The Underwriting Question Every Credit Team Must Answer
You have completed your EBITDA normalization, modeled three cash flow scenarios, and cleared credit committee. The term sheet is signed. Now comes the question that will determine whether your structural protections hold when the borrower hits a rough patch eighteen months from now: Does your covenant package actually give you the information and leverage you need, early enough to act?
Covenant design is not a legal formality. It is the early-warning architecture of your credit investment. As the institutional credit market has learned through high-profile liability management exercises (LMEs) involving borrowers like J. Crew, Serta, and Pluralsight, loose documentation and poorly defined financial metrics can allow borrowers to strip collateral, incur priming debt, or pit lenders against one another, all without triggering a technical default. According to T. Rowe Price / OHA’s 2026 Credit Investor’s Checklist, documentation and structuring expertise at underwriting are now considered a primary driver of long-term credit performance, not a secondary concern.
This article teaches how experienced private credit teams build, calibrate, and monitor covenant packages, from initial threshold-setting through ongoing portfolio surveillance.
The Analytical Framework: Three Layers of Covenant Protection
A well-structured covenant package operates across three layers, each designed to catch deterioration at a different stage of credit stress:
- Financial Maintenance Covenants: Tested quarterly, these require the borrower to actively maintain prescribed financial ratios. They are the primary trip wire in direct lending transactions.
- Incurrence Covenants: Tested only when the borrower takes a specific action (e.g., incurring additional debt, making an acquisition, paying a dividend), these limit optionality rather than signal ongoing deterioration. Broadly syndicated loans (BSLs) are often “covenant-lite” and rely almost exclusively on incurrence tests.
- Negative Pledge and Basket Controls: These restrict specific behaviors: asset disposals, subsidiary investments, affiliate transactions, and permitted debt baskets. Tight basket language closes the loopholes borrowers use in LMEs.
Example, Underwriting a $10M EBITDA Manufacturing Company: Assume you are structuring a $35M senior secured term loan (3.5x total leverage) against a manufacturer with $10M in trailing EBITDA, $2.5M in annual capex, and a seasonal cash conversion cycle that compresses Q1 liquidity. Your base covenant package should include: (1) a Total Net Leverage covenant set at 5.0x, a 43% EBITDA haircut from closing, tested quarterly; (2) a Fixed Charge Coverage Ratio (FCCR) covenant of no less than 1.10x, ensuring debt service, capex, and tax obligations are covered by cash earnings; and (3) a minimum liquidity covenant of $2M unrestricted cash or revolver availability, specifically designed to protect against the Q1 seasonal trough. Each threshold is set with deliberate headroom from the base case, but not so much headroom that the covenant is effectively meaningless.
Walking Through the Calculations: Setting Covenant Levels That Work
The cardinal error in covenant-setting is anchoring thresholds too close to the base case. This creates a false sense of security, the covenant tests at closing, then never trips again until the company is already in freefall.
Leverage Covenant Calibration: Begin with your underwritten EBITDA. Apply a downside scenario, typically a 20–30% EBITDA reduction reflecting either a cyclical contraction or a single large customer loss. In our manufacturing example, a 25% EBITDA haircut reduces earnings from $10M to $7.5M. At $35M of debt, that moves the leverage ratio from 3.5x to 4.7x. Your covenant threshold of 5.0x provides only 6% additional buffer beyond the downside case. That is the intended design: covenants should trip in a realistic downside, not only in a catastrophic collapse.
FCCR Calculation: Fixed Charge Coverage = (EBITDA – Capex – Cash Taxes – Cash Interest) / (Scheduled Debt Amortization + Cash Interest). Using base case figures: ($10M – $2.5M – $0.8M – $2.1M) / ($1.75M + $2.1M) = $4.6M / $3.85M = 1.19x. This sits only 8% above the 1.10x covenant floor, which is appropriate. A covenant floor set at 1.50x on this structure would be unrealistically punitive; a floor at 0.90x would be functionally decorative.
Stress Scenario: Under the 25% EBITDA haircut, FCCR compresses to ($7.5M – $2.5M – $0.8M – $2.1M) / $3.85M = 0.54x, a clear covenant breach that brings the lender to the table eighteen months before a liquidity crisis, not after.
