Debt Security
A debt security is a tradable borrowing instrument that gives investors contractual claims to interest, principal, or both.
Separate debt and fixed-income classification, governing indentures, and held-to-maturity accounting treatment.
A debt security is a transferable or investable claim requiring an issuer to make specified payments, while fixed income is a broader market description that can include changing or conditional payment structures. An indenture is a governing legal contract for a debt issue. Held to maturity (HTM) is an accounting classification, not a security type or a promise that the holder cannot sell.
These labels answer different questions. The Debt Security guide addresses the claim. Fixed-Income Security explains the broader market category. Bond Indenture covers payment terms, covenants, collateral, default provisions, amendments, and trustee duties. Held-to-Maturity Securities covers accounting classification and measurement.
| Layer | Question | Evidence |
|---|---|---|
| Instrument | What claim does the holder own? | Security terms, prospectus, and confirmation |
| Contract | What must the issuer do, and what can holders enforce? | Indenture, supplemental indentures, guarantees, and security documents |
| Accounting | How does the reporting entity classify and measure the holding? | Applicable accounting standards, policy elections, intent, and ability |
| Market | What price and yield are currently available? | Executable quotes, transactions, curve, spread, liquidity, and issuer information |
A company can hold the same bond that another investor holds while reporting it differently because the companies have different accounting business models or classifications. The bond’s indenture and issuer payment obligations do not change merely because one holder uses an HTM category. Conversely, an HTM label does not repair weak credit or prevent impairment.
Confirm issuer, principal, coupon formula, maturity, priority, collateral, guarantees, covenants, call and put rights, amendment thresholds, and events of default. Then analyze accounting classification, credit quality, price, yield, duration, liquidity, and tax treatment separately.
Do not infer legal rights from an accounting label or investment safety from the phrase fixed income. This section provides general financial education, not individualized investment, legal, tax, or accounting advice.
Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.
A debt security is a tradable borrowing instrument that gives investors contractual claims to interest, principal, or both.
A fixed-income security provides scheduled interest, coupon, or principal payments under defined contractual terms.
Held-to-maturity securities are debt investments a company intends and is able to hold until maturity.
