Revolving, prefunding, and reinvestment

Most ABF facilities aren’t one-time loans. They’re designed to finance an ongoing origination business. Without revolving mechanics, a warehouse or term ABS deal would simply amortize as borrowers repay — the facility would shrink constantly, and you’d need a new deal every few months. Revolving mechanics let you replace runoff with new assets, keeping the facility at its target size and your business financed continuously.

Three related but distinct concepts:

Revolving period: The window during which you can draw additional funds under a warehouse or reinvest principal in a term deal. During this period, principal collections can be used to fund new assets rather than repay investors.
Prefunding: A specific technique used at closing — you issue notes or draw commitments before the collateral pool is fully assembled, holding the undeployed proceeds in a prefunding account while you originate. The pool ramps up over a defined period.
Reinvestment: In term ABS and CLO structures, the mechanics governing when and how principal collections can be reinvested in new eligible assets during the revolving period.

All three serve the same purpose: keeping capital deployed in earning assets rather than sitting in cash.

How to read it in deal documents

Warehouse facilities

The revolving mechanics are built into the fundamental structure — you can draw and repay throughout the revolving commitment period.

Key provisions to locate:

Commitment Termination Date / Revolving Period End Date: When the revolving commitment expires
Borrowing Base: The formula that caps your draws at any time
Availability Period: The window during which new draws are permitted

Most warehouses have a 12-24 month revolving period, after which they convert to amortizing. Some have evergreen provisions (renewable annually). Know which you have before signing.

Term ABS deals

“Revolving Period” is typically a separate article in the indenture, defining:

Duration of the revolving period
The reinvestment criteria that new assets must meet
The rate of reinvestment (you must replenish at a pace that keeps the pool at target)
What happens when reinvestment criteria can’t be met

After the revolving period ends (typically 18-36 months for consumer ABS), the deal enters a controlled amortization or pass-through period.

Sample language:

“During the Revolving Period, Principal Collections received in any period shall be applied to acquire additional Eligible Receivables satisfying the Eligibility Criteria and Portfolio Criteria set forth herein, to the extent such reinvestment is permissible under the Reinvestment Conditions…”

CLOs

CLO reinvestment periods are typically 3-5 years. During this period, the manager reinvests principal proceeds and trading gains in new eligible loans subject to the reinvestment criteria (portfolio tests, eligibility criteria). If the deal is failing an OC test, reinvestment may be restricted.

Prefunding provisions

Prefunding Period: The window (typically 3-6 months) during which the prefunding account balance can be deployed into new assets
Maximum Prefunding Amount: Caps the share of deal proceeds that can sit in the prefunding account (often 20-25% of the initial note balance)
Prefunding Termination Event: Conditions under which the prefunding period ends early (failure to deploy within the window, originator default, deal-level event of default)

What to negotiate

Revolving period duration

Warehouse: Push for a 24-month revolving period with annual extension options. A 12-month window barely gives you time to originate, stabilize, and execute a permanent financing. If you end up with 12 months, confirm the extension mechanics upfront: what does extension require? Typically: no default, borrowing base compliance, and a fee of 25-50 bps.
Term ABS: Most consumer ABS revolving periods are 18-36 months. Push for 24 months if your origination pace can support it. A longer revolving period means more time before you need to refinance or let the deal amortize.

Reinvestment criteria

Reinvestment criteria define what types of assets you can add to the pool during the revolving period. If the criteria are too tight, you can’t replace runoff fast enough and the facility shrinks.

Common restrictions that cause problems:

Requiring reinvestment assets to meet all eligibility criteria (reasonable) plus weighted average portfolio tests (problematic if your origination mix is shifting)
Prohibiting reinvestment if any deal-level test is failing — even tests not directly affected by the new asset being added
Requiring reinvestment of “at least X% of principal collections within Y days” — creates forced origination pressure that may not match your business rhythm

What to push for:

Reinvestment criteria that match origination eligibility criteria, not stricter
The ability to accumulate principal collections in the collection account for up to 5 business days before reinvestment (reduces forced origination pressure)
If a portfolio test is failing due to legacy assets, not the new assets being added, reinvestment should still be permitted as long as the new asset doesn’t make the test worse. This is the “non-worsening” standard — negotiate for it explicitly.

Ramp-up provisions

If your deal closes before the pool is fully assembled:

Maximum prefunding period: 90-180 days is typical. Push for 180 if you’re originating under $10M/month; 90 days is fine if you’re originating $20M+ monthly.
Prefunding account investment: Ensure the eligible investment list includes money market funds, not just Treasury bills. You need liquidity to fund purchases as they close.
Prefunding shortfall: If you don’t fully deploy the prefunding amount within the window, remaining funds are used to repay notes. This reduces the deal size but eliminates negative carry. Model the worst case — what if you only deploy 70%?

