Components of common stock book value:
- Par value: Nominal value assigned to shares (often minimal, like $0.01)
- Additional paid-in capital: Amount paid above par value when shares were issued
The calculation:
Common Stock (Book) = Par Value × Shares Issued + Additional Paid-in Capital
Why book value matters:
- Equity foundation: Represents capital originally invested by shareholders
- Historical record: Shows cumulative equity issuances over time
- Balance sheet component: Part of total shareholders' equity
- Dilution tracking: Changes indicate new share issuances
Book vs. market value:
- Book value: Historical cost of equity raised; rarely changes after issuance
- Market value: Current share price times shares outstanding; fluctuates constantly
- Price-to-book ratio: Compares market value to book value per share
Analysis considerations:
- Share issuances: Increases in common stock mean new shares were sold
- Stock-based compensation: Option exercises add to common stock
- Par value irrelevance: Modern par values are usually nominal and uninformative
