An Offer for Sale (OFS) is a mechanism that allows promoters or major shareholders of listed companies to offload shares directly through the stock exchange. Launched by SEBI in 2012, it was designed to help promoters lower their holdings and comply with minimum public shareholding norms transparently. This route is used by both government-owned and private companies and is accessible to institutional investors, retail participants, and mutual funds. This blog explains the meaning of OFS, its process, and its key characteristics.

 

What is Offer For Sale (OFS) in Share Market?

An Offer for Sale (OFS) lets a company, or its main shareholders sell shares to the public. It is used to raise money, with promoters selling shares to regular investors, companies, and big institutions on the stock exchange.

How does an Offer for Sale work?

Here is a simple step-by-step guide explaining how the OFS process works, from the company’s initial announcement through to the final allotment of shares:

  1. Announcement: The seller publicly announces the OFS and specifies a minimum price, known as the floor price, for the shares being sold. This information is disclosed on the stock exchange platform.
  2. Bidding: During the bidding period, investors place bids for the shares. These bids must meet or exceed the declared floor price to be considered valid.
  3. Allocation: After the bidding period closes, the seller evaluates all bids and decides how many shares will be allocated to each bidder based on their offers.
  4. Settlement: Shares are credited to the successful bidders’ demat accounts, and the corresponding payment is deducted from their bank accounts to complete the transaction.

If the bids fail to meet the floor price, the OFS is deemed unsuccessful, and the shares remain with the seller.

The OFS mechanism enables companies to raise funds efficiently and helps them meet regulatory requirements, such as ensuring compliance with minimum public shareholding norms.

 

Features of Offer for Sale (OFS)

The following features collectively make OFS a flexible and efficient mechanism for shareholders to monetise their investments while ensuring fair market participation and regulatory compliance.
 

1. Ownership requirement

Only shareholders with over 10% of a company's share capital can propose an OFS. It is used when existing shares are added to the market.

2. Accessible to leading companies

OFS is available to the top 200 companies by market capitalisation.
 

3. Reserved shares

25% of shares are reserved for Insurance Corporations and Mutual Funds. No single bidder, other than these, can be awarded more than 25% of the bid amount.
 

4. Retail investor participation

At least 10% of the offering size is reserved for retail investors, who may receive a discount on the offer price.

5. Duration and notification

The OFS counter is open for one day. The company must notify stock exchanges at least two days before the OFS.

6. Comparison with FPO

Compared to Follow-On Public Offering (FPO), OFS is faster and more efficient. FPOs are open for 3 to 10 days and involve a longer process.
 

7. Hedged retail offers

All retail offer amounts in OFS are 100% hedged by cash and cash equivalent margins, ensuring a secure process.
 

8. Speedy process

Excess funds are returned the same day after 6:00 p.m. if there is non-allotment or partial allocation.
 

9. Margin offers

100% margin offers can change during OFS business hours. Zero percent margin offers can only be changed upwards.
 

10. Cancellation and rejection

Offers below the minimum price are rejected. The final assignment is subject to price discovery. In contrast, an FPO involves setting a price range, and bids are placed within that range.

 

How to apply for OFS?

Applying for an Offer for Sale (OFS) is a straightforward process that requires a demat and trading account. Here is a step-by-step guide:

  1. Eligibility for retail investors:
    Retail investors can participate in an OFS provided the total bid value does not exceed Rs. 2 lakh. If the bid value surpasses this limit, the application will not qualify under the retail investor category.
  2. Bidding process:
    • Online: Log in to your trading account and place your bid through the OFS section on the portal.
    • Offline: Contact your broker or dealer to place bids on your behalf.
  3. Bid price and quantity:
    Investors must specify the price they are willing to pay and the number of shares they want to buy. The bid price must meet or exceed the floor price set by the seller.
  4. Allocation process:
    Shares in an OFS are allocated either at a single clearing price or a multiple clearing price:
    • Single clearing price: All investors are allotted shares at a uniform price.
    • Multiple clearing price: Shares are prioritised based on bid prices. For example, if Company Y has a floor price of Rs. 180 and receives bids at Rs. 250, Rs. 220, Rs. 200, and Rs. 180, investors bidding Rs. 250 will receive allocation first, followed by those at lower prices.
  5. Cut-off price option:
    Investors who prefer not to specify a bid price can opt for the cut-off price. This allows participation without worrying about price discovery during the bidding process.

