18 Arnold Inc. is considering a proposal to manufacture high-end protein bars used as food supple-ments by body builders. The project requires use of an existing warehouse, which the firm acquired three years ago for $1 million and which it currently rents out for $120,000. Rental rates are not expected to change going forward. In addition to using the warehouse, the proj-ect requires an upfront investment into machines and other equipment of $1.4 million. This investment can be fully depreciated straight-line over the next 10 years for tax purposes. How-ever, Arnold Inc. expects to terminate the project at the end of eight years and to sell the machines and equipment for $500,000. Finally, the project requires an initial investment into net working capital equal to 10% of predicted first-year sales. Subsequently, net working capitalis 10% of the predicted sales over the following year. Sales of protein bars are expected to be $4.8 million in the first year and to stay constant for eight years. Total manufacturing costs and operating expenses (excluding depreciation) are 80% of sales, and profits are taxed at 30%. a. What are the free cash flows of the project? b. If the cost of capital is 15%, what is the NPV of the project?
