The reliability of the information and the strategic situation of both firms and industry usually influence the judgment when valuing an asset. Balance sheet is one example for illustrating the influence of the info reliability. Investors need to design how far down the balance sheet they need to go. Benjamin Graham considered only current assets in his valuation. Current assets valuation is accurate based on either liquidation or reproduction cost approach. For the strategic situation part, the investors need to think if the industry is viable. The asset value estimate is based on what they will bring in liquidation. But if they have no market, they can only be sold for scrap. So if the asset value is based on reproduction cost or liquidation approach, the investor need to look for an industry that is either stable or growing.
There are several things worth noting here.
The points to note I mentioned above are only some that I found very interesting. The book has also discussed other points such as the goodwill value and the method for assigning a value to the license or franchise. If readers are interested, please feel free to check them out.
