What are convertible debentures?

A convertible debenture is a hybrid financial instrument issued by a corporation or government entity. Initially, it functions as a regular bond, paying periodic interest to bondholders. 

However, what sets it apart is its convertibility feature. At a predetermined time or under specific conditions, the holder has the option to convert the debenture into a predetermined number of the issuing company’s common shares. 

Conversion of debentures into equity shares refers to the process where holders of convertible debentures can exchange their debt securities for a predetermined number of company shares. 

This conversion offers investors the chance to engage in potential stock value increases, rendering convertible debentures an appealing choice for individuals aiming to combine a steady income stream with the prospect of capital growth.

Convertible debentures example

Let’s consider your own convertible debentures worth ₹ 500,000, carrying an annual interest rate of 4%. These debentures provide the opportunity for conversion into equity upon maturity at a 1:10 ratio. In simpler terms, for every debenture with a denomination of ₹ 5,000, you can exchange it for 10 equity shares.

It’s crucial to understand that the conversion ratio is determined by the issuer during the initial debenture issuance. As a holder, you retain the right to either convert the debenture into equity or hold it until maturity without converting.

Debentures are considered convertible unless mentioned otherwise, and below is the list showcasing some of them currently listed on NSE.

Indian Railway Finance Corporation Ltd., Navi Finserv Ltd., IIFL Home Finance Ltd., National Highways Authority of India and Power Finance Corporation Ltd. have listed their debentures for public issue.

Types of convertible debentures

  1. Optionally convertible debentures (OCDs):

Optionally convertible debentures, as the name suggests, provide the investor with the choice to convert the debenture into equity shares or retain it as a regular debt instrument.

Investors benefit from the flexibility to assess market conditions and the issuer’s performance before deciding to convert. 

This can be advantageous when uncertainty exists regarding the company’s future prospects. Companies issue OCDs to attract capital with the promise of potential equity participation. They offer lower interest rates compared to non-convertible debentures.

  1. Fully convertible debentures (FCDs):

Fully convertible debentures are financial instruments where conversion into equity shares is obligatory within a specified timeframe, generally at a predetermined conversion ratio. Investors of FCDs do not have the option to retain them as debt. 

The conversion is mandatory when the conditions outlined in the debenture agreement are met. FCDs are popular among companies looking to raise funds for growth and expansion, as they provide a clear path to transitioning investors into equity stakeholders.

  1. Partially convertible debentures (PCDs):

Partially convertible debentures have a unique structure where only a portion of the debenture is convertible into equity shares while the remaining portion remains as debt. Investors have the choice to convert a specified percentage of their PCD holdings into equity shares, often at predetermined conversion prices. 

PCDs offer a balance between fixed-income stability and equity participation, appealing to investors seeking income while maintaining some exposure to potential capital gains.
