Common stock typically represents ownership in a corporation and gives the shareholder voting rights at shareholder meetings. The structure of common stock includes:

1. Par value: This is the nominal value of the stock, which is typically set at a low amount such as $0.01 or $0.10.

2. Authorized shares: This is the maximum number of shares that a corporation can issue.

3. Issued shares: This is the number of shares that have been issued and are currently outstanding.

4. Outstanding shares: This is the number of shares that are currently held by shareholders.

5. Dividends: Common stockholders may receive dividends, which are payments made by the corporation to its shareholders.

6. Liquidation preference: In the event of a liquidation or bankruptcy, common stockholders are typically the last to receive any remaining assets after all other creditors and preferred stockholders have been paid.

7. Rights and privileges: Common stockholders have the right to vote on important company decisions, such as the election of the board of directors and major corporate actions. They also have the right to attend shareholder meetings and receive annual reports.
