[1] | The total carrying value of goodwill of companies acquired as of December 31, 2018 and December 31, 2017, in the table above is reflected net of $1,026,702 of accumulated impairment charges, of which $716,925 was recorded in the global components business segment and $309,777 was recorded in the global ECS business segment.
[2] | The total carrying value of goodwill of companies acquired as of December 31, 2016 in the table above is reflected net of $1,018,780 of accumulated impairment charges, of which $716,925 was recorded in the global components business segment and $301,855 was recorded in the global ECS business segment.
[3] | Net income attributable to shareholders includes a U.S. Tax Act benefit of $28.3 million and expense of $124.7 million during the fourth quarter of 2018 and 2017, respectively.
[4] | Net income attributable to shareholders includes a loss on extinguishment of debt of $58.8 million during the second quarter of 2017.
[5] | Quarterly net income per share is calculated using the weighted-average shares outstanding during each quarterly period, while net income per share for the full year is calculated using the weighted-average shares outstanding during the year. Therefore, the sum of the net income per share for each of the four quarters may not equal the net income per share for the full year.
[6] | Stock-based compensation awards for the issuance of 651 shares, 380 shares, and 766 shares for the years ended December 31, 2018, 2017, and 2016, respectively, were excluded from the computation of net income per share on a diluted basis as their effect was anti-dilutive.
