Fabian Company uses the weighted-average method in its process costing system. The Assembly Department started the month with 9,000 units in its beginning work in process inventory that were 70% complete with respect to conversion costs. An additional 90,000 units were transferred in from the prior department during the month to begin processing in the Assembly Department. During the month 87,000 units were completed in the Assembly Department and transferred to the next processing department. There were 12,000 units in the ending work in process inventory of the Assembly Department that were 20% complete with respect to conversion costs.
What were the equivalent units of production for conversion costs in the Assembly
Department for the month?
A)89,400.
B)83,100.
C)93,000.
D)87,100.

The equivalent units of production for conversion costs are calculated by adding the completed units to the equivalent units in the ending work in process inventory. The completed units are 87,000. For the beginning inventory, since it's already 70% complete, we only consider the remaining 30% for these 9,000 units, which is 2,700 equivalent units. For the ending inventory of 12,000 units at 20% completion, this gives 2,400 equivalent units. Therefore, the total equivalent units for conversion costs are 87,000 (completed) + 2,700 (from beginning inventory) + 2,400 (from ending inventory) = 92,100. However, since this option is not available and there seems to be a mistake in my calculation, the correct approach should be considered as follows: For the units completed, 87,000 units are fully processed, so they count as 87,000 equivalent units. For the ending work in process, 12,000 units are 20% complete, contributing 2,400 equivalent units (12,000 * 20%). The beginning inventory's contribution was incorrectly considered in my initial explanation; instead, we should focus on the work done during the current period. Thus, the correct calculation directly considers the work done on all units during the period without needing to adjust for the beginning inventory's state of completion. Therefore, the correct answer must be calculated based on the information provided and the principles of process costing, focusing on the units completed and the ending work in process. Given the misunderstanding in the initial explanation, the correct calculation aligns with the principles of the weighted-average method, considering all work done during the period.
