Last section, 3 chapters on Foreign Exchange Exposure and Management. Chapter 12 covers one type of foreign exchange risk and discusses risk management techniques for Economic Exposure - the extent to which the value of the firm will affected by exchange rate uncertainty. We discuss how to measure economic exposure, what determines it, and how to manage and hedge economic exposure. Changes in ex-rates can affect a firm's: a) Balance Sheet and b) Income Statement.
Even a purely domestic firm, using only domestic parts (no imports), selling only in the domestic market (no exports), all AR and AP in local currency, etc., will be affected by changes in ex-rates. How???
Point: As business becomes increasingly global, exchange rate changes (volatility) become more important, even for a purely domestic firm operating in a global market. Firms have to pay more attention to exchange rate risk, and devise hedging strategies to manage and control currency risk.
See WSJ article on p. 286 for examples of how the 37% depreciation of the Mexican peso affected U.S. and Mexican companies in 1995.
Example: Dollar depreciated against the Yen in the late 1980s. Affected the competitive position of Japanese automakers selling vehicles in U.S., since they would have to raise dollar prices to maintain profitability in Yen. If the market is extremely competitive, that may not be possible without losing market share. Either way, profits probably fall. On the other hand, the fall in the dollar helped import-competing U.S. car makers, made them more competitive.
Dollar appreciated during the early 1980s, hit an all-time high in 1985, helping Japanese automakers, hurt import-competing U.S. companies. Japanese car makers could lower the dollar price of cars sold in the U.S., and still receive the same amount of Yen as before. The dollar has depreciated by 10% against most major currencies (20% against the Euro) over the last year, which has had a major effect on many U.S. and foreign businesses.
These examples illustrate the effects of changes in ex-rates on a firm's operating CFs, by affecting their competitive position, increasing or decreasing SLS revenues, COGS, input prices, operating profits, market share, share price, market value, etc., i.e. Economic Exposure.
Currency fluctuations also affect a firm's Balance Sheet by changing the value of the firm's assets and liabilities, another type of Economic Exposure. See Exhibit 12.2 on p. 285.
Example: Laker Airways, a British airline, pioneered the mass-market, high-volume, no-frills, low-fare air travel in the early 1980s. It borrowed heavily in dollars to buy airplanes (making fixed payments in $), but received more than half its revenue in British pounds. The $ appreciated in the early 1980s, peaked in 1985, and the pound was depreciating, dramatically increasing the debt burden of Laker Airways, forcing it into bankruptcy. Illustrates how serious currency risk can be. Other less extreme examples are in WSJ article, p. 286.
Economic Exposure depends on the unique characteristics of an industry and the individual characteristics of an individual firm. One way to measure Economic Exposure for an industry is to calculate the Forex Beta, see Exhibit 12.1, p. 283.
Market Beta is calculated as: Ri = a + β (Rm) + ei, where Ri is the monthly return on an industry portfolio of Fortune 500 companies, and Rm is the monthly market return (S&P500). Market betas range from .310 (Mining and crude oil) to 1.613 (transportation equipment). All betas are significant at the 1% level.
Forex Beta is calculated as: Ri = a + β (S) + ei, where S is the monthly dollar exchange rate index. A positive (negative) Forex Beta means that when the dollar appreciates the stock returns goes up (down). Of the 25 industries, 10 had a statistically significant (10% level or higher, noted by *) Forex Beta: 6 pos. Betas and 4 neg. betas.
Positive Forex Betas: Electronics, Furniture, Metals, Motor Vehicles and Parts, Textiles, Transportation. Dollar appreciates, stock prices go up. What might they have in common???
Negative Forex Betas: Petroleum Refining, Pharmaceuticals,
Science/Photo Equipment, Tobacco. Dollar depreciates, foreign currency
appreciates, stock prices go up. What might they have in common???
THREE TYPES OF FOREIGN EXCHANGE EXPOSURE FOR MNCs
1. Economic Exposure - Extent to which a firm's market value (in dollars) is sensitive to unexpected changes in foreign currency. Currency fluctuations affect the value of the firms CFs, Income Statement and Balance Sheet by altering its competitive position.
