The right structure follows the borrower’s balance sheet: collateral-rich to asset-based, cash-generative to cash-flow. The trouble starts when a company is financed the wrong way round.
Key takeaways
- Asset-based lending underwrites collateral; cash flow lending underwrites earnings. That single difference drives sizing, covenants, pricing, and monitoring.
- ABL prices cheaper (roughly 200 to 350bps over the base rate) because of its collateral cushion. Cash flow lending prices dearer (roughly 500 to 650bps) because it relies on earnings.
- The choice follows the balance sheet: collateral-rich and thin-margin points to ABL; cash-generative and asset-light points to cash flow lending.
- The mismatch is where losses concentrate. For an investor, how a manager matches structure to borrower tells you more about the book’s real risk than its headline yield.
Private credit has grown into a core allocation for serious investors and a critical funding source for mid-market companies. Global private debt stood at roughly $1.7 trillion of assets under management in 2024 and is forecast to reach $2.64 trillion by 2029, according to Preqin’s 2025 Global Report. Most of that capital gets lent one of two ways, and the difference between them is where risk and return actually sit.
The two ways are asset-based lending and cash flow lending. One lends against a defined pool of working-capital assets. The other lends against the borrower’s earnings. Both sit under the private credit umbrella, both are usually floating rate, and both are commonly mislabelled as interchangeable. They are not. They underwrite different things, price differently, and behave differently through a downturn.
The right structure is not a matter of taste or negotiation. It follows the borrower’s balance sheet. A collateral-rich, thin-margin business belongs in asset-based lending. A cash-generative, asset-light business belongs in cash flow lending. When a borrower ends up in the wrong one, that mismatch is usually what turns a manageable wobble into a default. What each model underwrites, the numbers that separate them, and a worked example of the same company financed both ways all follow from that.
This is analysis of how the two structures work, not advice on where to put your money.
What each structure actually underwrites
Cash flow lending, often called direct lending in the middle market, is credit underwritten on earnings. The lender’s comfort comes from the borrower’s ability to service debt out of EBITDA and free cash flow, sized against an agreed leverage multiple and protected by covenants and a first-lien claim over the business. The loan is typically a term loan, sometimes a unitranche, that stays outstanding at a fixed amount until it is repaid or refinanced. The borrower is effectively saying: our earnings are the asset.
Asset based lending (ABL) is underwritten on the quality and liquidity of specific collateral, most often trade receivables and inventory, sometimes plant and machinery. The lender does not care nearly as much about the leverage multiple. It cares whether the collateral can be counted, appraised, and sold. Availability flexes with a borrowing base: a live calculation of how much the eligible collateral will support at any given moment. ABL behaves less like a term loan and more like a monitored, collateralised working-capital facility that breathes with the business.
Framed from the borrower’s side, the question is simple. Are you financing earnings, or financing assets in motion?
Why the distinction matters now
Higher base rates have reshaped the economics of both structures, because most private credit is floating rate. When reference rates rose, contracted cash yields moved up with them. The Secured Overnight Financing Rate (SOFR), which underpins many dollar-denominated private credit coupons, sat in the mid-4% range through 2025 before easing toward the high-3% area by mid-2026, per the New York Fed’s SOFR data. Sterling facilities price off SONIA on the same logic. Either way, the base rate feeds straight into the coupon, so the spread the lender charges on top is where the underwriting judgement shows up.
At the same time, banks have pulled back from working-capital and leveraged lending as Basel III and IV capital rules bite, which has handed non-bank lenders room to fill the gap. Apollo puts the global asset-based finance market at around $20 trillion, most of it still on bank balance sheets and steadily migrating out. For anyone assessing managers in the private credit space, this split also stops false comparisons. A cash flow book that lives and dies by EBITDA and covenants is not the same risk as an ABL book driven by borrowing-base quality and collateral liquidation paths. Judging one by the other’s yardstick misreads both.
The two structures, side by side
The cleanest way to see the difference is to lay the mechanics out together. The figures below reflect current mid-market ranges; specific terms move with the borrower’s credit quality and the cycle.
| Asset-based lending | Cash flow lending | |
|---|---|---|
| What is underwritten | Quality and liquidity of specific collateral (receivables, inventory, equipment) | Sustainability of earnings (EBITDA and free cash flow) |
| Sizing basis | Borrowing base: advance rates against eligible collateral | Leverage multiple: a set number of turns of EBITDA |
| Typical capacity | ~80 to 85% of eligible receivables, ~35 to 65% of inventory (OCC handbook) | ~4 to 6x EBITDA for mid-market credits (Capstone Partners) |
| Structure | Revolving facility, availability flexes with the collateral | Term loan or unitranche, fixed amount until repaid |
| Covenants | Light: often a single fixed-charge coverage ratio, springing when liquidity drops below a threshold | Maintenance leverage and coverage covenants, or covenant-lite with springing tests |
| Pricing (spread over base rate) | Lower, reflecting the collateral cushion (roughly SOFR/SONIA + 200 to 350bps) | Higher, reflecting reliance on earnings (SOFR/SONIA + 500 to 650bps) (iCapital) |
| Monitoring | Frequent and mechanical: borrowing-base certificates, ageing reports, inventory appraisals, field exams | Periodic: monthly or quarterly financial reporting, covenant testing |
| Best-fit borrower | Asset-rich, thinner-margin: distribution, manufacturing, retail, seasonal working capital | Cash-generative, asset-light: software, services, sponsor-backed buyouts with stable EBITDA |
Two rows carry most of the weight. The sizing basis is the whole argument in one line: ABL sizes to what the collateral is worth, cash flow lending sizes to what the earnings can service. And the pricing follows directly from it. ABL prices cheaper because the lender holds a defined, saleable collateral cushion, so per the OCC’s own guidance it is treated as a lower-risk structure even when the borrower is weaker. Cash flow lending prices dearer because if earnings fall away, there is often nothing specific to seize.
