The company for which you work recently implemented time-driven activity-based costing (TDABC) in conjunction with its enterprise resource planning (ERP) system. Management is pleased with the revised product and customer cost information that the TDABC system produces. It is now wondering how this system can be used for budgeting purposes. You have been asked to provide an example of using time-driven activity-based budgeting, given the following information:

1. There are two resources (departments): indirect labor and computer support.
2. There are two primary activities that these resources support: handling production runs and product-level support.
3. Indirect labor support is consumed as follows:

1. To handle production runs: 10 hours/run.
2. To support products: 520 hours/product.

4. Computer support is consumed as follows:

1. To handle production runs: 0.6 hours/run.
2. To support products: 52 hours/product.

5. Resource practical capacity levels:

1. Indirect labor: 20,400 hours per quarter.
2. Computer support: 520 hours per quarter.

6. Cost of supplying resources:

1. Indirect labor: $1,060,800 per quarter.
2. Computer support: $504,400 per quarter.

Required:

1. Calculate the budgeted resource cost per hour (at practical capacity) for each of the two resources, indirect labor support and computer support.

2. Determine the budgeted cost-driver rates for each of the two activities, handle production runs and support products.

3. Suppose that the total cost of resources supplied for the quarter just ended was exactly as budgeted (i.e., $1,565,200) but that only 18,400 indirect labor hours were used along with 470 computer hours. Calculate, for each resource, the cost of idle capacity.

4. After implementing a total quality management (TQM) program, the company was able to implement process-efficiency changes, the end result of which was a 20% reduction in the indirect labor time associated with the activity handling production runs. Recalculate the indirect labor cost component of the cost to handle a production run. Also, recalculate the cost of idle capacity for indirect labor assuming the original facts but with the 20% efficiency gain. Assume that in the original case facts, 16,200 of the 18,400 hours relate to the activity handling production runs (while the remaining 2,200 hours relate to the activity product-level support).

Two popular fiber ring technologies are FDDI (runs at 100 Mbps) and SONET (2.4 Gbps). Both are dual-ring technologies. Discover and report what that means.

Charlie’s Computer Correction Connection (C4) runs a chain of computer repair franchises. C4’s stock sells for $50 per share and has 1,000,000 shares outstanding. C4 just paid annual dividend of $2 per share and expects the growth rate to be 3% annually. C4 also has 10,000 bonds outstanding, maturing in 8 years with a face value of $1,000 each. The bonds have a 7% coupon rate (make semi-annual coupon payments) and currently sell for $1,000. The tax rate is 30%. What is C4’s weighted-average cost of capital?

Leila runs a lawn mowing/maintenance service for busy homeowners. She has six potential customers and each is has a different maximum price they are willing to pay per week. The customers and the maximum price each is willing to pay each week is as follows:

Customer      Price
Lorraine      $40
Gilda            15
Jane            30
John            25
Bill            20
Dan            35

Leila's costs depend on the number of customers she has. Her costs (she has no sunk costs) appear in the following table:

# of customers per week            Total Cost
      1                  $22
      2                  $44
      3                  $66
      4                  $88
      5                  $110
      6                  $132

In Situation 7.3, Leila's optimal number of customers is

1. . The file contains information about baseball players in a fictitious league. Here is a sample of the data:

Janet Littleton,6,7,14

Frank Edbrooke,17,9,31

Robert Hovery,25,1,18

Thomas Bingham,21,8,2

Stephen Bruce,7,9,23

For each player it shows:

1. Her name,
2. How many doubles she hit,
3. How many triples she hit,
4. How many home runs she hit [End of Line]

For example, Janet Littleton hit 6 doubles, 7 triples and 14 home runs. Frank Edbrooke hit 17 doubles, 9 triples and 31 home runs.

Your job is to determine:

1. How many players there are in the league, and
2. which players hit more triples than doubles and hit more triples than home runs. There are five players who meet these criteria:

1. This exercise is based on one in Hartman (2007). A pharmaceutical company needs to use a supercomputer to run simulation models as part of its research on cures for AIDS, cancer, and other diseases. The firm expects to perform thousands of simulation runs per year for the next 3 years. The firm can purchase a supercomputer for $2.5 million; the annual operating and maintenance costs are $200,000 per year, and the supercomputer can perform 15,000 runs per year. For every simulation run above 15,000 in a year, the operating costs rise $1,000 per year to cover the needed overtime. A second alternative is to outsource the simulation runs to an IT firm that offers supercomputing services on demand. They will charge the pharmaceutical company $400 per simulation run. Consider a 3-year time horizon, and assume that the number of runs per year is the same every year. The firm is not sure how many simulation runs they will need to perform each year. What is the range of total cost if the number of simulation runs varies from 10,000 to 20,000 runs per year? For what range of activity (number of simulation runs per year) is purchasing a supercomputer the lowest cost alternative?

2. Consider the supercomputer example from Exercise 1 above. The firm is not sure about some of the relevant costs. The following probability distributions reflect their beliefs about the uncertain costs: the annual operating and maintenance costs are uniformly distributed on the range [$150,000, $250,000]; the additional operating costs for simulation runs above 15,000 per year are uniformly distributed on the range [$500, $1500] (per run per year). Use the method of moments to estimate the mean and variance of the costs if the firm purchases the supercomputer and they perform 20,000 runs per year. Use Monte Carlo sampling to estimate the distribution of costs if the firm purchases the supercomputer and they perform 20,000 runs per year.

Data on manufacturing overhead at the plant follow. Machine depreciation $ 36,000 Setup labor 18,000 Material handling 14,400 Total $ 68,400 Required: a. Upriver currently applies overhead on the basis of machine hours. What is the predetermined overhead rate for the month? (Round your answer to 2 decimal places.) b. Upriver is thinking of adopting an ABC system. They have tentatively chosen the following cost drivers: machine hours for machine depreciation, production runs for setup labor, and direct material dollars for material handling. Compute the cost driver rates for the proposed system at Upriver.
