Core ABF Structures

Asset-based finance encompasses a broad spectrum of structures, from publicly traded securities to private bilateral agreements. The following definitions establish the foundational vocabulary that underpins the entire ABF ecosystem.

Definition

Asset-Based Finance (ABF)

Financing where repayment is primarily sourced from cash flows generated by a specific pool of financial or real assets, rather than from the general operating cash flows of the borrower. Broader than ABS: includes private bilateral loans, warehouse facilities, forward-flow agreements, SRT structures, and publicly issued securities.
Definition

Asset-Backed Securities (ABS)

Tradeable securities whose cash flows are backed by a pool of financial assets. A specific, publicly traded or 144A subset of ABF — all ABS falls under ABF, but ABF includes non-securitised structures.
Definition

Asset-Based Lending (ABL)

A revolving credit facility secured by a borrowing base of current assets (accounts receivable, inventory) with advances capped by eligible collateral value. Typically bilateral, funded by one or few lenders; collateral pool is corporate rather than consumer/financial.
Definition

Asset-Backed Commercial Paper (ABCP)

Short-term notes (≤397 days) issued by a conduit that holds a diversified pool of financial assets; conduit continuously rolls ABCP to fund longer-dated assets. Creates maturity transformation risk; ABCP conduits are subject to Article 17 ESMA disclosure requirements.
Definition

Warehouse Facility

A revolving credit facility that funds asset origination before the assets are securitised or sold; the warehouse lender holds a first-priority lien on the asset pool. A temporary funding mechanism — not a permanent funding structure.
Definition

Forward Flow Agreement

A contractual commitment by a buyer to purchase specified assets from an originator at pre-agreed prices over a defined period, typically 12–36 months. Differs from a warehouse: the buyer purchases outright (no repo); originator retains no ongoing interest; price discovery is forward-looking.
Definition

Securitisation

The process of pooling financial assets (loans, leases, receivables) into a special purpose vehicle, which issues tranched securities backed by the cash flows from those assets. EU definition (SR 2017/2402 Article 2): a transaction where the credit risk associated with an exposure is tranched.
Definition

Synthetic Securitisation / SRT

A capital relief structure where a bank transfers the credit risk of a reference portfolio via protection instruments (CLN or CDS) without selling the assets. Assets remain on the bank's balance sheet; only the credit risk is transferred; EU-regulated under SR Articles 26a–26e.
ABF (Asset-Based Finance)

Broad Category

  • Includes private bilateral loans, warehouse facilities, forward flows, SRT, and ABS
  • Not all ABF is publicly traded or securitised
  • Repayment from asset cash flows
  • Encompasses the full funding spectrum from bilateral to capital markets
ABS (Asset-Backed Securities)

Specific Tradeable Instrument

  • Publicly issued or 144A placed
  • Tranched and rated by rating agencies
  • Subject to ESMA/SEC disclosure requirements
  • A subset of the ABF universe

SPV and Transaction Parties

Every securitisation and most ABF structures rely on a network of legal entities and transaction parties. Understanding the function and legal status of each participant is essential for analysing structural protections and risk allocation.

Definition

Special Purpose Vehicle (SPV)

A bankruptcy-remote legal entity created solely to hold assets and issue securities or borrow against those assets. Bankruptcy-remoteness is the defining feature — achieved through limited purpose charter, limited recourse provisions, and non-consolidation opinions.
Definition

SSPE (Securitisation Special Purpose Entity)

The EU Securitisation Regulation's specific term for the SPV holding securitised assets. Defined in SR Article 2(2): must not carry out any activity other than securitisation.
Definition

Originator

The entity that originated the assets transferred into the securitisation. Under EU SR Article 6, the originator must retain a ≥5% material net economic interest.
Definition

Orphan SPV

An SPV whose equity is held by a professional trustee in a purpose trust (typically Cayman Islands, Jersey, or Ireland), ensuring it is not owned by or consolidated with the originator.
Definition

