Two MNCs have mirror$-$image financing needs for their foreign direct investments: they need to borrow money for $8$ years. The amount of borrowing is $$2,900,000$ or the $$ equivalent amount at the current spot rate of $$1\mathrm{.}3272/.$ Both MNCs$,$ despite of the same credit worthiness, are not well known in the international bond market, and thus pay higher interest rate for the foreign currency borrowing. The U$.$S$.$ MNC pays $7\%$ per annum to borrow euro, whereas the normal borrowing rate for firms of equivalent risk is $6\%$ per annum. The EU MNC pays $9\%$ per annum for dollar borrowing, whereas the normal dollar borrowing cost is $8\%$ per annum for firms of equivalent risk. The $8-$year swaps quotes are: USD: $8\%-8\mathrm{.}1\%$ and EUR: $6\%-6\mathrm{.}1\%.$

$(1)$ Summarize the interest payments resulting from the currency swap for the U$.$S$.$ MNC

$(2)$ Summarize the interest payments resulting from the currency swap for the EU MNC

Answer question $(3)$ to $(5)$ based on the following information: assume one year after the initiation of the currency swap, the dollar interest rate has fallen to $6-6\mathrm{.}15\%$ per annum, the euro interest rate has fallen to $5\mathrm{.}5-5\mathrm{.}75\%$ per annum, and exchange rate changed to $$1\mathrm{.}3343/.$

$(3)$ Calculate the market value of the swap used by the U$.$S$.$ MNC$.$

$(4)$ Calculate the market value of the swap used by the EU MNC$.$

$(5)$ Which MNC would be willing to unwind its original swap contract? Explain with calculation.
