CHAPTER 1GLOBALIZATION AND THE MULTINATIONAL FIRMSUGGESTED ANSWERS TO END—OF-CHAPTER QUESTIONS QUESTIONS1 。

Why is it important to study international financial management？Answer: We are now living in a world where all the major economic functions, i.e.，consumption，production, and investment，are highly globalized. It is thus essential for financial managers to fully understand vital international dimensions of financial management. This global shift is in marked contrast to a situation that existed when the authors of this book were learning finance some twenty years ago. At that time, most professors customarily (and safely, to some extent) ignored international aspects of finance 。

This mode of operation has become untenable since then.2. How is international financial management different from domestic financial management？Answer ：There are three major dimensions that set apart international finance from domestic finance 。

CHAPTER 6 INTERNATIONAL PARITY RELATIONSHIPSSUGGESTED ANSWERS AND SOLUTIONS TO END-OF-CHAPTERQUESTIONS AND PROBLEMSQUESTIONS1。

Give a full definition of arbitrage。

Answer：Arbitrage can be defined as the act of simultaneously buying and selling the same or equivalent assets or commodities for the purpose of making certain, guaranteed profits。

2. Discuss the implications of the interest rate parity for the exchange rate determination。

Answer：Assuming that the forward exchange rate is roughly an unbiased predictor of the future spot rate, IRP can be written as:S = ［(1 + I£)/(1 + I$）］E[S t+1|I t］。

The exchange rate is thus determined by the relative interest rates，and the expected future spot rate，conditional on all the available information，I t, as of the present time。

One thus can say that expectation is self-fulfilling. Since the information set will be continuously updated as news hit the market, the exchange rate will exhibit a highly dynamic，random behavior.3. Explain the conditions under which the forward exchange rate will be an unbiased predictor of the future spot exchange rate.Answer: The forward exchange rate will be an unbiased predictor of the future spot rate if （I) the risk premium is insignificant and （ii) foreign exchange markets are informationally efficient。

