CHAPTER 8 MANAGEMENT OF TRANSACTION EXPOSURE SUGGESTED ANSWERS AND SOLUTIONS TO END-OF-CHAPTER QUESTIONS ANDPROBLEMSQUESTIONS1. How would you define transaction exposure? How is it different from economic exposure?Answer: Transaction exposure is the sensitivity of realized domestic currency values of the firm‟s contractual cash flows denominated in foreign currencies to unexpected changes in exchange rates. Unlike economic exposure, transaction exposure is well-defined and short-term.2. Discuss and compare hedging transaction exposure using the forward contract vs. money market instruments. When do the alternative hedging approaches produce the same result?Answer: Hedging transaction exposure by a forward contract is achieved by selling or buying foreign currency receivables or payables forward. On the other hand, money market hedge is achieved by borrowing or lending the present value of foreign currency receivables or payables, thereby creating offsetting foreign currency positions. If the interest rate parity is holding, the two hedging methods are equivalent.3. Discuss and compare the costs of hedging via the forward contract and the options contract.Answer: There is no up-front cost of hedging by forward contracts. In the case of options hedging, however, hedgers should pay the premiums for the contracts up-front. The cost of forward hedging, however, may be realized ex post when the hedger regrets his/her hedging decision.4. What are the advantages of a currency options contract as a hedging tool compared with the forward contract?Answer: The main advantage of using options contracts for hedging is that the hedger can decide whether to exercise options upon observing the realized future exchange rate. Options thus provide a hedge against ex post regret that forward hedger might have to suffer. Hedgers can only eliminate the downside risk while retaining the upside potential.5. Suppose your company has purchased a put option on the German mark to manage exchange exposure associated with an account receivable denominated in that currency. In this case, your company can be said to have an …insurance‟ policy on its receivable. Explain in what sense this is so.Answer: Your company in this case knows in advance that it will receive a certain minimum dollar amount no matter what might happen to the $/€exchange rate. Furthermore, if the German mark appreciates, your company will benefit from the rising euro.6. Recent surveys of corporate exchange risk management practices indicate that many U.S. firms simply do not hedge. How would you explain this result?Answer: There can be many possible reasons for this. First, many firms may feel that they are not really exposed to exchange risk due to product diversification, diversified markets for their products, etc. Second, firms may be using self-insurance against exchange risk. Third, firms may feel that shareholders can diversify exchange risk themselves, rendering corporate risk management unnecessary.7. Should a firm hedge? Why or why not?Answer: In a perfect capital market, firms may not need to hedge exchange risk. But firms can add to their value by hedging if markets are imperfect. First, if management knows about the firm‟s exposure better than shareholders, the firm, not its shareholders, should hedge. Second, firms may be able to hedge at a lower cost. Third, if default costs are significant, corporate hedging can be justifiable because it reduces the probability of default. Fourth, if the firm faces progressive taxes, it can reduce tax obligations by hedging which stabilizes corporate earnings.8. Using an example, discuss the possible effect of hedging on a firm‟s tax obligations.Answer: One can use an example similar to the one presented in the chapter.9. Explain contingent exposure and discuss the advantages of using currency options to manage this type of currency exposure.Answer: Companies may encounter a situation where they may or may not face currency exposure. In this situation, companies need options, not obligations, to buy or sell a given amount of foreign exchange they may or may not receive or have to pay. If companies either hedge using forward contracts or do not hedge at all, they may face definite currency exposure.10. Explain cross-hedging and discuss the factors determining its effectiveness.Answer: Cross-hedging involves hedging a position in one asset by taking a position in another asset. The effectiveness of cross-hedging would depend on the strength and stability of the relationship between the two assets.PROBLEMS1. Cray Research sold a super computer to the Max Planck Institute in Germany on credit and invoiced €10 million payable in six months. Currently, the six-month forward exchange rate is $1.10/€ and the foreign exchange advisor for Cray Research predicts that the spot rate is likely to be $1.05/€ in six months.(a) What is the expected gain/loss from the forward hedging?(b) If you were the financial manager of Cray Research, would you recommend hedging this euro receivable? Why or why not?(c) Suppose the foreign exchange advisor predicts that the future spot rate will be the same as the forward exchange rate quoted today. Would you recommend hedging in this case? Why or why not?Solution: (a) Expected gain($) = 10,000,000(1.10 – 1.05)= 10,000,000(.05)= $500,000.(b) I would recommend hedging because Cray Research can increase the expected dollar receipt by $500,000 and also eliminate the exchange risk.(c) Since I eliminate risk without sacrificing dollar receipt, I still would recommend hedging.2. IBM purchased computer chips from NEC, a Japanese electronics concern, and was billed ¥250 million payable in three months. Currently, the spot exchange rate is ¥105/$ and the three-month forward rate is ¥100/$. The three-month money market interest rate is 8 percent per annum in the U.S. and 7 percent per annum in Japan. The management of IBM decided to use the money market hedge to deal with this yen account payable.(a) Explain the process of a money market hedge and compute the dollar cost of meeting the yen obligation.(b) Conduct the cash flow analysis of the money market hedge.Solution: (a). Let‟s first compute the PV of ¥250 million, i.e.,250m/1.0175 = ¥245,700,245.7So if the above yen amount is invested today at the Japanese interest rate for three months, the maturity value will be exactly equal to ¥25 million which is the amount of payable.To buy the above yen amount today, it will cost:$2,340,002.34 = ¥250,000,000/105.The dollar cost of meeting this yen obligation is $2,340,002.34 as of today.(b)___________________________________________________________________Transaction CF0 CF1____________________________________________________________________1.

You plan to visit Geneva, Switzerland in three months to attend an international business conference. You expect to incur the total cost of SF 5,000 for lodging, meals and transportation during your stay. As of today, the spot exchange rate is $0.60/SF and the three-month forward rate is $0.63/SF. You can buy the three-month call option on SF with the exercise rate of $0.64/SF for the premium of $0.05 per SF. Assume that your expected future spot exchange rate is the same as the forward rate. The three-month interest rate is 6 percent per annum in the United States and 4 percent per annum in Switzerland.(a) Calculate your expected dollar cost of buying SF5,000 if you choose to hedge via call option on SF.(b) Calculate the future dollar cost of meeting this SF obligation if you decide to hedge using a forward contract.(c) At what future spot exchange rate will you be indifferent between the forward and option market hedges?(d) Illustrate the future dollar costs of meeting the SF payable against the future spot exchange rate under both the options and forward market hedges.Solution: (a) Total option premium = (.05)(5000) = $250. In three months, $250 is worth $253.75 = $250(1.015). At the expected future spot rate of $0.63/SF, which is less than the exercise price, you don‟t expect to exercise options. Rather, you expect to buy Swiss franc at $0.63/SF. Since you are going to buy SF5,000, you expect to spend $3,150 (=.63x5,000). Thus, the total expected cost of buying SF5,000 will be the sum of $3,150 and $253.75, i.e., $3,403.75.(b) $3,150 = (.63)(5,000).(c) $3,150 = 5,000x + 253.75, where x represents the break-even future spot rate. Solving for x, we obtain x = $0.57925/SF. Note that at the break-even future spot rate, options will not be exercised.(d) If the Swiss franc appreciates beyond $0.64/SF, which is the exercise price of call option, you will exercise the option and buy SF5,000 for $3,200. The total cost of buying SF5,000 will be $3,453.75 = $3,200 + $253.75.This is the maximum you will pay.4. Boeing just signed a contract to sell a Boeing 737 aircraft to Air France. Air France will be billed €20 million which is payable in one year. The current spot exchange rate is $1.05/€ and the one -year forward rate is $1.10/€. The annual interest rate is 6.0% in the U.S. and5.0% in France. Boeing is concerned with the volatile exchange rate between the dollar and the euro and would like to hedge exchange exposure. (a) It is considering two hedging alternatives: sell the euro proceeds from the sale forward or borrow euros from the Credit Lyonnaise against the euro receivable. Which alternative would you recommend? Why?(b) Other things being equal, at what forward exchange rate would Boeing be indifferent between the two hedging methods?Solution: (a) In the case of forward hedge, the future dollar proceeds will be (20,000,000)(1.10) = $22,000,000. In the case of money market hedge (MMH), the firm has to first borrow the PV of its euro receivable, i.e., 20,000,000/1.05 =€19,047,619. Then the firm should exchange this euro amount into dollars at the current spot rate to receive: (€19,047,619)($1.05/€) = $20,000,000, which can be invested at the dollar interest rate for one year to yield:$20,000,000(1.06) = $21,200,000.Clearly, the firm can receive $800,000 more by using forward hedging.(b) According to IRP, F = S(1+i $)/(1+i F ). Thus the “indifferent” forward rate will be:F = 1.05(1.06)/1.05 = $1.06/€. $ Cost Options hedge Forward hedge $3,453.75 $3,150 0 0.579 0.64 (strike price) $/SF$253.755. Suppose that Baltimore Machinery sold a drilling machine to a Swiss firm and gave the Swiss client a choice of paying either $10,000 or SF 15,000 in three months.(a) In the above example, Baltimore Machinery effectively gave the Swiss client a free option to buy up to $10,000 dollars using Swiss franc. What is the …implied‟ exercise exchange rate?(b) If the spot exchange rate turns out to be $0.62/SF, which currency do you think the Swiss client will choose to use for payment? What is the value of this free option for the Swiss client?(c) What is the best way for Baltimore Machinery to deal with the exchange exposure?Solution: (a) The implied exercise (price) rate is: 10,000/15,000 = $0.6667/SF.(b) If the Swiss client chooses to pay $10,000, it will cost SF16,129 (=10,000/.62). Since the Swiss client has an option to pay SF15,000, it will choose to do so. The value of this option is obviously SF1,129 (=SF16,129-SF15,000).(c) Baltimore Machinery faces a contingent exposure in the sense that it may or may not receive SF15,000 in the future. The firm thus can hedge this exposure by buying a put option on SF15,000.6. Princess Cruise Company (PCC) purchased a ship from Mitsubishi Heavy Industry. PCC owes Mitsubishi Heavy Industry 500 million yen in one year. The current spot rate is 124 yen per dollar and the one-year forward rate is 110 yen per dollar. The annual interest rate is 5% in Japan and 8% in the U.S. PCC can also buy a one-year call option on yen at the strike price of $.0081 per yen for a premium of .014 cents per yen.(a) Compute the future dollar costs of meeting this obligation using the money market hedge and the forward hedges.(b) Assuming that the forward exchange rate is the best predictor of the future spot rate, compute the expected future dollar cost of meeting this obligation when the option hedge is used.(c) At what future spot rate do you think PCC may be indifferent between the option and forward hedge?Solution: (a) In the case of forward hedge, the dollar cost will be 500,000,000/110 = $4,545,455. In the case of money market hedge, the future dollar cost will be: 500,000,000(1.08)/(1.05)(124)= $4,147,465.(b) The option premium is: (.014/100)(500,000,000) = $70,000. Its future value will be $70,000(1.08) = $75,600.At the expected future spot rate of $.0091(=1/110), which is higher than the exercise of $.0081, PCC will exercise its call option and buy ¥500,000,000 for $4,050,000 (=500,000,000x.0081).The total expected cost will thus be $4,125,600, which is the sum of $75,600 and $4,050,000.(c) When the option hedge is used, PCC will spend “at most” $4,125,000. On the other hand, when the forward hedging is used, PCC will have to spend $4,545,455 regardless of the future spot rate. This means that the options hedge dominates the forward hedge. At no future spot rate, PCC will be indifferent between forward and options hedges.7. Airbus sold an aircraft, A400, to Delta Airlines, a U.S. company, and billed $30 million payable in six months. Airbus is concerned with the euro proceeds from international sales and would like to control exchange risk. The current spot exchang e rate is $1.05/€ and six-month forward exchange rate is $1.10/€ at the moment. Airbus can buy a six-month put option on U.S. dollars with a strike price of €0.95/$ for a premium of €0.02 per U.S. dollar. Currently, six-month interest rate is 2.5% in the euro zone and 3.0% in the U.S.pute the guaranteed euro proceeds from the American sale if Airbus decides to hedge using aforward contract.b.If Airbus decides to hedge using money market instruments, what action does Airbus need to take?What would be the guaranteed euro proceeds from the American sale in this case?c.If Airbus decides to hedge using put options on U.S. dollars, what would be the …expected‟ europroceeds from the American sale? Assume that Airbus regards the current forward exchange rate as an unbiased predictor of the future spot exchange rate.d.At what future spot exchange rate do you think Airbus will be indifferent between the option andmoney market hedge?Solution:a. Airbus will sell $30 million forward for €27,272,727 = ($30,000,000) / ($1.10/€).b. Airbus will borrow the present value of the dollar receivable, i.e., $29,126,214 = $30,000,000/1.03, and then sell the dollar proceeds spot for euros: €27,739,251. This is the euro amount that Airbus is going to keep.c. Since th e expected future spot rate is less than the strike price of the put option, i.e., €0.9091< €0.95, Airbus expects to exercise the option and receive €28,500,000 = ($30,000,000)(€0.95/$). This is gross proceeds. Airbus spent €600,000 (=0.02x30,000,000) upfr ont for the option and its future cost is equal to €615,000 = €600,000 x 1.025. Thus the net euro proceeds from the American sale is €27,885,000, which is the difference between the gross proceeds and the option costs.d. At the indifferent future spot rate, the following will hold:€28,432,732 = S T (30,000,000) - €615,000.Solving for S T, we obtain the “indifference” future spot exchange rate, i.e., €0.9683/$, or $1.0327/€.Note that €28,432,732 is the future value of the proceeds under money market hed ging:€28,432,732 = (€27,739,251) (1.025).Suggested solution for Mini Case: Chase Options, Inc.[See Chapter 13 for the case text]Chase Options, Inc.Hedging Foreign Currency Exposure Through Currency OptionsHarvey A. PoniachekI. Case SummaryThis case reviews the foreign exchange options market and hedging. It presents various international transactions that require currency options hedging strategies by the corporations involved. Seven transactions under a variety of circumstances are introduced that require hedging by currency options. The transactions involve hedging of dividend remittances, portfolio investment exposure, and strategic economic competitiveness. Market quotations are provided for options (and options hedging ratios), forwards, and interest rates for various maturities.II. Case Objective.The case introduces the student to the principles of currency options market and hedging strategies. The transactions are of various types that often confront companies that are involved in extensive international business or multinational corporations. The case induces students to acquire hands-on experience in addressing specific exposure and hedging concerns, including how to apply various market quotations, which hedging strategy is most suitable, and how to address exposure in foreign currency through cross hedging policies.III. Proposed Assignment Solution1. The company expects DM100 million in repatriated profits, and does not want the DM/$ exchange rate at which they convert those profits to rise above 1.70. They can hedge this exposure using DM put options with a strike price of 1.70. If the spot rate rises above 1.70, they can exercise the option, while ifthat rate falls they can enjoy additional profits from favorable exchange rate movements.To purchase the options would require an up-front premium of:DM 100,000,000 x 0.0164 = DM 1,640,000.With a strike price of 1.70 DM/$, this would assure the U.S. company of receiving at least:DM 100,000,000 – DM 1,640,000 x (1 + 0.085106 x 272/360)= DM 98,254,544/1.70 DM/$ = $57,796,791by exercising the option if the DM depreciated. Note that the proceeds from the repatriated profits are reduced by the premium paid, which is further adjusted by the interest foregone on this amount.However, if the DM were to appreciate relative to the dollar, the company would allow the option to expire, and enjoy greater dollar proceeds from this increase.Should forward contracts be used to hedge this exposure, the proceeds received would be:DM100,000,000/1.6725 DM/$ = $59,790,732,regardless of the movement of the DM/$ exchange rate. While this amount is almost $2 million more than that realized using option hedges above, there is no flexibility regarding the exercise date; if this date differs from that at which the repatriate profits are available, the company may be exposed to additional further current exposure. Further, there is no opportunity to enjoy any appreciation in the DM.If the company were to buy DM puts as above, and sell an equivalent amount in calls with strike price 1.647, the premium paid would be exactly offset by the premium received. This would assure that the exchange rate realized would fall between 1.647 and 1.700. If the rate rises above 1.700, the company will exercise its put option, and if it fell below 1.647, the other party would use its call; for any rate in between, both options would expire worthless. The proceeds realized would then fall between:DM 100,00,000/1.647 DM/$ = $60,716,454andDM 100,000,000/1.700 DM/$ = $58,823,529.This would allow the company some upside potential, while guaranteeing proceeds at least $1 million greater than the minimum for simply buying a put as above.Buy/Sell OptionsDM/$Spot Put Payoff “Put”Profits Call Payoff“Call”Profits Net Profit1.60 (1,742,846) 0 1,742,846 60,716,454 60,716,454 1.61 (1,742,846) 0 1,742,846 60,716,454 60,716,454 1.62 (1,742,846) 0 1,742,846 60,716,454 60,716,454 1.63 (1,742,846) 0 1,742,846 60,716,454 60,716,454 1.64 (1,742,846) 0 1,742,846 60,716,454 60,716,454 1.65 (1,742,846) 60,606,061 1,742,846 0 60,606,061 1.66 (1,742,846) 60,240,964 1,742,846 0 60,240,964 1.67 (1,742,846) 59,880,240 1,742,846 0 59,880,240 1.68 (1,742,846) 59,523,810 1,742,846 0 59,523,810 1.69 (1,742,846) 59,171,598 1,742,846 0 59,171,598 1.70 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.71 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.72 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.73 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.74 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.75 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.76 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.77 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.78 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.79 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.80 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.81 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.82 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.83 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.84 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.85 (1,742,846) 58,823,529 1,742,846 0 58,823,529Since the firm believes that there is a good chance that the pound sterling will weaken, locking them into a forward contract would not be appropriate, because they would lose the opportunity to profit from this weakening. Their hedge strategy should follow for an upside potential to match their viewpoint. Therefore, they should purchase sterling call options, paying a premium of:5,000,000 STG x 0.0176 = 88,000 STG.If the dollar strengthens against the pound, the firm allows the option to expire, and buys sterling in the spot market at a cheaper price than they would have paid for a forward contract; otherwise, the sterling calls protect against unfavorable depreciation of the dollar.Because the fund manager is uncertain when he will sell the bonds, he requires a hedge which will allow flexibility as to the exercise date. Thus, options are the best instrument for him to use. He can buy A$ puts to lock in a floor of 0.72 A$/$.

The German company is bidding on a contract which they cannot be certain of winning. Thus, the need to execute a currency transaction is similarly uncertain, and using a forward or futures as a hedge is inappropriate, because it would force them to perform even if they do not win the contract.Using a sterling put option as a hedge for this transaction makes the most sense. For a premium of:12 million STG x 0.0161 = 193,200 STG,they can assure themselves that adverse movements in the pound sterling exchange rate will not diminish the profitability of the project (and hence the feasibility of their bid), while at the same time allowing the potential for gains from sterling appreciation.5. Since AMC in concerned about the adverse effects that a strengthening of the dollar would have on its business, we need to create a situation in which it will profit from such an appreciation. Purchasing a yen put or a dollar call will achieve this objective. The data in Exhibit 1, row 7 represent a 10 percent appreciation of the dollar (128.15 strike vs. 116.5 forward rate) and can be used to hedge against a similar appreciation of the dollar.For every million yen of hedging, the cost would be:Yen 100,000,000 x 0.000127 = 127 Yen.To determine the breakeven point, we need to compute the value of this option if the dollar appreciated 10 percent (spot rose to 128.15), and subtract from it the premium we paid. This profit would be compared with the profit earned on five to 10 percent of AMC‟s sales (which would be lost as a result of the dollar appreciation). The number of options to be purchased which would equalize these two quantities would represent the breakeven point.Example #5:Hedge the economic cost of the depreciating Yen to AMC.If we assume that AMC sales fall in direct proportion to depreciation in the yen (i.e., a 10 percent decline in yen and 10 percent decline in sales), then we can hedge the full value of AMC‟s sales. I have assumed $100 million in sales.1) Buy yen puts# contracts needed = Expected Sales *Current ¥/$ Rate / Contract size9600 = ($100,000,000)(120¥/$) / ¥1,250,0002) Total Cost = (# contracts)(contract size)(premium)$1,524,000 = (9600)( ¥1,250,000)($0.0001275/¥)3) Floor rate = Exercise – Premium128.1499¥/$ = 128.15¥/$ - $1,524,000/12,000,000,000¥4) The payoff changes depending on the level of the ¥/$ rate.

