A covenant is a contractual promise in a loan agreement or bond indenture. Covenants exist because lenders hand over money today against repayment years from now; between those two dates, covenants define what the borrower must do, must not do, and must maintain — and they give lenders a seat at the table when things go wrong.
Affirmative covenants are the housekeeping promises: deliver audited financial statements and compliance certificates, pay taxes, maintain insurance and properties, comply with laws, and grant lenders inspection rights. They rarely drive negotiations but matter operationally — late financials are a common technical default.
Negative covenants restrict actions that could weaken the lender's position. The core set limits additional debt (debt covenant), liens on assets (negative pledge), asset sales, investments and acquisitions, dividends and share buybacks (restricted payments), transactions with affiliates, and mergers. In modern agreements, each restriction is softened by negotiated exceptions — "baskets" — sized as fixed dollar amounts, percentages of EBITDA or assets, or unlimited amounts subject to a ratio test.
Financial covenants set numerical thresholds, most commonly a maximum leverage ratio (net debt to EBITDA) or a minimum interest or fixed-charge coverage ratio. The crucial distinction is how they are tested. A maintenance covenant is tested every quarter regardless of what the borrower does: if leverage exceeds the ceiling, the borrower is in default and must seek a waiver or amendment. An incurrence covenant is tested only when the borrower acts — for example, it may incur new debt only if pro forma leverage stays under a ratio. Between actions, deterioration alone does not trip an incurrence test.
"Covenant-lite" (cov-lite) describes loans that carry no financial maintenance covenants for term lenders, relying instead on incurrence-style protections like a bond. Cov-lite became the norm for large broadly syndicated loans over the past decade. Often a "springing" maintenance covenant survives for the revolver only, tested when the revolver is drawn beyond a set percentage. Middle market and private credit loans more commonly retain at least one true maintenance covenant.
Why the distinction matters: maintenance covenants act as an early-warning tripwire, forcing the borrower to the table while enterprise value still covers the debt. In cov-lite structures, lenders may have no enforcement trigger until a missed payment, which typically happens later in a deterioration. Research and rating agency commentary generally associate cov-lite defaults with later intervention; recoveries depend heavily on the rest of the document.
Related terms worth knowing: EBITDA "add-backs" (adjustments — projected synergies, one-time costs — that inflate the EBITDA figure covenants are measured against), "cure rights" (a sponsor's contractual ability to inject equity to fix a covenant breach), "waiver" and "amendment" (lender consent to forgive or change a term, often for a fee), and "defaults" versus "events of default" (the latter, after notice and cure periods, permit acceleration).
Finally, covenant quality is now a discipline of its own. The gaps that matter most in stressed credits are the provisions that allow collateral or value to move beyond lenders' reach — unrestricted subsidiary transfers, non-pro-rata exchanges, and generous investment baskets. Reading the baskets, not just the ratios, is where modern covenant analysis lives.
