In asset-based lending, a company borrows against what its customers owe it and the goods in its warehouse, and the amount it may draw moves with them every day. The loan is safe only while those invoices are real, collectible and still owed. Collateral monitoring is the lender's watch on them between the borrower's own reports and the examiner's visits, so that a slow drift is caught while it is still small.
Written for collateral managers and analysts, portfolio managers, field examiners, chief credit officers and credit risk teams at banks and finance companies, and for the leaders deciding whether to automate the work. It assumes no background in asset-based lending.
Imagine you are the collateral manager in the asset-based lending group of a Chicago bank, keeping watch over 46 borrowers. One of them is Ashford Fastener & Supply, a fastener distributor in Rockford, Illinois, with a $45 million credit line and $33.18 million drawn. Its examiner visited on April 14 and found nothing wrong; the next visit is booked for January 11, 2027.
Every day Ashford's sales journal reaches the bank: each invoice it raised, and each credit that cancelled part of one. Since July the credits to its biggest customer, Tremont Equipment Works, have climbed. On September 17 credits ran at 6.41% of the past 30 days' sales, above the 6.25% ceiling that Ashford's own history sets. Tremont now owes 23.6% of everything Ashford is owed, past the agreement's 20% cap, and it has paid nothing since September 3.
On Friday, October 9, Ashford's finance chief filed his weekly borrowing report, certificate 41. It says the company can still draw $5,187,000. Below $4,500,000, the loan agreement lets the bank take control of Ashford's incoming cash. The certificate's arithmetic is right, and it ties to Ashford's own list of unpaid invoices to the dollar. On Monday, October 12, you recompute it.

Applied the way the loan agreement words them, the rules take Tremont's share above the cap and a second customer's overdue balance out of the base, and add a reserve for the rising credits. Ashford is already below the level that should hand the bank its cash. A daily check would have flagged the drift on September 18: 21 days before certificate 41, and 115 days before the scheduled exam.
Watching each borrower's daily data against its own history catches an overstated base and a missed cash trigger weeks before a report or an exam would.
How asset-based lenders watch collateral over the life of a loan

01 · In plain words
Why an asset-based loan needs watching between reports and exams
Most business loans are judged on profit: can the company earn enough to pay the bank back? An asset-based loan, ABL for short, is judged on what the company owns that turns into cash soon: the invoices its customers have not paid yet, and the goods in its warehouse.
The bank lends a share of those, perhaps 85 cents for every dollar of good invoices and 50 cents for every dollar of stock at cost. The total it will lend on a given day is called the borrowing base. As the company sells, invoices pile up and the base grows; as customers pay, the cash goes to the bank and the loan shrinks.
The arrangement is only as safe as the invoices and stock behind it. An invoice the customer disputes, one already cancelled with a credit note, one more than three months overdue, or one owed by a customer who now accounts for a quarter of all sales: each is worth less than its face value. The loan agreement lists which invoices count. Weekly or monthly the borrower sends an aging, its unpaid invoices listed by customer and by how long each has been owed, and a borrowing base certificate that applies the agreement's rules to them. The Office of the Comptroller of the Currency (OCC), which supervises national banks, puts the job plainly in its booklet's section on establishing the borrowing base: watching the borrowing base also gives early warning that credit is deteriorating.1
Collateral monitoring is all the watching a lender does between the loan's first day and its last. It reads the reports and follows the cash through a lockbox, a bank-controlled address and account where customers pay. It tracks how much of each month's sales is cancelled by credits, how fast customers pay, how much any one customer owes, and how fast stock moves. It sends examiners on site to test the books, hires appraisers to value the stock, keeps the bank's legal claim on the collateral filed and current, and acts when a number crosses a line in the agreement.
The hard part is time. The borrower's report is the borrower's own number, and the examiner's visit tests a sample a few times a year at most. Between the two, a customer can grow past its limit, credits can climb, and collections can slow for months. The OCC's own booklet, in its section on monitoring receivables, calls the work labor-intensive.1
The life of one asset-based loan, in five steps

Step 3 is the subject of this guide. The periodic check of each certificate is a step of its own, with its own guide. The people, companies and figures in the example are fictional.
What surprises people new to collateral monitoring
A certificate can be right and still mislead
Ashford's certificate ties to its own aging to the dollar. It still overstates what the bank should lend, because the rules that matter (the customer cap, the cross-aging rule, the reserve for credits) were applied to last quarter's picture.
The regulator's ABL booklet dates from 2017
The OCC's Asset-Based Lending booklet is Version 1.1, January 2017, with references to reputation risk struck out in March 2025. It already warned, in its section on third-party vendors and automation, that monitoring done by hand is slow and open to human error and fraud.1
Lenders name their own monitoring as the weak point
In the industry body's 2026 fraud survey, 22 of 29 member firms named "less stringent monitoring and controls" as a primary vulnerability.2
No rule sets the exam calendar
Neither the OCC nor the Federal Reserve gives a number of days between field exams. Both describe practice for sound borrowers, often quarterly in the OCC's section on field audits and "usually performed quarterly" in the Fed's manual, and tie the rest to risk.1,3
Four terms used on every page
Borrowing base
Eligible invoices and stock times their advance rates, less reserves. The most the lender will lend on that day.
Dilution
The share of sales cancelled by credits: returns, price allowances, disputes, write-offs. Usually shown as credits divided by sales.
Excess availability
The borrowing base, capped at the line, minus what is already drawn. The cushion the borrower can still draw.
Field exam
An examiner's visit to the borrower's office to test invoices, credits, cash, stock and the records behind the reports.
The six streams of evidence a collateral manager watches, and how often each arrives
In shortMonitoring draws on six streams: the borrower's reports, the daily cash, the sales and credit journals, field exams, appraisals, and the bank's own lien records. They arrive at speeds from daily to yearly. The fast ones show trends; the slow ones prove the records are true. Good monitoring uses each for what it can see.
The OCC's booklet lists what the lender receives (its sections on financial reporting requirements and ABL administration). Borrowing base certificates and supporting reports weekly or monthly, and as often as daily depending on the borrower's risk profile; an aging of receivables by customer name, balance outstanding and current payment status; inventory reports, with the borrower certifying the amount, type and condition of the stock.1 It adds that each day, or less often if the agreement says so, the lender should reset the most it will lend to match eligible receivables and cash receipts.1

