Definition
Book Value
A company's accounting net worth (shareholders' equity) per common share, calculated as (total assets minus total liabilities minus preferred stock at par or liquidation value) divided by common shares outstanding. Tangible book value per share, also called net tangible worth per share, goes further and also subtracts intangible assets such as goodwill. Commonly used in the price-to-book (P/B) ratio to assess whether a stock is overvalued or undervalued relative to its accounting value.
A company with $500 million in total assets (including $50 million in intangibles), $200 million in liabilities, no preferred stock, and 20 million shares outstanding. Tangible assets = $500M - $50M = $450M. Tangible book value per share = ($450M - $200M) ÷ 20M shares = $12.50. If the stock trades at $25, the P/B ratio on a tangible basis is 2.0 ($25 ÷ $12.50), meaning investors pay $2 for every $1 of tangible book value.
Book value reflects accounting (historical) values, not current market values. A stock trading below book value is not automatically undervalued: the company may have declining assets, obsolete inventory, or poor earnings prospects. Book value is most meaningful for asset-heavy industries (banks, real estate) and less relevant for technology or service companies with significant intangible assets.
How is Book Value tested on the exam?
- Calculating tangible book value per share using tangible assets minus liabilities minus preferred stock, divided by common shares
- Identifying which assets count as tangible (excluding goodwill, patents, intangibles)
- Determining whether a stock is trading above or below book value using the P/B ratio
- Understanding when book value is meaningful (asset-heavy industries) versus when it is not (intangible-heavy companies)
- Recognizing that book value uses historical cost accounting, not current market value
Calculation example
Calculation Example
Tangible Book Value per Share = (Total Assets - Intangibles - Total Liabilities - Preferred Stock) ÷ Common Shares - Identify total assets: $750 million
- Identify intangible assets (goodwill, patents, etc.): $100 million
- Calculate tangible assets: $750M - $100M = $650 million
- Identify total liabilities: $450 million
- Identify preferred stock (at par or liquidation value): $0 (none outstanding)
- Calculate tangible book value: $650M - $450M = $200 million
- Identify common shares outstanding: 25 million
- Calculate tangible book value per share: $200M ÷ 25M = $8.00 per share

| Tangible book value per share calculation formula | (Total Assets - Intangibles - Total Liabilities - Preferred Stock) ÷ Common Shares | Uses tangible assets only; excludes goodwill, patents, and other intangibles. Also called net tangible worth per share. Subtracts preferred stock at par or liquidation value. |
| Price-to-Book (P/B) ratio | Market Price per Share ÷ Book Value per Share | P/B < 1 means the stock trades below book value; P/B > 1 means above book value |
Think of tangible book value as the tangible accounting report card. Tangible Book Value per Share = (Tangible Assets - Liabilities - Preferred Stock) ÷ Common Shares, the balance sheet value left for common shareholders after liabilities and preferred stock, not a liquidation value. Excludes intangibles like goodwill. Remember: uses historical costs, not current market prices. A stock trading below book value might be a value trap if assets are declining; always ask why the market disagrees with the books.
Practice questions
Test your understanding with the questions below. Pick an answer to reveal the explanation.
Robert, a value investor, is analyzing two regional banks. Bank A has a book value per share of $40 and trades at $50 (P/B of 1.25). Bank B has a book value per share of $35 and trades at $28 (P/B of 0.80). Both banks have similar earnings and dividend yields. Robert believes Bank B is undervalued because it trades below book value. Which statement about this analysis is most accurate?
B is correct. A stock trading below book value (P/B < 1.0) is not automatically undervalued. Bank B may trade at a discount to book value due to legitimate concerns such as declining asset quality, potential loan losses, regulatory issues, or poor earnings prospects. Value investors must investigate why the market is pricing the stock below its accounting value before concluding it is undervalued.
A is incorrect because trading below book value alone does not guarantee undervaluation; the market may be correctly pricing in fundamental problems. C is incorrect because book value is actually very relevant for financial institutions, which are asset-heavy businesses where tangible assets (loans, securities) dominate the balance sheet. D is incorrect because absolute book value per share does not determine value; what matters is the P/B ratio and the quality of the underlying business.
The Series 65 exam tests your ability to apply book value analysis appropriately, recognizing when it is meaningful (asset-heavy industries like banks, real estate, manufacturing) versus when it is less relevant (technology, services with intangible assets). Understanding that book value is just one valuation metric, not a guarantee of value, is critical for making sound investment recommendations.
