Consider a three-year project with the following information: initial fixed asset investment - $600,000; straight-line depreciation to zero over the five-year life; zero salvage value; price = $45; variable costs = $35; fixed costs = $325,000; The project will require net working capital of $20,000; quantity sold - 85,000 units; tax rate - 23 percent; and cost of capital equal to 15%. a) Use the tax shield approach to obtain the operating cashflows and calculate the NPV of this project. (15 points) I b) What is the NPV if the system qualifies as a five-year MACRS property. (s points) c) Which depreciation method should the company choose? Explain. (5 points) d) How sensitive is the NPV to changes in quantity sold using the NPV calculated in a)? Explain your result. Draw a graph with NPV on the y-axis and unit sales on the x-axis. (10 points) e) What are the break-even unit sales at which NPV is equal to zero? (5 points) Hint for question 2 e): First, obtain the cashflows at which NPV is equal zero, then obtain the unit sales.