Separate hands. The OCC's booklet (ABL administration) asks for a clear separation of duties among the staff who approve credit, control collateral and cash proceeds, run field audits and manage the portfolio.1 The Federal Reserve's manual says the people who audit the borrower "should be independent of the credit function."3 Monitoring that one person both runs and approves invites an exam finding.
03 · The rules and their dates
The texts that govern ABL monitoring, from a 1996 exam manual to the 2026 model guidance
Status as of October 2026
In shortNo statute tells a lender how to monitor collateral. The examiners' texts describe sound practice: the OCC's Asset-Based Lending booklet (Version 1.1, January 2017) and the Federal Reserve's exam manual section on asset-based lending (May 1996). The Uniform Commercial Code decides whose claim on the collateral wins. In 2026 the model risk guidance and the OCC's general lending booklet changed, and new third-party guidance was proposed.
The ABL texts are old; the rules around them changed in 2025 and 2026

Practice, written down. Both examiner texts describe what careful lenders do, and both leave the specific numbers to the loan agreement. The 10% to 20% concentration range, the 5% dilution expectation and the quarterly exam are benchmarks an examiner compares you with. Your agreement's own definitions are what you enforce against the borrower.
04 · The signals
Dilution, days sales outstanding, aging and stock turns: the four measures that move first
In shortFour measures change weeks before a borrowing base looks wrong: the share of sales cancelled by credits, how many days of sales sit unpaid, how much of the aging has slid past due, and how fast stock sells. Each is simple arithmetic. Their value comes from tracking them often and against the borrower's own past.
Dilution: sales that never become cash
Dilution = non-cash credits (returns, allowances, price adjustments, disputes, write-offs) ÷ gross sales, over a trailing period
The OCC's section on dilution: returns and allowances, disputes, bad debts and other credit offsets create dilution, which varies by industry; the booklet expects it usually to stay at 5 percent or less of receivables. It asks lenders to analyze trends and significant changes in dilution rates with care, and field auditors to review and test selected credit memos, because a rise can point to falling product or service quality.1 The Federal Reserve's manual says the same in one line: "A lender must know how dilution is occurring in each receivable portfolio to measure it continually."3
In the example, Ashford's credits ran at about 3% of sales from January to June. After a price program for its biggest customer started on June 2, they rose to 4.6% in July, 5.9% in August and 6.9% in September. The three-month average, 5.8%, compares with 3.1% in the three months before the April exam.

A reason code turns a percentage into a question with an owner. Returns and freight claims at their usual level are the cost of doing business. Price credits that appear after the goods shipped, on invoices still counted as collateral, mean the aging overstated what the customer would pay.
Days sales outstanding and collections
DSO = receivables ÷ average daily credit sales · Collections ratio = cash received ÷ sales, over the same window
The OCC frames the same idea as turnover, in its section on borrower analysis: receivable turnover is sales divided by average accounts receivable, receivable days are 365 divided by that turnover, and the lender should look hard at receivable days that rise.1 Among the factors its risk-rating section says lenders and examiners should investigate as they occur is slower inventory turnover or slower collection of receivables.1
Ashford's DSO rose from 47 days at the exam to 58. Its lockbox took in $4.33 million a week over the last six weeks against $5.28 million in the six weeks before, down 18%, while weekly sales held at $4.95 million against $4.90 million. Tremont, which had paid $3.48 million in the earlier six weeks, paid $410,000 in the later six, and nothing after September 3.

Past 90 days, the share went from 4.1% to 9.8%, $3,764,000 of $38,420,000. Those invoices are already ineligible under the agreement, so they come out of the base by themselves. Their growth still matters: it is the trend that tells you next month's ineligibles, and it often moves before dilution and DSO do.
Stock turns
Inventory turnover = cost of sales ÷ average inventory · Inventory days = 365 ÷ turnover
The OCC's worked example: cost of sales of $150,000 on average inventory of $100,000 is 1.5 turns, or 243 days.1 Its risk-rating section lists inventory that builds up without the sales to support it, and inventory written down again and again, among the warning factors; its section on monitoring inventory warns that a switch between FIFO and LIFO accounting can hide inventory and operating problems.1 A borrowing base that moves from leaning on receivables to leaning on inventory is, the booklet says in its section on inventory, often a sign of financial deterioration and of collection problems to come.1
05 · Concentration and cross-aging
How one customer's share and one customer's late invoices change what a lender will advance
In shortTwo eligibility rules move with the customer mix: the cap on any one customer's share, and cross-aging, which makes all of a customer's invoices ineligible once enough of them are late. Both are defined word by word in the loan agreement, and the wording decides the dollars. The same clause read three common ways can move availability by a million dollars.
Concentration: the single-customer cap
The OCC's section on concentrations: a bank normally treats receivables as concentrated when a single account is 10 percent or more of the total receivables portfolio, and a lender should hold concentrated accounts to no more than 10 percent to 20 percent of the receivables borrowing base, or else lower the advance rate against them; exceptions to the limits should be rare.1 The Federal Reserve's manual calls "no more than 20 percent of the receivables assigned ... from one customer" a common benchmark, and notes some lenders add a dollar cap.3
Ashford's agreement excludes invoices owed by one customer "to the extent the Accounts of that Account Debtor exceed twenty percent (20%) of all Accounts of the Borrower." Tremont's share rose from 14.2% at the April exam to 23.6% on October 9: $9,067,000 of $38,420,000. Twenty percent of all accounts is $7,684,000, so $1,383,000 is over the cap. At an 85% advance rate that is $1,175,550 of borrowing power.
One clause, three readings
Agreements differ on two details: whether the cap is a share of all receivables or only the eligible ones, and whether a customer's past-due invoices come out before the cap is measured. Many agreements take ineligibles "without duplication" so one dollar is never removed twice. Tremont has $1,240,000 more than 90 days old, which the past-due rule already removes. Here is what each reading does to the same borrower on the same day.
How the concentration clause is read decides whether Ashford is under its trigger
Ashford's excess availability on October 12 under three readings of a 20% concentration cap, against the $4,500,000 trigger
Cap at 20% of all receivables, whole excess out (this agreement)$1,383,000 out; $980,354 under the trigger$3.5M
Cap at 20% of eligible receivables$1,077,800 out; $723,376 under$3.8M

