Question 1

The paper is 1,400 to 2,100 words in length. The paper provides sufficient background on the topic and previews major points To include the following: ? A recommendation for Ongko?s problems of foreign competition and labor cost with a justification for why they chose that recommendation? ? A discussion on the international capital structure and the cost of capital of Ongko when going global ALSO SEE ATTACHED EXCEL FILE with Financial Budget INFO. Ongko?s Furniture Scenario While many people know that Bali, Indonesia is a beautiful vacation spot, it is also a large furniture manufacturing location in Southeast Asia. Jaya Ongko made furniture for years near his Bali home. The area had an effective supply of timber for the variety of tables and chairs produced by his company. Labor was also relatively inexpensive. In addition, he priced his handcrafted products at a slight premium for the quality they represented. Ongko not only supplied the surrounding countries in Southeast Asia, but also exported his hand-crafted premium products to more than 20 countries worldwide. Overall, life was good for Mr. Ongko. In the late 1990s, two forces combined to cause a large dent in his business. First, a new competitor from overseas entered the furniture market. Using a high-tech approach, the new foreign company provided furniture to exact specifications and did so with rock-bottom prices. Second, the sleepy communities in Bali woke up. One of the largest retailers in the nation?s headquarters was just a few miles down the road, and its influence had expanded considerably. With inexpensive housing, mild weather, beautiful scenery, uncongested roads, a new international airport, and plenty of development, an increase in the population and the number of jobs raised the cost of labor substantially. Ongko watched his profit margins shrink as prices fell and costs rose. After researching his competition to see how they were handling these changes, Ongko saw that many of them were consolidating into larger organizations by merger or acquisition. Being independent, Ongko did not relish the idea of being acquired by a larger competitor and then forced out as the new company squeezed every rupiah it could out of the overhead costs. Initially, Ongko was not a big fan of forming a joint venture, as it would affect time spent with his family in ways that he would not enjoy. When one of his former suppliers in Brazil approached him for a possible acquisition deal, Ongko became interested in the option of expanding his management responsibilities by acquiring this supplier, who had been underperforming in the Brazilian market. One factor that concerned him was the political unrest in Brazil, accompanied by hyperinflation. Prices of goods fluctuated wildly on a daily basis. At the same time, the government kept issuing more paper currency in higher denominations. Banks would restrict the amount of money people could withdraw. The effects on businesses were also devastating. Companies did not want to buy any goods, because they were not sure what price they would pay, and salaries did not keep up with inflation. Alternatively, Ongko observed the foreign competition and their high-tech solution. Essentially, their production utilized a computer-controlled laser lathe to produce exact cuts in the wood. Highly automated, the plant in Norway used very little labor as robots even performed the precise movement and assembly functions. The cost of the technology was immense, as was the reduction in the labor needed for production. In addition, the production, running on a 24-hour basis, could move between products quickly, as the shift-differentials were more than offset by the reduction in labor. Converting his production to this model would be expensive, but he saw how he could also dramatically decrease his production costs. When talking to some of his distributors about their wants, he had another appealing idea. A second competitor, operating only in Denmark, was looking for channels to distribute in Asia. This second potential rival, however, did not operate furniture outlets, favoring instead to rely on chain distributors. Ongko could coordinate his existing distributor network and essentially become a representative for this other manufacturer. While he would retain some of the high-end custom work, he could move his company from primarily manufacturing to primarily distributing. Ongko also had a patented process for creating a coating for his furniture. During production, the process first created a common flame retardant, and upon further processing, the coating is complete and stain-resistant. There was a market for the flame retardant, but not as much of a market for the finished coating. There was another product that Ongko could buy to apply to his furniture that would add the same amount of value to the furniture. ",Hello and thank you.

Question 3

Harriston Electronics builds circuit boards for a variety of applications in industrial equipment. The firm was founded in 1983 by two electrical engineers who left their jobs with the General Electric (GE) Corporation. Its balance sheet for year-end 2006 describes a firm with $1,184,841.00 in assets (book values) and invested capital of approximately $2.2 billion (based on market values). December 31, 2006 Balance Sheet (Book Vlaues) Invested Capital (Market Values) Liabilities and Owner?s capital Current Liabilities Account payable 17,550,000 Notes payable 20,000,000 20,000,000 Other current liabilities 22,266,000 Total current liabilities 59,816,000 20,000,000 Long term debt (7.5% interest paid semiannually due in 2012)650,000,000 624,385,826 Total liabilities 709,816,000 644,385,826 Owner?s capital Common stock ($1 par value per share)20,000,000 Paid in capital 200,025,000 Accumulated earnings 255,000,000 Total owner?s capital 475,025,000 1,560,000,000 Total liabilities and owner?s capital 1,184,841,000 2,204,385,826 Harriston?s CFO, Margaret L. Hones is concerned that its new investments e required to meet an appropriate cost of capital hurdle before capital is committed. Consequently, she initiated a cost of capital study by one of her senior financial analysts, Jack Frist. Shortly after receiving the assignment, Jack called the firm?s investment banker to get input on current capital costs. Jack learned that although the firm?s current debt capital required a 7.5% coupon rate of interest (with annual interest payments and no principal repayments until 2012), the current yield to maturity on similar debt has risen to 8.5%, such that the current market value of the firm?s outstanding bonds had fallen to $624,385,826. Moreover, since the firm?s short term notes were issued within the last 30 days, the 9% contract rate on the notes was the same as the current cost of credit for such notes. a. What are Harriston?s total invested capital and capital structure weights for debt and equity? (Hint: The firm has some short term debt (note payable) that is also interest bearing). b. Assuming a long term U.S. Treasury bond yield of 5.42% and an estimated market risk premium of 5%, what is Harriston?s cost of equity based on the CAPM if the firm?s leveraged equity beta is 1.2? c. What is your estimate of Harriston?s WACC? The firm?s tax rate is 35%,I've attched the template problem-3

Question 4

This a assay about strategic cost management topic. Please Read: Capacity Utilization Management.pdf ( see the attached file) [Pages 1-9, Page 26-28 ?Normal Capacity Models?, Page 34 ?Conclusion?] Discuss: In the Normal Capacity Model ? the authors discusses number of hours of machine use as a key driver for Caterpillar (a publicly traded company that manufactures agricultural products): "The key elements of the Normalized Costing Approach are: a. asset depreciation is calculated on hours of machine use; b. abnormal expenses are eliminated from operational cost pools (e.g., plant modernization costs); c. the behavior of costs within a process is determined and defined within a formula that recognizes key elements affecting the cost of capacity within a process; d. the capacity of the process is then determined, using practical capacity baselines set over a three- to five-year period; e. and normalized cost is then determined by combining cost and capacity information to create a cost estimate under a given set of operating conditions." (Capacity Utilization Management) Are there any limitations to defining a machine?s depreciation by number of hours [think about someone selling a car to you ? what other qualities would you look for]. What other variables would you include in building a cost model for machine depreciation?