How would you define transaction exposure How is it different from economic exposureAnswer: 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 resultAnswer: 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 contractAnswer: 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 resultAnswer: 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 notAnswer: 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 $€ and the foreign exchange advisor for Cray Research predicts that the spot rate is likely to be $€ in six months.(a) What is the expected gain/loss from the forward hedging(b) If you were the financial manager of Cray Research, would you recommend hedging this euro receivable Why or why not(c) Suppose the foreign exchange advisor predicts that the future spot rate will be the same as the forward exchange rate quoted today. Would you recommend hedging in this case Why or why not Solution: (a) Expected gain($) = 10,000,000 –= 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, .,250m/ = ￥245,700,So 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, = ￥250,000,000/105.The dollar cost of meeting this yen obligation is $2,340, 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 $SF and the three-month forward rate is $SF. You can buy the three-month call option on SF with the exercise rate of $SF for the premium of $ 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 $ = $250. At the expected future spot rate of $SF, which is less than the exercise price, you don’t expect to exercise options. Rather, you expect to buy Swiss franc at $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 $, ., $3,.(b) $3,150 = (.63)(5,000).(c) $3,150 = 5,000x + , where x represents the break-even future spot rate. Solving for x, we obtain x = $SF. Note that at the break-even future spot rate, options will not be exercised.(d) If the Swiss franc appreciates beyond $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, = $3,200 + $.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 €20million which is payable in one year. The current spot exchange rate is $€ and the one -year forward rateis $€. The annual interest rate is % in the U.S. and % 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 methodsSolution: (a) In the case of forward hedge, the future dollar proceeds will be (20,000,000) = $22,000,000. In the case of money market hedge (MMH), the firm has to first borrow the PV of its euro receivable, ., 20,000,000/ =€19,047,619. Then the firm should exchange this euro amount into dollars at the current spot rate to receive: (€19,047,619)($€) = $20,000,000, which can be in vested at the dollar interest rate for one year to yield:$20,000,000 = $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 = / = $€.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 $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 = $SF .(b) If the Swiss client chooses to pay $10,000, it will cost SF16,129 (=10,000/.62). Since the Swiss client has an option to pay SF15,000, it will choose to do so. The value of this option is obviously SF1,129 (=SF16,129-SF15,000).(c) Baltimore Machinery faces a contingent exposure in the sense that it may or may not receive SF15,000 in the future. The firm thus can hedge this exposure by buying a put option on SF15,000. 6. Princess Cruise Company (PCC) purchased a ship from Mitsubishi Heavy Industry. PCC owes Mitsubishi Heavy Industry 500 million yen in one year. The current spot rate is 124 yen per dollar and the one-year forward rate is 110 yen per dollar. The annual interest rate is 5% in Japan and 8% in the .$ Cost Options hedgeForward hedge$3,$3,1500 (strike price)$/SF$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/(124)= $4,147,465.(b) The option premium is: (.014/100)(500,000,000) = $70,000. Its future value will be $70,000 = $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,.The total expected cost will thus be $4,125,600, which is the sum of $75,600 and $4,050,000.(c) When t he 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 $€ and six-month forward exchange rate is $€ at the moment. Airbus can buy a six-month put option on . dollars with a strike price of €$ for a premium of € per . dollar. Currently, six-month interest rate is % in the euro zone and % 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 takeWhat would be the guaranteed euro proceeds from the American sale in this casec.If Airbus decides to hedge using put options on . 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 hedgeSolution:a. Airbus will sell $30 million for ward for €27,272,727 = ($30,000,000) / ($€).b. Airbus will borrow the present value of the dollar receivable, ., $29,126,214 = $30,000,000/, and then sell the dollar proceeds spot for euros: €27,739,251. This is the euro amount that Airbus is going to ke ep.c. Since the expected future spot rate is less than the strike price of the put option, ., €< €, Airbus expects to exercise the option and receive €28,500,000 = ($30,000,000)(€$). This is gross proceeds. Airbus spent €600,000 (=,000,000) upfront for the option and its future cost is equal to €615,000 = €600,000 x . Thus the net europroceeds 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, ., €$, or $€. Note that €28,432,732 is the future value of the proceeds under money market hedging:€28,432,732 = (€27,739,251) .Suggested solution for Mini Case: Chase Options, Inc.