A larger initial investment is being considered, costing the firm $60M. However, this investment will ensure that 3-years of sales can be predicted at 2M, 3M and 4M units, with a constant fixed unit cost of $65 each year. Sales prices are still expected to grow each year at a rate r = 10%, which is also assumed as the firm's discount rate. a. What is the NPV of this project, using the DCF method? b. Expecting that price is uncertain, assume up and down factors of u = 1.2 and d = 0.8, respectively, and that the probabilities of the up price movements is defined by p= 1+r-d u-d what is the expected NPV of this project?