2. Transaction Exposure - Short term economic exposure (Ch. 13). Change in a firm's financial position due to the effect that changes in exchange rates have on a firm's contracts to either receive or pay a fixed amount of a foreign currency in the future. Currency risk exposure from changes in ex-rates that take place from the inception of a contract (denominated in foreign currency) and the settlement of the contract. Fixed price contracting (pay or receive Yen or Euro) in a world of ex-rate volatility leads to transaction exposure. Example: U.S. company pays €1m in 3 months, or receives €1m in 3 months.
3. Translation Exposure - change in a firm's financial position when the firm's consolidated financial statements are affected by currency changes. Example: GM sells cars in 200 countries and produces cars in 50 countries. Translation involves converting financial statements of foreign subsidiaries from the local currency to the home currency.

HOW TO MEASURE ECONOMIC EXPOSURE
Potential currency risk (unpredictable, random changes in ex-rates) is not the same as Currency Exposure, which is the firm's actual exposure to currency risk. If a company is hedged properly it might be insulated from currency risk and face no actual currency exposure. Example: U.S. company enters into an agreement to either receive $s (for exports) or pay $ (for imports), essentially transferring the currency exposure to the foreign company.
Example: You own foreign real estate, office building in U.K., in which case you may not face currency exposure. Reason: assume that changes in the pound are directly related to British inflation and British asset values for real assets. Over a given period, Pound depreciates by 4%/year against the dollar, UK inflation is 4% higher than U.S., British real estate appreciates at the rate of inflation (4%), insulating and protecting you against the pound falling. Dollar value of the asset is insensitive to ex-rate changes. You have no actual currency exposure, even though currency risk still exists.
Example: Fixed income security, British bond, with payments in BPs. Your investment CFs are now fixed in BPs, making them highly sensitive to changes in the value of the Pound. The dollar value of your income and asset value will fluctuate, and you now have unprotected currency exposure.
For a firm, Currency Exposure is measured by the sensitivity
of the firm's: a) Balance Sheet, and b) Operating CFs to random changes in
the ex-rate. See Exhibit 12.2 on p. 285.
ASSET EXPOSURE MEASUREMENT (SKIP)
Example: Assume a U.S. company or investor has a U.K. asset that fluctuates in local currency under three scenarios. If we can quantify the possible changes in ex-rates, the value of the asset in pounds and the value of the asset in dollars, we can calculate the exact Exposure Coefficient (beta) that will then determine the exact foreign currency amount that should be hedged, to minimize (or eliminate) currency exposure (risk).
Formula: P = a + β (S) + e, P* is the local currency price in BPs, S is the $/£ exchange rate, and P is dollar price of the foreign asset measure by: P = S x P*. See p. 285.
Three possible outcomes for S (spot rate) with equal (1/3) probability: $1.40/£, $1.50/£ and $1.60/£ for Case 1, Case 2 and Case 3. Each case makes a different assumption about the relationship between changes in the £, changed in P* and changes in the dollar value of the British asset.
Case 2 - Like the real estate case from before. If the pound depreciates (appreciates) by 6%, the pound value of the asset goes up (down) by 6%, resulting in a dollar value of $1400 in each outcome. In this case, Beta (exposure coefficient) = 0, meaning that there is no currency exposure, a perfectly hedged position.
Case 3 - Like owning a British bond, you get P* = £1000 in every state of the world, regardless of what happens to S. In that case, your Beta (exposure coefficient) = £1000, indicating that your exposure to currency risk is in the amount of £1000, and that represents the amount of foreign currency that you should hedge.
Exposure Coefficient = exact amount of foreign exchange to hedge to either eliminate or minimize currency exposure. In Case 2, you would hedge 0 and in Case 3 you would hedge £1000.
Case 1 - Similar to Case 3, except that now the
dollar price of the British asset changes by MORE than the change in the
pound. Starting with the middle case where S = $1.50 and P = $1500,
when S goes down to $1.40 (approx. -7%), P goes down by -9.3%. When
S = $1.60, pound goes up by about 7%, P goes up by 14%.
In Case 3, when the pound fell (rose) by 7%, P fell (rose)
by exactly 7%.