[See Chapter 13 for the case text]Chase Options, Inc.Hedging Foreign Currency Exposure Through Currency OptionsHarvey A. PoniachekI. Case SummaryThis case reviews the foreign exchange options market and hedging. It presents various international transactions that require currency options hedging strategies by the corporations involved. Seven transactions under a variety of circumstances are introduced that require hedging by currency options. The transactions involve hedging of dividend remittances, portfolio investment exposure, and strategic economic competitiveness. Market quotations are provided for options (and options hedging ratios), forwards, and interest rates for various maturities.II. Case Objective.The case introduces the student to the principles of currency options market and hedging strategies. The transactions are of various types that often confront companies that are involved in extensive international business or multinational corporations. The case induces students to acquire hands-on experience in addressing specific exposure and hedging concerns, including how to apply various market quotations, which hedging strategy is most suitable, and how to address exposure in foreign currency through cross hedging policies.III. Proposed Assignment Solution1. The company expects DM100 million in repatriated profits, and does not want the DM/$ exchange rate at which they convert those profits to rise above . They can hedge this exposure using DM put options with a strike price of . If the spot rate rises above , 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 = DM 1,640,000.With a strike price of DM/$, this would assure the U.S. company of receiving at least:DM 100,000,000 – DM 1,640,000 x (1 + x 272/360)= DM 98,254,544/ DM/$ = $57,796,791by exercising the option if the DM depreciated. Note that the proceeds from the repatriated profits are reduced by the premium paid, which is further adjusted by the interest foregone on this amount. However, if the DM were to appreciate relative to the dollar, the company would allow the option to expire, and enjoy greater dollar proceeds from this increase.Should forward contracts be used to hedge this exposure, the proceeds received would be:DM100,000,000/ DM/$ = $59,790,732,regardless of the movement of the DM/$ exchange rate. While this amount is almost $2 million more than that realized using option hedges above, there is no flexibility regarding the exercise date; if this date differs from that at which the repatriate profits are available, the company may be exposed to additional further current exposure. Further, there is no opportunity to enjoy any appreciation in the DM. If the company were to buy DM puts as above, and sell an equivalent amount in calls with strike price , the premium paid would be exactly offset by the premium received. This would assure that the exchange rate realized would fall between and . If the rate rises above , the company will exercise its put option, and if it fell below , the other party would use its call; for any rate in between, both options would expire worthless. The proceeds realized would then fall between:DM 100,00,000/ DM/$ = $60,716,454andDM 100,000,000/ DM/$ = $58,823,529.This would allow the company some upside potential, while guaranteeing proceeds at least $1 million greater than the minimum for simply buying a put as above.Buy/Sell OptionsDM/$SpotPut Payoff “Put”Profits Call Payoff“Call”Profits Net Profit(1,742,846) 0 1,742,846 60,716,454 60,716,454 (1,742,846) 0 1,742,846 60,716,454 60,716,454 (1,742,846) 0 1,742,846 60,716,454 60,716,454 (1,742,846) 0 1,742,846 60,716,454 60,716,454 (1,742,846) 0 1,742,846 60,716,454 60,716,454 (1,742,846) 60,606,061 1,742,846 0 60,606,061 (1,742,846) 60,240,964 1,742,846 0 60,240,964 (1,742,846) 59,880,240 1,742,846 0 59,880,240 (1,742,846) 59,523,810 1,742,846 0 59,523,810 (1,742,846) 59,171,598 1,742,846 0 59,171,598 (1,742,846) 58,823,529 1,742,846 0 58,823,529 (1,742,846) 58,823,529 1,742,846 0 58,823,529 (1,742,846) 58,823,529 1,742,846 0 58,823,529 (1,742,846) 58,823,529 1,742,846 0 58,823,529 (1,742,846) 58,823,529 1,742,846 0 58,823,529 (1,742,846) 58,823,529 1,742,846 0 58,823,529 (1,742,846) 58,823,529 1,742,846 0 58,823,529 (1,742,846) 58,823,529 1,742,846 0 58,823,529 (1,742,846) 58,823,529 1,742,846 0 58,823,529 (1,742,846) 58,823,529 1,742,846 0 58,823,529(1,742,846) 58,823,529 1,742,846 0 58,823,529 (1,742,846) 58,823,529 1,742,846 0 58,823,529 (1,742,846) 58,823,529 1,742,846 0 58,823,529 (1,742,846) 58,823,529 1,742,846 0 58,823,529 (1,742,846) 58,823,529 1,742,846 0 58,823,529 (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 = 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 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 = 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 strike vs. 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 = 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 , 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 ., 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)$1,524,000 = (9600)( ￥1,250,000)($￥)3) Floor rate = Exercise – Premium￥/$ = ￥/$ - $1,524,000/12,000,000,000￥4) The payoff changes depending on the level of the ￥/$ rate.