The first reading follows the words of Ashford's clause, and it is the one the example uses. The third would leave the borrower $63,726 above the trigger and below the 125% warning band, with no cash control. A collateral team that recomputes availability by hand often settles these questions by habit. Write the reading down, per agreement, and apply it the same way every day.
Cross-aging: when late invoices taint the rest
The Federal Reserve's manual explains the rule with an example: "if a borrower's customer owes payment for ten invoices, of which six are delinquent, all ten would be considered ineligible". It calls 50 percent "standard industry practice" and says lenders may be stricter.3 The OCC describes the same rule in its section on delinquency status, under the name cross-aging.1
Delmar Hydraulics owes Ashford $612,000, and $338,000 of it, 55%, is more than 90 days old. The $338,000 is already out as past due. Under the 50% rule the other $274,000 is ineligible too, which is $232,900 of borrowing power. Certificate 41 left it in.
Once more than half of Delmar's balance is late, the current part leaves the base too

Why measure delinquency from the invoice date. The Fed's manual notes that measuring "from the invoice date prevents a borrower from reducing the volume of ineligible delinquent accounts by giving dated terms (extending payment days)." A borrower that quietly moves a customer from 30-day to 90-day terms keeps old invoices eligible for longer.3 The OCC's section on advance rates and ineligible receivables lists re-aged receivables among the usual ineligibles.1
06 · Control limits
Telling drift from noise: control limits set from each borrower's own history
In shortEvery measure wobbles. A control chart, a method factories have used since the 1920s, draws a center line and limits three standard deviations either side from a stable period, and flags points outside them, or runs of points that lean one way. Applied to each borrower's dilution, DSO, collections and stock turns, it separates the change worth a call from the noise.
A fixed threshold, such as dilution above 5%, treats every borrower alike. A distributor whose credits always run at 3% can double them and stay under 5%; a retailer at 5.5% every month trips an alert it does not deserve. A control chart measures each borrower against itself. NIST's statistical handbook describes the method Walter Shewhart proposed in the 1920s: a center line and limits at k standard deviations, where "Historically, k = 3 has become an accepted standard in industry."11
Upper limit = center + 3σ · Lower limit = center − 3σ, with center and σ (standard deviation) from a stable baseline period

In the example, Ashford's trailing 30-day dilution in the 12 months before its April exam averaged 3.40% with a standard deviation of 0.95 points. The limits are 3.40% ± 2.85 points: 0.55% and 6.25%. On September 17 the measure reached 6.41%, 3.2 standard deviations above center. The cause was in the journal: $512,600 of credits to Tremont in 30 days against $168,400 a month in the year before the exam, three times as much.
Run rules catch the slow climb
A slow drift can stay inside the limits for weeks. The Western Electric rules, listed in the NIST handbook, also flag "2 Out of the Last 3 Points Above +2 Sigma", "4 Out of the Last 5 Points Above +1 Sigma" and "8 Consecutive Points on This Side of Control Line".11 Ashford's dilution set off those rules through late August and early September, before the first point crossed the limit.

That trade-off is a policy choice. A sensible pattern is to let a point past a limit raise an alert, and let the run rules color the chart for the analyst without filling the queue. NIST also warns that the published false-alarm rates assume the baseline is known; limits computed from a short history behave less predictably.11

A clean period. The 12 months before the last satisfactory field exam is a natural choice: an examiner tested the records behind them.
Seasonality handled. A garden supplier's spring is its own baseline; compare like months, or use limits that move with the season.
A rule for silence. A borrower that stops sending its journal has no points to plot. Missing data should raise its own alert, the way a late certificate does.
Versioned limits. When a new exam resets the baseline, keep the old limits with their dates, so the next examiner can see what the chart showed at the time.
07 · Field exams and appraisals
Field exams and appraisals: how often they come, what they test, and how to aim them
In shortAn examiner's visit is the one control that tests whether the records are true, and it happens a few times a year at best. Both regulators describe quarterly visits as usual for sound borrowers and more for risky ones. The visit is worth most when it is aimed: at the customers, credits and cash flows the daily data already questions.
The OCC's section on field audits: they are central to monitoring and controlling an ABL loan, and they help catch fraud and financial weakness. The auditor should get written verifications of accounts, physically inspect collateral, examine original invoices, and go through credit memo records with care. Audits come before a new account is booked and regularly after that, often quarterly but more often if the risk calls for it; in a high-risk relationship or a workout, weekly or even daily audits may be right.1 Examiners are told to look closely at an ABL unit that delays audits or stretches audit cycles because it is short of staff.1
The Federal Reserve's manual lists the audit scope: that the certificate "reconciles to the borrower's books", concentrations, trends in receivables, payables, inventory, sales and costs, submitted agings, bank reconciliations, timely tax payments, and compliance with the agreement. It adds direct confirmation with customers "before the initial lending arrangement and periodically thereafter."3

Aiming the exam
A routine exam samples what the examiner chooses on the day. A targeted exam starts from the questions the monitoring has already raised. For Ashford those were specific: verify the Tremont invoices dated after September 1 directly with Tremont's payables team, with proof of delivery; test every September credit memo over $50,000; test Delmar's collections; tie the lockbox to the general ledger. The post-funding checklist from the fraud task force of the Secured Finance Network (SFNet), the industry body for asset-based lenders, asks the same kinds of question: "Is the borrower delaying the field exam or restricting scope?", "Does the cash hitting the bank match the reported collections?"2
Appraisals
For inventory the standard is a net orderly liquidation value, what the stock would fetch in an orderly sale after costs: the OCC's section on collateral appraisals says appraisals should use NOLV as the valuation standard, not cost or retail value. Its section on inventory says lenders typically advance up to 65 percent of the book value of eligible inventory, or 80 percent of the NOLV. Reappraisal should come regularly, in step with the risk, and more often as issues come up.1
Daily data can tell you when to reappraise. In the example's portfolio, a steel service center's coil inventory turned 3.2 times a year against a lower limit of 3.35, with $6.4 million more coil on hand in three months while shipments held; the proposal was to bring its November appraisal forward.
08 · Cash dominion and triggers
Springing cash dominion: the trigger works only if someone measures it correctly
In shortMost asset-based loans route customer payments through a lockbox. Under full dominion the bank applies every dollar to the loan; under springing dominion the cash flows back to the borrower until excess availability falls below a set level. The trigger protects the lender only if availability is measured on the true base, every day.
The OCC describes both in its section on lockbox and cash dominion arrangements. Under full dominion the bank controls the cash collections and applies what the loan needs before it releases any funds; under springing dominion the bank collects the receipts and passes them on to the borrower's account, as long as the borrower keeps to the loan agreement. The bank keeps the right to take control and apply the proceeds if the borrower misses a loan requirement, such as an excess availability standard.1 The lockbox lets the bank watch receivables and cash flows all the time while lowering the risk of borrower fraud.1

