A construction company is deciding to undertake a project. The project is quite profitable as it will generate net cash inflows of $20 million per year for 5 years. However, it will cause pollution to the nearby residents. The company can mitigate this pollution by investing additional 10 million at Year 0 but legally it is not compulsory for it to do so. Undertaking this project would cost $60 million without mitigation. If the firm does invest in mitigation, the annual cash inflows would be $22 million. The risk adjusted WACC is 12%. Calculate the NPV with and without mitigation. a)Calulate the Payback with and without mitgation b)what is the discounted payback with and without mitigation? c)Should the project be undertaken? If so, should the firm do mitigation? (hint: discuss all the criterias you have calculated in earlier parts) d)How should the environmental effects be dealt with when this project is evaluated.
