MUMBAI / NEW DELHI, OCTOBER 31, 2026 — As of Friday, October 30, 2026, the primary market framework governed by the Securities and Exchange Board of India (SEBI) continues to rely on the book-building mechanism to discover fair equity pricing. For retail individual investors applying via Application Supported by Blocked Amount (ASBA), selecting the cut-off option guarantees that the submitted bid automatically adjusts to whatever final price the issuer and book-running lead managers (BRLMs) establish at the close of bidding.
Key Takeaways at a Glance
- Price Band Definition: The floor and cap prices set by issuers in consultation with merchant bankers, capped at a 20% spread under SEBI ICDR regulations.
- Cut-off Price Protection: Ticking the cut-off checkbox mandates payment at the cap price during application, ensuring retail bids remain valid regardless of where the clearing price lands.
- Category Eligibility: Only Retail Individual Investors (bids up to ₹2,00,000) and eligible employees can bid at cut-off; Non-Institutional Investors (NIIs) and QIBs must bid at exact price points.
Understanding the Book-Building Process Under SEBI Framework
Under Chapter II of the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018, an initial public offering (IPO) can be conducted either as a fixed-price issue or via the book-building route. Over 98% of mainboard issues on BSE India and NSE India adopt the book-building structure. In this method, the issuer does not declare a single final price upfront. Instead, the company provides a price band—comprising a floor price (minimum) and a cap price (maximum).
SEBI mandates that the cap price cannot exceed 120% of the floor price (a maximum 20% spread). Investors evaluate the Red Herring Prospectus (RHP) and submit bids indicating how many shares (in standardized market lots) they are willing to purchase at their chosen price points. Reviewing the live IPO calendar and bidding schedule allows investors to track when the three-day bidding window opens and closes.
| Standard Bidding Milestone | Regulatory Timeline Reference |
|---|---|
| RHP Filing & Price Band Declaration | Minimum 2 Working Days Prior to Issue Open |
| Anchor Investor Bidding Window | Day T-1 (One Day Prior to Public Open) |
| Public Bidding Window (Retail, NII, QIB) | Days T to T+2 (Minimum 3 Working Days) |
| Basis of Allotment Finalisation | Day T+1 Working Day Following Close |
| Credit of Equity Shares & Mandate Unblocking | Day T+2 Working Day |
| Secondary Market Exchange Listing | Day T+3 Working Day |
What Ticking ‘Cut-off Price’ Actually Means on the Bidding Platform
When completing an ASBA application through a broker or net banking interface, retail investors encounter a checkbox marked ‘Cut-off’. Selecting this option instructs the stock exchange trading systems (NSE Syndicate or BSE iBids) that the applicant is willing to purchase the allocated shares at whatever clearing price is finalised during price discovery.
Because the final price cannot be determined until institutional and non-institutional demand is aggregated after the issue closes, the application requires the applicant to block funds corresponding to the highest possible valuation—the cap price. If institutional demand leads the issuer to price the issue below the cap, the registrar issues a partial unblock instruction to the investor’s bank for the surplus funds via the UPI or ASBA framework.
| Bidding Feature / Rule | Operational Specification |
|---|---|
| Eligible Investor Categories | Retail Individual Investors (RII) & Employees |
| Ineligible Categories | QIB, sNII (₹2L–₹10L), bNII (>₹10L) |
| Maximum Investment Threshold for Cut-off | ₹2,00,000 Total Outlay |
| Upfront Fund Blocking Requirement | 100% at Upper Cap Price |
| Refund / Unblock Handling | Automatic via ASBA Bank Mandate |
Step-by-Step Mathematical Walkthrough (Illustrative Case)
To visualize how price mechanics function during an issue, consider a purely illustrative hypothetical offering. An issuer files an offer with a defined price band and lot size:
- Illustrative Price Band: ₹100 (Floor Price) to ₹105 (Cap Price).
- Illustrative Lot Size: 100 shares per bid lot.
- Investor A (Specific Price Bid): Submits a manual bid of 1 lot (100 shares) at ₹102. Amount blocked: ₹10,200.
- Investor B (Cut-off Price Bid): Selects the ‘Cut-off’ checkbox for 1 lot (100 shares). Amount blocked upfront: ₹10,500 (100 × ₹105 Cap).