By following these steps, you can seamlessly apply for shares in an OFS and take advantage of this investment opportunity.

 

Rules and regulations in an Offer for Sale

The rules and regulations governing an Offer for Sale (OFS) of shares ensure orderly conduct and fair participation in the market. Here are the key regulations based on the provided reference and SEBI guidelines:

1. Eligibility criteria

OFS is available only to companies ranked among the Top 200 by market capitalisation in the equity market.

2. Notification requirement

The company must inform the stock exchanges at least two trading days prior to the date of the OFS.

3. Reserved portion for institutional investors

At least 25% of the shares offered through OFS must be reserved for Mutual Funds and Insurance Companies. No single bidder other than these entities can be allocated more than 25% of the shares offered.

4. Reservation for retail investors

A minimum reservation of 10% of the shares is made for retail investors, ensuring their participation in the offering.

5. Price discovery

The price of shares offered in an OFS is determined through a transparent bidding process on the stock exchange platform. Bidders specify the quantity and price at which they are willing to bid.

6. Disclosure and transparency

Promoters and companies must disclose all material information regarding the OFS, including the total number of shares offered, the floor price, and other relevant details, ensuring transparency for investors.

7. Regulatory approval

Prior approval from SEBI and compliance with stock exchange regulations are mandatory before conducting an OFS. The offer document must be filed with the exchanges for their approval.

8. Settlement and execution

The OFS is executed through the stock exchange mechanism, and settlement occurs as per the exchange's settlement cycle. All transactions must comply with SEBI regulations and guidelines.

9. Prohibition on price manipulation

Any attempt to manipulate the price of shares during the bidding process or post-OFS is strictly prohibited, ensuring market integrity.

10. Compliance

Promoters, companies, and intermediaries involved in the OFS must adhere to all applicable laws, regulations, and guidelines issued by SEBI and other regulatory authorities to protect the interests of investors and maintain market credibility.

These rules and regulations collectively aim to promote fair market practices, protect investor interests, and maintain market integrity during an Offer for Sale of shares.

 

Things you need to consider before investing in an OFS

Before participating in an OFS, investors should carefully evaluate the following aspects:

  1. Investor category awareness: Investors should identify whether they fall into the retail or institutional category. This distinction determines the total supply and potential share allocation.
  2. Financial preparedness: Assess whether you have the required funds in your trading account. For instance, Ms. Patel should ensure she has Rs. 225,000 to support her offer.
  3. Demat account necessity: Verify that you have a Demat account as OFS transactions can only be conducted through this electronic format.
  4. Order placement timing: Orders for OFS can only be placed between 9:15 am and 3:00 pm. Investors need to submit their orders within this timeframe.
  5. Order type consideration: Understand the order type limitations. Only limited orders can be placed; market orders are not allowed.
  6. Ownership limitation recognition: Acknowledge that companies are restricted from selling more than 25% of the OFS to a single offeror, excluding mutual funds.
  7. Post-investment process awareness: Recognise that successful bidders can expect shares to be credited to their Demat accounts as per the trade settlement cycle.
  8. Comparison with Institutional Investors: Be aware of the potential for institutional investors to secure a higher total supply compared to retail investors.

 

Example of OFS

  • ABC Company plans to raise funds via OFS at Rs. 100 per share.
  • Mr X, a retail investor, bids for 5,000 shares, totalling Rs. 5,00,000.
  • DEF Capital Fund, a mutual fund, bids for 10,000 shares, totalling Rs. 10,00,000.
  • Since Mr X’s total bid falls under the Rs. 2 lakh retail category cap, his allotment may be limited.
  • DEF Capital, being an institutional investor, is eligible for a larger allocation portion.
  • Institutional investors often have higher bid limits and priority in allocations.
  • OFS allocation depends on investor category and bid amounts.

