New Tech (NT) is looking to expand its business. The new business would generate $500,000 per year in sales over the next 5 years. Annual costs would increase by $100,000. An investment in working capital of $10,000 would have to be made initially (and be recovered at the end of the project). The equipment (CCA rate of 30%, half-year rule applies) would cost $400,000. NT estimates that it would be possible to sell the equipment for 20% of its initial value at the end of 5 years. If NT's cost of capital is 10% and its tax rate is 20%, what is the NPV of this project?
