Refinancing a Fully Drawn Revolver: A Borrower’s Availability-Bridge Playbook

Refinancing a fully drawn revolver is different from refinancing a facility with ample unused availability. When the line is at or near its usable limit, every change in receivables, inventory, reserves, letters of credit, or collections can affect day-to-day liquidity while management is trying to complete a lender process. The practical starting point is not a request for a larger headline commitment. It is a lender-ready availability bridge that shows what is drawn, what collateral supports it, what must be paid at closing, and how the business expects to operate through the transition.

This guide is for CFOs, owners, controllers, and treasury teams considering a replacement working-capital facility while the current revolver is substantially or fully utilized. It is educational only. A prospective lender independently determines credit appetite, collateral eligibility, diligence, documentation, and approval; a refinance is not assured by a forecast, a borrowing-base calculation, or a prior facility size.

What “Fully Drawn” Actually Means

A revolver can be “fully drawn” in two different ways, and separating them matters. The first is a commitment constraint: the outstanding loans and letters of credit have reached the contractual commitment, even though the borrowing base might support more collateral value. The second is an availability constraint: the borrower has drawn substantially all of the amount supported by the current borrowing base after reserves, letters of credit, and other deductions. The second condition is usually more consequential in an ABL refinance because a new lender will focus on the collateral support, not only the old commitment amount.

Situation	What it may indicate	Core borrower question
Commitment is full; borrowing base has excess capacity	The facility may be undersized for the current collateral base or seasonal peak.	Can a replacement facility be sized around supportable peak and trough collateral, not only today’s balance?
Borrowing base is fully utilized; commitment has room	Eligibility, advance rates, reserves, or collateral levels—not the commitment—are limiting liquidity.	What will a new lender count differently, if anything, after independent diligence?
Availability is negative or near a trigger	The company may be facing a borrowing-base deficiency, restricted draws, or intensified monitoring.	What does the current agreement require, and what liquidity is needed while the process runs?

A simplified availability calculation is:

Eligible collateral × advance rates − reserves − letters of credit − outstanding revolver loans = unused availability.

The arithmetic is simple; the inputs are not. An AR aging can change with one customer payment delay. An inventory reserve can change after a field exam, appraisal, or slow-moving review. A letter of credit may use capacity without producing cash. DCE’s commitment-versus-availability guide explains why the commitment on the term sheet is not the same as money a borrower can draw on a particular day.

Why a Fully Drawn Refinance Requires a Different Package

A replacement lender needs to see two stories at once. First, it needs the ordinary underwriting story: eligible collateral, financial performance, customer and vendor dynamics, reporting quality, and the requested structure. Second, it needs the transition story: how the existing lender will be paid, how the business remains liquid before closing, and whether the requested facility can support operations on day one without relying on an unsupported assumption.

A generic refinancing presentation can obscure the key issue. If the current balance is $12 million and the requested facility is $18 million, the relevant question is not simply whether the larger number sounds reasonable. The lender will ask what portion of the $12 million is supported by eligible collateral today, what would be excluded under its own rules, what reserves it expects, and what cash needs occur before the new facility can close.

That is why management should frame the request around an availability bridge. The bridge reconciles a current, source-supported borrowing-base view to the estimated opening availability under a proposed structure. It does not substitute for the lender’s calculation. It gives the lender a transparent starting point and gives management a way to identify the true refinancing gap before it becomes a closing-week surprise.

Build the Availability Bridge Before Calling Replacement Lenders

An availability bridge should use a clear as-of date and preserve the reports behind every material line. It is better to show a conservative, explainable estimate than an aggressive number that cannot survive diligence.

Bridge item	What to show	Why a lender will care
Current facility usage	Revolver loans, letters of credit, protective advances if any, accrued interest, and other payoff items.	The payoff amount and timing determine the minimum funds needed at closing.
Current collateral	AR aging, inventory detail, locations, and the most recent borrowing-base support.	The lender tests what assets are financeable, not merely what is on the balance sheet.
Eligibility adjustments	Aging, dilution, concentration, disputes, related-party balances, inventory condition, consignment, and known reserves.	These items can materially reduce usable opening availability.
Proposed structure assumptions	Illustrative advance rates, sublimits, reserves, L/C usage, and commitment amount—clearly labeled as preliminary.	A lender needs to understand the management case without being asked to adopt it.
Sources and uses	Existing lender payoff, transaction expenses, working-capital need, any cash contribution, and any other proposed source.	It shows whether the opening structure balances and where any shortfall sits.

Use the current lender’s calculation as a reference, but do not assume a new lender will treat the same collateral identically. A new lender may use different aging cutoffs, concentration limits, advance rates, appraisal assumptions, reserve methodology, or cash-management requirements. The borrower-side objective is to identify the swing factors early, not to present an availability estimate as a credit approval.

An illustrative bridge

Assume a company has $14.0 million of current revolver loans and $1.0 million of outstanding letters of credit. Management’s preliminary view of a replacement facility shows $16.8 million of gross collateral support, less $1.3 million of estimated reserves and L/C usage, for $15.5 million of estimated net borrowing-base capacity. The initial picture suggests $1.5 million of availability after paying the revolver loan, but only after testing the new lender’s eligibility assumptions, closing expenses, and daily operating cash needs.

That is not yet a financing answer. A modest change in an inventory appraisal, a large aged invoice, a concentration cap, or a reserve can erase the apparent cushion. The bridge creates a focused diligence list: Which assumptions are most sensitive? Which reports support them? What happens in the business’s low-availability week? DCE’s ABL advance-rate guide provides additional context for how lender assumptions translate into availability.

