This is simply the company's most recent quarter net worth divided by the latest shares outstanding. Often of interest to value investors, the book value per share ratio is an expression of how much in actual value would be left for each share if the company went out of business. This figure can be especially noteworthy when considering a turnaround situation. Sometimes a firm's stock is so beaten down that shares are trading at or below book value, implying a real bargain (or that its balance sheet overstates its assets). In such circumstances, a look at cash and marketable securities per share can help. Book value per share is not to be confused with "break-up value," which attempts to determine what the parts of a company might be worth if sold off. This figure is much harder to pinpoint but is considered by many analysts more realistic. It is also usually higher than book value.
