Convertible Bonds and Hybrid Securities › Practical Considerations

Understanding convertible bonds from both issuer and investor perspectives clarifies why these instruments exist and how credit risk affects their behavior.

Companies choose convertible bonds for several strategic reasons:

Lower coupon cost: The conversion feature is valuable, allowing issuers to pay 2-4% lower coupons than straight debt. For a company with limited cash flow, this reduced interest burden can be significant, preserving cash for operations or growth investments.

Delayed dilution: If management believes the stock is undervalued, a convertible allows future equity issuance at a higher price rather than issuing shares today. This helps companies that need capital but want to avoid selling equity at depressed prices.

Access to capital: Some growth companies may not be able to issue straight debt at reasonable rates but can access the convertible market where equity-oriented investors accept more credit risk. The conversion feature provides compensation for credit risk that would otherwise make the debt unattractive.

Investor base diversification: Convertibles attract different investors than straight equity or debt, potentially broadening the company's investor base. This diversification can improve liquidity and reduce the company's cost of capital over time.

From your perspective, convertibles offer several attractive characteristics that are difficult to replicate with other securities:

Asymmetric returns: Participation in equity upside with bond-like downside protection (subject to credit risk). This profile appeals to you if you want equity exposure but cannot tolerate the full volatility of stock ownership.

Yield with growth potential: Higher income than common stock while maintaining equity exposure. This combination is particularly valuable in low interest rate environments where income is scarce.

Risk management: Lower volatility than the underlying stock due to the bond floor. If you have volatility constraints, convertibles can provide equity-like returns with reduced risk.

Convertible arbitrage: Hedge funds often buy convertibles and short the underlying stock, extracting value from the volatility embedded in the conversion option. This strategy involves complex delta hedging that we'll explore further in Part III when we cover option risk management.

The bond floor in a convertible is only as good as the issuer's credit quality. If the company approaches financial distress, both the equity and debt components decline together, creating a correlation that reduces the effectiveness of the bond floor protection:

• The stock price falls, reducing conversion value
• Credit spreads widen, pushing down the straight bond value
• In bankruptcy, convertible bondholders are typically senior to equity but may receive significantly less than par

This credit-equity correlation means convertibles offer less downside protection than their structure might suggest, particularly for lower-rated issuers. You should analyze the issuer's credit fundamentals alongside the convertible's equity characteristics. A convertible on a company with weak credit may provide far less protection than the theoretical bond floor suggests.
