An oil drilling company must choose between two mutually exclusive extraction projects, and each costs $12 million. Under Plan A, all the oil would be extracted in 1 year, producing a cash flow at t=1 of $14.4 million. Under Plan B, cash flows would be $2.1 million per year for 20 years. The firms WACC is 12 % a. Construct NPV profiles for Plans A and B, identify each projects IRR, and show the approximate crossover rate. b. Is it logical to assume that the firm would take on all available independent, average-risk projects with returns greater than 12%? Is all available projects with returns greater than 12% have been undertaken does this mean that cash flows from past investments have an opportunity cost of only 12 % because all the company can do with these cash flows is to replace money that has cost of 12%? Does this imply that the WACC is the correct reinvestment rate assumption for a projects cash flows? PLEASE SHOW ALL WORK