Where the trigger level comes from
No regulation sets the level. The OCC's booklet says, in its section on borrower analysis, that for retail borrowers excess availability covenants typically require 10 percent to 15 percent of the borrowing base to stay available, and, in its section on over-advances, that most banks do not allow an over-advance above 10 to 15 percent of the borrowing base.1
The booklet also warns, in its section on covenants, that springing arrangements can weaken the very controls that are the strength of an ABL credit, and asks banks that offer them to set clear policies, which may include standards for how adequate, stable and well preserved liquidity must be.1 Low thresholds for springing cash dominion and springing covenant testing appear in its risk-rating section's list of weaknesses an examiner weighs when rating a credit.1
The trigger is a covenant decision. Springing cash dominion changes how the borrower runs its business overnight. Monitoring should measure the trigger and refer it to the people who own the relationship and the credit. In the example, the cash dominion notice is drafted and held for the portfolio manager and the chief credit officer.
09 · Fraud and other failures
Double-pledged and fictitious collateral: what the 2025 collapses and SFNet's case review show
In shortMost collateral problems are honest drift: a customer that grows too big, credits that creep up, stock that ages. Fraud is rarer and costlier, and two collapses in 2025 led to charges of double-pledged and bogus collateral. Prosecutors' filings and the industry's own review of 26 cases point to the same defenses: independent data, direct verification, and monitoring frequent enough to see patterns.
Two cases in the government's own words
Tricolor · indicted December 2025
Tricolor Holdings, a subprime auto retailer and lender, filed for Chapter 7 on September 10, 2025. The indictment unsealed December 17, 2025 charges its founder and chief operating officer, the U.S. Attorney's release says, with schemes to pledge the same collateral to more than one lender and to alter the details of collateral so that ineligible, near-worthless assets looked as if they met lender requirements. By about August 2025, prosecutors say, Tricolor had pledged about $2.2 billion of collateral against about $1.4 billion of real collateral, and its largest lenders were owed more than $900 million. Its former CFO and a finance executive pleaded guilty.12 The SEC's August 18, 2026 complaint alleges loans were "double pledged" to securitizations and lenders from at least 2020.13 The charges against the others are allegations.
First Brands · indicted January 2026
First Brands Group, an auto parts maker, filed for bankruptcy on September 28, 2025 with about $5 billion of annual sales, $12 million of cash and more than $9 billion of liabilities. The indictment unsealed January 29, 2026 alleges employees "routinely submitted fake invoices, fraudulently inflated invoices, and double-pledged invoices" to factoring partners, and that inventory pledged under off-balance-sheet financing was already subject to its senior lenders' liens. A former executive pleaded guilty on January 26, 2026; the founder and his brother are presumed innocent.14

Banks reported the cost quickly. Fifth Third's 8-K report to the SEC, filed September 9, 2025, disclosed "alleged external fraudulent activity" at a commercial borrower with an asset-backed finance loan of about $200 million, and an expected impairment of $170 million to $200 million.15 In October it reported a $178 million net charge-off tied to Tricolor, and JPMorgan Chase a $170 million charge-off.16

The OCC wrote the same list in 2017, in its section on fraud: a fraudulent borrower can send falsified sales and collection records, pledge the same receivables to more than one bank, divert cash or collateral proceeds, misstate purchase orders, or overstate inventory. Its conclusion: regular collateral monitoring and timely field audits are the best defense against fraud losses.1
Red flags a daily view can see
In the data
Patterns that do not fit
"Manual adjustments to agings", "'Round number' invoices", "Small, same dollar-sized invoices to the same debtor", "A/R aging inconsistent with liquidity condition", "Slowing inventory turnover".2
In the cash
Collections that do not match
SFNet's fix for billing schemes: "Triangulating cash receipts with shipping documents and third-party verified PODs". A post-mortem on the 2025 cases: "Monthly attestations are not sufficient when balances and statuses change daily."2,17
In the liens
Someone else's claim
The OCC's section on collateral liens calls for a lien search before an ABL facility first funds and periodically after that, and says the best answer is for the lender to make sure no other lender holds a lien.1 Under the UCC, competing claims rank by time of filing or perfection.9
Filings lapse. A UCC financing statement "is effective for a period of five years after the date of filing", and "A continuation statement may be filed only within six months before the expiration".8 The OCC's section on lien status monitoring asks for a reminder system for continuations.1 On lapse the lender's security interest becomes unperfected, and it is treated as never perfected against a purchaser of the collateral for value.8
A law firm's review of the 2025 cases warns that "Weak verification processes, overreliance on borrower-provided data, or infrequent audits" let problems go undetected, and that "asset-based lending structures are only as reliable as the controls supporting collateral reporting."18
10 · The market
How big US asset-based lending is, how rarely it loses money, and why lenders now doubt their own monitoring
In shortSFNet, the industry body, sizes US asset-based lending at $537 billion of commitments and $210 billion outstanding. Losses have stayed low for decades, and bank nonaccruals in mid-2026 sat below their 30-year average. The 2025 frauds did not change the averages; they changed what lenders say about their own monitoring.

