Most-favored-nation / parity clause review and remediation
mfn-parity-clause-reviewDomain: competitionType: processDescription
Most-favored-nation (MFN) and parity clauses are the contract terms that say a seller on one platform cannot offer better prices, terms, or inventory anywhere else. They are the textbook example of a contract clause that looks defensible from inside a single deal (the platform is just protecting itself against being undercut on its own marketplace) and indefensible across the market, because every platform writing the same clause produces a system in which prices cannot fall on any platform. Competition regulators have been steadily un-defending these for over a decade: the EU Commission's Booking.com decision (2024) and the German Federal Cartel Office's earlier Hotel Reservation Service work treated wide MFN clauses as restrictions of competition by object, and the EU's Vertical Block Exemption Regulation 2022 narrowed the safe harbor for narrow MFN clauses on online intermediation services. The operational system surfaces these clauses in the platform's contracts (both the platform-to-merchant terms the company authors and the merchant-to-platform terms the company agrees to as a marketplace participant) and routes them through competition-law review before signature, with a remediation track for legacy contracts that already contain them. The hard part is usually the legacy track, because the clauses tend to have been baked into standard-form merchant agreements years before anyone thought to flag them.
Required by (3 regulations)
- US Antitrust (Platforms)
US framework: MFN clauses are evaluated under rule-of-reason analysis under Sherman Act §1, with the DOJ and FTC having scrutinized them in healthcare, e-commerce, and platform contexts. Wide MFN clauses (across all rivals) draw more skepticism than narrow ones (tied to a single rival's price). State enforcement also active — Massachusetts AG and others have litigated MFN cases.
Sherman Act, 15 U.S.C. §1; FTC Act, 15 U.S.C. §45
- UK Competition (Platforms)
UK framework: wide retail-MFN clauses on online intermediation services have been treated as Chapter I infringements; narrow retail-MFNs receive case-by-case scrutiny. The CMA has signalled continued enforcement attention post-Brexit, mirroring the EU position adopted in Booking.com.
Competition Act 1998 c.41 Chapter I
- EU Competition (Platforms)
EU framework: wide retail-MFN clauses on online intermediation services excluded from the VBER 2022 safe harbour (Article 5(1)(d)) and treated as restrictions of competition by object outside Article 101(1); narrow retail-MFN clauses subject to the 30% market-share threshold. Booking.com (April 2024) is the canonical recent precedent.
