Share capital refers to the capital raised by a company through the issuance of shares to its shareholders. There are several types of share capital, each with its own characteristics and implications. Here are the different types of share capital:

Authorized Share Capital: This is the maximum amount of capital that a company is authorized to issue to its shareholders as per its memorandum of association. It represents the total value of shares the company can legally issue.

Issued Share Capital: Issued share capital is the portion of authorized share capital that the company has actually issued to shareholders. These are the shares that are held by shareholders and are in circulation.

Subscribed Share Capital: Subscribed share capital represents the portion of issued share capital that shareholders have agreed to purchase or subscribe to. Shareholders may not always subscribe to the full amount of shares issued to them.

Paid-up Share Capital: This is the amount of money received by the company from shareholders for the shares they have subscribed to. It represents the actual capital received by the company. If a company issues shares with a face value of ₹100, and shareholders have paid ₹50 per share, the paid-up share capital is ₹50 per share.

Unpaid Share Capital: Unpaid share capital is the amount that shareholders have agreed to pay but have not yet paid. This is a liability on the balance sheet until the shareholders make the payments.

Common Share Capital: Common shares, also known as ordinary shares, are the most common type of shares. They typically carry voting rights and a share in the profits of the company.

Preferred Share Capital: Preferred shares are a type of share capital that gives shareholders certain preferential rights over common shareholders. These rights may include a fixed dividend, priority in receiving assets in case of liquidation, and no voting rights.

Equity Share Capital: Equity shares represent the ownership interest in a company. Equity shareholders have voting rights and share in the company's profits. They are the true owners of the company and bear the most risk.

Preference Share Capital: Preference shares are a type of share capital that provides preferential rights to shareholders in terms of receiving dividends and the distribution of assets in case of liquidation. They usually do not carry voting rights.

Bonus Share Capital: Bonus shares are issued by a company to its existing shareholders without any consideration, often as a way to distribute accumulated profits or reserves. They do not involve a cash outflow from shareholders.

Sweat Equity Share Capital: Sweat equity shares are issued to employees or directors of a company as a form of compensation for their services or contributions to the company. These shares are typically issued at a discount or for no consideration.

Rights Share Capital: Rights shares are issued to existing shareholders in proportion to their current shareholding. Shareholders have the right to subscribe to these shares, usually at a discounted price, before they are offered to others.

Each type of share capital has distinct features and implications, and the choice of share capital structure can vary depending on the company's capital needs, objectives, and legal requirements.
