The operating segments reported below are our segments for which separate financial information is available and for which segment results are evaluated regularly by our Chief Executive Officer in deciding how to allocate resources and in assessing performance. We evaluate segment performance based on consolidated revenues and operating income. Net sales of our business segments exclude intersegment sales as these activities are eliminated in consolidation. Corporate expenses are primarily selling, general and administrative expenses not allocated to segments. Our segment information is as follows (in thousands):
