Why Your Borrowing Base Is Smaller Than Your AR Aging
A CFO pulls the AR aging. Gross receivables show $18 million. The borrowing base certificate comes back from the lender showing eligible AR of $11 million. Seven million dollars of receivables have been excluded. The CFO wants to know where the money went.
The answer is ineligibles. Every ABL facility defines eligible accounts receivable in the negative -- listing categories that are excluded from the borrowing base -- and then applies an advance rate (typically 80 to 85 percent) to what remains. Understanding which categories of receivables are ineligible, and why, is the difference between a facility that gives you the availability you need and one that leaves you permanently short of your credit limit.
At Don Clarke Enterprises, we build borrowing base projections before a single lender sees a deal, precisely because discovering $7 million of ineligibles at the field exam stage is the fastest way to blow up a financing. Donald Clarke has been working inside ABL borrowing base mechanics since 1986 -- he authored Asset Based Lending Disciplines, the first textbook on the discipline, and has trained more than 5,000 lending professionals at institutions including GE Capital, JP Morgan Chase, Lloyds, and Barclays on exactly this material. Here is what the ineligible categories actually look like in practice, why they exist, and what a borrower can do about them.
The Core Principle: Anything Potentially Uncollectible Is Not Lendable
ABL is first-lien senior debt secured by the collateral. Every lender underwrites to a liquidation outcome. The borrowing base is not a measure of your business value -- it is a measure of what the lender can reasonably expect to collect if they had to liquidate the collateral tomorrow. Anything that introduces meaningful risk of non-collection gets excluded.
That principle drives the eight standard ineligible categories that show up in nearly every ABL credit agreement in the market.
The Eight Standard Ineligible Categories
1. Past Due Receivables
The most common exclusion. Industry convention is that any invoice unpaid 90 days from invoice date or 60 days past its stated due date is considered past due and ineligible. The logic: if a customer has not paid in three times the standard payment term, there is a real risk they never will.
The specific threshold is negotiable and should be negotiated. A food distributor selling under Perishable Agricultural Commodities Act terms of net 10 days should have a different past-due definition than a capital equipment seller selling under net 90. Accepting the lender's default 90-day boilerplate when your industry runs longer terms is a common and avoidable mistake.
2. Cross-Aged Receivables
If a meaningful portion of a single customer's balance is past due -- typically 20 to 50 percent depending on the agreement -- the entire balance from that customer becomes ineligible, including invoices that are not themselves past due. The rationale is that customers with a pattern of delinquency on part of their account are high risk across the whole account.
This is the exclusion that surprises borrowers most. A customer with $500,000 of current receivables and $100,000 aged over 90 days gets the entire $600,000 excluded once the 20 percent cross-age threshold trips. Managing collections to prevent cross-aging is one of the highest-return operational disciplines a borrower can build. Our guide to borrowing base monitoring covers the collection cadence and aging reviews that prevent cross-age surprises.
3. Concentration Limits
Lenders cap how much of the borrowing base any single customer can represent. A typical concentration limit is 15 to 25 percent, though stronger credits (large, investment-grade customers with historically clean payment behavior) sometimes get higher individual caps. Balances in excess of the cap are excluded as ineligible.
The logic is diversification. If 40 percent of your receivables come from one customer and that customer disappears tomorrow, the collateral base collapses. Concentration limits protect the lender against that tail risk. On your side, this is the ineligible category where advisor negotiation matters most -- custom concentration caps for high-quality customers can recover millions of dollars of availability for the right borrower.
4. Contra Accounts and Setoff Receivables
When your customer is also your vendor -- you owe them money and they owe you money -- the lower of the two balances is excluded as ineligible. The reasoning is mechanical: in a liquidation, the customer would net the payable against the receivable and pay only the difference, so the lender cannot collect on the gross.
Contra exposures are often invisible until a field exam surfaces them. Manufacturers who buy inputs from customers who also buy finished goods, distributors with rebate arrangements, and service companies with barter elements all discover contra ineligibles at their first exam. The fix is clean visibility: run a monthly contra report, not just an AR aging, and price contra into operational decisions.
5. Foreign Receivables
Accounts receivable from customers outside the U.S. (and sometimes Canada) are generally ineligible unless supported by additional security -- typically a letter of credit from a U.S. bank on the customer's behalf or foreign credit insurance through Euler Hermes, Atradius, Allianz Trade, or similar. The reason is jurisdictional: U.S. UCC filings do not reach a Mexican, Brazilian, or German debtor, and enforcement in foreign courts is slow and uncertain.
Exporters who do meaningful volume internationally should build credit insurance into the commercial model from day one. The cost of insurance is typically 20 to 60 basis points of insured sales -- modest against the cost of excluding those receivables entirely from the borrowing base. Some lenders will accept insured foreign AR up to the insurance limit at full eligibility.
6. Government Receivables Without Assignment of Claims
Receivables due from U.S. federal government agencies are generally ineligible unless an Assignment of Claims Act filing is in place. Federal receivables are outstanding credits -- they get paid -- but without the Assignment of Claims, the government is only required to pay the contractor, not the lender. If the contractor collects and does not remit, the lender has no recourse against the government.