Quarter by quarter, SFNet's index shows a steady market: in the second quarter of 2026, bank ABL commitments rose 1.3% and outstandings 2.0%; non-bank commitments rose 3.9% while outstandings fell 1.2%; new commitments to new clients rose about 59% at banks and 61% at non-banks.20 In the fourth quarter of 2025 non-bank outstandings rose 12.6%, bank outstandings fell 5.1% on seasonal paydowns, and factors' average days sales outstanding rose 1.3 days to 46.8.21

The same survey found that 67% of respondents saw no change in fraud in their own books while 45% believed it was rising across the industry, and that over three decades losses in the event of default in these asset classes "have averaged less than 50 basis points annually, with fraud representing only a small fraction".2
Credit conditions around the market
Commercial and industrial loans at US banks were about $2.96 trillion in September 2026.22
In the July 2026 Senior Loan Officer Survey, banks left C&I standards "basically unchanged" for firms of all sizes, and significant net shares put standards on loans to nondepository financial institutions, business credit intermediaries among them, at "the tighter ends of their historical ranges since 2011."23
The 2025 review of large shared loans found 8.6% of $6.9 trillion of commitments rated special mention or worse (the examiners' grades for loans with weaknesses), down from 9.1%, "primarily due to growth in new commitments rather than an underlying improvement in credit quality."24
11 · Automation and AI
Arithmetic, rules and AI in a monitoring tool: what SR 26-2 reaches, and which decisions need a named person
Status as of October 2026
In shortThe OCC listed the benefits of automated ABL monitoring in 2017: earlier detection, lower losses from fraud, lower cost, a standard approach. Most of the work, reading files, applying definitions and computing limits, is arithmetic and fixed rules. The April 2026 model guidance leaves those outside its definition of a model and leaves generative AI to each bank's own governance. Decisions stay with named people.
The OCC's booklet follows its warning about manual tracking (section 01), in its section on third-party vendors and automation, by noting that many banks find this kind of monitoring hard and have taken losses because of it. Automated systems, properly put in, bring lower losses from credit risk and fraud, because they help the bank spot problems early, along with lower administrative costs and one standard approach to ABL risk management.1 It adds that the OCC expects banks and their boards to oversee and manage third-party relationships properly.1
SR 26-2, issued April 17, 2026 as one joint guidance by the Federal Reserve, the OCC (Bulletin 2026-13) and the FDIC (FIL-15-2026), superseded SR 11-7.5,10 Its definition of a model excludes simple spreadsheet arithmetic and deterministic rule-based processes, and its attachment puts generative AI and AI that acts on its own outside its scope, leaving their governance to each bank's own framework. The 2023 third-party guidance keeps the responsibility with the bank, and a replacement proposed in September 2026 is open for comment until November 16.4,7

Questions that decide whether automation helps
Does every alert carry its evidence? The report, page and line, or the lockbox file and date, behind each number.
Whose definitions apply? Each agreement's own eligibility clauses, with the reading written down (section 05).
What does it do with silence? A borrower whose files stop arriving should raise its own alert.
Who decides, and how was it tested? Each action should name the person who approved it. NIST's AI framework organizes risk work under GOVERN, MAP, MEASURE and MANAGE; MEASURE here means testing alerts against cases you already know.25
Cause judgments, on-site checks and reserves stay with people
Judgment about causes: a price program can be a sound commercial decision or a cover for disputed invoices.
On-site verification: confirmations, test counts and visits. SFNet's task force puts it as "verify, then fund."2
Reserves, ineligibles above a person's authority, cash dominion, waivers and amendments.
The bank's responsibility for the collateral, which no vendor contract moves.4
12 · How teams monitor today
Today's monitoring routine: five roles, a monthly review per borrower, and the hours spent tying files
In shortA collateral manager reads each borrower's reports, updates availability, checks the agreement's rules and writes up exceptions; a portfolio manager owns the borrower; field examiners and appraisers visit on a schedule; a chief credit officer approves above a limit. Most teams review each borrower in depth once a month, in a spreadsheet, and the hours go to tying files together.
Who watches an asset-based borrower
CM
Collateral manager or analyst
Reads certificates, agings, journals and lockbox reports; updates availability; tracks ineligibles, reserves and late reports; raises exceptions.
Cares about: seeing drift between the monthly reviews.
PM
Portfolio or relationship manager
Owns the borrower: calls, renewals, amendments, covenant conversations.
Cares about: hearing it before the borrower tells them, in dollars of availability.
FE
Field examiner
Tests the books on site: aging to general ledger, confirmations, credit memos, cash, stock counts. The OCC's section on field audits asks for dedicated field audit staff that include skilled accountants.1
Cares about: knowing which three things to test.
LO
Loan operations
Lockbox, loan accounting, advances, UCC ticklers and lien searches.
Cares about: no lapsed filing and no unapplied cash.
CC
Chief credit officer
Approves reserves and actions above the collateral manager's authority, and covenant decisions with the portfolio manager.
Cares about: the trend since the exam, and the proposal.

On that estimate, twelve hours a month across 46 borrowers is about 550 hours every month, the full working time of more than three people, before any exam or appraisal work. Spreadsheets carry most of it, and when the hours run short it is the exam calendar that slips, the pattern section 07 says examiners look for.
In house, outsourced or software: three ways to staff it
In house
Analysts and spreadsheets
Monthly reviews by borrower, with availability kept in a loan system. Flexible and familiar. Weak points: trends assembled by hand, signals in separate files, and a review cadence that sets the detection speed.
Outsourced
Monitoring analysts and field exam firms
Third parties run reviews or exams to the lender's scope. They add capacity; the bank still owns the scope, the decisions and the oversight of the provider.4
Software
ABL platforms and analytics
Borrower portals, automated base calculations and aging comparisons. They differ on how often they read the underlying files, whether they apply each agreement's own wording, and whether trends are judged against each borrower's history.

Botminds ABL Collateral Monitoring on a Monday morning at a fictional Chicago lender
The screens below belong to Bramwell Business Credit, an invented lender with 46 asset-based borrowers and $1.12 billion outstanding. They follow Ashford from the first chart of the day to two signed approvals, then show the rest of the desk. Every company, person, number and document in them is sample data.
13 · One borrower, start to finish
Ashford's morning on screen: a dilution point past its limit, a recomputed base, two approvals
In shortThis is the example from the top of the page, inside the product. Six agents read every borrower's files before the team arrives and chart each one against its own history. Elena Marchetti, the collateral manager, opens on Ashford's dilution chart, re-checks the borrower with the morning's files, reviews the recomputed base and the proposed actions, and approves. Margaret Lindqvist, the chief credit officer, co-approves because the effect is above Elena's $500,000 limit.
1
The chart that opens the morning
By 6:07 am on Monday, October 12, the agents have read 46 lockbox files and 45 daily sales and credit journals and plotted 184 measures: dilution, DSO, collections and stock turns for every borrower. The home screen opens on the one that matters most: Ashford's trailing 30-day dilution against limits of 0.55% to 6.25%, set from the 12 months before its April 14 exam.
Replay since August 12 redraws the chart day by day and stops on September 17: 6.41%, 3.2 standard deviations above center, beyond the limit. The panel on the right lists the credit memos behind the point, Tremont's highlighted: $512,600 in 30 days against $168,400 a month before the exam, three times as much. The record shows the flag on Friday, September 18, Elena's watch the same day, and certificate 41 filed on October 9 with no reserve.
Replay stops on September 17. The first point past the limit, the credit memos that caused it, and what happened next, 21 days before certificate 41 showed it.

