A corporate action is an event initiated by a publicly-traded company that brings material change to the company and impacts its shareholders.
Corporate actions are divided into 3 categories:
- Mandatory events which do not require action from a shareholder. Such events include stock splits, name changes, and stock and cash dividends.
- Voluntary events which require shareholders to elect from a series of options.
- Mandatory with option events which allow a shareholder to make an election; those who do not do so will receive the predetermined default option.
