How Maintenance and Incurrence Covenants Govern Corporate Debt

The broadly syndicated leveraged loan market has undergone a structural transformation over the past decade, stripping away the early-warning systems that historically protected lenders. By the end of 2024, approximately 91.1% of outstanding US institutional leveraged loans were classified as "covenant-lite," according to PitchBook LCD data.

This shift fundamentally alters the balance of power between corporate borrowers and their creditors. At the center of this transition is the distinction between two legal mechanisms: maintenance covenants and incurrence covenants.[2]

The Mechanics of Maintenance Covenants

Maintenance covenants require a borrower to continuously satisfy specific financial ratios at regular intervals. Lenders test these metrics, such as the total debt-to-EBITDA ratio or the interest coverage ratio, at the end of every fiscal quarter.[2]

The borrower must pass the test regardless of whether it has taken any new strategic actions. If a company's earnings decline and push its leverage ratio above the contractual limit, a maintenance covenant is breached.[2]

This violation constitutes a technical event of default, granting lenders immediate leverage. The lenders gain the right to accelerate the loan, demanding immediate repayment of the principal.[2]

In practice, lenders rarely force an immediate bankruptcy over a technical breach. Instead, the maintenance covenant acts as a tripwire that brings the borrower back to the negotiating table.[6]

Lenders typically grant a waiver or amend the credit agreement in exchange for higher interest rates, additional collateral, or strict operational oversight. For traditional banks and private credit funds, this early intervention is a critical risk-management tool.[4]

It prevents a deteriorating company from taking on more risk or bleeding cash without lender supervision. However, for private equity sponsors, maintenance covenants represent a constant threat to their control over portfolio companies.[4]

The Mechanics of Incurrence Covenants

Incurrence covenants operate on an entirely different legal framework, functioning as gates rather than tripwires. These provisions are tested only when a borrower attempts to execute a specific, restricted action.[1]

Common triggers include incurring additional debt, paying a dividend to shareholders, or acquiring another company. If a company simply experiences declining revenues and its leverage ratio drifts upward, an incurrence covenant remains dormant.[2]

The borrower faces no penalty or technical default as long as it avoids the restricted actions. The lender has no contractual right to intervene, demand higher pricing, or force a restructuring.[2]

This structure mirrors the traditional protections found in the high-yield bond market, which has historically relied on incurrence tests. High-yield bonds are typically issued with seven-to-ten-year maturities and are designed to give the issuer operational flexibility.

The incurrence model assumes that bondholders do not want to actively manage the borrower's day-to-day finances. When a borrower does want to take a restricted action, it must prove that its pro forma financial metrics satisfy the incurrence test.[2]

For example, a company might be barred from raising new debt if its leverage ratio would exceed 5.0x after the transaction. However, complex credit agreements often include "baskets" that carve out exceptions to these rules.[2]

These baskets allow borrowers to execute limited transactions without meeting the primary ratio test. A general debt basket might permit a specific dollar amount of new borrowing regardless of the company's leverage.[6]

The Role of EBITDA Add-Backs

Over time, aggressive private equity sponsors have negotiated increasingly flexible baskets, further diluting the protective power of incurrence covenants. The effectiveness of any financial covenant depends entirely on how the underlying metrics are calculated.

In recent years, the definition of earnings before interest, taxes, depreciation, and amortization has become highly negotiated. Borrowers routinely include aggressive add-backs for projected cost savings or future synergies.

These adjustments artificially inflate the company's earnings figure, making its leverage ratio appear lower than it actually is. When a maintenance covenant relies on an inflated earnings metric, the tripwire is effectively moved further away.[2]

The lender loses the early warning signal that the covenant was originally designed to provide. Incurrence covenants are similarly weakened by these aggressive accounting adjustments.[6]

If a borrower wants to incur new debt, it can often use projected synergies to satisfy the required ratio test. This dynamic allows highly leveraged companies to continue borrowing even when their actual cash flow is deteriorating.[6]

Equity Cures and Sponsor Interventions

When a maintenance covenant breach is imminent, private equity sponsors often utilize a mechanism known as an equity cure. This provision allows the sponsor to inject fresh capital into the business to artificially boost the earnings metric for that specific quarter.

