[1] All fiscal quarters presented consisted of 13 weeks with the exception of the quarter ended February 2, 2013 which consisted of 14 weeks.

[2] The Company has made certain reclassifications to the prior year’s consolidated financial statements to conform to classifications in the current year. During each of the fiscal quarters in the year ended January 28, 2012, the Company reclassified certain retail distribution costs from selling, general and administrative expenses to cost of product sales to conform to current period presentation. This reclassification had no impact on previously reported earnings from operations, net earnings or net earnings per share.

[3] Per common share amounts for the quarters and full years have been calculated separately. Accordingly, quarterly amounts may not add to the annual amount because of differences in the average common shares outstanding during each period.

[4] In January 2013, the Company settled a tax audit dispute in Italy, resulting in a charge of $12.8 million in the fourth quarter of fiscal 2013, in excess of amounts previously reserved, which was partially offset by unrelated tax benefits of $4.0 million. Refer to Note 9 for further detail regarding the tax settlement charge.

[5] During the quarter ended July 30, 2011, the Company experienced a temporary disruption in service with a former third party logistics service provider in Europe. On July 29, 2011, the Company entered into a settlement agreement with this service provider to facilitate a transition to a new service provider and recorded a settlement charge of $19.5 million related to amounts paid in connection with this agreement. The settlement charge is included within operating expenses of the Europe segment for the quarter ended July 30, 2011.
