Project X that costs $30 million is expected to generate $13m per year for 3 years. Is this project acceptable? d) Consider the following two projects. Project A: IRR = 15%, NPV=500 at r=0% Project B: IRR=20%, NPV=400 at r=0% The crossover rate is 5%. i) Draw the NPV profile. ii) When the projects are mutually exclusive, explain how your project decision can change depending on the cost of capital. e) Explain two critical defects of the PP rule
