started; all units completed in the same period or in the ending inventory of that
period are treated the same. In computing the equivalent units, this method looks

entries are essentially the same as in job costing. However, instead of tracing
departments.

conversion costs directly to finished goods inventory, by assuming there is little or

model in which certain products require significantly more processing costs in
certain activities. Activity-based costing is used together with process costing to

6-27 Process Costing in Process Industries (10 min)
There are a number of possible answers here. Some examples are given
in the chapter, as well as exercises 4-29 and 4-30 from chapter 4. The
exercise is intended for class discussion. The goals is to have the
students able to identify process-oriented companies in industries such as
chemicals, food processing, beverages, etc. The instructor may choose
to follow up this short question with a more substantive one such as 6-29
which gets into the details of one type of process industry, sugar
manufacturing.

6-28 Equivalent Units; Weighted-Average Method (15 min)
1. Calculate the number of tons completed and transferred out during the
2. Calculate the number of equivalent units for both materials and
conversion for the month of May, assuming that the company uses the
weighted-average method.
3. How would your answer in part 2 change if the percentage of completion
in ending inventory were as follows: materials 30%, conversion 40%?
4. Process costing is a good fit for the fish processing industry because
there is single or a small number of products that are processed through a
series of well-defined processing steps: moving, cleaning, preparation for
shipment, etc.

6-29 Process Costing in Sugar Manufacturing (20 min)
1. There are very likely to be transferred in costs in sugar
manufacturing, as there are a number of processes, each of which
could be a separate manufacturing department with its own process
cost report. There are seven steps in the manufacturing process so
there are possibly as many as seven departments, each with its own
cost report. The reason for multiple cost reports is to monitor the flow
of costs throughout the manufacturing process start to finish, and to
be able to control costs in each department. The individual cost
reports provide a means for tracking cost management performance
of each department over time. For example, it would be possible to
next chapter, Chapter 7.
2. As noted in the problem, the raw material for sugar production (sugar
cane) goes through periods of very volatile changes in price. This
means the cost of sugar can fluctuate greatly, and the production
costs may be given greater attention, especially in periods when
prices are low and sugar manufacturers compete on cost leadership
since sugar is a commodity. One could argue that FIFO provides a
better means to analyze costs since it separates costs from period to
period. Alternatively, one could argue that an advantage of the
weighted average method is that it would tend to smooth the changes