Chapter 8Relationships Among Inflation,Interest Rates, and Exchange Rates Lecture OutlinePurchasing Power Parity (PPP)Interpretations of PPPRationale Behind PPP TheoryDerivation of PPPUsing PPP to Estimate Exchange Rate EffectsGraphic Analysis of PPPTesting the PPP TheoryWhy PPP Does Not OccurPPP in the Long RunInternational Fisher Effect (IFE)Implications of the IFE for Foreign InvestorsDerivation of the IFEGraphic Analysis of the IFETests of the IFEWhy the IFE Does Not OccurComparison of IRP, PPP, and IFE TheoriesChapter ThemeThis chapter discusses the relationship between inflation and exchange rates according to the purchasing power parity (PPP) theory. Since this is one of the most popular subjects in inter-national finance, it is covered thoroughly. While PPP is a relevant theory, it should be emphasized that PPP will not always hold in reality. It does however, provide a foundation in understanding how inflation can affect exchange rates. The international Fisher effect (IFE) is also discussed in this chapter. This theory is also very important. Yet, it should again be emphasized that this theory does not always hold. If the PPP and IFE theories held consistently, decision making by MNCs would be much easier. Because these theories do not hold consistently, an MNC’s decision making is very challenging.Topics to Stimulate Class Discussion1. Provide reasoning for why highly inflated countries such as Brazil tend to have weak homecurrencies.2. Identify the inflation rate of your home country and some well-known foreign country. Thenidentify the percentage change of your home currency with respect to that foreign country.Did the currency change in the direction and by the magnitude that you would have expected according to PPP? If not, offer possible reasons for this discrepancy.3. Identify the quoted one-year interest rates in your home country and in a well-known foreigncountry as of one year ago. Also determine how your home currency changed relative to this foreign currency over the last year. Did the currency change according to the IFE theory? If not, does this information disprove IFE? Elaborate.4. Provide a simple explanation of the difference between interest rate parity (from the previouschapter), PPP (from this chapter), and IFE (from this chapter).Critical debateDoes PPP Eliminate Concerns about Long-Term Exchange Rate Risk?Proposition Yes. Studies have shown that exchange rate movements are related to inflation differentials in the long run. Based on PPP, the currency of a high-inflation country will depreciate against the home currency. A subsidiary in that country should generate inflated revenue from the inflation, which will help offset the adverse exchange effects when its earnings are remitted to the parent. If a firm is focused on long-term performance, the deviations from PPP will offset over time. In some years, the exchange rate effects may exceed the inflation effects, and in other years the inflation effects will exceed the exchange rate effects.Opposing view No. Even if the relationship between inflation and exchange rate effects is consistent, this does not guarantee that the effects on the firm will be offsetting. A subsidiary in a high-inflation country will not necessarily be able to adjust its price level to keep up with the increased costs of doing business there. The effects vary with each MNC’s situation. Even if the subsidiary can raise its prices to match the rising costs, there are short-term deviations from PPP. The investors who invest in an MNC’s stock may be concerned about short-term deviations fromPPP, because they will not necessarily hold the stock for the long term. Thus, investors may prefer that firms manage in a manner that reduces the volatility in their performance in short-run and long-run periods.With whom do you agree? State your reasons Examine the exchange rate policies of the major multinationals by referring to their annual reports. The Forbes listing of major multinationals on the web is a good starting point. In particular, consult the reports of Renault (France) and Phillips (Holland).ANSWER: It is possible that inflation and exchange rate effects will offset over the long run. However, many investors will not be satisfied because they may invest in the firm for just a few years or even a shorter term. Thus, they will prefer that MNCs assess their exposure to exchange rate risk and attempt to limit the risk.Answers to End of Chapter Questions1. PPP. Explain the theory of purchasing power parity (PPP). Based on this theory, what is ageneral forecast of the values of currencies in countries with high inflation?ANSWER: PPP suggests that the purchasing power of a consumer will be similar when purchasing goods in a foreign country or in the home country. If inflation in a foreign country differs from inflation in the home country, the exchange rate will adjust to maintain equal purchasing power.Currencies in countries with high inflation will be weak according to PPP, causing the purchasing power of goods in the home country versus these countries to be similar.2. Rationale of PPP. Explain the rationale of the PPP theory.ANSWER: When inflation is high in a particular country, foreign demand for goods in that country will decrease. In addition, that country’s demand for foreign goods should increase.Thus, the home currency of that country will weaken; this tendency should continue until the currency has weakened to the extent that a foreign country’s goods are no more attractive than the home country’s goods. Inflation differentials are offset by exchange rate changes. 3. Testing PPP. Explain how you could determine whether PPP exists. Describe a limitation intesting whether PPP holds.ANSWER: One method is to choose two countries and compare the inflation differential to the exchange rate change for several different periods. Then, determine whether the exchange rate changes were similar to what would have been expected under PPP theory.A second method is to choose a variety of countries and compare the inflation differential ofeach foreign country relative to the home country for a given period. Then, determine whether the exchange rate changes of each foreign currency were what would have been expected based on the inflation differentials under PPP theory.A limitation in testing PPP is that the results will vary with the base period chosen. The baseperiod should reflect an equilibrium position, but it is difficult to determine when such a period exists.4. Testing PPP. Inflation differentials between the U.S. and other industrialized countries havetypically been a few percentage points in any given year. Yet, in many years annual exchange rates between the corresponding currencies have changed by 10 percent or more.What does this information suggest about PPP?ANSWER: The information suggests that there are other factors besides inflation differentials that influence exchange rate movements. Thus, the exchange rate movements will not necessarily conform to inflation differentials, and therefore PPP will not necessarily hold.5. Limitations of PPP. Explain why PPP does not hold.ANSWER: PPP does not consistently hold because there are other factors besides inflation that influences exchange rates. Thus, exchange rates will not move in perfect tandem with inflation differentials. In addition, there may not be substitutes for traded goods. Therefore, even when a country’s inflation increases, the foreign demand for its products will not necessarily decrease (in the manner suggested by PPP) if substitutes are not available.6. Implications of IFE. Explain the international Fisher effect (IFE). What is the rationale forthe existence of the IFE? What are the implications of the IFE for firms with excess cash that consistently invest in foreign Treasury bills? Explain why the IFE may not hold.ANSWER: The IFE suggests that a currency’s value will adjust in accordance with the differential in interest rates between two countries.The rationale is that if a particular currency exhibits a high nominal interest rate, this may reflect a high anticipated inflation. Thus, the inflation will place downward pressure on the currency’s value if it occurs.The implications are that a firm that consistently purchases foreign Treasury bills will on average earn a similar return as on domestic Treasury bills.The IFE may not hold because exchange rate movements react to other factors in addition to interest rate differentials. Therefore, an exchange rate will not necessarily adjust in accordance with the nominal interest rate differentials, so that IFE may not hold.7. Implications of IFE. Assume UK interest rates are generally above foreign interest rates.What does this suggest about the future strength or weakness of the pound based on the IFE?Should UK investors invest in foreign securities if they believe in the IFE? Should foreign investors invest in UK securities if they believe in the IFE?ANSWER: The IFE would suggest that the pound will depreciate over time if UK interest rates are currently higher than foreign interest rates. Consequently, foreign investors who purchased UK securities would on average receive a similar yield as what they receive in their own country, and UK investors who purchased foreign securities would on average receive a yield similar to UK rates.8. Comparing Parity Theories. Compare and contrast interest rate parity (discussed in theprevious chapter), purchasing power parity (PPP), and the international Fisher effect (IFE).ANSWER: Interest rate parity can be evaluated using data at any one point in time to determine the relationship between the interest rate differential of two countries and the forward premium (or discount). PPP suggests a relationship between the inflation differential of two countries and the percentage change in the spot exchange rate over time. IFE suggestsa relationship between the interest rate differential of two countries and the percentagechange in the spot exchange rate over time. IFE is based on nominal interest rate differentials, which are influenced by expected inflation. Thus, the IFE is closely related to PPP.9. Real Interest Rate. One assumption made in developing the IFE is that all investors in allcountries have the same real interest rate. What does this mean?ANSWER: The real return is the nominal return minus the inflation rate. If all investors require the same real return, then the differentials in nominal interest rates should be solely due to differentials in anticipated inflation among countries.10. Interpreting Inflationary Expectations. If investors in the UK and Canada require the samereal interest rate, and the nominal rate of interest is 2 percent higher in Canada, what does this imply about expectations of UK inflation and Canadian inflation? What do these inflationary expectations suggest about future exchange rates?ANSWER: Expected inflation in Canada is 2 percent above expected inflation in the UK. If these inflationary expectations come true, PPP would suggest that the value of the Canadian dollar should depreciate by 2 percent against the pound.11. PPP Applied to the Euro. Assume that several European countries that use the euro as theircurrency experience higher inflation than the United States, while two other European countries that use the euro as their currency experience lower inflation than the United States.According to PPP, how will the euro’s value against the dollar be affected?ANSWER: The high European inflation overall would reduce the U.S. demand for European products, increase the European demand for U.S. products, and cause the euro to depreciate against the dollar.According to the PPP theory, the euro's value would adjust in response to the weighted inflation rates of the European countries that are represented by the euro relative to the inflation in the U.S. If the European inflation rises, while the U.S. inflation remains low, there would be downward pressure on the euro.12. Source of Weak Currencies. Currencies of some Latin American countries, such as Braziland Venezuela, frequently weaken against most other currencies. What concept in this chapter explains this occurrence? Why don’t all U.S.-based MNCs use forward contracts to hedge their future remittances of funds from Latin American countries to the U.S. even if they expect depreciation of the currencies against the dollar?ANSWER: Latin American countries typically have very high inflation, as much as 200 percent or more. PPP theory would suggest that currencies of these countries will depreciateagainst the U.S. dollar (and other major currencies) in order to retain purchasing power across countries. The high inflation discourages demand for Latin American imports and places downward pressure in their Latin American currencies. Depreciation of the currencies offsets the increased prices on Latin American goods from the perspective of importers in other countries.Interest rate parity forces the forward rates to contain a large discount due to the high interest rates in Latin America, which reflects a disadvantage of hedging these currencies. The decision to hedge makes more sense if the expected degree of depreciation exceeds the degree of the forward discount. Also, keep in mind that some remittances cannot be perfectly hedged anyway because the amount of future remittances is uncertain.13. PPP. Japan has typically had lower inflation than the United States. How would one expectthis to affect the Japanese yen’s value? Why does this expected relationship not always occur?ANSWER: Japan’s low inflation should place upward pressure on the yen’s value. Yet, other factors can sometimes offset this pressure. For example, Japan heavily invests in U.S.securities, which places downward pressure on the yen’s value.14. IFE. Assume that the nominal interest rate in Mexico is 48 percent and the interest rate in theUnited States is 8 percent for one-year securities that are free from default risk. What does the IFE suggest about the differential in expected inflation in these two countries? Using this information and the PPP theory, describe the expected nominal return to U.S. investors who invest in Mexico.ANSWER: If investors from the U.S. and Mexico required the same real (inflation-adjusted) return, then any difference in nominal interest rates is due to differences in expected inflation. Thus, the inflation rate in Mexico is expected to be about 40 percent above the U.S.inflation rate.According to PPP, the Mexican peso should depreciate by the amount of the differential between U.S. and Mexican inflation rates. Using a 40 percent differential, the Mexican peso should depreciate by about 40 percent. Given a 48 percent nominal interest rate in Mexico and expected depreciation of the peso of 40 percent, U.S. investors will earn about 8 percent.(This answer used the inexact formula, since the concept is stressed here more than precision.)15. IFE. Shouldn’t the IFE discourage investors from attempting to capitalize on higher foreigninterest rates? Why do some investors continue to invest overseas, even when they have no other transactions overseas?ANSWER: According to the IFE, higher foreign interest rates should not attract investors because these rates imply high expected inflation rates, which in turn imply potential depreciation of these currencies. Yet, some investors still invest in foreign countries where nominal interest rates are high. This may suggest that some investors believe that (1) the anticipated inflation rate embedded in a high nominal interest rate is overestimated, or (2) the potentially high inflation will not cause substantial depreciation of the foreign currency (which could occur if adequate substitute products were not available elsewhere), or (3) thereare other factors that can offset the possible impact of inflation on the foreign currency’s value.16. Changes in Inflation. Assume that the inflation rate in Brazil is expected to increasesubstantially. How will this affect Brazil’s nominal interest rates and the value of its currency (called the real)? If the IFE holds, how will the nominal return to UK investors who invest in Brazil be affected by the higher inflation in Brazil? Explain.ANSWER: Brazil’s nominal interest rate would likely increase to maintain the real return required by Brazilian investors. The Brazilian real would be expected to depreciate according to the IFE. If the IFE holds, the return to UK investors who invest in Brazil would not be affected. Even though they now earn a higher nominal interest rate, the expected decline in the Brazilian real offsets the additional interest to be earned.17. Comparing PPP and IFE. How is it possible for PPP to hold if the IFE does not?ANSWER: For the IFE to hold, the following conditions are necessary:(1) investors across countries require the same real returns,(2) the expected inflation rate embedded in the nominal interest rate occurs,(3) the exchange rate adjusts to the inflation rate differential according to PPP.If conditions (1) or (2) do not hold, PPP may still hold, but investors may achieve consistently higher returns when investing in a foreign country’s securities. Thus, IFE would be refuted.18. Estimating Depreciation Due to PPP. Assume that the spot exchange rate of the Britishpound is $1.73. How will this spot rate adjust according to PPP if the United Kingdom experiences an inflation rate of 7 percent while the United States experiences an inflation rate of 2 percent?ANSWER: According to PPP, the exchange rate of the pound will depreciate by 4.7 percent.Therefore, the spot rate would adjust to $1.73 × [1 + (–.047)] = $1.65.19. Forecasting the Future Spot Rate Based on IFE. Assume that the spot exchange rate of theSingapore dollar is £0.35. The one-year interest rate is 11 percent in the United Kingdom and7 percent in Singapore. What will the spot rate be in one year according to the IFE? (Youmay use the approximate formula to answer this question.)ANSWER: £0.35 × (1 + .04) = £0.36420. Deriving Forecasts of the Future Spot Rate. As of today, assume the following informationis available:UK MexicoReal rate of interest requiredinvestors 2% 2%byNominal interest rate 11% 15%Spot rate — £0.05One-year forward rate — £0.049a. Use the forward rate to forecast the percentage change in the Mexican peso over the nextyear.ANSWER: (£0.049– £0.05)/£0.05 = –.02, or –2%b. Use the differential in expected inflation to forecast the percentage change in theMexican peso over the next year.ANSWER: 11% – 15% = –4%; the negative sign represents depreciation of the peso.c. Use the spot rate to forecast the percentage change in the Mexican peso over the next year.ANSWER: zero percent change21. Inflation and Interest Rate Effects. The opening of Russia's market has resulted in a highlyvolatile Russian currency (the rouble). Russia's inflation has commonly exceeded 20 percent per month. Russian interest rates commonly exceed 150 percent, but this is sometimes less than the annual inflation rate in Russia.a. Explain why the high Russian inflation has put severe pressure on the value of theRussian rouble.ANSWER: As Russian prices were increasing, the purchasing power of Russian consumers was declining. This would encourage them to purchase goods in the UK and elsewhere, which results in a large supply of roubles for sale. Given the high Russian inflation, foreign demand for roubles to purchase Russian goods would be low. Thus, the rouble’s value should depreciate against the dollar, and against other currencies.b. Does the effect of Russian inflation on the decline in the rouble’s value support the PPPtheory? How might the relationship be distorted by political conditions in Russia?ANSWER: The general relationship suggested by PPP is supported, but the rouble’s value will not normally move exactly as specified by PPP. The political conditions that could restrict trade or currency convertibility can prevent Russian consumers from shifting to foreign goods. Thus, the rouble may not decline by the full degree to offset the inflation differential between Russia and the UK Furthermore, the government may not allow the rouble to float freely to its proper equilibrium level.c. Does it appear that the prices of Russian goods will be equal to the prices of UK goodsfrom the perspective of Russian consumers (after considering exchange rates)? Explain.ANSWER: Russian prices might be higher than UK prices, even after considering exchange rates, because the rouble might not depreciate enough to fully offset the Russian inflation. The exchange rate cannot fully adjust if there are barriers on trade or currency convertibility.d. Will the effects of the high Russian inflation and the decline in the rouble offset eachother for UK importers? That is, how will UK importers of Russian goods be affected by the conditions?ANSWER: UK importers will likely experience higher prices, because the Russian inflation may not be completely offset by the decline in the rouble’s value. This may cause a reduction in the UK demand for Russian goods.22. IFE Application to Asian Crisis. Before the Asian crisis, many investors attempted tocapitalize on the high interest rates prevailing in the Southeast Asian countries although the level of interest rates primarily reflected expectations of inflation. Explain why investors behaved in this manner.Why does the IFE suggest that the Southeast Asian countries would not have attracted foreign investment before the Asian crisis despite the high interest rates prevailing in those countries?ANSWER: The investors' behavior suggests that they did not expect the international Fisher effect (IFE) to hold. Since central banks of some Asian countries were maintaining their currencies within narrow bands, they were effectively preventing the exchange rate from depreciating in a manner that would offset the interest rate differential. Consequently, superior profits from investing in the foreign countries were possible.If investors believed in the IFE, the Asian countries would not attract a high level of foreign investment because of exchange rate expectations. Specifically, the high nominal interest rate should reflect a high level of expected inflation. According to purchasing power parity (PPP), the higher interest rate should result in a weaker currency because of the implied market expectations of high inflation.23. IFE Applied to the Euro. Given the recent conversion of several European currencies to theeuro, explain what would cause the euro’s value to change against the dollar according to the IFE.ANSWER: If interest rates change in these European countries whose home currency is the euro, the expected inflation rate in those countries change, so that the inflation differential between those countries and the U.S. changes. Thus, there may be an impact on the value of the euro, because a change in the inflation differential affects trade flows and therefore affects the exchange rate.Advanced Questions24. IFE. Beth Miller does not believe that the international Fisher effect (IFE) holds. Currentone-year interest rates in Europe are 5 percent, while one-year interest rates in the U.S. are 3 percent. Beth converts $100,000 to euros and invests them in Germany. One year later, she converts the euros back to dollars. The current spot rate of the euro is $1.10.a. According to the IFE, what should the spot rate of the euro in one year be?b. If the spot rate of the euro in one year is $1.00, what is Beth’s percentage return from herstrategy?c. If the spot rate of the euro in one year is $1.08, what is Beth’s percentage return from herstrategy?d. What must the spot rate of the euro be in one year for Beth’s strategy to be successful?ANSWER:a.%90.11)05.1()03.1(1)1()1(−=−=−++=f h f i i eIf the IFE holds, the euro should depreciate by 1.90 percent in one year. This translates to a spot rate of $1.10 × (1 – 1.90%) = $1.079.b.1. Convert dollars to euros: $100,000/$1.10 = €90,909.092. Invest euros for one year and receive €90,909.09 × 1.05 = €95,454.553. Convert euros back to dollars and receive €95,454.55 × $1.00 = $95,454.55The percentage return is $95,454.55/$100,000 – 1 = –4.55%.c.1. Convert dollars to euros: $100,000/$1.10 = €90,909.092. Invest euros for one year and receive €90,909.09 × 1.05 = €95,454.553. Convert euros back to dollars and receive €95,454.55 × $1.08 = $103,090.91The percentage return is $103,090.91/$100,000 – 1 = 3.09%.d. Beth’s strategy would be successful if the spot rate of the euro in one year is greater than$1.079.25. Integrating IRP and IFE. Assume the following information is available for the U.S. andEurope:U.S. Europe Nominal interest rate 4% 6%Expected inflation 2% 5%Spot rate ----- $1.13One-year forward rate ----- $1.10a. Does IRP hold?b. According to PPP, what is the expected spot rate of the euro in one year?c. According to the IFE, what is the expected spot rate of the euro in one year?d. Reconcile your answers to parts (a). and (c).ANSWER:a.%89.11)06.1()04.1(1)1()1(−=−=−++=f h i i pTherefore, the forward rate of the euro should be $1.13 × (1 – 1.89%) = $1.109.

IRP. The one-year risk-free interest rate in Mexico is 10%. The one-year risk-free rate in theUK is 2%. Assume that interest rate parity exists. The spot rate of the Mexican peso is £0.14.a. What is the forward rate premium?b. What is the one-year forward rate of the peso?c. Based on the international Fisher effect, what is the expected change in the spot rate over thenext year?d.If the spot rate changes as expected according to the IFE, what will be the spot rate in oneyear?pare your answers to (b) and (d) and explain the relationship.ANSWER:a. According to interest rate parity, the forward premium is07273.1)10.1()02.1(−=−++b. The forward rate is £0.14 × (1 – .07273) = £0.1298.c.

When IRP holds, the forward rate premium and the expected percentage change in the spot rate are derived in the same manner. Thus, the forward premium serves as the forecasted percentage change in the spot rate according to IFE.27. Testing the PPP. How could you use regression analysis to determine whether therelationship specified by PPP exists on average? Specify the model, and describe how you would assess the regression results to determine if there is a significant difference from the relationship suggested by PPP.ANSWER: A regression model could be applied to historical data to test PPP. The model isspecified as:()e a a 1+I 1 + I u f 01U.S.f =+−⎡⎣⎢⎤⎦⎥+1where e f is the percentage change in the foreign currency’s exchange rate, I U.S. and I f are U.S.and foreign inflation rates, a 0 is a constant, a 1 is the slope coefficient, and u is an error term.

国际财务管理答案CHAPTER8
国际财务管理答案CHAPTER8CHAPTER 8QUESTION1.你会如何定义交易风险暴露？它与经济风险暴露有什么不同？Answer：交易风险暴露是在交易结算时，国内公司合同中的资金流动的货币价值是以外币标价，由于外汇汇率变化而引起的风险。
（我来打个比方：其实就是以外币计值的交易，折合成本币价值时的不确定性而带来的风险）。
不同于经济风险暴露，交易暴露更加定义明确并且是短期的。
2. 讨论并比较使用远期合约与使用货币市场工具对交易风险暴露的套期保值。
在何种情况下两者效果相同？A：使用远期合约对交易风险暴露进行套期保值是通过购买或者卖出外币的应收款或者应付款。
另一方面，货币市场工具的套期保值是通过借入或者外租当期市场价值的外币然后抵补应付账款或应收账款（书上的原文太难用中文解释了，我打个比方：货币市场套期保值的内容包括利用不同货币的利率之差进行保值和进行货币互换。
例如公司可以借入一种货币A，然后换成另外一种货币B进行投资，债务到期后，再兑换成原借入的货币A还款）。
假如利率平价是存在的话，那么这两种套期保值方法的效果是相同的。
3.讨论并比较通过远期合约与期权合约进行套期保值的成本。
A：并不能预先知道通过远期合约进行套期保值的成本。
然而，在期权合约进行套期保值的情况下，要进行套期保值必须为合同预先支付额外费用。
远期合约套期保值的费用可能在他们后悔做了远期合约保值的决定的之前就被知道。
4.作为一种套期保值的工具，货币期权合约与远期合约相比有哪些优点？A：使用期权合约的主要优势是能让进行套期保值的人当他们留意和意识到未来利率变化的时候，能够决定是否运用期权合约进行套期保值。
如此一来，期权合约就提供了套期保值，在使用远期合约收到损失让你后悔之前。
进行套期保值的人就能在保持潜在的积极因素下避免了消极的风险。
5.假设你们公司购买欧元看跌期权来管理一项与该外币应收款相关的外汇风险暴露。
在这种情况下，可以说你们公司对这个应收款进行了保险。

国际财务管理(英文版)课后习题答案9
CHAPTER 8 MANAGEMENT OF TRANSACTION EXPOSURE SUGGESTED ANSWERS AND SOLUTIONS TO END-OF-CHAPTER QUESTIONS AND PROBLEMSQUESTIONS1. How would you define transaction exposure? How is it different from economic exposure?Answer: Transaction exposure is the sensitivity of realized domestic currency values of the firm’s contractual cash flows denominated in foreign currencies to unexpected changes in exchange rates. Unlike economic exposure, transaction exposure is well-defined and short-term.2. Discuss and compare hedging transaction exposure using the forward contract vs. money market instruments. When do the alternative hedging approaches produce the same result?Answer: Hedging transaction exposure by a forward contract is achieved by selling or buying foreign currency receivables or payables forward. On the other hand, money market hedge is achieved by borrowing or lending the present value of foreign currency receivables or payables, thereby creating offsetting foreign currency positions. If the interest rate parity is holding, the two hedging methods are equivalent.3. Discuss and compare the costs of hedging via the forward contract and the options contract.Answer: There is no up-front cost of hedging by forward contracts. In the case of options hedging, however, hedgers should pay the premiums for the contracts up-front. The cost of forward hedging, however, may be realized ex post when the hedger regrets his/her hedging decision.4. What are the advantages of a currency options contract as a hedging tool compared with the forward contract?Answer: The main advantage of using options contracts for hedging is that the hedger can decide whether to exercise options upon observing the realized future exchange rate. Options thus provide a hedge against ex post regret that forward hedger might have to suffer. Hedgers can only eliminate the downside risk while retaining the upside potential.5. Suppose your company has purchased a put option on the German mark to manage exchange exposure associated with an account receivable denominated in that currency. In this case, your company can be said to have an ‘insurance’ policy on its receivable. Explain in what sense this is so.Answer: Your company in this case knows in advance that it will receive a certain minimum dollar amount no matter what might happen to the $/€ exchange rate. Furthermore, if the German mark appreciates, your company will benefit from the rising euro.6. Recent surveys of corporate exchange risk management practices indicate that many U.S. firms simply do not hedge. How would you explain this result?Answer: There can be many possible reasons for this. First, many firms may feel that they are not really exposed to exchange risk due to product diversification, diversified markets for their products, etc. Second, firms may be using self-insurance against exchange risk. Third, firms may feel that shareholders can diversify exchange risk themselves, rendering corporate risk management unnecessary.7. Should a firm hedge? Why or why not?Answer: In a perfect capital market, firms may not need to hedge exchange risk. But firms can add to their value by hedging if markets are imperfect. First, if management knows about the firm’s exposure better than shareholders, the firm, not it s shareholders, should hedge. Second, firms may be able to hedge at a lower cost. Third, if default costs are significant, corporate hedging can be justifiable because it reduces the probability ofdefault. Fourth, if the firm faces progressive taxes, it can reduce tax obligations by hedging which stabilizes corporate earnings.8. Using an example, discuss the possible effect of hedging on a firm’s tax obligations.Answer: One can use an example similar to the one presented in the chapter.9. Explain contingent exposure and discuss the advantages of using currency options to manage this type of currency exposure.Answer: Companies may encounter a situation where they may or may not face currency exposure. In this situation, companies need options, not obligations, to buy or sell a given amount of foreign exchange they may or may not receive or have to pay. If companies either hedge using forward contracts or do not hedge at all, they may face definite currency exposure.10. Explain cross-hedging and discuss the factors determining its effectiveness.Answer: Cross-hedging involves hedging a position in one asset by taking a position in another asset. The effectiveness of cross-hedging would depend on the strength and stability of the relationship between the two assets.PROBLEMS1. Cray Research sold a super computer to the Max Planck Institute in Germany on credit and invoiced €10 million payable in six months. Currently, the six-month forward exchange rate is $1.10/€ and the foreign exchange advisor for Cray Research predicts that the spot rate is likely to be $1.05/€ in six months.(a) What is the expected gain/loss from the forward hedging?(b) If you were the financial manager of Cray Research, would you recommend hedging this euro receivable? Why or why not?(c) Suppose the foreign exchange advisor predicts that the future spot rate will be the same as the forward exchange rate quoted today. Would you recommend hedging in this case? Why or why not?Solution: (a) Expected gain($) = 10,000,000(1.10 – 1.05)= 10,000,000(.05)= $500,000.(b) I would recommend hedging because Cray Research can increase the expected dollar receipt by $500,000 and also eliminate the exchange risk.(c) Since I eliminate risk without sacrificing dollar receipt, I still would recommend hedging.2. IBM purchased computer chips from NEC, a Japanese electronics concern, and was billed ¥250 million payable in three months. Currently, the spot exchange rate is ¥105/$ and the three-month forward rate is ¥100/$. The three-month money market interest rate is 8 percent per annum in the U.S. and 7 percent per annum in Japan. The management of IBM decided to use the money market hedge to deal with this yen account payable.(a) Explain the process of a money market hedge and compute the dollar cost of meeting the yen obligation.(b) Conduct the cash flow analysis of the money market hedge.Solution: (a). Let’s first compute the PV of ¥250 million, i.e.,250m/1.0175 = ¥245,700,245.7So if the above yen amount is invested today at the Japanese interest rate for three months, the maturity value will be exactly equal to ¥25 million which is the amount of payable. To buy the above yen amount today, it will cost:$2,340,002.34 = ¥250,000,000/105.The dollar cost of meeting this yen obligation is $2,340,002.34 as of today.(b)___________________________________________________________________Transaction CF0 CF1____________________________________________________________________1.

