Disposition Cost
In the lamination department, varnish is added when the goods are 60% complete as to overhead. The units that are spoiled during processing are found upon inspection at the end of production. Spoilage is considered discrete.
Production Data For March
Beg.Inv.(80% complete as to labor,
70% complete as to overhead): 1,000 units
Transferred in during month 7,450 units
End. Inv.(40% complete as to labor
20% complete as to Overhead) 1,500 units
Normal Spoilage(found in final inspec) 100 units
Abnormal Spoilage(Found @ 30%completion
of direct labor & 15% of conversion) 200 units

Solution Preview
Number of complete units made and transferred = 1,000 + 7,450 - 1,500 - 100 - 200 = 6,650.
<br>
<br>The number of units with prior department costs = 1,000 + 7,450 = 8,450.
<br>The total prior department costs = $7,510 + $68,540 = $76,050.
<br>The prior department cost per unit = $76,050 / 8,450 = $9.00.
<br>
<br>Equivalent full labor units = 1,000 + 7,450 - (0.6 * 1,500) - (0.7 * 200) = 7,410.
<br>This is calculated as follows: there are 1,000 + 7,450 = 8,450 ...
Solution Summary
This solution determines the proper cost of disposition (spoilage) using a weighted average method.
