VALUING EQUITY AS AN OPTION
This program calculates the value of equity as a call option
on the value of the underlying firm.
	Assumptions
	1. All the assumptions underlying the Black-Scholes model apply
	2. The value of the firm is known.
	The user has to input the following variables
	1. Current value of the underlying firm (or its assets).
	2. Variance in the ln(value) of the underlying firm.
	3. Face Value of the outstanding debt.
	4. Riskless interest rate that corresponds to average duration of debt.
	5. Face-value weighted duration of the debt outstanding of the firm.
	6. Expected dividend yield on the stock of the firm.
	Inputs relating the underlying asset
	Enter the value of the firm =				$1,200.00	(in currency)
	There are two ways of estimating standard deviation. One is to use the firm's own stock and bond prices to estimate it. The other is to use the variance of the industry to which your firm belongs.
	Which approach would you like to use to estimate variance?				F
	Stock & Bond Price Variance
	Are the stocks and bonds of this firm traded?				Yes
	Enter the standard deviation in the firm's stock price (ln) =				25%
	Enter the standard deviation in the firm's bond price (ln) =				10%
	Enter the correlation between the stock and bond prices =				0.3
	Enter the average D/(D+E) ratio during the variance estimation period =				90%
	Based upon these inputs, the standard deviation is=			10.04%
	Industry average variance in firm value
	If yes, enter the annualized standard deviation in ln(value) of asset				15.00%
	Enter the current annualized dividends on the stock (total)				$0.00	(in currency)
	This will result in a dividend yield of			0.00%
	Do you want to change this dividend yield for the life of the option?				No	(Yes or No)
	If yes, enter the new dividend yield for the life of the option =					(in %)
	Inputs relating to the option
	Enter the cumulated face value of outstanding debt =			$1,844.50	(in currency)	[Add coupons to the face value of debt]
	Enter the average duration of outstanding debt =			3.94	(in years)
	(Weighted by the face value of the debt)
	General Inputs
	Enter the riskless rate that corresponds to the option lifetime =				8.00%	(in %)
Output
Stock Price=		$1,200.00		T.Bond rate=		8.00%
Strike Price=		$1,844.50		Variance=		0.010075
Expiration (in years) =		3.94		Annualized dividend yield=		0.00%
	d1 =	-0.48
	N(d1) =	#NAME?
	d2 =	-0.67
	N(d2) =	#NAME?
Value of equity as a call =			#NAME?
Value of outstanding debt =			#NAME?
Appropriate interest rate for debt =			#NAME?
