What are bond indenture covenants and how do affirmative covenants differ from negative covenants in practice?

Bond covenants are legally binding clauses in the bond indenture (the contract between issuer and bondholders) that restrict the issuer's behavior to protect creditors. They're one of the most practical topics in CFA Level I fixed income.

The Two Types

Affirmative (Positive) Covenants -- Things the issuer MUST do:

• Make timely interest and principal payments
• Maintain insurance on pledged assets
• File audited financial statements with the trustee
• Maintain specific financial ratios (e.g., interest coverage above 3.0x)
• Pay taxes and other senior obligations
• Comply with all applicable laws

Negative (Restrictive) Covenants -- Things the issuer MUST NOT do:

• Issue additional debt beyond a specified limit
• Pay dividends exceeding a certain amount or payout ratio
• Sell or pledge key assets without bondholder consent
• Merge with another company without assuming the debt obligations
• Allow total leverage to exceed a specified ratio
• Make loans or investments that exceed a threshold

Practical Example: Grantworth Energy Corp 6.5% Senior Notes (fictional)

Imagine you're analyzing a high-yield bond issued by an oil & gas company. The indenture might include:

Affirmative: Must maintain a minimum tangible net worth of $500 million and deliver quarterly unaudited and annual audited financials to the trustee.

Negative: Cannot incur additional secured debt if the total secured debt / total assets ratio would exceed 35%. Cannot pay dividends if cumulative dividends since issuance would exceed 50% of cumulative net income.

Why Covenants Matter for Valuation

Tighter covenants generally mean lower yield spreads because bondholders have better protection. A bond with strong negative covenants (can't lever up, can't strip assets) is safer than a 'covenant-lite' bond with minimal restrictions.

Covenant-Lite Loans: In leveraged lending (tested in CFA Level II credit analysis), 'cov-lite' structures have become common since 2013. These bonds have few or no maintenance covenants -- only incurrence-based tests that trigger when the issuer takes a specific action. This benefits issuers but increases credit risk for bondholders.

Exam Tip: A typical CFA Level I question will describe a covenant and ask you to classify it as affirmative or negative. Remember: affirmative covenants describe obligations (things to do); negative covenants describe restrictions (things not to do). If it starts with 'shall not' or 'must not,' it's negative.