Exposure Coefficient (Beta) is £1700, meaning that the optimal hedge is that amount. However, since P does not change 1-for-1 with S, there is no way to completely eliminate currency exposure. Assume that one year F = $1.50, and you hedge exactly £1700, and that the future spot rate is going to be either $1.4, $1.5 or $1.6 with equal probabilities. You sell £1700 forward at F = $1.50, so your profits/loss from the hedge will be either:
1700 (1.50 - 1.60) = -$170 (pound appreciates)
1700 (1.50 - 1.50) = 0
1700 (1.50 - 1.40) = +$170 (pound depreciates)
See page 320, Exhibit 12.4. Under this optimal hedge, the dollar price of your British asset in one year will be either $1542, 1500 or $1542, with equal probability (expected value = $1528, with a variance of 392). If you hedged some other amount, e.g. £1500 or £1900 instead of 1700, the expected value would the same ($1528), but the variance would be 658, which is > 392.
Under Case 3 (fixed income), you can construct a perfect hedge since the CFs are certain, and the dollar value of the asset moves in a predictable and certain way with the changes in the ex-rate. You will receive $1500 in cash no matter what happens to the exchange rate.
Point: When the CFs are uncertain and/or when the dollar value of the foreign asset does not change in value in proportion to changes in the exchange rate, even the optimal hedge does NOT completely eliminate currency exposure.
Example: think of trying to hedge currency exposure
when owning a foreign stock versus owning a foreign bond over a 5 year
holding period.
OPERATING EXPOSURE
Firm's face: 1) Balance Sheet Exposure (or asset exposure) from the effect ex-rate changes have on AP, AR, INV, Loans in foreign currency, Investments (CDs) in foreign banks, etc. and 2) Operating Exposure - extent to which a firms operating CFs are affected by changes in ex-rates.
ILLUSTRATION, page 289. Albion Computers, a British subsidiary of a U.S. MNC, manufactures and sells PCs in U.K. market. Albion buys Intel microprocessors from the U.S. @ $512 as an imported input. Current S = $1.60 / £, so the cost in pounds is £320 ($512 / $1.60/£). It also buys locally sourced inputs @£330, for a total input cost of £650 per PC (£320 + £330). See projected CF statement in Exhibit 12.6 for the next year, Benchmark Case.
Operating CFs in Pounds = £7.25m
Operating CFs in dollars (@ S = $1.60) = $11.6m
Now consider the effect on CFs if the Pound depreciates
to $1.40/£. There are two possible effects:
1) Conversion Effect - without any changes at all in selling price (P), or number of units sold (Q), the operating CFs will be lower both in Pounds and Dollars since the price of the imported input is higher.
2) Competitive Effect - The firm's competitive position may worsen if the firm has to raise price to try to cover the higher pound cost of the imported input - it will lose some customers since it is facing a downward sloping demand curve for its products.
The Conversion Effect is illustrated on page 291, Exhibit 12.7, Case 1. Nothing changes (Q, FC, DEP, Taxes) except that the pound cost of the Intel microprocessor goes from £320 to £366, a 14% increase. Operating CFs go from £7.25m to £6.1m in pounds and from $11.6m to $8.54m, a 26% decrease.
Case 2 - Flawed? Assumptions: Albion raises PC prices from £1000 to £1143, a 14.3% increase and doesn't lose any business, Q = 50,000. CFs actually go up???
Case 3 - P, Q, locally sourced input price and imported input price ALL change, illustrating the Competitive Effect. Assume that inflation in UK is 8%, consistent with the depreciation of the pound. P goes up by 8% to £1080, and local inputs go up by 8% from £330 to £356. Imported price is £366, for total VC of £722/unit. Market is competitive, firm faces elastic demand curve for its PCs , so the 8% P increase leads to a 20% decrease in Qd, from 50,000 to 40,000. See page 291, Exhibit 12.9, Case 3 for a CF statement. Pound CFs = £5.66m and dollar CFs = $7.924m, a 32% decrease.
Assuming that the pound depreciation would affect CFs for 4 years, and assuming a discount rate of 15%, the PV of the CFs over 4 years is presented in Exhibit 12.10 on page 292. Using the benchmark case for comparison, we can calculate the Gain/Loss in Operating CFs from the change in the pound. Case 1: -$8.7m (conversion effect) and Case 3: -$10.5m.(competitive effect).
Point: Operating Exposure can be very significant.
DETERMINANTS OF OPERATING EXPOSURE
Operating Exposure is determined by: 1) the structure of the markets for: a) the firm's inputs (labor, materials) and b) the firm's products. Input market and Product Market (Retail).
