[1] ⁽¹⁾ Adjustments, net of tax, included in the pro forma net income above that were of a non-recurring nature include:   • 2018—elimination of (1) restructuring and integration costs ($112 million); (2) transaction costs ($37 million); and (3) debt extinguishment costs ($11 million);   • 2017—elimination of restructuring costs ($81 million); and   • 2016—elimination of restructuring costs ($7 million).

[2] Pro forma net (loss) income per share was calculated using weighted average basic and diluted shares outstanding during the fourth quarter of 2018. The effects of restricted stock, warrants and redeemable preferred stock were not included in the calculation of diluted earnings per share for 2018 and 2017, due to the net losses in those periods. 2016 diluted shares include restricted stock units and warrants; the impact of the redeemable preferred stock is antidilutive.
