Understanding Bond Indentures and Covenants

The fine print in your bond investment determines whether you recover 72 cents on the dollar in default or just 61 cents. That 11-percentage-point gap represents the difference between covenanted and covenant-lite debt (S&P Global Ratings, 2010-2023 data). If you own bonds without understanding their indenture protections, you are flying blind into credit risk.

What the Indenture Actually Does

A bond indenture is the legal contract between issuer and bondholders. It specifies everything that matters: interest payment dates, maturity, redemption rights, and the covenants that constrain issuer behavior. A trustee (typically a commercial bank with fiduciary duties) monitors compliance and enforces terms when the issuer stumbles.

Think of it as the constitution for your creditor relationship. The issuer cannot change the rules unilaterally. But here is the critical insight: not all constitutions are created equal. A 2015 high-yield indenture might have 15-20 protective covenants. A 2024 covenant-lite deal might have 3-5 (the bare minimum). That erosion happened gradually, then suddenly.

The Trustee's Role

The trustee collects interest payments, receives financial reports, and (crucially) notifies bondholders of defaults. Pre-default, the trustee monitors compliance. Post-default, the trustee enforces remedies. What the trustee cannot do: prevent bad covenant terms from being agreed in the first place. That is your job before you invest.

Affirmative Covenants: What the Issuer Must Do

Affirmative covenants are promises to take specific actions. They create your information rights and operational floor. Miss these requirements, and you have an early warning before financial distress becomes a default.

Core Affirmative Covenants

• Financial Reporting: Deliver audited annual statements within 90 days of fiscal year-end; quarterly statements within 45 days. Private issuers (144A bonds) owe these directly to bondholders since they do not file with the SEC.

• Maintenance of Existence: The issuer must remain a valid legal entity and maintain licenses needed for operations. Sounds basic until a company tries to restructure by dissolving the entity you lent to.

• Insurance Requirements: Maintain adequate property and liability insurance. A factory fire without insurance destroys your collateral value.

• Compliance Certificate: Officers must certify quarterly that no default exists. This creates personal accountability and legal liability for false statements.

The Ratio Trap

Maintenance covenants require the issuer to stay within financial guardrails at all times (or at each testing date). The most common:

A company breaching 4.5x Debt/EBITDA triggers a technical default. Lenders can accelerate the debt, force a restructuring, or negotiate a waiver (usually for a fee). This is your early warning system. Remove maintenance covenants, and you have no warning until the company misses an actual payment.

Negative Covenants: What the Issuer Cannot Do

Negative covenants restrict actions that could harm bondholders. These are the sharp teeth that prevent value leakage to shareholders or other creditors.

Critical Restrictions

• Limitation on Indebtedness: Cannot incur debt above specified thresholds without meeting ratio tests. A company at 5x leverage might be prohibited from borrowing more until it deleverages to 4.5x. (The 2024 market standard: 76% of firms with 5x leverage can actually incur debt above 6x due to weak covenant definitions.)

• Restricted Payments: Limits dividends, stock buybacks, and payments to subordinated debt. The typical basket: 50% of cumulative net income since issuance, plus certain credits. This stops shareholders from draining cash before a default.

• Asset Sale Covenant: Requires sale proceeds to be reinvested in the business or used to repay debt within 365-450 days. Prevents the "sell the crown jewels and run" scenario.

• Change of Control Put: Gives bondholders the right to sell back at 101% of par if the company is acquired. Private equity buyers hate this covenant (which is precisely why you want it).

• Limitation on Liens: Prevents securing new debt ahead of your bonds without equally securing yours. The principle: no one jumps the priority line without your consent.

Incurrence vs. Maintenance: A Critical Distinction

Here is where covenant-lite deals catch investors. Incurrence covenants are only tested when the company takes an action (borrowing more, paying a dividend). Maintenance covenants are tested continuously or at regular intervals.

The difference is timing. With maintenance covenants, you learn about financial deterioration early (the company breaches 4.5x leverage even though it is still paying interest). With incurrence-only covenants, you learn nothing until the company tries to do something new or misses a payment. By then, recovery rates have already collapsed.

High-yield bonds traditionally used incurrence tests. Investment-grade relied on financial strength rather than legal protections. Leveraged loans historically used maintenance covenants. The post-2015 shift to covenant-lite eliminated maintenance tests from 93% of new leveraged loans (LSTA 2024 data).

How Covenants Impact Credit Risk

The recovery data tells the story. Moody's found that senior unsecured bonds recovered 42% in economic expansions but only 31% in recessions (1982-2014 data). Research confirms that covenant restrictions on investment and financing policy significantly increase bondholder recovery rates (Jankowitsch & Subrahmanyam, 2014). Covenant-lite structures reduce creditor ability to renegotiate early, delaying intervention until value erosion is severe (Becker & Ivashina, 2016). Covenants help preserve value before those recession defaults occur.

The Covenant-Recovery Link

The mechanism is straightforward. Maintenance covenants force early action. When a company breaches 4.0x leverage (but is still solvent), lenders can: negotiate for additional collateral, require prepayment from asset sales, block value-destroying acquisitions, prevent dividend leakage. By the time an incurrence-only borrower defaults, assets have often been stripped, collateral has been pledged elsewhere, or the company has deteriorated past the point of rescue.

Real-World Covenant Failure: The Liability Management Playbook

The 2020 Serta Simmons restructuring demonstrated how weak covenants enable "lender-on-lender violence." The company used loose documentation to create $1 billion in super-priority debt, subordinating existing lenders without their consent. The Fifth Circuit ruled in December 2024 that this violated pro rata distribution rights (a "sacred right" of lenders).

The J.Crew 2016 restructuring pioneered the "trap door" maneuver: transferring valuable intellectual property to unrestricted subsidiaries outside the collateral package. Lenders watched their security interest become worthless.

Both cases exploited weak or ambiguous covenant language. The market responded with "Serta blockers" (requiring unanimous consent for subordination) and "J.Crew blockers" (prohibiting IP transfer to unrestricted subs). If your bonds lack these blockers, you are vulnerable to the same playbook.

Your Covenant Checklist

Before investing in corporate bonds or credit funds, verify these protections exist:

Tier 1: Non-Negotiable

• Maximum leverage ratio with maintenance testing (not just incurrence)
• Restricted payments covenant limiting dividends and buybacks
• Change of control put at 101% of par
• Limitation on liens preventing senior debt ahead of you

Tier 2: Highly Important

• Financial reporting requirements with tight deadlines (45/90 days)
• Asset sale covenant requiring debt paydown
• Serta blocker (unanimous consent for subordination)
• J.Crew blocker (prohibits material IP transfer)

Tier 3: Watch For

• Definition of EBITDA (aggressive add-backs can hide leverage)
• Basket sizes for permitted actions (larger baskets = more flexibility for issuer)
• Carve-outs from negative covenants (read the exceptions carefully)

If Investing Through Funds

Ask your credit fund manager: What is your covenant screen? How do you handle covenant-lite exposure? What percentage of the portfolio has maintenance covenants? A fund manager who cannot answer these questions precisely is not doing credit analysis. The 61% vs. 72% recovery differential should inform every credit decision.

Bond covenants are your contractual defense against credit deterioration. The market has systematically weakened these protections since 2015. Knowing what you own (and what you are missing) is the difference between creditor and casualty.
