Reading a MAC Clause Before You Actually Need To

A general MAC clause is broadly worded, typically referring to any change that could materially and adversely affect your business, financial condition, or ability to repay, without listing specific triggering events. A specific MAC instead ties the clause to defined events: losing a named key customer above a certain revenue threshold, an adverse judgment in a specified litigation, or a specified drop in a financial metric. Specific MAC language is generally better for borrowers, since it removes ambiguity about what actually counts, while a broad general MAC gives the lender more room to argue a triggering event occurred when the relationship has soured for other reasons.

A MAC clause functions mainly as a backstop against a catastrophic, unanticipated event between signing and an actual funding, or during an ongoing facility with multiple draws over time, not as a routine covenant a lender expects to invoke over minor underperformance. Lenders generally prefer their more specific financial covenants, minimum cash, debt-to-EBITDA ratios, DSCR, as the primary early warning tool, since those trigger clearly and predictably, reserving the MAC clause for something outside what a normal covenant would catch.

For example, a lender's covenant package might include minimum cash and a debt service coverage ratio alongside a general MAC clause. Your finance team learns that a key supplier is failing. That event doesn't breach any covenant today, so a lender who wanted to decline a draw would have to argue a MAC instead. A useful habit is to keep a short memo, refreshed each quarter, that sets out what a lender would have to prove under your clause, how you would answer, and which covenant would trip first. Sharing that view early turns a later conversation into planning rather than a dispute. The common mistake is assuming the clause is irrelevant because the lender has never mentioned it, when a draw request is often the moment it gets read closely.

Courts reviewing a lender's attempt to invoke a general MAC clause have generally set a high bar, requiring the change to be durationally significant, not a short term or seasonal dip, and to threaten the borrower's overall earnings potential in a substantial way, not merely disappoint against a specific quarter's projection. This history is one reason lenders often prefer to rely on their specific financial covenants, which have a clear, mechanical trigger, rather than betting on a MAC argument holding up if a borrower pushes back.

Say a company has an undrawn commitment on a facility and requests a draw shortly after losing a large customer that made up a meaningful share of revenue. A lender citing a general MAC clause to decline the draw is making a real legal argument, but not necessarily a certain one, since the borrower can push back on whether a single customer loss meets the durational and severity bar courts have generally required. This is exactly the scenario where having negotiated a specific MAC clause upfront, one that clearly does or doesn't capture a single customer concentration event, would have made the outcome predictable instead of a legal fight.

Push for specific, defined triggering events rather than open-ended general language wherever the lender will agree to it, and ask for a notice and cure period even on the MAC clause itself, giving you a chance to address or explain a triggering event before the lender can decline a draw or accelerate the loan outright. If your business has a known concentration risk, one large customer, one key contract, negotiate an explicit carve-out or a defined threshold for that specific risk rather than leaving it to a general clause's ambiguous language to resolve later.

Also ask who at the lender actually has authority to invoke the clause. Some credit agreements require sign-off from a senior credit committee rather than a single relationship manager before a MAC declaration can be made, which in practice makes the clause slower and rarer to invoke than the bare contract language suggests. Knowing that internal process helps you gauge how seriously to take a MAC threat if one ever comes up.

Terms to ask for in the MAC language:

• Ask for specific, defined triggering events instead of open-ended general language, so both sides know exactly what counts as a material adverse change.
• Request a notice and cure period on the MAC clause, giving you a chance to address or explain a triggering event before the lender declines a draw.
• Negotiate an explicit carve-out or defined threshold for a known concentration risk, such as one large customer or one key contract.
• Ask who at the lender has authority to invoke the clause, since a required credit committee sign-off makes a declaration slower and rarer.
• Confirm whether the wording covers only company-specific changes or could also reach broader market downturns.
