A Zero Coupon CCD lets an Indian startup raise bridge capital without paying any interest, in exchange for handing the investor more equity when the debenture converts. It has become one of the most-used instruments for pre-Series A and bridge rounds in India’s tighter 2026 funding market, where preserving cash matters more than ever. The trade-off is real: you save cash today but accept heavier dilution tomorrow.
This guide breaks down exactly how a zero-coupon CCD works, its five biggest benefits, its five most serious drawbacks, and the India-specific compliance rules under the Companies Act 2013, FEMA, and Ind AS 109 that every founder must get right before signing a term sheet.

- A Zero Coupon CCD is a compulsorily convertible debenture issued with a token interest rate, usually 0.001%, that mandatorily converts into equity at a pre-agreed discount instead of paying cash interest.
- Zero coupon CCDs preserve startup runway by eliminating periodic interest outflows, making them ideal for bridge rounds of roughly ₹50 lakh to ₹3 crore, six to twelve months before a priced round.
- The core trade-off is dilution: investors typically receive 15% to 25% more shares at conversion to compensate for the interest they forgo.
- Under Section 71 of the Companies Act 2013, a debenture cannot carry a literal zero rate, so a nominal 0.001% coupon is used to keep the instrument legally valid.
- For any foreign investor, FEMA Non-Debt Instrument Rules require the conversion price to be fixed upfront and to never fall below the fair market value certified at issuance by a registered valuer or merchant banker.
- Under Ind AS 109, even a zero coupon CCD is a compound financial instrument that must be split into a debt component and an equity conversion component, which invites audit scrutiny.
- My Valuation is an IBBI-registered valuation firm that certifies fair market value for CCD issuance, structures conversion terms, and ensures FEMA and Ind AS compliance for Indian startups.
What Is a Zero Coupon CCD?
A Zero Coupon CCD is a compulsorily convertible debenture that pays no meaningful interest during its life and instead compensates the investor with additional equity at conversion. In practice it carries a nominal rate of 0.001% to 0.01%, because Indian company law does not permit a debenture with a literal zero rate.
A standard CCD (compulsorily convertible debenture) is a hybrid instrument. It behaves as debt on your balance sheet until a fixed date or trigger event, then mandatorily converts into equity shares. There is no cash repayment of principal. A zero coupon CCD is simply a CCD where the interest component has been engineered down to near-nothing.
The investor is not doing this for free. In return for waiving interest, they receive a conversion discount, typically 15% to 25%, meaning they buy shares at conversion cheaper than the incoming priced-round investors. That discount is how they earn their return.
This structure suits founders who cannot yet agree on a valuation and cannot afford interest payments. It is why zero coupon CCDs have become a go-to bridge instrument for Indian startups moving between rounds in 2026.
How Does a Zero Coupon CCD Actually Work?
A zero coupon CCD works in three stages: issuance as debt, a dormant holding period with no cash interest, and mandatory conversion into equity at a discounted price.
Stage 1: Issuance. The company issues the CCD at face value, sets a nominal 0.001% coupon, fixes the tenure (usually one to three years, capped at ten), and defines the conversion mechanics, either a discount to the next round, a valuation cap, or both.
Stage 2: Holding period. The CCD sits as a borrowing on the balance sheet. No cash leaves the company. This is the entire point of the instrument.
Stage 3: Conversion. On the trigger event, usually the next priced round, the CCD converts using this formula:
Shares Allotted = (CCD Face Value + Accrued Interest) ÷ Conversion Price per Share
Because accrued interest is negligible, the number of shares is driven almost entirely by the conversion price, which is set below the round price via the discount or cap.
A Worked Example in INR
Assume a startup raises ₹2 crore via a zero coupon CCD with a 20% conversion discount, then closes a Series A twelve months later at a share price of ₹100.
- The CCD holder converts at ₹100 minus 20%, so ₹80 per share.
- Shares allotted = ₹2,00,00,000 ÷ ₹80 = 2,50,000 shares.
- A new Series A investor putting in the same ₹2 crore at ₹100 gets only 2,00,000 shares.
- The CCD investor therefore receives 50,000 extra shares for the identical cheque, which is exactly the dilution cost the founder absorbs.
That 25% share uplift is the price of preserving cash. Whether it is worth it depends on how confident you are that your next round will be up, not down.
