7. You are the CFO of a drug company, and you must decide whether to invest 15M dollars in R&D for a new drug. If you conduct the R&D, you believe that there is a 4% chance that the research will produce a useful drug. If the research is successful, investment in the drug will require an outlay of 400 million dollars.

The discount rate is 7%.

a) If the research is successful, what is the net present value of the drug cash flows ?

b) If you invest in R&D, you estimate that it will take 2 years to know whether the drug is successful or not. What is the NPV of the R&D investment?
