Detailed Answer
(a) The requirement is to identify how a company may
hedge exchange risk. Answer (a) is the correct answer because by
buying pounds today with a forward exchange contract, the firm
protects itself against depreciation in the value of the dollar in
relation to the pound. Answer (b) is incorrect because selling
pounds would put the firm in greater risk with respect to appreciation
of the pound. Answers (c) and (d) are incorrect because
buying and selling dollars would do nothing to hedge the value of
the pound.
