Your firm is contemplating the purchase of a new $600,000 computer-based order entry system. The system will be depreciated straight-line to zero over its five-year life. It will be worth $64,000 at the end of that time. You will be able to reduce working capital by $79,000 (this is a one-time reduction). The tax rate is 30 percent and the required return on the project is 16 percent. If the pretax cost savings are $204,000 per year, what is the NPV of this project? If the pretax cost savings are $154,000 per year, what is the NPV of this project? At what level of pretax cost savings would you be indifferent between accepting the project and not accepting it?