Ranked against the last exam, recomputed under the agreement
The watchlist recomputes every borrower under its own credit agreement every morning and ranks the portfolio against each last exam. Ashford tops it at a risk score of 86 with four alerts: $3,778,550 of excess availability recomputed on Friday's aging, against $5,187,000 certified.
Across all 46 borrowers the certificates overstate availability by $3.28 million, $1.41 million of it at Ashford. One borrower is under a trigger.
The watchlist. Each borrower's availability recomputed and as certified, its signals since the last exam, and when the next exam is due.

Re-checked with this morning's files
The September credit memo register arrived at 8:51 am. Elena presses Re-check. The borrower report reader ties 214 memos, $1,482,120, to Ashford's books to the dollar; the lockbox watcher confirms nothing from Tremont since September 3; the eligibility checker applies clause 1.1 of the agreement; the dilution analyst works the reserve.
Recomputed with the register, excess availability is $3,519,646: $980,354 under the $4,500,000 trigger. The four signal cards put each measure beside its value at the exam: Tremont 23.6% against 14.2%, dilution 5.8% against 3.1%, DSO 58 days against 47, past 90 days 9.8% against 4.1%.

The borrowing base screen lays certificate 41 beside the recomputation, line by line: Tremont over the 20% cap, $1,383,000; Delmar cross-aged, $274,000; the dilution reserve of 0.8 point, $258,904. Each adjustment names its clause, and a click opens the agreement's own wording.
Six checks pass: the certificate ties to the October 9 aging, inventory ties to the perpetual report at $19,600,000, no affiliate receivables among 622 customers, the September roll-forward explains the aging within $64,120 (0.17%), insurance names the bank as lender loss payee, and the $350,000 rent reserve covers two leased warehouses.
The base, filed and recomputed. Three adjustments the certificate left out, the gap to the trigger, and the checks that passed.

Six actions proposed, two approvals recorded
The action recommender proposes six actions: take Tremont's excess and Delmar's balance out of the base, take the dilution reserve, bring the field exam forward, ask Ashford for a corrected certificate by Wednesday, October 14, and refer the trigger to Derek Oyelaran, the portfolio manager, and Margaret.
The effect is $1,667,354, above Elena's $500,000 authority. She approves at 9:11 am; Margaret co-approves at 9:12 am. The letter goes to Ray Kowalczyk, Ashford's CFO, and Sam Whitlock, the lead examiner, is booked on site from Monday, October 26 for three days, with tests drawn from the alerts. The cash dominion notice stays drafted and held for Derek and Margaret.
Approved and co-approved. Six actions, the availability effect, two signatures with times, the targeted exam and the letter as sent.
The solution's design targets are at most three days from a change in a borrower's collateral to an alert with its evidence, and every borrower recomputed daily under its own agreement. They are targets, to be measured on your own portfolio. In the sample data, the alert-to-decision median was 1.4 days.
14 · Every screen
The rest of the desk on screen: every borrower's charts, cash and stock drift, the alert log and the clause
In shortThirteen more screens show the rest of the product: the home chart and the whole portfolio as small charts, drift in collections and in stock turns, the borrower before the re-check, receivables, dilution and collections in detail, the proposed actions, the alert log, the settings, a quiet borrower and the clause behind an adjustment.
Collateral control charts. The day's count, 4 beyond a limit, 5 drifting, 170 in control and 5 without data, and the chart that most needs a person. Each run rule can be switched off, and the chart recolors.
Every borrower, every measure. Small charts for dilution, DSO, collections and stock turns, colored where they left their limits, with availability against the trigger and the next exam. A borrower that stopped sending data shows hatched.
Collections drift. Lockbox receipts as a share of sales crossed the lower limit on October 7; the panel shows Tremont's receipts falling from $3.48 million to $0.41 million in six weeks.
Stock turns drift. A steel service center's coil turned 3.31 times on October 4, below its 3.35 lower limit, with $6.4 million more coil on hand in three months; the proposal is an earlier appraisal.
Before the re-check. On Friday's aging alone Ashford is $721,450 under the trigger; the banner says the September register has arrived and is not in the number yet.
Receivables. Tremont's weekly share against the 20% limit, crossing it on October 9; the aging at the exam and now; the top customer with its ineligible amounts.
Dilution. Monthly dilution against the 5% line and September's credits by reason. The note on the right gives the OCC booklet's expectation that dilution usually stays at 5 percent or less.
Collections and the roll-forward. Receipts down 18% while sales hold; opening receivables plus sales, less collections and credits, explain the September aging within 0.17%.
Proposed actions. Each action can be kept or dropped; the panel shows the effect, who approves, and that the exam is not yet booked.
The alert log. Every alert with its measure, when it was raised and how severe, and the median time from a change to an alert and from an alert to a decision.
Your policy as settings. Concentration, cross-aging, past due, the dilution line and reserve rule, collections and DSO alerts and the roll-forward tolerance; each agreement can override them, and changes are versioned.
The clause behind the number. The sample agreement's definition of Eligible Accounts, the fictional lender's and borrower's own contract, opened from the line it governs.
A quiet borrower. An apparel wholesaler $540,000 above its trigger, no open alerts, three measures on watch, and its exam 50 days away.
Select any screen to open it larger. The lender, borrowers, customers, people, agreement text and figures are fictional.
15 · Agents, and who decides
The six agents behind the morning chart, and the three people who approve what they propose
In shortEach agent has one job and limits it does not cross. None of them sets a reserve, moves cash, corrects a borrower's number or triggers a covenant. The collateral manager decides every alert; above $500,000 of availability effect the chief credit officer co-approves; covenant actions stay with the portfolio manager and the chief credit officer. Every decision is logged with its reason.
Six agents read reports, watch cash and score drift
Borrower report reader
Reads certificates, agings, inventory reports, sales and credit journals and credit memo registers as they arrive, and ties the certificate to the aging and the register to the books.
Never corrects the borrower's numbers.
Lockbox and cash watcher
Reads daily lockbox and bank files: receipts by customer, collections against sales, DSO, the monthly roll-forward.
Never moves or applies cash.
Eligibility and concentration checker
Applies each agreement's own definitions: past due, cross-aging, concentration, contras, foreign, affiliates; recomputes the base and availability.
Never changes an agreement's definitions.
Dilution analyst
Computes trailing dilution, sorts credit memos by reason and customer, and works the reserve under the agreement's rule.
Never sets a reserve.
Trend and risk scorer
Plots every borrower's daily measures against limits from its own history, applies the run rules, compares with the last exam, ranks the portfolio and raises alerts.
Never closes an alert or changes a limit.
Action recommender
Proposes reserves, ineligibles, a targeted exam scope and date, the borrower letter and the referral, each with its effect on availability.
Never triggers a covenant or cash dominion.
The collateral manager and chief credit officer who approve each action
DecidesCollateral managerDecides every alert: an action, a watch with a reason, or a dismissal. Approves reserves and ineligibles up to $500,000 of availability effect.
Second approvalChief credit officerCo-approves above $500,000, seeing the trend since the exam and the evidence behind each proposal.
Owns the covenantPortfolio manager and chief credit officerDecide cash dominion, default notices and amendments. The agents refer a trigger; the notice is drafted and held.
Each alert and adjustment opens the report, page and line, the lockbox file or the agreement clause it came from. Thresholds are versioned and a change applies from the next run. Agent steps and human decisions are kept apart on the record, and no letter goes to a borrower before approval.

