EU Competition Rules for Distribution Agreements #10: Parity/MFN Obligations (part II): designing safe and compliant clauses

Written by Banning | Nov 3, 2025 2:10:00 PM

Introduction

In Part I of this series, we outlined the new legal framework for parity (or most-favoured-nation, “MFN”) obligations under the new Vertical Block Exemption Regulation (“VBER”) and the Vertical Guidelines (“VGL”).

The 2022 reform draws a clear distinction between wide and narrow parity clauses, excluding the former from the safe harbour where imposed by providers of online intermediation services (OIS), while continuing to exempt the latter in most cases.

In this second part, we turn to the practical implications. How can parity clauses be structured to remain within the safe harbour? When does an individual assessment become necessary? And what concrete lessons can be drawn from recent enforcement experience?

Start with classification: wide, narrow, or hybrid

The first compliance step is to identify what kind of parity obligation is being proposed.

TYPE DESCRIPTION SAFE HARBOUR STATUS
Wide parity OIS provider prohibits business user from offering better terms on any competing online intermediation service or sales channel. Excluded from the block exemption (Art. 5(1)(d) VBER) → requires individual assessment.
Narrow parity OIS provider prohibits business user from offering better terms on its own direct channel (e.g. its own website or store). Covered by the block exemption, subject to general conditions.
Hybrid / mixed parity Combination of the above (e.g. prohibition on better terms on both own channel and some third-party sites). Must be broken down and assessed per element; the “wide” part remains excluded.

 

Accurate classification helps determine whether the clause can rely on the block exemption or whether an Article 101(1) assessment is required.

Drafting parity clauses within the safe harbour

If a parity clause is to remain exempt under the VBER, its scope and operation should be narrowly defined. The following drafting techniques are commonly used in practice:

  • Limit the scope to the business user’s own direct channels: The obligation imposed by the OIS provider should not extend to unrelated third-party platforms or resellers.
  • Define clearly what is covered: Specify whether "terms" relate only to price, or also to other elements such as delivery times, availability, or promotional support. Vague "best terms" formulations are risky.
  • Include carve-outs for legitimate commercial variations: Allow reasonable deviations such as short-term promotions, clearance sales, loyalty programmes, or market-specific price adjustments.
  • Make the obligation time-limited and reviewable: Parity clauses of indefinite duration may be perceived as cumulative barriers to entry. Annual review mechanisms mitigate that risk.
  • Avoid excessive monitoring or data exchange: Auditing compliance is legitimate, but real-time sharing of price data across multiple OIS could raise concerns about facilitating coordination.
  • Document efficiency justifications: In cases where parity is implemented to prevent freeriding or to facilitate specific investments, the underlying rationale should be formally documented at the time of implementation.

These techniques help ensure that parity clauses imposed by OIS providers achieve their commercial purpose without unduly restricting competition.

When individual assessment is required

Where a wide parity obligation is imposed by an OIS provider – or where the contracting parties exceed the 30% market-share threshold – the clause must be individually assessed under Article 101(1) TFEU.
In such cases, the VGL identify key factors for analysis:

  • Market power of the parties: The greater the OIS provider's or supplier's market share, the higher the likelihood of anticompetitive effects.
  • Market structure and entry barriers: In concentrated online intermediation markets, parity clauses may reinforce incumbents' positions.
  • Coverage and duration: Broad, long-term parity obligations imposed by OIS providers increase foreclosure risk.
  • Transparency effects: Where parity clauses make prices more predictable across platforms, they may facilitate tacit coordination.
  • Efficiencies: Clauses may still be justified if demonstrably necessary to prevent free-riding or to protect specific investments that benefit consumers.

Documenting these aspects is essential for any OIS provider seeking to rely on an efficiency defence under Article 101(3).

Cumulative effects and the withdrawal mechanism

Even narrow parity obligations, when imposed by OIS providers, may lose their protection in certain market contexts. Under Article 6 VBER, the Commission or a national competition authority may withdraw the benefit of the block exemption if similar clauses, taken together, have cumulative restrictive effects. The VGL explicitly mention that in concentrated platform markets, widespread use of narrow parity obligations by OIS providers can reduce competition between OIS and limit business users' ability to direct sales elsewhere.

OIS providers imposing (narrow) parity obligations in a concentrated market should:

  • Regularly assess the combined effect of parity obligations imposed across all their business users and OIS distribution partners;
  • Monitor market concentration and any guidance or statements from competition authorities in their sector;
  • Proactively consider withdrawing or waiving parity clauses in relationships or segments where cumulative restrictive effects may arise;
  • Ensure internal compliance and documentation processes to anticipate a potential withdrawal of the Article 6 VBER safe harbour in case the competitive risks become substantial;
  • Communicate transparently with business users regarding the rationale and potential adjustments to parity obligations if required by the evolving market circumstances.

Enforcement trends and private risk

Recent investigations by several national competition authorities demonstrate that parity clauses imposed by OIS providers remain on the radar. While most have focused on the online travel sector, similar issues are arising in ecommerce, digital content distribution, and mobility platforms.

In addition to public enforcement, parity obligations may expose firms to private damages claims by resellers or competitors alleging foreclosure. Companies should therefore integrate competition-law review into contract approval and compliance training processes.

Practical checklist for businesses

A few concise “do’s and don’ts” illustrate the new landscape:

Do     Don’t
Use narrow parity limited to the buyer’s own direct channels. Impose wide across-platform parity obligations without individual assessment.
Keep clauses specific, time-limited and reviewable. Include open-ended “best terms” language covering all aspects of cooperation.
Allow reasonable promotional flexibility. Prohibit any deviation whatsoever, even temporary campaigns.
Document efficiencies and investment rationales Rely on parity as a default clause without internal justification.
Monitor cumulative exposure to similar obligations across platforms. Assume that the safe harbour applies regardless of market structure

 

Outlook and key takeaways

The 2022 reform has fundamentally revised the treatment of parity obligations imposed by OIS providers:

  • Wide / across-platform parity clauses are now outside the block exemption and must be justified case by case.
  • Narrow parity clauses remain generally safe but may lose protection where cumulative effects arise.
  • The dividing line between legitimate efficiency and foreclosure risk will depend heavily on market power and market concentration.

For suppliers, OIS providers, distributors and buyers alike, the message is clear: parity clauses can still serve legitimate business purposes, but they now require more careful calibration and documentation than before.

Conclusion

Parity obligations remain a useful commercial instrument — but they are no longer a “tick-box” clause that can be inserted automatically into standard distribution or platform contracts.

Under the new VBER and VGL, businesses must tailor their parity provisions to the specific competitive context, ensure transparency of purpose, and regularly review whether market conditions still justify their use.

A thoughtful compliance approach, combining legal self-assessment with internal monitoring, will be key to staying within the safe harbour — and to avoiding unpleasant surprises from competition authorities or private challengers.