Variable Interest Entity (VIE)

Under US GAAP (ASC 810): an entity where the controlling party is determined by economic exposure to variable returns rather than voting rights. If the originator is the primary beneficiary, it must consolidate the SPV despite legal transfer of assets.
Definition

True Sale

A transfer of assets constituting a legal sale (not a secured loan) so that the assets are excluded from the originator's insolvency estate. Requires: intent of parties; no obligation to repurchase at par; no practical control retained; supported by a true sale legal opinion.
SRT (Synthetic)

Credit Risk Transfer Only

  • Assets remain on bank's balance sheet
  • Only credit risk transferred via CLN or CDS
  • Assets still count for LCR/NSFR
  • Originator retains all income
  • EU regulated under Articles 26a-26e
True Sale Securitisation

Legal Asset Transfer

  • Assets legally sold to the SPV
  • Removed from originator's balance sheet (if derecognition criteria met)
  • SPV issues notes backed by transferred assets
  • Originator receives cash proceeds
  • Rating depends on SPV asset quality

Borrowing Base

The borrowing base is the central mechanism controlling credit availability in revolving ABF structures. It dynamically links the amount a borrower can draw to the value of eligible collateral in the pool, providing lenders with real-time credit protection.

Definition

Borrowing Base

The maximum loan amount a borrower may draw under a revolving credit facility, calculated as the sum of eligible collateral values multiplied by applicable advance rates. Distinct from a fixed loan: availability fluctuates as collateral values change; monthly BBC certification is standard.
Definition

Eligible Receivables

Receivables that satisfy contractual eligibility criteria and can be included in the borrowing base. Ineligible receivables (delinquent, government obligors, concentrated, cross-border) are excluded.
Definition

Advance Rate

The percentage of eligible collateral value that lenders will fund against; reflects the expected recovery rate in a stress liquidation scenario. Accounts receivable: 70–85%; inventory: 40–65%; equipment: 60–75%; real property: 50–65%.
Definition

Borrowing Base Certificate (BBC)

A periodic certification (typically monthly) by the borrower confirming the composition and value of the collateral pool. The BBC is the primary operational control document; lenders may field audit the BBC quarterly.
Definition

Concentration Limit

A cap on the proportion of the borrowing base attributable to a single obligor, industry sector, or asset type. Prevents a single default from causing a disproportionate availability reduction; typically 10–25% per obligor.
Definition

Exclusion Event

A trigger that removes an asset or LP commitment from the borrowing base (e.g., delinquency, counterparty downgrade, investor failure to fund). Common in both ABL (receivables aging out) and fund finance (LP sovereign immunity).
Definition

Dilution

The reduction in accounts receivable balances through credits, returns, disputes, and volume discounts — rather than through cash payment. Dilution reserve is an advance rate deduction: if trailing 12-month dilution is 8%, lenders may subtract 8% from the AR advance rate.
Definition

Cash Dominion

A mechanism where all collection account receipts are swept daily to pay down the outstanding revolving balance. Hard (full) cash dominion applies from day one; springing cash dominion activates when excess availability falls below a threshold (typically 10–25% of facility size).

Credit Enhancement

Credit enhancement is the collection of structural mechanisms that protect noteholders from losses in a securitisation. The type, quantity, and priority of credit enhancement directly determines the rating of each tranche.

Definition

Credit Enhancement

Structural mechanisms that improve the credit quality of notes issued by an SPV, protecting noteholders from losses. Can be internal (OC, excess spread, subordination, reserve accounts) or external (letters of credit, guarantees, insurance wraps).
Definition

Over-Collateralisation (OC)

The excess of asset principal over the face value of issued notes; expressed as OC ratio = asset balance / note balance. Example: $110M assets backing $100M notes = 110% OC ratio = 10% OC amount.
Definition

Subordination

The structural seniority ordering of tranches: losses are absorbed by junior notes before reaching senior notes. Also expressed as “credit enhancement level” for the senior tranche.
Definition