What Are the Benefits of Zero Coupon CCDs for Startups?
The main benefit of a zero coupon CCD is cash flow preservation, since eliminating interest payments extends runway during a startup’s most fragile phase. There are five distinct advantages worth understanding.
1. Cash Flow Preservation
A ₹2 crore CCD at a traditional 12% coupon costs ₹24 lakh in annual interest, often unaffordable for a pre-revenue company. A zero coupon structure reduces that to a few thousand rupees, freeing capital for engineering, customer acquisition, and working capital, and typically extending runway by three to six months.
2. Deferred and Predictable Dilution
The CCD does not sit on your cap table as equity until conversion. This keeps ownership percentages clean for ESOP pool planning and board decisions. Because the discount is fixed upfront, founders know in advance roughly how much dilution to expect.
3. Faster Closing and Simpler Documentation
With no interest accrual schedules or yield curves to negotiate, zero coupon CCDs close faster, often in two to three weeks rather than four to six. Term sheets are shorter, accounting entries are simpler, and legal costs are usually lower than for CCPS.
4. Founder-Friendly Bridge Terms
Zero coupon CCDs let founders raise without fixing a valuation, avoid immediate board seats or heavy protective provisions, and let existing investors bridge the company easily. Conversion triggers can be tied to specific milestones the founder controls.
5. Clean Tax Treatment During Early Stages
With effectively no interest expense, there is nothing to deduct under Section 36(1)(iii) and no TDS obligation under Section 194A of the Income Tax Act 1961. For a loss-making early-stage company that could not use the deduction anyway, this removes a compliance burden rather than sacrificing a benefit.
What Are the Drawbacks and Risks of Zero Coupon CCDs?
The main drawback of a zero coupon CCD is higher equity dilution at conversion, because the discount that replaces interest transfers more ownership to the investor. Five risks deserve careful attention.
1. Higher Dilution at Conversion
As the worked example showed, a 20% discount can hand investors 25% more shares per rupee. Across multiple bridge tranches, this can add three to five percentage points of extra founder dilution by the time Series B closes.
2. Limited Investor Appetite
Not every investor accepts a zero coupon structure. Institutional VCs often want participation rights, debt funds mandate minimum interest of 8% to 12% for their own economics, and some risk-averse angels prefer periodic income. Zero coupon CCDs work best with sophisticated angels, existing investors bridging the company, and strategic investors focused on equity upside.
3. Valuation Cap Complexity
A valuation cap protects the investor but can create friction. If you set a ₹40 crore cap and later raise Series A at ₹120 crore, the CCD holder converts at the ₹40 crore level and receives roughly 3x more shares per rupee than the new investor. This disparity can frustrate incoming investors and complicate future cap table talks. Set caps at realistic 1.5x to 2x projections, not aspirational multiples.
4. Accounting and Audit Scrutiny Under Ind AS 109
Under Ind AS 109, a CCD is a compound financial instrument. Even with a zero coupon, the conversion option must be valued separately from the debt host, usually via a Black-Scholes or binomial model, and bifurcated in the books. Zero-interest debentures also draw statutory auditor attention, especially when issued to related parties, because auditors test whether the transaction is genuinely at arm’s length.
5. Investor-Side Risks
For the investor, a zero coupon CCD carries no downside protection: if the startup fails before conversion, they are unsecured creditors recovering only the debt face value. Locked capital also loses purchasing power to inflation, and the structure is an all-or-nothing bet on equity upside compared with a traditional CCD’s guaranteed 12% return.
Zero Coupon CCD vs Traditional CCD: Which Should Founders Choose?
The choice comes down to a single trade-off: pay interest in cash now, or pay it in equity later. The table below compares both structures across the factors that matter most to a founder.
| Factor | Zero Coupon CCD | Traditional CCD | Best For |
| Interest rate | ~0.001% (nominal) | 8% to 15% annually | Zero coupon for cash-strapped startups |
| Cash outflow during tenure | Effectively nil | High (₹24 lakh/year on ₹2 cr at 12%) | Zero coupon for runway preservation |
| Dilution at conversion | Higher (15% to 25% via discount) | Lower (interest paid in cash) | Traditional CCD to protect equity |
| Closing speed | Faster (2 to 3 weeks) | Slower (4 to 6 weeks) | Zero coupon for urgent bridges |
| Investor appetite | Narrower (angels, insiders) | Broader (incl. debt funds) | Traditional CCD for institutional rounds |
| Ind AS 109 treatment | Compound instrument, bifurcation needed | Compound instrument, bifurcation needed | Neither is simpler; both need a valuer |
| Ideal use case | Bridge round, uncertain valuation | Priced debt tranche, cash-generating business | Match to your cash position |
One-line takeaway: Choose a zero coupon CCD when preserving cash outweighs the dilution cost, and a traditional CCD when your business can service interest and you want to protect founder equity.

