According to the charter, the size of the authorized capital of an AA must be 600 thousand dollars and divided into 60 thousand ordinary shares with a par value of 10 dollars each. In order to pay for the shares, the founders undertook: Angles (2000 shares) and Koshkin (1500 shares) - to prepare the necessary documents and register the joint-stock company, as well as to give permission to use their name in the name of Green Etil JSC. by open subscription.
During the discussion, Angles offered to issue two types of shares: face value of $ 10 for founders and $ 200 for all other shareholders. So that each share would have one vote. Koshkin demanded that the JSC’s charter pre-emption rights for the shares sold by other shareholders. M noted that it is necessary to create a supervisory board in the joint-stock company, since after the open subscription the number of shareholders will be very large.