A worked example: one company, two structures
Take a mid-market distributor. Revenue of £50m, EBITDA of £6m, £12m of eligible trade receivables, and £8m of inventory at cost. It wants to raise debt. What can it borrow under each structure?
Under cash flow lending, the lender sizes to a leverage multiple. At 4.5x EBITDA, a middle-of-the-range figure for a mid-market credit, the company supports roughly £27m of term debt. The lender is underwriting the durability of that £6m of earnings and will set a maintenance leverage covenant, say total debt no higher than 4.5x, plus an interest-cover test. If EBITDA slips to £4m, the same 4.5x cap now supports only £18m, and the existing £27m loan breaches its covenant even though nothing has been drawn down or spent. That is how cash flow deals fail: earnings drift, the covenant tightens around a loan that has not changed, and the refinancing window closes.
Under asset-based lending, the lender ignores the earnings multiple and builds a borrowing base. Advancing 85% against £12m of receivables gives £10.2m. Advancing 50% against £8m of inventory gives £4m. Total availability is about £14.2m, a good deal less than the £27m the cash flow structure offered, and it moves every month with the collateral. If a large customer stops paying and receivables fall to £8m, availability drops to roughly £10.8m automatically. The lender de-risks in real time rather than waiting for a quarterly covenant test.
The same company, the same balance sheet, and the answers are £27m against £14.2m. That gap is the entire point. Cash flow lending offers a strong, cash-generative business more capacity than its assets alone would justify. ABL offers an asset-heavy business steadier access that survives an earnings wobble, at the cost of lending less and watching the collateral far more closely. Neither number is right in the abstract. Each is right for a different borrower.
Which borrower each one suits
Cash flow lending suits predictable earnings
Cash flow structures fit sponsor-backed buyouts, mature service businesses, software with contracted recurring revenue, and industrials with stable end markets. Private credit financed around 85% of 2024 leveraged buyouts, and almost all of that was cash flow lending, because a private equity sponsor buying a profitable business wants to borrow against its earnings, not inventory it into a warehouse.
The model breaks where earnings are lumpy, the sector is structurally declining, or working capital swallows cash unpredictably. Feed one of those into a leverage multiple and the covenant package becomes a tripwire rather than a safety net, exactly as the worked example shows. The business does not need to fail operationally to default; it just needs one soft quarter to breach.
Asset-based lending suits tangible collateral
ABL fits distribution, retail, manufacturing, and any business with a large, appraisable stock of receivables and inventory. It also serves as a rescue structure when a borrower’s EBITDA has weakened to the point where no cash flow lender will size a loan against it, but the balance sheet still holds real, saleable assets. The collateral does the talking when the earnings have gone quiet.
The trade-off is operational. ABL is not set-and-forget. Borrowing-base certificates, ageing reports, dilution analysis, inventory appraisals, and field examinations are the price of the cheaper spread, and a business without the systems to report collateral cleanly will find the facility a genuine burden. The lender is paid for that monitoring work, and the borrower pays in reporting effort.
Where the mismatch bites
The reason this distinction matters to an investor assessing managers, rather than only to a borrower choosing a facility, is that the mismatch is where credit losses concentrate. Put an asset-light software business into ABL and the borrowing base is tiny, because there is almost no inventory or receivables to lend against; the structure starves a perfectly good business of capital. Put a thin-margin, asset-heavy distributor into a cash flow loan and one weak quarter trips a leverage covenant that the underlying collateral could easily have absorbed.
The two structures also fail on different timelines, which matters for how a book behaves in a downturn. Cash flow loans tend to fail slowly: earnings drift, covenants tighten, refinancing windows close over several quarters. ABL can fail fast if collateral quality collapses, but it can also de-risk fast, because the lender shrinks availability as the borrowing base shrinks rather than waiting for a scheduled test. A manager who matches structure to borrower is running a materially different risk profile from one who forces every deal into a single template, and that is visible in the loss numbers over a full cycle.
FAQs
Is asset-based lending safer than cash flow lending?
Not automatically, but it is structured to lose less when a borrower weakens. The lender holds a defined, saleable collateral pool and can shrink availability as that collateral shrinks, which is why ABL prices at a lower spread. Cash flow lending relies on earnings that can evaporate, so it prices higher to compensate. Safer depends on the borrower and the collateral quality, not the label.
Can a company use both at once?
Yes. Some businesses run an ABL revolver for day-to-day working capital alongside a cash flow term loan for longer-term financing, with an intercreditor agreement setting out who has first claim over which assets. Sorting that priority is one of the more negotiated parts of a combined structure.
Why is asset-based lending cheaper if the borrowers are often weaker?
Because the lender is not relying on the borrower’s earnings. It holds specific collateral, monitors it constantly, and can liquidate it if the loan sours. That collateral cushion lowers the loss the lender expects, so the spread comes down, even for a borrower a cash flow lender would decline.
What is a borrowing base?
It is the live calculation of how much an ABL lender will advance at a given moment: eligible receivables and inventory, multiplied by their advance rates, minus reserves. It is recalculated regularly from borrowing-base certificates the borrower submits, so available credit rises and falls with the collateral rather than sitting at a fixed figure.
