I usually advise companies to authorize around 10 to 15 million shares of common stock. Around 8 or 9 million shares are issued to founders.The total authorized number of shares of the corporation is 6,005,000,000. This somewhat complicated annual franchise tax can be calculated two different ways: the Authorized Shares Method and the Assumed Par Value Capital Method. "Authorized shares" refers to the number of shares the corporation is allowed to issue under its certificate or articles of incorporation. There is a difference between "authorized" shares and "issued" shares. The statement shall contain: (a) the name of the corporation;. Issued and Outstanding Shares. Complete information about investing in shares of BREIT is available in the prospectus. A corporation may not issue any more shares than have been previously authorized.
