Debenture Bonds

Debenture bonds are corporate debt obligations backed by issuer credit rather than specific pledged collateral.

Equipment Trust Bond

An equipment trust bond is secured by transportation or industrial equipment and repaid from issuer payments tied to the asset.

Equipment Trust Certificate

An equipment trust certificate represents a secured interest in equipment financing, often used by railroads, airlines, or transport companies.

Secured Bond

A secured bond is backed by pledged collateral, giving bondholders a claim on specified assets if the issuer defaults.

Secured Loan Stock

Secured loan stock is debt backed by collateral, giving lenders asset claims that can affect recovery value and credit pricing.

Senior Secured Bonds

Senior Secured Bonds are debt instruments backed by specific collateral, offering higher security to investors and generally receiving higher credit ratings.

Unsecured Bond

An unsecured bond is not backed by specific collateral, so repayment depends primarily on the issuer's general creditworthiness.
