Key Concepts and Skills • Understand the options terminology • Be able to determine option payoffs and pricing bounds • Understand the five major determinants of option value • Understand employee stock options • Understand the various managerial options • Understand the differences between warrants and traditional call options • Understand convertible securities and how to determine their value

3. Chapter Outline • Options: The Basics • Fundamentals of Option Valuation • Valuing a Call Option • Employee Stock Options • Equity as a Call Option on the Firm’s Assets • Options and Capital Budgeting • Options and Corporate Securities

4. Option Terminology • Call • Put • Strike or Exercise price • Expiration date • Option premium • Option writer • American Option • European Option

5. Stock Option Quotations • Look at Table 14.1 in the book • Price and volume information for calls and puts with the same strike and expiration is provided on the same line • Things to notice • Prices are higher for options with the same strike price but longer expirations • Call options with strikes less than the current price are worth more than the corresponding puts • Call options with strikes greater than the current price are worth less than the corresponding puts

6. Option Payoffs – Calls • The value of the call at expiration is the intrinsic value • Max(0, S-E) • If S<E, then the payoff is 0 • If S>E, then the payoff is S – E • Assume that the exercise price is \$35

7. Option Payoffs - Puts • The value of a put at expiration is the intrinsic value • Max(0, E-S) • If S<E, then the payoff is E-S • If S>E, then the payoff is 0 • Assume that the exercise price is \$35

8. Work the Web Example • Where can we find option prices? • On the Internet, of course. One site that provides option prices is Yahoo Finance • Click on the web surfer to go to Yahoo Finance • Enter a ticker symbol to get a basic quote • Follow the options link • Check out “symbology” to see how the ticker symbols are formed

9. Call Option Bounds • Upper bound • Call price must be less than or equal to the stock price • Lower bound • Call price must be greater than or equal to the stock price minus the exercise price or zero, whichever is greater • If either of these bounds are violated, there is an arbitrage opportunity

10. Figure 14.2

11. A Simple Model • An option is “in-the-money” if the payoff is greater than zero • If a call option is sure to finish in-the-money, the option value would be • C0 = S0 – PV(E) • If the call is worth something other than this, then there is an arbitrage opportunity

12. What Determines Option Values? • Stock price • As the stock price increases, the call price increases and the put price decreases • Exercise price • As the exercise price increases, the call price decreases and the put price increases • Time to expiration • Generally, as the time to expiration increases both the call and the put prices increase • Risk-free rate • As the risk-free rate increases, the call price increases and the put price decreases

13. What about Variance? • When an option may finish out-of-the-money (expire without being exercised), there is another factor that helps determine price • The variance in underlying asset returns is a less obvious, but important, determinant of option values • The greater the variance, the more the call and the put are worth • If an option finishes out-of-the-money, the most you can lose is your premium, no matter how far out it is • The more an option is in-the-money, the greater the gain • You gain from volatility on the upside, but don’t lose anymore from volatility on the downside

14. Table 14.2

15. Employee Stock Options • Options that are given to employees as part of their benefits package • Often used as a bonus or incentive • Designed to align employee interests with stockholder interests and reduce agency problems • Empirical evidence suggests that they do not work as well as anticipated due to the lack of diversification introduced into the employees’ portfolios • The stock just is not worth as much to the employee as it is to an outside investor

16. Equity: A Call Option • Equity can be viewed as a call option on the company’s assets when the firm is leveraged • The exercise price is the value of the debt • If the assets are worth more than the debt when it comes due, the option will be exercised and the stockholders retain ownership • If the assets are worth less than the debt, the stockholders will let the option expire and the assets will belong to the bondholders

17. Capital Budgeting Options • Almost all capital budgeting scenarios contain implicit options • Because options are valuable, they make the capital budgeting project worth more than it may appear • Failure to account for these options can cause firms to reject good projects

18. Timing Options • We normally assume that a project must be taken today or foregone completely • Almost all projects have the embedded option to wait • A good project may be worth more if we wait • A seemly bad project may actually have a positive NPV if we wait due to changing economic conditions • We should examine the NPV of taking an investment now, or in future years, and plan to invest at the time that produces the highest NPV

19. Example: Timing Options • Consider a project that costs \$5000 and has an expected future cash flow of \$700 per year forever. If we wait one year, the cost will increase to \$5500 and the expected future cash flow increase to \$750. If the required return is 13%, should we accept the project? If so, when should we begin? • NPV starting today = -5000 + 700/.13 = 384.16 • NPV waiting one year = (-5500 + 800/.13)/(1.13) = 578.62 • It is a good project either way, but we should wait until next year

20. Managerial Options • Managers often have options after a project has been implemented that can add value • It is important to do some contingency planning ahead of time to determine what will cause the options to be exercised • Some examples include • The option to expand a project if it goes well • The option to abandon a project if it goes poorly • The option to suspend or contract operations particularly in the manufacturing industries • Strategic options – look at how taking this project opens up other opportunities that would be otherwise unavailable