2) The firm's ability to offset exchange rate changes by adjusting its markets, product mix, and sourcing.
Given that: Profit = Retail Price - Input Cost, the General Rule is that a firm has operating exposure when either its Price or Cost is sensitive to exchange rate changes, but NOT both. If both Price and Cost are equally sensitive, or if neither Price nor Cost are sensitive, then the firm has no major operating exposure.
Examples: Ford Mexicana (subsidiary of FMC in Mexico), imports U.S. Fords and sells in Mexico. Assume Peso depreciates. Two scenarios:
a) Ford Mexicana competes against Mexican car makers (whose peso costs did NOT rise) in a competitive market for cars, parts and service. Demand is highly elastic, price sensitive. Ford Mexicana's peso cost of imported U.S. Fords has gone up, but it cannot pass on the higher cost in the form of higher peso prices for its cars without losing market share. It is at a competitive disadvantage. Ford Mexicana's Cost is sensitive to ex-rate changes, but its price is not. Profit margins will be squeezed, reflecting the operating exposure.
b) There are no Mexican automakers, and Ford Mexicana faces only import competition from other U.S. carmakers - GM and Chrysler. When peso depreciates, all firms will charge higher peso prices in Mexico, offsetting some or all of the increased costs, maintaining the profit margins per car in dollars. There is less operating exposure under this scenario compared to the first scenario. Why might profits fall? What does profits depend on?
Ford Mexicana's operating exposure is also influenced by its ability to source parts, materials and even production locally in Mexico. If it can shift sourcing of parts, and even some (or all) production to Mexico, more of its costs will be in pesos, making the firm less exposed to changes in the dollar and peso. Firm's flexibility regarding production locations, sourcing, and hedging determines the operating exposure to exchange risk.
Note: If PPP holds perfectly, then the firm may not have operating exposure. Example: Inflation in US is 4% and inflation in Mexico is 15%. According to PPP, the $ (peso) should appreciate (depreciate) by 11%. Assume that domestic car prices rise at the inflation rate. Mexican car prices rise by 15%, U.S. car prices by 4%. In this case the peso price of Ford cars in Mexico rise by 15%, 4% because of U.S. inflation raising the dollar price of cars, and 11% because of the peso depreciation (dollar appreciation). Ford does not have direct operating exposure in this case since prices rise in Mexico for both domestic (Mexican) cars, and imported (U.S.) cars, each by 15%.
However, if PPP does not hold (which is common), then
Ford could have operating exposure. If dollar appreciates by MORE
than 11%, (peso depreciates by MORE than 11%), then the peso price of Fords in Mexico would rise by more than
15%, affecting Ford's competitive position.
Relative inflation rates are the same as above (4% US, 15% Mexico), but peso
depreciates by more than the difference (11%) in inflation rates, e.g., by 14%.
Now imported Fords increase in Mexico by 4% + 14% = 18%, which is higher than
the 15% increase in the cost of Mexican cars.
Strategies for dealing with unfavorable ex-rate shocks. Two extreme cases: 1) Increase selling price to exactly offset the change in ex-rate (Complete pass-through), 2) Maintain selling price, and fully absorb the currency shock (No pass-through). Under what market conditions (industry structure, competition, company size, product differentiation, etc.) would each case apply? The most typical strategy is a combination of the two extreme cases (Partial pass-through). See Exhibit 12.11 on p. 294, 1=Complete pass-through, 0=No pass-through. Range is from .08 to .88, Average pass-through is .4205. For a 10% change in ex-rate, firms would change prices by 4.2% on average.
MANAGING OPERATING EXPOSURE
In an increasingly globalized economy, firms need to consider
operating exposure as part of long-term strategic planning. Managing
operating exposure in not a short-term issue, but a long-term issue since
it involves long-term issues like production locations, sourcing, long-term debt,
etc. With sales, sourcing, production, partnerships, and joint ventures,
occurring in an increasingly global context, firms have to consider the
effects of ex-rate changes on their CFs, balance sheet, etc. Strategies
for managing operating exposure:
OPERATIONAL HEDGING
1. Selecting Low-Cost Production Sites. When domestic currency is strong (foreign currencies weak), a domestic firm selling (exporting) products overseas will be a competitive disadvantage, e.g., U.S. manufacturers/exporters in the mid-1980s (strong dollar), Japan in the late 80s and 90s (strong Yen).
