  1. Options and Corporate Finance

  2. 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 $30

  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 $30

  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 • The owner of the option gains 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 don’t work as well as anticipated due to the lack of diversification introduced into the employees’ portfolios • The stock isn’t worth as much to the employee as it is to an outside investor because of the lack of diversification – this suggests that options may work in limited amounts, but not as a large part of the compensation package

  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 face 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 forgone completely • Almost all projects have the embedded option to wait • A good project may be worth more if we wait • A seemingly 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 the project produces the highest NPV

  19. Example: Timing Options • Consider a project that costs $5,000 and has an expected future cash flow of $700 per year forever. If we wait one year, the cost will increase to $5,500 and the expected future cash flow will increase to $800. If the required return is 13%, should we accept the project? If so, when should we begin? • NPV starting today = -5,000 + 700/.13 = 384.62 • NPV waiting one year = (-5,500 + 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 required on the other securities • Differences between warrants and traditional call options • Warrants are generally very long term • They are written by the company and warrant exercise results in additional shares outstanding • The exercise price is paid to the company, generates cash for the firm, and alters the capital structure • Warrants can normally be detached from the original securities and sold separately • Exercise of warrants reduces EPS, so warrants are included when a firm reports “diluted EPS”

  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 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 $1,000 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 = 1,081.44 • Conversion ratio = 1,000/100 = 10 • Conversion value = 10*110 = 1,100 • Minimum price = $1,100

  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. End of Chapter

  27. Comprehensive Problem • A convertible bond has a straight bond value of $1,050. The conversion ratio is 24, and the stock price is $49 per share. What is the value of the option to convert? • What is the exercise value of a call and a put, each with an exercise price of $40, if the stock price is currently $50? • What if the stock price is $20?