CHAPTER 9 MANAGEMENT OF ECONOMIC EXPOSURESUGGESTED ANSWERS AND SOLUTIONS TO END-OF-CHAPTERQUESTIONS AND PROBLEMSQUESTIONS1. How would you define economic exposure to exchange risk?Answer: Economic exposure can be defined as the possibility that the firm’s cash flows and thus its market value may be affected by the unexpected exchange rate changes.2. Explain the following statement: “Exposure is the regression coefficient.”Answer: Exposure to currency risk can be appropriately measured by th e sensitivity of the firm’s future cash flows and the market value to random changes in exchange rates. Statistically, this sensitivity can be estimated by the regression coefficient. Thus, exposure can be said to be the regression coefficient.3. Suppose that your company has an equity position in a French firm. Discuss the condition under which the dollar/franc exchange rate uncertainty does not constitute exchange exposure for your company.Answer: Mere changes in exchange rates do not necessarily constitute currency exposure. If the French franc value of the equity moves in the opposite direction as much as the dollar value of the franc changes, then the dollar value of the equity position will be insensitive to exchange rate movements. As a result, your company will not be exposed to currency risk.4. Explain the competitive and conversion effects of exchange rate changes on the firm’s operating cash flow.Answer: The competitive effect: exchange rate changes may affect operating cash flows by altering the firm’s competitive position.The conversion effect: A given operating cash flows in terms of a foreign currency will be converted into higher or lower dollar (home currency)amounts as the exchange rate changes.5. Discuss the determinants of operating exposure.Answer: The main determinants of a firm’s operating exposure are (1) the structure of the markets in which the firm sources its inputs, such as labor and materials, and sells its products, and (2) the firm’s ability to mitigate the effect of exchange rate changes by adjusting its markets, product mix, and sourcing.6. Discuss the implications of purchasing power parity for operating exposure.Answer: If the exchange rate changes are matched by the inflation rate differential between countries, firms’ competitive positions will not be altered by exchange rate changes. Firms are not subject to operating exposure.7. General Motors exports cars to Spain but the strong dollar against the peseta hurts sales of GM cars in Spain. In the Spanish market, GM faces competition from the Italian and French car makers, such as Fiat and Renault, whose currencies remain stable relative to the peseta. What kind of measures would you recommend so that GM can maintain its market share in Spain.Answer: Possible measures that GM can take include: (1) diversify the market; try to market the cars not just in Spain and other European countries but also in, say, Asia; (2) locate production facilities in Spain and source inputs locally; (3) locate production facilities, say, in Mexico where production costs are low and export to Spain from Mexico.8. What are the advantages and disadvantages of financial hedging of the firm’s operating exposure vis-à-vis operational hedges (such as relocating manufacturing site)?Answer: Financial hedging can be implemented quickly with relatively low costs, but it is difficult to hedge against long-term, real exposure with financial contracts. On the other hand, operational hedges are costly, time-consuming, and not easily reversible.9. Discuss the advantages and disadvantages of maintaining multiple manufacturing sites as a hedge against exchange rate exposure.Answer: To establish multiple manufacturing sites can be effective in managing exchange risk exposure, but it can be costly because the firm may not be able to take advantage of the economy of scale.10. Evaluate the following statement: “A firm can reduce its currency exposure by diversifying across different business lines.”Answer: Conglomerate expansion may be too costly as a means of hedging exchange risk exposure. Investment in a different line of business must be made based on its own merit.11. The exchange rate uncertainty may not necessarily mean that firms face exchange risk exposure. Explain why this may be the case.Answer: A firm can have a natural hedging position due to, for example, diversified markets, flexible sourcing capabilities, etc. In addition, to the extent that the PPP holds, nominal exchange rate changes do not influenc e firms’ competitive positions. Under these circumstances, firms do not need to worry about exchange risk exposure.PROBLEMS1. Suppose that you hold a piece of land in the City of London that you may want to sell in one year. As a U.S. resident, you are concerned with the dollar value of the land. Assume that, if the British economy booms in the future, the land will be worth £2,000 and one British pound will be worth $1.40. If the British economy slows down, on the other hand, the land will be worth less, i.e., £1,500, but the pound will be stronger, i.e., $1.50/£. You feel that the British economy will experience a boom with a 60% probability and a slow-down with a 40% probability.