See page 295, WSJ article about Toyota shifting production to U.S. because the strong Yen (weak dollar) weakened their competitive position. Subaru, Isuzu, Mazda, Honda, Nissan, Toyota, BMW, and Mercedes have all shifted production to U.S. and Mexico (VW). U.S. has shifted production to Mexico in auto industry and other industries. Nissan has plants in U.S., Japan and Mexico, giving it flexibility to shift production in response to changes in ex-rates. Example: Yen appreciated to the dollar in 1990s, dollar appreciated to the peso. Nissan shifted production to U.S. and Mexico to serve the U.S. market.
Possible disadvantage: If there are significant economies of scale in manufacturing, spreading production over three smaller sites may not achieve the same cost efficiencies as one large factory.
2. Flexible Sourcing Policy. Even if all production is domestic, the firm can take advantage of changes in ex-rates if it has flexibility in sourcing. Example: When U.S. dollar is strong and foreign currencies depreciate, firm can take advantage by sourcing to those countries with weak currencies. Examples: U.S. and Japanese companies buying from Mexico, Thailand, Indonesia, Brazil, etc. Flexible sourcing includes foreign labor as well as foreign parts and raw materials. Hire low-cost foreign workers instead of high-cost domestic workers. Example: Japan Airlines hires foreign crews to stay competitive when the Yen is strong instead of domestic crews.
3. Diversification of the Market. Diversify by: a) selling the same product in more than one country, and b) selling several different product lines in more than one foreign market. As long as ex-rates don't move together perfectly against the dollar, and as long as ex-rates don't affect each product line the same, the diversification will mitigate operating exposure to currency risk. Example: GE diversifies by selling electric motors in Germany and Mexico (peso may depreciate when euro appreciates, SLS go down in ______ and up in _______), and gas generators in Thailand and Brazil.
4. R&D Efforts and Product Differentiation.
R&D can lead to increased production efficiency/productivity, which
can make the firm more profitable and less exposed to operating exposure.
Also, if the firm can developed highly specialized, differentiated products,
e.g. leading to a patent, the demand for the firm's products will be more
inelastic, less sensitive to ex-rate risk. Example: If a firm
produces
a homogenous, standardized commodity like steel, or wheat, or oil, demand
will be very elastic - lots of substitutes. If a firm produces a
specialized, differentiated product like a pharmaceutical product that
no one else produces, the demand will be relatively inelastic, less sensitive
to currency risk. Harley-Davidsons, Steinway pianos, Volvo, etc. all have
unique product identities and niche markets.
FINANCIAL HEDGING
5. Currency futures, swaps, options, forward contracts can be used to stabilize operating CFs. Or firm can borrow or lend in a foreign currency. Financial hedging may be a more cost-effective strategy than operational hedging for many firms since it doesn't involve major redeployment of resources like building factories in other countries.
Example: U.S. manufacturer exports textile machinery to Europe, and also issues debt in Germany (in Euros). What if dollar strengthens? ________________ Weakens? ___________________________.
Mini-Case - Merck, page 296. U.S. MNC with operations in 100 countries, 40% of assets and 50% of SLS overseas. Merck faces currency mismatch because sales are in foreign currency and costs are mostly in dollars (R&D in U.S.). Profits are sensitive to currency changes: Profits ($) = Price (£, €, ¥) - Cost ($). What are they worried about?
Merck considered shifting production overseas, redeploying resources to minimize currency risk (operational hedging), but decided it was impractical and not cost-effective. Therefore, it decided to use financial hedging - currency futures, options, forward contracts, etc. Process of strategic planning:
1. Forecast CFs and future ex-rates for 5 years to determine the exposure.
2. Merck determined that its currency mismatch (SLS in foreign currency, COGS in $) and currency volatility exposed the company to significant ex-rate risk. To remain competitive and justify continuing to spend lots of money on R&D, it decided to use financial hedging to control and manage risk. What was Merck worried about?
3. Considered options and futures. Decided on buying put options as a way to buy insurance (premium cost) against DM/£/¥ falling but still be able to profit if the dollar continued to depreciate against major currencies. See diagram on board.
Merck decided to 1) use long term options rather than short term 2) only use a partial hedge and self-insure the rest. See Exhibit 12.12 on p. 298. Merck lowered risk and raised expected CFs by hedging.
