Becky's company is considering an investment project. To start, Becky just needs to purchase an equipment priced at $5,000. The equipment will follow a straight-line depreciation over 10 years. Each year's depreciation is $500. The project will last 3 years. If Becky purchases the equipment for the project, the expected EBIT is $1000 each year in year 1-3. At the end of the year 3, the expected after-tax salvage value of the equipment is $4,200. The tax rate is 20%. Becky can also lease the same equipment for year 1-3 and the annual leasing cost is $600 paid at the end of each year. Becky's company has an optimal capital structure of 50% debt. Its cost of equity is 10% and before-tax cost of debt is 6%. Is the project worth doing? If yes, should Becky buy or lease the equipment?
