Shortfall Debt: a Worked Example
The security is sold; the part of the debt it did not cover is not.
BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED
// THE SHORT ANSWER
Shortfall debt is where enforcement turns from selling assets to chasing people. It is measured on the day the last security is realised: the whole debt by then, including interest to that day, default interest and the costs of enforcing, less what the sales actually netted after their own costs and any claims that ranked ahead. That residue no longer has security behind it, so what the lender recovers depends on guarantors, on any other assets the borrower has and on the dividend an insolvency pays. Most arguments about a shortfall are really about how it was produced: the prices achieved and the costs charged.
BASIS Practitioner judgment from sixteen years in commercial banking, set out in How Bankers Think (Highbank Press, 2026). 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.

// 01 — HOW A SHORTFALL IS BUILT
Two things move while a lender enforces, and both move against the borrower. The debt grows: interest runs to the day of settlement, often at a default rate, and the costs of receivers, agents, lawyers and valuers are added if the documents allow it, as they commonly do. The proceeds shrink: assets are sold on the lender's timetable rather than the owner's, selling costs come off the price, and some claims rank ahead of the lender on particular assets, such as employee entitlements paid out of debtors and stock.
Debt at settlement = principal + interest to settlement
+ default interest + enforcement costs
Net proceeds = sale prices − selling costs − claims ranking ahead
Shortfall = debt at settlement − net proceeds of all security
The words "of all security" matter. A lender holding a mortgage, a general security agreement and a third-party mortgage has no shortfall until all three are realised or released, because an all-monies clause usually makes each secure the whole debt.
// 02 — THE EXAMPLE
A swimming-pool builder, constructed for this page like every figure in it, owes its bank a term loan secured by a mortgage over its yard and a general security agreement over the business, plus an overdraft. Its two directors have given a joint guarantee limited to US$1.0m. The bank appoints receivers, who take seven months to sell everything. Figures are in US$m and belong to the example.
Debt at appointment (term 2.40 + overdraft 0.48) 2.88
Interest and default interest during enforcement + 0.17
Receivers' fees and legal costs + 0.21
Debt at final settlement 3.26
Yard: sold 1.95, less selling costs 0.07 1.88
Plant and vehicles: auction 0.41, less costs 0.05 0.36
Debtors: collected 0.29, less employee claims 0.12 0.17
Net proceeds 2.41
Shortfall: 3.26 − 2.41 = 0.85
Of the US$0.85m, US$0.38m was added during enforcement itself, in interest and costs. The rest is the gap between what the assets were lent against and what they fetched once the business had stopped. The directors' guarantee covers the whole of it, within its US$1.0m limit.
// 03 — WHAT HAPPENS TO IT NEXT
The lender has several routes, often used together. It demands payment from the guarantors. It proves in the borrower's liquidation as an unsecured creditor and takes whatever dividend is paid; in England and Wales a secured lender cannot share in the prescribed part for its shortfall. It may settle with a guarantor for less than the full amount, usually on evidence of what the guarantor owns and earns. It may sell the debt to a buyer of distressed claims. And once it expects nothing more, it writes the balance off in its own accounts.
In the example the directors' main asset is a house with about US$0.6m of equity. After reviewing a statement of their means, the bank accepts US$0.55m paid over twelve months, against the cost, delay and uncertainty of bankrupting them. The liquidation later pays unsecured creditors four cents in the dollar, US$0.03m on the bank's claim.
// 04 — HOW IT DIFFERS FROM LOSS GIVEN DEFAULT
The two are confused because both measure what is lost after default. The shortfall is a legal debt, the amount the borrower and guarantors still owe, and it includes the default interest and costs the documents let the lender charge. Loss given default is the lender's estimate, made before default for capital and provisioning, of the economic loss as a share of the exposure, after all recoveries and the lender's own costs and discounted for the time recovery takes.
Exposure at default (debt at appointment) 2.88
Recovered: security 2.41, less receivers' and legal 0.21 2.20
guarantors 0.55
liquidation dividend 0.03
Total recovered 2.78
Economic loss before discounting: 2.88 − 2.78 = 0.10
As a share of exposure at default: 0.10 ÷ 2.88 ≈ 3.5%
On the example, the shortfall was 30 per cent of the debt at appointment, while the bank's loss is about 3.5 per cent before discounting. The gap has three parts. The guarantee paid US$0.55m and the liquidation US$0.03m. The other US$0.17m is the interest charged during enforcement: the borrower owes it, but the bank did not advance it, and LGD captures that cost instead by discounting the recoveries for the nineteen months they took. The guarantee is the largest part, which is why a lender estimating its loss reads the guarantors beside the security.

// 05 — WHERE IT DECIDES A FILE
Long before default, a lender is estimating the shortfall it could face. It sizes security on forced-sale and liquidation values because those are what enforcement produces, and it sizes guarantees against what the security might not cover, which is the work of a guarantor coverage test.
During enforcement, the shortfall is a reason to move quickly and to cooperate. In the example, seven months added US$0.38m to the debt, and a sale the owners had run with the bank's agreement might have cost less. At the end, the shortfall is often contested. A guarantor who believes an asset was sold too cheaply can challenge the sale; in New Zealand the statutory duty on a mortgagee's price is owed to guarantors as well as to the borrower. A file that shows the valuations, the marketing and the reasons for each sale is the lender's answer.

The documents the statements on this page rest on. Each was opened and checked when cited.
- High Court of England and Wales (Chancery Division), [2008] EWHC 124 (Ch), paragraphs 27 and 30 — Holds that a secured creditor is not entitled to participate in the prescribed part in respect of any shortfall in its security, the prescribed part being for unsecured creditors alone — section 03.
// QUESTIONS PEOPLE ASK
- Do I still owe the bank after it sells my property?
- If the sale did not cover the debt, yes. The sale reduces what is owed by the net proceeds, and the remainder is still a debt of the borrower, and of any guarantor within the guarantee's limit, unless the lender agrees to release it. The lender should provide an account showing the sale price, the costs deducted, the interest charged and the balance. Reading that account carefully is the first step in deciding whether to pay, negotiate or dispute it.
- Can a guarantor be made to pay the shortfall?
- Generally yes, up to the limit of the guarantee, plus whatever interest and costs the guarantee adds. That is what a guarantee is for. A guarantor can question the account, the costs charged and the price achieved on the sale, and in some markets the lender's duty on the sale price is owed to the guarantor directly. A guarantor who cannot pay in full can offer a settlement backed by evidence of means.
- Can the bank add default interest and its costs to the shortfall?
- Usually, if the loan documents provide for them, and most business loan documents do. Default interest must be charged at the rate the documents set, and enforcement costs are generally limited to those properly incurred. Once the borrower is in liquidation, the claim against it is generally fixed at the date the liquidation began, with later interest paid only out of any surplus, though a guarantee may keep interest running against the guarantor. Each item in the lender's account can be questioned.
- Will a bank accept less than the full shortfall?
- Often, where it is persuaded that pursuing the full amount would cost more or recover less. A lender weighs what the borrower or guarantor owns and earns, the cost and time of legal action or bankruptcy, and any dispute over the sale. Settlements are usually made on a written statement of means and may be paid in a lump sum or instalments. A settlement agreed in writing should say expressly that it releases the remaining debt.
