Corporate Bonds
Corporate bonds are debt securities issued by corporations to raise capital. They offer higher yields than government securities but carry additional credit risk.
Corporate Bond Basics
| Feature | Description |
|---|---|
| Issuer | Corporations (public and private) |
| Maturities | 1-30 years (typically 5-10 years) |
| Interest | Usually semi-annual coupon payments |
| Trading | Most trade over-the-counter (OTC) |
| Credit Risk | Varies widely by issuer |
| Tax Treatment | Fully taxable (federal, state, local) |
Secured vs. Unsecured Bonds
Secured Bonds (Backed by Collateral)
| Type | Collateral | Risk/Return |
|---|---|---|
| Mortgage Bonds | Real property (real estate, land) | Lower yield |
| Equipment Trust Certificates | Equipment (railroads, airlines, ships) | Lower yield |
| Collateral Trust Bonds | Financial assets (stocks, bonds) | Lower yield |
Advantage: If issuer defaults, bondholders can claim specific assets.
Unsecured Bonds (Debentures)
| Type | Characteristics | Risk/Return |
|---|---|---|
| Senior Debentures | Paid before subordinated debt | Moderate yield |
| Subordinated Debentures | Paid after senior debt | Higher yield |
Debentures are backed only by the issuer's creditworthiness and general assets—no specific collateral.
Seniority Hierarchy (Liquidation Order)
If a company goes bankrupt, claims are paid in this order:
| Priority | Claim Type |
|---|---|
| 1 (Highest) | Secured bondholders (to extent of collateral) |
| 2 | Senior unsecured bondholders |
| 3 | Subordinated bondholders |
| 4 | Preferred stockholders |
| 5 (Lowest) | Common stockholders |
Key Point: Bondholders are paid before stockholders in bankruptcy.
Special Bond Features
Callable Bonds
| Feature | Description |
|---|---|
| Call Feature | Issuer can redeem before maturity |
| Call Protection | Period when bond cannot be called |
| Call Premium | Amount above par paid at call |
| Benefit | Issuer can refinance at lower rates |
| Risk | Limits investor upside; reinvestment risk |
When Called: Interest rates have fallen—issuer refinances at lower rate, investor loses high-coupon bond.
Putable Bonds
| Feature | Description |
|---|---|
| Put Feature | Investor can force early redemption |
| Benefit | Protection against rising rates |
| Yield | Lower than comparable non-putable bonds |
When Exercised: Interest rates have risen—investor "puts" bond back to get cash to reinvest at higher rates.
Convertible Bonds
| Feature | Description |
|---|---|
| Conversion | Can exchange for common stock |
| Conversion Ratio | Number of shares per bond |
| Conversion Price | Implied price per share |
| Yield | Lower than non-convertible (equity upside) |
| Best When | Stock price rises significantly |
Example:
- Bond converts to 40 shares (conversion ratio)
- $1,000 par ÷ 40 shares = $25 conversion price
- If stock rises above $25, conversion becomes attractive
Zero-Coupon Bonds
| Feature | Description |
|---|---|
| Interest | None—sold at deep discount |
| Interest Rate Risk | Maximum (long duration) |
| Reinvestment Risk | Zero |
| Taxation | Annual phantom income tax |
Credit Ratings
Credit ratings assess the probability of default:
| S&P/Fitch | Moody's | Classification | Risk Level |
|---|---|---|---|
| AAA | Aaa | Prime | Lowest risk |
| AA+, AA, AA- | Aa1, Aa2, Aa3 | High grade | Very low |
| A+, A, A- | A1, A2, A3 | Upper medium | Low |
| BBB+, BBB, BBB- | Baa1, Baa2, Baa3 | Investment grade cutoff | Moderate |
| BB+, BB, BB- | Ba1, Ba2, Ba3 | Speculative | Higher |
| B+, B, B- | B1, B2, B3 | Highly speculative | High |
| CCC and below | Caa and below | Substantial risk | Very high |
| D | C | In default | Maximum |
Investment Grade: BBB-/Baa3 and above High Yield (Junk): BB+/Ba1 and below
Credit Spread
Credit spread = Corporate bond yield − Treasury yield of same maturity
| Spread Behavior | Indicates |
|---|---|
| Widening | Increased credit concern; more risk aversion |
| Narrowing | Improved confidence; more risk appetite |
Credit spreads typically widen during recessions and narrow during expansions.
In Practice: How Investment Advisers Apply This
Portfolio construction:
- Use investment-grade corporates for income with moderate risk
- Consider high-yield for aggressive income strategies
- Convertibles for equity-like upside with bond-like downside
- Match credit quality to client risk tolerance
Risk considerations:
- Callable bonds have reinvestment risk
- Subordinated debt has higher loss severity in default
- Credit spreads indicate market sentiment about default risk
On the Exam
The Series 65 exam tests your understanding of:
- Secured vs. unsecured: Mortgage bonds, debentures
- Seniority: Secured > Senior unsecured > Subordinated > Equity
- Callable bonds: Benefit issuer; reinvestment risk for investor
- Convertible bonds: Exchange for stock; lower coupon
- Credit ratings: Investment grade (BBB-/Baa3 and above) vs. junk
Expect 2-3 questions on corporate bonds. Common formats include identifying bond types and understanding callable/convertible features.
Key Takeaways
- Secured bonds are backed by specific collateral; debentures are unsecured
- Seniority: Secured > Senior > Subordinated > Preferred > Common
- Callable bonds benefit the issuer (can refinance at lower rates)
- Putable bonds benefit the investor (can sell back if rates rise)
- Convertible bonds have lower yields but stock upside potential
- Investment grade: BBB-/Baa3 and above; Junk: BB+/Ba1 and below
- Credit spreads widen when risk increases; narrow when confidence returns
- All corporate bond interest is fully taxable
