You own a small manufacturing plant that currently generates revenues of $2 million per year. Next year, based upon a decision on a long-term government contract, your revenues will either increase by 20% or decrease by 25%, with equal probability, and stay at that level as long as you operate the plant. Other costs run $1.6 million dollars per year. You can sell the plant at any time to a large conglomerate for $5 million and your cost of capital is 10%.

Assume that it will cost you $1 million to shut down the plant, but you are able to sell the plant for $5 million at any time. What is the current value of the option to sell the plant?
