Asset based lending

Availability is the only number your borrower reads. It should be the one you can defend.

This is written for the lender: the asset based lending group, the independent finance company, the factor who has grown into revolving collateral facilities. Not for a company looking to borrow against its own assets.

In North America the market calls it asset based lending. In South Africa, where we have customers, it is asset based finance. The argument is identical, and FactorFox serves both with the vocabulary each market actually uses.

Illustration of a borrowing base by collateral class. Per class advance rates, reasoned ineligibles, the age of the evidence behind each class, days to zero on the current trajectory and field exam findings enforced as conditions are the platform’s own behaviour. Borrower name and figures come from a seeded demonstration book.

The monitoring cycle

What actually happens between one certificate and the next.

An ABL facility is not underwritten once. It is underwritten continuously and formalised periodically, and most systems only model the formalising.

  1. Structuring

    Collateral classes, advance rates and the eligibility regime are recorded as rules

    Each class carries its own advance rate, its own eligibility treatment, its own sublimit and its own valuation reference. The rules are recorded with the clause of the loan agreement that imposes them, so the surface enforcing a cap can quote the sentence that created it.

  2. Reporting

    Collateral reports arrive and are held to an evidence standard

    Aging schedules, inventory reports and payable listings arrive by email, portal or SFTP, are extracted under a strict schema and are revalidated in ordinary code before touching the base. A report that does not conform is rejected rather than repaired, because a repaired collateral report is a fabricated one.

  3. Computation

    Ineligibles are applied in an order somebody can argue with

    Aging, cross age, concentration caps, contras, credit balances, disputes, foreign and government obligors, related party sales and retainage each produce a reasoned exclusion rather than a single netted deduction. The borrower sees why, which turns most availability disputes into a short conversation.

  4. Availability

    Availability, reserves and the position against the line, continuously

    Availability compression is reported with days to zero on the current trajectory, so a borrower heading for an overadvance is a conversation this week rather than a decision made under pressure next week. Every figure opens onto the records that produced it.

  5. Examination

    Field exam findings become live conditions, not a filed report

    A lowered advance rate, a new ineligible category, a required follow up or an unresolved reconciliation is honoured by the base and cited to the exam. At the next exam you have a record of what was done about the last one, which is the question examiners tend to open with.

  6. Reporting up

    What you owe your own lender is computed from the same book

    Facility utilisation, concentration, dilution, eligibility movement and the reporting obligations in your own credit agreement are computed continuously and assembled into sealed packets, so signing a compliance certificate is a review rather than an assembly exercise.

Collateral confidence

The base tells you what you may lend. It does not tell you how stale the number is.

Receivable collateral revalues itself every day through payment behaviour. Inventory revalues on a count. Equipment revalues on an appraisal that may be two years old and was performed by somebody who has since retired. Treating those three as equally current, because they all appear as numbers in the same column, is how a base that looks fine becomes a workout that was predictable.

Every class carries the age of its own evidence. The last aging, the last count, the last appraisal, the last exam, each with its date visible next to the value it supports. An input the platform does not hold is named as missing rather than reported as zero, because a missing input and a zero balance are different facts and only one of them is good news.

Behaviour is watched between reports. Payment velocity by obligor, dilution movement against the borrower’s own history, concentration change including exposure under one obligor name across several borrowers, credit limit utilisation and missed promises. These move long before a certificate does, and they are the reason a monthly reporting cadence is not the same thing as monthly monitoring.

Nothing is asserted that cannot be shown. Risk observations are append only at the database level, and where there is no prior observation the platform offers to take a first one rather than inventing a yesterday to compare against.

Confidence and coverage, reported separately

Continuous underwriting reports how confident the conclusion is and how much of the required evidence was actually present, as two different numbers. Blending them produces a single reassuring score that hides which half is weak.

On an ABL book that distinction is the whole game. High confidence on nearly complete evidence is a facility. The same confidence on half the evidence is a facility nobody has looked at since March.

Ineligibles

The categories that decide the number, and the reason attached to each one.

A borrower who disputes availability is almost never disputing the arithmetic. They are disputing a rule nobody showed them.

Ineligible categories and how they are applied
CategoryWhat it removesWhy the reason matters
AgingReceivables past the eligibility period in the agreementThe threshold is quoted from the clause, so a borderline invoice is settled by the document rather than by custom
Cross ageThe whole obligor balance once a stated proportion of it has agedThe most misunderstood exclusion in ABL. Showing the trigger obligor stops the argument in one screen
ConcentrationThe excess above a cap on any single obligor or classComputed under one obligor name across every borrower selling to it, which is where the exposure actually sits
Contras and offsetsAmounts owed back to an obligor that is also a supplierNetting is a legal position, not a courtesy. The offset is named with the payable that creates it
Credit balancesNegative aging buckets that would otherwise inflate the poolSilent inclusion of credit balances is a common source of an availability figure nobody can reproduce
Disputes and deductionsItems flagged as disputed, short paid or under deductionTies directly into dilution measurement, so the same event is not counted twice or missed entirely
Foreign and government obligorsObligors excluded or capped by the agreement absent credit supportSupport instruments are recorded so a covered foreign obligor is not treated as an uncovered one
Retainage and unbilledAmounts not yet billable or held back under contractCritical on construction collateral, where retainage is the difference between an availability figure and a fiction

Why this exists

The facility is monitored by one person, and the file lives in their head.

