  1. International Project Evaluation and Real Options Global Financial Management Campbell R. Harvey Fuqua School of Business Duke University charvey@mail.duke.edu http://www.duke.edu/~charvey

  2. Overview • Topics in Capital Budgeting • Investments in international project • What are the cost of capital? • How do you assess risk and returns in foreign currencies? • Capital budgeting and stratetic decisions • Decision trees and real options

  3. Offshore Borrowing • Suppose you are an Australian wheat farmer and you want to borrow to expand your operations. • You intend to borrow 10 million AUD for 5 years. The spot rate is 0.8 AUD/CHF. • You face a rate of 12% in Australian Dollar-denominated loans. • A Swiss bank, however, will lend at 9% by way of Swiss Franc-denominated loans. • What should you do? • Borrow 10m AUD in Australia? • repay 10*(1.12)5 AUD in 5 years • Borrow 12.5m CHF, and convert into AUDs? • repay 12.5*(1.09)5 CHF in 5 years

  4. Offshore Borrowing • The question is whether 10(1.12)5 m AUD will be more than 12.5(1.09)5 m CHF. • Depends on the spot rate 5 years from now, which is uncertain. • Decide to hedge this risk using the forward market. • Suppose the 5-year forward rate is 0.91632 AUD/CHF. • Paying back the 12.5(1.09)5 m CHF will require: 12.5(1.09)5(0.91632) m AUD = 17.62 m AUD • But this is exactly what would have to be repaid under the AUD loan since: 10(1.12)5 m AUD = 17.62 m AUD. • Hence nothing has been gained by borrowing offshore! • Why does this work?

  5. Covered Interest Rate Parity • This equivalence always holds and is known as covered interest rate parity:

  6. Suppose the forward rate is 0.80 AUD/CHF: Borrow 1.25 CHF and convert to 1.00 AUD. Invest for 5 years at 12% yielding 1.00(1.12)5=1.76 AUD in 5 years. Convert to 1.76/0.8=2.20 CHF. Repay CHF loan with 1.25(1.09)5=1.92 CHF. The remaining 2.20-1.92=0.28 is an arbitrage profit. Suppose the forward rate is 1.00 AUD/CHF: Borrow 1.00 AUD and convert to 1.25 CHF. Invest for 5 years at 9% yielding 1.25(1.09)5=1.92 CHF in 5 years. Convert to 1.92(1.00)=1.92 AUD. Repay AUD loan with 1.00(1.12)5=1.76 AUD. The remaining 1.92-1.76=0.16 is an arbitrage profit. Proof By Arbitrage

  7. International Capital Budgeting • Arctis, a canadian manufacturer of heating equipment, considers building a plant in Japan. The plant would cost Yen1.3m to build and would produce cash flows of Yen200,000 for the next 7 years. Other data are: • Yen interest rate:2.9% • C$ interest rate: 8.75% • Spot rate: Yen/C$: 83.86 • Assumption: the investment is risk free • How should you calculate the NPV?

  8. Method I Step 1: Forecast cash flows in Yen Step 2: Discount at interest rate for Yen; gives NPV in Yen Step 3: Convert NPV in Yen into Canadian dollars at spot exchange rate, gives NPV in C$ Method II Step 1: Forecast cash flows in Yen Step 2: Convert cash flows into C$ using implied forward rate Step 3: Discount C$ cash flows using the interest rate for C$, gives NPV in C$. Two Ways of Calculating NPV

  9. Results for Two Methods Method I: Present value = -Yen 49,230 Method II: Present value = -C$ 590 = -Yen (590*83.86)=-Yen49,230 • Both methods yield the same result! • Why is this necessary?

  10. Alternative Exchange Rate Forecast • Suppose the corporate treasurer argues that the true value of the investment is understated, because the market is too pessimistic about the Yen • Assume the Yen appreciates 2.5% p. a. faster than anticipated by the market • Now the PV with Method II becomes C$ 976 or Yen 81,840 • Now the project looks profitable, should you take it?

