RESULTS OF OPERATIONS - 2019 Compared to 2018 (in millions): Our results for 2018 include the effect of the net gain on disposition of subsidiaries of $178.4 million and repositioning charges of $149.4 million, after the allocation of $6.9 million to noncontrolling interests, and the additional income tax expense of $3.9 million from the finalization of the provisional estimate of the effect of the Tax Cut and Jobs Act of 2017, or Tax Act, substantially offset by the impact of a lower tax rate on the net gain on disposition of subsidiaries. The following discussion of our results of operations compares 2019 to 2018 as reported and adjusted for the effects of these transactions. See page 24 for a reconciliation of the adjusted 2018 amounts. We use EBITA and EBITA Margin as additional operating performance measures that exclude the non-cash amortization expense of intangible assets, which primarily consists of amortization of intangible assets arising from acquisitions. We define EBITA as earnings before interest, taxes and amortization of intangible assets, and EBITA Margin as EBITA divided by revenue. EBITA and EBITA Margin are non-GAAP financial measures. We believe that EBITA and EBITA Margin are useful measures for investors to evaluate the performance of our business. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with U.S. GAAP. Non-GAAP financial measures reported by us may not be comparable to similarly titled amounts reported by other companies.
