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

FeatureDescription
IssuerCorporations (public and private)
Maturities1-30 years (typically 5-10 years)
InterestUsually semi-annual coupon payments
TradingMost trade over-the-counter (OTC)
Credit RiskVaries widely by issuer
Tax TreatmentFully taxable (federal, state, local)

Secured vs. Unsecured Bonds

Secured Bonds (Backed by Collateral)

TypeCollateralRisk/Return
Mortgage BondsReal property (real estate, land)Lower yield
Equipment Trust CertificatesEquipment (railroads, airlines, ships)Lower yield
Collateral Trust BondsFinancial assets (stocks, bonds)Lower yield

Advantage: If issuer defaults, bondholders can claim specific assets.

Unsecured Bonds (Debentures)

TypeCharacteristicsRisk/Return
Senior DebenturesPaid before subordinated debtModerate yield
Subordinated DebenturesPaid after senior debtHigher 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:

PriorityClaim Type
1 (Highest)Secured bondholders (to extent of collateral)
2Senior unsecured bondholders
3Subordinated bondholders
4Preferred stockholders
5 (Lowest)Common stockholders

Key Point: Bondholders are paid before stockholders in bankruptcy.


Special Bond Features

Callable Bonds

FeatureDescription
Call FeatureIssuer can redeem before maturity
Call ProtectionPeriod when bond cannot be called
Call PremiumAmount above par paid at call
BenefitIssuer can refinance at lower rates
RiskLimits investor upside; reinvestment risk

When Called: Interest rates have fallen—issuer refinances at lower rate, investor loses high-coupon bond.

Putable Bonds

FeatureDescription
Put FeatureInvestor can force early redemption
BenefitProtection against rising rates
YieldLower 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

FeatureDescription
ConversionCan exchange for common stock
Conversion RatioNumber of shares per bond
Conversion PriceImplied price per share
YieldLower than non-convertible (equity upside)
Best WhenStock 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

FeatureDescription
InterestNone—sold at deep discount
Interest Rate RiskMaximum (long duration)
Reinvestment RiskZero
TaxationAnnual phantom income tax

Credit Ratings

Credit ratings assess the probability of default:

S&P/FitchMoody'sClassificationRisk Level
AAAAaaPrimeLowest risk
AA+, AA, AA-Aa1, Aa2, Aa3High gradeVery low
A+, A, A-A1, A2, A3Upper mediumLow
BBB+, BBB, BBB-Baa1, Baa2, Baa3Investment grade cutoffModerate
BB+, BB, BB-Ba1, Ba2, Ba3SpeculativeHigher
B+, B, B-B1, B2, B3Highly speculativeHigh
CCC and belowCaa and belowSubstantial riskVery high
DCIn defaultMaximum

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 BehaviorIndicates
WideningIncreased credit concern; more risk aversion
NarrowingImproved 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:

  1. Secured vs. unsecured: Mortgage bonds, debentures
  2. Seniority: Secured > Senior unsecured > Subordinated > Equity
  3. Callable bonds: Benefit issuer; reinvestment risk for investor
  4. Convertible bonds: Exchange for stock; lower coupon
  5. 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
