Koric Inc. has two processing departments (machining and assembly) and uses the weighted average method of process costing. Conversion costs are added evenly during the production process. Direct materials are added at the beginning of the production process. In May, the following data were recorded for assembly department:

Assembly Department Physical Units Transferred-in Costs Direct Materials Conversion Costs

Work-in-process, beginning inventory, May 1* 60,000 $67,500 $90,000 $122,400 Transferred-in during May 170,000

Completed and transferred out 190,000

Work-in-process, ending inventory, May 31^ 40,000

Total costs added during May $438,500 $510,000 $648,000

* Degree of completion: transferred-in 100%; direct materials, 20%; conversion costs, 30%

^ Degree of completion: transferred-in 100%; direct materials, 25%; conversion costs, 60%

Required:

For May, summarize the total costs to account for, compute the cost per equivalent unit for transferred-in, direct materials, and conversion costs, and assign costs to units completed and transferred out and to units in ending work-in-process.
