The January 3, 2018, deadline for compliance with the latest revisions to the Markets in Financial Instruments Directive (MiFID II) is quickly approaching. Additionally, a bill pending in the U.K. Parliament could dramatically affect the taxation of pass-through entities in the U.K. A recent Simmons & Simmons briefing offered guidance to fund managers on preparing for MiFID II and how the pending tax changes could affect their operations. The program was moderated by Simmons partner Devarshi Saksena and featured partners Lucian Firth and Martin Shah and senior lawyer Russell Afifi. This article highlights their key insights. For additional commentary from Simmons on MiFID II, see “Simmons & Simmons and Advise Technologies Provide Comprehensive Overview of MiFID II”: Part One (Jun. 18, 2015); and Part Two (Jun. 25, 2015).