  11. Capital Budgeting and Currency Speculation • Break down your project into two investments: 1. Borrow C$ 15.502 and convert them into Yen for Yen1.3m; • Zero-NPV project 2. Invest the proceeds into plant for heating equipment • Negative NPV (Yen -49,230). • Compare this with an alternative combination of two investments: 1. Borrow C$ 14.915 and convert them into Yen for Yen1.251m; 2. Invest the proceeds into a 7-year bond with repayment of 200. • Positive NPV of C$ 1,563 if optimistic treasurer is correct • Hence, investing in plant has two consequences: • Profit of C$ 1,563 on speculation on Yen • Loss of C$ 587 on plant • Net gain is 1,563-587=C$976

  12. SummaryInternational Capital Budgeting • There is no easy gain from offshore borrowing • Implication of covered interest rate parity • Use discount rate for relevant currency • It does not matter which one you take • Use consensus forecast of market • Don’t delude yourself by taking a “view” on exchange rates

  13. The Limitations of Simple NPV Aim: • Analyse risky projects under circumstances where uncertainty can be managed. Simple NPV-Analysis: • Treat investment as one-off decision: • Project stays constant; cannot be adapted. • Treat uncertainty as an exogenous factor Decision Trees and real options • Managers respond to risk-factors: • Integrate strategy and capital budgeting • What is the value of flexibility and responsiveness?

  14. Investment under Uncertainty:The Simple NPV Rule 0 1 2 ... T ... Period Revenue 120 120 ... 120 ... if Demand is high 50% Initial Investment I 50% Revenue if Demand 80 80 ... 80 ... is low Cost of Capital = 10% NPV = - I + 100/0.1 = 1000 - I Invest if I < 1000

  15. Investment under Uncertainty: Delay Strategy: Wait one Period Case 1: I > 800, do not invest if demand is low 0 1 2 ... T ... Period Revenue 0 - I 120 ... 120 ... if Demand is high 50% Demand 50% Revenue if Demand 0 ... 0 ... 0 0 is low 0.5 1200 - I 120 120 ( - I + + + ... ) = NPV = 1.1 1.12 1.1 2.2

  16. Investment under Uncertainty: Delay (2) Strategy: Wait one Period Case 2: I < 800, always invest 0 1 2 ... T ... Period Revenue 120 ... 120 ... if Demand 0 - I is high 50% Demand 50% Revenue if Demand 80 ... 80 ... 0 - I is low 1 1000 - I 100 100 ( - I + + + ... ) = NPV = 1.1 1.12 1.1 1.1

  17. Summary of Strategies Decision rule NPV (1) Simple NPV 1000 - I (2) Delay if I > 800 (3) Delay if I < 800 • Delay is never optimal if I < 800 • Delay is better than investing now if I > 833 • Investment is never optimal if I > 1200

  18. Comparison of both Strategies NPV I > 1200: Never invest 833 < I < 1200: Wait; invest if demand is high 1000 I < 833: Invest now 909 1000 - I (1000 - I)/1.1 Vertical distance = value of flexibility 181 (1200-I)/2.2 0 I 0 800 833 1000 1200

  19. Results of Comparison (1) 1 If 833 < I < 1000 Investment now has positive NPV = 1000 - I However: Waiting is optimal in order to see how uncertainty over demand resolves. • Benefits from waiting: receive information to avoid loss. • Costs of waititng: delay of receiving cash flows. Investment in positive NPV projects is not always optimal: the flexibility gained from waiting has a positive value. Note: Critical point is 833, not 800, why?

  20. Results of Comparison (2) 2 If 1000 < I < 1200 Investment now has negative NPV. However: The project should not be abandoned: if demand turns out high later, it has a positive NPV. Negative NPV-projects should be delayed, but not always be dismissed.

  21. Total NPV and Simple NPVIncorporating the Value of Flexibility • The project can be broken down into two components: • The investment possibility itself • Has a Simple NPV of 1000-I • The flexibility of the project from the option to delay investment • Value of Flexibility is: = Max (Value of investment later - Value of investing now, 0) • Total NPV is the value of the whole project: Total NPV = Simple NPV + Value of Flexibility • Investing immediately ignores that option of delay is valuable • Decisions must be based on total NPV The value of flexibility is never negative Total NPV leads always to the correct decision

  22. Compute the Value of Flexibility • If I<833, invest now, hence option to delay has no value. • If 1000>I>833, then: • Value of investing now = 1000 - I • Expected value of investing later is (1200-I)/2.2 • Value of flexility is then: So, with I=833, the value of flexibility is zero (why?), with I=1000 it increases to 91. • If 1200> I>1000, the value of flexibility is simply (1200-I)/2.2. • How does this change if the investment becomes more risky?