You plan to visit Geneva, Switzerland in three months to attend an international business conference. You expect to incur the total cost of SF 5,000 for lodging, meals and transportation during your stay. As of today, the spot exchange rate is $0.60/SF and the three-month forward rate is $0.63/SF. You can buy the three-month call option on SF with the exercise rate of $0.64/SF for the premium of $0.05 per SF. Assume that your expected future spot exchange rate is the same as the forward rate. The three-month interest rate is 6 percent per annum in the United States and 4 percent per annum in Switzerland. (a) Calculate your expected dollar cost of buying SF5,000 if you choose to hedge via call option on SF.(b) Calculate the future dollar cost of meeting this SF obligation if you decide to hedge using a forward contract.(c) At what future spot exchange rate will you be indifferent between the forward and option market hedges?(d) Illustrate the future dollar costs of meeting the SF payable against the future spot exchange rate under both the options and forward market hedges.Solution: (a) Total option premium = (.05)(5000) = $250. In three months, $250 is worth $253.75 = $250(1.015). At the expected future spot rate of $0.63/SF, which is less than the exercise price, you don’t expect to exercise options. Rather, you expect to buy Swiss franc at $0.63/SF. Since you are going to buy SF5,000, you expect to spend $3,150 (=.63x5,000). Thus, the total expected cost of buying SF5,000 will be the sum of $3,150 and $253.75, i.e., $3,403.75.(b) $3,150 = (.63)(5,000).(c) $3,150 = 5,000x + 253.75, where x represents the break-even future spot rate. Solving for x, we obtain x = $0.57925/SF. Note that at the break-even future spot rate, options will not be exercised.(d) If the Swiss franc appreciates beyond $0.64/SF, which is the exercise price of call option, you will exercise the option and buy SF5,000 for $3,200. The total cost of buying SF5,000 will be $3,453.75 = $3,200 + $253.75.This is the maximum you will pay.4. Boeing just signed a contract to sell a Boeing 737 aircraft to Air France. Air France will be billed €20 million which is payable in one year. The current spot exchange rate is $1.05/€ and the one -year forward rate is $1.10/€. The annual interest rat e is 6.0% in the U.S. and5.0% in France. Boeing is concerned with the volatile exchange rate between the dollar and the euro and would like to hedge exchange exposure.(a) It is considering two hedging alternatives: sell the euro proceeds from the sale forward or borrow euros from the Credit Lyonnaise against the euro receivable. Which alternative would you recommend? Why?(b) Other things being equal, at what forward exchange rate would Boeing be indifferent between the two hedging methods?Solution: (a) In the case of forward hedge, the future dollar proceeds will be (20,000,000)(1.10) = $22,000,000. In the case of money market hedge (MMH), the firm has to first borrow the PV of its euro receivable, i.e., 20,000,000/1.05 =€19,047,619. Then the firm should exchange this euro amount into dollars at the current spot rate to receive: (€19,047,619)($1.05/€) = $20,000,000, which can be invested at the dollar interest rate $ Cost Options hedge Forward hedge $3,453.75 $3,150 0 0.579 0.64 (strike price) $/SF$253.75for one year to yield:$20,000,000(1.06) = $21,200,000.Clearly, the firm can receive $800,000 more by using forward hedging.(b) According to IRP, F = S(1+i$)/(1+i F). Thus the “indifferent” forward rate will be:F = 1.05(1.06)/1.05 = $1.06/€.5. Suppose that Baltimore Machinery sold a drilling machine to a Swiss firm and gave the Swiss client a choice of paying either $10,000 or SF 15,000 in three months.(a) In the above example, Baltimore Machinery effectively gave the Swiss client a free option to buy up to $10,000 dollars using Swiss franc. What is the ‘implied’ exercise exchange rate?(b) If the spot exchange rate turns out to be $0.62/SF, which currency do you think the Swiss client will choose to use for payment? What is the value of this free option for the Swiss client?(c) What is the best way for Baltimore Machinery to deal with the exchange exposure?Solution: (a) The implied exercise (price) rate is: 10,000/15,000 = $0.6667/SF.(b) If the Swiss client chooses to pay $10,000, it will cost SF16,129 (=10,000/.62). Since the Swiss client has an option to pay SF15,000, it will choose to do so. The value of this option is obviously SF1,129 (=SF16,129-SF15,000).(c) Baltimore Machinery faces a contingent exposure in the sense that it may or may not receive SF15,000 in the future. The firm thus can hedge this exposure by buying a put option on SF15,000.6. Princess Cruise Company (PCC) purchased a ship from Mitsubishi Heavy Industry. PCC owes Mitsubishi Heavy Industry 500 million yen in one year. The current spot rate is 124 yen per dollar and the one-year forward rate is 110 yen per dollar. The annual interest rate is 5% in Japan and 8% in the U.S. PCC can also buy a one-year call option on yen at the strike price of $.0081 per yen for a premium of .014 cents per yen.(a) Compute the future dollar costs of meeting this obligation using the money market hedgeand the forward hedges.(b) Assuming that the forward exchange rate is the best predictor of the future spot rate, compute the expected future dollar cost of meeting this obligation when the option hedge is used.(c) At what future spot rate do you think PCC may be indifferent between the option and forward hedge?Solution: (a) In the case of forward hedge, the dollar cost will be 500,000,000/110 = $4,545,455. In the case of money market hedge, the future dollar cost will be: 500,000,000(1.08)/(1.05)(124)= $4,147,465.(b) The option premium is: (.014/100)(500,000,000) = $70,000. Its future value will be $70,000(1.08) = $75,600.At the expected future spot rate of $.0091(=1/110), which is higher than the exercise of $.0081, PCC will exercise its call option and buy ¥500,000,000 for $4,050,000 (=500,000,000x.0081).The total expected cost will thus be $4,125,600, which is the sum of $75,600 and $4,050,000.(c) When the option hedge is used, PCC will spend “at most” $4,125,000. On the other hand, when the forward hedging is used, PCC will have to spend $4,545,455 regardless of the future spot rate. This means that the options hedge dominates the forward hedge. At no future spot rate, PCC will be indifferent between forward and options hedges.7. Airbus sold an aircraft, A400, to Delta Airlines, a U.S. company, and billed $30 million payable in six months. Airbus is concerned with the euro proceeds from international sales and would like to control exchange risk. The current spot exchange rate is $1.05/€ and six-month forward exchange rate is $1.10/€ at the moment. Airbus can buy a six-month put option on U.S. dollars with a strike price of €0.95/$ for a premium of €0.02 per U.S. dollar. Currently, six-month interest rate is 2.5% in the euro zone and 3.0% in the U.S.pute the guaranteed euro proceeds from the American sale if Airbus decides to hedgeusing a forward contract.b.If Airbus decides to hedge using money market instruments, what action does Airbusneed to take? What would be the guaranteed euro proceeds from the American sale in this case?c.If Airbus decides to hedge using put options on U.S. dollars, what would be the‘expected’ euro proceeds from the American sale? Assume that Airbus regards the current forward exchange rate as an unbiased predictor of the future spot exchange rate.d.At what future spot exchange rate do you think Airbus will be indifferent between theoption and money market hedge?Solution:a. Airbus will sell $30 million forward for €27,272,727 = ($30,000,000) / ($1.10/€).b. Airbus will borrow the present value of the dollar receivable, i.e., $29,126,214 = $30,000,000/1.03, and then sell the dollar proceeds spot for euros: €27,739,251. This is the euro amount that Airbus is going to keep.c. Since the expected future spot rate is less than the strike price of the put option, i.e., €0.9091< €0.95, Airbus expects to exercise the option and receive €28,500,000 = ($30,000,000)(€0.95/$). This is gross proceeds. Airbus spent €600,000 (=0.02x30,000,000) upfront for the option and its future cost is equal to €615,000 = €600,000 x 1.025. Thus the net euro proceeds from the American sale is €27,885,000, which is the difference between the gross proceeds and the option costs.d. At the indifferent future spot rate, the following will hold:€28,432,732 = S T (30,000,000) - €615,000.Solving for S T, we obtain the “indifference” future spot exchange rate, i.e., €0.9683/$, or $1.0327/€. Note that €28,432,732 is the future value of the proceed s under money market hedging:€28,432,732 = (€27,739,251) (1.025).Suggested solution for Mini Case: Chase Options, Inc.[See Chapter 13 for the case text]Chase Options, Inc.Hedging Foreign Currency Exposure Through Currency OptionsHarvey A. PoniachekI. Case SummaryThis case reviews the foreign exchange options market and hedging. It presents various international transactions that require currency options hedging strategies by the corporations involved. Seven transactions under a variety of circumstances are introduced that require hedging by currency options. The transactions involve hedging of dividend remittances, portfolio investment exposure, and strategic economic competitiveness. Market quotations are provided for options (and options hedging ratios), forwards, and interest rates for various maturities.II. Case Objective.The case introduces the student to the principles of currency options market and hedging strategies. The transactions are of various types that often confront companies that are involved in extensive international business or multinational corporations. The case induces students to acquire hands-on experience in addressing specific exposure and hedging concerns, including how to apply various market quotations, which hedging strategy is most suitable, and how to address exposure in foreign currency through cross hedging policies.III. Proposed Assignment Solution1. The company expects DM100 million in repatriated profits, and does not want the DM/$ exchange rate at which they convert those profits to rise above 1.70. They can hedge this exposure using DM put options with a strike price of 1.70. If the spot rate rises above 1.70, they can exercise the option, while if that rate falls they can enjoy additionalprofits from favorable exchange rate movements.To purchase the options would require an up-front premium of:DM 100,000,000 x 0.0164 = DM 1,640,000.With a strike price of 1.70 DM/$, this would assure the U.S. company of receiving at least:DM 100,000,000 – DM 1,640,000 x (1 + 0.085106 x 272/360)= DM 98,254,544/1.70 DM/$ = $57,796,791by exercising the option if the DM depreciated. Note that the proceeds from the repatriated profits are reduced by the premium paid, which is further adjusted by the interest foregone on this amount.However, if the DM were to appreciate relative to the dollar, the company would allow the option to expire, and enjoy greater dollar proceeds from this increase.Should forward contracts be used to hedge this exposure, the proceeds received would be: DM100,000,000/1.6725 DM/$ = $59,790,732,regardless of the movement of the DM/$ exchange rate. While this amount is almost $2 million more than that realized using option hedges above, there is no flexibility regarding the exercise date; if this date differs from that at which the repatriate profits are available, the company may be exposed to additional further current exposure. Further, there is no opportunity to enjoy any appreciation in the DM.If the company were to buy DM puts as above, and sell an equivalent amount in calls with strike price 1.647, the premium paid would be exactly offset by the premium received. This would assure that the exchange rate realized would fall between 1.647 and 1.700. If the rate rises above 1.700, the company will exercise its put option, and if it fell below 1.647, the other party would use its call; for any rate in between, both options wouldexpire worthless. The proceeds realized would then fall between:DM 100,00,000/1.647 DM/$ = $60,716,454andDM 100,000,000/1.700 DM/$ = $58,823,529.This would allow the company some upside potential, while guaranteeing proceeds at least $1 million greater than the minimum for simply buying a put as above.Buy/Sell OptionsDM/$Spot Put Payoff “Put”ProfitsCallPayoff“Call”Profits Net Profit1.60(1,742,846)01,742,84660,716,45460,716,4541.61(1,742,846)01,742,84660,716,45460,716,4541.62(1,742,846)01,742,84660,716,45460,716,454 1.63(1,742,846)01,742,84660,716,45460,716,4541.64(1,742,846)01,742,84660,716,45460,716,4541.65(1,742,846)60,606,0611,742,846060,606,061 1.66(1,742,846)60,240,9641,742,846060,240,9641.67(1,742,846)59,880,241,742,846059,880,240 1.68(1,742,846)59,523,811,742,846059,523,8101.69(1,742,846)59,171,591,742,846059,171,59881,742,846058,823,529 1.70(1,742,846)58,823,5291.71(1,742,846)58,823,521,742,846058,823,52991,742,846058,823,529 1.72(1,742,846)58,823,5291.73(1,742,846)58,823,521,742,846058,823,52991.74(1,742,846)58,823,521,742,846058,823,52991.75(1,742,846)58,823,521,742,846058,823,52991,742,846058,823,529 1.76(1,742,846)58,823,5291,742,846058,823,529 1.77(1,742,846)58,823,5291,742,846058,823,529 1.78(1,742,846)58,823,5291,742,846058,823,529 1.79(1,742,846)58,823,5291,742,846058,823,529 1.80(1,742,846)58,823,5291,742,846058,823,529 1.81(1,742,846)58,823,5291.82(1,742,846)58,823,521,742,846058,823,52991.83(1,742,846)58,823,521,742,846058,823,5291.84(1,742,846)58,823,521,742,846058,823,52991,742,846058,823,529 1.85(1,742,846)58,823,529Since the firm believes that there is a good chance that the pound sterling will weaken, locking them into a forward contract would not be appropriate, because they would lose the opportunity to profit from this weakening. Their hedge strategy should follow for an upside potential to match their viewpoint. Therefore, they should purchase sterling call options, paying a premium of:5,000,000 STG x 0.0176 = 88,000 STG.If the dollar strengthens against the pound, the firm allows the option to expire, and buys sterling in the spot market at a cheaper price than they would have paid for a forward contract; otherwise, the sterling calls protect against unfavorable depreciation of the dollar.Because the fund manager is uncertain when he will sell the bonds, he requires a hedge which will allow flexibility as to the exercise date. Thus, options are the best instrument for him to use. He can buy A$ puts to lock in a floor of 0.72 A$/$. Since he is willing to forego any further currency appreciation, he can sell A$ calls with a strike price of 0.8025 A$/$ to defray the cost of his hedge (in fact he earns a net premium of A$ 100,000,000 x (0.007234 –0.007211) = A$ 2,300), while knowing that he can’t receive less than 0.72 A$/$ when redeeming his investment, and can benefit from a small appreciation of the A$.Example #3:Problem: Hedge principal denominated in A$ into US$.

The German company is bidding on a contract which they cannot be certain of winning. Thus, the need to execute a currency transaction is similarly uncertain, and using a forward or futures as a hedge is inappropriate, because it would force them to perform even if they do not win the contract.Using a sterling put option as a hedge for this transaction makes the most sense. For a premium of:12 million STG x 0.0161 = 193,200 STG,they can assure themselves that adverse movements in the pound sterling exchange rate will not diminish the profitability of the project (and hence the feasibility of their bid),while at the same time allowing the potential for gains from sterling appreciation.5. Since AMC in concerned about the adverse effects that a strengthening of the dollar would have on its business, we need to create a situation in which it will profit from such an appreciation. Purchasing a yen put or a dollar call will achieve this objective. The data in Exhibit 1, row 7 represent a 10 percent appreciation of the dollar (128.15 strike vs. 116.5 forward rate) and can be used to hedge against a similar appreciation of the dollar.For every million yen of hedging, the cost would be:Yen 100,000,000 x 0.000127 = 127 Yen.To determine the breakeven point, we need to compute the value of this option if the dollar appreciated 10 percent (spot rose to 128.15), and subtract from it the premium we paid. This profit would be compared w ith the profit earned on five to 10 percent of AMC’s sales (which would be lost as a result of the dollar appreciation). The number of options to be purchased which would equalize these two quantities would represent the breakeven point.Example #5:Hedge the economic cost of the depreciating Yen to AMC.If we assume that AMC sales fall in direct proportion to depreciation in the yen (i.e., a 10 percent decline in yen and 10 percent decline in sales), then we can hedge the full value of AMC’s sales. I hav e assumed $100 million in sales.1) Buy yen puts# contracts needed = Expected Sales *Current ¥/$ Rate / Contract size9600 = ($100,000,000)(120¥/$) / ¥1,250,0002) Total Cost = (# contracts)(contract size)(premium)$1,524,000 = (9600)( ¥1,250,000)($0.0001275/¥)3) Floor rate = Exercise – Premium128.1499¥/$ = 128.15¥/$ - $1,524,000/12,000,000,000¥4) The payoff changes depending on the level of the ¥/$ rate.

Answer: The The forward forward forward market market market is is is an an an OTC OTC OTC market market market where where where the the the forward forward forward contract contract contract for for for purchase purchase purchase or or or sale sale sale of of foreign currency is tailor-made between the client and its international bank. No money changes hands until the maturity date of the contract when delivery and receipt are typically made. A futures contract is an an exchange-traded exchange-traded exchange-traded instrument instrument instrument with with with standardized standardized standardized features features features specifying specifying specifying contract contract contract size size size and and and delivery delivery delivery date. date.

Delivery Delivery is is seldom made in a futures market. Rather a reversing trade is made to close out a long or short position.2. In In order order order for for for a a a derivatives derivatives derivatives market market market to to to function function function most most most efficiently, efficiently, two two types types types of of of economic economic economic agents agents agents are are needed: hedgers and speculators. Explain. Answer: Two Two types types types of of of market market market participants participants participants are are are necessary necessary necessary for for for the the the efficient efficient efficient operation operation operation of of of a a a derivatives derivatives market: speculators and h edgers hedgers . A speculator attempts to profit from a change in the futures price. To To do do do this, this, this, the the the speculator speculator speculator will will will take take take a a a long long long or or or short short short position position position in in in a a a futures futures futures contract contract contract depending depending depending upon upon upon his his expectations of future price movement. A hedger, on-the-other-hand, desires to avoid price variation by locking in a purchase price of the underlying asset through a long position in a futures contract or a sales price through a short position. In effect, the hedger passes off the risk of price variation to the speculator who is better able, or at least more willing, to bear this risk. 3. Why are most futures positions closed out through a reversing trade rather than held to delivery? Answer: In forward markets, approximately 90 percent of all contracts that are initially established result i n the short making delivery to the long of the asset underlying the contract. This is natural because the terms of forward forward contracts contracts contracts are are are tailor-made tailor-made between the the long long long and and and short. short. By By contrast, contrast, only only about about about one one one percent percent percent of of currency futures contracts result in delivery. While futures contracts are useful for speculation and hedgi n g , their standardized delivery delivery dates dates dates make them make them unlikely unlikely to to to correspond correspond correspond to the actual future to the actual future dates when foreign IM-2 exchange exchange transactions transactions transactions will will will occur. occur.

How can the FX futures market be used for price discovery? Answer: To the extent that FX forward prices are an unbiased predictor of future spot exchange rates, the market anticipates whether one currency will appreciate or depreciate versus another. Because FXfutures contracts trade in an expiration cycle, different contracts expire at different periodic dates into the future. The pattern of the prices of these cont racts provides information as to the market’s current belief about about the the the relative relative relative future future future value value value of of of one one one currency currency currency versus versus versus another at another at the the scheduled scheduled scheduled expiration expiration expiration dates dates dates of of of the the contracts.

Thus, Thus, the the the futures futures futures market market market is is is useful useful useful for for price discovery , , i.e., i.e., i.e., obtaining obtaining obtaining the the the market’s market’s forecast of the spot exchange rate at different future dates. 5. What is the major difference in the obligation of one with a long position in a futures (or forward) contract in comparison to an options contract? Answer: Answer: A A A futures futures futures (or (or (or forward) forward) forward) contract contract contract is is is a a a vehicle vehicle vehicle for for for buying buying buying or or or selling selling selling a a a stated stated stated amount amount amount of of of foreign foreign exchange at a stated price per unit at a specified time in the future.

