A share represents part-ownership in a company, making the holder a member with a stake in its profits and, usually, voting rights. A debenture is a loan to the company, making the holder a creditor who is owed a fixed rate of interest and repayment of principal. In short: a share is ownership capital, while a debenture is borrowed money.
What is a share?
A share is a unit of a company’s ownership capital. When you buy equity shares, you become a part-owner, or shareholder, of that company. Your stake entitles you to a proportion of the company’s profits, usually paid out as dividends, and typically gives you voting rights at general meetings on matters such as electing directors.
Returns on shares are not guaranteed. Dividends depend on the company making profits and deciding to distribute them, and the market price of a share can rise or fall. Shareholders carry residual risk — in a winding-up, they are paid only after all creditors, including debenture holders, have been settled. In exchange for this higher risk, shares offer the potential for capital growth and a direct share in the company’s success.
Ownership also brings a say in how the company is run. Equity shareholders can vote on key decisions, receive the company’s annual reports, and benefit if the business grows in value over time. This bundle of rights — profit, control and capital appreciation — is what distinguishes a shareholder from a mere lender, and it is the reason shares are described as risk capital.
What is a debenture?
A debenture is a debt instrument through which a company borrows money from the public or investors for a fixed term. Under Section 2(30) of the Companies Act, 2013, the term “debenture” includes debenture stock, bonds and any other instrument of a company evidencing a debt, whether or not it creates a charge on the company’s assets.
When you buy a debenture, you are lending to the company, not owning part of it. In return, you are usually entitled to interest at a fixed rate, paid at regular intervals, and to repayment of the principal on maturity. Debenture holders are creditors, not members: they generally have no voting rights, but their claim ranks ahead of shareholders if the company is wound up. Debentures can be secured (backed by company assets) or unsecured, and some are convertible into shares at a later date.
The interest a company pays on debentures is a contractual obligation that must be met whether or not the business makes a profit in a given year, unlike a dividend on shares, which is paid only when the company has profits and chooses to distribute them. This fixed, prior claim is precisely what makes a debenture a lower-risk, lower-reward instrument compared with an equity share in the same company.
Shares vs debentures — the key differences
| Feature | Shares | Debentures |
|---|---|---|
| Nature | Ownership capital | Borrowed money (debt) |
| Holder’s status | Member / owner | Creditor / lender |
| Return | Dividend (not guaranteed) | Interest at a fixed rate |
| Voting rights | Usually yes | Usually no |
| Priority on winding-up | Paid last, after creditors | Paid before shareholders |
| Risk to holder | Higher — residual risk | Lower — fixed claim |
| Security | Not applicable | May be secured or unsecured |
What does the Companies Act, 2013 say?
Indian company law treats the two instruments distinctly. Section 44 of the Companies Act, 2013 provides that the shares or debentures or other interest of any member in a company are movable property, transferable in the manner laid down by the company’s articles. Section 2(30) defines a debenture, and the issue of debentures is governed by the Act read with the Companies (Share Capital and Debentures) Rules, 2014.
Where debentures are listed and offered to the public, additional SEBI regulations apply, including disclosure and investor-protection requirements. This framework exists to ensure that both owners (shareholders) and lenders (debenture holders) understand their rights and the risks they are taking on.
Which is riskier — and which suits whom?
Shares generally carry higher risk and higher potential reward. Their value can swing with company performance and market sentiment, and returns are not assured — but successful companies can deliver substantial capital gains and rising dividends over time. Debentures are typically lower risk: they offer a predictable, fixed income and rank ahead of shares for repayment, though their returns are capped at the agreed interest rate and they carry credit risk if the issuer struggles to pay.
In broad terms, shares tend to suit investors seeking growth and willing to accept volatility, while debentures suit those prioritising steadier income and capital preservation. Many portfolios hold a mix of both to balance growth and stability.
It is important to remember that debentures are not risk-free. Their safety depends on the financial strength of the issuing company: if the issuer runs into trouble, even a fixed interest payment or the return of principal can be delayed or, in the worst case, not paid in full. Credit ratings assigned by agencies help investors gauge this risk, and secured debentures offer more protection than unsecured ones because they are backed by a charge on assets.
What are the main types of shares and debentures?
Neither instrument is a single, uniform product. Shares in India fall broadly into two categories. Equity shares carry ownership, voting rights and variable dividends, and bear the greatest risk and reward. Preference shares rank ahead of equity shares for dividends and for repayment of capital in a winding-up, usually carry a fixed dividend rate, but typically come with limited or no voting rights.
Debentures are equally varied. They may be secured (backed by a charge on company assets) or unsecured; convertible or non-convertible; and redeemable at a fixed maturity or, more rarely, irredeemable. Each combination changes the balance of risk and return, which is why the offer document for any debenture issue sets out its precise terms.
How are shares and debentures issued?
Companies raise money by issuing either instrument, but the route differs. Shares are commonly issued through an initial public offering (IPO), a follow-on offering, a rights issue to existing shareholders, or a private placement. Debentures are issued to raise borrowed funds, either through a public issue or a private placement, and listed debentures must follow SEBI’s disclosure and listing rules.
In both cases, the Companies Act, 2013 and the accompanying rules govern how the securities are created, allotted and transferred, while SEBI oversees public issues and listed securities to protect investors. Once issued, both shares and listed debentures can usually be bought and sold on stock exchanges, giving investors a way to exit before a company’s winding-up or a debenture’s maturity.
Can debentures become shares?
Yes — some debentures are issued as convertible debentures, which can be converted into equity shares of the company after a set period or on specified terms. Fully convertible debentures turn entirely into shares, while partly convertible debentures convert only in part, with the remainder continuing as debt. Non-convertible debentures (NCDs), by contrast, remain debt throughout and are simply repaid at maturity. The terms of conversion, if any, are fixed at the time of issue and set out in the offer documents, so an investor knows in advance whether and how a debenture may become equity.
