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 SF1.5 million, a one year period, an initial spot rate of SF1.5000/S, a 5.000% cost of debt, and a 34% tax rate, what is the effective cost of debt for one year for a c. If the exchange ends the period at SF1.3860/$ : S2 We first calculate the percentage change in the exchange rate, s s=(S1S2)/(S2)100 1.3860 We then calculate the effective cost of debt after exchange rate changes kd=[(1+kdSF)(1+s)]1 d. If the exchange ends the period at SFl.6240/\$: S2 We first calculate the percentage change in the exchange rate, s s=(S1S2)/(S2)100 We then calculate the effective cost of debt after exchange rate changes kd=[(1+kdSF)x(1+s)]1