(a) Estimate your exposure b to the exchange risk.(b) Compute the variance of the dollar value of your property that is attributable to the exchange rate uncertainty.(c) Discuss how you can hedge your exchange risk exposure and also examine the consequences of hedging.Solution: (a) Let us compute the necessary parameter values:E(P) = (.6)($2800)+(.4)($2250) = $1680+$900 = $2,580E(S) = (.6)(1.40)+(.4)(1.5) = 0.84+0.60 = $1.44Var(S) = (.6)(1.40-1.44)2 + (.4)(1.50-1.44)2= .00096+.00144 = .0024.Cov(P,S) = (.6)(2800-2580)(1.4-1.44)+(.4)(2250-2580)(1.5-1.44)= -5.28-7.92 = -13.20b = Cov(P,S)/Var(S) = -13.20/.0024 = -£5,500.You have a negative exposure! As the pound gets stronger (weaker) against the dollar, the dollar value of your British holding goes down (up).(b) b2Var(S) = (-5500)2(.0024) =72,600($)2(c) Buy £5,500 forward. By doing so, you can eliminate the volatility of the dollar value of your British asset that is due to the exchange rate volatility.2. A U.S. firm holds an asset in France and faces the following scenario:In the above table, P* is the euro price of the asset held by the U.S. firm and P is the dollar price of the asset.(a) Compute the exchange exposure faced by the U.S. firm.(b) What is the variance of the dollar price of this asset if the U.S. firm remains unhedged against thisexposure?(c) If the U.S. firm hedges against this exposure using the forward contract, what is the variance of thedollar value of the hedged position?Solution: (a)E(S) = .25(1.20 +1.10+1.00+0.90) = $1.05/€E(P) = .25(1,800+1,540+1,300 +1,080) = $1,430Var(S) = .25[(1.20-1.05)2 +(1.10-1.05)2+(1.00-1.05)2+(0.90-1.05)2]= .0125Cov(P,S) = .25[(1,800-1,430)(1.20-1.05) + (1,540-1,430)(1.10-1.05)(1,300-1,430)(1.00-1.05) + (1,080-1,430)(0.90-1.05)]= 30b = Cov(P,S)/Var(S) = 30/0.0125 = €2,400.(b) Var(P) = .25[(1,800-1,430)2+(1,540-1,430)2+(1,300-1,430)2+(1,080-1,430)2]= 72,100($)2.(c) Var(P) - b2Var(S) = 72,100 - (2,400)2(0.0125) = 100($)2.This means that most of the volatility of the dollar value of the French asset can be removed by hedging exchange risk. The hedging can be achieved by selling €2,400 forward.MINI CASE: ECONOMIC EXPOSURE OF ALBION COMPUTERS PLCConsider Case 3 of Albion Computers PLC discussed in the chapter. Now, assume that the pound is expected to depreciate to $1.50 from the current level of $1.60 per pound. This implies that the pound cost of the imported part, i.e., Intel’s microprocessors, is £341 (=$512/$1.50). Other variables, such as the unit sales volume and the U.K. inflation rate, remain the same as in Case 3.(a) Compute the projected annual cash flow in dollars.(b) Compute the projected operating gains/losses over the four-year horizon as the discounted present value of change in cash flows, which is due to the pound depreciation, from the benchmark case presented in Exhibit 12.4.(c) What actions, if any, can Albion take to mitigate the projected operating losses due to the pound depreciation?Suggested Solution to Economic Exposure of Albion Computers PLCa) The projected annual cash flow can be computed as follows:______________________________________________________Sales (40,000 units at £1,080/unit) £43,200,000Variable costs (40,000 units at £697/unit) £27,880,000Fixed overhead costs 4,000,000Depreciation allowances 1,000,000Net profit before tax £15,315,000Income tax (50%) 7,657,500Profit after tax 7,657,500Add back depreciation 1,000,000Operating cash flow in pounds £8,657,500Operating cash flow in dollars $12,986,250______________________________________________________b) ______________________________________________________Benchmark CurrentVariables Case Case______________________________________________________Exchange rate ($/£) 1.60 1.50Unit variable cost (£) 650 697Unit sales price (£) 1,000 1,080Sales volume (units) 50,000 40,000Annual cash flow (£) 7,250,000 8,657,500Annual cash flow ($) 11,600,000 12,986,250Four-year present value ($) 33,118,000 37,076,946Operating gains/losses ($) 3,958,946______________________________________________________c) In this case, Albion actually can expect to realize exchange gains, rather than losses. This is mainly due to the fact that while the selling price appreciates by 8% in the U.K. market, the variable cost of imported input increased by about 6.25%. Albion may choose not to do anything.。

