Figure 2 Because options to abandon, contract, or switch current operations all involve selling a current investment, they are called put options. They become “in the money” when the value that could realize by selling the real underlying asset is greater than the value of the asset in the way it is currently deployed. Decision to defer an investment, expand a current investment, or make a new investment are called call options. They go “in the money” whenever the present value of the new investment exceeds the present value of its costs.
