An ABL facility is quoted as a limit, but what you can actually borrow on any given day is the borrowing base: eligible collateral multiplied by an advance rate, less reserves. Companies are routinely surprised that a $3M facility makes $1.6M available, and the reason is always in the eligibility rules rather than in the headline number.
Advance rates are the easy part and vary less than people expect. Receivables commonly advance in the region of 80 to 85 percent, finished-goods inventory closer to 50 percent of net orderly liquidation value, raw materials lower again, and equipment against appraised forced-liquidation value on a separate amortizing tranche. What moves availability is not the percentage. It is what gets struck out before the percentage is applied.
The figures are illustrative and every lender's eligibility schedule differs, but the shape holds: gross collateral of $8M supporting roughly $3.6M of availability. The gap between those two numbers is the entire negotiation. Advance rates get all the attention in a term sheet discussion and eligibility definitions decide the outcome.
Two lines in that table are worth understanding before you sign anything. Dilution measures the share of invoiced revenue that never converts to cash because of credits, rebates, returns and short-pays; a lender measures it historically and reserves against it, so a business with generous return policies quietly funds a smaller facility. Concentration caps exposure to any single customer, commonly somewhere between 15 and 25 percent of the ledger, and it strikes out only the excess above the cap rather than the whole relationship.
