Managing Strategic Investment in an Uncertain World:A Real Options Approach Roger A. Morin, PhD Georgia State University FI 8360 January 2003
3 Valuation Frameworks Discounted Cash Flow (DCF) • Comparables Option Value
Agenda • The value of flexibility • Real options as a way to capture flexibility • Real options and financial options • So what? The importance of real options • Implementing real option valuation • Next steps
Capital Investments as Options All kinds of business decisions are options!
Virtually every corporate finance decision involving the issuance of securities or the commitment of capital to a project involves options in one way or another.
Nobel Prize-winning work of Black-Merton-Scholes Applications for real (nonfinancial) assets Extensions for how real assets are managed What is the value of a contract that gives you the right, but not the obligation to purchase a share of IBM at $100 six months from now? What is the value of starting a project that gives you the right, but not the obligation, to launch a sales program at a cost of $7M six months from now? We operate in a fast changing and uncertain market. How can we better make strategic decisions, manage our investments, and communicate our strategy to Wall St? Real Options Defined
Why An Options Perspective? • Some shortcomings in the use of ordinary NPV analysis can be overcome • Common ground for uniting capital budgeting and strategic planning can be established • Risk-adjusted discounted rates problem
Investment Decisions 1. Irreversibility 2. Uncertainty 3. Flexibility • Timing • Scale • Operations
Investment Decisions 1 & 2 3 is valuable 1 & 2 & 3 Option (flexibility) valuation
Option Value (a.k.a. flexibility) • Can be large • Sensitive to uncertainty • Explains why firms appear to underinvest
Flexibility: Investments have uncertainty and decision-points Fund First Develop Test Product Sales Brand Retire Research Results More Market Launch Extension Product New Information Your decision
What types of investments does this describe? • R&D related businesses - biotech, pharmaceuticals, entertainment. • Natural resource businesses - extractive industries. • Consumer product companies • High-tech companies
Real Option Type Real Option Category Scale Up Invest/ Grow Switch Up Scope Up Defer/ Learn Study/Start Scale Down Disinvest/ Shrink Switch Down Scope Down
Current Applications:Some Frequently Encountered Real Options • Timing -- now or later • Exit -- limiting possible future losses by exiting now • Flexibility -- today’s value of the future opportunity to switch • Operating -- the value of temporary shutdown • Learning -- value of reducing uncertainty to make better decision • Growth -- today’s value of possible future payoffs
Future Growth Options • Valuable new investment opportunities (“follow-on projects”) can be viewed as call options on assets • Examples: • Exploration • Capacity expansion projects • New product introductions • Acquisitions • Advertising outlays • R&D outlays • Commercial development
Investment Project Options: Examples • Growth Option (“Follow-On Projects”) • Nortel commits to production of digital switching equipment specially designed for the European market. The project has a negative NPV, but is justified by the need for a strong market position in this rapidly growing, and potentially very profitable, market. • Switching Option • Atlanta Airways buys a jumbo jet with special equipment that allows the plane to be switched quickly from freight to passenger use or vice versa.
Investment Project Options: Examples • Timing Option • Dow Chemical postpones a major plant expansion. The expansion has positive NPV, but top management wants to get a better fix on product demand before proceeding. • Flexible Production Facilities • Lucent Technologies vetoes a fully-integrated, automated production line for the new digital switches. It relies on standard, less-expensive equipment. The automated production line is more efficient overall, according to a NPV calculation.
Investment Project Options: Examples • Fuel Switching • A power plant has the capacity of burning oil or gas. Mgrs can decide which fuel to burn in light of fuel prices prevailing in the future • Shut-Down Option • A power plant can be shut down temporarily. Mgt. can decide whether or not to operate the plant in light of the avoided cost of power prevailing in the future • Investment Timing • Mgt. can invest in new capacity now or defer when more information on demand growth and fuel prices is available
Which is a closer analogy to these types of projects? Bond Option
Standard NPV analysis treats projects like bonds Average promised cash flow up-front investment
NPV ignores valuable flexibility Invest Learn Do not invest Decide
Shortcomings of NPV Analysis • Passive, assumes business as usual with no management intervention • Strategic factors ignored • NPV understates value • Operating flexibility ignored • Valuable follow-on investment projects ignored • Many investments have uncertain payoffs that are best valued with an Options approach • Risk-adjusted discounted rates problem
NPV ROV Certainty is a narrow path!

Financial Options A Brief Review
What is an option? • An option provides the holder with the right to buy or sell a specified quantity of an underlying asset at a fixed price (exercise price) at or before the expiration date of the option. • Since it is a right and not an obligation, the holder can choose not to exercise the right and allow the option to expire. • Two types – call options (right to buy) and put options (right to sell).
