*“Many shall be restored that are now fallen and many shall fall that are now in honor.”Horace, the Latin lyric poet and satirist, Ars Poetica*

The discipline of value investing is a powerful and time-tested approach which has rewarded its disciples through bear markets, bull markets and recessions. Bruce Greenwald’s Value Investing – From Graham to Buffett and Beyond does a superb job laying out the fundamentals as they have evolved since Graham pioneered this school of thought. The book uses case studies to reinforce the concepts including a detailed look at Intel in the late ‘80s and early ‘90s. The second half of the book consists of 8 chapters devoted to the investment approach of some of the most celebrated value investors of all time including Buffett, Greenberg, Klarman and the Schlosses.

This book will become an invaluable investment resource and you will end up referring back to it over and over again. Here is a quick primer on how you estimate the intrinsic value of a security:

- Calculate the Net Asset Value of the company. You do this by calculating the Reproduction Cost of the assets. In other words, if a competitor were to enter the market, how much would it need to spend to get in the game. The NAV is calculated by making adjustments to the Book Value which include R&D and Marketing and Advertising expenditures a competitor would need to spend in order to become a genuine challenger. You can use the adjusted book value to calculate a Market Value to NAV ratio as an initial gauge of how expensive a stock may be.

- Calculate the Earnings Power Value of the company. To calculate EPV, you start with operating income (EBIT) and make adjustments which include adding back depreciation and amortization and subtracting capital expenditures. This is the same as the distributable cash flow to shareholders assuming no growth. A hard core value investor never assumes any growth when calculating the intrinsic value of a company. We will get to this later. This number is then divided by the cost of capital to calculate EPV. Note that a value investor does not have to contend with the practically impossible task of estimating what a company’s growth prospects may be five or ten years down the road. This eliminates a lot of uncertainly. Incidentally, the difference between the EPV and the NAV, when positive, is called the franchise value. In other words, the company’s moat. The EPV must then be adjusted so you can compare it with the current market cap of the company. To do this, you subtract interest bearing debt and add back all cash in excess of 1% of sales (1% of sales in cash is about how much is needed to operate a company). For a value investor, this is the intrinsic value of the company. Ideally you want to buy the stock when it is trading below the EPV to provide yourself with a Margin of Safety.

- So what about growth? What value can we ascribe to growth when we are calculating the intrinsic value of a company such as Intel? The answer is simple. You have to assess whether the company can grow without destroying shareholder value. I won’t get into the details, but basically if the company is going to reinvest excess cash into its operations, it must earn in excess of the cost of capital to create value for existing shareholders. Greenwald calls this growth within the franchise. To calculate what I will call the Growth Factor which is the ratio of the Present Value of Future Cash Flows (PV) to EPV, you need to estimate a growth rate and calculate two ratios: Return on Equity/Cost of Capital and Growth Rate/Cost of Capital. Don’t worry about the math, but with those two ratios in hand you can calculate a Growth Factor. This is how it works. A ratio of 2.0 means the company’s intrinsic value could be twice the calculated EPV. Conversely, if you decide to buy the stock at EPV, the company’s growth should provide you with a 50% Margin of Safety.

A lot has changed since Greenberg wrote the 2001 edition of his book. But keeping his assumptions constant for a quick back of the envelope calculation justifies a $27 intrinsic value for Intel (Nasdaq: INTC). At today’s price this provides only a 25% Margin of Safety. Not enough for a value investor.
