Korean Airlines (KAL) has just signed a contract with Boeing to purchase two new 747-400's for a total of $70,000,000, with payment in two equal tranches. The first tranche of $30,000,000 has just been paid. The next $40,000,000 is due three months from today. The current spot rate is won 800/$, and permission has been obtained for a forward rate (90 days), won 794/$. The 90 day Eurodollar interest rate is 6.000%, while the 90 day Korean won deposit rate (there is no Euro-won rate) is 5.000%. KAL can borrow in Korea at 6.250%, and can probably borrow in the U.S. dollar market at 9.375%. A three month call option on dollars in the over-the-counter market, for a strike price of won 790/$ sells at a premium of 2.9%, payable at the time the option is purchased. A 90 day put option on dollars, also at a strike price of won 790/$, sells at a premium of 1.9% (assuming a 12% volatility). KAL's foreign exchange advisory service forecasts the spot rate in three months to be won792/$. How should KAL plan to make the payment of $40,000,000 due three months from todayt o Boeing?
