Comparison of Techniques for Hedging Receivables a. Assume that Carbondale Co. expects to receive S$500,000 in one year. The existing spot rate of the Singapore dollar is $.60. The 1-year forward rate of the Singapore dollar is $.62.

One-year call options on Singapore dollars are available with an exercise price of $.60 and a premium of $.03 per unit.

Then compare the most appropriate hedge to an strategy, and decide whether Carbondale should hedge its receivables position. b. Assume that Baton Rouge, Inc., expects to need S$1 million in 1 year. Using any relevant information in part (a) of this question, determine whether a forward hedge, a money market hedge, or a currency options hedge would be most appropriate.
