A corporate action is an activity initiated by a company that materially affects the company and its shareholders. Corporate action events can substantially impact the value of shares, bonds, or other financial instruments issued by a company. There are over 70 different types of corporate actions. Some of the most common ones are:
- Dividends
- Stock splits
- Mergers and acquisitions
- Rights issues
- Spinoffs
- Increases and reductions of capital stock
A distinction is drawn between two kinds of corporate actions: mandatory ones executed without express approval by shareholders, and voluntary ones in which shareholders have the option of taking part.