The cash is treated as earnings solely for the purpose of passing the covenant test. Equity cures provide a lifeline for struggling companies, preventing lenders from accelerating the debt or demanding punitive amendment fees.[2]

However, credit agreements typically limit how often a sponsor can use this tool. Most contracts restrict equity cures to no more than two consecutive quarters and cap the total number of uses over the life of the loan.[2]

For lenders, an equity cure is a double-edged sword. While it provides the company with much-needed liquidity, it also delays the comprehensive restructuring that the business might actually need.[6]

The Rise of Cov-Lite Loans

The sponsor retains control, but the underlying operational issues often remain unresolved until the cure rights are exhausted. The migration from maintenance to incurrence covenants in the leveraged loan market has been staggering.[1]

In 2007, just prior to the global financial crisis, covenant-lite loans accounted for roughly 10% of the market. By the end of 2024, that figure had eclipsed 91%, representing approximately $1.29 trillion in outstanding US leveraged loans.[1]

This explosion was driven by a fundamental shift in the investor base for syndicated loans. Traditional banks, facing stricter post-crisis capital requirements, retreated from holding risky corporate debt.[5]

They were replaced by institutional investors, primarily collateralized loan obligations and mutual funds, which prioritize yield and deployment over strict control. Private equity sponsors capitalized on this institutional demand to strip maintenance covenants from their buyout financings.[3]

"There's endless demand, especially from sponsors and their counsels, to create new avenues for weaknesses," said Derek Gluckman, vice president and senior covenant officer at Moody's.[3]

Sponsors argued that cov-lite structures prevent opportunistic lenders from extracting exorbitant amendment fees during temporary earnings dips. The result is a syndicated loan market where the vast majority of borrowers operate with bond-style flexibility.[6]

A company can watch its leverage ratio climb from 4.0x to 7.0x over several quarters without ever hearing from its lenders. The creditors are effectively locked out of the boardroom until the borrower actually misses an interest payment or attempts a restricted transaction.[6]

The Impact on Corporate Behavior

The absence of maintenance covenants changes how companies behave as their financial health deteriorates. A working paper from the Federal Reserve Bank of Boston examined the real-world effects of these different covenant structures.[1]

The researchers found that incurrence covenants create a distinct shock amplification mechanism long before a bankruptcy filing. When a company triggers an incurrence covenant restriction—meaning it is barred from taking actions like issuing debt—its investment rate drops by 1.8 percentage points.[1]

In contrast, violating a maintenance covenant leads to a smaller 0.9 percentage point drop in investment. The incurrence structure forces a more sudden and severe operational contraction when the limits finally bind.[1]

Firms also deleverage more aggressively under incurrence restrictions. The Boston Fed study noted that a company's debt-to-assets ratio decreases by an average of 2.7 percentage points following an incurrence trigger.[1]

A maintenance covenant violation results in a milder 1.6 percentage point reduction in the debt-to-assets ratio. These figures suggest that while incurrence covenants preserve equity control, they ultimately impose harsh constraints on a struggling business.[1]

Because the lenders cannot intervene early to force a gradual restructuring, the company must take drastic measures once its flexibility is exhausted. The delayed reckoning often leaves the borrower with fewer strategic options.[1]

Default Recoveries and the Cost of Delay

For lenders, the ultimate cost of trading maintenance covenants for incurrence covenants is measured in recovery rates during a default. Without an early tripwire, cov-lite borrowers tend to default later in their distress cycle.

By the time the company formally misses a payment, its enterprise value has often eroded significantly. Data from Moody's Ratings illustrates this penalty clearly.

For defaults occurring between 2023 and the first half of 2025, average first-lien recoveries on cov-lite loans stood at 57%. In comparison, loans that retained traditional maintenance covenants delivered an average first-lien recovery of 66% over the same period.

S&P Global Ratings found a similar historical gap when analyzing rated US first-lien term loans from 2010 through 2023. Their data showed that cov-lite term loans recovered approximately 11 percentage points less than their covenanted equivalents on a discounted basis.

The lack of early intervention directly translates to heavier losses for the creditor class. When a maintenance covenant is breached early, lenders can force the sponsor to inject fresh equity or mandate asset sales while valuations are still viable.[6]

Under a cov-lite structure, the sponsor can continue operating the business, potentially draining value, until the cash runs out entirely. The 9-to-11 percentage point recovery gap is the price institutional investors pay for that flexibility.[6]

The Private Credit Divide

While the broadly syndicated market has overwhelmingly embraced incurrence covenants, the rapidly growing private credit sector has largely held the line. Direct lenders, who hold loans on their own balance sheets rather than syndicating them, demand tighter controls.[4]

In the lower-middle market, maintenance covenants remain the standard operating procedure. A 2026 report analyzing KBRA Direct Lending Deals data found that only 14% of US direct lending transactions in 2025 featured a cov-lite structure.[4]

The vast majority of private credit deals retained at least one financial maintenance covenant. Direct lenders use these covenants to actively manage their portfolios and step in at the first sign of underperformance.[4]

This structural difference means that default statistics between the two markets are not directly comparable. In private credit, a covenant breach is often recorded as a default, triggering an immediate restructuring process.[4]

In the syndicated cov-lite market, a default is typically only recorded when the company actually fails to make a scheduled debt service payment. As the corporate debt landscape evolves, the divide between maintenance and incurrence covenants defines the boundary between active and passive lending.[6]

Private equity sponsors will continue to push for incurrence-only flexibility wherever the market allows. Lenders must weigh that flexibility against the proven historical cost of arriving late to a restructuring.[6]