By By contrast, contrast, contrast, an an an option option option is is is a a contract giving the long the right to buy or sell a given quantity of an asset at a specified price at some time time in in in the the the future, future, future, but but but not enforcing not enforcing any any obligation obligation obligation on on on him him him if if if the the the spot spot spot price price price is is is more more more favorable favorable favorable than than than the the exercise price. Because the option owner does not have to exercise the option if it is to his disadvantage, the option has a price, or premium, whereas no price is paid at inception to enter into a futures (or forward) contract. 6. What is meant by the terminology that an option is in-, at-, or out-of-the-money? Answer: A call (put) option with S t > E (E > S t ) is referred to as trading in-the-money. If S t@ E the option is trading at-the-money. If S t< E (E < S t ) the call (put) option is trading out-of-the-money . IM-3 7. List List the the the arguments (variables) arguments (variables) of of which which which an an an FX call FX call or or put put put option option option model model model price price price is is is a function. a function. How does the call and put premium change with respect to a change in the arguments? Answer: Both call and put options are functions of only six variables: S t , E, r i , r $, Ta nd and s . When all else remains the same, the price of a European FX call (put) option will increase: 1. the larger (smaller) is S , 2. the smaller (larger) is E , 3. the smaller (larger) is r i , 4. the larger (smaller) is r $, 5. the larger (smaller) r $ is relative to r i , and 6. the greater is s . When r $ and r i are not too much different in size, a European FX call and put will increase in price when the option term-to-maturity increases. However, when r $ is very much larger than r i , a European FX call will will increase increase increase in in in price, price, price, but but but the the the put put put premium premium premium will will will decrease, decrease, decrease, when when when the the the option option option term-to-maturity term-to-maturity term-to-maturity increases. increases. The opposite is true when r i is very much greater than r $. For American FX options the analysis is less complicated. Since Since a a a longer longer longer term term term American American American option option option can can can be be be exercised exercised exercised on on on any any any date date date that that that a shorter a shorter term option can be exercised, or a some later date, it follows that the all else remaining the same, the longer term American option will sell at a price at least as large as the shorter term option.

Describe the strip hedge that Johnson could use and explain how it hedges the 12-month loan (specify number of contracts). No calculations are needed. CFA Guideline Answer a. The basis point value (BPV) of a Eurodollar futures contract can be found by substituting the contract specifications into the following money market relationship: BPV FUT = Change in V alue = (face value) x (days to maturity / 360) x (change in yield)= ($1 million) x (90 / 360) x (.0001) = $25 The number of contract, N, can be found by: N = (BPV spot) / (BPV futures) = ($2,500) / ($25) = 100 OR IM-7 N = (value of spot position) / (face value of each futures contract) = ($100 million) / ($1 million) = 100 OR N = (value of spot position) / (value of futures position) = ($100,000,000) / ($981,750) where value of futures position = $1,000,000 x [1 – (0.073 / 4)] » 102 contracts Therefore on September 20, Johnson would sell 100 (or 102) December Eurodollar futures contracts at the 7.3 percent yield. The implied LIBOR rate in December is 7.3 percent as indicated by the December Eurofutures discount yield of 7.3 percent. Thus a borrowing rate of 9.3 percent (7.3 percent + 200 basis points) can be locked in if the hedge is correctly implemented. A rise in the rate to 7.8 percent represents a 50 basis point (bp) i ncrease over the implied LIBOR rate. increase over the implied LIBOR rate. For a 50 basis point increase in LIBOR, the cash flow on the short futures position is: = ($25 per basis point per contract) x 50 bp x 100 contracts = $125,000. However, the cash flow on the floating rate liability is: = -0.098 x ($100,000,000 / 4) = - $2,450,000. Combining Combining the the the cash cash cash flow flow flow from from from the the the hedge hedge hedge with with with the the the cash cash cash flow flow flow from from from the the the loan loan loan results results results in in in a a a net net net outflow outflow outflow of of $2,325,000, which translates into an annual rate of 9.3 percent: = ($2,325,000 x 4) / $100,000,000 = 0.093 This is precisely the implied borrowing rate that Johnson locked in on September 20. Regardless of the LIBOR rate on December 20, the net cash outflow will be $2,325,000, which translates into an annualized rate of 9.3 percent. Consequently, the floating rate liability has been converted to a fixed rate liability in the sense that the interest rate uncertainty associated with the March 20 payment (using the December 20 contract) has been removed as of September 20. b. In a strip hedge, Johnson would sell 100 December futures (for the March payment), 100 March futures (for (for the the the June June June payment), payment), payment), and and and 100 100 100 June futures (for June futures (for t he the the September September September payment). payment). The The objective objective objective is is is to to to hedge hedge each each interest interest interest rate rate rate payment payment payment separately separately separately using using using the the the appropriate appropriate appropriate number number number of of of contracts. contracts. The The problem problem problem is is is the the same as in Part A except here three cash flows are subject to rising rates and a strip of futures is used to Strategy A Strategy BContract Month (contracts) (contracts)September 1998 300 100 December 1998 0 100 March 1999 0 100 a. Explain why strategy B is a more effective hedge than strategy A when the yield curve IM-9 a. Strategy B’s SuperiorityStrategy B is a strip hedge that is constructed by selling (shorting) 100 futures contracts maturing in each of of the the the next next next three three three quarters. quarters. With With the the the strip strip strip hedge hedge hedge in in in place, place, place, each each each quarter quarter quarter of of of the the the coming coming coming year year year is is is hedged hedged against shifts in interest rates for that quarter. The reason Strategy B will be a more effective hedge than Strategy Strategy A A A for for for Jacob Jacob Jacob Bower Bower Bower is is is that that that Strategy Strategy Strategy B B B is is is likely likely likely to to to work work work well well well whether whether whether a a a parallel parallel parallel shift shift shift or or or a a nonparallel shift occurs over the one-year term of Bower’s liability. That is, regardless of what happens to the term structure, Strategy B structures the futures hedge so that the rates reflected by the Eurodollar futures cash price match the applicable rates for the underlying liability-the 90day LIBOR-based rate on Bower’s Bower’s liability. liability. The The same same same is is is not not not true true true for for for Strategy Strategy Strategy A. A. Because Because Jacob Jacob Jacob Bower’s Bower’s Bower’s liability liability liability carries carries carries a a floating interest rate that resets quarterly, he needs a strategy that provides a series of three-month hedges. Strategy A will need to be restructured when the three-month September contract expires. In particular, if the yield curve twists upward (futures yields rise more for distant expirations than for near expirations), Strategy A will produce inferior hedge results. b. Scenario in Which Strategy A is Superior Strategy Strategy A A A is is is a a a stack stack stack hedge strategy hedge strategy that that initially initially initially involves involves involves selling selling selling (shorting) (shorting) (shorting) 300 300 300 September September September contracts. contracts.

Only Only from from from the the perspective of favorable cash flows is Strategy A better than Strategy B. Such cash flows occur only in certain certain interest interest interest rate rate rate scenarios. scenarios. For For example example example Strategy Strategy Strategy A A A will will will work work work as as as well well well as as as Strategy Strategy Strategy B B B for for for Bower’s Bower’s liability liability if if if interest interest interest rates rates rates (instantaneously) (instantaneously) (instantaneously) change change change in in in parallel parallel parallel fashion. fashion.

Upon Upon expiration expiration expiration of of of the the September contract, Bower will have to roll out his hedge by selling 200 December contracts to hedge the remaining interest payments. This action will have the effect that the cash flow from Strategy A will be larger than the cash flow from Strategy B because the appreciation on the 300 short September futures contracts will be larger than the cumulative appreciation in the 300 contracts shorted in Strategy B (i.e., 100 100 September, September, September, 100 100 100 December, December, December, and and and 100 100 100 March). March). Consequently, Consequently, the the the cash cash cash flow flow flow from from from Strategy Strategy Strategy A A A will will more than offset the increase in the interest payment on the liability, whereas the cash flow from Strategy B will exactly offset the increase in the interest payment on the liability. 8.

国际财务管理课后习题答案chapter 8
CHAPTER 8 MANAGEMENT OF TRANSACTION EXPOSURE SUGGESTED ANSWERS AND SOLUTIONS TO END-OF-CHAPTER QUESTIONS ANDPROBLEMSQUESTIONS1. How would you define transaction exposure? How is it different from economic exposure?Answer: Transaction exposure is the sensitivity of realized domestic currency values of the firm’s contractual cash flows denominated in foreign currencies to unexpected changes in exchange rates. Unlike economic exposure, transaction exposure is well-defined and short-term.2. Discuss and compare hedging transaction exposure using the forward contract vs. money market instruments. When do the alternative hedging approaches produce the same result?Answer: Hedging transaction exposure by a forward contract is achieved by selling or buying foreign currency receivables or payables forward. On the other hand, money market hedge is achieved by borrowing or lending the present value of foreign currency receivables or payables, thereby creating offsetting foreign currency positions. If the interest rate parity is holding, the two hedging methods are equivalent.3. Discuss and compare the costs of hedging via the forward contract and the options contract.Answer: There is no up-front cost of hedging by forward contracts. In the case of options hedging, however, hedgers should pay the premiums for the contracts up-front. The cost of forward hedging, however, may be realized ex post when the hedger regrets his/her hedging decision.4. What are the advantages of a currency options contract as a hedging tool compared with the forward contract?Answer: The main advantage of using options contracts for hedging is that the hedger can decide whether to exercise options upon observing the realized future exchange rate. Options thus provide ahedge against ex post regret that forward hedger might have to suffer. Hedgers can only eliminate the downside risk while retaining the upside potential.5. Suppose your company has purchased a put option on the German mark to manage exchange exposure associated with an account receivable denominated in that currency. In this case, your company can be said to have an ‘insurance’ policy on its receivable. Explain in what sense this is so.Answer: Your company in this case knows in advance that it will receive a certain minimum dollar amount no matter what might happen to the $/€exchange rate. Furthermore, if the German mark appreciates, your company will benefit from the rising euro.6. Recent surveys of corporate exchange risk management practices indicate that many U.S. firms simply do not hedge. How would you explain this result?Answer: There can be many possible reasons for this. First, many firms may feel that they are not really exposed to exchange risk due to product diversification, diversified markets for their products, etc. Second, firms may be using self-insurance against exchange risk. Third, firms may feel that shareholders can diversify exchange risk themselves, rendering corporate risk management unnecessary.7. Should a firm hedge? Why or why not?Answer: In a perfect capital market, firms may not need to hedge exchange risk. But firms can add to their value by hedging if markets are imperfect. First, if management knows about the firm’s exposure better than shareholders, the firm, not its shareholders, should hedge. Second, firms may be able to hedge at a lower cost. Third, if default costs are significant, corporate hedging can be justifiable because it reduces the probability of default. Fourth, if the firm faces progressive taxes, it can reduce tax obligations by hedging which stabilizes corporate earnings.8. Using an example, discuss the possible effect of hedging on a firm’s tax obligations.Answer: One can use an example similar to the one presented in the chapter.9. Explain contingent exposure and discuss the advantages of using currency options to manage this type of currency exposure.Answer: Companies may encounter a situation where they may or may not face currency exposure. In this situation, companies need options, not obligations, to buy or sell a given amount of foreign exchange they may or may not receive or have to pay. If companies either hedge using forward contracts or do not hedge at all, they may face definite currency exposure.10. Explain cross-hedging and discuss the factors determining its effectiveness.Answer: Cross-hedging involves hedging a position in one asset by taking a position in another asset. The effectiveness of cross-hedging would depend on the strength and stability of the relationship between the two assets.PROBLEMS1. Cray Research sold a super computer to the Max Planck Institute in Germany on credit and invoiced €10 million payable in six months. Currently, the six-month forward exchange rate i s $1.10/€ and the foreign exchange advisor for Cray Research predicts that the spot rate is likely to be $1.05/€ in six months.(a) What is the expected gain/loss from the forward hedging?(b) If you were the financial manager of Cray Research, would you recommend hedging this euro receivable? Why or why not?(c) Suppose the foreign exchange advisor predicts that the future spot rate will be the same as the forward exchange rate quoted today. Would you recommend hedging in this case? Why or why not?Solution: (a) Expected gain($) = 10,000,000(1.10 – 1.05)= 10,000,000(.05)= $500,000.(b) I would recommend hedging because Cray Research can increase the expected dollar receipt by $500,000 and also eliminate the exchange risk.(c) Since I eliminate risk without sacrificing dollar receipt, I still would recommend hedging.2. IBM purchased computer chips from NEC, a Japanese electronics concern, and was billed ¥250 million payable in three months. Currently, the spot exchange rate is ¥105/$ and the three-month forward rate is ¥100/$. The three-month money market interest rate is 8 percent per annum in the U.S. and 7 percent per annum in Japan. The management of IBM decided to use the money market hedge to deal with this yen account payable.(a) Explain the process of a money market hedge and compute the dollar cost of meeting the yen obligation.(b) Conduct the cash flow analysis of the money market hedge.Solution: (a). Let’s first compute the PV of ¥250 million, i.e.,250m/1.0175 = ¥245,700,245.7So if the above yen amount is invested today at the Japanese interest rate for three months, the maturity value will be exactly equal to ¥25 million which is the amount of payable.To buy the above yen amount today, it will cost:$2,340,002.34 = ¥250,000,000/105.The dollar cost of meeting this yen obligation is $2,340,002.34 as of today.(b)___________________________________________________________________Transaction CF0 CF1____________________________________________________________________1.

You plan to visit Geneva, Switzerland in three months to attend an international business conference. You expect to incur the total cost of SF 5,000 for lodging, meals and transportation during your stay. As of today, the spot exchange rate is $0.60/SF and the three-month forward rate is $0.63/SF. You can buy the three-month call option on SF with the exercise rate of $0.64/SF for the premium of $0.05 per SF. Assume that your expected future spot exchange rate is the same as the forward rate. The three-month interest rate is 6 percent per annum in the United States and 4 percent per annum in Switzerland.(a) Calculate your expected dollar cost of buying SF5,000 if you choose to hedge via call option on SF.(b) Calculate the future dollar cost of meeting this SF obligation if you decide to hedge using a forward contract.(c) At what future spot exchange rate will you be indifferent between the forward and option market hedges?(d) Illustrate the future dollar costs of meeting the SF payable against the future spot exchange rate under both the options and forward market hedges.Solution: (a) Total option premium = (.05)(5000) = $250. In three months, $250 is worth $253.75 = $250(1.015). At the expected future spot rate of $0.63/SF, which is less than the exercise price, you don’t expect to exercise options. Rather, you expect to buy Swiss franc at $0.63/SF. Since you are going to buy SF5,000, you expect to spend $3,150 (=.63x5,000). Thus, the total expected cost of buying SF5,000 will be the sum of $3,150 and $253.75, i.e., $3,403.75.(b) $3,150 = (.63)(5,000).(c) $3,150 = 5,000x + 253.75, where x represents the break-even future spot rate. Solving for x, we obtain x = $0.57925/SF. Note that at the break-even future spot rate, options will not be exercised.(d) If the Swiss franc appreciates beyond $0.64/SF, which is the exercise price of call option, you will exercise the option and buy SF5,000 for $3,200. The total cost of buying SF5,000 will be $3,453.75 = $3,200 + $253.75.This is the maximum you will pay.4. Boeing just signed a contract to sell a Boeing 737 aircraft to Air France. Air France will be billed €20 million which is payable in one year. The current spot exchange rate is $1.05/€ and the one -year forwa rd rate is $1.10/€. The annual interest rate is 6.0% in the U.S. and5.0% in France. Boeing is concerned with the volatile exchange rate between the dollar and the euro and would like to hedge exchange exposure.(a) It is considering two hedging alternatives: sell the euro proceeds from the sale forward or borrow euros from the Credit Lyonnaise against the euro receivable. Which alternative would you recommend? Why?(b) Other things being equal, at what forward exchange rate would Boeing be indifferent between the two hedging methods?Solution: (a) In the case of forward hedge, the future dollar proceeds will be (20,000,000)(1.10) = $22,000,000. In the case of money market hedge (MMH), the firm has to first borrow the PV of its euro receivable, i.e., 20,000,000/1.05 =€19,047,619. Then the firm should exchange this euro amount into dollars at the current spot rate to receive: (€19,047,619)($1.05/€) = $20,000,000, which can be invested at the dollar interest rate for one year to yield:$20,000,000(1.06) = $21,200,000.Clearly, the firm can receive $800,000 more by using forward hedging.(b) According to IRP, F = S(1+i $)/(1+i F ). Thus the “indifferent” forward rate will be:$ Co st Options hedge Forward hedge $3,453.75 $3,150 0 0.579 0.64 (strike $/SF $253.75F = 1.05(1.06)/1.05 = $1.06/€.5. Suppose that Baltimore Machinery sold a drilling machine to a Swiss firm and gave the Swiss client a choice of paying either $10,000 or SF 15,000 in three months.(a) In the above example, Baltimore Machinery effectively gave the Swiss client a free option to buy up to $10,000 dolla rs using Swiss franc. What is the ‘implied’ exercise exchange rate?(b) If the spot exchange rate turns out to be $0.62/SF, which currency do you think the Swiss client will choose to use for payment? What is the value of this free option for the Swiss client?(c) What is the best way for Baltimore Machinery to deal with the exchange exposure?Solution: (a) The implied exercise (price) rate is: 10,000/15,000 = $0.6667/SF.(b) If the Swiss client chooses to pay $10,000, it will cost SF16,129 (=10,000/.62). Since the Swiss client has an option to pay SF15,000, it will choose to do so. The value of this option is obviously SF1,129 (=SF16,129-SF15,000).(c) Baltimore Machinery faces a contingent exposure in the sense that it may or may not receive SF15,000 in the future. The firm thus can hedge this exposure by buying a put option on SF15,000.6. Princess Cruise Company (PCC) purchased a ship from Mitsubishi Heavy Industry. PCC owes Mitsubishi Heavy Industry 500 million yen in one year. The current spot rate is 124 yen per dollar and the one-year forward rate is 110 yen per dollar. The annual interest rate is 5% in Japan and 8% in the U.S. PCC can also buy a one-year call option on yen at the strike price of $.0081 per yen for a premium of .014 cents per yen.(a) Compute the future dollar costs of meeting this obligation using the money market hedge and the forward hedges.(b) Assuming that the forward exchange rate is the best predictor of the future spot rate, compute the expected future dollar cost of meeting this obligation when the option hedge is used.(c) At what future spot rate do you think PCC may be indifferent between the option and forward hedge?Solution: (a) In the case of forward hedge, the dollar cost will be 500,000,000/110 = $4,545,455. In the case of money market hedge, the future dollar cost will be: 500,000,000(1.08)/(1.05)(124) = $4,147,465.(b) The option premium is: (.014/100)(500,000,000) = $70,000. Its future value will be $70,000(1.08) = $75,600.At the expected future spot rate of $.0091(=1/110), which is higher than the exercise of $.0081, PCC will exercise its call option and buy ¥500,000,000 for $4,050,000 (=500,000,000x.0081).The total expected cost will thus be $4,125,600, which is the sum of $75,600 and $4,050,000.(c) When the option hedge is used, PCC will spend “at most” $4,125,000. On the other hand, when the forward hedging is used, PCC will have to spend $4,545,455 regardless of the future spot rate. This means that the options hedge dominates the forward hedge. At no future spot rate, PCC will be indifferent between forward and options hedges.7. Airbus sold an aircraft, A400, to Delta Airlines, a U.S. company, and billed $30 million payable in six months. Airbus is concerned with the euro proceeds from international sales and would like to control exchange risk. The current spot exchange rate is $1.05/€ and six-month forward exchange rate is $1.10/€ at the moment. Airbus can buy a six-month put option on U.S. dollars with a strike price of €0.95/$ for a premium of €0.02 p er U.S. dollar. Currently, six-month interest rate is 2.5% in the euro zone and 3.0% in the U.S.pute the guaranteed euro proceeds from the American sale if Airbus decides tohedge using a forward contract.b.If Airbus decides to hedge using money market instruments, what action does Airbusneed to take? What would be the guaranteed euro proceeds from the American sale in this case?c.If Airbus decides to hedge using put options on U.S. dollars, what would be the ‘expected’euro proceeds from the American sale? Assume that Airbus regards the current forward exchange rate as an unbiased predictor of the future spot exchange rate.d.At what future spot exchange rate do you think Airbus will be indifferent between theoption and money market hedge?Solution:a. Airbus will sell $30 million forward for €27,272,727 = ($30,000,000) / ($1.10/€).b. Airbus will borrow the present value of the dollar receivable, i.e., $29,126,214 = $30,000,000/1.03, and then sell the dollar proceeds spot for euros: €27,739,251. This is the euro amount that Airbus is going to keep.c. Since the expected future spot rate is less than the strike price of the put option, i.e., €0.9091< €0.95, Airbus expects to exercise the option and receive €28,500,000 = ($30,000,000)(€0.95/$). Th is is gross proceeds. Airbus spent €600,000 (=0.02x30,000,000) upfront for the option and its future cost is equal to €615,000 = €600,000 x 1.025. Thus the net euro proceeds from the American sale is €27,885,000, which is the difference between the gross proceeds and the option costs.d. At the indifferent future spot rate, the following will hold:€28,432,732 = S T (30,000,000) - €615,000.Solving for S T, we obtain the “indifference” future spot exchange rate, i.e., €0.9683/$, or $1.0327/€. Note that €28,432,732 is the future value of the proceeds under money market hedging: €28,432,732 = (€27,739,251) (1.025).Suggested solution for Mini Case: Chase Options, Inc.[See Chapter 13 for the case text]Chase Options, Inc.Hedging Foreign Currency Exposure Through Currency OptionsHarvey A. PoniachekI. Case SummaryThis case reviews the foreign exchange options market and hedging. It presents various international transactions that require currency options hedging strategies by the corporations involved. Seven transactions under a variety of circumstances are introduced that require hedging by currency options. The transactions involve hedging of dividend remittances, portfolio investment exposure, and strategic economic competitiveness. Market quotations are provided for options (and options hedging ratios), forwards, and interest rates for various maturities.II. Case Objective.The case introduces the student to the principles of currency options market and hedging strategies. The transactions are of various types that often confront companies that are involved in extensive international business or multinational corporations. The case induces students to acquire hands-on experience in addressing specific exposure and hedging concerns, including how to apply various market quotations, which hedging strategy is most suitable, and how to address exposure in foreign currency through cross hedging policies.III. Proposed Assignment Solution1. The company expects DM100 million in repatriated profits, and does not want the DM/$ exchangerate at which they convert those profits to rise above 1.70. They can hedge this exposure using DM put options with a strike price of 1.70. If the spot rate rises above 1.70, they can exercise the option, while if that rate falls they can enjoy additional profits from favorable exchange rate movements.To purchase the options would require an up-front premium of:DM 100,000,000 x 0.0164 = DM 1,640,000.With a strike price of 1.70 DM/$, this would assure the U.S. company of receiving at least:DM 100,000,000 – DM 1,640,000 x (1 + 0.085106 x 272/360)= DM 98,254,544/1.70 DM/$ = $57,796,791by exercising the option if the DM depreciated. Note that the proceeds from the repatriated profits are reduced by the premium paid, which is further adjusted by the interest foregone on this amount.However, if the DM were to appreciate relative to the dollar, the company would allow the option to expire, and enjoy greater dollar proceeds from this increase.Should forward contracts be used to hedge this exposure, the proceeds received would be:DM100,000,000/1.6725 DM/$ = $59,790,732,regardless of the movement of the DM/$ exchange rate. While this amount is almost $2 million more than that realized using option hedges above, there is no flexibility regarding the exercise date; if this date differs from that at which the repatriate profits are available, the company may be exposed to additional further current exposure. Further, there is no opportunity to enjoy any appreciation in the DM.If the company were to buy DM puts as above, and sell an equivalent amount in calls with strike price 1.647, the premium paid would be exactly offset by the premium received. This would assure that the exchange rate realized would fall between 1.647 and 1.700. If the rate rises above 1.700, the company will exercise its put option, and if it fell below 1.647, the other party would use its call; for any rate in between, both options would expire worthless. The proceeds realized would then fall between:DM 100,00,000/1.647 DM/$ = $60,716,454andDM 100,000,000/1.700 DM/$ = $58,823,529.This would allow the company some upside potential, while guaranteeing proceeds at least $1 million greater than the minimum for simply buying a put as above.Buy/Sell OptionsDM/$ Sp otPutPayoff“Put”ProfitsCallPayoff“Call”ProfitsNetProfit1. 60(1,742,846)01,742,84660,716,45460,716,4541. 61(1,742,846)01,742,84660,716,45460,716,4541. 62(1,742,846)01,742,84660,716,45460,716,4541. 63(1,742,846)01,742,84660,716,45460,716,4541. 64(1,742,846)01,742,84660,716,45460,716,4541. 65(1,742,846)60,606,0611,742,846060,606,0611. 66(1,742,846)60,240,9641,742,846060,240,9641. 67(1,742,846)59,880,2401,742,846059,880,2401. 68(1,742,846)59,523,8101,742,846059,523,8101. 69(1,742,846)59,171,5981,742,846059,171,5981. 70(1,742,846)58,823,5291,742,846058,823,5291.(1,742,858,8231,742,8058,823,7146),529465291. 72(1,742,846)58,823,5291,742,846058,823,5291. 73(1,742,846)58,823,5291,742,846058,823,5291. 74(1,742,846)58,823,5291,742,846058,823,5291. 75(1,742,846)58,823,5291,742,846058,823,5291. 76(1,742,846)58,823,5291,742,846058,823,5291. 77(1,742,846)58,823,5291,742,846058,823,5291. 78(1,742,846)58,823,5291,742,846058,823,5291. 79(1,742,846)58,823,5291,742,846058,823,5291. 80(1,742,846)58,823,5291,742,846058,823,5291. 81(1,742,846)58,823,5291,742,846058,823,5291. 82(1,742,846)58,823,5291,742,846058,823,5291. 83(1,742,846)58,823,5291,742,846058,823,5291. 84(1,742,846)58,823,5291,742,846058,823,5291. 85(1,742,846)58,823,5291,742,846058,823,529Since the firm believes that there is a good chance that the pound sterling will weaken, locking them into a forward contract would not be appropriate, because they would lose the opportunity to profit from this weakening. Their hedge strategy should follow for an upside potential to match their viewpoint. Therefore, they should purchase sterling call options, paying a premium of:5,000,000 STG x 0.0176 = 88,000 STG.If the dollar strengthens against the pound, the firm allows the option to expire, and buys sterling in the spot market at a cheaper price than they would have paid for a forward contract; otherwise, the sterling calls protect against unfavorable depreciation of the dollar.Because the fund manager is uncertain when he will sell the bonds, he requires a hedge which will allow flexibility as to the exercise date. Thus, options are the best instrument for him to use. He can buy A$ puts to lock in a floor of 0.72 A$/$. Since he is willing to forego any further currency appreciation, he can sell A$ calls with a strike price of 0.8025 A$/$ to defray the cost of his hedge (in fact he earns a net premium of A$ 100,000,000 x (0.007234 –0.007211) = A$ 2,300), while knowing that he can’t receive less than 0.72 A$/$ when redeeming his investment, and can benefit from a small appreciation of the A$.Example #3:Problem: Hedge principal denominated in A$ into US$.

