Preferred shares, also known as preference shares or simply "prefs", are a class of shares in a company that have certain rights and privileges that distinguish them from common shares. Preferred shares typically have a fixed dividend rate, which is paid to the shareholder before any dividends are paid to common shareholders. This fixed rate provides a more stable income stream for investors and can be attractive to income-oriented investors. In addition, preferred shares usually have priority over common shares in the event of a company's liquidation or bankruptcy, which means that preferred shareholders would receive their capital back before common shareholders. There are also different types of preferred shares, such as cumulative and non-cumulative, convertible and non-convertible, participating and non-participating, and callable and non-callable. While preferred shares can offer benefits such as stability and priority over common shares, they also have some drawbacks. For example, the fixed dividend rate may not keep up with inflation or changes in interest rates, and the priority in liquidation or bankruptcy may not guarantee a full return of capital. In addition, the lack of voting rights for preferred shareholders may limit their ability to influence company decisions. Overall, preferred shares can be a useful tool for investors and companies alike, providing stable income and priority in the event of a company's liquidation or bankruptcy. However, they also require careful consideration of their features and risks to ensure they are a suitable investment for a particular investor's goals and risk tolerance.
