What is a Debenture? Meaning, Definition & How It Works
A debenture (डिबेंचर, sometimes called ऋणपत्र in Hindi) is a long-term debt instrument that a company issues to raise funds from the public or institutional investors, without diluting ownership.
Under the Companies Act, 2013, a debenture includes debenture stock, bonds, and any other instrument of a company evidencing a debt, whether constituting a charge on assets or not.
Companies use debentures when they want to borrow without giving up equity control, and investors buy them for a predictable, fixed income stream.
In India, listed debentures are also regulated by SEBI’s debt securities framework, which governs disclosure and listing on stock exchanges. A debenture holder has no voting rights in the company; that right belongs only to shareholders.
How Does a Debenture Work?
- Issuance: the company issues debentures with a fixed face value, interest rate (coupon), and maturity date, often through a public offer or private placement.
- Interest payments: the company pays interest to debenture holders at fixed intervals, monthly, quarterly, or annually, regardless of company profit.
- Trust deed and trustee: for public issues, a debenture trustee is appointed to protect holders’ interests, as required under SEBI and Companies Act rules.
- Redemption: on maturity, the company repays the face value, unless the debenture is convertible, in which case it converts to equity shares per pre-set terms.
Pro Tip: Check the credit rating (CRISIL, ICRA, CARE) before investing in a debenture; a lower rating means higher default risk even if the coupon looks attractive.
Example: Debenture in Action
Meera, a 45-year-old teacher in Ahmedabad, invests ₹1,00,000 in a 5-year secured, non-convertible debenture (NCD) issued by an NBFC, paying 9% annual interest.
Detail | Value |
Face value invested | ₹1,00,000 |
Coupon rate | 9% per year |
Annual interest | ₹9,000 |
Tenure | 5 years |
Redemption value at maturity | ₹1,00,000 |
Meera receives ₹9,000 every year as interest and gets her ₹1,00,000 back at the end of 5 years. Because the NCD is secured, she has a charge on specific company assets if the issuer defaults.
Types of Debentures
Secured Debentures
Backed by a charge on the company’s assets, so holders can recover dues by claiming those assets if the company defaults. These typically carry a slightly lower interest rate than unsecured ones due to lower risk. See how a similar charge structure works for collateral.
Unsecured Debentures
Not backed by any specific asset; repayment depends entirely on the issuer’s creditworthiness. These carry higher interest rates to compensate investors for the added risk.
Convertible Debentures
Can be converted into equity shares of the company after a specified period, on terms fixed at issuance. Investors get fixed income initially and potential equity upside later.
Non-Convertible Debentures (NCDs)
Remain debt instruments throughout their tenure and are repaid in cash at maturity. Most retail NCDs listed on Indian exchanges fall in this category.
Redeemable vs Irredeemable Debentures
Redeemable debentures have a fixed maturity date for repayment; irredeemable (perpetual) debentures have no fixed maturity and are rare in Indian practice.
Quick Comparison
Type | Backed by Assets | Converts to Equity |
Secured NCD | Yes | No |
Unsecured NCD | No | No |
Convertible Debenture | Varies | Yes |
Key Components of a Debenture
- Face value: the amount printed on the debenture certificate, which is also the sum repaid at redemption unless issued at a discount or premium.
- Coupon rate: the fixed annual interest rate the issuer pays the holder, stated at issuance and generally unchanged through the tenure.
- Maturity date: the date on which the issuer must repay the face value to the holder, defining the debenture’s tenure.
- Debenture trust deed: the legal document, overseen by a SEBI-registered debenture trustee, that sets out the issuer’s obligations and holders’ rights.
- Credit rating: an independent assessment (CRISIL, ICRA, CARE) of the issuer’s ability to honour interest and repayment, directly affecting the debenture’s risk and pricing.
Benefits of Debentures
- Fixed, predictable income: debenture holders receive a stated interest rate regardless of the company’s profit performance, unlike dividends on shares.
- Priority over shareholders: in case of liquidation, debenture holders are repaid before equity and preference shareholders, giving them a stronger claim.
- No dilution for the company: issuing debentures lets a company raise funds without giving up ownership or voting control, useful for Indian promoters protecting their stake.
- Potential equity upside: convertible debentures let investors start with fixed income and later benefit from company growth through equity conversion.
Risks & Limitations of Debentures
- Credit/default risk: if the issuing company faces financial trouble, it may delay or default on interest and principal payments, especially for unsecured debentures.
- Interest rate risk: when market interest rates rise after issuance, existing debentures with lower coupons become less attractive and may trade below face value if sold early.
- Liquidity risk: many Indian NCDs, especially privately placed ones, have thin trading volumes, making it hard to exit before maturity without a price discount.
Important: A high coupon rate on a debenture often signals higher underlying risk, not a better deal; always check the credit rating alongside the rate.
Frequently Asked Questions
What is a debenture in simple terms?
A debenture is a certificate of debt a company issues to borrow money from investors, promising fixed interest and repayment of the principal on a set date.
Are debentures secured or unsecured?
They can be either. Secured debentures are backed by a charge on company assets; unsecured debentures rely solely on the issuer’s creditworthiness, which is why the offer document must state this clearly.
Are debentures assets or liabilities for a company?
Debentures are liabilities for the issuing company, since they represent borrowed money the company must repay with interest. For the investor holding them, they are a financial asset.
What is the typical interest rate on debentures in India?
Rates vary by issuer credit rating and tenure; secured NCDs from stable NBFCs and companies have historically ranged roughly 8-11% per year, while lower-rated or unsecured issues offer higher coupons to compensate for risk.
What are the main disadvantages of investing in debentures?
Key drawbacks include credit/default risk if the issuer struggles financially, limited liquidity for early exit, and fixed returns that do not rise even if the company performs exceptionally well.
Who are debenture holders and what rights do they have?
Debenture holders are the company’s creditors, entitled to fixed interest and repayment of principal, plus priority over shareholders in liquidation. They do not get voting rights or a share in company profits beyond the stated interest.
Should I invest in debentures for regular income?
Secured, highly-rated NCDs can suit investors seeking fixed income with a defined tenure. Check the credit rating, security cover, and liquidity before committing, and avoid concentrating too much in a single issuer.