Assignment of Claims is a specific filing process administered at the contract level. It can take 30 to 60 days per contract and requires lender cooperation. Government contractors who plan to use ABL should build Assignment of Claims into the contract lifecycle. State and local government receivables face similar but jurisdiction-specific issues.
7. Affiliate and Intercompany Receivables
Receivables due from affiliates, parent companies, subsidiaries, or other related parties are ineligible, full stop. The logic is that related-party receivables do not represent arms-length economic exposure and are not reliable collateral in a distress scenario. A parent company owed $4 million by a subsidiary is not going to sue the subsidiary to collect.
For consolidated groups, this is a structural issue rather than an operational one. Borrowers with meaningful intercompany receivables should review their legal structure with counsel before pursuing ABL -- sometimes restructuring the entity relationships unlocks meaningful availability.
8. Disputed, COD, or Bill-and-Hold Receivables
Several sub-categories fall under this umbrella: receivables subject to an active customer dispute, cash-on-delivery accounts (which should not be on the aging in the first place), bill-and-hold arrangements where goods have not physically shipped, consignment inventory that has not yet been sold through, and progress billing on incomplete projects. All are excluded because the underlying obligation is contingent, disputed, or not yet fully earned.
Bill-and-hold and consignment deserve specific attention because they violate UCC rules on what constitutes a valid receivable. Companies that use bill-and-hold as a revenue recognition mechanism (often to hit quarterly targets) discover in field exam that those invoices cannot be pledged. The commercial discipline and the collateral discipline have to be aligned.
The Dilution Reserve on Top of Ineligibles
Even after ineligibles are removed, lenders apply a dilution reserve to the remaining eligible pool. Dilution is the difference between the face amount of receivables billed and the cash actually collected -- the haircut from returns, chargebacks, rebates, early-payment discounts, warranty claims, and disputes. Dilution of 5 percent or less is considered clean and typically does not drive a punitive reserve. Dilution above 5 to 10 percent triggers an explicit dilution reserve, commonly calculated using a formula: Reserve = (Dilution % minus Threshold) divided by (1 minus Dilution %).
Dilution reserves come off availability after ineligibles are removed. So a borrower with $18 million of gross AR, $4 million of ineligibles, and 8 percent dilution against a 5 percent threshold would see eligible AR of $14 million reduced by a dilution reserve of approximately $450,000 -- before the 85 percent advance rate is applied. The compounding effect is why clean operational discipline matters so much.
How to Protect Availability Before It Becomes a Problem
Five operational disciplines move real dollars.
Run a Pre-Submission Eligibility Scrub
Before submitting a deal to any lender, run your AR aging against the likely ineligible categories: past due over 90 days, cross-aged exposures, customers over concentration limits, contra balances, foreign AR without insurance, government AR without assignment. Build your own projected borrowing base. If the projection shows materially less than you expected, you have a problem to solve before a field examiner finds it. The ABL credit package we build for every client includes this projection as a core component.
Collect Aggressively on the 60-to-89-Day Bucket
Every dollar that crosses the 90-day mark gets excluded. Worse, it can cross-age the entire balance from that customer. A disciplined collections function that aggressively follows up in the 60-to-89-day window saves more availability than almost any other operational improvement.
Negotiate Concentration Caps Customer-by-Customer
Standard concentration caps are a starting point, not an ending point. Large, creditworthy customers with clean payment histories should be negotiated up to custom caps -- 35, 40, or even 50 percent in some cases. This is one of the highest-leverage parts of ABL term sheet negotiation for concentrated borrowers.
Insure Foreign AR Before the Deal Goes Out
If you have meaningful foreign receivables, have credit insurance in place before the lender sees the deal. An insured foreign receivable from a Tier 1 European customer is often eligible at the same advance rate as a domestic receivable. An uninsured foreign receivable is zero.
Clean Up Contra Relationships
If the same counterparty sits on both your AR aging and your AP aging, that is a contra exposure. Understand it, quantify it, and where possible negotiate cleaner commercial arrangements. The cost of restructuring a contra relationship is often smaller than the cost of the ineligible it creates.
Why Ineligibles Get Weaponized by Lenders
In healthy deals, eligibility definitions operate mechanically and predictably. In stressed deals, they become tools. A lender losing conviction on a credit can tighten cross-age thresholds, lower concentration caps, add dilution reserves, or expand the definition of ineligibles through the discretionary reserve authority embedded in most ABL credit agreements. Availability shrinks, the borrower runs out of working capital, and the facility moves toward default.
This is why the precision of eligibility definitions and the standard for discretionary lender actions matters enormously at the term sheet stage. We covered the specific protections in our post on ABL term sheet negotiation. A reasonable credit judgment standard with defined notice periods and cure rights is different from an unconstrained discretion. One is manageable in a downturn. The other is not.
Why DCE
Every deal we place includes a detailed borrowing base projection, a pre-submission eligibility scrub, and a negotiation focused on eligibility definitions and reserve standards that will hold up when conditions are not easy. We do not just place the loan -- we structure the deal so that the borrowing base actually produces the availability the borrower needs.
Don Clarke founded Asset Based Lending Consultants in 1986 and has spent four decades training the people who now run the underwriting desks at most major ABL shops. The borrowing base frameworks they use came out of that discipline. That gives every deal we place an advantage that comes from knowing not just how the rules work, but why they were written the way they were written.
We do not consult. We execute.
