What is Capital Stock?
Capital stock is the common stock and preferred stock that a company is allowed to issue according to its corporate charter. Common and Preferred stock can be separated into different classes of stock with their own features. In accounting, capital stock is one part of the equity section on a balance sheet.' Only corporations can sell capital stock to investors.
Capital stock is not necessarily equal to the number of shares that are currently outstanding. It is the maximum number of shares that can ever be outstanding. If a company wants to change this number, they have to change it on their charter. This is done with a vote. When companies do this, it is usually so that they can raise more capital.
To find the value of capital stock, also called share capital, you follow a simple equation:
Capital Stock = Number of shares issued x Par Value per share
For example: If a company has issued 1,000 shares at a price of $5 per share, the capital stock value would be $5,000.
It is important to note that par value is a set dollar amount assigned to each common share. Any amount paid by investors above the par value is noted in the accounting books under additional paid in capital.
The amount of capital stock can never be more than the amount of' authorized stock.
Why is Capital Stock Important?
Capital stock is the way a company raises money to expand the business. An investor can buy stock from a corporation and in return they hope to receive benefits known as dividends.
Companies can also issue stock in exchange for assets like buildings, land or equipment that they need for their business.
The amount of capital stock issued to different people, whether investors or shareholders, decides the percentage of the company that each person owns. For example, if there are 10,000 shares of capital stock and an investor owns 5,000 stocks, he owns 50 percent of the company.
What are the Advantages of Capital Stock?
- The biggest advantage to selling capital stock is that a company does not need to take out debt in order to finance new projects. If a company needs more money to grow, instead of taking out a loan that they will have to pay back with interest, they can sell capital stock.
- It also allows them to make more money than they may have been able to get if they had to take out a loan.
What are the Disadvantages of Capital Stock?
- By selling capital stock to investors, a company is giving up some of its equity.
- The more capital stock that gets issued, the more diluted the value of each share becomes.
The Differences Between Common and Preferred Stock
Preferred stockholders have a few more benefits that common stockholders. If a company liquidates (whether it is bought or goes bankrupt), the preferred stockholders will receive a payout before the common stockholders. They also receive different dividends than common stockholders, usually more.
Capital Stock vs. Market Capitalization
It's important not to confuse capital stock with market capitalization.
- Capital stock refers to the book value of issued shares based on par value.
- Market capitalization is the current market value of a company, calculated by multiplying outstanding shares by the stock price.
For instance, a company might have $10,000 in capital stock but a market cap of $1 million. This distinction matters for investors analyzing corporate financial health and growth potential.
Legal Framework and Regulatory Compliance
Issuing capital stock must comply with state corporate laws and SEC regulations (for public companies). The corporate charter outlines the classes of stock, voting rights, and authorized share limits. Before issuing additional stock, corporations may require:
- Shareholder approval for amending the charter,
- Regulatory filings (e.g., Form S-1 with the SEC),
- Proper valuation and board resolutions.
Failing to comply can result in legal liability, disputes among shareholders, or invalid issuance.
Accounting for Capital Stock on the Balance Sheet
In accounting, capital stock is reported in the shareholders' equity section of a balance sheet. It typically includes:
- Common stock and preferred stock, listed at par or stated value.
- Additional Paid-In Capital (APIC), representing the excess amount paid by investors over par value.
The formula remains:
Capital Stock Value = Issued Shares × Par Value
For example, if 1,000 shares are issued at $1 par value and sold at $5, the capital stock value is $1,000, and APIC is $4,000.
Authorized vs. Issued vs. Outstanding Capital Stock
Corporations must distinguish between:
- Authorized stock: The maximum number of shares the company can legally issue, as defined in its charter.
- Issued stock: The number of shares that have been distributed to shareholders.
- Outstanding stock: Issued stock that remains in circulation, excluding treasury shares (reacquired by the company).
These terms affect financial reporting, shareholder equity, and a company’s capacity to raise additional funds through stock issuance.
How Capital Stock Affects Ownership and Voting Rights
Capital stock determines not just ownership but the degree of control shareholders have in corporate decisions. Common stockholders typically have voting rights, enabling them to elect directors and influence major policy decisions. Preferred stockholders, while often lacking voting power, enjoy priority in dividends and liquidation payouts.
The number of shares issued impacts control. For example, if a founder initially owns 100% of the capital stock but later issues shares to investors, their ownership percentage—and influence—declines. This dilution is a key consideration in structuring financing rounds or employee equity compensation.
