Required:

a. Calculate the net present value of the proposed investment in the drilling and production operation. Assume that the investment will be made at the beginning of 2013, and the net cash inflows from operations will be received in a lump sum at the end of each year. Ignore income taxes, and round answers to the nearest $1.
b. What will the internal rate of return on this investment be relative to the cost of capital? Explain your answer.
c. Differences between estimates made by the task force and actual results would have an effect on the actual rate of return on the project. Identify the significant estimates made by the task force. For each estimate, state the effect on the actual ROI if the estimate turns out to be less than the actual amount finally achieved.
