> A debenture is unsecured debt issued by corporations or governments that relies on the issuer's creditworthiness and reputation rather than collateral to support its value.

## What Is a Debenture?

A debenture is a type of bond or other debt instrument that is unsecured by [collateral](https://www.investopedia.com/terms/c/collateral.asp) and relies entirely on the creditworthiness and reputation of the issuer for support. Both corporations and governments frequently issue debentures to raise capital or funds, often for longer terms.

Debentures can offer regular interest payments but also carry credit risk, depending on the issuer's financial strength. Some debentures come with conversion options, such as convertible and nonconvertible types, which will be explored further.

### Key Takeaways

*   Debentures are unsecured debt instruments used by corporations and governments to raise capital; they rely solely on the issuer's creditworthiness instead of being backed by collateral.
*   There are different types of debentures, including convertible and nonconvertible as well as registered and bearer, each with unique features regarding tradability and conversion options to equity.
*   Debenture holders face risks such as interest rate risk, inflation risk, and credit risk, which are crucial to consider when assessing potential returns versus inherent risks.
*   In instances of bankruptcy, debenture holders are prioritized over common stock shareholders for repayment, giving them an edge in recovering investments compared to equity investors.

## How Do Debentures Work?

Similar to most bonds, debentures may pay periodic interest payments called coupon payments. Like other types of bonds, debentures are documented in an [indenture](https://www.investopedia.com/terms/i/indenture.asp). An indenture is a legal and binding contract between bond issuers and [bondholders](https://www.investopedia.com/terms/b/bondholder.asp).

The contract specifies features of a debt offering, such as the [maturity date](https://www.investopedia.com/terms/m/maturitydate.asp), the timing of interest or coupon payments, the method of interest calculation, and other features. Corporations and governments can issue debentures.

Governments typically issue long-term bonds—those with maturities of longer than 10 years. Considered low-risk investments, these government bonds have the backing of the government issuer.

Corporations also use debentures as long-term loans. However, the debentures of corporations are unsecured. Instead, they have the backing of only the financial viability and creditworthiness of the underlying company.

These debt instruments pay an interest rate and are redeemable or repayable on a fixed date. A company typically makes these scheduled debt interest payments before they pay stock dividends to shareholders.

Debentures are advantageous for companies since they carry lower interest rates and longer repayment dates as compared to other types of loans and debt instruments.

## Different Types of Debentures Explained

### Registered vs. Bearer

Some debentures are registered with the issuer. In this case, the transfer or trading in these securities must be organized through a clearing facility that alerts the issuer to changes in ownership so that they can pay interest to the correct bondholder.

A [bearer debenture](https://www.investopedia.com/terms/b/bearer-instrument.asp), in contrast, is not registered with the issuer. The owner (bearer) of the debenture is entitled to interest simply by holding the bond.

### Redeemable vs. Irredeemable

Redeemable debentures have specific terms and a date for full repayment. Irredeemable (non-redeemable) debentures, on the other hand, do not hold the issuer liable to repay in full by a certain date. Because of this, irredeemable debentures are also known as perpetual debentures.  

### Convertible vs. Nonconvertible

[Convertible debentures](https://www.investopedia.com/terms/c/convertibledebenture.asp) are bonds that can convert into equity shares of the issuing corporation after a specific period. Convertible debentures are hybrid financial products with the benefits of both debt and equity.

Debentures serve as fixed-rate loans with fixed interest payments. However, the holders of the debenture have the option of holding the loan until maturity and receiving the interest payments or converting the loan into equity shares.

Convertible debentures are attractive to investors who want to convert to equity if they believe the company's stock will rise in the long term. However, the ability to convert to equity comes at a price since convertible debentures pay a lower interest rate [compared to other fixed-rate](https://www.investopedia.com/ask/answers/09/non-convertible-debentures-fixed-deposits-difference.asp) investments.

Nonconvertible debentures are traditional debentures that cannot be converted into equity of the issuing corporation. To compensate for the lack of convertibility investors are rewarded with a higher interest rate when compared to convertible debentures.

## Key Features of Debentures

When issuing a debenture, first a trust indenture must be drafted. The first trust is an agreement between the issuing corporation and the trustee that manages the interest of the investors.

### Interest Rate

The coupon rate is the interest the company pays to the debenture holder. This coupon rate can be either fixed or floating. A floating rate might be tied to a benchmark such as the yield of the 10-year Treasury bond and will change as the benchmark changes.

### Credit Rating

The company's [credit rating](https://www.investopedia.com/terms/c/creditrating.asp) and ultimately the debenture's credit rating impacts the interest rate that investors will receive. Credit-rating agencies measure the creditworthiness of corporate and government issues. These entities provide investors with an overview of the risks involved in investing in debt.

Credit rating agencies, such as Standard and Poor's, typically assign letter grades indicating the underlying creditworthiness. The Standard & Poor’s system uses a scale that ranges from AAA for excellent rating to the lowest rating of C and D. Any debt instrument receiving a rating of BB and lower is said to be of speculative grade.

You may also hear these called junk bonds. It boils down to the underlying issuer being more likely to default on the debt.

### Maturity Date

For nonconvertible debentures, mentioned above, the date of maturity is also an important feature. This date dictates when the company must pay back the debenture holders. The company has options on the form the repayment will take.

Most often, it is as redemption from the capital, where the issuer pays a lump sum amount on the maturity of the debt. Alternatively, the payment may use a redemption reserve, where the company pays specific amounts each year until full repayment at the date of maturity.

