Jones Day's clients benefit from the synergies between the competition practice and the firm's strengths in litigation, corporate and M&A, and regulatory matters. Co-led by Alexandre Verheyden and Bernard Amory, the competition team covers major Belgian-level mergers, investigations and litigation centred on alleged abuse of dominant positions/cartels, and state aid cases . In the competition litigation arena, clients benefit from the experience of Michèle Grégoire, who is one of only 20 lawyers to be a member of the Belgian Supreme Court Bar. The firm's excellent practice generates work from a mix of Belgian and global clients; Verheyden, Sébastien Champagne and associate Laurence N. Van Mullem are representing BT, Colt and Verizon in three separate damage claims in relation to an alleged abuse of dominance by Belgacom Mobile concerning low on-net tariffs. Further showcasing the firm's strengths in the telecoms sector, Yvan Desmedt has been advising Telenet/Liberty Global on a requirement to provide access to competitors to the cable market in Belgium. Elsewhere, the group stands out in matters involving other industries, such as transportation, consumer goods, energy and resource management, and financial services. Laurent De Muyter and Charles de Navacelle recently made partner.

Jones Day fields 'a very practical team' that 'looks around the corner to anticipate issues'. The group, which is jointly led by Bernard Amory and Alexandre Verheyden, is well placed to handle the complex EU and global competition issues of international clients in merger control matters, litigation, cartel and abuse of dominance investigations, and state aid cases. Its breadth and depth of antitrust expertise is complemented by cross-practice support in areas such as corporate and M&A, regulatory and litigation. In addition, it is also able to leverage the knowledge and experience of competition experts throughout the global network. In the TMT sector, Amory, Verheyden, Philipp Werner and recently promoted partner Laurent De Muyter are acting for Deutsche Telekom/T-Mobile in an EC investigation into mobile telephone network sharing agreements, and, separately, are handling its challenge before the EC of an EU member state's auction of spectrum on allegedly discriminatory terms in favour of an incumbent operator. The firm also assists Procter & Gamble with its worldwide acquisitions and divestitures; recent work includes Serge Clerckx and others acting as antitrust counsel to the client on the acquisition of Merck's worldwide consumer health business for $4.2bn, and also the dissolution of its healthcare partnership with Teva. Mario Todino, Charlotte Breuvart, Yvan Desmedt and recently promoted partner Charles de Navacelle are also recommended. Kaarli Eichhorn joined from General Electric in April 2018.

  • US rules regarding offshore accounts

    The Hiring Incentives to Restore Employment Act 2010, enacted on 18 March 2010, imposes a new US withholding tax and reporting regime, known as the Foreign Account Tax Compliance Act (FATCA). The FATCA regime applies generally to payments made after 31 December 2012, except on obligations (to be defined in future guidance) outstanding on 18 March 2012. Substantial effort is required by foreign entities to bring their worldwide operations and policies into compliance with the FATCA rules as of the effective date.‚Ä©
