How to Invest in Debentures in India

Debentures are long-term debt instruments issued by corporations and governments to raise capital. Debentures represent a loan taken by the issuer for a specified period with fixed interest payments. 

When you purchase a debenture, you are essentially lending money to the issuer. In return, the issuer promises to make regular interest payments (known as coupon payments) to you for a specified period. At the end of the debenture’s term, the principal amount is repaid to you.

Debentures are generally issued in the form of certificates or bonds and are backed by the issuer’s creditworthiness.

Debenture Credit Ratings

You will receive the interest rate on debentures based on the company’s credit rating, which is measured by credit-rating agencies. These agencies measure the creditworthiness of corporate and government issues. 

These ratings help you make informed decisions by providing an independent opinion on the company’s ability to meet their financial obligations. The assigned rating indicates the level of risk associated with the debenture, with higher ratings reflecting lower perceived risk.

When assigning debenture ratings, credit rating agencies analyze various factors, including financial stability, debt levels, cash flow position, industry dynamics, and overall economic conditions. They conduct a thorough evaluation of the company’s financial statements, market position, management quality, and governance practices.

Credit rating agencies like Standard and Poor’s, use letter grades to indicate creditworthiness. The Standard & Poor’s system uses a scale that ranges from AAA for excellent rating to the lowest rating of C and D.

The higher the rating, the lower the perceived risk associated with the debentures. Ratings in the AAA to BBB range are considered investment-grade, indicating a lower risk of default. 

Ratings below the investment-grade range such as BB and below, are classified as speculative or non-investment grade, implying a higher risk profile.

Additionally, credit rating agencies such as Moody’s and FitchRatings provide their own credit rating scales for long-term debentures. These scales serve as benchmarks for assessing the creditworthiness of issuers and include:

Features Of Debentures

  • Written Promise: Debentures are written documents from the issuer to the investor. The terms and conditions of the debenture, including the interest rate, repayment schedule, and other relevant details, are clearly outlined in a formal written document. This provides legal certainty and ensures that both parties understand their rights and obligations.
  • Fixed Interest Payments: Debentures offer a fixed rate of interest, known as the coupon rate, which is predetermined at the time of issuance. You can receive regular interest payments at specified intervals throughout the debenture’s term.
  • Maturity Date: Debentures have a defined maturity date, indicating the date on which the issuer is obligated to repay the principal amount to the debenture holders. This provides clarity on the duration of the investment.
  • Priority claim: In case of liquidation or bankruptcy, you have a prior claim on the issuer’s assets compared to equity shareholders. Debenture holders are typically repaid their principal amount before equity shareholders receive any distributions. This priority claim enhances the security and potential recovery for debenture holders in adverse situations.
  • Credit Rating: Debentures are often assigned credit ratings by recognized rating agencies, reflecting the issuer’s creditworthiness. These ratings provide you with insights into the level of risk associated with the investment.

Types Of Debentures

Debentures can be classified into various types based on their characteristics and features. Let’s explore some common types:

#1. Based on Convertibility

A. Convertible Debentures:  Convertible debentures provide you with the option to convert your debentures into equity shares at a predetermined conversion ratio after a specific period. This feature provides the potential for capital appreciation and allows you to participate in the company’s growth.

Convertible debentures are of two types.

  • Fully Convertible Debentures: Fully convertible debentures can be fully converted into equity shares at the predetermined conversion ratio, allowing you to participate in the company’s growth.
  • Partly Convertible Debentures: Partly convertible debentures enable you to convert only a portion of your debentures into equity shares, while the remaining portion remains as non-convertible with fixed interest payments.

B. Non-Convertible Debentures: Non-convertible debentures cannot be converted into equity shares. These debentures provide fixed interest rates and repay the amount to you at maturity.

#2. Based on Security

A. Mortgage/Secured Debentures: Mortgage or secured debentures are issued against collateral security. This provides an added layer of security to you. In case of default, you can claim the underlying asset to recover your investment.

These types of debentures offer a lower risk to the debenture holder and, therefore, generally provide a lower rate of interest compared to unsecured debentures.

B. Unsecured Debentures: Unsecured debentures also known as unsecured bonds or debenture bonds, are not backed by any collateral. The debenture holder relies solely on the creditworthiness and reputation of the company. 

In case of default, unsecured debenture holders are considered general creditors and have a lower priority in recovering their investment compared to secured debenture holders.

#3. Based on Redemption

A. Redeemable Debentures: Redeemable debentures have a specific maturity date, upon which the issuer is obligated to repay the principal amount to the investors. Investors receive regular interest payments until maturity. 

These debentures provide a clear timeline for the return of the principal investment and are commonly issued by both corporations and governments.

B. Irredeemable Debentures: Irredeemable debentures, also known as perpetual debentures, do not have a maturity date. The redemption happens only when the issuing company is liquidating or a specific contractual provision. 

The debenture holder receives regular interest payments indefinitely, without the expectation of the principal repayment.

#4. Based on Registration

A. Registered Debentures: Registered debentures are those in which the details of all debenture holders, such as names, addresses, debenture holdings, are recorded in the company’s register. 

However, transferring registered debentures is a more complex process, as it involves complying with the provisions outlined in the Companies Act, 2013. 

B. Bearer Debentures: Bearer debentures, also known as unregistered debentures, the details of all debenture holders are not registered with the company. These debentures are freely transferable which means you can easily buy and sell them.
