“Although cost was an important factor, our relationship with LexisNexis, their responsiveness, flexibility, and the integration available with other products were key factors.”

Coordinated effects (mergers) meaning

What does Coordinated effects (mergers) mean?
Coordinated effects (mergers) describes harm that arises when a merger makes it easier for rival firms, including the merged entity, to align their behaviour without an explicit agreement—for example by increasing prices, reducing output, slowing innovation, or dividing customers or territories. These effects can occur in horizontal and, less commonly, non-horizontal mergers where the deal increases market transparency or symmetry, removes a “maverick”, strengthens retaliation mechanisms, or otherwise facilitates monitoring, so that tacit co-ordination is created or reinforced. In UK merger control, the CMA assesses coordinated effects under the substantial lessening of competition (SLC) test in the Enterprise Act 2002, guided by its Merger Assessment Guidelines; the term is descriptive rather than statutory. In Ireland, the CCPC applies the same SLC test under the Competition Act 2002 (as amended), informed by EU case law and the EU Merger Regulation’s SIEC framework (including collective dominance). Usage is broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland. Typical indicators include: high concentration and barriers to entry; stable demand and similar products; price transparency and interactions; capacity constraints; weak buyer power; history or risk of collusion. Coordinated effects are distinct from unilateral effects and can justify remedies or prohibition.

EU Merger Control under the EUMR: SIEC Test including CK Telecoms 2023, 2024 Market Definition, Horizontal/Non‑Horizontal Effects, Buyer Power, Efficiencies, Failing Firm, Ancillary Restraints and Joint Ventures

This Practice Note explains how the European Commission (the Commission) undertakes the substantive appraisal of mergers under the EU Merger Regulation (EUMR). Where a deal falls within the EUMR, the Commission must decide whether the concentration is compatible with the single market. Under the EUMR, any concentration that brings about a significant impediment to effective competition (SIEC) in the internal market, or a substantial part of it, in particular through the creation or strengthening of a dominant position, must be declared incompatible with the single market. By contrast, a concentration that does not lead to a SIEC in the internal market, or in a substantial part of it, must be cleared (ie deemed compatible with the single market). The SIEC test The SIEC test was introduced into EU competition law to close a gap identified by the European Courts when assessing the Commission’s attempts to address non‑coordinated effects in oligopolistic markets that at the same time did not trigger either single‑firm or collective dominance (which had originally limited...

Namibian merger control: thresholds, control test, joint ventures, foreign-to-foreign deals, notification, timelines, public interest, penalties, and draft reforms

NOTE—to check whether notification thresholds in Namibia and across the globe are satisfied, consult: Where to Notify. Introduction The merger control framework in Namibia is set out in Chapter 4 of the Namibian Competition Act 2 of 2003 (the Act) together with the merger control rules promulgated under the Act (the Rules). Competition Law in Namibia is implemented through coordinated efforts of several authorities, namely the Namibian Competition Commission (Commission), the Minister of Industrialisation and Trade (Minister), and the Namibian High Court. Where the applicable financial thresholds are reached, merger filings are compulsory and must be submitted to the Commission. The Minister may, on application, review decisions of the Commission. Under section 42 of the Act, a ‘merger’ arises where one or more undertakings, directly or indirectly, obtain or create direct or indirect control over all or part of another undertaking’s business...
