Mullum Ltd is considering purchasing new laptop computers. The new laptops have an up-front cost (t=0) of $2,400,000. The laptops are expected to have a four-year life, and will be fully depreciated on a straight-line basis over four years. The company anticipates that after four years, the salvage value will be $200,000. If Mullum goes ahead with the proposed product, it will have an effect on Mullum's net working capital. At the outset, t = 0, net working capital will increase by $100,000. At t = 4, the net operating working capital will be recovered after the project is completed. The new laptops are expected to generate additional revenue of $1,800,000 every year in the four years (t=1, 2, 3, and 4). Each year the operating costs (not including depreciation) are expected to be 50 percent of sales revenue. To fund the project, Mullum will have to borrow $1,000,000 at 6% annual interest rate from the bank and will pay additional annual interest payment of $600,000 starting from year 1. Cost of capital is estimated to be 12 percent per annum. The corporate tax rate is 40 percent. (a) Calculate the project's free cash flows in year 0 and show your calculations.
