Revolving Credit Facility (Revolver)
Definition
A revolving credit facility, or revolver, is a committed loan under which a borrower may draw funds, repay them and draw again, in any amount up to the facility's limit, at any time during its term, usually three to five years. It is the working-capital instrument of corporate finance: the company uses it to cover the gap between paying suppliers and collecting from customers, to fund seasonal inventory, and as a standby source of liquidity, and it pays for the option through a commitment fee on the undrawn amount and interest on the drawn amount. A term loan, by contrast, is drawn once and amortizes; a delayed draw term loan can be drawn in pieces but not redrawn. The revolver's capacity, how much of the commitment is actually available after letters of credit, borrowing base limits and covenant headroom, and its utilization, how much is drawn, are two of the first numbers a credit analyst looks at.
Why it matters
The revolver is where a company's liquidity is measured and where its lenders' protection is concentrated. Term loan investors, including the private credit funds and CLOs that hold most leveraged loans, rely on the revolver lenders to police the borrower through the springing covenant and to provide the cash that keeps the company current, and they watch revolver utilization as the cleanest signal of stress. For an investor in a private credit fund, a BDC or a business lending platform, understanding how much of a borrower's revolver is drawn, what its availability is after the borrowing base, and when it matures tells more about the next twelve months than the leverage ratio does.
Common misconceptions
- •A revolver is not free liquidity. The commitment fee is paid whether or not it is drawn, and covenants and borrowing bases can make the committed amount unavailable exactly when it is needed.
- •Undrawn does not mean unused. Letters of credit issued under the facility consume capacity, and a revolver can be fully utilized with little cash borrowed.
- •Repaying the revolver is not deleveraging in the term-loan sense. Revolver balances swing with working capital; the analytical question is the trend in average utilization, not the quarter-end balance.
- •A revolver is not the same as a delayed draw term loan. A DDTL is drawn in tranches during a commitment period and then amortizes like a term loan; it cannot be redrawn once repaid.
Technical details
Worked example: a $100 million revolver over a year
Terms: $100 million commitment, five-year tenor, interest at SOFR plus 2.25 percent on drawn amounts, commitment fee 0.375 percent on undrawn, $10 million letter of credit sublimit, springing maximum first-lien leverage of 6.0x tested when utilization exceeds 35 percent.
Q1: the company draws $40 million to build inventory and has $8 million of letters of credit outstanding. Utilization 48 percent, availability $52 million. Interest on $40 million at about 6.6 percent is $660,000 for the quarter; the commitment fee on $52 million undrawn is about $49,000. Utilization is above 35 percent, so the leverage covenant is tested at quarter-end.
Q2: receivables are collected and $35 million is repaid. Drawn $5 million, LCs $8 million, utilization 13 percent, covenant not tested.
Q4: the company draws $60 million to fund an acquisition ahead of a planned term loan add-on. Utilization 68 percent; covenant tested; if leverage is 6.2x the draw is a default unless the lenders waive it, which is the leverage the springing test was designed to catch.
The terms that define a revolver
Commitment: the maximum aggregate amount; may be reduced (commitment reduction) or increased (accordion or incremental facility) under the agreement.
Tenor: three to five years; revolvers usually mature before the term loans in the same agreement so the revolver lenders are repaid first or extended first.
Pricing: a margin over SOFR (or prime for base-rate draws) on drawn amounts, often stepping with leverage; a commitment fee on undrawn amounts; letter of credit fees at roughly the drawn margin.
Availability: commitment less drawings less letters of credit, subject to any borrowing base (asset-based revolvers) and to conditions precedent for each draw (no default, representations true).
Clean-down: some agreements require the balance to be reduced to zero or a low level for a period each year, proving the revolver funds working capital rather than permanent debt.
Springing covenant: a maintenance covenant tested only above a utilization threshold; the only maintenance test in most covenant-lite structures.
Cash-flow and asset-based revolvers
Cash-flow revolver: sized to the borrower's earnings and part of a syndicated leveraged loan agreement alongside term loans; availability is the commitment less usage, limited by covenants.