The German company is bidding on a contract which they cannot be certain of winning. Thus, the need to execute a currency transaction is similarly uncertain, and using a forward or futures as a hedge is inappropriate, because it would force them to perform even if they do not win the contract.Using a sterling put option as a hedge for this transaction makes the most sense. For a premium of:12 million STG x 0.0161 = 193,200 STG,they can assure themselves that adverse movements in the pound sterling exchange rate will not diminish the profitability of the project (and hence the feasibility of their bid), while at the same time allowing the potential for gains from sterling appreciation.5. Since AMC in concerned about the adverse effects that a strengthening of the dollar would have on its business, we need to create a situation in which it will profit from such an appreciation. Purchasing a yen put or a dollar call will achieve this objective. The data in Exhibit 1, row 7 represent a 10 percent appreciation of the dollar (128.15 strike vs. 116.5 forward rate) and can be used to hedge against a similar appreciation of the dollar.For every million yen of hedging, the cost would be:Yen 100,000,000 x 0.000127 = 127 Yen.To determine the breakeven point, we need to compute the value of this option if the dollar appreciated 10 percent (spot rose to 128.15), and subtract from it the premium we paid. This profit would be compared with the profit earned on five to 10 percent of AMC’s sales (which would be lost as a result of the dollar appreciation). The number of options to be purchased which would equalize these two quantities would represent the breakeven point.Example #5:Hedge the economic cost of the depreciating Yen to AMC.If we assume that AMC sales fall in direct proportion to depreciation in the yen (i.e., a 10 percent decline in yen and 10 percent decline in sales), then we can hedge the full value of AMC’s sales. I have assumed $100 million in sales.1) Buy yen puts# contracts needed = Expected Sales *Current ¥/$ Rate / Contract size 9600 = ($100,000,000)(120¥/$) / ¥1,250,0002) Total Cost = (# contracts)(contract size)(premium)$1,524,000 = (9600)( ¥1,250,000)($0.0001275/¥)3) Floor rate = Exercise – Premium128.1499¥/$ = 128.15¥/$ - $1,524,000/12,000,000,000¥4) The payoff changes depending on the level of the ¥/$ rate.

CHAPTER 7 FUTURES AND OPTIONS ON FOREIGN EXCHANGESUGGESTED ANSWERS AND SOLUTIONS TO END-OF-CHAPTERQUESTIONS AND PROBLEMSQUESTIONS1. Explain the basic differences between the operation of a currency forward market and a futures market.Answer: The forward market is an OTC market where the forward contract for purchase or sale of foreign currency is tailor-made between the client and its international bank. No money changes hands until the maturity date of the contract when delivery and receipt are typically made. A futures contract is an exchange-traded instrument with standardized features specifying contract size and delivery date. Futures contracts are marked-to-market daily to reflect changes in the settlement price. Delivery is seldom made in a futures market. Rather a reversing trade is made to close out a long or short position.2. In order for a derivatives market to function most efficiently, two types of economic agents are needed: hedgers and speculators. Explain.Answer: Two types of market participants are necessary for the efficient operation of a derivatives market: speculators and hedgers. A speculator attempts to profit from a change in the futures price. To do this, the speculator will take a long or short position in a futures contract depending upon his expectations of future price movement. A hedger, on-the-other-hand, desires to avoid price variation by locking in a purchase price of the underlying asset through a long position in a futures contract or a sales price through a short position. In effect, the hedger passes off the risk of price variation to the speculator who is better able, or at least more willing, to bear this risk.3. Why are most futures positions closed out through a reversing trade rather than held to delivery?Answer: In forward markets, approximately 90 percent of all contracts that are initially established result in the short making delivery to the long of the asset underlying the contract. This is natural because the terms of forward contracts are tailor-made between the long and short. By contrast, only about one percent of currency futures contracts result in delivery. While futures contracts are useful for speculation and hedging, their standardized delivery dates make them unlikely to correspond to the actual future dates when foreignexchange transactions will occur. Thus, they are generally closed out in a reversing trade. In fact, the commission that buyers and sellers pay to transact in the futures market is a single amount that covers the round-trip transactions of initiating and closing out the position.4. How can the FX futures market be used for price discovery?Answer: To the extent that FX forward prices are an unbiased predictor of future spot exchange rates, the market anticipates whether one currency will appreciate or depreciate versus another. Because FX futures contracts trade in an expiration cycle, different contracts expire at different periodic dates into the future. The pattern of the prices of these cont racts provides information as to the market’s current belief about the relative future value of one currency versus another at the scheduled expiration dates of the contracts. One will generally see a steadily appreciating or depreciating pattern; however, it may be mixed at times. Thus, the futures market is useful for price discovery, i.e., obtaining the market’s forecast of the spot exchange rate at different future dates.5. What is the major difference in the obligation of one with a long position in a futures (or forward) contract in comparison to an options contract?Answer: A futures (or forward) contract is a vehicle for buying or selling a stated amount of foreign exchange at a stated price per unit at a specified time in the future. If the long holds the contract to the delivery date, he pays the effective contractual futures (or forward) price, regardless of whether it is an advantageous price in comparison to the spot price at the delivery date. By contrast, an option is a contract giving the long the right to buy or sell a given quantity of an asset at a specified price at some time in the future, but not enforcing any obligation on him if the spot price is more favorable than the exercise price. Because the option owner does not have to exercise the option if it is to his disadvantage, the option has a price, or premium, whereas no price is paid at inception to enter into a futures (or forward) contract.6. What is meant by the terminology that an option is in-, at-, or out-of-the-money?Answer: A call (put) option with S t > E (E > S t) is referred to as trading in-the-money. If S t E the option is trading at-the-money. If S t< E (E < S t) the call (put) option is trading out-of-the-money.7. List the arguments (variables) of which an FX call or put option model price is a function. How does the call and put premium change with respect to a change in the arguments?Answer: Both call and put options are functions of only six variables: S t, E, r i, r$, T andσ.When all else remains the same, the price of a European FX call (put) option will increase:1. the larger (smaller) is S,2. the smaller (larger) is E,3. the smaller (larger) is r i,4. the larger (smaller) is r$,5. the larger (smaller) r$ is relative to r i, and6. the greater is σ.When r$ and r i are not too much different in size, a European FX call and put will increase in price when the option term-to-maturity increases. However, when r$ is very much larger than r i, a European FX call will increase in price, but the put premium will decrease, when the option term-to-maturity increases. The opposite is true when r i is very much greater than r$. For American FX options the analysis is less complicated. Since a longer term American option can be exercised on any date that a shorter term option can be exercised, or a some later date, it follows that the all else remaining the same, the longer term American option will sell at a price at least as large as the shorter term option.PROBLEMS1. Assume today’s settlement price on a CME EUR futures contract is $1.3140/EUR. You have a short position in one contract. Your performance bond account currently has a balance of $1,700. The next three days’ settlement prices are $1.3126, $1.3133, and $1.3049. Calculate the chan ges in the performance bond account from daily marking-to-market and the balance of the performance bond account after the third day.Solution: $1,700 + [($1.3140 - $1.3126) + ($1.3126 - $1.3133)+ ($1.3133 - $1.3049)] x EUR125,000 = $2,837.50,where EUR125,000 is the contractual size of one EUR contract.2. Do problem 1 again assuming you have a long position in the futures contract.Solution: $1,700 + [($1.3126 - $1.3140) + ($1.3133 - $1.3126) + ($1.3049 - $1.3133)] x EUR125,000 = $562.50,where EUR125,000 is the contractual size of one EUR contract.With only $562.50 in your performance bond account, you would experience a margin call requesting that additional funds be added to your performance bond account to bring the balance back up to the initial performance bond level.3. Using the quotations in Exhibit 7.3, calculate the face value of the open interest in the June 2005 Swiss franc futures contract.Solution: 2,101 contracts x SF125,000 = SF262,625,000.where SF125,000 is the contractual size of one SF contract.4. Using the quotations in Exhibit 7.3, note that the June 2005 Mexican peso futures contract has a price of $0.08845. You believe the spot price in June will be $0.09500. What speculative position would you enter into to attempt to profit from your beliefs? Calculate your anticipated profits, assuming you take a position in three contracts. What is the size of your profit (loss) if the futures price is indeed an unbiased predictor of the future spot price and this price materializes?Solution: If you expect the Mexican peso to rise from $0.08845 to $0.09500, you would take a long position in futures since the futures price of $0.08845 is less than your expected spot price.Your anticipated profit from a long position in three contracts is: 3 x ($0.09500 - $0.08845) x MP500,000 = $9,825.00, where MP500,000 is the contractual size of one MP contract.If the futures price is an unbiased predictor of the expected spot price, the expected spot price is the futures price of $0.08845/MP. If this spot price materializes, you will not have any profits or losses from your short position in three futures contracts: 3 x ($0.08845 - $0.08845) x MP500,000 = 0.5. Do problem 4 again assuming you believe the June 2005 spot price will be $0.08500.Solution: If you expect the Mexican peso to depreciate from $0.08845 to $0.07500, you would take a short position in futures since the futures price of $0.08845 is greater than your expected spot price.Your anticipated profit from a short position in three contracts is: 3 x ($0.08845 - $0.07500) x MP500,000 = $20,175.00.If the futures price is an unbiased predictor of the future spot price and this price materializes, you will not profit or lose from your long futures position.6. George Johnson is considering a possible six-month $100 million LIBOR-based, floating-rate bank loan to fund a project at terms shown in the table below. Johnson fears a possible rise in the LIBOR rate by December and wants to use the December Eurodollar futures contract to hedge this risk. The contract expires December 20, 1999, has a US$ 1 million contract size, and a discount yield of7.3 percent.Johnson will ignore the cash flow implications of marking to market, initial margin requirements, and any timing mismatch between exchange-traded futures contract cash flows and the interest payments due in March.Loan TermsSeptember 20, 1999 December 20, 1999 March 20, 2000 •Borrow $100 million at •Pay interest for first three •Pay back principal September 20 LIBOR + 200 months plus interestbasis points (bps) •Roll loan over at•September 20 LIBOR = 7% December 20 LIBOR +200 bpsLoan First loan payment (9%) Second paymentinitiated and futures contract expires and principal↓↓↓•••9/20/99 12/20/99 3/20/00a.

Describe the strip hedge that Johnson could use and explain how it hedges the 12-month loan (specify number of contracts). No calculations are needed.CFA Guideline Answera. The basis point value (BPV) of a Eurodollar futures contract can be found by substituting the contract specifications into the following money market relationship:BPV FUT = Change in Value = (face value) x (days to maturity / 360) x (change in yield)= ($1 million) x (90 / 360) x (.0001)= $25The number of contract, N, can be found by:N = (BPV spot) / (BPV futures)= ($2,500) / ($25)= 100ORN = (value of spot position) / (face value of each futures contract)= ($100 million) / ($1 million)= 100ORN = (value of spot position) / (value of futures position)= ($100,000,000) / ($981,750)where value of futures position = $1,000,000 x [1 – (0.073 / 4)]102 contractsTherefore on September 20, Johnson would sell 100 (or 102) December Eurodollar futures contracts at the 7.3 percent yield. The implied LIBOR rate in December is 7.3 percent as indicated by the December Eurofutures discount yield of 7.3 percent. Thus a borrowing rate of 9.3 percent (7.3 percent + 200 basis points) can be locked in if the hedge is correctly implemented.A rise in the rate to 7.8 percent represents a 50 basis point (bp) increase over the implied LIBOR rate. For a 50 basis point increase in LIBOR, the cash flow on the short futures position is:= ($25 per basis point per contract) x 50 bp x 100 contracts= $125,000.However, the cash flow on the floating rate liability is:= -0.098 x ($100,000,000 / 4)= - $2,450,000.Combining the cash flow from the hedge with the cash flow from the loan results in a net outflow of $2,325,000, which translates into an annual rate of 9.3 percent:= ($2,325,000 x 4) / $100,000,000 = 0.093This is precisely the implied borrowing rate that Johnson locked in on September 20. Regardless of the LIBOR rate on December 20, the net cash outflow will be $2,325,000, which translates into an annualized rate of 9.3 percent. Consequently, the floating rate liability has been converted to a fixed rate liability in the sense that the interest rate uncertainty associated with the March 20 payment (using the December 20 contract) has been removed as of September 20.b. In a strip hedge, Johnson would sell 100 December futures (for the March payment), 100 March futures (for the June payment), and 100 June futures (for the September payment). The objective is to hedge each interest rate payment separately using the appropriate number of contracts. The problem is the same as in Part A except here three cash flows are subject to rising rates and a strip of futures is used tohedge this interest rate risk. This problem is simplified somewhat because the cash flow mismatch between the futures and the loan payment is ignored. Therefore, in order to hedge each cash flow, Johnson simply sells 100 contracts for each payment. The strip hedge transforms the floating rate loan into a strip of fixed rate payments. As was done in Part A, the fixed rates are found by adding 200 basis points to the implied forward LIBOR rate indicated by the discount yield of the three different Eurodollar futures contracts. The fixed payments will be equal when the LIBOR term structure is flat for the first year.7. Jacob Bower has a liability that:•has a principal balance of $100 million on June 30, 1998,•accrues interest quarterly starting on June 30, 1998,•pays interest quarterly,•has a one-year term to maturity, and•calculates interest due based on 90-day LIBOR (the London Interbank OfferedRate).Bower wishes to hedge his remaining interest payments against changes in interest rates.Bower has correctly calculated that he needs to sell (short) 300 Eurodollar futures contracts to accomplish the hedge. He is considering the alternative hedging strategies outlined in the following table.Initial Position (6/30/98) in90-Day LIBOR Eurodollar ContractsStrategy A Strategy BContract Month (contracts) (contracts)September 1998 300 100December 1998 0 100March 1999 0 100a. Explain why strategy B is a more effective hedge than strategy A when the yield curveundergoes an instantaneous nonparallel shift.b. Discuss an interest rate scenario in which strategy A would be superior to strategy B.CFA Guideline Answera. Strategy B’s SuperiorityStrategy B is a strip hedge that is constructed by selling (shorting) 100 futures contracts maturing in each of the next three quarters. With the strip hedge in place, each quarter of the coming year is hedged against shifts in interest rates for that quarter. The reason Strategy B will be a more effective hedge than Strategy A for Jacob Bower is that Strategy B is likely to work well whether a parallel shift or a nonparallel shift occurs over the one-year term of Bower’s liability. That is, regardless of what happens to the term structure, Strategy B structures the futures hedge so that the rates reflected by the Eurodollar futures cash price match the applicable rates for the underlying liability-the 90day LIBOR-based rate on Bower’s liability. The same is not true for Strategy A. Because Jacob Bower’s liability carries a floating interest rate that resets quarterly, he needs a strategy that provides a series of three-month hedges. Strategy A will need to be restructured when the three-month September contract expires. In particular, if the yield curve twists upward (futures yields rise more for distant expirations than for near expirations), Strategy A will produce inferior hedge results.b. Scenario in Which Strategy A is SuperiorStrategy A is a stack hedge strategy that initially involves selling (shorting) 300 September contracts. Strategy A is rarely better than Strategy B as a hedging or risk-reduction strategy. Only from the perspective of favorable cash flows is Strategy A better than Strategy B. Such cash flows occur only in certain interest rate scenarios. For example Strategy A will work as well as Strategy B for Bower’s liability if interest rates (instantaneously) change in parallel fashion. Another interest rate scenario where Strategy A outperforms Strategy B is one in which the yield curve rises but with a twist so that futures yields rise more for near expirations than for distant expirations. Upon expiration of the September contract, Bower will have to roll out his hedge by selling 200 December contracts to hedge the remaining interest payments. This action will have the effect that the cash flow from Strategy A will be larger than the cash flow from Strategy B because the appreciation on the 300 short September futures contracts will be larger than the cumulative appreciation in the 300 contracts shorted in Strategy B (i.e., 100 September, 100 December, and 100 March). Consequently, the cash flow from Strategy A will more than offset the increase in the interest payment on the liability, whereas the cash flow from Strategy B will exactly offset the increase in the interest payment on the liability.8. Use the quotations in Exhibit 7.7 to calculate the intrinsic value and the time value of the 97 September Japanese yen American call and put options.Solution: Premium - Intrinsic Value = Time Value97 Sep Call 2.08 - Max[95.80 – 97.00 = - 1.20, 0] = 2.08 cents per 100 yen97 Sep Put 2.47 - Max[97.00 – 95.80 = 1.20, 0] = 1.27 cents per 100 yen9. Assume spot Swiss franc is $0.7000 and the six-month forward rate is $0.6950. What is the minimum price that a six-month American call option with a striking price of $0.6800 should sell for in a rational market? Assume the annualized six-month Eurodollar rate is 3 ½ percent.Solution:Note to Instructor: A complete solution to this problem relies on the boundary expressions presented in footnote 3 of the text of Chapter 7.C a≥Max[(70 - 68), (69.50 - 68)/(1.0175), 0]≥Max[ 2, 1.47, 0] = 2 cents10. Do problem 9 again assuming an American put option instead of a call option.Solution: P a≥Max[(68 - 70), (68 - 69.50)/(1.0175), 0]≥Max[ -2, -1.47, 0] = 0 cents11. Use the European option-pricing models developed in the chapter to value the call of problem 9 and the put of problem 10. Assume the annualized volatility of the Swiss franc is 14.2 percent. This problem can be solved using the FXOPM.xls spreadsheet.Solution:d1 = [ln(69.50/68) + .5(.142)2(.50)]/(.142)√.50 = .2675d2 = d1 - .142√.50 = .2765 - .1004 = .1671N(d1) = .6055N(d2) = .5664N(-d1) = .3945N(-d2) = .4336C e = [69.50(.6055) - 68(.5664)]e-(.035)(.50) = 3.51 centsP e = [68(.4336) - 69.50(.3945)]e-(.035)(.50) = 2.03 cents12. Use the binomial option-pricing model developed in the chapter to value the call of problem 9.The volatility of the Swiss franc is 14.2 percent.Solution: The spot rate at T will be either 77.39¢ = 70.00¢(1.1056) or 63.32¢ = 70.00¢(.9045), where u = e.142 .50= 1.1056 and d = 1/u= .9045. At the exercise price of E= 68, the option will only be exercised at time T if the Swiss franc appreciates; its exercise value would be C uT= 9.39¢ = 77.39¢ - 68. If the Swiss franc depreciates it would not be rational to exercise the option; its value would be C dT = 0.The hedge ratio is h = (9.39 – 0)/(77.39 – 63.32) = .6674.Thus, the call premium is:C0= Max{[69.50(.6674) – 68((70/68)(.6674 – 1) +1)]/(1.0175), 70 – 68}= Max[1.64, 2] = 2 cents per SF.MINI CASE: THE OPTIONS SPECULATORA speculator is considering the purchase of five three-month Japanese yen call options with a striking price of 96 cents per 100 yen. The premium is 1.35 cents per 100 yen. The spot price is 95.28 cents per 100 yen and the 90-day forward rate is 95.71 cents. The speculator believes the yen will appreciate to $1.00 per 100 yen over the next three months. As the speculator’s assistant, you have been asked to prepare the following:1. Graph the call option cash flow schedule.2. Determine the speculator’s profit if the yen appreciates to $1.00/100 yen.3. Determine the speculator’s profit if the yen only appreciates to the forward rate.4. Determine the future spot price at which the speculator will only break even.Suggested Solution to the Options Speculator:1.2. (5 x ¥6,250,000) x [(100 - 96) - 1.35]/10000 = $8,281.25.3. Since the option expires out-of-the-money, the speculator will let the option expire worthless. He will only lose the option premium.4. S T = E + C = 96 + 1.35 = 97.35 cents per 100 yen.。