 

What is the difference between an OFS and IPO/ FPO?

Understand the key differences between an Initial Public Offering, Follow-on Public Offering, and Offer for Sale in the stock market. An IPO occurs when a private company goes public by issuing new shares to investors. An FPO allows an already listed company to raise additional funds by offering more shares. In contrast, an OFS enables existing shareholders, typically promoters, to sell their stake to the public. Learning these distinctions can help investors better evaluate opportunities and make informed investment decisions.

FeatureIPO (Initial Public Offering)FPO (Follow-on Public Offering)OFS (Offer for Sale)
Listing statusUsed by unlisted companies to go public and list their shares on a stock exchange.Conducted by companies that are already listed on a stock exchange.Also applicable to companies that are already listed on a stock exchange.

What are the advantages of an OFS?

An Offer for Sale (OFS) offers several benefits for both sellers and investors, making it a popular mechanism in the stock market. These advantages include:

  • Cost-effective: OFS is a cost-effective way for promoters or existing shareholders to sell their shares in a listed company since the process does not involve the company itself. This bypasses the expenses associated with an IPO or FPO, such as underwriting fees, legal fees, and registration expenses.
  • Efficient: OFS is an efficient way for stakeholders to liquidate their holdings in a listed company and raise funds as the bidding process is carried out in a single day, and the transaction is settled within two working days.
  • Quick Execution: OFS does not require a lengthy process of filing a draft offer document, getting the document approved by SEBI, and undertaking roadshows to invite bids; hence, it helps in quick execution of the transaction.
  • Transparency: OFS is a transparent process because the bidding happens on a stock exchange platform, where all the details are visible to the public. The seller sets a floor price, which is the minimum price at which the shares can be bid for, and the bid data is available in real-time.
  • Flexible: OFS provides sellers with the flexibility to choose the number of shares they want to sell and at what price. The seller can also decide not to sell shares if the bids do not meet their expectations.
     

What is the bidding process in OFS?

In an Offer for Sale (OFS), investors must bid at or above a minimum price known as the floor price. Bids placed below this price are rejected. Shares in an OFS can be allotted using two methods:

  • Single Clearing Price: All successful bidders receive shares at one uniform price.
  • Multiple Clearing Prices: Shares are distributed starting from the highest bids.

For instance, if Rahul bids Rs. 40 and Ajay bids Rs. 30, Rahul will get preference. Investors may also choose the cut-off price option, which ensures allotment at the final determined price—provided their bid exceeds or equals it.

 

Who can invest in an OFS?

An OFS is available to both retail and institutional investors.

  • Retail investors are individuals whose total bid does not exceed Rs. 2 lakh.
  • Institutional investors include mutual funds, insurance firms, foreign portfolio investors, etc.
    The exact eligibility norms and share allocation ratios may differ across OFS events, depending on issuer guidelines and regulatory limits.

 

What are the disadvantages of an OFS?

Despite its benefits, the OFS mechanism has some limitations, which include:

  1. Limited window to participate: The window to participate in the OFS is usually limited to one trading day, unlike in Follow-on Public Offerings (FPOs) where investors get at least three days to place their bids. This provides limited opportunity for the investors to participate in the OFS and gain an advantage of the same.
     
  2. Retail investors receive a lower allocation: According to SEBI norms, retail investors must receive at least 10% of the offer, which could be as high as 20% in the case of power supplies. However, this is significantly lower than the 35% reserved for individual investors in case of initial public offerings (IPOs).
     
  3. Limited information: Unlike IPOs, where companies are required to provide detailed information about their business, OFS does not require companies to provide any such information. This can make it difficult for investors to make informed decisions.
     
  4. Market volatility: The price of shares in an OFS is determined by market demand and supply. This can lead to high volatility in the share price, which can be risky for investors.

