A Certificate of Directors' Resolution to Change Capitalization is a legal document that is issued by a board of directors in order to authorize a change in the capitalization of a business entity, such as a corporation or limited liability company. This document is used to document the board's approval of a change in the amount of the company's authorized capital stock, as well as the number of shares of each class or series. The Certificate of Directors' Resolution to Change Capitalization may also be referred to as an increase in capital stock resolution. There are two main types of Certificate of Directors' Resolution to Change Capitalization: (1) Stock Increase Certificate, which is used to authorize an increase in the number of authorized shares of a company; and (2) Stock Split Certificate, which is used to authorize a division of a company's existing stock into multiple classes or series.