CHAPTER 8 MANAGEMENT OF TRANSACTION EXPOSURE SUGGESTED ANSWERS AND SOLUTIONS TO END-OF-CHAPTER QUESTIONS AND PROBLEMSQUESTIONS1. How would you define transaction exposure? How is it different from economic exposure?Answer: Transaction exposure is the sensitivity of realized domestic currency values of the firm’s contractual cash flows denominated in foreign currencies to unexpected changes in exchange rates. Unlike economic exposure, transaction exposure is well-defined and short-term.2. Discuss and compare hedging transaction exposure using the forward contract vs. money market instruments. When do the alternative hedging approaches produce the same result?Answer: Hedging transaction exposure by a forward contract is achieved by selling or buying foreign currency receivables or payables forward. On the other hand, money market hedge is achieved by borrowing or lending the present value of foreign currency receivables or payables, thereby creating offsetting foreign currency positions. If the interest rate parity is holding, the two hedging methods are equivalent.3. Discuss and compare the costs of hedging via the forward contract and the options contract.Answer: There is no up-front cost of hedging by forward contracts. In the case of options hedging, however, hedgers should pay the premiums for the contracts up-front. The cost of forward hedging, however, may be realized ex post when the hedger regrets his/her hedging decision.4. What are the advantages of a currency options contract as a hedging tool compared with the forward contract?Answer: The main advantage of using options contracts for hedging is that the hedger can decide whether to exercise options upon observing the realized future exchange rate. Options thus provide a hedge against ex post regret that forward hedger might have to suffer. Hedgers can only eliminate the downside risk while retaining the upside potential.5. Suppose your company has purchased a put option on the German mark to manage exchange exposure associated with an account receivable denominated in that currency. In this case, your company can be said to have an ‘insurance’ policy on its receivable. Explain in what sense this is so.Answer: Your company in this case knows in advance that it will receive a certain minimum dollar amount no matter what might happen to the $/€exchange rate. Furthermore, if the German mark appreciates, your company will benefit from the rising euro.6. Recent surveys of corporate exchange risk management practices indicate that many U.S. firms simply do not hedge. How would you explain this result?Answer: There can be many possible reasons for this. First, many firms may feel that they are not really exposed to exchange risk due to product diversification, diversified markets for their products, etc. Second, firms may be using self-insurance against exchange risk. Third, firms may feel that shareholders can diversify exchange risk themselves, rendering corporate risk management unnecessary.7. Should a firm hedge? Why or why not?Answer: In a perfect capital market, firms may not need to hedge exchange risk. But firms can add to their value by hedging if markets are imperfect. First, if management knows about the firm’s exposure better than shareholders, the firm, not its shareholders, should hedge. Second, firms may be able to hedge at a lower cost. Third, if default costs are significant, corporate hedging can be justifiable because it reduces the probability of default. Fourth, if the firm faces progressive taxes, it can reduce tax obligations by hedging which stabilizes corporate earnings.8. Using an example, discuss the possible effect of hedging on a firm’s tax obligations.Answer: One can use an example similar to the one presented in the chapter.9. Explain contingent exposure and discuss the advantages of using currency options to manage this type of currency exposure.Answer: Companies may encounter a situation where they may or may not face currency exposure. In this situation, companies need options, not obligations, to buy or sell a given amount of foreign exchange they may or may not receive or have to pay. If companies either hedge using forward contracts or do not hedge at all, they may face definite currency exposure.10. Explain cross-hedging and discuss the factors determining its effectiveness.Answer: Cross-hedging involves hedging a position in one asset by taking a position in another asset. The effectiveness of cross-hedging would depend on the strength and stability of the relationship between the two assets.PROBLEMS1. Cray Research sold a super computer to the Max Planck Institute in Germany on credit and invoiced €10 million payable in six months. Currently, the six-month forward exchange rate is $1.10/€ and the foreign exchange advisor for Cray Research predicts that the spot rate is likely to be $1.05/€ in six months.(a) What is the expected gain/loss from the forward hedging?(b) If you were the financial manager of Cray Research, would you recommend hedging this euro receivable? Why or why not?(c) Suppose the foreign exchange advisor predicts that the future spot rate will be the same as the forward exchange rate quoted today. Would you recommend hedging in this case? Why or why not?Solution: (a) Expected gain($) = 10,000,000(1.10 – 1.05)= 10,000,000(.05)= $500,000.(b) I would recommend hedging because Cray Research can increase the expected dollar receipt by $500,000 and also eliminate the exchange risk.(c) Since I eliminate risk without sacrificing dollar receipt, I still would recommend hedging.2. IBM purchased computer chips from NEC, a Japanese electronics concern, and was billed ¥250 million payable in three months. Currently, the spot exchange rate is ¥105/$ and the three-month forward rate is ¥100/$. The three-month money market interest rate is 8 percent per annum in the U.S. and 7 percent per annum in Japan. The management of IBM decided to use the money market hedge to deal with this yen account payable.(a) Explain the process of a money market hedge and compute the dollar cost of meeting the yen obligation.(b) Conduct the cash flow analysis of the money market hedge.Solution: (a). Let’s first compute the PV of ¥250 million, i.e.,250m/1.0175 = ¥245,700,245.7So if the above yen amount is invested today at the Japanese interest rate for three months, the maturity value will be exactly equal to ¥25 million which is the amount of payable.To buy the above yen amount today, it will cost:$2,340,002.34 = ¥250,000,000/105.The dollar cost of meeting this yen obligation is $2,340,002.34 as of today.(b)___________________________________________________________________Transaction CF0 CF1____________________________________________________________________1.

You plan to visit Geneva, Switzerland in three months to attend an international business conference. You expect to incur the total cost of SF 5,000 for lodging, meals and transportation during your stay. As of today, the spot exchange rate is $0.60/SF and the three-month forward rate is $0.63/SF. You can buy the three-month call option on SF with the exercise rate of $0.64/SF for the premium of $0.05 per SF. Assume that your expected future spot exchange rate is the same as the forward rate. The three-month interest rate is 6 percent per annum in the United States and 4 percent per annum in Switzerland.(a) Calculate your expected dollar cost of buying SF5,000 if you choose to hedge via call option on SF.(b) Calculate the future dollar cost of meeting this SF obligation if you decide to hedge using a forward contract.(c) At what future spot exchange rate will you be indifferent between the forward and option market hedges?(d) Illustrate the future dollar costs of meeting the SF payable against the future spot exchange rate under both the options and forward market hedges.Solution: (a) Total option premium = (.05)(5000) = $250. In three months, $250 is worth $253.75 = $250(1.015). At the expected future spot rate of $0.63/SF, which is less than the exercise price, y ou don’t expect to exercise options. Rather, you expect to buy Swiss franc at $0.63/SF. Since you are going to buy SF5,000, you expect to spend $3,150 (=.63x5,000). Thus, the total expected cost of buying SF5,000 will be the sum of $3,150 and $253.75, i.e., $3,403.75.(b) $3,150 = (.63)(5,000).(c) $3,150 = 5,000x + 253.75, where x represents the break-even future spot rate. Solving for x, we obtain x = $0.57925/SF. Note that at the break-even future spot rate, options will not be exercised.(d) If the Swiss franc appreciates beyond $0.64/SF, which is the exercise price of call option, you will exercise the option and buy SF5,000 for $3,200. The total cost of buying SF5,000 will be $3,453.75 = $3,200 + $253.75.This is the maximum you will pay.4. Boeing just signed a contract to sell a Boeing 737 aircraft to Air France. Air France will be billed €20 million which is payable in one year. The current spot exchange rate is $1.05/€ and the one -year forward rate is $1.10/€. The annual interest rate is 6.0% in the U.S. and5.0% in France. Boeing is concerned with the volatile exchange rate between the dollar and the euro and would like to hedge exchange exposure.(a) It is considering two hedging alternatives: sell the euro proceeds from the sale forward or borrow euros from the Credit Lyonnaise against the euro receivable. Which alternative would you recommend? Why?(b) Other things being equal, at what forward exchange rate would Boeing be indifferent between the two hedging methods?Solution: (a) In the case of forward hedge, the future dollar proceeds will be (20,000,000)(1.10) = $22,000,000. In the case of money market hedge (MMH), the firm has to first borrow the PV of its euro receivable, i.e., 20,000,000/1.05 =€19,047,619. Then the firm should exchange this euro amount into dollars at the current spot rate to receive: (€19,047,619)($1.05/€) = $20,000,000, which can be invested at the dollar interest rate for one year to yield:$ Cost Options hedge Forward hedge $3,453.75 $3,150 0 0.579 0.64 (strike price) $/SF$253.75$20,000,000(1.06) = $21,200,000.Clearly, the firm can receive $800,000 more by using forward hedging.(b) According to IRP, F = S(1+i$)/(1+i F). Thus the “indifferent” forward rate will be:F = 1.05(1.06)/1.05 = $1.06/€.5. Suppose that Baltimore Machinery sold a drilling machine to a Swiss firm and gave the Swiss client a choice of paying either $10,000 or SF 15,000 in three months.(a) In the above example, Baltimore Machinery effectively gave the Swiss client a free option to buy up to $10,000 dollars using Swiss franc. What is the ‘implied’ exercise exchange rate?(b) If the spot exchange rate turns out to be $0.62/SF, which currency do you think the Swiss client will choose to use for payment? What is the value of this free option for the Swiss client?(c) What is the best way for Baltimore Machinery to deal with the exchange exposure?Solution: (a) The implied exercise (price) rate is: 10,000/15,000 = $0.6667/SF.(b) If the Swiss client chooses to pay $10,000, it will cost SF16,129 (=10,000/.62). Since the Swiss client has an option to pay SF15,000, it will choose to do so. The value of this option is obviously SF1,129 (=SF16,129-SF15,000).(c) Baltimore Machinery faces a contingent exposure in the sense that it may or may not receive SF15,000 in the future. The firm thus can hedge this exposure by buying a put option on SF15,000.6. Princess Cruise Company (PCC) purchased a ship from Mitsubishi Heavy Industry. PCC owes Mitsubishi Heavy Industry 500 million yen in one year. The current spot rate is 124 yen per dollar and the one-year forward rate is 110 yen per dollar. The annual interest rate is 5% in Japan and 8% in the U.S. PCC can also buy a one-year call option on yen at the strike price of $.0081 per yen for a premium of .014 cents per yen.(a) Compute the future dollar costs of meeting this obligation using the money market hedge and the forward hedges.(b) Assuming that the forward exchange rate is the best predictor of the future spot rate, compute the expected future dollar cost of meeting this obligation when the option hedge is used.(c) At what future spot rate do you think PCC may be indifferent between the option and forward hedge?Solution: (a) In the case of forward hedge, the dollar cost will be 500,000,000/110 = $4,545,455. In the case of money market hedge, the future dollar cost will be: 500,000,000(1.08)/(1.05)(124)= $4,147,465.(b) The option premium is: (.014/100)(500,000,000) = $70,000. Its future value will be $70,000(1.08) = $75,600.At the expected future spot rate of $.0091(=1/110), which is higher than the exercise of $.0081, PCC will exercise its call option and buy ¥500,000,000 for $4,050,000 (=500,000,000x.0081).The total expected cost will thus be $4,125,600, which is the sum of $75,600 and $4,050,000.(c) When the option hedge is used, PCC will spend “at most” $4,125,000. On the other hand, when the forward hedging is used, PCC will have to spend $4,545,455 regardless of the future spot rate. This means that the options hedge dominates the forward hedge. At no future spot rate, PCC will be indifferent between forward and options hedges.7. Airbus sold an aircraft, A400, to Delta Airlines, a U.S. company, and billed $30 million payable in six months. Airbus is concerned with the euro proceeds from international sales and would like to control exchange risk. The current spot exchange rate is $1.05/€ and six-month forward exchange rate is $1.10/€ at the moment. Airbus can buy a six-month put option on U.S. dollars with a strike price of€0.95/$ for a premium of €0.02 per U.S. dollar. Currently, six-month interest rate is 2.5% in the euro zone and 3.0% in theU.S.pute the guaranteed euro proceeds from the American sale if Airbus decides tohedge using a forward contract.b.If Airbus decides to hedge using money market instruments, what action doesAirbus need to take? What would be the guaranteed euro proceeds from the American sale in this case?c.If Airbus decides to hedge using put options on U.S. dollars, what would be the‘expected’ euro proceeds from the American sale? Assume that Airbus regards the current forward exchange rate as an unbiased predictor of the future spot exchange rate.d.At what future spot exchange rate do you think Airbus will be indifferent betweenthe option and money market hedge?Solution:a. Airbus will sell $30 million forward for €27,272,727 = ($30,000,000) / ($1.10/€).b. Airbus will borrow the present value of the dollar receivable, i.e., $29,126,214 = $30,000,000/1.03, and then sell the dollar proceeds spot for euros: €27,739,251. This is the euro amount that Airbus is going to keep.c. Since the expected future spot rate is less than the strike price of the put option, i.e., €0.9091< €0.95, Airbus expects to exercise the option and receive €28,500,000 = ($30,000,000)(€0.95/$). This is gross proceeds. Airbus spent €600,000 (=0.02x30,000,000) upfront for the option and its future cost is equal to €615,000 = €600,000 x 1.025. Thus the net euro proceeds from the American sale is €27,885,000, which is the difference between the gross proceeds and the option costs.d. At the indifferent future spot rate, the following will hold:€28,432,732 = S T(30,000,000) - €615,000.Solving for S T, we obtain the “indifference” future spot exchange rate, i.e., €0.9683/$, or $1.0327/€. Note that €28,432,732 is the future value of the proceeds under money market hedging:€28,432,732 = (€27,739,251) (1.025).Suggested solution for Mini Case: Chase Options, Inc.[See Chapter 13 for the case text]Chase Options, Inc.Hedging Foreign Currency Exposure Through Currency OptionsHarvey A. PoniachekI. Case SummaryThis case reviews the foreign exchange options market and hedging. It presents various international transactions that require currency options hedging strategies by the corporations involved. Seven transactions under a variety of circumstances are introduced that require hedging by currency options. The transactions involve hedging of dividend remittances, portfolio investment exposure, and strategic economic competitiveness. Market quotations are provided for options (and options hedging ratios), forwards, and interest rates for various maturities.II. Case Objective.The case introduces the student to the principles of currency options market and hedging strategies. The transactions are of various types that often confront companies that are involved in extensive international business or multinational corporations. The case induces students to acquire hands-on experience in addressing specific exposure and hedging concerns, including how to apply various market quotations, which hedging strategy is most suitable, and how to address exposure in foreign currency through cross hedging policies.III. Proposed Assignment Solution1. The company expects DM100 million in repatriated profits, and does not want the DM/$ exchange rate at which they convert those profits to rise above 1.70. They can hedge this exposure using DM put options with a strike price of 1.70. If the spot rate rises above 1.70, they can exercise the option, while if that rate falls they can enjoy additional profits from favorable exchange rate movements.To purchase the options would require an up-front premium of:DM 100,000,000 x 0.0164 = DM 1,640,000.With a strike price of 1.70 DM/$, this would assure the U.S. company of receiving at least:DM 100,000,000 – DM 1,640,000 x (1 + 0.085106 x 272/360)= DM 98,254,544/1.70 DM/$ = $57,796,791by exercising the option if the DM depreciated. Note that the proceeds from the repatriated profits are reduced by the premium paid, which is further adjusted by the interest foregone on this amount.However, if the DM were to appreciate relative to the dollar, the company would allow the option to expire, and enjoy greater dollar proceeds from this increase.Should forward contracts be used to hedge this exposure, the proceeds received would be:DM100,000,000/1.6725 DM/$ = $59,790,732,regardless of the movement of the DM/$ exchange rate. While this amount is almost $2 million more than that realized using option hedges above, there is no flexibilityregarding the exercise date; if this date differs from that at which the repatriate profits are available, the company may be exposed to additional further current exposure. Further, there is no opportunity to enjoy any appreciation in the DM.If the company were to buy DM puts as above, and sell an equivalent amount in calls with strike price 1.647, the premium paid would be exactly offset by the premium received. This would assure that the exchange rate realized would fall between 1.647 and 1.700. If the rate rises above 1.700, the company will exercise its put option, and if it fell below 1.647, the other party would use its call; for any rate in between, both options would expire worthless. The proceeds realized would then fall between:DM 100,00,000/1.647 DM/$ = $60,716,454andDM 100,000,000/1.700 DM/$ = $58,823,529.This would allow the company some upside potential, while guaranteeing proceeds at least $1 million greater than the minimum for simply buying a put as above.Buy/Sell OptionsDM/$Spot Put Payoff “Put”ProfitsCallPayoff“Call”Profits Net Profit1.60(1,742,846)01,742,84660,716,45460,716,4541.61(1,742,846)01,742,84660,716,45460,716,454 1.62(1,742,846)01,742,84660,716,45460,716,4541.63(1,742,846)01,742,84660,716,45460,716,4541.64(1,742,846)01,742,84660,716,4560,716,45441.65(1,742,846)60,606,061,742,846060,606,06111.66(1,742,846)60,240,961,742,846060,240,96441,742,846059,880,240 1.67(1,742,846)59,880,241.68(1,742,846)59,523,811,742,846059,523,8101,742,846059,171,598 1.69(1,742,846)59,171,5981.70(1,742,846)58,823,521,742,846058,823,52991,742,846058,823,529 1.71(1,742,846)58,823,5291.72(1,742,846)58,823,521,742,846058,823,52991,742,846058,823,529 1.73(1,742,846)58,823,5291.74(1,742,846)58,823,521,742,846058,823,52991,742,846058,823,529 1.75(1,742,846)58,823,5291.76(1,742,846)58,823,521,742,846058,823,52991.77(1,742,846)58,823,521,742,846058,823,52991.78(1,742,846)58,823,521,742,846058,823,52991.79(1,742,846)58,823,521,742,846058,823,52991,742,846058,823,5291.80(1,742,846)58,823,5291,742,846058,823,5291.81(1,742,846)58,823,5291.82(1,742,846)58,823,521,742,846058,823,52991,742,846058,823,5291.83(1,742,846)58,823,5291.84(1,742,846)58,823,521,742,846058,823,52991,742,846058,823,5291.85(1,742,846)58,823,529Since the firm believes that there is a good chance that the pound sterling will weaken, locking them into a forward contract would not be appropriate, because they would lose the opportunity to profit from this weakening. Their hedge strategy should follow for an upside potential to match their viewpoint. Therefore, they should purchase sterling call options, paying a premium of:5,000,000 STG x 0.0176 = 88,000 STG.If the dollar strengthens against the pound, the firm allows the option to expire, and buys sterling in the spot market at a cheaper price than they would have paid for a forward contract; otherwise, the sterling calls protect against unfavorable depreciation of the dollar.Because the fund manager is uncertain when he will sell the bonds, he requires a hedge which will allow flexibility as to the exercise date. Thus, options are the best instrument for him to use. He can buy A$ puts to lock in a floor of 0.72 A$/$. Since he is willing to forego any further currency appreciation, he can sell A$ calls with a strike price of 0.8025 A$/$ to defray the cost of his hedge (in fact he earns a net premium of A$ 100,000,000 x (0.007234 – 0.007211) = A$ 2,300), while knowing that he can’t receive less than 0.72 A$/$ when redeeming his investment, and can benefit from a small appreciation of the A$.Example #3:Problem: Hedge principal denominated in A$ into US$.

The German company is bidding on a contract which they cannot be certain of winning. Thus, the need to execute a currency transaction is similarly uncertain, and using a forward or futures as a hedge is inappropriate, because it would force them to perform even if they do not win the contract.Using a sterling put option as a hedge for this transaction makes the most sense. Fora premium of:12 million STG x 0.0161 = 193,200 STG,they can assure themselves that adverse movements in the pound sterling exchange rate will not diminish the profitability of the project (and hence the feasibility oftheir bid), while at the same time allowing the potential for gains from sterling appreciation.5. Since AMC in concerned about the adverse effects that a strengthening of the dollar would have on its business, we need to create a situation in which it will profit from such an appreciation. Purchasing a yen put or a dollar call will achieve this objective. The data in Exhibit 1, row 7 represent a 10 percent appreciation of the dollar (128.15 strike vs. 116.5 forward rate) and can be used to hedge against a similar appreciation of the dollar.For every million yen of hedging, the cost would be:Yen 100,000,000 x 0.000127 = 127 Yen.To determine the breakeven point, we need to compute the value of this option if the dollar appreciated 10 percent (spot rose to 128.15), and subtract from it the premium we paid. This profit would be compared with the profit earned on five to 10 percent of AMC’s sales (which would be lost as a result of the dollar appreciation). The number of options to be purchased which would equalize these two quantities would represent the breakeven point.Example #5:Hedge the economic cost of the depreciating Yen to AMC.If we assume that AMC sales fall in direct proportion to depreciation in the yen (i.e., a 10 percent decline in yen and 10 percent decline in sales), then we can hedge the full value of AMC’s sales. I have a ssumed $100 million in sales.1) Buy yen puts# contracts needed = Expected Sales *Current ¥/$ Rate / Contract size9600 = ($100,000,000)(120¥/$) / ¥1,250,0002) Total Cost = (# contracts)(contract size)(premium)$1,524,000 = (9600)( ¥1,250,000)($0.0001275/¥)3) Floor rate = Exercise – Premium128.1499¥/$ = 128.15¥/$ - $1,524,000/12,000,000,000¥4) The payoff changes depending on the level of the ¥/$ rate.