When bidding concludes, the issuer aggregates the demand book across all institutional and non-institutional categories. Two distinct scenarios can occur:
Scenario 1: Strong Demand Settles Issue at Cap (₹105)
Because subscription is strong across books tracked via the open and upcoming IPO calendar, the clearing price is determined at ₹105. Investor B’s cut-off bid matches the final price and qualifies for the allotment lottery. Investor A’s bid of ₹102 is lower than the clearing price of ₹105. Under SEBI rules, Investor A’s application is rejected immediately from the allotment pool without participating in the lottery, and their ₹10,200 block is released.
Scenario 2: Moderate Demand Settles Issue Below Cap (₹102)
If the order book clears at ₹102, Investor A qualifies for the allotment pool. Investor B also qualifies automatically because the cut-off bid adjusts downward from ₹105 to ₹102. If Investor B receives an allotment, ₹10,200 is debited from their account, and the remaining ₹300 blocked balance is unblocked by their bank upon confirmation at the IPO allotment status verification hub.
Why Non-Institutional Investors (NII / HNI) Cannot Use Cut-off
Under SEBI ICDR guidelines, the privilege of bidding at cut-off is restricted strictly to retail individual investors (applications up to ₹2,00,000) and reservations for eligible company employees. High-Net-Worth Individuals (HNIs) participating across the Small NII category (sNII, bidding between ₹2,00,000 and ₹10,00,000) and Big NII category (bNII, bidding above ₹10,00,000) cannot select cut-off.
Non-institutional applicants must specify an exact numeric price within the band. Because nearly all oversubscribed book-built issues clear at the cap price, non-institutional participants generally enter the upper cap manually. Entering a figure below the cap in an oversubscribed issue results in immediate bid disqualification when the clearing price matches the cap.
Common Bidding Pitfalls to Avoid in Primary Issues
Retail investors frequently encounter administrative rejections or missed allocations due to procedural misunderstandings. The three primary operational errors include:
- Entering the Floor Price Manually: Attempting to seek a discount by bidding at the lower end of the band. In any issue that is oversubscribed, the final price is fixed at the cap, rendering all floor bids invalid.
- Exceeding the ₹2,00,000 Retail Limit: Bidding for multiple lots that total more than ₹2,00,000 while marking the category as retail. The exchange validation engine will flag and reject the cut-off selection, reclassifying the bid into the sNII segment where cut-off pricing is disallowed.
- Delayed UPI Mandate Approval: Failing to authorize the UPI mandate on the sponsor bank app before the regulatory deadline (5:00 PM IST on issue closing day). An unconfirmed mandate prevents the bid from being considered in the basis of allotment.
What to Check Before Submitting Your IPO Bid
- Verify that the total application value (lot size × cap price) remains strictly below ₹2,00,000 if bidding in the retail category.
- Ensure the ‘Cut-off Price’ box is explicitly checked if applying as retail to avoid elimination if the clearing price settles at the cap.
- Confirm that sufficient clear balance is maintained in your bank account until the registrar finalises the basis of allotment.
- Verify that the PAN attached to the bank account and Demat account are completely identical to avoid third-party ASBA rejection.
Frequently Asked Questions
Does ticking cut-off price guarantee share allotment in an IPO?
No, ticking cut-off does not guarantee an allotment of shares. It only guarantees that your bid remains eligible for the allotment lottery if the issue is oversubscribed in the retail segment. In heavily subscribed issues, allotment is conducted via a computerized draw supervised by SEBI and exchange officials.
What happens if the final issue price is lower than the cut-off bid?
When an applicant selects cut-off, funds are initially blocked at the upper cap price. If the issuer and lead managers determine a final issue price below the cap, successful allottees are charged only the final price, and the excess blocked funds are released to the bank account via standard ASBA unblocking protocols.
Can an HNI or corporate investor bid using the cut-off option?
No, under SEBI ICDR regulations, cut-off bidding is strictly prohibited for Non-Institutional Investors (NIIs/HNIs) and Qualified Institutional Buyers (QIBs). Any non-retail participant must submit precise numerical price points within the declared price band on the exchange bidding platform.