国际财务管理课后作业答案

《国际财务管理》章后练习题第一章【题1—1】某跨国公司A，2006年11月兼并某亏损国有企业B。

B企业兼并时账面净资产为500万元，2005年亏损100万元（以前年度无亏损），评估确认的价值为550万元。

经双方协商，A 跨国公司可以用以下两种方式兼并B企业。

甲方式：A公司以180万股和10万元人民币购买B企业（A公司股票市价为3元/股）；乙方式：A公司以150万股和100万元人民币购买B企业。

兼并后A公司股票市价3.1元/股。

A公司共有已发行的股票2000万股（面值为1元/股）。

假设兼并后B企业的股东在A公司中所占的股份以后年度不发生变化，兼并后A公司企业每年未弥补亏损前应纳税所得额为900万元，增值后的资产的平均折旧年限为5年，行业平均利润率为10%。

所得税税率为33%。

请计算方式两种发方式的差异。

【题1—1】答案（1）甲方式：B企业不需将转让所得缴纳所得税；B 企业2005年的亏损可以由A公司弥补。

A公司当年应缴所得税=（900-100）×33%=264万元，与合并前相比少缴33万元所得税，但每年必须为增加的股权支付股利。

（2）乙方式：由于支付的非股权额（100万元）大于股权面值的20%（30万元）。

所以，被兼并企业B应就转让所得缴纳所得税。

B企业应缴纳的所得税=（150 ×3 + 100- 500）×33% = 16.5（万元）B企业去年的亏损不能由A公司再弥补。

（3）A公司可按评估后的资产价值入帐,计提折旧,每年可减少所得税(550-500)/5×33%=3.3万元。

【题1—2】东方跨国公司有A、B、C、D四个下属公司，2006年四个公司计税所得额和所在国的所得税税率为：A公司：500万美元 33%B公司：400万美元 33%C公司：300万美元 24%D公司：-300万美元 15%东方公司的计税所得额为-100万美元，其所在地区的所得税税率为15%。

（2）乙方式：由于支付的非股权额（100万元）大于股权面值的20%（30万元）。

所以，被兼并企业B应就转让所得缴纳所得税。

B企业应缴纳的所得税=（150 ×3 + 100- 500）×33% = 16.5（万元）B企业去年的亏损不能由A公司再弥补。

（3）A公司可按评估后的资产价值入帐,计提折旧,每年可减少所得税(550-500)/5×33%=3.3万元。

请从税务角度选择成立子公司还是分公司？【题1—2】答案（1）若A、B、C、D为子公司A公司应纳所得税额=500×33%=165（万美元）B公司应纳所得税额=400×33%=132（万美元）C公司应纳所得税额=300×24%=72（万美元）D公司和总公司的亏损留作以后年度弥补。

东方跨国公司2006年度合计应纳所得税额=165+132+72=369（万美元）（2）若A、B、C、D为分公司分公司本身不独立核算，那么，各分支机构的年度计税所得额都要并入总机构缴纳所得税，其应纳所得税的计算为：500+400+300-300-100）×15%=120（万美元）企业合并纳税，一是各自之间的亏损可以弥补，二是由于总机构位于低税率地区，汇总纳税可以降低税率，节税249万美元（369-120）。

答案：【题2—3】某日伦敦外汇市场￡1＝HK$14.6756-94，3个月远期汇率点数248－256。

要求，根据远期报价点数计算远期汇率数。

【题2—3】答案：HK$14.6756＋0.0248＝HK$14.7004HK$14.6794＋0.0256＝HK$14.7050远期汇率报价点数为HK$14.7004-50【题2—4】某日，纽约市场1美元＝1.2130－45欧元，法兰克福市场1英镑＝1.5141－53欧元，伦敦市场1英镑＝1.3300－20美元。

套汇者拟用200万英镑进行间接套汇。

要求：分析该套汇者是否能通过套汇获得收益？如何进行套汇？如果进行套汇，计算其套汇收益（或损失）。

【题2—4】答案：（1）可以进行套汇交易。

因为：根据法兰克福市场与伦敦市场的汇率套算：美元与欧元的套算汇率为：€1.5153/￡÷$1.3300/￡＝€1.1393/$——假定欧元换英镑，再换成美元。

而：纽约市场美元换欧元汇率为：€1.2130/$。

存在汇率差。

（2）可以采用英镑——美元——欧元——英镑方式。

即：伦敦市场：英镑换美元：￡200×1.33＝$266（万元）纽约市场：美元换欧元：$266×1.213＝€322.658（万元）法兰克福市场：欧元换英镑：€322.658÷1.5153＝￡212.933413（万元）（3）套汇获利￡129 334.13。

