Learn how a Material Adverse Change clause shifts risk in commercial mortgage commitments and why it matters to lenders and borrowers.
A Material Adverse Change (MAC) clause is contract language that allows a lender to suspend funding or terminate a commitment if a significant negative change occurs in the borrower, collateral, or relevant market conditions between commitment and closing. In commercial real estate lending a MAC can reference deterioration in financial statements, major tenant bankruptcies, regulatory changes, or physical damage to the property. MAC clauses vary in scope and are often negotiated to define the threshold of what constitutes a material adverse event.
Brokers and sponsors should scrutinize MAC language during commitment negotiations, seeking narrow, objectively defined triggers and carveouts for normal market fluctuations or pre-agreed operational changes. If a lender insists on broad MAC rights, negotiate caps on the lender's discretion or require clear standards and notice cure periods. Use diligence to identify risks that might activate a MAC, such as tenant concentration, environmental exposure, or upcoming lease expirations, and present mitigation strategies to the lender to reduce the likelihood of invocation.
The MAC clause directly affects funding certainty and deal risk allocation; a broadly drafted MAC gives lenders latitude to walk from a transaction, potentially leaving borrowers without financing at a late stage. For sponsors it influences capital planning, contingency reserves, and reputational risk. For lenders it serves as a backstop to manage unexpected deterioration. Clear MAC drafting balances the lender's need for protection with the borrower's need for predictable access to committed capital, reducing disputes and financing failures.
