Your company is considering the installation of a new production system that will cost $150,000. It is estimated that the system will increase revenues by $65,000 annually for Years 1-4, followed by $50,000 annually for Years 5-7, although operating expenses other than depreciation will also increase by $15,000 per year for Years 1-7. The system will be depreciated on a MACRS basis over 5 years (depreciation rates are 20%, 32%, 19.2%, 11.52%, 11.52% and 5.76% for years 1 to 6 respectively) to a zero book value. If we assume that the tax rate on ordinary income is 40 percent, and the firm's cost of capital for this project is 10 percent, then, as you can calculate, the NPV for this project is $27,161. What is the IRR for this project?
