[1] During fiscal 2018, the Company adopted authoritative guidance which requires all income tax effects of stock awards (resulting from an increase or decrease in the fair value of an award from grant date to the vesting date) to be recognized in the income statement when the awards vest or are settled. This is a change from previous guidance that required such activity to be recorded in paid-in capital within stockholders’ equity. As a result, the Company recorded tax shortfalls of approximately $1.3 million in the Company’s income tax expense during fiscal 2018.

[2] All fiscal quarters presented consisted of 13 weeks with the exception of the quarter ended February 3, 2018 which consisted of 14 weeks.

[3] These accumulated other comprehensive income (loss) components are included in the computation of net periodic defined benefit pension cost. Refer to Note 12 for further information.