International Business Methods. Snyder Golf Co., a U.S. firm that sells high-quality golf clubs in the U.S., wants to expand internationally by selling the same golf clubs in Brazil.a. Describe the tradeoffs that are involved for each method (such as exporting, direct foreign investment, etc.) that Snyder could use to achieve its goal.ANSWER: Snyder can export the clubs, but the transportation expenses may be high. If could establish a subsidiary in Brazil to produce and sell the clubs, but this may require a large investment of funds. It could use licensing, in which it specifies to a Brazilian firm how to produce the clubs. In this way, it does not have to establish its own subsidiary there.b. Which method would you recommend for this firm? Justify your recommendation. ANSWER: If the amount of golf clubs to be sold in Brazil is small, it may decide to export. However, if the expected sales level is high, it may benefit from licensing. If it is confident that the expected sales level will remain high, it may be willing to establish a subsidiary. The wages are lower in Brazil, and the large investment needed to establish a subsidiary may be worthwhile.8. Comparative Advantage.a. Explain how the theory of comparative advantage relates to the need for international business. ANSWER: The theory of comparative advantage implies that countries should specialize in production, thereby relying on other countries for some products. Consequently, there is a need for international business.b. Explain how the product cycle theory relates to the growth of an MNC.ANSWER: The product cycle theory suggests that at some point in time, the firm will attempt to capitalize on its perceived advantages in markets other than where it was initially established.10. Valuation of Wal-Mart’s International Business. In addition to all of its stores in the U.S., Wal-Mart has 11 stores in Argentina, 24 stores in Brazil, 214 stores in Canada, 29 stores in China, 92 stores in Germany, 15 stores in South Korea, 611 stores in Mexico, and 261 stores in the U.K. Consider the value of Wal-Mart as being composed of two parts, a U.S. part (due to business in the U.S.) and a non-U.S. part (due to business in other countries). Explain how to determine the present value (in dollars) of the non-U.S. part assuming that you had access to all the details of Wal-Mart businesses outside the U.S.ANSWER: The non-U.S. part can be measured as the present value of future dollar cash flows resulting from the non-U.S. businesses. Based on recent earnings data for each store and applying an expected growth rate, you can estimate the remitted earnings that will come from each country in each year in the future. You can convert those cash flows to dollars using a forecasted exchange rate per year. Determine the present value of cash flows of all stores within one country. Then repeat the process for other countries. Then add up all the present values that you estimated to derive a consolidated present value of all non-U.S. subsidiaries.15. International Joint Venture. Anheuser-Busch, the producer of Budweiser and other beers, has recently expanded into Japan by engaging in a joint venture with Kirin Brewery, the largest brewery in Japan. The joint venture enables Anheuser-Busch to have its beer distributed through Kirin’s distribution channels in Japan. In addition, it can utilize Kirin’s facilities to produce beer that will be sold locally. In return, Anheuser-Busch provides information about the American beer market to Kirin.a. Explain how the joint venture can enable Anheuser-Busch to achieve its objective of maximizing shareholder wealth.ANSWER: The joint venture creates a way for Anheuser-Busch to distribute Budweiser throughout Japan. It enables Anheuser-Busch to penetrate the Japanese market without requiring a substantial investment in Japan.b. Explain how the joint venture can limit the risk of the international business.ANSWER: The joint venture has limited risk because Anheuser-Busch does not need to establish its own distribution network in Japan. Thus, Anheuser-Busch may be able to use a smaller investment for the international business, and there is a higher probability that the international business will be successful.c. Many international joint ventures are intended to circumvent barriers that normally prevent foreign competition. What barrier in Japan is Anheuser-Busch circumventing as a result of the joint venture? What barrier in the United States is Kirin circumventing as a result of the joint venture?ANSWER: Anheuser-Busch is able t o benefit from Kirin’s distribution system in Japan, which would not normally be so accessible. Kirin is able to learn more about how Anheuser-Busch expanded its product across numerous countries, and therefore breaks through an “information”barrier.d. Explain how Anheuser-Busch could lose some of its market share in countries outside Japan as a result of this particular joint venture.ANSWER: Anheuser-Busch could lose some of its market share to Kirin as a result of explaining its worldwide expansion strategies to Kirin. However, it appears that Anheuser-Busch expects the potential benefits of the joint venture to outweigh any potential adverse effects.24. Global Competition. Explain why more standardized product specifications across countries can increase global competition.ANSWER: Standardized product specifications allow firms to more easily expand their business across other countries, which increases global competition.Chapter 24. Free Trade. There has been considerable momentum to reduce or remove trade barriers in an effort to achieve “free trade.” Yet, one disgruntled executive of an exporting firm stated, “Free trade is not conceivable; we are always at the mercy of the exchange rate. Any country can use this mechanism to impose trade bar riers.” What does this statement mean?ANSWER: This statement implies that even if there were no explicit barriers, a government could attempt to manipulate exchange rates to a level that would effectively reduce foreign competition. For example, a U.S. firm may be discouraged from attempting to export to Japan if the value of the dollar is very high against the yen. The prices of the U.S. goods from the Japanese perspective are too high because of the strong dollar. The reverse situation could also be possible in which a Japanese exporting firm is priced out of the U.S. market because of a strong yen (weak dollar). [Answer is based on opinion.]8. International Investments. In recent years many U.S.-based MNCs have increased their investments in foreign securities, which are not as susceptible to negative shocks in the U.S. market. Also, when MNCs believe that U.S. securities are overvalued, they can pursue non-U.S. securities that are driven by a different market. Moreover, in periods of low U.S. interest rates, U.S. corporations tend to seek investments in foreign securities. In general, the flow of funds into foreign countries tends to decline when U.S. investors anticipate a strong dollar.a. Explain how expectations of a strong dollar can affect the tendency of U.S. investors to invest abroad.ANSWER: A weak dollar would discourage U.S. investors from investing abroad. It can cause the investors to purchase foreign currency (when investing) at a higher exchange rate than the exchange rate at which they would sell the currency (when the investment is liquidated).b. Explain how low U.S. interest rates can affect the tendency of U.S.-based MNCs to invest abroad.ANSWER: Low U.S. interest rates can encourage U.S.-based MNCs to invest abroad, as investors seek higher returns on their investment than they can earn in the U.S.c. In general terms, what is the attraction of foreign investments to U.S. investors?ANSWER: The main attraction is potentially higher returns. The international stocks can outperform U.S. stocks, and international bonds can outperform U.S. bonds. However, there is no guarantee that the returns on international investments will be so favorable. Some investors may also pursue international investments to diversify their investment portfolio, which can possibly reduce risk.10. Exchange Rate Effects on Trade.a. Explain why a stronger dollar could enlarge the U.S. balance of trade deficit. Explain why a weaker dollar could affect the U.S. balance of trade deficit.ANSWER: A stronger dollar makes U.S. exports more expensive to importers and may reduceimports. It makes U.S. imports cheap and may increase U.S. imports. A weaker home currency increases the prices of imports purchased by the home country and reduces the prices paid by foreign businesses for the home country’s exports. This should cause a decrease in the home country’s demand for imports and an increase in the foreign demand for the home country’s exports, and therefore increase the current account. However, this relationship can be distorted by other factors.b. It is sometimes suggested that a floating exchange rate will adjust to reduce or eliminate any current account deficit. Explain why this adjustment would occur.ANSWER: A current account deficit reflects a net sale of the home currency in exchange for other currencies. This places downward pressure on that home currency’s value. If the currency weakens, it will reduce the home demand for foreign goods (since goods will now be more expensive), and will increase the home export volume (since exports will appear cheaper to foreign countries).c. Why does the exchange rate not always adjust to a current account deficit?ANSWER: In some cases, the home currency will remain strong even though a current account deficit exists, since other factors (such as international capital flows) can offset the forces placed on the currency by the current account.13. Effects of Tariffs. Assume a simple world in which the U.S. exports soft drinks and beer to France and imports wine from France. If the U.S. imposes large tariffs on the French wine, explain the likely impact on the values of the U.S. beverage firms, U.S. wine producers, the French beverage firms, and the French wine producers.ANSWER: The U.S. wine producers benefit from the U.S. tariffs, while the French wine producers are adversely affected. The French government would likely retaliate by imposing tariffs on the U.S. beverage firms, which would adversely affect their value. The French beverage firms would benefit.15. Demand for Exports. A relatively small U.S. balance of trade deficit is commonly attributed toa strong demand for U.S. exports. What do you think is the underlying reason for the strong demand for U.S. exports?ANSWER: The strong demand for U.S. exports is commonly attributed to strong foreign economies or to a weak dollar.Chapter 35. International Financial Markets. Recently, Wal-Mart established two retail outlets in the city of Shenzhen, China, which has a population of 3.7 million. These outlets are massive and contain products purchased locally as well as imports. As Wal-Mart generates earnings beyond what it needs in Shenzhen, it may remit those earnings back to the United States. Wal-Mart is likely to build additional outlets in Shenzhen or in other Chinese cities in the future.a. Explain how the Wal-Mart outlets in China would use the spot market in foreign exchange. ANSWER: The Wal-Mart stores in China need other currencies to buy products from other countries, and must convert the Chinese currency (yuan) into the other currencies in the spot market to purchase these products. They also could use the spot market to convert excess earnings denominated in yuan into dollars, which would be remitted to the U.S. parent.b. Explain how Wal-Mart might utilize the international money market when it is establishing other Wal-Mart stores in Asia.ANSWER: Wal-Mart may need to maintain some deposits in the Eurocurrency market that can be used (when needed) to support the growth of Wal-Mart stores in various foreign markets. When some Wal-Mart stores in foreign markets need funds, they borrow from banks in the Eurocurrency market. Thus, the Eurocurrency market serves as a deposit or lending source for Wal-Mart and other MNCs on a short-term basis.c. Explain how Wal-Mart could use the international bond market to finance the establishment of new outlets in foreign markets.ANSWER: Wal-Mart could issue bonds in the Eurobond market to generate funds needed to establish new outlets. The bonds may be denominated in the currency that is needed; then, once the stores are established, some of the cash flows generated by those stores could be used to pay interest on the bonds.11. Foreign Exchange. You just came back from Canada, where the Canadian dollar was worth $.70. You still have C$200 from your trip and could exchange them for dollars at the airport, but the airport foreign exchange desk will only buy them for $.60. Next week, you will be going to Mexico and will need pesos. The airport foreign exchange desk will sell you pesos for $.10 per peso. You met a tourist at the airport who is from Mexico and is on his way to Canada. He is willing to buy your C$200 for 130 pesos. Should you accept the offer or cash the Canadian dollars in at the airport? Explain.ANSWER: Exchange with the tourist. If you exchange the C$ for pesos at the foreign exchange desk, the cross-rate is $.60/$10 = 6. Thus, the C$200 would be exchanged for 120 pesos (computed as 200 ×6). If you exchange Canadian dollars for pesos with the tourist, you will receive 130 pesos.15. Exchange Rate Effects on Borrowing. Explain how the appreciation of the Japanese yen against the U.S. dollar would affect the return to a U.S. firm that borrowed Japanese yen and used the proceeds for a U.S. project.ANSWER: If the Japanese yen appreciates over the borrowing period, this implies that the U.S. firm converted yen to U.S. dollars at a lower exchange rate than the rate at which it paid for yen at the time it would repay the loan. Thus, it is adversely affected by the appreciation. Its cost of borrowing will be higher as a result of this appreciation.20. Interest Rates. Why do interest rates vary among countries? Why are interest rates normally similar for those European countries that use the euro as their currency? Offer a reason why the government interest rate of one country could be slightly higher than that of the government interest rate of another country, even though the euro is the currency used in both countries.ANSWER: Interest rates in each country are based on the supply of funds and demand for funds for a given currency. However, the supply and demand conditions for the euro are dictated by all participating countries in aggregate, and do not vary among participating countries. Yet, the government interest rate in one country that uses the euro could be slightly higher than others that use the euro if it is subject to default risk. The higher interest rate would reflect a risk premium.21. Forward Contract. The Wolfpack Corporation is a U.S. exporter that invoices its exports to the United Kingdom in British pounds. If it expects that the pound will appreciate against the dollar in the future, should it hedge its exports with a forward contract? Explain.ANSWER: The forward contract can hedge future receivables or payables in foreign currencies to insulate the firm against exchange rate risk. Yet, in this case, the Wolfpack Corporation should not hedge because it would benefit from appreciation of the pound when it converts the pounds to dollars.Chapter 43. Inflation Effects on Exchange Rates. Assume that the U.S. inflation rate becomes high relative to Canadian inflation. Other things being equal, how should this affect the (a) U.S. demand for Canadian dollars, (b) supply of Canadian dollars for sale, and (c) equilibrium value of the Canadian dollar?ANSWER: Demand for Canadian dollars should increase, supply of Canadian dollars for sale should decrease, and the Canadian dollar’s value should increase.12. Factors Affecting Exchange Rates. Mexico tends to have much higher inflation than the United States and also much higher interest rates than the United States. Inflation and interest rates are much more volatile in Mexico than in industrialized countries. The value of the Mexican peso is typically more volatile than the currencies of industrialized countries from a U.S. perspective; it has typically depreciated from one year to the next, but the degree of depreciation has varied substantially. The bid/ask spread tends to be wider for the peso than for currencies of industrialized countries.a. Identify the most obvious economic reason for the persistent depreciation of the peso. ANSWER: The high inflation in Mexico places continual downward pressure on the value of the peso.b. High interest rates are commonly expected to strengthen a country’s currency because they can encourage foreign investment in securities in that country, which results in the exchange of other currencies for that currency. Yet, the peso’s value has declined against the dollar over most years even though Mexican interest rates are typically much higher than U.S. interest rates. Thus, it appears that the high Mexican interest rates do not attract substantial U.S. investment in Mexico’s securities. Why do you think U.S. investors do not try to capitalize on the high interest rates in Mexico?ANSWER: The high interest rates in Mexico result from expectations of high inflation. That is, the real interest rate in Mexico may not be any higher than the U.S. real interest rate. Given the high inflationary expectations, U.S. investors recognize the potential weakness of the peso, which could more than offset the high interest rate (when they convert the pesos back to dollars at the end of the investment period). Therefore, the high Mexican interest rates do not encourage U.S. investment in Mexican securities, and do not help to strengthen the value of the peso.c. Why do you think the bid/ask spread is higher for pesos than for currencies of industrialized countries? How does this affect a U.S. firm that does substantial business in Mexico?ANSWER: The bid/ask spread is wider because the banks that provide foreign exchange services are subject to more risk when they maintain currencies such as the peso that could decline abruptly at any time. A wider bid/ask spread adversely affects the U.S. firm that does business in Mexico because it increases the transactions costs associated with conversion of dollars to pesos, or pesos to dollars.14. Aggregate Effects on Exchange Rates. Assume that the United States invests heavily in government and corporate securities of Country K. In addition, residents of Country K invest heavily in the United States. Approximately $10 billion worth of investment transactions occur between these two countries each year. The total dollar value of trade transactions per year is about $8 million. This information is expected to also hold in the future. Because your firm exports goods to Country K, your job as international cash manager requires you to forecast the value of Country K’s currency (the “krank”) with respect to the dollar. Explain how each of the following conditions will affect the value of the krank, holding other things equal. Then, aggregate all of these impacts to develop an ov erall forecast of the krank’s movement against the dollar.a. U.S. inflation has suddenly increased substantially, while Country K’s inflation remains low. ANSWER: Increased U.S. demand for the krank. Decreased supply of kranks for sale. Upward pressure in the krank’s value.b. U.S. interest rates have increased substantially, while Country K’s interest rates remain low. Investors of both countries are attracted to high interest rates.ANSWER: Decreased U.S. demand for the krank. Increased supply of kranks for sale. Downward pressure on the krank’s value.c. The U.S. income level increased substantially, while Country K’s income level has remained unchanged.ANSWER: Increased U.S. demand for the krank. Upward pressure on the krank’s value.d. The U.S. is expected to impose a small tariff on goods imported from Country K. ANSWER: The tariff will cause a decrease in the United States’ desire for Country K’s goods, and will therefore reduce the demand for kranks for sale. Downward pressure on the krank’s value.e. Combine all expected impacts to develop an overall forecast.ANSWER: Two of the scenarios described above place upward pressure on the value of the krank. However, these scenarios are related to trade, and trade flows are relatively minor between the U.S. and Country K. The interest rate scenario places downward pressure on the krank’s value. Since the interest rates affect capital flows and capital flows dominate trade flows between the U.S. and Country K, the interest rate scenario should overwhelm all other scenarios. Thus, when considering the importance of implications of all scenarios, the krank is expected to depreciate.22. Speculation. Blue Demon Bank expects that the Mexican peso will depreciate against the dollar from its spot rate of $.15 to $.14 in 10 days. The following interbank lending and borrowingin the interbank market, depending on which currency it wants to borrow.a. How could Blue Demon Bank attempt to capitalize on its expectations without using deposited funds? Estimate the profits that could be generated from this strategy.ANSWER: Blue Demon Bank can capitalize on its expectations about pesos (MXP) as follows:1. Borrow MXP70 million2. Convert the MXP70 million to dollars:MXP70,000,000 × $.15 = $10,500,0003. Lend the dollars through the interbank market at 8.0% annualized over a 10-day period. The amount accumulated in 10 days is:$10,500,000 × [1 + (8% × 10/360)] = $10,500,000 × [1.002222] = $10,523,3334. Repay the peso loan. The repayment amount on the peso loan is:MXP70,000,000 × [1 + (8.7% × 10/360)] = 70,000,000 × [1.002417]=MXP70,169,1675. Based on the expected spot rate of $.14, the amount of dollars needed to repay the peso loan is: MXP70,169,167 × $.14 = $9,823,6836. After repaying the loan, Blue Demon Bank will have a speculative profit (if its forecasted exchange rate is accurate) of:$10,523,333 – $9,823,683 = $699,650b. Assume all the preceding information with this exception: Blue Demon Bank expects the peso to appreciate from its present spot rate of $.15 to $.17 in 30 days. How could it attempt to capitalize on its expectations without using deposited funds? Estimate the profits that could be generated from this strategy.ANSWER: Blue Demon Bank can capitalize on its expectations as follows:1. Borrow $10 million2. Convert the $10 million to pesos (MXP):$10,000,000/$.15 = MXP 66, 666,6673. Lend the pesos through the interbank market at 8.5% annualized over a 30-day period. The amount accumulated in 30 days is:MXP66,666,667 × [1 + (8.5% × 30/360)] = 66,666,667 × [1.007083] = MXP67,138,8894. Repay the dollar loan. The repayment amount on the dollar loan is:$10,000,000 × [1 + (8.3% × 30/360)] = $10,000,000 × [1.006917] = $10,069,1705. Convert the pesos to dollars to repay the loan. The amount of dollars to be received in 30 days (based on the expected spot rate of $.17) is:MXP67,138,889 × $.17 = $11,413,6116. The profits are determined by estimating the dollars available after repaying the loan:$11,413,611 – $10,069,170 = $1,344,44123. SpeculationDiamond Bank expects that the Singapore dollar will depreciate against the dollar from its spotDiamond Bank considers borrowing 10 million Singapore dollars in the interbank market andinvesting the funds in dollars for 60 days. Estimate the profits(or losses) that could be earned from this strategy. Should Diamond Bank pursue this strategy?ANSWER:Borrow S$10,000,000 and convert to U.S. $:S$10,000,000 × $.43 = $4,300,000Invest funds for 60 days. The rate earned in the U.S. for 60 days is:7% × (60/360) = 1.17%Total amount accumulated in 60 days:$4,300,000 × (1 + .0117) = $4,350,310Convert U.S. $ back to S$ in 60 days:$4,350,310/$.42 = S$10,357,881The rate to be paid on loan is:.24 × (60/360) = .04Amount owed on S$ loan is:S$10,000,000 × (1 + .04) = S$10,400,000This strategy results in a loss:S$10,357,881 – S$10,400,000 = –S$42,119Diamond Bank should not pursue this strategy.Chapter 52. Risk of Currency Futures. Currency futures markets are commonly used as a means of capitalizing on shifts in currency values, because the value of a futures contract tends to move in line with the change in the corresponding currency value. Recently, many currencies appreciated against the dollar. Most speculators anticipated that these currencies would continue to strengthen and took large buy positions in currency futures. However, the Fed intervened in the foreign exchange market by immediately selling foreign currencies in exchange for dollars, causing an abrupt decline in the values of foreign currencies (as the dollar strengthened). Participants that had purchased currency futures contracts incurred large losses. One floor broker responded to the effects of the Fed's intervention by immediately selling 300 futures contracts on British pounds (with a value of about $30 million). Such actions caused even more panic in the futures market.a. Explain why the central bank s intervention caused such panic among currency futures traders with buy positions.ANSWER: Futures prices on pounds rose in tandem with the value of the pound. However, when central banks intervened to support the dollar, the value of the pound declined, and so did values of futures contracts on pounds. So traders with long (buy) positions in these contracts experienced losses because the contract values declined.b. Explain why the floor broker s willingness to sell 300 pound futures contracts at the going market rate aroused such concern. What might this action signal to other brokers?ANSWER: Normally, this order would have been sold in pieces. This action could signal a desperate situation in which many investors sell futures contracts at any price, which places more downward pressure on currency future prices, and could cause a crisis.c. Explain why speculators with short (sell) positions could benefit as a result of the central bank s intervention.ANSWER: The central bank intervention placed downward pressure on the pound and other European currencies. Thus, the values of futures contracts on these currencies declined. Traders that had short positions in futures would benefit because they could now close out their short positions by purchasing the same contracts that they had sold earlier. Since the prices of futures contracts declined, they would purchase the contracts for a lower price than the price at which they initially sold the contracts.d. Some traders with buy positions may have responded immediately to the central bank s intervention by selling futures contracts. Why would some speculators with buy positions leave their positions unchanged or even increase their positions by purchasing more futures contracts in response to the central bank s intervention?ANSWER: Central bank intervention sometimes has only a temporary effect on exchange rates. Thus, the European currencies could strengthen after a temporary effect caused by central bank intervention. Traders have to predict whether natural market forces will ultimately overwhelm any pressure induced as a result of central bank intervention. ]。
国际财务管理课后习题答案chapter-8
国际财务管理课后习题答案chapter-8CHAPTER 8 MANAGEMENT OF TRANSACTION EXPOSURE SUGGESTED ANSWERS AND SOLUTIONS TO END-OF-CHAPTER QUESTIONS ANDPROBLEMSQUESTIONS1. How would you define transaction exposure? How is it different from economic exposure?Answer: T ransaction exposure is the sensitivity of realized domestic currency values of the firm’s contractual cash flows denominated in foreign currencies to unexpected changes in exchange rates. Unlike economic exposure, transaction exposure is well-defined and short-term.2. Discuss and compare hedging transaction exposure using the forward contract vs. money market instruments. When do the alternative hedging approaches produce the same result?Answer: Hedging transaction exposure by a forward contract is achieved by selling or buying foreign currency receivables or payables forward. On the other hand, money market hedge is achieved by borrowing or lending the present value of foreign currency receivables or payables, thereby creating offsetting foreign currency positions. If the interest rate parity is holding, the two hedging methods are equivalent.3. Discuss and compare the costs of hedging via the forward contract and the options contract.Answer: There is no up-front cost of hedging by forward contracts. In the case of options hedging, however, hedgers should pay the premiums for the contracts up-front. The cost of forward hedging, however, may be realized ex post when the hedger regrets his/her hedging decision.4. What are the advantages of a currency options contract as a hedging tool compared with the forward contract?Answer: The main advantage of using options contracts for hedging is that the hedger can decide whether to exercise options upon observing the realized future exchange rate. Options thus provide a hedge against ex post regret that forward hedger might have to suffer. Hedgers can only eliminateIM-1the downside risk while retaining the upside potential.5. Suppose your company has purchased a put option on the German mark to manage exchange exposure associated with an account receivable denominated in that currency. In this case, your company can be said to have an ‘insurance’ policy on its receivable. Explain in what sense this is so.Answer: Your company in this case knows in advance that it will receive a certain minimum dollar amount no matter what might happen to the $/€ exchange rate. Furthermore, if the German mark appreciates, your company will benefit from the rising euro.6. Recent surveys of corporate exchange risk management practices indicate that many U.S. firms simply do not hedge. How would you explain this result?Answer: There can be many possible reasons for this. First, many firms may feel that they are not really exposed to exchange risk due to product diversification, diversified markets for their products, etc. Second, firms may be using self-insurance against exchange risk. Third, firms may feel that shareholders can diversify exchange risk themselves, rendering corporate risk management unnecessary.7. Should a firm hedge? Why or why not?Answer: In a perfect capital market, firms may not need to hedge exchange risk. But firms can add to their value by hedging if markets are imperfect. First, if management knows about the firm’s exposure better than shareho lders, the firm, not its shareholders, should hedge. Second, firms may be able to hedge at a lower cost. Third, if default costs are significant, corporate hedging can be justifiable because it reduces the probability of default. Fourth, if the firm faces progressive taxes, it can reduce tax obligations by hedging which stabilizes corporate earnings.8. Using an example, discuss the possible effect of hedging on a firm’s tax obligations.Answer: One can use an example similar to the one presented in the chapter.IM-29. Explain contingent exposure and discuss the advantages of using currency options to manage this type of currency exposure.Answer: Companies may encounter a situation where they may or may not face currency exposure. In this situation, companies need options, not obligations, to buy or sell a given amount of foreign exchange they may or may not receive or have to pay. If companies either hedge using forward contracts or do not hedge at all, they may face definite currency exposure.10. Explain cross-hedging and discuss the factors determining its effectiveness.Answer: Cross-hedging involves hedging a position in one asset by taking a position in another asset. The effectiveness of cross-hedging would depend on the strength and stability of the relationship between the two assets.IM-3PROBLEMS1. Cray Research sold a super computer to the Max Planck Institute in Germany on credit and invoiced €10 million payable in six months. Currently, the six-month forward exchange rate is $1.10/€ and the fo reign exchange advisor for Cray Research predicts that the spot rate is likely to be $1.05/€ in six months.(a) What is the expected gain/loss from the forward hedging?(b) If you were the financial manager of Cray Research, would you recommend hedging this euro receivable? Why or why not?(c) Suppose the foreign exchange advisor predicts that the future spot rate will be the same as the forward exchange rate quoted today. Would you recommend hedging in this case? Why or why not?Solution: (a) Expected gain($) = 10,000,000(1.10 – 1.05)= 10,000,000(.05)= $500,000.(b) I would recommend hedging because Cray Research can increase the expected dollar receipt by $500,000 and also eliminate the exchange risk.(c) Since I eliminate risk without sacrificing dollar receipt, I still would recommend hedging.2. IBM purchased computer chips from NEC, a Japanese electronics concern, and was billed ¥250 million payable in three months. Currently, the spot exchange rate is ¥105/$ and the three-month forward rate is ¥100/$. The three-month money market interest rate is 8 percent per annum in the U.S. and 7 percent per annum in Japan. The management of IBM decided to use the money market hedge to deal with this yen account payable.(a) Explain the process of a money market hedge and compute the dollar cost of meeting the yen obligation.(b) Conduct the cash flow analysis of the money market hedge.Solution: (a). Let’s first compute the PV of ¥250 million, i.e.,250m/1.0175 = ¥245,700,245.7So if the above yen amount is invested today at the Japanese interest rate for three months, the maturity value will be exactly equal to ¥25 million which is the amount of payable.IM-4To buy the above yen amount today, it will cost:$2,340,002.34 = ¥250,000,000/105.The dollar cost of meeting this yen obligation is $2,340,002.34 as of today.(b)___________________________________________________________________Transaction CF0 CF1____________________________________________________________________1.