Every ABL shop has the analyst who knows why that borrower's base looks odd. That knowledge is an operational risk, not an asset.

The base is a workbook with linked tabs, and the only person who can explain the ineligible column is the person who built it.
The computation is the platform's, the rules are recorded with the clause behind them, and any officer can open the exclusion and read the reason.
Between reporting dates the facility is monitored by hoping the borrower calls.
Payment velocity, dilution, concentration and utilisation are measured continuously, and material movement reaches the responsible officer's briefing the morning it happens.
Field exam findings are filed, remembered for a quarter, and gradually stop being honoured by the base.
Findings become conditions the base enforces and cites, so the next exam sees what was actually done rather than what was intended.
Your own compliance certificate is assembled in the last four days of the month from four sources.
The position is already computed and the supporting records are already sealed, so the certificate becomes a review and a signature.
An overadvance is discovered after it exists, and the approval is retrofitted to make the file look right.
An advance above the permitted rate is a gate rather than a warning. It holds, it names the authority required, and the approval is recorded before the money moves.

Around the base

The rest of the ABL operation, on the same records.

Loan and revolver accounting

Advances, paydowns, interest and fee accrual carried continuously across period boundaries, so close is a review rather than a reconstruction.

Collateral monitoring

Obligor payment behaviour, dilution movement, concentration change and credit limit utilisation measured against the borrower's own history rather than a portfolio average.

Covenant reporting

Tests computed continuously with the clause quoted as the evidence and days to breach on the current trajectory. FactorFox standards and contractual covenants are labelled separately, always.

Exception and approval flow

Overadvances, rate exceptions and eligibility waivers approved by named people under four eyes, with the reason recorded in the approver's own words.

Evidence packets

Sealed for the period they describe, with a database trigger refusing mutation. What you knew and when, without a reconstruction exercise.

Briefings for the officer

Six fixed questions answered against the book each person is responsible for, including whether you are within covenant, delivered on the web, in Microsoft Teams or on a phone.

Straight answers

What an ABL credit officer asks first

How often is the borrowing base recomputed?

On every material event, not on a monthly cycle. A borrowing base certificate becomes a moment you sign rather than a moment you calculate, because the position has been maintained continuously since the last one. Each run is versioned immutably, so the availability as it stood on any past date can be opened rather than reconstructed from a backup and an argument.

Our ineligible rules are unusual. Can they be expressed without a developer?

The rule families are configuration: aged receivables, cross age or taint, concentration caps applied per debtor or per class, contras and offsets, foreign and government obligors, credit balances, disputed items, related party sales, unbilled or pre billed amounts and retainage. Each exclusion carries the rule that produced it, so a client arguing about their availability is shown the reason rather than a total. Where a rule needs an input the platform does not hold, it says awaiting a live source and names the source instead of quietly passing.

Does this handle inventory and equipment, or only receivables?

Collateral classes are held separately with their own advance rates, their own eligibility treatment and their own appraisal or valuation reference. What differs by class is the confidence you can place in the number and how quickly it goes stale, so the platform reports confidence and coverage separately rather than blending them into a single figure that implies more certainty than exists. Receivables move daily. An appraisal does not, and the surface says how old it is.

What does the platform do with a field exam?

It holds the findings as conditions rather than as a filed report. An exam that recommends a lower advance rate on one class, adds an ineligible category or sets a follow up date becomes something the borrowing base and the monitoring surface honour, with the exam cited as the evidence. The next exam then has a defensible record of what was done about the last one, which is usually the question the examiner opens with.

We are the borrower on our own facility as well as a lender. Does the platform handle both directions?

Yes, and they are labelled as different categories of obligation everywhere they appear. The tests your borrower owes you are one surface. The covenants you owe your own bank on a rediscount line or a corporate facility are another, and a covenant recorded from your credit agreement is never blended with a modelled FactorFox standard into one compliance score. Breaching a standard is a management problem. Breaching a contract may be an event of default.

Is asset based finance the same thing as asset based lending?

In South Africa and parts of the Commonwealth the market says asset based finance, and in North America it says asset based lending. The mechanics are the same argument about collateral, eligibility and advance rate, though the security instruments and registries differ by jurisdiction. FactorFox serves both, and the terminology on screen follows the market you operate in rather than forcing a North American vocabulary onto a South African book.
