Swissie Debt Costs. 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 CHF$1\mathrm{.}3$ million, a one$-$year period, an initial spot rate of CHF $1\mathrm{.}3000=$$$1\mathrm{.}00,$ a $4\mathrm{.}37\%$ cost of debt, and a $35\%$ tax rate, what is the effective 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$.$ CHF$1\mathrm{.}3000=$$$1\mathrm{.}00?$

b$.$ CHF$1\mathrm{.}2360=$$$1\mathrm{.}00?$

c$.$ CHF$1\mathrm{.}1220=$$$1\mathrm{.}00?$

d$.$ CHF $1\mathrm{.}4470=$$$1\mathrm{.}00?$
