A corporation is trying to decide whether or not to buy the patent for a product designed by another company. The decision to buy means an initial investment of $8 million and the demand for the product is not known. If demand is light, the company expects a return of $1.3 million each year for 3 years (assume no cost/revenue afterward). If the demand is moderate the return will be $2.5 million each year for 4 years and a high demand means a return of $4 million each year for 4 years (all figures represent after-tax values). It is estimated the probability of a high demand is 0.4 and the probability of a light demand is 0.2. The firms interest rate (risk-free) is 12%. Calculate the expected net present value.
