A mining company is considering a new project. Because the mine has received a permit, the project would be legal; but it would cause significant harm to a nearby river. The firm could spend an additional $11 million at Year 0 to mitigate the environmental problem, but it would not be required to do so. Developing the mine (without mitigation) would require an initial outlay of $69 million, and the expected cash inflows would be $23 million per year for 5 years. If the firm does invest in mitigation, the annual inflows would be $24 million. The risk-adjusted WACC is 10%.

Calculate the NPV and IRR with mitigation. Enter your answer for NPV in millions. For example, an answer of $10,550,000 should be entered as 10.55. Do not round intermediate calculations. Round your answers to two decimal places.