21. Warrants • A call option issued by corporations in conjunction with other securities to reduce the yield • Differences between warrants and traditional call options • Warrants are generally very long term • They are written by the company and exercise results in additional shares outstanding • The exercise price is paid to the company and generates cash for the firm • Warrants can be detached from the original securities and sold separately

22. Convertibles • Convertible bonds (or preferred stock) may be converted into a specified number of common shares at the option of the bondholder • The conversion price is the effective price paid for the stock • The conversion ratio is the number of shares received when the bond is converted • Convertible bonds will be worth at least as much as the straight bond value or the conversion value, whichever is greater

23. Valuing Convertibles • Suppose you have a 10% bond that pays semiannual coupons and will mature in 15 years. The face value is \$1000 and the yield to maturity on similar bonds is 9%. The bond is also convertible with a conversion price of \$100. The stock is currently selling for \$110. What is the minimum price of the bond? • Straight bond value = 1081.44 • Conversion ratio = 1000/100 = 10 • Conversion value = 10*110 = 1100 • Minimum price = \$1100

24. Other Options • Call provision on a bond • Allows the company to repurchase the bond prior to maturity at a specified price that is generally higher than the face value • Increases the required yield on the bond – this is effectively how the company pays for the option • Put bond • Allows the bondholder to require the company to repurchase the bond prior to maturity at a fixed price • Insurance and Loan Guarantees • These are essentially put options

25. Quick Quiz • What is the difference between a call option and a put option? • What is the intrinsic value of call and put options and what do the payoff diagrams look like? • What are the five major determinants of option prices and their relationships to option prices? • What are some of the major capital budgeting options? • How would you value a convertible bond?

26. . INTRODUCTION TO OPTIONS

27. Options - Outline • Derivative Security • Definitions • Examples • Buy a Call • Buy a Put • Write a Covered Call • Pricing • factors on which price depends • Short-cut to approximate price • Additional topics • Using Options as Hedge • 12 ways to buy S& P 500

28. Derivative Instruments • Some contracts give the contract holder either the obligation or choice to buy or sell a financial asset. • the price of those contracts derive its value from the price of the underlying financial asset • so, these contracts are called derivative instruments • options • futures, forwards • swaps, caps, floors, collars

29. Derivatives • Reasons to use • reduce risk • change nature of one’s financial exposure • reduce transaction costs • classified on basis of underlying asset, index or currency to which linked • some standardized contracts are traded on exchanges while others are customized, OTC • history - 1670 in Amsterdam; 1848 CBT, 1865 futures, 1972 currency futures; 1975 financial futures • 1900s Put & Call Dealers Association, 1973 CBOE, 1975 AMEX & PHLX

30. Definitions - Options • buy = own • write = sell • option price = option premium • exercise price = strike price • expiration date = maturity • call • put • American • European • covered vs. naked • Exchange-traded vs. OTC (dealer)

31. Options • Buy an option- own an option • have Right (but NOT obligation) to buy or sell an item at a predetermined price (strike price) until some future date • write or sell an option - then if the owner (holder) of option wants to exercise it, you are obligated to sell or buy the item • if have a mortgage on your home, you own an option - the right to prepay your mortgage. • When signed contract to take mortgage - bought option -right to borrow at that interest rate, but if rates fell, could walk away & only lose commitment fee; nonrefundable deposit to lock in price & deal on home sale - buyer can walk away & lose only deposit.

32. Options vs. Futures Contracts • The option at the strike price exists over the period of time (if American) , at a given date (if European). • The buyer of an option pays the seller (writer) a premium which the writer keeps - whether or not the option is ever exercised.- in futures no party compensates the other • The option does not have to be exercised by buyer; it can be sold, if it has a market value, before expiration date.- in futures both are obligated to perform. • Option buyer sets price at which can acquire underlying but can take advantage of more favorable price; in futures - price is locked in • Gains and losses are unlimited with futures contracts; with options the buyer can lose only the premium and the commission paid. • With futures both put up margin, with options- only writer posts margin; writer position is marked to market; both in futures

33. Calls and Puts • Call option -- buyer has the option to buy an item at the strike price. • Put option -- buyer has the option to sell an item at the strike price. It is vital to know who has the Right to transact vs. who may be Obliged to transact in order to determine the direction of currency flows at expiry 16 -33

34. Covered and Naked Options • Covered option -- writer either owns the security involved in the contract or has limited his or her risk with other contracts. • Naked option -- writer does not have or has not made provision to limit the extent of risk. American vs European Options American - the option can be exercised at any time before expiration or maturity The option may be exercised at any time up to and including the expiry date and the funds will be transferred with spot value from exercise European - the option can only be exercised on the expiration or maturity date The option may only be exercised on the expiry date and the funds will be transferred on the value date

