Microsoft wants to launch a new smartphone and expects to sell 50,000 units per year at a net cash flow of $35 per unit for the next 12 years. Microsofts discount rate is 15%, and the initial investment required is $7.00M. (Hint: You can ignore taxes.)

a) The new smartphone project can be abandoned after the first year in case the project is going poorly, and unnecessary project equipment can be sold off for $6.00M. If all future sales starting in year 2 are revised based on the first years performance, at what volume of expected annual sales (i.e. number of units) would it make sense to abandon the project?

b) Explain in your own words how the $6.00M abandonment value can be interpreted as the opportunity cost of keeping the smartphone project at the end of year 1.

You now think there is a 50% probability that expected sales starting in year 2 will be revised upward to 70,000 units per year for the rest of the project life. There is also a 50% probability the expected sales starting in year 2 will be revised downward to 25,000 units per year for the rest of the project life.

c) What is the NPV of the project? (Hint: You can still sell the equipment at the end of year 1 for $6.00M.)

d) What is the value of the option to abandon the smartphone project?
