Book value: what is it?

Book value represents the total value of a company’s tangible and intangible assets after netting out its liabilities. It estimates the total value shareholders would receive if a company were liquidated and all its debts were paid. Book value is typically recorded on a company’s balance sheet as the total of all line items in the shareholders’ equity section.

Book value is used in various financial ratios and can offer insights into a company’s valuation. It’s often compared with a company’s market value to identify when stocks are potentially overvalued or undervalued.

How book value is calculated

Book value is calculated by subtracting a company’s total liabilities from its total assets. The formula is:

Book Value = (Total Current + Non-Current Assets) - (Total Current + Non-Current Liabilities)

Assets include:

• Current assets: Such as cash, short-term investments, accounts receivable, and inventory.
• Non-current assets: Like property, plant, and equipment.
• Intangible assets: These include brand names and intellectual property. Intangible assets can only be included if they’re listed on a company’s financial statements.

Depreciation and amortization are factored into asset values to reflect their reduced worth over time.

Liabilities include all a company’s debts and obligations, including current liabilities (e.g. accounts payable) and long-term liabilities (e.g. debt obligations or deferred taxes). These are subtracted from the company’s total assets.

For example, if a company has total assets of $150 million and total liabilities of $50 million, its book value would be $100 million. This represents the company’s net worth and the equity potentially available to shareholders if the company liquidated its assets and settled its liabilities.

Book value per share

Book value is often expressed per share by dividing shareholder equity by the number of outstanding common stock shares. This metric is commonly used when comparing a company’s book value with its market value to identify potentially overpriced or underpriced shares.

Here’s how to calculate book value per share (BVPS):

BVPS = (Total Shareholder Equity) - (Preferred Stock) / (Total Outstanding Common Shares)

If the company has no preferred stock, the formula can simply divide total shareholder equity by total outstanding shares. Outstanding shares include all shares currently held by shareholders, including those held by institutional investors and restricted shares.

For example, if a company has $60 million in shareholder equity, no preferred stock, and three million outstanding common shares, its book value per share would be $2:

BVPS = $60 million / 3 million = $2.

Investors often compare BVPS with a stock’s current market price:

• If the market price per share is higher than BVPS, it may indicate a potentially overvalued stock.
• If the market price per share is below BVPS, it may indicate a potentially undervalued stock.

However, these observations shouldn’t be taken as definitive indicators of value. Market price discrepancies may result from factors not reflected in book value, such as growth potential, market conditions, or the company’s industry.

Price-to-book ratio

The price-to-book (P/B) ratio compares a company’s book value to its market value.

Here’s how to calculate P/B ratio:

P/B = (Market Capitalization) / (Book Value)

For example, a company has $5 million in assets and $2 million in liabilities. It has 100,000 outstanding shares at $40 per share. Here’s how you would calculate its P/B ratio:

• Book Value = 5 million - 2 million = 3 million
• Market Capitalization = 40 x 100,000 = 4 million
• P/B = 4 million / 3 million = 1.33

The role of book value in assessing a company’s financial health

Book value provides a tangible representation of a company’s net worth and is used in financial ratios used to assess certain aspects of financial health. These include:

• Debt-to-Equity Ratio: This ratio incorporates book value to evaluate the portion of shareholder equity and debt used to fund a company’s assets.
• Return on Equity (ROE): This ratio measures how effectively a company uses its equity to generate profits, using book value to relate to net income.

These ratios help evaluate how effectively a company manages its assets, liabilities, and cash flow while generating returns. Investors and analysts use these ratios to understand how well a company manages its assets and liabilities while generating returns for shareholders.

Book value vs market value: key differences for investors

Book value and market value are both used to assess a company’s worth, however they are calculated differently and serve distinct purposes.

Book value

Book value represents a company’s net worth based on its financial statements. It’s calculated by taking the total value of a company’s assets and subtracting its liabilities. Theoretically, book value indicates how much equity shareholders would receive if a company were liquidated.