Part C · Are you ready to automate?
The case for watching every ABL borrower daily: the cost of late drift, the return and readiness
If you run a collateral desk, lead the people who staff one, or answer for the credits it watches, this part helps you decide. It prices late detection, values the analyst time daily monitoring could release, scores your readiness, and lists the questions to put to any monitoring vendor, us included.
17 · What late detection costs
Why a drift seen only at the next exam is expensive, and how to price it on your own book
In shortMost of the cost of slow monitoring sits in a few borrowers: the ones whose base was overstated for months before anyone recomputed it. Published figures frame the risk; your own portfolio gives the numbers that matter. Start with how long a change takes to reach a decision today.

Scoring your collateral desk on borrower files, baselines, agreement readings and governance
In shortPick the answer closest to your desk today. Eight questions score 0 to 2; the last is for reflection. The meter adds up your score as you go, and each question says why it matters and what a strong answer sounds like.
1
Portfolio
How many asset-based borrowers does your desk monitor?
Why it mattersMonthly review hours scale with borrowers; so does the chance that one is drifting unseen.
A strong answer"Forty-odd borrowers, $1 billion outstanding, half on weekly reporting."
2
Data you receive
Do borrowers send agings and credit memo registers electronically, and do you get daily lockbox files?
Why it mattersDaily trends need daily or weekly files. Monthly PDFs limit what any tool can see.
A strong answer"Weekly agings and journals through the portal; lockbox files every morning from treasury."
3
Your baseline
Do you know how long a change in a borrower's collateral takes to reach a decision, and your hours per borrower review?
Why it mattersNo public benchmark exists for either, so your baseline is the only way to prove an improvement.
A strong answer"About five weeks from first sign to reserve on our last ten cases, and ten hours a review."
4
Agreements
Are each agreement's eligibility clauses, reserve rules and triggers written down in one place, with how you read them?
Why it mattersA tool applies the clauses you give it. Section 05 shows one clause read three ways moving availability by a million dollars.
A strong answer"A term sheet per borrower, with our reading of concentration and cross-aging noted by credit."
5
Findings
Have examiners, auditors or loan review commented on your collateral monitoring, exam timing or late reports in the last two years?
Why it mattersFindings bring budgets and deadlines. The OCC tells examiners to watch for exam cycles stretched because a unit is short of staff.1
A strong answer"Loan review found two exams over a year late and one reserve taken two months after the data showed it."
6
Systems
Can software reach your loan servicing system, portal, lockbox files and document store?
Why it mattersFile feeds work; APIs work better. Screens only means a longer setup.
A strong answer"The servicing system has an API; lockbox files land in a folder every morning."
7
Owner and budget
Is there a named owner of collateral monitoring with a budget to change how it is done?
Why it mattersMonitoring crosses collateral, portfolio management, field exams, operations and credit. Without one owner it stalls.
A strong answer"The head of ABL sponsors it with the chief credit officer; budget can move from outsourced reviews."
8
Governance
Do you have a path to approve AI in credit work: vendor due diligence, a view on SR 26-2, approval limits and an audit trail?
Why it mattersThe 2026 model guidance leaves generative AI to your own framework, and third-party guidance keeps the responsibility with you.5,4
A strong answer"Vendor management and model risk have a route for AI tools; every reserve needs a named approver."
9
Vision · for reflection
If an examiner asked tomorrow when you first could have seen your last three reserves coming, what would your files show?
Why it mattersThe gap between the first file that showed the cause and the day you acted is the gap automation closes.
A strong answerA specific answer for each, for example: "the journal showed it on the 17th; we reserved on the 12th of the next month."

Can we replay a year of our own files before we sign?
Yes, scored against what we actually found and when
Demo portfolios only
We found no published independent test of any collateral monitoring vendor's detection speed or false-alarm rate, as of October 2026. A replay of your own files, scored against your own history, is the fairest comparison, and it measures your current process too.
21 · How to start
Starting small: replay a year of files on borrowers you know, then run live beside the desk
In shortPick borrowers whose story you already know, replay a year of their files, and see when each problem would have surfaced. Then run alongside your desk on live files. Decide with three numbers. None of these steps commits you to a vendor.
Date your last ten actions: for each reserve, ineligible or exam finding, the first file that showed the cause and the day you acted.
Choose 10 to 15 borrowers with a year of agings, journals, registers and lockbox files, including the ones behind those actions.
Write down each agreement's readings: concentration base, order of ineligibles, cross-aging percentage, reserve rule, trigger.
Replay, then run in parallel on live files for five weeks, with your collateral manager deciding every alert.
Decide with three numbers: days earlier each known problem surfaced, false alarms per borrower per month, and analyst hours per review.

