A corporate bond is company-issued debt whose value depends on promised cash flows, seniority, covenants, credit quality, rates, and liquidity.
A corporate bond is a debt security issued by a company. The issuer promises to make the payments specified in the bond documents, which commonly include periodic interest and principal at maturity. Unlike a shareholder, a bondholder is a creditor: the investor has contractual payment rights but generally does not receive ownership or voting rights merely by holding the bond.
Corporate bonds vary widely. They can be fixed- or floating-rate, secured or unsecured, senior or subordinated, callable or noncallable, investment grade or high yield, and issued in different currencies and denominations.
The simplest fixed-rate bond exchanges cash as follows:

This diagram assumes the issuer performs as promised. A call, tender, exchange, restructuring, conversion, default, or acceleration can change the timing or amount of cash flows.
| Term | What it tells the investor | Why it matters |
|---|---|---|
| Issuer | The legal entity that owes the debt | A parent, operating subsidiary, and finance subsidiary can have different assets and creditors |
| Principal or face amount | Amount used to calculate repayment and often coupon interest | Trading price can be above or below this amount |
| Coupon | Contractual interest rate or formula | Does not equal current yield or yield to maturity |
| Maturity | Scheduled principal repayment date | Longer maturities often have greater rate sensitivity |
| Seniority | Priority relative to other claims | Influences recovery, especially in distress |
| Collateral | Assets pledged for a secured obligation | Value, lien priority, and enforceability determine practical protection |
| Guarantee | Another entity’s contractual promise to support specified payments | Scope, release terms, and guarantor credit must be reviewed |
| Covenants | Actions the issuer must take or avoid | Can protect holders, require reporting, or limit transactions |
| Call or put | Right to redeem early or require repurchase | Changes expected cash flows and relevant yield measure |
| Currency | Currency in which payments are owed | Creates foreign-exchange exposure for investors using another base currency |
The prospectus, offering memorandum, indenture, and supplemental documents define these rights. A data-service description is useful for screening but does not replace the governing documents.
A company can issue bonds to:
Use of proceeds matters because borrowing that supports productive assets can have a different risk profile from borrowing that increases leverage without increasing durable cash flow. The financing decision should be analyzed with the issuer’s debt maturity schedule, liquidity, interest coverage, and covenant headroom.
In the primary market, the company sells a new issue through an offering process. Investors assess the initial spread, coupon, price, covenants, use of proceeds, and allocation. Proceeds ultimately fund the issuer after issuance expenses.
In the secondary market, existing holders trade the bond. The issuer generally does not receive the sale proceeds. Corporate bonds commonly trade over the counter through dealers or electronic request-for-quote systems rather than through one centralized exchange.
FINRA’s TRACE system disseminates execution information for eligible corporate bond trades. TRACE prints are historical transactions, not current bids or offers, and their usefulness depends on size, customer side, time, and market movement.
Assume a company has a five-year, $10,000 face-value bond with a 5% annual coupon. For simplicity, coupons are annual and the bond is noncallable.
The annual coupon is:
$10,000 x 5% = $500.
If investors now require a 6% yield, the estimated price is the present value of five $500 coupons plus $10,000 principal:
Price = $500 x [1 - (1.06)^-5] / 0.06 + $10,000 / (1.06)^5.
The result is approximately:
$2,106.18 + $7,472.58 = $9,578.76.
The bond trades below par because its 5% coupon is less than the market’s 6% required yield. If required yield fell below 5%, the same noncallable bond would generally trade above par.
This calculation assumes promised payments occur on time and uses one discount rate. Real corporate-bond valuation can require accrued interest, semiannual periods, a benchmark curve, credit spread, call scenarios, recovery assumptions, and transaction costs.
A corporate bond’s yield can be viewed as compensation for several components:
corporate yield approximately equals benchmark yield + credit and liquidity spread.
The spread is not pure expected profit. It can compensate for expected default loss, uncertainty, liquidity, downgrade risk, volatility, capital usage, and security-specific features.
If a five-year corporate bond yields 5.80% while a comparable Treasury benchmark yields 4.20%, its simple nominal spread is:
5.80% - 4.20% = 1.60%, or 160 basis points.
Different spread measures use different benchmarks and cash-flow assumptions. A nominal spread, G-spread, Z-spread, and option-adjusted spread should not be treated as interchangeable.
| Structure | Typical claim | Main limitation |
|---|---|---|
| Senior secured bond | Senior claim supported by specified collateral | Collateral value can fall, liens can be shared, and enforcement can take time |
| Senior unsecured bond | Senior contractual claim without specific pledged collateral | Competes for unencumbered value with other senior unsecured claims |
| Subordinated bond | Contractually ranks behind specified senior obligations | Loss severity can be greater in distress |
| Guaranteed bond | Has a contractual claim against one or more guarantors under stated terms | Guarantee may be unsecured, limited, or released under specified conditions |
| Convertible bond | Debt claim plus a right to convert under stated terms | Equity option, call terms, and dilution complicate valuation |
Priority does not determine recovery by itself. Entity structure, collateral location, intercompany claims, pension and tax obligations, insolvency law, and administrative costs can change the outcome.
An analyst should review both the issuer and the specific instrument:
Consolidated financial statements can obscure which subsidiary owns an asset or owes a liability. Creditor analysis must follow legal entities and claim priority.