For example, if a company reported total assets of around $200 billion and total liabilities of $100 billion, it would have a book valuation of $100 billion ($200 billion - $100 billion). This figure is often reported on balance sheets as total shareholders’ equity.

Market value

Market value (also known as market capitalization or market cap) reflects a company’s value as determined by the stock market. It’s calculated by multiplying the current stock price by the total number of outstanding shares.

Market Value = (Current Stock Price) x (Total Number of Outstanding Shares)

Market value reflects investor sentiment on a company’s profitability and growth potential. It’s what most investors, financial reporters, and analysts refer to when they speak about a company’s value.

For example, if a company trades at $15 per share and has 2 million shares outstanding, its market value is $30 million ($15 x 2 million).

Because share prices change throughout the day, so does a company’s market value. This means market value can constantly fluctuate with per-share price shifts.

There can be big disparities between a company’s book value and market value. This is because book value relies solely on historical financial data while market value considers future growth potential, profitability, and other intangible factors.

How institutional investors use book value in valuation and decision-making

Institutional investors commonly use book value to guide valuation and investment strategies, particularly in value investing. Below are some ways investors consider book value.

Find undervalued stocks

Book value can be used to highlight when stocks are potentially undervalued. Investors compare a company’s book value per share (BVPS) to its current market price per share to analyze discrepancies between the two metrics.

Investors may also consider a stock’s price-to-book (P/B) ratio. Low P/B ratios below 1 can signal a potentially undervalued stock, which happens when a company’s market capitalization is lower than its book value. Higher P/B ratios could suggest an overvalued stock. That said, there is no ‘ideal’ number and several factors can impact a company’s P/B ratio.

Evaluate earnings power

Investors also use book value to evaluate a company’s earnings potential. Companies with high book values relative to their market value may indicate untapped earnings power.

Constructing a margin of safety

Book value plays a role in the margin of safety principle, which value investors use to protect against overpaying. Investors often aim to buy stocks priced below their book value to provide a buffer against potential losses.

Compare market value to book value

Investors often analyze the discrepancy between a company’s book value and market capitalization to gain insights into a stock’s value:

• If market cap is higher than book value: This can indicate high future earnings potential that isn’t yet reflected on financial statements. However, it can also suggest more downside risk.
• If market cap is close to or below book value: This can indicate untapped earnings power and assets, suggesting upside potential with less downside risk.

The limitations of using book value

Although book value is widely used by investors and analysts, it has certain limitations that can make it an incomplete measure of a company’s true worth. These include:

Excluding tangible assets

Book value doesn’t accurately consider intangible assets like patents, intellectual property, brand value, and goodwill.

For example, a technology company’s primary value may lie in its app designs and patents – assets that are not typically reflected in book value. Because market cap takes intangible assets into account, the company's stock may trade higher than its book value.

To navigate this limitation, it’s important for investors to consider a company and its industry when comparing book value with market value.

Lacking real-time accuracy

Book value is reported on a company’s balance sheet quarterly or annually, which means investors may be accessing outdated information in between reporting periods.

Basing decisions on past figures can lead to inaccurate analysis, particularly in fast-moving markets. Any sudden changes in asset value, market conditions, or company performance won’t be reflected until the next reporting cycle.

Not accounting for human capital

Book value can vary significantly between asset-heavy companies and those that rely on human capital. For example, manufacturing or real estate companies tend to have higher book values because they possess tangible assets like machinery or land.

On the other hand, companies in gaming, software, or creative industries may have lower book values, despite strong profitability and market performance. The success of these companies relies on the skills, expertise, and intellectual contributions of their employees, however this is not something that can be captured on financial statements. Book value may not be an appropriate measure in these cases.

Since book value reflects a company’s underlying net worth, understanding broader economic trends is essential; the Global Macro Insights by Vincent Deluard subscription delivers forward-looking analysis that helps investors interpret how shifts in the economy may impact asset values and investment opportunities.
