Assume that you have just been hired as a financial analyst by Tropical Sweets Inc., a mid-sized Califo
company that specializes in creating exotic candies from tropical fruits such as mangoes, papayas, an
The firm's CEO, George Yamaguchi, recently returned from an industry corporate executive conference i

with the basics of real options, Yamaguchi has asked you to prepare a brief report that the firm's exec
could use to gain at least a cursory understanding of the topics.
a. What are some types of real options? Answer: See Chapter 26 Mini Case Show
b. What are the five steps for analyzing a real option? Answer: See Chapter 26 Mini Case Show
c. Tropical Sweets is considering a project that will cost $70 million and will generate expected cash f
per year for three years. The cost of capital for this type of project is 10 percent and the risk-free rate is
percent. After discussions with the marketing department, you learn that there is a 30 percent chance of
demand, with future cash flows of $45 million per year. There is a 40 percent chance of average demand
cash flows of $30 million per year. If demand is low (a 30 percent chance), cash flows will be only $15 per
What is the expected NPV?
d. Now suppose this project has an investment timing option, since it can be delayed for a year. The c
still be $70 million at the end of the year, and the cash flows for the scenarios will still last three years.
Tropical Sweets will know the level of demand, and will implement the project only if it adds value to th
company. Perform a qualitative assessment of the investment timing option’s value. Answer: See Ch

is. If the company implements the project, it will gain a project, whose value is equal to the present value of
cash flows. Therefore, the present value of a project's future cash flows is analogous to the current value of
stock. The rate of return on the project is equal to its cost of capital. To find the value of a call option
the standard deviation of its rate of return; to find the value of this real option, we need the standard dev

The first step is to find the value of the project's future cash flows, as of the time the option must be e
We also need the standard deviation of the project's value as of the date it must be exercised. Finally, w
the present value of the project's future cash flows.
Standard deviation of return = 42.6%
Direct estimate of s2 = Variance of return = 0.182
CV =Coefficient of Variation = 0.39
Now use the following formula to estimate the variance of the project's rate of return.
t = time until the option expires = 1
Indirect estimate of s2 = 0.142

Use the indirect approach to estimate the variance of the project's rate of return. Start by estimating th
variation, CV, of the project's value at the time the option expires. This was done in an earlier step.

j. What happens to the value of the growth option if the variance of the project’s return is 14.2 percent? What if it
is 50 percent? How might this explain the high valuations of many dot.com companies?
