These items adversely impacted net income (loss) attributable to A&F by $4.1 million and $8.0 million for the first and second quarters of Fiscal 2018, respectively, and benefited net income (loss) attributable to A&F by $1.5 million and $5.3 million for the third and fourth quarters of Fiscal 2018, respectively.

[3] Net income (loss) attributable to A&F for Fiscal 2017 included certain items related to asset impairment, legal charges and discrete net tax items related to the Act. These items adversely impacted net income (loss) attributable to A&F by $4.5 million, $10.4 million and $23.0 million for the second, third and fourth quarters of Fiscal 2017, respectively.

[4] Net income (loss) per share for each of the quarters was computed using the weighted average number of shares outstanding during the quarter while the full year is computed using the average of the weighted average number of shares outstanding each quarter; therefore, the sum of the quarters may not equal the total for the full year.
