[1] During the fourth quarter of fiscal 2018, the Company reclassified net royalties received on the Company’s inventory purchases of licensed product from net revenue to cost of product sales. Accordingly, net revenue has been adjusted for fiscal 2017 and fiscal 2016 to conform to the current period presentation. This reclassification had no impact on previously reported earnings from operations.

[2] The Company operates on a 52/53-week fiscal year calendar, which ends on the Saturday nearest to January 31 of each year. The results for fiscal 2018 included the impact of an additional week which occurred during the fourth quarter ended February 3, 2018.

[3] During the fourth quarter of fiscal 2018, the Company reclassified net royalties received on the Company’s inventory purchases of licensed product from net revenue to cost of product sales. Accordingly, net revenue by geographic area has been adjusted for fiscal 2017 and fiscal 2016 to conform to the current period presentation.

[4] 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.
