Dreman, Frank, Dorfman, and an army of other value investors and researchers have done study after study on this subject. Here are two internet related sites:tweedybrowne.com books.global-investor.com I use stated book value/sh. It is generally the stockholder equity part in the eqation divided by outstanding shares. I generally do not use tangible book value. Tangible book value is often (depending on one's definitions of tangible) a more conservative number because it does not include goodwill. Many people believe tangible book value is a better number and a more realistic or solid number to use when looking at what should comprise book value. I use stated book value/sh. because it's an easy number to screen for. Also, I'm interested in comparatives, for example, year over year changes. So as long as book value definition is consistent, I find for my purposes, stated book value is okay. I don't ignore tangible book value if I come across it - it can provide additional information about margin of safety. Similarly, if I become aware of off-sheet liabilities (some types of leases, special purpose entities, etc.), I'll qualitatively consider such in my overal evaluation of the company. I usually don't search through 10K's though for such items. And as you imply, bruwin, we'd be talking industrial companies and the like. For service companies, tech companies, etc., book values and p/bk numbers may not be significant as value determinants.