  23. How to Use Total NPV • Assume I=900>833, hence value of flexibility positive. • Value of following optimal strategy = Total NPV • Value of investing now = Simple NPV • Value of flexibility = 80/2.2=36.4 • Should you invest now? • Investing now gives 1000-900=100, • Simple NPV =100>0 • Investing later gives: • Total NPV = Simple NPV + Value of Flexibility = 100 + 36.4 = 136.4 • Total NPV > Simple NPV, therefore delay! • Deciding on the basis of Simple NPV ignores that investing now “kills the option”; • Base decision always on Total NPV!

  24. The Impact of Volatility • How does the value of flexibility depend on uncertainty? • Compare previous case with situation of more volatile prices: Revenue (High Demand) = 150 Revenue (Low Demand) = 50 Expected revenue is unchanged ( = 100). Volatility is higher.

  25. Flexibility in a Volatile Environment Value of Flexibility Prices 150/50 250 Prices 120/80 0 I 0 583 833 1000 1200 1500 Flexibility has a higher value in a more volatile environment

  26. The Option to Abandon Assume same scenario as before, but no option to delay Revenue (High Demand) = 120 Revenue (Low Demand) = 80 Investment outlay I = 1010 If there is no option to delay, NPV=1000-I=-10 • Do not invest! Assume assets have a scrap value: • At the end of the period: scrap value = 910 • After the first period: scrap value = 0

  27. The Option to Abandon High revenue state (120): • PV (Cash Flow) = 1200 > 910 • Continue after period 1! • Receive: 1200 + 120 in period 1 Low revenue state (80): • PV (Cash Flows) = 800 < 910 • Divest and abandon project in period 1! • Receive: 910 + 80 in period 1 With option to abandon, NPV=40 Invest: Option to abandon makes the project viable.

  28. The Value of InformationHow to value a test market Strategy D: - Introduce the product directly. - Receive the cash flows immediately. - If product is not accepted, launching costs are sunk. Strategy T: - Introduce the product on a test market before launching it for the whole market. - Launch the product only if it is accepted in the test market; costs for launching are only incurred in this case. - Receive cash flows later. Assumption: - The test market study gives you 100% reliable information about the acceptance of the product. Question: - How much are you willing to pay for a test market study?

  29. Value a Test MarketAn Example Example: Revenue if product is accepted: 10 Revenue if it is not accepted: 5 Both cases are equally likely. Cost of launching the product: 60 Discount rate = 10% Strategy D: Strategy T: Value of test market = 18.2 - 15 = 3.2

  30. Flexibility and Project Design • Many projects have built-in flexibility: • Options to contract or expand. • Possibility to abandon if the assets have values outside the project (secondary market). • Development opportunities: • Sequence of models of the same product. • Oil fields. • In many cases the project can be designed to be more flexible: • Leasing contracts. • Make or buy decisions. • Scale versus adaptability.

  31. Natural Resource Investments • Your company has a two year lease to extract copper from a deposit. • Contains 8 million pounds of copper. • 1-year development phase costs $1.25m immediately. • Extraction costs of 85 cents per pound would be paid to a contractor in advance when production begins • The rights to the copper would be sold at the spot price of copper one year from now. • Percentage price changes for copper are N(0.07, 0.20). • The current spot price is 95 cents. • The discount rate for this kind of project (from the CAPM) is 10% and the riskless rate is 5%.

  37. Conclusions Decision Tree Analysis modifies the simple NPV-rule: • The simple NPV rule gives generally not the correct conclusion if uncertainty can be “managed”. • The value of flexibility must be taken into account explicitly (cost of “killing an option”). • Properly calculated NPV remains the correct tool for decisions and evaluation of alternative strategies.