What Institutional Lenders Require: Market Standards and Red Flags
Institutional direct lenders have materially tightened documentation standards following the wave of LMEs between 2020 and 2025. According to PGIM’s large cap private credit research, tighter security documentation (including restricted basket language and clearly defined EBITDA definitions) has contributed to historically lower default rates and higher recovery rates in large cap direct lending relative to the broadly syndicated market.
The OHA / T. Rowe Price framework further illustrates the economic consequence of recovery rate differentials: two portfolios with identical nominal spreads and default rates can produce a 44% divergence in realized spread once loss severity is applied. This underscores why covenant protections that preserve collateral access and accelerate lender intervention are not defensive paperwork; they are return-generating tools.
Sophisticated lenders also rely on portfolio-level risk models. Moody’s Analytics RiskFrontier methodology demonstrates how marginal contribution to portfolio risk, Value-at-Risk, and expected shortfall calculations must incorporate each instrument’s covenant structure, collateral position, and recovery assumptions, not just its nominal spread.

- Covenant-lite BSL structures carry materially higher LME risk versus maintained covenant direct lending structures, documented across J. Crew, Serta, and Pluralsight restructurings
- Large cap private credit has demonstrated lower historical default rates relative to BSL comparables when tighter documentation is maintained, PGIM Private Credit, 2025
Red Flags in Covenant Packages to Reject or Renegotiate:
- EBITDA definitions that allow unlimited “run-rate” or “synergy” addbacks without a lookback cap (typically 18–24 months is the institutional standard)
- Leverage covenant thresholds set at or above 6.5x with no stepdown schedule
- Unrestricted subsidiary baskets that are undefined or uncapped, the primary J. Crew structural exploit
- Permitted debt baskets defined as a percentage of EBITDA rather than a fixed dollar cap, which expand precisely when the borrower is most stressed
- No minimum liquidity covenant in businesses with seasonal or cyclical cash flow patterns
Covenant Underwriting Checklist: Before You Sign the Credit Agreement
- Define EBITDA precisely. Cap pro forma addbacks at 18–24 months. List permitted and excluded items explicitly. Require a reconciliation schedule in every compliance certificate.
- Set leverage thresholds with a downside stress overlay. Apply a minimum 20% EBITDA haircut to your base case and confirm the covenant trips under that scenario.
- Include FCCR and liquidity covenants alongside leverage. Leverage alone does not capture cash flow timing risk or seasonal liquidity compression.
- Restrict the unrestricted subsidiary basket. Define which entities qualify, cap the basket in absolute dollar terms, and require lender consent for reclassification above the threshold.
- Require quarterly compliance certificates with supporting schedules. Each certificate should include a full EBITDA bridge from reported financials to covenant EBITDA, signed by the CFO.
- Build a covenant monitoring calendar. Test dates, grace periods, and cure right timelines should be tracked in your portfolio management system, not managed manually.
- Document the cure mechanism clearly. Equity cure rights, if permitted, should be capped (typically two consecutive quarters, five total over the loan life) and require cash injection, not paper EBITDA.
Key Takeaways
- 📌 Covenants are early-warning systems, not legal formalities. They must be calibrated to trip in a realistic downside scenario, not only in a worst-case collapse.
- 📌 EBITDA definition is the battleground. Unlimited addbacks and undefined pro forma adjustments hollow out the numerator of every financial ratio in the credit agreement.
- 📌 Recovery rates drive realized returns more than nominal spread. Structural protections that preserve collateral access and accelerate lender intervention materially improve loss-adjusted performance.
- 📌 Basket language is the LME exploit vector. Unrestricted subsidiary baskets, unlimited debt baskets, and undefined asset sale permissions are the mechanisms through which borrowers circumvent lender protections in out-of-court restructurings.
- 📌 Monitoring is as important as documentation. A well-drafted covenant package that is tracked quarterly with full financial schedules and portfolio-level risk models, including marginal contribution to concentration risk, is the institutional standard for managing credit through cycles.
