What it means
Working capital assets are a moving target. A distributor might sell and replace its entire inventory six times a year, and its receivables are collected and rewritten every month, so a security package fixed to a list of items on signing day would be worthless within a quarter.
After-acquired collateral solves this by attaching the lender's claim to categories of assets on a rolling basis. New receivables and new stock join the pool automatically as they are created, and assets that are sold or collected drop out, with the cash proceeds usually captured too.
The practical machinery is the borrowing base certificate. The borrower reports eligible collateral each month, applies the agreed advance rates, and the resulting figure caps how much can be drawn, so lending capacity rises and falls with the collateral pool.
Not all new assets count as eligible. Lenders exclude receivables past a certain age, amounts owed by related parties, slow-moving or obsolete stock and inventory held on consignment, so the eligible collateral figure is always lower than the balance sheet total.
Two nuances matter in a downturn. Falling sales shrink the collateral pool and therefore shrink borrowing capacity exactly when cash is tightest, which is why after-acquired structures can amplify a squeeze.
Insolvency rules also limit how far the lender's claim reaches into assets acquired around the date of a filing, so the pool is not unlimited.
In practice
Real-world examples.
Example
An electronics wholesaler draws on a revolving facility secured on stock and debtors. Every container that clears customs becomes after-acquired collateral on arrival, which lifts the borrowing base and funds the next purchase order.
Example
A construction supplier's borrowing base falls by $900,000 in a quarter because a large customer slipped past 90 days and those receivables became ineligible. Nothing was lost or stolen; the collateral simply stopped qualifying.
Example
An agricultural business signs a facility covering all crops and livestock, present and after-acquired. The following season's harvest becomes collateral as it grows, so the lender's coverage rebuilds each year without new documentation.
Formula
Calculation
Eligible collateral = qualifying assets in each category after exclusions
Borrowing base = sum of (eligible collateral in each category x that category's advance rate)
Worked example. Selby Distribution has a revolving facility secured on receivables at an 80% advance rate and inventory at a 50% advance rate, with an after-acquired clause capturing both categories.
Opening month:
Eligible receivables $3,000,000 x 0.80 = $2,400,000
Eligible inventory $1,500,000 x 0.50 = $750,000
Borrowing base = $2,400,000 + $750,000 = $3,150,000
The following month the company wins a new customer. Its original receivables have largely been collected and replaced by new ones, and it has bought additional stock, all of which becomes after-acquired collateral automatically.
Eligible receivables $3,400,000 x 0.80 = $2,720,000
Eligible inventory $1,600,000 x 0.50 = $800,000
Borrowing base = $2,720,000 + $800,000 = $3,520,000
Borrowing capacity has risen by $3,520,000 - $3,150,000 = $370,000 without any amendment to the loan agreement, because the security automatically followed the new assets.Case study
Seen in the real world.
Thistlewood Trading is an illustrative, entirely fictional importer of household goods running a $4,000,000 revolving facility secured on receivables and inventory, both present and after-acquired. For three years the arrangement worked smoothly, with the borrowing base sitting comfortably above the amount drawn.
Then a major retail customer extended its payment terms from 45 days to 90 days. Receivables of $1,100,000 aged past the eligibility cut-off and dropped out of the pool, cutting the borrowing base by $1,100,000 x 0.80 = $880,000 in a single month. The fictional company was drawn at $3,300,000 against a base that had fallen to $3,050,000, creating an immediate $250,000 over-advance.
Thistlewood negotiated a 60-day cure period, accelerated collections on smaller accounts and moved $400,000 of slow stock through a clearance channel to bring the position back inside the base. Afterwards it began forecasting the borrowing base alongside the cash flow forecast, on the reasoning that in this illustrative structure the collateral pool was as much a liquidity constraint as the bank balance itself.
Watch out
Common mistakes.
- Reading the balance sheet value of stock and debtors as the borrowing base. Exclusions and advance rates typically cut the usable figure by a third or more.
- Assuming new assets need to be pledged individually. Under an after-acquired clause they are captured automatically, which is a convenience for the lender and a restriction for the borrower.
- Forgetting that collateral shrinks with sales. Borrowing capacity contracts in a downturn precisely when the business most needs to draw.
Questions
People also ask.
Does after-acquired collateral include cash proceeds?
Usually yes, because well-drafted security documents capture the proceeds of any collateral that is sold or collected.
How is the collateral pool monitored?
Through a borrowing base certificate, typically monthly, supported by periodic field examinations or independent stock counts.
Can a borrower sell after-acquired collateral?
Yes, sales in the ordinary course of business are permitted, but sales outside that course generally need lender consent or a release.
