Common stock is the basic class of equity ownership in a corporation. It carries voting rights and the full upside of the business, but its claim on earnings and assets is residual; common shareholders are paid last, after creditors and preferred stockholders. That residual position is what the worked exit example below quantifies in dollars.

This guide covers what common stock is, the rights common shareholders hold, how common shares appear on the balance sheet, the main types and share classes, and a worked example showing what “residual” actually costs a common holder at exit.

The short version:

  • What it is: the basic ownership class of a corporation, also called common shares or ordinary shares.
  • Rights: voting, a residual claim on dividends, and a residual claim on assets at liquidation or exit.
  • Priority: last in line: behind creditors, bondholders, and all preferred stock.
  • Who holds it: in private companies, founders and employees hold common; investors hold preferred.
  • Why “residual” matters: common’s ownership percentage and its actual exit payout can differ sharply once preferences are paid.

What is common stock?

Common stock is a unit of equity ownership in a corporation. A holder of common stock is a shareholder (a part-owner of the company) and is also described as a common stockholder. Every ranking definition agrees on three attributes: common stock confers an ownership stake, it usually carries voting rights, and it holds a residual claim on the company’s earnings and assets.

In public companies, common stock is the most widely issued form of equity, bought and sold on exchanges. In private companies, the same class is typically held by founders and employees (directly as shares or through stock options) while outside investors hold preferred stock. Common and preferred are both equity, but they are different securities with different rights, and they are rarely worth the same amount per share.

What rights do common shareholders have?

Common shareholders hold a defined set of rights. The specifics depend on the company’s charter and jurisdiction, but four categories are standard.

Voting rights

Common stock typically carries one vote per share. Common shareholders elect the board of directors and vote on major corporate actions such as mergers, charter amendments, and significant share issuances. Voting power can be altered by the capital structure: some companies issue more than one class of common stock with different voting weights, covered in the types section below.

Residual claim on earnings (dividends)

Common shareholders have a claim on the company’s profits, paid as dividends. Those dividends are discretionary (declared at the board’s discretion) and variable in amount. They are paid only after any preferred dividends are satisfied. “Residual” here means common receives whatever earnings are distributed after senior claims, not a fixed or guaranteed amount.

Residual claim on assets (liquidation and exit)

If the company is sold, wound down, or liquidated, common stock is last in line. Creditors and bondholders are paid first, then all preferred stock through its liquidation preference, and common shareholders split only what remains. This last-place priority is the defining economic feature of common stock, and it is the basis for the worked example below.

Preemptive and other rights

Where the charter or governing law provides them, common shareholders may hold preemptive rights (the right to buy newly issued shares to maintain their proportional ownership), along with information and inspection rights. These vary by jurisdiction and by the company’s organizing documents, so they are not universal.

Common stock on the balance sheet

On the issuing company’s balance sheet, common stock is a component of shareholders’ equity. It is typically recorded at par value (a nominal figure such as $0.0001 per share) with the amount investors paid above par recorded separately as additional paid-in capital (APIC). The common equity attributable to shareholders is itself a residual figure: total assets minus total liabilities minus the claims of preferred stock. In formula terms, the common stock line equals shares issued multiplied by par value, while the broader common equity is the residual of the accounting equation (assets − liabilities − preferred claims). For the holder, by contrast, the same shares are an asset they own.

Types and examples of common stock

Common stock varies along a few dimensions. Shares may be voting or non-voting. A company may have a single class of common, or a dual- or multi-class structure in which different classes (commonly labeled Class A and Class B) carry different voting weights, often to let founders retain control after raising capital. Common stock may also be publicly traded on an exchange or held privately in a closely held company. For the mechanics of multiple classes and how dual-class voting is structured, see Class A vs Class B shares. Specific company tickers are omitted here, as naming them is not an endorsement.

What “residual” means at exit: a worked example

The rights sections above state that common stock is last in line. This section shows, in dollars, what that means. The gap it reveals is the reason “residual” is not a technicality.

Setup. A company is acquired for $20,000,000.00. Its cap table is simple: a Series A investor put in $10,000,000.00 for 40% of the company on a 1x non-participating liquidation preference. Founders and employees hold the remaining 60% in common stock.

The naive, ownership-only read. Common owns 60% of the company, so 60% of a $20,000,000.00 sale looks like $12,000,000.00.

The actual waterfall. A 1x non-participating preference lets the preferred holder take the greater of (a) its preference or (b) what its ownership percentage would yield by converting to common:

  • Preference amount: $10,000,000.00.
  • Converted-to-common amount: 40% × $20,000,000.00 = $8,000,000.00.

The preferred takes the greater figure: its $10,000,000.00 preference. Common stock then splits the residual:

  • $20,000,000.00 − $10,000,000.00 = $10,000,000.00 to common.

So common receives $10,000,000.00, not the $12,000,000.00 its 60% ownership suggested. The $2,000,000.00 difference is the cost of being residual.

The takeaway. “Residual” is the gap between what common’s ownership percentage implies and what common actually receives once preferences are paid. That gap is exactly what an exit distribution waterfall computes across every share class, using each class’s liquidation preference and conversion terms. Tools like Waterfalls model this for a full cap table, so the residual figure is computed rather than estimated.

Common stock vs preferred stock (in one minute)

Preferred stock is the senior class: it is generally paid first through its liquidation preference, can carry priority or fixed dividends, and is often non-voting. Common stock sits below it, carrying voting rights and unlimited upside, but bearing the residual risk of being paid last at every distribution. The same ownership percentage can translate into very different dollars depending on the preference terms stacked above it, as the example above shows. A full side-by-side (priority, dividends, voting, conversion, and a worked exit comparison) is laid out in preferred stock vs common stock.

Frequently asked questions

What is common stock in simple terms?

Common stock is the basic ownership share of a corporation. Holding it makes you a part-owner with voting rights and a claim on profits and growth. That claim is residual, though; common shareholders are paid last, after creditors and preferred stockholders.

What is another name for common stock?

Common stock is also called common shares, ordinary shares, or voting shares. In private companies it is the class typically held by founders and employees, while investors hold preferred stock. The terms describe the same residual, voting ownership class.

Is common stock an asset or equity?

It depends on the perspective. For the shareholder, common stock is an asset they own. On the issuing company’s balance sheet it is equity, recorded at par value, with amounts above par in additional paid-in capital. Common equity is the residual after liabilities and preferred claims.

Why would you buy common stock?

Common stock offers voting rights and unlimited upside: its value rises with the company, capturing growth that preferred stock’s fixed terms usually cap. The trade-off is risk: common is last in line for dividends and at liquidation or exit.

How do common and preferred stock differ at exit?

At a sale, preferred stock is paid first through its liquidation preference; common stock splits only the residual that remains. The same ownership percentage can yield very different dollars depending on the preference terms, which is what a distribution waterfall calculates.
