The Borrowing Base Formula

Every ABL facility operates on a "borrowing base"—a formula that determines how much you can draw at any given time. The lender assigns advance rates to different asset categories: typically 80-85% of eligible accounts receivable, 50-65% of eligible inventory, and varying percentages for equipment and real estate. As your receivables grow or inventory levels change, your available credit automatically adjusts. This creates a financing structure that naturally scales with your business without requiring new applications or approvals.

What Makes Assets "Eligible"

Not all assets qualify for the borrowing base. For receivables, lenders exclude invoices over 90 days old, amounts owed by affiliated companies, or receivables from customers with credit problems. For inventory, they typically exclude obsolete stock, work-in-progress that can't be easily sold, and consignment goods. Understanding these eligibility criteria matters because your actual borrowing capacity will be lower than your total asset values—sometimes significantly lower if your receivables age or inventory turns slowly.

Ongoing Monitoring and Reporting

ABL comes with more oversight than traditional term loans. Expect to submit monthly or even weekly borrowing base certificates that detail your current asset levels. Lenders conduct periodic field exams—auditors who visit your facility to verify inventory counts and review receivables aging. This monitoring isn't just bureaucratic overhead; it's how the lender ensures the collateral supporting your loan remains intact. Businesses comfortable with this level of transparency find ABL works smoothly; those who resist it find the relationship frustrating.

Accounts Receivable

Receivables are the gold standard for ABL collateral because they convert to cash quickly and predictably. Lenders advance 80-85% of eligible invoices, making receivables-heavy businesses ideal ABL candidates. The key factors are customer creditworthiness, concentration (too much from one customer increases risk), and aging. If you sell to Fortune 500 companies with 30-day payment terms, you'll get better advance rates than if you sell to small businesses that routinely pay in 60-90 days.

Inventory

Inventory financing is more complex because the lender must consider liquidation value, not just book value. Finished goods ready for sale command higher advance rates (50-65%) than raw materials or work-in-progress. Commodity products with established secondary markets—think steel, lumber, or consumer electronics—are easier to finance than custom-manufactured goods or perishables. Fashion inventory, seasonal goods, and technology products that become obsolete quickly present challenges because their value can evaporate before the lender could liquidate them.

Equipment and Machinery

Equipment serves as ABL collateral based on orderly liquidation value—what it would fetch in a reasonable sale, not a fire sale. Standard equipment with active secondary markets (trucks, forklifts, CNC machines) commands advance rates of 50-75% of appraised value. Specialized or custom equipment may receive lower advances or be excluded entirely because finding buyers takes time. Equipment typically supports term loan components within ABL facilities rather than the revolving portion.

Real Estate

Owned real estate can significantly expand your borrowing capacity, typically at 50-65% of appraised value. Commercial properties in desirable locations with multiple potential uses command the best terms. Single-purpose facilities (like a specialized manufacturing plant) receive more conservative treatment because they're harder to sell or repurpose. Real estate components usually carry lower interest rates than the working capital portion of ABL facilities, effectively reducing your blended borrowing cost.

Rapid Growth Outpacing Cash Flow

Growing businesses often face a paradox: success creates cash flow problems. You land a major contract, but you need to purchase materials and pay workers before the customer pays you. Traditional lenders see the cash flow strain and get nervous. ABL lenders see growing receivables and inventory—assets that support larger borrowing capacity. The facility naturally expands as your business grows, providing working capital that keeps pace with success rather than constraining it.

Turnaround Situations

Companies emerging from financial difficulties often find traditional lenders unwilling to extend credit despite improving operations. ABL provides a path forward because the focus is on current asset values, not historical financial performance. If you've stabilized operations and have solid receivables and inventory, ABL can provide the working capital needed to complete the turnaround. Many successful corporate restructurings rely on ABL facilities during the recovery phase.

Seasonal Business Needs

Businesses with significant seasonal variation benefit from ABL's flexibility. A retailer building inventory for holiday season can draw heavily against the credit line, then pay down as inventory converts to receivables and receivables convert to cash. The facility accommodates these natural business cycles without requiring new financing each season. Traditional term loans with fixed payments can strain cash flow during off-peak periods; ABL payments flex with your actual borrowing.

Acquisition Financing

ABL frequently supports business acquisitions, particularly when the target company has strong assets but modest cash flow. The combined entity's asset base supports larger borrowing capacity than either company could access independently. This makes ABL attractive for strategic acquirers looking to consolidate industries or private equity sponsors executing buy-and-build strategies. The key is ensuring the combined assets justify the debt required to complete the transaction.

Interest Rates and Spreads

ABL interest rates typically run 1-3% higher than conventional bank lines of credit, reflecting the additional monitoring and risk management involved. Rates are usually structured as a spread over a base rate (Prime or SOFR), ranging from Prime + 1% for the strongest borrowers to Prime + 4% for more challenging credits. The spread you receive depends on your overall credit profile, asset quality, and the competitive dynamics of your specific deal.

Fees Beyond Interest

ABL facilities carry fees that traditional loans don't: field exam fees (typically $1,000-2,000 per day for auditors), unused line fees (0.25-0.50% on undrawn amounts), and collateral monitoring fees. Upfront costs include commitment fees, legal expenses, and appraisal costs that can total 1-2% of the facility size. These fees add up, so calculate your all-in cost of capital rather than focusing solely on the interest rate when comparing financing options.

When ABL Costs Are Justified

Despite higher costs, ABL often makes economic sense when the alternative is turning down business or paying vendors late. If a $500,000 ABL facility costs $15,000 more annually than a conventional line you can't qualify for, but enables you to accept a contract with $100,000 in profit, the math works clearly in ABL's favor. The relevant comparison isn't ABL versus cheaper financing you can get—it's ABL versus no financing at all.
