_______________

(a)
The statutory or “expected” tax rates are the U.K. rates of 19.0% for 2019, 19.0% for 2018 and 19.25% for 2017. The 2017 statutory rate represents the blended rate that was in effect for the year ended December 31, 2017 based on the 20.0% statutory rate that was in effect for the first quarter of 2017 and the 19.0% statutory rate that was in effect for the remainder of 2017.

(b)
These amounts reflect the net impact of differences in the treatment of income and loss items between financial reporting and tax accounting related to investments in subsidiaries and affiliates including the effects of foreign earnings.

(c)
On December 27, 2019, updated legislation was enacted in the Netherlands to delay and lessen the corporate income tax rate reduction that had previously been enacted in December 2018. The current rate of 25% will now be maintained in 2020 and will be reduced to 21.7% in 2021; the previous reduction schedule reduced from the current rate of 25.0% to 22.5% in 2020 and 20.5% in 2021. Substantially all of the impacts of the new rate change in the Netherlands on our deferred tax balances were recorded during the fourth quarter of 2019, modifying the impacts of the 2018 rate change that were previously recorded during the fourth quarter of 2018. In 2017, a Belgian income tax rate reduction was signed into law. The Belgian statutory tax rate decreased from 33.9% to 29.58% beginning in 2018, and in 2020, this rate will further decrease to 25.0%. Also in 2017, the U.S. corporate income tax rate was reduced from 35.0% to 21.0% effective beginning in 2018. Substantially all of the impacts of the tax rate changes in Belgium and the U.S. on our deferred tax balances were recorded during the fourth quarter of 2017.

(d)
Amounts reflect adjustments (either a benefit or expense) to the “expected” tax benefit (expense) for statutory rates in jurisdictions in which we operate outside of the U.K.

(e)
As further discussed below, the liability we have recorded for the Mandatory Repatriation Tax (as defined and described below) is significantly lower than the amount included in our income tax expense due in part to the expected use of carryforward attributes in the U.S., all of which were subject to valuation allowances prior to the initial recognition of the Mandatory Repatriation Tax during the first quarter of 2018.
