BOC Aviation Limited provided earnings guidance for the full year ended December 31, 2017. In December 2017, The Tax Cuts and Jobs Act (H.R.1) came into effect in the USA which, among other measures, will reduce the federal corporate tax rate that the Group will use to calculate its net deferred income tax liabilities in the USA to 21% from 35% previously. As a consequence of this federal tax rate reduction, the Group's preliminary assessment of the net deferred income tax liabilities as at 31 December 2017 will be reduced by an amount within the range of $88 million to $93 million and the Group's net profit after tax for the year ended 31 December 2017 will increase by a similar amount.
