Del Mar Fishing Co. is considering a four-year project to improve its production efficiency by purchasing a new machine to pack frozen shrimp. Buying a new machine now (t=0) for $840,000 is estimated to result in no change in revenue, but $120,000 per year in pretax cost savings for the next four years. The firm needs to increase net working capital by $ 200,000 at time 0. The machine will be depreciated straight-line to zero book value over its four-year life. The firm expects that the machine will be sold for $ 220,000 at the end of the fourth year. The required rate of return (i.e., cost of capital) on the project is 15 % and the relevant tax rate is 35%. What are the NPV and IRR of the project? Should Del Mar accept or reject the project? Please be specific
