[1] Stores net sales represent all Full-line Store sales. Direct Marketing net sales represent catalog call center and Internet sales. Net sales from segments below the GAAP quantitative thresholds are attributable primarily to our two other operating segments. Those segments are Outlet and Factory stores and Franchise stores. These segments have never met any of the quantitative thresholds for determining reportable segments and are included in “Corporate and Other.”

[2] Operating income (loss) for the Stores and Direct Marketing segments represents profit before allocations of overhead from the corporate office and the distribution centers, interest and income taxes (“four wall” contribution). Total Company shipping costs to customers of approximately $13.0 million, $17.9 million and $20.8 million for fiscal years 2010, 2011 and 2012, respectively, were recorded to “Sales and marketing, including occupancy costs” in the Consolidated Statements of Income. Operating income (loss) for “Corporate and Other” consists primarily of costs included in general and administrative costs and operating income or loss related to the Outlet and Factory stores and the Franchise stores operating segments. Total operating income represents profit before interest and income taxes.

[3] Per common share amounts for the quarters and the full year have been calculated separately. Accordingly, quarterly amounts may not add to the full year amount because of the effects of rounding.