C2
Which exams ran late in the last two years, and why?
In shortThe questions collateral teams and buyers search for most, each answered on its own.
What is collateral monitoring in asset-based lending?
Collateral monitoring is the lender's ongoing work to keep the receivables and inventory behind an asset-based loan true and sufficient. It covers reading the borrower's reports, following cash through the lockbox, tracking dilution, collections, concentration, aging and stock turns, scheduling field exams and appraisals, keeping liens filed, and acting on triggers. The OCC's booklet (establishing the borrowing base) says borrowing base monitoring gives early warning that credit is deteriorating.
What is dilution in asset-based lending?
Dilution is the share of sales cancelled by non-cash credits such as returns, allowances, price adjustments, disputes and write-offs, usually measured as credits divided by gross sales over a trailing period. The OCC's booklet (its section on dilution) says dilution varies by industry, and expects it usually to stay at 5 percent or less of receivables. Many agreements also take a dilution reserve; the example in this guide takes one point of advance rate for each point of dilution above 5%.
How often should field exams be done for an ABL facility?
No regulation sets a number of days. The OCC's booklet (field audits) describes audits before booking and regularly after that, often quarterly but more often if the risk calls for it, with weekly or daily audits possible in workouts. The Federal Reserve's manual says audits for satisfactory borrowers are "usually performed quarterly." Many lenders set the frequency by risk rating and exposure in their policy.
What is a typical concentration limit for receivables?
The OCC says a single account at 10% or more of receivables is a concentration, and that lenders should limit concentrated accounts to 10% to 20% of the receivables borrowing base or reduce the advance rate against them. The Federal Reserve's manual calls 20% from one customer a common benchmark. The agreement's own wording decides whether the cap is measured on all or eligible receivables.
What is the cross-aging rule?
Cross-aging makes all of a customer's invoices ineligible once a set share of them is past due. The Federal Reserve's manual calls 50% standard practice and gives an example: of ten invoices with six delinquent, all ten become ineligible. Some lenders use a lower percentage.
What is springing cash dominion?
Under springing cash dominion, customer payments flow through a lender-controlled lockbox and are passed back to the borrower until a condition in the loan agreement fails, most often excess availability falling below a set level. From then on the lender applies the cash to the loan. The OCC warns that springing arrangements can weaken the controls that are the strength of an ABL credit, and asks for clear policies on their use.
How is excess availability calculated?
Excess availability is the lesser of the borrowing base and the line, minus loans and letters of credit outstanding. The borrowing base is eligible receivables and inventory times their advance rates, less reserves. For example, a base of $36,699,646 under a $45,000,000 line with $33,180,000 drawn leaves $3,519,646.
What is double-pledging of receivables?
Double-pledging is using the same invoices or loans as collateral with more than one lender. In December 2025 federal prosecutors charged Tricolor's founder with schemes to double-pledge collateral, alleging about $2.2 billion pledged against about $1.4 billion of real collateral; in January 2026 First Brands' founder was charged over allegedly fake, inflated and double-pledged invoices. Lien searches, direct verification with customers and matching cash to reported collections are the usual defenses.
How do lenders detect borrowing base fraud?
Lenders compare the borrower's reports with independent evidence: cash in the lockbox, customer confirmations, shipping documents, lien searches and on-site tests. SFNet's 2026 task force recommends triangulating certificates and invoices against cash receipts and physical counts, and lists red flags such as manual adjustments to agings, round-number invoices and delayed field exams. The OCC's booklet (fraud) calls regular monitoring and timely field audits the best defense against fraud losses.
What is an NOLV appraisal?
A net orderly liquidation value appraisal estimates what inventory or equipment would fetch in an orderly sale, after the costs of selling it. The OCC's booklet (collateral appraisals) says appraisals should use NOLV as the valuation standard, not cost or retail value, and that lenders typically advance up to 80% of the NOLV of eligible inventory. Reappraisal should come more often as issues arise.
What is a control chart, and why use one for collateral?
A control chart plots a measure over time with a center line and limits, usually three standard deviations, set from a stable period. Points outside the limits, or runs of points on one side, flag a change worth investigating. Set from each borrower's own history, it tells a real shift in dilution or collections from normal noise, where a single fixed threshold treats every borrower alike.
Can AI monitor ABL collateral?
Software can read borrower files and lockbox data every day, apply each agreement's eligibility rules, chart trends and draft alerts, exam scopes and letters. Reserves, triggers and covenant actions should stay with named people, with a second approval above a limit. Under the April 2026 model guidance, simple arithmetic and fixed rules fall outside the definition of a model and generative AI is left to each bank's own governance.
How big is the US asset-based lending market?
SFNet's market sizing study, published in February 2026, put US asset-based lending at $537 billion of commitments and $210 billion outstanding at the end of 2024. Its second-quarter 2026 survey showed bank commitments up 1.3% and outstandings up 2.0% on the quarter, with bank non-accruals at 0.78% against a 30-year average of 0.92%.

In shortThe whole guide on one screen: the routine, the rules as of October 2026, the readiness bands and the terms.
The routine
Read every report, journal and lockbox file as it arrives; flag the ones that stop.
Recompute availability under each agreement's own clauses, with your reading written down.
Chart dilution, DSO, collections and stock turns against each borrower's own history.
Compare every measure with the last exam; aim the next exam at what moved.
Measure triggers on the recomputed base; refer them to the people who own them.
Keep liens continued and appraisals current; log every decision with its evidence.
Readiness: score 0–2 on eight questions: 0–6 explore · 7–11 pilot · 12–16 implement.
As of October 2026: OCC Asset-Based Lending booklet Version 1.1 (January 2017; reputation-risk references struck March 2025) · Fed exam manual §2160.1 (May 1996) · SR 26-2 replaced SR 11-7 on April 17, 2026 · OCC lending booklet Version 1.0, July 2026 · third-party guidance replacement proposed, comments due November 16, 2026.
