A material adverse change clause lets a lender refuse to fund, or declare a default, if something significantly worsens the borrower's business, assets or financial condition. It appears in three places: as a condition to closing in the commitment letter, as a representation that no such change has occurred, repeated each time you draw on a line, and sometimes as an event of default on its own. It is usually defined loosely, which is the point from the lender's side. Borrowers push to narrow it, drop words like "prospects", and keep it out of the events of default.
- What it is
- A lender's right to act on a serious deterioration not covered by a specific covenant
- Before closing
- A condition: no MAC since the commitment or the last financial statements
- After closing
- A representation repeated at each draw, and sometimes an event of default
- Why it worries borrowers
- Vague wording leaves the judgment with the lender
- What to negotiate
- A narrow definition, no "prospects", and no stand-alone default
Three places a MAC clause shows up
People speak of "the MAC clause" as if it were one provision. In a loan it is usually three, each doing a different job, and they should be read and negotiated separately.
| Where it appears | What it says | What it lets the lender do | When it matters most |
|---|---|---|---|
| Commitment letter or term sheet, as a condition to closing | No material adverse change has occurred since a stated date | Decline to close on the committed terms | Between commitment and funding, especially in an acquisition |
| Credit agreement, as a representation | No material adverse change since the last financial statements delivered | Refuse a new advance if the representation cannot be repeated | Every draw on a revolving line |
| Credit agreement, as an event of default | A material adverse change occurs, or the lender in good faith believes one has | Declare a default, charge default interest, accelerate | Whenever the business has a hard year, whether or not covenants are met |
The first is ordinary and hard to avoid: a lender that commits ahead of closing will not fund a business that has fallen apart in between. The second is also standard in any revolving line, because every borrowing request restates the representations. The third is the one that gives a lender the widest discretion, and the one worth the most negotiating effort.
How loosely it is usually defined
A typical definition refers to a material adverse effect on the borrower's business, operations, assets, liabilities, condition (financial or otherwise) or prospects, or on its ability to perform its obligations, or on the lender's rights or collateral. Every one of those words is doing work, and none of them has a number attached. "Material" is not defined. "Prospects" invites a debate about the future rather than a test of the present. "Condition (financial or otherwise)" reaches almost anything.
The looseness is deliberate. Financial covenants such as a debt service coverage test measure the past quarter. A MAC clause is how a lender protects itself against the thing that has not reached the financial statements yet: the loss of the largest customer, a license revoked, a fire at the only plant, a lawsuit that could bankrupt the company. Courts have generally required a serious and lasting deterioration before a MAC is established, not a bad quarter, but a borrower of this size rarely wants to test that in litigation. In practice the question is how much leverage the clause gives the lender in a negotiation.
A MAC clause is rarely the only reason a lender acts. It is the reason a lender can act before the covenant breach arrives, or refuse the next draw while the conversation happens.
The MAC as a closing condition
Between the commitment letter and funding, a MAC condition lets the lender walk away if the business deteriorates. That matters most in an acquisition, because the buyer has usually signed a purchase agreement with its own MAC definition, drafted by different lawyers for a different purpose. If the lender's definition is broader than the purchase agreement's, there is a gap: an event that lets the lender decline to fund, but does not let the buyer out of the purchase. The buyer is then bound to close without the money to do it.
The fix is to align the two. Buyers negotiate for the lender's MAC condition to track the purchase agreement's definition, or to apply only to the target business as measured in the purchase agreement, and for the lender to confirm in the commitment that its business due diligence is complete. A lender that has already reviewed the quality of earnings work and the target's latest figures has less reason to keep a broad escape route. See term sheet vs commitment letter for when a lender is actually committed.
In a refinancing the risk is smaller but real. If the business has a soft quarter between commitment and closing, a broadly worded condition gives the lender room to reprice or resize. Knowing the date the MAC is measured from, and what financial statements it is measured against, tells you how exposed you are.
The MAC as a representation and a default
After closing, the representation that no material adverse change has occurred is repeated every time the borrower requests a new advance under a line of credit. If the borrower cannot truthfully make it, the lender does not have to fund. This is how a MAC clause most often bites in real life: not as an acceleration of the loan, but as a lender declining a draw on a line the business was counting on. See what to do when a bank cuts or freezes a line.
As an event of default in its own right, the MAC is stronger still. It lets the lender call a default without pointing to any covenant, and some versions turn on the lender's own belief rather than on facts: the lender "in good faith believes" a material adverse change has occurred, or "deems itself insecure". Smaller bank loans and demand notes often include language of this kind. Larger, more negotiated credit agreements often drop the MAC default altogether and let the financial covenants and specific defaults do the work.
How borrowers narrow it
A borrower rarely removes the MAC clause entirely, but there is usually room to make it more objective. The requests that are most often accepted:
- Strike "prospects". Tie the definition to the business as it is, not to forecasts of what it might become.
- Measure the business as a whole. A change must be material to the borrower and its subsidiaries taken together, not to one location or product line.
- Tie it to repayment. Define the MAC by its effect on the borrower's ability to pay the loan, which is the lender's real concern.
- Carve out known matters. Anything disclosed to the lender before closing, such as a pending lawsuit or a customer already lost, should not later count as a MAC. Put it on a disclosure schedule.
- Remove the stand-alone default. Keep the MAC as a closing condition and a draw condition, and let the specific events of default and financial covenants govern after closing.
- Replace subjective triggers. Resist language that turns on the lender's belief or feeling of insecurity, as opposed to a change that has actually occurred.
How far a lender will go depends on the lender and the size and strength of the deal. A bank lending a modest term loan to a single-location business may keep its standard form. A private credit fund in a competitive process for a larger company will often accept a narrow definition. The term sheet stage, before legal fees are spent, is the time to raise it.
Where Transparent comes in
The best protection against a MAC dispute is a lender that already knows the bad news. Transparent's lender package sets out the business's risks, including customer concentration, pending disputes and the latest trading, in the underwriting memo and lender presentation, so the lender commits with them in view rather than finding them later. Disclosed risks are also the easiest to carve out of the definition. When term sheets come back, Transparent compares the conditions to closing across lenders, including how each defines a material adverse change, alongside price and structure.

Common questions
- What counts as a material adverse change?
- Whatever the loan documents define it as. Most definitions are loose on purpose. Courts have generally required a serious, lasting deterioration rather than a bad quarter, but a borrower should rely on a narrow definition, not on litigation.
- Can a lender refuse to fund a line of credit because of a MAC?
- Yes, if the credit agreement makes the absence of a material adverse change a condition of each advance and the borrower cannot truthfully repeat that representation. This is the most common way the clause is used.
- Is a MAC clause the same as an insecurity clause?
- They overlap. An insecurity clause lets the lender act when it deems itself insecure, which turns on the lender's belief. A MAC clause usually turns on a change having occurred. Borrowers prefer the latter.
- Can I get the MAC clause removed?
- Rarely as a closing condition. More often you can narrow the definition, strike "prospects", carve out disclosed matters and remove the MAC as a stand-alone event of default.
- Why does the MAC clause matter so much in an acquisition?
- Because the buyer is bound by the purchase agreement. If the lender's MAC is broader than the purchase agreement's, the lender can decline to fund while the buyer still has to close.
