Key takeaways

  • §The Authority clearly prefers structural remedies (divestitures) over behavioural ones.
  • §A structural horizontal overlap usually requires a divestiture.
  • §An up-front approved buyer signals heightened scrutiny.

Short answer

The Authority favours structural remedies. A behavioural commitment is only accepted for a precise, verifiable and bounded problem; a structural horizontal overlap calls for a divestiture, sometimes with an up-front approved buyer.

Behavioural vs structural: the basic distinction

A structural remedy durably changes the structure of the market — typically through the divestiture of stores or assets to a competitor. A behavioural remedy only frames the firm's future conduct, without touching its perimeter.

The French Competition Authority, like most authorities, shows a clear preference for structural remedies: they are clear, verifiable and require no ongoing monitoring. Behavioural commitments are the exception, accepted when the problem is precise and temporary.

When divestiture becomes unavoidable

Whenever a transaction creates a strong structural overlap on a local market — high market shares, few credible alternatives for the consumer — the Authority generally requires a divestiture.

Decision 20-DCC-116 (Soditroy / E.Leclerc) is instructive: the Authority rejected a mere reduction in sales area. Without removing the structural overlap, the proposed remedy was deemed inadequate.

When a behavioural commitment can suffice

Behavioural remedies keep their place in precise configurations: a limited vertical problem, access to an infrastructure, a fixed duration, a simple monitoring mechanism. They are better received when easy to supervise and bounded in time.

Conversely, the more horizontal and durable the problem, the more the Authority will doubt that a conduct promise truly resolves the harm to competition.

  • §One-off, verifiable problem: behavioural remedy is conceivable.
  • §Structural horizontal overlap: divestiture is usually required.
  • §Up-front approved buyer: a signal of heightened scrutiny.

The approved buyer as a marker of scrutiny

When the Authority requires an approved buyer before closing (up-front buyer), it signals a high level of scrutiny: it wants to ensure the divestiture will be effective and the buyer a viable competitor.

This requirement appears in the tightest markets, notably overseas, where decision 20-DCC-72 (GBH / Vindémia) combined divestitures with an up-front approved buyer.

Preparing remedies upstream

Anticipating the expected type of remedy avoids losing time during negotiation. It requires knowing the sector's precedents: which commitments were accepted, which were rejected, and in which market configurations.

This is exactly the kind of question L420 handles: 'in which cases was a behavioural commitment deemed insufficient?' surfaces the relevant decisions, with their verifiable references.

Frequently asked questions

Why does the Authority prefer structural remedies?

Because they durably resolve the competition problem without ongoing monitoring: a divestiture is clear, verifiable and final, whereas a behavioural commitment requires continuous supervision.

What is an up-front approved buyer?

It is the requirement, before closing, to identify and have the buyer of the divested assets approved. It ensures the divestiture is effective and the buyer viable — a marker of heightened scrutiny.
