5. Foreign Exchange Risk and the Cost of Borrowing Swiss Francs. The chapter demonstrated that a firm borrowing in a foreign currency could potentially end up paying a very different effective rate of interest than what it expected. Using the same baseline values of a debt principal of SF1.4 million, a one-year period, an initial spot rate of SF1.4900/5, a 5.047% cost of debt, and a 30% tax rate, what is the effective after-tax cost of debt for one year for a U.S. dollar-based company if the exchange rate at the end of the period was: a. SF1.4900/S b. SF1.4200/$ c. SF1.3770/5 d. SF1.6030/$ a. If the exchange rate at the end of the period was SF1.4900/$, what is the effective after-tax cost of debt? % (Round to four decimal places.) b. If the exchange rate at the end of the period was SF1.4200/$, what is the effective after-tax cost of debt? % (Round to four decimal places.) c. If the exchange rate at the end of the period was SF1.3770/$, what is the effective after-tax cost of debt? % (Round to four decimal places.) d. If the exchange rate at the end of the period was SF1.6030/$, what is the effective after-tax cost of debt? % (Round to four decimal places.)
