Amcor Limited, an Australian company, can issue three years Swiss franc-denominated bonds with a coupon rate of 3.34 per cent. Assuming that Amcor can issue bonds worth A$5.44 million that the current exchange rate of the Swiss franc is A$1.2578, and that the forecasted exchange rate of the franc in each of the next three years is A$1.4207, what is the annual cost in the percentage of financing for the franc-denominated bonds?
