Your company is considering the replacement of an old delivery van with a new one that is more efficient. The old van cost $40,000 when it was purchased 5 years ago. The old van is being depreciated using the simplified straight line method over a useful life of 8 years. The old van could be sold today for $7,000. The new van has an invoice price of $80,000 and it will cost $6000 to modify the van to carry the company's products. Cost savings from the use of the new van are expected to be $28,000 per year for 5 years, at which time the van will be sold for its estimated salvage value of $18,000. The new van will be depreciated using the simplified straight line method over its 5 year useful life. The company's tax rate is 35%. Working capital is expected to increase by $5000 at the inception of the project, but this amount will be recaptured at the end of year five. What is the incremental free cash flow for year one?
