a. Using the Black-Scholes Option Pricing Model, how much is the equity worth?
Black-Scholes Option Pricing Model
Total Value of Firm 200.00 this is the current value of operations
b. How much is the debt worth today? What is its yield?
Debt value = Total Value – Equity Value = 79.15$ million
Debt yield = 8.107%
Equity value at 60% volatility 128.76748 million
Equity value at 45% volatility 120.85314 million
Percent change -6.1% million
d. Graph the cost of debt versus the face value of debt for values of the face value from $0.5 to $8 million.
