What is Book Value?
Definition
Book value is the net asset value of a company, calculated as total assets minus total liabilities from the balance sheet. It represents the theoretical amount shareholders would receive if the company liquidated all assets and paid off all debts.
Detailed Explanation
Book value is an accounting concept that reflects the historical cost of a company's net assets. Book value per share is calculated by dividing shareholders' equity by the number of shares outstanding. It serves as a floor valuation and is the basis for the P/B ratio.
Tangible book value excludes intangible assets like goodwill and patents, providing a more conservative measure.
Book value reflects historical cost rather than current market value, so assets may be worth more or less than stated. Real estate purchased decades ago may be carried at a fraction of its market value.
For banks and financial institutions, book value is particularly important because their assets are closer to market value. Warren Buffett's Berkshire Hathaway historically used book value growth as its primary performance metric.
Formula
Book Value = Total Assets - Total Liabilities
Book Value Per Share = Shareholders' Equity / Shares OutstandingExample
If a company has total assets of $200 billion and total liabilities of $130 billion, its book value is $70 billion. With 5 billion shares outstanding, book value per share is $14.