You plan to visit Geneva, Switzerland in three months to attend an international business conference. You expect to incur the total cost of SF 5,000 for lodging, meals and transportation during your stay. As of today, the spot exchange rate is $0.60/SF and the three-month forward rate is $0.63/SF. You can buy the three-month call option on SF with the exercise rate of $0.64/SF for the premium of $0.05 per SF. Assume that your expected future spot exchange rate is the same as the forward rate. The three-month interest rate is 6 percent per annum in the United States and 4 percent per annum in Switzerland.(a) Calculate your expected dollar cost of buying SF5,000 if you choose to hedge via call option on SF.(b) Calculate the future dollar cost of meeting this SF obligation if you decide to hedge using a forward contract.(c) At what future spot exchange rate will you be indifferent between the forward and option market hedges?(d) Illustrate the future dollar costs of meeting the SF payable against the future spot exchange rate under both the options and forward market hedges.Solution: (a) Total option premium = (.05)(5000) = $250. In three months, $250 is worth $253.75 = $250(1.015). At the expected future spot rate of $0.63/SF, which is less than the exercise price, you don’t expect to exercise options. Rather, you expect to buy Swiss franc at $0.63/SF. Since you are going to buy SF5,000, you expect to spend $3,150 (=.63x5,000). Thus, the total expected cost ofIM-5buying SF5,000 will be the sum of $3,150 and $253.75, i.e., $3,403.75.(b) $3,150 = (.63)(5,000).(c) $3,150 = 5,000x + 253.75, where x represents the break-even future spot rate. Solving for x, we obtain x = $0.57925/SF. Note that at the break-even future spot rate, options will not be exercised.IM-6IM-7(d) If the Swiss franc appreciates beyond $0.64/SF, which is the exercise price of call option, you will exercise the option and buy SF5,000 for $3,200. The total cost of buying SF5,000 will be $3,453.75 = $3,200 + $253.75.This is the maximum you will pay.4. Boeing just signed a contract to sell a Boeing 737 aircraft to Air France. Air France will be billed €20 million which is payable in one year. The current spot exchange rate is $1.05/€ and the one -year forward rate is $1.10/€. The annual interest rate is 6.0% in the U.S. and5.0% in France. Boeing is concerned with the volatile exchange rate between the dollar and the euro and would like to hedge exchange exposure.(a) It is considering two hedging alternatives: sell the euro proceeds from the sale forward or borrow euros from the Credit Lyonnaise against the euro receivable. Which alternative would you recommend? Why?(b) Other things being equal, at what forward exchange rate would Boeing be indifferent between the two hedging methods?Solution: (a) In the case of forward hedge, the future dollar proceeds will be (20,000,000)(1.10) = $22,000,000. In the case of money market hedge (MMH), the firm has to first borrow the PV of its euro receivable, i.e., 20,000,000/1.05 =€19,047,619. Then the firm should exchange this euro amount into dollars at the current spot rate to receive: (€19,047,619)($1.05/€) = $20,000,000, which can be invested at the dollar interest rate for one year to yield:$20,000,000(1.06) = $21,200,000.Clearly, the firm can receive $800,000 more by using forward hedging.$ Co Options Forward $3,453.75 $3,150 0 0.0.64 (strike$/S $253.75(b) According to IRP, F = S(1+i$)/(1+i F). Thus the “indifferent” forward rate will be:F = 1.05(1.06)/1.05 = $1.06/€.5. Suppose that Baltimore Machinery sold a drilling machine to a Swiss firm and gave the Swiss client a choice of paying either $10,000 or SF 15,000 in three months.(a) In the above example, Baltimore Machinery effectively gave the Swiss client a free option to buy up to $10,000 dollars using Swiss franc. What is the ‘implied’ exercise exchange rate?(b) If the spot exchange rate turns out to be $0.62/SF, which currency do you think the Swiss client will choose to use for payment? What is the value of this free option for the Swiss client?(c) What is the best way for Baltimore Machinery to deal with the exchange exposure?Solution: (a) The implied exercise (price) rate is: 10,000/15,000 = $0.6667/SF.(b) If the Swiss client chooses to pay $10,000, it will cost SF16,129 (=10,000/.62). Since the Swiss client has an option to pay SF15,000, it will choose to do so. The value of this option is obviously SF1,129 (=SF16,129-SF15,000).(c) Baltimore Machinery faces a contingent exposure in the sense that it may or may not receive SF15,000 in the future. The firm thus can hedge this exposure by buying a put option on SF15,000.6. Princess Cruise Company (PCC) purchased a ship from Mitsubishi Heavy Industry. PCC owes Mitsubishi Heavy Industry 500 million yen in one year. The current spot rate is 124 yen per dollar and the one-year forward rate is 110 yen per dollar. The annual interest rate is 5% in Japan and 8% in the U.S. PCC can also buy a one-year call option on yen at the strike price of $.0081 per yen for a premium of .014 cents per yen.(a) Compute the future dollar costs of meeting this obligation using the money market hedge and the forward hedges.(b) Assuming that the forward exchange rate is the best predictor of the future spot rate, compute the expected future dollar cost of meeting this obligation when the option hedge is used.(c) At what future spot rate do you think PCC may be indifferent between the option and forward hedge?Solution: (a) In the case of forward hedge, the dollar cost will be 500,000,000/110 = $4,545,455. In the case of money market hedge, the future dollar cost will be: 500,000,000(1.08)/(1.05)(124)= $4,147,465.IM-8(b) The option premium is: (.014/100)(500,000,000) = $70,000. Its future value will be $70,000(1.08) = $75,600.At the expected future spot rate of $.0091(=1/110), which is higher than the exercise of $.0081, PCC will exercise its call option and buy ¥500,000,000 for $4,050,000 (=500,000,000x.0081).The total expected cost will thus be $4,125,600, which is the sum of $75,600 and $4,050,000.(c) When the option hedge is use d, PCC will spend “at most” $4,125,000. On the other hand, when the forward hedging is used, PCC will have to spend $4,545,455 regardless of the future spot rate. This means that the options hedge dominates the forward hedge. At no future spot rate, PCC will be indifferent between forward and options hedges.7. Airbus sold an aircraft, A400, to Delta Airlines, a U.S. company, and billed $30 million payable in six months. Airbus is concerned with the euro proceeds from international sales and would like to control exchange risk. The current spot exchange rate is $1.05/€ and six-month forward exchange rate is $1.10/€ at the moment. Airbus can buy a six-month put option on U.S. dollars witha strike price of €0.95/$ for a premium of €0.02 per U.S. dollar. Curr ently, six-month interest rate is2.5% in the euro zone and3.0% in the U.S.pute the guaranteed euro proceeds from the American sale if Airbus decides to hedge usinga forward contract.b.If Airbus decides to hedge using money market instruments, what action does Airbus need totake? What would be the guaranteed euro proceeds from the American sale in this case?c.If Airbus decides to hedge using put options on U.S. dollars, what would be the ‘expected’ europroceeds from the American sale? Assume that Airbus regards the current forward exchange rate as an unbiased predictor of the future spot exchange rate.d.At what future spot exchange rate do you think Airbus will be indifferent between the optionand money market hedge?Solution:a. Airbus will se ll $30 million forward for €27,272,727 = ($30,000,000) / ($1.10/€).b. Airbus will borrow the present value of the dollar receivable, i.e., $29,126,214 = $30,000,000/1.03, and then sell the dollar proceeds spot for euros: €27,739,251. This is the euro amo unt that Airbus is going to keep.c. Since the expected future spot rate is less than the strike price of the put option, i.e., €0.9091< €0.95, Airbus expects to exercise the option and receive €28,500,000 = ($30,000,000)(€0.95/$). This isIM-9gross proceeds. Airbus spent €600,000 (=0.02x30,000,000) upfront for the option and its future cost is equal to €615,000 = €600,000 x 1.025. Thus the net euro proceeds from the American sale is €27,885,000, which is the difference between the gross proceeds and the opt ion costs.d. At the indifferent future spot rate, the following will hold:€28,432,732 = S T (30,000,000) - €615,000.Solving for S T, we obtain the “indifference” future spot exchange rate, i.e., €0.9683/$, or $1.0327/€. Note that €28,432,732 is the futu re value of the proceeds under money market hedging:€28,432,732 = (€27,739,251) (1.025).Suggested solution for Mini Case: Chase Options, Inc.[See Chapter 13 for the case text]Chase Options, Inc.Hedging Foreign Currency Exposure Through Currency OptionsHarvey A. PoniachekI. Case SummaryThis case reviews the foreign exchange options market and hedging. It presents various international transactions that require currency options hedging strategies by the corporations involved. Seven transactions under a variety of circumstances are introduced that require hedging by currency options. The transactions involve hedging of dividend remittances, portfolio investment exposure, and strategic economic competitiveness. Market quotations are provided for options (and options hedging ratios), forwards, and interest rates for various maturities.II. Case Objective.The case introduces the student to the principles of currency options market and hedging strategies. The transactions are of various types that often confront companies that are involved in extensive international business or multinational corporations. The case induces students to acquire hands-on experience in addressing specific exposure and hedging concerns, including how to apply various market quotations, which hedging strategy is most suitable, and how to address exposure in foreigncurrency through cross hedging policies.III. Proposed Assignment Solution1. The company expects DM100 million in repatriated profits, and does not want the DM/$ exchange rate at which they convert those profits to rise above 1.70. They can hedge this exposure using DM put options with a strike price of 1.70. If the spot rate rises above 1.70, they can exercise the option, while if that rate falls they can enjoy additional profits from favorable exchange rate movements.To purchase the options would require an up-front premium of:DM 100,000,000 x 0.0164 = DM 1,640,000.With a strike price of 1.70 DM/$, this would assure the U.S. company of receiving at least:DM 100,000,000 – DM 1,640,000 x (1 + 0.085106 x 272/360)= DM 98,254,544/1.70 DM/$ = $57,796,791by exercising the option if the DM depreciated. Note that the proceeds from the repatriated profits are reduced by the premium paid, which is further adjusted by the interest foregone on this amount.However, if the DM were to appreciate relative to the dollar, the company would allow the option to expire, and enjoy greater dollar proceeds from this increase.Should forward contracts be used to hedge this exposure, the proceeds received would be:DM100,000,000/1.6725 DM/$ = $59,790,732,regardless of the movement of the DM/$ exchange rate. While this amount is almost $2 million more than that realized using option hedges above, there is no flexibility regarding the exercise date; if this date differs from that at which the repatriate profits are available, the company may be exposed to additional further current exposure. Further, there is no opportunity to enjoy any appreciation in the DM.If the company were to buy DM puts as above, and sell an equivalent amount in calls with strike price 1.647, the premium paid would be exactly offset by the premium received. This would assure that the exchange rate realized would fall between 1.647 and 1.700. If the rate rises above 1.700, the company will exercise its put option, and if it fell below 1.647, the other party would use its call; for any rate in between, both options would expire worthless. The proceeds realized would then fall between:DM 100,00,000/1.647 DM/$ = $60,716,454andDM 100,000,000/1.700 DM/$ = $58,823,529.This would allow the company some upside potential, while guaranteeing proceeds at least $1 million greater than the minimum for simply buying a put as above.Buy/Sell OptionsDM/$Spot Put Payoff “Put”Profits Call Payoff“Call”Profits Net Profit1.60 (1,742,846) 0 1,742,846 60,716,454 60,716,454 1.61 (1,742,846) 0 1,742,846 60,716,454 60,716,454 1.62 (1,742,846) 0 1,742,846 60,716,454 60,716,454 1.63 (1,742,846) 0 1,742,846 60,716,454 60,716,454 1.64 (1,742,846) 0 1,742,846 60,716,454 60,716,454 1.65 (1,742,846) 60,606,061 1,742,846 0 60,606,061 1.66 (1,742,846) 60,240,964 1,742,846 0 60,240,964 1.67 (1,742,846) 59,880,240 1,742,846 0 59,880,240 1.68 (1,742,846) 59,523,810 1,742,846 0 59,523,810 1.69 (1,742,846) 59,171,598 1,742,846 0 59,171,598 1.70 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.71 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.72 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.73 (1,742,846) 58,823,529 1,742,846 0 58,823,5291.74 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.75 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.76 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.77 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.78 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.79 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.80 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.81 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.82 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.83 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.84 (1,742,846) 58,823,529 1,742,846 0 58,823,529 1.85 (1,742,846) 58,823,529 1,742,846 0 58,823,529Since the firm believes that there is a good chance that the pound sterling will weaken, locking them into a forward contract would not be appropriate, because they would lose the opportunity to profit from this weakening. Their hedge strategy should follow for an upside potential to match their viewpoint. Therefore, they should purchase sterling call options, paying a premium of:5,000,000 STG x 0.0176 = 88,000 STG.If the dollar strengthens against the pound, the firm allows the option to expire, and buys sterling in the spot market at a cheaper price than they would have paid for a forward contract; otherwise, the sterling calls protect against unfavorable depreciation of the dollar.Because the fund manager is uncertain when he will sell the bonds, he requires a hedge which will allow flexibility as to the exercise date. Thus, options are the best instrument for him to use. He can buy A$ puts to lock in a floor of 0.72 A$/$. Since he is willing to forego any further currency appreciation, he can sell A$ calls with a strike price of 0.8025 A$/$ to defray the cost of his hedge (in fact he earns a net premium of A$ 100,000,000 x (0.007234 –0.007211) = A$ 2,300), while knowing that he can’t receive less than 0.72 A$/$ when redeeming his investment, and can benefit from a small appreciation of the A$.Example #3:Problem: Hedge principal denominated in A$ into US$.

The German company is bidding on a contract which they cannot be certain of winning. Thus, the need to execute a currency transaction is similarly uncertain, and using a forward or futures asa hedge is inappropriate, because it would force them to perform even if they do not win the contract.Using a sterling put option as a hedge for this transaction makes the most sense. For a premium of:12 million STG x 0.0161 = 193,200 STG,they can assure themselves that adverse movements in the pound sterling exchange rate will not diminish the profitability of the project (and hence the feasibility of their bid), while at the same time allowing the potential for gains from sterling appreciation.5. Since AMC in concerned about the adverse effects that a strengthening of the dollar would have on its business, we need to create a situation in which it will profit from such an appreciation. Purchasing a yen put or a dollar call will achieve this objective. The data in Exhibit 1, row 7 represent a 10 percent appreciation of the dollar (128.15 strike vs. 116.5 forward rate) and can be used to hedge against a similar appreciation of the dollar.For every million yen of hedging, the cost would be:Yen 100,000,000 x 0.000127 = 127 Yen.To determine the breakeven point, we need to compute the value of this option if the dollar appreciated 10 percent (spot rose to 128.15), and subtract from it the premium we paid. This profit would be compared with the profit earned on five to 10 percent of AMC’s sales (which would be lost as a result of the dollar appreciation). The number of options to be purchased which would equalize these two quantities would represent the breakeven point.Example #5:Hedge the economic cost of the depreciating Yen to AMC.If we assume that AMC sales fall in direct proportion to depreciation in the yen (i.e., a 10 percent decline in yen and 10 percent decline in sales), then we can hedge the full valu e of AMC’s sales. I have assumed $100 million in sales.1) Buy yen puts# contracts needed = Expected Sales *Current ¥/$ Rate / Contract size9600 = ($100,000,000)(120¥/$) / ¥1,250,0002) Total Cost = (# contracts)(contract size)(premium)$1,524,000 = (9600)( ¥1,250,000)($0.0001275/¥)3) Floor rate = Exercise – Premium128.1499¥/$ = 128.15¥/$ - $1,524,000/12,000,000,000¥4) The payoff changes depending on the level of the ¥/$ rate.

CHAPTER 8
QUESTION
1.你会如何定义交易风险暴露？它与经济风险暴露有什么不同？
Answer：交易风险暴露是在交易结算时，国内公司合同中的资金流动的货币价值是以外币标价，由于外汇汇率变化而引起的风险。
（我来打个比方：其实就是以外币计值的交易，折合成本币价值时的不确定性而带来的风险）。
不同于经济风险暴露，交易暴露更加定义明确并且是短期的。
2. 讨论并比较使用远期合约与使用货币市场工具对交易风险暴露的套期保值。
在何种情况下两者效果相同？
A：使用远期合约对交易风险暴露进行套期保值是通过购买或者卖出外币的应收款或者应付款。
另一方面，货币市场工具的套期保值是通过借入或者外租当期市场价值的外币然后抵补应付账款或应收账款（书上的原文太难用中文解释了，我打个比方：货币市场套期保值的内容包括利用不同货币的利率之差进行保值和进行货币互换。
例如公司可以借入一种货币A，然后换成另外一种货币B进行投资，债务到期后，再兑换成原借入的货币A还款）。
假如利率平价是存在的话，那么这两种套期保值方法的效果是相同的。
3.讨论并比较通过远期合约与期权合约进行套期保值的成本。
A：并不能预先知道通过远期合约进行套期保值的成本。
然而，在期权合约进行套期保值的情况下，要进行套期保值必须为合同预先支付额外费用。
远期合约套期保值的费用可能在他们后悔做了远期合约保值的决定的之前就被知道。
4.作为一种套期保值的工具，货币期权合约与远期合约相比有哪些优点？
A：使用期权合约的主要优势是能让进行套期保值的人当他们留意和意识到未来利率变化的时候，能够决定是否运用期权合约进行套期保值。
如此一来，期权合约就提供了套期保值，在使用远期合约收到损失让你后悔之前。
进行套期保值的人就能在保持潜在的积极因素下避免了消极的风险。
5.假设你们公司购买欧元看跌期权来管理一项与该外币应收款相关的外汇风险暴露。
在这种情况下，可以说你们公司对这个应收款进行了保险。
请解释为什么可以这样理解。
A：在这种情况下，你的公司预先知道了他会收到一个确切的最小化金额，无论发生什么美元和欧元之间的汇率发生了什么样的变化。
并且，如果欧元升值，你的公司将从中受益。
6.最近对美国公司汇率风险管理实务的调查显示，许多美国公司并不进行套期保值。
你如何看待这一调查结果？
A：这其中可能会有许多方面的原因。
第一，许多公司会感觉到他们并不一定会暴露汇率风险因为他们产品的分散化，以及他们产品所在的分散的市场，等等。
第二，许多公司可能会采用自我保险的方法去抵抗汇率风险。
第三，许多公司会觉得股东他们自身能够分散汇率风险，提供企业的风险管理是多余的。
7.公司应不应该套期保值？为什么？
A：在一个完美的资本市场，公司也许不需要套期保值汇率风险。
但是，假如市场并不完美，
公司就能够通过套期保值增加他们的价值。
第一，假如管理者比股东更加了解公司的暴露，这个公司，而不是股东们，就需要套期保值。
第二，公司能够在低成本下进行套期保值。
第三，如果违约成本是重要的，企业的套期保值也同样重要，因为它能够减少违约的可能性。
第四，假如公司面对增长的赋税，那它将通过套期保值来减少纳税额，这将稳固公司的收入。
8.举例说明套期保值对公司纳税额的可能影响。
A:你可以使用一个类似于本章当中的例子。
9.解释或有风险暴露，并讨论使用货币期权来管理此类货币风险暴露的优点。
A：公司会遭遇一种情况，在这种情形下他们可能或不可能面对货币风险暴露。
在这种情况中，公司需要期权，而不是债券，去买入或者卖出他们可能或者不可能接受或者不得不支付的外国汇率。
假如公司要么采用远期合约来套期保值，要么不采取套期保值，那么他们就会面对确切的货币风险暴露。
10.解释交叉套期保值交易并讨论影响其有效性的因素。
A：交叉套期保值通过持仓其他资产来牵涉到套期保值在资产中的一个的位置。
交叉套期保值的影响将会建立在增强并且稳固两种资产之间的关系。
PROBLEMS
1.Cray研究所赊销给德国Max Planck研究所一台超级计算机，6个月后应收1000万欧元。
目前，6个月的远期汇率是XXX（图中的那个数字，我打不出来），而Cray研究所的外汇顾问预测6个月后的即期汇率是XXX（图中数字。
）
（1）使用远期合约套期保值的预期损益是多少？
（2）如果你是Cray研究所的财务经理，你会建议对这笔欧元应收款进行套期保值吗？为什么？
（3）假设外汇专家预测，未来的即期汇率将与今天报出的远期汇率相同，在这种情况下，你会建议套期保值吗？为什么？
（4）分别说明在期权和远期合约套期保值下，支付该笔瑞士法郎应付款的预期美元成本将如何随未来即期汇率的变化而变化。
解答：
（1）预期损益为：（图中数据）
（2）我会建议进行套期保值。
因为这能够使Cray研究所能通过50万美元的损益来增加预期美元收据，并且能够避免汇率风险。
（3）由于Cray研究所能够不用牺牲美元收据就能够规避汇率风险，我仍然会建议套期保值。
（4）目前，套期保值通过远期合约涉及了一项预期损失：-700000美元是由于10000000美元的汇率由（1.10上升到1.17）。

套期保值的选择严格意义上是由公司在一定程度上的规避心理决定的。
