Often, only two cost classifications, direct materials and conversion costs, are necessary. Direct materials are frequently added at one point in time, often the start or the end of the process, and all conversion costs are added at about the same time, but in a pattern different from direct materials costs. 17-3 Equivalent units is a derived amount of output units that takes the quantity of each input (factor of production) in units completed or in incomplete units in work in process, and converts the quantity of input into the amount of completed output units that could be made with that quantity of input. Each equivalent unit is comprised of the physical quantities of direct materials or conversion costs inputs necessary to produce output of one fully completed unit. Equivalent unit measures are necessary since all physical units are not completed to the same extent at the same time. 17-7 The weighted-average process-costing method calculates the equivalent-unit cost of all the work done to date (regardless of the accounting period in which it was done), assigns this cost to equivalent units completed and transferred out of the process, and to equivalent units in ending work-in-process inventory. 17-8 FIFO computations are distinctive because they assign the cost of the previous accounting period’s equivalent units in beginning work-in-process inventory to the first units completed and transferred out of the process and assigns the cost of equivalent units worked on during the current period first to complete beginning inventory, next to start and complete new units, and finally to units in ending work-in-process inventory. In contrast, the weighted-average method costs units completed and transferred out and in ending work in process at the same average cost. 17-11 The journal entries in process costing are basically similar to those made in job-costing systems. The main difference is that, in process costing, there is often more than one work-in- process account––one for each process. 17-13 There are two reasons why the accountant should distinguish between transferred-in costs and additional direct materials costs for a particular department: (a) All direct materials may not be added at the beginning of the department process. (b) The control methods and responsibilities may be different for transferred-in items and materials added in the department. 17-14 No. Transferred-in costs or previous department costs are costs incurred in a previous department that have been charged to a subsequent department. These costs may be costs incurred in that previous department during this accounting period or a preceding accounting period....
