US Tax reform impact

London Stock Exchange Group plc (LSEG or Group) has completed initial assessments of the impact from changes arising from the US Tax Cuts and Jobs Act, signed into US law at the end of December 2017. While the Act reduces the US Corporate tax rate payable on US earnings, it also eliminates or reduces some tax deductions currently available to LSEG. In summary, there is expected to be no material impact on LSEG, in part due to the manner in which US acquisitions are financed and also due to the introduction of a new base erosion anti-abuse tax which will apply to payments for services provided to our US operations by the wider Group.

Further evaluation of the changes will take place as part of the preparation of the Group's 2017 financial results, and any additional update will be provided on announcement of Preliminary results on 2 March 2018.