Excess Spread

The difference between interest received on the asset pool and interest paid on issued notes plus fees. The first line of defence absorbing losses; captured in the spread account before OC tests apply.
Definition

Reserve Account

A cash account funded at closing that provides a liquidity and credit buffer. Typically sized at 0.5–2% of initial pool balance; replenished from excess spread after other waterfall payments.
Definition

Liquidity Facility

A committed credit line (typically from a bank) that the SPV can draw on to cover timing gaps between asset cash flows and note payment dates. Does not cover credit losses — only liquidity shortfalls.
Definition

Servicer Advances

Payments made by the servicer of delinquent scheduled amounts (typically up to 30–60 days) to maintain cash flow continuity to noteholders. Recoverable from future collections; act as temporary CE preventing interest shortfalls.

Cash Flow Waterfall

The waterfall governs the priority of cash flow distribution in a securitisation. Every payment, test, and trigger is codified in the waterfall, making it the single most important document for understanding value protection and loss allocation in any deal.

Definition

Cash Flow Waterfall

The contractual priority of payment sequence in a securitisation. Standard structure: senior expenses → senior interest → OC test → junior interest → reserve replenishment → equity distributions.
Definition

OC Test (Over-Collateralisation Test)

Formula: OC Ratio = Performing Asset Par / Outstanding Note Balance. Failure redirects excess interest proceeds to repay senior notes (turbo). CLO Class A/B OC test minimum typically 121–128%.
Definition

IC Test (Interest Coverage Test)

Formula: IC Ratio = Available Interest Income / Required Interest Payments. Failure traps cash before equity distributions. Typical CLO IC minimum ~120%.
Definition

Turbo Redemption

Accelerated repayment of senior notes triggered by OC or IC test failure, funded by diverting excess spread. Conditional turbo: applies only while the test is failing. Unconditional turbo: always redirects; common in European CLOs.
Definition

Sequential Pay

A principal waterfall in which all available principal is applied to the most senior outstanding tranche until fully repaid before any proceeds flow to junior tranches. Standard during amortisation and post-trigger periods.
Definition

Pro Rata Pay

A principal waterfall in which principal proceeds are distributed proportionally across all tranches simultaneously. Common during revolving period within parameters; switches to sequential on trigger breach.
Definition

Excess Spread Trap

The capture of excess spread to cure an OC or IC test deficiency. Standard mechanic: trap 50% of remaining interest proceeds (or the exact amount needed to cure, whichever is less) and redirect to senior principal.
Definition

Principal Deficiency Ledger (PDL)

An accounting mechanism recording the running total of principal losses. When a default occurs, it is debited from the PDL; when excess spread cures it, it is credited. Common in RMBS and CLOs.
OC Test

Asset Par vs Note Balance

  • Tests asset par against note balance
  • Formula: Performing Par / Note Balance
  • CLO minimum: 121-128%
  • Failure: turbo — excess spread redirects to senior principal paydown
  • Cures via asset balance growth or senior principal paydown
IC Test

Interest Income vs Interest Payable

  • Tests interest income against interest payable
  • Formula: Available Interest / Required Interest
  • CLO minimum: ~120%
  • Failure: trap excess spread before equity
  • CCC assets apply 7.5% cap in OC numerator at market value

Performance Analytics

Performance analytics are the quantitative tools used to monitor asset pool health, detect early signs of deterioration, and project future cash flows. Lenders, servicers, and investors rely on these metrics to manage risk throughout the life of an ABF structure.

