The following information is available from the Oils Division of Glasgow Corporation for December. Conversion costs for this division were 80 percent complete as to beginning work-in-process inventory and 60 percent complete as to ending work-in-process inventory. Information about conversion costs follows.
| Units | Conversion Costs | |||||
| WIP at December 1 (80% complete) | 112,000 | $ | 443,520 | |||
| Units started and costs incurred during December | 552,000 | 2,628,480 | ||||
| Units completed and transferred to next department during December | 412,000 | ? | ||||
The Oils Division uses FIFO.
Required:
a-1. Compute the equivalent units for conversion costs.
a-2. Compute the cost per equivalent unit for conversion costs.
a-3. What was the conversion cost of work-in-process inventory in the Oils Division at December 31?
b. What were the conversion costs per equivalent unit produced last period and this period, respectively?
a-1) WIP at December31 = Opening WIP + Units Started during the period - Units Completed & transfered
= 112000 + 552000 - 412000
= 252000 Units (60% Completed)
Equivalent Units = Actual Number Units in the process * Percentage of work Completed

a-2) Cost per Equivalent Units = Cost Incurred during December / Equivalent Units
= $ 2,628,480 / 540800 Units
= $ 4.86 approx.
a-3) Conversion cost of work-in-process inventory in the Oils Division at December 31
= Closing WIP Equivalent Units * Cost per Equivalent Units
= 151200 Units * $ 4.86
= $ 734,886
Cost of Units Completed and Tranferred to next Department = 412000 Units * Cost per Equivalent Unit @ $4.86
= $ 2,002,320
b) Conversion costs per equivalent unit produced last period
| Particulars | Units | % Completion | Equivalent Units(EU) | Cost ($) | Cost per EU ($) | 
| Opening WIP | 112000 | 80% | 89600 | 4,43,520 | 4.95 | 
Conversion costs per equivalent unit produced this period(December)
= Cost Incurred during December / Equivalent Units
= $ 2,628,480 / 540800 Units
= $ 4.86 approx.
