The president of Lowell Inc. has asked you to evaluate the proposed acquisition of a new computer. The computer's price is $60,000, and it falls into the MACRS 3-year class (33% in year 1, 45% in year 2, 15% in year 3, and 7% in year 4). Purchase of the computer would require an increase in net operating working capital of $2,000. The computer would increase the firm's before-tax revenues by $20,000 per year but would also increase operating costs by $5,000 per year. The computer is expected to be used for 4 years and then be sold for $25,000. The firm's marginal tax rate is 40 percent, and the project's cost of capital is 14 percent. What is the total value of the terminal year non-operating cash flows (after-tax salvage value + working capital recovered) at the end of Year 4? a. $17,000 b. $18,680 c. $21,000 d. $25,000 e. $27,000
