We are Bechtel, a private US construction firm. We bid to develop the airport and the surrounding area for Sweden. We are not sure whether the Swedish 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 Swedish 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 Swedish krona 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 year, and the other is to leave an open position. If we hedge, we shall hedge for one year assume, and it will last for 2 years. The data we have are the following. The Spot ER, forward ER now and actual spot rate in one year are 24, 20 and 22 krona per $. The call and put option premia on krona and dollars for exercise prices of 20 krona per dollar and 22 krona 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.
