ProdCo adds all material at the beginning of production and incurs conversion costs evenly throughout production. They completed 70,000 units during the year and 12,000 units were still in process at the end of the year which were 20% complete with respect to conversion. Using the weighted average method for process costing, equivalent units for the year were as follows: materials 72400 & conversion 72400, materials 70000 & conversion 70000, materials 82000 & conversion 72400, or materials 70000 & conversion 72400
