11. Ashton Bishop is the debt manager for World Telephone, which needs 3.33 billion Euro financing for its operations for three years. Bishop is considering the choice between issuance of debt denominated in Euros (), or U.S. dollars. The U.S. dollar debt will have to be accompanied by a combined interest rate and currency swap. a. What are the risks that World Telephone would assume by entering into the combined interest rate and currency swap? b.
