)
 Conversion cost (30% complete)
Requirements: Under FIFO method
a) Summarize the flow of physical units
b) Compute equivalent unit in terms of each cost
