Part 2: Brunners Corp.

**Answer to comment: Direct Labor Hours are found in Table 2. They are listed in the third and four box in table**

Jeri Cooper, the sales manager of Brunners Corporation, is getting worried. Her last three bids were rejected in favor of a lower bid from a new competitor to the market. Now, she is putting together a bid for a potential new customer, and she wants to make sure the price is competitive, but still profitable. As the managerial accountant at Brunners, your job is to help Jeri prepare bids by providing the most accurate cost estimates.

Brunners is a plastic injection custom molding company, which advertises its highly automated process as keeping costs low. Currently, Brunners uses a traditional (plantwide) costing system, with overhead costs allocated based on total direct labor hours. Brunners expects to use a total of 95,000 direct labor hours this year. Suspecting that their traditional costing system is partially to blame for their recent problems, Brunners has begun the process of implementing ABC. However, before this new company entered the market, Brunners had little need to review their processes. Jeri has very little understanding of cost accounting and has asked if her recent unsuccessful bids were due to an inaccurate costing system, or if there are process inefficiencies that have driven up costs.

In the ABC implementation process, Brunners Corporation has identified four activities. The production activity is a highly automated process, where a few workers oversee several machines as they produce parts. This is a large cost pool, as it includes the depreciation on the building and all the plastic injection molding machines (i.e., millions of dollars of property, plant, and equipment), and the wages of these production employees is directly traced to the job. In the materials activity, workers with specialized machine training prepare each machine for a new process or color (setups) by cleaning and changing the molds in the machines, and then refilling the machines with plastic pellets (refills) as needed. Wages of these workers is considered indirect labor. In the correction process, workers trim extra plastic from the parts. This extra plastic normally snaps off cleanly as the parts come out of the mold, but often needs to be trimmed as the molds get worn or if the mold is not correctly installed in the machine. Wages of these workers is also directly traced to the job. The trimming process is also where parts that are defective are thrown out, so this activity also includes the cost of wasted materials. Finally, in the inspection activity, inspectors randomly select and inspect parts to ensure compliance with the customers specifications. Inspectors wages are considered indirect labor.

Having determined four activities used at Brunners, the ABC implementation team has separated the plants total overhead costs into the activity cost pools (see Table 1). The next step in the ABC implementation process it to identify cost drivers for each activity. So far, they have identified cost drivers for each of the activities (see Table 1). This is still a work in progress, though, and they are still making adjustments.

The proposed job is somewhat different, requiring pieces in a variety of colors (see Table 2 for details on the proposed job). Historically, customer jobs have required only one or two setups. While Brunners has not needed to support these types of requests in the past, several recent bids (all rejected) have had similar needs. The plant manager believes that these types of jobs will increase in the future. Proving that they can support these requests may result in new business in the future.

Youve realized that you could provide value to Brunners in a several different ways. First, providing cost estimates from both the traditional process and the proposed ABC method could shed some light on the accuracy of the cost estimation process. Second, you can use activity-based management to identify improvements that could be made to the production process (if any). Finally, with your knowledge of this job (and the market looking forward), you could provide some valuable input to the ABC implementation team.

Required:

Write a 1-2 page memo, as the accountant of Brunners Corp, addressed to Jeri Cooper describing your analysis and the outcomes. Make sure you respond to the following items:

1. Provide a total cost estimate using the current traditional costing system.

2. Provide a total cost estimate using the activity based costing system proposed by the ABC implementation team.

3. Explain to Jeri which cost estimate should be used to develop her bid, and why.

4. Use activity based management to respond to Jeris question about process inefficiencies driving up costs.

5. Evaluate the ABC system as it currently stands. Explain what specific change(s) you recommend the ABC implementation team make, and how that could affect your cost estimates.
