Industry Segments

6. Industry Segments

Our reportable segments are business units that offer different products and are managed separately because each business requires different technology and marketing strategies. Our reportable segments are: semiconductor equipment, microwave communications and video cameras.

We allocate resources and evaluate the performance of segments based on profit or loss from operations, excluding interest, corporate expenses and unusual gains or losses. Intersegment sales were not significant for any period.

Financial information by industry segment is as follows (in thousands):

A small number of customers historically have been responsible for a significant portion of our total consolidated net sales. During the second quarter of fiscal 2012 one customer of the semiconductor equipment segment represented more than 10% of our consolidated net sales and accounted for 38% of our total consolidated net sales. For the first six months of fiscal 2012, one customer of the semiconductor equipment segment represented more than 10% of our consolidated net sales and accounted for 42% of our total consolidated net sales. During the second quarter of fiscal 2011 one customer of the semiconductor equipment segment represented more than 10% of our consolidated net sales and accounted for 30% of our total consolidated net sales. For the first six months of fiscal 2011, two customers of the semiconductor equipment segment each represented more than 10% of our consolidated net sales and, combined, they accounted for 45% of our total consolidated net sales.