【题3—3】答案：【题3—4】假设美国的5年期年利率为6%，瑞士法郎5年期年利率为4%，利率平价在5年内存在。

如果瑞士法郎的即期汇率为0.82美元。

要求计算：a.瑞士法郎5年期远期汇率升水或贴水。

b.用远期汇率预测法预测5年后瑞士法郎的即期汇率。

【题3—4】答案：（1）瑞士法郎5年期远期汇率升水。

（2）瑞士法郎5年期预期汇率＝$0.82/SFr×（1＋6%）5÷（1＋4%）5＝0.82×1.3382÷1.2167＝$0.90/SFr【题3—5】2006年9月1日，某跨国公司收到了摩根大通和高盛对未来6个月后人民币与美元汇率的预测，结果分别是￥7.66/$和￥7.74/$。

第四章【题4—1】法国某跨国公司预计在6月份（3个月后）有一笔150万的欧元应付账款，同月该公司有一笔美元收入，可以用于支付此笔应付账款。

已知欧元的即期汇率为$1.0450/€， 3个月远期汇率$1.0650/€。

公司担心欧元相对于美元的价值将继续上升，决定使用期货交易锁定美元成本。

请回答：（1）该公司应该购买还是出售3个月欧元期货合约？为什么？（2）该公司需要购买或者出售多少份欧元期货合约?（3）该公司6月份应该如何操作？（假定当时欧元的即期汇率是$1.0900/€，期货价格为$1.0950/€）（4）与不进行期货交易保值相比，公司可降低多少美元成本？【题4—1】答案：（1）预计未来欧元升值，为锁定美元成本，应该购买欧元期货合约；（2）公司需要购买欧元期货合约份数：€1 500 000÷€125 000/份＝12份（3）6月份公司应以$1.0950/€的价格出售12份欧元期货合约，轧平欧元期货头寸。

同时在即期市场上以$1.0900/€汇率出售已经收到的美元，买进150万的欧元，支付应付账款。

（4）如果不进行期货交易保值，公司在即期市场购买150万欧元的美元成本为：1 500 000×$1.0900/€＝$1 635 000进行期货交易保值，公司购买150万欧元的美元成本为：1 500 000×（$1.0900/€＋$1.0650/€－$1.0950/€）＝$1 590 000公司降低美元成本：$1 635 000－$1 590 000＝$45 000【题4—2】某公司正在考虑从费城交易所购买3个月期的英镑看涨期权合约，金额为￡250 000。

协定价格为$1.51/￡，期权费为每英镑0.03美元。

假定：目前的即期汇率为$1.48/￡，三个月远期汇率为$1.51/￡。

该公司预测三个月后即期汇率最高为$1.57/￡，最低为$1.44/￡，最可能的汇率是$1.52/￡。

要求：（1）计算盈亏平衡点价格。

（2）用图表表述该公司期权行使与否决策。

（3）计算在预测的范围内，该公司的收益或损失。

【题4—2】答案（1）盈亏平衡点价格＝$1.51/￡＋0.03＝$1.54/￡（2）该公司期权行使与否决策图。

（3-1）当即期外汇市场价格＝$1.57/￡，超过协定价格，行使期权，有收益。

计算如下收益＝￡250 000×（$1.57/￡－$1.54/￡）＝$7 500（3-2）当即期外汇市场价格＝$1.52/￡，高于协定价格，行使期权，有损失，损失低于期权费$7500。

计算如下：损失＝￡250 000×（$1.54/￡－$1.52/￡）＝$5 000（3-2）当即期外汇市场价格＝$1.44/￡，低于协定价格，放弃行使期权，损失期权费$7500。
