QUESTION 3 : PROCESS COSTING

A factory operates two processes. Output from Process 1 is transferred as input to Process 2. Output from Process 2 is the finished product. Data for the two processes in June 2018 are as follows:

Process 1

Opening work in process

Nil

Units introduced into the process

14,000u

Units completed and transferred to Process 2

10,000u

Closing work-in-progress units

4,000u

Material cost added during the period

$70,000

Conversion cost added during the period

$48,000

Materials are input into Process 1 at the start of the process and conversion costs are incurred at a constant rate throughout processing. The closing work-in-progress in Process 1 at the end of June 18 is estimated to be 50% complete for the conversion work.

Process 2

Opening work-in-process

Nil

Units transferred into the process from Process 1

10,000u

Closing work-in-progress units

1,000u

Units completed and transferred to finished goods inventory

9,000u

Costs for the period:

Cost of production transferred from Process 1

$90,000

Conversion cost added during the period

$57,000

Added materials during Process 2

$36,000

The materials from Process 1 are introduced at the start of processing in Process 2, but the added materials are introduced at the end of the process. Conversion costs are incurred at a constant rate throughout processing. The closing work-in-progress in Process 2 at the end of June 2018 is estimated to be 50% complete.

REQUIRED:

a)Using FIFO method of valuation, calculate the following:-

i)Unit cost of production for each material and conversion costs, for Process 1 and Process 2 separately.

ii)Calculate the total costs for each material and conversion costs, for Process 1 and Process 2 separately.

b)Prepare the Process 1 and Process 2 accounts for June 2018.