Revolving period termination events

Beyond the scheduled end date, most deals include early termination triggers:

Trigger	Typical Threshold	Negotiating Note
Delinquency rate	>X% for Y consecutive periods	Same calibration logic as triggers
Originator insolvency event	Automatic	Non-negotiable
Borrowing base deficiency	Uncured for >5 days	Negotiate cure period
Performance test failure	Depends on severity	Push for cure period before revolving stops

Key negotiating point: Separate “revolving period terminates” from “deal goes into early amortization.” A revolving termination event should ideally just stop new draws, not trigger acceleration or early amortization immediately. The step-down from revolving to controlled amortization is far less severe than immediate acceleration.

Worked example

Scenario a: warehouse revolving period — origination outpacing draw capacity

Deal parameters:

Parameter	Value
Facility committed	$50M
Current outstanding	$42M
Monthly origination volume	$5M
Monthly principal repayments (CPR 18%)	~$630K/month
Advance rate	80%
Revolving period remaining	18 months

Monthly revolving capacity at current origination pace:

Available to draw = $50M - $42M = $8M available

Principal repayments restore capacity as pool turns over: $630K × (1/80%) = $788K capacity restored per month

At $5M/month origination, drawing at 80% advance rate = $4M/month in new draws. Monthly capacity of $8M available + $788K restored is more than sufficient.

Problem scenario: origination spikes to $9M/month

Need $7.2M in draws.

Month 1: $8M available. Still fine, outstanding rises to $46M.
Month 2: available = $50M - $46M = $4M. Plus $788K restored = $4.8M. Need $7.2M. Shortfall: $2.4M.
Month 3: outstanding reaches $50M. No more draws available without repaying.

Lesson: Model your origination ramp against facility capacity month by month. If origination is growing rapidly, you’ll hit capacity constraints well before the revolving period ends. The solution is either an upsize or a second facility — start those conversations before you hit the constraint.

Scenario b: term ABS prefunding period

Deal parameters:

Parameter	Value
Note proceeds raised	$100M
Note pricing	SOFR + 185 bps (~7.35% total)
Eligible investment yield (prefunding account)	4.85%
Prefunding period	90 days
Target deployment	95% of $100M = $95M
Pool assembled at close	$72M
Prefunded amount at close	$28M

Negative carry calculation:

Day Range	Prefunding Balance	Note Rate	Investment Yield	Daily Drag
Days 1-30	$28M	7.35%	4.85%	$1,918/day
Days 31-60	$14M (half deployed)	7.35%	4.85%	$959/day
Days 61-90	$5M (most deployed)	7.35%	4.85%	$342/day

Illustrative pricing. See pricing disclaimer.

Total negative carry over 90-day prefunding period: ~$95K

At $100M deal size, this is less than 10 bps of annualized cost. Modest. But on a $500M deal, this becomes ~$475K — worth optimizing.

How to minimize prefunding cost:

Originate aggressively in the 60 days before pricing so the pool is largely assembled at close
Negotiate a shorter prefunding period (60 days vs. 90) if you can support it
Maximize eligible investment yield within the permitted investments list
Accept that some negative carry is the cost of closing a deal at the right time

Common pitfalls

Not modeling revolving capacity against origination volume. Many originators draw down a warehouse quickly, then discover they’ve used all available capacity before the revolving period ends. Build a monthly model that shows available draw capacity as a function of current outstanding, projected principal repayments (at your CPR), and projected new originations. Run it forward 12 months and flag when you’ll hit capacity constraints.

Reinvestment criteria that don’t match your actual origination mix. You negotiated a term ABS with eligibility criteria based on your portfolio today. Twelve months later, you’ve launched a new product segment with longer terms or a different borrower profile that doesn’t meet the reinvestment criteria. Your deal starts shrinking because you can’t replace runoff with your new product. Negotiate reinvestment criteria with forward flexibility, or build in an amendment mechanism for adding new product types.

Prefunding period too short for your origination pace. If you’re originating $8M/month and need to fill a $100M pool, you need at least 3.5 months at full pace — but your prefunding period is 90 days. Any delays (seasonal slowdown, underwriting issues, system problems) and you won’t deploy fully. Model your origination pace conservatively and negotiate a period that gives you buffer.

Reinvestment prohibition kicking in at the worst time. Many deals prohibit reinvestment when a portfolio test is failing. If your deal is in mild stress — delinquencies elevated, OC test tight — and a reinvestment condition gets triggered, you can suddenly no longer replenish the pool. The deal starts amortizing exactly when you need the capital most. Negotiate non-worsening reinvestment rights: if the new asset doesn’t make any failing test worse, reinvestment should be permitted.

Assuming the revolving period will be extended automatically. Extensions are not automatic. They require no default, lender consent, and often a fee. If you’ve been running tight on covenants or market conditions have changed, your capital provider may decline. Start the extension conversation 6 months before the revolving period end date, demonstrate strong performance, and come prepared to re-underwrite the facility.