35. Option Terminology • Buy - Long • Sell - Short • Call • Put • Key Elements • Exercise or Strike Price • Premium or Price • Maturity or Expiration Market and Exercise Price Relationships In the Money - exercise of the option would be profitable Call: market price>exercise price Put: exercise price>market price Out of the Money- exercise of the option would not be profitable Call: market price<exercise price Put: exercise price<market price At the Money - exercise price and asset price are equal

36. Call Option Example (pretend it is Nov 2002) • Suppose you pay \$3 for an Dec 50 call on XYZ stock. • Since each option is to buy 100 shares of stock, you would pay \$300. • XYZ Dec 50 \$3 • 100 x \$3 = \$300 • Stock Expiration Strike Premium • Month Price • By paying \$300, the premium, you have the right to purchase 100 shares of XYZ at any time (American) before the option expires on the third Friday in December (12/20/02) at \$50 per share. (Can buy an option up to 3 years but most are for 3 months or less.) • Like the buyer concluding he/she wants to purchase the house, the option buyer can exercise the option and purchase the stock at \$50 per share if the stock trades above \$50 per share (e.g., \$60).

37. illustration • Stock price • 60 - --- • 50- ___________________ strike price • 40 - expiration date • If the stock falls below \$50, call option buyer has no obligation to purchase the stock; he can let the option expire worthless and the only loss is the \$300 option premium (analogous to the deposit on the home).

38. Summary, so far • Discussed premium, strike price, expiration month • what are reasons to buy a call • Leverage • Limitation of risk to premium paid • Buying call options gives you the ability to participate in stock movement by paying only option premium • Leverage - suppose buy 100 shares at \$50 per share; pay \$5000. If XYZ stock rises to \$60 per share, may be able to sell stock for \$6000 (excluding commissions & taxes) - profit = \$1000 or 20%

39. Leverage • Suppose instead of buying stock, you purchase an XYZ call for \$300. • Then if the stock rises to \$60 per share, pay \$5000 and immediately sell for \$6000. • Make \$1000 Profit • less 300 Option Premium • \$ 700 Profit on \$300 investment • or 233 percent - that’s leverage • By buying the stock option can participate in the price movement for three months. • Of courseleverage works both ways. If the stock price falls, can have a loss on the options. • But the most you can lose is the premium you paid of \$300.

40. How is option profitable? • Suppose the stock rises to \$52. • Then you can buy for \$50 and sell for \$52, making \$200 on the stock transaction. • However, since you paid \$300 premium for the option, your net position is a \$100 loss. • If you had bought the stock (without buying the option), then you would have made \$200. Buying the option was like buying an insurance policy. • For the call option purchase to be profitable, the stock price must rise enough in value to cover the cost of the option premium plus any transaction costs. • What if the stock price instead of rising a small amount, actually fell (as the stock market did through much of 2002) to e.g., \$43 per share. • Then have a loss of \$7 per share, or \$700 on 100 shares.

41. Risk • If XYZ is trading below \$50, you will not exercise the option, but will let it expire worthless and forfeit the premium of \$300. Hence there is some risk with options. • With stock ownership get full upside and downside potential. With option ownership, you can participate in the potential profit, but the loss is limited to the option premium paid. • Stock price Stock profit Option profit • 80 + 30 + 27 • 70 + 20 + 17 • 60 + 10 + 7 • 50 0 - 3 • 40 - 10 - 3 • 30 - 20 - 3 • 20 - 30 - 3 • 10 - 40 - 3 • Do you have to exercise the call? No. Can sell the call because options are traded on an exchange. Can sell for < or > price paid, depending on where the stock is trading & how long until expiration.

42. Put Options • If the market is falling, there are options to provide protection. The put option is similar to the call option in that we have an exercise price, an expiration month and a premium. • If you buy a put, you have the right to sell a stock at a particular price before a particular date. • For example, you may buy an Dec 45 put on ZYX for \$1. • Stock Expiration month Strike price Premium • ZYX June 45 \$1 • 100 x \$1 = \$100 • If ZYX falls, say to \$40, prior to the third Friday in Dec., then the option has a value of approximately \$5, representing the difference between the strike price and the current market price. In this example, owning the put gives the holder the right to sell the stock at \$5 above the market price. If the market is above \$45, allow the option to expire and lose only the premium that you paid.

43. Using puts as protection • Suppose you bought the stock at \$50 and the price has risen to \$65. You could sell it and take a profit, or if you are worried about the next market “correction” but would like to hold the stock if the market does not drop, you could buy a put at \$60 or \$65 and then exercise that put if the market falls. If the market continues to rise, you can hold onto the stock. The gains on the stock will be reduced by the premium paid for the put. But the most money that you can lose is the premium that you paid. You can think of the purchase of the option as analogous to the purchase of term insurance. • If you want to sell the option before it expires, you can because it is traded on an exchange during trading hours. But if you sell it, you no longer have the protection.