Asset-based revolver (ABL): sized to a borrowing base of eligible receivables (typically 85 percent advance) and inventory (50 to 65 percent of cost or 85 percent of net orderly liquidation value), reported monthly or weekly; availability moves with the collateral, and the lender has a first lien on it.
A company with both has an ABL for working capital and a cash-flow facility for everything else, with an intercreditor agreement dividing the collateral.
What revolver behavior tells an investor
Rising average utilization with flat revenue: working capital is absorbing cash, or the company is funding losses.
Draws around interest payment dates or maturities: the company is borrowing to service debt.
A full draw during a market event (March 2020): precautionary, and reversed within quarters at healthy companies; not reversed at stressed ones.
Shrinking availability under an ABL: eligible collateral is falling, often because receivables are aging past the eligibility cut-off, which itself signals customer stress.
An amend-and-extend three years before maturity: normal housekeeping. A failure to extend inside eighteen months: a liquidity problem the market has noticed.
Revolvers in private credit and platform lending
Direct lenders and BDCs commit to revolvers alongside their term loans and hold the undrawn commitment as an unfunded obligation, which is why BDC financials show unfunded commitments as a liquidity item and why a rush of draws in a downturn strains them.
Fund-level revolvers: subscription lines are revolvers secured by investors' uncalled commitments; NAV facilities are revolvers or term loans secured by the fund's assets.
Small business platforms: a marketplace line of credit is a revolver in form, usually uncommitted (the platform may refuse a draw), with the borrowing base being the platform's own model of the business.
Frequently asked questions
- What is a revolver loan?
- A line of credit from a bank or a group of lenders that a company can borrow against, pay back and borrow against again up to an agreed limit for the life of the facility. It works like a credit card for a business, with a committed maximum, a fee for keeping the line open and interest only on what is drawn. Revolvers sit alongside term loans in most leveraged loan agreements and are usually the most senior debt a company has.
- What does drawing the revolver mean for cash flow?
- The company borrows cash it did not have, so operating cash flow does not change but financing cash flow rises and net debt rises by the draw. A draw to fund inventory ahead of a selling season is normal and reverses when receivables are collected; a draw to pay interest, fund losses or shore up cash when a maturity is near is a warning sign. Analysts watch whether a revolver is repaid within a cycle or becomes permanently drawn.
- What is a revolver commitment fee?
- A fee, typically 0.25 to 0.50 percent a year for investment-grade borrowers and 0.375 to 0.75 percent for leveraged ones, charged on the undrawn portion of the commitment. It compensates lenders for reserving capital they may never lend. On a $100 million revolver with $30 million drawn and a 0.50 percent fee, the borrower pays $350,000 a year on the $70 million undrawn plus interest on the $30 million. Some agreements step the fee up or down with leverage.
- What is revolver capacity or availability?
- The amount the borrower could draw right now. It is the commitment less amounts already drawn, less letters of credit issued under the facility, and for asset-based revolvers less any shortfall in the borrowing base; it can also be limited by a covenant that the draw would breach. A company reporting $100 million of revolver commitment and $40 million of availability has $60 million tied up in draws, letters of credit or covenant limits.
- Why do companies extend or refinance their revolvers early?
- Because a revolver inside a year of maturity becomes current debt on the balance sheet, rating agencies and lenders treat it as a liquidity risk, and the borrower loses negotiating leverage the closer it gets to the date. Most companies amend and extend two to three years before maturity, often while extending term loans at the same time, and often when credit markets are open rather than when they need to.
- What is a springing covenant on a revolver?
- A financial covenant, usually a maximum leverage ratio or minimum fixed charge coverage, that is tested only when the revolver is drawn above a threshold, commonly 30 to 40 percent of the commitment, on a quarter-end. Covenant-lite term loans have no maintenance covenants at all, so the springing revolver covenant is often the only ongoing test in the capital structure, and it protects the revolver lenders, who are the ones extending new money.
- What does a fully drawn revolver mean?
- That the company has used all its committed liquidity. It happened across corporate America in March 2020 as companies drew down revolvers to hold cash; in isolation, at other times, it usually means the company cannot fund operations or debt service from cash flow and has exhausted its cheapest source. A fully drawn revolver alongside a springing covenant means the covenant is now being tested.
