## Public Offer and Private Placement [Section 23]
A company can issue securities only through the routes permitted to its class.
### Modes of issue available
Public company may issue securities through:
- Public issue through a prospectus, which includes:
- Initial Public Offer (IPO) — first-time offer of shares to public, leading to listing on a stock exchange.
- Further Public Offer (FPO) — additional issue by an already-listed company to raise more funds post-IPO.
- Offer for Sale (OFS) — existing shareholders sell their stake; no new shares are issued, and proceeds go to the sellers, not the company.
- Private Placement
- Rights issue or Bonus issue
Private company may issue securities only through:
- Private Placement
- Rights issue or Bonus issue
> A private company is prohibited from making a public offer — it cannot issue a prospectus inviting the public to subscribe.
### What 'securities' means here
Securities include:
- Equity shares
- Preference shares
- Debentures
- Derivatives
- Actionable claims
- Mutual fund units
Unit-linked insurance policies (ULIPs) are not securities.
