  1. From financial options to real options4. Financing real options Prof. André Farber Solvay Business School ESCP March 10,2000 Financing real options

  2. Financing new ventures: • For new ventures, financing needs are greater than initial capital available. • Outside financing required? How? • Debt ? principal source of outside financing for companies. • Equity ? • Convertible bonds (or bonds with warrants)? • An example: • Current value of company : 80, no debt, 100 shares • Financing needed: 70 Financing real options

  3. Debt • Suppose it borrows by issuing a 2-year zero-coupon with a face value of 80. • If, at maturity, V*< 80: financial trouble…. • Ultimate solution: bankruptcy, stockholders loose everything • Now, let’s look at the value of equity in 2 years: V*<80 V*>80 Value of equity 0 V* - 80 • This is like a call option: stocks of a levered company are similar to a call option on the company with a striking price equal to the face value of the debt. Financing real options

  4. Pricing the equity and the debt • Let’s use Black Schole to value the equity and the debt • In our example: Maturity = 2, K = 100 • Here: V = 150, r = 5%, Volatility = 40% • Using BS: C = 80 this is the market value of equity today • So : Equity = 80 • Debt = 150 - 80 = 70 (thanks to Modigliani Miller) • Borrowing rate = 7.13% Financing real options

  5. More on debt value • Value of company = Value of equity + Value of debt • Now, remember put-call parity : S = C + PV(K) - P • Let’s map market value debt and equity onto option values Value of company S Stock price Value of equity C Call option Value of debt PV(K) - P PV(Strike) - Put option • Why this put option? • Limited liability acts as an insurance for the stockholders • The amount that they borrow is the difference between • the value of a risk-free bond (72.4 in our example) • the value of a put option (2.4) Financing real options

  6. Agency problems related to debt • We are now in a position to better understand conflicts of interests between stockholders and bonds holders: • incentive to take large risks • incentive toward underinvestment • milking the property • increasing debt Financing real options

  7. Taking risk • By increasing the risk of the company, stockholders could fool bondholders by increasing the value of their stocks at the expense of the bonds • Remember, stocks similar to call option : value increasing function of volatility • Example:  = 40%  = 50%  Market value of equity 80.3 83.2 + 2.9 Market value of debt 69.7 66.8 -2.9 Financing real options

  8. Underinvesting • Stockholders might decide not to invest in a project with positive NPV. • Example: • Following project has been identified: Cost = 49, NPV = 1 • Going ahead with the project will increase the value to 200. • Should they go ahead if the project is equity-financed? V = 150 V = 200  Market value of equity 80.3 128.6 + 48.3 Market value of debt 69.7 71.4 +1.7 • Stockholders loose: they invested 49 but the value of their equity increases only by 48.3 • Bondholders gain : the risk on their debt has decreased Financing real options

  9. Milking the property • Stockholders might be tempted to pay themselves a dividend at the expense of the bondholders • Example: • Stockholders sell assets worth 50 and use the proceed to pay a dividend. The value of the company drops to 100. V = 150 V = 100  Market value of equity 80.3 35.9 - 44.4 Market value of debt 69.7 64.1 -5.6 • Stockholders gain: Dividend + Change in market value = + 5.6 • Bondholders are  Financing real options

  10. Borrowing • Another temptation in to increase debt. • Example: • Stockholders borrow an additional 50 (2-year zero-coupon with face value 60) and invest it in a project with NPV=0. V = 150 V = 200  Market value of equity 80.3 83.8 + 3.5 Market value of old debt 69.7 66.2 - 3.5 Market value of new debt - 50.0 Financing real options

  11. Controling conflicts of interests • Bondholders should keep a close eye on the company • They will impose bond covenants • dividends • sales of assets • issuing new debt • minimum working capital • providing information to lender. Financing real options

  12. How to value the company ? How to share the pie? Issuing equity New equity Debt Value of company Financing real options

  13. Bonds with Warrants • Give the right to its owner to buy a number of shares issued by a firm at a price set in advance. • Issued most frequently with bonds: • Price set for the "package" : Bond + Warrants • Traded separately after issue • Similar to call option but two main differences: • 1. Warrants are issued by the company: • If exercised, new stocks.are issued • 2.Proceeds of the sale of warrant goes to company Financing real options

  14. Back to our example • V = 80 Equity = 80 (100 shares, price = 0.80/share) • Issue 50 bonds with 1 warrant, maturity 2 years. • Face value of bonds = 1.60/bond • Striking price of warrant = 1.60 • Issue price = 1.40/ bond with warrant attached • Proceed of the issued: • If warrant exercised, the company • issues 50 new shares • collects the proceed of the issue 50 x 1.60 = 80 Financing real options

  15. To exercise or not to exercise.. • Suppose V* = 300 at maturity • Value of company = VT - D + m * K = 300 - 80 + 80 = 300 • Repartition of shares: • Number Fraction Value • Old 100 2/3 200 • New 50 1/3 100 • Total 150 300 • Gain for warrant holders: • m * PT - m * K = 50 * 2.00 - 50 * 1.60 • = 20 (0.40 / warrant) Financing real options

  16. When to exercise the warrants? • If they exercise their warrants, warrantholders will own a fraction q of the shares : • They will exercise if the value of their shares is greater than the amount to pay : Exercise if : q (VT -D + m * K) > m * K • Warrant exercised if :q VT > (1 - q) m K + qD <=> VT > n * K-D • In our example : 1/3 (VT - 80 + 80) > 80 => VT > 240 Financing real options

  17. Warrants vs calls • Value of warrants at maturity V 180 210 240 270 300 330 50 Warrants 0 0 0 10 20 30 • Now consider 100 call options on the shares of the company K = 2.4 V 180 210 240 270 300 330 100 Calls 0 0 0 30 60 90 • At maturity, the 50 warrants are worth 1/3 of the value of the 100 calls 50 WT = (1/3)  Max(0, VT - 240) • More generally : m * WT = q * MAX ( 0, VT -D - n * K) • with q = m/(n+m) Financing real options

  18. Valuing a warrant • Step 1: Value n calls on the company using BS • (in our example: S=150, K=240, Maturity = 2, r = 5%,  = 40%) • Value of 100 calls = 15.41 • Step 2: Calculate value of 1 warrant by dividing by m • Value of 50 warrant = 1/3 x 15.41 = 5.13 • Value of 1 warrant = 5.13/50 = 0.10 Financing real options

  20. Convertible bond less sensitive to volatility Financing real options
