Weighted-average method, equivalent units.

Consider the following data for the assembly division of Fenton Watches, Inc.:
The assembly division uses the weighted-average method of process costing.

	Physical Units (Watches)	Direct Materials	Conversion Costs
Beginning work in process (May 1) a	80	$493,360	$91,040
Started in May 2012	500
Completed during May 2012	460
Ending work in process (May 31)b	120
Total costs added during May 2012		$3,220,000	$1,392,000
a. Degree of completion: direct materials, 90%; conversion costs, 40%.
b. Degree of completion: direct materials, 60%; conversion costs, 30%.

Required:
1. Compute equivalent units for direct materials and conversion costs. Show physical units in the first column of your schedule.

2. Summarize total costs to account for, calculate cost per equivalent unit for direct materials and conversion costs, and assign total costs to units completed (and transferred out) and to units in ending work in process.

3. Suppose the assembly division at Fenton Watches, Inc., uses the FIFO method of process costing instead of the weighted-average method. Compute equivalent units for direct materials and conversion costs. Show physical units in the first column of your schedule.
