Debentures - Types, Returns, and Investment Risks

What are Debentures?

Debenture derives from the Latin debentur, which means "to owe." It is a firm's obligation to repay funds borrowed along with interest. A debenture is commonly kept in dematerialised form, it notes details of a loan, such as interest rates and maturity period, and it acts as an agreement. Debentures can be secured or unsecured instruments.

Types of Debentures in Funds

Debentures held in mutual fund portfolios can take multiple forms, each showing particular risk-return aspects.

• Secured Debentures: These are secured by company assets, which can be sold to repay investors in the event of issuer failure, making them relatively lower risk
• Unsecured Debentures: No collateral support leaves their value tied to the issuer's trustworthiness, sometimes bringing higher risk and increased interest payments.
• Convertible Debentures: Convertible debentures enable investors to change the debt into equity at a fixed proportion once a specific period has passed. They provide an opportunity for profits if the share price rises.
• Non-Convertible Debentures (NCDs): Non-convertible debentures offer regular interest payments and repay the original amount at maturity. They cannot convert into shares.
• Redeemable Debentures: Redeemable debentures are repaid by the issuer at or before the maturity date as per the terms stated at issuance. They help cash flow adhere to a fixed timetable.
• Irredeemable (Perpetual) Debentures: Perpetual or irredeemable debentures do not have a fixed maturity date and may continue until the issuer decides to redeem them. Traditional irredeemable debentures are uncommon in India, though certain perpetual instruments such as AT1 bonds issued by banks may have no fixed maturity.

How Debentures Generate Returns

Debentures provide several ways for investors to receive a return through a number of mechanisms:

• Interest Income: Debentures typically have regular interest (coupon) payments to investors at fixed or floating rates of interest. This interest forms the principal earnings for the debenture holders.
• Price Appreciation: If debentures are traded in the secondary market, their prices may increase due to changes in interest rates or improvements in credit quality, allowing for capital gains.
• Conversion Gains: Convertible debentures present a potential advantage if the holder changes the debt into shares and the equity price is higher than the agreed conversion price.
• Yield to Maturity: Yield to Maturity (YTM) is the total return expected if a debenture is held to maturity, assuming interest is reinvested at the same rate.

Risks Associated with Debentures

One should carefully consider the following potential risks related to debenture investments before making an investment:

• Credit Risk: Occurs when the issuer may be unable to pay interest or principal amounts and fails to meet its obligations. Higher uncertainty calls for a corresponding increase in interest.
• Interest Rate Risk: When overall interest rates rise, prices of current fixed rate debentures can fall, reducing their resale value.
• Liquidity Risk: Some debentures may be hard to sell before maturity, possibly requiring a lower price.
• Inflation Risk: Rising inflation can reduce the real value of fixed interest payments.
• Business and Market Risk: Economic or business problems may impact a company's ability to repay debts, which will impact returns.
• Regulatory & Tax Risk: Changes in regulations or tax laws affecting activities would impact post-tax returns and debenture valuation.

Debenture Role in Portfolio Diversification

Debentures can play an important role in improving the stability of the portfolio and risk management through several different mechanisms:

• Fixed-Income Component: Debentures offer predictable interest income, balancing riskier equity investments.
• Risk Diversification: A collection of debentures with different credit ratings and maturities spreads risk across the issuers and changes in interest rates.
• Steady Cash Flow: Regular interest payments provide investors with steady funds.
• Lower Correlation: Debentures tend to move differently from equities and thus can help to lower portfolio volatility.
• Credit Exposure Management: The diversification away from equities or bank deposits can be achieved by the selection of debentures across credit ratings.
• Liquidity: Some listed debentures are liquid, allowing for efficient portfolio adjustments.
