At the time of incorporation, the directors must determine the nominal value of each share, which the shareholder must pay the company. The initial capital in the company is simply the number of shares multiplied by the nominal value of each share. A high nominal value means founders must put a large amount of capital into the company. As time progresses and more shares are issued, they’ll have the same nominal value but may be issued at a premium to that, reflecting an increase in the overall value of the company.