Definition

CPR (Constant Prepayment Rate)

Annualised measure of the percentage of outstanding principal prepaid in excess of scheduled amortisation. Monthly equivalent: SMM = 1 − (1 − CPR)^(1/12). High CPR shortens pool life and compresses investor yield.
Definition

CDR (Constant Default Rate)

Annualised measure of the percentage of outstanding principal defaulting in a given period. CDR × (1 − Recovery Rate) = net loss rate. CDR is a gross measure.
Definition

DPD (Days Past Due)

The number of calendar days since a scheduled payment was due but not received. 30–59 DPD: early delinquency; 60–89 DPD: serious delinquency; 90+ DPD: default in most consumer pools.
Definition

Loss Rate

Net credit losses as a percentage of average pool balance. Gross loss rate = charge-offs / average balance; Net loss rate subtracts recoveries.
Definition

Recovery Rate

The proportion of a defaulted loan balance ultimately collected. Secured consumer auto: 50–65%; unsecured consumer: 5–20%; equipment: 40–60%.
Definition

Vintage Analysis

Performance tracking of loans originated in the same calendar period (month, quarter, year), allowing like-for-like comparison across cohorts. The primary tool for identifying underwriting deterioration.
Definition

Payment Rate (PR)

Collections received ÷ beginning balance. Measures revolving pool health for credit cards and ABCP structures. If PR falls below the minimum payment rate threshold, early amortisation triggers.

SRT and Capital Relief

Significant Risk Transfer is a specialised area of ABF where banks use synthetic structures to achieve regulatory capital relief. The terminology is highly technical and closely linked to CRR3/Basel IV requirements.

Definition

Significant Risk Transfer (SRT)

A securitisation or synthetic structure where a bank transfers a material portion of credit risk of a reference portfolio, satisfying regulatory tests that allow reduction of regulatory capital. EU test: quantitative (RWA ratio) or qualitative; EBA Guidelines (July 2023) govern assessment.
Definition

Credit-Linked Note (CLN)

A funded credit derivative: investor pays cash upfront; issuer pays a coupon; in a credit event, the investor loses principal. Funded structure vs unfunded CDS; CLNs dominate SRT issuance (~85–90%).
Definition

Attachment Point

The loss level in the reference portfolio at which the protection seller (investor) begins to bear losses. EU SRT mezzanine: typically ~1–3% attachment point.
Definition

Detachment Point

The loss level at which the investor's tranche is fully exhausted. EU SRT mezzanine: typically ~7–9% detachment point; losses above fall to the bank's retained position.
Definition

Synthetic Excess Spread (SES)

The portion of excess spread contractually committed by the bank to absorb losses before the first-loss tranche. Must be capitalised as a retained securitisation position under CRR3.
Definition

Output Floor

The CRR3/Basel IV requirement that IRB model-derived RWAs cannot fall below 72.5% of standardised RWAs (phasing 2025–2027). Limits capital relief achievable via internal model-based SRT.
Definition

First-Loss Tranche

The most junior tranche; absorbs losses first. Banks typically retain 0.5–1.5% of portfolio as first-loss in EU SRT. Risk retention requirement (5%) often satisfied by this piece.
Definition

p-factor

Multiplier in the SEC-SA method for retained securitisation positions. p=1.0 for non-STS; p=0.5 for STS. Lower p-factor halves the capital charge — key incentive to obtain STS designation.
Directly-Issued CLN

Dual Credit Risk Exposure

  • Investor exposed to dual credit risk: reference portfolio AND issuing bank
  • If bank defaults, investor loses regardless of reference portfolio performance
  • Cheaper to structure
  • SFTR reporting applies for repo financing
SPV-Issued CLN

Isolated Credit Risk Exposure

  • Investor isolated from bank credit risk via bankruptcy-remote collateral structure
  • SPV holds cash collateral separately
  • Investor only exposed to reference portfolio risk
  • More expensive to structure; preferred by rating-sensitive investors

Fund Finance

Fund finance covers the borrowing arrangements available to private equity, private credit, and infrastructure funds. The collateral structures are unique — secured by LP commitments or portfolio asset values rather than individual financial assets.

