How does a warehouse borrowing base work?

The borrowing base calculates the maximum amount the originator can draw based on the eligible collateral in the warehouse. Each asset is assessed against eligibility criteria, then an advance rate (typically 70-90%) is applied to determine available funding. Concentration limits and reserves further constrain the available amount.

What is the difference between a warehouse facility and a term securitization?

A warehouse facility is a revolving, short-term funding vehicle used during the asset accumulation phase, typically provided by a single lender. A term securitization is a longer-duration, fully funded structure that issues rated tranches to multiple investors. Warehouses are the bridge to term deals.

What are the main risks in warehouse lending?

Key risks include mark-to-market risk (asset values declining below advance rates), concentration risk (over-exposure to a single borrower or sector), performance deterioration triggering covenant breaches, and the risk that the originator cannot execute a term take-out, leaving assets stranded in the warehouse.

Warehouse Facilities | Bridge Financing for Specialty Finance

Warehouse facilities are the bridge between asset origination and term financing. They provide the working capital that enables lenders to scale, accumulating assets until a portfolio is large enough for securitization or term take-out.

Think of it as a staging area: assets are “stored” in the facility until they're ready for “shipment” to term investors—decoupling origination pace from capital markets timing.

What is a Warehouse Facility?

A warehouse facility is a short-term, revolving credit facility that provides funding for asset originators to accumulate loans before permanent financing. A consumer lender might originate 50 loans per day but need 5,000 for an efficient securitization—the warehouse provides capital to accumulate those loans over months.

Key Benefits

Capital Efficiency

Originators don't fund all loans from equity

Scalability

Volume grows faster than balance sheet

Market Flexibility

Time securitizations for optimal conditions

Relationship Building

Warehouse lenders become term investors

The Warehouse Lifecycle

Warehouse facilities operate in a continuous cycle of funding, accumulation, and paydown. Understanding each phase helps originators plan operations and capital needs.

Facility Setup

Negotiate terms, establish SPV (if required), complete documentation and legal opinions, set up accounts and systems, execute initial closing.

Ramp-Up

Begin transferring loans, draw against borrowing base, establish operational rhythm (daily/weekly funding cycles), track eligibility and concentration.

Steady State

Continuous origination and warehouse funding, collections applied to revolving balance, regular reporting and compliance monitoring.

Term Take-Out

Select assets meeting term criteria, execute securitization or term loan, pay down warehouse with proceeds, restart accumulation cycle.

Structure and Mechanics

Warehouse structures range from simple bilateral arrangements to complex multi-lender structures with SPV isolation. The choice depends on originator credit quality, deal size, and funding strategy.

Basic Structure

Component	Function
Originator/Seller	Creates assets, sells to warehouse
Warehouse SPV	Holds assets, issues notes to lender
Warehouse Lender	Provides funding against collateral
Servicer	Manages assets, processes collections
Backup Servicer	Ready to step in if primary fails
Account Bank	Holds collections and reserve accounts

Cash Flow Mechanics

Funding Request

Originator submits eligible assets for funding

Verification

Lender (or agent) verifies eligibility, calculates advance

Advance

Lender funds purchase price less haircut

Collections

Borrower payments flow to collection account

Application

Collections applied to interest, then principal (revolving)

Re-borrowing

Principal paydowns create new availability

Borrowing Base in Warehouses

Warehouse borrowing bases follow similar principles to ABL facilities but with asset-specific characteristics. The advance rate reflects expected recovery value in a liquidation scenario.

Typical Advance Rates

90-95%

Prime Auto

Strong collateral

80-88%

Subprime Auto

Higher losses

75-85%

Consumer Unsecured

No collateral

Asset Type	Advance	Key Factors
Prime Auto Loans	90-95%	Strong collateral, deep market
Mortgage Loans	92-98%	Real estate collateral, liquid market
Trade Receivables	80-90%	Obligor credit, dilution risk
Consumer Unsecured	75-85%	No collateral, cash flow dependent

Definition

Dynamic Availability

Unlike term facilities, warehouse availability changes continuously. It increases when new eligible assets are transferred and decreases from asset payoffs, eligibility losses, or concentration breaches. Daily or weekly borrowing base calculations are typical.

Eligibility and Concentration

Eligibility criteria define which assets can be financed. Concentration limits ensure diversification. Together, they protect lenders from adverse selection and portfolio risk.

Eligibility Criteria

What Can Be Financed

•Minimum credit score thresholds
•Minimum seasoning (first payment made)
•Complete documentation
•Lien perfected, insurance confirmed
•Current, no 30+ day delinquency
•Approved states/jurisdictions

Concentration Limits

Diversification Requirements

Single obligor: 0.5-2% of pool
Geographic (state): 15-25%
Credit score bands: Varies
Maximum loan size
Industry sector: 10-20%
Vintage limits

Economics and Pricing

Warehouse pricing reflects lender cost of funds, credit risk assessment, and competitive dynamics. All-in costs typically run 4-7% at current rates.

Pricing Components

Interest Rate

SOFR + 150-350 bps

On drawn amounts

Unused Fee

25-50 bps

On undrawn commitment

Upfront Fee

50-150 bps

One-time at closing

Risks and Mitigants

Both lenders and originators face specific risks in warehouse relationships. Understanding mitigants is essential for structuring resilient facilities.

Lender Risks

Protection Through Structure

•Originator default → SPV isolation, backup servicer
•Asset performance → Eligibility, advance rates
•Concentration → Limits, diversification
•Fraud → Verification, audits, reps
•Take-out risk → Term commitment, amortization

Originator Risks

Managing Dependency

Facility termination → Multiple relationships
Interest rate → Caps, hedging, fixed-rate assets
Market closure → Liquidity reserves, backup
Eligibility tightening → Clear docs, amendment rights
Repricing → Long notice periods

Transition to Term Financing

The ultimate goal of most warehouse facilities is term take-out financing. Understanding transition mechanics is critical for planning.

Take-Out Options

Term Securitization

Rated ABS issuance to capital markets

Private Placement

Unrated placement with institutional investors

Whole Loan Sale

Direct sale (often with servicing retained)

Term Loan Conversion

Warehouse converts to amortizing term loan

Pool Selection Criteria

Term Take-Out Requirements

Assets for term financing typically need: 3-6 months seasoning minimum, no delinquency history, complete documentation for rating agencies, tighter concentration limits, and pool statistics within rating model parameters.

Types of Warehouse Facilities

Warehouse structures vary by complexity, lender base, and structural protections. The right choice depends on originator stage and funding strategy.

Bilateral vs Syndicated

Bilateral: Single lender, simpler docs, faster
Syndicated: Multiple lenders, larger capacity

On-Balance vs SPV

On-balance: Direct lending, simpler but less protection
SPV-based: True sale, better isolation

Rated vs Unrated

Rated: Agency review, lower cost, longer setup
Unrated: Faster, more flexible, higher cost

Operational Considerations

Successful warehouse management requires robust operational infrastructure—data systems, cash management, and compliance monitoring.

Operational Burden

The operational burden of warehouse facilities often surprises first-time issuers. Investing in systems and processes upfront pays dividends as facilities scale.

Summary

Warehouse facilities are the essential bridge in asset-based finance, enabling originators to scale without proportional equity investment.
