What will be an ideal response

Miller, Inc.
Production Cost Report—Assembling Department—
FIFO Method—Whole Units
Month Ended December 31
Whole Units
Units to account for:
Beginning WIP 10,000
Started in production 30,000
Total units to account for 40,000
Units accounted for:
Beginning WIP 10,000
Started and completed 10,000
Transferred to Packaging Department 20,000
Ending WIP 20,000
Total units accounted for 40,000

Notes:
Ending Work-in-Process Inventory = Beginning Work-in-Process Inventory + Amount transferred in - Amount transferred out
Ending Work-in-Process Inventory = 10,000 + 30,000 - 20,000 = 20,000 units

Accounted for = Beginning balance + Started and completed + In process
Accounted for = 10,000 units + 10,000 + 20,000 = 40,000 units

Started and completed = Completed and transferred - Beginning balance
Started and completed = 20,000 - 10,000 = 10,000 units
