Borrowing Base Certificate
Definition
A borrowing base certificate is the periodic statement a borrower submits to its lender reporting the current value of eligible collateral, from which available borrowing capacity is calculated. It is the operational document that keeps an asset-based facility honest between formal reviews: the borrower lists receivables, inventory and any other qualifying collateral, applies the agreed advance rates, deducts ineligibles and reserves, and arrives at the availability figure the lender relies on to permit further drawings. Certificates are typically produced monthly, and more frequently where collateral turns over quickly, so both sides can see availability move in near real time. The certificate is only as good as the figures behind it, which is why lenders reconcile it against ageings and management accounts, and periodically send an examiner to conduct a field examination or collateral audit that tests the reported numbers and estimates liquidation value independently. For IP-backed elements, the intangible is not re-measured every cycle in the way receivables are; instead it is appraised by an independent valuer and revalued at set intervals, commonly annually, with that value feeding the base between revaluations. A UK example: a manufacturer drawing on a receivables and inventory facility with an IP top-up would file a monthly borrowing base certificate, and the lender would compare the declared eligible receivables against the aged debtor report before releasing funds. The certificate matters because it enforces discipline and prevents an overadvance, where drawings exceed what the collateral properly supports. For the borrower it is a live view of covenant headroom and liquidity; for the lender it is the audit trail that ties every advance back to verified, eligible collateral and keeps the facility within its agreed risk envelope.

Concepts that frequently appear alongside Borrowing Base Certificate in practice.
The borrowing base is the amount a lender will make available against a borrower's collateral, calculated as eligible collateral multiplied by its advance rate, less ineligibles and reserves. It is the central mechanic of asset-based lending: rather than fixing a loan amount up front, the facility flexes with the value of the underlying assets, so availability rises and falls as receivables, inventory and other collateral change.
An advance rate is the percentage of an asset's assessed value that a lender will actually lend against, converting collateral quality into a realistic borrowing limit. It is the discipline at the heart of advance rate lending: the gap between the asset's value and the amount advanced is the lender's cushion against realisation shortfalls, disposal costs and the time it takes to sell on default.
Collateral ineligibles are items a lender excludes from the borrowing base because they fail its eligibility criteria, so they generate no borrowing availability. In an asset-based facility, availability is calculated by applying an advance rate to eligible collateral, then deducting collateral ineligibles and any reserves.
An asset-based lending reserve is an amount a lender withholds from the borrowing base to cover specific risks or contingencies, reducing the funds a borrower can draw. In an asset-based facility, availability is built up as eligible collateral multiplied by an advance rate, less collateral ineligibles, less reserves.
A field examination is a lender's on-site verification of a borrower's collateral and reported financial figures, carried out before funding and periodically through the life of an asset-based facility. Field examination lending practice exists because availability in an asset-based facility depends on the accuracy of the numbers a borrower reports, and a lender will not simply take those figures on trust.
An overadvance is a drawing that exceeds the amount the borrowing base would normally support, so the borrower is advanced more than the eligible collateral, at applicable advance rates and net of ineligibles and reserves, would justify. In asset-based lending, availability is calculated from the collateral, and an overadvance temporarily breaks that link.
Covenant headroom is the margin between a borrower's actual financial performance and the minimum (or maximum) levels its loan covenants require, measured at each testing date. In IP-backed and asset-based facilities, covenant headroom shows how much a metric such as the debt service coverage ratio (DSCR) or loan-to-value can deteriorate before a covenant breach is triggered.
A collateral audit is an independent examination that tests whether the assets a borrower pledges as security genuinely exist, are properly owned, and can be realised for the value claimed. It underpins asset-based lending, where the amount a borrower can draw depends on the reliability of reported collateral.
