We have discussed earlier post The Company under the Companies Bill 2012 which is still relevant when the bill become Act; all companies do not have share capital. Only companies limited by shares have share capital.
KIND OF SHARE CAPITAL (SECTION 43):
The share capital of companies limited by share shall be of two kinds, namely;
(a) equity share capital;
(b) Preference share capital.
Here, use of two terms “Shall be” and “and” denote this is a requirement to have both kind of share capital but, according to further reading, company may have zero equity or preference share capital.
