Material Adverse Change Clause: What a Lender Can Prove

Easy to write, hard to prove, useful before it is used.

BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED · 6 MIN READ

// THE SHORT ANSWER

A material adverse change clause is a lender's contractual response to a serious decline that no payment date or financial covenant has yet caught. The hard part comes when it is used. Under the leading English decision, a lender relying on one carries the burden of proof, generally has to show the change from the borrower's financial information, and cannot rely on what it knew when it signed. A lender that gets it wrong may itself be in breach. So the clause does most of its work unused, as the reason a borrower in decline answers the telephone.

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.

PART OF Loan Covenants, Explained

// 01 — THE GAP THE CLAUSE IS WRITTEN FOR

Covenants are tested on dates and on historical numbers. A twelve-month earnings figure can take a long time to show bad news, because each new quarter replaces only one old one. In that interval the borrower may have lost a licence, a customer or a plant, and every test it has been set still passes. The clause exists for that interval. It lets the lender respond to substance before the arithmetic has caught up.

It usually appears in one or both of two places. As an event of default, it may allow the lender to accelerate. As a representation repeated on each drawing, that no material adverse change has occurred since the last accounts, it may allow the lender to decline a further advance. The second is the milder form.

// 02 — HOW IT IS WRITTEN, AND WHAT MUST BE SHOWN

Two drafting choices settle most of the argument. The first is the subject: the borrower's financial condition alone is narrow, while business, assets, operations or prospects reach much further, and some clauses instead ask whether the borrower can perform its payment obligations. The second is who decides. Some clauses make the test an objective fact and others turn on the lender's opinion, a form that favours lenders but does not remove all scrutiny.

The leading English decision is [2013] EWHC 1039 (Comm). On a clause about financial condition it held that the assessment normally starts with the company's financial information, though other compelling evidence can count. A change counts as material only where it makes a real difference to whether the borrower can meet its obligations, repayment above all, and it must not be merely temporary. A lender cannot rely on circumstances it knew about at signing, unless they worsen so much that they become different in kind. The lender bears the burden of proof. That decision binds no court in New Zealand or Australia, although courts there may find it persuasive.

Australia adds a limit of its own. Under the Banking Code of Practice, a subscribing bank will not include an event of default based on unspecified material adverse changes in a standard-form loan to a customer within the Code's small-business test. Larger and individually negotiated loans remain a matter for their own drafting.

// 03 — THE EXAMPLE

A contract blender of car-care products, constructed for this page like every figure in it, has a US$9m term loan and US$3m drawn on a US$5m revolving line. Its covenant is net debt to twelve-month EBITDA of no more than 3.50 times, tested half-yearly. Net debt is held flat for simplicity. In April its largest customer, 32% of volume, gives notice that it will move to its own plant in December. The forecast:

Test date LTM EBITDA Net debt ÷ EBITDA
June, this year 5.0 12 ÷ 5.0 = 2.40×
December 4.9 12 ÷ 4.9 = 2.45×
June, next year 3.9 12 ÷ 3.9 = 3.08×
December, next 2.9 12 ÷ 2.9 = 4.14× first breach of 3.50×

The covenant will not fail for some twenty months. In May the blender asks to draw a further US$2m for a new blending line. Each drawing repeats a representation that no material adverse change has occurred. The 3.50 times belongs to the example and is not a market norm.

What can the lender show? The accounts do not yet show any change. If the clause speaks only of financial condition, the English approach makes this difficult: the evidence is a forecast, and the borrower's finances today are as they were. In the English case, the court refused to treat future funding needs that were not yet liabilities as part of the financial condition at the date in question. If the clause also covers business or prospects, the case is much stronger. A customer of that size leaving for good is neither temporary nor trivial.

The lender does not declare anything. It writes to reserve its rights, says the drawing cannot proceed while the effect is assessed, and asks for a revised forecast and a plan to replace the volume. Three weeks later the two sides agree monthly reporting, and the blending line is scaled back and funded partly by the owners. The lender has what it needed: a borrower at the table twenty months early.

// 04 — HOW IT DIFFERS FROM THE PROTECTIONS BESIDE IT

A financial covenant is a precise test on a known date: it passes or fails, and a compliance certificate settles it. A material adverse change clause is general and has to be argued. A review event is the same concern, reduced to a specific listed fact, with a negotiation built in.

The label also travels. Material adverse effect is often a defined term used to qualify other clauses, such as a breach of law that counts only if it has that effect, whereas a material adverse change is itself the event. And where funds must be certain, as in certain funds lending, the lender normally gives the clause up for the acquisition drawing.

// 05 — WHERE IT DECIDES A FILE

The risk of using the clause falls on the lender. A lender that refuses a drawing or accelerates without being entitled to may be liable for substantial damages, and an acceleration can set off cross-defaults and insolvency that would be hard to undo. So lenders generally invoke it beside something firmer, such as a missed payment or a late certificate, and many will want legal advice first.

Its practical value lies in the letter that mentions it. A borrower knows the clause is there, so a request for information gets an answer. For borrowers, negotiation tends to focus on removing prospects, tying the test to ability to pay, excluding general market and industry conditions, and making the test objective. Those are the words to read in the facility letter.

  1. High Court of England and Wales (Commercial Court), [2013] EWHC 1039 (Comm) — paragraphs 345 to 364 — Financial condition is assessed primarily from financial information; a material change significantly affects ability to perform and is not merely temporary; known circumstances are excluded; the lender bears the burden — section 02.
  2. Australian Banking Association, Banking Code of Practice (2025) — paragraph 92 and the definition of Small Business — A subscribing bank will not include an event of default based on unspecified material adverse changes in a standard-form small-business loan — section 02.

// QUESTIONS PEOPLE ASK

Can a bank call a loan because of a material adverse change?
If the agreement makes it an event of default and the change can be established, yes, but banks rarely rely on it alone. The lender has to meet the clause's own test, and on English authority it carries the burden of proof. A wrong call can expose it to a damages claim. Most lenders therefore use it alongside a harder breach or as the basis for reserving rights and requesting information. Under the Australian Banking Code, a subscribing bank's standard-form small-business loans may not contain an unspecified version.
What counts as a material adverse change in a loan agreement?
Whatever the clause says, read against the facts. Under the leading English case, a change in financial condition has to significantly affect the borrower's ability to perform, particularly to repay, and it must not be merely temporary. A serious fall in earnings or the loss of a principal customer can qualify, depending on the words. A pre-existing difficulty the lender already knew of usually cannot, unless it has grown into something materially different.
Does a recession or market downturn count as a material adverse change?
Not of itself, on the usual reading. A clause directed at the borrower's financial condition requires a change in that borrower, so a general downturn is relevant only so far as it can be shown to have damaged this business in a significant and lasting way. Some clauses expressly exclude general market or industry conditions, and others expressly include them. A lender that seeks to rely on a downturn should expect to have to identify its specific effect on the borrower.
What is the difference between a MAC and a MAE clause?
The terms are often used loosely for one another. In careful drafting, a material adverse change is an event in itself: something has altered since a stated date. A material adverse effect is usually a defined consequence used to limit other provisions, so that a breach of a law or contract matters only if it has that effect. Read the definition in the document, because the two labels can be used in either way.
