Boeing just signed a contract to sell a Boeing $737$ aircraft to Air France. Air France will be billed $20$ million payable in one year. The current spot exchange rate is $$1\mathrm{.}05$ per euro and the one$-$year forward rate is $$1\mathrm{.}10$ per euro. The annual interest rate is $6$ percent in the United States and $5$ percent in France. Boeing is concerned with the volatile exchange rate between the dollar and the euro and would like to hedge exchange exposure.

Required:

a$.$ It is considering two hedging alternatives: sell the euro proceeds from the sale forward or borrow euros from Cr$$dit Lyonnaise against the euro receivable. Which alternative would you recommend?

b$.$ Other things being equal, at what forward exchange rate would Boeing be indifferent between the two hedging methods?
