Generally speaking, the amount of capital invested by investors refers to paid-in capital or share capital (joint-stock company), excluding capital reserve. Limited companies and joint-stock companies do not include capital companies, because capital reserve may be the premium part of shareholders' investment, but it also includes changes in the fair value of equity investment.
Therefore, if it is generally not included, it can only be paid-in capital or equity. If included, it can only be the share premium part of capital reserve at most.
The invested fixed assets, if not verified by capital increase, are also included in the capital reserve.
