A corporate action is an event initiated by a public company that affects the securities (equity or debt) issued by the company. Some corporate actions such as a dividend (for equity securities) or coupon payment (for debt securities) may have a direct financial impact on the shareholders or bondholders; another example is a call (early redemption) of a debt security. Other corporate actions such as stock split may have an indirect impact, as the increased liquidity of shares may cause the price of the stock to decrease. Some corporate actions such as name change have no direct financial impact on the shareholders. Corporate actions are typically agreed upon by a company's board of directors and authorized by the shareholders. Some examples are stock splits, dividends, mergers and acquisitions, rights issues and spin offs.
