Concrete Manufacturing Ltd is considering two alternative investment proposals. The first proposal calls for a major renovation of the company's manufacturing facility. The second involves replacing just a few obsolete pieces of equipment in the facility. The company will choose one project or the other this year, but it will not do both. The cash flows associated with each project appear below and the firm discounts project cash flows at 15%.

Calculate the payback period of each project and based on this criterion, indicate which project you would recommend for acceptance. 2. Calculate the net present value (NPV) of each project and based on this criterion, indicate which project you would recommend for acceptance. 3. Calculate the internal rate of return (IRR) of each project and based on this criterion, indicate which project you would recommend for acceptance. 4. Do you find similar recommendations based on the various criteria? If not explain why? 5. Chart the NPV profiles of these projects. Label the intersection points on the x- and y-axes and the crossover point. 6. Based on this NPV profile analysis and assuming the WACC is 15%, which project would you recommended for acceptance? Why? 7. Based on this NPV profile analysis and assuming the WACC is 25%, which project is recommended? Why?