Definition

Subscription Credit Facility

Revolving credit facility secured by a fund's rights to call uncalled LP capital commitments. Also called “capital call line” or “sub line”; collateral is LP promises to pay, not assets.
Definition

NAV Facility

Loan secured by the net asset value of a fund's investment portfolio. Distinct from subscription line: secured by existing assets (not future capital); used in later fund lifecycle.
Definition

Hybrid Facility

Fund finance structure combining subscription (uncalled commitments) and NAV (portfolio value) collateral. Flips over the fund lifecycle from sub-line dominant to NAV dominant as capital is deployed.
Definition

Included Investor

An LP rated at or above a specified creditworthiness threshold whose uncalled commitment counts towards the subscription borrowing base at standard advance rates (85–90% for large facilities). Exclusion triggers: sovereign immunity without waiver, side letter set-off rights, failure to fund, downgrade.
Definition

Designated Investor

An LP below the Included Investor threshold (unrated, lower-rated, family office) included in the borrowing base at lower advance rates (50–75%). Inclusion typically requires all-lender consent.
Definition

Coverage Ratio Approach

European fund finance methodology: no per-investor advance rates; instead, eligible LP commitments must cover total fund debt at a minimum 1:1 ratio. Administratively simpler than the US Borrowing Base Approach.
Definition

Continuation Fund

A GP-led secondary vehicle where selected assets from an existing fund are transferred into a new SPV, with LPs offered liquidity (sell) or rollover (invest in new vehicle). Requires independent fairness opinion (ILPA July 2024 guidance).
Definition

DPI (Distribution to Paid-in Capital)

Total distributions to LPs ÷ total capital called. A key fund performance metric improved by NAV-funded distributions — a controversial use case flagged in ILPA guidance.
Subscription Credit Facility

Early Lifecycle: LP Commitment Collateral

  • Secured by uncalled LP commitments
  • Used early in fund lifecycle
  • Advance rate 85-90% (Included LPs)
  • Collateral: LP contractual obligations
  • Early amortisation risk: investment period end
NAV Facility

Late Lifecycle: Portfolio Asset Collateral

  • Secured by fund's portfolio assets (net asset value)
  • Used late in fund lifecycle
  • LTV 10-25% diversified PE
  • Higher risk — depends on portfolio performance
  • Non-bank lenders dominate at 1,100-1,300 bps

Fraud Prevention

Fraud in ABF typically involves misrepresentation of collateral — its existence, quality, or exclusivity. The following terms cover both the fraud typologies and the operational and structural controls used to detect and prevent them.

Definition

Double Pledging

The fraudulent assignment or pledging of the same asset as collateral to two or more separate lenders simultaneously. Most common in commodity finance, accounts receivable, and automotive lending; requires real-time IVA/deduplication to prevent.
Definition

IVA (Inventory Verification Agent)

Independent third party verifying the existence, quantity, condition, and ownership of physical assets used as collateral. Key KPIs: Exception Detection Rate, Duplicate Hit Rate, Turnaround Time, Verification Coverage, Data Latency.
Definition

TPV (Third-Party Verifier)

In EU/UK STS securitisation: an ESMA-registered or FCA-registered independent entity verifying the originator's STS self-certification. ESMA Peer Review (March 2025) found NCAs over-relying on TPV attestations.
Definition

UCC Continuation Statement

A filing extending a UCC-1 financing statement's validity for an additional 5-year period. Must be filed in the 6-month window before the original statement's expiry. Missing continuation = lapsed perfection = assets available to trustee-in-bankruptcy.
Definition

Tape-to-Cash Reconciliation

Operational control matching loan data tape to actual cash collections; identifies synthetic/phantom loans and data manipulation. Should be run at high frequency (daily/weekly) for ABF portfolios.
Definition

Floating Charge

UK-specific security interest over a class of assets that “floats” over the pool as assets cycle in and out, crystallising into a fixed charge on default. Broadly analogous to UCC Article 9 “after-acquired property” clause.
Definition

ICA (Independent Collateral Agent)

A single agent holding and managing collateral identifiers across all facilities with the same originator, providing cross-lender visibility without requiring direct data sharing between funders. An emerging structural response to double-pledging risk.
