[1] All fiscal quarters presented consisted of 13 weeks.

[2] 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.

[3] During the first quarter of fiscal 2014, the Company implemented plans to streamline its structure and reduce expenses in both Europe and North America. During the second quarter of fiscal 2014, the Company expanded these plans to include the consolidation and streamlining of certain operations in Europe and Asia. These actions resulted in restructuring charges of $2.3 million, $6.1 million, $1.9 million and $2.1 million during the first, second, third and fourth quarters of fiscal 2014, respectively. Refer to Note 9 for further detail regarding the restructuring charges.
