What is a Borrowing Base Certificate (BBC)?

Borrowing Base Certificate Defined

A Borrowing Base Certificate (BBC) is a periodic compliance report submitted by a borrower to its lender that certifies the current value of eligible collateral and the maximum amount available for borrowing. In an AR securitization or asset-based lending facility, the BBC is the single most important document because it determines exactly how much liquidity the borrower can access. The certificate is typically signed by an authorized officer of the borrower, attesting to the accuracy of the underlying data and calculations.

Key Fields in a BBC

A standard BBC includes several critical data fields: gross accounts receivable, Sales activity for the period, Collections received, Dilution amounts (credit memos, returns, disputes, shortpays), Writeoffs, an aging breakdown by bucket (Current, 1-30, 31-60, 61-90, 91+ days past due), and a detailed schedule of ineligible receivables by category. The BBC also reports the advance rate applied, reserve amounts by type (dilution reserve, yield reserve, loss reserve, servicing reserve), the net borrowing base, the facility limit, outstanding draws, and the final available amount. Supporting schedules typically include obligor concentration reports, cross-aging summaries, and covenant compliance calculations.

BBC Calculation Flow

The calculation follows a waterfall structure. Start with gross receivables, subtract all ineligible amounts (cross-aged, past-due beyond threshold, concentration excess, intercompany, foreign, disputed), arrive at eligible receivables, apply the advance rate to get the gross borrowing base, then subtract reserves to get the net borrowing base. The available amount is the lesser of the net borrowing base and the facility limit, minus any outstanding draws. Each step must reconcile to the prior period's BBC, with a roll-forward showing new sales, collections, dilution, and writeoffs that explain the change.

Submission Frequency and Reconciliation

Most AR facilities require monthly BBC submissions within 10-15 business days after period-end, though larger or higher-risk facilities may require weekly or daily reporting. The BBC must reconcile to the borrower's general ledger and subledger, and discrepancies must be explained. Material adverse changes, such as a large obligor default or a spike in dilution, can trigger mandatory interim submissions. Automated platforms like Olycor generate BBCs in real time, eliminating manual spreadsheet preparation and reducing the risk of calculation errors or late submissions.

Frequently Asked Questions

How often must a Borrowing Base Certificate be submitted?+

The frequency depends on the facility agreement. Most AR facilities require monthly BBCs, submitted within 10-15 business days after month-end. Larger facilities or those with volatile collateral often require weekly or even daily submissions. A material adverse change in portfolio quality can also trigger a mandatory interim BBC outside the regular schedule.

What happens if the BBC shows an overadvance?+

An overadvance occurs when outstanding draws exceed the net borrowing base. The facility agreement typically requires the borrower to repay the excess within a cure period of 2-5 business days. Persistent overadvances can constitute an event of default, potentially leading to acceleration of the facility and enforcement of collateral rights.

Who is responsible for preparing the BBC?+

The borrower (or its servicer) prepares the BBC, and an authorized officer must sign it, certifying the accuracy of all data and calculations. The lender or its agent then reviews the certificate for compliance. Many facilities also require periodic field audits where the lender independently verifies the underlying receivables data.
