What is an Offer for Sale (OFS)?
An Offer for Sale (OFS) is a streamlined method for selling shares of listed companies through the exchange platform. Introduced by the Securities and Exchange Board of India (SEBI) in 2012, the mechanism was designed to help promoters of publicly-traded companies reduce their holdings and meet the minimum public shareholding norms.
Recent Development in OFS – Rail Vikas Nigam Ltd (RVNL)
The government’s 5.36% stake sale in Rail Vikas Nigam Ltd (RVNL) under the Offer for Sale (OFS) mechanism witnessed a strong response from institutional investors. This move aligns with the government’s strategy to divest its holdings in public sector enterprises, ensuring compliance with market regulations while promoting wider public participation in stock markets.
Purpose of OFS
- Allows promoters to dilute their stake in listed companies.
- Helps companies comply with SEBI’s minimum public shareholding rules.
- Used as a disinvestment tool by the government to offload shares in Public Sector Enterprises (PSEs).
- Facilitates wider investor participation, including retail and institutional investors.

Why Did SEBI Introduce OFS?
- SEBI introduced the OFS mechanism to:

- Ensure companies meet the minimum 25% public shareholding rule.
- Provide faster and more transparent share sale methods.
- Assist the government in disinvesting shares in Public Sector Enterprises (PSEs).
Recent Example: SEBI-Regulated OFS in RVNL
The Indian government recently conducted an OFS to sell a 5.36% stake in Rail Vikas Nigam Ltd (RVNL). The offer received a strong response from institutional investors, demonstrating the efficiency of SEBI’s OFS framework.
Difference Between OFS and FPO
Aspect | Offer for Sale (OFS) | Follow-on Public Offering (FPO) |
---|---|---|
Nature of Shares | Only existing shares are sold | Companies can issue new shares and/or promoters can sell existing shares |
Purpose | Used primarily for stake dilution | Used for fundraising and capital expansion |
Who Can Sell? | Only promoters or major shareholders (10%+ stake) | Both companies and promoters can sell shares |
Process Complexity | Simpler, faster, and conducted via stock exchange | Requires longer regulatory approval and book-building process |
Investor Base | Open to institutional and retail investors | Open to public investors through book-building or fixed price method |
Why is the Government Using OFS for Disinvestment?
- The Indian government frequently uses OFS as a disinvestment tool to sell its stake in public sector enterprises (PSEs). This approach is beneficial because:
- Faster Execution –
- OFS transactions happen quickly compared to IPOs or FPOs.
- Market-driven Pricing –
- Share prices are determined based on demand and investor participation.
- Higher Transparency –
- Conducted via stock exchanges, ensuring fair and transparent pricing.
- Encourages Retail Participation –
- Reservations for retail investors allow broader participation in government-owned companies.
