SCM 1st OPP June 2019QUESTION 2 (5 Marks)Answer the following questions by indicating whether the below statements are TRUE or FALSE.2.1 Sustainability is the continuous improvement of a product to make it better and cheaper.2.2 Supply management plays a major role in improving the "bottom line" by driving sales up and costs down.2.3 A small disturbance in the flow of orders generated by a customer does not produce larger disturbances at each upstream stage in the supply chain.2.4 Supply chain partner firms share information and insights in order to form strategic alliances.2.5 One of the key competencies of a supply chain management professional is leadership. The Randolph Teweles Company (RTC) has decided to acquire a new truck. One alternative is to lease the truck on a 4-year guideline contract for a lease payment of $10,000 per year, with payments to be made at the beginning of each year. The lease would include maintenance. Alternatively, RTC could purchase the truck outright for $40,000, financing the purchase by a bank loan for the net purchase price and amortizing the loan over a 4-year period at an interest rate of 10% per year. Under the borrow-to-purchase arrangement, RTC would have to maintain the truck at a cost of $1,000 per year, payable at year end. The truck falls into the MACRS 3-year class. It has a residual value of $10,000, which is the expected market value after 4 years, when RTC plans to replace the truck irrespective of whether it leases or buys. RTC has a marginal federal-plus-state tax rate of 40%.a. What is RTCs PV cost of leasing?b. What is RTCs PV cost of owning? Should the truck be leased or purchased?c. The appropriate discount rate for use in the analysis is the firms after-tax cost of debt. Why?d. The residual value is the least certain cash flow in the analysis. How might RTC incorporate differential riskness of this cash flow into the analysis? One of the following is not a valid title selection technique A. Keeping it less less than 17 characters B.