What does a company's book value represent?
B is correct. Book value is the accounting net worth of the company: total assets minus total liabilities, which equals shareholders' equity on the balance sheet. Book value per common share goes further, subtracting preferred stock at par or liquidation value (and, in the tangible version, intangible assets such as goodwill) and dividing by common shares outstanding.
A is incorrect; market capitalization is the current stock price multiplied by shares outstanding, reflecting market value, not accounting (book) value. C describes earnings per share (EPS), not book value. D is incorrect because book value uses historical balance sheet values, not the liquidation value of the company's assets, and it subtracts liabilities rather than counting physical assets alone.
The Series 65 exam frequently tests the definition of book value and its calculation. Understanding that book value represents the accounting-based net worth of a company (not market value) is fundamental to using valuation metrics like the price-to-book ratio correctly.
A corporation has total assets of $960 million, total liabilities of $540 million, and 30 million shares outstanding. What is the book value per share?
A is correct. Calculate: Book Value = Total Assets - Total Liabilities = $960M - $540M = $420M. Book Value per Share = $420M / 30M shares = $14.00 per share.
B ($18.00) results from a calculation error (perhaps $540M / 30M instead of the correct formula). C ($32.00) incorrectly uses only assets: $960M / 30M = $32. D ($50.00) adds liabilities to assets instead of subtracting them: ($960M + $540M) / 30M = $50. The critical steps are: (1) subtract liabilities from assets to get book value, then (2) divide by shares outstanding.
Book value per share calculation questions appear regularly on the Series 65 exam. You must accurately apply the two-step formula: first calculate book value (Assets - Liabilities), then divide by shares outstanding. Avoid the common error of dividing assets by shares without first subtracting liabilities.
All of the following statements about book value are accurate except
C is correct (the exception). A stock trading below book value (P/B ratio < 1.0) is not always undervalued. The market may be correctly pricing in legitimate concerns such as declining asset values, obsolete inventory, poor earnings prospects, or industry headwinds. Book value is an accounting measure based on historical costs, not current market conditions. Further analysis is required before concluding a below-book-value stock is undervalued.
A is accurate: book value equals shareholders' equity, calculated as assets minus liabilities. B is accurate: book value per share is indeed total book value divided by shares outstanding. D is accurate: book value is most meaningful for companies with significant tangible assets (banks hold loans and securities; manufacturers have equipment and inventory), and less relevant for service or technology companies where intangible assets (brand value, intellectual property) dominate.
The Series 65 exam tests whether you understand the limitations of book value analysis. Knowing that trading below book value is not an automatic buy signal demonstrates sophisticated understanding of fundamental analysis and helps you avoid simplistic valuation mistakes when advising clients.
A technology company has total assets of $800 million (of which $600 million are intangible assets like patents and goodwill), total liabilities of $300 million, and 25 million shares outstanding. The stock currently trades at $40 per share. Which of the following statements are accurate?
1. The company's book value, including intangibles, is $500 million
2. The book value per share, including intangibles, is $20
3. The P/B ratio on that basis is 2.0
4. Book value is likely a highly reliable valuation metric for this company
C is correct. Statements 1, 2, and 3 are accurate.
Statement 1 is true: Book value including intangibles = Total Assets - Total Liabilities = $800M - $300M = $500 million.
Statement 2 is true: Book Value per Share = $500M / 25M shares = $20 per share.
Statement 3 is true: Price-to-Book Ratio = Market Price / Book Value per Share = $40 / $20 = 2.0. Investors are paying $2 for every $1 of book value.
Statement 4 is false: Book value is not a reliable valuation metric for this technology company because 75% of its assets ($600M of $800M) are intangible. Its tangible book value is negative: $800M - $600M - $300M = -$100 million. Intangible assets like goodwill, patents, and intellectual property are carried at historical cost and may be worth significantly more or less than their balance sheet values. Book value works best for asset-heavy industries (banks, manufacturing, real estate) where tangible assets dominate. For technology companies, metrics like P/E ratio, revenue growth, and cash flow are typically more meaningful.
The Series 65 exam tests your ability to both calculate book value metrics and recognize when book value is an appropriate valuation tool. Understanding that book value has limited usefulness for companies with significant intangible assets (technology, brands, services) demonstrates sophisticated fundamental analysis skills critical for making sound investment recommendations.
