Weighted Average Method, FIFO Method, Physical Flow, Equivalent Units

Middelton Company manufactures a product that passes through two processes: Fabrication and Assembly. The following information was obtained for the Fabrication Department for October:

1. All materials are added at the beginning of the process.
2. Beginning work in process had 81,600 units, 40 percent complete with respect to conversion costs.
3. Ending work in process had 12,400 units, 20 percent complete with respect to conversion costs.
4. Started in process, 105,000 units.

Required:

1. Prepare a physical flow schedule.

Feedback

1. The physical flow schedule traces the units in process regardless of their stage of completion and provides the information needed for preparing the equivalent units schedule.

2. Compute equivalent units using the weighted average method.

3. Compute equivalent units using the FIFO method.

Feedback

2. To calculate equivalent units, weighted average counts prior-period output in BWIP as belonging to the current period. So all completed units are treated as output of the current period.

3. FIFO treats the work (equivalent output) in BWIP as belonging to the prior period and only counts the work (equivalent output for each input) done this period as part of this period's output.

4. Suppose that the cost of direct materials in beginning work in process is $566,600 and that the direct materials cost incurred for October is $714,500. With these changes, answer the following:

a. What is the unit materials cost for the units in BWIP? Round your answers to the nearest cent. $fill in the blank 34f69e020019036_1

b. What is the unit materials cost for units produced in October? Round your answers to the nearest cent. $fill in the blank 34f69e020019036_2

Which method should be used to answer this question?

Weighted AverageFIFO

Explain why the unit materials cost is not the same for weighted average and FIFO.

Of the two unit calculations,

Weighted AverageFIFO

uses only October costs and October output, so it

shouldshould not

be used to calculate the unit materials cost for October. When those costs are changing from one period to the next, then the unit costs for FIFO and WA

willwill not

differ.

As part of your explanation, show that the weighted average unit cost for materials is the blend of the September unit materials cost and the October unit materials cost.

Because the weights are the

of total equivalent units for each unit cost.

c. Which data analytic types (descriptive, diagnostic, predictive, or prescriptive) apply for 4a and 4b? Note: More than one data analytic type might apply. (See Exhibit 2.5 and Exhibit 2.6 for a review of data analytic metrics.)
