Consider a capital expenditure project to purchase and install new equipment costing $16,000. Installation is estimated to be $4000. The equipment has an expected life of 10 years and estimated salvage value of $10,000. The project requires an additional working capital investment of $5000. The project revenues are forecast at $25,000 per year and cash expenses are estimated at $15,000 per year. The firm has a 40% marginal tax rate and a 12% weighted average cost of capital. Assume simplified straight-line depreciation, which is a zero salvage for depreciation purposes.) IO = $25,000
