All rights reserved 6 Key Concepts Conversion costs –Costs incurred to convert raw materials into a finished product –Direct labor plus manufacturing overhead Equivalent unit of production –Amount of work done during a period in terms of fully complete units of output

All rights reserved 16 Objective 4 Use the weighted-average method to assign costs to units completed and to units in ending work in process inventory in a second department When working with a second department, we have to consider the costs transferred in from the previous department as well as costs added in the second department

The weighted average method combines the work in process at the beginning with the work done during the period to get the average cost of the units
