A corporate treasurer will have GBP 1 million to sell in 6 months. She would like to ensure that the funds can be exchanged for no less than $1.42 per GBP. If the exchange rate exceeds $1.48 per GBP, she is willing to accept $1.48 per GBP. If the exchange rate is between $1.42 and $1.48, she will settle for the exchange rate on that day. How could you use options to meet the treasurers requirements?