Model the Transition, Not Just the Closing Date

Many refinancing models show a clean opening balance on the assumed closing date and stop there. A fully drawn borrower needs a fuller view: the period before close, the first days after close, and the lowest projected availability in the following weeks. The key question is whether the company can meet ordinary operating needs while diligence, documentation, payoff, and cash-management changes are occurring.

Build a weekly liquidity schedule that includes expected customer receipts, payroll, critical vendor payments, inventory purchases, debt-related payments, and facility usage. Tie the schedule to an availability outlook, not cash alone. A company can have expected cash receipts but still face constrained borrowing capacity if collateral is ineligible, a reserve applies, or L/C usage consumes the line.

The 13-week cash flow forecast guide explains how to organize this schedule. For a fully drawn refinancing, pay particular attention to the weeks between the first lender conversation and a possible close. Do not assume a replacement facility will close on a target date or that the outgoing lender must advance additional funds. Show the projected operating need under a base case and a focused downside case, with assumptions that management can explain.

Separate a Refinancing Gap From an Operating Gap

A fully drawn revolver does not automatically mean the business needs a new ABL lender. The constraint may be temporary, structural, or a combination of both. Distinguishing the source of the gap leads to a more credible lender discussion.

• Temporary timing gap. A seasonal inventory purchase, delayed customer receipt, or short transition between banking events may create a short-lived draw need. The lender will still evaluate collateral and cash flow, but the bridge should show when and how the pressure is expected to ease.
• Collateral-recognition gap. The company may be funding assets that the borrowing base does not recognize at the needed time—for example, work in process, pre-receivable purchase commitments, or slow-moving inventory. Increasing the commitment alone does not solve this issue.
• Structural capital gap. The company may need funding for a purpose that does not create near-term eligible collateral, such as an acquisition, a long-lived asset, or a broader balance-sheet repair. A different capital layer or transaction structure may be worth evaluating alongside the revolver.
• Collateral deterioration. Aging, dilution, customer concentration, inventory markdowns, or new reserves may be compressing availability. A replacement lender will examine the cause and whether the change is reversible, recurring, or still developing.

For example, if the revolver is fully drawn because a large order must be funded before it becomes eligible inventory or a receivable, a larger ABL commitment may not be the direct solution. The funding issue exists before the collateral enters the base. DCE’s comparison of purchase-order financing and ABL describes that timing distinction. If the gap reflects persistent debt that exceeds supportable collateral, the analysis should acknowledge that directly rather than masking it with an optimistic opening advance-rate assumption.

Organize Payoff Mechanics Early

A successful refinance requires more than an attractive term sheet. The incoming lender needs a reliable picture of what it must pay at closing, and the outgoing lender’s payoff process may require documents, notices, lien releases, account-control changes, and lead time. Start compiling those items before the final week.

1. Confirm the payoff components. Track principal, accrued interest, fees, letters of credit, cash collateral, protective advances, and any other outstanding obligations separately.
2. Identify cash-management dependencies. Map lockboxes, controlled accounts, deposit-account control agreements, customer remittance instructions, and any transition steps that can affect collection flow.
3. Review existing liens and collateral access. List UCC filings, equipment lenders, landlords, bailees, foreign locations, and other parties with a role in collateral or closing deliverables.
4. Keep the incumbent communication factual. Do not assume an extension, overadvance, waiver, or payoff timing accommodation. Follow the current agreement and obtain appropriate professional advice for its interpretation.
5. Maintain a daily closing bridge. As collections, borrowings, and L/Cs move, refresh the anticipated payoff and opening availability rather than relying on a stale month-end number.

The broader closing workflow is covered in DCE’s ABL closing checklist. The main operational lesson for a fully drawn borrower is simple: a refinance cannot be managed as a one-time balance-sheet event when collateral and cash move every day.

How to Discuss the Situation With Lenders

Lead with a direct, organized explanation. State the current facility balance and maturity or refinancing driver, identify whether the company is constrained by commitment or borrowing-base availability, describe the operating cycle, and provide the current collateral reports and liquidity forecast. Then identify the known pressure points rather than waiting for diligence to expose them.

A lender-ready opening narrative might read: “The company is seeking to refinance an existing working-capital revolver that is currently utilized near the borrowing base during its seasonal purchasing period. The request is supported primarily by domestic commercial receivables and finished-goods inventory. Management has prepared a current availability bridge, a 13-week liquidity forecast, and detail on the customer, inventory, and reserve items that affect the low point.” This framing gives a lender facts to evaluate without claiming that the requested amount is already supported or approved.

Common Mistakes to Avoid

• Equating the old commitment with the new facility size. The incumbent’s commitment is evidence of history, not proof of replacement-lender capacity.
• Presenting gross receivables and inventory as usable collateral. Lenders will examine eligibility, reserves, locations, dilution, concentration, and value—not only balance-sheet totals.
• Assuming a new advance rate solves an unsupported gap. A preliminary lender discussion does not establish final collateral treatment or funding availability.
• Ignoring the low week. A refinance model should be tested against the point of lowest projected availability, not only the closing-date balance.
• Waiting to calculate payoff and cash-management changes. Daily collateral movement can make a stale payoff estimate unhelpful at closing.
• Running a lender process without a coherent use of proceeds. A lender needs to understand the existing payoff, operating need, and any remaining source-and-use gap.

The Bottom Line

Refinancing a fully drawn revolver is primarily a liquidity-and-collateral exercise. Management should show the current borrowing-base reality, the estimated opening structure, the payoff mechanics, and the forecasted low point in one connected package. That work may reveal that a replacement revolver is worth evaluating, that a distinct operating gap needs a separate solution, or that the current facility requires a different immediate conversation.

Either way, the strongest next step is to work from reconciled data and clearly labeled assumptions. That approach helps management identify the real issue before it reaches a lender’s credit committee and makes the lender conversation more efficient without implying any approval, accommodation, or funding outcome.
