Book Value

Net asset value of a company on the balance sheet (assets minus liabilities).

Book value represents the net asset value of a company according to its balance sheet. It is calculated by taking the total value of a company's assets and subtracting its total liabilities. In essence, it is the theoretical amount that shareholders would receive if the company were to immediately liquidate all its assets and pay off all its debts at the values recorded on the books. Investors use book value to assess whether a stock is undervalued or overvalued relative to its actual balance sheet strength. It serves as the foundation for the price-to-book (P/B) ratio, a popular valuation metric. Historically, value investors sought out companies trading below their book value, viewing them as potential bargains with a margin of safety. However, book value has limitations. It is based on historical cost accounting, meaning the recorded value of assets like real estate or equipment may differ significantly from their current market value. Additionally, book value does not capture intangible assets well, such as brand reputation, intellectual property, or proprietary technology, which are often the primary drivers of value for modern technology and service companies.

Company A has total assets of $150 million, which includes factory equipment, inventory, and cash. It also has total liabilities of $90 million, which includes bank loans and accounts payable. The book value of Company A is calculated as $150 million - $90 million = $60 million.
