D. If a firm buys a forward contract, it is in a position to buy the foreign currency when it is needed in the future, but at the price specified today. Hence the firm's payables are covered by this fixed-cost foreign currency as they will know the amount of the domestic currency that will be required to settle the foreign currency denominated payable. This will eliminate the exchange rate risk of the rates moving in the wrong direction prior to the need for the foreign currency.
