Kingston Kiteboards Incorporated (KKI) has been experiencing very strong demand for its products as kite-boarding continues to take away market share from windsurfing. The company is considering a new facility to manufacture an improved line of kites and another facility to produce a new line of boards. The company estimates that the new kite facility will cost $1,250,000 to construct in Year 0 with a salvage value of $150,000 in Year 12. The board manufacturing facility will cost $1,500,000 in Year 0 with a salvage value of $200,000 in Year 12. Combined annual revenue for the new kites and boards is expected to be $800,000 with annual combined operating costs of $300,000 each year. Management has identified a piece of land where both facilities could be built that could be purchased for $500,000 in Year 0. The management team estimates that the land may be sold for the same value of $500,000 at the end of Year 12. The company uses a discount rate of 10% and a tax rate of only 15%. Assume that the CCA rate of 20% can be applied to the land and the manufacturing facilities. a. Use the present value tax shield approach to determine the net present value (NPV) of combined project involving both new manufacturing facilities. Should KKI proceed with the investment using these assumptions? b. The management team at KKI has decided to take a more conservative approach with some of its estimates. The team feels that the facilities may only last for 10 years and the operating costs may amount to $375,000 per vear. However, the company has successfully negotiateda construction cost of $1,000,000 for the kite facility and $1,200,000 for the board facility (Assume the salvage values are unchanged.) Using the present value tax shield approach, what is the total NPV with these assumptions? Should the company proceed under these revised assumptions
