A food manufacturer's loan is secured by a floating charge over its stock and debtors and a fixed charge over its factory.
Purchase Money Security Interest: a Worked Example
The money that bought the asset ranks first on the asset.
BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED · 6 MIN READ
// THE SHORT ANSWER
Purchase money priority is the exception that lets a business buy new assets on finance after it has given a bank security over everything. Whoever funds a specific purchase, if it meets a short registration deadline, can go in front of a bank's prior all-assets security on that asset and its proceeds. Without the exception, a supplier or equipment financier would struggle to lend safely to a company with an all-assets charge. For the bank, it means an all-assets charge ranks behind on what others have financed. The rule is statutory in New Zealand and Australia; the UK reaches a similar result through title.

Every borrower on this site is a composite constructed for teaching, not a client. The market is mid-market commercial lending as practised in New Zealand and Australia; where a convention differs elsewhere, the page says so.

PART OF What Your Bank Holds as Security
// 01 — WHY THE LAW LETS A LATER LENDER JUMP THE QUEUE
The ordinary rule in New Zealand and Australia is that security interests rank by registration, so a lender whose general security agreement covers after-acquired assets would automatically rank ahead on anything the company later bought. A supplier or equipment financier would then be lending behind a charge that existed before its asset did. Purchase money priority answers the fairness point: the bank did not lend against the new machine, and the machine would not be in the company without the money that bought it.
The priority is not limited to banks' competitors. It covers a seller who retains title, a financier whose advance is used to acquire the goods, a lessor under a lease long enough to fall within the Act, and a consignor under a commercial consignment. It is confined to what was financed. Australia's Act gives the status only so far as the interest secures the price or value applied to acquire the asset, and excludes a sale and leaseback, so raising money against an asset the borrower already owns does not qualify there. Refinancing an existing purchase money loan is a different case: Australia's Act keeps the status, while a New Zealand High Court decision in 2007 held that a refinancing could not create a new purchase money interest. An all-monies clause in the same contract ranks in the ordinary way for anything above the price.
// 02 — HOW PRIORITY IS WON OR LOST
The inventory deadline is stricter, because stock turns over and an inventory financier's claim moves to the proceeds. Timing runs from possession, so a financier registers before delivery wherever it can. Australian courts have read possession as possession in the capacity of grantor under the interest, so goods already held under an earlier arrangement need care. Leases need checking in each market: more than one year in New Zealand's definition and, in the usual case, more than two in Australia's.
The UK has no PPSR and no statutory purchase money rule. Hire purchase, leasing and retention of title reach a similar result by keeping ownership with the financier or seller, so the bank's charge does not attach to the asset while that remains so. A UK lender that simply lends the price and takes a charge ranks under the general rules on charges and any priority agreement.
// 03 — THE EXAMPLE
A stone benchtop fabricator in Australia, constructed for this page like every figure in it, gave its bank a general security agreement, registered years ago. It then buys a waterjet cutter for US$1.25m, with US$0.25m of its own cash and US$1.0m from an equipment financier secured on the machine. Later the fabricator fails. The bank is owed US$2.5m and the financier US$0.9m. The machine realises US$0.7m and all other assets US$1.9m, after the claims the law pays first. Figures in US$m.
Three business days past the deadline move US$0.6m from the financier to the bank. On business day 18 the registration is still good, and the financier is still secured, but it has lost the special rank and falls back behind the bank's earlier registration, taking only what is left from the machine. The total recovered is the same in both versions. The financier's shortfall, in the first case, becomes an unsecured claim. In New Zealand the deadline would be 10 working days. The timing and values are the example's.
// 04 — HOW IT DIFFERS FROM THE NEAREST CONCEPTS
A deed of priority reorders security by agreement between the lenders, and can apply to anything. Purchase money priority arises by statute, without the bank's agreement, and applies only to the asset financed and its proceeds. Retention of title is one way of creating such an interest, and in New Zealand and Australia it is usually how a supplier obtains it. A floor plan facility applies the inventory version to a dealer's stock.
Priority and permission are also separate questions. The statute may give the financier first rank, but a negative pledge in the bank's facility can still make the new security a breach, unless it falls within a permitted exception. Many facilities allow purchase money or asset finance up to a stated limit for that reason.

// 05 — WHERE IT DECIDES A FILE
For a bank holding general security, purchase money interests are one reason a charge over the whole company recovers far less than the whole company. The desk looks for them on the register, compares the fixed-asset note with the finance schedule, and values the general security excluding financed assets or including only any surplus above the finance owed. It also repeats the search, because a non-inventory interest can appear after the delivery date without warning. A sudden run of such registrations can suggest that a borrower is financing what it would once have paid for in cash.
For the financier, the file turns on sequence. Confirm whether the goods will be inventory or equipment in this borrower's hands, register against the correct details before delivery, mark the registration properly in Australia, and keep proof of the delivery date. The proceeds also need thought: where a financed asset is sold or insured, the financier's position depends on following the money into a bank account that may be pledged elsewhere, and a lender that registered first over receivables as original collateral, for new value, can outrank an inventory financier on them.

// QUESTIONS PEOPLE ASK
- What is PMSI super priority?
- It is the informal name for the rule that a properly registered purchase money security interest takes first place, ahead of a bank's prior all-assets security, on the goods it financed and their proceeds. It applies in New Zealand and Australia under their personal property securities Acts. The financier or supplier must meet the registration deadline for that type of goods, and the priority is limited to what was financed. If the deadline is missed, the interest generally ranks by its ordinary registration date.
- How long do you have to register a PMSI?
- It depends on the market and the goods. For goods other than inventory, New Zealand allows 10 working days from possession by the debtor and Australia 15 business days from possession by the grantor. For inventory, both require the interest to be in place when the debtor or grantor obtains possession, so the registration effectively has to come before delivery. In Australia the registration must also state that it is a purchase money interest.
- Does a PMSI need the first lender's consent?
- Not for the priority, which comes from the statute once the conditions are met. Neither New Zealand's Act nor Australia's makes notice to the earlier secured party a condition of it. The contract with the first lender is a separate matter. A negative pledge or a restriction on further borrowing may make the new security or debt a breach of the bank's facility unless it is permitted. A borrower should therefore check the facility letter and, where necessary, ask the bank before signing the equipment finance, even though the financier's ranking does not depend on consent.
- Is a lease a purchase money security interest?
- Often, if it is long enough. New Zealand's Act treats the interest of a lessor under a lease for a term of more than one year as a purchase money security interest. Australia's Act covers the lessor under a PPS lease, usually one for more than two years. Shorter arrangements and occasional lessors can fall outside. Under UK law there is no equivalent category, and a lessor simply remains the owner of the asset.
