From Net Income to Operating Income and Equity to Value 
		
		The profits margins for firms can be stated in terms of net income
		(as they have in all the examples so far) or in terms of operating
		income (EBIT). If pre-tax operating margins are used, the appropriate
		value estimate is that of the firm. In particular, if one makes
		the assumption that
Free Cash Flow to the Firm = EBIT (1 - tax rate): Net Capital exp. and working capital needs are zero.
Then the Value of the Firm can be written as a function of the after-tax operating margin= (EBIT (1-t)/Sales

where, 
		
		g = Growth rate in after-tax operating income for the first n
		years 
		
		gn = Growth rate in after-tax operating income after n years forever
		(Stable growth rate) 
		
		WACC = Weighted average cost of capital 
		
The value of a brand name
In general, the value of a brand name can be written as:
Value of brand name ={(V/S)b-(V/S)g }* Sales 
		
		(V/S)b = Value of Firm/Sales ratio of the firm with the benefit
		of the brand name 
		
		(V/S)g = Value of Firm/Sales ratio of the firm with the generic
		product 
		
		Illustration : Valuing a brand name: Kelloggs 
		
		The following is an analysis of brand name value at Kellogg Corporation.
		The estimates for Kellogg were obtained from 1994 financial statements.
		The after-tax operating margin for the generic substitute was
		obtained by looking at a private-brand cereal manufacturer. The
		expected growth is assumed to be 
		
		Expected growth in after-tax operating income = Retention Ratio
		* Return on Assets

			Value of Kellogg Brand Name = ( 3.39 - 1.10) ($6562 million) =
			$15,026 million 
			
			Value of Kellogg as a company = 3.39 ($6562 million) = $22,271
			million 
			
Approximately 67.70% ($15026/$22271) of the value of the company can be traced to brand name value
		The danger of double-counting the value of a brand name
		The value of a brand name results in higher growth and higher
		value for the firm owning it. There are some analyses where the
		brand name value is double counted. To provide an illustration
		of how this could happen, assume that Coca Cola is valued using
		a discounted cashflow model and that the expected growth rate
		used in the valuation is 29.55%. This value already incorporates
		the value of the brand name through the use of the high growth
		rate. If an additional value is now assigned to the brand name,
		the brand name value is double counted.
