Increase / Decrease in Capital of Private Limited Company.

Ans A: Authorised Share Capital of a Public Company may be increased by passing a special resolution but for Private Company I believe it is a Unanimous Resolution that is required to be passed in their AGM's.
Ans B: Increasing the issued capital in case of a company is governed by section-62 of the Act and shares may be issued to existing shareholders of the said company. As far as decreasing the same is concerned it is governed by section-66 of the Act, in which a process is stipulated for the same.
