On 30 November 2017, MCH Group Ltd. acquired 67.5% of the shares in Masterpiece London Ltd, which organises the collectors' event of this same name at the Royal Hospital Chelsea in London each summer. The remaining 32.5% of the shares are held by the current shareholders. Christophe Biollaz, Head of Finance & Administration and a member of the Executive Board, has taken the decision to leave the MCH Group in the course of the coming year, at his own request, and to take up new professional challenges.

He joined the company on 1 December 2013 and has held the post of Chief Financial Officer (CFO) since 1 January 2014. The Board of Directors and management greatly regret the forthcoming departure of Christophe Biollaz. Marco Fazzone, Managing Director of Design & Regional Art Fairs, will be leaving MCH Group at his own request at the end of January 2018 and taking on a new professional challenge.

Frank Lasry will be the new managing director of the Design & Regional Art Fairs business unit as of 1 February 2018. Since 2014, he has been Chief Operating Officer (COO) at Phillips Auctioneers Ltd. and, prior to this, held various operational and managerial positions at Christie's International in London, Paris, Hong Kong and Dubai for 12 years.
