Please read the problem carefully and do not take from answers already posted of similar problems as there are different numbers in this one. thank you.

This problem is a simplification of reality. It could be, and is, more complicated in actuality.

You are asked to choose among or use two different hedging techniques. You have to explain the hedging technique(s) you use. If you choose one, why is this better than the other one. "Better" can be defined in different ways. One of them is there is more (less) cash flow, as a revenue (expense), for the US firm. There may be others. Another may be that one has features, which the other one has not got. These attributes may make them better.

We are Bechtel, a private US construction firm. We bid to develop the airport and the surrounding area for Thailand. We are not sure whether the Thai transportation authorities will grant us the business, but we hope they will. If we are awarded the contract, for which we bid $ 1 billion, we shall need to buy Thai materials and labor for 2 years. Assume that the purchases we need to make are in one year. The project will be completed in two years from the present. We expect the Thai bhat will revalue in the next 2 years, but we do not know definitely. We have two choices. One is to hedge and paying for the labor and materials in the one yeas, and the other is to leave an open position.

The data we have are the following. The Spot ER, forward ER now and actual spot rate in one year are 24, 30 and 27 bhat per $. The call and put option premia on bhat and dollars for exercise prices of 30 bhat per dollar and 25 bhat per $ are 2% and 1% of the value. The time period of the options is one year. Analyze what the best solution is. Show it

1. mathematically

and 2) verbally.
