Do Split Stocks Count Against Authorized Shares?
Reverse stock splits don't affect the number of authorized shares, but a forward stock split issues new stock from the company's authorized shares. When new shares are issued by a company, it adds to the number of outstanding shares and reduces each shareholder's percentage of ownership in the company. This is called dilution, and it reduces the value of each share. Authorized shares represent a potential for stock dilution
