Problem 14-2 Investment Timing Option: Decision-Tree Analysis The Karns Oil Company is deciding whether to drill for oil on a tract of land that the company owns. The company estimates the project would cost $6 million today. Karns estimates that, once drilled, the oil will generate positive net cash flows of $2.7 million a year at the end of each of the next 4 years. Although the company is fairly confident about its cash flow forecast, in 2 years it will have more information about the local geology and about the price of oil. Karns estimates that if it waits 2 years then the project would cost $7.5 million. Moreover, if it waits 2 years, then there is a 90% chance that the net cash flows would be $3.24 million a year for 4 years and a 10% chance that they would be $1.5 million a year for 4 years. Assume all cash flows are discounted at 10%. a. If the company chooses to drill today, what is the project's net present value? A negative value should be entered with a negative sign. Enter your answer in millions. For example, an answer of $1.2 million should be entered as 1.2, not 1,200,000. Round your answer to two decimal places. $4.70 million b. Using decision-tree analysis, does it make sense to wait 2 years before deciding whether to drill? No, it makes sense to drill today