Zero coupon CCDs must comply simultaneously with the Companies Act 2013, FEMA, and the Income Tax Act 1961, because each regulator treats the instrument differently. Getting one right and another wrong is the most common structuring mistake founders make.
Companies Act 2013
As per Section 71 of the Companies Act 2013, a debenture must carry some interest, which is why a literal zero rate is not permitted and a nominal 0.001% coupon is used. Issuing a CCD requires authorization in the Articles, a shareholder special resolution, and private placement compliance including Form PAS-4, Form PAS-5, and Form MGT-14. Because a fully and compulsorily convertible debenture must convert within ten years, it is exempt from maintaining a Debenture Redemption Reserve.
FEMA and FDI
Under the FEMA Non-Debt Instrument Rules 2019, CCDs are treated as capital instruments, equivalent to equity, from day one. If any investor is a non-resident, the conversion price or formula must be fixed upfront and, critically, the price at conversion must never fall below the fair market value certified at issuance. This is where founders slip: a steep discount that pushes the effective conversion price below issuance FMV can breach FEMA pricing norms. A registered valuer or SEBI-registered merchant banker must certify that FMV, and Form FC-GPR must be filed within 30 days of allotment via the RBI FIRMS portal.
Income Tax Act 1961
Even with a token coupon, a deeply discounted debenture can raise original-issue-discount questions, and the treatment of surplus on redemption or conversion, whether interest or capital gains, has been litigated in India. This makes documentation of the conversion mechanics essential.
As per the FEMA pricing framework, the conversion price cannot be lower than the fair market value at issuance, so the “discount” for foreign investors must be built into the issuance valuation itself, not applied later.
Conclusion: Is a Zero Coupon CCD Right for Your Startup?
A zero coupon CCD is a powerful bridge instrument when preserving cash matters more than minimizing dilution, and it fits best for startups six to twelve months from a larger round with an uncertain valuation. The catch is that the interest you save is repaid in equity, so the decision hinges on how confident you are in an up round and how carefully your conversion terms are structured.

Frequently Asked Questions (FAQs)
1. What is a zero coupon CCD in simple terms?
A zero coupon CCD is a convertible debenture that pays almost no interest and instead gives the investor extra equity when it converts. It lets startups raise cash without periodic interest payments.
2. Is a zero coupon CCD really interest-free?
Not legally. Under Section 71 of the Companies Act 2013, a debenture must carry some interest, so a nominal rate of about 0.001% is used to keep the instrument valid while keeping cash outflow near zero.
3. Do I need a valuation report for a zero coupon CCD?
Yes, if the conversion price is predetermined or any foreign investor is involved. A registered valuer or merchant banker must certify fair market value upfront, and under FEMA the conversion price cannot fall below that value.
4. How much dilution does a zero coupon CCD cause?
Investors typically receive 15% to 25% more shares at conversion to compensate for waived interest. Across several bridge tranches this can add three to five percentage points of extra founder dilution by Series B.
5. Who should use a zero coupon CCD?
Cash-strapped, pre-revenue or low-margin startups raising a bridge round of roughly ₹50 lakh to ₹3 crore, six to twelve months before a priced round, are the best fit, especially when raising from existing investors or sophisticated angels.
6. How is a zero coupon CCD treated under Ind AS 109?
It is a compound financial instrument. Even with a zero coupon, the conversion option must be valued separately from the debt component and bifurcated in the accounts, which usually requires a Black-Scholes or binomial valuation.
7. Can foreign investors subscribe to zero coupon CCDs?
Yes. CCDs are capital instruments under the FEMA Non-Debt Instrument Rules 2019, but the conversion price must be fixed upfront at or above issuance fair market value, and Form FC-GPR must be filed within 30 days via the RBI FIRMS portal.