Call Options • A call option gives the buyer of the option the right to buy the underlying asset at a fixed price (E) at any time prior to the expiration date. The buyer pays a price for this right (premium) • At expiration, • If the value of the underlying asset S > E • Buyer makes the difference: S – E • If the value of the underlying asset S < E • Buyer does not exercise • More generally, • Value of a call increases as the value of the underlying asset increases • Value of a call decreases as the value of the underlying asset decreases
Payoff on Call Option Net payoff on call option Exercise price Price of underlying asset If asset value < exercise price, you lose what you paid for call
Payoff on IBM Call Option Net payoff E = $100 IBM Stock price Breakeven = $105 Maximum loss = $5
Put Options • A put option gives the buyer of the option the right to sell the underlying asset at a fixed price (E) at any time prior to the expiration date. The buyer pays a price for this right (premium) • At expiration, • If the value of the underlying asset S < E • Buyer makes the difference: E – S • If the value of the underlying asset S > E • Buyer does not exercise • More generally, • Value of a put decreases as the value of the underlying asset increases • Value of a put increases as the value of the underlying asset decreases
Payoff on Put Option Net payoff on put Exercise price Price of underlying asset If asset value > exercise price, you lose what you paid for put
Determinants of Call Option Value • Stock Price - the higher the price of the underlying stock, the greater the option’s intrinsic value • Exercise Price - the higher the exercise price, the lower the intrinsic value • Interest Rates - the higher interest rates, the more valuable the call option • Volatility of the Stock Price - the more volatile the stock price, the more valuable the option • Time to Maturity - call options increase in value the more time there is remaining to maturity
Effect of Volatility on Option Values Call Option Payoff Probability 10% Volatility 30% Volatility Asset Price Time to expiration is one year.
Effect of Maturity on Option Value Probability 1 Yr Expiration Call Option Payoff 5 Yrs Expiration Asset Price Volatility is 20%.
Option Premium vs Intrinsic Value C Call option price Time value Intrinsic value C 0 X Stock Price X = Exercise Price CC = Call option premium as function of stock price
Determinants of option value • Variables Relating to Underlying Asset • Value of Underlying Asset • Variance in that value • Expected dividends on the asset • Variables Relating to Option • Exercise Price • Life of the Option • Level of Interest Rates
American vs European Options • American: exercise at any time • European: exercise at maturity • American options more valuable • Time premium makes early exercise sub-optimal • Exception: • Asset pays large dividends
Option Valuation • Binomial Option Pricing Model • Portfolio Replication Method • Risk Neutral Method • Black-Scholes Model • Dividend adjustment • Diffusion vs Jump process
Binomial Option Pricing Model • The Binomial Option Pricing Model assumes that there are two possible outcomes for the price of the underlying asset in each period. • Although this assumption is artificial, realism can be achieved by partitioning the time horizon into many short time intervals, so the number of possible outcomes is large • Useful first approximation
Binomial Price Path Su2 Su Sud S Sd Sd2
Binomial Price Path $120 $110 $100 $100 $90 $80 t = 0 t = 1 t = 2
Creating a replicating portfolio • Objective: use a combination of risk-free borrowing-lending and the underlying asset to create the same cash flows as the option being valued • Call = Borrowing + Buying Δ of Underlying Stock • Put = Selling short Δ on Underlying Asset + Lending • The number of shares bought or sold is called the option delta • The principles of arbitrage then apply, and the value of the option has to be equal to the value of the replicating portfolio
Replicating Portfolio Δ Su - $B (1 + r) = Cu Δ Sd - $B (1 + r) = Cd Δ = No. of units of underlying asset bought Cu - Cd Δ = Su - Sd
Replicating Portfolio: Example 1 $55 Stock: $50 $45 1-yr Call, E = $50 Rf = 5% C = $3.57 all investors agree!
Replicating Portfolio: Example 1 Call - Stock Payoffs: (55, 5) (50, ?) (45, 0) We can duplicate the above payoffs with a position in common stock and borrowing, that is, by “portfolio replication”.
Replicating Portfolio Δ Su - $B (1 + r) = Cu Δ Sd - $B (1 + r) = Cd Cu - Cd $5 - $0 Δ = = = 0.50 Su - Sd $55 - $45 Δ = 50 shares ! B = $2,142 !
50 shares of stock + 1-year loan of $2,142.86 Portfolio is now worth: 50 x $50 - $2,142.86 = $357.14 Portfolio payoffs: 50 x $55 - 2,250 = 500 (50, ?) 50 x $45 - 2,250 = 0 SAME AS CALL OPTION PAYOFFS! FAIR VALUE OF 100 CALLS = $357.14