## Pros and Cons of Investing in Debentures

Debentures are the most common form of long-term [debt instruments issued by corporations](https://www.investopedia.com/ask/answers/011215/how-debenture-stock-different-regular-debenture.asp). A company will issue these to raise capital for its growth and operations, and investors can enjoy regular interest payments that are relatively safer investments than a company's equity shares of stock.

Debentures are unsecured bonds issued by corporations to raise debt capital. Because they are not backed by any form of collateral, they are inherently more risky than an otherwise identical note that is secured.

Due to higher risk, debentures offer a higher interest rate to compensate bondholders. This also means that bond investors should pay careful attention to the creditworthiness of debenture issuers.

The relative lack of security does not necessarily mean that a debenture is riskier than any other bond. Strictly speaking, a U.S. Treasury bond and a U.S. Treasury bill are both debentures. They are not secured by collateral, yet they are considered risk-free.

Pros

*   A debenture pays a regular interest rate or coupon rate return to investors.
    
*   Convertible debentures can be converted to equity shares after a specified period, making them more appealing to investors.
    
*   In the event of a corporation's bankruptcy, the debenture is paid before common stock shareholders.
    

Cons

*   Fixed-rate debentures may have interest rate risk exposure in environments where the market interest rate is rising.
    
*   Creditworthiness is important when considering the chance of default risk from the underlying issuer's financial viability.
    
*   Debentures may have inflationary risk if the coupon paid does not keep up with the rate of inflation.
    

## Potential Risks of Debentures for Investors

Debenture holders may face [inflationary risk](https://www.investopedia.com/terms/i/inflationrisk.asp). Here, the risk is that the debt's interest rate paid may not keep up with the rate of inflation. Inflation measures economy-based price increases. As an example, say inflation causes prices to increase by 3%. Should the debenture coupon pay at 2%, the holders may see a net loss, in real terms.

Debentures also carry [interest rate risk](https://www.investopedia.com/terms/i/interestraterisk.asp). In this risk scenario, investors hold fixed-rate debts during times of rising market interest rates. These investors may find their debt returning less than what is available from other investments paying the current, higher, market rate. If this happens, the debenture holder earns a lower yield in comparison.

Additionally, debentures carry credit and [default risk](https://www.investopedia.com/terms/d/defaultrisk.asp). As stated earlier, debentures are only as secure as the underlying issuer's financial strength.

If the company struggles financially due to internal or macroeconomic factors, investors are at risk of default on the debenture. As some consolation, a debenture holder would be repaid before common stock shareholders in the event of bankruptcy.

## Real-World Examples of Debentures

A government debenture example is the U.S. [Treasury bond](https://www.investopedia.com/terms/t/treasurybond.asp) (T-bond). T-bonds help finance projects and fund day-to-day governmental operations. The U.S. Treasury Department issues these bonds during auctions held throughout the year.

Some Treasury bonds trade in the secondary market. In the secondary market through a financial institution or broker, investors can buy and sell previously issued bonds. T-bonds are nearly risk-free since they're backed by the full faith and credit of the U.S. government. However, they also face the risk of inflation and interest rates increase.

## How Is a Debenture Different From a Bond?

A debenture is a type of bond. In particular, it is an unsecured or non-collateralized debt issued by a firm or other entity and usually refers to such bonds with longer maturities. [Secured](https://www.investopedia.com/terms/s/securedbond.asp) bonds are backed by some sort of collateral in the form of property, securities, or other assets that can be seized to repay creditors in the event of a default. [Unsecured debentures](https://www.investopedia.com/terms/u/unsecured-note.asp) have no such collateralization, making them relatively riskier.

## Are Debentures Risky Investments?

Because debentures are debt securities, they tend to be less risky than investing in the same company's common stock or preferred shares. Debenture holders would also be considered more senior and take priority over those other types of investments in the case of bankruptcy.  

Because these debts are not backed by any collateral, however, they are inherently riskier than secured debts. Therefore, these may carry relatively higher interest rates than otherwise similar bonds from the same issuer that are backed by collateral.

In fact, strictly speaking, a U.S. Treasury bond and a U.S. Treasury bill are both debentures. They are not secured by collateral, yet they are considered risk-free securities.

## How Are Debentures Structured?

All debentures follow a standard structuring process and have common features. First, a trust indenture is drafted, which is an agreement between the issuing entity and the entity that manages the interests of the bondholders.

Next, the coupon rate is decided, which is the rate of interest that the company will pay the debenture holder or investor. This rate can be either fixed or floating and depends on the company's credit rating or the bond's credit rating. Debentures may also be either convertible or non-convertible into common stock.

## Is a Debenture an Asset or a Liability?

This depends on whose perspective is considered. As a debt instrument, a debenture is a liability for the issuer, who is essentially borrowing money via issuing these securities. For an investor (bondholder), owning a debenture is an asset.

## The Bottom Line

Debentures are unsecured debt instruments issued by corporations and governments that rely solely on the issuer's creditworthiness rather than collateral. They often offer higher interest rates than secured bonds to compensate for added credit risk, but still provide bondholders priority over equity holders in bankruptcy.

Many debentures feature fixed or floating rates, varying maturities, and even convertibility into equity. U.S. Treasury bonds, though considered risk-free due to the government's strong credit, are technically debentures because they're unsecured. Despite the risks, debentures remain attractive for their steady coupon payments and advantages over equity during liquidity challenges.