 

Conclusion

The Offer for Sale (OFS) allows promoters to reduce their holdings in listed companies while enabling retail investors to participate in the share sale. Despite having both advantages and limitations, its key strength lies in improving public access to shares through a transparent market-based process.

Frequently asked questions

What is OFS?

Offer for Sale (OFS) is a mechanism that allows promoters, existing shareholders, or government entities to sell their shares in a listed company through the stock exchange. This method enables them to reduce their stake in the company without issuing new shares, ensuring that the existing share capital remains unchanged.

Who can invest in OFS?

All market participants, including individuals, mutual funds, foreign portfolio investors (FPIs/FIIs), insurance companies, corporates, other qualified institutional bidders (QIBs), HUFs, NRIs, etc., are eligible to bid/participate in the OFS process to acquire shares.

What is a significant drawback of OFS?

A major drawback of OFS is the lack of control the seller has over the share price. The price is determined by market forces of demand and supply, potentially resulting in a lower-than-expected selling price.

How is OFS allocation determined?

Investors can participate in OFS by submitting bids through existing Trading Members of NSE. They must provide bids specifying the quantity and price at which they wish to bid. Retail investors may also have the option to bid at the "cut-off," with the allocation being based on the cut-off price determined in the non-retail category.

Who is restricted from participating in the OFS bid?

The promoter of the company and its affiliated entities are the only entities prohibited from participating in the OFS bid.

What is the difference between IPO and OFS?

The key difference lies in the nature of shares being sold:

  • In an Initial Public Offering (IPO), a company issues new shares to raise fresh capital, often to fund expansion, operations, or other business needs.
  • In an Offer for Sale (OFS), existing shareholders, such as promoters or major stakeholders, sell their existing shares to the public. The company does not receive any fresh capital through this process.

What are the benefits of OFS?

Offer for Sale (OFS) provides liquidity to existing shareholders by allowing them to sell their shares directly to the public. It helps promoters or large investors diversify their holdings, comply with regulatory requirements on minimum public shareholding, and realise their investments efficiently through transparent market mechanisms.

Is OFS good or bad?

OFS can be beneficial as it provides liquidity and price discovery for existing shareholders, fostering market participation. However, it depends on the context and objectives of shareholders and the company. It is essential to consider factors like market conditions, regulatory compliance, and shareholder interests when evaluating whether OFS is favourable.

What is the meaning of OFS in banking?

In banking and finance, OFS (Offer for Sale) refers to a mechanism where promoters or large shareholders sell their shares through the stock exchange platform. It helps meet regulatory requirements like minimum public shareholding without issuing new shares.

What is the difference between a right issue and an offer for sale?

A rights issue allows existing shareholders to purchase additional shares in proportion to their holdings, usually at a discounted price. An offer for sale involves promoters selling their existing shares through the exchange. A rights issue raises fresh capital for the company, while OFS does not.

When can I sell OFS shares?

You can sell OFS shares after they are credited to your demat account and the shares are listed for regular trading. There is no mandatory lock-in period for retail investors in an OFS, unless specifically mentioned. Selling is subject to normal market conditions and trading rules.

Are there any charges for participating in an OFS?

Yes, investors participating in an Offer for Sale (OFS) may incur standard brokerage, Securities Transaction Tax (STT), and other statutory charges such as GST, stamp duty, and exchange transaction fees. These charges are similar to those applicable to regular equity trades and vary depending on the broker and trading platform used.

Which investor categories are eligible to participate in an OFS?

Various investor categories can participate in an OFS, including retail investors, qualified institutional buyers (QIBs), and non-institutional investors (NIIs). Retail investors typically have a separate reservation portion and can apply through their trading accounts during the OFS bidding window announced by the company and stock exchanges.

What is the discount offered in an OFS?

In many OFS issues, retail investors are offered a discount on the floor price to encourage wider participation. This discount is usually around 5%, although it can vary depending on the company and the specific offer. The discount is applied to the final discovered price during allotment.
