What it means
The security agreement is separate from the loan agreement, though the two are usually signed together. The loan agreement says how much is borrowed and on what terms, while the security agreement says which assets stand behind it and what rights the lender has over them.
Three things make a security agreement effective. It must be properly executed, value must have been given, meaning the loan is actually advanced, and the interest usually must be registered on a public register so that later lenders and buyers are on notice.
Registration is what establishes priority, and a lender that signs the agreement but delays registering can find itself ranking behind someone who registered first. The collateral description is the clause that matters most in practice.
It can be specific, naming a particular machine and its serial number, or general, covering all present and future assets of a category such as stock or receivables. General descriptions give the lender wide protection and correspondingly restrict what the borrower can do without asking.
Beyond the collateral itself, these agreements impose ongoing duties: keep the assets insured, maintain them, do not sell or relocate them without consent, allow inspections, and report on their value periodically. Many borrowers sign without reading these clauses and are surprised when a routine equipment sale becomes an event of default.
The nuance for asset-backed facilities is the borrowing base. Rather than lending a fixed sum, the lender advances a percentage of eligible collateral recalculated monthly, so the available limit rises and falls with the value of the pool the security agreement covers.
In practice
Real-world examples.
Example
A vineyard signs a security agreement giving its bank a charge over bottling equipment, tanks and current stock. The agreement requires annual valuations and forbids selling any listed equipment without written consent.
Example
A staffing agency finances payroll through a facility secured by a security agreement over all present and future receivables. Each week the lender recalculates the borrowing base from the agency's invoice ledger and adjusts the available limit.
Example
A restaurant group takes a $250,000 equipment loan, and the security agreement lists each item of kitchen plant by serial number. When the group later wants to move a combi oven to a second site, it must obtain the lender's consent first.
Formula
Calculation
Borrowing base = Sum of (Eligible collateral category x Advance rate). Collateral coverage ratio = Borrowing base / Loan balance outstanding.
A distributor grants a security agreement over receivables and stock. Eligible receivables under ninety days are $800,000 with an 80% advance rate, contributing $800,000 x 80% = $640,000. Eligible stock is $400,000 with a 50% advance rate, contributing $400,000 x 50% = $200,000. The borrowing base is $640,000 + $200,000 = $840,000, and against a drawn balance of $700,000 the coverage ratio is $840,000 / $700,000 = 1.2. If receivables fell to $600,000, the base would drop to $600,000 x 80% + $200,000 = $680,000, putting the borrower $20,000 over its limit and triggering a mandatory repayment.Case study
Seen in the real world.
Delmore Tooling is a fictional engineering supplier used purely as an illustrative story. It signed a security agreement covering "all present and after-acquired property" in exchange for a $1,100,000 facility, which the owner read as ordinary boilerplate.
Eighteen months later the business wanted a $200,000 equipment loan from a specialist lender to buy a grinding machine. The new lender walked away, because the existing agreement already captured any future asset the business acquired, leaving nothing free to secure the second loan.
The illustrative lesson is that the wording of collateral clauses shapes future options far more than borrowers expect. Delmore eventually negotiated a carve-out permitting purchase money security interests on newly financed equipment, which cost a modest fee and a slightly tighter reporting schedule, and it restored the ability to finance growth without renegotiating the whole facility every time.
Watch out
Common mistakes.
- Treating the security agreement as a formality attached to the loan. It is the document that determines what a lender can seize and what a borrower may do with its own assets, and its terms outlast most negotiations.
- Signing an all-assets clause when a specific asset would do. Broad collateral descriptions block future financing and give a lender leverage over decisions that have nothing to do with the original loan.
- Assuming a signed agreement is enough. Priority normally depends on registering the interest, and an unregistered charge can rank behind a later lender who registered promptly.
Questions
People also ask.
What is the difference between a security agreement and a lien?
The agreement is the contract that creates the lender's interest, while a lien is the resulting legal claim over the property.
Can a security agreement cover assets I do not own yet?
Yes, after-acquired property clauses extend the charge to assets bought later, which is standard for stock and receivables facilities but worth limiting where possible.
What happens to the agreement when the loan is repaid?
The lender should release the charge and file a discharge on the register, and borrowers should confirm that has actually happened rather than assume it.
