The material adverse change (MAC) clause under Dutch law
A material adverse change (MAC) clause, also referred to as a material adverse effect (MAE) clause, is a provision in a share purchase agreement or merger agreement that protects the buyer against a significant deterioration in the target under Dutch contract law in the target's business, financial condition or prospects between signing and closing. Under Dutch law, MAC clauses are interpreted restrictively: Dutch courts and arbitral tribunals set a high threshold for what qualifies as a MAC, and buyers who seek to invoke the clause face a demanding burden of proof.
What is a MAC clause and how does it work under Dutch law?
A MAC clause may operate either as a condition precedent to closing or as a warranty. As a condition precedent, it gives the buyer the right to refuse completion if a MAC has occurred. As a warranty, breach entitles the buyer to damages after completion.
As a condition precedent, a MAC clause typically states that the buyer's obligation to complete the acquisition is conditional on no material adverse change having occurred in the target's business between signing and closing. If the buyer determines that a MAC has occurred, it may decline to complete and seek to recover its costs. As a warranty, the seller warrants at signing and repeats at closing that no MAC has occurred; breach gives the buyer a damages claim but does not necessarily allow it to walk away from the deal.
In Dutch M&A practice, MAC clauses are more commonly drafted as warranty qualifications than as standalone closing conditions, though both forms appear in transactions. The Dutch Supreme Court and courts of appeal have not yet produced a definitive body of case law on MAC clauses comparable to the Delaware Court of Chancery, but Dutch practitioners draw extensively on foreign jurisprudence when advising clients.
What is the threshold for invoking a MAC clause under Dutch law?
Dutch courts interpret MAC clauses narrowly and set a high threshold for invocation. Short-term setbacks, market-wide downturns, or changes that were foreseeable at signing will generally not qualify as a MAC.
The Haviltex standard, which governs the interpretation of all Dutch contracts, requires courts to ask what the parties reasonably understood the MAC clause to mean in the specific context of the transaction. Dutch legal doctrine and practice hold that a MAC must be substantial, durable, and specifically targeted at the target's business, not a general market development that affects all comparable companies.
A temporary decline in earnings, a short-term loss of a customer, or a market-wide deterioration in conditions will typically not meet this threshold. The change must be of such a character that a reasonable buyer, had it known of the change at signing, would not have entered into the transaction at the agreed price. This is a demanding standard, and buyers who attempt to invoke a MAC clause to exit a deal that has become less attractive for extraneous reasons will face significant legal risk under Dutch law.
What are the standard exclusions from MAC clauses in Dutch M&A contracts?
Sellers in Dutch M&A transactions negotiate extensively to include exclusions from the definition of MAC, ensuring that general economic risks and industry-wide developments do not allow the buyer to exit.
Standard exclusions from a Dutch M&A MAC clause include: general economic conditions; changes in financial markets, interest rates or currency exchange rates; industry-wide developments that affect the target's sector generally; changes in applicable law or regulation; geopolitical events, acts of war or terrorism; pandemics or natural disasters; and changes resulting from the announcement of the transaction itself. Sellers also seek to exclude the effect of any action taken by the target at the buyer's request.
Each of these exclusions may be subject to a carve-back provision: even if an exclusion applies, it does not protect the seller if the relevant development has had a disproportionate adverse effect on the target compared to its peers. This "disproportionate impact" carve-back restores some of the buyer's protection where a general risk materialises in a way that specifically and severely damages the target.
How do MAC clauses relate to onvoorziene omstandigheden under Dutch civil law?
MAC clauses in Dutch law contracts interact with the statutory concept of onvoorziene omstandigheden (unforeseen circumstances) under Article 6:258 of the Dutch Civil Code, which allows a court to modify or dissolve a contract where circumstances have changed beyond what the parties could reasonably have anticipated.
Where a signed SPA does not contain a MAC clause, or where the MAC clause does not cover the event that has occurred, a buyer facing a catastrophic deterioration of the target's business may seek relief under Article 6:258 of the Dutch Civil Code. This provision allows a court to modify or dissolve the contract where unforeseen circumstances have arisen that are so serious that the counterparty cannot reasonably expect performance to continue unchanged. The threshold under Article 6:258 is very high, and Dutch courts are extremely reluctant to interfere with freely negotiated commercial agreements. Nevertheless, the provision operates as a residual safety valve in extreme situations.
Consulting a contract lawyer in the Netherlands experienced in M&A is essential both when drafting MAC clauses at the time of negotiation and when assessing whether a MAC has occurred and whether it can be validly invoked.
